PLANNING COMMISSION
AGENDA REPORT
AGENDA ITEM NUMBER: 4.2
MEETING DATE: April 12, 2022
CASE/FILE NUMBER: Continued use of teleconferencing in
accordance with Assembly Bill 361 for meetings
of the Planning Commission subject to State
open meeting laws
BACKGROUND/ANALYSIS:
The Ralph M. Brown Act (“Brown Act”) requires that all meetings of a legislative body of
a local agency be open and public, that a physical location for such meetings be
provided, and that the public be permitted to provide public comment during the
meetings – with some exceptions as defined under the law.
Due to the continued impact of the COVID-19 pandemic, the California Legislature
passed Assembly Bill 361 (AB 361), which authorizes a local agency to use
teleconferencing without complying with certain teleconferencing requirements imposed
by the Brown Act when: (1) the legislative body of a local agency holds a meeting
during a declared state of emergency; (2) when state or local health officials have
imposed or recommended measures to promote social distancing; and/or (3) when a
local agency has determined that meeting in person would present imminent risks to the
health or safety of attendees.
The Planning Commission first utilized the provisions of AB 361 on February 2 2, 2022.
In order to continue to have the ability to use the modified teleconferencing options,
AB 361 requires that the Planning Commission re-affirm its findings every 30 days.
Conditions under which AB 361 may be utilized continue to exist as describe d in the
attached Resolution (Attachment A). The provisions of AB 361 allowing the modified
teleconferencing will expire January 1, 2024.
RECOMMENDATION:
Adopt the attached Resolution (Attachment A), providing for continued use of
teleconferencing and other formats as defined and in compliance with Assembly Bill 361
for meetings of the Planning Commission.

WHEREAS, in recognition that such public gatherings at such meetings could
accelerate the spread of COVID-19, Governor Newsom’s Executive Orders suspended,

WHEREAS, pursuant to the Emergency Services Act (Government Code sections
8550 et seq.), and Chapter 8.00 of Title 8 of the Diamond Bar Municipal Code, the City
Council of the City of Diamond Bar has proclaimed the continued existence of a local

Project Description
The requested amendments to the previously-approved land use entitlement
applications are summarized below:
• Amendment to Development Review to approve revisions to the site and
architectural designs to accommodate:
o The replacement of the single-story 8,900 square-foot medical office building with
a 6,500 square-foot commercial building to accommodate up to three tenants;
o Minor architectural revisions to the hotel building to accommodate the addition of
15 rooms (approved for 109 rooms and proposing 124 rooms); and
o The addition of a southbound left-turn pocket on Brea Canyon Road to
accommodate left-turn ingress to the Project.
• Amendment to Tentative Parcel Map to eliminate the condominium map
associated with the above-described medical office building.
• Amendment to Conditional Use Permit to approve a drive-thru service lane for
one tenant at the proposed 6,500 square-foot commercial building.
• Amendment to Parking Permit to approve the updates to the shared parking
demand analysis.
• Amendment to Comprehensive Sign Program to approve the refurbishment of an
existing 65-foot-tall pylon sign, addition of a wall sign on the three-story medical
office building, and associated wall signs on the proposed single-story commercial
building.
• Minor Conditional Use Permit to approve the outdoor dining area for the single-
story 6,500 square-foot commercial building.
The applicant requested the above modifications to the Project as a result of shifting
real estate market needs and demand from the COVID-19 pandemic. Some of the
revisions addresses residents’ concerns raised during the public hearings in 2019 , such
as the lack of a left-turn ingress pocket on Brea Canyon Road.
Site Plan: The overall layout of the center remains the same. Access to the site was
provided via an unsignalized right-turn in and right-turn out driveway on Brea Canyon
Road with parking areas centrally located for efficient parking and traffic circulation,

however the applicant is proposing to a dd a southbound left-turn pocket on Brea
Canyon Road to accommodate a left turn in access to the Project.
Parking: There were 289 parking spaces approved to be provided on -site and will
remain unchanged, of which 52 are compact spaces and allocated for employee
parking. A parking permit was approved to share driveway access and parking between
the proposed lots within the development.
Architecture: A contemporary architectural theme was chosen for the Project. The
buildings are designed to incorporate principles of the modern architecture through
simplicity of building form and avoidance of superfluous details. The proposed single -
story commercial building is designed to be consistent with the architectural theme of
the center, incorporating the same palette of colors and materials.
Signage: Detailed conceptual designs for all freestanding and building -mounted signs
were approved as part of a Comprehensive Sign Program (Attachment G), specifying
size, location, and design requirements that are appropriate to the scale and setbacks
of the buildings. The applicant is requesting approval to retain and refurbish an existing
65-foot high pylon sign, add a wall sign on the three -story medical office building, and
add wall signs on the proposed single-story commercial building.

21.20.110, 22.48, 22.30.050, 22.36.060, and 22.56)
As stated, the Project requires amendments to five discretionary entitlement
applications and one new application for review. The previously approved entitlements
require Planning Commission approval, and the one new entitlement (Minor Conditional
Use Permit for outdoor dining) require Hearing Officer approval, a position currently held
by the Community Development Director. DBMC Section 22.48.030 of the
Development Code requires all applications to be processed simultaneously by the
highest review authority. Therefore, the Planning Commission will determine whether to
approve the requests described below.
The following analysis sets forth the foundation for the Findings of Fact contained in the
attached resolution. Together, the analysis and findings provide the basis for staff’s
recommendation that the Planning Commission approve the Proje ct and all of its
components, subject to the conditions set forth in the approval resolution.

Amendment to Development Review (DBMC Section 22.48)
The purpose of Development Review (DR) is to establish consistency with the General
Plan through the promotion of high aesthetic and functional standards to complement
and add to the economic, physical, and social character of the City. The process
ensures that new development and intensification of existing development yields a
pleasant living environment, and attracts the interest of residents and visitors as the
result of consistent exemplary design.
The proposed amendment to the DR is to approve the revisions to the site and
architectural design of the replacement of the single -story medical office building with a
new single-story commercial building, and minor architectural revisions to the hotel
building to accommodate the addition of 15 rooms. The approved Project allowed 109
rooms and is now proposing 124 rooms. There are no major exterior changes to the
four-story hotel building, and the building footprint did not change. There are areas
where the building is pushed out to accommodate the additional rooms, but the
elevations changes are minimal, keeping the same architectural features of the
approved design.

*The Planned Development Overlay District allows for modifications to the parking
requirement. Additionally, the Project will provide adequate parking by means of a
shared parking arrangement with the proposed parcels. The conditions of approval
require a reciprocal parking and access agreement to be recorded with the final map.
Amendment to Tentative Parcel Map (DBMC Section 21.20.110)
Pursuant to Section 66424 of the Subdivision Map Act, a Tenta tive Parcel Map is
required for the subdivision of any units/parcels of improved land for the purpose of
sale, lease or financing. A Tentative Parcel Map was approved to subdivide the lot into
three separate parcels to allow each parcel to be sold off and separately owned and
one parcel to be owned in common ; and to create a condominium subdivision of air
space for the three-story office building and single-story medical office building. The
common lot includes the driveway access, internal circulation sy stem, parking, open
spaces, easements and utilities. The proposed amendment is requested to eliminate
the condominium subdivision for the single-story medical office building, since the
building is proposed to be replaced with a single-story commercial building.
Amendment to Conditional Use Permit (DBMC Section 22.58)
A CUP is required for uses whose effect on the surrounding area cannot be determined
before being analyzed for suitability at a particular location. When reviewing a CUP,
consideration is given to the location, design, configuration, operational characteristics
and potential impacts to determine whether or not the proposed use will pose a
detriment to the public health, safety and welfare. If it can be found that the proposed
use is likely to be compatible with its surroundings, the Commission may approve the
proposed use subject to conditions stipulating the manner in which the use must be
conducted. If the Commission finds that the proposed use is likely to be detrimental to
the general peace, health and general welfare, then it must deny the request.
A CUP is required for approval of a drive -thru service lane that wraps around the
proposed single-story commercial building. The proposed drive-thru service lane has
adequate vehicle queuing length to accommodate the expected demand in order to
reduce the likelihood of vehicle stacking obstructing parking lot travel lanes. 13 vehicle
queuing spaces are available, which is adequate to accommodate the expected
demand. Cars queuing in the drive-thru lane will be screened from view along Brea
Canyon Road by a landscaped buffer. In addition, there is sufficient turning radii in the
drive-thru aisle for vehicles to maneuver and turn in the lane.

Queuing Analysis
The following conditions of approval are recommended to prevent potential noise, odor,
parking or other land-use impacts to nearby residences:
1. A six-foot decorative concrete block wall shall be constructed along the north
property line abutting the Farmer Boy’s property;
2. No external speakers such as the menu (order) board, speaker post, and pick -up
window typically associated with the operation of the proposed drive-thru lane
shall be directly oriented or skewed toward proximal residential areas to the north
and west of the project site. All such speakers shall be equipped with an
automatic volume control (AVC) system, as pre-approved by the Community
Development Director, designed to adjust speaker volume levels based on
ambient noise levels and automatically lowerin g noise levels during time periods
when ambient noise is low, particularly at night. Prior to the issuance of building
permits, the location and direction of the exterior menu boards and speaker posts
shall be reviewed and approved by the Community Development Director;

property owner, operator, franchisee, licensee, and/or master lease of the
business(es), shall submit an odor management and control plan (OMCP),
including a listing of the proposed exhaust systems and the manufacturer’s
specifications associated therewith; and the siting and positioning of any outdoor
venting outlets of those exhaust control systems, subject to the review and
approval of the Community Development Director. The OMCP shall include an
exhaust air filtration system with odor controls preventing or minimizing the
discharge of internal odors and any associated air pollutants from being
externally emitted. The exhaust outlet shall be located to promote upward
discharge so that emissions therefrom can be adequately dispersed and neither
cause nor contribute to an odor nuisance; and
4. If, at any time, the City finds that the drive-thru lane and/or outdoor dining area is
the cause of a parking deficiency, noise nuisance, or other land -use impact,
within or beyond the subject property boundaries, the Community Development
Director after providing the entitlement holder a reasonable opportunity to
mitigate the impact(s) to an acceptable level, may refer the matter back to the
Planning Commission to consider amending this Conditional Use Permit and
Minor Conditional Use Permit to address such impacts.
Amendment to Parking Permit (DBMC Section 22.30.050)
Pursuant to DBMC Section 22.30.050 of the Development Code, where two or more
commercial uses are developed as a professional center and those uses have distinct
and differing peak parking usage periods, a reduction in the required nu mber of parking
spaces may be allowed through the approval of a parking permit, provided that the most
remote space is located within 300 feet of the use it is intended to serve (as measured
along the most direct pedestrian path). The amount of reduction may be up to the
number of spaces required for the least intensive of the two or more uses sharing the
parking.
The approved Parking Permit is being updated to reflect the changes to the shared
parking demand analysis due to the change in the single -story commercial building from
a medical office use to retail and fast-food restaurant uses, as well as the change in the
three-story professional office building from a mix of medical and professional office
uses to all medical office uses.
Because there is a deficit number of parking spaces when shared parking dynamics are
not factored in, staff required a parking study to analyze the parking demand through
the application of a shared parking concept. The applicant submitted an updated
parking study (Attachment E), prepared and signed by a licensed traffic engineer, that
provides parking demand calculations based on survey data collected at a similar hotel
site in conjunction with the Urban Land Institute’s Shared Parking (2nd Edition)
methodology.

There are 289 spaces proposed on-site, of which 53 are compact spaces and are
proposed to be allocated for employee parking. Based on the parking studies
assessing the projected peak weekday parking demand of 289 spaces, there will be a
balanced condition with a surplus of 0 spaces; and the peak weekend parking demand
totals 278 spaces, which results in a surplus of 11 spaces. The proposed development
will adequately meet the overall parking demand by providing 289 spaces for all parcels.
To ensure that adequate parking is available for customers and employees of the Brea
Canyon Business Center, a Parking Management Plan will be developed that identifies
the proposed employee parking spaces and key management strategies such as short
term/time restricted spaces to maximize the availability of parking for customers of the
center.
The applicant is required to submit a reciprocal parking and access agreement
governing the use and access of all common driveways, parking, and easement areas.
The agreement will be reviewed and approved by the Planning Division and City
Attorney’s Office prior to issuance of building permits.
Traffic Impacts:
Access to the Project site was provided via a one right-turn in and right-turn out
unsignalized driveway on Brea Canyon Road. A raised landscaped central median was
to be constructed along Brea Canyon Road in order to prevent vehicles from turning left
to exit the Project site, as well as those traveling southbound along Brea Canyon Road
from turning left into the Project site. In response to the residents’ concerns raised
during the public hearings in 2019, the applicant is proposing to add a southbound left -
turn pocket on Brea Canyon Road so that travelers no longer need to make a U -turn on
Golden Springs Drive to access the site. Left-turn out of the Project site will continue to
be prohibited as previously approved.

Amendment to Comprehensive Sign Program (DBMC Section 22.36.060)
Comprehensive Sign Programs are used to integrate the signage with the design of the
development to achieve a unified architectural statement. The approved CSP has
specific requirements for the signs proposed for the development. The proposed
revisions to the CSP, including conceptual designs, are included in Attachment G. The
proposed CSP revisions are listed below:
1. Retain the existing 65-foot-high freestanding pylon sign for the fast-foot
restaurant tenant and refurbish the exterior with paint colors and sto ne veneer to
match the rest of the buildings in the center;
2. Add a wall sign on the north elevation of the three -story medical office building to
provide visibility along the SR-60 freeway; and
3. Add three wall signs on the east (front) and west (rear) elevations of the single-
story commercial building for each tenant.
The table below shows the proposed CSP revisions in bold, together with the
previously-approved sign program elements:

Proposed Signage
*This is an existing legal non-conforming structure.
The proposed amendment to the CSP satisfies the purpose and intent of the
Development Code by integrating the signage with the design of the building and having
specific size, location, and design requirements for freestanding and building -mounted
signs. The revisions are appropriate to the scale and setbacks of the buildings, and are
placed so they respect and harmonize with the architectural elements onto which th ey
will be mounted or constructed.

Minor Conditional Use Permit (DBMC Section 22.56)
An MCUP is required for uses whose effect on the surrounding area cannot be
determined before being analyzed for suitability at a particular location. When reviewing
an MCUP, consideration is given to the location, design, configuration, operational
characteristics and potential impacts to determine whether or not the proposed use will
pose a detriment to the public health, safety and welfare.
The proposed outdoor dining area in front of the single-story commercial building is
approximately 260 square feet, and is located approximately 116 feet away from the
nearest residential property—separated by the Los Angeles County Flood Control
District channel and proposed six-foot high concrete block wall—which reduces
potential noise and compatibility problems. Entertainment of any kind will not be
permitted. Therefore, the operating characteristics will be compatible with the existing
and future uses within the surrounding area. Furthermore, the proposed conditions of
approval will mitigate potential noise or other land use impacts of this use to nearby
residents.

Additional Review
The Public Works/Engineering Department and Building and Safety Division, as well as
the County of Los Angeles Fire Department reviewed this Project and included their
comments in the attached resolution as conditions of approval.
ENVIRONMENTAL ASSESSMENT:
The previously approved Project was reviewed for compliance with the California
Environmental Quality Act (CEQA). Based on that assessment, the City prepared an
Initial Study and filed a Notice of Intent to Adopt a Mitigated Negative Declaration
(MND) for the Project with the Office of Planning and Research and the Los Angeles
County Clerk on September 19, 2019. On November 19, 2019, the Mitigated Negative
Declaration was adopted and the development application was approved. A Notice of
Determination was filed and posted on November 20, 2019. No CEQA challenge was
filed.
Under CEQA Guidelines Section 15164, an addendum to an adopted MND may be
prepared if only minor technical changes or additions are necessary or none of the
conditions calling for the preparation of a subsequent negative declaration or
Environmental Impact Report (EIR) have occurred. Under Section 15162, the City shall
prepare an EIR if there are any new significant environmental effects associated with
the refined project. With respect to the proposed Project, the revisions are only minor
technical changes that do not result in any new significant environmental effect(s).
Pursuant to Public Resources Code Section 21166 and CEQA Guidelines 15162, the
City analyzed whether the revisions would result in new significant impacts or
substantial increase in severity of previously identified impacts. Based on the City’s
analysis, no subsequent EIR, supplemental EIR, or subsequent mitigation negative
declaration is required. As a result, the City’s analysis and conclusions are documented
in an Addendum to the previously adopted MND (Attachment D).
NOTICE OF PUBLIC HEARING:
Public hearing notices were mailed to property owners within a 700 -foot radius of the
Project site on March 11, 2022, and to the residents who have previously attended the
Planning Commission and City Council hearings and community meeting. The notice
was also published in the San Gabriel Valley Tribune newspaper on April 1, 2022. The
Project site was posted with a notice display board, and a copy of the public notice was
posted at the City’s designated community posting sites.

California Code of Regulations.
C. FINDINGS OF FACT
Based on the findings and conclusions set forth herein and as prescribed under
Diamond Bar Municipal Code (DBMC) Sections 21.20.110, 22.48, 22.58.040,
22.30.050, 22.36.060, and 22.56.040 this Planning Commission hereby finds and
approves as follows:
Development Review Findings (DBMC Section 22.48)
1. The design and layout of the proposed development are consistent with the
General Plan, development standards of the applicable district, design
guidelines, and architectural criteria for special areas (e.g., theme areas, specific
plans, community plans, boulevards or planned developments).
The Project is consistent with the applicable elements of the City’s General Plan,
City Design Guidelines, development standards in the previously approved
planned development overlay zoning district. The Project, as designed, is
deemed to be the best layout due to the size and configuration of the lot. The
Project is designed in a contemporary modern style of architecture and
incorporates principles of the modern architecture by its simplicity of building form
and windows with non-superfluous details. The Project provides 360-degree
architectural articulation with a high level of attention to building details and
finishes as well as incorporate signage to be compatible with the design motif of
the buildings. The project site is not a part of any theme areas, specific plans,
community plans, boulevards or planned developments.
2. The design and layout of the proposed development will not interfere with the use
and enjoyment of neighboring existing or future developments, and will not create
traffic or pedestrian hazards.
The Project will not interfere with the use or enjoyment of neighboring existing or
future developments because the following conditions of approval are
7.1.a
Packet Pg. 32

PC Resolution No. 2022-XX
recommended to prevent potential noise, odor, parking or other land-use impacts
to nearby residences:
• A six-foot decorative concrete block wall shall be constructed along the north
property line abutting the Farmer Boys property. A six-foot decorative
concrete block wall is proposed to be constructed a long the north property
line, along the Los Angeles County Flood Control District channel.
• No external speakers such as the menu (order) board, speaker post, and pick -
up window typically associated with the operation of the proposed drive -thru
lane shall be directly oriented or skewed toward proximal residential areas to
the north and west of the project site. All such speakers shall be equipped
with an automatic volume control (AVC) system, as pre-approved by the
Community Development Director, designed to adjust speaker volume levels
based on ambient noise levels and automatically lowering noise levels during
time periods when ambient noise is low, particularly at night. Prior to the
issuance of building permits, the location and direction of the exterio r menu
boards and speaker posts shall be reviewed and approved by the Community
Development Director;
• Prior to the issuance of building permits for any restaurant -related
business(es) proposed on the project site, the project proponent, as
represented by the property owner, operator, franchisee, licensee, and/or
master lease of the business(es), shall submit an odor management and
control plan (OMCP), including a listing of the proposed exhaust systems and
the manufacturer’s specifications associated therewith; and the siting and
positioning of any outdoor venting outlets of those exhaust control systems,
subject to the review and approval of the Community Development Director.
The OMCP shall include an exhaust air filtration system with odor controls
preventing or minimizing the discharge of internal odors and any associated
air pollutants from being externally emitted. The exhaust outlet shall be
located to promote upward discharge so that emissions therefrom can be
adequately dispersed and neither cause nor contribute to an odor nuisance;
and
• If, at any time, the City finds that the drive-thru lane and/or outdoor dining area
is the cause of a parking deficiency, noise nuisance, or other land -use impact,
within or beyond the subject property boundaries, th e Community
Development Director after providing the entitlement holder a reasonable
opportunity to mitigate the impact(s) to an acceptable level, may refer the
matter back to the Planning Commission to consider amending this
Conditional Use Permit and Minor Conditional Use Permit to address such
impacts.
The Project will not cause any intersections or street segments in the vicinity to
operate at an unacceptable level of service with the following traffic
improvements required to be constructed:
• Add a southbound left-turn pocket on Brea Canyon Road to accommodate a
left-turn in access to the Project.
• Restriping of the northbound approach to westbound Lycoming Street along
7.1.a
Packet Pg. 33

PC Resolution No. 2022-XX
Brea Canyon Road to the north of the Project’s driveway to provide an
additional exclusive westbound left-turn lane.
• In response to the addition of a second exclusive left-turn lane to the west of
Brea Canyon Road, along Lycoming Street, the restriping of the westbound
lane to accommodate two receiving lanes.
• Relative to eastbound Lycoming Street, west of Brea Canyon Road, restriping
of the existing eastbound shared left/through/right-turn lane to provide an
exclusive left-turn lane and a separate shared through/right-turn lane.
3. The architectural design of the proposed development is compatible with the
character of the surrounding neighborhood and will maintain and enhance the
harmonious, orderly and attractive development contemplated by this chapter,
the general plan, or any applicable specific plan.
The Project is designed to be compatible with the surrounding neighborhood and
minimize any potential negative impacts but also elevates the architectural
character of the area. The proposed single-story commercial building is designed
to be consistent with the architectural theme of the center, incorporating the same
palette of colors and materials. The architectural style is a contemporary modern
style and designed to incorporate principles of the modern architecture by its
simplicity of building form and windows with non-superfluous details. The Project
provides 360-degree architectural articulation with a high level of attention to
building details and finishes and also incorporates signage to be compatible with
the design motif of the buildings. The Project will also construct attractive
streetscape improvements along the Project frontage such as street trees,
decorative interlocking pavers and theme rails. The design and appearance of
the Project is compatible and will enhance the surrounding community.
4. The design of the proposed development will provide a desirable environment for
its occupants and visiting public as well as its neighbors through good aesthetic
use of materials, texture and color, and will remain aesthetically appealing.
See Response 3 above.
5. The proposed development will not be detrimental to the public health, safety or
welfare or materially injurious (e.g., negative effect on property values or resale(s)
of property) to the properties or improvements in the vicinity.
Before the issuance of any City permits, the Project is required to comply with all
conditions within the approval resolutions, and the Building and Safety Division
and Public Works Departments, and L.A. County Fire Department requirements.
The referenced agencies through the permit and inspection process will ensure
that the Project is not detrimental to the public health, safety or welfare or
materially injurious to the properties or improvements in the vicinity.
6. The proposed project has been reviewed in compliance with th e provisions of the
California Environmental Quality Act (CEQA).
Pursuant to Public Resources Code Section 21166 and CEQA Guidelines 15162,
the City analyzed whether the revisions would result in new significant impacts or
substantial increase in severity of previously identified impacts. Based on the
City’s analysis, EIR or subsequent mitigated negative declaration is required. As

a result, the City’s analysis and conclusions are documented in an Addendum to
the previously adopted MND.
Tentative Map Findings: Pursuant to Subdivision Code Section 21.20.110 of the City’s
Subdivision Ordinance, the Planning Commission makes the following findings:
1. The proposed subdivision, together with the provisions for its design and
improvement, is consistent with the general plan and any applicable specific plan.
The Project involves the subdivision of the lot into four separate parcels and the
condominium subdivision of air space for one office building. The three -story
office building will subdivide air space for 34 medical office units. The current
General Plan land use designation for the Project site is General Commercial (C)
and zoning district is Regional Commercial-Planned Development Overlay
District (C-3-PD), which allows for a new commercial development consisting of
a 124-room, four-story hotel; a 47,642 square-foot, three-story medical office
building, and a 6,500 square-foot single-story commercial building. The Project
site is not a part of any specific plan.
2. The site is physically suitable for the type and proposed density of development.
The Project is consistent with the General Plan land use designation of General
Commercial (C), which allows for regional, freeway-oriented, and/or community
retail and service commercial uses. The Project is located within an urbanized
area adequately served by existing roadways and infrastructure. Therefore, the
property is physically able to accommodate the proposed development.
3. The design of the subdivision or the proposed improvements will not cause
substantial environmental damage or injure fish or wildlife or their habitat.
The design of the subdivision or the proposed improvements will not cause
substantial environmental damage or injure fish or wildlife or their habitat because
the existing site is located in an urbanized area that does not contain habit ats or
would otherwise injure fish or wildlife or their habitat.
4. The design of the subdivision or type of improvements will not cause serious
public health or safety problems.
The proposed subdivision or type of improvements are not likely to cause serious
public health or safety problems because the existing site is located in an
urbanized area and is consistent with other similar improvements in the area.
5. The design of the subdivision or type of improvements will not conflict with
easements, acquired by the public at large for access through or use of, property
within the proposed subdivision.
The Project site has a Caltrans storm drain easement that runs diagonally
through the site from the south to the existing northern Los Angeles County flood
control channel that will be relocated. Storm drain connections to and/or
construction activities encroaching into a LACFCD easement require a County
permit.
6. The discharge of sewage from the proposed subdivision into the community
7.1.a
Packet Pg. 35
7
PC Resolution No. 2022-XX
sewer system would not result in violation of existing requirements prescribed by
the California Regional Water Quality Control Board.
As part of the environmental review process, the City received will -serve letters
from the Walnut Valley Water District and the County Sanitation Dist ricts of Los
Angeles County. The Project is conditioned to obtain connection permit(s) from
the City and County Sanitation District prior to issuance of building permits.
7. A preliminary soils report or geologic hazard report does not indicate adverse soil
or geologic conditions.
The Project is not located within any known landslide hazard area, and all
buildings will conform to applicable earthquake design regulations in the 201 9
California Building Code as well as conform to and be consistent with the
recommended seismic parameters and recommended design and development
standards identified in the preliminary geotechnical report.
A preliminary geotechnical report was submitted and indicated a potential for
liquefaction of layers of sandy soils at the northwest corner of the project site. A
mitigation measure is included in the adopted Mitigation Reporting and
Monitoring Program to reduce any potential hazards and liquefaction settlements.
8. The proposed subdivision is consistent with all applicable provisions of the City’s
subdivision ordinance, the development code, and the subdivision map act.
The Project is consistent with the City’s subdivision ordinance, subdivision map
act, and applicable development code.
9. There has been a change of circumstances related to the original approval.
The applicant requested the modifications to the Project as a result of shifting real
estate market needs and demand from the COVID -19 pandemic. Some of the
revisions address residents’ concerns raised during the public hearings in 2019.
Conditional Use Permit Findings (DBMC Section 22.58.040)
1. The proposed use is allowed within the subject zoning district with the approval
of a conditional use permit and complies with all other applicable provisions of
this Development Code and the Municipal Code.
The proposed drive-thru service lane that wraps around the proposed single-story
commercial building is subject to a Conditional Use Permit. The proposed drive-
thru service lane has adequate vehicle queuing length to accommodate the
expected demand in order to reduce the likelihood of vehicle stacking obstructing
parking lot travel lanes. Thirteen (13) vehicle queuing spaces are available,
which is adequate to accommodate the expected demand of vehicular traffic.
Cars queuing in the drive-thru lane will be screened from view along Brea Canyon
Road by a landscaped buffer. In addition, there is sufficie nt turning radii in the
drive-thru aisle for vehicles to maneuver and turn in the lane. In addition,
conditions of approval are incorporated to prevent potential noise, odor, parking
or other land-use impacts to nearby residences.
2. The proposed use is consistent with the General Plan and any applicable specific
7.1.a
Packet Pg. 36
8
PC Resolution No. 2022-XX
plan.
The C-3-PD zoning district allows for large-scale commercial uses serving
residents and businesses within the region including a broad spectrum of land
uses including hotels, offices, retail and restaurant tenants with drive-thru service
and will be consistent with the General Plan land use designation of General
Commercial (C). There is no specific plan proposed as part of this development.
3. The design, location, size, and operating characteristics of the proposed use are
compatible with the existing and future land uses in the vicinity.
The Project will not interfere with the use or enjoyment of neighboring existing or
future developments because conditions of approval are incorporated to prevent
potential noise, odor, parking or other land-use impacts to nearby residences.
See also Response 1 above.
4. The subject site is physically suitable for the type and density/intensity of use
being proposed including access, provision of utilities, compatibility with adjoining
land uses, and the absence of physical constraints.
The Project is consistent with the General Plan land use designation of General
Commercial and the zoning designation of Regional Commercial-Planned
Development Overlay, which allows for the development of retail and restaurant
uses with drive-thru service. The Project Site is located within an urbanized area
adequately served by existing roadways and infrastructure. The Project will not
cause any intersections or street segments in the vicinity to operate at
unacceptable level of service with the proposed conditions of approval and
adopted mitigation measures and improvements required as part of the Project
approval. All utility services will be provided to the property.
5. Granting the conditional use permit will not be detrimental to the public interest,
health, safety, convenience, or welfare, or injurious to persons, property, or
improvements in the vicinity and zoning district in which the property is located.
Prior to the issuance of any City permits, the Project is required to comply with
all conditions within the approval resolutions, and the Building and Safety Division
and Public Works Departments, and L.A. County Fire Department requirements.
The referenced agencies through the permit and inspection process will ensure
that the Project is not detrimental to the public health, safety or welfare or
materially injurious to the properties or improvements in the vicinity.
6. The proposed project has been reviewed in compliance with the provisions of the
California Environmental Quality Act (CEQA).
Pursuant to Public Resources Code Section 21166 and CEQA Guidelines 15162,
the City analyzed whether the revisions would result in new significant impacts or
substantial increase in severity of previously identified impacts. Based on the
City’s analysis, no EIR or subsequent mitigated negative declaration is required.
As a result, the City’s analysis and conclusions are documented in an Addendum
to the previously adopted MND.
Parking Permit Findings (DBMC Section 22.36.060)
7.1.a
Packet Pg. 37
9
PC Resolution No. 2022-XX
1. The intent of the parking regulations, which is to ensure that sufficient parking will
be provided to serve the use intended and potential future uses of the subject
site, is preserved.
Based on parking studies assessing the projected peak parking demands, and
parking utilization data/surveys for the hotel component with the office uses, the
Project will adequately meet the overall parking demand by providing 289 spaces
for all uses. To ensure that adequate parking is available for customers and
employees of the Brea Canyon Business Center, a Parking Management Plan
will be developed that identifies the proposed employee parking spaces and key
management strategies such as short term/time restricted spaces to maximize
the availability of parking for customers and employees of the center. The
applicant is required to record a City-approved reciprocal parking and access
agreement governing the use and access of all common driveways, parking, and
easement areas prior to the issuance of building permits.
2. A parking permit is approved in compliance with Section 22.30.050 (Reduction of
off-street parking requirements for shared uses).
See Response 1 above. Since there is a deficit number of parking space s when
shared parking dynamics are not factored in, a parking study was prepared to
analyze the parking demand through the application of a shared parking concept.
The applicant submitted a parking study that provides parking demand
calculations based on survey data collected at a similar hotel site and the Urban
Land Institute’s Shared Parking (2nd Edition) methodology signed by a licensed
traffic engineer.
As stated, there are 289 spaces proposed on-site, of which 53 are compact
spaces and are proposed to be allocated for employee parking. Based on the
parking studies assessing the projected peak weekday parking demand of 289
spaces, there will be a surplus of 0 spaces; and the peak weekend parking
demand totals 278 spaces, which results in a surplus of 11 spaces. An alternative
assessment was done to ensure that adequate parking is provided using parking
utilization data/surveys for the hotel component with the office uses, resulting in
a surplus of 62 spaces on weekdays and 144 spaces on weekends. The
proposed development will adequately meet the overall parking demand by
providing 289 spaces for all parcels. To ensure that adequate parking is available
for customers and employees of the Brea Canyon Business Center, a Parking
Management Plan will be developed that identifies the proposed employee
parking spaces and key management strategies such as short term/time
restricted spaces to maximize the availability of parking for customers of the
center.
Comprehensive Sign Program Findings (DBMC Section 22.36.060)
1. The comprehensive sign program satisfies the purpose of this chapter and the
intent of this section.
The comprehensive sign program satisfies the purpose and intent of the
Development Code by integrating the signage with the design of the building and
having specific requirements such as size, location, and design requirement for
freestanding and building-mounted signs. The comprehensive sign program
enhances the overall development by providing size criteria for wall and
7.1.a
Packet Pg. 38
10
PC Resolution No. 2022-XX
monument signs that are appropriate to the scale and setbacks of the buildings,
and are placed so that they respect and harmonize the architectural elements
onto which they will be mounted or constructed. The revisions include retaining
an existing 65-foot high freestanding pylon sign for the fast-food restaurant tenant
and refurbishing the structure with paint colors and stone veneer to the buildings
in the center; adding a wall sign on the north elevation of the three-story medical
office building to provide visibility along the SR-60 freeway; and adding three wall
signs on the east (front) and west (rear) elevations of the proposed single-story
commercial building for each tenant.
2. The signs enhance the overall development, are in harmony with, and are visually
related to other signs included in the comprehensive sign program and to the
structure and/or uses they identify, and to surrounding development.
The proposed revisions satisfies the purpose and intent of the Comprehensive
Sign Program by integrating the signage with the design of the building s and
having specific size, location, and design requirements for freestanding and
building-mounted signs. The revisions are appropriate to the scale and setbacks
of the buildings, and placed so they respect and harmonize with the architectural
elements onto which they will be mounted or constructed.
3. The comprehensive sign program accommodates future revisions which may be
required due to changes in uses or tenants.
The comprehensive sign program accommodates future revisions by having
minor changes reviewed by staff and the Community Development Director, and
any major changes to be reviewed by the Planning Commission.
4. The comprehensive sign program complies with the standards of this chapter,
except that flexibility is allowed with regard to sign area, number, location, and/or
height to the extent that the comprehensive sign program will enhance the overall
development and will more fully accomplish the purposes of this chapter.
The comprehensive sign program complies with the standards of DBMC
Chapter 22.36 and will enhance the overall development through consistency
with the City’s Design Guidelines for commercial signage, uniformity and easy
identification of the signs, and neighborhood compatibility.
Minor Conditional Use Permit Findings (DBMC Section 22.56.040)
1. The proposed use is allowed within the subject zoning district with the approval
of a Minor Conditional Use Permit and complies with all other applicable
provisions of this Development Code and the Municipal Code.
Pursuant to DBMC Section 22.10 – Table 2-6, the proposed outdoor dining area
is permitted in the Regional Commercial Planned Development Overlay (C-3-PD)
zone with the approval of a Minor Conditional Use Permit. As conditioned, the
proposed outdoor dining area complies with all other applicable provisions of the
Municipal Code.
2. The proposed use is consistent with the general plan and any applicable specific
plan.
7.1.a
Packet Pg. 39
11
PC Resolution No. 2022-XX
The project site’s land use designation is General Commercial (C). According to
the General Plan, this land use designation provides for regional, freeway-
oriented, and/or community retail and service uses such as restaurants. The
proposed outdoor dining area is considered a service use and as such is
consistent with the General Plan. There is no applicable specific plan for the
project site.
3. The design, location, size and operating characteristics of the proposed use are
compatible with the existing and future land uses in the vicinity.
The outdoor dining area is proposed in front of the single-story commercial
building, located approximately 116 feet away from the nearest residential
property—separated by the Los Angeles County Flood Control District channel
and proposed six-foot high concrete block wall—which reduces potential noise
and compatibility problems. Entertainment of any kind will not be permitted.
Therefore, the operating characteristics will be compatible with the existing and
future uses within the surrounding as conditioned.
4. The subject site is physically suitable for the type and density/intensity of use
being proposed including access, provision of utilities, compatibility with adjoining
land uses, and the absence of physical constraints.
See Response 3 above.
5. Granting the Minor Conditional Use Permit will not be detrimental to th e public
interest, health, safety, convenience or welfare, or materially injurious to persons,
property or improvements in the vicinity and zoning district in which the property
is located.
The proposed outdoor dining area will be subject to the conditions set forth in this
resolution. In light of these facts, the approval of the application will not be
detrimental to the public health, safety or welfare or materially injurious to the
properties or improvements in the vicinity.
6. The proposed project has been reviewed in compliance with the provisions of the
California Environmental Quality Act (CEQA).
Pursuant to Public Resources Code Section 21166 and CEQA Guidelines 15162,
the City analyzed whether the revisions would result in new significant impacts or
substantial increase in severity of previously identified impacts. Based on the
City’s analysis, no subsequent EIR, supplemental EIR, or subsequent mitigation
negative declaration is required. As a result, the City’s analysis and conclusions
are documented in an Addendum to the previously adopted MND.
Based on the findings and conclusions set forth herein and as prescribed under DBMC
Sections 21.20.110, 22.48, 22.58.040, 22.30.050, 22.36.060, and 22.56.040 , this

Background
Site Characteristics
The Project site is on a 5.73 gross acre vacant parcel. The property previously
operated as a recreational vehicle and boat storage use containing two on -site
structures totaling approximately 2,232 square feet. These structures were demolished
in June 2019.
The site is primarily surrounded by existing single-family residential development to the
north, east, and west, the SR-60 freeway to the south, and existing commercial
development to the northwest. The SR-60 descending westbound off-ramp
deck/structure is approximately 10-11 feet above the ground, and runs parallel to the
site. The northerly and easterly residential properties are separated by a Los Angeles
County Flood Control District channel, and the westerly residential properties are
separated by Brea Canyon Road.

Project Description
The applicant is proposing to build a new commercial development consisting of a
business park with a mix of hotel, professional and medical office uses. Several site
plan scenarios with varying building placements, uses, and vehicular ci rculation and
parking layouts were presented and evaluated between the applicant team and staff.
After several iterations, the final site layout reflects input from City staff and consultants,
and addresses residents’ concerns raised during a community meeting hosted by the
applicant.

Prior to the submittal of the application, staff arranged a meeting with the executives
from Farmer Boys (corporate owner of the restaurant property to the north) and the
applicant in an effort to provide shared access between the subject property and the
Farmer Boys lot. Several concerns were raised, including the following:
• A single drive approach on Brea Canyon Road would replace and be located to
the south of the current Farmer Boys driveway location. Farmer Boys were n ot
receptive to doing so.
• There will be impacts to the on-site circulation such as removal of existing
parking spaces, and the queuing in the drive -thru lane currently obstructs the
driveway access on Lycoming Street. These impacts would require the
relocation of the parking spaces and widening of the driveway on Lycoming
Street, but site constraints would inhibit the ability to address these impacts.
Because the challenges and constraints to connecting the two sites would be
excessively burdensome for the neighboring property owners to overcome, the Project
was designed to be a self-contained development.
Please refer to the plans provided in Attachment G for the following discussion.
Site Plan: The layout provides excellent visibility from the freeway while minimizing
potential negative impacts to the residential homes to the north. The tallest buildings
have been placed towards the south property line, farthest away from the residential
properties to the north. Access to the site is provided via an unsignalized right-turn in
and right-turn out driveway on Brea Canyon Road with parking areas centrally located
for efficient parking and traffic circulation. Building entrances have been oriented
towards parking areas for ease of access and wayfinding.
Subdivision: The parcel will be subdivided into four lots to accommodate the following
uses:
• Four-story Hilton Hampton Inn and Suites hotel with 109-rooms;
• Three-story professional office building with subdivision of air space for
34 medical and general office units;
• One-story medical office building with subdivision of air space for two medical
office units; and
• Common lot for driveway access, parking, utility systems, and other areas to be
owned in common by a property owners association.
The office units will be sold as office condominiums governed by a separate
condominium association.

Grading: Grading activities include approximately 8,000 cubic yards of cut and
8,000 cubic yards of fill, which balances the site. Excavation will include c uts to remove
undocumented fills, excavations for building foundations, and trenching for new utility
lines. Undocumented fills and portions of the compressible natural soils will be removed
and replaced with properly compacted fill.
Parking: There are 289 parking spaces proposed to be provided on-site, of which
52 are compact spaces and allocated for employee parking. The applicant is requesting
a parking permit to share driveway access and parking between the proposed lots
within the development.
Architecture: A contemporary architectural theme was chosen for the Project. The
buildings are designed to incorporate principles of the modern architecture through
simplicity of building form and avoidance of superfluous details. Facades are
articulated, with changes in roof height, wall planes, window composition, wall materials
and colors. The architectural articulation and visual quality of the street facades are
continued on all sides of all buildings. Metal accents, wood cladding, stone veneer,
glass and building colors will be consistent for all three buildings to provide a cohesive,
unified design.
The entrance/lobby area to the hotel building is accentuated by a white fiber cement
siding panels with a cantilevered canopy at the building entrance, bringing this element
down to a human scale. The tall glazed openings have mullions to break up the large
glass panels, and wood laminate panels, stone veneer and reveals are added on the
elevations to break up the flat walls.

Building Height: The four-story hotel building is 64 feet to the top of the parapet; the
three-story office building is approximately 55 feet to the top of the mechanical screen
wall; and the one-story medical office building is 20 feet to the top of the parapet.
Landscaping: There are 95 existing mature trees within the site, none of which are
native or protected. According to the arborist report, five are dead and the other 90 are
in poor condition due to drought stress, under-pruning, and poor pruning, so all 95 trees
will be removed. A total of 221 new trees will be planted.
The proposed conceptual landscape plan offers an extensive mix of trees, shrubs and
groundcovers that provide variations in color, height and textures. The landscape will
be enhanced by adding more trees, shrubs, and ground cover throughout the property.

Nine 36-inch box London plane trees are proposed along the Project site entry, six
24-inch box Muskogee crape myrtle trees are proposed along the Brea Canyon Road
street frontage, in addition to seven 24-inch box Australian willow street trees. Ten
different species of trees being proposed. Southern live oak trees are proposed
throughout the parking areas to associate the site with the landscape character of
Diamond Bar. Although the existing trees located along the north property line, adjacent
to the County flood control channel will be removed, the applicant will be planting a
double row of 36-inch Mondell pine and Brisbane box trees to provide screening for the
residences on Lycoming Street and Dryander Drive, located directly across the flood
control channel. All other plant types proposed are non-invasive plant species. The
majority of the plant palette consists of low water use plants, and is required to comply
with the water-efficient landscape requirements, which will be verified during building
plan check.
The south property boundary will provide a variety of evergreen trees and shrubs to
provide year-round screening and color. The proposed six-foot high block wall along
the south property line will be smooth stuccoed and articulated with landscaped pockets
with flowering vines planted every 50 feet to soften the hard wall surfaces when viewed
from the public right-of-way. Additionally, the Caltrans owned and maintained slope
directly adjacent to the southern boundary that runs parallel to the existing SR60
westbound offramp will be landscaped with a variety of shrubs and irrigated to provide
an attractive visual statement from Brea Canyon Road. Currently, the area has very
little vegetation and is not adequately maintained. The applicant is required to install
the landscape improvements as specified in the conceptual landscape plans and
maintain the area. The City will be entering into a landscape maintenance agreement
with Caltrans and another agreement with the property owner requiring the landscaping
in the Caltrans ROW to be installed and maintained by the property owner.

ANALYSIS:
Review Authority (Diamond Bar Municipal Code (DBMC) Sections 22.70, 22.32,
22.58, 21.20.080, 22.48, 22.30.050, and 22.36.060)
As stated, the Project requires seven discretionary entitlement applications for review.
Three entitlements (General Plan Amendment, Zone Change and Tentative Parcel
Map) require City Council approval, and the other four entitlements (Conditional Use
Permit, Development Review, Parking Permit and Comprehensive Sign Program)
require Planning Commission approval. DBMC Section 22.48.030 of the Development
Code requires all applications to be processed simultaneously by the highest review
authority. Therefore, the Planning Commission’s role in this matter is to forward a
recommendation to the City Council for the seven discretionary entitlements described
below.
The following analysis sets forth the foundation for the Findings of Fact contained in the
attached resolutions. Together, the analysis and findings provide the basis for staff’s
recommendation that the Planning Commission recommend approval of the Project and
all of its components, subject to the conditions set forth in the approval resolutions.
7.1.c
Packet Pg. 77
Brea Canyon Business Park Project - Planning Case No. PL2017-169
Page 11 of 27
General Plan Amendment (DBMC Section 22.70)
The General Plan Amendment is a request to change the land use designation from
Professional Office (OP) to General Commercial (C). The City’s General Plan, adopted
on July 25, 1995, is a long-range planning document developed as a comprehensive
growth-management and community development strategy. It defines citywide policies
that are achieved through subsequent community plans, ordinances, standards and
guidelines, studies, capital improvements, economic development and other pertinent
programs. The adopted policies of the General Plan guide the physical development
pattern and promote the necessity of adequate public services and facilities.
The General Plan is the controlling document. The preparation, adoption,
implementation and maintenance of the General Plan aids in informing developers,
citizens, decision-makers, and others of the rules that will guide development, and
provide a basis for local government judgments. All land use decisions of the City have
a direct correlation to the established goals and policies of the General Plan.
The existing General Plan land use designation is Professional Office (OP), which
allows for the establishment of office-based working environments for general,
professional, and administrative offices, as well as support uses. The proposed land
use designation is General Commercial (C), which provides for regional, freeway -
oriented, and/or community retail and service commercial uses. Adjacent land use
designations are General Commercial (C) and Low Medium Residential (RLM). Given
the highly visible location adjacent to the freeway and its proximity to the freeway
offramp providing additional exposure and convenient access to the traveling public, the
land use designation is being changed to allow for a hotel use at this site. Staff believes
that the proposed amendment represents a logical, appropriate and rational land use
designation, which is consistent with the land use designations directly to the northwest.
Relationship to the Comprehensive General Plan Update
Although the City is currently in the process of updating the General Plan (which also
proposes to redesignate the subject property to General Commercial). The Update has
not yet been adopted by the City Council. As such, the Project must be consistent with
the adopted 1995 General Plan, which requires the Land Use Map to be concurrently
amended.
Zone Change (DBMC Section 22.32)
Zoning is the division of a city into districts and the prescription and application of
different regulations in each district. These zoning regulations are generally divided into
two classes: 1) those which regulate the height and bulk of buildings within certain
designated districts, and 2) those which prescribe the use to which buildings within
certain designated districts may be put. The purpose of zoning is the attainment of unity
in the construction and development of a city, along reasonable regulations which tend
to promote the health, safety and general welfare of the community.
7.1.c
Packet Pg. 78
Brea Canyon Business Park Project - Planning Case No. PL2017-169
Page 12 of 27
A Zone Change is being requested to change the zoning district from Light Industry (I)
to Regional Commercial-Planned Development Overlay (C-3-PD). The existing zoning
allows for light industrial/manufacturing uses including research and development,
office-based industrial uses, business support services, and commercial uses requiring
larger sites than are available in the commercial zoning districts. The existing zoning is
also inconsistent with the current General Plan land use designation of OP. The
proposed C-3 zoning district allows for large-scale commercial uses serving residents
and businesses within the region including a broad spectrum of land uses, including
retail stores, restaurants, hotels and offices, and will be consistent with the proposed
General Plan land use designation of General Commercial (C).
An overlay district constitutes a zoning tool to control and regulate the use of property.
It can be used to stimulate development, encourage superior land uses, and promote
high quality development. To promote and facilitate the orderly development of a
prominent, freeway off-ramp adjacent site, the overlay district provides for flexibility in
the site planning and design of the proposed Project.
Conditional Use Permit (DBMC Section 22.58)
A CUP is required for all development proposed on a site subject to a Planned
Development Overlay district to allow for modifications to any of the City’s development
standards including minimum lot area, setbacks, site coverage, floor area ratio, height
limits, landscaping, or off-street parking. The proposed Project is requesting
modifications as follows:
• Exceed the building height limit to allow a 64’ high, four-story hotel and 55’-2”
high, three-story office buildings (where 35 feet is the maximum allowed);
• Reduce the parking requirement to allow 289 spaces (where 299 spaces are
required); and
• Deviate from the parking design standard by reducing the size of 53 parking
spaces to 8’X16’ to allow for compact spaces (where 9’X19’ is required).
The applicant initially proposed placing the hotel building alongside the northwestern
portion of the lot—abutting the Farmer Boys drive-thru restaurant—along with the three-
story office building and a drive-thru restaurant building adjacent to the flood control
channel. The drive-thru restaurant building was eliminated due to the high parking
demand and potential noise impacts to nearby residences, and replaced with a one -
story medical office building requiring less parking and reduced hours of operation.
Staff strongly recommended relocating the hotel and three-story office buildings to the
southern boundary in order to push the buildings as far away from the existing
residences across the flood control channel and alleviate any potential privacy and
shade and shadow concerns from the height of the buildings. The modifications to the
Project allow the buildings to be located closest to the south property line by allocating
7.1.c
Packet Pg. 79
Brea Canyon Business Park Project - Planning Case No. PL2017-169
Page 13 of 27
the floor areas vertically, share parking between the parcels, and utilize the rear portion
of the parking lot with compact stalls. The Planned Development Overlay District allows
for the modifications based on the site design and is deemed to be the best layout due
to the size and configuration of the lot, while being mindful of existing residential uses.
Tentative Parcel Map (DBMC Section 21.20.080)
Pursuant to Section 66424 of the Subdivision Map Act, a Tentative Parcel Map is
required for the subdivision of any units/parcels of improved land for the purpose of
sale, lease or financing. A Tentative Parcel Map is requested to subdivide the lot into
three separate parcels to allow each parcel to be sold off and separately owned and
one parcel to be owned in common ; and to create a condominium subdivision of air
space for two office buildings. A common lot will include the driveway access, internal
circulation system, parking, open spaces, easements and utilities. The three -story
office building will subdivide air space for 34 medical and general office units, and the
one-story medical office building will subdivide air space for two medical office units.
These properties will be governed by a property owners association and a property
maintenance agreement to share the driveway access, parking, utility systems, and
other areas to be owned in common by the association. The office buildings will be sold
as office condominiums, governed by a condominium association.
The proposed subdivision will result in four separate parcels and condominiums as
listed below:
Proposed Parcel Proposed Use Lot Size Condominium
Parcel 1 Three-Story Office 17,237 sq. ft. 34 Units
Parcel 2 One-Story Medical Office 9,642 sq. ft. 2 Units
Parcel 3 Four-Story Hotel 21,982 sq. ft. -
Parcel 4 Common Areas 200,161 sq. ft. -
249,022 sq. ft.
(5.7 acres)
36 Units
The Project is conditioned to submit Covenants, Conditions, and Restrictions (CC&Rs)
that govern the four parcels as well as the condominium units within the office buildings,
and is subject to review and approval by the Planning Division, Public W orks
Department, and City Attorney prior to final map approval.
Development Review (DBMC Section 22.48)
The purpose of Development Review (DR) is to establish consistency with the General
Plan through the promotion of high aesthetic and functional standa rds to complement
and add to the economic, physical, and social character of the City. The process
ensures that new development and intensification of existing development yields a
pleasant living environment, and attracts the interest of residents and visitors as the
result of consistent exemplary design.

**The Planned Development Overlay District allows for modifications to the parking
requirement. Additionally, the proposed Project will provide adequate parking by
means of a shared parking arrangement with the proposed parcels. The conditions
of approval require a reciprocal parking and access agreement to be recorded with
the final map.
The Project is comprised of three buildings and complies with the development
standards in the C-3 zone with the exception of the modifications being requested. The
Planned Development Overlay District allows for the modifications based on the site
design and is deemed to be the best layout due to the size and configuration of the lot.
• Architectural Features, Colors, and Material: The City’s Design Guidelines have
been established to encourage a better compatible build ing and site design that
improves the vital quality of the surrounding area through aesthetically pleasing site
planning, building design, and architecture. In addition, a primary objective is to
promote compatibility with adjacent uses to minimize any potential negative impacts.
Notable elements of the project design which address the Citywide Design
Guidelines include, among other things, the following:
➢ The exterior building design, including roof style, color, materials, architectural
form and detailing is consistent on all elevations of each building to achieve
7.1.c
Packet Pg. 81
Brea Canyon Business Park Project - Planning Case No. PL2017-169
Page 15 of 27
design harmony and continuity within itself. Parapet walls are also treated as an
integral part of the building design.
➢ Monotony of building design as well as busyness is avoided through variation in
wall plane, roof line, detailing and materials.
➢ Articulation and accent colors for identity and visual interest are provided for the
building entrances, and special accents such as decorative interlocking pavers
and specimen trees are used to generate visual interest at entry points.
➢ Elements which transition to the human scale, particularly near the ground, are
integral components of the building designs.
➢ Outdoor open spaces for each building are incorporated within the commercial
center, creating a sense of community gathering places.
➢ Parking areas are screened from the street and adjacent residential properties
with landscaping.
Parking Permit (DBMC Section 22.30.050)
Pursuant to DBMC Section 22.30.050 of the Development Code, where two or more
commercial uses are developed as a professional center and those uses have distinct
and differing peak parking usage periods, a reduction in the required number of parking
spaces may be allowed through the approval of a parking permit, provided that t he most
remote space is located within 300 feet of the use it is intended to serve (as measured
along the most direct pedestrian path). The amount of reduction may be up to the
amount of spaces required for the least intensive of the two or more uses shar ing the
parking. The applicant is requesting a Parking Permit because there is a technical
deficit of 10 parking spaces overall, but all uses will share common parking areas.
Because there is a deficit number of parking spaces when shared parking dynami cs are
not factored in, staff required a parking study to analyze the parking demand through
the application of a shared parking concept. The applicant submitted a parking study
(Attachment E), prepared and signed by a licensed traffic engineer, that prov ides
parking demand calculations based on survey data collected at a similar hotel site in
conjunction with the Urban Land Institute’s Shared Parking (2 nd Edition) methodology.
As stated, there are 289 spaces proposed on-site, of which 53 are compact spaces and
are proposed to be allocated for employee parking. Based on the parking studies
assessing the projected peak weekday parking demand of 261 spaces, there will be a
surplus of 29 spaces; and the peak weekend parking demand totals 178 spaces, which
results in a surplus of 111 spaces. An alternative assessment was done to ensure that
adequate parking is provided using parking utilization data/surveys for the hotel
component with the office uses, resulting in a surplus of 62 spaces on weekdays and
144 spaces on weekends. The proposed development will adequately meet the overall
7.1.c
Packet Pg. 82
Brea Canyon Business Park Project - Planning Case No. PL2017-169
Page 16 of 27
parking demand by providing 289 spaces for all parcels. To ensure that adequate
parking is available for customers and employees of the Brea Canyon Business Center,
a Parking Management Plan will be developed that identifies the proposed employee
parking spaces and key management strategies such as short term/time restricted
spaces to maximize the availability of parking for customers of the center.

The applicant is required to submit a reciprocal parking and access agreement
governing the use and access of all common driveways, parking, and easement areas.
The agreement will be reviewed and approved by the Planning Division and City
Attorney’s Office prior to issuance of building permits.
Traffic Impacts:
Access to the Project site will be provided via a one right -turn in and right-turn out
unsignalized driveway on Brea Canyon Road. A raised landscaped central median will
be constructed along Brea Canyon Road in order to prevent vehicles from turning left to
exit the Project site, as well as those traveling southbound along Brea Canyon Road
from turning left into the Project site. Other traffic improvements include the following:
• Restriping of the northbound approach to westbound Lycoming Street along Brea
Canyon Road to the north of the Project’s driveway to provide an additional
exclusive westbound left-turn lane.
• Restriping of the existing eastbound Lycoming Street shared left/through/right
turn lane to provide an exclusive left-turn lane and shared through/right-turn lane.
7.1.c
Packet Pg. 83

Page 17 of 27
• Restriping of the existing westbound Lycoming Street to accommodate two
receiving lanes due to the addition of a second exclusive westbound left-turn
lane.
The existing roadway condition at the intersection of Brea Canyon Road at Lycoming
Street is currently operating at an acceptable level of service in the AM peak hours
(LOS D) and an unacceptable level of service in the PM peak hours (LOS E). The
proposed Project significantly impacts this intersection of Brea Canyon Road at
Lycoming Street, operating at an unacceptable level of service (LOS E in the AM peak
hours and LOS F in the PM peak hours). However, the implementation of traffic
improvements at the intersection will offset the Project increment and result in an
acceptable level of service in the AM and PM peak hours (LOS D).

Comprehensive Sign Program (DBMC Section 22.36.060)
The Development Code requires a Comprehensive Sign Program (CSP) for multitenant
developments of three or more separate tenants. The intent of a CSP “is to integrate a
project's signs with the design of the structures to achieve a unified architectural
statement. A comprehensive sign program provides a means for the flexible application
of sign regulations for multitenant projects and other users of multiple signs in order to
encourage creativity and provide incentive and latitude in the provision of multiple signs
and to achieve, not circumvent, the intent of (the Sign Ordinance)”
[DBMC Section 22.36.060(a)].
The proposed CSP is included in Attachment F. Detailed conceptual designs for all
signs are included and specified below. The criteria are tailored to ensure that the
proposed signage is appropriate to the Project. The applicant is proposing four wall
signs for each elevation of the hotel building and one wall sign for the one -story office
building. A 10-foot high freestanding monument sign is proposed at the Project entry,
and smaller freestanding monument signs are proposed in front of the office buildings.
The proposed sign criteria require that the proposed signs be reviewed as part of the
design review of the building as to size, sign area, and their proportion to the building.
The following is a detailed description of each proposed sign and the analysis of its
placement and sign area.

The proposed CSP satisfies the purpose and intent of the Development Code by
integrating the signage with the design of the building and having specific size, location,
and design requirements for freestanding and building-mounted signs.
The CSP enhances the overall development by providing size criteria for wall and
monument signs that are appropriate to the scale and setbacks of the buildings, and are
placed so that they respect and harmonize with the architectural elements onto which
they will be mounted or constructed. All text, graphics and logos will be individually
fabricated in accordance with the tenants’ branding specifications, and no generic letter
styles or sign cabinets with interchangeable sign panels will be allowed.
Compatibility with Neighborhood
Community Meeting
The applicant held a community meeting on February 22, 2018. Notices were mailed to
property owners within a 700-foot radius of the Project site. There were approximate ly
30 residents in attendance.
The following concerns and comments were raised at the meeting:
• Traffic Impacts: New development will generate additional traffic in the area;
vehicles will stack up on northbound Brea Canyon Road to make a U -turn on
Lycoming Street since a left turn will not be allowed from the Project site; and
tour buses will use the parking lot or will drop off tourists on Brea Canyon Road
causing more traffic in the area.
• The height of the buildings will create privacy issues such a s views into the rear
yards and bedroom windows of the residential homes to the north.
• The proposed buildings will block sunlight and cast shadows onto the properties
to the north and east.
• There will be additional gas emissions and noise generated from the
development and will affect the children and school across the street.
• The parking lot will be a truck stop.
• The development will attract prostitution and homeless.

The site is primarily surrounded by existing single-family residential development to the
north, east, and west, the 60 freeway to the south, and existing commercial
development to the northwest. The northerly and easterly residential properties are
separated by a 50-foot wide Los Angeles County flood control easement and the
westerly residential properties are separated by Brea Canyon Road.
Aerial View Looking South
Visual Impact: The freeway mainline is located approximately 30 feet higher than the
Project site. With the heights of the hotel and three -story office buildings and the
placement of these buildings along the southern boundary, a portion of the freeway will
be screened from a number of existing homes along the westerly segments of Dryander
Drive and portions of Lycoming Street west of Dryander Drive.
Noise: Although the freeway noise will continue to radiate over and around the hotel
and the three-story office buildings, the proposed buildings will attenuate some of the
existing ambient noise.
Privacy and Visual Screening: Previous site layouts proposed placing the hotel building
alongside the northwestern portion of the lot—abutting the Farmer Boys drive-thru
restaurant—along with the three-story office building adjacent to the flood control
channel. A shade and shadow study was conducted on the previous layout s. The
three-story office building created shadow impacts onto nearby residential properties.
In order to avoid or minimize potential visual intrusion and the proposed buildings
casting shadows on the nearby residential properties and respond to the conc erns
raised at the community meeting, the placement of the hotel and three -story office
7.1.c
Packet Pg. 88
Brea Canyon Business Park Project - Planning Case No. PL2017-169

buildings were relocated to the southern boundary of the lot, away from the nearby
residential homes to avoid such impacts.
At its nearest location, the hotel building will be located approximately 246 feet away
from the nearest single-family home, and the three-story office building will be located
approximately 132 feet away. The windows are inoperable and no exterior walkways or
balconies are provided on either building. The Project is designed to minimize the
negative impacts on the surrounding homes to the north. The perimeter of the site is
appropriately screened with landscaped buffering on all sides. Although the existing
trees located along the north property line, adjacent to the County flood control channel
will be removed, the applicant will be installing a landscaped buffer area with large
36-inch box, double row of large canopy trees to provide screening for the residential
homes on Lycoming Street and Dryander Drive, located directly across the flood control
channel. Section views below illustrate an individual standing on the fourth floor of the
hotel building looking north into the rear yard areas of the homes along Lycoming
Street, as well another section illustrating an individual standing on the third floor of the
three-story office building looking north toward homes along Dryander Drive. Given the
distance and the planting of double row of large canopy trees, the views will be
obstructed.

Shade and Shadow Impacts: Due to the height of the four-story hotel and three-story
office buildings, staff required a shade and shadow study to analyze the shadows cast
onto residential properties to the north. The analysis illustrated that there were no
shadows cast by the proposed Project onto nearby residential properties, with the
exception of three residences located along Dryander Drive. The front yard areas of
two residences and the side yard of one residence appear to have shadows cast in the
month of December, but the roof areas where solar systems could be placed are not
impacted.
An illustration of the worst-case scenario is presented below, during the winter solstice
where the sun is lower in the sky and shadows are at their maximum lengths.
Additionally, the corner property located on Dryander Drive already has shadows cast in
the side yard by existing tall Italian cypress trees located along the south property line.

Project Benefits
The Project will allow for the productive use of an underutilized property, introduces a
land use that will generate local tax revenue (specifically hotel transient occ upancy tax)
and increase property tax revenue for the benefit of the City and its constituents to
provide better support public services and facilities, and provide additional employment
opportunities to the area’s existing labor force, thereby improving the City’s jobs/housing
balance. The Project is also consistent with the City Council’s 2017 -2020 Strategic
Plan, most notably the Safe, Sustainable and Healthy Community goal to “(s)ecure a
development agreement for a new hotel project.”
The neighborhood will also benefit from improvements from this Project, some of which
include:
• Traffic improvements on Brea Canyon Road to improve traffic flow in the area.
• Attractive streetscape improvements along the Project frontage.
• High-quality architecture and significant landscape improvements, including the
planting of 221 new trees (a net increase of 131 trees).
• Streetscape improvements to expand the City’s streetscape beautification program.
• Upgrade the Caltrans offramp with landscaping, and thus enhancing one of the entry
points to the City.
Additional Review
The Public Works/Engineering Department and Building and Safety Division, as well as
the County of Los Angeles Fire Department reviewed this Project and included their
comments in the attached resolutions as conditions of approval.
ENVIRONMENTAL ASSESSMENT:
This Project has been reviewed for compliance with the California Environmental
Quality Act (CEQA). Based on that assessment, the City prepared an Initial Study and
filed a Notice of Intent to Adopt a Mitigated Negative Declaration (MND) for the Project
with the Office of Planning and Research and the Los Angeles County Clerk on
September 19, 2019. The notice was published in the Inland Valley Daily Tribune and
San Gabriel Valley Tribune newspapers (see Exhibit A of Attachment A). The notice
was also mailed to public agencies and residents who attended the community meeting.
Pursuant to CEQA Section 15105, a 30-day public review period for the MND began on
September 20, 2019, and ended October 19, 2019.
The Initial Study is a preliminary analysis to determine whether or not a Negative
Declaration, Mitigated Negative Declaration, or Environmental Impact Report (EIR) is
7.1.c
Packet Pg. 92
Brea Canyon Business Park Project - Planning Case No. PL2017-169
Page 26 of 27
needed for a project. If the Initial Study concludes that the proposed Project will not
significantly affect the environment, a Negative Declaration may be prepared. If there
are potential impacts from the proposed Project that can be mitigated to a level of less
than significant, a Mitigated Negative Declaration may be prepared. The Initial Study
concluded that the Project will not significantly affect the environment through the
incorporation of 22 mitigation measures, and as the result of previous revisions to the
proposed Project which were agreed to by the applicant to mitigate other potential
impacts.
An MND is a written document that describes the reasons that the Project will not have
a significant effect on the environment by properly conditioning the Project (“mitigation
measures”) to make the Project acceptable. It is used to guide and assist the City staff,
Planning Commission, City Council, and the public in the consideration and evaluation
of potential environmental impacts that may result from the Project and must be
considered by the Commission prior to recommending approval of the Project.
The MND for the Project, documents reasons to support the findings that the Project
would not have any potentially significant impacts on the environment with the proposed
mitigation measures which are contained with the Mitigation Reporting and Monitoring
Program (MRMP) prepared as part of the MND. The purpose of the MRMP is to ensure
compliance with the mitigation measures, address site-specific conditions for the
Project, and also identifies timing and responsibility fo r monitoring each measure and is
attached to the Resolution recommending adoption of the MND (Exhibit B of Attachment
A). The Project is conditioned to include these mitigation measures as part of Project
approval.
Cultural Resources
Senate Bill 18 and Assembly Bill 52 – Tribal Consultation: SB18 and AB52 requires
notification/request for tribal consultation for projects. SB18 applies when amending a
general plan land use designation, and AB52 applies to projects subject to CEQA. A
notification list was obtained from the Native American Heritage Commission and the
City sent notices to the Tribes informing them of the opportunity to request consultation
on July 24, 2019. On July 30, 2019, the City received a letter from the Gabrieleño Band
of Mission Indians (Kizh Nation), indicating that the Project area lies in an area where
the ancestral territories of the Kizh (Kitc) Gabrieleño villages adjoined and overlapped.
On August 5, 2019, the City also received a letter from the Gabrielino -Tongva Tribe
indicating ancestral ties and cultural affiliation to the Project area. In accordance with
the request by the tribes, a mitigation measure was added requiring the applicant to
retain a culturally-affiliated Native American monitor to observe earthmoving activities
for the purpose of identifying the potential presence of any significant historic or
prehistoric cultural resources.
NOTICE OF PUBLIC HEARING:
Public hearing notices were mailed to property owners within a 700 -foot radius of the
Project site on October 17, 2019, and to the residents who attended the community

meeting. The notice was also published in the Inland Valley Daily Tribune and San
Gabriel Valley Tribune newspapers on October 18, 2019. The Project site was posted
with a notice display board, and a copy of the public notice was posted at the City’s four
designated community posting sites.

Mitigated Negative Declaration April 2022
Addendum Page 1
1.1 Introduction
Summary
The City previously approved an application to develop the project known as the “Brea Canyon
Business Park” (BCBP). The previously approved project called for a 109-room, four-story, hotel,
a 47,642 gross square-foot, three-story, office building, and an 8,900 gross square-foot, single-
story, medical office building on a 5.7-acre vacant parcel located on the east side of south Brea
Canyon Road between Lycoming Street and the Pomona (SR-60) freeway. The potential
environmental impacts of that project were analyzed in an “Initial Study” and a “Mitigated Negative
Declaration” (MND) was prepared. On November 19, 2019, the MND was adopted and the
development application was approved. A “Notice of Determination” was filed and posted on
November 20, 2019. No California Environmental Quality Act (CEQA) challenge was filed.
Lycoming, LLC (Applicant) has now proposed revisions to the previously approved project.
Generally, these changes call for:
The replacement of the 8,900 gross square-foot, single-story, medical building with a 6,500
gross square-foot, single-story, commercial building to accommodate a drive-through
restaurant and up to two (2) future retail or fast-food tenants;
An outdoor dining area for the “retail/restaurant” building;
The addition of 15 hotel rooms (for a new total of 124 hotel rooms);
The addition of southbound left-turn pocket on Brea Canyon Road to accommodate a left
turn-in access to the project; and
The refurbishment of an existing 65-foot pylon sign.
Pursuant to Section 21166 of the Public Resources Code (PRC) and Section 15162 of the State
Guidelines for the California Environmental Quality Act (State CEQA Guidelines), the City
analyzed whether those revisions would result in new significant impacts or a substantial increase
in severity of previously identified impacts. Based on the City’s analysis, no subsequent EIR,
supplemental EIR, or subsequent mitigated negative declaration is required. As a result, the
City’s analysis and conclusions are documented in this “Addendum” (Section 15164, State CEQA
Guidelines).
2019 Approved BCBP/MND
On December 4, 2017, the Applicant, representing the property owner (Brea Canyon Co, LLC) of
an approximately 5.73-acre (249,022 gross square feet) site (850 S. Brea Canyon Road, Diamond
Bar, California 91789), submitted a development application for a 117,500 gross square-foot
(GSF),1 3-building, private development project, including retail/fast food, hotel, medical and
general office uses (2017 Development Application), in the City. Filing fees were collected by the
City of Diamond Bar (City or Lead Agency) on December 6, 2017). Upon receipt, discussions
concerning the then proposed project commenced with City staff.
In response, on August 20, 2019, the Applicant submitted an updated development application
comprised of three buildings, including a 4-story hotel, a 3-story medical/general office building,
1/ Except where explicitly noted, the terms “gross square feet” (GSF) and “square feet” (SF) are used
interchangeably herein.

and a one-story medical office building, totaling 118,471 GSF. Absent therefrom was any retail
commercial and/or restaurant-related land uses.
The Applicant’s August 20, 2019 development application (2019 Development Application)
identified the proposed development as the “Brea Canyon Business Park” (BCBP) and included
requests for a number of City-issued discretionary actions, including, but not limited to, an
amendment to the City’s existing general plan (GPA), zone change (ZC), “tentative” parcel map,
conditional use permit (CUP), “shared-parking” permit, and comprehensive sign program. Under
the provisions of the California Environmental Quality Act (CEQA)2 and the Guidelines for the
Implementation of the California Environmental Quality Act 3 (State CEQA Guidelines), the City
subsequently deemed the 2019 Development Application “complete” and formally initiated a
detailed environmental analysis thereof.
On November 19, 2019, following the culmination of that environmental review process, including
the conclusion of Native American consultation, the City of Diamond Bar City Council (Council)
conditionally approved the BCBP (Planning Case No. 2017-169) (2019 Approved BCBP),4
authorizing the construction and operation of a 118,471 GSF private development project
consisting of a “hotel,” “medical office,” and “general office” uses. Additional off-site project
components included, but were not limited to, improvements to Brea Canyon Road and to the
Brea Canyon Road/Lycoming Street intersection and landscape improvements within the
Pomona (SR-60) Freeway right-of-way (ROW), as administered by the California Department of
Transportation (Caltrans).
Reference to the 2019 Approved BCBP herein is inclusive of the then proposed uses of the project
site and those off-site areas associated therewith, the approval, construction, and occupancy of
those uses, all activities associated therewith, all discretionary and ministerial entitlements
relating thereto, and those “mitigation measures” and “conditions of approval” adopted by the
Council and associated therewith or imposed thereupon. As part of that action, the City adopted
the following implementing resolutions and ordinance:
Resolution No. 2019-40 - A Resolution of the City Council of the City of Diamond Bar,
California Approving the Mitigated Negative Declaration and Adopting the Mitigation
Reporting and Monitoring Program for the Brea Canyon Business Park Project Located at

Brea Canyon Road (Assessors Parcel No. 8719-013-017).
Resolution No. 2019-42 - A Resolution of the City Council of the City of Diamond Bar,
California Approving the Brea Canyon Business Park Project No. PL2017-169 Consisting of
2/ Sections 21000-21177 of the Public Resources Code (PRC).
3/ Sections 15000-15387 in Title 14, Chapter 3 of the California Code of Regulations (CCR).
4/ Referencing Section 15352 of the State CEQA Guidelines: “(a) ‘Approval’ means the decision by a public
agency which commits the agency to a definite course of action in regard to a project intended to be carried out by any
person. The exact date of approval of any project is a matter determined by each public agency according to its rules,
regulations, and ordinances. Legislative action in regard to a project often constitutes approval. (b) With private projects,
approval occurs upon the earliest commitment to issue or the issuance by the public agency of a discretionary contract,
grant, subsidy, loan, or other form of financial assistance, lease, permit, license, certificate, or other entitlement for use
of the project.”

On November 19, 2019, prior to taking any formal action on the 2019 Approved BCBP, following
noticed public hearings and requisite Native American consultation, the Council adopted the MND
for the project via Resolution No. 2019-40 (A Resolution of the City Council of the City of Diamond
Bar, California Approving the Mitigated Negative Declaration and Adopting the Mitigation
Reporting and Monitoring Program for the Brea Canyon Business Park Project Located at 850 S.
Brea Canyon Road, Diamond Bar, California Associated with Planning Case No. PL2017-169
[Assessors Parcel Number 8719-013-017]). Resolution No. 2019-40 included “approving the
“Mitigated Negative Declaration and adopting the mitigation reporting and monitoring program for
the Brea Canyon Business Park Project located at 850 S. Brea Canyon Road, Diamond Bar,
California.”5
Reference to the 2019 Approved BCBP/MND herein is inclusive of the accompanying “Initial
Study,” “Environmental Checklist Form,” and “Mitigated Negative Declaration for the Brea Canyon
Business Park: 859 Brea Canyon Road, Diamond Bar, California – Mitigation Reporting and
Monitoring Program” (November 19, 2019) (2019 Approved BCBP/MND/MRMP), including all
related documents, notices, correspondence, communiques, and public hearings associated
therewith. As adopted by the Council, the 2019 Approved BCBP/MND/MRMP imposed specific
mitigation measures on the 2019 Approved BCBP. In addition, although not identified as CEQA-
mandated actions, the Council also imposed numerous “conditions of approval” and other
“exactions” on the 2019 Approved BCBP.
In the interim between the filing of the 2019 Development Application (August 20, 2019) and the
approval of the 2019 Approved BCBP (November 19, 2019), all business operations, including
boat and recreational vehicle (RV) storage activities, previously being conducted on the project
site were terminated, all boats and recreational vehicles removed, and all above-ground
improvements were demolished. Since that time, the project site has remained vacant.
5/ The project described in Resolution No. 2019-42 consisted of a “109-room, four-story hotel, a 47,642 square
foot, three-story office building; and an 8,900 square-foot, one level medical office building.” Because the gross square
footage of the “109-room, four-story hotel” was not explicitly stated therein, the total gross square footage of the 2019
Approved BCBP was not identified in Resolution No. 2019-42.
The 2019 Approved BCBP/MND evaluated a project totaling 118,471 gross square feet within the following stand-
alone structures: “(1) a 47,828 square-foot general and medical office building (Lot 1 [Parcel 1], Tentative Parcel Map
No. [TPM] 82066); (2) an 8,900 square-foot medical office building (Lot 2 [Parcel 2], TPM 82066); and (3) a 61,743
square-foot, 109-room hotel (Lot 3 [Parcel 3], TPM 82066).”
Based on the evolving nature of architectural and engineering plans, a minor difference between the project
described in the 2019 Approved BCBP/MND and the project depicted in the Resolution No. 2019-42 existed. Any
identified differences between those two documents have been deemed by the Department to be de minimis and not
consequential relative to the potential environmental impacts attributable to the 2019 Approved BCBP and the
adequacy of the 2019 Approved BCBP/MND.

2021 Proposed Revised BCBP
Constituting actions beyond the Applicant’s and the City’s control, the occurrence of COVID-19
widely affected southern California and resulted in numerous societal and economic public and
private impacts attributable thereto.6 Despite specific good-faith declarations by the Applicant, as
presented in the 2019 Approved BCBP/MND, with the exception of rough grading activities, the
initiation of construction of the 2019 Approved BCBP has not proceeded in the manner and in the
timeframe outlined therein.
As time has passed, the Applicant reassessed the evolving nature of the local and regional real
estate marketplace on the range and configuration of uses that the Applicant has elected to
implement on the project site. The Applicant has acknowledged that the presence of the “novel
coronavirus” (COVID-19), whose existence first manifested after the City’s approval of the 2019
Approved BCBP, has played a critical part in that reassessment process. The Community
Development Department (Department) acknowledges that the COVID-19 pandemic has had and
is expected to have a continuing material adverse social and economic impact on a broad
spectrum of society, including the real estate marketplace, for an indeterminate length of time.7
In response to changing market conditions, on May 20, 2021, the Applicant submitted a “revised”
development application (2021 Development Application) requesting modifications to the
previously approved project and its corresponding entitlements (2021 Proposed Revised BCBP).
Specifically, the 2021 Development Application seeks approval of a “revised” development
concept, introducing additional on-site land uses (i.e., retail commercial and restaurant-related
uses) that were not previously contemplated in the 2019 Approved BCBP/MND, altering the
approved “tentative” subdivision map and site plan, removing certain access restrictions thereto,
and corresponding entitlements. These revisions generally include:
The replacement of the 8,900 gross square-foot, single-story, medical building with a 6,500
gross square-foot, single-story, commercial building to accommodate a drive-through
restaurant and up to two (2) future retail or fast-food tenants;
An outdoor dining area for the “retail/restaurant” building;
The addition of 15 hotel rooms (for a new total of 124 hotel rooms);
Hotel modification include extending the front by about two feet in certain areas;
The addition of southbound left-turn pocket on Brea Canyon Road to accommodate a left
turn-in access to the project; and
The refurbishment of an existing 65-foot pylon sign.
The corresponding requested entitlements include:
Amendment to Tentative Parcel Map to eliminate the condominium subdivision for the
single-story 8,900 gross square-foot medical office building and replace with a single-story
6,500 gross square-foot commercial building to accommodate a drive-thru restaurant and
up to two future retail or fast-food restaurant tenants.
Amendment to Development Review to approve the revisions to the site and architectural
design of a new commercial development to ensure consistency with the “City of Diamond

July 29, 2021, there have been 34,473,788 confirmed cases of COVID-19 and 606,686 deaths directly linked thereto
(https://covid19.who.int/region/amro/country/us).

Bar General Plan,” “Diamond Bar Municipal Code” (DBMC), and compliance with all
applicable design guidelines and standards. The proposed amendments include the
replacement of the above-referenced 8,900 gross square-foot medical office building with a
6,500 gross square-foot commercial building with drive-thru lane, addition of 15 hotel rooms
(approved for 109 rooms and proposing 124 rooms), and the addition of a southbound left-
turn pocket on Brea Canyon Road to accommodate a left turn in access to the
project. Additionally, there are no major exterior changes to the four-story hotel building.
Amendment to Conditional Use Permit to approve a drive-thru service for the proposed
fast-food restaurant at the 6,500 gross square-foot commercial building.
Amendment to Parking Permit to approve the updates to the shared-parking demand
analysis.
Amendment to Comprehensive Sign Program to approve the refurbishment of an existing
65-foot tall pylon sign, addition of a wall sign on the three-story medical office building; and
associated wall signs on the proposed one-story commercial building.
Minor Conditional Use Permit to approve the outdoor dining area for the single-story 6,500
gross square-foot commercial building.
In order distinguish between the 2019 Approved BCBP (including its accompanying 2019
Approved BCBP/MND and the 2019 Development Application), the current development concept
described herein is identified as the 2021 Proposed Revised BCBP (including its accompanying
2021 Proposed Revised BCBP/Addendum and the 2021 Development Application).
1.2 California Environmental Quality Act
The 2021 Development Application constitutes a proposal for a “private project,” defined as a
“project which will be carried out by a person other than a governmental agency, but the project
will need a discretionary approval from one or more governmental agencies for: (a) A contract or
financial assistance, or (b) A lease, permit, license, certificate, or other entitlement for use”
(Section 15377, State CEQA Guidelines). Pursuant thereto, the City has: (1) encouraged the
Applicant to incorporate environmental considerations into project conceptualization, design, and
planning at the earliest feasible time (Section 15004[b][3], State CEQA Guidelines); and (2)
consulted with the Applicant to determine if the applicant is willing to modify the project to reduce
or avoid the significant effects (Section 15063[g], State CEQA Guidelines.
Pursuant to Section 15358 of the State CEQA Guidelines: “Effects analyzed under CEQA must
be related to a physical change.” CEQA defines a “project,” in part, to constitute “the whole of an
action, which has a potential for resulting in either a direct physical change in the environment, or
a reasonably foreseeable indirect physical change in the environment” (Section 21065, CEQA;
Section 15378, State CEQA Guidelines).
Rough grading activities associated with the implementation of the 2019 Approved BCBP have
already commenced under the authority of City-issued permits (December 7, 2020) and pursuant
to those conditions of approval associated therewith.
When evaluating a proposed change to a project that has previously been reviewed under CEQA,
the lead agency must apply CEQA’s standards limiting the scope of subsequent environmental
review. Under these standards, once an environmental impact report (EIR) has been certified or
7.1.d
Packet Pg. 111
Brea Canyon Business Park Project
850 S. Brea Canyon Road, Diamond Bar, California 91789
April 2022 Mitigated Negative Declaration
Page 6 Addendum
a negative declaration adopted for a project, further CEQA review is limited. These standards
apply whether or not the project has been constructed.
Section 21166 of the PRC states:
When an environmental impact report has been prepared for a project pursuant to this
division, no subsequent or supplemental environmental impact report shall be required
by the lead agency or by any responsible agency, unless one or more of the following
events occurs:
(a) Substantial changes are proposed in the project which will require major revisions
of the environmental impact report.
(b) Substantial changes occur with respect to the circumstances under which the
project is being undertaken which will require major revisions in the environmental
impact report.
(c) New information, which was not known and could not have been known at the time
the environmental impact report was certified as complete, becomes available.
As specified in Section 15162(a) and (b) of the State CEQA Guidelines:
(a) When an EIR has been certified or a negative declaration adopted for a project, no
subsequent EIR shall be prepared for that project unless the lead agency
determines, on the basis of substantial evidence in the light of the whole record,
one or more of the following:
(1) Substantial changes are proposed in the project which will require major
revisions of the previous EIR or negative declaration due to the involvement
of new significant environmental effects or a substantial increase in the
severity of previously identified significant effects;
(2) Substantial changes occur with respect to the circumstances under which the
project is undertaken which will require major revisions of the previous EIR or
negative declaration due to the involvement of new significant environmental
effects or a substantial increase in the severity of previously identified
significant effects; or
(3) New information of substantial importance, which was not known and could
not have been known with the exercise of reasonable diligence at the time the
previous EIR was certified as complete or the negative declaration was
adopted, shows any of the following:
(A) The project will have one or more significant effects not discussed in the
previous EIR or negative declaration;
(B) Significant effects previously examined will be substantially more severe
than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible
would in fact be feasible, and would substantially reduce one or more
significant effects of the project, but the project proponents decline to
adopt the mitigation measure or alternative; or
(D) Mitigation measures or alternatives which are considerably different from
those analyzed in the previous EIR would substantially reduce one or
more significant effects on the environment, but the project proponents
decline to adopt the mitigation measure or alternative.

Addendum Page 7
(b) If changes to a project or its circumstances occur or new information becomes
available after adoption of a negative declaration, the lead agency shall
prepare a subsequent EIR if required under subdivision (a). Otherwise the
lead agency shall determine whether to prepare a subsequent negative
declaration, an addendum, or no further documentation.
As specified, in relevant part, in Section 15164 of the State CEQA Guidelines:
“An addendum to an adopted negative declaration may be prepared if only minor technical
changes or additions are necessary or none of the conditions described in Section 15162
calling for the preparation of a subsequent EIR or negative declaration have occurred”
(Section 15164[b], State CEQA Guidelines);
“An addendum need not be circulated for public review but can be included in or attached to
the final EIR [environmental impact report] or adopted negative declaration” (Section
15164[c], State CEQA Guidelines); and
“The decision making body shall consider the addendum with the final EIR or adopted
negative declaration prior to making a decision on the project” (Section 15164[d], State
CEQA Guidelines).
An “addendum” to a negative declaration, mitigated negative declaration, or EIR is only authorized
when: (1) the proposed action constitutes a “project” under CEQA (Section 15378, State CEQA
Guidelines); and (2) when only minor changes to an approved project are being proposed (Section
15162[a], State CEQA Guidelines).
As set forth in detail below, pursuant to Section 21166 of the PRC and Section 15162 of the State
CEQA Guidelines, the City analyzed whether the revisions requested in the 2021 Proposed
Revised BCBP would result in new significant impacts or a substantial increase in severity of
previously identified impacts. Based on the City’s analysis, no subsequent EIR, supplemental
EIR, or subsequent mitigated negative declaration is required. As a result, the City’s analysis and
conclusions are documented in this Addendum (Section 15164, State CEQA Guidelines).
It should be noted that nothing herein constitutes a predetermination by the Department or by the
Lead Agency’s advisory and decision-making bodies with regards to the approval, conditional
approval, or denial of the 2021 Proposed Revised BCBP or any portion thereof or to the
appropriate manner of CEQA compliance. The preliminary information, analyses, and
recommendations presented herein remain subject to change based on the Department’s further
consideration of the 2021 Proposed Revised BCBP, comments received from the general public
and from other responsible agencies in response thereto, the recommendations of the
Commission, and the independent determination of the Council.
Construction
As indicated in the 2019 Approved BCBP/MND, construction of the 2019 Approved BCBP was
projected to commence on October 1, 2019 and, following the SCAQMD’s California Emissions
Estimator Model’s (CalEEMod) default construction schedule, was estimated to require 320 actual
construction days (excluding weekends) and be completed on December 21, 2020. By delaying

mitigation measures associated therewith. The environmental effects of those activities were
addressed in the 2019 Approved BCBP/MND and fully mitigated based on those mitigation
measures identified in the 2019 Approved BCBP/MND/MRMP (Resolution No. 2019-40,
November 19, 2019). Minor changes to the City-issued grading permit would be required to
accommodate the 2021 Proposed Revised BCBP.
Outside the Applicant’s control, non-project-specific supply chain problems, affecting the entire
southern California region and potentially delaying the delivery of construction materials, could
add additional unexpected delays to various aspects of the construction process.
Assuming that construction continues in 2022, the air quality and GHG assumptions and modeling
continues to remain applicable although the actual construction dates may have changed. If
construction were to continue into 2023, based on increased efficiencies in mechanized
equipment, the presence of more fuel-efficient vehicles, and tightening air quality regulations,
projected construction emissions would be anticipated to be less than the “worst-case” analysis
assumed therein.
Operations
The proposed project modifications in the 2021 Proposed Revised BCBP are:
The replacement of the 8,900 GSF, single-story, medical building with a 6,500 GSF, single-
story, commercial building to accommodate a drive-thru restaurant and up to two (2) future
retail or fast-food tenants;
An outdoor dining area for the retail/restaurant pad;
The total gross square footage of the proposed “hotel” has been increased in size by
approximately 2,785 GSF and the number of guest rooms has increased from 109 to 124
rooms.
The addition of southbound left-turn pocket on Brea Canyon Road to accommodate a left
turn-in access to the project; and
The refurbishment of an existing 65-foot pylon sign.
The total gross leasable square footage of the entire project has increased by an estimated 385
gross square feet from 118,471 to 118,856 GSF.8 With regards to the 2021 Proposed Revised
BCBP, the proposed “medical office” (“Parcel 1”), “retail/restaurant” (“QSR-1) buildings (“Parcel
2”), and “hotel” (“H-1”) (“Parcel 3”), are separately addressed below:
Medical Office. Although “general office” uses would continue to be authorized therein, the
Applicant has requested that the Department examine the proposed “office” (“O-1”) building
(“Parcel 1”) as if to be totally occupied for “medical office” use. As a result, from a trip
8/ As an additional consideration for CEQA purposes, the 2019 Approved BCBP identified the 3-story mixed
“medical office” and general office” building (located on “Parcel 1”) as containing a total of 47,828 GSF (inclusive of all
floors and all uses). In contrast, in Resolution Nos. 2019-40 and 2019-42, the Council described that same building as
containing 47,642 GSF or approximately 186 GSF less than assumed in the 2019 Approved BCBP/MND. For CEQA
purposes, this means that the 2019 MND analyzed a larger footprint than was necessary, and therefore, analyzed more
potential impacts than was necessary. This analysis of the 2021 Proposed Revised BCBP also uses the larger square
footage (47,828 GSF) for consistency purposes.

generation perspective, the higher “medical-dental office building” (LUC 9 720) rate of 34.80
trips/1,000 SF rather than the lower “general office building” (LUC 710) rate of 9.74
trips/1,000 SF has been applied to the gross square footage therein.10
Other than as it relates to tenancy and associated changes to DBMC-specified parking
requirements, no deviations relative to the 2019 Approved BCBP/MND are proposed with
regards to the operation of the multitenant “medical office” (“O-1”) building (“Parcel 1”)
associated with the 2021 Proposed Revised BCBP.
Retail/Restaurant. Represented as a “build-to-suit” project component, because neither the
owner, operator, franchisee, licensee, and/or master leasee of the proposed 6,500 GSF
“retail/restaurant” (“QSR-1”) building (“Parcel 2”) nor the number of “fast-food restaurants”
(with “drive-thru”) and other unspecified “restaurants” been definitively identified by the
Applicant, little, if any, operational information concerning the 2,500 GSF “fast-food
restaurant” (with “drive-thru”), including an accompanying proposed minimum 260 SF
“outdoor dining area,” and 4,000 GSF “restaurant” is known or presently knowable to the
Department. The uses operating within the “retail/restaurant” (“QAR-1”) building (“Parcel 2”)
shall be regulated by the applicable provisions of the DBMC and the City’s permit process.
Hotel. The Applicant has indicated that the proposed 64,528 GSF, 124-room “hotel” would
be a Hilton HamptonTM brand.11,12 However, none of the existing (2019 Approved BCBP) or
proposed (2021 Proposed Revised BCBP) entitlements explicitly specify or are dependent
on either the precise franchise or the Smith Travel Research’s (STR) or other hotel brand,
franchise, or operator (franchisee) chain-scale categorization.13 Except as it may relate to
the revised comprehensive signage program, it is not anticipated that any associated City-
issued entitlements associated with the 2021 Proposed Revised BCBP would restrict the
“hotel” (“H-1”) building (“Parcel 3”) to any specific brand, franchise, or operator.
The proposed “Hilton/HamptonTM is subject to the specifications outlined in the
corporation’s most recent design template,14 representing the requirements established for
design of a Hilton-franchised hotel. That design template is unique to Hilton-franchised
properties. As a result, neither the entitlement nor CEQA processes guarantees that the
proposed hotel will retain its STR chain-scale category rating, its brand affiliation, or preclude
any future operator’s request for subsequent design-related changes thereto over time.

A comparative description of the 2019 Approved BCBP and the 2021 Proposed Revised BCBP
is presented in Table A-1 (Comparative Development Analysis – 2019 Approved BCBP and 2021
Proposed Revised BCBP [September 8, 2021]) herein. This comparison identifies, without
limitation, the following issues:
By changing the proposed land use on “Parcel 2” from “general office” to “retail/restaurant,”
the anticipated hours of operation associated therewith would be expanded to include
additional evening and weekend hours.
Unless specified by the Applicant or subsequently conditioned by the City, without limitation,
one or more “retail/restaurant” businesses physically operating from the proposed
“retail/restaurant” (“QSR”) building (“Parcel 2”), including the operation of the proposed
“drive-thru” aisle, “walk-up window,” and “outdoor dining area,” are assumed as a reasonable
worst-case scenario to operate 24-hours per day and 365 days per year.
♦ Compared to the 2019 Approved BCBP’s “medical office” building (“Parcel 2”), as
associated with the proposed “retail/restaurant” uses, implementation of the 2021
Proposed Revised BCBP would increase exterior lighting and the number and size of
external signage.
♦ The proposed “retail/restaurant” uses (“Parcel 2”) includes the introduction and
operation of outdoor speakers associated with the “drive-thru” restaurant and/or
outdoor dining area. Noise associated with vehicles queuing in the area of the proposed
“drive-thru” aisle is absent from the 2019 Approved BCBP.
♦ The construction of a “drive-thru” aisle adjacent to the project site’s northern boundary
will be expected to increase the number and frequency of motor vehicles idling in
relatively close proximity to existing residential receptors.
♦ The inclusion of outdoor dining opportunities will likely result in a greater number and/or
frequency of people congregating in exterior areas on the project site, including those
present during evening hours and weekend periods.
♦ “Restaurant” uses typically generate odors associated with food preparation and waste
disposal. Those odors are not generally associated with “office” uses.
♦ With regards to the proposed “retail/restaurant” uses, the disposal of organic / green /
food wastes and food-soiled paper could increase the potential for attracting vectors 15
(e.g., rats, mice, and flies) and other food scavengers (e.g., crows and sea gulls)
beyond that which would be typically associated with “office” uses.
♦ Unless effectively operated, “fast-food” restaurants can become a source of litter.
Adopted/Revised/Proposed Mitigation Measures
The City reviewed the mitigation measures imposed on the 2019 Approved BCBP for applicability
to the 2021 Proposed Revised BCP. As indicated in Table A-2 (2021 Proposed Revised BCBP –
Adopted/Revised/Proposed Mitigation Measures), a number of minor changes are proposed
thereto for clarification purposes.16
15/ “Vectors” are defined by the California Department of Public Health as “any insect or other arthropod, rodent
or other animal of public health significance capable of harboring or transmitting the causative agents of human disease,
or capable of causing human discomfort and injury.”
16/ The proposed Department-identified changes to “MM-12” (Geology and Soils) and “MM-21” (Operational
Noise) relate to the City’s adoption of the “California Building Standards Code, 2019 Edition” (2019 CBC) and “California
Green Building Standards Code, 2019 Edition” (2019 CalGreen) on December 3, 2019 (Ordinance No. 04[2019]16), as
amended, and are intended to: (1) obligate the 2021 Proposed Revised BCBP to the most recent set of applicable
standard codes; and (2) delete any explicit language and/or inferences suggesting the City’s willing to rely upon
outdated and superseded code.

Notes: NA – Not Available; NC – No Change 1. Under CEQA, focusing exclusively on a quantitative comparison between approved and proposed project component does not capture the totality of the proposed action and the potential environmental effects associated therewith. Not addressed herein are the Applicant-proposed physical changes to: (1) the fundamental nature of approved and proposed on-site land uses, including those operational changes relating thereto and associated therewith; (2) the project’s ingress/egress, including associated turning movements to and from Brea Canyon Road; (3) off-site changes to the proposed central median located along Brea Canyon Road; (4) proposed improvements to the Brea Canyon Road/Lycoming intersection (including associated fair-share fees); and (5) internal circulation patterns and parking demands.
2.

The number of non-residential “condominium units” is not necessarily indicative of the number of owners, leasees, and/or subleasees that may own, possess, or operate therein. It is assumed that the recorded “conditions, covenants, and approvals” (CC&Rs) and/or other recorded instrument will include a prohibition that any of the non-residential “condominium units” will be used for residential or mixed residential/non-residential purposes.

Notes (Continued): 4. No distinction is made herein relative to any spatial differences between gross square feet (GSF) and gross leasable area (GLA). 5. Square footages are as represented in the 2019 Approved BCBP MND and may differ from that identified in Resolution No. 2019-40 and 42. 6. Without further specification or categorization, identified only as “office” on the “Proposed Revised TPM 82066” (September 8, 2021). 7. As indicated in correspondence from EXDEV, dated July 12, 2021, the following description is provided by the Applicant: “Three-Story Professional Office building with subdivision of air space for 34 medical and general office units. 1st Floor, 2nd Floor, 3rd Floor to allow 100% medical use, with general office still allowed.” 8. The terms “medical” and “office” are presented as broad terms and are not expressly defined as distinct uses in the DBMC. Section 22.80.020 (Definitions of Specialized Terms and Phrases) includes the following categorization of office-related uses: “administrative/business”; “production”; “professional”; “temporary”; and “temporary real estate.” Additionally, the following definitions of “medical services” are provided therein:
“clinics and laboratories”; “extended care”; and “hospitals.” 9. A “food service facility” tenant (e.g., lunch room, cafeteria, and/or convenience store), catering to other tenants and to those members of the general public accessing the project site, would not be not prohibited. 10. Identified by the Applicant as a “speculative” building, to be constructed by the Applicant with no future buyers, tenants, or other site users presently known or explicitly identified. 11. With regards to the 2019 Approved BCBP, the 3-story “office” building proposed on “Parcel 1” was identified in Resolution Nos. 2019-40 and 2019-42 as totaling 47,642-gross-square feet (GSF) (including 31,998 GSF of “office” and 15,644 GSF of “medical office”) and not the 47,828 GSF (including 31,855 GSF of “office” and 15,942 GSF of “medical office”) identified in the 2019 Approved BCBP/MND. Because the total building size assumptions presented in the 2019 Approved BCBP/MND exceeded those presented in Resolution Nos. 2019-40 and 2019-42, the CEQA process accompanying the 2019 Approved BCBP remains applicable thereto and, for CEQA compliance purposes associated with the 2021 Proposed Revised BCBP, although the Applicant’s current development concept identifies only an approximately 47,642 GSF “medical office” structure on “Parcel 1,” the 47,828 GSF figure presented in the 2019 Approved BCBP/MND has been retained herein because that larger square footage represents the factual basis upon which the 2019 Approved BCBP/MND’s and this 2021 Proposed Revised BCBP/Addendum’s environmental impact analyses was and has been derived. 12. The Applicant is not requesting that that the City rescind those prior entitlements associated with the 2019 Approved BCBP, including those associated with the 8,900 GSF multitenant “medical office” building; rather, the Applicant seeks the City’s authorization so as to: (1) retain those prior approvals so as to allow the construction and operation thereof; (2) issue new, revised, amended, updated, expanded, and/or modified entitlements, including associated design and development standards, as may be required for the approval, construction, and operation of the 2021 Proposed Revised BCBP; and (3) concurrently grant the Applicant the authorization to proceed with the development of the 2019 Approved BCBP (e.g., 8,900 GSF multitenant “medical office”) or the 2021 Proposed Revised BCBP (e.g., 6,500 GSF multitenant “retail/restaurant” [“QSR-1”] building), or portions thereof, as an alternative thereto. 13. Identified by the Applicant as a “built-to-suit” project component, to be constructed by the Applicant or by others once the future buyer(s), tenant(s), and/or site user(s) has been identified and in accordance with the specific design standards (template) of that buyer(s), tenant(s), and/or site user(s). 14. Subject to change and refinement. In the same manner as the proposed “hotel use” represents the Hilton HamptonTM specified design template, the Applicant is awaiting receipt of an executed real estate contract with one or more future buyer(s) and will then, based on that agreement and/or the purchaser’s or leaseholder’s precise design requirements, subsequently “build to suit,” potentially altering the site plan, configuration, and design specifications represented in the 2021 Development Application. 15. Including one or more “accessory retail” uses. 16. As specified in Section 22.16.070(1) of the DBMB: “Multitenant commercial centers one acre in size and larger shall provide a minimum of 0.01 percent of the total land area of the center as useable pedestrian-oriented open space, including plazas, patios, courtyards, and outdoor seating areas. The total land area of the center shall include all parcels that comprise the center including freestanding structures on
separate parcels. Project proponents are encouraged to provide open space areas that exceed the minimum amount required.” In compliance therewith, based on an approximately 5.73-acre (249,022 square feet) project site, an estimated minimum 2,490 square feet of pedestrian-oriented open space (e.g., plazas, patios, courtyards, and outdoor seating areas), conforming to the standards outlined in Section 22.16.070(2), is required in compliance therewith. 17. Subject to a “shared-parking” permit.

Cultural Resources. Prior to the issuance of a grading permit, a qualified archaeologist, meeting the Secretary of the Interior’s Standards and Guidelines for Archaeology and Historic Preservation (48 FR 44716, National Parks Service, September 29, 1983) shall be retained by the Applicant to oversee the monitoring of initial ground disturbing activities, including all trenching and excavation activities occurring to a depth greater than three feet below surface grades. The archeologist shall conduct excavation monitoring activities for the purpose of identifying the potential presence of any significant historic or prehistoric cultural resources located within the project boundaries. Delete / No Longer Applicable. With the City’s issuance of a rough grading permit associated with the 2019 Approved BCBP, this project-level mitigation measure was effectively implemented and no longer remains applicable to the 2021 Proposed Revised
BCBP. No further compliance therewith is, therefore, deemed by the Department to be required.
MM-9
Cultural Resources. If cultural resources are identified during monitoring of the ground disturbing activities, the supervising archaeologist shall be empowered to temporarily halt construction in the vicinity of any such discovery while its significance is being evaluated. All cultural resources that may be so recovered will be documented on California Department of Parks and Recreation Site Forms and filed with the California Historical Resources Information System South Central Coastal Information Center at the California State University, Fullerton (CHRIS-SCCIC). Independent of any resources identified, the archaeologist shall prepare a final report about the monitoring and submit that report to the City’s Community Development Director, and the California Historical Resources Information System South Central Coastal Information Center at the California State University, Fullerton (CHRIS-SCCIC), as required by the California Office of Historic Preservation. The report shall include documentation and interpretation of any resources so recovered, if any. The Community Development Director shall designate repositories in the event that significant resources are recovered.
MM-10 Cultural Resources. The Applicant shall retain a Native American observer to monitor earthwork activities. The Native American observer shall represent a tribe that has ancestral ties and cultural affiliations to the project site.
MM-11
Discovery of Human Remains. If human remains are encountered during construction excavation and grading activities, Section 7050.5 of the Health and Safety Code requires that no further disturbance shall occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to Section 5097.98 of the Public Resources Code. If the remains are determined to be of Native American descent, the County Coroner has 24 hours to notify the California Native American Heritage Commission (NAHC). The NAHC will then identify the person(s) thought to be the Most Likely Descendent (MLD) of the deceased Native American, who will then help determine what course of action should be taken in dealing with the remains.

Future development. Under the [2040 General Plan/CAP] Proposed Project, future development would be required to demonstrate consistency with SCAQMD’s operational thresholds. For projects where operational emissions exceed regulatory thresholds the following measures may be used to reduce impacts. Note the following measures are not all inclusive and developers have the option to
add or substitute measures that are equally or more appropriate for the scope of their project.
Develop a project specific TDM program for residents and/or employees that provides opportunities for carpool/vanpools.
Provide onsite solar/renewable energy in excess of regulatory requirements.
Require that owners/tenants of nonresidential or multi-family residential developments use architectural coatings that are 10 grams per liter or less when repainting/repairing properties.

Preconstruction Surveys for Special-Status Plants: To mitigate impacts on special status plant species, the applicant shall implement the following measures:
Prior to initiating disturbance activities, clearance surveys for special-status plant species shall be performed by a qualified biologist(s) within the boundaries of the future project disturbances. If any special-status plants are found on the Planning Area, a qualified biologist(s) with a CDFG Scientific Collection Permit shall prepare a plan to relocate these species to suitable habitats within surrounding public open space areas that would remain undisturbed. For those species that cannot be physically transplanted, the biologist(s) shall collect seeds from the plants. (Note: Lilies generally can be transplanted in bulb-form.)
To the extent feasible the preconstruction surveys shall be completed when species are in bloom, typically between May and June and reference populations checked. Two species, the white rabbit-tobacco and San Bernardino aster, are perennial herbs that grow up to three feet in height and can be identified by their dried stalks and leaves following their blooming period.
Method of Verification: Submittal of preconstruction surveys.
Delete /Not Applicable. Notwithstanding its adopted by the Council (Resolution No. 2019-43, December 17, 2019) as part of its CEQA obligations for the 2040 General Plan/ CAP, because the project site has been previously cleared, there appears no
likelihood that any “special-status plant species” would exist thereupon.

This document analyzes whether any subsequent environmental review is required. Specifically,
this document evaluates whether the 2021 Proposed Revised BCBP would result in any new
significant impacts or a substantial increase in the severity of previously identified significant
impacts (Section 21166, PRC; Section 15162, State CEQA Guidelines). If subsequent
environmental review is not required (meaning a subsequent EIR, supplemental EIR or
subsequent mitigated negative declaration are not required), that conclusion may be documented
in an addendum (Section 15164, State CEQA Guidelines).

(c) In non-urban areas, substantially degrade the

urbanized area, would the project conflict with
applicable zoning and other regulations
governing scenic quality?
(d) Create a new source of substantial light or glare
that would adversely affect daytime or nighttime
views in the area?
Preliminary Determination: Less-than-Significant Impact
Findings of Fact: As indicated in the 2019 Approved BCBP/MND there are no scenic vistas,
scenic highways, and/or scenic resources in the general project area that would be impacted
by the site’s development. Relative to aesthetics, no project-level mitigation measures were
identified in the 2019 Approved BCBP/MND and no conditions of approval were adopted by
the Council in Resolution No. 2019-40 (November 19, 2019). Additionally, none of the
program-level mitigation measures included in the 2040 General Plan/CAP/FPEIR/MND and
adopted by the Council (Resolution No. 2019-43, December 17, 2019), appear directly
relevant to the 2021 Proposed Revised BCBP.
As compared to the 2019 Approved BCBP, the implementation of the 2021 Proposed
Revised BCBP will slightly alter the existing visual character along S. Brea Canyon Road.
The 2021 Proposed Revised BCBP replaces the 1-story multitenant building associated with
the 2019 Approved BCBP with a 1-story, 6,500 GSF single or multitenant “retail/restaurant”
(“QSR-1”) building, including the introduction of: a “fast-food restaurant” (with “drive thru”);
one or more additional unspecified “restaurants” and/or other “retail” uses therein; and the
exterior signage associated therewith.
Additionally, the 2021 Proposed Revised BCBP calls for the refurbishment of an existing,
elevated sign to include a double-faced “quick service restaurant identification pylon sign”
adjacent to the SR-60 (Pomona) Freeway. Because it is located on private property, no
permit relating thereto is required from the California Department of Transportation
(Caltrans). That freeway-adjacent signage is located in close proximity to the elevated
freeway overcrossing of Brea Canyon Road and would, therefore, not impede any existing
viewsheds. Numerous other existing elevated signs (e.g., McDonalds [21095 Golden
Springs Drive, Diamond Bar] and In-n-Out Burger [21133 Golden Springs Drive, Diamond
Bar]) are visible from the SR-60 (Pomona) Freeway in the general project area.
Excluding passing vehicles traveling along the freeway, no sight-lines originating from either
an on-site or off-site vantage point would be directly impacted. Typical freeway views in the
general project area are those of an urban setting.

Addendum Page 19
Based on the presence of numerous low-rise buildings in the general project area, the
presence of a single-story building, such as the proposed “retail/restaurant” (“QSR-1”)
building (“Parcel 2”), would be visually less dominant that either the 3-story “medical office”
(“O-1”) building (“Parcel 1”) or the 4-story “hotel” (“H-1”) (“Parcel 3”). Based on reduced bulk,
the proposed reduction in square footage (from 8,900 to 6,500 GSF) would enhance that
structure’s compatibility with the existing Brea Canyon Road streetscape.
With regards to the 2021 Proposed Revised BCBP, absent the presence of any scenic vistas
and/or scenic resources, aesthetic-related issues are primarily associated with the
introduction of outdoor lighting.
♦ Outdoor Lighting. Pole-mounted exterior lighting plans, which generally serve to
illuminate “hardscape” areas (e.g., parking lot, driveway, and walkways), and low-level
security, building, and landscape illumination remain generally as depicted in the 2019
Approved BCBP/MND. The project site is located in an urban setting and pole-mounted
street lighting and a relatively large volume of traffic is currently present along Brea
Canyon Road. The implementation of the 2021 Proposed Revised BCBP would not
materially change on-site lighting levels or adversely impact off-site areas.
Residential uses located to the north of the project site experience lower light levels.
Because those uses are separated from the project site by an existing 50-foot-wide
flood control channel, no direct light intrusion from the proposed development is
anticipated thereupon.
Focusing on outdoor lighting, the 2019 Approved BCBP/MND described the
implications of Section 130.0 (Lighting Systems and Equipment, and Electrical Power
Distribution Systems – General) in Subchapter 4 (Nonresidential, High-Rise
Residential; and Hotel/Motel Occupancies – Mandatory Requirements for Lighting
Systems and Equipment, and Electrical Power Distribution Systems) of the 2016
“Building Energy Efficiency Standards for Residential and Nonresidential Buildings,
2016 Edition” (Title 24, Part 6, CCR) (June 2015) (2016 BEES). In accordance
therewith, newly constructed nonresidential, high-rise residential, hotel/motel buildings,
outdoor lighting, and electrical power distribution systems shall comply with the
applicable provisions of Sections 130.0 through 130.5.
The California Energy Commission (CEC) updates the “California Building Energy
Efficiency Standards” on a three-year cycle. The 2019 “Building Energy Efficiency
Standards for Residential and Nonresidential Buildings” (CEC-400-2018-020-CMF)
(December 2018) (2019 BEES) went into effect on January 1, 2020 for building permit
applications submitted on or after that date. Chapter 6 (Outdoor Lighting) of the CEC’s
“2019 Nonresidential Compliance Manual” (January 2019) covers the requirements for
nonresidential outdoor lighting systems for compliance with Title 24, Part 6 (California
Energy Code) and relates to design, installation, luminaires, and lighting controls.
Compliance therewith will reduce off-site light intrusion (light trespass) and glare.
As indicated in Section 140.7 (Prescriptive Requirements for Outdoor Lighting) of the
2019 BEES, the allowed outdoor lighting shall be calculated according to “outdoor
lighting zone” in Title 24, Part 1, Section 10-114. Table 10-114-A (Lighting Zone
Characteristics and Rules for Amendments by Local Jurisdictions) therein specifies the
7.1.d

relative ambient illumination level and the Statewide default location for each lighting
zone (LZ).17 The project area is located in “Light Zone 3.”
Excessive and misdirected outdoor lighting has the potential to produce the greatest
aesthetic impacts. Similar to the 2016 BEES, Subchapter 4 (Nonresidential, High-Rise
Residential, and Hotel/Motel Occupancies – Mandatory Requirements for Lighting
Systems and Equipment, and Electrical Power Distribution Systems) of the 2019 BEES
established standards for outdoor lighting systems and equipment in nonresidential,
high-rise residential, and hotel/motel buildings.
Section 130.2 (Outdoor Lighting Controls and Equipment) of 2019 BEES outlines
specific requirements relating thereto. Under Section 130.2(c) (Controls for Outdoor
Lighting), outdoor lighting for parking and other common outdoor hardscape areas shall
be independently controlled from other electrical loads and controlled in a manner
designed to accomplish different types of energy savings, including:
◊ Daylight controls to ensure that lights are turned off during day light hours
using photocontrol astronomical time-switch or other controls (Section
130.2[c][1]);
◊ Automatic scheduling controls capable of reducing the outdoor lighting power
by at least 50 percent and separately capable of turning the lighting off during
scheduled unoccupied periods (Section 130.2[c][2][A]); and
◊ Scheduling of a minimum of two nighttime periods with independent lighting
levels.
Outdoor lighting of signage is regulated under Section 130.3 (Sign Lighting Controls)
of the 2019 BEES. All outdoor sign lighting that is on both day and night shall be
controlled with a dimmer that provides the ability to automatically reduce sign lighting
power by a minimum of 65 percent during nighttime hours.
As indicated in the “City of Diamond Bar Citywide Design Guidelines” (1998):
These guidelines are to be applied in conjunction with development standards
in implementing the City’s development review process. Although these
guidelines are expected to be followed, they are general and may be
interpreted with some flexibility in order to encourage creativity on the part of
the project designer. . .Because Diamond Bar is predominantly built-out, new
commercial development will consist primarily of infill projects and the
expansion or remodeling of existing commercial centers. There will be few
opportunities to “start from scratch.” However, elements of good design should
be utilized in projects of any scale and are just as applicable to the remodeling
or expansion of existing development as they are to large scale commercial
projects.18
17/ The following summarizes the default locations for outdoor lighting zones as specified in Section 10-114
therein: Lighting Zone 0 (Undeveloped areas of government designated parks, recreation areas, and wildlife preserves);
Lighting Zone 1 (Developed portions of government designated parks, recreation areas and wildlife preserves); Lighting
Zone 2 (Rural areas); Lighting Zone 3 (Urban areas); Lighting Zone 4 (Special use districts created by a local
government through application to the CEC.

Relative to “site planning,” the Citywide Design Guidelines specifies, in pertinent part:
◊ Buildings should be sited to be compatible with surrounding development and
reflect community character while suggesting uniqueness and quality.
◊ Adjacent residential and nonresidential uses should be segregated as is
necessary to maintain a livable residential environment, by employment of
masonry walls, landscaped berms, building orientation and activity limitations.
◊ Loading areas, access and circulation driveways, trash and storage areas,
and rooftop equipment should be located as far as possible from adjacent
residences and camouflaged where possible.
The Citywide Design Guidelines are advisory and shall “be interpreted with some
flexibility.” The 2021 Proposed Revised BCBP’s consistency with the Citywide Design
Guidelines” will be addressed through the development review process.
With regards to night-time illumination associated with the 2021 Proposed Revised
BCBP, compliance with 2019 BEES and City standards will ensure that potential sky
glow, light trespass, and glare-related impacts will remain at a less-than-significant
level under CEQA. Because they represent mandatory measures, compliance with
existing laws and regulations neither constitutes mitigation under CEQA nor are subject
to CEQA’s mitigation monitoring or reporting requirements (Section 21081.6, CEQA;
Section 15097, State CEQA Guidelines).

Findings of Fact: Relative to agricultural and forestry resources, no project-level mitigation
measures were identified in the 2019 Approved BCBP/MND or adopted by the Council in
Resolution No. 2019-40 (November 19, 2019). Additionally, none of the program-level
mitigation measures included in the 2040 General Plan/CAP/FPEIR/MND and adopted by

Preliminary Determination: Less-than-Significant with Mitigation Incorporated 20
Findings of Fact: As indicated in the 2019 Approved BCBP/MND, the approval,
construction, operation, and use of the 2019 Approved BCBP would potentially expose
sensitive receptors to significant concentrations of pollutants and odors. In response, the
City previously adopted the following mitigation measures (Resolution No. 2019-40,
November 19, 2019). Although the 2021 Proposed Revised BCBP is not anticipated to
produce significant project-specific air quality impacts, relative to the overall development of
the project site, each of the following adopted project-level mitigation measures remain
relevant to and would be imposed on the 2021 Proposed Revised BCBP:
♦ MM-4. Construction Air Quality. Relative to construction-term air quality impacts,
all site preparation and earthmoving activities shall be subject to three times, rather
than twice, daily watering.
♦ MM-5. Construction Air Quality. Relative to construction-term air quality impacts,
all heavy earthmoving equipment (e.g., graders, scrapers, heavy dozers) in excess
of 240 horsepower shall be equipped with a Level 1 diesel particulate filter.
♦ MM-6. Operational Air Quality. The Applicant shall equip all structures with
ventilation units with particulate filters with a rating of not less than Minimum
Efficiency Reporting Value (MERV) 8 as recommended by the United States
Environmental Protection Agency for automobile emission particles used in the
19/ Greenhouse gas (GHG) emissions are separately addressed in Section 3.8 (Greenhouse Gas Emissions).
20/ Prior to mitigation, the 2019 Approved BCBP/MND concluded that the 2019 Approved BCBP would potentially
produce the following significant air quality impacts: (1) expose sensitive receptors to substantial pollutant
concentrations; and (2) result in other emissions adversely affecting a substantial number of people. Although the 2021
Proposed Revised BCBP will not, in and of itself, produce additional or exacerbate any identified significant air quality
impacts, it will incrementally contribute to those identified environmental effects.

protection of superior residential and better commercial structures, including

♦ MM-7. Operational Air Quality. The hotel (Lot 3, Tentative Parcel Map No. 82066)
and the general and medical office building (Lot 1, Tentative Parcel Map No. 82066)
shall have their ventilation intakes located along their north sides of those buildings.
In addition, relating to air quality, a number of potentially relevant PMMs were included in
2040 General Plan/CAP/FPEIR and adopted by the Council (Resolution No. 2019-43,
December 17, 2019). The following adopted program-level mitigation measures initially
appear directly relevant to the 2021 Proposed Revised BCBP:
♦ PMM-AQ-1. Construction Features. Future development projects implemented
under the [2040] General Plan will be required to demonstrate consistency with
SCAQMD construction emission thresholds. Where emissions from individual
projects exceed SCAQMD thresholds, the following measures shall be incorporated
as necessary to minimize impacts. These measures do not exclude the use of
other, equally effective mitigation measures.
◊ Require all off-road diesel equipment greater than 50 horsepower (hp) used
for this project to meet current USEPA standards, which are currently Tier 4
final off-road emission standards or equivalent. Such equipment shall be
outfitted with Best Available Control Technology (BACT) devices including a
California Air Resources Board certified Level 3 Diesel Particulate Filter (DPF)
or equivalent. This DPF will reduce diesel particulate matter and NOX
emissions during construction activities.
◊ Require a minimum of 50 percent of construction debris be diverted for
recycling.
◊ Require building materials to contain a minimum 10 percent recycled content.
◊ Require materials such as paints, primers, sealants, coatings, and glues to
have a low volatile organic compound concentration compared to
conventional products. If low VOC materials are not available, architectural
coating phasing should be extended sufficiently to reduce the daily emissions
of VOCs.
♦ PMM-AQ-2. Future development. Under the [2040 General Plan/CAP] Proposed
Project, future development would be required to demonstrate consistency with
SCAQMD’s operational thresholds. For projects where operational emissions
exceed regulatory thresholds the following measures may be used to reduce
impacts. Note the following measures are not all inclusive and developers have the
option to add or substitute measures that are equally or more appropriate for the
scope of their project.
◊ Develop a project specific TDM program for residents and/or employees that
provides opportunities for carpool/vanpools.
◊ Provide onsite solar/renewable energy in excess of regulatory requirements.
◊ Require that owners/tenants of nonresidential or multi-family residential
developments use architectural coatings that are 10 grams per liter or less
when repainting/repairing properties.
◊ Require dripless irrigation and irrigation sensor units that prevent watering
during rain storms.

◊ Ensure all parking areas are wired capability of future EV charging and include
EV charging stations that exceed regulatory requirements.
Based on the Department’s further review, none of the program-level mitigation measures
included in the 2040 General Plan/CAP/FPEIR/MND and adopted by the Council (Resolution
No. 2019-43, December 17, 2019), appear directly relevant to the 2021 Proposed Revised
BCBP and have not been incorporated herein.
Although the 2021 Proposed Revised BCBP is not anticipated to produce significant air
quality impacts, relative to the overall development of the project site, each of the above
referenced project-level mitigation measures remain applicable to the 2021 Proposed
Revised BCBP. Absent significant air quality impacts, the program-level mitigation measures
are not, therefore, applicable to the 2021 Proposed Revised BCBP.
Rough grading activities associated with the implementation of the 2019 Approved BCBP
have already commenced under the authority of City-issued permits and pursuant to those
conditions of approval associated therewith. Although a revised grading plan has not been
presented for the Department’s review, only relatively minor changes thereto would be
required to accommodate the 2021 Proposed Revised BCBP. As described below,
construction-term air quality impacts attributable to those operations would be less than
those associated with the 2019 Approved BCBP.
As indicated in Table A-1 (Comparative Limited Development Analysis – 2019 Approved
BCBP and 2021 Proposed Revised BCBP [September 8, 2021]), although a change in
authorized land uses is proposed, the total square footage of all on-site development would
increase by only 385 square feet (from 118,471 to 118,856 GSF), representing an increase
of only about 0.32 percent (385/118,471 = 0.32). From an air quality perspective, that
minimal increase is deemed by the Department to be de minimis for both construction and
operational air quality impacts.
Because the construction-term air quality analysis presented in the 2019 Approved
BCBP/MND remains generally relevant hereto, no further construction-related emissions
modeling has been included herein. With mitigation, construction air quality impacts would,
therefore, be less than significant.
Operationally, the “Revised Traffic Impact Analysis Report Addendum – Brea Canyon
Business Center, Diamond Bar, California” (Linscott Law & Greenspan, August 6, 2021,
November 4, 2021, January 13, 2022) (2021 Proposed Revised BCBP/TIA) addressed the
traffic-related impacts associated with the 2021 Proposed Revised BCBP. With potential
relevancy to air quality, information from that study, including the implications thereof, include:
♦ After calculating for internal capture and pass-by trip reductions, on a “typical
weekday,” the 2021 Proposed Revised BCBP has a total trip forecast of 3,735 ADT,
with 216 trips produced in the AM peak hour and 287 trips produced in the PM peak
hour on a typical weekday.
♦ When compared to the 2019 Approved BCBP, the 2021 Proposed Revised BCBP
would produce an estimated 1,658 more daily vehicle trips, including 60 additional AM
and 100 additional PM peak hour trips, respectively. Mobile source operational
emissions would, therefore, increase by an estimated 44.4 percent (1,658/3,735 =
44.39) over those associated with the 2019 Approved BCBP.

As extracted from the 2019 Approved BCBP/MND (Table AQ-6 [Comparison of Projected
Daily Operational Emissions and Daily Criteria Values]), Table A-3 (2021 Proposed Revised
BCBP - Projected Daily Operational Criteria Emissions) presents a projection of the
estimated operational emissions attributable to the 2021 Proposed Revised BCBP. Since
mobile-source emissions constitute the greatest contributor to operational air quality
impacts, retaining all other emission sources as a constant, based on the projected increase
in ADT, mobile source emissions have been increased by 44.4 percent over those
associated with the 2019 Approved BCBP. As noted therein, projected operational
emissions attributable to the 2021 Proposed Revised BCBP remain substantially below
threshold of significance standards.

Neither the construction nor the operation of the 2021 Proposed Revised BCBP is projected
to exceed the daily threshold values formulated by the South Coast Air Quality Management
District (SCAQMD). Additionally, as indicated in the analysis presented in the 2019 Approved
BCBP/MND, with mitigation, the 2021 Proposed Revised BCBP would not result in
significant localized air quality impacts. As such, the proposed project is consistent with the
goals of the most recent “Air Quality Management Plan” (March 3, 2017) and, in that respect,
does not present a significant air quality impact.
Unlike the 2019 Approved BCBP, the 2021 Proposed Revised BCBP introduces both single
or multitenant “restaurants,” including the operation of a “drive-thru” lane where customers
can order and pick-up food orders. Two new air quality issues are introduced as a result of
those uses and those operations, namely vehicle idling within the “drive-thru” aisle and odors
attributable to the cooking of food. Both issues are separately addressed below.

♦ Vehicle Idling. Queuing vehicles, stacked in the “drive-thru” aisle, release mobile
source emissions. As reported in the “Journal of Civil and Environmental Engineering”
(January 2016):
Drive-thru users at fast food restaurants stay in their vehicle and have the
engine running instead of walking into the restaurant to place an order for food
or beverage. Although the drive-thrus are convenient, and they save time for
customers, they may have negative impacts on the air quality. Idling vehicles
waiting in lines at drive-thru facilities waste gas, harm air quality, and increase
greenhouse gas emissions.
A significant number of byproducts of burning fossil fuel may be produced
during idling, which include carbon dioxide (CO2), carbon monoxide (CO),
oxides of nitrogen (NOX) and volatile organic compounds. . .Most people do
not know that a vehicle that is idle at a drive-through facility and wait for a long
period of time produces a considerable amount of emission.21
Serving one or more restaurants, proposed is a single “drive-thru” aisle. Although the
length of the “drive-thru” aisle is not identified, the Applicant depicts a queuing capacity
of about 13 vehicles prior to potential interference attributable to additional vehicles
with other on-site parking and circulation patterns.
California’s anti-idling restrictions (Section 2485, CCR) do not currently apply to
passenger vehicles; however, as a larger portion of the future vehicles operating on
southern California’s roadways become electrical-powered, vehicle exhaust emissions
should decrease over time. In order to reduce mobile-source exhaust emissions, the
Federal Highway Administration (FHWA) recommends turning off vehicle engines
when operating within “drive-thru” aisles.22 The City does not, however, have the
statutory authority to either mandate or enforce that recommendation.
Any localized increase in mobile-source emission attributable to queuing vehicles
would be minimal since vehicle exhausts are already prevalent in the general project
area due to the project site’s proximity to the Pomona (SR-60) Freeway, Brea Canyon
Road, and Lycoming Street. The 2021 Proposed Revised BCBP’s contributions thereto
would be less than significant.
♦ Odors. Vehicles utilizing the “drive-thru” would emit odors in the form of exhaust
emissions (e.g., sulfur dioxide). Any localized increase in odorous mobile-source
emission from vehicle exhaust would be minimal since vehicle exhausts are already
prevalent in the general project area. In addition to vehicles traveling along the freeway
and proximal streets, an existing “ARCO/AM/PM” (790 S. Brea Canyon Road) gasoline
station is located at the northeastern corner of Brea Canyon Road and Lycoming Street.
Many existing sensitive receptors located within the general project area are located
within 200 feet of those sources. As a result, any incremental increase is deemed by
the Department to be de minimis.

Odors, by their very existence” are neither “good” or “bad” nor are personal perceptions
relating thereto universally held. Relative to food-related odors, certain smells (e.g.,
bread and coffee) may be viewed by many as more favorably than odors associated
with other food (e.g., fast-food grease).
Although no numeric odor concentration thresholds are presented therein, odors are
regulated, in part, by the SCAQMD through Rule 402 (Nuisance). As specified:
A person shall not discharge from any source whatsoever such quantities of
air contaminants or other material which cause injury, detriment, nuisance or
annoyance to any considerable number of persons or to the public, or which
endanger the comfort, repose, health or safety of any such persons or the
public, or which cause, or have a natural tendency to cause, injury or damage
to business or property
Cooking is recognized as an important source of particulate pollution in indoor and
outdoor environments. The processes used in cooking, such as frying, roasting, grilling,
boiling, and broiling, contribute to particle emissions.
With regards to the 2021 Proposed Revised BCBP, only limited information is presently
available concerning the use of the proposed “retail/restaurant” (“QSR-1”) building
(“Parcel 2”). For example, neither the number nor type of “restaurants” operating therein
are known. Similarly, no information has been provided concerning the type or nature
of mechanical equipment, including cooking equipment and exhaust systems,
associated therewith.
It can be reasonably assumed that the proposed “fast-food restaurant” will utilize either
a charbroiler or flat griddle to cook meat. The SCAQMD’s “Rule 1138: Control of
Emissions from Restaurant Operations” (November 14, 1997) applies to owners and
operators of commercial cooking operations, preparing food for human consumption.
The rule currently applies to chain-driven commercial charbroilers23 used to cook meat.
Under the rule, chain-driven charbroilers that cook 875 pounds of meat or more per
week must be equipped and operated with a catalytic oxidizer control device. The
combination charbroiler/catalyst must be tested and certified by SCAQMD to reduce
particulate matter (PM) and volatile organic compound (VOC) emissions.24
PMs regulated under Rule 1138 are made up of oil aerosol particles approximately 100
to 200 nanometers (nm) in size, produced from fat-containing meat during the cooking
process. In response to this rule, regulated chain-driven charbroilers are now outfitted
with high temperature oxidation catalysts located just above the hot cooking surface,
mitigating these nanometer-scale oil aerosol particles. While chain-driven charbroilers
23/ “Charbroilers” are defined therein to mean “a cooking device composed of the following three major
components: a grated grill, a high-temperature radiant surface and a heat source” (SCAQMD, Rule 1138).
24/ Commercial under-fired charbroilers (UFCs), which are similar to a home BBQ, employing a metal grill with a
heat source below and venting exhausts through a restaurant’s hood system, are not regulated under SCAQMD Rule
1138. As reported in the Federal Register: “Several times over the past 20 years and most recently in 2009, the [South
Coast Air Quality Management] District considered amending Rule 1138 to regulate PM emissions from UFCs, but to
date the District has not identified control measures for UFCs that are both technologically and economically feasible
for implementation in the South Coast. Although the Bay Area Air Quality Management District (BAAQMD) and New
York City Department of Environmental Protection (NYDEP) have adopted rules that require controls for UFCs, neither
agency has yet confirmed that any regulated sources that are subject to its rules have successfully installed and
operated certified UFC control technologies” (85 FR 40026-40057, July 2, 2020).

are primarily used in large fast-food restaurants, an estimated 85 percent of total
restaurant smoke emissions are produced by open underfire charbroilers.25
Studies conducted by the University of California, Pomona prior to the rule’s adoption
found that underfired charbroiling is the cooking method producing the largest amount
of emissions (both PM and VOC) from all appliances tested.
The wide range of emissions from underfired charbroiling depends on the type of food
cooked. Hamburger meat (25 percent fat content) produced the most PM emissions
(average 32.65 pounds PM/1,000 pounds cooked). Fish gave the least amount of
emissions (averaging 3.3 pounds PM/1,000 pounds cooked), with chicken in the
midrange (averaging 10.48 pounds PM/1,000 pounds cooked). Similarly, VOC
emissions ranked the same, with hamburger producing the most, fish the least, and
chicken in between. The physical and chemical composition of the PM was not
analyzed but other researchers have shown that the decomposition of fat, meat
tenderizers, and other meat additives causes the release of gaseous organics
(aldehydes, alcohols, organic acids, and nitrogen and sulfur compounds).
As reported in the “Journal of Atmospheric Chemistry and Physics” (2021):
Organic aerosol (OA) has important impacts on air quality, climate, and human
health. OA is often composed of thousands of organic compounds formed
from a variety of sources. In urban areas, particulate emissions from food
cooking account for a significant fraction of OA. Furthermore, volatile organic
compounds (VOCs) are also emitted, and they can undergo oxidation and
form secondary organic aerosol (SOA). Recent studies have reported the
formation of SOA from meat charbroiling and heated cooking oils. Therefore,
food cooking activities have substantial impacts on air quality in and downwind
of urban areas.
The emission of VOCs from cooking is highly variable and depends on a
number of factors such as cooking style, food, ingredients, and temperature.
Of the different classes of VOCs characterized in these studies, aldehydes
have been shown to be the major group of VOCs emitted from cooking oils.
These VOCs are chemically produced upon heating via peroxyl radical
reactions of the fatty acids.26
Relative to pre-rule emissions, implementation of Rule 1136 has resulted in emission
reductions, a decrease in visible emissions violations for this industry, and has
alleviated odor and smoke complaints against restaurants operating in residential
neighborhoods.27

As specified in Section 22.16.030 (Air Emissions), Title 22 (Development Code) of the
DMBC: “Odor emissions. Land use activities that may produce odors or noxious
matter (e.g., fumes, gases, vapors, etc.) shall comply with SCAQMD’s and
regulations, including Rule 402 which prohibits the formation of an odor nuisance.”
As further required, in part, in Section 8.16.550 (Placement of Containers for

In lieu of the approved “medical office” use on “Parcel 2,” the introduction of both a
“fast-food restaurant” (with “drive-thru”) and one or more unspecified “restaurants”
(collectively totaling 6,500 GSF) will introduce new potentially odor-generating uses on
the northwestern portion of the project site, adjacent to the existing “Farmer Boys
Restaurant” (810 Brea Canyon Road, Diamond Bar). It is noted that “Farmer Boys
Restaurant” closely abuts existing residential units to the east, separated only by the
restaurant’s parking lot and an existing County flood control channel. Unlike the 2021
Proposed Revised BCBP, “Farmer Boys Restaurant” is an existing use and not subject
to the same siting considerations as may be applied to newly permitted uses.
Odors are generally considered to be an annoyance rather than a health hazard. An
individual’s reaction to a perceivable odor can range from psychological (e.g., irritation)
to physiological (e.g., circulation and respiratory effects). The ability to detect odors
varies considerable among the general population and can be quite subjective. Odors
(odours) have been defined as:
Odour is perceived by our brains in response to chemicals present in the air
we breathe. Odour is the effect that those chemicals have upon us. Humans
have sensitive senses of smell and they can detect odour even when
chemicals are present in very low concentrations. Most odours are a mixture
of many chemicals that interact to produce what we detect as an odour.
Odour-free air contains no odorous chemicals whilst fresh air is usually
perceived as being air that contains no chemicals or contaminants that could
cause harm, or air that smells “clean.” Fresh air may contain some odour, but
these odours will usually be pleasant in character such as the smell of freshly
mown grass or sea spray. Different life experiences and natural variation in
the population can result in different sensations and emotional responses by
individuals to the same odorous compounds. Because the response to odour
is synthesised in our brains, other senses such as sight and taste, and even
our upbringing, can influence our perception of odour and whether we find it
acceptable, objectionable or offensive.28
Unlike some uses where operational odors may be only occasionally noticeable beyond
the property’s boundaries, subject to the application and efficacy of odor control and

ventilation systems associated therewith, based on exhausts attributable to cooking
operations, odors emanating from the “fast-food restaurant” and from other unspecified
“restaurants” may be evident during all hours of operation.
Certain distinctive smells are inherently a part of the urban and rural environments.
With regards thereto, the term “smellscape” has been used to refer “to the overall smell
environment, but with the acknowledgment that as human beings, we are only capable
of detecting this partially at any one point of time, although we may carry a mental
image or memory of the smellscape in its totality.” 29 It has been noted that:
Fast food restaurants, specifically those production a high turnover of fried
foods, release the most concentrated odour and grease emissions and require
more sophisticated and complicated ventilation systems than other restaurant
types. The large chain restaurants are well versed in dealing with legal
requirements for ventilation, with their formulaic kitchen and restaurant layouts
incorporating standard systems. However, many smaller independent
businesses need detailed guidance from local officials to ensure compliance
with equipment and maintenance requirements. Odours from fast food
premises are commonly detected in urban environments, perceived in mixed
terms and influenced by associations with brand identity and food types.30
Cooking odors are already present in the general project area. “Farmer Boys
Restaurant” (810 Brea Canyon Road, Diamond Bar) is generally located at a
comparable distance from proximal sensitive receptors located along Lycoming Street
as associated with the proposed “retail/restaurant” (“QSR-1”) building (“Parcel 2”).
Although the proposed “hotel” also includes food-service operations, absent an on-site
restaurant readily available to non-hotel guests, it is anticipated that food preparation
activities would be confined to limited hours and involve a limited menu. In addition,
because the “hotel” is separated from the nearest residential receptor by a distance of
approximately 246 feet and because kitchen exhausts would discharge above the
roofline, cooking odors would be expected to be diluted to a non-perceptible level.
Statewide regulatory provisions included in the California Retail Food Code (CRFC)
relating to the control and abatement of odors include, but may not be limited to:
◊ Section 114149.1(a), CRFC. Mechanical exhaust ventilation equipment shall
be provided over all cooking equipment as required to effectively remove
cooking odors, smoke, steam, grease, heat, and vapors. All mechanical
exhaust ventilation equipment shall be installed and maintained in accordance
with the California Mechanical Code.
◊ Section 11425.1(a), CRFC. All refuse, recyclables, and returnables shall be
kept in nonabsorbent, durable, cleanable, leakproof, and rodentproof
containers and shall be contained so as to minimize odor and insect
development by covering with close-fitting lids or placement in a disposable
bag that is impervious to moisture and then sealed.

◊ Section 11425.1(e), CRFC. Refuse, recyclables, and returnables shall be
removed from the premises at a frequency that will minimize the development
of objectionable odors and other conditions that attract or harbor insects and
rodents.
◊ Section 114276(c), CRFC. (1) Toilet rooms shall be separated by well-fitted,
self-closing doors that prevent the passage of flies, dust, or odors. (2) Toilet
room doors shall be kept closed except during cleaning and maintenance
operations.
Cooking odors (molecules) generated by the cooking of animal and vegetable matter
results in an extremely complex mixture of PMs and VOCs. Although a small
percentage of these odors may be found in grease particles, the vast majority of those
odors exist separately in the air stream as vapor.
Based on proximity to the Pomona (SR-60) Freeway and Brea Canyon Road and the
presence of any existing “Farmer Boys Restaurant” (810 Brea Canyon Road, Diamond
Bar) and “ARCO/AM/PM” (790 S. Brea Canyon Road) gasoline station, both
automobile and cooking-related emissions are already present on and near the project
site. Additionally, perceptible odors dissipate as the distance between the source and
receptor increases or when intervening obstructions (e.g., building placement and
landscaping) redirect air-borne particulates upward and/or away from receptor
locations. The implementation of the 2021 Proposed Revised BCBP might
incrementally contribute any associated odors but would not result in the introduction
of new odors that are not presently present in the general project area.
The minimum distance between the proposed “retail/restaurant” (“QSR-1”) building
(“Parcel 2”) and the rear yard of the nearest residential receptor located along Lycoming
Street (21048 Lycoming Street) is approximately 116 feet. The minimum distance
between the proposed “outdoor dining area” associated therewith and the rear yard of
the nearest residential receptor is about 104 feet. As proposed, a minimum 6-foot-tall
solid, continuous, perimeter concrete masonry block (CMB) wall, or equivalent, shall
be constructed along the property’s northern property line. In addition, extensive
landscaping is proposed along the project site’s northern boundary. That wall and that
landscape would help to dissipate and redirect cooking odors.
With the incorporation of those mitigation measures identified in the 2019 Approved
BCBP/MND, the construction and operation of the 2021 Proposed Revised BCBP will have
less-than-significant air quality impacts under CEQA.

Preliminary Determination: No Impact
Findings of Fact: No biological resource-related project-level mitigation measures were
identified in the 2019 Approved BCBP/MND or adopted by the Council (Resolution No. 2019-
40, November 19, 2019). None of the program-level mitigation measures included in the
2040 General Plan/CAP/FPEIR/MND and adopted by the Council (Resolution No. 2019-43,
December 17, 2019) appear directly relevant to the 2021 Proposed Revised BCBP.
With the initiation of rough grading operations associated with the 2019 Approved BCBP,
grading and grubbing operations have resulted in direct disturbance to near-surface areas,
including the location of the proposed “retail/restaurant” (“QSR-1”) building (“Parcel 2”).
The general development footprint of the 2019 Approved BCBP and 2021 Proposed Revised
BCBP are similar. Both projects call for the same number of buildings, in the same general
locations, and at the same proposed heights. Potential impacts on both on-site and near-
site biological resources have already fully manifested with the initiation of those grading
activities. No additional biological resource impacts are, therefore, attributable to the 2021
Proposed Revised BCBP.
As indicated in the documents accompanying the 2040 General Plan/CAP (Volume III:
Existing Conditions Report Environmental Constraints and Opportunities; and Public
Facilities, Services, and Utilities, January 10, 2017), the project site is depicted as
“developed.” As defined therein: “Developed/urban areas have been physically altered to
the point where they can no longer support native vegetation.”31
From a biological resource perspective, the 2021 Proposed Revised BCBP neither increases
the area of physical disturbance nor results in the removal of any additional vegetation,
including “protected trees” (Section 22.38.030, DBMC), beyond that disclosed in the 2019

Approved BCBP/MND. The project site does not contain habitat (including any riparian
habitat) or any sensitive natural communities. Specifically, no “oak, walnut trees, or other
small pockets of native habitat” exist on the project site. The site is not within any Habitat
Conservation Plan, Natural Community Conservation Plan, and/or other approved local,
regional, or State habitat conservation plan. Additionally, the 2021 Proposed Revised BCBP
does not result in the disturbance of any additional “waters of the State” and/or “waters of
the United States,” including wetlands.
The construction and operation of the 2021 Proposed Revised BCBP will have no impact on
biological resources.

Preliminary Findings: Less-than-Significant Impact with Mitigation Incorporated 32
Findings of Fact: The general development footprints associated with the 2019 Approved
BCBP and 2021 BCBP Proposed Revised BCBP are similar. Both projects call for the same
number of buildings, in the same general locations, and at the same proposed heights.
Excavation activities associated with the 2021 Proposed Revised BCBP will not occur at
greater depths that associated with the 2019 Approved BCBP.
32/ Prior to mitigation, the 2019 Approved BCBP/MND concluded that the 2019 Approved BCBP would potentially
produce the following significant cultural resource impacts: (1) cause a substantial adverse change in the significance
of a historical resource as pursuant to Section 15064.5 in Title 14 of the California Code of Regulations; and (2) disturb
any human remains, including those interred outside of dedicated cemeteries. Although the 2021 Proposed Revised
BCBP will not, in and of itself, produce additional or exacerbate any identified significant cultural resource impacts,
because certain statutory and regulatory provisions apply to all construction projects, those provisions, in the form of a
mitigation measure (“MM-11”), has been retained.

As indicated in the 2019 Approved BCBP/MND: “[T]he project site is considered to be
sensitive for the presence of both prehistoric and historic resources. Monitoring of future
earth-disturbing and trenching activities, particularly those that occur below the depth of
surficial fill material, could yield information important in prehistory or history” (Section
15064.5[a][3][D], State CEQA Guidelines).
As a result, with regards to the 2019 Approved BCBP, because the needless loss of any
such “information important in prehistory or history” could be potentially significant, As
presented in the 2019 Approved BCBP/MND, in response to potential cultural resource
impacts, the City adopted the following project-level mitigation measures (Resolution No.
2019-40, November 19, 2019):
♦ MM-8. Cultural Resources. Prior to the issuance of a grading permit, a qualified
archaeologist, meeting the Secretary of the Interior’s Standards and Guidelines for
Archaeology and Historic Preservation (48 FR 44716, National Parks Service,
September 29, 1983) shall be retained by the Applicant to oversee the monitoring
of initial ground disturbing activities, including all trenching and excavation activities
occurring to a depth greater than three feet below surface grades. The archeologist
shall conduct excavation monitoring activities for the purpose of identifying the
potential presence of any significant historic or prehistoric cultural resources
located within the project boundaries.
o Delete / No Longer Applicable. A site-specific grading permit was
issued for the 2019 Approved BCBP and rough grading activities
associated therewith have previously commenced. Although additional
grading activities associated with the 2021 Proposed Revised BCBP will
occur, with the commencement of rough grading activities, including the
associated disturbance of the entire project site, this project-level
mitigation measure was effectively implemented and no longer remains
applicable to the 2021 Proposed Revised BCBP. No further compliance
therewith is, therefore, deemed by the Department to be required.
♦ MM-9. Cultural Resources. If cultural resources are identified during monitoring of
the ground disturbing activities, the supervising archaeologist shall be empowered
to temporarily halt construction in the vicinity of any such discovery while its
significance is being evaluated. All cultural resources that may be so recovered will
be documented on California Department of Parks and Recreation Site Forms and
filed with the California Historical Resources Information System South Central
Coastal Information Center at the California State University, Fullerton (CHRIS-
SCCIC). Independent of any resources identified, the archaeologist shall prepare a
final report about the monitoring and submit that report to the City’s Community
Development Director, and the California Historical Resources Information System
South Central Coastal Information Center at the California State University,
Fullerton (CHRIS-SCCIC), as required by the California Office of Historic
Preservation. The report shall include documentation and interpretation of any
resources so recovered, if any. The Community Development Director shall
designate repositories in the event that significant resources are recovered.
o Delete / No Longer Applicable. A site-specific grading permit was
issued for the 2019 Approved BCBP and rough grading activities
associated therewith have previously commenced. Although additional
grading activities associated with the 2021 Proposed Revised BCBP will

occur, with the commencement of rough grading activities, including the
associated disturbance of the entire project site, this project-level
mitigation measure was effectively implemented and no longer remains
applicable to the 2021 Proposed Revised BCBP. No further compliance
therewith is, therefore, deemed by the Department to be required.
♦ MM-10. Cultural Resources. The Applicant shall retain a Native American
observer to monitor earthwork activities. The Native American observer shall
represent a tribe that has ancestral ties and cultural affiliations to the project site.
o Delete / No Longer Applicable. A site-specific grading permit was
issued for the 2019 Approved BCBP and rough grading activities
associated therewith have previously commenced. Although additional
grading activities associated with the 2021 Proposed Revised BCBP will
occur, with the commencement of rough grading activities, including the
associated disturbance of the entire project site, this project-level
mitigation measure was effectively implemented and no longer remains
applicable to the 2021 Proposed Revised BCBP. No further compliance
therewith is, therefore, deemed by the Department to be required.
♦ MM-11. Discovery of Human Remains. If human remains are encountered during
construction excavation and grading activities, Section 7050.5 of the Health and
Safety Code requires that no further disturbance shall occur until the County
Coroner has made the necessary findings as to origin and disposition pursuant to
Section 5097.98 of the Public Resources Code. If the remains are determined to
be of Native American descent, the County Coroner has 24 hours to notify the
California Native American Heritage Commission (NAHC). The NAHC will then
identify the person(s) thought to be the Most Likely Descendent (MLD) of the
deceased Native American, who will then help determine what course of action
should be taken in dealing with the remains.
o Retain. On-site grading activities conducted to date have not revealed the
presence of any human remains and the likelihood of such discover
substantially reduced as a result thereof. Although existing regulatory
obligations associated with the discovery of human remains exists outside
the context of CEQA, relative to the overall development of the project site,
“MM-11” has nevertheless been retained herein.
Although no human remains are anticipated to be present on the project
site, pursuant to Section 7050.5 of the California Health and Safety Code
(H&SC), project-level mitigation measure “MM-11” remains potentially
applicable throughout the term of the construction process.
With the City’s issuance of a rough grading permit associated with the 2019 Approved BCBP,
project-level mitigation measure “MM-8,” “MM-9,” and “MM-10” were effectively implemented
and would no longer appear to remain applicable to the 2021 Proposed Revised BCBP. No
further compliance therewith is, therefore, deemed by the Department to be required. The
2021 Proposed Revised BCBP’s potential impacts to cultural resources would be less than
significant with the incorporation of the retained mitigation measure from the 2019 Approved
BCBP/MND.

(a) Result in potentially significant environmental
impact due to wasteful, inefficient, or

(b) Conflict with or obstruct a State or local plan for
renewable energy or energy efficiency?
Preliminary Determination: Less-than-Significant Impact
Findings of Fact: Relative to energy, no project-level mitigation measures were identified
in the 2019 Approved BCBP/MND or adopted by the Council in Resolution No. 2019-40
(November 19, 2019). None of the program-level mitigation measures included in the 2040
General Plan/CAP/FPEIR/MND and adopted by the Council (Resolution No. 2019-43,
December 17, 2019), appear directly relevant to the 2021 Proposed Revised BCBP.
With regards to energy impacts, as specified under Section 15126.2 (Consideration and
Discussion of Significant Environmental Impacts) of the State CEQA Guidelines:
If analysis of the project’s energy use reveals that the project may result in
significant environmental effects due to wasteful, inefficient, or unnecessary
consumption use of energy, or wasteful use of energy resources, the EIR shall
mitigate that energy use. This analysis should include the project’s energy use for
all project phases and components, including transportation-related energy, during
construction and operation. In addition to building code compliance, other relevant
considerations may include, among others, the project’s size, location, orientation,
equipment use and any renewable energy features that could be incorporated into
the project. (Guidance on information that may be included in such an analysis is
presented in Appendix F.) This analysis is subject to the rule of reason and shall
focus on energy use that is caused by the project. This analysis may be included in
related analyses of air quality, greenhouse gas emissions, transportation or utilities
in the discretion of the lead agency.
As extracted from the 2019 Approved BCBP/MND (Table AQ-6 [Comparison of Projected
Daily Operational Emissions and Daily Criteria Values]), Table A-3 (2021 Proposed Revised
BCBP - Projected Daily Operational Criteria Emissions) presents a projection of the
estimated operational emissions attributable to the 2021 Proposed Revised BCBP. As noted
therein, criteria emissions attributable to energy consumption constitutes only a minimal
component of projected operational emissions. From an air quality perspective, that minimal
increase in criteria emissions associated with energy consumption is deemed by the
Department to be de minimis.
As indicated in Table A-1 (Comparative Limited Development Analysis – 2019 Approved
BCBP and 2021 Proposed Revised BCBP [September 8, 2021]), although a change in
authorized land use is being proposed, the total square footage of all on-site development

would increase by only 385 GSF, representing an increase of only about 0.32 percent.
Although a different mix of land uses is proposed, when examined in total, energy
consumption during construction would, therefore, be expected to be similar. Operationally,
based on a consumption per square foot metric, energy consumption associated with the
2021 Proposed Revised BCBP would be generally similar to that associated with the 2019
Approved BCBP.
The CEC’s “Building Energy Efficiency Standards for Residential and Nonresidential
Buildings, 2019 Edition” (24 CCR Part 6) (2019 CEC) sets energy and water design
standards for residential and nonresidential buildings. The 2019 CEC includes cost-effective
energy efficiency requirements for newly constructed buildings, additions and alterations to
existing buildings. Effective on January 1, 2020, among other things, the 2019 CEC: (1)
improved envelope efficiency, which refers to improving the insulation windows, exterior
walls, floors, and roof of a building; and (2) promoted grid harmonization strategies that
maximize self-utilization of photovoltaic output and limit exports to the grid. It is projected
that compliance with those standards will result in a Statewide reduction of 700,000 tons of
CO2 emissions over three years.
On a three-year cycle, the 2019 CEC updated the 2016 “Building Energy Efficiency
Standards for Residential and Nonresidential Buildings.” The CEC is considering the scope
and analysis needed now for the 2022 CEC (effective January 1, 2023).
The BSC’s “California Green Building Standards, 2019 Edition” (24 CCR Part 11) (2019
CalGreen) contains both mandatory requirements and voluntary measures for new
residential and nonresidential buildings throughout California. The 2019 CalGreen improves
public health, safety, and general welfare by enhancing the design and construction of
buildings through the following construction practices: (1) planning and design; (2) energy
efficiency; (3) water efficiency and conservation; (4) material conservation and resource
efficiency; and (5) environmental quality. In addition, the 2019 CalGreen promotes the
reduction of construction waste, makes buildings more efficient relative to the use of
materials and energy, and reduces environmental impact during and after construction.
Compliance with the 2019 CEC and 2019 CalGreen or subsequent versions thereof will
ensure that the 2021 Proposed Revised BCBP neither results in the “wasteful, inefficient,
and unnecessary consumption of energy” nor manifests as a significant energy-related
impact under CEQA. Additionally, based on such compliance, the 2021 Proposed Revised
BCBP will neither conflict with nor obstruct a State or local plan for renewable energy or
energy efficiency.
The construction and operation of the 2021 Proposed Revised BCBP will have less-than-
significant energy impacts under CEQA.

As noted in the 2019 Approved BCBP/MND, as evidenced by the DOC’s “Earthquake Zones
of Required Investigation – San Dimas Quadrangle” (March 25, 1999), the project site is not
subject to the ground rupture attributable to a known earthquake fault, as delineated on the
most recent Alquist-Priolo Earthquake Fault Zoning Map.
Rough grading activities associated with the implementation of the 2019 Approved BCBP
have already commenced under the authority of City-issued permits and pursuant to those
conditions of approval associated therewith. Rough grading activities, conducted under the
auspices of a State-licensed geotechnical engineer, served to effectively address a number
of previously identified geologic, geotechnical, and soils-related hazards, ensuring, to the
maximum extent feasible, the elimination of those project-related hazards. Associated
grading activities did not occur at depths sufficient to directly impact groundwater resources.
The general development footprint of the 2019 Approved BCBP and 2021 Proposed Revised
BCBP projects are similar. Both projects call for the same number of buildings, in the same
general locations, and at the same proposed heights. With the exception of the City’s
adoption of the 2019 CBC and 2019 CalGreen (Ordinance No. 04[2019], December 3, 2019)
and the initiation of on-site grading activities, no changes to localized and/or regional geology
have occurred following the adoption of the 2019 Approved BCBP/MND.
As part of the 2021 Development Application, the Applicant submitted:
♦ “Update No. 3 to Geotechnical Investigation – Proposed Brea Canyon Business Park,
850 Brea Canyon Road, Diamond Bar, California” (Geotechnical Professionals, Inc.,
April 13, 2019); and
♦ “Update No. 4 to Geotechnical Investigation – Proposed Brea Canyon Business Park,
850 Brea Canyon Road, Diamond Bar, California” (Geotechnical Professions, Inc.,
September 28, 2021).
As indicated therein, the 2021 Proposed Revised BCBP remains geotechnically feasible.
Those studies recommended that the previous geotechnical investigations be amended to
reflect the requirements of the 2019 CBC. The amended recommendations include seismic
considerations such as ground motions and liquefaction analysis. Other recommendations
pertaining to foundational concrete in the 2016 CBC did not change; however, the 2019 CBC
should be the referenced building code for these recommendations.
Effective on January 1, 2019, the “California Building Standards Code, 2019 Edition” (Title
24, CCR) is the minimum standard established in law for the design and construction of
building and structures in California. State law mandates that local governments enforce
these regulations but they are also authorized (through the adoption of local ordinances) to
impose more restrictive building standards than provided therein.
Title 24 is published in its entirety every three years by order of the State Legislature, with
supplements published in intervening years. Title 24 consists of the following 13 separate
parts: (1) Part 1 (California Administrative Code); (2) Part 2 (California Building Code); (3)
Part 2.5 (California Residential Code); (4) Part 3 (California Electrical Code); (5) Part 4
(California Mechanical Code); (6) Part 5 (California Plumbing Code); (7) Part 6 (California

Code); (10) Part 10 (California Existing Building Code); (11) Part 11 (California Green
Building Standards Code); and (12) Part 12 (California Referenced Standards Code). Part 7
is reserved. Title 24 is maintained by the California Building Standards Commission
(CBSC) which is granted the authority to oversee processes related to the California building

codes by California Building Standards Law. The “California Building Code, 2019 Edition”
(Title 24, Part 2) (2019 CBC) became effective on January 1, 2020.
The “California Building Standards Code, 2016 Edition” (2016 CBC) remains in effect and is
applicable to all plans and specifications for and to construction performed where the
application for a building permit is received on or before December 31, 2019. In accordance
with Section 18938.5 of the H&SC, all applications for a building permit submitted on or after
January 1, 2020 are subject to compliance with the 2019 CBC. Building permits for the 2021
Proposed Revised BCBP have not yet been submitted to the Department.
All applications for building permits submitted on or after January 2, 2022 will be subject to
compliance with the yet to be adopted “California Building Code, 2022 Edition” (2022 CBC),
including any amendments thereto that may be subsequently adopted by the City. Based on
the date with which building permit applications are received, either the 2019 CBC or the
2022 CBC would apply thereto.
As indicated in the 2019 Approved BCBP/MND, a number of potentially significant geologic,
geotechnical, seismic, and/or soils-related impacts were identified in response to the 2019
Approved BCBP. Each of those impacts could, however, be effectively mitigated to a less-
than-significant level under CEQA through the implementation of those geologic,
geotechnical, seismic, and soils-related recommendations in the studies listed in “MM-12.”
Similarly, subsequent Applicant-submitted geotechnical investigations demonstrate that,
with the implementation of those recommendations contained therein, the 2021 Proposed
Revised BCBP remains feasible from a geologic, geotechnical, seismic, and soil-related
perspective.
Compliance with “Revised MM-12,” as amended, will continue to reduce potential geologic,
geotechnical, seismic, and soils-related impacts associated with the 2021 Proposed Revised
BCBP to a less-than-significant level under CEQA.

(b) Conflict with any applicable plan, policy, or
regulation adopted for the purpose of reducing
the emissions of greenhouse gases?
Preliminary Determination: Less-than-Significant Impact
Findings of Fact: No project-level mitigation measures addressing greenhouse gas (GHG)
emissions were presented in the 2019 Approved BCBP or adopted by the Council
(Resolution No. 2019-40, November 19, 2019). No program-level mitigation measures
explicitly addressing GHG emissions were included in the 2040 General Plan/CAP/
FPEIR/MND or adopted by the Council (Resolution No. 2019-43, December 17, 2019).
Rough grading activities associated with the implementation of the 2019 Approved BCBP
have already commenced under the authority of City-issued permits (December 7, 2020)
and pursuant to those conditions of approval associated therewith. Associated GHG
emissions attributable to those activities are, therefore, not assignable to the 2021 Proposed
Revised BCBP. Only minor additional grading activities beyond those associated with the
2019 Approved BCBP would be required for the construction of the 2021 Proposed Revised
BCBP. In addition, as indicated in Table A-1 (Comparative Limited Development Analysis –
2019 Approved BCBP and 2021 Proposed Revised BCBP [September 8, 2021]), although
a change in authorized use is proposed, the total square footage of all on-site development
would increase by only 385 GSF.
From a construction perspective, the GHG emissions analysis presented in the 2019
Approved BCBP/MND presents an overly conservative assessment of projected GHG
emissions attributable to the 2021 Proposed Revised BCBP.
With respect to operational impacts, the “City of Diamond Bar Climate Action Plan 2040”
(2040 CAP) was not adopted until after the approval of the 2019 Approved BCBP/MND
(Resolution No. 2019-45, December 17, 2019) and the approval of the 2019 Approved BCBP
by the Council (Resolution No. 2019-42, November 19, 2019). The 2040 CAP now serves
as the City’s “Qualified Greenhouse Gas Reduction Strategy” (Section 15183.5[b][1][A],
State CEQA Guidelines).
As specified, in part, in Section 15183.5 of the State CEQA Guidelines:
(a) Lead agencies may analyze and mitigate the significant effects of greenhouse
gas emissions at a programmatic level, such as in a general plan, a long range
development plan, or a separate plan to reduce greenhouse gas emissions.
Later project-specific environmental documents may tier from and/or
incorporate by reference that existing programmatic review. Project-specific
environmental documents may rely on an EIR containing a programmatic
analysis of greenhouse gas emissions as provided in Section 15152 (tiering),
15167 (staged EIRs) 15168 (program EIRs), 15175–15179.5 (Master EIRs),
15182 (EIRs Prepared for Specific Plans), and 15183 (EIRs Prepared for
General Plans, Community Plans, or Zoning).
(b) Plans for the Reduction of Greenhouse Gas Emissions. Public agencies may
choose to analyze and mitigate significant greenhouse gas emissions in a plan
for the reduction of greenhouse gas emissions or similar document. A plan to
reduce greenhouse gas emissions may be used in a cumulative impacts
analysis as set forth below. Pursuant to Sections 15064(h)(3) and 15130(d),

a lead agency may determine that a project’s incremental contribution to a
cumulative effect is not cumulatively considerable if the project complies with
the requirements in a previously adopted plan or mitigation program under
specified circumstances.
With regards to the 2021 Proposed Revised BCBP, the 2040 CAP constitutes a “long range
development plan” and a “previously adopted plan or mitigation program.” In accordance
therewith, this 2021 Proposed Revised BCBP/Addendum is “tiered” from the 2040 General
Plan/CAP/FPEIR. The 2040 General Plan/CAP/FPEIR did not identify cumulative GHG
emissions as a potentially significant impact and no specific program-level mitigation
measures associated therewith were included therein. As specified in the “Final
Environmental Impact Report, State Clearinghouse No. 2018051066 - Findings of Fact and
Statement of Overriding Considerations” (December 17, 2019) (2040 General Plan/CAP/
FPEIR/Findings):
♦ Projects that demonstrate consistency with the updated Diamond Bar [2040]
General Plan and [2040] CAP will be subject to streamlining CEQA review process
for mitigation of GHG emissions, pursuant to CEQA Guidelines §15183.5.34
♦ With the policies set forth in the [2040] General Plan Update, Diamond Bar will meet
its mandated GHG reduction targets without being subject to additional GHG
reduction measures.35
As further specified in the 2040 CAP:
Project-specific environmental documents prepared for projects consistent with
the [2040] General Plan may rely on the programmatic analysis contained in the
[2040] CAP and the [2040 General Plan/CAP] [FP]EIR certified for the Diamond
Bar [2040] General Plan.36
Although the 2040 CAP did not expressly list separate goals and policies exclusively
applicable thereto, included in Appendix C (Applicable General Plan Policies) therein was a
listing of those goals and policies contained in the 2040 General Plan/CAP deemed to be
“applicable” to the 2040 CAP. From Appendix C of the 2040 CAP, based on the
Department’s review of the most recent development plans (G/A/A, September 8, 2021),
those goals and policies deemed by the Department to be applicable to the 2021 Proposed
Revised BCBP are presented in Table A-4 (2021 Proposed Revised BCBP - Preliminary
Consistency Analysis – Applicable 2040 Climate Action Plan Goals and Policies [September
8, 2021]).3738 With regards to the proposed project, each of those goals and objective are
categorized as “consistent,” “potentially inconsistent,” or “not applicable.”
34/ City of Diamond Bar, Final Environmental Impact Report, State Clearinghouse No. 2018051066 - Findings of
Fact and Statement of Overriding Considerations, December 17, 2019 (Resolution No. 2019-43), p. 7.

36/ Op. Cit., Diamond Bar Climate Action Plan 2020, City Council Resolution No. 2019-45, adopted December 17,

37/ The goals and policies referenced therein are as listed in Appendix C (Applicable General Plan Policies) in
the 2040 CAP and are deemed by the Department to be potentially applicable hereto.
38/ Because they often deal with broad and often competing issues and interests, not all policies lend themselves
to easy categorization as to either their applicability to a proposed action or with regards to a project’s compliance or
degree of compliance therewith. Many general plan policies constitute visionary declarations and/or broad-based
platitudes, incorporating terminology which is neither defined therein nor which directly lends itself to a universal
(consistent) interpretation. In its assessment of “consistency” therewith, the Department has: (1) utilized its best efforts
to understand the intent and meaning of those policies: (2) sought to identify those policies’ potential application to the
2021 Proposed Revised BCBP; and (2) concluded that certain policies neither directly apply thereto nor reasonably
allow for a consistency assessment therewith.

Community Character and Placement (Continued)
CC-P-91
Encourage pedestrian orientation in mixed-use development using a variety of site planning and architectural strategies, such as locating and orienting buildings to street frontages, plazas, or pedestrian paseos; providing visual transparency through fenestration; entries and arcades close to the street edge and sidewalk; and/or incorporating porches, patios, or outdoor spaces that overlook or interact
with front yards or sidewalks.
Not Applicable. Unless otherwise interpreted by the City’s decision-making body, the 2021 Proposed Revised BCBP is not a “mixed-use development.”
CC-P-181
As large vacant or underutilized sites are developed or redeveloped, maximize multi-modal accessibility with fine-grained street networks and walkable block sizes. Generally limit new block sizes to a maximum of about 400 feet in length. Mid-block plazas or alleys may be considered if the intent is to ensure fine-grained patterns where pedestrian access can be accommodated in intervals no more than 400 feet apart.
Consistent. Pursuant to Section 22.40 of DBMC, all
nonresidential projects of 100,000 square feet and more shall provide transit waiting shelters (bus pullouts, bus pads and bus shelters). The 2021 Proposed Revised BCBP includes, as a component to its transportation demand management plan, the provision of a new bus shelter and new bus pad at the existing bus stop located along Brea Canyon Road to north of the project site.
CC-P-191 Through development review, ensure that new development provides an integrated pattern of streets and pedestrian paths with connections within and between neighborhoods.
Consistent. The 2021 Proposed Revised BCBP is subject to the City’s “development review” process.
CC-P-201
Create pedestrian-and bicycle-only pathways to enhance neighborhood
interconnectivity where street connections are limited due to existing cul-de-sac or dead-end conditions, grade separation, property ownership, or topographical challenges.
Not Applicable. The 2021 Proposed Revised BCBP is a commercial center and does not have the opportunity to “enhance neighborhood interconnectivity.”
CC-P-211
Site plans should be designed to create pedestrian-oriented neighborhoods that follow these guidelines: (a) Buildings should be oriented to the street; (b) Garages and parking areas should be screened and/or located at the side or rear of properties wherever possible; and (c) Landscaping, sidewalk conditions, and other streetscape elements should be improved during rehabilitation and new construction.
Not Applicable. Subject to the Community Development Director’s, the Commission’s, and/or the Council’s interpretation (Section 22.44.020, DBMC), the referenced
policy has been interpreted by the Department to apply only to residential neighborhoods.
CC-P-261
Establish reduced minimum commercial parking requirements for all development within new mixed-use land use designations. Reduced parking requirements
should be supported by proximity to transit, shared parking, and technologies that, once mainstreamed, would reduce the need for conventional parking layouts.
Not Applicable. Although a “shared-parking” permit is included as a project component, because the 2021
Proposed Revised BCBP is not a “mixed-use development,” the policy is not applicable thereto.
CC-P-291
Promote the revitalization of existing commercial centers by encouraging property owners to maintain and improve the appearance of individual buildings and commercial centers through building façade improvements, landscaping, and
pedestrian improvements.
Not Applicable. Notwithstanding the notation in Figure 3-1 (Urban Design Framework) of the 2040 General Plan/CAP, neither the 2019 Approved BCBP nor the 2021 Proposed Revised BCBP constitutes an “existing commercial center.”

CR-P-571 Develop incentives to encourage carpooling, such as preferential parking for high-occupancy vehicles.
CR-P-581 Encourage public schools to improve parking and loading facilities to minimize congestion and delays on the local circulation system. Not Applicable. The project site is not a “public school” facility.
CR-P-671
Ensure that trucks do not interfere with cyclist or pedestrian activity by: (a) Incorporating off-street or buffered bike lanes and walking paths where truck routes overlap with bicycle routes or streets with heavy pedestrian traffic; and (b) Designing driveways and curb cuts to avoid maneuvering on sidewalks or in street traffic, while also facilitating the safe and efficient movement of trucks.
Potentially Inconsistent. Figure 4.2 (Proposed Bicycle Network) of the 2040 General Plan/CAP identified that segment of Brea Canyon Road extending from the City limits to the Pomona Freeway as a “Class IV” (Protected Bike Lane), defined, in part, as “bikeways for the exclusive use of bicycles that are physically separated from vehicle traffic.” Absent the inclusion of a “protected bike lane,” the 2021 Proposed Revised BCBP potentially forecloses local plans for planned bicycle network improvements along Brea Canyon Road.

Based, in part, on that analysis, it is the Department’s preliminary finding that the 2021
Proposed Revised BCBP is in substantial conformance/compliance and is compatible with
the preponderance of the policies, standards, and criteria outlined in the 2040 CAP.39
In addition to those PMMs presented in the 2040 General Plan/CAP/FPEIR relating, directly
or indirectly to those policy directives contained in the 2040 CAP, serving as a “project review
checklist,” based on the Department’s review of the most recent development plans (G/A/A,
September 8, 2021), presented in Table A-5 (2021 Proposed Revised BCBP – 2040 Climate
Action Plan GHG Reduction Measures [September 8, 2021]) is a listing of those “potential
project-level GHG reduction measures” included in the 2040 CAP (Appendix D). “GHG
reduction measures” are neither mandatory obligations nor “mitigation measures” under
CEQA. Those measures are not, therefore, subject to those mitigation reporting and
monitoring obligations outlined in Section 15097 of the State CEQA Guidelines.
Unlike the goals and policies presented in the 2040 General Plan, the “GHG reduction
measures” contained in the 2040 CAP are not policy directives but serve as a partial listing
of a broader range of voluntary measures that can be implemented by project proponents to
reduce project-level GHG emissions. As non-mandatory measures, with regards to the 2021
Proposed Revised BCBP, each of the identified measures presented in Table A-5 (2021
Proposed Revised BCBP – 2040 Climate Action Plan GHG Reduction Measures [September
8, 2021]) are categorized as being “incorporated,” “not incorporated,” or “not applicable.”
Pursuant to Section 15183.5(b) of the State CEQA Guidelines, “a lead agency may
determine that a project’s incremental contribution to a cumulative effect is not cumulatively
considerable if the project complies with the requirements in a previously adopted plan or
mitigation program under specified circumstances.” In the context of Section 15183.5(b) of
the State CEQA Guidelines, the 2040 CAP constitutes a “previously adopted plan or
mitigation program.” If the 2021 Proposed Revised BCBP is deemed to be in compliance
therewith, cumulative global climate change impacts constitute a less-than-significant
environmental effect under CEQA and are not further addressed herein.

40/ A recent study found that “fast-food” workplace transmission of COVID-19 was likely a significant, ongoing
contributor to the spread of the disease throughout California during the last year of the pandemic, particularly among
the workers of color who make up the vast majority of the State’s “fast-food” workforce (Physicians for Social
Responsibility-Los Angeles, COVID-19 Hazards Among California Fast-Food Workers, April 19, 2021). An additional
study reported: “Fast-food workers and their communities face a disproportionate risk of COVID-19 transmission and
its negative impacts. . .Between their sheer number and high customer volume, fast-food restaurants pose a particular
risk of widespread COVID-19 transmission” (Los Angeles County Department of Public Health, The Fast-Food Industry
and COVID-19 in Los Angeles, March 2021). Because they represent potential social impacts, potential workplace
“hazards,” attributable to COVID-19 and other infectious diseases, including those associated with the 2021 Proposed
Revised BCBP’s uses, design, and operations, are not further addressed herein.

(f) Impair implementation of or physically interfere
with an adopted emergency response plan or
emergency evacuation plan?
(g) Expose people or structures, either directly or

death involving wildland fires?
Preliminary Determination: Less-than-Significant Impact
Findings of Fact: The preponderance of issues raised in the City’s environmental checklist
(Appendix G, State CEQA Guidelines) relates to presence, handling, and disposal of
hazardous materials and wastes, specifically: (1) the routine transport, use or disposal of
hazardous materials; (2) the creation a significant hazard to the public or the environment
through reasonably foreseeable upset and accident conditions involving the release of
hazardous materials into the environment; (3) the emission of hazardous emissions or
handling of hazardous or acutely hazardous materials, substances, or waste within one-
quarter mile of an existing or proposed school; (4) the project’s inclusion on a Cortese-listed
property; (5) the project’s location within an airport land-use plan; and (6) the project’s
potential to impair implementation of an emergency response plan. With the exception
thereof, reference to specific hazards is limited to wildfires.
Although not potentially germane to this topical issue, proposed changes to the nature of
allowable on-site uses and changes to the approved improvements to the central median
along Brea Canyon Road (allowing left turning ingress and egress to the project site) may
potentially alter or otherwise affect previously disclosed traffic-related hazards, including the
potential severity thereof. Potential traffic-related issues relating to ingress and egress and
internal circulation are separately addressed in Section 3.17 (Transportation) herein.

Hazards and hazardous materials/wastes are separately addressed below.
Hazards. Relative to identified hazards, no project-level mitigation measures were
identified in the 2019 Approved BCBP/MND or adopted by the Council in Resolution
No. 2019-40 (November 19, 2019). None of the program-level mitigation measures
included in the 2040 General Plan/CAP/FPEIR/MND and adopted by the Council
(Resolution No. 2019-43, December 17, 2019), appear directly relevant to the 2021
Proposed Revised BCBP.
In 2015, the California Supreme Court (California Building Industry Association v. Bay
Area Air Quality Management District) ruled that CEQA does not generally require
consideration of the effects of existing environmental conditions on a project’s future
users or residents but does mandate the analysis of how a project may exacerbate
existing environmental hazards. In that ruling, the Supreme Court held:
With this holding in mind, we must distinguish between requirements that
consider the environment’s effects on a project and those that contemplate
the project’s impacts on the existing environment. The former, in light of our
analysis of Section 21083 and other relevant language in CEQA, are invalid.
The latter, however, are valid and entirely consistent with CEQA’s concerns
about environmental protection, public health, and deliberation. Moreover, and
consistent with CEQA’s general rule, we note that the statute does not
proscribe consideration of existing conditions. In fact, CEQA calls upon an
agency to evaluate existing conditions in order to assess whether a project
could exacerbate hazards that are already present. . .Indeed, the statutory
language emphasizes how the analysis of a project’s potential to exacerbate
existing conditions is not an exception to, but instead a consequence of,
CEQA’s core requirement that an agency evaluate a project’s impact on the
environment.
Under certain circumstances (e.g., preparation of an EIR), CEQA directs the Lead
Agency to ascertain to what extent, if any, a proposed project exacerbates existing
environmental hazards. Referencing Section 15126.2(a) of the State CEQA Guidelines:
The EIR shall also analyze any significant environmental effects the project
might cause or risk exacerbating by bringing development and people into the
area affected. For example, the EIR should evaluate any potentially significant
direct, indirect, or cumulative environmental impacts of locating development
in areas susceptible to hazardous conditions (e.g., floodplains, coastlines,
wildfire risk areas), including both short-term and long-term conditions, as
identified in authoritative hazard maps, risk assessments or in land use plans
addressing such hazards areas.
A broad array of potential environmental hazards (e.g., hydrology and geology) were
previously addressed in the 2019 Approved BCBP/MND. To avoid redundancy,
potential wildfire hazards are separately addressed in Section 3.20 (Wildfires) herein.
♦ Hazardous Materials/Wastes. Relative to hazardous materials, no project-level
mitigation measures were identified in the 2019 Approved BCBP/MND or adopted by
the Council in Resolution No. 2019-40 (November 19, 2019). None of the program-
level mitigation measures included in the 2040 General Plan/CAP/FPEIR/MND and

adopted by the Council (Resolution No. 2019-43, December 17, 2019), appear directly
relevant to the 2021 Proposed Revised BCBP.
As described in the 2019 Approved BCBP/MND, in order to assess the presence or
potential presence of hazardous materials and petroleum products on the project site,
the Applicant submitted a “Phase I Environmental Assessment Report – 850 Brea
Canyon Road (APN 8719-013-017), Walnut, CA 91789” (Robin Environmental
Management, January 26, 2018) (2019 Approved BCBP/ESA). The 2019 Approved
BCBP/ESA examined all on-site areas but did not address off-site areas associated
with the 2019 Approved BCBP and 2021 Proposed Revised BCBP (e.g., Caltrans right-
of-way). As indicated therein:
As a result of the site reconnaissance, review of federal, state, local reported
environmental information regarding the said facilities obtained via computer
search, this assessment identified no evidence of recognized environmental
conditions, by practices at the subject property and its immediate neighbors
that could significantly impact the subject property. No Phase II subsurface
investigation is recommended for the subject site.41
Subsequent to the preparation of that 2019 Approved BCBP/ESA, no actions have
been initiated either by the Applicant or by others that would result in the introduction
of actionable levels of hazardous materials or wastes or petroleum products on or near
the project site. As a result, the information, analysis, and findings presented in that
2019 Approved BCBP/ESA remain relevant to the 2021 Proposed Revised BCBP.
As indicated therein and as described in the 2019 Approved BCBP/MND, the project
site is not identified as a Cortese-listed property. Additionally, the project site is not
located within the boundaries of an airport land-use plan or within two miles of a public
airport or public use airport. Relative to emergency response plans, County-designated
“disaster routes” in the general project area include the Pomona (SR-60) Freeway, Brea
Canyon Road, Valley Boulevard, and Colima Road/Golden Springs Road. Based on
proposed improvements to Brea Canyon Road and to the Brea Canyon Road/Lycoming
Street intersection, multi-jurisdictional disaster response efforts would be enhanced.
Although the project site is located within one-quarter mile of an existing school
(Discovery World Preschool and Private Elementary School, 801 Brea Canyon Road,
Diamond Bar), with the exception of cleaning products and associated household
hazardous wastes, the 2021 Proposed Revised BCBP neither includes the routine
transport, use or disposal of hazardous materials nor the creation a significant hazard
to the public or the environment through reasonably foreseeable upset and accident
conditions involving the release of hazardous materials, hazardous wastes, or
petroleum products into the environment.
The 2021 Proposed Revised BCBP includes the elimination, redesign, and/or
reconfiguration of the previously approved 8,900 GSF “medical office” building (“Parcel
2”) and the incorporation of a proposed 6,500 GSF “retail/restaurant” (“QSR-1”) building
thereupon. As a result, the 2021 Proposed Revised BCBP will likely reduce the
potential presence of “medical wastes” (including biohazardous wastes) and increase

the presence of non-hazardous organic wastes, green wastes, food wastes, and food-
soiled paper, including the “food packaging”42 materials associated therewith.
With the possible exception of styrene and perfluorinated and polyfluorinated alkyl
substances (PFAS),43 the introduction of retail and/or restaurant-related uses (in lieu of
medical office space) is neither anticipated to result in the introduction of any use-
specific hazardous materials and/or hazardous wastes adversely affecting on-site
users, off-site receptors, or the environment at large.
Although not manufactured on the project site, styrene, used to manufacture
polystyrene products, is identified by the State as a human carcinogen under
Proposition 65 chemicals. Styrene, typically in the form of polystyrene foam containers,
may be present in packaging material routinely associated with restaurant-related uses.
The State advises that individuals limit consumption of hot food and beverages from
polystyrene containers (e.g., small amounts of styrene can be transferred to some food
from polystyrene-based food-contact items, such as drinking cups, plates, and other
containers).44
Polystyrene foam food and beverage service ware is a distinctive litter concern
because it is lightweight, easily blown into streets and waterways, and floats in water.
It also breaks apart easily into small pieces, is difficult to collect, and is often mistaken
as food by birds, fish, and wildlife.
Assembly Bill (AB) 1200 (Plant-Based Food Packaging: Cookware: Hazardous
Chemicals), as signed by the Governor on October 5, 2021, added Chapter 15
(commencing with Section 109000) to Part 3 of Division 104 of the H&SC and,
beginning on January 1, 2023: (1) prohibits any person from distributing, selling, or
offering for sale in the State any food packaging that contains regulated perfluoroalkyl
and polyfluoroalkyl substances (PFAS); and (2) requires manufacturers to use the least
toxic alternative when replacing regulated PFAS in food packaging to comply with this
requirement.
The proposed “retail/restaurant” uses are not anticipated to be operational prior to
January 1, 2023. Compliance with the provisions of AB 1200 will reduce potential
PFAS-related hazards to a less-than-significant level.
The construction and operation of the 2021 Proposed Revised BCBP will have less-than-
significant hazards and hazardous materials impacts under CEQA.
42/ Assembly Bill (AB) 1200 (Plant-Based Food Packaging: Cookware: Hazardous Chemicals), as signed
by the Governor on October 5, 2021, added Chapter 15 (commencing with Section 109000) to Part 3 of Division 104
of the H&SC defines “food packaging,” in part, to mean a nondurable package, packaging component, or food service
ware that is comprised, in substantial part, of paper, paperboard, or other materials originally derived from plant fibers.
“Regulated perfluoroalkyl and polyfluoroalkyl substances or PFAS” are defined therein to mean either of the following:
(1) PFAS that a manufacturer has intentionally added to a product and that have a functional or technical effect in the
product, including the PFAS components of intentionally added chemicals and PFAS that are intentional breakdown
products of an added chemical that also have a functional or technical effect in the product; and (2) The presence of
PFAS in a product or product component at or above 100 parts per million, as measured in total organic fluorine.
43/ “PFAS” are defined to mean a class of fluorinated organic chemicals containing at least one fully fluorinated
carbon atom

amended by Order No R4-2006-0074 on September 14, 2006. On November 8, 2012,
superseding “Order No. 01-182,” as amended, the LARWQCB adopted “Order No. R4-2012-

Long Beach MS4” (2021 MS4 Permit). The 2021 MS4 Permit became effective on
September 11, 2021 and expiring on September 11, 2026. “Order No. R4-2012-0175” is not
retroactive and remains valid while it is still in effect.
“Order No. R4-2012-0175” serves to implement the federal Phase I NPDES Stormwater
Program requirements, including the following three fundamental elements: (1) a
requirement to effectively prohibit non-stormwater discharges through the MS4, (2)
requirements to implement controls to reduce the discharge of pollutants in stormwater to
the maximum extent practicable (MEP),45 and (3) other provisions the LARWQCB has
determined appropriate for the control of such pollutants. The 2021 MS4 Permit’s main
purpose is to implement effective pollution prevention programs to reduce the discharge of
pollutants from the MS4 to protect receiving waters and their beneficial uses.
The 2021 MS4 Permit serves as a system-wide general NPDES permit for MS4 storm water
and non-storm water discharges within the coastal watersheds of the County (receiving
waters) under which the Los Angeles County Flood Control District (LACFCD),46 the County,
and 86 incorporated cities (including the City of Diamond Bar and excluding the City of Long
Beach) collectively constitute the “Permittees”47
Pursuant to Section 13263(a) of the California Water Code (CWC), the requirements of that
order implement the LARWQCB’s “Water Quality Control Plan, Los Angeles Basin” (1994)
(Basin Plan).48,49 The project site is located in the San Gabriel Valley Basin Groundwater
Basin. The San Gabriel Valley Groundwater Basin is not a critically over drafted basin. No
Sustainable Groundwater Management Plan has been adopted for that basin.
For certain new development and redevelopment projects, including the 2021 Proposed
Revised BCBP, the 2021 MS4 Permit stipulates that all Permittees implement a “planning
and land development program” (Part VIII.F) in order to: (1) control pollutants, pollutant
loads, and runoff volume emanating from the project site by (a) minimizing the impervious
surface area and (b) controlling runoff from impervious surfaces through infiltration,
bioretention and/or rainfall harvest and use; and (2) unless deemed infeasible, retain, on the
project site, the “Stormwater Quality Design Volume” (SWQDv) from a design storm event,
45/ Municipalities are responsible for reducing the discharge of pollutants in storm water to the maximum extent
practicable (MEP). This means choosing effective Best Management Practices (BMPs) and rejecting otherwise
applicable BMPs only where other more effective BMPs would serve a similar purpose, would not be technically
feasible, or where the cost would be prohibitive.
46/ The Los Angeles County Department of Public Works (LACDPW) manages and maintains flood control
facilities within the major rivers and channels throughout the County. The LACDPW’s Flood Maintenance Division
maintains only those flood control facilities that are part of the County-maintained flood control system and provides no
review, management, or on-going maintenance of private facilities.
47/ A federal appellate court has noted: “In the [Los Angeles County Flood Control] District, stormwater runoff is
collected by thousands of storm drains located in each municipality and channeled to a storm sewer system. The
municipalities in the District operate MS4s to collect and channel stormwater. The County also operates an MS4s for
certain unincorporated areas. Unlike a sanitary sewer system, which transports municipal sewage for treatment at a
wastewater facility, or a combined sewer system, which transports sewage and stormwater for treatment, MS4s contain
and convey only untreated stormwater. In the County, municipal MS4s are ‘highly interconnected’ because the District
allows each municipality to connect its storm drains to the District’s extensive flood-control and storm-sewer
infrastructure. That infrastructure includes 500 miles of open channels and 2,800 miles of storm drains. The length of
the MS4 system and the locations of all storm drain connections are not known exactly because a comprehensive map
of the storm drain system does not exist” (Natural Resource Defense Council v. County of Los Angeles [2011]).
48/ California Regional Water Quality Control Board, Los Angeles Region, Water Quality Control Plan, Los
Angeles Region, 1994, as revised.
49/ A summary of regulatory provisions of the Basin Plan is codified in Sections 3930 et seq. in Title 23 (Waters),
Division 4 (Regional Water Quality Control Boards), Chapter 1 (Water Quality Control Plans, Policies, and Guidelines),
Article 4 (Los Angeles Basin), California Code of Regulations.

The general development footprint of the 2019 Approved BCBP and 2021 Proposed Revised
BCBP projects are similar. Both projects call for the same number of buildings, in the same
general locations, and at the same proposed heights. With the exception of the City’s
adoption of the 2019 CBC and 2019 CalGreen (Ordinance No. 04[2019], December 3, 2019)
and the LARWQCB’s adoption of “Order No. R4-2021-0105” (NPDES Permit No.
CAS004004, July 23, 2021), the initiation of on-site grading activities, no changes to
localized and/or regional hydrology have occurred following the adoption of the 2019
Approved BCBP/MND.
As part of the 2021 Development Application, the Applicant submitted an updated
“Hydrology, Hydraulic & LID Calculations for Brea Canyon Business Park, 850 S. Brea
Canyon Road, Diamond Bar, CA 91789 (Plotnik & Associates, September 6, 2021). That
technical report includes the 2021 Proposed Revised BCBP’s “low impact development plan”
(2021 Proposed Revised BCBP/LID), as submitted in compliance with and meeting the
requirements set forth in the California Regional Water Quality Control Board, Los Angeles
Region (LARWQCB) “Order No. R4-2012-0175” (NPDES Permit No. CAS004001).
As indicated in the 2019 Approved BCBP/MND, with regards to the 2019 Approved BCBP,
approximately 70 percent of the project site will be covered with impervious surfaces. With
regards to the 2021 Proposed Revised BCBP, the proposed impervious areas will also cover
approximately 70 percent of the project site. Because the amount of impervious surfaces will
not increase, the 2021 Proposed Revised BCBP will not substantially decrease groundwater
supplies or interfere substantially with groundwater recharge. Similarly, the 2021 Proposed
Revised BCBP will not increase the quantity or quality of stormwater discharged from the
project site.
Applicable to both the 2019 Approved BCBP and 2021 Proposed Revised BCBP, storm
drain runoff from impervious areas will be directed to surface gutters leading to catch basins
and underground storm drain piping. Storm drain piping will direct the runoff to underground
infiltration chambers sized to accommodate the SWQDv. Once the infiltration chambers are
full, the flow will bypass the chambers and flow into the existing County flood control channel
(PD 1445). All downstream drainage conveyance systems are fully improved and have been
designed to handle runoff to allowable flows dictated by the County. Drainage systems
discharge to the Pacific Ocean.
As per LACDPW standards, runoff into that channel is restricted to 1.78 cubic feet/second
(cfs) per acre. The drainage area consists of the approximately 5.69-acre project site51 plus
an additional 0.56-acre Caltrans’s landscaped slope area which drains onto the site. The
project site is divided into 9 drainage areas (Areas A-1 through A-6, B, C, and D). Each of
those drainage areas discharge to the County flood control channel. The allowable discharge

(Q50) thereto totals 11.13 cfs (6.25 acres x 1.78 cfs/acre). The unmitigated 50-year
recurrence interval peak flow to that channel is 18.21 cfs and, therefore, exceed that
allowable volume.
In response thereto, with regards to the 2019 Approved BCBP, the following “conditions of
approval” were imposed by the Council (Resolution No. 2019-42):
♦ A Storm Water Pollution Prevention Plan (SWPPP) shall be submitted and
approved by the City, uploaded to the State’s SMARTS system, and a WDID [Water
Discharge Identification] number shall be acquired from the California Water Board
prior to the issuance of construction permits.
♦ The applicant shall comply with Low Impact Development (LID) requirements to the
satisfaction of the City Engineer. The LID Plan will be required to comply with the
2012 MS4 Permit. The LID Plan shall be approved prior to grading permit issuance
and/or building permit issuance for new structures.
♦ Detailed drainage system information of the lot shall be submitted. All
drainage/runoff from the development shall be conveyed from the site to the natural
drainage course. No on-site drainage shall be conveyed to adjacent parcels, unless
that is the natural drainage course.
♦ Prior to the issuance of a grading permit, a complete hydrology and hydraulic study
shall be prepared by a City Engineer registered in the State of California to the
satisfaction of the City Engineer.
♦ All drainage improvements necessary for dewatering and protecting the subdivided
properties shall be installed prior to issuance of building permits, for construction
upon any parcel that may be subject to drainage flows entering, leaving, or within
a parcel relative to which a building permit is requested.
Compliance with the 2021 MS4 Permit, applicable County and City standards, and the
adopted “conditions of approval” imposed on the 2019 Approved BCBP relating to hydrology
and water quality, including the preparation of a Storm Water Pollution Prevention Plan
(SWPPP) and the incorporation of appropriate Best Management Practices (BMPs), will
ensure that potential water quality impacts attributable to the construction and
implementation of the 2021 Proposed Revised BCBP will remain at a less-than-significant
level under CEQA.

(a) Physically divide an established community?
(b) Cause a significant environmental impact due to

Preliminary Determination: No Impact
Findings of Fact: Relative to land use and planning, no project-level mitigation measures
were identified in the 2019 Approved BCBP/MND or adopted by the Council in Resolution
No. 2019-40 (November 19, 2019). None of the PMMs included in the 2040 General
Plan/CAP/FPEIR/MND and adopted by the Council (Resolution No. 2019-43, December 17,
2019), appear directly relevant to the 2021 Proposed Revised BCBP.
When comparing the 2019 Approved BCBP and 2021 Proposed Revised BCBP, the
proposed changes to the development plan include, but may not be limited to:
♦ Although the 2021 Proposed Revised BCBP remains a 4-lot subdivision, the size and
configuration of those parcels has been revised, amended, updated, expanded, and/or
modified in the revised site plan.
♦ The 1-story 8,900 GSF multitenant “medical office” building (“Parcel 2”) included in the
2019 Approved BCBP would be replaced with a 6,500 GSF single or multitenant
“retail/restaurant” (“QSR-1”) building (“Parcel 2”), including, but not limited to, a “fast-
food restaurant” (with “drive-thru”) and one or more additional unspecified “restaurants”
and/or “retail” uses.
That structure has been identified by the Applicant at the “QSR-1” building. Although
alternatively identified by the Applicant as “quick service retail”52 or “quick service
restaurant,”53 the acronym “QSR” is typically associated with the food industry’s
restaurant categorization of “quick-service restaurants” (e.g., “fast-food restaurants”).
Unless the word “retail” is interpreted to include all manners of restaurants, defining the
“QSR-1” building as “quick service retail” building may, therefore, be a misnomer.
♦ The total gross square footage of the proposed “hotel” has increased by approximately
2,785 GSF and the number of guest rooms has increased from 109 to 124 rooms.
♦ The proposed hotel modification includes extending the front of the hotel by
approximately two feet in certain areas.

♦ The total gross leasable area (GLA) of the entire project has increased by an estimated
385 gross square feet (GSF) from 118,471 gross square feet to 118,856 GSF.
♦ Although no operational parameters have been identified by the Applicant, by changing
the proposed land use on “Parcel 2” from “medical office” to “retail/restaurant,” the
anticipated hours of operation associated with the “restaurant” and the “drive-thru” lane
would be expected to expand to include additional evening and weekend hours. If
different, the hours of operation of the indoor areas associated with the “restaurant”
and the “outdoor dining area” may differ, such that the hours that the “drive-thru” and
the “outdoor dining area” operate may extend beyond those associated with the
provision of other indoor restaurant-related services.
♦ Compared to the previously approved “medical office” building (“Parcel 2”), increased
exterior lighting and signage is associated with the proposed “retail/restaurant” uses.
♦ The proposed “retail/restaurant” uses (“Parcel 2”) include the introduction and
operation of both one or more unspecified outdoor speakers and one or more
illuminated menu board associated with the operation of the “drive-thru” lane.
♦ “Fast-food restaurants” and other “restaurants” typically generate odors not routinely
associated with “office” uses.
♦ The inclusion of “outdoor dining” opportunities will likely result in a greater number of
people congregating and conversing in exterior on-site areas.
♦ The operation of the “drive thru” will introduce queuing vehicles and associated engine
and other amplified noise (e.g., radios and sound systems) within close proximity to
proximal residences.
A lead agency conducting environmental review of a project must consider whether the
project would “conflict with any applicable land use plan, policy, or regulation adopted for
the purpose of avoiding or mitigating an environmental effect” (Appendix G[XI][b], State
CEQA Guidelines). “Land use plans, policies, and regulations” can be construed as
inclusive of both general plan and zoning ordinances. Both policy-based and regulatory
documents are separately addressed below.
♦ 2040 General Plan/CAP. With regards to the 2021 Proposed Revised BCBP’s
consistency with the 2040 General Plan/CAP, based on the Department’s review of the
most recent development plans (G/A/A, September 8, 2021), a policy-based
consistency analysis is presented in parts in Table A-4 (Preliminary Consistency
Analysis – Applicable 2040 Climate Action Plan Goals and Policies [September 8,
2021]) and Table A-6 (2021 Proposed Revised BCBP Preliminary Consistency
Analysis – Applicable 2040 General Plan Goals and Policies [September 8, 2021]).
Although certain goals and objectives appear to address potential environmental
effects, based on the precise nature of a proposed project, not all such goals and
policies are applicable to all development-related activities undertaken within the City.
Those goals and policies that do not appear to avoid or mitigate a potential
environmental effect or have been preliminarily deemed by the Department to be either
“not applicable” or “not relevant” to the 2021 Proposed Revised BCBP, including those
policies that cannot be reasonably implemented at the project level, are not cited
therein. As such, the listing presented is not intended to be inclusive of the totality of
goals and objectives included in the 2040 General Plan/CAP.

No. Policy Application
Land Use and Planning
LU-G-1 Maintain a balanced mix of land uses, including employment, residential, retail, and open space, including open space devoted to the preservation of natural resources, to support a vibrant community and Diamond Bar’s quality of life.
Consistent. The 2021 Proposed Revised BCBP includes a “mix of land uses.”
LU-G-3 In areas planned to accommodate new growth, ensure quality design that makes a positive contribution to the character of Diamond Bar. Consistent. The 2021 Proposed Revised BCBP is subject to the City’s “development review” process.
LU-G-5 Manage development in a manner consistent with the capabilities of the City to provide public services and facilities effectively. Consistent. The project site is adequately serviced by “public services and facilities.”
LU-P-1 Ensure that the scale and massing of new development provides sensitive transitions or design techniques in building height, bulk, and landscaping to minimize impacts on adjacent, less intensive uses, particularly residential uses.
Consistent. The 2021 Proposed Revised BCBP seeks no deviation from applicable building height, bulk, and landscaping standards.
LU-P-4 Monitor and evaluate potential impacts of proposed adjacent, local, and regional developments to anticipate and require mitigation to the greatest extent feasible to reduce land use, circulation, and economic impacts on Diamond Bar.
Consistent. No significant unmitigable “land use,
circulation, and economic impacts” result from the approval, construction, and operation of the 2021 Proposed Revised BCBP.
LU-P-5 Ensure that adequate public services, facilities, and infrastructure are available or provided to support new development, including water, wastewater, stormwater, solid waste, transportation, public safety, and parks.
Consistent. “Adequate public services, facilities, and infrastructure” are available to serve the 2021 Proposed Revised BCBP.
LU-P-6 When appropriate, require new development to pay its fair share of the public facilities and off-site improvements needed to serve the proposed use. Consistent. The 2021 Proposed Revised BCBP includes the payment of “fair share” impact fees.
LU-P-7 As larger vacant or underutilized sites within the built environment are developed or redeveloped, maximize multimodal accessibility with appropriately designed street networks, and walkable block sizes scaled to proposed uses.
Potentially Inconsistent. The 2019 Approved BCBP was not subject to the 2040 General Plan/CAP and no comparable policy existed therein. The 2021 Proposed Revised BCBP potentially forecloses local plans for planned bicycle network improvements.
Commercial, Office, and Industrial
LU-G-8 Promote the development of distinct, well-designed commercial centers that serve neighborhood residents, community members, and/or the region at large and help maintain economic vitality.
Consistent. The 2021 Proposed Revised BCBP will “help maintain economic vitality.”
LU-P-12 Ensure that commercial uses and shopping centers are designed in a manner compatible with adjacent residential areas in terms of traffic and noise impacts, building scale, and appropriate transitions and buffers.
Consistent. The introduction of a “fast-food restaurant”
(with “drive-thru”) and an “outdoor dining area” introduces a variety of new noise sources adjacent to and potentially perceptible to those sensitive receptors; however, anticipated noise impacts are projected to be below existing ambient noise levels associated with the Pomona (SR-60) Freeway.
Economic Development
ED-G-1 Prioritize infill development opportunities and the reuse of existing vacant commercial space to grow the city’s base of residents and employment to ensure long-term fiscal sustainability and promote conservation of natural open space.
Consistent. The 2021 Proposed Revised BCBP represents a “infill development opportunity” that expands employment and promotes long-term fiscal sustainability.
ED-G-2 Provide for the development of jobs and commercial uses within Diamond Bar to reduce residents’ commutes, and to encourage residents to shop and dine locally. Consistent. The 2021 Proposed Revised BCBP would create new jobs and commercial opportunities.
Community-Serving Uses
CC-G-6 Encourage high-quality, human-scaled design and development that respects the surrounding built environment while offering a diversity of building types.
Consistent. So as to create the greatest separation distance, the proposed hotel expansion is located on the most southern portion of the project site.
City Identity
CC-P-5 Establish a landscaping palette made up of native, drought-tolerant plants and stormwater management systems with a view to enhancing beautification and sustainable landscaping practices.
Consistent. The 2021 Proposed Revised BCBP incorporates both drought-tolerant landscaping and an integrated stormwater management system.

City Identity (Continued)
CC-P-6
Prioritize sustainability in site design. When incorporating on-site stormwater management through the use of bioswales, rain gardens, permeable pavement,
and/or other available low-impact development technologies, require such features to be aesthetically integrated into the site design
Consistent. The 2021 Proposed Revised BCBP/LID is compliant with applicable City policies relating to sustainable site design.
Streetscapes and Building to Street Interface
CC-P-10
Maintain an open relationship between buildings and the street edge, avoiding
fencing and significant landscape barriers but incorporating street trees and other landscaping where possible.
Consistent. The 2021 Proposed Revised BCBP does not
include a perimeter wall along its Brea Canyon Road frontage.
Site Planning and Parking
CC-P-25 Encourage the design of shared parking for commercial and office uses where possible. Consistent. The 2021 Proposed Revised BCBP is subject to receipt of a “shared-parking” permit.
Building Massing and Design
CC-P-28 Ensure that new development does not cast significant shadows over existing development. Require detailed shadow studies as part of development review where appropriate.
Consistent. A “shade and shadow” analysis was presented in the 2019 Approved BCBP/MND and
demonstrated “no significant shadows over existing development.” The 2021 Proposed Revised BCBP neither increases the height of any proposed structures nor relocated any structures closer to any “existing development.”
CC-P-35
Ensure the protection of views of hillsides and ridges from public streets, parks, trails, and community facilities by requiring a visual impact analysis for new development that identifies potential impacts to visual resources as well as feasible measures to mitigate any potential impacts.
Consistent. Because the site abuts the Pomona (SR-60) Freeway, no substantial “views of hillsides and ridges
from public streets” presently exist. Because no significant aesthetic impacts have been identified, no “visual impact analysis” is either required or warranted.
Transportation Network and Street Design
CR-G-1
Improve the operating efficiency of the transportation system by reducing vehicle
travel demand and providing opportunities for other modes of travel. Before approving roadway improvements that focus on increasing vehicle capacity, consider alternatives that reduce vehicle volumes and prioritize projects that would reduce single-occupancy vehicle use and greenhouse gas emissions.
Potentially Inconsistent. The 2019 Approved BCBP was
not subject to the 2040 General Plan/CAP and no comparable policy existed therein. The 2021 Proposed Revised BCBP potentially forecloses local plans for planned bicycle network improvements.
CR-P-5
Necessary transportation improvements should be in place, or otherwise guaranteed to be installed in a timely manner, before or concurrent with new development. In evaluating whether a transportation improvement is necessary, consider alternatives to the improvement consistent with CR-G-1, and the extent to which the improvement will offset the traffic impacts generated by proposed and
expected development.
Consistent. The 2021 Proposed Revised BCBP/TIA identifies relevant project-specific transportation improvements associated with the proposed project. The Applicant has committed to the payment of applicable
“fair-share contributions” thereto.
CR-P-6 Continue to implement congestion mitigation measures to ensure that new projects do not significantly increase local City congestion based on defined level of service (LOS) standards.
CR-P-7
Support the development of City street design standards that: (a) Address the needs of different modes according to roadway classification (b) Reduce the potential for conflicts and safety risks between modes; and (c) Support and manage the use of transportation options that will become increasingly popular in
the future, such as TNCs [Transportation Network Companies], AVs [autonomous vehicles], micro-transit (privately operated transit), and other emerging transportation technologies.
Potentially Inconsistent. The 2019 Approved BCBP did not include a “retail/restaurant” use. The 2019 Approved
BCBP was not subject to the 2040 General Plan/CAP and no comparable policies existed therein.
The 2021 Proposed Revised BCBP does not appear to presently accommodate TNC (including “third-party delivery services” and “curbside pick-up) and potentially forecloses local plans for planned bicycle network improvements. CR-P-8
Plan for passenger pick-up / drop-off locations within both public right-of-way and on private properties for AVs, TNCs, and micro-transit to limit traffic disruptions and increase safety by identifying and designating specific locations for pick-ups and drop-offs.

Figure 4.2 (Proposed Bicycle Network) of the 2040 General Plan/CAP identified that
segment of Brea Canyon Road extending from the City limits to the Pomona Freeway
as a “Class IV” (Protected Bike Lane), defined, in part, as “bikeways for the exclusive
use of bicycles that are physically separated from vehicle traffic.” Although no
“protected bike lane” is included in the design of the 2021 Proposed Revised BCBP,
the 2021 Proposed Revised BCBP does include opportunities for on-site bicycle
parking. Implementation would not prohibit continuing bicycle travel along Brea Canyon
Road.
Since not all policies equally relate to all development projects, recognizing that no
public or private project can fully conform to all such public policies, it is the
Department’s preliminary finding that the 2021 Proposed Revised BCBP is in
substantial conformance/compliance and is compatible with the preponderance of the
policies, standards, and criteria presented in the 2040 General Plan/CAP.
♦ Diamond Bar Municipal Code. California courts have given governmental decision-
making bodies broad discretion in interpreting consistency with its own regulations.
Except as potentially noted, the Lead Agency’s approval or conditional approval of
those entitlements requested by the Applicant are intended to ensure consistency
between the 2021 Proposed Revised BCBP and the DBMC.
Chapter 22 (Standards for Specific Land Uses), Title 22 (Development Code) of the
DBMC “provides site planning and development standards for land uses that are
allowed by Article II (Zoning Districts and Allowable Land Uses).” Applicable or
potentially applicable provisions outlined therein include, but may not be limited to:
◊ Section 22.42.050 (Drive-In and Drive-Through Facilities). As specified, in
part, in Section 22.42.050 (Drive-In and Drive-Through Facilities) therein:
o Each drive-through aisle shall be separated from the circulation routes
necessary for ingress or egress from the property, or access to a parking
space.
o The vehicle queuing capacity of the drive-through facility and the design
and location of the ordering and pickup facilities shall be determined by
the [Community Development] director. The applicant shall submit a
circulation study and appropriate documentation addressing the
following issues: (a) Nature of the product or service being offered; (b)
Method by which the order is processed; (c) Time required to serve a
typical customer; (d) Arrival rate of customers; (e) Peak service hour; and
(f) Anticipated vehicular queuing required.54
o Each drive-through aisle shall be appropriately screened with a
combination of landscaping, low walls, and/or berms to prevent headlight
glare from impacting adjacent streets and parking lots; and
o A six-foot-high solid decorative wall shall be constructed on each
property line that is adjoining a residentially zoned or occupied parcel.
The design of the wall and the proposed construction materials shall be
subject to the approval of the director.
54/ With regards to the 2021 Proposed Revised BCBP, notwithstanding the inclusion of a proposed “fast-food

◊ Section 22.42.080 (Outdoor Display and Sales Standards). As specified, in
part, in Section 22.42.080(3) (Outdoor Dining and Seating Area) therein:
o Alcohol beverage sales. Areas in which alcoholic beverages will be
served shall comply with the standards established by the state
department of alcoholic beverage control, and the following standards:
(1) Accessible. The dining area shall be accessible from inside the
restaurant only, unless the director waves this requirement in
circumstances where this is not feasible or practical; (2) Physically
defined. The dining area shall be clearly and physically defined. It shall
be clearly a part of the restaurant serves; and (3) Supervision. The
dining area shall be supervised by a restaurant employee to ensure
compliance with laws regarding on-site consumption of alcoholic
beverages.
o Additional off-street parking. Outdoor dining areas that are not part of
a specific restaurant, but are used in common with several restaurants
or tenants within a commercial center, shall not be required to provide
additional off-street parking for these common outdoor areas.
o Design compatibility. Outdoor dining and seating areas are subject to
compatibility with surrounding uses and a high standard of design quality,
the following standards shall be implemented:
• Entertainment. Outdoor dining and seating areas that provide
dancing, entertainment or amplified music shall require the
preparation of a noise analysis with appropriate mitigation
measures to ensure that noise levels will not exceed those specified
in Chapter 22.28 (Noise Control).
• Separation requirements. Outdoor dining and seating areas shall
be separated from residential uses, at a minimum distance of 200
feet, except in mixed-use projects.
o One-year review required. Minor conditional use permits for outdoor
dining and seating areas are subject to review after one year, at which
time the director shall conduct a study to determine if adverse impacts
have resulted from the use. If none are found, then a permanent
conditional use permit may be granted.
The proposed “outdoor dining and seating area” is located within a 200-foot radius of
the proximal residential uses located to the north and west of the project site. Because
the existing “Farmer Boys Restaurant” (810 Brea Canyon Road, Diamond Bar) is
located in closer proximity to existing residential units located along Lycoming Street,
a precedence exists for the approval of a lesser separation distance. Additionally, a
minimum 6-foot-tall CMB, or equivalent, wall is proposed along the project site’s
northern boundary

delineated on a local general plan, specific plan
or other land use plan?
Preliminary Determination: No Impact
Findings of Fact: Relative to mineral resources, no project-level mitigation measures were
identified in the 2019 Approved BCBP/MND or adopted by the Council (Resolution No. 2019-
40, November 19, 2019). Additionally, none of the program-level mitigation measures

No. 2019-43, December 17, 2019), appear directly relevant to the 2021 Proposed Revised
BCBP.
The 2019 Approved BCBP/MND concluded that no regionally-available or locally-important
mineral resources exist on or near the project site. The development footprint of the 2021
Proposed Revised BCBP is the same as that associated with the 2019 Approved BCBP. As
indicated in Table A-1 (Comparative Limited Development Analysis – 2019 Approved BCBP
and 2021 Proposed Revised BCBP [September 8, 2021]), although a change in authorized
land use is being proposed, the total square footage of all on-site development would
increase by only 385 GSF. Based on the relatively minimal extent of that project-related
increase, the 2021 Proposed Revised BCBP’s potential impacts on mineral resources would
be de minimis.

Preliminary Determination: Less-than-Significant with Mitigation Incorporated
Findings of Fact: Replacing outdated versions thereof, on December 3, 2019 (Ordinance
No. 04[2019]), the Council adopted the 2019 CBC and 2019 CalGreen standards. In
response to potentially significant noise-related impacts attributable to the 2019 Approved
BCBP, as indicated in the 2019 Approved BCBP/MND/MRMP the following project-level
mitigation measures were adopted by the Council. They have been modified as applicable
to reflect the updated versions of the referenced codes. Each of the following project-level
mitigation measures remain applicable to the 2021 Proposed Revised BCBP.
♦ MM-11 (Construction). In accordance with the provisions of the “City of Diamond
Bar Municipal Code,” construction shall be restricted to between the hours of 7:00
AM and 7:00 PM on weekdays and Saturdays. No construction shall occur at any
time on Sundays or on federal holidays. These days and hours shall also apply
to the servicing of equipment and to the delivery or removal of equipment and
materials to or from the site.
♦ MM-12 (Construction). All construction equipment shall be properly maintained
and tuned to minimize noise emissions.
♦ MM-13 (Construction). All equipment shall be fitted with properly operating
mufflers, air intake silencers, and engine shrouds no less effective than originally
equipped.
♦ MM-14 (Construction). During site preparation and paving operations, the
construction contractor shall place temporary noise barriers, in the form of
continuous ¾-inch plywood or hay bales, or similar dense material acceptable to
the Department, along the site perimeter when performing construction operations
within 100 feet of the rear yard areas of any existing residential units located to
the north of the County flood control channel. Such barriers shall be tall enough
to block the line of sight between any proximal residences and the top of the
exhaust stack associated with the on-site use of heavy construction equipment.
♦ MM-15 (Construction). The construction contractor shall specify the use of
electric stationary equipment (e.g., compressors) that can operate off of the power
grid, where feasible. Where infeasible, stationary noise sources (e.g., generators
and compressors) shall be located as far from residential receptor locations as
feasible.
♦ MM-16 (Construction). The construction contractor shall post details of the
project’s construction schedule and the names and telephone numbers of both

Code” (Title 24, Part 11, California Code of Regulations).
♦ MM-20 (Operational). All exterior fittings that enter the structures (e.g., electrical
conduits; heating, ventilation and air conditioning [HVAC] ducts) are to be sealed
with caulk such that the fittings are rendered as air-tight. Any metal duct-work
that is exposed to the exterior environment shall be enclosed and insulated to
avoid noise transference through the ducting.
♦ MM-21 (Operational). The proposed project shall be operated in accordance with
any and all additional conditions as may be set forth by the Department for noise
mitigation.
None of the program-level mitigation measures included in the 2040 General Plan/CAP/

Ground-borne vibrations are typically associated with the use of certain construction
equipment (e.g., pile drivers). No such construction equipment is anticipated for the
construction of the proposed project. No vibration is anticipated as a result of operation of
the 2021 Proposed Revised BCBP. Additionally, the project site is not located in the vicinity
of a private airstrip, an airport land use plan, or within two miles of a public airport or private-
use airport.
The 2021 Proposed Revised BCBP includes, but is not limited to, the replacement of the
previously approved 8,900 GSF multitenant “medical office” building with a 6,500 GSF single
or multitenant “retail/restaurant” (“QSR-1”) building, including the introduction of “drive-thru”
operations, an “outdoor dining area,” a relocated loading zone serving the “retail/restaurant”
(“QSR-1”) building, and extended operational hours. This section analyzes the potential
noise impacts based on those project-related features.
♦ Loading Zone. The 2021 Proposed Revised BCBP includes the design and operation
of a “loading zone” directly adjacent to the northern property line, associated with the
proposed “retail/restaurant” (“QSR-1”) building (“Parcel 2”), adjacent to the proposed
trash receptor location. The nearest residential receptor is separated therefrom by only
the existing 50-foot-wide flood control channel (PD 1445) (Diamond Bar Creek). During
loading activities, as well as trash pick-up operations, noise would be generated by

truck engines, exhaust systems, braking, back-up alarms, drop-down ramps, the
movement of materials and dumpsters, and conversations between parties.
The location of the proposed loading zone and trash area for the “retail/restaurant”
(“QSR-1”) building (“Parcel 2”) closely corresponds to the location of the “Noise
Monitoring Location NR-4,” as presented in the 2019 Approved BCBP/MND. As
described therein:
This noise reading was obtained toward the north end of the project site and
most distant from the local traffic. The selected location was partially shielded
from noise generated along Brea Canyon Road by the presence of the
“Farmer Boys” restaurant located to the west. The reading would be
representative of the noise experienced at the residential units located across
the County flood control channel. The noise meter was placed 5 feet south of
the chain link fence line to the County flood control channel and 90 feet
southeast of the northernmost property line. A 15-minute reading was
obtained from 12:10 PM [July 24, 2019]. In this location, the noise from Brea
Canyon Road, the off ramp, and freeway were all audible and no vehicle
counts were obtained during this noise reading.
The Leq, Lmin, Lmax, L02, L08, L25, and L50 values were recorded to document the
ambient noise at that location. The Leq value is representative of the equivalent noise
level or logarithmic average noise level obtained over the measurement period. The
Lmin and Lmax represent the minimum and maximum root-mean-square noise levels
obtained over a period of 1 second. The L02, L08, L25, and L50 represent the values
exceeded 2, 8, 25, and 50 percent of the time (1, 5, 15, and 30 minutes per hour),
respectively, if the readings were extrapolated out to an hour’s duration. The readings
are summarized in Table A-7 (2021 Proposed Revised BCBP – On-Site Noise Level
Measurements [July 24, 2019]).

1. The Leq represents the equivalent sound level and is the numeric value of a constant level that over the given period of time transmits
the same amount of acoustic energy as the actual time-varying sound level. The L02, L08, L25, and L50 are the levels that are exceeded 2,
8, 25, and 50 percent of the time, respectively. Alternatively, these values represent the noise level that would be exceeded for 1, 5, 15,
and 30 minutes during a 1-hour period. The Lmin and Lmax represent the minimum and maximum root-mean-square noise levels
obtained over a period of 1 second.

Typically, a medium 2-axel truck used to make deliveries can generate a maximum
noise level of 75 dBA at a distance of 50 feet. As indicated in Table A-7 (2021 Proposed
Revised BCBP – On-Site Noise Level Measurements [July 24, 2019]), that level
exceeds existing (2019) ambient conditions at that location.
The maximum noise level indicated is generated by a truck operated by an experienced
driver with typically applied accelerations. Higher noise levels may be generated by the
excessive application of power. Conversely, lower levels may be achieved but would

not be considered representative of nominal truck operations. Truck deliveries to the
“retail/restaurant” (“QSR-1”) building (“Parcel 2”) would generally consist of small trucks
or vans and would not generate excessive noise levels over an extended period of time.
As specified in Section 8.12.740 (Load and Unloading Operations), Title 8 (Health and
Safety) of the DBMC: “Loading, unloading, opening, closing or other handling of
boxes, crates, containers, building materials, garbage cans or similar objects
between the hours of 10:00 p.m. and 6:00 a.m. in such a manner as to cause noise
disturbance is prohibited.” Compliance therewith will effectively ensure that noise
impacts attributable to the use and operation of the loading zone for the proposed
“retail/restaurant” (“QSR-1”) building (“Parcel 2”) remains at a less-than-significant
level under CEQA.
♦ Parking Lot. Typical noise sources associated with parking lots include tire squealing,
doors slamming, car alarms, horns, and engine start-ups. Table A-8 (Maximum
Estimated Noise Levels from Parking Lot Activity) shows maximum instantaneous
noise levels associated with the operation of parking lots. Although these noises occur
for short bursts of time, instantaneous parking lot noise could reach a maximum
estimated 69 dBA at a distance of 50 feet and 67.8 dBA at 60 feet. Noise levels
associated with the parking lot would be expected to fluctuate depending on operating
hours and level of usage.

Although the nearest parking space is located approximately 60 feet from the nearest
residence, most on-site parking is located at a substantially greater distance therefrom.
While the instantaneous maximum sound levels generated by a car door closing,
engine starting up, and vehicle movements on the project site may be periodically
audible to adjacent noise-sensitive receptors, parking lot noises constitute typical noise
sources in urban areas and are, thusly, part of the existing baseline.
Traffic associated with parking lots is typically not of sufficient volume to exceed
community noise standards, which are based on a time-averaged scale, such as the
CNEL. Associated noise would primarily remain on the project site and would be
intermittent. Because the 2021 Proposed Revised BCBP will not place the project’s
parking lot any closer to proximal sensitive receptors than associated with the 2019
Approved BCBP, the resulting noise impact is less than significant under CEQA.
♦ Outdoor Speakers. With regards to the 2021 Proposed Revised BCBP, because the
owner, operator, franchisee, licensee, and/or master leasee for the “retail/restaurant”
(“QSR-1”) building has not been identified, the operator(s) of the “fast-food restaurant”

(with “drive-thru”) and the additional unspecified “restaurants” are not known. Similarly,
except for food-related services, certain operational characteristics associated
therewith have not been specified by the Applicant.
In accordance with Section 22.16.075 (Live Entertainment and Dancing) of the DBMC,
“[l]ive entertainment and dancing is prohibited in bars, cocktail lounges and taverns,
motels, and restaurants.” As defined in Section 22.80.020 (Definitions of Specialized
Terms) of the DBMC:
Any live performance, including but not limited to all forms of music, theatrical
or comedic performance, song, dance, karaoke, or vocal entertainment by a
disc jockey or announcer, participated in by one or more employees,
independent contractors, guests, customers, or any other person or persons.
Does not include ambient or incidental music provided for guests or patrons
by one nonamplified musician or the use of a radio or other electronic playback
device in any establishment, except when utilized by an announcer or "disc
jockey" who at any time provides any form of vocal entertainment for the
purpose of gaining the attention and interest of, or diverting or amusing guests
or patrons, including the announcing of song titles or artists' names [emphasis
added].
The term “amplified music” is deemed by the Department to be synonymous with
“amplified sound.” The two terms are not, however, explicitly defined in the DBMC.
Citing Section of the 22.80.020 of the DBMC, the referenced exclusion does not include
“incidental music” emanating from a “radio or other electronic playback device” (e.g.,
radio tuners, phonographs, tape players, cassette-decks, disc-players, MP3 players,
IPods, and other similar devices having the ability to play broadcast and/or pre-
recorded music and including build-in or removal speakers). The use of those devices
to play a broadcast or a recording of a human voice or a musical instrument can both
replicate and further enhance noise levels as associated with a “live performance”
(including mechanical and electronic amplification of noise emanating from a live
performance, broadcast, or other prerecorded sources).
“Incidential music” is, therefore, authorized when utilized in a fashion incidential to the
restaurant’s use. Associated noise levels are not projected to exceed the City’s exterior
noise standards, would be masked by existing vehicle noises associated with the
Pomona (SR-60) Freeway and Brea Canyon Road, and would, therefore, not constitute
a public nuisance. As such, the resulting noise impact would be less than significant
under CEQA.
♦ Menu Boards. The DBMC’s reference to “amplified music” is not assumed to be
inclusive of any “outdoor sound” associated with outdoor speakers located in the area
of the menu board or speaker post relating to the “drive-thru” ordering menu and
associated only with the placement of food orders from queuing vehicles.
With regards to the 2021 Proposed Revised BCBP: (1) when the “amplified music” is
“incidental” to a restaurant’s operation (e.g., background music), no prohibition on the
use of “electronic playback devices” exists; (2) no allowable sound level, duration,
orientation, or hours are expressly delineated; and (2) no specifications relating to the
installation and operation of outdoor speakers on or in proximity to the proposed

“retail/restaurant” (“QSR-1”) building (“Parcel 2”), or elsewhere, is included in the 2021
Development Application.
The precise location of the outdoor speaker(s) located in the area of the “drive-thru”
ordering menu, including their number and orientation, remain generally undetermined.
As proposed, the menu boards or speaker posts appear to be located and oriented
toward the west of the project site, away from the homes located along Lycoming Street
and Dryander Drive but toward those residential units located to the west of Brea
Canyon Road.
According to the “Drive-Thru Sound Levels from the Menu Board or Speaker Post” (HM
Electronics, May 24, 2010), the typical noise level associated with active “drive-thru”
operations, measured at the speaker post, is 60 dBA Leq at a distance of 16 feet. When
ambient noise levels decrease at night, with the incorporation of an automatic volume
control (AVC) system,55 the adjusted outbound volume can be reduced to 36 dBA at
16 feet.56 With the installation of a AVC or similar sound-reduction system, the noise
levels associated with the “drive-thru” speaker(s) would not exceed the City’s nighttime
noise standard of 45 dBA, as indicated in: (1) Section 22.28.060 (Exterior Noise
Standards) (Table 3-9 [Exterior Noise Standards]) of the DBMC; and (2) Table 7-1
(Community Noise Compatibility Matrix) in the Public Safety Element of the 2040
General Plan.
Because technological solutions exist and are routinely incorporated into the design
and operation of menu boards and accompanying speaker posts and because the
Department retains the ability to regulate the location, orientation, and impose
reasonable control associated therewith, the resulting noise impact is less than
significant under CEQA.
♦ Outdoor Dining. The proposed “outdoor dining and seating area” is located at a
distance of approximately 104 feet from proximal residential receptors, representing a
separation distance that is substantially less than the 200-foot minimum setback
specified under Section 22.42.080(d) of the DBMC.
With regards to the “outdoor dining area,” assuming a City-imposed prohibition on the
installation and operation of additional exterior-mounted outdoor speakers, excluding
both “incidential music” and noise associated with and emanating from motor vehicles,
additional noise source associated therewith would include people conversing. A
typical person speaking in a normal voice generates an average noise level of
approximately 57 dBA at a reference distance of 3 feet.57 Conservatively assuming 20
persons were speaking simultaneously in the vicinity of the “outdoor dining area,” a
reference sound level of 70 dBA Leq and 75 dBA Lmax would be generated at the 3-foot
reference distance.
55/ AVC systems include several technologies to improve speech intelligibility while adjusting speaker volume
levels depending on the ambient noise levels, translating into lower noise levels during periods when ambient noise is
low, particularly at night. Normal speaker volume levels are approximately 70 dB(A) at the typical driver-side window
to the speaker post at a distance of about five feet. Activating AVC with a background sound level of approximately 45
dB(A) near the listener should decrease sound speaker sound levels to about 60 dB(A) or less at the same distance.

Based on a separation distance of about 100 feet, assuming no shielding, the predicted
average and maximum noise levels would be 40 dB Leq and 45 dB Lmax, respectively.
Those noise levels conform to the exterior noise standards presented in: (1) Section
22.28.080 (Exterior Noise Standards) (Table 3-9 [Exterior Noise Standards]) of the
DBMC; and (2) Table 7-1 (Community Noise Compatibility Matrix) in the Public Safety
Element of the 2040 General Plan/CAP. Although, on occasion, noise levels might
exceed those projections, the resulting noise impact would be less than significant
under CEQA.
♦ Idling Vehicles. Vehicles queuing in the “drive-thru” aisle would be located at a lesser
separation distance from those sensitive receptors and would be reasonably
anticipated to generate noise from amplified sound emanating from those vehicles’
sound systems, patrons’ voices, vehicles circulating along the “drive-thru” aisle, and
the starting and idling of engines. The DBMC neither regulates “amplified sound”
emanating from those sound systems nor “non-amplified sound” associated with the
human voice or vehicle-related sources.
Section 415 of the California Penal Code defines the crime of “disturbing the peace” as,
among other causes, “maliciously and willfully disturb[ing] another person by loud and
unreasonable noise.” Because enforcement requires the offended party to file legal
action, that code section would have limited application against any intermittent noise
sources or noise generators temporarily operating within the parking lot and/or “drive-
thru” aisle.
Pursuant to the CVC, relative to vehicle noise associated with exhaust systems:
◊ Every motor vehicle subject to registration shall at all times be equipped with an
adequate muffler in constant operation and properly maintained to prevent any
excessive or unusual noise, and no muffler or exhaust system shall be equipped
with a cutout, bypass, or similar device (Section 27150[a], CVC).
◊ No person shall modify the exhaust system of a motor vehicle in a manner which
will amplify or increase the noise emitted by the motor of the vehicle so that the
vehicle is not in compliance with the provisions of Section 27150 or exceeds the
noise limits established for the type of vehicle in Article 2.5 (commencing with
Section 27200). No person shall operate a motor vehicle with an exhaust system
so modified (Section 27151[a], CVC).
◊ For the purposes of exhaust systems installed on motor vehicles with a
manufacturer’s gross vehicle weight rating of less than 6,000 pounds, other than
motorcycles, a sound level of 95 dbA or less, when tested in accordance with
Society of Automotive Engineers Standard J1169 May 1998, complies with this
section. Motor vehicle exhaust systems or parts thereof include, but are not limited
to, nonoriginal exhaust equipment (Section 27151[b], CVC).
Subject to the age of the vehicle, more restrictive federal standards are specified in 40
CFR 205.52 (Vehicle Noise Emission Standards). As specified, in part, therein:
“Vehicles which are manufactured after the following effective dates shall be designed,
built and equipped so that they will not produce sound emissions in excess of the levels
indicated.” Effective on and after January 1, 1988, the allowable sound level is 80 dBA.
The above provisions do not encompass “after-market” actions (e.g., installation of
speakers, woofers, and subwoofers) installed by vehicle owners.

Estimates of noise levels associated with the proposed “fast-food restaurant” (with
“drive-thru”) are based on noise measures conducted for a proposed “Raising Cane’s
Restaurant” (Aliso Viejo) based on the following assumptions: (1) the average noise
level for vehicle noise, treated as moving point sources, generate approximately 44
dBA Leq at 50 feet; (2) menu board speakers generate a noise level of approximately
80 dBA at five feet; (3) patrons at the “outdoor dining area” generate an average noise
level of 85 dBA at five feet; and (4) vehicles, menu board speakers, and patio patrons
generate a simultaneous maximum noise level of approximately 80 dBA at five feet.58
Based on an assumed separation distance of approximately 100 feet between vehicles
accessing the “drive-thru” lane and proximal sensitive receptors, the resulting noise
level would be approximately 62 dBA which is lower than the existing ambient noise
levels at the property boundary of abutting residences.59
Absent any “amplified sound” from car radios and sound systems, idling vehicles
typically produce noise levels of between 52 to 54 dBA Lmax at 30 feet from the source.
Those noise levels would atmospherically attenuate to between 44 and 45 dBA at the
property lines of the nearest residential receptors. Noise associated with idling vehicles
noise would, in whole or in part, be masked by background noise from traffic traveling
along the Pomona (SR-60) Freeway and Brea Canyon Road.
Estimated noise attributable to queuing vehicles would conform to the exterior noise
standards presented in: (1) Section 22.28.080 (Exterior Noise Standards) (Table 3-9
[Exterior Noise Standards]) of the DBMC; and (2) Table 7-1 (Community Noise
Compatibility Matrix) in the Public Safety Element of the 2040 General Plan/CAP.
Although vehicles and motorcycles with modified muffler systems might, on occasion,
create noise levels exceeding those projections, based on compliance with exterior
noise standards, the resulting noise impact would be less than significant under CEQA.
Because the maximum noise generated by the “fast-food restaurant” (with “drive-thru”) would
likely be audible during periods with low ambient traffic noise levels and during occasional
loud activities associated therewith (such as from queuing vehicles playing loud music and
vehicles equipped with loud engines and/or modified muffler systems), the operation of the
“fast-food restaurant” will, at times, create intermittent, audible noises perceptible at adjacent
residences. By placing operating motor vehicles in closer proximity to those receptors, those
conditions might be further exacerbated if the number of vehicles queuing in the “drive-thru”
exceed that lane’s available capacity.
An existing CMB wall, extending approximately 92 feet eastward from Brea Canyon Road
(transitioning into an existing chain-link fence that extends northward and then southeasterly
therefrom), separates a portion of the northwestern boundary of the project site from the
adjoining “Farmer Boys Restaurant” (810 Brea Canyon Road, Diamond Bar). Additionally,
the project site is separated from the existing residential properties located along Lycoming
Street and Dryander Drive by an existing 50-foot-wide County flood control channel (PD 1445)
(Diamond Bar Creek). Neither the chain-link fence nor the flood control channel would

effectively shield those residences from any spillover noise associated with the use of the
proposed “drive-thru” aisle.
As specified, in part, in Section 22.16.080 (Screening and Buffering) of the DBMC: “An
opaque screen consisting of plant material and a masonry wall, six feet in height, shall be
installed along parcel boundaries whenever a commercial development adjoins a
residential zoning district.” Although not specified on the most current architectural plans
(G/A/A Architects, September 8, 2021), the Applicant has notified the Department of its intent
to construct a 6-foot-tall CMB wall along the project site’s northern boundary.
The installation of a minimum 6-foot-tall continuous CMB, or equivalent, wall extending along
the northern property boundary, in combination with proposed landscape improvements,
would screen those sensitive receptors from those operational noise sources associated
with the proposed “retail/restaurant” (“QSR-1”) building and reduce noise impacts to a less-
than-significant level under CEQA.

As defined in Section 8.12.240 (Definitions), Chapter 8.12 (Environmental Protection), Title
8 (Health and Safety) of the DBMC:
Residential property means a parcel of real property which is developed and used
either in part or in whole for residential purposes, other than transient uses such
as hotels and motels. In cases of multiple land uses of any property, the zoning
classification of such property shall be applicable [emphasis added].
As with the 2019 BCBP, there is no existing on-site population and no existing on-site
residential uses on the project site that will be “displaced” or otherwise adversely affected
as a result of the approval, construction, and operation of the 2021 Proposed Revised BCBP.
As proposed, with regards to the “hotel,” the implementation of the 2021 Proposed Revised
BCBP would increase the number of proposed guest rooms from 109 to 124. Since a
“hotel” is not categorized as a residential use, no increase in on-site resident population
will result therefrom.
As defined in Section 3.16.020 (Definitions), Chapter 3.16 (Transient Occupancy Tax), Title
3 (Revenue and Finance) of the DBMC:
Hotel means any structure or any portion of any such structure, which is occupied
or intended or designed for occupancy by transients for dwelling, lodging or
sleeping purposes, and includes any hotel, inn, tourist home or house, motel,
studio hotel, bachelor hotel, lodginghouse, roominghouse, apartment house,
dormitory, public or private club, mobile home or house trailer at a fixed location,
or other similar structure or portion thereof [emphasis added].
As defined in Section 3.16.020 of the DBMC:
Transient means any person who exercises occupancy or is entitled to occupancy
by reason of concession, permit, right of access, license or other agreement for a
period of 30 consecutive calendar days or less, counting portions of calendar
days as full days. Any such person so occupying space in a hotel shall be deemed
to be a transient until the period of 30 days has expired unless there is an
agreement in writing between the operator and the occupant providing for a longer
period of occupancy. In determining whether a person is a transient, uninterrupted
periods of time extending both prior and subsequent to the effective date of
Ordinance No. 14(1989) may be considered.
That 30-day provision is reinforced by the 2019 CBC. Chapter 2 (Definitions) of the 2019
CBC includes “hotels” in its broader definition of “places of lodging”:
A facility operated by a private entity whose operations affect commerce and fall
within at least one of the following categories: (1) Place of lodging, except for an
establishment located within a facility that contains not more than five rooms for
rent or hire and that actually is occupied by the proprietor of the establishment as
the residence of the proprietor. For purposes of this code, a facility is a ‘place of
lodging’ if it is (i) An inn, hotel or motel; or (ii) A facility that (A) Provides guest
rooms for sleeping for stays that primarily are short-term in nature (generally 30
days or less) where the occupant does not have the right to return to a specific
room or unit after the conclusion of his or her stay; and (B) Provides guest rooms
under conditions and with amenities similar to a hotel, motel, or inn, including the
following: (1) On- or off-site management and reservations service; (2) Rooms

available on a walk-up or call-in basis; (3) Availability of housekeeping or linen
service; and (4) Acceptance of reservations for a guest room type without
guaranteeing a particular unit or room until check-in, and without a prior lease or
security deposit [emphasis added].
As so defined, the 2021 Proposed Revised BCBP includes no residential component and
does not call for the extension of any infrastructure or roads that would indirectly induce
unplanned population growth in the area.
Within the City, similar to the 2019 Approved BCBP, the 2021 Proposed Revised BCBP will
create an unspecified number of new: (1) long-term, permanent full-time; and (2) short-term,
part-time jobs. Although unspecified, the likely number of permanent, long-term jobs
attributable to the 2021 Proposed Revised BCBP is not projected to induce an indirect
demand for new housing either within the City or elsewhere throughout the San Gabriel
Valley.
As proposed, the 6,500 GSF single or multitenant “retail/restaurant” (“QSR-1”) building will
replace the 8,900 GSF GSF multitenant “medical office” building (“Parcel 2”) associated with
the 2019 Approved BCBP. Empirically, wage levels for restaurant workers might, on
average, be less than those associated with “medical office” workers. Similarly, based on
the reduced building square footage, the number of equivalent full-time workers associated
with the “retail/restaurant” use would reasonably be expected to be less than those
associated with the “medical office” use.
Income from part-time jobs is typically not sufficient to purchase residential property in the
southern California area but can contribute, either in whole or in part, to the payment of costs
associated with rental housing, typically multi-family apartments. Because there is currently
a large inventory of multi-family housing within the San Gabriel Valley area, the 2021
Proposed Revised BCBP is not anticipated to substantially contribute to the need for new
multi-family housing in the general project area. Based on the anticipated reduction in on-
site employment, the resulting indirect housing-related impacts attributable to the 2021
Proposed Revised BCBP would be expected to be less than those attributable to the 2019
Approved BCBP.

Preliminary Determination: Less-than-Significant Impact
Findings of Fact: Relative to public services, no project-level mitigation measures were
identified in the 2019 Approved BCBP/MND or adopted by the Council in Resolution No.
2019-40 (November 19, 2019). Additionally, none of the program-level mitigation measures
included in the 2040 General Plan/CAP/FPEIR/MND and adopted by the Council (Resolution
No. 2019-43, December 17, 2019), appear directly relevant to the 2021 Proposed Revised
BCBP.
The project site is located within one-quarter mile of an existing school (Discovery World
Preschool and Private Elementary School, 801 Brea Canyon Road, Diamond Bar). Other more
distal schools in the general project area include Walnut Elementary School (841 Glenwick
Avenue, Walnut) and Ron Hockwalt Academies (High School) (476 Lemon Avenue,
Industry).
As indicated in Table A-1 (Comparative Development Analysis – 2019 Approved BCBP and
2021 Proposed Revised BCBP [September 8, 2021]), although a change in authorized land
use is being proposed, the total square footage of all on-site development would increase
by only 385 GSF. The potential impacts of that increase on proximal school facilities would
be de minimis. Absent a residential component, the 2021 Proposed Revised BCBP would
not predicate the need for new or expanded school facilities that could potentially cause or
contribute to significant environmental effects.
No neighborhood, local, community, or regional parks are located within one mile of the
project site. The 2021 Proposed Revised BCBP is neither projected to contribute, either
directly or indirectly, to potential impacts thereupon nor predicate the need for new park
facilities that could potentially cause or contribute to significant environmental effects.
The 2021 Proposed Revised BCBP is not expected to result in any substantial adverse
physical impacts associated with the provision of any new or physically altered library or
other governmental facilities, the construction of which could potentially cause or contribute
to significant environmental impacts.
Response times and service ratios for both the Los Angeles County Sheriff’s Department
(LACSD) and Los Angeles County Fire Department (LACoFD) would not change from those
levels associated with the 2019 Approved BCBP. Fire protection and law enforcement are
separately addressed herein.
♦ Fire Protection. Fire protection services, including structural fire protection,
emergency medical and rescue services, hazardous inspections and response, and
public education activities, in the City are provided by the Los Angeles County
Consolidated Fire Protection District (more commonly referred to as LACoFD). The

LACoFD presently maintains three fire stations within a two-mile radius of the project
site (Stations 61, 119, and 120). As documented in the 2019 Approved BCBP/MND,
emergency fire response capabilities from those facilities conform to and exceeds
County standards.
The proposed changes to the 2019 Approved BCBP predicated by the approval,
construction, and operation of the 2021 Proposed Revised BCBP do not raise any
additional environmental issues relating, either directly or indirectly, to “fire protection”
that were not adequately addressed in the 2019 Approved BCBP/MND.
♦ Law Enforcement. The proposed changes to the 2019 Approved BCBP predicated
by the approval, construction, and operation of the 2021 Proposed Revised BCBP do
not, therefore, raise any additional environmental issues relating, either directly or
indirectly, to “law enforcement.”

Preliminary Determination: Less-than-Significant Impact
Findings of Fact: Relative to recreation, no project-level mitigation measures were identified

The 2021 Proposed Revised BCBP neither includes any “public recreational facilities” nor
does the 2040 General Plan or DBMC explicitly require the provision thereof.
As indicated, in part, in Section 22.16.070(1) of the DBMC: “Multitenant commercial centers
one acre in size and larger shall provide a minimum of 0.01 percent of the total land area of
the center as useable pedestrian-oriented open space, including plazas, patios, courtyards,
and outdoor seating areas.” Although intended to be restricted to authorized site users, that
“useable pedestrian-oriented open space” could be interpreted as constituting “other” and/or
“private” recreational facilities. Because the project acreage remains unchanged, the 2021

No neighborhood, local, community, or regional parks are located within one mile of the

Preliminary Determination: Less-than-Significant Impact
Findings of Fact: The 2019 Approved BCBP/MND concluded that the 2019 Approved
BCBP’s transportation-related impacts would be “less-than-significant” and no
accompanying transportation-related project-level mitigation measures were, therefore,
included in in the 2019 Approved BCBP/MND, 2019 Approved BCBP/MND/MRMP, and/or
Resolution No. 2019-40 (November 19, 2019). On November 19, 2019, when the 2019
Approved BCBP was approved by the Council, no analytical requirements then existed and
no thresholds of significance criteria for VMT had been formulated by the City. Threshold of
significance criteria for VMT were subsequently identified in the “City of Diamond Bar
Transportation Study Guidelines for Vehicle Miles Traveled and Level of Service
Assessment” (September 2020) (2020 Transportation Study Guidelines).

The State-mandated requirement to include a VMT analysis as part of the CEQA process
did not become effective until July 1, 2020. As outlined in the City’s 2020 Transportation
Study Guidelines, an additional transportation-related analysis and a new set of thresholds
of significance criterion addressing VMT impacts were subsequently formulated. Because
its approval (November 19, 2019) predated the publication of those 2020 Transportation
Study Guidelines, neither those analytical requirements nor any threshold of significance
criteria relating to potential VMT impacts were included in the 2019 Approved BCBP/MND.
With regards to both the 2019 Approved BCBP and 2021 Proposed Revised BCBP, pursuant
to the City’s 2020 Transportation Study Guidelines, as indicated in “Brea Canyon Business
Center, Diamond Bar – Vehicle Miles Traveled (VMT) Analysis” (Linscott Law & Greenspan,
September 16, 2021) (2021 Proposed Revised BCBP/VMT), potentially significant VMT-
related impacts were identified therein.
Although initially formulated in the 2019 Approved BCBP/MND in response to potentially
significant operational air quality impacts, the following “revised” mitigation measure remains
applicable to operational air quality impacts but has also been repurposed to reduce
transportation-related (i.e., vehicle miles traveled and peak-period parking demands)
impacts. The proposed revisions thereto included the addition of a third stated goal
(reduction in peak-period parking demands), including associated performance standards.
Revised MM-3. Transportation Demand Management. Prior to the issuance of
final subdivision map, in compliance with the provisions of Chapter 22.40
(Transportation Demand Management) of the “City of Diamond Bar Municipal
Code,” the Applicant shall submit and the Community Development Director shall
approve a detailed “transportation demand management” (TDM) program
encompassing the proposed project and each of the uses contemplated therein,
including the weekday and weekend peak-period parking demands associated
therewith. The TDM program shall include separate operational components
addressing strategies, singularly or in combination, to reduce: (1) the number of
average daily vehicle trips (ADT) attributable to the proposed project; (2) and the
total number of vehicle miles traveled (VMT) associated therewith; and (3) peak-
period parking demands.
The TDM shall include reasonable and feasible actions and endeavors sufficient to
achieve: (1) a twenty (20) percent reduction in ADT and VMT over conditions which
would otherwise occur absent the TDM; or (2) a fifteen (15) percent reduction in
weekday and weekend peak-period parking demands that would occur absent the
TDM; or (3) a 15 percent project-specific VMT-related reduction below the City’s
projected per service population (VMT/SP) level that would occur absent the TDM.
The proposed project’s “business-owners” association/condominium association”
(BOA) or similar representative management entity comprised of all owners of
interest thereupon shall: (1) not less than annually, implement reasonable outreach
efforts to all owners, occupants, and tenants for the purpose of providing
information and updates concern the TDM program and its effectuation; (2)
implement an active and on-going TDM monitoring program for the purpose of
assessing progress toward the achievement of the stated performance standards;
and (3) periodically revise and/or modify the TDM program and undertake such
further actions as may be reasonable and appropriate to demonstrate the
achievement of those standards. The BOA or management entity shall make those
records available to the Community Development Director upon request.

Applicant-proposed changes to the 2019 Approved BCBP include, but are not limited to,
physical changes to both the design and operation of the project’s driveway and central
median along Brea Canyon Road; changes to internal and external circulation patterns and
turning movements; the introduction of new land uses not previously contemplate on the
project site; and a corresponding change in associated on-site parking demands. The
proposed changes in on-site uses, including the incorporation of a “restaurant with outdoor

operational changes to both on-site circulation and off-site transportation impacts.
As part of the 2021 Development Application, the Applicant submitted and the Department
subsequently reviewed and accepted for analytical purposes, a number of traffic-related
technical studies, including, but not limited to: (1) “Revised Traffic Impact Analysis Report

♦ 2021 Proposed Revised BCBP/TIA. Senate Bill (SB) 743, as codified at Section
21099, et seq. of the PRC, passed in 2013 and mandated a transition away from level
of service (LOS) as a way of measuring the significance of traffic impacts under CEQA.
Section 21099(b)(2) provides that:
Upon certification of the guidelines by the Secretary of the Natural Resources
Agency pursuant to this section, automobile delay, as described solely by
level of service or similar measures of vehicular capacity or traffic congestion,
shall not be considered a significant impact on the environment pursuant to
this division, except in locations specifically identified in the guidelines, if any.
In lieu of LOS, SB 743 requires agencies to transition to “vehicle miles traveled.”
Except as noted, although LOS analysis is no longer addressed under CEQA, a typical
LOS assessment commences with the formulation of the estimated number of ADT
associated with a proposed project. Estimated ADTs continue to play a relevant role in
determining potential operational air quality impacts (Section 21099[b][3], CEQA). Trip
generation estimates associated with the 2019 Proposed Revised BCBP are, therefore,
provided herein.
As indicated in the 2021 Proposed Revised BCBP/TIA, on a “typical” weekday, the 2019
Approved BCBP would generate 2,077 daily trips (50% inbound, 50% outbound),
including 156 (115 inbound, 41 outbound) AM and 187 (63 inbound, 124 outbound) PM
peak hour trips. With regards to the 2021 Proposed Revised BCBP, on a “typical”
weekday, the traffic impact analysis assumes a total of 4,321 ADT, of which 586 ADT

(13.6 percent) are assumed to constitute either “internal capture reduction” or “pass-by
trips,” resulting in a total of 3,735 ADT (50% inbound, 50% outbound), including 216
(152 inbound, 64 outbound) AM peak hour and 287 (111 inbound, 176 outbound) PM
peak hour trips.
When comparing the 2019 Approved BCBP and 2021 Proposed Revised BCBP, the
2021 Proposed Revised BCBP would generate an additional 1,652 daily weekday trips
(416 inbound, 416 outbound), including 60 additional AM peak hour (37 inbound, 23
outbound) and 100 additional PM peak hour (48 inbound, 52 outbound) trips.
♦ 2021 Proposed Revised BCBP/VMT. As indicated in the 2021 Proposed Revised
BCBP/VMT, in order to assess potential VMT-related impacts, a post-approval VMT
analysis was conducted assessing the 2019 Approved BCBP. As indicated therein, “a
full VMT analysis utilizing the Southern California Association of Governments
Regional Travel Demand Model (SCAG RTDM) has been used to determine the VMT
per service population (VMT/SP) for the [2019] Approved [BCBP] Project and the
[2021] Proposed [Revised BCBP] Project consistent with the City’s guideline to
determine the significance of the potential VMT impact.”60 With regards to both the
2019 Approved BCBP and 2021 Proposed Revised BCBP, the resulting analysis
concluded:
[T]he [2019] Approved [BCBP] Project Generated VMT per service population
[38.98 VMT/SP] exceeds the City of Diamond Bar baseline VMT per service
population [34.14 VMT/SP] and based on the thresholds and criteria outlined
in this report, the [2019] Approved [BCBP] Project will have a significant, but
mitigatable VMT impact.
[T]he [2021] Proposed [Revised BCBP] Project Generated VMT per service
population [39.20 VMT/SP] exceeds the City of Diamond Bar baseline VMT
per service population [34.14 VMT/SP]. Based on the thresholds and criteria
outlined in this report, the [2021] Proposed [Revised BCBP] Project will have
a significant, but mitigatable VMT impact.61
The 2021 Proposed Revised BCBP/VMT concluded:
If the [2019] Approved [BCBP] Project’s transportation impacts were
evaluated under the current CEQA guidelines using the City’s current VMT
guidelines, mitigation measures would be required to offset the [2019]
Approved [BCBP] Project’s significant VMT impact. The mitigation measures
would include implementation of the Transportation Demand Management
(TDM) strategies to decrease the VMT per service population to less than 15%
below the City baseline VMT per service population and thus reduce the [2019
Approved BCBP] Project (Approved) VMT impact to less than significant.
Given the [2021] Proposed [Revised BCBP] Project Generated VMT per
service population exceeds the City of Diamond Bar baseline VMT per service
population in the amount similar to that of the [2019] Approved [BCBP] Project
and hence has a similar impact to that of [2019] Approved [BCBP] Project, the

VMT mitigation measures would in all likelihood be similar/identical to that
which would be recommended for the [2019] Approved [BCBP] Project.
The mitigation measures would include implementation of the Transportation
Demand Management (TDM) strategies to decrease the VMT per service
population to less than 15% below the City baseline VMT per service
population and thus reduce the [2019 Approved BCBP and the 2021 Proposed
Revised BCBP] Project (Approved) VMT impact to less than significant.62
Environmental issues relating to VMT, vehicle queuing, and alternative modes of
transportation are separately addressed below.
Vehicle Miles Traveled Analysis
No VMT analysis was conducted in response to the 2019 Approved BCBP or included in
the 2019 Approved BCBP/MND. Additionally, no threshold of significance criteria had
been formulated by the Lead Agency at the time of adoption of the 2019 Approved BCBP
or approval of the 2019 Approved BCBP/MND.
Since adoption of the 2019 Approved BCBP/MND, State-mandated changes have
occurred in the manner in which defensible CEQA-based traffic analyses are to be
performed. Specifically, CEQA now mandates that certain non-exempt projects quantify
the total VMT associated with those projects.63
The 2040 General Plan/CAP includes specific textual and policy declarations relating
to VMT. As indicated in the Circulation Element of the 2040 General Plan/CAP:
VMT is the State preferred performance metric for environmental analyses
pursuant to CEQA to describe the overall amount of travel in the City based
on distance and is directly related to fuel consumption, air pollution, and GHG
emissions. VMT is defined as the total mileage traveled by all vehicles.
Although VMT relates specifically to automobiles, it is able to capture the
effects of development patterns such as land use mix and density along with
transit, bike, and pedestrian infrastructure improvements by reflecting their
impacts on vehicle trip generation and trip lengths.64
62/ Ibid., p 8.
63/ The Governor’s Office of Planning and Research (OPR) recommends that: (1) projects that generate less
than 110 trips/day may be considered to have a less-than-significant VMT impacts (this threshold is not based on VMT
but rather on the CEQA categorical exemption for existing facilities, including additions to existing structures of up to
10,000 square feet); (2) for those projects located in “transit priority areas,” lead agencies generally should presume
that certain projects (including residential, retail, office projects, and projects that are a mix of these uses) proposed
within one-half mile of an existing “major transit stop” or an existing stop along a “high-quality transit corridor” (HQTA)
will have a less-than-significant impact on VMT; (3) local-serving retail projects may be considered to have less than
significant VMT impacts; (4) redevelopment projects that result in a net reduction in VMT may be considered to have
less-than-significant VMT impacts; and (5) projects that include 100 percent affordable housing in infill locations can be
presumed to have a less-than-significant VMT impact.
A “transit priority area” is defined as “an area within one-half mile of a major transit stop that is existing or planned,
if the planned stop is scheduled to be completed within the planning horizon included in a Transportation Improvement
Program.” A “major transit stop” means “a site containing an existing rail transit station, a ferry terminal served by either
a bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service of 15 minutes
or less during the morning and afternoon peak commute periods.” A HQTA is a corridor with fixed route bus service
with service intervals no longer than 15 minutes during peak commute hours.

Corresponding 2040 General Plan/CAP policies include:
◊ Balance meeting LOS standards with the need to reduce VMT through
maintaining and supporting multi-modal connectivity such as transit, bicycling,
walking, and by encouraging infill development with a pedestrian-friendly
urban design character (Policy CR-P-12).
◊ Incorporate criteria in the Development Code to allow reductions in parking
requirements in exchange for VMT reduction measures (Policy CR-P-54).
In September 2020, the City published the “City of Diamond Bar Transportation Study
Guidelines for Vehicle Miles Traveled and Level of Service Assessment” (2020
Transportation Study Guidelines). Because the 2020 Transportation Study Guidelines
was prepared subsequent to the approval of the 2019 Approved BCBP (November 19,
2019), the traffic and transportation analysis presented in the 2019 Approved
BCBP/MND would neither be expected nor obligated to be fully compliant therewith.
Relative to VMT analysis, as indicated in the 2020 Transportation Study Guidelines:
For purposes of SB 743 compliance, a VMT analysis should be conducted for
land use projects as deemed necessary by the City Traffic Engineer and would
apply to projects that have the potential to increase the baseline VMT per
service population (e.g., population plus employment) for the City. Normalizing
VMT per service population (e.g., creating a rate by dividing VMT by service
population) provides a transportation efficiency metric that the analysis is
based on. All assumptions and methodologies of the VMT analysis are subject
to review and approval by the City Traffic Engineer.65
In order to assess the significance of project-related VMT impacts, the following
threshold of significance criteria was formulated therein:
VMT thresholds provided below are to be applied to determine potential
project generated VMT impacts and project’s effect on VMT impacts. A project
would result in a significant project generated VMT impact if either of the
following conditions are satisfied: (1) The baseline project generated VMT per
service population exceeds the 15% below the City of Diamond Bar baseline
VMT per service population, or (2) The cumulative project generated VMT per
service population [VMT/SP] exceeds 15% below the City of Diamond Bar
baseline VMT per service population The project’s effect on VMT would be
considered significant if it resulted in the following condition being satisfied:
(1) The cumulative link-level boundary Citywide VMT per service population
increases under the plus project condition compared to the no project
condition. . .[T]he cumulative no project shall reflect the adopted [SCAG 2016]
RTP/SCS; as such, if a project is consistent with the SCAG [2016] RTP/SCS,
then the cumulative impacts (project effect on VMT) shall be considered less
than significant subject to consideration of other substantial evidence.66

The following mitigation strategies are available to reduce VMT impacts: (1)
Modify the project’s-built environment characteristics to reduce VMT
generated by the project. (2) Implement Transportation Demand Management
(TDM) measures to reduce VMT generated by the project. (3) Participate in a
VMT fee program and/or VMT mitigation exchange/banking program (if
available) to reduce VMT from the project or other land uses to achieve
acceptable levels. . .VMT reductions should be evaluated as part of the VMT
impact analysis using state-of-the-practice methodologies recognizing that
many of the TDM strategies are dependent on building tenant performance
over time. As such, actual VMT reduction cannot be reliably predicted and
monitoring may be necessary to gauge performance related to mitigation
expectations. When a project is found to have a significant impact under
CEQA, the City requires developers and the business community to assist in
reducing peak hour and total vehicular trips by implementing Transportation
Demand Management Plans (TDMs).67
In accordance with the 2020 Transportation Study Guidelines, in order to assess both
VMT-related and other traffic impacts associated with the 2021 Proposed Revised
BCBP, updated project-specific traffic analyses, including VMTs, were submitted by the
Applicant and independently reviewed by the Departments. As indicated in the 2019
Proposed Revised BCBP/VMT, as “approved” by the City of Diamond Bar Public Works
Department on September 23, 2021, in order to assess potential VMT-related impacts
attributable to the 2021 Proposed Revised BCBP, a post-approval VMT analysis was
conducted for the purpose of comparing the 2021 Proposed Revised BCBP to the
corresponding impacts attributable to the 2019 Approved BCBP.
As indicated therein, “a full VMT analysis utilizing the Southern California Association
of Governments Regional Travel Demand Model (SCAG RTDM) has been used to
determine the VMT per service population (VMT/SP) for the [2019] Approved [BCBP]
Project and the [2021] Proposed [Revised BCBP] Project consistent with the City’s
guideline to determine the significance of the potential VMT impact.”68 With regards to
both the 2019 Approved BCBP and 2021 Proposed Revised BCBP, the resulting
analysis concluded that the 2021 Proposed Revised BCBP’s projected 39.20 VMT/SP
exceeds the City’s baseline of 34.14 VMT/SP by 14.82 percent (39.20/34.14 =
1.1482).69
Based on the identification of those “significant but mitigable VMT impacts, the
“approved” traffic study concluded:
If the [2019] Approved [BCBP] Project’s transportation impacts were
evaluated under the current CEQA guidelines using the City’s current VMT
guidelines, mitigation measures would be required to offset the [2019]
Approved [BCBP] Project’s significant VMT impact. The mitigation measures
would include implementation of the Transportation Demand Management
(TDM) strategies to decrease the VMT per service population to less than 15%
below the City baseline VMT per service population and thus reduce the [2019
Approved BCBP] Project (Approved) VMT impact to less than significant.

Given the [2021] Proposed [Revised BCBP] Project Generated VMT per
service population exceeds the City of Diamond Bar baseline VMT per service
population in the amount similar to that of the [2019] Approved [BCBP] Project
and hence has a similar impact to that of [2019] Approved [BCBP] Project, the
VMT mitigation measures would in all likelihood be similar/identical to that
which would be recommended for the [2019] Approved [BCBP] Project.
The mitigation measures would include implementation of the Transportation
Demand Management (TDM) strategies to decrease the VMT per service
population to less than 15% below the City baseline VMT per service
population and thus reduce the [2019 Approved BCBP and the 2021 Proposed
Revised BCBP] Project (Approved) VMT impact to less than significant.70
Unless otherwise waived, all projects within the City are subject to compliance with
applicable DBMC provisions. As specified in the 2019 Approved BCBP/MND:
As required under Section 22.40.030 (Transportation Demand Management
Program Requirements) in Chapter 22.40 (Transportation Demand
Management) of the MC: “All applicable projects shall prepare and implement
a transportation demand management (TDM) program which will encourage
increased ridesharing and the use of alternative transportation modes.” In
accordance therein, based on the proposed project’s 118,471 square feet of
development, among other obligations, [a TDM program shall include]
carpool/vanpool preferential parking, a bicycle parking/storage area, a
carpool/vanpool loading area, a transit waiting shelter, and joint access and
shared parking.
Because the ordinance does not specify the timing for submitting the TDM
program, the Department has discretion as to: (1) when that program should
be submitted; and (2) beyond the minimum requirements specified in the MC,
the level of specificity relating thereto. Since the requisite information could
have implications relative to the configuration of the proposed site plan, at a
minimum, the Department has both stipulated the timing for TDM program
submittal and formulated specific performance standards relative to targeted
reductions in both average daily vehicle trips (ADT) and vehicle miles traveled
(VMT). As a recommended mitigation measure, more detailed information
beyond that incorporated on the proposed site plan shall be required prior to
final subdivision map approval.71
As included in Table A-2 (2021 Proposed Revised BCBP – Adopted/Revised/Proposed
Mitigation Measures) and as referenced herein, “Revised MM-3” (Transportation
Demand Management) stipulated, in part, that the “TDM shall include reasonable and
feasible actions and endeavors sufficient to achieve: (1) a twenty (20) percent reduction
in ADT over conditions which would otherwise occur absent the TDM; or (2) a fifteen
(15) percent reduction in weekday and weekend peak-period parking demands that
would occur absent the TDM; or (3) a 15 percent project-specific VMT-related reduction
below the City’s projected per service population (VMT/SP) level that would occur
absent the TDM.” The “revised” project-level mitigation measures will reduce potentially
significant VMT impacts to a less-than-significant level under CEQA.

Queuing Capacity Analysis
One of the major issues in the analysis of any traffic system is the analysis of delay.
Delay may be defined as the difference between the actual travel time on a given
segment and some ideal travel time of that segment. In queuing theory, delay means
when demand exceeds capacity. Queuing delay typically includes the following three
input parameters: (1) mean arrival rate; (2) mean service rate; and (3) the number of
servers.
Mean arrival rate (λ) is the rate at which customers arrive at a service facility and
typically expressed in either flow (customers/hour or vehicles/hour) or in time headway
(seconds/customer or seconds/vehicle). If inter arrival time that is time headway (h) is
known, the arrival rate can be found out from the equation: λ = 3,600/h.
Mean service rate (µ) is the rate at which customers or vehicles depart from a service
facility and is typically expressed in either flow (customers/hour or vehicles/hour) or
time headway (seconds/customer or seconds/vehicle). Both the number of servers and
the manner in which they work (parallel servers or series servers) are also variable. If
time headway (h) is known, the service rate can be determined by the equation: µ =
3,600/h.
Queue discipline is a parameter that explains how the customers arrive at a service
facility. The various types of queue disciplines include: (1) “served in random order”
(SIRO); (2) “first-in-first-out” (FIFO); (3) “first-in-last-out” (FILO); and (4) “priority
scheduling.” The queue discipline if “fast-food restaurants” (with “drive-thru”) is
generally FIFO; however, “priority scheduling” would also exist when “mobile order
pickup” and “curbside delivery services” are also provided.
With regards to the 2021 Proposed Revised BCBP, inclusive of the unaltered
components of the 2019 Approved BCBP, the following four separate queuing analyses
are addressed herein.
◊ “Turn-Pocket Queuing Analysis. Based on the relatively short distance between
the project’s driveway and the northbound left-turn pocket at the Brea Canyon
Road/Lycoming Street intersection, a “turn pocket” queuing evaluation was
included in the 2021 Proposed Revised BCBP/TIA. As indicate in Table A-8 (Brea
Canyon Road/Lycoming Street Intersection and Project Driveway Queuing
Analyses), based on the analysis presented therein, the proposed queues for the
northbound left-turn at the Brea Canyon Road/Lycoming Street intersection are
forecast to be adequate under both “opening year cumulative plus project” and
“Year 2040 cumulative plus project” traffic conditions.
Project-related improvements to Intersection No. 5 (Brea Canyon Road at
Lycoming Street) include: (1) the restriping of the northbound approach to provide
an additional exclusive northbound left-turn lane; (2) the restriping of the
eastbound shared left/through/right-turn lane into an exclusive left-turn lane and
shared through/right-turn lane; (3) the restriping of the westbound departure to
accommodate two receiving lanes; and (4) associated changes to the existing
traffic signal.

◊ Left-Turn Lane Queuing Analysis. As proposed, left-turn movement from the
project’s driveway to southbound Brea Canyon Road would be prohibited. As
proposed, vehicles traveling southbound on Brea Canyon Road would be able to
turn left onto the site.
◊ Project Driveway Queuing Analysis. As indicated in the 2021 Proposed Revised
BCBP/TIA, although the projected queue exceeds the storage length from the back
of the sidewalk to the end-of-curb return of the first internal on-site intersection, as
needed, the project site has the ability to accommodate additional spillover queue.
As indicated in Table A-9 (2021 Proposed Revised BCBP - Brea Canyon
Road/Lycoming Street Intersection and Project Driveway Queuing Analyses),
westbound right-turn at the project driveway along Brea Canyon Road is forecast
to be adequate under both “opening year cumulative-plus-project” and “Year 2040
cumulative-plus-project” conditions.

As illustrated in Figure A-1 (2021 Proposed Revised BCBP - Queuing Analysis at
Project Driveway),72 the projected 95th percentile queue length for exiting
(westbound) vehicles exceeds the 105-foot distance provided between the
sidewalk and the end-of-curb return for the first internal on-site intersection during
the “open year cumulative-plus-project” PM peak hour (116 feet) and both “Year

Although neither the length of each queuing vehicle nor separation distance
between vehicles is specified, based on the referenced graphic, a combined
distance of about 22-foot per vehicle has been assumed. The introduction of
medium to large-sized trucks or an increase in separation distances could
potentially impede turning movements from the main driveway to the first internal
on-site intersection.
Should queuing vehicles encroach into the first internal on-site intersection, unless
turning movements were maintained, those vehicles could potentially impede
entering vehicles seeking direct access to the “retail/restaurant” (“QSR-1”)
building (“Parcel 2”), potentially creating a back-up to entering traffic. In response,
the 2021 Proposed Revised BCBP/TIA recommends the posting of signage and
the stripping of that intersection with the notation “KEEP CLEAR” commensurate
with the project’s opening date.
Because additional queuing length is available to the east of the first internal on-
site intersection, sufficient queuing capacity exists on the project site.
◊ “Drive-Thru” Lane Queuing Analysis. The 2021 Proposed Revised BCBP
includes the proposed elimination, redesign, and/or reconfiguration of the
previously approved 8,900 GSF multitenant “medical office” building (“Parcel 2”)
and the introduction of a 6,500 GSF multitenant “retail/restaurant” building (“QSR-
1”), including the introduction of a “fast-food restaurant” (with “drive-thru”), one or
more additional unspecified “restaurants” (without “drive-thru”), and one or more

additional unspecified “retail” uses, and extended operational hours associated
therewith and relating thereto. While some percentage of patrons will elect to enter
the proposed “fast-food restaurant” to order food and/or to order and eat (either
inside or at the “outdoor dining area”), one of the perceived benefits of an
operational “drive-thru” lane is the ability of patrons to remain in their vehicles,
order food, and depart without the need to enter the building.
It has been noted that “drive-thru” traffic varies by restaurant type:
[T]here are noticeable differences in the percentage of customers who
use the drive-thru window for different types of restaurants. A customer
at a hamburger fast food restaurant, such as Burger King or
McDonald's, is more likely to use the drive-thru window than a customer
at a quick-service Mexican restaurant, such as Del Taco or Taco Bell,
or a chicken fast food restaurant, such as Kentucky Fried Chicken or
Popeyes. About 57 percent of customers at hamburger fast food
restaurants use the drive-thru window, compared to 40 percent at
quick-service Mexican restaurants and 38 percent at chicken fast food
restaurants. . . McDonald's, the largest fast-food chain, generates 65
percent of its sales in the United States from drive-thru customers.73
The following key points were identified in “Drive-Thru Ordering Surged during the
Pandemic. Fast-Food Chains Don’t Think it’s a Fad” (March 12, 2021):
o Drive-thru ordering surged over the last year as the coronavirus pandemic
shuttered indoor dining and made consumers wary of entering restaurants;
o Industry experts believe that “drive-thru” ordering will stay above pre-
pandemic levels, even after everyone is vaccinated; and
o Fast-food chains are ramping up investments to make their “drive-thru” lanes
more efficient, while more fast-casual restaurants are adding their first “drive-
thru” lanes.74
As further indicated therein:
After decades as a fast-food staple, drive-thru lanes became the
superstar, helping fast-food chains’ sales rebound faster than those of its
full-service brethren. By December, drive-thru lanes accounted for 44%
of off-premise orders across the entire restaurant industry, according to
the NPD Group. As vaccine distribution ramps up across the United
States, the popularity of drive-thru ordering appears to have staying
power, although industry experts predict that it will moderate some.75

Restaurant preferences and demands may not be geographically universal.
Although not necessarily indicative of the 2021 Proposed Revised BCBP, relative
to the determination of an appropriate queuing capacity, a number of potentially
comparative studies were examined by the Department. Those studies included
those associated with three popular southern California restaurants, including
proposed “In-N-Out Restaurant,” “Chick-fil-A Restaurant,” and “Raising Cane’s
Restaurant,” and are cited below.
o In-N-Out Restaurant. For a proposed 3,885 GSF “In-N-Out Restaurant” (42-

82043 State Highway 111, Indio; and (3) Site 3: 78611 State Highway 111,
La Quinta. As indicated, in part, therein:
Our evaluation of this data indicates that on average during the
weekday (Thursday) peak periods, an average queue of 12
vehicles in the drive-through lane can be expected, with an 85th
percentile queue of approximately 17 vehicles, a 95th percentile
queue of approximately 19 vehicles and a max queue of
approximately 23 vehicles. Similarly, our evaluation of this data
also indicates that on average during the weekend (Saturday)
peak periods, an average queue of 12 vehicles in the drive-
through lane can be expected, with an 85th percentile queue of
approximately 16 vehicles, a 95th percentile queue of
approximately 19 vehicles and a max queue of approximately 24
vehicles. The 85th percentile queue represents the number of
vehicles that can be expected in the drive-through lane during the
peak period, and indicates that 85 percent of the drive-through
customers will wait in a line no longer than 17 vehicles; 15 percent
of the customers will wait in a queue of 18 cars or more. Whereas
the 95th percentile queue indicates that 95 percent of the drive-
through customers will wait in a line no longer than 19 vehicles; 5
percent of the customers will wait in a queue of 20 cars or more.
Please note that the 85th percentile “criteria” is the design standard
typically used in the traffic engineering profession.78
Based on the number of queuing vehicles observed, the weekday 85th
percentile was determined to be: (1) Site 1 - 18 vehicles; (2) Site 2 -11
vehicles; and (3) Site 3 - 19 vehicles. Similarly, the weekend 85th percentile
was determined to be: (1) Site 1 - 15 vehicles; (2) Site 2 - 16 vehicles; and
(3) Site 3 - 15 vehicles.79
The above referenced traffic study concluded that a 3,885 GSF “fast-food
restaurant” (with “drive-thru”) translated into the demand for a 17-vehicle
queuing capacity, representing a ratio of 4.38 vehicles per 1,000 GSF.

The TJW Engineering (TJW) analysis was based on pre-COVID-19
observations performed by TJW at the following four Chick-fil-A locations
between January 18 and November 20, 2017 (including a Monday,
Wednesday, Friday, and Saturday dates): (1) 1949 N. Campus Drive,
Upland; (2) 3555 Grand Oaks, Corona; (3) 24011 El Toro Road, Laguna
Hills; and (4) 12190 Foothill Boulevard, Rancho Cucamonga. The square
footages of the four existing restaurants was not, however, explicitly noted.
The TJW analysis concluded: “A typical rule of thumb when designing drive-
through queue storage is that the 85th percentile queue should be chosen
and that the drive-through should be designed to accommodate these
queues. Based on this rule of thumb, the observed 85th percentile queue
length at the four comparable Chick-fil-As is 15 vehicles.”
Pre-COVID-19 queuing observations were performed by Linscott Law &
Greenspan at the following four “Chick-fil-A Restaurants” between August
and September 2019 (Rancho Capistrano) and September 2019
(Pasadena): (1) 12190 Foothill Boulevard, Rancho Cucamonga; (2) 1949 N.
Campus Avenue, Upland; (3) 1700 E. Colorado Boulevard, Pasadena; and
(4) 24180 Magic Mountain Parkway, Santa Clarita.
As presented in Table A-11 (Summary of “Drive-Thru Restaurant” - Service

extracted from Linscott Law & Greenspan’s (LLG) March 2021 analysis,
queuing demands at four Chick-fil-A restaurants (with “drive-thru”) in the

provides a broader sample on which to base the maximum forecast
vehicle queue” for that proposed project.81
As further noted by LLG:
[S]imilar to other existing Chick-fil-A restaurants, it is expected that
Chick-fil-A employees/order takers will be deployed during peak
hours, if necessary, to conduct remote ordering with tablets in order
to expedite drive-through operations. It is recommended that clear
signage directing vehicles to the drive-through service lane be
installed on the project site to minimize unnecessary circulation
within the site. Should the vehicle queue exceed the available
storage space, it is recommended that the project applicant
implement a policy similar to that of other restaurants in which a
staff member will be present to direct the additional vehicle(s) to a
parking or waiting area to ensure that potential queues do not
interfere with on-site circulation or spill back onto adjacent public
right-of-way.82
o Raising Cane’s Restaurant. For a proposed 4,047 GSF “Raising Cane’s
Restaurant” (255 Imperial Highway, Brea) the following information is
extracted from the “Focused Transportation Assessment for the Proposed
Raising Cane’s Project in the City of Brea” (Kimley-Horn and Associates,
December 2020),83 accompanying a categorical exemption.
In order to quantify appropriate queuing capacity, in November 2017, August
2018, and March 2019 (Wednesday, Thursday, and Saturday), pre-COVID-
19 field surveys were conducted at the following three existing “Raising
Cane’s Restaurants” with “drive-thru” lanes: (1) 23971 El Toro Road (Laguna
Hills); (2) 2249 North Tustin Street (Orange); and (3) 11066 Magnolia
Avenue (Riverside).
As configured, the “drive-thru” would provide two side-by-side entry lanes
and two menu boards, allowing the restaurant to take orders from two
customers at the same time. After the menu boards, the two lanes would
merge into a single “drive-thru” lane prior to the pay and pick-up window.
There will be approximately 350 feet (approximately 175 feet per lane) of
total queuing capacity from the “drive-thru” entrance to the two menu boards
and approximately 90 feet from the menu boards to the pick-up window,
providing a total drive-through queue length of approximately 440 feet and a

AM to 1:00 AM Sunday through Thursday and 9:00 AM to 3:30 AM Friday through Saturday. . .The proposed project

queueing capacity of approximately 20 vehicles (assuming 22 feet per
vehicle) from the beginning of the drive-through lanes to the pay and pick-up
window. Based on the “drive-thru” queuing data, the peak observed queue
was 17 vehicles; therefore, the proposed capacity would be able to
accommodate the expected peak demand.
As reported therein, the typical service time in the “drive-thru” lane at
“Raising Cane’s Restaurant” is 2½ minutes from the order board to the pick-
up window, with subsequent vehicles being processed at the pick-up window
every 35 to 40 seconds during the peak “drive-thru” periods. The traffic
engineer’s “general observations” included, but were not limited to:
► Spillovers outside the “drive-thru” lane occasionally occurred.
► Spillover was due to a delay at the order board. A more-than-average
delay at the order board (i.e., due to a large order or indecisiveness on
the part of the customer) briefly held up the movement of the queue,
sometimes causing the remainder of the queue to extend beyond the
“drive-thru” lane opening.
► Some customers were observed to pull into the site; evaluate the wait
time, based on the vehicle queue; and choose to park and go into the
building, rather than join the existing queue.
The above referenced traffic study concluded that a 4,047 GSF “fast-food
restaurant” (with “drive-thru”) translated into a 17-vehicle queuing capacity,
representing a ratio of 4.20 vehicles per 1,000 GSF.
With regards to the 2021 Proposed Revised BCBP, the owner, operator,
franchisee, licensee, and/or master leasee for the “retail/restaurant” (“QSR-1”)
building has not been identified, the operator(s) of the “fast-food restaurant” (with
“drive-thru”) and the additional unspecified “restaurants” (without “drive-thru”) are
not known. Since the precise division of the 6,500 GSF “retail/restaurant” (“QSR-
1”) building (“Parcel 2”) remains undetermined, pending that determination, the
requisite pre- or post-COVID-19 queuing capacity cannot be precisely derived.
With regards thereto, unknown and unspecified variables include: (1) the
estimated time from entry to exit of the “drive-thru” aisle; and (2) the minimum
queuing capacity of the proposed “drive-thru” aisle.
As illustrated in Figure A-2 (2021 Proposed Revised BCBP – Proposed “Fast-
Food Restaurant” Drive-Thru Queuing Capacity Diagram), the Applicant
depicting a queuing capacity of only about 13 vehicles prior to potential
interference with other on-site parking and circulation patterns. Based on the
separate distance between queuing vehicles, once operational, actual “drive-
thru” lane capacity may be less than that indicated.
Assuming that the 2,500 GSF “fast-food restaurant” (with “drive-thru”) proposed
as part of the “retail/restaurant” (“QSR-1”) building and no adjustments are made
for the accompanying proposed minimum 260 SF “outdoor dining area,” does
not exceed that square footage, based on the information derived from the above
referenced analyses of the proposed 3,885 GSF “In-N-Out Restaurant” in Rancho
Mirage (4.38 vehicles/1,000 SF), the 4,562 GSF “Chick-fil-A Restaurant” in
Monrovia (aggregate 4.93 vehicle/1,000SF), and the 4,047 GSF “Raising Cane’s
Restaurant” in Brea (4.20 vehicles/1,000 SF), although the length of the “drive-

thru” aisle is not identified, excluding the proposed minimum 260 SF of
accompanying “outdoor dining area,” the illustrated 13-vehicle queuing capacity
would be expected to reasonably accommodate that 2,500 GSF “drive-thru
restaurant” queuing capacity demands.
Based on the cited studies, based on an 85th percentile standard, presented in
Table A-12 (Variable “Drive-Thru” Queuing Demand Based on Restaurant Square
Footage) is a table depicting differences in queuing capacity based on different
square footage for “fast-food restaurants” (with “drive-thru”) that could be operated
within the proposed “retail/restaurant” (“QSR-1”) building (“Parcel 2”). Assuming
22 linear feet per standard-sized vehicle, presented therein is both the
recommended number of queuing vehicle capacity (rounded upward) and the total
length (single lane) or combined length (multiple lanes) of the “drive-thru.”

Public transit and bicycle mobility are separately addressed below.
◊ Public Transit. Foothill Transit provides public transit services in the project area.
As illustrated in Figure A-3 (Foothill Transit – Existing Bus Routes 482/495), the
following bus routes presently operate in the general vicinity of the project site:
Route 482 (Pomona – Rowland Heights – Puente Hills Mall via Colima Road) and
Route 495 (Industry Park & Ride – Downtown Los Angeles Express Services).
Although there are presently no bus stops along northbound Brea Canyon Road,
between the SR-60 Freeway and the Industry Metrolink Station (600 Brea Canyon
Road, Industry), a southbound bus stop exists along Brea Canyon Road north of
Lycoming Street. The 2021 Proposed Revised BCBP includes, as a component
to its transportation demand management plan, the provision of a new bus shelter
and new bus pad at the existing bus stop located along Brea Canyon Road to
north of the project site.
◊ Bicycle Mobility. With regards to the 1993/2013/2014 General Plan, as indicated
in the 2019 Approved BCBP/MND: “[T]he 1993/2013/2014 General Plan identified
a shared “Class III” bicycle route along Brea Canyon Road. As depicted in in the
“Los Angeles County Bicycle Master Plan,” Brea Canyon Road and Lycoming
Street (east of Brea Canyon Road) are designated as “Class III” bicycle routes.”

Additional references to the City’s “Recreational Trails and Bicycle Route Master
Plan” (2001) include:
Class II bikeways require a designated lane within the right-of-way for
bicycle travel. This designated lane must match the flow of traffic and be
a minimum of five feet in width. A number of Class II bikeways exist within
the City and additional Class II bikeways are identified as having future
potential for this designation.
Brea Canyon Road – A Class II bikeway is proposed from the northern
City limit to Pathfinder, a distance of 1.2 miles. This is a regional route
and provides access to a number of facilities, including the Metrolink
Train Station, and the Golden Springs and Pathfinder routes. South of
Pathfinder on the west side (southbound) it is a combination of Class IIII
for approximately 1.4 miles.
The proposed [2019 Approved BCBP] project includes no provisions or
other accommodations for any improvements to existing or proposed
bicycle facilities along the property’s Brea Canyon Road frontage.84
As indicated in the 2040 General Plan/CAP: “The City of Diamond Bar has made
a concerted effort to expand the ease of alternative transportation options for
residents, recognizing both health and environmental benefits. This includes the
introduction of bicycle facilities along roads such as Golden Springs Drive and
Brea Canyon Road.”85 As extracted therefrom, illustrated in Figure A-4 (2040
General Plan/CAP – Portion of Citywide Bicycle Network)86 is a map depicting the
“bicycle network” in the City.
A “Class IV – Protected Bike Lane” is identified along Brea Canyon Road,
extending from Golden Springs Road (on the south) to the Industry Metrolink
Station (600 Brea Canyon Road, Industry) (on the north). As defined therein:
Class IV Protected Bike Lanes, also referred to as cycle tracks or
separated bikeways, are bikeways for the exclusive use of bicycles that
are physically separated from vehicle traffic. Types of separation may
include, but are not limited to, grade separation, flexible posts, physical
barriers, or on-street parking.87
In compliance with Section 5.106.4.1.1 (Short-Term Bicycle Parking) in Chapter 5
(Nonresidential Mandatory Measures) of the 2019 CalGreen, the Applicant shall
provide permanently anchored bicycle racks equal to 5 percent of new visitor
motorized vehicle parking spaces, with a minimum of one two-bike capacity rack.
Other mandatory measures applicable to non-residential projects identified in
2019 CalGreen include:

o Section 5.106.5.2 (Designated Parking). In new projects or additions of
alterations that add 10 or more vehicular parking spaces, provide designated
parking for any combination of low-emitting, fuel efficient, and carpool/van
pool vehicles as shown on Table 5.106.5.2; and
o Section 5.106.5.3 (Electric Vehicle Charging). Construction shall comply with
Section 5.106.5.3.1 or 5.106.5.3.2 to facilitate future installation of electric
vehicle supply equipment.
Although designated on-site bicycle parking areas are provided, because the
current site plan does not explicitly accommodate bicycle route improvements
along Brea Canyon Road, the 2021 Proposed Revised BCBP would appear to
foreclose future opportunities to develop a “Class IV Protected Bike Lane
northbound along a segment of Brea Canyon Road. In so doing, the 2021
Proposed Revised BCBP appears to be potentially inconsistent with a number of
2040 General Plan/CAP policies. When a proposed action is found to be
consistent with a preponderance of general plan policies, potential
inconsistencies with certain policies presented therein is not, in and of itself,
deemed to constitute a significant environmental effect under CEQA.

(b) A resource determined by the lead agency, in its
discretion and supported by substantial
evidence, to be significant pursuant to criteria set
forth in Section 5024.1(c) of the Public
Resources Code. In applying the criteria set forth
in Section 5024.1(c) of the Public Resources
Code, the lead agency shall consider the
significance of the resource to a California
Native American tribe.
Preliminary Determination: Less-than-Significant Impact
Findings of Fact: On July 24, 2019, through written correspondence, the Department
provided government-to-government notification to those tribal contacts identified by the
NAHC. In response to the Department’s outreach efforts, the Gabrieliño Tongva Indians of
California Tribal Council and the Gabrieleno Band of Mission Indians - Kitz Nation responded
to the City’s invitation for tribal consultation. In a meeting conducted at City Hall (21810
Copley Drive, Diamond Bar), Department staff met with a representative of the Gabrieliño
Tongva Indians of California Tribal Council on August 22, 2019. In addition, Department staff
conducted a telephone conference with representatives of the Gabrieleno Band of Mission
Indians - Kitz Nation on September 5, 2019.
Tribal consultation concluded with the adoption of a number of mitigation measures (“MM-
8” through “MM-11”) designed to minimize potential impacts on tribal cultural resources. In
addition, as included in 2040 General Plan/CAP/FPEIR and as adopted by the Council
(Resolution No. 2019-43, December 17, 2019), “PMM-CULT-2” was identified by the
Department as being potentially relevant to the 2021 Proposed Revised BCBP.
A site-specific grading permit was issued for the 2019 Approved BCBP and rough grading
activities associated therewith have previously commenced. Although additional grading
activities associated with the 2021 Proposed Revised BCBP will occur, with the
commencement of rough grading activities, including the associated disturbance of the
entire project site, many of the project-level mitigation measures presented in the 2019
Approved BCBP/MND were effectively implemented and, based on that site disturbance,
would no longer appear to remain applicable to the 2021 Proposed Revised BCBP.
With the City’s issuance of a rough grading permit associated with the 2019 Approved BCBP,
project-level mitigation measure “MM-8,” “MM-9,” and “MM-10,” and program-level mitigation
Measure “PMM-CULT-2” were effectively implemented and no longer remain applicable to
the 2021 Proposed Revised BCBP. Because certain statutory and regulatory provisions
apply to all construction projects, those provisions, in the form of a mitigation measure (“MM-
11”), has been retained.
No further tribal consultation is required herein.

(e) Comply with federal, State, and local

Preliminary Determination: Less-than-Significant Impact
Findings of Fact: Relative to utilities and service systems, no project-level mitigation
measures were identified in the 2019 Approved BCBP/MND or adopted by the Council
(Resolution No. 2019-40, November 19, 2019). None of the program-level mitigation
measures included in the 2040 General Plan/CAP/FPEIR/MND and adopted by the Council
(Resolution No. 2019-43, December 17, 2019), appear directly relevant to the 2021
Proposed Revised BCBP.
Because all associated infrastructure improvements have or will be undertaken as
prerequisite components of the 2019 Approved BCBP, no additional new or expanded water,
wastewater, storm drain, or dry utility systems or facilities will be required to accommodate
the 2021 Proposed Revised BCBP.
Water, wastewater, and solid waste services and systems are separately addressed herein.
♦ Water. With regards to the 2019 Approved BCBP, a “will-serve” letter was received
from the Walnut Valley Water District (WVWD or District). Since the 2021 Proposed

Revised BCBP will add only an additional 385 GSF thereto, the Department has
determined that the existing “will serve” letter sufficiently serves to demonstrate the
available of adequate potable water resources to accommodate the proposed
development.
♦ Wastewater Treatment. With regards to the 2019 Approved BCBP, a “will-serve” letter
was received from the County Sanitation Districts of Los Angeles County (CSDLAC).
Since the 2021 Proposed Revised BCBP will add only an additional 385 GSF thereto,
the Department has determined that the existing “will serve” letter sufficiently serves to
demonstrate the available of adequate wastewater treatment capacity to accommodate
the proposed development.
♦ Solid Waste. “Solid waste” means all “solid waste” defined under Section 40191 of the
PRC, as amended, and includes discarded putrescible and non-putrescible solid,
semisolid, and liquid wastes, including refuse, construction and demolition debris,
recyclable materials, and green waste, or any combination thereof which are permitted
to be disposed of in a Class III landfill and which are included in the definition of “non-
hazardous solid waste” as set forth in the CCR.
Pursuant to Section 8.16.610 (Construction or Demolition Waste), Division 6
(Construction and Demolition Waste), Title 8 (Health and Safety) of the DBMC:
Every covered construction project shall divert at least 75 percent, measured
by weight, of all construction/demolition waste generated by the covered
construction project.
The 2021 Proposed Revised BCBP will add an additional 385 GSF to the project
examined in the 2019 Approved BCBP/MND, incrementally contributing to the quantity
of construction materials required for the project’s implementation and associated
construction/demolition (C&D) wastes associated therewith. “Covered construction
projects” include all “construction, demolition or remodel projects of 1,000 square feet
or more.” Compliance with Section 8.16.610 of the DBMC will reduce those C&D
wastes associated with the 2021 Proposed Revised BCBP to a less-than-significant
level.
The 2019 Approved BCBP/MND included detailed information concerning the
generation, handling, and disposal of hazardous and medical wastes but, absent a
“restaurant” component (excluding food service operations associated with the
proposed “hotel”), did not explicitly address organic wastes (e.g., food waste, green
waste, landscape and pruning waste, nonhazardous wood waste, and food-soiled
paper waste that is mixed in with food waste”). The presence of food wastes, including
putrescible wastes,88 as may be associated with the proposed “fast-food restaurant”
and accompanying “outdoor dining area,” including any litter resulting therefrom,
properly deposited in exterior receptacles but subsequently scattered therefrom or
improperly disposed of and remaining on the ground, may be evident even when the
proposed “fast-food restaurant” is closed and the proposed “outdoor dining area” is not
in active use.
88/ “Putrescible wastes” include “wastes that are capable of being decomposed by micro-organisms with sufficient
rapidity as to cause nuisances because of odors, vectors, gases or other offensive conditions, and include materials
such as, but not limited to food wastes, offal and dead animals” (CalRecycle, Short-Lived Climate Pollutants (S LCP):
Organic Waste Reduction, Final Regulation Text, November 2020).

With regards to the disposal of organic wastes, the following State statutes and
regulations are potentially relevant thereto and may dictate certain operational aspects
of the 2021 Proposed Revised BCBP:
◊ Assembly Bill 1826. As signed into law by Governor Brown in 2014, under
Assembly Bill (AB) 1836 (Mandatory Commercial Organics), by December 31,
2020, all commercial entities that producing more than 2 cubic yards (CY) of solid
waste a week are mandated to subscribe to an organic material hauling service
or divert organic materials from the landfill through some other means. “Solid
waste” means the entire generated waste stream, including garbage, recyclables,
and organic material. On January 1, 2022, the requirements of AB 1836 will be
eclipsed by those of Senate Bill (SB) 1383.
As defined therein: “’Organic waste’ means food waste, green waste, landscape
and pruning waste, nonhazardous wood waste, and food-soiled paper waste that
is mixed in with food waste.” As further defined therein: “’Self-hauler’ means a
business that hauls its own waste rather than contracting for that service and ‘self-
haul’ means to act as a self-hauler” (Section 42649.8, PRC).
Pursuant to AB 1826, qualifying businesses are required to participate in a
mandatory “commercial organics recycling program” that diverts organic waste
from landfill disposal. Businesses can meet AB 1826 requirement to recycle
organic waste by implementing one or more of the following options:
o Recycling organic waste on the site or by self-haul organic waste for organic
recycling;
o Selling or donating the generated organic waste; and/or
o Source separate organic waste from other wastes and subscribing to an
organic waste collection and recycling service through the local commercial
waste management provider.
◊ Senate Bill 1383. Organic materials comprise approximately 68 percent of
California’s disposed waste stream (based on the 2014 waste characterization
study).89 The decomposition of organic wastes contributes to methane gas
emissions. Adopted in 2016, beginning in 2022, SB 1383 set three goals relating
to methane reduction at operating landfills: (1) a 50-percent reduction in the level
of Statewide disposal of organic waste from the 2014 level by 2020; (2) a 75-
percent reduction in the level of Statewide disposal of organic waste from the 2014
level by 2025; and (3) a 20 percent increase in recovery of “edible food” (food that
could be consumed without harm by humans) for human consumption that would
otherwise be disposed. This is a Statewide goal that California must collectively
achieve and not a goal for individual jurisdictions to achieve.
Effective on January 1, 2022, SB 1383 require that all jurisdictions expand or
create an organics collection program, inclusive of all hauler agreement
negotiations, collection rates, and infrastructure capacity. The regulations also
requires jurisdictions to implement edible food recovery programs to help increase
food recovery throughout the State. As an alternative to recycling, commercial
edible food generators (including restaurants and other food product businesses)

shall sell or donate the maximum amount of their edible food that would otherwise
be disposed.
Under AB 1826, in order to divert organic waste generated by businesses, local
jurisdictions were required to implement an “organic waste recycling program” on
and after January 1, 2016.
◊ Assembly Bill 827. As signed into law by Governor Newsom in 2019, Assembly
Bill (AB) 827 (Commercial Organics and Recycling Bins) requires that commercial
food establishments provide bins to customers for collecting organics and
recycling alongside trash. Bins must be available to customers on or by July 1,
2020. “Full-service restaurants” are exempt as long as they provide organics and
recycling bins in the BOH for their employees.
“Full-service restaurants” are defined as those where: (1) customers are escorted
or assigned to an assigned eating area; (2) customers' food and beverage orders
are taken after being seated; (3) the food and beverage orders, as well as any
other requested items, are delivered directly to the customers; and (4) the check
is delivered directly to the customer at the assigned eating area.
The City has executed exclusive franchise agreements with Waste Management (WM)
and Valley Vista Services (VVS). VVS is the City’s contracted waste hauler for
multifamily (five or more units) and commercial operations. VVS is required to comply
to all State and local regulations regarding the collection, recycling, diversion, and
disposal of “commercial solid wastes.” As defined in Section 17225.12, Title 14, of the
CCR: “commercial solid wastes” include “all types of solid wastes generated by stores,
offices and other commercial sources, excluding residences, and excluding industrial
wastes.”
Unless otherwise authorized or directed, VVS is assumed to be responsible for the
collection of those organic wastes, green wastes, food wastes, and food-soiled paper
wastes generated by those restaurant-related uses operating from the
“retail/restaurant” (“QSR-1”) building (“Parcel 2”).
With regards to the 2021 Proposed Revised BCBP, the commercial trash receptacles
most closely associated with the proposed “retail/restaurant” uses are located directly
adjacent to the property’s northern property line, separated from proximal residences
(21052-21058 Lycoming Street) only by the existing 50-foot-wide County flood control
channel. Specific to the 2021 Proposed Revised BCBP, based on the proposed
disposal of organic wastes, green wastes, food wastes, and food-soiled paper in close
proximity to existing residential receptors, including the potential for such actions to
generate odors and attract vectors.
If distinct from general wastes, the architectural plans accompanying the 2021
Development Application (G/A/A Architects, September 8, 2021) neither reference nor
illustrate the placement of any proposed “organic recycling bins/containers.”
Most commercial business utilize “roll-off” bins (dumpsters) as their collection points for
solid wastes generated on those sites. Commercially available dumpsters come in
different sizes (e.g., 2-8 CY). The larger the dumpster, the greater capacity thereof. As
illustrated in Figure A-5 (Proposed Trash Enclosures [September 8, 2021]), each of the
proposed three buildings include separate trash enclosures.

that may result in temporary or ongoing impacts
to the environment?
(d) Expose people or structures to significant risks,
including downslope or downstream flooding or
landslides, as a result of runoff, post-fire slope
instability, or drainage changes?
Preliminary Determination: No Impact
Findings of Fact: Relative to wildfires, no project-level mitigation measures were identified
in the 2019 Approved BCBP/MND or adopted by the Council (Resolution No. 2019-40,
November 19, 2019). None of the program-level mitigation measures included in the 2040
General Plan/CAP/FPEIR/MND and adopted by the Council (Resolution No. 2019-43,
December 17, 2019), appear directly relevant to the 2021 Proposed Revised BCBP.
On November 5, 2020 (Ordinance No. 02[2020]),90 the Council amended the DBMC and
adopted Title 32 (Fire Code) of the “Los Angeles County Code” which constitutes an
90/ Ordinance No. 02(2020) – An Ordinance of the City Council of the City of Diamond Bar Amending Title 15 of
the Diamond Bar City Code and Adopting, by Reference, Title 32, Fire Code, of the Los Angeles County Code, as
Amended which Constitutes an Amended Version of the California Fire Code, 2019 Edition.

amended version of the “California Fire Code, 2019 Edition” (2019 CFC). As indicated in
Title 16 (Fire Safety), Chapter 16 (Fire Code), Section 16.00.010 (Adopted), therein:
Except as hereinafter provided, Title 32, Fire Code, of the Los Angeles County
Code, as amended and in effect on April 10, 2020, which constitutes an amended
version of the California Fire Code, 2019 Edition (Part 9 of Title 24 of the California
Code of Regulations), Chapters 1 through 80, Appendix O, P, Q, and R, and
excluding all other appendices of the 2019 Edition of the California Fire Code with
errata, and adopting and incorporating herein by reference into Title 32 of the Los
Angeles County Code, the 2018 Edition of the International Fire Code, Chapters 1
through 7, Chapters 9 and 10, Chapter 12, Chapters 20 through 37, Chapters 50
and 51, Chapters 53 and through 56, Chapters 59 through 67, Chapter 80,
Appendix O, P, Q, and Appendix R is hereby adopted by reference and shall
constitute and may be cited as the Fire Code of the City of Diamond Bar.
As defined in Chapter 2 (Definitions) of the 2019 CFC (Title 24, Part 9, CCR), a “wildfire risk
area” is defined as “[l]and that is covered with grass, grain, brush or forest, whether privately
or publicly owned, which is so situated or is of such inaccessible location that a fire
originating upon it would present an abnormally difficult job of suppression or would result in
great or unusual damage through fire or such areas designated by the fire code official.” The
2019 CFC imposes specific requirements and limitation within those areas.
Based on consistent Statewide criteria addressing the severity of fire hazards expected to
prevail, the California Department of Forestry and Fire Protection (CalFire) has identified
“Fire Hazard Severity Zones” (FHSZs) throughout the State. FHSZs are geographic areas
designed pursuant to Sections 4201-4204 of the PRC in State Responsibility Areas (SRAs)
or, pursuant to Sections 51175-51189 of the CGC, in Local Responsibility Areas (LRAs), as
local agency “Very High Fire Hazard Severity Zones” (VHFHSZs).
SRAs are areas where the State is financially responsible for the prevention and suppression
of wildland fires. SRAs do not include lands within incorporated city boundaries or federally
owned lands. LRAs include incorporated cities, cultivated agriculture lands, and portions of
the desert. In LRAs fire protection is typically provided by municipal fire departments, fire
protection districts, counties, and by CalFire under contract to local government.
Presented in Figure A-6 (Very High Fire Hazard Severity Zones – City of Diamond Bar
[September 2011]) are CalFire’s recommended VHFHSZ areas located in the City’s LRA.
As noted, the project site is designated a “non-VHFRSZ.” As a result, with regards to the
2021 Proposed Revised BCBP, no wildfire impacts have been identified.

Preliminary Determination: Less-than-Significant Impact
Findings of Fact: Based on information now known to the Department, no additional
environmental impacts, beyond those disclosed herein have been identified by the Lead
Agency, which have the potential to affect this CEQA-based analysis.
Based on the information and analysis provided herein, there exists no evidence suggesting
that the 2021 Proposed Revised BCBP would substantially reduce the habitat of a fish or
wildlife species, cause a fish or wildlife population to drop below self-sustaining levels,
eliminate a plant or animal community, substantially reduce the number or restrict the range
of a rare or endangered plant or animal, or eliminate important examples of the major periods
of California history or prehistory.
As indicated in the National Park Service’s (NPS) “National Register of Historic Places
Program”91 and California State Parks - Office of Historic Preservation’s (OHP) “California
Historic Resources, Orange County,”92 the project site has not been listed or been
determined eligible for listing in a State or federal register of historic resources.
No potentially significant cumulative impacts have been identified. Additionally, all potential
impacts to human beings do not elevate to a level of significance under CEQA.
Additional References: None
Pursuant to Section 15164(b) of the State CEQA Guidelines: “An addendum to an adopted
negative declaration may be prepared if only minor technical changes or additions are necessary
or none of the conditions described in Section 15162 calling for the preparation of a subsequent
EIR or negative declaration have occurred.”93 An “addendum need not be circulated for public
review” but can be included in or attached to an adopted negative declaration (Section 15164[c],
State CEQA Guidelines).
It is the Department’s preliminary conclusion that the proposed project, as revised, does not
trigger the need to commence the preparation of a subsequent or supplemental EIR or to prepare
a subsequent MND and that only minor technical changes and additions to the 2019 Approved
BCBP/MND are necessary (Section 21166, CEQA; Section 15162, State CEQA Guidelines). As
evidenced by these preliminary findings, the Department presents this 2021 Proposed Revised
BCBP/Addendum for consideration by the Lead Agency’s decision-making bodies.
In support of the utilization of “addendum” as the appropriate instrument for the demonstration
of CEQA compliance, the City’s decision-making body shall make the following findings:
91/ National Park Service, National Register of Historic Places Program (http://www.nps.gov/nr/research/).
92/ California State Parks, Office of Historic Preservation, California Historic Resources, Orange County
(http://ohp.parks.ca.gov/ListedResources/?view=county&criteria=30).
93/ In Friends of the College of San Mateo Gardens v. San Mateo Community College District (2016), the
California Supreme Court reaffirmed that addenda can appropriately be used to consider modifications to a previously
approved negative declaration.

Subject: Revised Parking Demand Analysis Addendum for
Brea Canyon Business Center
Diamond Bar, California
Dear Mr. Chan:
As requested, Linscott, Law, & Greenspan, Engineers (LLG) is pleased to submit this
Revised Parking Demand Analysis Addendum associated with the Brea Canyon
Business Center (herein referred to as Project). The addendum report has been
prepared to assess the parking implications associated with the revised Project
description, as of April 2021. This addendum report uses the previously approved
Revised Parking Demand Analysis for Brea Canyon Business Park prepared by LLG
Engineers, dated January 25, 2019, as a database and reference.
The Project site is a 5.73-acre triangular shaped parcel of land located along the
eastside of Brea Canyon Road north of the SR-60 freeway in the City of Diamond
Bar, California. The Project site is currently developed and is utilized as a RV and
boat storage facility. Access to the subject property is provided via an existing
driveway on Brea Canyon Road, located approximately 125-feet north of the SR-60
WB Ramps.
Brea Canyon Business Center is a mixed-use center with a total floor area of 118,387
square-feet (SF) within three (3) buildings. The approved 1 mix of uses includes a
109-room, 61,743 SF, four-story limited services business hotel (H1) to be occupied
by Hilton Hampton Inn & Suites, a three-story, 47,828 SF office/medical office
building (O1) with 31,998 SF of office use and 15,830 SF of medical office use, and
an 8,900 SF medical office building (O2).

Revised Brea Canyon Business Center Shared Parking Addendum, Diamond Bar 1-10-22.doc
The proposed Project description has been updated and now includes a 124-room,
64,245 SF, four-story limited services business hotel (H1) to be occupied by Hilton
Hampton Inn & Suites, a three-story, 47,642 SF medical office building (O1), and a
6,500 SF quick-service retail building (QSR-1) with 4,000 SF of restaurant use and
2,500 SF of fast-food restaurant with drive-thru use. In addition, a patio area of 260
SF is proposed to support the food uses.
Pursuant to the City of Diamond Bar requirements, a parking study addendum is
required to evaluate the parking requirements of the Project Options and to ensure
that adequate parking is provided for the proposed mix of uses. The parking analysis
evaluates the Project’s parking requirements based on the City of Diamond Bar
Municipal Code as well as the methodology outlined in the Urban Land Institute’s
(ULI) Shared Parking, 2nd Edition, consistent with Section 22.30.050 – Reduction of
off-street parking requirements for shared use of the City’s Municipal Code.
The addendum study focuses on the following:
Calculates the Code-based parking requirements for Project based on the
application of City Code parking ratios.
Estimates parking demand through the application of the Shared Parking
concept.
Our method of analysis, findings, and recommendations are detailed in the following
sections of this report. Briefly, we find the following:
The proposed parking supply on the site totals 289 spaces.
A “code” calculation for the proposed center requires 396, resulting in a
theoretical code-calculated parking shortfall of 107 spaces.
A shared parking analysis for the proposed center using city code ratios along
with ULI parking profiles, and empirical data derived for the Hotel component
of the Project, yields a maximum peak weekday parking demand of 289
spaces that when compared to the 289 provided spaces results in a balanced
condition; the weekend peak parking demand totals 278 spaces, which results
in a surplus of 11 spaces (See Tables 3 and 4).

driveway on Brea Canyon Road, located approximately 125-feet north of the SR-60
WB Ramps. Figure 1, located at the rear of this letter report, presents a Vicinity
Map, which illustrates the general location of the Project site in the context of the
surrounding street system.
Brea Canyon Business Center is a mixed-use center with a total floor area of 118,387
square-feet (SF) within three (3) buildings. The approved 2 mix of uses includes a
109-room, 61,743 SF, four-story limited services business hotel (H1) to be occupied
by Hilton Hampton Inn & Suites, a three-story, 47,828 SF office/medical office
building (O1) with 31,998 SF of office use and 15,830 SF of medical office use, and a
8,900 SF medical office building (O2).
The revised Project now includes a 124-room, 64,245 SF, four-story limited services
business hotel (H1) to be occupied by Hilton Hampton Inn & Suites, a three-story,
47,642 SF medical office building (O1), and a 6,500 SF quick-service retail building
(QSR-1) with 4,000 SF of restaurant use and 2,500 SF of fast-food restaurant with
drive-thru use. In addition, a patio area of 260 SF is proposed to support the food
uses.
The proposed Hilton Hampton Inn & Suites hotel will provide limited services as no
restaurant and limited to no meeting/conference space is available for use in this
hotel, thus reducing the occupancy of the guests during the day. It is an extended stay
product with built in kitchenettes with very low turnover rate. The staff will be
minimal for an extended stay product as the rooms will not have to be cleaned as
frequently.
The following summarizes the square footages for the Approved Project and the
updated Proposed Project:

proposed uses and associated floor areas for Brea Canyon Business Center for the
proposed Project.
Figure 2 presents the proposed conceptual site plan which highlights the proposed
buildings and parking areas prepared by GAA Architects.
Parking Supply
The proposed on-site parking supply for the Project totals 289 spaces, consisting of
204 standards stalls, 53 compact spaces, 8 handicap accessible spaces, and 24
EV/CA/CP stalls. It should be noted that the 53 compact spaces which comprises
18% of the total supply (53 ÷ 289 x 100% ≈ 18%). The City’s Municipal Code allows
for up to 20% compact. As such, the proposed compact spaces adequately satisfies
the City requirement. As it relates to EV/CA/CP stalls the Project is proposing to
construct 24 spaces which comprises 8% of the parking supply (24 ÷ 289 x 100% ≈
8%). This requirement is consistent with the approved project which was based on the
2019 California Green Building Standards Code, developments with over 201 spaces
have a minimum requirement of 8% EV/CA/CP. Review of the Project site plan
indicates that the handicap accessible stalls as well as the EV/CA/CP stalls are
distributed evenly throughout the site and are located near the front entrance of
Buildings O1 and QSR-1 as well as Building H1. Relative to the proposed compact
spaces, approximately 45 of these spaces are located in the site’s easterly parking lot,
east of Building O1. In addition to the proposed 289 spaces, four (4) loading spaces
will be provided of which one (1) loading space is proposed adjacent to Building
QSR-1, two (2) loading spaces adjacent to Building O1 and one (1) loading space
adjacent to Building H1. The number of loading spaces is consistent with the
requirements documented in Section 22.30.100 Off Street Loading Space
Requirement in the City’s Municipal Code. It should be noted that City code does not
identify a loading space requirement for hotel uses. However, it our understanding the
GAA Architects worked directly with the Planning Department Staff and Director to
agree that one (1) loading space for the hotel would be appropriate. It should be
noted that the proposed on-site parking supply of 289 spaces has been utilized to
assess the parking requirements for the proposed Project.

PARKING SUPPLY-DEMAND ANALYSIS
This parking analysis for the Project involves determining the expected parking
needs, based on the size and type of proposed development components, versus the
parking supply. Typically, there are two methods that can be used to estimate the
site’s peak parking needs. These methods have been used in this analysis and
include:
Application of City code requirements (which typically treats each tenancy
type as a “stand alone” use at maximum demand).
Application of shared parking usage patterns by time-of-day (which
recognizes that the parking demand for each tenancy type varies by time of
day and day of week). The shared parking analysis starts with a code
calculation for each tenancy type.
The shared parking methodology is concluded to be applicable to a development such
as Brea Canyon Business Center because the individual land use types (i.e., hotel,
office, etc.) experience peak demands at different times of the day.
CODE PARKING REQUIREMENTS
The code parking calculation for proposed Project is based on the City’s requirements
as outlined in Chapter 22.30 – Off-Street Parking and Loading Standards of the City
of Diamond Bar Municipal Code. The City’s Municipal Code specifies the following
parking requirements for the Project:
Hotels and Motels: 1 space/guest room, plus 1 space for each 2 employees on
largest shift, plus required spaces for accessory uses.
Clinics, Medical/Dental Offices: 1 space per 250 SF of GFA.
Restaurants, fast food: 1 space for each 100 SF of GFA, plus 1 space for each
100 SF of outdoor dining area.
Table 2 summarizes the parking requirements for the proposed Project using the above-
referenced City code parking ratios. As shown, direct application of City code parking
ratios to the Project results in a total parking requirement of 396 spaces. With a
proposed on-site parking supply of 289 spaces, a theoretical parking deficiency of 107
spaces is forecast.
However, as previously mentioned, there is an opportunity to share parking spaces based
on the utilization profile of each land use component. Consistent with Section
22.30.050 – Reduction of off-street parking requirements for shared use of the

Municipal Code, the following section calculates the parking requirements for the
proposed Project based on the shared parking methodology approach.
SHARED PARKING ANALYSIS
Shared Parking Methodology
Accumulated experience in parking demand characteristics indicates that a mixing of
land uses results in an overall parking need that is less than the sum of the individual
peak requirements for each land use. Due to the proposed mixed-use characteristics
of the Project, opportunities to share parking can be expected. The objective of this
shared parking analysis is to project the peak parking requirements for the project
based on the combined demand patterns of different land uses at the site.
Shared Parking calculations recognize that different uses often experience individual
peak parking demands at different times of day, or days of the week, or even months
of the year. When uses share a common parking footprint, the total number of spaces
needed to support the collective whole is determined by adding parking profiles (by
time of day, week, and year), rather than individual peak ratios as represented in
Chapter 22.30 – Off-Street Parking and Loading Standards of the City of Diamond
Bar Municipal Code.
There is an important common element between the traditional "code" and the Shared
Parking calculation methodologies; the peak parking ratios, or "highpoint" for each
land use's parking profile, typically equals the "code" parking ratio for that use. The
analytical procedures for Shared Parking Analyses are well documented in the Shared
Parking, 2nd Edition publication by the Urban Land Institute (ULI).
Shared parking calculations for the Project utilize hourly parking accumulations
developed from field studies of single developments in free-standing settings, where
travel by private auto is maximized. These characteristics permit the means for
calculating peak parking needs when land use types are combined. Further, the
shared parking approach will result, at other than peak parking demand times, in an
excess amount of spaces that will service the overall needs of the project.
Key inputs in the shared parking analysis for each land use include:
Peak parking demand by land use for visitors and employees.
Adjustments for alternative modes of transportation, if applicable.
Adjustment for internal capture (captive versus non-captive parking demand),
if applicable.

Please note that for this analysis, no monthly adjustment factors to account for variations
of parking demand over the year and no internal capture adjustments were applied to
provide a conservative parking demand forecast.
Shared Parking Ratios and Profiles
The hourly parking demand profiles (expressed in percent of peak demand) utilized in
this analysis and applied to the Project are based on profiles developed by the Urban
Land Institute (ULI) and published in Shared Parking, 2nd Edition.
The hotel profiles that were developed and utilized in the ULI are more consistent for
hotels with a variation of amenities inclusive of restaurants, meeting/banquet rooms,
and conference space. Appendix A provides further detail of the Hotel uses analyzed
within the ULI. Due to the proposed Hilton Hampton Inn & Suites Hotel providing
limited services with no restaurant use and no meeting/conference space, it is more
appropriate to utilize empirical parking ratios and parking profiles from a similar type
hotel-use. The parking ratio and hourly parking profiles utilized for the proposed
hotel component of the Project was derived using empirical data from actual observed
parking demand counts at an existing Hilton Hampton Inn Hotel conducted by
National Data and Surveying Services (NDS) on Thursday, November 8, 2018 and
Saturday, November 10, 2018. These parking demand counts were collected at a
Hilton Hampton Inn located in the City of Chino Hills, north of Chino Avenue and
west of the SR-71 in the Crossroads Shopping Center, between 8:00 AM and 10:00
PM. During these count days, the occupancy of the Hampton Inn was 84% during the
Thursday count and 90% during the Saturday count.
Based on an observed peak parking demand of 56 spaces (which occurred at 9:00 PM
on Thursday), an empirical peak parking demand rate of 0.64 spaces per occupied
room was calculated. In order to reflect peak-June hotel characteristics, per ULI
Shared Parking, a seasonal adjustment factor was applied which translates to a
“design” ratio of 0.79 spaces per occupied room. Appendix B contains the empirical
parking demand data for the Chino Hills Hilton Hampton Inn Hotel. This empirical
data provides justification that the peak demand experienced at business hotels are
much less when compared to the application of City Code requirement to the ULI

hotel parking profiles. Therefore, the empirical parking ratios and profiles derived
from the Chino Hills Hilton Hampton Inn Hotel were utilized for the hotel component
of the proposed Project.
For medical office uses, the parking profile in the ULI publication was used and
applied to the City’s Parking Code ratio of 1 space 250 SF of floor area to forecast
weekday and weekend hourly demand. Peak demand for medical office uses occurs
between 10:00 AM–12:00 PM and 2:00 PM–4:00 PM on weekdays, and 10:00 AM–
12:00 PM on weekends.
The ULI Shared Parking publication includes several categories for restaurants. For
this analysis, the parking profiles for family and fast-food restaurant-uses were
utilized. Like the retail profiles, the restaurant profiles are derived exactly from the
ULI baseline. The peak-parking ratio for restaurant uses exactly equals the City’s
Parking Code requirement of 1 space per 100 SF of floor area. Peak demand for
family restaurant uses occurs between 12:00 PM–1:00 PM on both weekdays and
weekends. Peak demand for fast food restaurant uses occurs between 12:00 PM-2:00
PM on both weekdays and weekends.
Application of Shared Parking Methodology
Tables 3 and 4 present the weekday and weekend parking demand for the Brea
Canyon Business Center Project based on the shared parking methodology. Columns
(1) through (4) of these tables present the parking accumulation characteristics and
parking demand of Brea Canyon Business Center for the hours of 6:00 AM to
midnight. Column (5) presents the expected joint-use parking demand for the entire
site on an hourly basis, while Column (6) summarizes the hourly parking
surplus/deficiency for the proposed project compared to a parking supply of 289
spaces.
Based on our experience, the shared parking approach summarized in Tables 3 and 4
are believed to be the most appropriate in evaluating the parking supply-demand
relationships for Brea Canyon Business Center. The results in these tables are the
focus of this parking investigation and recommendations. As noted earlier, for this
parking analysis, no monthly adjustment factors to account for variations of parking
demand over the year and no internal capture adjustments were applied to provide a
conservative parking demand forecast.
Shared Parking Analysis Results and Conclusions
Review of Table 3 shows that the peak-parking requirement for Brea Canyon
Business Center Project Option A during a weekday occurs between 2:00 PM – 3:00

PM and totals 289 spaces. On a weekend day, the peak parking requirements for the
proposed Project occurs at 10:00 AM, when a parking demand of 278 spaces is
forecast (see Table 4).
Based on the proposed shared parking supply of 289 spaces, a surplus of 0 spaces and
11 spaces would result during the weekday and weekend peak hours, respectively.
Figures 3 and 4 graphically illustrate the weekday and weekend hourly parking
demand forecast for the proposed Project, respectively. Each land use component and
its corresponding hourly Shared Parking demand for various mixes of uses, which
were presented in Tables 3 and 4, are depicted in these two figures relative to a shared
parking supply of 289 spaces. A review of these figures indicate that the mix-use
center’s available parking supply of 289 spaces will adequately accommodate Brea
Canyon Business Center’s weekday and weekend hourly shared parking demand.
Appendix C contains the shared parking analysis calculation worksheets for this
weekday and weekend day parking scenarios.
Given these results of above, we conclude that there is adequate parking on site to
accommodate the proposed tenant mix for Brea Canyon Business Center. It is expected
that the implementation of recommendations outlined in the approved Parking
Management Plan for the Brea Canyon Business Center, dated January 17, 2020, will
ensure that adequate parking will be provided for customers and employees of the
proposed medical office and retail/restaurant uses, as well as hotel guests and
employees. The approved PMP outlines the proposed allocation of parking supply on
site and key parking management strategies to maximize the availability of parking
for customers and employees of the Center.
SUMMARY OF FINDINGS AND CONCLUSIONS
1. Brea Canyon Business Center is a mixed-use business center composed of three
(3) buildings located in Diamond Bar, California and has a proposed supply of
289 spaces. The proposed mix of uses consists of a 124-room, 64,245 SF, four-
story limited services business hotel (H1) to be occupied by Hilton Hampton Inn
& Suites, a three-story 47,642 SF medical office building (O1), and a 6,500 SF
quick-service retail building (QSR-1) with 4,000 SF of restaurant use and 2,500
SF of fast-food restaurant with drive-thru use. In addition, a patio area of 260 SF
is proposed to support the food uses.

2. Direct application of City parking codes to the proposed uses at Brea Canyon
Business Center results in a total parking requirement of 396 spaces. With a
proposed on-site parking supply of 289 spaces, a theoretical code-calculated
parking deficiency of 107 spaces is forecast.
3. Given the mix of center tenancies, a shared parking analysis has been prepared and
indicates that the proposed parking supply at Brea Canyon Business Center will be
sufficient to meet the projected peak parking demands for the center. The weekday
would result in a balanced condition while the weekend would have a surplus of 11
spaces.
