and west sides of the building, and is enclosed by wrought iron railing and an open
metal trellis framework. Furnishings within the patio area include decorative tables,
chairs, waste receptacles, large potted plants, and umbrellas. Access to the outdoor
dining areas is provided via an existing ADA-compliant walkway located adjacent to the

PROJECT DESCRIPTION:
The applicant is requesting an amendment to the previously -approved Minor
Conditional Use Permit to allow ancillary hookah service in the front portion of the
outdoor dining area. A hookah is a water pipe device of Middle Eastern origin that is
used to smoke shisha, which is flavored tobacco (a mixture of tobacco, dried fruits and
molasses) or a non-tobacco-based substitute. The smoke is filtered through water at
the base of the hookah pipe.
Changes to the building exterior are not proposed as part of this application, except for
the removal of unpermitted canopy coverings on top of the decorative metal trellis
structures. The applicant is proposing to provide additional outdoo r patio furniture in the
front of the outdoor dining area to accommodate hookah service. The side portion of
the outdoor dining area that wraps around the west side of the building will not have
hookah service. The hookah preparation area will be located at the rear of the building,
away from food preparation areas.

ANALYSIS:
Review Authority (DBMC Section 22.56)
A Minor Conditional Use Permit (MCUP) is intended to allow for uses as identified in the
various zoning districts whose effect on the surrounding area cannot be determined
before being proposed for a particular location. MCUPs are normally subject to
approval of the City’s Hearing Officer (typically the Community Development Director).
However, because the previously-approved MCUP and Variance were reviewed and
approved by the Planning Commission, the requested amendment to the MCUP is
subject to review and approval by the Planning Commissio n (i.e., the highest review
authority).
When reviewing a 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 publi c 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.
When a MCUP is approved, it runs with the land and all conditions placed on the MCUP
are binding on all successors in interest. In other words, if the owner were to close the
business, a new tenant could locate in the space and operate the same type of
business. The new tenant would be required to comply with the same conditions as the
previous tenant and would not be permitted to expand the business without full review
and approval by the Planning Commission.
Required Parking
The required number of parking spaces for a restaurant is one space for every
75 square feet of indoor gross floor area for patrons, p lus one space for each
300 square feet of service area, plus one space for each 100 square feet of outdoor
dining area.
The existing restaurant with the outdoor dining area requires a minimum of 40 parking
spaces. There are currently 40 parking spaces, including three ADA parking spaces
provided on-site. The applicant is not proposing to expand the footprint of the existing
outdoor dining areas. The subject site continues to be in compliance with the minimum
number of required parking spaces for the res taurant and outdoor dining area by
providing 40 spaces.

Compatibility with Neighborhood
The project site is surrounded by an outdoor retail store (Diamond Fresh Farmers
Market) to the east, a service station (Mobil) with a drive-thru carwash to the west, fast
food restaurant (In-N-Out) with outdoor dining to the north, and single-family residences
to the south. The restaurant already has an existing outdoor dining area. In addition,
the existing outdoor sales area of Diamond Fresh Farmers Market abuts the residences
to the south, and the Mobil service station and drive-thru carwash are operating later
than Jasmine Grill. Therefore, the existing residences are already subject to noise and
activity associated with the existing and adjacent uses. The proposed request to allow
hookah service is ancillary to the primary restaurant and outdoor dining uses and will
have a negligible effect on existing noise and activity levels in the vicinity.
The project site is also located near a busy intersection of two major arterials, Golden
Springs Drive and Brea Canyon Road, with noise levels at 70 decibels according to the
Diamond Bar General Plan 2040 Environmental Impact Report. The SR -60 freeway is
also in close proximity and is a major contributor to ambient noise levels.
Furthermore, there will be no additional visual and privacy impacts generated from the
proposed hookah services since there are existing block walls and dense landscaping
at the rear of the property which provides screening. The operating characteristics will
have minimal impacts, if any, and are compatible with the existing and future uses in the
surrounding area as conditioned through the amendment to the MCUP.
Smoking
Under California State law, hookah falls under the definition of a tobacco product, and is
subject to the same regulations that apply to the smoking of other tobacco products in
outdoor dining areas. Although local jurisdictions may enact additional outdoor smoking
restrictions, the Diamond Bar Municipal Code currently does not contain such
restrictions.
7.1
Packet Pg. 21
Amendment to Minor Conditional Use Permit and Variance No. PL2019-122
Page 10 of 11
State regulations regarding smoking primarily address employee health in the
workplace, and do not, generally, address the health of the public at large. For
instance, it is against State law to smoke or use electronic smoking or vaping devices,
such as e-cigarettes, in an enclosed space at a place of employment or owner-operated
business. State law bans smoking within 20 feet of the entrance or operable window of
a public building, which is defined as a building owned and occupied, or leased and
occupied, by the state, a county, a city, a city and county, or a California community
college district. State law also prohibits smoking within 25 feet of playgrounds and tot
lots. Generally speaking, California regulations permit outdoor smoking lounges with
food service, and prohibit indoor smoking lounges with food service.
No type of entertainment, including live or recorded music, is proposed by the applicant.
The applicant is proposing to limit hookah service to the north (front) portion of the
existing outdoor dining area, which will mitigate potential noise and odor impacts to the
residences to the south. Given the location of the proposed hookah service area, it is
unlikely that the addition of hookah service in conjunction with outdoor dining would be
a nuisance to the surrounding residences.

B. RESOLUTION
NOW, THEREFORE, it is found, determined and resolved by the Planning Commission
of the City of Diamond Bar as follows:
1. The Planning Commission hereby specifically finds that all of the facts set forth
in the Recitals, Part A, of this Resolution are true and correct.
2. The Planning Commission hereby determines the Project to be Categorically
Exempt from the provisions of the California Environmental Quality Act (CEQA)
pursuant to the provisions of Article 19, Section 15301 (Existing Facilities) of the
CEQA Guidelines. Therefore, no further environmental review is required.
C. FINDINGS OF FACT
Based on the findings and conclusions set forth herein and as prescribed under
Diamond Bar Municipal Code (DBMC) Section s 22.54 and 22.56, this Planning
Commission hereby finds and approves as follows:
Minor Conditional Use Permit Review 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 outdoor dining area is
permitted in the Community Commercial (C-2) zone with the approval of a Minor
Conditional Use Permit. On December 10, 2019, the Planning Commission
adopted Resolution No. 2019-20 approving a Variance to allow the reduction of
the distance separation between the outdoor dining area and existing residential
uses to 85 (where 200 feet is required) and a Minor Conditional Use Permit to
allow outdoor dining at an existing restaurant. The applicant is proposing to serve
hookah in the front (north) existing outdoor dining area in conjunction with dining
service. As conditioned, the Proposed Use 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. 25
3
PC Resolution No. 2021-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
outdoor dining area at the restaurant is considered a service use and as such is
consistent with the General Plan.
The Proposed Use is consistent with General Plan Goal ED -G-3: (“Support the
retention, rehabilitation, and/or expansion of existing businesses, and the
attraction of new businesses”) in that the Proposed Use is a n accessory use to
the restaurant and outdoor dining uses and is being proposed to be located in the
north (front) outdoor dining area of the existing restaurant.
The Project site is not subject to the provisions of any specific plan.
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 Proposed Use will be located within the existing 1,007 square-foot north
(front) outdoor dining area of the existing 3,871 square-foot restaurant. The north
(front) existing outdoor dining area faces Golden Springs Drive and is situated
away from single-family residences to the south. Furthermore, there will be no
additional visual and privacy impacts generated from the existing outdoor dining
area since there are existing block walls and dense landscaping at the rear of the
property which provides screening for the single-family residential properties to
the south. The existing outdoor dining area is clearly and physically defined by
an existing decorative metal trellis and potted plants to complement the building
exterior. Therefore, the physical appearance of the restaurant and the
surrounding area will be compatible.
Additionally, the operating characteristics will be compatible with the existing
uses of the surrounding area. The existing restaurant operation are Wednesdays
through Monday from 10:30 a.m. to 9:00 p.m. and closed on Tuesdays. There is
no alcohol service provided, and the hookah service will be accessory to the
primary restaurant use. The existing restaurant with outdoor dining complies with
the City’s Development Code parking requirement.
Through compliance with the conditions of approval stipulating the manner in
which the use must be conducted, the Proposed Use will be compatible with the
surrounding neighborhood.
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 Proposed Use is physically suitable within the subject site because it is an
ancillary use and will be located in the existing outdoor dining area at the north
(front) of the restaurant. The applicant is not proposing any additional square
7.1.a
Packet Pg. 26
4
PC Resolution No. 2021-XX
footage, expansion of outdoor dining area, and modifications to the building
exterior. In addition, the Proposed Use will be using existing access and parking.
The existing restaurant has 40 on-site parking spaces. The Proposed Use will
not increase the number of required parking and is not expanding the use of the
space.
The Proposed Use is physically suitable at the subject site because it is being
proposed in an existing restaurant’s existing outdoor dining area facing Golden
Springs Drive and situated away from single-family residences to the south. The
Proposed Use is ancillary to the primary restaurant use . Given the proposed
hours of operation, parking supply, and the types of adjoining uses, it is
reasonable to conclude that the Proposed Use will be compatible with the other
uses in the neighborhood.
5. Granting the Minor 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 of approval within the attached resolution, and the Building and
Safety Division.
6. The proposed Project has been reviewed in compliance with the provisions of the
California Environmental Quality Act (CEQA).
The proposed use is categorically exempt from the provisions of the California
Environmental Quality Act (CEQA) as set forth under Article 19 Section 15301
(Existing Facilities) of the CEQA Guidelines.
Variance Findings (DBMC Section 22.54.040)
The Use is hereby determined to be ancillary to the existing outdoor dining area. As
such, the Variance findings previously made under Resolution No. 2019-20 are
unaffected by the Use, remain fully valid, and are incorporated he rein by reference.
D. CONDITIONS OF APPROVAL
Based upon the findings and conclusion set forth above, the Planning Commission
hereby approves the Amendment to Minor Conditional Use Permit and Variance No.
PL2019-122 subject to the following conditions:
1. This approval is to allow the existing restaurant to provide hookah service in
conjunction with outdoor dining in the existing 1,007 square-foot outdoor seating

CASE/FILE NUMBER: Diamond Bar 2021-2029 Housing Element
Update (Planning Case No. PL2021-004)
PROJECT LOCATION:
Citywide
APPLICANT/LEAD AGENCY:
City of Diamond Bar Community Development
Department
RECOMMENDED ACTIONS:
1. Receive staff report
2. Receive public comments
3. Adopt Resolution recommending City Council adoption of the 2021-2029
Housing Element update.
SUMMARY:
On January 26, 2021, the Planning Commission and City Council conducted a joint
workshop to initiate the process of updating the Housing Element of the Diamond Bar
General Plan for the 2021-2029 planning period as required by State law. Additional
public meetings were held by the Planning Commis sion on March 23rd and by the City
Council on April 6th of this year. Staff reports and materials for those previous meetings
are available on the City’s Housing Element web page at:
https://www.diamondbarca.gov/963/Housing-Element-Update.
A draft Housing Element was reviewed by the Planning Commission, City Council and
interested stakeholders, and was submitted to the California Department of Housing
and Community Development (“HCD”) for review as required by State law.
On June 3, 2021, HCD issued a review letter (Attachment 2) finding that the draft
element addressed many statutory requirements; however, revisions will be necessary
to comply with State Housing Element Law.

Page 2 of 8
To address HCD’s comments, City staff has prepared a revised draft Housing Element
(Attachment 3) for review by the Planning Commission and community stakeholders.
Staff recommends that the Commission consider HCD’s comments, staff’s proposed
revisions to the draft Housing Element, and stakeholder comments, and adopt a
Resolution (Attachment 1) recommending that the City Council adopt the revised draft
Housing Element.
After this Planning Commission hearing, staff will prepare a final draft Housing Element
for review by the City Council at a public hearing. Following City Council adoption, the
Housing Element must be submitted to HCD for a second review.
As described below, the draft Housing Element includes several programs calling for
amendments to the Development Code or other land use regulations. Those
amendments will be subject to a subsequent review process including public hearings
held by the Planning Commission and City Council. Adoption of the Housing Element
would not change any current City regulations.
ANALYSIS:
Housing Element Content
The Housing Element focuses on establishing City policies and programs to address the
housing needs of current and future Diamond Bar residents. The Draft Housing Element
includes the following sections:
• An introductory overview of the Housing Element (Section 9.1)
• Needs Assessment including an analysis of the City's demographic and housing
characteristics and trends (Section 9.2)
• Resources and opportunities to address housing needs (Section 9.3)
• Potential governmental and non-governmental constraints to meeting the City's
housing needs (Section 9.4)
• Housing Action Plan describing policies and programs for the 2021-2029
planning period (Section 9.5)
• Review of the City’s accomplishments during the previous planning period
(Appendix A)
• An inventory of sites that could accommodate the City’s new housing needs
(Appendix B); and
• A description of opportunities for stakeholders to participate in the preparation of
the Housing Element (Appendix C)
Key Issues

Diamond Bar 2021-2029 Housing Element Update (Planning Case No. PL2021-004)
Page 3 of 8
Generally, the most significant issues to be addressed in the Housing Element are: 1)
whether City plans and regulations accommodate housing for persons with special
needs in compliance with State law; and 2) how the City will accommodate its share of
regional housing needs assigned through the Regional Housing Needs Assessment
(“RHNA”) process.
Housing for Persons with Special Needs. State law establishes specific requirements
related to City regulation of housing for persons with special needs, including the
homeless and persons with disabilities. Section 9.4 of the Housing Element
(Governmental Constraints) contains an analysis of City plans and regulations for a
variety of housing types. The analysis concluded that while current City regulations are
consistent with most laws regarding special needs housing, some recently adopted laws
will require that the Municipal Code be amended in order to ensure consistency with
State law. Section 9.5 of the Housing Element includes the following programs to
ensure compliance with recent changes to State law:
• Program H-11. Emergency Shelters, Low Barrier Navigation Centers and
Transitional/Supportive Housing. The Development Code establishes standards
and procedures for these types of housing targeted for persons who are homeles s
or at risk of becoming homeless. This program includes a commitment to process a
Development Code amendment in conformance with recent changes to State law.
These changes include allowing supportive housing meeting specified criteria in
zones where multi-family and mixed uses are permitted, and allowing low barrier
navigation centers meeting specified standards in areas zoned for mixed use and in
non-residential zones permitting multi-family uses. Low barrier navigation centers
are defined as “Housing first, low-barrier, service-enriched shelters focused on
moving people into permanent housing that provides temporary living facilities while
case managers connect individuals experiencing homelessness to income, public
benefits, health services, shelter, and housing.”
• Program H-12. Affordable Housing Incentives/Density Bonus. Density bonus refers
to the State law requiring cities to allow increased density and other incentives for
housing developments that include long-term commitments to provide units
affordable to low- and moderate-income households. Recent changes to State
Density Bonus Law have increased the amount of density bonus and other
incentives for affordable housing. This program includes a commitment to amend
the City’s density bonus regulations consistent with current State law.
Regional Housing Needs Assessment. The Regional Housing Needs Assessment
(“RHNA”) is the process established in State law by which future housing needs are
determined for each city. On March 4, 2021 SCAG adopted the fina l RHNA plan, which
assigns Diamond Bar the following housing needs.

The RHNA allocation identifies the amount of additional housing a jurisdiction would
need in order to have enough housing at all price levels to fully accommodate its
assigned share of the region’s housing need during the 8 -year planning period. The
RHNA is a planning requirement based upon housing need, not a construction quota,
mandate or prediction of future housing development . Jurisdictions are not required to
build housing or issue permits to achieve their RHNA allocations, but some provisions of
State law establish specific requirements when housing production falls short of RHNA
allocations. One such requirement is streamlined review and approval of housing
development applications that meet specific standards.1 Other than requirements for
streamlined permit processing, there are currently no legal or financial penalties
imposed on cities for failing to achieve their RHNA allocations so long as a Housing
Element has been adopted in compliance with State law.
The Housing Element is required to provide an evaluation of potential capacity for
additional housing based on land use patterns, development regulations, other
development constraints (such as infrastructure availability and environmental
conditions) and real estate market trends. The analysis must be prepared at a parcel -
specific level of detail and identify properties (or “sites”) where additional housing could
be built consistent with City regulations. This evaluation is referred to as the “sites
analysis” and State law requires the analysis to demonstrate that the City has adequate
sites with appropriate zoning to fully accommodate additional housing development
commensurate with its RHNA allocation in each income category. If the sites analysis
does not demonstrate that adequate capacity exists to fully accommodate the RHNA,
the Housing Element must describe what steps will be taken to increase capacity
commensurate with the RHNA – typically through amendments to land use and zoning
regulations that could facilitate additional housing development. Appendix B of the
Housing Element includes a detailed analysis of sites that could accommodate the
City’s RHNA allocation.
Diamond Bar’s 2040 General Plan, adopted in 2019, estimates that up to 3,750 new
housing units could be built in the City by 2040, depending on market conditions. I t is
expected that much of this growth will occur within the Town Center Mixed Use,
Neighborhood Mixed Use, Transit Oriented Development and Community Core Overlay
focus areas, while most existing residential neighborhoods will experience less growth
and change.
The 2040 General Plan provides the guiding framework for development in these Focus
Areas; however, zoning regulations have not yet been amended to reflect General Plan
policy for these areas. The City will be updating the Development Code to revi se land
use regulations for these Focus Areas consistent with the standards established in the
new General Plan. Program H-8 in Section 9.5 of the Housing Element describes

actions the City intends to take to complete the required zoning amendments in
compliance with State law.
In its review of the draft Housing Element HCD noted that other programs should be
strengthened to reduce constraints to better facilitate housing production consistent with
the RHNA. The revised draft Housing Element includes modi fications to the following
programs in response to HCD comments:
• Program H-7 – Senior and Workforce Housing Development. This program has
been revised to include priority application processing and fee waivers or
deferrals as incentives that may be provided to encourage senior and workforce
housing.
• Program H-8 – Land Use Element and Development Regulations. This program
has been revised to include a commitment to update the Development Code to
include residential and mixed-use parking requirements in conformance with
General Plan policies, streamline the review process, including SB 35 review
procedures, and adopt objective development standards.
• Program H-9 – Mixed Use Development. This program has been revised to
include publishing a handout with marketing materials within 6 months of
Housing Element adoption and continuously thereafter.
• Program H-10 – Accessory Dwelling Units. This program has been revised to
include publishing an ADU handout with marketing materials within 6 months of
Housing Element adoption and continuously thereafter.
• Program H-13 – Efficient Permit Processing. This program has been revised to
include posting of zoning regulations, development standards and fees on the
City website.
ENVIRONMENTAL REVIEW:
On December 17, 2019 the Diamond Bar City Council certified Final EIR No.
SCH 2018051066 for the Diamond Bar 2040 General Plan. The City is now required to
adopt an updated Housing Element for the 2021 -2029 planning period. CEQA
Guidelines Section 15164(a) states: “The lead agency or responsible agency shall
prepare an addendum to a previously certified EIR if some changes or additions are
necessary but none of the conditions described in Section 15162 calling for preparation
of a subsequent EIR have occurred.”
Pursuant to CEQA Guidelines Section 15164 the City has prepared an Addendum to
the General Plan EIR (Attachment 4). The EIR Addendum demonstrates that the 2021 -
2029 Housing Element update would not result in any significant environmental impacts
that were not previously evaluated in the General Plan EIR; therefore, no subsequent
environmental document is required.
PUBLIC REVIEW:

Public participation is a required component of the Housing Element update
process, and residents and other interested stakeholders were provided
numerous opportunities to offer comments and recommendations. Early in the
update process a Housing Element web page was created on the City website
(www.diamondbarca.gov/963/Housing-Element-Update) and a Housing Element
Frequently Asked Questions was prepared and posted on the City’s website. Public
notice, agendas and materials of for all Housing Element meetings were posted on
the website and at City Hall in advance of each meeting a nd also sent by direct mail
to housing advocates and non-profit organizations representing the interests of
lower-income persons and special needs groups. Notices of public hearings were
also published in the local newspaper. Housing Element Appendix C provides
additional information regarding the public review process. Written comments submitted
during the update process are provided as Attachments 6 through 9.

NOTICE OF PUBLIC HEARING:
Notice for this hearing was published in the San Gabriel Valley Tribune newspaper on
October 1, 2021, in a 1/8-page display. Pursuant to Planning and Zoning Law
Government Code Section 65091(a)(4), if the number of property owners to whom a
public hearing notice would be mailed is greater than 1,000, a local agency m ay provide
notice by placing a display advertisement of at least 1/8 page in one newspaper of
general circulation. A copy of the public notice was also posted at the City’s designated
community posting sites.
NEXT STEPS:
Cities are required to submit draft Housing Elements to HCD for review, and must also
address HCD comments prior to City Council adoption of the Housing Element. Exhibit
A of the draft Planning Commission Resolution includes a summary of HCD’s
comments and how the City has addressed those comments. The revised draft Housing
Element shows changes that have been incorporated into the Housing Element to
address HCD’s comments.
Following City Council adoption, the Housing Element must be submitted to HCD for a
second review. The programs described in Housing Element Section 9.5 will be
implemented over the next 8 years according to the timeframe described in each
program. The most significant program actions, such as revisions to the Development
Code and/or preparation of specific plans for General Plan focus areas, must be
completed within three years after Housing Element adoption. Code amendments
needed to reconcile City regulations with recent changes to State law must be
completed within one year. Those future amendments to City regulati ons will include a
separate public review process, including CEQA analysis and public hearings by the
Planning Commission and City Council.

Dear Greg Gubman:
RE: Review of Diamond Bar’s 6th Cycle (2021-2029) Draft Housing Element
Thank you for submitting the City of Diamond Bar’s (City) draft housing element
received for review on April 8, 2021, along with revisions received on May 17, 2021.
Pursuant to Government Code section 65585, subdivision (b), the California
Department of Housing and Community Development (HCD) is reporting the results of
its review. Our review was facilitated by a telephone conversation on May 10, 2021 with
your consultant John Douglas.
The draft element addresses many statutory requirements; however, revisions will be
necessary to comply with State Housing Element Law (Article 10.6 of the Gov. Code). In
particular, to comply with State Housing Element Law the element must provide a
complete sites inventory, including full analyses of the nonvacant sites, as well as
provide a full analysis addressing the required components for Affirmatively Furthering
Fair Housing, among other items. The enclosed Appendix describes these requirements
and other revisions needed to comply with State Housing Element Law.
To remain on an eight-year planning cycle, the City must adopt its housing element
within 120 calendar days from the statutory due date of October 15, 2021 for Southern
California Association of Government localities. If adopted after this date, Government
Code section 65588, subdivision (e)(4) requires the housing element be revised every
four years until adopting at least two consecutive revisions by the statutory deadline.
For more information on housing element adoption requirements, please visit HCD’s
website at: http://www.hcd.ca.gov/community-development/housing-element/housing-
element-memos/docs/sb375_final100413.pdf
Public participation in the development, adoption and implementation of the housing
element is essential to effective housing planning. Throughout the housing element
process, the City should continue to engage the community, including organizations that
7.2.b
Packet Pg. 52
Greg Gubman, Community Development Director
Page 2
represent lower-income and special needs households, by making information regularly
available and considering and incorporating comments where appropriate.
Several federal, state, and regional funding programs consider housing element
compliance as an eligibility or ranking criteria. For example, the CalTrans Senate Bill
(SB) 1 Sustainable Communities grant; the Strategic Growth Council and HCD’s
Affordable Housing and Sustainable Communities programs; and HCD’s Permanent
Local Housing Allocation consider housing element compliance and/or annual reporting
requirements pursuant to Government Code section 65400. With a compliant housing
element, the City meets housing element requirements for these and other funding
sources.
We are committed to assisting the City in addressing all statutory requirements of State
Housing Element Law. If you have any questions or need additional technical
assistance, please contact John Buettner, of our staff, at (916) 841-4756.

HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 1
June 7, 2021
APPENDIX
CITY OF DIAMOND BAR
The following changes are necessary to bring the City’s housing element into compliance
with Article 10.6 of the Government Code. Accompanying each recommended change, we
cite the supporting section of the Government Code.
Housing element technical assistance information is available on HCD’s website at
http://www.hcd.ca.gov/community-development/housing-element/housing-element-
memos.shtml. Among other resources, the housing element section contains HCD’s latest
technical assistance tool, Building Blocks for Effective Housing Elements (Building Blocks),
available at http://www.hcd.ca.gov/community-development/building-blocks/index.shtml and
includes the Government Code addressing State Housing Element Law and other
resources.
A. Review and Revision
Review the previous element to evaluate the appropriateness, effectiveness, and
progress in implementation, and reflect the results of this review in the revised element.
(Gov. Code, § 65588 (a) and (b).)
The element does not fully review the previous element and evaluate the appropriateness
and effectiveness in implementation. Specifically, the element must be revised to analyze
the effectiveness of prior programs. For example, Housing Program 14 states that the City
was to encourage production of housing through the provisions of incentives but does not
state if incentives were developed, offered, or provided to developers. The element must
provide a more detailed narrative describing the actual results or outcomes of the prior
housing element’s goals, objectives, policies, and programs.
In addition, the element must evaluate the appropriateness of the goals, objectives,
policies, and programs. For example, while the element states if program is to be
continued in the 6th cycle housing element, it does not indicate if modifications are
necessary to achieve better results in the new housing element cycle. The element
must provide narrative describing what has been learned based on the analysis or
effectiveness of the previous element, as described above.
B. Housing Needs, Resources, and Constraints
1. Affirmatively further[ing] fair housing in accordance with Chapter 15 (commencing with
Section 8899.50) of Division 1 of Title 2…shall include an assessment of fair housing in
the jurisdiction (Gov. Code, § 65583, subd. (c)(10)(A))
Program H-14 speaks to fair housing policies, entitlement reviews and fairness in
approving development applications, accommodations for persons with disabilities,
public outreach, and stakeholder engagement. This is not sufficient to cover the
AFFH area. In addition to the provisions in H-14, the assessment of fair housing
must include an analysis related to racially and ethnically concentrated areas of
poverty, disparities in access to opportunities and disproportionate housing needs,
including displacement risks. Further, the element contains no analysis to
7.2.b
Packet Pg. 54
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 2
June 7, 2021
adequately identify and prioritize contributing factors to fair housing issues and
formulate meaningful and significant goals and actions. An analysis generally will
identify all the above fair housing areas, evaluate patterns and trends, analyze other
relevant factors, and summarize findings to better inform and prioritize contributing
factors to fair housing issues and formulate goals and actions. Specifically, the
element must include:
• Identification and analysis of integration and segregation on protected
characteristics, including race, disability, familial status, and income.
Identification and analysis must also fully address disproportionate housing
needs, including overpayment, overcrowding and substandard housing and
access to opportunities for persons with disabilities.
• For all analysis categories (e.g., fair housing enforcement, segregation, and
integration, racially and ethnically concentrated areas of poverty, disparities in
access to opportunities and disproportionate housing needs), discuss patterns
and trends relative to the region.
• For all analysis categories, analyze other relevant factors, including demographic
trends relative to the region, and any other relevant policy or program areas. The
City must also consider relativity to the region as well as other relevant factors
and address a summary of fair housing issues based on the outcomes of a
complete analysis.
• The element must analyze whether sites are located throughout the community
to affirmatively further fair housing. For example, the element should analyze
identified sites relative to access to opportunity segregation and integration,
racially and ethnically concentrated areas of poverty and affluence and
displacement risk. The element should also discuss whether the identified sites
serve the purpose of replacing segregated living patterns with truly integrated
and balanced living patterns, transforming racially and ethnically concentrated
areas of poverty into areas of opportunity.
• The element must list and prioritize contributing factors to fair housing issues.
Contributing factors create, contribute to, perpetuate, or increase the severity
of fair housing issues and are fundamental to adequate goals and actions.
Examples include community opposition to affordable housing, housing
discrimination, land use and zoning laws, lack of regional cooperation, location
and type or lack of affordable housing and lack of public or private investment in
areas of opportunity or affordable housing choices.
• Goals and actions must significantly seek to overcome contributing factors to
fair housing issues. These actions are not limited to the regional housing need.
For example, the element may need to consider zoning or land use changes
regardless of the regional housing need allocation (RHNA). The element must
add, and revise programs based on a complete analysis and listing and
prioritization of contributing factors to fair housing issues.

HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 3
June 7, 2021
For further information about AFFH requirements, please refer to HCD’s
Affirmatively Further Fair Housing guidance memo.
2. Include an analysis of population and employment trends and documentation of
projections and a quantification of the locality's existing and projected needs for all
income levels, including extremely low-income households. (Gov. Code, § 65583,
subd. (a)(1).)
Population and employment trends are important to understanding the diversity of
the City’s residents and economic growth patterns in the City. This data is integral in
determine housing needs at various levels and aids in determining actions and
programs the City can implement to address various issues. Additionally, race and
ethnicity are important in addressing the City’s AFFH obligations. The draft element
provides data on the City’s population trends but should also provide data or
analysis on race and ethnicity.
3. Include an analysis and documentation of household characteristics, including level
of payment compared to ability to pay, housing characteristics, including
overcrowding, and housing stock condition. (Gov. Code, § 65583, subd. (a)(2).)
The draft element includes data on household characteristics, level of payments
compared to ability to pay, overcrowding, and general housing stock condition.
However, data for extremely low-income (ELI) households does not consider tenure
as seen in Table 9-4, nor does the analysis provide information on potential housing
problems and specific housing needs of this economic group. These analyses are
vital to determining the needs of all households, including ELI, so that the City can
address any deficiencies and implement actions and programs that address their
needs.
4. An inventory of land suitable and available for residential development, including
vacant sites and sites having realistic and demonstrated potential for redevelopment
during the planning period to meet the locality’s housing need for a designated
income level, and an analysis of the relationship of zoning and public facilities and
services to these sites. (Gov. Code, § 65583, subd. (a)(3).)
The City has a (RHNA) of 2,521 housing units, of which 1,281 are for lower-income
households. To address this need, the element relies on nonvacant and
underutilized sites in the newly designated Town Center, Neighborhood Mixed-use,
and Transit-Oriented Mixed-Use Focus Areas. All sites listed for all income ranges in
the sites inventory need rezoning consistent with the newly revised general plan.
Additionally, over fifty percent of the sites are being used to accommodate the City’s
lower-income RHNA, which requires additional analysis. To demonstrate the
adequacy of these sites and strategies to accommodate the City’s RHNA, the
element must include complete analyses of the following:
Sites Inventory: While the sites inventory lists the address, APN, existing zoning,
parcel size, allowable density, whether or not the sites are publicly owned, income
categories, and estimated total units, it must also identify the site’s general plan
designations and provide a more detailed description of the existing uses of the
7.2.b
Packet Pg. 56
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 4
June 7, 2021
nonvacant sites beyond a general description of “commercial”. For additional
information, see the Building Blocks at http://www.hcd.ca.gov/community-
development/building-blocks/site-inventory-analysis/inventory-of-land-suitable.shtml.
Please note, Pursuant to SB 6 (Chapter 667, Statutes of 2019), for a housing
element or amendment adopted on or after January 1, 2021, the planning agency
shall submit to HCD an electronic copy of its inventory of these parcels using
standards, forms, and definitions adopted by HCD. For further information, refer to
HCD’s Housing Element Site Inventory Guidebook.
Map of Sites: While the element has general land use map (figure B-1), the map must
identify the location of the sites within the sites inventory.
Realistic Capacity: The element does not fully analyze the City’s methodology for
calculating realistic capacity for sites listed in the sites inventory. For sites zoned for
nonresidential uses, e.g. commercial and mixed-use zones, the element must
describe how the estimated number of residential units for each site was
determined. To demonstrate the likelihood for residential development in
nonresidential zones, the element could describe any performance standards
mandating a specified portion of residential and any factors increasing the potential
for residential development such as incentives for residential use, and residential
development trends in the same nonresidential zoning districts. For additional
information, see the Building Blocks at http://www.hcd.ca.gov/community-
development/building-blocks/site-inventory-analysis/analysis-of-sites-and-
zoning.shtml#analysis.
Suitability of Nonvacant Sites: Appendix B, Methodology for the Sites Inventory
Analysis, offers high-level analysis of the Town Center, Neighborhood Mixed Use,
and Transit-oriented Mixed-Use focus areas. However, the element must include an
analysis to demonstrate the potential for redevelopment. The analysis shall consider
factors including, but not limited to, the extent existing uses constitute an
impediment, recent developments, development trends and market conditions. In
addition, as the element appears to rely on nonvacant sites to accommodate 50
percent or more of the housing needs for lower-income households, this triggers
requirements to make findings based on substantial evidence that the existing use is
not an impediment and will likely discontinue in the planning period. For additional
information and sample analysis, see the Building Blocks at
http://www.hcd.ca.gov/community-development/building-blocks/site-inventory-
analysis/analysis-of-sites-and-zoning.shtml#analysis.
Second Units: The element incorrectly calculates accessory dwelling unit (ADU)
potential for the planning period by considering a rate of 8 ADUs per year based on
the most recent (2020) production. Specifically, in addition to other methods, HCD
accepts the use of trends in ADU construction since January 2018 to estimate new
production. Based on past production between 2018 to 2020, the City is averaging
5 units per year. The City can increase this estimate if it includes addition analysis
that includes information such as how community needs and demand are likely to
increase production and include programs that aggressively promote and incentivize
ADU construction.

June 7, 2021
Infrastructure: While the element describes water and sewer infrastructure, it must
also demonstrate sufficient existing or planned dry utilities supply capacity, including
the availability and access to distribution facilities to accommodate the City’s
regional housing need for the planning period (Gov. Code, § 65583.2, subd. (b).).
For additional information, see the Building Blocks at
http://www.hcd.ca.gov/community-development/building-blocks/site-inventory-
analysis/analysis-of-sites-and-zoning.shtml#environmental.
Water Sewer Priority: The element does not address water and sewer priority. For
your information, water and sewer service providers must establish specific
procedures to grant priority water and sewer service to developments with units
affordable to lower-income households. (Gov. Code, § 65589.7.) Local governments
are required to immediately deliver the housing element to water and sewer service
providers. HCD recommends including a cover memo describing the City’s housing
element, including the City’s housing needs and regional housing need. For
additional information and sample cover memo, see the Building Blocks at
http://www.hcd.ca.gov/community-development/building-blocks/other-
requirements/priority-for-water-sewer.shtml.
5. An analysis of potential and actual governmental constraints upon the maintenance,
improvement, or development of housing for all income levels, including the types of
housing identified in paragraph (1) of subdivision (c), and for persons with disabilities
as identified in the analysis pursuant to paragraph (7), including land use controls,
building codes and their enforcement, site improvements, fees and other exactions
required of developers, and local processing and permit procedures. The analysis
shall also demonstrate local efforts to remove governmental constraints that hinder
the locality from meeting its share of the regional housing need in accordance with
Government Code section 65584 and from meeting the need for housing for persons
with disabilities, supportive housing, transitional housing, and emergency shelters
identified pursuant to paragraph (7). Transitional housing and supportive housing
shall be considered a residential use of property and shall be subject only to those
restrictions that apply to other residential dwellings of the same type in the same
zone (Gov. Code, § 65583, subd. (a)(5)).
Land Use Controls: While the element lists parking requirements at 2 spaces per
unit for multifamily uses, it must also analyze the requirements as a potential
constraint on the cost and supply of housing and ability to achieve maximum
densities.
The City must address whether it has complied with new transparency laws requiring
all zoning and development standards for each parcel to be provided on the
jurisdiction’s website (Gov. Code 65940.1 (a)(1)(B)).
Fees and Exactions: The element must describe all required fees for single family
and multifamily housing development, including impact fees, and analyze their
impact as potential constraints on housing supply and affordability. For example, the
analysis could identify the total amount of fees and their proportion to the
development costs for both single family and multifamily housing. The element lists
7.2.b
Packet Pg. 58
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 6
June 7, 2021
the basic fees and exactions for development projects across the board. However, it
should also demonstrate typical costs for Multifamily and Single-Family Residence
construction. Additionally, the element should also address whether the City has
complied with the new transparency laws requiring fees and inclusionary
requirements to be provided on a jurisdiction’s website (GC 65940.1(a)(1)(A)). For
additional information and a sample analysis and tables, see the Building Blocks at
http://www.hcd.ca.gov/community-development/building-blocks/constraints/fees-and-
exactions.shtml.
Local Processing and Permit Procedures: The element provides a general overview
of the City’s processing and permit procedures. However, the element should
provide average processing times for single-family and multifamily developments.
The element also acknowledges that single-family residences and multifamily
developments are permitted by-right in their respective zones but require
“Development Review” (page 9-41). In addition, according to the City’s website,
Diamond Bar has adopted design guidelines. The element must describe and
analyze the development application process and design review requirements
including approval procedures and decision-making criteria for their impact as
potential constraints on housing supply and affordability. For example, the analysis
could describe required findings and discuss whether objective standards and
guidelines improve development certainty and mitigate cost impacts. The element
must demonstrate this process is not a constraint and include a program to address
this permitting requirement, as appropriate.
Persons with Disabilities: While the element briefly describes its reasonable
accommodation procedures, it should further explain its reasonable accommodation
criteria and process. In addition, the element must analyze its conditional use permit
process for residential care facilities for seven or more persons as a potential barrier
to housing for persons with disabilities and include programs as necessary to
address this constraint. For additional information and sample analysis, see the
Building Blocks at http://www.hcd.ca.gov/community-development/building-
blocks/constraints/constraints-for-people-with-disabilities.shtml.
Codes and Code Enforcement: While the element states that the City building codes
are based upon the California Building, Plumbing, Mechanical and Electrical Codes,
it must also describe its code enforcement processes and procedures. For additional
information and a sample analysis, see the Building Blocks at
https://www.hcd.ca.gov/community-development/building-blocks/constraints/codes-
and-enforcement-on-offsite-improvement-standards.shtml.
6. An analysis of potential and actual nongovernmental constraints upon the
maintenance, improvement, or development of housing for all income levels,
including the availability of financing, the price of land, the cost of construction, the
requests to develop housing at densities below those anticipated in the analysis
required by subdivision (c) of Government Code section 65583.2, and the length of
time between receiving approval for a housing development and submittal of an
application for building permits for that housing development that hinder the
construction of a locality’s share of the regional housing need in accordance with
Government Code section 65584. The analysis shall also demonstrate local efforts
7.2.b
Packet Pg. 59
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 7
June 7, 2021
to remove nongovernmental constraints that create a gap between the locality’s
planning for the development of housing for all income levels and the construction of
that housing. (Gov. Code, § 65583, subd. (a)(6)).
Price of land, Cost of Construction, and Availability of Financing: While, the element
includes a high-level analysis of availability of financing, the price of land, the cost of
construction, it should be revised to analyze quantifiable cost data and its impact on
the supply of housing.
Requests for Lower Density, Permit Times, and Efforts to Address Non-
Governmental Constraints: The element must include analysis regarding local efforts
to address non-governmental constraints that create a gap in the jurisdiction’s ability
to meet RHNA by income category, an identification and analysis of requests to
develop at densities below the density identified in the site inventory, and a
description of the length of time between project approval and request for building
permit that hinders the jurisdiction’s ability to accommodate RHNA by income
category. For example, the City can look at recent developments in the jurisdiction
and identify any non-governmental constraints.
7. Analyze any special housing needs such as elderly; persons with disabilities,
including a developmental disability; large families; farmworkers; families with female
heads of households; and families and persons in need of emergency shelter. (Gov.
Code, § 65583, subd. (a)(7).)
Elderly: While the element provides some data on elderly households by income and
tenure and list programs amenable to this category of special needs, it should also
include an analysis of potential housing problems and unmet needs to better target
programs to address housing needs.
Persons with Disabilities including Developmental Disabilities: While the element
provides some data for persons with disabilities by type and age and list programs, it
should also include an analysis of potential housing problems and unmet needs to
better target programs to address housing needs.
C. Housing Programs
1. Include a program which sets forth a schedule of actions during the planning period,
each with a timeline for implementation, which may recognize that certain programs
are ongoing, such that there will be beneficial impacts of the programs within the
planning period, that the local government is undertaking or intends to undertake to
implement the policies and achieve the goals and objectives of the housing element
through the administration of land use and development controls, the provision of
regulatory concessions and incentives, and the utilization of appropriate federal and
state financing and subsidy programs when available. The program shall include an
identification of the agencies and officials responsible for the implementation of the
various actions. (Gov. Code, § 65583, subd. (c).)
To address the program requirements of Gov. Code section 65583, subd. (c)(1-6),
and to facilitate implementation, all programs should be revised to include: (1) a
7.2.b
Packet Pg. 60
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 8
June 7, 2021
description of the City’s specific role in implementation; (2) definitive implementation
timelines (e.g., December 31, 2021); (3) objectives, quantified where appropriate;
and (4) identification of responsible agencies and officials (e.g., Planning Assistant,
Community Development, etc.). In addition, the following programs required
additional revisions.
Program H-1, Residential Neighborhood Improvement Program: Program H-1
quantifies how many eligible homes the City is targeting to assist, which is 5-6, but
should be revised to clarify if that will be over the 8-year period or annually.
Program H-2, Home Improvement Program: Program H-2 speaks to the use of
CDBG funds the City uses for the program but does not address the City’s specific
role in administration or identify responsible agencies and officials.
Program H-3, Section 8 Rental Assistance Program: Programs should describe the
City’s specific role in implementation and identify responsible agencies and officials.
Program H-3 states that the Home improvement program utilizes CDBG funds, but it
does not address the City’s specific role in implementation.
2. Identify actions that will be taken to make sites available during the planning period
with appropriate zoning and development standards and with services and facilities
to accommodate that portion of the city’s or county’s share of the regional housing
need for each income level that could not be accommodated on sites identified in the
inventory completed pursuant to paragraph (3) of subdivision (a) without rezoning,
and to comply with the requirements of Government Code section 65584.09. Sites
shall be identified as needed to facilitate and encourage the development of a
variety of types of housing for all income levels, including multifamily rental housing,
factory-built housing, mobilehomes, housing for agricultural employees, supportive
housing, single-room occupancy units, emergency shelters, and transitional housing
(Gov. Code, § 65583, subd. (c)(1)).
As noted in the Finding B4, the element does not include a complete sites inventory
or analysis; as a result, the adequacy of sites and zoning has not been established.
Based on the results of a complete sites inventory and analysis, programs may need
to be added, or revised, to address a shortfall of sites and zoning for a variety of
housing types.
The element identifies sites in the Town Center, Neighborhood Mixed Use, and
Transit-Oriented Mixed-Use Focus Areas which, while identified in the 2019 General
plan, still require zoning and development code updates to be available to for
housing development. This represents a shortfall of sites to accommodate the City’s
share of the regional housing need. While the element includes Program H-8 to
complete the amendments to the development code within three years of housing
element adoption, the program must be amended to demonstrate a commitment to
accommodate 100 percent of the shortfall of sites necessary to accommodate the
remaining housing need for housing for very low- and low-income households during
the planning period and include the following components:
7.2.b
Packet Pg. 61
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 9
June 7, 2021
• Permit owner-occupied and rental multifamily uses by right for developments
in which 20 percent or more of the units are affordable to lower income
households. By right means local government review must not require a
conditional use permit, planned unit development permit, or other
discretionary review or approval.
• Permit the development of at least 16 units per site.
• Require a minimum density of 20 units per acre; and
• Ensure a) at least 50 percent of the shortfall of low- and very low-income
regional housing need can be accommodated on sites designated for
exclusively residential uses, or b) if accommodating more than 50 percent of
the low- and very low-income regional housing need on sites designated for
mixed-uses, all sites designated for mixed-uses must allow 100 percent
residential use and require residential use to occupy at least 50 percent of the
floor area in a mixed-use project.
3. The housing element shall contain programs which assist in the development of
adequate housing to meet the needs of extremely low-, very low-, low- and
moderate-income households. (Gov. Code, § 65583, subd. (c)(2).)
Program H-7, Senior and Workforce Housing Development, encourages the
development of senior and workforce housing, including very-low (VL) and extremely
low-income (ELI) persons. However, this program alone is insufficient in
encouraging and facilitating the development of housing for ELI and VL income
categories. The element must include a program(s) with specific actions and
timelines to assist in the development of housing for extremely low-, very low-, low-,
and moderate-income households. The program(s) could commit the City to
adopting priority processing, granting fee waivers or deferrals, modifying
development standards, granting concessions and incentives for housing
developments that include units affordable to lower and moderate-income
households; assisting, supporting or pursuing funding applications; and working with
housing developers coordinate and implement a strategy for developing housing
affordable to lower and moderate-income households. For additional information,
see the Building Blocks at http://www.hcd.ca.gov/community-development/building-
blocks/program-requirements/assist-in-development-housing.shtml and for financial
assistance programs, see HCD’s website at
http://www.hcd.ca.gov/fa/LG_program_directory.pdf.
4. Address and, where appropriate and legally possible, remove governmental and
nongovernmental constraints to the maintenance, improvement, and development of
housing, including housing for all income levels and housing for persons with
disabilities. The program shall remove constraints to, and provide reasonable
accommodations for housing designed for, intended for occupancy by, or with
supportive services for, persons with disabilities. (Gov. Code, § 65583, subd. (c)(3).)
As noted in Finding(s) B5 and B6, the element requires a complete analysis of
potential governmental and non-governmental constraints. Depending upon the
results of that analysis, the City may need to revise or add programs and address
and remove or mitigate any identified constraints.
7.2.b
Packet Pg. 62
HCD’s Review of Diamond Bar’s 6th Cycle Housing Element Draft Page 10
June 7, 2021
5. Promote and affirmatively further fair housing opportunities and promote housing
throughout the community or communities for all persons regardless of race,
religion, sex, marital status, ancestry, national origin, color, familial status, or
disability, and other characteristics protected by the California Fair Employment and
Housing Act (Part 2.8 (commencing with Section 12900) of Division 3 of Title 2),
Section 65008, and any other state and federal fair housing and planning law. (Gov.
Code, § 65583, subd. (c)(5).)
As noted in Finding B1, the element must include a complete analysis of
affirmatively furthering fair housing. Based on the outcome of that analysis, the
element must add or modify programs. Additionally, programs and actions need to
be significant, meaningful, and sufficient to overcome identified patterns of
segregation and affirmatively further fair housing.
D. Public Participation
Local governments shall make a diligent effort to achieve public participation of all
economic segments of the community in the development of the housing element, and
the element shall describe this effort. (Gov. Code, § 65583, subd. (c)(8).)
While the element includes a general summary of the public participation process (page
9-80, Appendix C), it must also demonstrate diligent efforts were made to involve all
economic segments of the community in the development of the housing element. For
example, according to the American Communities Data, the City is made up of multiple
ethnic groups. The element could describe how these groups were reached and if
materials and meetings were offered in multiple languages.
For your information, some general plan element updates are triggered by housing
element adoption. For example, a jurisdiction must address environmental justice in its
general plan by the adoption of an environmental justice element, or by the integration
of environmental justice goals, policies, and objectives into other general plan elements
upon the adoption or next revision of two or more elements concurrently on or after
January 1, 2018. (Gov. Code, § 65302, subd. (h).) In addition, the safety and
conservation elements of the general plan must include analysis and policies regarding
fire and flood hazard management and be revised upon each housing element revision.
(Gov. Code, § 65302, subd. (g).) Also, the land-use element must identify and analyze
disadvantaged communities (unincorporated island or fringe communities within
spheres of influence areas or isolated long-established legacy communities) on, or
before, the housing element’s adoption due date. (Gov. Code, § 65302.10, subd. (b).)
HCD reminds the City to consider timing provisions and welcomes the opportunity to
provide assistance. For information, please see the Technical Advisories issued by the
Governor’s Office of Planning and Research at:

9.1 INTRODUCTION
COMMUNITY CONTEXT
Diamond Bar is a scenic community
located in the San Gabriel Valley on
the eastern edge of Los Angeles
County, within minutes of Orange,
Riverside, and San Bernardino counties.
With its origin as a center for ranching
perched among a landscape of rolling
hills in the East San Gabriel Valley,
suburban-style growth later established
Diamond Bar as a residential
community known for its friendly
country-living atmosphere, abundant
open spaces, exceptional public
facilities, well-maintained parks and
hiking trails, and excellent schools.
With convenient access to State Route
57 (SR-57) and SR-60, Diamond Bar is
within 30 miles driving distance of the
cities of Los Angeles, Riverside, and
Irvine, making it a desirable part of the
region to live and work. Diamond Bar is
bounded by the cities of Industry and
Pomona to the north and Chino Hills to
the east, and unincorporated Los
Angeles County to the south and west.
The western edge of the city lies at the
intersection of SR-57 and SR-60, with
SR-57 connecting the city to Interstate
10 (I-10) 1½ miles to the north and SR-60
connecting to SR-71 roughly 2 miles to
the east. The Industry Metrolink Station
lies on Diamond Bar’s northern border
with the City of Industry, providing east-
west transit connections to Los Angeles
and Riverside. The regional setting is
depicted in Figure 9-1.
Most of the easily buildable land in the
City has already been developed, and
much of the remaining land has a
variety of geotechnical and topo-
graphic conditions that may constrain
future development. As a result, a
significant portion of future residential
growth in Diamond Bar is expected to
occur through redevelopment of
commercial or light industrial properties,
particularly those designated for mixed-
use development in the
comprehensive 2040 General Plan
update.
R OLE OF HOUSING ELEMENT
Diamond Bar is faced with various
important housing issues that include a
balance between employment and
housing opportunities, a match
between the supply of and demand for
housing, preserving and enhancing
affordability for all segments of the
population, preserving the quality of
the housing stock, and providing new
types of housing necessary to
accommodate growth and the
changing population. This Housing
Element provides policies and
programs to address these issues.
Diamond Bar's Housing Element is an
8-year plan for the period 2021-2029,
unlike other General Plan elements
which typically cover a 10- to 20-year
planning horizon.

The Diamond Bar Housing Element
consists of the following major
components:
• This Introduction to the Housing
Element
• An analysis of the City's
demographic and housing
characteristics and trends
(Section 9.2)
• An evaluation of resources and
opportunities available to address
housing issues (Section 9.3)
• A review of potential market,
governmental, and environmental
constraints to meeting the City’s
identified housing needs
(Section 9.4)
• The Housing Action Plan for the
2021-2029 planning period
(Section 9.5)
• A review of the City’s accomplish-
ments during the previous
planning period (Appendix A)
• A detailed inventory of the
suitable sites for housing
development (Appendix B); and
• A description of opportunities for
stakeholders to participate in the
preparation of the Housing
Element (Appendix C)
PUBLIC PARTICIPATION
Residents, businesses and interest
groups were provided the opportunity
to participate in the Housing Element
update process and were an
important component of the overall
program. Details regarding
opportunities for public involvement
during the preparation and adoption
of this Housing Element are provided in
Appendix C.
RELATIONSHIP T O OTHER GENERAL PLAN ELEMENTS
In addition to the Housing Element, the
City of Diamond Bar General Plan
consists of the following Chapters:
• Land Use & Economic
Development
• Community Character &
Placemaking
• Circulation
• Resource Conservation
• Public Facilities & Services
• Public Safety
• Community Health & Sustainability
This Housing Element builds upon and is
consistent with the other General Plan
chapters. For example, residential land
use designations established in the
Land Use Element and potential
constraints described in the Resource
Conservation and Public Facilities and
Services elements are reflected in the
Housing Element sites inventory
(Appendix B). As the General Plan is
amended from time to time, the
Housing Element will be reviewed for
consistency, and amended as
necessary to maintain an internally
consistent General Plan.

9.2 HOUSING NEEDS ASSESSMENT
This section examines Diamond Bar’s
general population and household
characteristics and trends, such as age,
employment, household composition
and size, household income, and
special needs. Characteristics of the
existing housing stock (e.g., number of
units and type, tenure, age and
condition, costs) are also addressed.
Finally, the City’s projected housing
needs based on the 2021-2029
Regional Housing Needs Assessment
(RHNA) are examined.
The data presented in this section has
been compiled by the Southern
California Association of Governments
(SCAG) based upon recent data from
the U.S. Census, California Department
of Finance (DOF), California
Employment Development Department
(EDD) and other relevant sources and
has been pre-approved by the
California Department of Housing and
Community Development (HCD).
POPULATION CHARACTERISTICS
Population Growth Trends
Diamond Bar was incorporated in 1989
with much of its territory already
developed. From 2000 to 2020 the
City’s population increased from 56,287
to an estimated population of 57,177
(see Table 9-1), an annual growth rate
of 0.1% compared to 0.7% for the SCAG
region as a whole.
Table 9-1: Population Trends, 2000-2020, Diamond Bar vs. SCAG Region
Age
Housing needs are influenced by the
age characteristics of the population.
Different age groups require different
accommodations based on lifestyle,
family type, income level, and housing
preference. Table 9-2 provides a
comparison of the City’s population by
age group. The population of Diamond
Bar is 49.1% male and 50.9% female.

HOUSEHOLD CHARACTERISTICS
Overcrowding
Overcrowding is often closely related to
household income and the cost of
housing. The U.S. Census Bureau
considers a household to be over-
crowded when there is more than one
person per room, excluding bathrooms
and kitchens, and severely overcrowded
when there are more than 1.5
occupants per room. Table 9-3
summarizes the incidence of over-
crowding for Diamond Bar as compared
to the SCAG region as a whole.
Table 9-3: Overcrowding by Tenure, Diamond Bar and SCAG Region
According to recent Census data
overcrowding was more prevalent
among renters than for owner-
occupied units. Approximately 10.9%
of the City’s renter-occupied
households were overcrowded
compared to 2.4% of owner-occupied
households. The incidence of over-
crowding in Diamond Bar was
substantially lower than is typical for
the SCAG region as a whole. Many of
the policies and programs described in
Section 9.5 - Housing Action Plan will
help to address the problem of
overcrowding, particularly Program H-3

Household Income
Household income is a primary factor
affecting housing needs in a
community, particularly for extremely-
low-income households, defined as 30%
of median income or less. According to
recent Census data, approximately
7.9% of households in Diamond Bar
were within the extremely-low-income
(ELI) category, and renters were much
more likely than owners to fall within the
ELI category (Table 9-4).
Table 9-4: Extremely-Low-Income Households, Diamond Bar
Housing Affordability and Overpayment
Housing Affordability Criteria
State law establishes five income
categories for purposes of housing
programs based on the area (i.e.,
county) median income (AMI):
extremely-low (30% or less of AMI), very-
low (31-50% of AMI), low (51-80% of
AMI), moderate (81-120% of AMI) and
above moderate (over 120% of AMI).
Housing affordability is based on the
relationship between household
income and housing expenses.
According to the U.S. Department of
Housing and Urban Development (HUD)
and the California Department of
Housing and Community Development
(HCD), housing is considered
“affordable” if monthly housing cost is
no more than 30% of a household’s
gross income. In some areas such as Los
Angeles County, these income limits
may be increased to adjust for high
housing costs.
Table 9-5 shows affordable rent levels
and estimated affordable purchase
prices for housing in Diamond Bar (and
Los Angeles County) by income
category. Based on State-adopted
standards for a 4-person family, the
maximum affordable monthly rent for
extremely-low-income households is
$845, while the maximum affordable
rent for very-low-income households is
$1,407. The maximum affordable rent
for low-income households is $2,252,
while the maximum for moderate-
income households is $2,319. Maximum
purchase prices are more difficult to
determine due to variations in
mortgage interest rates and qualifying
procedures, down payments, special
tax assessments, homeowner

association fees, property insurance
rates, etc. With this caveat, the
maximum affordable home purchase
price for moderate-income households
has been estimated based on typical
conditions. Affordable prices have not
been estimated for the lower-income
categories because most for-sale
affordable housing is provided at the
moderate-income level.

EMPLOYMENT
Employment is an important factor
affecting housing needs within a
community. The jobs available in each
employment sector and the wages for
these jobs affect the type and size of
housing residents can afford.
According to recent Census data,
Diamond Bar had 27,198 workers living
within its borders who work across 13
major industrial sectors (Table 9-12). The
most prevalent industry is Education &
Social Services with 6,726 employees
(24.7% of total) and the second most
prevalent industry is Professional
Services with 3,894 employees (14.3% of

in Diamond Bar is Management, in
which 14,448 (53.1% of total)

HOUSING STOCK CHARACTERISTICS
This section presents an evaluation of
the characteristics of the community’s
housing stock and helps in identifying
and prioritizing needs. The factors
evaluated include the number and
type of housing units, tenure, vacancy,
housing age and condition. A housing
unit is defined as a house, apartment,
mobile home, or group of rooms,
occupied as separate living quarters, or
if vacant, intended for occupancy as
separate living quarters.
Housing Type and Tenure
Diamond Bar's housing stock contained
a total of approximately 17,645 total
units in 2020, of which about 72% were
single-family detached homes (Table 9-
14). As seen in Table 9-15, over three-
quarters of homes in Diamond Bar were
owner-occupied as compared to only
about 52% in the SCAG region).

Table 9-17 shows recent data for

SCAG region. The largest categories of
vacant units in Diamond Bar were units
for rent and units held for seasonal use.
Table 9-17: Vacant Units by Type, Diamond Bar and SCAG Region
Housing Age and Conditions
Housing age is often an important
indicator of housing condition. Housing
units built prior to 1978 before stringent
limits on the amount of lead in paint
were imposed may have interior or
exterior building components coated
with lead-based paint. Housing units
built before 1970 are the most likely to
need rehabilitation and to have lead-
based paint in a deteriorated
condition. Lead-based paint becomes
hazardous to children under age six
and to pregnant women when it peels
off walls or is pulverized by windows
and doors opening and closing.
Table 9-18 shows the age distribution of
the housing stock in Diamond Bar
compared to the SCAG region as a
whole. This table shows that about half
of housing units in Diamond Bar were
constructed before 1980. These findings
suggest that there may be a need for
maintenance and rehabilitation,
including remediation of lead-based
paint, for a substantial number of
housing units.
Table 9-18: Age of Housing Stock, Diamond Bar and SCAG Region

Packet Pg. 82
9-16 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
The majority of Diamond Bar's housing
stock is in good to excellent condition.
However, some housing units in older
neighborhoods exhibit signs of deferred
maintenance such as peeling paint,
worn roofs, and cracked asphalt
driveways. The Housing Action Plan
(Section 9.5) establishes a program
directed at improving housing stock in
these areas through targeted
rehabilitation assistance. Fewer than
100 units are estimated to need
rehabilitation citywide, and no units
require replacement.
SPECIAL NEEDS
Certain groups have greater difficulty in
finding decent, affordable housing due
to special circumstances. Such
circumstances may be related to one’s
employment and income, family
characteristics, disability, or other
conditions. As a result, some Diamond
Bar residents may experience a higher
prevalence of overpayment, over-
crowding, or other housing problems.
State Housing Element law defines
“special needs” groups to include
persons with disabilities, the elderly,
large households, female-headed
households with children, homeless
people, and farm workers. This section
contains a discussion of the housing
needs facing each of these groups.
Persons with Disabilities
According to recent Census estimates,
the most prevalent types of disabilities
for Diamond Bar residents were
ambulatory, independent living and
cognitive disabilities (see Table 9-19).
Housing opportunities for those with
disabilities can be maximized through
housing assistance programs, providing
universal design features such as
widened doorways, ramps, lowered
countertops, single-level units and
ground floor units, supportive housing,
residential care facilities and assisted
living facilities.

In Diamond Bar, the most commonly
occurring disability among seniors 65
and older was an ambulatory disability,
experienced by 17.4% of Diamond Bar's
seniors and 22.9% of seniors in the
SCAG region (Table 9-20). Section 9.5 -
Housing Action Plan addresses the
needs of persons with disabilities
through Program H-11 (Emergency
Shelters, Low Barrier Navigation Centers
and Transitional/Supportive Housing),
Program H-14 (Affirmatively Furthering
Fair Housing) and Program H-15
(Reasonable Accommodation for
Persons with Disabilities).
Table 9-20: Disabilities by Type for Seniors 65+, Diamond Bar and SCAG Region
Develo pmental Disab ilities
As defined by federal law,
“developmental disability” means a
severe, chronic disability of an
individual that:
• Is attributable to a mental or
physical impairment or
combination of mental and
physical impairments;
• Is manifested before the individual
attains age 22;
• Is likely to continue indefinitely;
• Results in substantial functional
limitations in three or more of the
following areas of major life
activity: a) self-care; b) receptive
and expressive language;
c) learning; d) mobility; e) self-
direction; f) capacity for
independent living; or
g) economic self-sufficiency; and
• Reflects the individual’s need for a
combination and sequence of
special, interdisciplinary, or
generic services, individualized
supports, or other forms of
assistance that are of lifelong or
extended duration and are
individually planned and
coordinated.
The Census does not record develop-
mental disabilities as a separate
category of disability. According to the
U.S. Administration on Developmental
Disabilities, an accepted estimate of
the percentage of the population that
can be defined as developmentally
disabled is 1.5 percent. Many develop-
mentally disabled persons can live and
work independently within a conven-
tional housing environment. More
severely disabled individuals require a
group living environment where
supervision is provided. The most
severely affected individuals may
require an institutional environment
7.2.c
Packet Pg. 84
9-18 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
where medical attention and physical
therapy are provided. Because
developmental disabilities exist before
adulthood, the first issue in supportive
housing for the developmentally
disabled is the transition from the
person’s living situation as a child to an
appropriate level of independence as
an adult.
Table 9-21: Developmental Disabilities by Residence and Age, Diamond Bar
The California Department of
Developmental Services (DDS) currently
provides community-based services to
persons with developmental disabilities
and their families through a statewide
system of 21 regional centers, four
developmental centers, and two
community-based facilities. The San
Gabriel/Pomona Regional Center
(SG/PRC) located in Pomona
(http://www.sgprc.org/) provides
services to approximately 925 people
with developmental disabilities in
Diamond Bar (Table 9-21). The SG/PRC
is a private, non-profit community
agency that contracts with local
businesses to offer a wide range of
services to individuals with develop-
mental disabilities and their families.
There is no charge for diagnosis and
assessment for eligibility. Once eligibility
is determined, most services are free
regardless of age or income. There is a
requirement for parents to share the
cost of 24-hour out-of-home
placements for children under age 18.
This share depends on the parents’
ability to pay. There may also be a co-
payment requirement for other
selected services.
Regional centers are required by law to
provide services in the most cost-
effective way possible. They must use
all other resources, including generic
resources, before using any regional
center funds. A generic resource is a
service provided by an agency that
has a legal responsibility to provide
services to the general public and
receives public funds for providing
those services. Some generic agencies
may include the local school district,
county social services department,
Medi-Cal, Social Security Administra-
tion, Department of Rehabilitation and
others. Other resources may include
natural supports. This is help that
disabled persons may get from family,

Elderly
Federal housing data define a
household type as “elderly family” if it
consists of two persons with either or
both age 62 or over. Of Diamond Bar's
3,985 such households, 13.8% earn less
than 30% of the surrounding area
income (compared to 24.2% in the
SCAG region) and 34% earn less than
50% of the surrounding area income
(compared to 30.9% in the SCAG
region) (Table 9-22). Many elderly
persons are dependent on fixed
incomes or have disabilities. Elderly
homeowners may be physically unable
to maintain their homes or cope with
living alone. The housing needs of this
group can be addressed through
smaller units, accessory dwelling units
on lots with existing homes, shared living
arrangements, congregate housing
and housing assistance programs.
Program H-7 (Senior and Workforce
Housing Development) and Program H-
10 (Accessory Dwelling Units) in Section
9.3 will be helpful in addressing the
housing needs of seniors.
Table 9-22: Elderly Households by Income and Tenure, Diamond Bar
The elderly tend to have higher rates of
disabilities than younger persons;
therefore, many of the programs noted
in the previous section also apply to
seniors since their housing needs
include both affordability and
accessibility.
Large Households
Household size is an indicator of need
for large units. Large households are
defined as those with five or more
members. Table 9-23 illustrates the
range of household sizes in Diamond
Bar for owners, renters, and overall. The
most commonly occurring household
size is of two persons (29.2%) and the
second-most commonly occurring
household is of three persons (23.1%).
Diamond Bar has a lower share of
single-person households than the
SCAG region overall (14.1% vs. 23.4%)
and a lower share of 7+ person
households than the SCAG region
overall (1.8% vs. 3.1%). This distribution
indicates that the need for large units
with four or more bedrooms is
expected to be significantly less than
for smaller units. However, large families
needing units with more bedrooms,
generally face higher housing costs,
and as a result may benefit from
several types of assistance. Many of the

SCAG region), 4% are female-headed
and with children (compared to 6.6% in
the SCAG region), and 0.3% are
female-headed and with children
under 6 (compared to 1.0% in the
SCAG region) (Table 9-24). Approxi-
mately 3.9 percent of Diamond Bar's
households were experiencing poverty,
compared to 7.9 percent of households
in the SCAG region (Table 9-25).
Poverty thresholds, as defined by the
ACS, vary by household type. In 2018, a
single individual under 65 was
considered in poverty with an income
below $13,064/year while the threshold
for a family consisting of 2 adults and 2
children was $25,465/year. Many of the

Farm W orkers
Farm workers are traditionally defined
as persons whose primary income is
from seasonal agricultural work.
Diamond Bar was at one time one of
the largest working cattle ranches in
the western United States. However,
urban development and shifts in the
local economy have significantly
curtailed agricultural production within
Los Angeles County. Today, Diamond
Bar is a mostly developed city, with a
strong local economy that is no longer
tied to an agricultural base. According
to recent Census estimates, about 45
Diamond Bar residents were employed
in agricultural, forestry, fishing and
hunting, and only 12 of those were
employed full-time in these industries
(Table 9-26).
The nearest agricultural area to
Diamond Bar is in San Bernardino
County to the east. Since there are no
major agricultural operations within
Diamond Bar and housing costs are
significantly lower in the Inland Empire,
there is little need for farm worker
housing in the City. Many of the policies
and programs described in Section 9.5 -

housing needs, including Program H-3

Homeless Persons
Homelessness is a continuing problem
throughout California and urban areas
nationwide. A homeless count
conducted by the Los Angeles
Homeless Services Authority (LAHSA) in
2020 indicated that on any given day
there are an estimated 63,706 homeless
persons Los Angeles County. These
include families that might be
displaced through evictions, women
and children displaced through
abusive family life, persons with
substance abuse problems, veterans, or
persons with serious mental illness.
Diamond Bar is located within the San
Gabriel Valley Service Planning Area
(SPA), which had a 2020 homeless
estimate of 4,555 people, of which four
unsheltered persons were reported in
Diamond Bar.2
The City has adopted a Homelessness
Response Plan that seeks to both
address the needs of those who are
currently unsheltered and to implement
strategies that can prevent an increase
in incidents of homelessness within the
City. In addition, the City is a member
of the San Gabriel Valley Regional
Housing Trust, a joint powers authority
created to finance the planning and
construction of homeless housing, and
extremely-low-, very-low- and low-
income housing projects. Program H-11

address the needs of the homeless.
ASSISTED HOUSING AT RISK OF CONVERSION
Assisted housing at risk of conversion

no assisted housing units in the City of
Diamond Bar at risk of conversion. There

FUTURE GROWTH NEEDS
Overview of the Regional Housing Needs Assessment
The Regional Housing Needs
Assessment (RHNA) is a key requirement
for local governments to plan for
anticipated growth. The RHNA
quantifies the anticipated need for
housing within each jurisdiction for the
6th Housing Element cycle extending
from July 2021 to October 2029.
Communities then determine how they
will address this need through the
process of updating the Housing
Elements of their General Plans.
The RHNA for the 6th cycle was
adopted by the Southern California
Association of Governments (SCAG) in
March 2021. The need for housing is
determined by the forecasted growth
in households as well as existing need
due to overcrowding and
overpayment. Each new household
created by a child moving out of a
parent’s home or by a family moving to
a community creates the need for a
housing unit. The housing need for new
households is then adjusted to maintain
a desirable level of vacancy to
promote housing choice and mobility.
An adjustment is also made to account
for units lost due to demolition, natural
disaster, or conversion to non-housing
uses. Total housing need is then
distributed among four income
categories on the basis of the county’s
income distribution, with adjustments to
avoid an over-concentration of lower-
income households in any community.
More information about the RHNA
process may be found on SCAG’s
website at https://scag.ca.gov/rhna.
2021-2029 Diamond Bar Growth Needs
The total housing growth need for the
City of Diamond Bar during the 2021-
2029 planning period is 2,521 units. This
total is distributed by income category
as shown in Table 9-27.

It should be noted that SCAG did not
identify growth needs for the extremely-
low-income category in the RHNA. As
provided in Assembly Bill (AB) 2634 of
2006, jurisdictions may determine their
extremely-low-income need as one-
half the need in the very-low category.
The City’s inventory of land to
accommodate the RHNA allocation is

9.3 RESOURCES AND OPPORTUNITIES
A variety of resources are available for
the development, rehabilitation, and
preservation of housing in the City of
Diamond Bar. This section provides a
description of the land resources and
adequate sites to address the City’s
regional housing need allocation, and
discusses the financial and administra-
tive resources available to support the
provision of affordable housing.
Additionally, opportunities for energy
conservation that can lower utility costs
and increase housing affordability are
addressed.
LAND RESOURCES
Section 65583(a)(3) of the California
Government Code requires Housing
Elements to include an “inventory of
land suitable for residential develop-
ment, including vacant sites and sites
having potential for redevelopment,
and an analysis of the relationship of
zoning and public facilities and services
to these sites.” A detailed analysis of
vacant land and potential redevelop-
ment opportunities is provided in
Appendix B, Table B-1, which shows
that the City’s land inventory, including
projects approved and the potential
development of vacant and
underutilized parcels, is sufficient to
accommodate the RHNA for this
planning period in all income
categories.
A discussion of public facilities and
infrastructure needed to serve future
development is contained in “Non-
Governmental Constraints” in
Section 9.4. There are currently no
known service limitations that would
preclude the level of development
described in the RHNA, although
developers will be required to pay fees
or construct public improvements prior
to or concurrent with development.
FINANCIAL AND ADMINISTRATIVE RESOURCES
State and Federal Resources
Community Development Block Grant
Program (CDBG) - Federal funding for
housing programs is available through
the Department of Housing and Urban
Development (HUD). Diamond Bar
participates in the Community
Development Block Grant (CDBG)
program and receives its allocation of
CDBG funds through the Los Angeles
County Development Authority
(LACDA). The CDBG program is very
flexible in that the funds can be used
for a wide range of activities. The
eligible activities include, but are not
limited to, acquisition and/or disposition
of real estate property, public facilities
and improvements, relocation,
rehabilitation and construction of
housing, homeownership assistance,
and clearance activities. In 2002 the
City Council approved the
establishment of a Home Improvement
Program (HIP) to provide housing
rehabilitation assistance to qualified
low- and moderate-income
households. CDBG funds are allocated
to the HIP on an annual basis. HIP funds
are used for exterior property
7.2.c
Packet Pg. 93
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-27
9.0
improvements and for repairs to
alleviate health and safety issues and
to correct code violations. In addition,
HIP funds may be used to improve
home access to disabled persons and
for the removal of lead-based paint
hazards.
The City’s CDBG allocation for the 2020-
21 Program Year was $243,522, which
included an allocation for the HIP of
$100,000. Under CDBG regulations, the
HIP is eligible to receive unexpended
CDBG funds from the previous fiscal
year that are reallocated by the
LACDA. Each household that qualifies
for the HIP program is eligible to receive
up to $20,000 as a no-interest, deferred
loan. The City actively promotes the
program and consistently exhausts its
funding allocation each year.
The City anticipates receiving
approximately $232,000 in CDBG funds
from LACDA during 2021-22.
Section 8 Rental Assistance – The City of
Diamond Bar cooperates with the
LACDA, which administers the Section 8
Voucher Program. The Section 8
program provides rental assistance to
low-income persons in need of
affordable housing. There are two types
of subsidies under Section 8: certificates
and vouchers. A certificate pays the
difference between the fair market rent
and 30% of the tenant’s monthly
income, while a voucher allows a
tenant to choose housing that may
cost above the fair market figure, with
the tenant paying the extra cost. The
voucher also allows the tenant to rent a
unit below the fair market rent figure
with the tenant keeping the savings.
Low-Income Housing Tax Credit
Program - The Low-Income Housing Tax
Credit Program was created by the Tax
Reform Act of 1986 to provide an
alternate method of funding low-and
moderate-income housing. Each state
receives a tax credit, based upon
population, toward funding housing
that meets program guidelines. The tax
credits are then used to leverage
private capital into new construction or
acquisition and rehabilitation of
affordable housing. Limitations on
projects funded under the Tax Credit
programs include minimum require-
ments that a certain percentage of
units remain rent-restricted, based upon
median income, for a term of 15 years.
Local Resources
Tax Exempt Multi-Family Revenue
Bonds – The construction, acquisition,
and rehabilitation of multi-family rental
housing developments can be funded
by tax exempt bonds which provide a
lower interest rate than is available
through conventional financing.
Projects financed through these bonds
are required to set aside 20% of the
units for occupancy by very low-
income households or 40% of the units
to be set aside for households at 60% of
the area median income (AMI). Tax
exempt bonds for multi-family housing
may also be issued to refinance existing
tax-exempt debt, which is referred to as
a refunding bond issue.
The Seasons Diamond Bar Senior
Apartments was refinanced in 1999
under the California Community
Development Authority’s Multifamily
Housing Re-funding Bond. According to
the terms of the new bond agreement,
income restrictions for residents and
corresponding rent limits were set. For
7.2.c
Packet Pg. 94

the duration of the bond which expires
in December of 2034, all units will be
affordable: 30 units will be very low
income at 50% AMI, 82 units will be low
income at 80% AMI, and 37 units will be
moderate income at 100% AMI. The
Seasons Apartments are owned by the
Corporate Fund for Housing, a non-
profit organization.
Housing Agreements – The City can
assist in the development of new
affordable housing units by entering
into Disposition Development Agree-
ments (DDA) or Owner Participation
Agreements (OPA) with developers.
DDAs or OPAs may provide for the
disposition of Agency-owned land at a
price which can support the develop-
ment of units at an affordable housing
cost for low- and moderate-income
households. These agreements may
also provide for development
assistance, usually in the form of a
density bonus or the payment of
specified development fees or other
development costs which cannot be
supported by the proposed
development.
Mortgage Credit Certificates – The
Mortgage Credit Certificates (MCC)
program3 is designed to help low- and
moderate-income first-time home-
buyers qualify for conventional first
mortgage loans by increasing the
homebuyer’s after-tax income. The
MCC is a direct tax credit for eligible
homebuyers equal to 20% of the
mortgage interest paid during the year.
The other 80% of mortgage interest can
still be taken as an income deduction.

Diamond Bar is a participating city in
the County-run MCC program.
Home Ownership Program – The Home
Ownership Program (HOP) provides
assistance to low-income, first-time
homebuyers in purchasing a home. It is
administered by the Los Angeles
County Development Authority’s
Housing Development and Preservation
Division. The program has provided
hundreds of Los Angeles County
residents with the means to afford to
fulfill their dream of home ownership.
The maximum gross annual income for
eligible participants is 80% of the
median income for Los Angeles
County.
Southern California Home Financing
Authority Programs – SCHFA4 is a joint
powers authority between Los Angeles
and Orange Counties formed in 1988 to
issue tax-exempt mortgage revenue
bonds for low- to moderate-income
First-Time Homebuyers. SCHFA has
helped thousands of individuals and
families fulfill their dreams of owning a
home. This program makes buying a
home more affordable for qualifying
homebuyers by offering a competitive
30-year fixed rate loan and a grant for
down-payment and closing costs
assistance. The program is administered
by the Los Angeles County
Development Authority and the Public
Finance Division of the County of
Orange. SCHFA does not lend money
directly to homebuyers. Homebuyers
must work directly with a participating
lender. The income limit for Los Angeles
County households as of 2021 is
$135,120.

Fannie Mae Down Payment Assistance
Program5 – The Federal National
Mortgage Association, known as
“Fannie Mae,” offers a program that
provides second mortgages to
homeowners. The second mortgage
can serve as the down payment and
closing costs on home purchases.
Under this program, a city or county is
required to post a reserve fund equal to
20% of an amount that Fannie Mae
then makes available for such
mortgages.
Non-Profit Organizations – Non-profit
organizations play a major role in the
development of affordable housing in
Los Angeles County. LACDA supple-
ments its own efforts of producing
affordable housing by entering into
partnerships with private sector and
non-profit developers and housing
development corporations.
ENERGY CONSERVATION OPPORTUNITIES
As residential energy costs rise, the
subsequent increasing utility costs
reduce the affordability of housing.
Although the City is mostly developed,
new infill development and rehabilita-
tion activities could occur, allowing the
City to directly affect energy use within
its jurisdiction.
State of California Energy Efficiency
Standards for Residential and
Nonresidential Buildings were
established in 1978 in response to a
legislative mandate to reduce
California's energy consumption. The
standards are codified in Title 24 of the
California Code of Regulations and are
updated periodically to allow
consideration and possible incorpora-
tion of new energy efficiency
technologies and methods. The most
recent update to State Building Energy
Efficiency Standards were adopted in
2019. Building Energy Efficiency
Standards have saved Californians
billions of dollars in reduced electricity
bills. They conserve nonrenewable
resources, such as natural gas, and
5 https://singlefamily.fanniemae.com/originating-underwriting/mortgage-products/shared-

6 California Energy Commission (https://www.energy.ca.gov/programs-and-
topics/programs/building-energy-efficiency-standards )
ensure renewable resources are
extended as far as possible so power
plants do not need to be built.6
Title 24 sets forth mandatory energy
standards and requires the adoption of
an “energy budget” for all new
residential buildings and additions to
residential buildings. Separate
requirements are adopted for “low-rise”
residential construction (i.e., no more
than three stories) and non-residential
buildings, which includes hotels, motels,
and multi-family residential buildings
with four or more habitable stories. The
standards specify energy saving design
for lighting, walls, ceilings and floor
installations, as well as heating and
cooling equipment and systems, gas
cooling devices, conservation
standards and the use of non-depleting
energy sources, such as solar energy or
wind power. The home building industry
must comply with these standards while
localities are responsible for enforcing
the energy conservation regulations

through the plan check and building
inspection processes.
In addition to State energy regulations,
the City encourages energy efficiency
through its Climate Action Plan7 and
Home Improvement Program, which
provides low- and moderate-income
households funds for home improve-
ments that may include insulation and
energy-efficient windows and doors.
The City also encourages mixed-use
development, which facilitates energy
efficiency by reducing vehicular trip
lengths. The City also publishes a
monthly Diamond Bar Connection
newsletter at
https://www.diamondbarca.gov/208/D
iamond-Bar-Connection---Monthly-
Newslet, which informs residents of
energy conservation tips and cost
saving programs through the various
utility providers.

9.4 CONSTRAINTS
This section evaluates potential
constraints to the development,
maintenance and improvement of
housing, and identifies appropriate
steps to mitigate potential constraints,
where feasible. Potential constraints to
housing are discussed below, and
include both governmental and non-
governmental factors.
GOVERNMENTAL CONSTRAINTS
Governmental regulations, while
intended to protect the public health,
safety and welfare, can also
unintentionally increase the cost of
housing. Potential governmental
constraints include land use controls,
building codes and their enforcement,
site improvements, fees and other
exactions required of developers, and
local development processing and
permit procedures.
Land Use Plans and Regulations
General Plan
Each city and county in California must
prepare a comprehensive, long-term
General Plan to guide its future. The
land use element of the General Plan
establishes the basic land uses and
density of development within the
various areas of the City. Under State
law, the General Plan elements must
be internally consistent and the City’s
zoning and development regulations
must be consistent with the General
Plan. Thus, the land use plan must
provide suitable locations and densities
to implement the policies of the
Housing Element.
In 2019 the City adopted a
comprehensive General Plan update8
that provides guiding policies for land
use and development through the 2040
horizon year. The 2040 Diamond Bar
General Plan Land Use Element
provides for seven residential land use
designations and four mixed-use
designations allowing residential use, as
shown in Table 9-28.
The Land Use & Economic
Development Chapter designates
approximately 5,148 acres (54%) of the
land area within City limits for residential
uses, and mixed-use designations
allowing residential use comprise an
additional 284 acres. These land use
designations provide for a wide range
of residential types and densities
throughout the City.

General Plan Focus Areas
The 2040 General Plan identifies four
focus areas where major land use
changes are planned as part of a
strategy to provide walkable mixed-use
activity centers. These focus areas
provide opportunities for infill develop-
ment that can incorporate a range of
housing, employment, and recreational
uses to meet the needs of families,
young people, senior citizens, and
residents of all incomes. These focus
areas were designed in response to
community priorities including a desire
for expanded access to entertainment
and community gathering places, and
the need to accommodate the City’s
growing and diverse population. New
land use designations were established
for each of these focus areas to
facilitate development, as described
under Land Use Classifications, below.
In these focus areas, maximum
development is expressed as dwelling
units per gross site area and floor area
ratio (FAR), which is the ratio between
building floor area and lot area.
• The Town Center Mixed Use focus
area, located along Diamond Bar
Boulevard between SR-60 and
Golden Springs Drive, is intended
to build on the success of recent
commercial redevelopment in
that area. The Town Center is
designated for mixed-use
development that would serve as
a center of activity for residents
and provide housing,
entertainment and retail
opportunities and community
gathering spaces in a pleasant,
walkable environment. A
maximum residential density of
20.0 dwelling units per acre and
maximum FAR of 1.5 are
permitted.
• The Neighborhood Mixed Use
focus area is envisioned as a
combination of residential and
ancillary neighborhood-serving
retail and service uses to promote
revitalization of the segment of
North Diamond Bar Boulevard
between the SR-60 interchange
and Highland Valley Road. This
neighborhood has potential to
benefit from its proximity to Mt.
San Antonio College and Cal Poly
Pomona. This land use designation
has an allowable residential
density of up to 30.0 dwelling units
per acre and a maximum FAR of
1.25.
• The Transit-Oriented Mixed Use
focus area leverages underutilized
sites adjacent to the Metrolink
commuter rail station to provide
for higher-density housing, offices,
and supporting commercial uses
close to regional transit. This focus
area allows for new employment
and housing development in a
key location that emphasizes
multi-modal transportation
options. This General Plan
designation allows residential
development at a density of 20.0
to 30.0 dwelling units per acre and
a maximum FAR of 1.5.
• The Community Core focus area
covers the existing Diamond Bar
Golf Course, which is currently
operated by Los Angeles County.
Should the County choose to
discontinue operation of the golf
course or to reduce its size, the
Community Core would be the
City’s preferred approach to
reuse of the site. The Community
Core is envisioned as a master-
planned mixed-use, pedestrian-
oriented community and regional
destination. The majority of the
northern portion is envisioned to
7.2.c
Packet Pg. 100
9-34 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
support a park or consolidated
golf course along with additional
community or civic uses. The
southern portion is envisioned to
accommodate a mix of uses
emphasizing destination and
specialty retail, dining, and
entertainment, including
opportunities for residential,
hospitality, and community and
civic uses. This location benefits
from proximity to the freeways
and nearby commercial uses. The
General Plan does not specify
density or intensity standards for
this focus area and a master plan
will be required for the entire
property to ensure its cohesive
development.
Zoning Designations
The City regulates the type, location,
density, and scale of residential
development through the Develop-
ment Code (Title 22 of the Diamond Bar
Municipal Code) and Zoning Map.
These regulations serve to implement
the General Plan and are designed to
protect and promote the health,
safety, and general welfare of
residents. The Development Code and
Zoning Map set forth residential
development standards and review
procedures for each zoning district.
The seven zoning districts that allow
residential units as a permitted use are
as follows:
RR Rural Residential
RL Low Density Residential
RLM Low Medium Density
Residential
RM Medium Density Residential
RMH Medium High Density
Residential
RH High Density District
RH-30 High Density District (30 units
per acre)
A summary of the development
standards for these zoning districts is
provided in Table 9-29. These develop-
ment standards provide for a range of
housing types and do not create
unreasonable constraints on the
development of housing.

4. SROs are conditionally permitted in the I (light industrial) zone
The Development Code provides for a
variety of housing types including
single-family homes (both attached
and detached), multi-family (both
7.2.c
Packet Pg. 102

rental and condominiums),
manufactured housing, special needs
housing, and accessory dwelling units.
Effect of Zoning and Development
Standards on Housing Supply and
Affordability
Development standards can affect the
feasibility of development projects,
particularly housing that is affordable to
lower- and moderate-income
households. The most significant of
these standards is density. Higher
densities generally result in lower per-
unit land costs, thereby reducing
overall development cost, although this
is not always the case. For example, at
some point higher density may require
more expensive construction methods
such as parking structures, or below-
grade garages.
Pursuant to AB 2348 of 2004, the
“default density” for Diamond Bar is 30
dwelling units per acre9. The default
density refers to the density at which
lower-income housing development is
presumed to be feasible, although
State law allows jurisdictions to propose
alternative densities that are sufficient
to facilitate affordable housing based
on local experience and
circumstances. The RH-30 district allows
multi-family development at the default
density of 30 units per acre. In addition,
the Neighborhood Mixed Use and
Transit-Oriented Mixed Use land use
designations allow residential
development at up to 30 units/acre.
The City is currently in the process of
updating the Development Code to
establish regulations consistent with
these new General Plan land use
designations (see Program H-8 in
Section 9.5).
9 Memo of June 20, 2012 from California Department of Housing and Community Development.
Although appropriate development
standards are necessary for affordable
housing to be feasible, large public
subsidies are typically necessary to
reduce costs to the level that lower-
income households can afford.
Special Needs Housing
Persons with special needs include
those in residential care facilities,
persons with disabilities, the elderly,
farm workers, persons needing
emergency shelter or transitional living
arrangements, and single room
occupancy units. The City’s provisions
for these housing types are discussed
below.
Residential Care Facilities
Residential care facilities refer to any
family home, group home, or
rehabilitation facility that provides non-
medical care to persons in need of
personal services, protection, super-
vision, assistance, guidance, or training
essential for daily living. The
Development Code explicitly
references Residential Care Homes
(§22.80.020). In accordance with State
law, residential care homes that serve
six or fewer persons are permitted by-
right in all residential districts with only a
ministerial zoning clearance required.
Residential care homes serving more
than six persons are permitted by
conditional use permit in the RM, RMH,
and RH Districts. There are no
separation requirements for residential
care facilities. These provisions are
consistent with State law and do not
pose a significant constraint on the
establishment of such facilities.

Definition of Family
Development Code §22.80.020 defines
family as “one or more persons living
together as a single housekeeping unit
in a dwelling unit.” Single housekeeping
unit means “the functional equivalent
of a traditional family, whose members
are an interactive group of persons
jointly occupying a single dwelling unit,
including the joint use of and
responsibility for common areas, and
sharing household activities and
responsibilities such as meals, chores,
household maintenance, and
expenses, and where, if the unit is
rented, all adult residents have chosen
to jointly occupy the entire premises of
the dwelling unit, under a single written
lease with joint use and responsibility for
the premises, and the makeup of the
household occupying the unit is
determined by the residents of the unit
rather than the landlord or property
manager.” These definitions are
consistent with fair housing law and do
not pose an unreasonable constraint to
housing.
Housing for Persons with Disabilities
Both the federal Fair Housing Act and
the California Fair Employment and
Housing Act impose an affirmative duty
on local governments to make
reasonable accommodations (i.e.,
modifications or exceptions) in their
zoning laws and other land use
regulations when such accommoda-
tions may be necessary to afford
disabled persons an equal opportunity
to use and enjoy a dwelling. The
Building Codes adopted by the City of
Diamond Bar incorporate accessibility
standards contained in Title 24 of the
California Administrative Code. For
example, apartment complexes of
three or more units and condominium
complexes of four or more units must
be designed to accessibility standards.
Compliance with building codes and
the Americans with Disabilities Act
(ADA) may increase the cost of housing
production and can also impact the
viability of rehabilitation of older
properties required to be brought up to
current code standards. However,
these regulations provide minimum
standards that must be complied with
to ensure the development of safe and
accessible housing.
Senate Bill 520 of 2001 requires cities to
make reasonable accommodation in
housing for persons with disabilities. The
City has adopted procedures
(Development Code §22.02.060) for
reviewing and approving requests for
reasonable accommodation for
persons with disabilities consistent with
State law.
The director, planning commission or
city council shall approve a request for
a reasonable accommodation subject
to the following findings:
1. The housing, which is the subject of
the request for reasonable
accommodation, will be occupied as
the primary residence by an individual
protected under the Fair Housing Laws.
2. The request for reasonable
accommodation is necessary to make
specific housing available to one or
more individuals protected under the
Fair Housing Laws.
3. The requested reasonable
accommodation will not impose an
undue financial or administrative
burden on the city, as "undue financial
or administrative burden" is defined in
fair housing laws and interpretive case
law.
7.2.c
Packet Pg. 104
9-38 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
4. The requested accommodation will
not result in a fundamental alteration of
the nature of the city's zoning or
building laws, and policies and
procedures, as "fundamental
alteration" is defined in fair housing laws
and interpretive case law.
In making a decision regarding the
reasonableness of the requested
accommodation, the following factors
may be considered:
1. Whether the requested
accommodation will affirmatively
enhance the quality of life of one or
more individuals with a disability.
2. Whether the individual or individuals
with a disability will be denied an equal
opportunity to enjoy the housing type
of their choice absent the
accommodation.
3. In the case of a residential care
facility or sober living home or similar
group home for the disabled, whether
the existing supply of facilities of a
similar nature and operation in the
community is sufficient to provide
individuals with a disability an equal
opportunity to live in a residential
setting.
4. Whether the requested
accommodation would fundamentally
alter the character of the
neighborhood;
5. Whether the accommodation would
result in a substantial increase in traffic
or insufficient parking;
6. Whether granting the requested
accommodation would substantially
undermine any express purpose of
either the city's general plan or an
applicable specific plan;
7. In the case of a residential care
facility or sober living home or similar
group home for the disabled, whether
the requested accommodation would
create an institutionalized environment
due to the number of and distance
between facilities that are similar in
nature or operation.
Farm Worker Housing
As discussed in Section 9.2, Housing
Needs Assessment, the City of Diamond
Bar has no major agricultural areas and
no significant need for permanent on-
site farm worker housing. Commercial
agriculture is not permitted in any
residential zoning district. The City’s
overall efforts to provide and maintain
affordable housing opportunities will
help to support the few seasonal farm
workers that may choose to reside in
the City.
Housing for the Elderly
Senior housing projects are a permitted
use in all residential districts. A density
bonus is also permitted for the
construction of senior housing pursuant
to Government Code §§65915-65918.
Development Code §22.30.040
establishes reduced parking
requirements for senior housing of 1
space for each unit with half the
spaces covered, plus 1 guest parking
space for each 10 units. These
regulations are not considered to be a
constraint to the development of senior
housing because the regulations are
the same as for other residential uses in
the same districts.
Emergency Shelters, Transitional/
Supportive Housing and Low Barrier
Navigation Centers
Emergency shelters are facilities that
provide a safe alternative to the streets
either in a shelter facility, or through the
7.2.c
Packet Pg. 105
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-39
9.0
use of motel vouchers. Emergency
shelter is short-term and usually for 30
days or less. Transitional housing is
longer-term, typically up to 2 years,
while supportive housing may have no
occupancy limit. Programs that
operate transitional and supportive
housing generally require that the
resident participate in a structured
program to work toward established
goals so that they can move on to
permanent housing and may include
supportive services such as counseling.
SB 2 of 2007 strengthened the planning
requirements for emergency shelters
and transitional/supportive housing. This
bill requires jurisdictions to evaluate
their need for shelters compared to
available facilities to address the need.
If existing shelter facilities are not
sufficient to accommodate the need,
jurisdictions must designate at least one
zone where year-round shelters can be
accommodated. There are currently
no emergency shelters located in the
City. As noted in Section 9.2, the most
recent homeless survey reported 4
homeless persons living in Diamond Bar.
To reduce constraints to the establish-
ment of emergency shelters, the
Development Code was amended to
allow shelters with up to 30 beds by-
right in the Light Industrial (I) zone
subject to objective development
standards. This zone encompasses
approximately 98 acres with an
average parcel size of 1.6 acres and
contains underutilized parcels and
vacant buildings that could accommo-
date at least one emergency shelter.
In 2019 the San Gabriel Valley Council
of Governments initiated a study to
assess the needs of the homeless and
develop a coordinated strategy to
address those needs. As a member
jurisdiction, Diamond Bar is cooperating
in this study and is committed to a fair-
share approach to providing the
necessary services and facilities for the
homeless persons and families
identified in the community.
SB 2 also requires that transitional and
supportive housing be considered a
residential use that is subject only to the
same requirements and procedures as
other residential uses of the same type
in the same zone. The Development
Code establishes regulations for
transitional and supportive housing in
compliance with State law. In 2018 AB
2162 amended State law to require
that supportive housing be a use by-
right in zones where multi-family and
mixed uses are permitted, including
non-residential zones permitting multi-
family uses, if the proposed housing
development meets specified criteria.
Program H-11 in Section 9.5 includes a
commitment to process an
amendment to the Development Code
in compliance with this requirement.
In 2019 the State Legislature adopted
AB 101 establishing requirements
related to local regulation of low barrier
navigation centers, which are defined
as “Housing first, low-barrier, service-
enriched shelters focused on moving
people into permanent housing that
provides temporary living facilities while
case managers connect individuals
experiencing homelessness to income,
public benefits, health services, shelter,
and housing.” Low Barrier means best
practices to reduce barriers to entry,
and may include, but is not limited to:
(1) The presence of partners if it is
not a population-specific site,
such as for survivors of domestic
violence or sexual assault,
women, or youth
7.2.c
Packet Pg. 106
9-40 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
(2) Accommodation of residents’
pets
(3) The storage of possessions
(4) Privacy, such as partitions
around beds in a dormitory
setting or in larger rooms
containing more than two beds,
or private rooms”
Low barrier navigation centers meeting
specified standards must be allowed
by-right in areas zoned for mixed use
and in nonresidential zones permitting
multi-family uses. Program H 11 in
Section 9.5 includes a commitment to
process an amendment to the
Development Code in compliance with
this requirement.
Single Room Occupancy
Single room occupancy (SRO) facilities
are small studio-type units and are
conditionally permitted in the Light
Industrial District pursuant to Sec.
22.42.160 of the Development Code.
Development standards for these uses
do not pose an unreasonable
constraint to SRO development.
Off-Street Parking Requirements
The City’s current parking requirements
for residential uses vary by residential
type. Single-family dwellings and
duplex housing require two parking
spaces per unit in a garage. Mobile
homes require two parking spaces plus
guest parking. Studio units require one
space for each unit in a garage, plus
guest parking. Multi-family dwellings,
condos, and other attached dwellings
are required to have two spaces in a
garage for each unit plus 0.5 space for
each bedroom over two, and guest
parking. Accessory dwelling units are
required to have one space in addition
to that required for the single-family
unit. Senior housing projects are
required to provide one space for each
unit with half of the spaces covered,
plus one guest parking space for each
ten units. Senior congregate care
facilities are required to have 0.5 space
for each residential unit, plus one space
for each four units for guests and
employees. Extended care facilities are
required to provide one space for each
three beds the facility is licensed to
accommodate. These parking
requirements are summarized in Table
9-31.
The City is currently preparing an
update to the Development Code to
reflect new policies contained in the
2040 General Plan. Examples of
General Plan parking policies that will
be implemented through revised
development regulations include the
following:
• LU-P-15) Encourage mixed-
use development in infill areas
by providing incentives such as
reduced parking requirements
and/or opportunities for shared
parking.
• LU-P-32) In conjunction with
new development, implement
an overall parking strategy for
the Transit-Oriented Mixed-Use
neighborhood, including
consolidation of smaller parking
lots and district-wide
management of parking
resources.
• LU-P-33 Consider
amendments to the
Development Code parking
regulations as needed to allow
lower parking minimums for
developments with a mix of uses
with different peak parking
needs, as well as developments
7.2.c
Packet Pg. 107
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-41
9.0
that implement enforceable
residential parking demand
reduction measures, such as
parking permit and car share
programs.
• LU-P-43) When updating the
Development Code’s parking
standards or preparing specific
plans, evaluate parking ratios for
the Town Center to balance the
financial feasibility of
development projects with the
provision of adequate parking
for visitors. Coordinate with
developers and transit agencies
to the extent possible to provide
alternative modes of
transportation to allow for
reduced parking requirements.
• CC-P-26) 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.
• CC-P-49) Encourage
reductions in surface parking
and allow for the development
of consolidated parking
structures, provided that they
are screened from view from
Diamond Bar Boulevard and
Golden Springs Drive.
• CR-P-37) Ensure that secure
and convenient bicycle parking
is available at major destinations
such as the Town Center,
commercial centers, transit
stops, schools, parks, multi-family
housing, and large employers.
• CR-G-14) Provide adequate
parking for all land use types,
while balancing this against the
need to promote walkable,
mixed-use districts and
neighborhoods in targeted
areas, and promoting ride-
sharing and alternative
transportation modes.
• CR-P-53) Update parking
standards in the Development
Code to ensure that they are
reflective of the community’s
needs, using current data on
parking demand and taking into
consideration demographics
and access to alternative modes
of transportation.
• CR-P-54) Incorporate
criteria in the Development
Code to allow reductions in
parking requirements in
exchange for VMT reduction
measures.
These policies will be implemented
through revisions to required parking as
part of the Development Code (see
Program H-8) and will minimize the
effect of required parking as a
constraint on the production of
affordable housing.

Accessory Dwelling Units
Accessory dwelling units (ADUs) provide
an important source of affordable
housing for seniors, young adults,
caregivers and other low- and
moderate-income segments of the
population. In recent years, the State
Legislature has adopted extensive
changes to ADU law to encourage
housing production. Among the most
significant changes is the requirement
for cities to allow one ADU plus one
“junior ADU” on single-family residential
lots by-right subject to limited develop-
ment standards. In 2021 the City
amended ADU regulations in
conformance with current law, and
Program H-10 in Section 9.5 includes a
commitment to continue to encourage
ADU production.
Density Bonus
Under Government Code §§65915-
65918, a density increase over the
otherwise maximum allowable
residential density under the Municipal
Code is available to developers who
agree to construct housing develop-
ments with units affordable to low- or
moderate-income households or senior
citizen housing development. AB 2345
of 2019 amended State law to revise
density bonus incentives that are
available for affordable housing
developments. Program H 12 in
Section 9.5 includes a commitment to
amend the Development Code to
include these changes to State density
bonus law.
Mobile Homes/Manufactured
Housing
There is often an economy of scale in
manufacturing homes in a plant rather
than on site, thereby reducing cost. State
law precludes local governments from
prohibiting the installation of mobile
homes on permanent foundations on
single-family lots. It also declares a
mobile home park to be a permitted
land use on any land planned and
zoned for residential use, and prohibits
7.2.c
Packet Pg. 109
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-43
9.0
requiring the average density in a new
mobile home park to be less than that
permitted by the Municipal Code.
In the City of Diamond Bar, manufac-
tured housing is allowed in all residential
zones as a permitted use provided the
installation complies with the site
development standards for the
applicable zoning district. Mobile home
parks are allowed as conditional use
within all residential districts. There are
two mobile home parks in Diamond Bar,
both located in the western portion of
the City: Diamond Bar Estates and
Walnut Creek Estates.
Condominium Conversions
In order to reduce the impacts of
condominium conversions on residents of
rental housing, some of which provides
housing for low- and moderate-income
persons, the City’s Municipal Code
requires that in addition to complying
with all of the regulations and noticing
requirements of the Subdivision Map Act
for condo conversions, the applicant
must propose a relocation assistance
program that will assist tenants displaced
through the conversion in relocating to
equivalent or better housing, assess the
vacancy rate in multi-family housing
within the City, and provide a report to
all tenants of the subject property at
least three days prior to the hearing.
When a condo conversion is permitted,
the increase in the supply of less
expensive for-sale units helps to
compensate for the loss of rental units.
The ordinance to regulate condominium
conversions is reasonable to preserve
rental housing opportunities and does not
present an unreasonable constraint on
the production of ownership housing.
Building Codes
State law prohibits the imposition of
building standards that are not
necessitated by local geographic,
climatic or topographic conditions and
requires that local governments making
changes or modifications in building
standards must report such changes to
the Department of Housing and
Community Development and file an
expressed finding that the change is
needed.
The City’s building codes are based
upon the California Building, Plumbing,
Mechanical and Electrical Codes.
These are considered to be the
minimum necessary to protect the
public's health, safety and welfare. No
additional regulations have been
imposed by the City that would
unnecessarily add to housing costs.
Building Codes are enforced primarily
through the plan check and building
inspection process.
DEVELOPMENT PROCESSING PROCEDURES
7.2.c
Packet Pg. 110
9-44 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
Residential Permit Processing
State Planning and Zoning Law
provides permit processing require-
ments for residential development.
Within the framework of state require-
ments, the City has structured its
development review process to
minimize the time required to obtain
permits while ensuring that projects
receive careful review. All residential
development is reviewed by City staff
for zoning, building, and fire code
compliance prior to issuance of
building permits.
Processing times vary and depend on
the size and complexity of the project.
Projects reviewed by the Planning
Commission, such as Conditional Use
Permits, typically require between 1
and 2 months to process. Tentative
parcel maps and tentative tract maps
typically require 3 to 6 months to
process. Projects reviewed by the City
Council, such as General Plan and
Zoning Amendments, typically require
between 3 and 6months to process.
Table 9-32 identifies the current review
authority responsible for making
decisions on land use permits and other
entitlements, as well as the estimated
processing time for each type of
application.

Certain steps of the development
process are required by State rather
than local laws. The State has defined
processing deadlines to limit the
amount of time needed for review of
required reports and projects. The
following describes the five-step
development review process in
Diamond Bar:
• Application Submittal.
Applications for land use permits
and other matters pertaining to
the Development Code must be
filed on a City application form,
together with all necessary fees
and/or deposits, exhibits, maps,
materials, plans, reports, and
other information required by the
Development Services
Department. Prior to submitting an
application, applicants are
strongly encouraged to request a
pre-application conference with
staff. The purpose of the pre-
application conference is to
inform the applicant of City
requirements as they pertain to
the proposed development
project, review the procedures
outlined in the Development
Code, explore possible
alternatives or modifications, and
identify necessary technical
studies and required information
related to the environmental
review of the project.
Single-family residential uses are
permitted by-right in all residential
zoning districts. Multi-family
residential uses are permitted by-
right in the RM, RMH and RH zones.
All new residential construction
and some additions to existing
residences are subject to
“Development Review.”
Development Review and
Administrative Development
Review applications for projects
that also require the approval of
another discretionary permit (e.g.
conditional use permit) shall be
acted upon concurrently with the
discretionary permit and the final
determination shall be made by
the highest level of review
authority in compliance with Table
9-32.
Development Review. An applica-
tion for Development Review is
required for residential projects
that propose one or more dwelling
units (detached or attached) and
that involve the issuance of a
building permit for construction or
reconstruction of a structure(s)
meeting the following criteria:
• New construction on a vacant
lot and new structures,
additions to structures, and
reconstruction projects which
are equal to 50% or greater of
the floor area of existing
structures on site, or have 5,001
square feet or more of
combined gross floor area in
any commercial, industrial, and
institutional development; or
• Projects involving a substantial
change or intensification of
land use (e.g. the conversion of
and existing structure to a
restaurant, or the conversion of
a residential structure to an
office or commercial use); or
• Residential, commercial,
industrial, or institutional
projects proposed upon a
descending slope abutting a
public street.
7.2.c
Packet Pg. 112
9-46 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
Administrative Development
Review. An application for
Administrative Development
Review is required for residential,
industrial, and institutional
developments that involve the
issuance of a building permit for
construction or reconstruction of a
structure(s) meeting the following
thresholds of review:
• Commercial, industrial, and
institutional developments that
propose up to 5,000 square
feet of combined floor area; or
• Projects that do not meet the
specific criteria for
Development Review.
Development Review and
Administrative Development
Review are non-discretionary
review procedures intended to
address design issues such as
landscaping and building
massing, and do not include a
review of the merits or suitability of
the use itself.
• Initial Application Review. The
Director reviews all applications
for completeness and accuracy
before they are accepted as
being complete and officially
filed. Processing of applications
does not commence until all
required fees and deposits have
been paid. Without the
application fee or a deposit, the
application is not deemed
complete.
Within 30 days of a submittal, staff
reviews the application package
and the applicant is informed in
writing of whether or not the
application is deemed complete
and has been accepted for
processing. If the application is
incomplete, the applicant is
advised regarding what
additional information is required.
If a pending application is not
deemed complete within 6
months after the first filing with the
Department, the application
expires and is deemed withdrawn.
Any remaining deposit amount is
refunded, subject to
administrative processing fees.
• Environmental Review. After
acceptance of a complete
application, a project is reviewed
for compliance with the California
Environmental Quality Act
(CEQA). A determination is made
regarding whether or not the
proposed project is exempt from
the requirements of CEQA. If the
project is not exempt, a
determination is made regarding
whether a Negative Declaration,
Mitigated Negative Declaration,
or Environmental Impact Report
will be required based on the
evaluation and consideration of
information provided by an initial
study. If an EIR is required, a
minimum of nine months to one
year is typically required to
complete the process.
• Staff Report and Recommenda-
tions. A staff report is prepared by
the Director that describes the
conclusions and findings about
the proposed land use
development. The report includes
recommendations on the
approval, approval with
conditions, or disapproval of the
application. Staff reports are
provided to the applicant at the
same time they are provided to
the Hearing Officer, or members
of the Commission and/or
Council, before a hearing on the
application.

• Notice and Hearings. An
application for a development
review or administrative
development review is scheduled
for a public hearing once the
department has determined the
application complete.
Administrative development
reviews and minor CUPs are heard
by a Hearing Officer (staff) while
more significant applications are
heard by the Planning
Commission. Legislative acts such
as General Plan amendments,
zone changes, specific plans and
development agreements require
City Council approval. Upon
completion of the public hearing,
the review authority shall
announce and record the
decision within 21 days following
the conclusion of the public
hearing. The decision shall contain
the required findings and a copy
of the resolution shall be mailed to
the applicant.
The City is currently preparing a revised
Development Code, which will include
streamlined permit review procedures
and objective standards to ensure that
the development review process does
not act as a constraint to housing
development (see Program 8).
The length of time between project
approval and request for building
permit can vary widely depending on
the size and complexity of the project,
the applicant’s schedule for preparing
building plans and any required
corrections.
Due to high property values and the
shortage of vacant residential land,
development proposals typically seek
to maximize allowable densities unlike
areas further inland where more vacant
land is available.
Development Fees and Improvement Requirements
After the passage of Proposition 13 and
its limitation on local governments’
property tax revenues, cities and
counties have faced increasing
difficulty in providing public services
and facilities to serve their residents.
One of the main consequences of
Proposition 13 has been the shift in
funding of new infrastructure from
general tax revenues to development
impact fees and improvement
requirements on land developers. The
City requires developers to provide on-
site and off-site improvements
necessary to serve their projects. Such
improvements may include water,
sewer and other utility extensions, street
construction and traffic control device
installation that are reasonably related
to the project. Dedication of land or in-
lieu fees may also be required of a
project for rights-of-way, transit facilities,
recreational facilities and school sites,
consistent with the Subdivision Map
Act.
State law limits fees charged for
development permit processing to the
reasonable cost of providing the
service for which the fee is charged.
Various fees and assessments are
charged by the City and other public
agencies to cover the costs of
processing permit applications and
providing services and facilities such as
schools, parks and infrastructure. Table
9-33 provides a list of fees the City of
Diamond Bar charges for new,
standard residential development. The
City periodically evaluates the actual
7.2.c
Packet Pg. 114

cost of processing development
permits when revising its fee schedule.

c (RFD) Deposit based fees will be charged at the fully allocated hourly rates for all personnel involved plus any outside
costs, with any unused portion of a deposit-based fee being refunded to the applicant at the conclusions of the
project. In certain circumstances where project costs are higher than the available deposit, the applicant will be
required to submit additional funds into the deposit account.
d Development impact fees are determined by the project’s scope, location, and existing conditions. The dev eloper
must prepare the appropriate study and provide the report for staff to review. When applicable, public improvements
may be conditioned with, or in lieu of, development impact fees.
e Park fees are determined based on 5 acres of land per 1,000 population per State law
Improvement Requirements
Throughout California, developers are
required to construct on- and off-site
improvements needed to serve new
projects, including streets, sidewalks,
and utilities. City road standards vary by
roadway designation as provided in
Table 9-34.
A local residential street requires a 44-
to 60-foot right-of-way, with two 12-foot
travel lanes. These road standards are
typical for cities in Los Angeles County
and do not act as a constraint to
housing development.
The City’s Capital Improvement
Program (CIP) contains a schedule of
public improvements including streets,
bridges, overpasses and other public
works projects to facilitate the
continued build-out of the City’s
General Plan. The CIP helps to ensure
that construction of public

Although development fees and
improvement requirements increase
the cost of housing, cities have little
choice in establishing such require-
ments due to the limitations on property
taxes and other revenue sources
needed to fund public services and
improvements.
NON-GOVERNMENTAL CONSTRAINTS
Environmental Constraints
Environmental constraints include
physical features such as steep slopes,
fault zones, floodplains, sensitive
biological habitat, agricultural lands,
and wildland fire hazards. In many
cases, development of these areas is
constrained by State and federal laws
(e.g., FEMA floodplain regulations, the
Clean Water Act, the Endangered
Species Act, the State Fish and Game
Code and the Alquist-Priolo Act).
Most of the level, easily buildable land
in Diamond Bar has already been
developed, and much of the remaining
land has a variety of geotechnical and
topographic conditions that may
constrain the development of lower-
priced residential units. Large portions
of the City contain steep slopes that
pose a significant constraint to
development.
In addition to slope constraints, many of
the hillsides in Diamond Bar have a
potential for landslides. Slope stability is
affected by such factors as soil type,
gradient of the slope, underlying
geologic structure, and local drainage
patterns. The rolling topography and
composition of local soils throughout
Diamond Bar create numerous areas
for potential landslide hazards.
Although many historical landslide
locations have been stabilized, a
number of potential landslide areas still
exist in the eastern portion of the City as
well as within Tonner Canyon in the
Sphere of Influence. Figure 9-2 illustrates
the significant areas with geological
constraints.
Wildland fire hazards present another
environmental constraint to housing
development. As seen in Figure 9-3,
significant portions of the city are within
designated fire hazard zones. As the
frequency and intensity of wildfires
have increased in recent years, housing
development becomes more difficult in
these areas.
7.2.c
Packet Pg. 116
9-50 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
Infrastructure Constraints
As discussed under Development Fees
and Improvement Requirements, the
City requires developers to provide on-
site and off-site improvements
necessary to serve their projects.
Dedication of land or in-lieu fees may
also be required of a project for rights-
of-way, transit facilities, recreational
facilities and school sites, consistent
with the Subdivision Map Act.
Additionally, the City’s Capital
Improvement Program (CIP) contains a
schedule of public improvements
including streets and other public works
projects to facilitate the continued
build-out of the City’s General Plan. The
CIP helps to ensure that construction of
public improvements is coordinated
with development. As a result of these
policies, any infrastructure constraints
which currently exist must be fully
mitigated and financed as growth
occurs.
Water and sewer service providers must
establish specific procedures to grant
priority water and sewer service to
developments with units affordable to
lower-income households.
Wastewater
Wastewater conveyance and
treatment in Diamond Bar is provided
by the County of Los Angeles Sanitation
District No. 21. Although much of the
physical sewage infrastructure appears
in generally good condition, there have
been repeated failures of the pump
stations needed to lift flows to the
regional collectors. Presently, there are
no sewer lines in place in the
developed southeastern end of the
1,250-acre development known as the
Country Estates. Approximately 144 lots
are utilizing on-site wastewater disposal
systems.
Water
Water for City residents is supplied by
the Walnut Valley Water District, which
receives its water supply from the Three
Valleys Municipal Water District and
ultimately from the Metropolitan Water
District (MWD) of Southern California.
Almost all of the water supply is
purchased from MWD, which imports
water from the Colorado River
Aqueduct (a small portion comes from
Northern California through the State
Water Project). Domestic water supply
is not expected to limit development
during the planning period.
Storm Water Drainage
Flood control is provided by the County
Flood Control District. Flood control
facilities are in fairly good condition.
Development proposals are assessed
for drainage impacts and required
facilities. With these existing facilities
and review procedures in place, the
City’s flood control system is not
expected to limit development during
the planning period.
Dry Utilities
Dry utilities such as electricity,
telephone and cable are provided by
private companies and are currently
available in the areas where future
residential development is planned.
When new development is proposed
the applicant coordinates with utility
companies to arrange for the extension
of service. There are no known service
limitations that would restrict planned
development during the planning
period.

Land Costs
Land represents one of the most
significant components of the cost of
new housing. Land values fluctuate
with market conditions, and changes in
land prices reflect the cyclical nature
of the residential real estate market.
A major constraint to providing
affordable housing on remaining vacant
hillside parcels in Diamond Bar is the high
cost of construction in hillside areas.
Another cost constraint for construction
in areas with steep topography is the low
ratio of developable area to total land
area. Residential projects in hillside areas
have large amounts of open space and
only about 25-30% developable land.
The estimated value of vacant
residential land is approximately
$10/square foot or more, and values can
vary widely depending on site
conditions.
Construction Costs
Construction cost is affected by the
price of materials, labor, development
standards and general market
conditions. The City has no influence
over materials and labor costs, and the
building codes and development
standards in Diamond Bar are not
substantially different than most other
cities in Los Angeles County.
Construction costs for materials and
labor have increased at a slightly
higher pace than the general rate of
inflation according to the Construction
Industry Research Board. The
International Code Council estimated
that the average construction cost for
good-quality housing was
approximately $131 per square foot for
single-family homes and $119 per
square foot for multi-family housing.
Cost and Availability of Financing
Diamond Bar is typical of Southern
California communities with regard to
private sector home financing
programs. As discussed in the previous
section, Diamond Bar utilizes tax
exempt multi-family revenue bonds
which provide a lower interest rate than
is available through conventional
financing. This program helps to
address funding for low-income multi-
family projects.
Under State law, it is illegal for real
estate lending institutions to
discriminate against entire
neighborhoods in lending practices
because of the physical or socio-
economic conditions in the area
(“redlining”). There is no evidence of
redlining being practiced in any area
of the City.
AFFIRMATIVELY FURTHERING FAIR HOUSING
Under State law, “affirmatively
furthering fair housing” means “taking
meaningful actions, in addition to
combating discrimination, that
overcome patterns of segregation and
foster inclusive communities free from
7.2.c
Packet Pg. 118
9-52 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
barriers that restrict access to
opportunity based on protected
characteristics.”
There are three parts to this
requirement:
1. Include a Program that
Affirmatively Furthers Fair Housing and
Promotes Housing Opportunities
throughout the Community for
Protected Classes (applies to housing
elements beginning January 1, 2019).
2. Conduct an Assessment of Fair
Housing that includes summary of fair
housing issues, an analysis of available
federal, state, and local data and local
knowledge to identify, and an
assessment of the contributing factors
for the fair housing issues.
3. Prepare the Housing Element
land inventory and identification of sites
through the lens of affirmatively
furthering fair housing.
In compliance with AB 686, the City has
completed the following outreach and
analysis.
Outreach
As discussed in Appendix C, the City
held a total of five public meetings
during the Housing Element update in
an effort to include all segments of the
community. Notices prior to each
meeting were sent directly to persons
and organizations with expertise in
affordable housing and supportive
services. Interested parties had the
opportunity to interact with City staff
throughout the Housing Element
update process and provide direct
feedback regarding fair housing issues.
The City also created a dedicated web
page for the Housing Element update
(www.diamondbarca.gov/963/Housing
-Element-Update) where meeting
notices and agenda materials, an FAQ,
and background information were
posted. The City provided opportunities
for interested persons to participate in
public meetings remotely, which made
it possible for those with disabilities
limiting their travel to participate and
comment on the Housing Element
regardless of their ability to attend the
meetings.
Assessment of Fair Housing
The following analysis examines
geographic data regarding racial
segregation, poverty, persons with
disabilities, and areas of opportunity as
identified by the TCAC/HCD
Opportunity Areas map.
Racial segregation. As seen in Figure 9-
4, the percentage of non-white
population in Diamond Bar is similar to
adjacent areas with the exception of a
small area immediately north of the city
that is part of the Cal Poly Pomona
campus (formerly the Lanterman
Developmental Center). This map does
not indicate any patterns of
racial/ethnic concentration or
discrimination in the city.
Poverty. Recent Census estimates
regarding poverty status of households
in Diamond Bar are shown in Figure 9-5.
As seen in this map, the poverty rate is
less than 10% for nearly all areas the
city. One small area in the southwestern
portion of the city near the SR-60
freeway has a slightly higher poverty
rate of 10% to 20%.
Persons with disabilities. The incidence
of disabilities is relatively low in most
parts of Diamond Bar. As shown in
Figure 9-6, the percentage of residents
reporting a disability is less than 10% in
the majority of the city, while the
7.2.c
Packet Pg. 119
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-53
9.0
disability rate is 10% to 20% in the
northern portion of the city.
Access to opportunity. According to
the 2020 California Department of
Housing and Community Development
(HCD) and the California Tax Credit
Allocation Committee (TCAC)
Opportunity Area Map (Figure 9-7),
Diamond Bar is within the Moderate,
High, and Highest Resource areas. High
Resource areas are areas with high
index scores for a variety of
educational, environmental, and
economic indicators. Some of the
indicators identified by TCAC include
high levels of employment and close
proximity to jobs, access to effective
educational opportunities for children
and adults, low concentration of
poverty, and low levels of
environmental pollutants, among
others.
Contributing factors to fair housing
issues. Under the Federal consolidated
planning process, the Analysis of
Impediments (AI) to Fair Housing
Choice is the primary tool for
addressing fair housing issues. The City
of Diamond Bar was a participating city
with the County of Los Angeles in the
preparation of the 2018 AI. Based on
extensive analysis of housing and
community indicators, and the input of
residents, a list of impediments to fair
housing choice was developed.
Appendix D includes a summary of the
contributing factors to fair housing
issues pertaining specifically to the
Urban County and HACoLA’s service
areas. These items are prioritized
according to the following criteria:
1. High: Impediments/Contributing
factors that have a direct and
substantial impact on fair housing
choice, especially in R/ECAP areas,
affecting housing, those impacting
persons with disabilities, and are core
functions of HACoLA or the CDC.
2. Moderate: Impediments/
Contributing factors that have a direct
and substantial impact on fair housing
choice, especially in R/ECAP areas,
affecting housing, those impacting
persons with disabilities, and are core
functions of HACoLA or the CDC, but
the CDC or HACoLA may only have
limited capacity to make a significant
impact; or may not be within the core
functions of HACoLA or the CDC.
3. Low: Impediments/Contributing
factors that may have a direct and
substantial impact on fair housing
choice but are not within the core
functions of HACoLA or the CDC or not
within the capacity of these
organizations to make significant
impact, or not specific to R/ECAP
neighborhoods, or have a slight or
largely indirect impact on fair housing
choice.
The impediments/contributing factors
identified and included in Appendix D
are in relation to the fair housing issues
listed below. The prioritization of these
contributing factors relates to the ability
of the CDC and HACoLA to address
the fair housing issues. A low priority
does not diminish the importance of
the factor in the Urban County or
HACoLA service areas but reflects the
priority in addressing issues of fair
housing.

9.5 HOUSING ACTION PLAN
Sections 9.2 through 9.4 of this Housing
Element describe the housing needs,
opportunities and constraints in the City
of Diamond Bar. This section presents
the City's 8-year Housing Action Plan for
the 2021-2029 planning period. This Plan
sets forth Diamond Bar's goals, policies,
and programs to address the identified
housing needs of the City.
GOALS AND POLICIES
It is the overall goal of the plan that
there be adequate housing in the City,
both in quality and quantity, to provide
appropriate shelter for all without
discrimination.
The goals and policies of the Housing
Element presented below address
Diamond Bar's identified housing needs
and are implemented through a series
of housing programs offered through
the Community Development
Department. Within this overarching
goal, the City has established goals
and policies to address the
development, maintenance and
improvement of the housing stock.
H-G-1 Preserve and conserve the existing housing stock and maintain property
values and residents' quality of life.
H-P-1.1 Continue to offer home improvement and rehabilitation
assistance to low- and moderate-income households, including
seniors and the disabled.

HOUSING PROGRAMS
Housing Element goals and policies are
implemented through a series of
housing programs described below.
Pursuant to §65583 of the Government
Code, a city’s housing programs must
address the following major areas:
• Conserve and improve the
condition of the existing supply of
affordable housing;
• Assist in the development of
adequate housing to meet the
needs of extremely-low, very-low,
low, and moderate-income
households;
• Provide adequate sites to
accommodate the city’s share of
the regional housing need for
households of each income level;
• Remove governmental constraints
to the maintenance,
improvement, and development
of housing, including housing for
all income levels and housing for
persons with disabilities;
• Promote the creation of
accessory dwelling units that can
be offered at affordable rents;
• Affirmatively furthering fair housing
and promote equal housing
opportunity
• Include a diligent effort to
achieve public participation of all
economic segments of the
community in the development of
the housing element.
Diamond Bar’s programs for addressing
these requirements are described in this
section.
Conserve and Improve the Condition of Existing Affordable Housing
Conserving and improving the
condition of the housing stock is an
important goal for Diamond Bar.
Although the majority of the City's
housing stock is in good condition, a
significant portion of the housing stock
is over 30 years old, the age when most
homes begin to require major
rehabilitation improvements. By
identifying older residential neighbor-
hoods for potential housing
rehabilitation, the City has taken a
proactive approach to maintaining the
quality of its current housing stock. The
focus neighborhoods identified by this
Plan as evidencing physical problem
conditions can be specifically targeted
for City housing improvement
assistance.
Program H -1. Residential Neighborhood Improvement Program
The City implements a proactive Neighborhood Improvement Program and
neighborhood inspections are conducted on a regular basis throughout the
entire City. The checklist for residential violations includes inoperable
vehicles, trash storage, parking on paved areas only, structure maintenance,
landscape maintenance, and fence and wall maintenance. After the
neighborhood inspection, letters are sent out to all property owners in areas
where violations have been observed. A follow-up inspection will be
conducted, at which time any noticed properties found to be in violation of
the Municipal Code are subject to a $100 citation.
7.2.c
Packet Pg. 128
9-62 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
When problems are observed, inspectors may refer residents to the Home
Improvement Program (see Program H-2).
Eight-year objective: Continue to implement the code enforcement
program, and direct eligible households to available rehabilitation
assistance to correct code violations. Provide focused code
enforcement and rehabilitation assistance for 5 to 6 households during
the planning period in neighborhoods evidencing concentrations of
deteriorating units.
Responsible agency: Community Development Department.
Timeline: Throughout the planning period.
Program H -2. Home Improvement Program
The City uses CDBG funds for minor home repair through the Home
Improvement Program, where low/moderate income householders may
receive up to a $20,000 no interest, deferred loan for home repair and
rehabilitation. The City promotes and coordinates this program by posting
information, reviewing applications and disbursing grant funds to eligible
applicants.
Eight-year objective: Minor repair and rehabilitation for 4 units annually.
Responsible agency: Community Development Department.
Timeline: Throughout the planning period.
Program H -3. Section 8 Rental Assistance Program
The Section 8 Rental Assistance Program extends rental subsidies to
extremely-low- and very-low-income households who spend more than 30%
of their gross income on housing. Rental assistance not only addresses
housing affordability, but also overcrowding by assisting families that may be
"doubling up" in order to afford rent. The Los Angeles County Development
Authority (LACDA) coordinates Section 8 rental assistance on behalf of the
City. The City will continue to provide rental assistance information and
referrals to LACDA.
Eight-year objective: Continue to direct eligible households to the
County Section 8 program.
Responsible agency: LACDA.
Timeline: Throughout the planning period.
Program H -4. Preservation of Assisted Housing
Diamond Bar contains only one assisted housing project, the 149-unit
Seasons Apartments (formerly Heritage Park) for senior citizens. This project
was constructed in 1988 and was originally financed under the Los Angeles
County Multi-Family Mortgage Revenue Bond program. The project was
7.2.c
Packet Pg. 129
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-63
9.0
refinanced in November 1999 under the California Community Development
Authority's Multi-Family Housing Re-funding Bond, and was transferred to the
Corporate Fund for Housing, a non-profit organization. According to the
terms of the new bond agreement, income restrictions for residents and
corresponding rent limits were set. For the duration of the bond, which
expires December 2, 2034, all units will be affordable: 30 units (20%) will be
very-low-income, 82 units (55%) will be low-income, and 37 units will be
moderate-income (defined as 100% AMI).
Eight-year objective: Preserve 100% of the 149 low- and moderate-
income units in the Seasons Apartments.
Responsible agency: Community Development Department
Timeline : Throughout the planning period Program H-5. Mobile Home Park
Preservation
There are two mobile home parks in Diamond Bar, both located in the
western portion of the City: Diamond Bar Estates and Walnut Creek Estates.
These mobile home parks were developed before incorporation of the City
on land previously designated as Industrial under the County's jurisdiction.
The 2040 Diamond Bar General Plan Land Use Map designates both mobile
home parks "residential" in order to preserve their status and prevent future
inconsistencies. This designation in the General Plan works to preserve the
parks since any proposed land use change would require an amendment to
the City's General Plan and Zoning Ordinance, as well as adherence to State
mobile home park closure requirements.
Eight-year objective: The City will continue to support preservation of its
two mobile home parks as important affordable housing resources.
Responsible agency: Community Development Department
Timeline: Continuously throughout the planning period
Assist in the Development of Affordable Housing
To enable more households to attain
homeownership in Diamond Bar, the
City participates in two mortgage
assistance programs: the Homebuyer
Assistance Program and the Mortgage
Credit Certificate (MCC). These
programs are very important given that
housing prices in Diamond Bar rank
among the highest in eastern Los
Angeles County and northern Orange
County. The City is also supportive of
the development of senior housing to
meet the needs of its growing senior
population and multi-family rental
housing for lower-income households,
including working families and university
students.
Program H -6. First -Time Homebu yer Assistance Programs
Los Angeles County offers a first-time homebuyer assistance program and
Mortgage Credit Certificates. To be eligible, families must meet the specified
7.2.c
Packet Pg. 130
9-64 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
income requirements and be able to pay a 1% down payment on their
home. The City of Diamond Bar provides referral information to prospective
buyers at the public counter and on the City website.
6.a Home Ownership Program (HOP)
The Los Angeles County Home Ownership Program (HOP) provides zero-
interest loans with no repayment due until the home is sold, transferred,
or refinanced. The loan is secured by a second trust deed and a
promissory note. The home must be owner-occupied for the life of the
loan.
6.b Mortgage Credit Certificate (MCC)
The Mortgage Credit Certificate (MCC) program is a federal program
that allows qualified first-time homebuyers to take an annual credit
against federal income taxes of up to 15% of the annual interest paid
on the applicant's mortgage. This enables homebuyers to have more
income available to qualify for a mortgage loan and make the monthly
mortgage payments. The value of the MCC must be taken into
consideration by the mortgage lender in underwriting the loan and
may be used to adjust the borrower's federal income tax withholding.
The MCC program has covenant restrictions to ensure the affordability
of the participating homes for a period of 15 years. MCCs can be used
in conjunction with the Home Ownership Program (HOP).
Eight-year objective: The City will advertise these programs and provide
information to interested homebuyers. In addition, the City will work with
realtors to make them aware of these programs.
Responsible agency: Community Development Department
Timeline: Continuously throughout the planning period
Program H -7. Senior and Workforce Hous ing Development
With a growing portion of the City's population 65 years of age and above,
Diamond Bar will continue to need housing and services for seniors.
Particularly those seniors 75 years and older will begin to require housing with
a supportive service component.
In addition, occupations for which high housing costs make it difficult for
working-age households to live in Diamond Bar include teachers, police and
firefighters. Several colleges and universities are also located within
commuting distance of Diamond Bar. The City will continue to coordinate
with these institutions to identify potential partnership opportunities for
affordable faculty/staff housing.
The City will encourage the development of senior and workforce housing,
including units affordable to very-low- and extremely-low-income persons as
well as units with 3-4 bedrooms suitable for large families, if feasible, in several
7.2.c
Packet Pg. 131
HOUSING ELEMENT
Diamond Bar General Plan 2040 │ HOUSING ELEMENT 2021-2029 9-65
9.0
ways. First, the City will identify suitable sites for multi-family development in
the Housing and Land Use Elements, including zoning to encourage and
facilitate lower-cost housing options such as SROs. Second, the City will offer
regulatory incentives, and/or direct financial assistance appropriate to the
project when feasible. The following are among the types of incentives
which may be provided:
• Priority application processing
• Fee waivers or deferrals
• Coordination with off-site infrastructure improvements
• Flexible development standards
• Density bonuses
City support to developers in affordable housing funding applicationsIt must
be recognized that the City’s ability to offer direct financial subsidies is
limited. The City has no local source of housing assistance funds, and its
CDBG revenue is only about $232,000 per year currently (see Section 9.3 for
further discussion of the City’s financial resources). Given these financial
limitations, the City’s primary efforts to encourage and facilitate affordable
housing production are through its land use regulations and staff support to
interested developers in applying for grant funds, and cooperation with the
Los Angeles County Development Authority (LACDA) on its assistance
programs.
Pursuant to the City's Affordable Housing Incentives Ordinance, the City
provides modified development standards, including parking reductions, for
senior and affordable projects. A portion of the City's CDBG funds can be
used to help finance senior and workforce housing projects. New housing
developments in Diamond Bar may also be eligible for funding sources
identified in Section 9.3, Resources and Opportunities. Typically, local
assistance can serve as gap financing to bridge the difference between the
total project cost and the equity investment plus debt.
Eight-year objective: The City will identify sites suitable for new senior
and workforce housing and post information on the City website
throughout the planning period regarding the City's interest in assisting
in the development of senior and workforce housing, provide
information on available regulatory and financial incentives, and assist
developers in applying for funds. The City will also collaborate with local
colleges and universities to identify potential partnership opportunities
for affordable housing. The City’s quantified objectives for housing
production during the 2021-2029 planning period are described in Table
9-35.

community is the provision of adequate
sites for all types, sizes and prices of
housing. The City's General Plan,
Development Code and specific plans
describe where housing may be built,
thereby affecting the availability of
land for residential development.
Specific housing sites are identified in
Appendix B.
Program H -8. Land Use Element and Development Regulations
The City completed a comprehensive update to the General Plan in 2019.
The Land Use Element of the General Plan, as discussed previously in
Section 9.3, provides for a variety of housing types in Diamond Bar, with
densities ranging up to 30 dwelling units per acre. In addition, the new
General Plan established several “focus areas” where additional
development and redevelopment are encouraged, including multi-family
residential and mixed-use. As described in Appendix B, General Plan land
use designations provide adequate capacity to accommodate the City’s
RHNA allocation at all income levels for the 2021-2029 period. The City is
currently processing amendments to the Development Code to align
development regulations with new General Plan land use designations and
comply with the following requirements pursuant to Government Code Sec.
65583.2(h).
• Permit owner-occupied and rental multifamily uses by right for
developments in which 20 percent or more of the units are affordable
to lower income households. By right means local government review
must not require a conditional use permit, planned unit development
permit, or other discretionary review or approval.
• Permit the development of at least 16 units per site.
• Require a minimum density of 20 units per acre; and
• Ensure a) at least 50 percent of the shortfall of low- and very low-
income regional housing need can be accommodated on sites
designated for exclusively residential uses, or b) if accommodating
more than 50 percent of the low- and very low-income regional
housing need on sites designated for mixed-uses, all sites designated
for mixed-uses must allow 100 percent residential use and require
residential use to occupy at least 50 percent of the floor area in a
mixed-use project.
As part of the Development Code update, residential and mixed-use
parking requirements will be revised in conformance with General Plan
policies described previously in Section 9.4 Constraints.
The Development Code update will also include revisions to streamline the
review process, including SB 35 review procedures and objective standards
to minimize constraints on housing supply and affordability.

The City shall continue to comply with the “no net loss” provisions of
Government Code §65863 through ongoing project-by-project evaluation to
ensure that adequate sites are available to accommodate the City’s RHNA
share throughout the planning period. The City shall not reduce the
allowable density of any site in its residential land inventory, nor approve a
development project at a lower density than assumed in the Housing
Element sites inventory, unless both of the following findings are made:
a) The reduction is consistent with the adopted General Plan,
including the Housing Element; and
b) The remaining sites identified in the Housing Element are adequate
to accommodate the City’s remaining share of regional housing
need pursuant to Government Code §65584.
If a reduction in residential density for any parcel would result in the
remaining sites in the Housing Element land inventory not being adequate to
accommodate the City’s share of the regional housing need pursuant to
§65584, the City may reduce the density on that parcel if findings are made
identifying sufficient additional, adequate and available sites with an equal
or greater residential density so that there is no net loss of residential unit
capacity.
Eight-year objectives: Maintain adequate sites for housing
development at all income levels in conformance with the RHNA and
ensure compliance with No Net Loss requirements. Process a
Development Code amendment within three years of Housing Element
adoption to update land use regulations consistent with the 2040
General Plan.
Responsible agency: Community Development Department
Timeline: Development Code amendment within three years of Housing
Element adoption
Program H -9. Mixed Use Development
The 2040 General Plan encourages mixed-use development in three focus
areas, which could provide housing close to transit and places of
employment (see additional discussion in Appendix B). The City will
encourage property owners and developers to pursue mixed-use
development in these focus areas to accommodate a portion of the city’s
low- and moderate-income housing needs during this planning period.
Mixed-use can also reduce vehicle trips, make more efficient use of land
and parking areas, and facilitate energy conservation.
Incentives the City may offer to encourage and facilitate redevelopment in
these areas include the following:
• Coordination with off-site infrastructure improvements)
• Flexible development standards
• Density bonuses

Housing Element adoption and continuously thereafter
Program H -10. Accessory Dwelling Units
Accessory dwelling units (ADUs) provide an important source of affordable
housing for seniors, young adults and other low- and moderate-income
households. The City adopted an amendment to the Development Code in
2021 to incorporate recent changes to State ADU law, and will continue to
encourage ADU production through public information available at City Hall
and on the City website.
Eight-year objective: Continue to encourage construction of ADUs
through an informational handout available at City Hall and on the City
website throughout the planning period.
Responsible agency: Community Development Department
Timeline: Publish ADU handout with marketing materials within 6 months

Removing Governmental Constraints to Housing
Under current State law, the Housing Element must address, and where legally
possible, remove governmental constraints affecting the maintenance,
improvement, and development of housing. The following programs are designed
to mitigate government constraints on residential development and facilitate the
development of a variety of housing.
Program H -11. Emergency Shelters, Low Barrier Navigation Centers and
Transitional/Supportive Housing
Senate Bill 2 of 2007 strengthened planning requirements for emergency
shelters and transitional/supportive housing. The Development Code allows
emergency shelters by-right in the Light Industry (I) zone in compliance with
SB 2 and also allows transitional and supportive housing as a residential use
subject to the same standards as other residential uses of the same type in
the same zone.
In 2018 AB 2162 amended State law to require that supportive housing be a
use by-right in zones where multi-family and mixed uses are permitted,
including non-residential zones permitting multi-family uses, if the proposed
housing development meets specified criteria.

AB 101 (2019) added the requirement that low barrier navigation centers
meeting specified standards be allowed by-right in areas zoned for mixed
use and in non-residential zones permitting multi-family uses pursuant to
Government Code §65660 et seq.
The City is currently processing a Development Code amendment to allow
supportive housing and low barrier navigation centers consistent with State
law.
The City will also continue to work cooperatively with the Los Angeles
Homeless Services Authority and the San Gabriel Valley Council of
Governments in its efforts to develop a regional strategy for addressing
homelessness.
Eight-year objectives:
1. Continue to facilitate emergency shelters and transitional/
supportive housing, and continue participating with LAHSA and
SGVCOG on efforts to address homelessness throughout the
planning period.
2. Process an amendment to the Development Code in 2022 to
allow supportive housing and low barrier navigation centers
consistent with State law.
Responsible agency: Community Development Department
Timeline: Development Code amendment in 2022; support efforts to

Program H -12. Affordable Housing Incentives/Density Bonus
To facilitate the development of affordable housing, the City utilizes
Affordable Housing Incentives/Density Bonus Provisions (Development Code
Chapter 22.18). Incentives described in Chapter 22.18 apply to
developments of five or more dwelling units. If a density bonus and/or other
incentives cannot be accommodated on a parcel due to strict compliance
with the provisions of the Development Code, the Council may waive or
modify the development standards as necessary to accommodate bonus
units and other incentives to which the development is entitled. AB 2345 of
2020 revised State Density Bonus Law to increase incentives for affordable
housing. The City is currently processing an amendment to the Development
Code in conformance with AB 2345.
Eight-year objective: The City will amend the Development Code in
2021 consistent with current Density Bonus Law and continue to
encourage the production of affordable housing through the use of
density bonus and other incentives.

The City is committed to a streamlined development process and has
adopted procedures to facilitate efficient permit processing. Prospective
applicants are strongly encouraged to request a pre-application
conference with the Community Development Department before formal
submittal of an application. The purpose of this conference is to inform the
applicant of City requirements as they apply to the proposed development
project, review the procedures outlined in the Development Code, explore
possible alternatives or modifications, and identify necessary technical
studies or other supporting materials relating to the proposed development.
This process helps to minimize the time required for project review by
identifying issues early in the process before extensive engineering and
architectural design work has been done.
Consistent with new transparency laws, zoning, development standards and
fees will be posted on the City website.
Eight-year objective: The City will continue to offer the pre-application
conference and streamlined development processing, and periodically
review departmental processing procedures to ensure efficient project
processing. Zoning, development standards and fees will be posted on
the City website throughout the planning period.

Affirmatively Furthering Fair Housing and Equal Housing Opportunities
To adequately meet the housing needs
of all segments of the community, the
City promotes housing opportunities for
all persons regardless of race, religion,
gender, family size, marital status,
ancestry, national origin, color, age, or
physical disability.
Program H -14. Affirmatively Furthering Fair Housing
As a participating city in the Los Angeles County CDBG program, Diamond
Bar has access to the services of the Housing Rights Center for fair housing
outreach, education, and counseling on housing discrimination complaints.
The City will continue to advertise the fair housing program through
placement of fair housing service brochures at the public counter, at the
Senior Center, through the City's newsletter, and on the City website.
Apartment owners and managers are provided with current information
about fair housing issues, rights and responsibilities. The Apartment
Association of Greater Los Angeles conducts seminars on State, Federal and
local Fair Housing laws and compliance issues. In addition, the City will:
• Ensure that all development applications are considered, reviewed,

Appendix A
Evaluation of the Prior Housing Element
Section 65588(a) of the Government Code requires that jurisdictions evaluate the
effectiveness of the existing Housing Element, the appropriateness of goals,
objectives and policies, and the progress in implementing programs for the previous
planning period. This appendix summarizes the results of the City’s review of the
housing goals, policies, and programs of the previous Housing Element, and
evaluates the degree to which these programs have been implemented during the
previous planning period.
As discussed in Section 9.4-Constraints, the City adopted a new General Plan in
2019. As part of this Housing Element update, the goals and policies of the previous
Housing Element were reviewed for consistency with the new General Plan and
current State housing law, and Policy H-P-3.2 was updated to reflect the new
emphasis on mixed-use development in the General Plan Focus Areas.
All programs were also reviewed and updated to reflect current circumstances,
including the needs assessment and potential constraints, and the evaluation of
City progress in implementing prior programs.
Table A-1 summarizes the programs contained in the previous Housing Element
along with program objectives, timeframe and accomplishments.
Table A-2 presents the City’s progress toward the quantified objectives from the
previous Housing Element.

Residential Sites Inventory
The assumptions and methodology for the residential sites inventory are provided

Methodology for the Sites Inventory Analysis
The residential sites inventory is comprised of three components: 1) approved
projects; 2) underutilized (non-vacant) sites with potential for additional residential
development or redevelopment; and 3) potential accessory dwelling units (ADUs).
Potential sites for residential development during the 2021-2029 planning period are
summarized in Table B-1. As shown in this table, adequate capacity is available to
accommodate the City’s RHNA allocation in all income categories; however,
zoning amendments are required to reconcile development regulations with the
recently adopted General Plan (see Program H-8 in Section 9.5). Additional analysis
to support this finding is provided in the discussion below and in Tables B-2 through

Underutilized Sites
Underutilized sites with potential for additional residential development or
redevelopment are listed in Tables B-3 through B-5. These sites are within the
General Plan Focus Areas discussed below. Sites that allow residential or mixed-use
development at a density of at least 30 units/acre are considered suitable for all
income categories based on State default density, while sites allowing up to 20 units
per acre were assigned to the moderate or above-moderate income categories.
In the Focus Areas where mixed-use development is encouraged, development
intensity is regulated by floor area ratio as described in the following chart.
7.2.c

Focus Areas. As described in Section 9.4, Constraints, the City adopted a comprehensive
General Plan update10 in 2019. One of the key features of the new General Plan was the
establishment of several new Focus Areas where substantial land use changes are
planned as part of a strategy to provide walkable mixed-use activity centers. These
Focus Areas provide opportunities for infill development that can incorporate a range of
housing, employment, and recreational uses to meet the needs of families, young
people, senior citizens, and residents of all incomes. Three of these Focus Areas,
summarized below, are expected to facilitate the development of a significant portion
of the City’s RHNA allocation during the planning period. Development standards
include residential densities (housing units per acre) and floor area ratio (FAR), which is
the ratio of building floor area to lot area.
• The Town Center Focus Area, located along Diamond Bar Boulevard between
SR-60 and Golden Springs Drive, is intended to build on the success of recent
commercial redevelopment in that area. The Town Center is designated for
mixed-use development that would serve as a center of activity for residents
and provide housing, entertainment and retail opportunities and community
gathering spaces in a pleasant, walkable environment. The General Plan
establishes a maximum residential density of 20.0 dwelling units per acre and a
maximum FAR up to 1.5 for this Focus Area (Table B-3).
• The Neighborhood Mixed Use Focus Area is envisioned as a combination of
residential and ancillary neighborhood-serving retail and service uses to
promote revitalization of the segment of North Diamond Bar Boulevard between
the SR-60 interchange and Highland Valley Road. This neighborhood has
potential to benefit from its proximity to Mt. San Antonio College and Cal Poly
Pomona. This General Plan land use designation has an allowable residential
density of up to 30.0 dwelling units per acre and a maximum FAR of 1.25 (Table
B-4).
• The Transit-Oriented Mixed Use Focus Area leverages underutilized sites
adjacent to the Metrolink commuter rail station to provide for higher-density
housing, offices, and supporting commercial uses close to regional transit. This
area encourages new employment and housing development in a key location
that emphasizes multi-modal transportation options. This General Plan
designation allows residential development at a density of 20.0 to 30.0 dwelling
units per acre and a maximum FAR of 1.5 (Table B-5).
The 2040 General Plan provides the guiding framework for development in these Focus
Areas; however, zoning regulations have not yet been amended to reflect General Plan
policy for these areas. The City is currently in the process of updating the Development
Code to revise land use regulations for these Focus Areas consistent with the standards
established in the new General Plan within three years, pursuant to Government Code
§65583(c)(1)(A) (see Program H-8 in Section 9.5). The development assumptions reflected
in Tables B-3 through B-5 are based upon the new General Plan land use designations
rather than current zoning designations.
Realistic Capacity and Suitability of Non-Vacant Sites. Since the General Plan
designation for the Focus Areas is for mixed use, the capacity for new housing is

7.2.c
Packet Pg. 146
9-80 HOUSING ELEMENT 2021-2029 │ Diamond Bar General Plan 2040
estimated as 50% of the total allowable number of units on each parcel. In addition,
parcels smaller than 0.5 acre have been conservatively excluded from the potential unit
totals pursuant to Government Code §65583.2(c)(2)(A). Pursuant to Government Code
Sec. 65583.2(h), zoning for the sites listed in Tables B-3, B-4 and B-5 shall ensure that:
a) at least 50% of the shortfall of low- and very low-income regional housing need
can be accommodated on sites designated for exclusively residential uses; or
b) if accommodating more than 50% of the low- and very low-income regional
housing need on sites designated for mixed-uses, all sites designated for mixed-
uses must allow 100% residential use and require residential use to occupy at least
50% of the floor area in a mixed-use project.
The estimated yield of parcels in the Focus Areas is considered to be realistic due to the
significant development potential compared to existing development FAR. As seen in
Tables B-3 through B-5, the existing FAR for most properties is well below 0.5 and the
average FAR for all properties are as follows:
Town Center Mixed Use: 0.33 average FAR
Neighborhood Mixed Use: 0.09 average FAR
Transit-Oriented Mixed Use: 0.27 average FAR
The significant potential increase in development creates a strong economic investment
incentive for redevelopment, and as a result, the existing uses are likely to be
discontinued during the planning period.
Affirmatively Furthering Fair Housing. Sites for additional housing are located throughout
the community to affirmatively further fair housing. For example, the three new mixed-use
areas provide significant potential for housing in areas with good access to jobs,

Accessory dwelling units (ADUs) represent a significant opportunity for affordable
housing, particularly for single persons or small households including the elderly,
college students, young adults, and caregivers. Recent changes in State law have
made the construction of ADUs more feasible for homeowners, and the City has
seen an increase in ADU development applications recently.
Table B-6 shows ADU permit trends during 2018-2020 in Diamond Bar. The average
rate of ADU permits over this 3-year period is 5.3 units per year. At that rate, it is
estimated that approximately 42 additional ADUs will be permitted during the 2021-
2029 planning period. Based on recent analysis conducted by SCAG11 over two-
thirds of future ADUs are expected to be affordable to low- and moderate-income
households.

Public Participation Summary
Public participation is an important component of the planning process, and this
update to the Housing Element has provided residents and other interested
stakeholders numerous opportunities to provide comments and recommendations.
Early in the update process a Housing Element web page was created on the City
website12 and a Housing Element Frequently Asked Questions was prepared (Figure
C-1) and posted on the website. Public notice, agendas and materials for all
Housing Element meetings were posted on the website and at City Hall in advance
of each meeting and also sent by direct mail to housing advocates and non-profit
organizations representing the interests of lower-income persons and special needs
groups (see Table C-1). Notices of public hearings were also published in the local
newspaper.
For each public meeting the City offered reasonable accommodation for persons
with disabilities to assist them in participating in the meeting, including the provision
of transcription of meeting minutes for non-English speakers. Transcribed minutes
may be easily translated into other languages via free web applications such as
Translate.Google.com.
After receiving comments on the draft Housing Element from the State Housing and
Community Development Department, a proposed final Housing Element was
prepared and made available for public review prior to adoption by the City
Council.
The following is a list of opportunities for public involvement in the preparation of this
Housing Element update.

Summary of Public Comments and Responses
Comment Response
We have a housing crisis Yes, the State Legislature has declared there is a
housing crisis in California
The housing market is strongly influenced by
investors
Yes
Children who grew up in Diamond Bar have difficulty
finding affordable housing that enables them to
continue living here
One of the main purposes of the Housing Element is
to increase the availability of housing at all income
levels so that grown children can afford to remain in
the community.
The City should consider an inclusionary housing
program
“Inclusionary housing” refers to a requirement that a
portion of new housing is made available at
affordable rents or prices. There are valid arguments
for and against such policies, and each city must
evaluate whether inclusionary requirements are
appropriate.
Diamond Bar doesn’t have sufficient transportation
and parking infrastructure to handle the amount of
development assigned in the RHNA, such as streets
serving the Metrolink station
Transportation issues must be a part of future
planning and development decisions, along with the
analysis of housing needs and the appropriate
locations for new housing.
Future planning and development of the Focus
Areas needs to be done thoughtfully so that these
areas enhance the quality of life in Diamond Bar
Detailed planning for the Focus Areas will be done
based on the policy framework established in the
General Plan and site-specific analysis conducted
during the preparation of specific plans and
development regulations for these areas.
If a site is listed in the inventory, is it required to be
developed for affordable housing?
No, the sites inventory only describes where
additional housing could be built based on zoning
regulations. Property owners will decide if and when
development occurs. The City or the State cannot
force property owners to develop their property for
housing.

9-68
9-79
The element has been revised to include a description of public outreach, an
assessment of fair housing, identification and prioritization of contributing
factors to fair housing issues and goals, and actions sufficient to overcome
patterns of segregation and foster inclusive communities free from barriers
that restrict access to opportunity.
In addition, Program H-14 describes actions the City will take to affirmatively
further fair housing during the planning period.
B.2 Race and Ethnicity 9-7
9-52
The Needs Assessment (Table 9-4) includes data regarding the race and
ethnicity of Diamond Bar households. Additional data has been provided in
Figure 9-4.
B.3 Extremely-low-income
households
9-10/11 The Needs Assessment has been revised to provide additional data (Table 9-
11) and analysis regarding ELI households including tenure, and the analysis
provides additional information on potential housing problems and specific
housing needs of ELI households.
B.4 Sites Inventory Appendix B General Plan designation. The sites inventory (Tables B-3 through B-5) has
been revised to identify general plan designations.
Existing uses on non-vacant sites. The analysis of existing uses of non-vacant
sites in Tables B-3 through B-5 has been expanded to include the floor area
ratio (FAR) of existing buildings. FAR is an important indicator of
underutilization and market potential for redevelopment.
Electronic inventory. An electronic copy of the sites inventory will be
submitted to HCD with the adopted element.

Sites map. In addition to the citywide map (Figure B-1) the original draft
Housing Element included maps showing the locations of the sites within the
three Focus Areas (Figures B-2a, B-2b and B-2c).
Realistic Capacity. Appendix B has been revised to provide additional
analysis of the City’s methodology for calculating realistic capacity for sites
listed in the sites inventory. For sites zoned for nonresidential uses, the revised
element describes how the estimated number of residential units for each site
was determined.
Suitability of Nonvacant Sites. The analysis of nonvacant sites in the Town
Center, Neighborhood Mixed Use, and Transit-oriented Mixed-Use focus areas
has been expanded to demonstrate the potential for redevelopment,
including the extent existing uses constitute an impediment, recent
developments, development trends and market conditions. In addition, the
City Council resolution includes findings based on substantial evidence that
the existing use is not an impediment and will likely discontinue in the
planning period.
Second Units. The estimate of accessory dwelling unit (ADU) potential for the
planning period has been revised based on ADU permit trends during 2018-
2020.
B.5 Governmental Constraints 9-48 Infrastructure. The element has been revised to evaluate existing or planned
dry utilities supply capacity to accommodate the City’s regional housing
need for the planning period.
Water & Sewer Priority. The element has been revised to note that water and
sewer service providers must establish specific procedures to grant priority
water and sewer service to developments with units affordable to lower-
income households. The City has delivered the adopted housing element to
water and sewer service providers.

B.7 Special Housing Needs 9-20 Elderly. The original draft Housing Element included analysis of the housing
problems and needs of the elderly, including the following: “Many elderly
persons are dependent on fixed incomes or have disabilities. Elderly
homeowners may be physically unable to maintain their homes or cope with
living alone. The housing needs of this group can be addressed through
smaller units, accessory dwelling units on lots with existing homes, shared
living arrangements, congregate housing and housing assistance programs.”
Additional cross-references to City programs to address the needs of the
elderly has been provided.
9-16/17 Persons with disabilities. Additional analysis of potential housing problems and
unmet needs of persons with disabilities, as well as references to programs to
address those needs has been provided.

specific role in implementation; implementation timelines; objectives,
quantified where appropriate; and identification of responsible agencies and
officials. In addition, Programs H-1, H-2 and H-3 have been revised as follows:
Program H-1, Residential Neighborhood Improvement has been
revised to clarify if that the objective is for the 8-year planning period.
Program H-2, Home Improvement Program has been revised to
include the City’s specific role in administration and identify responsible
agencies and officials.

discretionary review or approval.
• Permit the development of at least 16 units per site.
• Require a minimum density of 20 units per acre; and
• Ensure a) at least 50 percent of the shortfall of low- and very low-income
regional housing need can be accommodated on sites designated for
exclusively residential uses, or b) if accommodating more than 50 percent of
the low- and very low-income regional housing need on sites designated for
mixed-uses, all sites designated for mixed-uses must allow 100 percent
residential use and require residential use to occupy at least 50 percent of

Addendum to the
Certified Final Program EIR
for the
City of Diamond Bar 2040 General Plan
October 2021
Overview
On December 17, 2019 the Diamond Bar City Council certified Final EIR No. SCH 2018051066
for the Diamond Bar 2040 General Plan. The City is now required to adopt an updated Housing
Element for the 2021-2029 planning period. The purpose of this Addendum is to demonstrate that
the 2021-2029 Housing Element update would not result in any of the conditions under which a
subsequent environmental document would be required pursuant to CEQA Guidelines Section
15164.
Purpose of an Addendum
CEQA Guidelines Section 15164(a) states: “The lead agency or responsible agency shall prepare
an addendum to a previously certified EIR if some changes or additions are necessary but none
of the conditions described in Section 15162 calling for preparation of a subsequent EIR have
occurred.”
The following analysis demonstrates that the 2021-2029 Housing Element update does not raise
any new environmental issues and requires only minor technical changes or additions to the
previous EIR to satisfy the requirements of CEQA for the proposed Housing Element update.
Public Review Process for an Addendum
CEQA Guidelines Section 15164(c) and 15164(d) state: “An addendum need not be circulated for
public review but can be included in or attached to the final EIR or adopted negative declaration.
The decision making body shall consider the addendum with the final EIR or adopted negative
declaration prior to making a decision on the project.”
Project Description: 2021-2029 Housing Element Update
State law requires every jurisdiction within the Southern California Association of Governments
(“SCAG”) region to prepare a Housing Element update for the 2021-2029 planning period.
Detailed requirements for Housing Elements are established in California Government Code Sec.
65580 et seq.
The Draft 2021-2029 Housing Element, which is posted on the City website at:
https://www.diamondbarca.gov/963/Housing-Element-Update, focuses on establishing City
policies and programs to address the housing needs of current and future Diamond Bar residents.
The Draft Housing Element includes the following sections:
• An introductory overview of the Housing Element (Section 9.1)
• Analysis of the City's demographic and housing characteristics and trends (Section 9.2)
• Evaluation of resources and opportunities available to address housing needs (Section 9.3)
7.2.e
Packet Pg. 190
Addendum to Final EIR No. SCH 2018051066
Diamond Bar 2021-2029 Housing Element
Page 2 of 4
• Analysis of potential governmental and non-governmental constraints to meeting the City's
housing needs (Section 9.4)
• The Housing Action Plan for the 2021-2029 planning period (Section 9.5)
• Review of the City’s accomplishments during the previous planning period (Appendix A)
• An inventory of sites that could accommodate the City’s new housing needs (Appendix B);
and
• A description of opportunities for stakeholders to participate in the preparation of the Housing
Element (Appendix C)
Generally, the most significant issues addressed in the Housing Element are: 1) whether City
plans and regulations accommodate housing for persons with special needs in compliance with
State law; and 2) how the City will accommodate its share of regional housing needs assigned
through the Regional Housing Needs Assessment (“RHNA”) process.
Housing for Persons with Special Needs. State law establishes specific requirements related
to City regulation of housing for persons with special needs, including the homeless and persons
with disabilities. Section 9.4 of the Housing Element (Constraints) contains an analysis of City
plans and regulations for a variety of housing types. The analysis concluded that while current
City regulations are consistent with most laws regarding special needs housing, some recently
adopted laws will require that the Municipal Code be amended in order to ensure consistency with
State law. Section 9.5 (Housing Action Plan) of the Housing Element includes the following
programs to comply with State requirements:
• Program H-10. Accessory Dwelling Units. State law has been amended several times over
the past few years to establish mandatory local standards and procedures intended to
encourage production of ADUs. This program includes a commitment to process a
Development Code amendment in conformance with current State law.
• Program H-11. Emergency Shelters, Low Barrier Navigation Centers and
Transitional/Supportive Housing. The Development Code establishes standards and
procedures for these types of housing targeted for persons who are homeless or at risk of
becoming homeless. This program includes a commitment to process a Development Code
amendment in conformance with recent changes to State law. These changes include
allowing supportive housing meeting specified criteria in zones where multi-family and mixed
uses are permitted, and allowing low barrier navigation centers meeting specified standards
in areas zoned for mixed use and in non-residential zones permitting multi-family uses. Low
barrier navigation centers are defined as “Housing first, low-barrier, service-enriched shelters
focused on moving people into permanent housing that provides temporary living facilities
while case managers connect individuals experiencing homelessness to income, public
benefits, health services, shelter, and housing.”
• Program H-12. Affordable Housing Incentives/Density Bonus. Density bonus refers to the
State law requiring cities to allow increased density and other incentives for housing
developments that include long-term commitments to provide units affordable to low- and
moderate-income households. Recent changes to State Density Bonus Law have increased
the required amount of density bonus and other incentives for affordable housing. This
program includes a commitment to amend the City’s density bonus regulations consistent with
current State law.
Regional Housing Needs Assessment. The Regional Housing Needs Assessment (“RHNA”) is
the process established in State law by which future housing needs are determined for each city.

On March 4, 2021 SCAG adopted the final RHNA Plan, which assigns Diamond Bar the following
housing needs.

Extremely Low +
Very Low Low Moderate Above
Moderate Total
844 434 437 806 2,521
Source: SCAG, 3/4/2021
The RHNA allocation identifies the amount of additional housing a jurisdiction would need in order
to have enough housing at all price levels to fully accommodate its assigned share of the region’s
housing need during the 8-year planning period. The RHNA is a planning requirement based upon
housing need, not a construction quota, mandate, or prediction of future housing development.
Jurisdictions are not required to build housing or issue permits to achieve their RHNA allocations.
The Housing Element must include an evaluation of potential capacity for additional housing
based on land use patterns, development regulations, other development constraints (such as
infrastructure availability and environmental conditions) and real estate market trends. The
analysis must be prepared at a parcel-specific level of detail and identify properties (or “sites”)
where additional housing could be built consistent with City regulations. This evaluation is referred
to as the “sites analysis” and State law requires the analysis to demonstrate that the city has
adequate sites with appropriate zoning to fully accommodate additional housing development
commensurate with its RHNA allocation in each income category. Appendix B of the Housing
Element includes a parcel-level analysis of sites that could accommodate the City’s RHNA
allocation.
Diamond Bar’s 2040 General Plan, adopted in December 2019, estimates that up to 3,750 new
housing units could be built in the city by 2040, depending on market conditions. It is expected
that much of this growth will occur within the Town Center Mixed Use, Neighborhood Mixed Use,
Transit Oriented Development and Community Core Overlay focus areas, while most existing
residential neighborhoods will experience less growth and change.
The 2040 General Plan provides the guiding framework for development in these Focus Areas;
however, zoning regulations have not yet been amended to reflect General Plan policy for these
areas. Revisions to the Development Code are proposed to conform regulations for the Focus
Areas to the policies established in the General Plan. Program H-8 in Section 9.5 of the Housing
Element describes actions the City will take to complete the required Code amendments
consistent with the 2040 General Plan and in compliance with State law.
Environmental Analysis and Conclusion
The 2040 General Plan EIR evaluated potential environmental impacts that would be expected to
occur as a result of future development consistent with the General Plan. Because the proposed
2021-2029 Housing Element assumes development consistent with General Plan land use
designations and policies, no new significant effects would occur that were not previously
analyzed in the General Plan EIR. The proposed Development Code amendments related to
affordable housing density bonus and housing for persons with special needs are required to
conform City regulations with current State law; therefore, these amendments would not change
the type or amount of development already allowed under State law.

Therefore, pursuant to California Environmental Quality Act (CEQA) Guidelines Section 15164,
an addendum is the appropriate CEQA document for the 2021-2029 Housing Element update.
There is no substantial evidence that the proposed Housing Element amendment will result in
significant environmental impacts not previously addressed in the 2040 General Plan EIR.
Consequently, no additional CEQA analysis is required.

Mayor Steve Tye
City of Diamond Bar
21810 Copley Drive
Diamond Bar, CA 91765
Dear Mayor Tye,
We are writing on behalf of Abundant Housing LA regarding Diamond Bar’s upcoming 6th
Cycle housing element update.Abundant Housing LA is a pro-housing education and advocacy
organization working to help solve Southern California’s housing crisis.We support efforts to
reform zoning codes and expand housing production,which are needed to reduce rents,
improve access to jobs and transit,strengthen the local economy and job market,and combat
segregation.We have a large and growing membership base throughout Los Angeles County,
including Diamond Bar.
California has a statewide housing shortage of nearly 3.5 million homes,and has the highest
poverty rate in the nation after accounting for housing costs.Households at all levels of income
face a historically high rent burden.Exclusionary zoning and longstanding constraints on denser
housing have led to an undersupply of medium and high density housing near jobs and transit.
This contributes to high rents and displacement of households.
Over the past few years,new state laws (e.g.AB 686 (2018),SB 166 (2017),AB 1397 (2017),
SB 828 (2018),SB 35 (2017),etc.)have strengthened the Regional Housing Needs
Assessment (RHNA),which sets a housing growth target for individual jurisdictions and requires
jurisdictions to update their housing elements in order to achieve these targets.
These changes to state law have led to historically high jurisdiction-level housing growth targets
in the upcoming 6th Cycle Housing Element Planning Cycle,and have empowered the state
Department of Housing and Community Development (HCD)to enforce appropriately high
standards for housing element updates.We are encouraged that Diamond Bar was given a
target of 2,513 new homes,of which 1,273 must be affordable to lower-income
households.
As jurisdictions start the housing element update process,AHLA seeks to provide guidance on
how jurisdictions should fulfill both the letter and the spirit of housing element law.Unfortunately,
some jurisdictions are already seeking to skirt their obligation to sufficiently plan to meet their
housing needs.AHLA will scrutinize jurisdictions’housing elements,submit comments to HCD
as needed,and collaborate closely with nonprofits that bring legal action against jurisdictions
that fail to comply with state housing laws.
1
7.2.f
Packet Pg. 194
Of course,AHLA recognizes that the COVID-19 pandemic and resulting economic devastation
have made it more difficult for jurisdictions to meet ambitious RHNA targets.But the pandemic
has made it even more critical than ever for jurisdictions to solve the region’s housing crisis and
encourage economic recovery.We seek to collaborate with you and your team on policy efforts
to achieve the RHNA goals.
To that end,we have published a memo,Requirements and Best Practices for Housing
Element Updates:The Site Inventory,explaining the key legal requirements,as well as HCD
and AHLA’s recommended best practices,for housing element updates.Additionally,this
checklist provides a summary of our core policy recommendations.We respectfully
encourage you to incorporate the concepts detailed in these documents into Diamond Bar’s
housing element update.
As your team begins to develop Diamond Bar’s housing element update,we would like to draw
particular attention to four critical components of the site inventory analysis:
1.Incorporating an estimate of the likelihood of development and the net new units if
developed of inventory sites
2.Using an HCD-recommended “safe harbor”methodology for forecasting future ADU
production
3.Prioritizing high-opportunity census tracts and well-resourced areas (e.g.near transit,
jobs,schools,parks,etc.)when selecting sites for lower-income housing opportunities,in
order to affirmatively further fair housing
4.Including the HCD-recommended buffer of at least 15-30%extra capacity in the site
inventory, in order to avoid violating the No Net Loss requirement
Component #1:Housing elements should estimate and report both the likelihood of
development and the net new units if developed of inventory sites.
Just because jurisdictions zone for more housing doesn’t mean that the housing will actually be
built.The economic cycle,uncertainty of market conditions,the current usage of nonvacant
sites,and land use regulations all influence the extent to which rezoned parcels are built to their
maximum theoretical capacity.
A parcel’s maximum theoretical capacity is not the same as its realistic capacity.To draw a
parallel to college admissions,when UCLA wants 2,000 students in its incoming class,they
admit 4,000 students.Similarly,to achieve housing production targets,jurisdictions must
increase zoned capacity well above the target number of new homes.
An accurate assessment of site capacity is necessary in order for the housing element to
achieve sufficient housing production.The site capacity estimate should account for the
following two factors:
2
7.2.f
Packet Pg. 195
●What is the likelihood that the site will be developed during the planning period?
●If the site were to be developed during the planning period,how many net new units of
housing are likely to be built on it?
These are the likelihood of development and net new units if developed factors,as 1 2
required by HCD guidelines.The portion of the jurisdiction’s RHNA target that a site will
realistically accommodate during the planning period is:
(likelihood of development) x (net new units if developed) = realistic capacity.
In past planning cycles,the likelihood of development factor was not expressly considered;
housing elements frequently assumed that most or all site inventory locations would be
redeveloped to their maximum theoretical capacity.Since this generally did not happen,
jurisdictions consistently fell short of their RHNA targets as a result.This is the case for
Diamond Bar,which is not on a path to achieving its 5th cycle RHNA targets for very low,low,
and moderate income housing.Through 2019,it has permitted 6 homes that are affordable at
these income levels, out of a total RHNA target of 680 homes.
5th Cycle RHNA Targets vs. Actual Housing Production (2014-19)
Income Bucket RHNA Target Homes Permitted
VLI 308 1
LI 182 5
MI 190 0
AMI 466 309
Total 1,146 315
According to Diamond Bar’s 5th cycle housing element,the city had theoretical capacity for
roughly 1,291 more housing units.Through 2019,Diamond Bar permitted 315 housing units , 3 4
which equates to 420 housing units permitted by the end of the 5th cycle (assuming that the
same annual permitting pace continues in 2020 and 2021).This implies that in Diamond Bar,
excess zoned capacity has a 33%likelihood of being developed (420 actual units divided by
1,291 theoretical units).
Diamond Bar’s 6th cycle housing element should incorporate this likelihood of development
estimate into its site inventory analysis.This would be consistent with HCD guidelines,while 5

also ensuring that enough zoned capacity is available to encourage 2,513 housing units to be
built by the end of the 6th cycle.Assuming that zoned capacity has a 33%likelihood of being
developed in the next 8 years,the housing element must allow for 7,615 units of zoned
capacity in order to achieve 2,513 actual housing units.If Planning believes that a higher
likelihood of development (and thus a smaller zoned capacity increase)is justified for certain
parcels in the site inventory, persuasive data to support this assumption must be provided. 6
Component #2:Housing element updates should use an HCD-recommended “safe harbor”
methodology for forecasting future ADU production.
Local jurisdictions frequently use overly optimistic estimates of future ADU production to avoid
necessary housing reform and rezoning.ADU development estimates must reflect actual
on-the-ground conditions to ensure that they are realistic.Overly aggressive ADU production
estimates set jurisdictions up for failure in providing the required housing for residents.
To that end,HCD has established two safe harbors for forecasting ADU production during the
6th Cycle .One option (“Option #1”)is to project forward the local trend in ADU construction 7
since January 2018.The other,for use when no other data is available (“Option #2”),assumes
ADU production at five times the local rate of production prior to 2018.Jurisdictions are also
permitted to include programs that aggressively promote and incentivize ADU construction.
Where no other data is available,jurisdictions may assume an average increase of five times
the previous planning period construction trends prior to 2018.Jurisdictions may also use
regional ADU production trends,and include programs that aggressively promote and
incentivize ADU construction.Jurisdictions should clearly and explicitly state their methodology
and data sources for future ADU development forecasts.
According to HCD,Diamond Bar issued permits for 2 ADUs in 2017,2 ADUs in 2018,and 6
ADUs in 2019.Under HCD’s “Option #1”,Diamond Bar could take the average of the 2018 and
2019 ADU production trends,and forecast that 4 ADUs will be permitted per year during the 6th
cycle. This would allow for a total 6th cycle forecast of 32 ADUs.
Under HCD’s “Option #2”,Diamond Bar could multiply the 2017 ADU production trend by five,
and forecast that 10 ADUs will be permitted per year during the 6th cycle.This would allow for a
total 6th cycle forecast of 80 ADUs.
Another,more aggressive,option would take the average of the 2018 and 2019 ADU production
trends,and multiply that average by five.This methodology would forecast that 20 ADUs will be
permitted per year during the 6th cycle.This would allow for a total 6th cycle forecast of 160
6 HCD Site Inventory Guidebook, pg. 20-21
7 HCD Site Inventory Guidebook, pg. 31

7.2.f
Packet Pg. 197
ADUs.Abundant Housing LA does not recommend this methodology,since it is not an
HCD-defined safe harbor forecasting option.
Diamond Bar should use HCD’s Option 1 or 2 safe harbor when projecting annual ADU
production.If it believes that higher ADU production forecasts are warranted,it must provide
well-grounded estimates,based on the pace of ADU production in neighboring jurisdictions,and
must explain programs or policy efforts that could lead to higher ADU production.
Finally,per HCD,the housing element “should also include a monitoring program that a)tracks
ADU and JADU creation and affordability levels,and b)commits to a review at the planning
cycle midpoint to evaluate if production estimates are being achieved.”Diamond Bar’s housing 8
element should commit to mid-cycle rezoning if ADU production is lower than forecasted,and its
midpoint review should be linked with immediate and automatic programs to increase housing
production in the second half of the RHNA cycle.AHLA’s recommended approach is to
incorporate by-right density bonuses on inventory sites,which would automatically take effect
mid-cycle if the ADU target is not met.The density bonus should be large enough,and apply to
enough parcels, to fully make up for any ADU production shortfall.
Component #3:Housing elements must prioritize high-opportunity census tracts and
well-resourced areas (e.g.near transit,jobs,schools,parks,etc.)when selecting sites for
lower-income housing opportunities, in order to affirmatively further fair housing.
AB 686 (2018)requires housing element updates to “affirmatively further fair housing”,which is
defined as “taking meaningful actions,in addition to combating discrimination,that overcome
patterns of segregation and fosters inclusive communities free from barriers that restrict access
to opportunity based on protected characteristics.”
Diamond Bar’s history details examples of how housing policy and land use regulations were
once used to exclude members of minority groups.Redlining and restrictive covenants,which
restricted where Black Americans could live,were once commonplace throughout Los Angeles
County.Thankfully,Diamond Bar is more welcoming today;18%of the city’s population is
Hispanic and 56%of the city’s population is Asian-American .However,exclusion continues on 9
the basis of income:the median home sale price in Diamond Bar was $660,000 in 2018 ,and 10
51%of the city’s renters are “rent-burdened”(i.e.they spend more than 30%of their income on
rent).High housing costs place a disproportionate burden on lower-income communities of 11
color, and have the effect of excluding them from the city altogether.

Packet Pg. 198
Jurisdictions must address this issue by accommodating the lower-income RHNA targets in a
way that conforms with AFFH requirements.HCD’s Site Inventory Guidebook offers
recommendations for how jurisdictions should accomplish this.HCD is likely to require
jurisdictions to distribute lower-income housing opportunities throughout the
jurisdiction,and recommends that jurisdictions first identify development potential for
lower-income housing in high-opportunity neighborhoods . 12
Given that single-family,exclusionary zoning predominates in many of Diamond Bar’s high-and
highest-opportunity census tracts (as defined in the TCAC/HCD Opportunity Map),rezoning is
required in order to accommodate the RHNA targets for lower-income households.Additionally,
focusing rezoning in single-family zoned areas will expand housing opportunities while
minimizing the impact on existing renters in multifamily-zoned areas.
In order to fairly distribute housing opportunities citywide,Diamond Bar should develop a
quantitative methodology for scoring neighborhoods,based on factors like housing costs,
median income,access to transit,access to jobs,access to schools,and environmental quality.
Neighborhoods that score higher on these dimensions should be allocated higher housing
growth targets,and rezoning should be based on these neighborhood-level housing growth
targets.
Finally,Diamond Bar should identify funding sources,public resources,and density bonus
programs to maximize the likelihood that housing projects with below market-rate units are
actually built.Local measures like a real estate transfer tax and congestion pricing could help
generate new funding to support affordable housing production and preservation.
Component #4:Housing elements should include the HCD-recommended buffer of at least
15-30%extra capacity in the site inventory,in order to avoid violating the No Net Loss
requirement.
SB 166 (2017)requires adequate sites to be maintained at all times throughout the planning
period to accommodate the remaining RHNA target by each income category.This means that 13
if a jurisdiction approves a development on a parcel listed in the site inventory that will have
fewer units (either in total or at a given income level)than the number of units (either in total or
at a given income level)anticipated in the site inventory,then the jurisdiction must identify and
make available enough sites to accommodate the remaining unmet RHNA target for each
income category. 14
If additional sites with adequate zoned capacity don’t exist,then the jurisdiction must rezone
enough sites to accommodate the remaining unmet RHNA target within 180 days.If the

13 HCD No Net Loss Law Memo, pg. 1
14 HCD Site Inventory Guidebook, pg. 22
6
7.2.f
Packet Pg. 199
jurisdiction fails to accomplish this rezoning in the required period,then the consequences will
include decertification of the housing element and potential state legal action.
To ensure that adequate housing capacity at all income levels exists in the housing element
through the 6th Cycle,HCD recommends that “the jurisdiction create a buffer in the housing
element inventory of at least 15-30%more capacity than required,especially for capacity to
accommodate the lower income RHNA.”Diamond Bar should “overshoot”on total site 15
capacity for each income level,in order to ensure that the City’s RHNA target is achieved
at all income levels.
The City of Diamond Bar has an obligation to sufficiently plan to meet current and future
residents’housing needs.The housing element update affords Diamond Bar,and the broader
Southern California region,the chance to take bold action on lowering housing costs,reducing
car dependency,strengthening the local economy,and guaranteeing access to opportunity for
Californians of all racial and ethnic backgrounds.We urge you and your colleagues to fully
embrace this opportunity to transform Diamond Bar for the better.
Finally,it is worth noting that state law imposes penalties on jurisdictions that fail to adopt a
compliant 6th cycle housing element update by October 15,2021.On that date,noncompliant
jurisdictions will forfeit the right to deny residential projects on the basis of local zoning,so long
as projects include at least a 20%set-aside for below market-rate units .Jurisdictions that want 16
to maintain local control over new development should therefore plan to adopt a compliant
housing element update on time.
We would be glad to engage with your office and with the Planning Department throughout the
housing element update process.We look forward to a productive and collaborative working
relationship with the City of Diamond Bar on this critical effort.Thank you for your
consideration.

Dear Ms. Lee:
NOPH Response to 2021-2019 Housing Element Update, Planning Case No. PL2021-004
The Los Angeles County Sanitation Districts (Districts) received the letter and plans for the subject project
forwarded by your office on January 19, 2021. The City of Diamond Bar is located within the jurisdictional
boundary of District No. 21. We offer the following comments regarding sewerage service:
1. The Districts own, operate, and maintain the large trunk sewers that form the backbone of the regional
wastewater conveyance system. Local collector and/or lateral sewer lines are the responsibility of the
jurisdiction in which they are located. As such, the Districts cannot comment on any deficiencies in the
sewerage system in the City of Diamond Bar (City) except to state that presently no deficiencies exist in
Districts’ facilities that serve the City. For information on deficiencies in the City sewerage system, please
contact the City Department of Public Works and/or the Los Angeles County Department of Public Works.
2. The wastewater generated by the City is treated at the San Jose Creek Water Reclamation Plant (WRP)
located adjacent to the City of Industry, which has a capacity of 100 mgd and currently processes an
average flow of 58.5 mgd. All biosolids and wastewater flows that exceed the capacity of the San Jose
Creek WRP are diverted to and treated at the Joint Water Pollution Control Plant in the City of Carson.
3. In order to estimate the volume of wastewater a project will generate, go to www.lacsd.org, under Services,
then Wastewater Program and Permits, select Will Serve Program, and scroll down to click on the Table 1,
Loadings for Each Class of Land Use link for a copy of the Districts’ average wastewater generation factors.
4. The Districts are empowered by the California Health and Safety Code to charge a fee to connect facilities
(directly or indirectly) to the Districts’ Sewerage System or to increase the strength or quantity of wastewater
discharged from connected facilities. This connection fee is a capital facilities fee that is used by the Districts
to upgrade or expand the Sewerage System. Payment of a connection fee may be required before a project
is permitted to discharge to the Districts’ Sewerage System. For more information and a copy of the
Connection Fee Information Sheet, go to www.lacsd.org, under Services, then Wastewater (Sewage) and
select Rates & Fees. In determining the impact to the Sewerage System and applicable connection fees, the
Districts will determine the user category (e.g. Condominium, Single Family home, etc.) that best represents
the actual or anticipated use of the parcel(s) or facilities on the parcel(s) in the development. For more
specific information regarding the connection fee application procedure and fees, the developer should
contact the Districts’ Wastewater Fee Public Counter at (562) 908-4288, extension 2727.

5. In order for the Districts to conform to the requirements of the Federal Clean Air Act (CAA), the capacities
of the Districts’ wastewater treatment facilities are based on the regional growth forecast adopted by the
Southern California Association of Governments (SCAG). Specific policies included in the development
of the SCAG regional growth forecast are incorporated into clean air plans, which are prepared by the South
Coast and Antelope Valley Air Quality Management Districts in order to improve air quality in the South
Coast and Mojave Desert Air Basins as mandated by the CCA. All expansions of Districts’ facilities must

2021-2029 Housing Element Update
Dear Chairman Rawlings, Vice Chair Gaxg, Commissioner Barlas, Commissioner Mok,
and Commissioner Wolfe,
On behalf of the Southwest Regional Council of Carpenters ("Commenter" or
"Southwest Carpenters"), my Office is submitting these comments on the City of
Diamond Bar's ("City" or "Lead Agency") October 13, 2021 Special Meeting of the
Planning Commission regarding the draft 2021-2029 update to the City's General Plan
Housing Element ("Draft HEU," or "Project").
The Southwest Carpenters is a labor union representing more than 50,000 union
carpenters in six states and has a strong interest in well ordered land use planning and
addressing the environmental impacts of development projects.
Individual members of the Southwest Carpenters live, work and recreate in the City
and surrounding communities and would be directly affected by the Project's
environmental impacts.

Moreover, Commenters requests that the Lead Agency provide notice for any and all
notices referring or related to the Project issued under the California Environmental
Quality Act ("CEQA"), Cal Public Resources Code ("PRC") 5 21000 et seg, and the
California Planning and Zoning Law (`Planning and Zoning Law"), Cal. Gov't

21167(and Government Code Section 65092 require agencies to mail such notices to
any person who has filed a written request for them with the clerk of the agency's
governing body.
The City should require housing projects developed pursuant to the final Housing
Element Update to provide additional community benefits such as requiring local hire
and use of a spilled and trained workforce to build such projects. The City should
require the use of workers who have graduated from a Joint Labor Management
apprenticeship training program approved by the State of California, or have at least as
many hours of on-d-le-job experience in the applicable craft which would be required
to graduate from such a state approved apprenticeship training program or who are
registered apprentices in an apprenticeship training program approved by the State of
California.
Community benefits such as local hire and skilled and trained workforce requirements
can also be helpful to reduce environmental impacts and improve the positive
economic impact of the Project. Local lire provisions requiring that a certain
percentage of workers reside within 10 miles or less of a project site can reduce the

length of vendor trips, reduce greenhouse gas emissions and providing localized
economic benefits. Local hire provisions requiring that a certain percentage of workers
reside within 10 miles or less of a project site can reduce the length of vendor trips,
reduce greenhouse gas emissions and providing localized economic benefits. As
environmental consultants Matt Hagemann and Paul E. Rosenfeld note:
[A]ny local lure requirement that results in a decreased worker trip length
from the default value has the potential to result in a reduction of
construction -related GHG emissions, though the significance of the
reduction would vary based on the location and urbanization level of the
project site.
March S. 2021 SWAPE Letter to Mitchell M. Tsai re Local Hire Requirements and
Considerations for Greenhouse Gas Modeling.
Skilled and trained workforce requirements promote the development of skilled trades
that yield sustainable economic development. As the California Workforce
Development Board and the UC Berkeley Center for Labor Research and Education
concluded:
... labor should be considered an investment rather than a cost — and
investments in growing, diversifying, and upskilling California's workforce
can positively affect returns on climate mitigation efforts. In other words,
well trained workers are key to delivering emissions reductions and
moving California closer to its climate targets.'
Local skilled and trained workforce requirements and policies have significant
environmental benefits since they improve an area's jobs -housing balance, decreasing
the amount of and length of job commutes and their associated greenhouse gas
emissions. Recently, on May 7, 2021, the South Coast Air Quality Management District
found that that the "[u]se of a local state -certified apprenticeship program or a spilled
and trained workforce with a local hire component" can result in air pollutant
reductions.2

Cities are increasingly adopting local skilled and trained workforce policies and
requirements into general plans and municipal codes. For example, the City of Hayward
2040 General Plan requires the City to "promote local hiring ... to help achieve a more
positive jobs -housing balance, and reduce regional commuting, gas consumption, and
greenhouse gas emissions.`
In fact, the City of Hayward has gone as far as to adopt a Skilled Labor Force policy
into its Downtown Specific Plan and municipal code, requiring developments in its
Downtown area to requiring that the City "[c]ontribute to the stabilization of regional
construction markets by spurring applicants of housing and nonresidential
developments to require contractors to utilize apprentices from state -approved, joint
labor-management training programs, ...` In addition, the City of Hayward requires
all projects 30,000 square feet or larger to "utilize apprentices from state -approved,
joint labor-management training programs."5
Locating jobs closer to residential areas can have significant environmental benefits. As
the California Planning Roundtable noted in 2008:
People who live and work in the same jurisdiction would be more likely
to take transit, walk, or bicycle to work than residents of less balanced
communities and their vehicle trips would be shorter. Benefits would
include potential reductions in both vehicle miles traveled and vehicle
hours traveled.'
In addition, local lure mandates as well as skill training are critical facets of a strategy to
reduce vehicle miles traveled. As planning experts Robert Cervero and Michael Duncan
noted, simply placing jobs near housing stock is insufficient to achieve VNIT reductions
since the skill requirements of available local jobs must be matched to those held by
local residents.' Some municipalities have tied local hire and skilled and trained

workforce policies to local development permits to address transportation issues. As
Cervero and Duncan note:
In nearly built -out Berkeley, CA, the approach to balancing jobs and
housing is to create local jobs rather than to develop new housing." The
city's First Source program encourages businesses to hire local residents,
especially for entry- and intermediate -level jobs, and sponsors vocational
training to ensure residents are employment -ready. While the program is
voluntary, some 300 businesses have used it to date, placing more than
3,000 city residents in local jobs since it was launched in 1986. When
needed, these carrots are matched by sticks, since the city is not shy about
negotiating corporate participation in First Source as a condition of
approval for development permits.
The City should consider requiring the utilization of skilled and trained workforce
policies and requirements to benefit the local area economically and mitigate
greenhouse gas, air quality and transportation impacts.

Subject: Local Hire Requirements and Considerations for Greenhouse Gas Modeling
Dear Mr. Tsai,
Soil Water Air Protection Enterprise ("SWAPE") is pleased to provide the following draft technical report
explaining the significance of worker trips required for construction of land use development projects with
respect to the estimation of greenhouse gas ("GHG") emissions. The report will also discuss the potential for
local hire requirements to reduce the length of worker trips, and consequently, reduced or mitigate the
potential GHG impacts.
V4,caz1{et T tips and �z•eerzktatzse has Calczllations
The California Emissions Estimator Model ("CaIEEMod") is a "statewide land use emissions computer model
designed to provide a uniform platform for government agencies, land use planners, and environmental
professionals to quantify potential criteria pollutant and greenhouse gas (GHG) emissions associated with both
construction and operations from a variety of land use projects.."1 CaIEEMod quantifies construction -related
emissions associated with land use projects resulting from off -road construction equipment; on -road mobile
equipment associated with workers, vendors, and hauling; fugitive dust associated with grading, demolition,
truck loading, and on -road vehicles traveling along paved and unpaved roads; and architectural coating
activities; and paving.'
The number, length, and vehicle class of worker trips are utilized by CaIEEMod to calculate emissions associated
with the on -road vehicle trips required to transport workers to and from the Project site during construction.3

Specifically, the number and length of vehicle trips is utilized to estimate the vehicle miles travelled ("VMT")
associated with construction. Then, utilizing vehicle -class specific EMFAC 2014 emission factors, CaIEEMod
calculates the vehicle exhaust, evaporative, and dust emissions resulting from construction -related VMT,
including personal vehicles for worker commuting'
Specifically, in order to calculate VMT, CalEEMod multiplies the average daily trip rate by the average overall trip
length (see excerpt below):
"VMTd = E(Average Daily Trip Rate ; *Average Overall Trip Length ;) n
Where:
n = Number of land uses being modeled."s
Furthermore, to calculate the on road emissions associated with worker trips, CaIEEMod utilizes the following
equation (see excerpt below):
"EmissionsP"u�ta"t =VMT * EF�„�,,;„g,Pon"ca"�
Where:
EmissionsP"n"ca�� =emissions from vehicle running for each pollutant
VMT =vehicle miles traveled
EF,""omg,Pon"cam =emission factor for running emissions."6
Thus, there is a direct relationship between trip length and VMT, as well as a direct relationship between VMT
and vehicle running emissions. In other words, when the trip length is increased, the VMT and vehicle running
emissions increase as a result. Thus, vehicle running emissions can be reduced by decreasing the average overall
trip length, by way of a local hire requirement or otherwise.

As previously discussed, the number, length, and vehicle class of worker trips are utilized by CalEEMod to
calculate emissions associated with the on -road vehicle trips required to transport workers to and from the
Project site during construction.' In order to understand how local hire requirements and associated worker trip
length reductions impact GHG emissions calculations, it is important to consider the CalEEMod default worker
trip parameters. CaIEEMod provides recommended default values based on site -specific information, such as
land use type, meteorological data, total lot acreage, project type and typical equipment associated with project
type. If more specific project information is known, the user can change the default values and input project -
specific values, but the California Environmental Quality Act ("CEQA") requires that such changes be justified by
substantial evidences The default number of construction -related worker trips is calculated by multiplying the

number of pieces of equipment for all phases by 1.25, with the exception of worker trips required for the
building construction and architectural coating phases,' Furthermore, the worker trip vehicle class is a 50/25/25
percent mix of light duty autos, light duty truck class 1 and light duty truck class 2, respectively."10 Finally, the
default worker trip length is consistent with the length of the operational home -to -work vehicle trips." The
operational home -to -work vehicle trip lengths are:
"(Bjased on the location and urbanization selected on the project characteristic screen. These values
were supplied by the air districts or use a default average for the state. Each district (or county) also
assigns trip lengths for urban and rural settings" (emphasis added).12
Thus, the default worker trip length is based on the location and urbanization level selected by the User when
modeling emissions. The below table shows the CaIEEMod default rural and urban worker trip lengths by air
basin (see excerpt below and Attachment A)."

As demonstrated above, default rural worker trip lengths for air basins in California vary from 10.8- to 19.8-
miles, with an average of 16.47 miles. Furthermore, default urban worker trip lengths vary from 10.8- to 14.7-
miles, with an average of 11,17 miles. Thus, while default worker trip lengths vary by location, default urban
worker trip lengths tend to be shorter in length. Based on these trends evident in the CalEEMod default worker
trip lengths, we can reasonably assume that the efficacy of a local hire requirement is especially dependent
upon the urbanization of the project site, as well as the project location.

To provide an example of the potential impact of a local hire provision on construction -related GHG emissions,
we estimated the significance of a local hire provision for the Village South Specific Plan ("Project") located in
the City of Claremont ("City"), The Project proposed to construct 1,000 residential units, 100,000-SF of retail
space, 45,000-SF of office space, as well as a 50-room hotel, on the 24-acre site. The Project location is classified
as Urban and lies within the Los Angeles -South Coast County. As a result, the Project has a default worker trip
length of 14.7 miles.' In an effort to evaluate the potential for a local hire provision to reduce the Project's
construction -related GHG emissions, we prepared an updated model, reducing all worker trip lengths to 10
miles (see Attachment B). Our analysis estimates that if a local hire provision with a 10-mile radius were to be
implemented, the GHG emissions associated with Project construction would decrease by approximately 17%

As demonstrated above, by implementing a local hire provision requiring 10 mile worker trip lengths, the Project
could reduce potential GHG emissions associated with construction worker trips. More broadly, any local hire
requirement that results in a decreased worker trip length from the default value has the potential to result in a
reduction of construction -related GHG emissions, though the significance of the reduction would vary based on
the location and urbanization level of the project site.
This serves as an example of the potential impacts of local hire requirements on estimated project -level GHG
emissions, though it does not indicate that local hire requirements would result in reduced construction -related
GHG emission for all projects. As previously described, the significance of a local hire requirement depends on
the worker trip length enforced and the default worker trip length for the project's urbanization level and
location.

Professional Experience
Dr, Rosenfeld has over 25 years' experience conducting environmental investigations and risk assessments for
evaluating impacts to human health, property, and ecological receptors. His expertise focuses on the fate and
transport of envirommental contaminants, human health risk, exposure assessment, and ecological restoration. Dr,
Rosenfeld has evaluated and modeled emissions from unconventional oil drilling operations, oil spills, landfills,
boilers and incinerators, process stacks, storage tanks, confined animal feeding operations, and many other industrial
and agricultural sources. His project experience ranges from monitoring and modeling of pollution sources to
evaluating impacts of pollution on workers at industrial facilities and residents in surrounding communities.
Dr. Rosenfeld has investigated and designed remediation programs and risk assessments for contaminated sites
containing lead, heavy metals, mold, bacteria, particulate matter, petroleum hydrocarbons, chlorinated solvents,
pesticides, radioactive waste, dioxins and furans, semi- and volatile organic compounds, PCBs, PAHs, perchlorate,
asbestos, per- and poly-fluoroalkyl substances (PFOA/PFOS), unusual polymers, fuel oxygenates (MTBE), among
other pollutants. Dr, Rosenfeld also has experience evaluating greenhouse gas emissions from various projects and is
an expert on the assessment of odors from industrial and agricultural sites, as well as the evaluation of odor nuisance
impacts and technologies for abatement of odorous emissions. As a principal scientist at SWAPE, Dr. Rosenfeld
directs air dispersion modeling and exposure assessments. He has served as an expert witness and testified about
pollution sources causing nuisance and/or personal injury at dozens of sites and has testified as an expert witness on
more than ten cases involving exposure to air contaminants from industrial sources.
