Gilead Sciences, Inc.

Supplement to the Community Development Department General Application Gilead Campus Expansion Project
Updated: June 6, 2025

To: Foster City Community Development Director Sofia Mangalam

Gilead Sciences, Inc. (“Gilead”) presents this formal application for the proposed Gilead Campus Expansion Project (“Project”) in the Chess Drive/Hatch Drive area (“Property”) in the City of Foster City (“City”).

This letter serves as a supplement to the City’s Community Development Department General Application form. It is intended to clarify, expand upon, and formally submit Project details for the City’s review and entitlement processing. As of June 6, it has also been modified per City feedback.

Prior to this formal application, Gilead submitted a Preliminary Review application on February 14, 2025. (File No: PR2025-0003.) City staff provided formal feedback in writing on April 8, 2025, following internal review and a meeting of an Interdepartmental Evaluation Committee (IDEC) conducted with Gilead on March 5, 2025. This letter, as well as other relevant Project materials, incorporates and responds to that feedback. Additionally, Gilead is transmitting, concurrent to this formal application, a comprehensive response log to the City’s Preliminary Review feedback. This response log outlines how Gilead has addressed each comment and request for clarification raised during the Preliminary Review process.

This supplement provides the following sections: (1) Background, (2) Project Description, (3) Land Use Consistency, (4) Requested Entitlements, (5) California Environmental Quality Act (“CEQA”) Review and Environmental Assessment Form, (6) Submittals for Formal Application, and (7) Project Implementation Timeline.

1. Background
In 2005-2006, the City initiated a study of the Property in or der to promote new business development, especially biotechnology and high technology companies. In response to the study, the two property owners, Northwestern Mutual Life and Sea Cliff Prope rties (the “Original Owners”), proposed the Chess-Hatch Master Plan project (the “O riginal Project,” RZ-07-002 and DA-09-002), with the following:
 On November 2, 2009, the City certified the Final EIR (SCH #2008122065, EA-07-001) and adopted a Mitigation Mon itoring and Reporting Program for the Original Project.

Additionally, on November 2, 2009, the City ame nded its General Plan to designate the Property as Chess/Hatch Office Research.
 On January 24, 2011, the Original Owners submitted a proposal to revise the Original Project to substitute five multi-story structures a nd one single-story struct ure for the three multi- story structures previously proposed. On August 19, 2013, the City adopted the Addendum

9.1 Attachment 2 - Project Description

465

dated February 19, 2013 as an adequate e nvironmental document pursuant to CEQA via Resolution No. 2013-64.
 On September 3, 2013, the City approved a Master Development Agreement to develop the Chess Hatch Master Plan on the Chess-Hatc h Property via City Or dinance No. 574. The Master Development Agreement was recorded with the County of San Mateo on September 11, 2014 as Document No. 2014-082572, with an initial term of five years.  Additionally, on September 3, 2013, the City amended its zoning map for the Chess-Hatch Property, changing the zoning designation to CM/PD (Commercial Mix/Planned Development). It also approved a General Development Plan to allow up to 800,000 square feet of office, biotechnology, or research and development uses on the Chess-Hatch Property via City Ordinance No. 573.
 On April 17, 2014, the City’s Planning Commission approved Use Permit/Specific Development Plan (UP-13-004 and EA-07-001B) to allow the demolition of nine office buildings, comprising 146,000 square feet of development, and construction of 600,000 square feet of office devel opment area and up to 5,000 square feet of business supporting use in two towers and a connector building, and construction of tw o multi-story parking garages.
 On September 1, 2015, the Original Owners assigne d their interest as Developers in the Development Agreement to Gilead. On Janua ry 8, 2019, Gilead and the City signed a Memorandum of Extension, and the Initial Term of the Ma ster Development Agreement was extended to expire on September 7, 2024.

Ultimately, the Original Project was never constructed. On September 7, 2024, both the Use Permit/Specific Development Plan and the Master Development Agreement expired. The original nine office buildings, comprising 146,000 square feet of existing development, remain in use on the Chess-Hatch Property.

2. Project Description
Gilead proposes a new Project fo r the Property to support its long-te rm expansion in the City and fulfill the original vision for the Property. The Project builds on Gilead's integrated campus operations and aims to enhance Gilead’s research capabilities to support its growing pipeline.

The Gilead Campus Expansion Project proposes phased demolition of twelve existing office buildings (totaling 191,507 square feet
1), together with the constr uction of up to a maximum of 800,000 square feet of biotechnology or research and development us es, in addition to a single, standalone, multi-story parking garage.

Similar to the Original Project, the Project would proceed in tw o phases, as described below and depicted in concept in the attached Project Plans.

1 Note that the square footage of existing buildings is approximate.

9.1 Attachment 2 - Project Description

466

A. Phase One
In Phase One, eight of the tw elve existing office buildings, comprising approximately 123,536 square feet of development, would be demolished and a two-story building of up to approximately 200,000 square feet would be constructed.

In Phase One, the two-story building would be supported by surface parking. Based on Gilead’s anticipated parking needs and integration wi th its existing campus Transportation Demand Management/Transportation Systems Management (“TDM/TSM”) program, the parking proposed would require approval of a reduction in parking requirements under the provisions of Zoning Code Section 17.36.060. Gilead will submit a Parking Impact Analysis Report with the formal application to support the need for reduced parking.

The landscaping around the existing buildings w ould be removed and replaced, although some of the landscaping and trees would be retained until Phase Two is complete. Vehicular access to the property would be from Chess Drive. There are three driveways accessed from Chess Drive.

Additionally, a loading area is planned. A service road/fire lane encircles most of the site, providing emergency vehicle and service access to the rear of the property.

B. Phase Two
As shown conceptually in the attached Projec t Plans, Phase Two would consist of additional buildings up to a maximum of approximately 600,000 square feet, together with a multi-story parking garage. The new building would replace so me of the surface parking used in Phase One.

The remaining four existing build ings (approximately 67,971 square feet) would be demolished, and a multi-story parking garage would replace them, providing all of the necessary parking for the entire site.

3. Land Use Consistency
The Property is designated as Chess/Hatch Office Research in the Genera l Plan. The Property is zoned as CM/PD (Commercial Mix/Planned Devel opment). The Property is also subject to the Chess Hatch General Development Plan adopted in 2013.

The Project has been designed to comply with the General Plan and Zoning. Attachment A provides an initial consistency analysis with all applicab le General Plan designati ons and Zoning district regulations.

The Chess Hatch General Development Plan contains limitations and authorizations that are specific to the Original Project. The Chess Hatch General Development Plan requires revisions to allow for the Gilead Campus Expansion Pr oject. Notably, the new Project pr oposes to remove standalone office space as an approved use under the Gene ral Development Plan. However, there may be ancillary office space that is in support of biot echnology uses, while standalone office is proposed to be removed as a permitted us e within the General Development Plan. Similarly, other changes are intended to modernize the General Development Plan to bring it into conformance with the new Project. Attachment B provides a draft redline and annotations of the proposed revisions to the General Development Plan for the City’s review and feedback.

9.1 Attachment 2 - Project Description

467

The proposed revisions to the General Development Plan repr esent minimal adjustments to modernize outdated provisions ra ther than substantive policy changes. The existing General Development Plan was crafted in 2013 for the Original Project , which had a different design approach and site layout than the current proposa l more suited to the office product that was in demand at the time. The prescriptive language in the current General Development Plan references specific exhibits and design parameters that are no longer applicable to Gilead's proposed development approach, creating unnecessary constraints that serve to impede the Property’s development.

Provisions in the existing General Development Plan contain outdated references to expired agreements. The Master Development Agreement expired in September 2024, and multiple sections of the General Development Plan reference this expired agreement as the basis for ongoing obligations. These references create increased uncer tainty as they point to documents that are no longer operative.

The existing General Development Plan also contains overly prescriptive design standards that were tailored to a specific architectural approach contemplated in 2013. While the fundamental development parameters — including the 800,000 square foot maximum, height limits, and FAR requirements — remain unchanged, the specific layout requirements and design mandates in the current General Development Plan are unnecessa rily restrictiv e and prevent Gilead from implementing a more current design that still meet s all of the City's redevelopment goals for the Property.

The proposed amendments update outdated refere nces, remove provisi ons tied to expired agreements, and provide appropriate flexibility in site design while maintaining the substantive planning that the City intended. These revisions enable implementation of the Project while ensuring continued compliance with the City's vision for high-quality development on the Property.

4. Requested Entitlements

The following entitlements are anticipated to be required:
 an Amendment to the General Developm ent Plan for Chess-Hatch Master Plan for the Property.
 a Vesting Tentative Parcel Map for the Property. (The Project proposes the creation of four or fewer parcels and therefore qualifies under the Subdivision Map Act for a Vesting Tentative Parcel Map.)
 a Use Permit/Specific Development Plan for only Phase One. (As in the Original Project, a Use Permit/Specific Development Plan would be separately submitted for Phase Two in the future.)

For clarity, Gilead proposes to amend the existing General Development Plan that already applies to the entire Property, regardless of phasing. The existing General Development currently contemplates a project in two phases; similarly, the Project also proposes a project in two phases,

9.1 Attachment 2 - Project Description

468

modified to reflect a new design. Just as before with the originally approved Chess-Hatch project, Gilead is requesting a Use Permit/Specific Development Plan for only Phase One at this time.

Gilead will apply for Phase Two in the future.

5. CEQA Review and Environmental Assessment Form

The Background section above describes the CEQA review that has occurred to date. The proposed Project is similar in nature compared to the Original Project, and the Project is within the envelope of what was studied within the CEQA documents for the Original Project. Therefore, Gilead does not anticipate the Project to result in new significant impacts. Gilead has retained Lamphier- Gregory to assist with the preliminary environmental review and submitted initial recommendations for discussion with the City as a Memo on CEQA Compliance in conjunction with the Preliminary Review. Gilead prepared this solely for the City’s information and understands that the City will use its independent discretion to complete the formal CEQA analysis as Lead Agency. The memo on CEQA compliance will not accompany the formal application.

Gilead is enclosing the Environmental Assessment Form as requested by the City with regard to CEQA.

6. Submittals for Formal Application
Gilead is submitting a formal a pplication and materials to support the requested entitlements, as described in Section 4:
 Community Development Department General Application Form and Application Fee  Response Log to Preliminary Review (File No: PR2025-0003) Letter (received by Gilead on April 8, 2025)
 Current Preliminary Title Report
 Project and Land Use Tables

17.36.060(B) Off-street parking requirements in a PD district.

When the planning commission has determined
that conditions allowing a deviation from the
total number of required off-street parking
spaces are present, the planning commission
may grant such deviation as deemed
appropriate, based upon the following
information provided by the applicant:

1. A parking analysis discussing all impacts
resulting from the deviation from usual off-
street parking requirements, including
alternative parking designs or strategies
considered, and why they were deemed
infeasible, if applicable, and alternatives for
mitigating negative impacts identified.

Consistent. Gilead will provide a Parking
Impact Analysis Report that will describe the
impacts of the proposed deviation from
standard off-street parking requirements in the
context of Gilead’s overall TDM strategy for
its integrated campus. This Report includes
consideration of alternative parking designs
and strategies, and explains why these
alternatives were deemed infeasible. It will also
include a list of TDM measures.

2. The parking analysis may include a clear,
documentable rationale describing how and
why the proposed parking will work at the
given site and specifically identifying where it
has been successfully used in other comparable
projects and cities, and/or any other
information as requested by staff and the
plannin
g commission.

Consistent. Gilead will submit a Parking
Impact Analysis Report and the required TDM
Plan and TDM Checklist, drawing from the
example of its Integrated Campus nearby in the
City of Foster City.

Chess Hatch Design Principles Document, dated 06.05.13, prepared by Valerio Dewalt Train and Associates.

Maximum FAR: 1.55 Consistent. Gilead proposes a Project in two phases; upon full build-out, the Project’s FAR
will be approximately 1.55.

Maximum Building Height: 150 feet to 190
feet
Consistent. The Project as proposed does not
exceed this maximum building height.

Lot Coverage: Maintain significant public
open and green space, with the upper limit of
lot coverage governed by the success of the
design.

Consistent. Gilead proposes significant public
open and green space.

Context: Surfaces should not be monolithic,
they should have a sense of detail. Solids and
glass should be roughly equal, and the
composition balanced with an emphasis on the
horizontal.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with surfaces
that have a sense of detail.

Site Coherence: The building should mark the
corner with a visual icon, and buffer pedestrian
zones and entries from freeway. The building
shape should serve to help transition from high
to the low scale of the neighborhood.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with buffered
pedestrian zones, a transition from high to low
scale, and a visual icon at the corner.

Massing: There should be logic to how the
building meets the ground and the sky…and
what is in between.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with logical
massing considerations.

Building Form: The building should be solid
and rectangular in form so that the floor plates
Consistent. Gilead proposes buildings that will
adhere to these design principles, with

9.1 Attachment 2 - Project Description

476

are similar in size. Any features such as curves,
angles, arcades and cantilevers should act as
punctuation to the overall design.
rectangular building forms and similar-sized
floor plates.

Integration: Parking should be part of the
overall building design, and signage should
never be an afterthought.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with parking
integrated into the overall building design and
signage thoughtfully considered.

Landscape: The open space around the
building should create a sense of place and
welcome people for momentary experiences. It
should provide a place for people to sit and
gather.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with open
spaces around the buildings that create a sense
of place and provide areas for people to sit and
gather.

Environmental Logic and Sustainability:

The overall design should respond to the
environment. Design should be driven by using
materials and methods that are low impact.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with a focus
on using low-impact materials and methods to
drive sustainability in the design.

Relationship between Materials: There
should be a contrast between the natural
materials used and the highly finished ones.

There should be roughly equal parts of both in
the final design. All materials should be
interpreted in their most natural color.

Consistent. Gilead proposes buildings that will
adhere to these design principles, with contrast
between natural and finished materials and an
emphasis on natural color.

SUBJECT: Gilead Sciences Campus Expansion Project & New Chess Facility – Preliminary Transportation Impact Study Results

1. Background Information
This technical memorandum summarizes the results of a transportation impact analysis (TIA) for a proposed Gilead Campus Expansion Project, including a phased development plan on the Chess Hatch Property (the “Project”) in Foster City (the “City”), California. The Project site is located west of State Route 92 (SR 92), north of Foster City Boulevard, east of Chess Drive, and south of a lagoon of Foster City Lake in an area known as the Chess/Hatch Office Research Site (seeFigure 1). The Project would be completed in two phases. Phase I would demolish eight existing office buildings and construct up to approximately 200,000 square-foot biotechnology research and development (R&D) building with surface parking to be used by Gilead Sciences (the “Project Applicant”). Phase II would construct an additional up to 600,000 square feet of space to be used for biotechnology R&D by the Project Applicant, together with a multi-story parking garage. Phases I and II would equate to a total of up to 800,000 square feet for biotechnology R&D and would be considered full buildout of the Project.

This TIA identifies potential impacts associated with the Project based on standards and methodologies established by Foster City and by the State of California Governor’s Office of Planning and Research (“OPR”).

The study includes evaluations of traffic operational conditions during the a.m. and p.m. peak hours for six study intersections. The study additionally addresses the potential transportation effects of the proposed Project to assist the City with Project planning and with the identification of potential conditions of approval of the Project.

2. Study Methodology
This section describes the study area and the specific locations on the local transportation network that were evaluated during the analysis. This section additionally describes the metrics and thresholds used to determine if Project effects on the local transportation network are inconsistent with local standards and plans.

2.1 STUDY AREA
A study area establishes specific locations where, or boundaries in which, a transportation impact analysis is conducted. Study areas allow transportation analyses to identify critical points on the local roadway network that might experience acute effects from a proposed development while avoiding unnecessary study of locations that would experience little to no effects from the proposed development.

The study area for this traffic study was determined based on the estimated peak hour trips added by the project to the nearby study intersections. The majority of the project trips are expected to be added to intersections located between the proposed project and the SR-92/Chess Drive/Metro Center Boulevard interchange. The following study intersections are listed below inTable 1.

Table 1: Study Intersections

1 Foster City Boulevard & Chess Drive / Vintage Park Drive Signal 2 Vintage Park Drive & Chess Drive Signal
3 SR 92 Westbound Ramps & Chess Drive Signal
4 Foster City Boulevard & Chess Drive Signal
5 SR 92 Eastbound Ramps & Metro Center Boulevard Signal 6 Foster City Boulevard & Metro Center Boulevard / Triton Drive Signal

2.2 STUDY SCENARIOS
In accordance with discussions with the Project Applicant, this traffic study evaluates the following traffic scenarios:
l Existing Conditions – This scenario evaluates traffic conditions in the study area with existing traffic volumes. Existing volumes are from approved traffic studies for other development projects nearby the study area and were collected in October 2017 and May 2019. They represent traffic conditions from the pre-pandemic era, which typically have higher traffic volumes than the post-pandemic era. Existing roadway geometries and traffic controls were additionally used for this scenario.
l Existing plus Phase I Project Conditions – This scenario evaluates traffic conditions in the study area with Existing Conditions traffic volumes plus traffic associated with Phase I of the Project.

kimley-horn.com 4637 Chabot Drive, Suite 300, Pleasanton, CA 94588 925 398 4840 l Cumulative Conditions – This scenario evaluates traffic conditions in the study area with traffic volumes projected to the horizon year of 2040.
l Cumulative plus Full Project Buildout Conditions – This scenario evaluates traffic conditions in the study area with Cumulative Conditions traffic volumes plus traffic associated with full buildout of the Project (Phase I plus Phase II).

2.3 STUDY METRICS
Transportation impacts related to the proposed Project were evaluated for both compliance with applicable regulatory documents and environmental significance as defined in the California Environmental Quality Act (CEQA). In accordance with OPR’s2018 Technical Advisory on Evaluating Transportation Impacts in CEQA1 (the “Technical Advisory”), a quantitative vehicle miles traveled (VMT) assessment is the preferred methodology for determining the environmental significance of transportation impacts of development projects under CEQA. Effective July 1, 2020, vehicular delay on roadway segments and intersections qualitatively measured using the level of service (LOS) metric can no longer be used to determine the environmental significance of transportation impacts of development projects for CEQA purposes. However, the OPRTechnical Advisory does not exclude the use of LOS when determining consistency with plans and standards of local jurisdictions and agencies such as Foster City.

2.3.1 Vehicle Miles Traveled
VMT is a metric that quantifies vehicular travel volumes on transportation facilities. A quantity of 10 VMT could equate to one vehicle traveling 10 miles or 10 vehicles traveling one mile.

Senate Bill 743 of 2013 (“SB 743”) directs OPR to establish specific criteria for determining the significance of transportation impacts of development projects for CEQA purposes. The OPRTechnical Advisory provides such specific criteria but additionally allows local jurisdictions and agencies the discretion to set or apply their own thresholds of significance. As the City of Foster City has not established its own VMT standards, this traffic study defaults to the standards provided in the OPR Technical Advisory.

The OPR Technical Advisory contains the following criteria to screen out projects that are presumed to have a less-than-significant impact and would not require a full VMT analysis:
l Is a residential or office land use located near transit stations or stops, subject to applicability. l Is located within areas with low VMT.
l Is a small, local-serving land use that would generate or attract fewer than 110 trips per day. l Is an infill affordable housing land use.

491

kimley-horn.com 4637 Chabot Drive, Suite 300, Pleasanton, CA 94588 925 398 4840 Based on the above criteria, the proposed Project would not be screened out and requires a full VMT analysis.

2.3.2 Intersection Level of Service
Although CEQA now recognizes VMT as the primary analysis methodology for transportation impacts, it does not preclude local agencies from using LOS to establish operational standards for local roadway networks.

The LOS of an intersection is a qualitative measure used to describe operational conditions. LOS ranges from “A” (best), which represents minimal delays experienced by roadway users, to “F” (worst), which represents heavy delays experienced by roadway users and a facility that is operating at or near its functional capacity. LOS for this study were determined using methods defined in the Transportation Research Board’s Highway Capacity Manual, 7 th Edition (HCM 7 th Edition ). The HCM 7 th Edition includes procedures for analyzing side street stop controlled (SSSC), all-way stop controlled (AWSC), and signalized intersections. The SSSC procedure defines LOS as a function of average control delay for the worst minor street movement or major street left-turn. Conversely, the AWSC and signalized intersection procedures define LOS as the average control delay of all approaches weighted by volume.

Table 2 and Table 3 relate the operational characteristics associated with each LOS category for unsignalized and signalized intersections.

Table 2: Unsignalized Intersection Operational Characteristics Definitions LOS Delay
(sec/veh) Descriptions
A 0-10 Little or no delay
B >10-15 Short traffic delays
C >15-25 Average traffic delays
D >25-35 Long traffic delays
E >35-50 Very long traffic delays
F >50 Extreme delays potentially affecting other traffic movements in the intersection

(sec/veh) Descriptions
A 0-10
Free Flow/Insignificant Delays: No approach phase is fully utilized by traffic and no vehicle waits longer than one red indication. Most vehicles do not stop at all. Progression is extremely favorable and most vehicles arrive during the green phase.

B >10-20
Stable Operation/Minimal Delays: An occasional approach phase is fully utilized. Many drivers begin to feel somewhat restricted within platoons of vehicles. This level generally occurs with good progression, short cycle lengths, or both.

C >20-35
Stable Operation/Acceptable Delays: Major approach phases fully utilized. Most drivers feel somewhat restricted. Higher delays may result from fair progression, longer cycle lengths, or both. Individual cycle failures may begin to appear at this level, and the number of vehicles stopping is significant.

D >35-55
Approaching Unstable/Tolerable Delays: The influence of congestion becomes more noticeable. Drivers may have to wait through more than one red signal indication. Longer delays may result from some combination of unfavorable progression, long cycle lengths, or high v/c ratios. The proportion of vehicles not stopping declines, and individual cycle failures are noticeable.

E >55-80
Unstable Operation/Significant Delays: Volumes at or near capacity.

Vehicles may wait though several signal cycles. Long queues form upstream from intersection. These high delay values generally indicate poor progression, long cycle lengths, and high v/c ratios. Individual cycle failures are a frequent occurrence.

F >80
Forced Flow/Excessive Delays: Represents jammed conditions. Queues may block upstream intersections. This level occurs when arrival flow rates exceed intersection capacity, and is considered to be unacceptable to most drivers. Poor progression, long cycle lengths, and v/c ratios approaching

1.0 may contribute to these high delay levels.

2.4 THRESHOLDS OF DEFICIENCY
This section discusses the thresholds of deficiencies that apply to the Project.

2.4.1 Vehicles Miles Traveled
The OPR Technical Advisory provides the following VMT significance thresholds for various development projects:
l Residential projects exceeding a level of 15 percent below existing VMT per capita in the city or region may indicate a significant transportation impact. l Office projects exceeding a level of 15 percent below existing regional VMT per employee may indicate a significant transportation impact.

9.1 Attachment 4 - Preliminary Traffic Impact Study Results

493

kimley-horn.com 4637 Chabot Drive, Suite 300, Pleasanton, CA 94588 925 398 4840 l Retail projects that result in a net increase in total VMT may indicate a significant transportation impact.

VMT methodologies typically lump land uses into the above three categories (even if those land uses do not fit the exact definitions of the three categories) based on demographic data and employment- based trip behavior associated with those land uses.

The characteristics of the land uses proposed by the Project would categorize the Project as an “Office” development. Thus, the Project would be considered to generate a significant transportation impact if its expected VMT per employee exceeds a level of 15 percent below the existing regional VMT per employee baseline.

2.4.2 Intersection Level of Service
The LOS analysis included in this study was prepared based on the standards and methodologies established by the City of Foster City. The Foster City General Plan establishes the following operational thresholds for its local roadway network:
l A minimum of LOS C during non-peak hours
l A minimum of LOS D during peak hours
l A minimum of LOS F during all hours at the following intersections:
n Foster City Boulevard & Chess Drive / Vintage Park Drive (Study Intersection 1) n Vintage Park Drive & Chess Drive (Study Intersection 2) n SR 92 Westbound Ramps & Chess Drive (Study Intersection 3) n Foster City Boulevard & Chess Drive (Study Intersection 4) n Foster City Boulevard & Metro Center Boulevard / Triton Drive (Study Intersection 6) The Foster City General Plan does not include guidance for when an intersection is already operating at unacceptable LOS. Therefore, in consistency with other approved TIAs, this study considers Project deficiencies to occur when:
l For facilities that currently operate at an acceptable LOS without the Project:
n The addition of Project-related traffic causes the LOS on a study facility to change from an acceptable LOS under “no Project” conditions to an unacceptable LOS under “with Project” conditions.
l For facilities that currently operate at an unacceptable LOS without the Project:
n A project deficiency occurs if the addition of Project traffic increases the average vehicle delay for a signalized intersection by four (4) seconds or more, or n A project deficiency occurs if the addition of Project traffic increases the average delay for an all-way stop controlled intersection by four (4) seconds or more and the intersection meets the peak hour signal warrant, or
n A project deficiency occurs if the addition of Project traffic increases the highest delayed side-street movement of a stop-controlled intersection by four (4) seconds or more and the intersection meets the peak hour signal warrant.

494

kimley-horn.com 4637 Chabot Drive, Suite 300, Pleasanton, CA 94588 925 398 4840 n For intersections that are allowed to operate at LOS F because they are necessary due to their role as access points to the freeway system, as stated in LUC-F-1 of the Land Use and Circulation Element of the Foster City General Plan, the increases in delay due to Project traffic added would not result in a deficiency.

3. Existing Conditions
This section describes the existing operating conditions of the study intersections prior to implementation of the proposed Project.

Peak hour turning movement counts for Existing Conditions were obtained from an approved traffic study for a development project nearby the study area2.

Existing lane geometries, control types, and signal timings at the study intersections were simulated using PTV Vistro software.

3.1 INTERSECTION LEVEL OF SERVICE
Traffic operations under Existing Conditions were evaluated at the study intersections. The results of the analysis are shown in Table 4.

All study intersections operate at LOS that are consistent with Foster City standards and plans.

4. Existing plus Phase I Project Conditions
This section describes the impacts of Phase I of the proposed Project at the study intersections and the surrounding roadway system. The Existing plus Project Conditions scenario consists of existing traffic volumes and roadway facilities plus new traffic generated by the proposed Project.

The amount of traffic added to the roadway system by the proposed Project is estimated using a three- step process:
l Trip Generation (Section 4.1) – Estimates the amount of traffic added to the roadway network; l Trip Distribution (Section 4.2) – Estimates the direction of travel to and from the Project site; and
l Trip Assignment ( Section 4.2) – Allocates Project-related traffic to specific street segments and intersection turning movements.

4.1 TRIP GENERATION
A trip generation evaluation typically refers to the Institute of Transportation Engineer’s (ITE) Trip Generation Manual, 11th Edition, which is a standard reference used by jurisdictions throughout the country to estimate the trip generation potential of proposed developments.

A trip is defined in the Trip Generation Manual as a single or one-directional vehicle movement with either the origin or destination at a project site. In other words, a trip can be either “to” or “from” the site and therefore, a single visitor to a site is counted as two trips.

Trips are typically calculated from trip rates in theTrip Generation Manual for times of the day and week during which a proposed development’s worst-case transportation impacts on the surrounding roadway network would be expected to occur. These time periods are typically the a.m. peak hour (generally between the hours of 7:00 a.m. to 9:00 a.m.) and the p.m. peak hour (generally between the hours of 4:00 p.m. to 6:00 p.m.) on a typical weekday.

For the purposes of this study, custom trip rates provided by the Project Applicant (rather than those from theTrip Generation Manual) were used to estimate Project-related trips to reflect the unique nature of the proposed land uses. These custom trip rates were derived and utilized in the Gilead Sciences Integrated Corporate Campus Master Plan Subsequent Environmental Impact Report3 (Gilead Campus Master Plan SEIR).

Note that a trip reduction of 23.3 percent was applied to the Project to reflect the implementation of the Gilead Integrated Campus transportation demand management (TDM) program. The TDM program is required to provide a minimum trip reduction of 23.3 percent for the Gilead Integrated Campus. Since the Project is an expansion of the Gilead Integrated Campus, the trip reduction was applied to the 3 Gilead Sciences Integrated Corporate Campus Master Plan Subsequent Environmental Impact Report , LSA, December 2012.

4.2 TRIP DISTRIBUTION & TRIP ASSIGNMENT
Trip distribution is a process of estimating the directions of Project-related vehicular trips. The trip distribution of the Project was developed based on existing travel patterns, knowledge of the study area, and discussions with the Project Applicant.

The trip distribution for vehicles is listed below:
l Three percent to/from the north via Foster City Boulevard l 12 percent to/from the northeast via SR 92
l Six percent to/from the southeast via Foster City Boulevard l Four percent to/from the southeast via Shell Boulevard l Seven percent to/from the south via Edgewater Boulevard l 63 percent to/from the southwest via SR 92
l Five percent to/from the southwest via Fashion Island Boulevard The Project-related trips were assigned to specific turning movements of the study intersections using PTV Vistro software.

4.3 INTERSECTION LEVEL OF SERVICE
Traffic operations under Existing plus Phase I Project Conditions were evaluated at the study intersections. The results of the analysis are shown inTable 6.

All study intersections operate at LOS that are consistent with Foster City standards and plans.

5. Cumulative Conditions
This section describes the operating conditions of the study intersections prior to implementation of the proposed Project during the horizon year of 2040. A horizon year of 2040 was used to be consistent with other approved transportation impact studies.

Peak hour turning movement volumes for Cumulative Conditions were obtained from the same sources of the Existing Conditions peak hour turning movement counts (Section 3). Note that Cumulative plus Project Conditions volumes from the source study are considered Cumulative Conditions volumes in this study.

5.1 INTERSECTION LEVEL OF SERVICE
Traffic operations under Cumulative Conditions were evaluated at the study intersections. The results of the analysis are shown in Table 7.

6.1 TRIP GENERATION
The trip generation process used for Phase I of the Project ( Section 4.1) was applied to the trip generation process for full buildout of the Project. This includes the applications of the same custom trip rates provided by the Project Applicant and the TDM trip reduction of 23.3 percent.

Table 8 shows the trip generation of full buildout of the Project.

Full buildout of the Project would generate approximately 4,976 daily trips, 204 trips (168 in, 36 out) during the a.m. peak hour, and 288 trips (47 in, 241 out) during the p.m. peak hour.

7. Vehicle Miles Traveled
The VMT Estimation Tool developed by the City/County Association of Governments of San Mateo County (C/CAG) as part of its VMT/Greenhouse Gas (GHG) Model Mitigation Program was used for the VMT assessment of the proposed Project.

The VMT Estimation Tool determined the regional baseline of the Project to be 17.41 VMT per employee. A 15 percent reduction of this baseline leads to an upper significance threshold of 14.8 VMT per employee. According to the VMT Estimation Tool, the Project is estimated to generate approximately 16.2 VMT per employee, which exceeds the upper significance threshold by approximately 1.4 VMT per employee or 8.64 percent. The Project would therefore generate a significant transportation impact in the absence of a TDM program.

A TDM agreement between Foster City and the Project Applicant for the Gilead Integrated Campus is required to reduce vehicular transportation impacts of that project by at least 23.3 percent (seeSection

4.1). Application of the Gilead Integrated Campus TDM program to this project, which is a 23.3 percent reduction in Project VMT per employee, would result in a reduced Project VMT per employee of 12.43, which falls below the upper significance threshold of 14.8 VMT per employee. Based on the results of the VMT analysis, with application of the Gilead Integrated Campus TDM program to this site, project transportation impacts would be less than significant.

8. Conclusion
Based on the results of the VMT analysis, with application of the Gilead Integrated Campus TDM program to this site, project transportation impacts would be less than significant.

Based on the results of the traffic analysis, there are no Project deficiencies identified for LOS.
