a Happy Thanksgiving.
10. INFORMATIONAL ITEMS : DCM/DeStefano asked if the Planning Commissioners '
would like to have a joint meeting with the City Council to discuss matters of interest. If so,
staff would begin working toward a specific date and time early next year.
Chair/Ruzicka asked that this matter be addressed again during the December 10 meeting to
see if there is interest.
DCM/DeStefano reported that last Thursday evening A1 Anz and the Walnut Valley Trailer
Park developers held a neighborhood meeting. The team of engineers and developers were
adequately repreBented. Approximately 24 community members including Louis Marcellin,
owner of the Walnut Valley Trailer Park were present. Questions and concerns from the
residents included traffic, noise, light and visual intrusion, delivery trucks, type of clientele
the hotel seeks, length of stay, prices, etc. Some residents were concemed about
development in general and wishing to have nothing occur at the site. They were also
!��; � . �`
NOVEMBER 26, 2002 Page 4 PLANNING COMMISSION
concerned about shopping center development to the west of Diamond Bar in the
unincorporated areas. There were also ques[ions raised about transpDrtation projects
occurring in the ensuing yeazs, cut-thro�gh traffic, truckers in residential neighborhoods, and
truckers illegally parked with refrigeration running. Staff took some of these matters to the
Sheriff' s Department and requested enforcement. This was simply an informational meeting
and no conclusions were reached.
VC/Tye said he felt the Extended Stay America personnel did an excellent job in presenting
their project and addressing issues of concern to the adjacent residents. He was not very
impressed with the balance of the presentation that he felt was almost confrontational. He
� thought the developer and engineer could have done a better job. The residents feel it is a
done deal. IYe believed the residents should be made aware that this project has not yet been
approved and that it is still under consideration for the type of improvements that wouid be
allowed on site.
C/Nelson agreed with VClTye and DCM/DeStefano. One particulaz issue came up early and
often during the meeting to wit, why was a block wall not proposed at the back of [he
property. In the beginning the engineer and architect gave reasons why it could not be done
and then on towazd the end of the meeting, they stated they heard the residents ]oud and clear
and seemed willing to compromise. He would look for a good reason why a wall could not
be built at the back of the property. He believed the proposed project could be improved
over what was proposed and he believed that was what the community expected.
DCM/DeStefano explained that since this was a developer' s meeting, staff was there only to
observe and answer some questions about the pxocess and opportunity for further
participation.
C/Nolan asked if there were any favorabie comments about the City listening to the residents.
VC/T'ye said he did not get the impression that their concems were being addressed. He got
the impression that the residents felt that the truckers were disturbing their neighborhood and
everyone knows that they are not supposed to be disturbing their neighborhood, but they sull
are disturbing the neighborhood.
DCMlDeStefano said he got the same impression . As a result, he went immediately to the
Sheriff' s Department and addressed the issue of the truckers parking illegally. He found out
Thursday night that a couple of tickets had been issued. The problem still exists with
SYSCO trucks and out of state truckers parking in the area to avail themselves of services.
Today during a Sheriff' s Department quarterly luncheon he brought this matter to their
attention. He believed that as a result of the conversations today, there would be some
renewed attention to the azea. The problem with out of state truckers is that they ignore the
tickets and go on their way.

MEMORANDUM
MEETING DATE : December 10 , 2002 '
TO : Chairman and Planning Commission
FROM : James DeStefano , Deputy City Manager
SUBJECT : General Plan Amendment 2002-01 , Zone Change 2002 -01 ,
Specific Plan 2002-01 , Development Review 2002 -07,
Conditional Use Permit 2002-05, Tentative Parcel Map Na

Declaration No. 2002 -07
BACKGROUND/ANALYSIS :
The project proposai is a continued public hearing from the October 22 , 2002 Pianning
Commission meeting . The requested discretionary approvals are required for the
proposed construction of a retail/commercial shopping center consisting of a 116-room
three-story hotel , two freestanding restaurants , and two office/retaii building pads
totaling approximately 70 ,370 gross square feet of building area on an approximate
6 . 50-acre site .
During the public hearing, a number of issues were raised by residents of the area . After
receiving public testimony and discussing many of the concerns , the Pianning
Commission directed the applicant to conduct a public outreach meeting . Staff was
directed to analyze "quality of life" issues and their potential effects on the surrounding
neighborhood . The issues included the following :
• Increased noise levels ; '
• Traffic;
• Safety;
■ Odors ;
� Privacy;
• Light and glare ;
■ Aesthetics
■ Truck parking on Brea Canyon Road , Lycoming Street and other adjacent
residential streets ; �
Additionally, the Planning Commission directed staff to identify the perceived benefits to
be derived from a commerciai development at this location , and conversely the potential
negative impacts . Also , a land use comparison chart was to be provided to examine the
probable uses under severai zoning classifications .
The applicant held a community meeting at the 21865 E . Copley Drive , Diamond Bar,
CA (South Coast Air Quality Management District) on Thursday, November 21 , 2002 at
7 :00 pm . Approximately 24 residents attended . The folfowing is a brief synopsis of the
aforementioned concerns and the applicanYs proposed mitigation measures .
Concern A licant's Pro osed Miti ation
Increased noise levels The proposed hotel location will act as a sound
The new commercial development wiii increase the barrier butfering some of the noise cursently
existing noise level, thus negatively impacting the generated by the freeway. Additionally, the new
quafity of life of the neighboring residentiaf landscaping along the perimeter of the site wiil aid
properties. in reducing noise generated by the new
development.
° Traffic impacts and aongestion Any development nn the site will have a �egative
The site has a single point of ingress and egress, impact on the adjacent roadways. However, after
and any new deve4opment wili create additiona{ conferring with the City's Traffic Engineer, the
traffic creating congestion problems on Brea proposed mitigation measures (i.e. deceleration
Canyon Road and many other surrounding lanes , median island with dedicated turn pockets
adjoining streets . and signal improvements, etc) wili help to minimize
the impacts . Also, based on the type of retail mix,
there will be a diffusion of peak time trips impacting
the adjacent roadways. A copy of the 7ra�c Study
is attached .
Safety A six-foot high fence is proposed around the site or
the affected residentiai property.
Odors Odo� diffusers will be applied to the venting system
There is a potential of cooking smelis from the of the restaurant tenants to limit the amount of food
proposed restaurant uses . odors.
Privacy The building is proposed in a location that provides
The guest rooms of the upper floor of the hotel may the greatest setback distance from the neighboring
invade the privacy of the adjacent reside�tial units . residential properties. Also, fencing and mature
trees are proposed along the north property line to
Eurther buffer and screen the windows of the third
floor rooms .
Light and glare The light standards will be designed so that all light
The development will create new light and glare will be directed down at a 90- degree angle and/or
that could spill onto the neighboring properties . affixed with shields to prevent the spill of light onto
adjacent properties. Additfonally, the photometric
. . diagram indicates that the new light should not
impact the adjacent residences. Also, signs will not
be located on buiiding wall facing the residentiai
ro erties .
Page 2 of 4
Aesthetics (View) The hotei has been located in the least obtrusive
The proposed hotel will block the existing views location . However, when the Cal Trans freeway
improvements are completed , the hotei will partially .
block this massive structure . Additionally, the
design of the hotel coupled with the mature trees
along the north and south sides of the site should
present an aestheticaily pleasing view:
Truck parking on Brea Canyon Road, Lycoming The City has recently red curbed 100 lineal feet
Street and other adjacent residential streets along the west side of Brea Canyon Road , and
posted "no stopping" signs . The City also heid a
meeting with the Sheriff's Department
representatives and informed them of the illegal
parking situation , which they are now monitoring . ,
In regards to the_ financial implications of the proposed development as it relates to
benefiting the City, staff is of the opinion that the requested land use and zone change
to allow the intended development is an appropriate alternative and logical evolution of
land use based on the established development pattern . The site size and configuration ,
direct access to a major arterial , and proximity to the freeway make it viable and
suitable for this type of retail/commercial development. Furthermore, staff believes that
a retail/commercial shopping center of this scale, intensity and diversity of uses will
assist in advancing the goals of the General Plan by:
■ Achieving economic stability through development and increased employment
opportunities ; and
■ Augmenting the City's revenue base (project is estimated to generate
approximately $230 ,000 in sales and transient occupancy taxes) to better '
support public services and facilities ; and
• Maximizing economic development potentiai of a underdeveloped freeway
oriented property;and
� Availability of goods and services for freeway, business or residential customers ; '
and
• Enhancing the City's image as a viable area for development; and
■ Encouraging new and expanded developments to locate in the City of Diamond
Bar.
Negative impacts could be seen as :
■ Added traffic to an existing burdened major arterial (Brea Canyon Road );
• Increased noise ;
Page 3 of 4
• Potentiai light and glare issues ;
■ Issues of privacy;
■ Concerns regarding security;
• Unsubstantiated impacts on neighboring residential property values .
Lastly, attached is a land use comparison chart (Exhibit "A") that identifies the possible
uses under several zoning classifications and the land uses proposed in the Specific
Plan . As shown , the Specific Plan severely limits the permitted uses to those that are
primarily retail sales tax producers .
� It is staff's opinion that an "office" land use designation would be more burdensome on
the existing roadway during peak periods, which has the potential to have a more direct
negative impact on the residential neighborhoods. Also, a "manufacturing or industrial"
land use designation could severely increase noise , odors and produce additional
unwanted truck traffic.
For reference we have attached a copy of the project proposal and requested
entitlements as more particularly described in the staff report dated October 22, 2002
prepared for the previous Planning Commission meeting .
RECOMMENDATION :
Staff recommends that the Planning Commission receive a report from staff, open the
public hearing , receive testimony, ciose the public hearing and after consideration of the
evidence presented in connection with the project proposal , direct staff to prepare
resolutions of approval with conditions , as appropriate for consideration at the next
regularly scheduled meeting .

Southbound traffic at a stand still through Lycoming intersection even during a red light.
The only possibility of a left turn during the current green is if someone lets you through.
Even the cars turning onto Brea Cyn from Lycoming cannot make the turn something
even through the next signai. A dedicated signal wouid help, however with the current
traffic the intersection is not left open. What happens with all the new traffic from the
center?

APPLICATION REQUEST: A request for approval of the following :
0 Genera{ Plan Amendment (Professiona{ Office to
General Commercial );
���-� �� 0 Zone Change (M- 1 -DP- BE to G2-SP), 5pecific
� �°�" } � � ��� P{an (to guarantee a comprehensive deve{opment

; 0 Development Review (location , design, site plan

The requested discretionary approvals are �equired
for the proposed construction of a retail/commercial
shopping center consisting of a 116-room three-
story hotel , two freestanding �estaurants , and two
office/retail building pads totaling to approximately
70, 370 gross square feet of building area .
PROJECT LOCATION : 850 Brea Canyon Road (APN 8719-013-010)
PROPERTY OWNER : Louis Marcellin
20326 Fuerte Drive
Walnut , CA 91789

APPLICANT : Phil W ilfiams (Extended Stay America )
2525 Cherry Avenue , �310
Signal Hill , CA 90806
EXEGUTIVE SUMMARY:
Approval of the requests would permit the applicant (Phii Wiiliams for Extended Stay
- America) to develop the site as a retail/commercia( shopping center consisting of a 116-
room three-story hotel , two freestanding restaurants, and t:vo office/retail buiiding pads
totaling approximately 70 , 370 square feet of gross building area . Additionally, the
development would contain a 60-foot high double-faced freestaading pylon sign (88Q
sq . ft. of total sign face area), with advertisement space for all proposed tenants .
Furthermore, granting approval would permit the commercial condominium subdivision
of the single 6 .50 gross acre site into five parcels ranging in size from .72 acres to 2 .44
acres.
The subject site currently has a General Plan land use designation of Professionai
Office and is zoned M- 1 -DP-BE (Light Manufacturing , Development F'lan-Billboard ,
Exclusion ). This zoning ciassification permits various light industriai/manufacturing uses
including research and development, and office-based industriat uses . The site is
currently deveioped and operated as a recreational vehicle (RV) storage park.
The requested development is not permitted under the existing land use designation
and implementing zoning classification . However, it is staff's opinion that the requested
land use and zone change to allow the intended development is an appropriate
alternative and logical evolution of land use based on the established development
pattern consisting of a mixture of complimentary commercial and residential uses .
Additionally, the site size and configuration , direct accc:ss to a major arterial , and
proximity to the freeway make it viable and suitabie for this type of retait/commercial
development. Furthermore, staff believes that a retaii/commercial shopping center of
this scale , intensity and diversity of uses will assist in advancing the goals of the
Genera4 Plan by:
o Achieving economic stability through development and increased employment
opportunities; and
o Augmenting the City's revenue base to better support public services and
facilities ; and
o Maximizing economic development potential of underdeveloped properties ; and
o Enhancing the City' s image as a viable area for development; and
o Encouraging new and expanded developmeats to locate in the City of Diamond
Bar.
2
To e nsure t hat t hese a forementioned g oals a re a chieved , staff is recommending the
adoption of a Specific Plan . The Specific Plan will provide regulatory controls that
assure development projects attain the desired level of quality and coherent compatibie '
community design . It establishes development standards (e.g. setbacks, landscaping ,
sign criteria , subdivision , etc), design guidelines , and public improvement requirements.
SEQUENCE OF ENTITLEMENT PROCESSING :
_ As previously stated , based on the proposed use and design , the proposed project
requires approval of the following seven (7) discretionary a;iplications :
1 . General Plan Amendment - Amendment to the General Plan Land Use Element
from Professional Office to General Commercial ;
2 . Zone Chanqe - Change of zone from M- 1 -DP-BE (Light Manufacturing-
Development Plan-Billboard Exclusion ) to G2 (Community Commercial-Specific
Plan) ;

Plan and approval of the Tentative Map is decided at a duly noticed public hearing
before the City Council based in patt upon a recomrr,sndation from the Planning
Commission . The Planning Commission makes a recommendation to the City Councii
as whether to approve or deny the request. The City Council is the final decision-making
body ior these applications.
Note: State !aw requires that the underlying Genera! Plan /and use designation and
- implemenfing zoning be consistent. Therefore, if the land use designation is
changed, the zone shali be revised to reflect the amendment.
The Planning Commissio�'s decision on the Devetopment Review, Condit'sonal Use
Permit, and Tree Permit wili be final, unless appealed to the City Council. However, if
approved by the Commission , the Development Review, Conditio�ai Use Permit, and
Tree Permit wfl! not be valid unless the General P4an Amendment, Zone Change,
Specific Plan and Tentative Map are approved by the City Councii.
ANALYSIS:
The seven (7) entitlements are sequential in nature, and are discussed as follows:
1 . General Plan Amendment - Amendment to the General Ptan Land Use Element
from Professional Office to General Commercial . �
The City's General Plan is a long-range planning document developed as a
comprehensive growth-management a nd c ommunity d evelopment s trategy. i t d efines
citywide po{icies that wiil be achieved through subsequent community pians ,
ordinances, standards and guidelines, studies , capital improvements , economic
development procedures and other pertinent programs. The adopted policies of the
General Plan guide the physical development pattern and promote the necessity of
adequate public services and facilities .
The General P1an is the under4ying controiling document. The preparation , adoption ,
implementation and maintenance of the General Plan aids in informing developers ,
citizens , decision-makers , other cities and counties of the rules that wili guide
development , and provide a basis fos local government judgments. Ail land use
decisions of the City of Diamond Bar should have a direct correlation to the established
goals and policies of the General Plan . Thereby, all future �and use decisions shouid be
iair and impartial . Most importantly, the Generaf Plan is to act as ihe constitution for
development, the foundation upon which all land use decisions are based .
The land Use Element is to establish a pattern for compatible land uses to reflect
existing conditions and to guide future development. By law, the element must set clear
standards for the density of population and the intensity of, development for each
proposed land use category.
The existing land use designation is Professional Office , which ailows for a variety of
generai , professionaf , and administrative offices , and simifar refated compatible uses.
a
The proposed land use designation is Generai Commercial , which provides for a wide
range of retail shopping and services uses. Adjacent land use designations within the
City of Diamond Bar are Genera{ Commercial (C), Industria{ Q } and Low Medium
Residential (RLM) as shown on the City of Diamond Bar land use map. Staff believes
that the proposed amendment represents a Iogicai, appropriate and rationale alternate '
{and use designation .
7he Planning Commission should weigh all evidence and recommend approval or
deniai ot the General Plan Amendment based on the goals and objectives of the
community as summarized in the Generai Plan. The Planning Commission 's
recommendation will be forwarded to the City Councii for a final decislon.
2 . Zone Change - Change of zone from M- 1 -DP-BE (Light Manufacturing-
Development Plan-Biliboard Exclusion) to C-2 (Community Commerciai-Specific Pian ) .
Fundamentally, in its original and primary sense, zoning is simply the division of a city '
into districts and the prescription and appiication of different regulations in each district.
These zoning regulations are generally divided into 1wo ctasses: ( 1 ) those which
regulate the height or bulk of buildings within certain designated districts — in other
words , those regula.tions which have to do with structural and architectural design of the
buiidings, and (2 ) those which prescribe ihe use to which buiidings within certain
designated districts may be put. The purposes of zoning is the attainment of unity in the
construction and development of a city, along lines of reasonable regulations which tend
to promote the heaith , safety and generaf welfare of the community.
The existing zoning of the property is M- 1 -DP (Light Manufacturing , Development Plan-
BiNboard Excfusion), which is intended to permit various light industriaUmanufacturing
uses including research and development, and office-based industrial uses . The request
is to change the zone to C-2-SP (Community Commercial-Development Plan), which
has been estabfisfied to provide areas for the location and operation of a wide range of
retail shopping and service uses. It is staff's opinion that tlie C-2 zone is an appropriate
implementing zone for the General Commercial land use designation . However, other
implementing zoning designations could be C-1 or G3 , each having various
development intensities and permitted uses .
The Planning Commission should weigh all evidence and recommend to the City
Council approval or denial of the requested zone change based on the proposed '
amendment consistency with the General Pian. The Planning Commission 's
recommendation wiff be forwarded to the City Councit for a fiinal decision.
3 . Specific Plan - Adoption of a Specific Plan to ensure a comprehensive
development and advance the goafs and objectives of the General Plan .
A Specific Plan is a regulatory tool that local govemments � se to implement the General
Plan and guide development in a locafized area . A Specific Plan is able to focus on the
unique characteristics of a specific area , by customizing the planning process and land
use regu �ations for that area . A Specific Plan provides for flexibility and encourages
innovative use of land resources and devefopment of a variety of fand use types .
5
7he use of a Specific Plan has been chosen to guide the development in this particular
instance given the unique size , configuration , access and proximity of 1he .site to the
freeway. It is staff's belief that additional regulatory measures are warranted to
safeguard future development opportunities and attain the desired level of quality and
coherent compatibie community design . Additiona{ly, it is important to estabiish
development standards (e.g. , permitted uses , setbacks , landscaping , sign criteria ,
subdivision, etc. ), design guidelines, and public improvement requirements that would
_ facilitate the goals of ihe Generai Plan and augment the City's revenue base to better
support public services and facilities. Additionally, the proposed Specific Plan uses will
permit drive-through facilities without a Conditionai Use Permit.
The primary issues addressed in the proposed Specific Pla� are: rest�icted uses ,
minimum site size, and special freeway-oriented freestanding sign criteria. The Specific
Plan restricts .the type of permiited uses to primariiy retaii sales tax producers. Aiso , it
prohibits the subdividing of the lot, except for commercial condominiums. �astiy, a
single 60-foot high doubie-faced freestanding sign with a maximum 880 square feet of
sign face area(incfudes both sign faces-440 square feet each) would be permitied on
the site. The sign would be allowed to advertise any and all approved tenants on-site.
The Pfanning Commission is to weigh ali evidence and recommend approval of or
denial of the proposed Specific Plan based on the determination that it promotes
and advances the goals and objectives of the General Plan. The Planning
Commission's recommendation wiil be forwarded to .he City Council for a final
decision.
4. Conditional Use Permit - Allow for the development of the site as a retail
shopping centec
The requested Conditional Use Permit (CUP) is contingent upon the General Plan
Amendment, Zone Change and Specific Plan . lf the Gene�al Plan Amendment, Zone
Change and Specific Plan are successful , the proposed project requires approval of a
CUP. Therefore, the CUP can only be approved and valid with the approval of the
General Plan Amendment, Zone Change a�d Specific Plaa .
in e ach o f t he C ity's z oning d istricts , u ses a re d ivided i nto two categories : permitted
uses , and pe�mitted uses subject to a conditional use permit. Permitted uses are those
that have been categorized and determined to be compatible with each other when
certain predetermined standards a nd conditions ( i . e . p arking , s etbacks, I ot coverage,
landscaping , height requirements , etc. ) have been met (also referred to as ministerial
actions ). On the other hand , uses permitted subject to a conditional use permit are
those , which have a speciai impact or uniqueness s�ch that their effect on the
surrounding environment cannot be determined in advance of the use being proposed
for a particular location (also known as an adjudicative actions). The approval or denial
is at the discretion of the Planning Commission . Nevettheless, in both cases, all
development must be designed to be compatible with existing and future land uses , and
be reviewed through the City's Development Review process .
s
The City's Developme� t Code (Section 22 . 10 .030, Table 2-6 ) permits the development
of shopping centers in the G2 zone, provided the City'� Planning Commission first
approves a CUP . The CUP is required to determine whether the proposed use should
be permitted by weighing the public need for and the benefit to be derived from the use
against the impact, which it may cause. Additionaliy, this discretionary approval process
aims to e nsure t hat t he p roposal i s c onsistent w ith the City's General Pian land use
policies and zoning standards ; provide for quality site design , layout and architecture ;
and promote a rational design transition with adjacent properties .
As previously mentioned , the Community Development ard Services Department and
other City Departments and Divisions (i.e. Planning , Building and Safety, and Public
Works/Engineering) have reviewed the project through the City's Development Review
process . The development review process enables the various City Departments and
Divisions to check development proposals for conformity with the provisions established
in the City's Municipal and Development Code. Additionaily, the review process is to
ensure that each development proposal is designed to be compatible with any existing '
structures on-site and(or the neighboring prope�ties. In this way, the quality and
economic health of our residential , commercial and industrial districts are maintained .
Staff's primary concern is in regards to the proposed hotel operation . it is intended for
` occupancies that extend beyond several days. Chapter 3 . 16 of the Diamond Bar
Municipal Code establishes provisions to collect a transiant occupancy tax from the
hotel operator for each room that is consecutively occupied up to 30 days . While staff is
generally supportive of the use as providing a needed service , and recognizes that the
nature of the proposed business is to accommodate longer stays, we also seek
assurances to prevent the hotel development from becoming a de-facto apartment
building . This would result in a substantial loss in revenue for the City from the transient
occupancy tax, and be contradictory to the General Plan and proposed Specific Plan
goals and objectives. It has the ability to diminish the intended retaiUcommercial land
use framework. Therefore , staff recommends, as a condition of approval , that the
transient occupancy tax will be required for each day a room is occupied in accordance
with locai and State law.
All City Departments and Divisions have reviewed the proposal and based on the
submitted design , recommended operating procedures, and on- and off-site
improvements to improve ingress and egress , staff is of the opinion that the following
required findings (Section 22 . 58 . 040 — Conditional Use Permits of the DBDC) can be
made in the affirmative .
1 . The proposed use is allowed within the subject zoning district with the approval
of a Conditional Use Permit and complies with all other applicable provisions of
this Development Code and the Municipal Code;
2 . The proposed use is consistent with the General Plan and any appiicable 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;
�
4. The s ubject s ite i s p hysicaily s uitable f or t he t ype a nd d ensity/intensity o f u se
being proposed including access , provision of utilities, compatibility with adjoining
land uses , and the absence of physical constraints;
5. Granting the Conditionai Use Permit wili not be detrimental to the public interest,
health , safety, convenience, or welfare, or injuricus to persons , property, or
improvements in the vicinity and zoning district in �rhich the property is located ;
and
6 . The proposed project has been reviewed in compliance with the provisions of the
Caiifornia Environmental Quafity Act (CEQA).
The Planning Commission may approve, approve with conditions, deny, or continue the
Conditional Use Permit request. lf approved, the decision is contingent upon approvat of
the General Plan Amendment, Zone Change, and Specific Pla� by the City Council .
5 . Development Review - Approve the tocation , design , site plan configuration and
the overall effect of the proposed project.
The purpose of Development Review is to establish consistency with the General Plan
through the promotion of high aesthetic and functional standards to compliment and add
to the economic, physical , and social character of the City. The process also ensures
that new devefopment and intensification of existing development yields a pfeasant
Iiving , working , or shopping environment and attracts the interests of residents, workers,
shoppers , and visitors as the result of consistent exemplary design. 7he fol�owing
provides a n o verview o f t he p roposed d eve{opment a s i t r e{ates t o t he Deveiopment
Code and proposed Specific Plan standards, which are intended to minimize adverse
effects on surrounding properties and the environment.

{`j A compsehensive sign program wilt be required for the b�ilding wall, awning, and proposed monument
signs to integrate the project's signs with the design of the structures to achieve a unified architectural
statemenL '
As illustrated in the above chart, the proposed projecYs development standards meet or '
exceed the minimum Development Code requi�ements as they relate to the proposed
zoning classification and Specific Plan . The proposed contemporary architectural style .
will utilize a mixture of natural materiais that will be compatible with surrounding
development. As mentioned above, the landscaping exceeds the minimum requirement
and wiil assist in buffering adjacent land uses. The proposed freestanding sign reflects
the architectu�al styie of the proposed development. However, staff did have some
concerns rega�ding the ingresslegress to the proposed development.
7he project has a single entry point onto Brea Canyon Road , which has been designed
to City standards to handle the anticipated traffic volumes. 7herefore , it is staff's opinion
that implementation of the proposed project will not result in traffic generation above
that of planned system capacity. However, site and roadway improvements (Brea
Ganyon Road ) are necessary to ensure adequate ingress/egress from the site onto
Brea Canyon Road . A detailed Traffic Impact Analysis (RK Engineering Group , inc. ,
May 31 , 2002 ) has been prepared and reviewed by the City's Traffic Engineer. The
fo4lowing mitigation measures wil! be required as conditions of approval to ensure
project-related traffic impacts are less than significant.
1 . Provide a deceleretion lane into the project site for traffic heading north .
2 . install a raised median on Brea Canyon Road witti left turn pocket into the site
for southbound traffic .
3 . Provide a dedicaked left turn pocket and signal improvements at Lycoming
Street a nd B rea C anyon R oad t o allow for signal controlled independent left
turns and " U "-turns for north bound traffic.
4 . Instali a "pork chop" island at the entrance to the site to force tra�c north
exiting the property. Post "Right Turn Only" signs at the drive exit. The exact
location and size to be determined by the City's Engineer.
Based on the site design and recommended conditions , staff is of the opinion that the
following required findings to approve the Development Review can be made in the
affirmative .
9
1 . The design and layout of the proposed development is consistent with the
General Pian , development standards of the applicable district, design
guidelines, and architectural criteria for specialized area (e .g . , theme areas ,
specific plans , community plans , boulevards, or planned developments);
2 . The design and iayout of the proposed development will not interfere with the
use and enjoyment of neighboring existing or future development, and wiil not
create traffic or pedestrian hazards ;
3 . The architectural design of the proposed development is compatibfe with the
characteristics of the surrounding neighborhood and will maintain and enhance
the h armonious o rderly a nd a ttractive d evelopment c ontemplated b y C hapter
22 .48, the Ganeraf Plan , City Design Guidelines, or any applicable specific
plan ;
4 . The design of the proposed development will provide a desirable environment
for its occupants and visiting public; as well as , its neighbors through good
aesthetic use of materials, texture, and color that wili remain aesthetically
appealing ;
5. The proposed project will not be detrimental to the public heaith, safety or
welfare or materially injurious (e.g. , negative affect on prope�ty values or
resale(s ) of property) to the prope�ties or improvements in the vicinity; and
6 . The proposed project has been reviewed in compliance with the provisions of
the California Environmental Quality Act (GEQA) .
The Planning Commission may approve, approve with conditions, deny, or
continue the Development Review request. If approved, the decision is contingent
upon approval of the General Plan Amendment, Zone Change, and Specific Plan
by the City Councii.
6. Subdivision (Tentative Map) • Approval of a five (5) lot commercial
CondOmitllUm . (Subdivision Map Ac), Section 66426.(c): The land consists of a parcei or parcels of
land having approved access to a public street or highway, which comprises part of a tract of land zoned
for i�dustrial or commercial deveiopment, and which has the approval of the governing body as to street
alignments and widths .)
The proposai indicates five (5) parcels , thus requiring approval of subdivision . Based on
the submitted proposai , the proposed parcels are not self-sufficient in meeting the Gity's
required independent accessibility to a public right-of-way (Parcels 3 , 4 and 5 are
landlocked ) . Therefore , the applicant is requesting approval of a commercial
condominium subdivision , which will permit the division of land ac►d allow for
independent ownership and financing options . Commercial projects of this kind , which
include common access , parking and on-site maneuvering requirements, are handled
through recorded a recip{ocal parking , access and maintenance agreement (REA), prior
to final map approval . This agreement ensures that the project functions as
comprehensive and cohesive development. Staff recommends that an REA be adopted
and submitted to the City for review and approvai. Additionally,
The City' s Engineer has reviewed the proposed map and recommends several
conditions . It is staffs belief that the proposed subdivision is a reasonable division of
land , and together with the proposed provisions for its design and improvement, is
� o
consistent with the General Plan , the proposed Specific Pian and complies with the
Subdivision Map Act. Therefore, a recommendation of approval to the City Council '
cou{d be justified .
The Planning Commission is to make a recommendati�n for approval or denial of
the Map to the City Council. The City Council wiil render the finat decision .
7. Tree Permit - Allow for the removal and repiacement of a protected tree species .
As explained in Section 22 .38 .010-Tree Preservation and Protection of the
Development Code, trees are an important natural resource , contributing to the
environment by replenishing oxygen and counteracting air pofiution , controlling erosion ,
and providing wildlife habitat. The City's General Plan requires the preservation and
maintenance of certain native trees.
The i ntent i s t o p rotect a nd p reserve t hese t rees a nd w hen removai is allowed as a
resu�t of new development to require their replacement. There are a number of mature
trees currentfy on-site . However, a more thorough examination of the applicanYs tree
as-built survey and a fieid investigation revealed that the�e are no protected trees, as
identified by the City of Diamond Bar Development Code, to be removed . Several large
Brazifian Peppers, Eucalyplus, Ash , Palm , 8eeiwood and Oiive trees wifl be removed .
But, these are not listed as a protected species. However, Eucalyptus trees along the
freeway right-of-way will be retained and Eucalyptus trees along Brea Canyon Road will
be removed as necessary for widening the right-of-way. Nonetheless, the applicant
proposes to replace the removed trees with a significant number of 24-inch box trees. It
is s taff's o pinion t hat the landscaping as proposed will he!p to soften and enrich the
appearance of the project site as we11 a s p rovide a n a ppropriate b uffer b etween t he
adjacent land uses . The Planning Division shail review and approve a detailed
landscape pian prior to installation and the projecYs final inspection or Certificate of
Occupancy.
Staff recommends that the Planning Commission take no action on this
application request
ENVIRONMENTAL ASSESSMENT:
Pursuant to the provisions of the California Environmental Quality Act (CEQA) , Article 6 ,
Section 15070 , the City has determined that a Mitigated Negative Declaration of
Environmentai Impact is required for this project. Mitigated Negative Declaration of
Environmental Impact No. 2002-07 has been prepared and is made part of this
administrative record .
RECOMMENDATION :
Statf recommends that the Pianning Commission open ihe pubfic hearing , receive
testimony, close the public hearing and consider all of the evidence presented in
connection with the project proposai and direct staff to prepare resolutions of approval
11
with conditions , as appropriate for consideration at the next regularly scheduled
meeting.
In particular, staff recommends that the Planning Commission take the following actions
in sequence:
1 . Recommend to the City Councii approval of t he requested a mendment to t he
General Plan Land Use Element from Professionai Office to General
Commercial ; and
2 . Recommend to the City Councii approval of the requested Change of zone from

a) Have a su6s�antial adverse effect on n scer�ic vista?
No Impact. No sceuic vistas are present in the proximate vicinity of thz project site. Therefore, the nuxture
of one and tfuee-story devetopment wi(1 not be out of charactet wiUi o[her shuctures or uses in the area and
would not cause views from adjacent commercial ot nearby residential areas to be obstructed. The project
willnotresultinanysubstantial aesthetic c6anges over existing conditions and Qws no significant impacts
would occur and no mifigation measuces would 6e required.
b) Subslanlinlly danvage scenic resources, including, bul not lintited to, trees, rock oulcroppings, and hrsloric
buildings witGin a stnte scenic highway?
No Lnpact. The General Plan Circulation Element does not identify any state scenic higliways witlun the
City. Furtlietxnore, thefe are no significant uees, rock outcroppings, histocic buitdings or ott�er significant
scenic resources identifiedontheprojectsite. The[efore, no scenic resoutces would be damaged by the
implemeutation of the proposed project and no significant impacts would occur. No mitigation measures
would therefore be required.
c) SieGslantiallv degrade Jhe ezistrng visim! cl�aracler or qua(ity of Uie s.'te and its sinroundings?
No Lnpac4 Ttie pcoject site is cuaently utilized as a cecceational ve4uele storage yacd. Therefore, Uie
proposed commercial development will not degrade H�e existing visual character or quality of tl�e site. Future
conshuction at Uie project site will be short-term in nahue. Therefoce, the visuat character of the site and the
surrounding area would not be significantly afiected by the proposed project. In addition, the project site is
located in an area characterized by similar sized commercial developments. The commercial development wiil
be simi(ar ui scale and design will� the sucrounding area. No mitigafion measures would U�erefore be required.
d) Geate a r�e�v sourrn ojsuGstanlin[ light or glare, which wo�dd adversely aJfect day or nighttime views in

III. AIR OUALITY - Where available, t6e significance criteria estaUlished by the applicable air quality
management or air pollution control district may be relied upon lo make the following detemtinations.
WouW tl�e project: .
n) Conf7ic! irit6 or abs7ruc! irnplenierilafian ojdte npplicable air quality plare ? �
No LnpacL Dus[, both small diameter respirable matter (PMio) and larger, heavier pacticulates, is nottnally

discharge N�rough a controlled source, they are called "fugitive eayssions." Particulate emission rates depend
on soil silt, soil moistwe, wind speed, arca disturbed, number of velucles, deptl� of disturbance or excavation,
e�c.
Fugili� e dusl emissious are estimated at approximately 100 pounds per day per acre disturbed in the absence
of any dust contro) measures being app(ied. Wateting is generally assumed to reduce ihis rate by 50 percent, �
wi� h rcduclions up in RO perccni possiblc Ihinugh �hc usc of chcmical bindcrs ur ulhcr nggressivc dusl canlrai

acre distwbed �vhen slandard dust contro( procedures required by SCAQMD Rule 403 are used. Ciurent Rule
403 requirements are more stringen[ than wl�en the 26.4 pound per acre estimate was developed. Cunently
required enhanced dust conhols procedures can substantially fiu�titer reduce Uie average daily PMio envssion
rale.

Gcneral Plan AmrnAment 2002-01 - 850 Orea Canyon 2oad

'fhe proposed project will be constcucted in a period of approximately 12- 18 months. The estinuated amount of
PM�a tl�at the area would be subject to for tlus activity would be approximate(y 171 .60 pow�ds per day during
tlils 12- I8 month period. All indiwted amounls of PM�o w'ould be fiuther reduced because consWction
activity woutd be scaled 6ack o� stopped during period of high winds. Constant monitoring of the
conswction activity by the City of Diamond Bar will insure compliance wilh the AQMP requirements.
The applicable air quatity management plan for the project area is tlie 1997 Air Quality Management Plan
(AQMP) prepared by SouHi Coast Air Quality Management District (SCAQMD). CEQA requires that
projects be consistent with tlie AQMP. A consistency determination plays an essential role in local agency
project review by li�ilcing local platuiing and unique individual projec[s to the AQMP in the following
ways: 1) It futftlls the CEQA goal of fuily infom�ing loca( agency decision-makecs of the enviromnental
costs of the project under consideration at a stage early enough to ensure that air quality concerns are fully
addressed; and 2) it provides tl�e local agency with ongoing information assuring local decision-mekers [hat
they are making real conhibutions to clean air goais contained in the AQMP. The AQMP provides
standards of concentration for seven (7) air po(lutants: ozone, carbon dioxide, nitrogen dioxide, sulfur
dioxide, susQended particutate matter, sulfates, lead, as wel( as visibility-reducing padicles. Onty new or
amended Generat P(an elements, Specific Plans, and significant projects need to undergo a co�sistency
. ceview. This is because the AQMP strategy is based on pro}ections from local Generat P1ans. "Che project
is consistent with the General Plan in that there will be no net inerease in planned commercial designated
land.
The project will not geuerate any sta[ionary source emissions addressed by the AQMP, and the project wili
meet the SCAQMD Rule 403 standard dustcontrol procedures, therefore no mitiga[ion measures would
thercfore be required.
b) Vio/a�e miy air qualiry standard or conhibute substantially to an ezisting or projeclecf air qualiry
violalion ?
Less Than Significant Impact. Construction of the proposed project will require grading. The grading
activities wili resuit in the generation oF dust The greatest potential for fugitive dust generation is during
roogh grading, and from hauling the excavated soils out of the project area to a fill site. In addition to
fugitive dosl emissions, eq�ipmen[ exhaust will be released into the ahnosphere during the excavation
activities. Workers comnmting to and from the construction site wili generate some mobile-source
emissions. T hese s hort-tenn c onshuction-related impacls, althougl� not considered signiftcant, may be a
ttuisauce to adjacent and nearby urban tand uses. The constcuction peciod foc the proposed project is
approximalely 12- 18 months. 12- I8 months of conslruction, based on the size of the proposal, would
produce nunima{ enussions, wli'sch wou4d be significantly less than ihe establislied threshold. Additionafly,
grading activities would be stopped during periods of high winds. Standard construction practices include
thc use ot' watering and otlier metUods of controliing fugi[ive emissions. Construction equipment wili be
monitored lo insure proper maintenance. When construction is complefed, no air quality impacts are .
anticipated .

are designed to protect t6ose people most susceptible to further respiratory distress such as asthmatics, U�e
elderly, very young childreu, people already weakened by other disease or illness, and persons engaged in
shenuous work or exercise, called "sensitive receptors." Healthy adults can tolerate occasional exposure to ',
ait pollutant couceutrations considerably above diese minimum standa�ds before advetse effects are
observed. Constructiou activity may result in the generation of fugilive dust and emissions from convnuter ..
vel�icles and conshuction equipment dwing fhe 12- 18 month construction period. Althougls these
emissions may be considered a nuisance to adjoining land uses, they are considered to be minimal giveu the
scope of proposed development, and would be significantly 3ess than the established threshoid.
Additionatly, they will only be present during the shod grading phase of tl�is construction project. A
survey of the project area did not reveal the location of any land uses that would be considered sensitive
receptors. Tl�eretore, the proposed ptoject will not have an impact on sensi[ive receptors and no miligation
is thereCore required.
e) Creale objeclra�able oAors affecting a substmilral number ojpeople?
Less than Signifcant [mpact. During allowable construction work-hours, various types of conshuction .
equipment necessary to undertake grading and construction of the conunercial improvements will be used.
Most of tl�e constmction equ'spment will be diesel powered. The emissions from this equipment wi11 cause
a diesel odor that may be noticeable during nomial working hours within the immediate construction site.
Tliis may create objectionable odors and emissions during the sliort-term consttuction period. Any
perceptible impacts Crom conshuction equipment e�chaust wiil be coufined to occasiona( whiffs of
characteristic diesel exliaust odor, but such odors will not be in sufficieut concentrations to expose any
nearby individuals or uses of land to air pollution levels above acceptable standards. The area most
impactedbyconstructiouodoremissions is a radius of 50 to l00 feet from the source. Residential uses
located itt close proxinuty to tlie siles' nocQierly boundary aceoss tlie Los Angeles County Flood Control
Channel would be most directly affected. Constructiou equipment odors, which are not considered to be
significant, will cease aRer compietion of construction. I�io mitigation measures ate necessary.

No Impact. Tl�e project site is not considered a migratory wildlife comdor due to the existing surrounding
urban development. Moreover, there is no connection to any natural wildlife area. Therefore no substantial
impacts wiil occur as a result of project implementation. No mitigation measures would therefore be
required.

Less Than Significant Impact. Approvat of this project will result in the removal of a number of mature
California Pepper, Brazilian Pepper, Olive and Beefwood trees. The City's General Plan and impiementing
Development Ordinance requires the protection/preservation and maintenance of native trees, which
includes California Peppers. However, when the preservation oF a piotected tree is not feasible and would
compronuse the property's owner's reasmiable use and enjoyment of property or surtounding laud it may
be removed provided it is replaced in accordance with the City's adopted standards. Replacement trees
must be planted at a rttinimum 3 : 1 ratio on lots greater than 20,000 square feet with a minimum box size of

No 1 �npacL L iquefaction refers to loose, saturated sand or gravet deposits ihat lose their load
suppo�ting capabiGty when sub}ected to intense shaking. Liqueiaction potential v azies based upon
on-site soil composition and groundwater depth.
The Califomia Deparhneat o[ Conservation is mandated by the Seismic Aazards Act of 1990 to
identify and map the state's most prominent earthquake hazards, including areas wliere
eaRhquakes are likely to cause shaking, liquefaction or otlier ground failute. The Califomia
' Department of Conscrvation Division of Mines and Geology has recently updated existing seismic
hazard maps for portio�s of southern California, including ii�e area covering the potential project
site. The State Geologis[ released tUe o�cia( maps March 25, t999.
The updated map lhat covers the project area indicates that the pro,ject site is not located in a
Iiquefaction zone. No sig�ificant impacts would result from ll�e development of the proposed
- project. No mitigation measures ace necessary.
iv). Lnnds7ides ?
No Impact. Land sliding is a type of erosion in which masses of earfh and rock move down slope
as a single unit. Susceptibility of slopes [ 01 andslides a nd o tl�er fomis o f s lope fai(ure depend o n
several factors. These are usualiy present in combination and include, but are not limited to, steep
slopes, condition of rock and soit materials, presence of water, fo�mationat conhzets, geologic shear
zones and s eismic activity. The area for the proposed commercial improvements is relatively tlat.
1'he probability that this area is subject to landslides is cemofe at best The chance of {ands{ide
and/or mudslide is not wnsidered to be au impact. Therefore, no mitigation measures would be
required.
y) Xesult in substmrti�l soit erosion orlhe loss ojlopsoil?
No Impact The project would not result in any uses that cause substa�tiat soil erosion. Once grading and
compaction of the project area are compteted, the project si[e witi be paved and landscaped. Thecefore, soil
erosion would be minimal and temVorary in nature. Since tlie site has not been used for agricultural
production, the loss of topsoil wouid no[ be considered significan[. In addition, compliance with the
General ConSWction ActiviUes Stomi Water Pemil[ and development oF Best Management Practices

No Impact. In I 972, the Federal W ater Pollution Conhol Act (also refeired lo as tlie Clean Water Act
[CWA)) was antended to provide that the discharge oC pollutants to watets of the Uiuted States from any
point source is unlawful uniess the discl�arge is in compliance with a National Pollulant Discharge
Elimination System (NPDES) pemtit. The 1987 amendments ro tl'�e CWA added Section 402(p), which
estabtisties a Cmutework for regulating municipat aud industrial stocm water dischacges under the NPDES
Program. On November 16, 1990, the U.S. Environmenta( Protection Agency (USEPA) published final
regu{ations that establish stoxm water pemvt applicafron requirements for specified categories of industries.

'fhe proposed project would be subject to the NPDCS program, because the project involves a consltuction
sile greater thau ftve acres. However, as part of the approval ptocess and prior to permit issuance, the
NPDES �equiremenls woutd need to be satisfied (permit) so as not to violate any wates quatity standa�ds or

Less Than Significant Impact. Tlie equipment used on the project site will generate noise above N�e
ambient levels for linuted periods of time during cons Wction. Due to the proximity of the conshuction site
to esisting residential buifdings, and due to the leve(s of noise generated by coi�struction equipment witliout
nutigation measures, adjacent properties would be subjected to higher than ambient noise Ievels during

buildings, located wilhin 1 ,000 feet oF constcnction equipment noise geuerators, would be subject to noise
of approximately 65dB(A). Normal building wnshvction methods and materials will reduce interior noise

c) A subslantial permmten! inwe�se in an,bieri! �+orse levels i�: �he praject vrcrnrry above levels existing
�vithour d�e project?
No Impact. The proposed conshuction activlty is tempocary and noise will localize and be confined to the
development site. At U�e completion of the consWction ac[ivity no permanent increase in ambient noise
ievels will be genewted by the commercial use.
d) A s«Gslnn�ial [empa•ary or periodic ii�crease rn ambre�tt rtoise [erels in !/�e projec! vicrnity abo��e levels
, exrstirrg tivUhout 1he project?
Less Tltan Signifcant Impnct. The equipment used on the project site witl generate noise above ihe
ambient levels for timited periods of time during conshuction. Due to the proximity of t6e conshuction site
to existing residential buitdings, and due to the levels of noise generated by constmc[ion equipment witliout
miligatiou measures, adjacent properties would be subjected to temporary or periodic higher than ambient
noise levels duriug nomial business hours during the conskuction period. I[ is anticipated that in a worst
case scenario buildings, located witliint ,000feetofcottshuctionequipmen4noisegeneratots, wouldbe
subject to noise of approximately 65dB(A). However, tlie Commm�ity Noise Equivatent Levet (CNEL) for
new constmction wi{I be enforced by the C'tty fox the project.
TUe City's General Plan Noise Element indicates tl�at a Community Noise Equivalent Level (CNEL) of 55-
60 is considered as "Normally Acceptable" for commercial areas. The amount of noise intcusion with
respect to tl�e existing sunounding buildings during conslruction wil( vary depending upon where tUe
loealized constnsction is occurring. The consWction equipment will be required to compty with City
regulations wit6 respect to the use of mufflers. When Qie construction is completed, no noise impacts are
anticipated. The proposed conunercial improvements are compatible with a nd the e quivalent o f e xisting
area improvements, and as such will not generate any increase in ambie�t noise above current vicinity
levels. The potentia( short-te�m noise impacts generated by construction equipmen[ wil) be mitigated by
Hie use of muf(lers. Conshuction activity will be confined to normal business hours. Tlierefore, no
significant impacts would occur a�d no mitigation measures would be required.

Potentialiy Significant Unless Mitigated. Tlie project has a single entry point onto Brea Canyon Road,
which has been designed to City standards to handle the anlicipated tra�c volumes. Therefore,
implementation of the proposed project wi(l uot result in haffic gecseration above that of planned system
capacity. However, site and roadway improvements (Brea Canyon Road) are necessary to ensure adequate
ingresslegress from the site onto Brea Canyon Road. A detailed TrafFc Impact Analysis (RK Engiueering
Group, Inc. , May 31 , 2002) has been prepared and reviewed by the City's Traffic Engineer. The following
mitigation measures will be implemen�ed to ensure projec[-related traffic impacts are less than significant.

Field Observation Report
date : January 22 , 2001
client: CASCO Corp .
project: ESA Diamond Bar i
present: Cliff Hoskins
This is an observation report for the proposed ESA site in Diamond
Bar Califomia .
Hoskins+Hoskins Corp : was asked to evaluate the trees on the
site , identifying those that are suitable to retain in the future
landscape . .
General description :
The site is currently being used as an recreational vehicle storage
lot. There are rows of Ash and Pepper trees along the borders of
the site and scattered trees (mostly Ash) through the site . It
appears that the trees were intended as shade and screening from �
the freeway . The trees along the adjacent storm drain channel
appear to be outside of the property and therefore out of
consideration . The trees along the freeway are appear to be on
site . It is our professional opinion that the Ash and California
Pepper trees along the freeway edge be retained . Any other trees ,
( Brazilian Pepper, Olive , Beefwood ) shouid be removed and the
roots removed from the ground . Ail of the retained trees should be
pruned and shaped . All the trees that are topped and stunted or
twisted should be removed . Poorly pruned trees present a safety
hazard and effect their long term health .
All of the trees in the interior of the site should be removed and
their roots removed from the ground . This includes all the Ash ,
Brazilian Pepper, the Mulberry and Palm trees . The Ash are
misshapen from poor pruning as is the Mulberry tree . The Palm
could be relocated but does not fit into proposed �andscape
concept . '
The trees along Brea Canyon Bivd . are a mixed group of Ash ,
Brazilian Pepper , Podocarpus and Eucalyptus . The Ash trees were
not pruned to shape and some are irreparable . The same is true for
the Brazilian Pepper, Podocarpus and Eucalyptus . A few of the
Eucalyptus are salvageable with careful pruning .
All of the retained trees need to be feed and permanent irrigation
instalied at the base of each tree .
Piease see AITA plan herewith with trees to be retained and
deleted identified . We will return to the site and flag all the trees to
be removed at your request.

EXTENDED STAY AMERICA '
TRAFFIC IMPACT ANALYSIS '
DIAMOND BAR, CALIFORNIA
L EXECUTIVE SUMMARY
A. Project Description
The proposed project consists of a 166-room business hotel , three (3)
freestanding restaurants and one office/retail building pad . The site is currentiy
occupied with a recreation vehicle storage facility . The project location is shown
in Exhibit A . The site pian for the project is illustrated in Exhibit B.
B . Purpose of Report and Studv Obiectives
The purpose of this tra�c impact analysis is to eva;uate the development of the
Extended Stay America project from a tra�c circulation standpoint. Study
objectives include ( 1 ) documentation of existing traf`c conditions in the vicinity of
the site ; (2) calculation of the existing plus project canditions ; (3) caiculation of the
Opening Year (2004) traffic conditions without and w ;th the project; (4) evaluation
of ingress/egress points for the development; and (5) determination of on-site and
off-site improvements and system management actions needed to achieve City of
Diamond Bar level of service requirements.
C . Site Location
The project site is located on the east side of Brea Canyon Road between
Lycoming Street and the State Route 60 (SR-60) westbound off-ramp in the City of '
Diamond Bar . Exhibit A illustrates the tra�c analysis study area which was
established in discussions with City of Diamond Bar siaff.
D . Studv Area and Methodoloay
The study area includes the following intersections :
Brea Canyon Road (NS) at.
• Lycoming Street (EV�
1
• SR-60 Westbound Ramps (E11�
• Golden Springs Drive ( Ei/�
• West Project Driveway (EV�
SR-60 Eastbound Ramps (NS) at:
• Golden Springs Drive (E1/�
Northerly Project Driveway (NS) at:
• Lycoming Street (EV�
1 . ICU Method
The technique used to assess the operation of an intersection is known as
Intersection Capacity Utilization (ICU) . To calculate an ICU the vo�ume of
tra�c using the intersection is compared with the capacity of the
intersection . ICU is usually expressed as a percent. The percent
represents that portion of the hour required to provide su�cient capacity to
accommodate all intersection traffic if all approaches operate at capacity.
An explanation of Level of Service is included in Appendix "A".
Calculation Method :
a . Intersection Capacity Utilization ( ICU) for study area intersections;
b . Saturation Flow Rate :
Saturation flow value of 1 ,600 vehicles per Iane per hour for through
lanes , 1 , 600 vehicles per hour for single turn lanes and 2 , 880 for
dual turn lanes ; no adjustments are used for protected movements
with dedicated lanes (including both right and left turns) .
c . Ciearance Internal :
A clearance interval factor of 10% (0 . 10) is applied to the ICU
calculations .
4
d . Level of Service Ranges :
The foliowing thresholds are used in assigning a letter value to the
resulting LOS: '
CRITICAL b'OLUME TO
LOS CAPACITY RATIO
A 0 .00 - 0 .60
, B 0.61 - 0. 70
C 071 - 0. 80
D 0 . 81 - 0 . 90
E 0 . 91 - 1 . 00 '
F > 1 . 00 '
e. Peak-Periods :
Weekday peak-hour analysis periods are defined as follows :
7 : 00 to 9 : 00 AM
4 : 00 to 6: 00 PM
f. Peak-Hour:
The highest one-hour period in both the AM and PM peak periods ,
as determined by four consecutive 15-minute count periods are used '
in the ICU calculations. Both AM and PM peak hours are studied .
g . Peak-Hour Data Consistency:
Variations in peak-hour volumes can affect LOS calculations
because they vary from day-to-day. To rninimize these variations , no
counts are taken on Mondays , Fridays , holidays or weekends . The
traffic ccunt worksheets for this study is included in Appendix "B".
5
h . Right Turn Movements :
If the distance from the edge of the outside through lane is at least
19 feet and parking is prohibited during the peak period , right turning
vehicles may be assumed to utilize this "uno�cial" right turn lane .
Otherwise, all right turn tra�c is assigned to the through lane . if a
right turn lane exists, right turn activity is checked for conflicts with
other critical movements . It is assumed that right turn movements
are accommodated during non-conflicting left turn phases
(e.g . , northbound right turns during westbound left turn phase) , as
well as non-conflicting through flows (e. g . , northbound right turn
movements and north/south through fluws). Right turn movements
become critical when conflicting movements (e . g . , northbound right
turns, southbound left turns , and eastbound through flows) represent
a sum of V/C ratios which are greater than the normal through/left
turn critical movements .
2 . HCM Method
However, ICU method is not an appropria;e method for analyzing an
unsignalized intersection . Since the intersection of the project driveways at
Brea Canyon Road and Lycoming Street are unsignalized intersections ,
another analysis method is needed . Therefore, the HCM (Highway
Capacity Manual) method is also used in this study. The HCM method
evaluates the average delay per vehicle at the intersections .
The current technical guide to the evaluation of average delay is the
Highway Capacity Manual ( HCM) 2000. HCM 2000 defines level of service
as a quaiitative measure which describes operational conditions within a
traffic stream , generaliy in terms of such factors as speed and travel time,
freedom to maneuver, traffic interruptions , cornfort and convenience , and
safety . The criteria used to evaluate �OS (Level of Service) conditions vary
based on the type of roadway and whether the traffic flow is considered
interrupted or uninterrupted .
The definitions of level of service for uninterrupted flow (flow unrestrained
by the existence of traffic control devices) are :
6
. LOS "A" represents free flow. Individual users are virtually ',
unaffected by the presence of others in the traffic stream.
. LOS "B" is in the range of stable flow, but the presence of other
users in the traffic stream begins to be noticeable . Freedom to
select desired speeds is relativeiy unaffected , but there is a slight
deciine in the freedom to maneuver.
. LOS "C" is in the range of stable flow, but marks the beginning of the '
range of flow in which the operation of individuai users becomes
significantly affected by interactions with others in the traffic stream .
. LOS "D" represents high-density bui stable flow. Speed and
freedom to maneuver are severely restricted , and the driver
experiences a generally poor level of comfort and convenience .
. LOS "E" represents operating conditions at or near the capacity
levef . A11 speeds are reduced to a low , but refative{y uniform value.
Smaii increases in flow will cause breakdowns in t�a�c movement
. LOS "F" is used to define forced or breakdown flow. This condition
exists wherever the amount of traffic approaching a point exceeds
the amount which can traverse the point. Queues form behind such '
iocations .
The definitions of level of service for interrupted tra�c flow (flow restrained
by the existence of traffic signals and other traffic control devices) differ
slightly depending on the type of traffic controL '
The level of service is typicaily dependent on t;�e quality of traffic flow at the
intersections along a roadway . Highway Capacity Manual (HCM) 2000
methodology expresses the ievel of service at an intersection in terms of
delay time for the various intersect+on approaches . The NCM uses diffetent
procedures depending on the type of intersection control .
7
Study area intersections which are stop sign controiled with stop control on
the minor street only have been analyz�d using the unsignalized
intersection methodology of the HCM . F or these intersections , the
calculation of level of service is dependent on the occurrence of gaps
occurring in the tra�c flow of the main street. Using data coilected
- describing the intersection configuration and t�affic volumes at this location ,
the levei of service has been calculated .
The level of services for cross-street stop control intersections are defined
as follows :
LEVEL OF AVERAGE CONTROL
SERVICE DEIAY
A 0 - 10
B > 10 - 15
C > 15 - 25
D > 25 - 35
E > 35 - 50
F > 50
3 . Roadwav Link V/C Ratio
In addition to intersection analysis , the roadways in the vicinity of the project
site have been analyzed by volume-to-capacity (V/C) ratio. The City of
Diamond Bar requires Level of Service "C" (V/C = 0 . 80) as its evaluation
criteria for roadway segment analysis. The fc`.lowing summarizes the daily
traffic capacities for different types roadways :
TYPE OF ROAOWAY MAXIMUM DAILY CAPACITY
6 Lanes Divided 56 , 300 vehicles per day
4 Lanes Divided 37 , 50� vehicles per day
4 Lanes Undivided 25 , 000 vehicles per day
2 Lanes Undivided 12 , 500 vehicles per day
Local Road 3 , 100 vehicles per day

E. Principal Findinps
1 . The proposed development is projected to generate approximatety 3 , 936 ;
trip-ends per day with 287 vehicles per hour tluring the AM peak hour and
306 vehides per hour during the PM peak hour. Taking into consideration '
pass-by trips for the various uses , the project is expected to generate a
total of approximately 1 , 954 new trip-ends per day with 148 vehicles per
hour during the AM peak hour and 158 vehicles per hour during the PM
peak hour.
2 . For existing traffic conditions, the study area intersections are operating at '
Level of Service "D" or better during the peak hours , except at Golden
Springs Drive and Brea Canyon Road. All roadway links in the study area
are currently have V/C ratios better than 0. 80 except for Golden Springs
Drive east of Brea Canyon Road .
3 . For existing plus project conditions, all study area intersections are
projected to operate at Level of Service "D" or better with the exception of
Brea Canyon Road at the SR-60 westbound ramp which is projected to
operate at Level of Service "D" during the AM peak hour and Level of
Service " E" during the PM peak hour and at tha intersection of Brea Canyon
Road , at Golden Springs Drive , which is projected to operate at Level of
Service " E" during the AM peak hour and Level of Service " F" during the PM
peakhouc
4 . For Opening Year (2004) without project traffc conditions all of the study
area intersections are projected to operate at Level of Service "E" or worse
during the peak hours with existing lane configurations . All the roadway '
links are projected to have V/C ratios better than 0 . 80 except for Brea
Canyon Road from SR-60 westbound ramps and to north of Lycoming
Street and Goiden Springs Drive from SR-60 eastbound ramps to east of
Brea Canyon Road .
9
5. For Opening Year (2004) with project traffic conditions , the study area
intersections are projected to operate at Level of Service "E" or worse
duri�g the peak hours with existing lane configurations with the exception of
the project driveways. All the roadway links are projected to have V/C
ratios better tnan 0. 80 except the following roadway segments:
• Brea Canyon Road north of SR-60 westbound ramps
• Golden Springs Drive east of Brea Canyon Road
6. The addition of the project traffic produces an increase of more than 0. 02 in
the ICU value (significant impact) for Opening Year (2004) at only one
intersection . As shown in Table 13, the project does have a significant
traffic impact at the intersection of Brea Canyon Road at �ycoming Street.
Therefore , the project should contribute to the improvements to that study
area intersection .
7 . Based on the roadway segment analysis, the addition of the project tra�c
produces an increase of more than 0 . 02 in the WC ratio value (significant
impact) at one location (Brea Canyon Road north of SR-60 westbound
ramps) . Therefore , the project creates significant traffic impact at fhis one
roadway segment and the project should contribute to this improvement.
8 . For Opening Year (2004) with project traffic conditions, the study area
intersections are projected to operate at unacceptabie level of service
during the peak. hours with existing lane configurations . However, with the
recommended street improvements, all the study area intersections are
projected to operate at Levef of Service "D" or better. Most of the roadway
links are projected to have V/C ratios better than 0 . 80 except the following
roadway segments, in which they are projected to be over-capacity:
• Brea Canyon Road north of SR-60 westbound ramps to north
of �ycoming Street
• Golden Springs Drive between SR-60 eastbound ramps to
east of Brea Canyon Road .
10
9. Based on the HCM intersection analysis , the unsiynalized intersections of west '
and north project driveways are projected to operate at acceptable level of
service for Opening Year (2004) with project traffic conditions .
10. This traffic study is in compliance with the tra�c study requirements for the Los
Angeles County CMP (Congestion Management Program) . The level of
service standards utilized in this study, are equal to or more conservative than
the CMP standards .
F. Prolect Recommendations
The Opening Year circulation recommendati�ns are summarized in
Exhibits C and D. '
1 . The proposed project will have one access driveway on Brea Canyon Road
and one on Lycoming Street north . The westerly and northerly project
driveways should be stop-controlled with minimum widths of 30 feet. The
west project driveway should be restricted io right-in/right-out and left-in
access with raised median channelization along Brea Canyon Road .
Project recommendations are shown in Exhibit C . The north driveway
should be a full access as shown in Exhibit D .
2 . The project should contribute on a fair-share basis to the foliowing
intersection improvements recommended for the Opening Year conditions
(see Exhibit C ) :
a . For the intersection of Lywming Street at Brea Canyon Road :
• Provide a westbound left turn lane
This improvement is feasible . by restriping Lycoming Street to have a ,
two-way left turn median .
11
3 . Restripe Brea Canyon Road from the westbo�nd SR-60 Freeway off-ramp
to Lycoming Street to provide three (3) lanes ir each direction .
4 . Tra�c signing/striping should be implemented in conjunction with detailed
construction plans for the project. See Exhibit D for recommended location
- of stop signs .
5. Sight distance at the project access driveways should be reviewed with
respect to City of Diamond Bar sight distance standards in conjunction with
the preparation of precise grading and landscape plans.

II. SETTING
A . Land Use
1 . Existinp Land Uses
The site is currently a recreation vehicle storage facility . Adjacent uses
includ.e the following :
North - Fast food restaurant
South - Freeway (SR-60)
East - Flood Controi Channel
West - Residential development
2 . Approved Future Development
Pursuant to conversations with cities of Diamond Bar and Industry staff,
there are three (3) approved future developments in the vicinity of the
project site in the City of Industry . These projects are shown in Exhibit E .
B . Studv Area Roadwav Svstem
1 . Area of Siqnificant Traffic Impact '
Existing roadways in the study area include Lycoming Street, Brea Canyon
Road and Golden Springs Drive .
LVcominq Street is currently a two lane divided roadway, and it is classified '
as a Collector roadway (64 foot right-of-way) .
Brea Canvon Road is currently a four lane divided roadway , and it is
classified as a Major arterial ( 100 foot right-of-way) north of Golden Springs
Drive and a Secondary arterial (80 foot right-of-way) south of Golden
Springs Drive .

III. PROJECTED TRAFFIC
A. Site Traffic
1 . Trip Generation '
Trip generation represents the amount of t:affic which is attracted and
produced by a development. Trip generation for this project has been
based upon the specific land uses which is planned for the development '
The proposed project consists of a 166-room business hotei , three
freestanding restaurants and one officelreta �l bui{ding pad . The site is
currently occupied with a recreation vehicle storage facility. '
Trip generation rates for this project are shown in Table 1 . The trip
generation rates are based upon data developed by the Institute of
Transportation Engineers (ITE) . The current RV storage facility generates
nominal traffic.
Both daily and peak-hour trip generation for the proposed project are shown
in Table 2 . The proposed development is projected to generaie
approximately 3 , 936 trip-ends per day with 28' vehicles per hour during the
AM peak hour and 306 vehicles per hour during the PM peak hour. With
pass-by trips for the various uses , the project is expected to generate a
total of approximately 1 , 954 new trip-ends par day with 14S vehicles per
hour during the AM peak hour and 157 vehic{es per hour during the PM
peak hour . The traffic study has not taken any credit for the trips
generated from the existing RV storage facility . Therefore , this represents
a conservative traffic impact assessment. '
TFip generation for approved future cumulative projects in the area , which
are expected to be completed by Year 2004 , are shown in Table 3 .
2 . Trlp Distribution
I rip disUibution represents the directional orientation of traffic to and from
the project site . Trip distribution is heavily influenced by the geographical
Iocation of the site , the proximity to the regional freeway system ,
21
employment, commerciai and community facilities . The directionai
orientation of tra�c was determined by evaluating existing and proposed
land uses within the community and existing traffic volumes.
Trip distributions for this study have been based upon nea�-term conditions ,
based upon those highway facilities which are in place . The outbound and
inbound trip distribution patterns for the project are graphically depicted on
Exhibits I and J , respectively.
The trip distributions for cumulative projects are shown in Exhibit K.
3. Modal Split
The traffic reducing potential of public transit has not been considered in
this report. Essentially the traffic projections are "conservative" in that
public transit might be abie to reduce the traffic volumes. Currently; Golden
Springs Road is served by the Foothill Transit route 482 buses .
4 . Trip Assiqnment
The assignment of tra�c from the site to the adjoining roadway system has
been based upo� the site's trip generation , trip distributions , proposed
arteriai highway and locai street systems. Project related daily traffic
volumes and the projeci AM and PM peak hour intersection turning
movements are shown on Exfiibit L.
B . Future Traffic
1 . Openinq Year (2004) Tra�c
To account for areawide growth on roadways , Opening Year tra�c volumes
have 6een cafcuVated based on a 2 percent annuai growth rate of existing
traffic volumes over a three and-a-half year period ( 1998-2002}. Areawide
growth has been derived from the comparison of the 1998 counts
conducted by RKJK & Associates , Inc. and 2002 traffic counts conducted
for RK ENGINEERING GROUP , INC . Total growth rate over two years is
approximately 4 % .
25
Areawide growth plus cumulative project tra�� has been added to existing
daily and peak hour traffc volumes on surro� nding roadways , in addition
to traffic generated by the project. Existing traffic volumes are shown on
Exhibit G , and they are based on manual AM and PM peak hour turning
movement counts conducted for RK ENGIf� EERING GROUP , INC . in '
February, 2002 . Traffic count worksheets are included in Appendix "B" .
The roadway average daity traffic (ADT) volumes have been estimated by
RK ENGINEERING GROUP , INC . using the following formula for each
intersection leg :
PM Peak Hour (Approach + Exit Volumes) " 10 = Daily Leg Volume
The formula is based on the assumption that ; 0% of the daily traffic occur
during PM peak houc ,
Exhibit M shows the traffic volumes which can be expected for Opening
Year (2004) without project traffic conditions .
Exhibit N shows the traffic volumes which can be expected for Opening
Year (2004) with project tra�c conditions .

IV. TRAFFIC ANALYSIS
A. Level of Service at Existinq Conditions
1 . ICU
Intersection Capacity Utilization (ICU) for existing tra�c conditions have
been calculated and are shown in Table 4. The ICU are based on manual
AM and PM peak hour turning movement counts conducted for RK
ENGINEERING GROUP , INC . in February, 2002 (see Exhibit J ) . Tra�c
count worksheets are inc►uded in Appendix "B".
Tab{e 4 summarizes existing ICU's at the siudy area intersections with
existing lane configurations. As shown o� Table 4 , the study area
intersections are currently operating at Level of Service "D" or better during
the peak hours , except for Golden Springs Drive and Brea Canyon Road
with existing lane configurations . ICU caicuiation worksheets are included
in Appendix "C".
Z . V!C Ratio
Table 5 summarizes the existing volume-to-capacity (V/C) ratio of the
roadways in the vicinity of the project site. As shown on Table 5 , all the
roadway links currently have V/C ratios better than 0 . 80 except for Golden
Springs Drive east of Brea Canyon Road .
B . Levef of Service at Existinq PI�s Proiect Conditions
1 . ICU
Intersection Capacity Utilization ICU for existing plus project conditions have
been calculated and are shown in Table 6 . As shown in Table 6 the study
area intersections are currently operating at Level of Service "D" or better
during the peak hours , except for the interseciion of Brea Canyon Road at
SR-60 westbound ramps , and Brea Canyon Road at Golden Springs Drive .
!CU calculations are included in Appendix "C" .
33
2 . V/C Ratio
Table 7 summarizes the existing plus project volume capacity ratio of
roadways in the vicinity of the project. As shovdn in Table 7 , all the roadway
links currentiy have V/C ratios better than 0 . 80 except for Golden Springs
- Drive east of Brea Canyon Road .
C . Level of Service at Openinq Year (2004) Without Proiect
1 . ICU
ICU for Opening Year (2004) without project traffic conditions have been
calculated and are shown in Table 8 . Table 8 summarizes ICU's at the
study area intersections with existing lane cenfigurations . Opening Year '
(2004) AM and PM peak hour tuming movement volumes without the
project are shown on Exhibit M .
As shown in Table 8 , most study area intersections are projected to operate
at Level of Service "E" or worse during the peak hours , with existing lane
configurations . ICU calculation worksheets are included in Appendix "E".
There are three (3) intersections which would require improvements to
achieve Level of Service "D" or better for Opening Year 2004 without project
as shown in Table 8 . Potential improvements required to achieve Level of
Service " D" or better are shown on Table 8 . These improvements would
include the addition of an additionai westbound left turn lane on the SR-60
westbound ramp and a free right tum on southbound Brea Canyon at
Golden Springs . These additional lanes would require substantial
improvements and modification to existing roadway and adjacent land uses ,
including additional right-of-way . However, it should be noted , that as
discussed in the next section of this report, the project does not have a ,
significant impact to either of these two intersections . In order to achieve
Levei of Service " D" or better at the intersection , significant improvements
are required at these two intersections , which would require detailed design
evaluation to determine the precise impact to the adjacent land uses .
37
2 . V/C Ratio
Table 9 summarizes the V/C ratio of the surrounding roadways for the
Opening Year (2004) without project traffic conditions. As shown on Table
9 , al{ the roadway links are projected to have V/C ratios better than 0 . 80
except Brea Canyon Road no�th of SR-60 we�atbound ramps , Brea Canyon
Road north of Lycoming Street and Golden Springs Drive east of SR-60
eastbound ramps and east of Brea Canyon Road .
D . Level of Service at Openinq Year (2004) With Proiect
1 . ICU and HCM
ICU and HCM (Highway Capacity Manual) intersection delays for Opening
Year (2004) with project traffic conditions have been calculated and are
shown in Table 10. Table 10 summarizes ICU's and HCM intersection
delays at the study area intersections with existing lane configurations and
with improvements . Opening Year (2004) AM and PM peak hour turning
movement volumes with the project are shown on Exhibit N .
As shown in Table 10 , most of the study area intersections are projected to
operate at Levei of Service "D" or worse during the peak hours , witli
existing lane configurations . The improvements required to met Level oF
Service "D" or better are aiso shown in Table 1U. ICU and HCM caiculation
worksheets are included in Appendix "F" .
There are three ( 3) intersection which wou{d r �quire increments to achieve
level of Service " D" or better fo� Opening Year 2004 without project as
shown in Table 10 . Potential improvements require to achieve Level of
Service " D" or better are shown on Table 10 . These improvements would
include the addition of an additional westbound left turn lane on the SR-60
westbound ramp and a free right turn on southbound Brea Canyon at
Golden Springs . These additional lanes would require substantial
improvements and modification to existing roacJway and adjacent fand uses .
It should be noted , however, that as discussed in the next section that the
project does nok have a significant impact to either of these two
40
intersections . In order to achieve Leve� of Senrice "D" or better at the
intersection , significant improvements are required at these intersections .
The improvements necessary to achieve Level of Secvice "D" or better at
the three intersections is as follows
SR-60 EB Ramps ( NS) at:
• Golden Springs Drive (EWj
Convert the existing westbound right turn iane !o a "free" right turn iane.
Brea Canyon Road (NS) aY.
• Lycoming Street (EV1�
Stripe an additional southbound through lane on Brea Canyon Road and
stripe a westbound left turn lane on Lycoming Street.
• Golden Springs Drive (EVN�
Convert the existing southbound right turn larie to a "free" right turn lane.
Provide northbound right turn overlap phasing and restripe to provide and
additionai eastbound through lane . As noted cn Page 37 of this report, the
first and third improvements mentioned above wouid require significant '
changes to the existing intersections . However, the project does not have a
significant impact to these intersections .
2 . V/C Ratio
Table 11 summarizes the V/C ratio of the surrounding roadways for the
Opening Year (2004) with project tra�c conditions . As shown on Table 11 ,
roadway links which are projected to have V/C ratios worse than 0 . 80 are
as foflows :
. Brea Canyon Road no�th of SR-6Q wastbound ramps
. Brea Canyon Road north of Lycoming Street
43
. Golden Springs Drive between SR-60 eastbound ramps and
Brea Canyon Road
. Golden 5prings Drive east of Brea Canyon Road
E . Pro'tect Siqnificance Impact to Intersections and Roadwav Seqments
1 . Intersections
In order for the project to have a significant impact it has to increase the
ICU by 0. 02 . An assessment of the Opening Year 2004 with project
intersections level of service with and without the project is shown in
Tabfe 12 . The project wili not have a significant impact to most
intersections within the study area. As shown in Table 12 , the only
intersection which the project would increase the ICU by more than 0 . 02 is
the intersection of Brea Canyon Road an� �ycoming Street. This
intersection would need modification to achieve Level of Service "D" or
better during the PM peak hour.
2 . Roadwav Seqments
In order for the project to cause a significant impact the project has to
change the V/C ratio of roadway segments by more than 0. 02 . A summary
or the Opening Year 2004 project significant evaluation is included in
Tabie 13 . As shown in Table 13 , the pruject does not contribute a
significant traffic impact to roadway segments with the exception of Brea
Canyon Road north of SR-60 westbound ramp and Lycoming Sireet, east
of Srea Canyon Road .
Lycoming Street east of Brea Canyon Road is operating significantly under
its design capacity and does not require any improvements . Brea Canyon
Road north of westbound ramp , adjacent to the project is over its design
capacity of this roadway . Restriping Brea Canyon Road to provide three (3)
lanes in each direction will mitigate this situation . Additionally, the proposed
raised median to be consiructed by the project from the westbound ramps
to Lycoming Street wou4d contro{ access in this area and further mitigate
this situation in conjunction with the restriping to provide these lanes in each
direction .
45
F. Proiect Traffic Contribution
The project fair share contributions have been calculated for the study area '
intersections . The project share of intersection improvements has been based on
the proportion of project peak hour traffic volumes contributed to the intersection
- relative to the total new peak hour Opening Year (2004) tra�c volumes . Table 14
presents a summary of the project traffic contribution to the study area
intersections and also identifies whether the project has a significant impact to the
intersection .
The only intersection which the project has a significant impact that requires
improvements is Brea Canyon Road at l.ycoming Street. The project's fair share
percent wntribution to this intersection is 17. 3% during the AM peak hour and '
16. 3% during the PM peak hours. Table 15 summarizes the project traffic
contribution to significantiy impacted intersections.
48
V. RECOMMENDATIONS
A. Site Access
The Opening Year circulation recommendations are summarized in Exhibit C a�d
Exhibit D .
1 . The proposed project wiil have one access driveway on Brea Canyon Road
and one access to Lycoming Street through the existing restaurant.
2 . The Srea Canyon access couid be a right-inJright-out and ieft turn access .
In order to prevent left turns out of the project on to Brea Canyon Road a
raised median is recommended along Brea Canyon Road from the westerly
SR-60 ramp to Lycoming Street. The raised median should include a
50-foot southbound left turn pocket into the proposed Brea Canyon Road
driveway . The driveway should have a minimum width of 30 feet and be a
curb return type driveway , with a curb return radius of 30 feet.
3 . The Lycoming Street driveway shou{d occur at the existing location of the
restaurant driveway . It is recommended that stop signs be installed as
shown in Exhibit D to better control tra�c within the driveway. Both of the
projects driveways should be stop sign controled at Brea Canyon Road and
Lycoming Street .
B . RoadwaV improvements
1 . Off-Site
For Opening Year (2004 ) tra�c conditions with the project and with existing
lane configurations , some of the study area intersections are projected to
operate at less than Level of Service " D". The only intersection that the
pro� ect will have a significant impact is the intersection of Brea Canyon
Road at Lycoming Street . in order to mitigate intersection , a westbound left
turn iar�e is required on lycoming Street ta accommodate the AMIPM peak
hou� traffic volume . The project should provide a fair share contribution of
between 16 . 3 to 17 . 3% of improvement costs for this modification . The
51
project wiil not have a significant impact to other study area intersections for '
Year 2004 conditions .
The projecYs restriping of Brea Canyon Road to three (3) lanes in each
direction and construction of a raised median along Brea Canyon Road
- from the SR-60 westbound ramps to Lycoming Street will mitigate the
projecYs V/C ratio of this roadway segment.
2 . On-Site
a . Traffic signing/striping should be implemented in conjunction with
detailed construction plans for the project.
b. Sight distances at the project access driveways should be reviewed
with respect to City of Diamond Bar sight distance standards in
conjunction with the preparation of precise grading and landscape
plans .
c. Provide a northbound right turn lane into the project driveway on
Brea Canyon Road .

1 . (C t M .thod
_ The technique used to assess the operation of an intersection is known as
Intersection Capacity Utiiization (iCU). To calculate an ICU the volume ot
tra�c using the intersection is compared with the capacity of the
intersection. ICU is usually expressed as a percent. The percent
represents that portion of the hour required to provide su�cient capacity to
accommodate ail intersection tra�c if ali approaches operate at capacity.
An explanation of Levei of Service is included in Appendix "A".
Caiculation Method: .
a . { ntersection Capacity Utiiization (ICU) for study area intersections;
b. Saturation Fiow Rate:
Saturation flow value of 1 , 600 vehicles per lane per hour for through
lanes , 1 ,600 vehicles per hour for si��gle turn lanes and 2, 880 for
dual turn lanes ; no adjustments are ��ed for protected movements
with dedicated lanes (inciuding both rigi it and left turns).
c. Clearance Interna{:
A clearance interval factor of 10% (0 . 10) is appiied to the ICU
calculations.
d . Level of Seroice Ranges:
The following thresholds are used in assigning a letter value to the
resuiting LOS :
3
CRITICAL VOLUME TO '
j„Q� S:APAGITY RATIO
A 0 .00 - 0 .60
B 0 .61 - 0 . 70
C 0. 71 - 0.80
D 0 .81 - 0 .90
E 0.91 - 1 .00
F > 1 . 00
e . Peak-Periods:
Weekday peak-hour analysis periods are defined as follows :
7 : 00 to 9:00 AM
4 : 00 to 6 :00 PM
f. Peak-Hour:
The highest one-hour period in both the AM and PM peak periods ,
as determined by four consecutive 15-minute count periods ate used
in the ICU caiculations . Both AM and PM peak hours are studied.
g . Peak-Hour Data Consistency:
Variations in peak-hour volumes can affect LOS calculations
because they vary from day-to-day. To minimize these variations , no
counts are taken on Mondays , Fridays , holidays or weekends . The
tra�c count worksheets for this study is included in Appendix "B".
h . Right Turn Movements :
If the distance from the edge of the outside through lane is at least
19 feet and parking is prohibited during the peak period , right turning
vehicles may be assumed to utilize this "uno�ciai" right turn lane.
Otherwise , ail right turn tra�c is assigned to the through lane. If a
right turn lane exists , right turn activity is checked for conflicts with
other critical movements . It is assum�d that right turn movements
are accommodated during non-coriflicting left turn phases
4
(e.g . , northbound right turns during westbound left turn phase), as
well as non-conflicting through flows (e.g. , noRhbound right turn
movements and north/south through flows). Right turn movements
become critical when conflicting movements (e.g . , northbound right
turns , southbound ieft turns, and eastbound through flows) represent
a sum of V/C ratios which are greater than the normal through/left
turn critica! movements.
2. H • M M .th�d
However, ICU method is not an appropriate method for analyzing an
unsignalized intersection. Since the intersection of the project driveways at
Brea Canyon Road and Lycoming Street are unsignalized intersections ,
another analysis method is needed. Therefore, the HCM (Highway
Capacity Manual ) method is also used in this study. The HCM method
evaluates the average delay per vehicie at the intersections.
The current technical guide to the evaluation of average delay is the
Highway Capacity Manual (HCM) 2000 . HCM 2000 defines level of service
as a qualitative measure which describes operational conditions within a
traffic stream, generally in terms of such factors as speed and travel time ,
freedom to maneuver, traffic interruptions, comfort and convenience, and
safety. The criteria used to evaluate LOS (Level of Service) conditions vary
based on the type of roadway and whether the tra�c flow is considered
inXerrupted or uninterrupted .
The definitions of level of service for uninterrupted flow (flow unrestrained
by the existence of tra�c control devices) are:
. LOS "A" represents free flow. Individual users are virtually
unaffected by the presence of others in the traffic stream.
. lOS "B" is in the range of stable flow, but the presence of other
users in the tra�c stream begins to be noticeable. Freedom to
select desired speeds is relatively unaffected, but there is a slight
decline in the freedom to maneuver.
5
. �OS "C' is in the range of stabie flow, but marks the beginning of the '
range of flow in which the operation of individual users becomes
significantly affected by interactions with others in the traffic stream .
. LOS "D" represents high-density b�t stable flow. Speed and
freedom to maneuver are severely restricted , and the driver
experiences a generally poor level of cumfort and convenience .
. L' OS "E" represents operating conditions at or near the capacity
level. Aii speeds are reduced to a low, but relatively uniform value.
Small increases in flow will cause breakdowns in traffic movement.
. LOS "F" is used to define forced or breakdown flow. This condition
exists wherever the amount of traffic approaching a point exceeds �
the amount which can traverse the poi�t. Queues form behind such
locations .
The definitions of �evel of service for interrupted traffic flow (flow restrained
by the existence of traffic signals and other traffic control devices) differ
slightly depending on the type of tra�c control .
The level of service is typically dependent on the quality of traffic flow at the
intersections along a roadway. Highway Capacity Manual (HCM) 2000
methodology expresses the Ievei of service at an intersection .in terms of
delay time for the various intersection approaches. The HCM uses different
procedures depending on the type of intersection controi.
Study area intersections which are stop sign controlled with stop control on
the minor street only have been analyzed using the unsignalized
intersection methodology of the HCM . For these intersections , the
calculation of level of service is dependent on the occurrence of gaps
occurring in the traffic flow of the main street. Using data collected
describing the intersection configuration and traffic volumes at this location ,
the level of service has been calculated .
6
The level of services for cross-street stop control intersections are defined
as follows
LEVEL OF AVERAGE CONTFtOL
SERVICE DELAY
A 0 - 10
B > 70 - 15
C > 15 - 25
, D > 25 - 35
E > 35 - 50
F > 50
3. Roadwa� Link V/C Ratin
In addition to intersection analysis , the roadways in the vicinity of the project
site have been analyzed by volume-to-capacity (V!C) ratio. The City of
Diamond Bar requires Level of Service "C" (V/C = 0.80) as its evaluation
criteria for roadway segment analysis . The following summarizes the daily
tra�c capacities for different types roadways:
TYPF OF ROADWAY MAXiMI ) M DAII Y C:APAC:ITY
6 Lanes Divided 56,3J0 vehicies per day
4 Lanes Divided 37 ,5U0 vehicles per day
4 Lanes Undivided 25 ,000 vehicles per day
2 Lanes Undivided 12 , 500 vehicles per day
Local Road 3 , 100 vehicles per day

1 . The proposed deve4opment is projected ta generate approximately 3,936
trip-ends per day with 287 vehicles per hour during the AM peak hour and
306 vehicles per hour during the PM peak hour. Taking into consideration
pass-by trips for the various uses , the projc;ct is expected to generate a
tota{ of approximately 1 ,954 new trip-ends per day with 148 vehicies per
hour during the AM peak hour and 158 vehicles per hour during the PM
peak hour.
2 . For existing traffic conditions, the study area .ntersections are operating at
Level of Service "D" or better during the peak hours , except at Golden
Sp�ings Drive and Brea Canyon Road . All rcadway links in the study area
are currently have V/C ratios better than 0. 80 except for Golden Springs
Drive east of Brea Canyon Road .
3 . For existing plus project conditions , all st��dy area intersections are
projected to operate at Level of Service "D" or better with the exception of
Brea Canyon Road at the SR-60 westbound ramp which is projected to
opetate at �evel of Service "D" during the Afvi peak hour and Level of
Service "E" during the PM peak hour and at th,� intersection of Brea Canyon
Road , at Golden Springs Drive, which is projected to opecate at Level of
Service "E" during the AM peak hour and Levc{ of Service "F" during the PM
peak ho� r .
4 . For Opening Year (2004 ) without project traffc conditions aI! of the study
area intersections are projected to operate at Level of Service "E" or worse
during the peak hours wiih existing lane con .igurations , Ail the roadway
links are projected to have V!C ratios bettar than 0.80 except for Brea
Canyon Road north of SR-60 westbound ramps and to north of Lycoming
Street and Golden Springs Drive from SR-60 eastbound ramps to east of
8rea Canyon Road .
9
5. For Opening Year (2004 ) with project traffic conditions, the study area
intersections are projected to operate at Level of Service "E" or worse
during the peak hours with existing lane configurations with the exception of
the project driveways . Aii the roadway links are projected to have V/C ratios
better than 0 . 80 except the following roadway segments:
. Brea Canyon Road north of SR-60 �restbound ramps
. Golden Springs Drive east of Brea Canyon Road
6 . The addition of the project traffic produces an increase of more than 0 . 02 in
the ICU value (significant impact) for Opening Year (2004 ) without project
vs . with project traffic conditions at only one intersection . As shown in Table
13, the project does have a significant traffic impact at the intersection of
Brea Canyon Road at Lycoming Street. Therefore, the project should
contribute to the improvements to that study area intersection .
7. Based on the roadway segment analysis , the addition of the project tra�c
produces an increase of more than 0 .02 in tl �a V/C ratio value (significant
impact) for Opening Year (2004) without project with project traffc
conditions at one location (Brea Canyon Road north of SR-60 westbound
ramps) . Therefore , the project creates significant tra�c impact at this one
roadway segment and the project should contribute to this improvement.
8 . For Opening Year (2004 ) with project tra�c conditions , the study area
intersections are projected to operate at unacceptable level of service
during the peak hours with existing lane configurations . However, with the
recommended street improvements , all the study area intersections are
projected to operate at Level of Service "D" or better. Most the roadway
links are projected to have V/C ratios better than 0.80 except the foilowing
roadway segments , in which they are projected to be over-capacity:
. Brea Canyon Road north of SR-60 westbound ramps to north
of Lycoming Street
. Golden Springs Drive between SR-60 eastbound ramps to
east of Brea Canyon Road .
10
9. Based on the HCM intersection analysis, the unsignalized intersections of
west and north project driveways are projected to operate at acceptable
level of service for Opening Year (2004) with p�oject tra�c conditions.
F. PrnYPct RecommPndations
The Opening Year circulation recommendations are summarized in
Exhibits C and D .
1 . The proposed project will have one access driveway on Brea Canyon Road
and one on Lycoming Street north. The westeriy and northerly project
driveways should be stop-controlied with minimum widths of 30 feet. The
west project driveway should be restricted to right-in/right-out and left-in
access with raised median channelization along Brea Canyon Road .
Project recommendations are shown in Exhibit C. The north driveway
should be a fui{ access and modified as shown in Exhibit D to avoid the
angular intersection with the existing parking lot.
2. The following project should contribute on a fair-share basis to the following
intersection improvements recommended for the Opening Year conditions
(see Exhibit C):
a . For ihe intersection of Lycoming Street at Brea Canyon Road:
. Provide a westbound left turn lane
3 . Traffic signing/striping should be implemented in conjunction with detailed
construction plans for the project. See Exhibit D for reconfiguration for the
existing parking lot within the adjacent restaurant.
4 . Sight distance at the project access driveways should be reviewed with
respect to City of Diamond Bar sight distance standards in conjunction with
the Qreparation of precise grading and landscape plans .

Iil. PR�IEGTED TRAFFIG
A. Site Traffic
1 . Tr ,in Generation
Trip generation represents the amount of iraffic which is attracted and
produced by a development. Trip generation for this project has been
based upon the specific fand uses which is planned for the developrnent.
The proposed project consists of a 166-;oom business hotel , three
freestanding restaurants and one office/retail building pad . The site is '
currently occupied with a recreation vehicle storage facility.
Trip generation rates for this project are s; iown in Table 1 . The trip
generation rates are based upon data developed by the Institute of
Transportation Engineers (ITE ). The current RV storage facility generates
nominal traffic.
Both daily and peak-hour trip generation for the proposed project are shown
in Tabie 2 . The proposed development is projected to generate
approximately 3 ,936 trip-ends per day with 287 vehicles per hour during the
AM peak hour and 306 vehicles per hour during the PM peak hour. With
pass- by trips for the various uses , the project is expected to generate a
total of approximately 1 , 954 new trip-ends per day with 148 vehicies per
hour during the AM peak hour and 157 vetiicles per hour during the PM
peak hour. The tra�c study has not tal:en any credit for the trips .
generated from the existing RV storage faciliiy. Therefore, this represents
a conservative traffic impact assessment.
Trip generation for approved future cumulative projects in the area , which
are expected to be completed by Year 2004 , are shown in Table 3 .
2 . Trio Distribution
Trip distribution represents the directional ori� ntation of tra�c to and from
the project site . Trip distribution is heavily infiuenced by the geographical
location of the site , the proximity to the regional freeway system ,

orientation of tra�c was determined by eva �uating existing and proposed
land uses within the community and existing t��a�c volumes .
Trip distributions for this study have been based upon near-term 'conditions ,
based upon those highway facilities which ar� in place. The outbound and
inbound trip distribution patterns for the project are graphically depicted on
Exhibits I and J , respectively.
The trip distributions for cumulative projects a ;e shown in Exhibit K. ,
3. Mod_�I Solit I
The traffic reducing potentiai of public transit has not been considered in .
this report. Essentiaily the traffic projections are "conservative" in that
public transit might be able to reduce the traffic volumes. Currently, Golden
Springs Road is served by the Foothill Transit route 482 buses .
4. Trio Assignment
The assignment of traffic from the site to the adjoining roadway system has
been based upon the site's trip generation , trip distributions , proposed
arterial highway and local street systems. Project related daily traffic
volumes and the project AM and PM peak hour intersection turning
movements are shown on Exhibit L. •
B . F�ture Traffir.
1 . Qo�g Y�r_(7004 ) Traffic
To account for areawide growth on roadways , Opening Year traffic volumes
have been calculated based on a 2 percent annual growth rate of existing
traffic volumes over a three and-a-half year period ( 1998-2002) . Areawide
growth has been derived from the comparison of the 1998 counts
conducted by RKJK & Associates , Inc. and 2002 traffic counts conducted
for RK ENGINEERING GROUP , INC . Total growth rate over two years is
approximately 4% .

Areawide growtfi has been added to daily a� id peak hour tra�c volumes
on surrounding roadways, in adclitiQn to tra�fic generated by the project.
Existing tra�c volumes are shown on Exhitit G , and they are based on
manual AM and PM peak hour turning mo� ement counts conducted for
RK ENGINEERING GROUP, INC . in Feb� uary, 2002 . Traffic count
worksheets are included in Appendix "B" . The roadway average daily
traffic (ADT) voiumes have been estimat�d by RK ENGiNEERING
GROUP , INC . using the following formula for each intersection feg:
PM Peak Hour (Approach + Exit Volumes) ' 10 = Daily Leg Volume
The formula is based on the assumption that 10% of the daily traffic occur
during PM peak hour.
Exhibit M shows the traffic volumes which can be expected for Opening
Year (2004) without project traffic conditions .
Exhibit N shows the tra�c volumes which can be expected for Opening
Year (2004 ) with project tra�c conditions .

delays at the study area intersections with e�cisting lane configurations and
with improvements . Opening Year (2004) AM and PM peak hour turning
movement vofumes with ihe project are shown on Exhibit N .
As shown in Table 10 , most of the study area intersections are projected to
operate at Levei of Service "D" or worse during the peak hours , with existing
lane configurations . The improvements required to met Level of Service "D"
or better are also shown in Tab{e 10 . iCU and HCM caicuiation worksheets
are inciuded in Appendix "F" .
2 , V/C Ratio
Table 11 summarizes the V/C ratio of the surrounding roadways for tiie
Opening Year (2004) with project t�affic conditions . As shown on Table 11 ,
roadway links which are projected to have ViC ratios worse than 0.80 are
as follows :
. Brea Canyon Road north of SR-6� westbound ramps
. Brea Canyon Road north of Lycoming Street
. Goiden Springs Drive between SR-60 eastbound ramps and
Brea Canyon Road
. Golden Springs Drive east of Brea Canyon Road
E . Proi rt Signifi ^ n imnact to Inters _ .tions and Roadway S�gments
1 . Intersections
fn order for the project to have a significant irnpact it has to increase the
lCU by 0 . 02 . An assessment of the Oper� ing Year 2004 with project
intersections level of service with and without the pro}ect is shown in Table
12 . The project will not have a significant impact to most intersections
wiihin the study area . As shown in Table 12, the oniy intersection which the
pro}ect woufd increase the fCU by more than 0 . 02 is the intersection of Brea
Canyon Road and Lycoming Street. This intersection would need
modification ko achieve Level of Service "D" or better during the PM peak
hour.

2 . Roadway segments
In order for the project to cause a significant impact the project has to
change the V/C ratio of roadway segments by more than 0 . 02 . A summary
or the Opening Year 2004 project significant evaluation is included in Table
13 . As shown in Table 13 , the project does not contribute a significant
traffic impact to roadway segments with the exception of Brea Canyon
Road north of SR-60 westbound ramp and Lycoming Street, east of Brea
Canyon Road . '
Lycoming Street east of Brea Canyon Road is operating significant�y under '
its design capacity and does not require any improvements. Brea Canyon
Road north of westbound ramp, adjacent to the project is over its design
capacity of this roadway. However, the proposed raised median to be
constructed by the project from the westbound ramps to Lycoming Street
would mitigate this situation .
F . Project Traffir. Contribution
The project fair share contributions have been calculated for the study area
intersections . The project share of intersection impravemen#s has been based on
the proportion of project peak hour traffic volumes contributed to the intersection
relative to the tota � new peak hour Opening Year (2004 ) traffic volumes . Tabie 14
presents a summary of the project traffic contribution to the study area
intersections and also identifies whether the project has a significant impact to the
intersection .
The only intersection which the project has a significant impact that requires
improvements is Brea Canyon Road at Lycoming Street. The project's fair share
percent contribution to this intersection is 17 . 3 % during the AM peak hour and
16 . 3 % during ihe PM peak hours . Tabie 15 summarizes the project traffic
contribution to significantly impacted intersections .

The Opening Year circulation recommendations are summarized in Exhibit C and
Exhibit D.
1 . The psoposed project will have one access driveway on Brea Canyon Road
and one access to Lycoming Skreet through the existing restaurant.
2 . The Brea Canyon access couid be a right-in/right-out and left turn access .
In order to prevent left turns out of the project on to Brea Canyon Road a
raised median is recommended along Brea Canyon Road from the westerly
SR-60 ramp to Lycoming Street. The raised rnedian should include a 150-
foot southbound left turn pocket into the proposed Brea Canyon Road
driveway. The driveway should have a minimum width of 30 feet and be a
curb retum type driveway , with a curb return radius of 30 feet.
3 . The Lycoming Street driveway should occur at the existing location of the
restaurant driveway. It is recommended that a po�tion of the restaurant
driveway parking area be reconfigured as shown in Exhibit "D" to better
channelize traffic within the driveway. Both of the projects driveways should
be stop sign controled at Brea Canyon Road a;id Lycoming Street.
B . Roadway Impt �vPm .Pnts
1 . Off_ � itP
For Opening Year (2004) traffic conditions witF� the project and with existing
lane configurations , some of the study area i;itersections are projecied to
operate at less than Level of Service " D". The only interseckion that the
project wiii have a significant impact is the intersection of Brea Canyon
Road at Lycoming Street. In order to mitigate intersection , a westbound left
turn lane is required on Lycoming Street to ac�ommodate the AM/PM peak
hour traffic volurne . The project should provide a fair share contribukion of
between 16 . 3 to 17 . 3 % of improvement costs for this modification. The
49
project will not have a significant impact to other study area intersections for
Year 2004 conditions.
The projecYs construction of a raised median along Brea Canyon Road
from the SR-60 westbound ramps to Lycoming Street will help to mitigate
the projecYs V!C ratio of this roadway segment.
2 . On -Site
a . Traffic signi�g/striping should be implemented in conjunction with
detailed construction pians for the project.
b . Sight distances at the project access driveways should be reviewed
with respect to City of Diamond Bar sight distance standards in
conjunction with the preparation of precise grading and landscape
plans .

E. Gateway Center Dtive , Diamond Bar, CA 91765
DATE: December 2 , 2002
The referenced project was presented to the Planning Commission on October 22 , 2002 '

additional time to prepare a traffic impact analysis report. At the November 26 , 2002
Planning Commission meeting , the Planning Commission continued this projecYs public
hearing to December 10, 2002 due to the appiicant' s request in a correspondence dated
October 31 , 2002 stating a scheduling conflict.
The applicant submitted a traffic impact analysis report to the City on October 21 , 2002 .
The report was prepared by Linscott Law & Greenspan Engineers and is dated October

♦ Site access/internal circulation ;
♦ Existing year 2002 traffic counts ;
♦ Estimated project traffic generation/distribution/assignment;
♦ Estimated cumulative project traffic generation/distribution/
assignment;
♦ AM/PM peak hour intersection capacity for existing and future conditions without and .

♦ Key I �tersections :
0 Brea Canyon Road at Golden Springs Drive ;
0 Gateway Center Drive at Golden Springs Drive;
0 Copley Drive at Goiden Springs Drive ; and
0 Golden Springs Drive at Grand Avenue .
The results of the study indicates that: the proposed project will not have a significant
impact on the four key intersections studied ; the project driveway will be abie to
accommodate i �gress and egress traffic without undue congestion ; the approximate throat
length of 50 feet at the project driveway is sufficient for storing potential queuing vehicles ;
the on-site circulation layout is adequate ; and curb return radii are adequate for small
service/delivery trucks, as well as trash trucks. However, the City's traffic engineer, Warren
Siecke, has reviewed the traSfic impact analysis and site access evaluation report. It is
required that the applicant address Mr. Siecke's comments and concerns . Afier the
applicant addresses Mr. Siecke's comments and concerns and the results is traffic
impacts , the app{icant wil{ be required to correct traffic impacts and/or pay their "fair share"

the applicant over the past several weeks. Lack of documentation came to the
attention of staff in the past few days and staff asked the applicant whether he wished
to proceed or continue the project. The property owner and applicant requested staff
to proceed with the project.

BACKGROUND :
The property owner, Dr. Acbar Omar and appiicant, Southwest Design are requesting
approvai of Development Review No . 2002-03 (pursuant to Code Section 22 .48 .020 .A .)
in order to construction a two-story, office building of approximately 25 ,000 gross square '
feet (23, 250 net square feet) to be utilized for general office . Future tenants are unknown
at this time.
The project site is located at 21671 E. Gateway Center Dr. (Lot 4, Tract No. 39679) , within
a corporate complex identified as Gateway Corporate Center. It is an irregular-shaped ,
vacant lot, approximately 2 . 033 gross acres with an existing pad of approximately 40 ,000
square feet. The site is bound by a descending slope on the north facing the Orange (SR-
57) Freeway, by Gateway Center Drive on south , by Lot 5 — V-Tek on the west and the
1
Holiday Inn Select hotel on the east. The project site contains a sanitary sewer easement,
approximately ten feet wide , that follows the north property and angles toward the west
property line. The project site was mass graded as part of the overall grading for the
corporate complex. The pad area is generally free of vegetation with the exception of
moderate weed growth . The north descending slope is vegetated with trees and bushes
planted as part of the Gateway Corporate Center's master landscape plan .
Gateway Corporate Center is approximately 233 acres of which approximately 143 acres
are subdivided into lots to accommodate a mix development of office-professional, light
manufacturing, resiaurant and retaif . This business compiex was processed by Los
Angeles County and approved in the late 1980's. This approval incorporated a unilaterai
contract imposing land restrictions/development standards which the City adopted on
October 17 , 1989 .
The project site has a General Plan land use designation of Professional Office (OP) .
Pursuant to the General P1an , this fand use designation provides for the estabfishment of
office-based working environments for general , professional , and administrative offices ,
as well as support uses. Additional�y, development within the OP designation will maintain
a maximum floor area ratio (FAR) of 1 . 00. The proposed project is for office-based
businesses with a proposed FAR of 0 .28 . As such , it is consistent with the General Plan.
The zoning designation for the project site is Commerciaf-Manufiacturing-Bilfboard
Exclusion-Unilateral Cont�act (C-M-BE-UlL) . Pursuant to the Development Code,
standards for the Office , Business Park (OB) zone are applicable to this project. This
zoning designation permits large scafe, headquarters-type office facilities and business
park developments , and similar related compatible uses . Although future tenants are not
known at this time, the proposed office building will be able to accommodate office uses .
As such , the proposed project complies with the project site's zoning designation.
Generally , the following zones and use surround the project site: To the north is the
Orange Freeway (SR 57) ; and to the south , east and west is the C-M-BE-U/C zone.
Pursuant to the Gateway Corporate Center's Unilateral Contract, the maximum aUowable
FAR is . 50 and office uses are permitted. As such , the proposed project is consistent with
the FAR criteria and permitted office uses for Gateway Corporate Center.
Previously, the applicant submitted another development project for the subject site. The
projects , Conditional Use Permit No. 1990-070 and Development Review No. 93- 1 , was
approved by the Planning Commission tor the construction of a restaurant structure of
approximately 9 , 000 square feet.
ANALYSIS :
Development Review
The City's Development Code establishes a Development Review process. The purpose
of this process is to establish consistency with the Genera{ P1an through the promotion of
2
high aesthetic and functional standards to complement and add to the sconomic, physical ,
and sociai character of the City. The process will also ensure that new development and
intensification of existing development yields a pleasant living , working , or shopping
environment and attracts the interest of residents , workers , shoppers and visitors as the
result of consistent exemplary design .
- Pursuant to the Development Review Section 22 .48. 020 A. , an application for
Development Review is required for commercial, industrial and institutional development,
which involves the issuance of a building permit for construction or reconstruction of a
structure. Therefore the proposed project, a commercial development involving the
issuance of a building permit requires Development Review. Development Review is within
the Planning Commission's review authority.
In addition to complying with the City's Development Review process, the proposed project '
must comply with the land use restrictions imposed upon Gateway Corporate Center by
the adoption of the Unilateral Contract. The following is a comparative between the
Unilateral Contract's development standards and the proposed projecYs development
standards .

Parkina/Parking Lot Lighting '
Parking lot lighting and exterior site lighting was not submitted. Prior to the issuance of a
building permit, the applicant is required to submit an exterior lighting plan and a parking
lot lighting plan/study complying with the standards in the Development Code for the City's '
review and approvaL '
The City's Development Code requires one parking space for every 250 square feet of
gross floor area for medical offices ; one parking space for every 250 square feet of gross
floor area for general/administrative offices; and one parking space for every 300 square
feet of gross fioor are�a for banks/financial offices. However, adoption of the Unilateral
Contract imposes land restrictions and development standards within Gateway Corporate
Center that requires a general office use to provide one parking space for every 250 ,
square feet of net floor area. Therefore, the proposed project is required to provide and
does provide 93 parking spaces based on net floor area. The Unilateral Contact does aliow
compact parking stalls (30%) , but compact parking stalis are not proposed.
Traffic �
The applicant is required to submit a traffic impact analysis report for the City's review and
approval . The analysis is required to address off-site and o�-site circulation and present
corresponding mitigation measure addressing traffic impacts. As of the date of this report,
a traffic impact analysis report has notbeen submitted .
The proposed p�oject is required to comply with the City's Transportation Demand
Management standards (Code Section Chapter 22.40) . The applicability for these
standards begins with non-residential projects of 25,000 square feet. The proposed project
has a gross floor area of 25 , 000 square feet and will be required comply with the City's
Transportation Demand Management standards by displaying the following :
1 . Current maps , routes and schedules for public transit serving the site;
2 . Telephone numbers for referrals on transportation information including
numbers for the regional ride sharing agency and locai transit operations ;
3 . Ride sharing promotional material supplied by computer-oriented
organizations ;
4 . Bicycle route and facility information , including regional/local , and bicycle
maps and bicycie safety information ; and
5 . A list of facilities available for carpoolers , vanpoolers , bicyclist, and transit
riders and pedestrians at the site .
Geotechnicai Investigation
Although a flat pad exists on the site , some grading is proposed . Approximately, 3 ,760
cubic yards of cut and 1 ,275 cubic yards of fill will be utilized for a total of 5, 035 cubic yards
of earthwork . Approximately, 2 , 500 cubic yards of earth will be imported .
5
A geotechnical report has not been submitted for this project. However, a soils report was
submitted for the previous project (a restaurant structure) to be located on the project site
in a similar manner as the proposed buiiding with approximately the same amount of
earthwork. At that time, the project site was considered to be generaNy satisfactory for a
9 ,000 square foot restaurant structure if designed and constructed in accordance with the
building code requirements and recommendations within the soils report. Prior to the
issuance of any City permits, a geotechnical report based on the proposed project is
required for the City's review and approval
Buildina LocationlExtendinq Buildina Pad
As mentioned previously, the project site has a graded pad . The applicant has chosen to
utiiize the pad mainfy for parking. Approximately one-fourth of the building footprint wiil be
on the pad. The remainder of the building footprint will be located on the north down siope
facing the freeway. As a result, the building itself will be utilized to extend the pad. The
building' s north eievation incorporates a retaining wall of approximateiy 16 feet that wili
assist in extending the pad . The proposed building height of 56 feet includes the 16 foot
height of the retaining wall . In order to break-up the vertical monotony (at the north
eVevation) of a talf fiat wail , cornices (horizontai mofdings or bands) along with varying
planes, colors and windows are utilized. Additionally, the cornices, varying planes , colors
and windows are proposed on all building elevations.
Landscapinp
Landscapinglirrigation is proposed and a fandscape pian was submitted . The City's
Development Code requires that 20 percent of the site area be landscaped. As referenced
in the comparison matrix, Gateway Corporate Center requires that 15 percent of the gross
usabfe lot area to be iandscaped. Approximately 27 percent of the gross usable lot area
wiii be landscaped . The applicant is required to submit a final landscape/irrigation plan for
the City's review and approval prior to the issuance of a building permit. The landscape
plan shall inciude piant species, size , quantity and location , and existing planting on ail
slopes and the replacement of plant materiai o� the slopes that is damaged during
construction . It is required that the repiacement plant materials match the existing slope
landscaping . Additionally, all trees on the north facing slope adjacent to the building shali
be 24 inch box size and the proposed quantity of bougainvillea and acacia plants shali be
increased on this slope, thereby enhancing slope coverage and screening of the building's
retaining wali . Furthermore, the proposed project is required to comply with the City's
established Water Efficient Landscape Regulations and will be plan checked according{y.

PART 4 - EVALUATION OF ENVIRONMENTAL IMPACTS
1 . A brief explanation is required for all answers except " No ImpacY' answers that are
adequately supported by the information sources a lead agency cites in the
parentheses following each question. A " No ImpacP' answer is adequately
supported if the referenced information sources show that the impact simply does
not apply to projects like the one involved (e.g. the project falis outside a fauit
rupture zone) . A "No ImpacY' answer should be explained where it is based on
project-specific factors as weil as general standards (e.g. the project will not expose
sensitive receptors to pollutants, based on a project-specific screening analysis .)
2 . All answers must take account of the whole action involved, including off-site as well
as on-site , cumulative as well as project-level, indirect as well as direct, and
construction as we�l as operational impacts.
3 . " Potentially Significant ImpacY' is appropriate if there is substantial evidence that an
effect is significant. If there are one or more " Potentially Significant ImpacY' entries
when the determination is made, an EIR is required .
4. " Potentially Significant Unless Mitigation incorporated" applies where the
incorporation of mitigation measures has reduced an affect from " Potentially
Significant ImpacY' to a " Less than Significant Impact. " The lead agency must
described the mitigation measures and briefly explain how they reduce the effect to
a less than significant level (mitigation measures from Section XVII , " Earlier
Analyses , " may be cross-referenced) .
5 . Earlier analyses may be used where, pursuant to the tiering, program EIR, or other
CEQA process , an effect has been adequately analyzed in an earlier EIR or
negative declaration . Section 15063 (c) (3) (D) . Earlier analyses are discussed in
Section SVII at the end of the checklist.
6. Lead agencies are encouraged to incorporate into the checklist references to
information sources for potential impact (e .g. general plans, zoning ordinances) .
Reference to a previously prepared or outside document should, where appropriate,
include a reference to the page or pages where the statement is substantiated. A
source list shouid be attached , and other sources used or individuals contacted
should be cited in the discussion .

Existing Conditions:
a. The project site is located within the General Plan land use designation of Professionai Office (OP). This land use
designalion provides opportunity for the establishment of office-based working environments for general professional, and
administrative offices, as well as support uses. The proposed project is for an office building and could support the listed
types of office use listed; however future tenants are not known at this time. Each future tenant will be reviewed on a case-
by-case basis to determine the type of required application . Therefore, the proposed project is consistent with the General
Plan land use designation for the project site.
The project site is located within the Commercial-Manufacturing-Billboard Exclusion-Unilaterai/Contract (C•M-BE-U/C) Zo�e.
This zone allows for a variety of land uses by right and with a Conditional Use Permit. The land uses contemplated within
this classification includes but are not limited to the following: general professional, administrative office, research and
development, light manufacturing , medical offices and clinics, commercial retail, restaurants, hotels, physical fitness centers
and government services. Other ancillary and support uses such as day care facilities, gymnasiums, dry cleaning services,
and automobile rental and leasing agencies are permitted. This zoning classification encourages uses that can benefit the
community in many ways including sales tax revenues and attracting an employee base with additional buying power. The
potential use fit into the referenced zoning criteria and is not in conflict with the zoning.
b. The City of Diamond Bar does not have a habitat conservation plan or natural community plan for the project site.
Additionally, the project site was mass graded as a part of the overall grading for Gateway Corporate Center. Therefore, the
proposed project is not in conflict with an applicabie habitat conservation plan or �aturai community plan.
c. The proposed project is an office building that can be utilize for land uses specified above in Item a., which is consistent with
the General Plan, Zoning, Gateway Corporate Center Design Guidelines and existing uses within Gateway Corporate
Center. Therefore, the proposed project is compatible with the existing land uses in the vicinity.
d. City of Diamond Bar does not have any agricultural resources or operations.
e. The proposed project is a vacant lot located within and existing corporate center. The zoning, General Plan land use
designation and Gateway Corporate Center Design Guidelines do not plan for low-income or minority communities within
the corporate center. The proposed project is consistent with the uses within the corporate center. Therefore, the proposed
project wiil not disrupt or divide the physical arrangement of an established communiry including low-income or minority
communities. '

Existing Conditions:
a. The proposed projectis a vacantlotlocated within an established corporate center. Therefore, the proposed project will not
displace numbers of people, necessitating the construction of replacement housing eisewhere.
b. The proposed project site is a vacant, graded lot with a buildable pad and infrastructure within the corporate center, zoned
for commercial-manufacturing development, consistent with the policies presented in the General Plan and standards
presented in the Development Code. The proposed office building, approximately 25,000 square feet) is considered small-
scale compared to many of the existing. building within the Center. When the Center was reviewed by Los Angeles County,
it was expected that the site would be developed. So infrastructure was pianned and instail in anticipation of development.
Therefore, it is not expected that the proposed project will induce substantial growth in an area either directiy or indirectly by
proposing a new business or by the extension of roads or other infrastructure.
c. The proposed project will be located within an existing corporate center. As such, it will not dispiace substantial numbers of
existing housing, necessitating the construction of replacement housing elsewhere.

Existing Conditions : '
a. , b. No portion of the City has been identified as in an Alquist-Priolo Special Studies Zone. The closest fault is the Diamond Bar
Fault, which is described as a "small inactive local faulY'. Historically, there is no record of any eaRhquake with an epicenter
in Diamond Bar of its Sphere of Influence, and no significant movement has ever been recorded for the Diamond Bar fault.
The project area is bound on the north by the San Gabriel Mountains, on the west and south by the Whittier Fault and
Elysian Fault and to the east by the Central Avenue-Chino Fault. The project site is located in highly seismic Southern
California region within the influence of several fault systems that are considered to be active or potentially active.
Therefore, it is anticipated that the project site will periodically experience ground acceleration as the result of small to
moderate magnitude earthquakes. However, faults identified by the State as being either active or potentiaily active are not
known to be present on-site. The site is not located within the State of California designated Earthquake Fauit Zone; nor is
the site located within a Seismic Hazard Zone . The proposed project lies within Seismic Zone 4. The proposed office
building will be designed in accordance with the latest edition (1998) of Uniform Building Code. Therefore, likelihood of fault
rupture is limited.
c.-f. Liquefaction occurs when loose, saturat�d sandy soils are subjected to strong shaking resulting from earthquake motions.
The sands typically lose a portion or all of their shear strength and regain strength sometime after the shaking stops. Soil
movements (both vertical and lateral) have been observed under these conditions due to consolidation of the liquefied soiis
and the reduced shear resistance of slopes. The project site is generally underlain by inter-bedded fine-grained and coarse-
grained soils which contain a high percentage of fines that have been placed as compacted, e�gineered fi��. Considering
the anticipated groundwater depths beneath the site and the type of soiis encountered on-site, it is anticipated that the
liquefaction potential of the underlying materials is very low. It is anticipated that the project site is generally satisfactory for
the proposed project based on a report previously done for a similar project at the subject site. However, the appiicant will
be required to submit a soils report for the City's review and approval address this specific project prior to the issuance of
any City permits. The applicant will be required to implement measure prescribe in the report to the satisfaction of the City.
The closest reservoir is the � Eldertree Reservoir, approximately one mile, by direct route, in a southwesteriy direction. If
seiche occurs, it will not affect the project site. Additionally, the project is not located near any volcanic mountain regions.
There are no large bodies of water in close proximiry to the project site.
g. According to the soils report, the project site is believed to have a medium to high expansion potential. Expansive soils are
characterized by their ability to undergo significant volume change (shrink or sweli) due to variations in moisture content.
Changes in soil moisture content can result from rainfall, landscape irrigation, utility leakage, roof drainages perched
groundwater, drought, or other factors and may cause unacceptable settlement or heave of structures, concrete slabs, or
pavements. Depending on the e�ent and location below finished sub-grade, these soils could have a detrimental effect on
the proposed project. Therefore, it is recommended that additional testing on the project site occur and the soils report
included recommendations for medium expansive potential depending on the test resuits.

Source #s: General Plan, p. IV-4, Fig. IV-2; MEA, p. II-C- 1 et seq.;
Existing Conditions:
a. Development of the project site will reduce pervious surfaces thereby increasing surface runoff. Runof( will be directed from
on-site drainage devices to off-site drainage devices that are designed to accommodate project site runoff. The impacts
associated from the increased runoff are expected to be insignificant. Additionaily, as a project condition of approvai, a
hydrology study shall be required for the Ciry's review and approval. Furthermore, the project will be required to compiy with
_ the appropriate recommendation within the report.
b. The project site is not located within a flood hazard area and adequate drainage devices have been incorporated into the
drainage plan Gateway Corporate Center, as well as the proposed project. Therefore, the proposed project is not expected
to expose people or properry to water related hazards.
c. The proposed project is required to comply with the National Poilutant Discharge Elimination System (NPDES) permit
requirements and incorporated the appropriated Best Management Practices (BMP's) and Standard Urban Storm Water
Mitigation Plan requirements in order to prevent pollution by reducing potential poliutants at the source. Therefore, it is not
expected that the proposed project will violate any water quality standards.
d. ,e. No body of water exists around or near the project site or in the City of Diamond Bar.
f. Due to the proposed projecYs small-scale changes in the quantity of ground waters either through direct additions or
withdrawals, or through interception of an aquifer by cuts or excavations or through substantial loss of groundwater recharge
capability is not expected to occur.
g. Because of this proposed projecYs small size, it wili not effect the direction or rate of flow of groundwater.
h . Due to the discussion above in item c, groundwater quality may be impacted by the proposed smali-scale development, but
its extent is likely to be minimal.
i. The construction of one office building in an urbanized area is not considered to cause a substantial reduction in the amount
of groundwater for public water supply. Additionally, groundwater is only utilized for reclaimed water suppiy.
j. The proposed project is within an existing corporate center. Therefore, it will not place housing within a 100-year fiood
hazard area as mapped on the Federal flood hazard Boundary or fiood Insurance Rate Map or other flood hazard
delineation map or place within a 100-year flood hazard area structures which wouid impede or redirect fiood flows.

Existing Conditions :
a.-d. Air quality may be affected during grading operation; however, it is not expected to be significant with procedures that
wiil be implement to reduce air emissions. Additionally, such emissions are not expected to exceed those listed within
the SCAQMD Air Quality Handbook. Tables 9- 1 and 9-7 are screening tables for operations and construction of
specified primary land uses. Pursuant to the tables and significant thresholds listed on page 6-2, an office building under
96 ,220 square feet will not have a significant impact on air quality in relationship to operations; and an office building
under 559 ,000 square feet will not have a significant impact on air quality in relationship to construction. The proposed
project is requesting approval for 25,000 square feet. Therefore, it is not anticipated that the proposed project wili conflict
with or obstruct the implementation of the applicable air quality plan ; expose sensitive receptors to pollutants; create
objectionable odors; violate air quality standards or contribute substantially to an existing or projected air quality
violation ; or result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-

Existing Conditions:
a:c. The applicant has submitted a Traffic Impact Analysis Report prepared by Linscott Law & Greenspan dated October 21 ,
2002 the City's review and approval. The report reviewed: Site accessfinternal circulation; existing year 2002 traffic counts;
estimated project traffic generation/distribution/assignment; estimated cumulative project traffic generation/distribution
assignment; AM/PM peak hour intersection capacity for existing and future conditions without and with project traffic; and
Key Intersections: Brea Canyon Road at Goiden Spri�gs Drive; Gateway Center Drive at Golden Springs Drive; Copley '
Drive at Golden Springs Drive; and Golden Springs Drive at Grand Avenue. The resuits of the study indicates that: the
proposed project will not have a significant impact on the four key intersections studied; the project driveway wiil be able to
accommodate ingress and egress traffic without undue congestion; the approximate throat length of 50 feet at the project
driveway is sufficient for storing potential queuing vehicles; the on-site circulation layout is adequate; and curb retum radii '
are adequate for small service/delivery trucks, as well as trash trucks. However, the City's traffic engineer, Warren Siecke,
has reviewed the traffic impact analysis and site access evaluation report. It is required that the applicant address Mr.
Siecke's comments and concerns. After the applicant addresses Mr. Siecke's comments and concerns and the results is
traffic impacts, the applicant will be required to correct traffic impacts and/or pay their 'Yair share" towards mitigation of said
impacts to the satisfaction of the Public Works Director, prior to issuance of Certificate of Occupancy. However, after
addressing the comments and concems, the proposed project may not have a significant impact as referenced in the traffic ',
impact analysis report prepared by Linscott Law & Greenspan. '
d. The proposed office building is approximately 25,000 gross square feet and 23,250 net square feet. Pursuant to the City
adopted Gateway Corporate Center Design Guidelines, one parking space is required for each 250 square feet of net floor
area of general office use. Therefore, 93 parking spaces are required and provided. As a result, it is anticipated that the
proposed project will provide adequate on-site parking. �
e. Due to the proposed projecYs small•scale, it is not anticipated that the proposed project will exceed, either individually or
cumulatively, a level of service standard established by the County congestion management agency for designated roads
and highwaya
f. The proposed project's design is consistent with the General Pian's goals, objectives and strategies supporting circulation
and transpor�ation. Therefore, it is not anticipated that the proposed project will confiict with adopted policies, plans, or
programs supporting alternative transportation.
g. No rail, waterborne, or air traffic facilities or operations are in the vicinity of the proposed project. Therefore, the project will
not impact these facilities or operations.

Existing Conditions :
a.-e. The proposed project is located within an existing corporate center approved by los Angeles County and completed by 1986. The
project site was mass graded as part of the overall grading for the corporate center. The mass grading also incorporated the buiidable
pad for the project site. Currently, the pad area is free of vegetation with the exception of moderated weed growth. The project site's
descending slopes are heavily vegetation with ornamental trees and bushes planted by the corporate center as part of its landscape
plan, As a result, it is anticipated that the project site does not contain species identified as a candidate, sensitive or special status
species in local or region plan, policies, or regulation, or by the California Department of Fish and Game or U.S. Fish and Wildlife
Services or riparian habitat and federally protected wetlands as defined by Section 404 Ciean Water Act, or other sensitive natural

MEETING DATE : ' December 10 , 2002
CASEiFILE NUMBER: Development Review No. 2002-32
APPLICATION REQUEST : A request to operate a restaurant within an existing 1 , 200
square feet retail shopping center suite
PROPERTY LOCATION : 333 Diamond Bar Boulevard
PROPERTY OWNER: DBV Star LLC , P. O. Box 5156 , Diamond Bar, CA 91765
APPLICANT: DPC Productions Inc. , 1949 Baltar Street, Canoga Park,
CA 91306
BACKGROUND :
The property Owner, DBV Star LLC , and Applicant, DPC Productions Inc . , request
approval to operate a restaurant within an existing 1 ,200 square feet retail shopping center
suite . The Application does not include alcoholic beverages , outdoor dining , and/or
entertainment. Should the OwnedApplicant wish to include any of these uses , a Minor or

Bar Village , at the northwest corner of Diamond Bar Boulevard and Golden Springs Drive .
The suite's address is 333 Diamond . Bar Boulevard .
The site's Generai Pian Land Use designation is General Commercial (C). The zoning
designation is Community Commercial-C-2 Zone. The proposed Application is a service
commercial use and consistent with the General Plan and Zoning .
Ge �erally, the following zones surround the project site: to the north is the Regional
Commercial (C-3 ) Zone; to the south is the Multipie Residence (R-3- 1 U ) Zone and Lorbeer

REVIEW AUTHORITY
Per the City's Development Code, Section 22 .48 .020 , Deveiopment Review is required for
projects that involve a substantial change or intensification of land use (e.g. the conversion
of an existing structure to a restaurant). The C-2 zoning designation pe�mits a restaurant
use by right. However, the existing retail suite is proposed as a restaurant, which requires
- more parking spaces than the former use. Also, the proposed restaurant is anticipated to
generate more activity at the project site.
Development Review is a discretio�ary review p�ocess, which allows the whole project area
to be reviewed for possible improvements . The Planning Commission is the review
authority.
The purpose of the Development Review process is to establish consistency with the
General Pian through the promotion of high aesthetic and functional standards to
complement a�d add to the economic, physical , and social chasacter of the City. The
process will also ensure that new development and intensification of existing development
yields a pieasant living , working , or shopping environment and attracts the interest of
residents, workers , shoppers and visitors as the result of consistent exemplary design . The
Citys Design Guidelines and City's Development Code standards are used to promote
development that respects the physical and environmental characteristics of the community
and the site .
ANALYSIS :
DEVELOPMENT REVIEW
. Tenant Improvemenfs
The proposed restaurant will occupy a 1 ,200 square feet suite. Approximately 400 square
feet of gross floor area wilf be utiiized for patrons and 800 square feet of gross floor area
wiil be utilized for the service area . The applicant proposes to make only interior tenant
improvements . No square footage will be added to the restaurant structure and as a result,
its exterior physical appearance will be the same .
+ Hours of Operation/Number of Employees
The new restaurant wil4 be open from 11 :00 a .m . to 11 :00 p . m . , daily. The restaurant is
expected to have 2-3 employees .
• Fast Food Menu
The proposed menu is attached . Items include beverages and Chinese deli items.
2
• Parking
Pursuant to Code , restaurants require one parking space per each 75 square feet of gross
floor area for patrons , plus one parking space for each 300 square feet of service area .
The proposed restaurant contains approximately 400 square feet of gross floor area for '
patrons and 800 square feet of gross floor area for service. As a resuit, a minimum of eight
(8 ) parking spaces is required for the proposed restaurant.
A Conditional Use Permit for this location was approved in November for the Curves .
Additionally, a parking study was conducted and according to staffs physical count at that
time , the existing shopping and professional center's lot with landscaping has
approximately 397 parking stalis. The proposed project will occupy an existing vacant unit
