CALIFORNIA ENVIRONMENTAL QUALITY ACT FINDINGS AND STATEMENT
OF OVERRIDING CONSIDERATIONS FOR THE VALLCO SPECIAL AREA
SPECIFIC PLAN PROJECT
I. INTRODUCTION
The City of Cupertino ("City"), as the Lead Agency under California Environmental
Quality Act ("CEQA"), Public Resources Code Section 21000 et seq., has prepared the
Final Environmental Impact Report for the Vallco Special Area Specific Plan (State
Clearinghouse No. 2018022021) ("Final EIR" or "EIR"). The Final EIR is a project EIR
pursuant to section 15161 of the State Guidelines for implementation of the CEQA
("CEQA Guidelines').' The Final EIR consists of the May 2018 Draft Environmental
Impact Report ("Draft EIR"), the July 2018 Environmental Impact Report Amendment
("EIR Amendment"), the August 2018 Final Environmental Impact Report volume, and
the August 30, 2018, September 11, 2018, and September 13, 2018 Supplemental Text
Revisions to the Vallco Special Area Specific Plan Final Environmental Impact Report.
Pursuant to Public Resources Code Section 21093 and CEQA Guidelines Section 15152,
this Final EIR tiers from the City's certified 2014 General Plan Amendment, Housing
Element Update, and Associated Rezoning EIR (State Clearinghouse No. 2014032007)
("General Plan EIR"). CEQA Section 21093(b) states that environmental impact reports
shall be tiered whenever feasible, as determined by the lead agency. "Tiering" refers to
using the analysis of general matters contained in a broader EIR (such as one prepared
for a general plan or policy statement) in subsequent EIRs or Initial Studies/negative
declarations on narrower projects; and concentrating the later environmental review on
the issues specific to the later project. CEQA Guidelines §15152(a). The General Plan EIR
evaluated, at a program -level and limited project -level, the environmental impacts of
developing the project.
In determining to approve the Vallco Town Center Specific Plane (the "Project," referred
to as the Final EIR as the "revised project"), which is described in more detail in Section
II, below, the Council makes and adopts the following findings of fact and statement of
overriding considerations, and adopts and incorporates into the Project the mitigation
measures identified in the EIR, all based on substantial evidence in the whole record of
1 The State CEQA Guidelines are found in California Code of Regulations, Title 14, Section
15000 et seq.
'Following publication of the EIR, the Project was renamed from Vallco Special Area Specific
Plan to Vallco Town Center Specific Plan.
this proceeding ("administrative record"). Pursuant to CEQA Guidelines § 15090(a), the
EIR was presented to the City Council of the City of Cupertino, and the City Council
reviewed and considered the information contained in the EIR prior to making the
findings in Sections IV to XII, below. The conclusions presented in these findings are
based upon the EIR and other evidence in the administrative record.
II. PROJECT DESCRIPTION
The City undertook a community-based planning process to develop a Specific Plan for
the Vallco Special Area. The proposed Project,, which is described in Section 2.4 of the
Draft EIR as revised by Sections 2.1 (Revised Project) and 6.0 (Text Revisions) of the
Final EIR, is the adoption of the community -developed Vallco Special Area Specific
Plan and associated General Plan and Zoning Code amendments. As defined by
Government Code Section 65450, a specific plan is a tool for the systematic
implementation of the general plan. It establishes a link between implementing policies
of the general plan and the individual development proposals in a defined area.
The project site ("Plan Area") consists of approximately 70 acres, approximately 58
acres of which is currently available for development. The developable area consists of
multiple parcels and is located on both sides of North Wolfe Road, between Vallco
Parkway and Interstate 280 (I-280) on the east side of North Wolfe Road and between
Stevens Creek Boulevard and Vallco Parkway on the west side of North Wolfe Road, in
the City of Cupertino. The locations of the proposed land uses have not been finalized;
therefore, for the purposes of the EIR and these Findings, it is assumed the uses could
be placed anywhere within the site. The Specific Plan identifies three districts — the
Retail/Entertainment Mixed-use District (generally the area south of Vallco Parkway
and to the west of North Wolfe Road), the Neighborhood Mixed-use District (generally,
the areas to the north of Vallco Parkway and to the west of North Wolfe Road) and the
Office Mixed-use District (located north of Vallco Parkway and to the east of North
Wolfe Road). It is expected that more of one use than another may be present in each of
these districts; for example, while more commercial development is expected on the
ground level in the Retail/Entertainment Mixed-use District, the uses on the upper
levels may consist of a mix of the other allowed uses on the site. Similarly, while more
residential development is expected in the Neighborhood Mixed-use District, office or
commercial development could be located here. In addition, while more office
development is anticipated in the Office Mixed-use District, residential or commercial
development is also allowed without limitation.
The maximum allowable amount of development in the Plan Area is identified in the
Specific Plan as a two-tier program. Under the Tier 1 Development Program, as shown
in Table 3.2 of the Specific Plan, the amount of development in the Plan Area would be
a maximum of 2,034 residential units, a minimum of 600,000 square feet of
commercial/retail uses, a maximum of 750,000 square feet of office uses, a maximum of
191 additional hotel rooms,3 and a minimum of 6 acres of public (at -grade) open space.
There is no minimum square footage for civic/cultural uses.
Under the Tier 2 Development Program, a City -defined "community benefits density
bonus" is available for projects in the Plan Area, as an alternative to the state Density
Bonus law, that provides specified community benefits in addition to complying with
the standard requirements of the Specific Plan. As shown in Table 3.3 of the Specific
Plan, the amount of Tier 2 development in the Plan Area would be a maximum of 2,923
residential units, a minimum of 485,000 square feet of commercial/retail subject uses
(which includes 85,000 square feet for civic/cultural uses), a maximum of 1,500,000
square feet of office uses, a maximum of 250,000 square feet of office amenity space, a
maximum of 191 additional hotel rooms,4 and a minimum of 6 acres of public (at -grade)
open space.
Consistent with the adopted General Plan, and as described in Section 2.1 of the Final
EIR, the proposed Specific Plan would facilitate a total maximum development capacity
of 460,000 square feet of commercial uses (including a 60,000 square foot performing
arts theater), 1,750,000 square feet of office uses and office amenity space, 339 hotel
rooms, 2,923 residential units, and 35,000 square feet of civic space (including 10,000
square feet of governmental use and 25,000 square feet of education space). The
proposed Specific Plan development reflects the buildout assumptions (including the
adopted residential allocation available) for the site in the City's adopted General Plan.
Centrally located open space, in a Town Square format, would be provided on the site.
The balance of the commercial uses would consist of commercial uses, which include,
among other uses, retail stores and restaurants. The residential component of the project
would be multi -family attached units. It is possible that on-site commercial and
residential amenities could include pools. The office development could be occupied by
one large tenant or multiple smaller tenants.
In addition, the project includes up to 25,000 square feet of civic spaces in the form of an
adult education center and a Science Technology Engineering and Mathematics (STEM)
lab, as well as roof gardens or green roofs. The roof could include outdoor use areas

such as outdoor dining, playgrounds, walking paths, and picnic areas. It is assumed
that the green roof would not include active play fields or courts.
The development would also include residential amenities such as club houses,
gymnasiums, private open space and pools, while any office development would
include amenities such as high volume entry areas, fitness areas, anechoic chamber
areas, unoccupied lab areas, server areas, or cafes. Amenities, such as cafes or
gymnasiums, may be located on the rooftop and could add up to 20 feet to the height of
the buildings so long as they are centrally located on the building.
The maximum building height would be between 45 feet and 160 feet, with the
maximum building heights on the west side of North Wolfe Road between 60 feet and
120 feet, and the maximum building heights on the east side of North Wolfe Road
between 60 and 160 feet. The taller buildings would be located away from North Wolfe
Road and Vallco Parkway. Development would be set back a minimum of 35 feet from
face of the curb along Stevens Creek Boulevard. Under the Specific Plan, Perimeter
Road and the existing sound wall along the western site boundary would remain.
In addition, the revised project includes construction or funding for the construction of
a new City Hall at the Cupertino Civic Center as described in the City's Civic Center
Master Plan. The environmental impacts of replacing the existing City Hall building
with a new 40,000 square foot City Hall building (as well as expanding the existing
library to include a new Program Room) were evaluated in the May 2015 Cupertino Civic
Center Master Plan Initial Study, incorporated herein by reference. The City adopted a
Mitigated Negative Declaration for the Cupertino Civic Center Master Plan project and
approved the project in July 2015.5
5 Mitigated Negative Declaration (July 7, 2015) and City Council Resolution No. 15-060 (July 7,
2015).
The project would require General Plan amendments at the time of adoption of the
Specific Plan so that both documents are consistent as of the date of adoption. The
amendments would be as follows:
• The footnote to General Plan Table LU -1 would be removed, once the Specific
Plan is adopted, because it will be obsolete, and replaced with a footnote
applicable to the Specific Plan.6
• The Specific Plan would allow for an average residential density of greater than
35 units per acre plus any allowed state density bonus; therefore, the residential
density for the Plan Area in the Land Use Element (Table LU -1 and Figure LU -2)
and in the Housing Element would be amended to reflect the maximum
residential density allowed on the site.
• The General Plan would be amended to ensure that there are no inconsistencies
between the General Plan and the development standards in the Specific Plan
such as allowed land uses (e.g., civic uses), density and building height, as well
as conforming changes to the title of the Specific Plan as referenced throughout
the EIR, including amendments to Strategy LU -13.1, Goal LU -19, Policies LU -19.1
through LU 19.1.7 and Figure PA -1.
• The General Plan would be amended to remove the requirement that 30% of the
commercial space be entertainment uses.
• The General Plan would be amended to remove the requirement that buildings
must meet the 1:1 building slope line along North Wolfe Road.
In addition to General Plan amendments and adoption of a Specific Plan, the revised
project would also involve the following discretionary approvals by the City to
implement the Specific Plan, including but not limited to:
• Rezoning
• Tentative Map
• Development Permits
• Architectural and Site Approvals
6 The footnote in General Plan Table LU -1 states: "Buildout totals for Office and Residential
allocation within the Vallco Shopping District are contingent upon a Specific Plan being adopted
for this area by May 31, 2018. If a Specific Plan is not adopted by that date, City will consider
the removal of the Office and Residential Allocations for Vallco Shopping District." Source:

• Tree Removal Permits
• Encroachment Permits
• Development Agreement with Vallco Property Owner LLC (DA -2015-02, which
was applied for in 2015 and the application was reactivated in 2017 by Sand Hill
Property Company)
As set forth in Section 2.5 of the Draft EIR and Section 2.2 of the Final EIR, the City's
objectives for the project are as follows:
1. Create a distinct and memorable mixed use Town Center that is a regional
destination and is a focal point for the community involving substantial
redevelopment of the Vallco Special Area;
2. Provide adequate development capacity on the project site to help achieve the
City's Regional Housing Needs Allocation consistent with the Housing Element;
3. Provide adequate development capacity for a mix of uses that will allow for the
development of an economically feasible project;
4. Provide the City with an avenue for generating additional sales tax revenue;
5. Create a pedestrian, bike and transit -friendly environment that enhances
mobility and connectivity; and
6. Create a high-quality sustainable development with respect to energy, resources
and ecosystems that meets the City's environmental goals and the City's Climate
Action Plan.
The EIR identifies standard permit conditions and conditions of approval, which are
part of the project description, in addition to identifying mitigation measures to be
adopted. Standard permit conditions are measures required by laws and regulations
(primarily, the Cupertino Municipal Code) or are required to comply with laws and
regulations. While standard permit conditions are not mitigation measures, they may
assist in reducing environmental impacts.' Conditions of approval also are not
mitigation measures. They are required of the project by the City, but do not
necessarily reduce an environmental impact.'

III. ENVIRONMENTAL REVIEW PROCESS
In accordance with Section 15082 of the CEQA Guidelines, the City of Cupertino
prepared a Notice of Preparation ("NOP") of an EIR for the Vallco Special Area Specific
Plan project. The NOP was sent to state and local responsible and trustee agencies and
federal agencies on February 9, 2018. The 31 -day comment period concluded on March
12, 2018. The NOP provided a description of the project and identified probable
environmental effects that could result from implementation of the project. The City
also held a public scoping meeting during the comment period on February 22, 2018 to
discuss the project and solicit public input as to the scope and content of the EIR. The
meeting was held at Cupertino Community Hall located at 10350 Torre Avenue.
The City prepared the Draft EIR for the Vallco Special Area Specific Plan project in
compliance with the CEQA and the CEQA Guidelines. The Draft EIR was circulated for
public review and comment for 45 days from May 24, 2018 through July 9, 2018. During
this period, the Draft EIR was be available to the public and local, state, and federal
agencies for review and comment. Notice of the availability and completion of the Draft
EIR was sent directly to every agency, person, and organization that commented on the
NOP, as well as to the Office of Planning and Research. Written comments from public
agencies, organizations and individuals concerning the environmental review contained
in the Draft EIR were sent to the Community Development Department of the City of
Cupertino during and after the 45 -day public review period on the Draft EIR. The City
also held a public meeting to take written and oral comments on the Draft EIR on June
19, 2018.
In response to community and City interest in having a greater number of housing units
with a greater than 15 percent below -market -rate housing component and the inclusion
of substantial community amenities, the City identified a fifth alternative, the Housing
Rich Alternative, to be evaluated in a recirculated EIR Amendment. The EIR
Amendment also included clarification regarding necessary General Plan amendments;
refinements to the proposed Transportation Demand Management (TDM) Program;
addition of state density bonus law and City -defined "community benefits density
bonus" program to analysis of project and project alternatives; refinements to the
discussion of select mitigation measures and a condition of approval; and updated
numbers for existing General Plan land use allocations available citywide. These
refinements did not substantially change the analysis in the Draft EIR.
The EIR Amendment was circulated for public review and comment for 45 days from
July 6, 2018 through August 20, 2018. During this period, the EIR Amendment was
available to the public and local, state, and federal agencies for review and comment.
Notice of the availability and completion of the EIR Amendment was sent directly to
every agency, person, and organization that commented on the (NOP for the Draft EIR,
as well as to the Office of Planning and Research. Written comments from public
agencies, organizations, and individuals concerning the environmental review
contained in the EIR Amendment were sent to the Community Development
Department of the City during and after the 45 -day comment period on the EIR
Amendment. The City also held a public meeting to take written and oral comments on
the EIR Amendment on August 7, 2018.
Following the conclusion of the 45 -day public review period on the EIR Amendment,
the City prepared a Final EIR in conformance with CEQA Guidelines Section 15132. The
Final EIR includes a description of the revised project, which consists of revisions to the
previous project analyzed in the Draft EIR to address the City Council's direction to
include additional housing (including additional affordable housing) in the project in
conjunction with the desire for community benefits including a performing arts center,
a new City Hall, and transportation benefits aimed at reducing vehicle miles traveled,
as well as text revisions to the Draft EIR and EIR Amendment and responses to
comments received by the City of Cupertino on the Draft EIR and EIR Amendment.
These revisions do not require recirculation of the EIR because none of the revisions
constitute "significant new information" pursuant to CEQA Guidelines Section 15088.5
inasmuch as these changes would not result in a new environmental impact, and would
not cause a substantial increase in the severity of an environmental impact; the project
sponsor would adopt the revised mitigation measures, if the revised mitigation
measures are selected by the City Council; and the revised project and other text
revisions are substantially similar to the previously analyzed project alternatives and
the mitigation measures identified in the Draft EIR and EIR Amendment. Responses to
public agency comments on the EIR were sent to the commenting agencies on August
27, 2018.
On August 31, 2018, the Final EIR was presented to the Environmental Review
Committee ("ERC") for review and recommendation on August 31, 2018 and, after
considering the Final EIR and Staff's presentation, the ERC recommended that the City
Council certify the Final EIR. On September 4, 2018, at a duly noticed public hearing,
the Planning Commission recommended that the City Council certify the Final EIR.
IV. FINDINGS
These findings summarize the environmental determinations of the EIR about Project
impacts before and after mitigation, and do not attempt to repeat the full analysis of
each environmental impact contained in the EIR. Instead, these findings provide a
summary description of and basis for each impact in the EIR, describe the applicable
mitigation measures identified in the EIR, and state the City's findings and rationale
therefor on the significance of each impact with the adopted mitigation measures. A full
explanation of these environmental findings and conclusions can be found in the EIR,
and these findings hereby incorporate by reference the discussion and analysis in the
EIR supporting the EIR's determinations regarding mitigation measures and the
Project's impacts.
In adopting mitigation measures below, the City intends to adopt each of the mitigation
measures identified in the Final EIR. Accordingly, in the event a mitigation measure
identified in the Final EIR has been inadvertently omitted from these findings, such
mitigation measure is hereby referred to, adopted, and incorporated in the findings
below by reference. In addition, in the event the language of a mitigation measure set
forth below fails to accurately reflect the mitigation measure in the Final EIR due to a
clerical error, the language of the mitigation measure as set forth in the Final EIR shall
control unless the language of the mitigation measure has been specifically and
expressly modified by these findings.
Sections V through IX, below, provide brief descriptions of the impacts the Final EIR
identifies as either significant and unavoidable or less than significant with adopted
mitigation. These descriptions also reproduce the full text of the mitigation measures
identified in the Final EIR for each significant impact.
V. SIGNIFICANT AND UNAVOIDABLE IMPACTS WITH MITIGATION
INCORPORATED
The Final EIR identifies the following significant and unavoidable adverse impacts
associated with the approval of the Vallco Special Area Specific Plan Project, some of
which can be reduced, although not to a less -than -significant level, through
implementation of mitigation measures identified in the EIR. Pub. Resources Code §
21081(a)(1). In addition, the City cannot require adoption or implementation for
mitigation measures for some impacts, because they are within the responsibility and
jurisdiction of other public agencies. Pub. Resources Code § 21081(a)(2). Therefore, as
explained below, some impacts will remain significant and unavoidable
notwithstanding the adoption of feasible mitigation measures. To the extent that these
mitigation measures will not mitigate or avoid all significant effects on the
environment, and because the City cannot require mitigation measures that are within
the responsibility and jurisdiction of other public agencies to be adopted or
implemented by those other agencies, it is hereby determined that these significant and
unavoidable adverse impacts are acceptable for the reasons specified in Section XI,
below. Pub. Resources Code § 21081(a)(3). As explained in Section XII, below, the
findings in this Section are based on the Draft EIR, the EIR Amendment, and the Final
EIR, the discussion and analysis in which is hereby incorporated in fully by this
reference.
A. Impact AQ -2. The construction of the revised project would violate an
air quality standard or contribute substantially to an existing or
projected air quality violation.
The EIR finds that the revised project would result in significant air quality impacts
related to construction period dust and exhaust emissions. Implementation of the
project would result in short-term emissions from construction activities with
development, including site grading, asphalt paving, building construction, and
architectural coating. Emissions commonly associated with construction activities
include fugitive dust from soil disturbance, fuel combustion from mobile heavy-duty
diesel- and gasoline -powered equipment, portable auxiliary equipment, and worker
commute trips. During construction, fugitive dust, the dominant source of respirable
particulate matter (PMio) and fine particulate matter (PM2.5) emissions, is generated
when wheels or blades disturb surface materials. Uncontrolled dust from construction
can become a nuisance and potential health hazard to those living and working nearby.
Demolition and construction of buildings can also generate PM10 and PNIz.s emissions.
Off-road construction equipment is often diesel -powered and can be a substantial
source of nitrogen oxide (NO.) emissions, in addition to PM10 and PM 5 emissions. The
combination of temporary dust from activities and diesel exhaust from construction
equipment poses both a health and nuisance impact to nearby receptors.
Estimated construction emissions for the project would exceed the BAAQMD
significance threshold for NO. emissions during construction. Emissions of ROG, PMio
exhaust, and PMz.s exhaust during construction would be below BAAQMD significance
thresholds.
Implementation of MM AQ -2.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce construction -related emissions from the
project, but not to a less than significant level. Therefore, this impact is considered
significant and unavoidable.
MM AQ -2.1: Future development under the revised project shall implement the following
BAAQMD-recommended measures to control dust, particulate matter, and diesel exhaust
emissions during construction:
Basic Measures
1. All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved
access roads) shall be watered two times per day.
2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
3. All visible mud or dirt track -out onto adjacent public roads shall be removed using wet
power vacuum street sweepers at least once per day. The use of dry power sweeping is
prohibited.
4. All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph).
5. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.
Building pads shall be laid as soon as possible after grading unless seeding or soil binders
are used.
6. Idling times shall be minimized either by shutting equipment off when not in use or
reducing the maximum idling time to two minutes unless subject to state law exemptions
(e.g., safety issues). Clear signage shall be provided for construction workers at all access
points.
7. All construction equipment shall be maintained and properly tuned in accordance with
manufacturer's specifications. All equipment shall be checked by a certified mechanic and
determined to be running in proper condition prior to operation.
8. Post a publicly visible sign with the telephone number and person to contact at the Lead
Agency regarding dust complaints. This person shall respond and take corrective action
within 48 hours. The Air District's phone number shall also be visible to ensure compliance
with applicable regulations.
Applicable Enhanced Control Measures
9. All exposed surfaces shall be watered at a frequency adequate to maintain minimum soil
moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe.
10. All excavation, grading, and/or demolition activities shall be suspended when average wind
speeds exceed 20 mph and visible dust extends beyond site boundaries.
11. Windbreaks (e.g., trees, fences) shall be installed on the windward side(s) of actively
disturbed areas of construction adjacent to sensitive receptors. Wind breaks should have at
maximum 50 percent air porosity.
12. Vegetative ground cover (e.g., fast -germinating native grass seed) shall be planted in
disturbed areas as soon as possible and watered appropriately until vegetation is established.
13. The simultaneous occurrence of excavation, grading, and ground -disturbing construction
activities on the same area at any one time shall be limited. Activities shall be phased to
reduce the amount of disturbed surfaces at any one time.
14. Avoid tracking of visible soil material on to public roadways by employing the following
measures if necessary: (1) Site accesses to a distance of 100 feet from public paved roads
shall be treated with a 6 to 12 inch compacted layer of wood chips, mulch, or gravel and (2)
washing truck tires and construction equipment of prior to leaving the site.
15. Sandbags or other erosion control measures shall be installed to prevent silt runoff to public
roadways from sites with a slope greater than one percent.
16. Minimizing the idling time of diesel powered construction equipment to two minutes unless
subject to state law exemptions (e.g., safety issues).
Exhaust Control Measures
17. The project shall develop a plan demonstrating that the off-road equipment (more than 25
horsepower) to be used in the construction project (i.e., owned, leased, and subcontractor
vehicles) would achieve a minimum project wide fleet -average 25 percent NOx reduction and
65 percent PM (particulate matter) exhaust reduction compared to the CalEEMod modeled
average used in this report. Acceptable options for reducing emissions include the use of
late model engines, low -emission diesel products, alternative fuels, engine retrofit
technology, after -treatment products, add-on devices such as particulate filters, and/or other
options as such become available. The following are feasible methods:
• All construction equipment larger than 25 horsepower used at the site for more than two
continuous days or 20 hours total shall meet EPA Tier 4 emission standards for NOx and
PM, where feasible.
• If Tier 4 equipment is not feasible, all construction equipment larger than 25 horsepower
used at the site for more than two continuous days or 20 hours total shall meet EPA
emission standards for Tier 3 engines and include particulate matter emissions control
equivalent to CARB Level 3 verifiable diesel emission control devices that altogether
achieve an 85 percent reduction in particulate matter exhaust.
• Use of alternatively fueled equipment with lower NO,: emissions that meet the NOx and
PM reduction requirements above.
• Diesel engines, whether for off-road equipment or on -road vehicles, shall not be left idling
for more than two minutes, except as provided in exceptions to the applicable state
regulations (e.g., traffic conditions, safe operating conditions). The construction sites
shall have posted legible and visible signs in designated queuing areas and at the
construction site to clearly notify operators of idling limit.
• All on -road heavy-duty diesel trucks with a gross vehicle weight rating of 33,000 pounds
or greater (EMFAC Category HDDT) used at the project site (such as haul trucks, water
trucks, dump trucks, and concrete trucks) shall be model year 2010 or newer.
• Develop a Transportation Demand Management program for construction worker travel
that includes transit and carpool subsides in order to reduce worker trips.
• Provide line power to the site during the early phases of construction to minimize the use
of diesel powered stationary equipment, such as generators.
18. A project -specific construction management plan describing the measures to minimize
construction emissions shall be required of future development. As part of the construction
management plan, the on-site Construction Manager shall ensure and regularly document that
equipment, trucks, and architectural coatings meet the above mitigation requirements. The
documentation shall be submitted regularly to the City for review and compliance.
B. Impact AQ -3. The operation of the revised project would violate an air
quality standard or contribute substantially to an existing or projected
air quality violation.
The EIR finds that the revised project would exceed the significance thresholds for all
criteria air pollutant emissions (ROG, NOx, PMio, and PMz.$) on an annual and daily
basis, primarily due to the amount of development proposed and the substantial
amount of vehicle trips generated by the proposed uses. Accordingly, operational
emissions typically represent the majority of a project's air quality impacts. After a
project is built, operational emissions, including mobile and area sources (including tire
wear and brake wear), are anticipated to occur continuously throughout the project's
lifetime.
Implementation of the proposed TDM program and MM AQ -3.1, set forth below, which
is hereby adopted and incorporated into the project, would reduce the impact but not to
a less than significant level. Therefore, this impact is considered significant and
unavoidable.
MM AQ -3.1: Future development under the revised project shall use low-VOC paint (i.e., 50
g/L or less) on operational architectural coatings and no hearths or fireplaces (including natural
gas -powered) shall be installed in the residential units.
C. Impact AQ -4. The revised project would result in a cumulatively
considerable net increase in criteria pollutants (ROG, NO., PM1o, and/or
PM2.$) for which the project region is non -attainment under an
applicable federal or state ambient air quality standard.
The discussion under Impact AQ -3 addresses cumulatively considerable net increases
of criteria pollutants or precursors. The project would have a cumulatively considerable
net increase in criteria air pollutants (ROG, NOx, PMio, and PM2.5) and those emissions
are considered significant and unavoidable.
Implementation of MM AQ -4.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the impact but not to a less than significant
level. Therefore, this impact is considered significant and unavoidable.
MM AQ -4.1: Implement MM AQ -3.1.
D. Impact AQ -6. The revised project would expose sensitive receptors to
substantial construction dust and diesel exhaust emissions
concentrations.
The revised project would expose sensitive receptors to concentrations of NOx
emissions that exceed the BAAQMD's threshold during construction. The exposure of
nearby sensitive receptors to construction -related dust and diesel exhaust emissions is
discussed under Impact AQ -2, above.
Implementation of MM AQ -6, set forth below, which is hereby adopted and
incorporated into the project, would reduce the impact but not to a less than significant
level. Therefore, this impact is considered significant and unavoidable.
MM AQ -6-1: Implement MM AQ -2.1.
E. Impact NOI-1. The revised project would expose persons to or
generation of noise levels in excess of standards established in the
General Plan Municipal code, or applicable standard of other agencies.
The EIR finds that the revised project would result in construction noise that could
expose sensitive receptors to noise levels that exceed noise standards set forth in the
City's Municipal Code. Construction activities could generate considerable amounts of
noise, especially during demolition, earth -moving, and infrastructure construction
phases when heavy equipment is used. The highest maximum noise levels generated
by construction of the project would typically range from about 80 to 90 dBA Lmax at a
distance of 50 feet from the noise source. The Specific Plan includes a 56 foot "no build"
zone along the property lines of the single family residences on the west side of the
project area. The only types of construction in this zone would be streets, bike lanes,
open space and trails, This will help attenuate noise impacts from construction.
Several individual pieces of construction equipment would potentially produce noise
levels that would exceed the City's 87 dBA L.. limit at 25 feet; the noisiest of which
would be impact pile driving. Impact pile driving would result in maximum noise
levels up to 105 dBA L.. at 50 feet, which would equate to 111 dBA L.. at 25 feet. This
would be a potentially significant impact. Further, it is conservatively assumed that
construction activities on the project site would exceed the 80 dBA Leq threshold at the
property lines of the nearby existing residences.
Implementation of MM NOI-1.1, MM NOI-1.2, MM NOI-1.3, MM NOI-1.4, MM NOI-
1.5, set forth below, which are hereby adopted and incorporated into the project, may
not mitigate construction noise of individual projects to a less than significant level.
Therefore, impacts from construction noise would be significant and unavoidable.
MM NOI-1.1: Construction activities under the revised project shall be conducted in
accordance with provisions of the City's Municipal Code which limit temporary construction
work to daytime hours,9 Monday through Friday. Certain types of construction are prohibited
on weekends and all holidays pursuant to Municipal Code Sections 10.48.053(B), (C) and (D).lo
Further, the Cihj requires that all equipment have high-qualihj noise mufflers and abatement
devices installed and are in good condition. Additionally, the construction crew shall adhere to
the following construction best management practices listed in MM NOI-1.2 below to reduce
construction noise levels emanating from the site and minimize disruption and annoyance at
existing noise -sensitive receptors in the project vicinity.
9 Pursuant to Municipal Code Section 10.48.010, "daytime" is defined as the period from 7:00
AM to 8:00 PM weekdays.
io Municipal Code Section 10.48.053(B): Notwithstanding Section 10.48.053A, it is a violation
of this chapter to engage in any grading, street construction, demolition or underground utility
work within seven hundred fifty feet of a residential area on Saturdays, Sundays and holidays,
and during the nighttime period, except as provided in Section 10.48.030. Municipal Code
Section 10.48.053(C): Construction, other than street construction, is prohibited on holidays,
except as provided in Sections 10.48.029 and 10.48.030. Municipal Code Section 10.48.053(D):
Construction, other than street construction, is prohibited during nighttime periods unless it
meets the nighttime standards of Section 10.48.040.
MM NOI-1.2: Future development shall prepare and submit a construction noise control plan
to the City's Building Department and Code Enforcement for review and approval. The on-site
Construction Manager shall implement the construction noise control plan, which would
include, but is not limited to, the following available controls:
• Construct temporary noise barriers, where feasible, to screen stationary noise -generating
equipment. Temporary noise barrier fences would provide a five dBA noise reduction if the
noise barrier interrupts the line -of -sight between the noise source and receptor and if the
barrier is constructed in a manner that eliminates any cracks or gaps.
• Equip all internal combustion engine -driven equipment with intake and exhaust mufflers
that are in good condition and appropriate for the equipment.
• Enforce idling limit of two minutes for internal combustion engines unless subject to state
law exemptions (e.g., safety issues).
• Locate stationary noise -generating equipment, such as air compressors or portable power
generators, as far as possible from sensitive receptors as feasible. If they must be located
near receptors, adequate muffling (with enclosures where feasible and appropriate) shall be
used to reduce noise levels at the adjacent sensitive receptors. Any enclosure openings or
venting shall face away from sensitive receptors.
• Utilize "quiet" air compressors and other stationary noise sources where technology exists.
• Construction staging areas shall be established at locations that would create the greatest
distance between the construction -related noise sources and noise -sensitive receptors nearest
the project site during all project construction.
• Locate material stockpiles, as well as main tenancelequ ipmen t staging and parking areas, as
far as feasible from residential receptors.
• Control noise from construction workers' radios to a point where they are not audible at
existing residences bordering the project site.
• If impact pile driving is proposed, temporary noise control blanket barriers shall shroud pile
drivers or be erected in a manner to shield the adjacent land uses.
• If impact pile driving is proposed, foundation pile holes shall be pre -drilled to minimize the
number of impacts required to seat the pile. Pre -drilling foundation pile holes is a standard
construction noise control technique. Pre -drilling reduces the number of blows required to
seat the pile. Notify all adjacent land uses of the construction schedule in writing.
• The contractor shall prepare a detailed construction schedule for major noise -generating
construction activities and provide it to adjacent land uses. The construction plan shall
identifij a procedure for coordination with adjacent residential land uses so that construction
activities can be scheduled to minimize noise disturbance.
Designate a "disturbance coordinator" who would be responsible for responding to any
complaints about construction noise. The disturbance coordinator would determine the
cause of the noise complaint (e.g., bad muffler, etc.) and would require that reasonable
measures be implemented to correct the problem. The telephone number for the disturbance
coordinator shall be conspicuously posted at the construction site and included in the notice
sent to neighbors regarding the construction schedule.
MM N0I-1.3: A qualified acoustical consultant shall be retained for development under the
revised project to review mechanical noise, as these systems are selected, to determine specific
noise reduction measures necessary to ensure noise complies with the City's noise level
requirements. Mechanical equipment shall be selected and designed to reduce impacts on
surrounding uses to meet the City's noise level requirements. Noise reduction measures could
include, but are not limited to:
Selection of equipment that emits low noise levels;
Installation of noise dampening techniques, such as enclosures and parapet walls, to block
the line -of -sight between the noise source and the nearest receptors;
Locating equipment in less noise -sensitive areas, where feasible.
MM N0I-1.4: Section 10.48.062 prohibits deliveries between 8:00 PM and 8:00 AM on
weekdays and between 6:00 PM and 9:00 AM on weekends and holidays, which shall be enforced
as part of the revised project. Additionally, the effect of loading zone activities would be
evaluated for noise impacts and help determine design decisions once project -specific information
for the revised project, such as type and size of the commercial uses, hours of operation,
frequency of deliveries, and location of loading zones, is available. Noise reduction measures
could include, but are not limited to, the following:
• Move loading zones inside (e.g., within parking structures), where possible, and as far from
adjacent residential uses as possible.
• Implement a no idling policy at all locations that requires engines to be turned off after two
minutes.
• Recess truck docks into the ground or locate them within parking structures.
• Equip loading bay doors with rubberized gasket type seals to allow little loading noise to
escape.
MM N0I-1.5: Prior to issuance of building permits, a noise study shall be completed to
determine noise levels due to truck deliveries at the proposed buildings, and the specific noise
control that shall be implemented to reduce noise levels below the City's thresholds at adjacent
residential property lines shall be identified.
F. Impact N0I-3. The revised project would result in substantial
permanent increase in ambient noise levels in the project vicinity above
levels existing without the project.
The EIR finds that the revised project would generate approximately 39,063 average
daily trips and would result in permanent ambient noise increase due to project -
generated traffic.
Implementation of MM N0I-3.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the impact but not to a less than significant
level because vehicle speed is already limited. Therefore, impacts would be significant
and unavoidable.
MM N0I-3.1: Future development under the revised project shall implement available
measures to reduce project -generated noise level increases from project traffic on Perimeter Road.
The noise attenuation measures shall be studied on a case-by-case basis at receptors that would
be significantly impacted. Noise reduction methods could include the following:
• Alternative noise reduction techniques, such as re -paving Perimeter Road with "quieter"
pavement types including Open -Grade Rubberized Asphaltic Concrete. The use of "quiet"
pavement can reduce noise levels by two to five dBA, depending on the existing pavement
type, traffic speed, traffic volumes, and other factors.
• Traffic calming measures to slow traffic, such as speed bumps.
• Building sound insulation for affected residences, such as sound -rated windows and doors,
on a case-by-case basis as a method of reducing noise levels in interior spaces.
G. Impact N0I4. The revised project would result in a substantial
temporary or periodic increase in ambient noise levels in the project
vicinity above levels existing without the project.
The EIR finds that the revised project would result in significant temporary increase in
ambient noise levels due to construction activities. Pile driving activities are expected to
exceed maximum noise thresholds established in the City's Municipal Code for
individual pieces of equipment, even with the implementation of the Construction Best
Management Practices. Further, the temporary construction noise impact would be
considered significant, if project construction activities exceeded 60 dBA Leq at nearby
residences or exceeded 70 dBA Ley at nearby commercial land uses and exceeded the
ambient noise environment by five dBA Leq or more for a period longer than one year.
Based on the hourly average noise levels, construction activities within 50 feet of the
property lines of the nearby residential and commercial land uses would exceed 60 and
70 dBA L,,, respectively, and exceed ambient noise levels by more than five dBA
throughout construction. This would result in indoor speech interference and
disruption for a period of up to 10 years. Thus, construction noise associated with the
project could expose nearby sensitive receptors to elevated noise levels over a period of
up to 10 years.
Implementation of MM NOI-4.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce construction noise levels emanating from
the site and minimize disruption and annoyance to the extent feasible but not to a less
than significant level because of the extended period anticipated for the project
construction. Therefore, the impact would remain significant and unavoidable.
MM NOI-4.1: Implement MM N0I-1.1 and -1.2.
H. Impact TRN-1. Under existing project conditions, the revised project
would conflict with an applicable plan, ordinance, or policy
establishing measures of effectiveness for the performance of the
circulation system; and conflict with an applicable congestion
management program, including standards established for designated
roads or highways.
The EIR finds that the revised project would result in a significant intersection level of
service impacts under existing with project conditions, defined as existing conditions
plus traffic generated by buildout of the project, as the following intersections:
12. De Anza Boulevard/McClellan Road (City of Cupertino) — PM peak hour; and
43. Stevens Creek Boulevard/Stern Avenue (City of Santa Clara) — PM peak hour.
The revised project would also significantly impact 14 mixed -flow segments in the AM
peak hour, 18 mixed -flow segments in the PM peak hour, five HOV segments in the AM
peak hour, and five HOV segments in the PM peak hour.
Implementation of MM TRN-1.1, MM TRN-1.2, and MM TRN-1.3, set forth below, are
hereby adopted and incorporated into the project, would reduce the impacts but not to
a less than significant level. Therefore, the impacts would remain significant and
unavoidable.
MM TRN-1.1: Develop and implement a TDM Program which includes a trip cap that is based
on a 34 percent non -SOV rate for the office uses. The TDM program includes the creation of a
Transportation Management Association that would:
• Provide concierge services to residents and retail owners (for their employees);
• Coordinate with the office component; and
• Oversee the overall TDM program among property owners and tenants to achieve the
office trip caps
As part of the TDM Program, the City shall require future development to implement the
Specific Plan's TDM Monitoring Program to ensure that the TDM reduction goals are achieved.
The TDM Monitoring Program shall require a robust Monitoring Program to ensure that this
TDM program mitigation measure is implemented and that the required trip caps are achieved.
The Monitoring Program shall be subject to review and approval by the City of Cupertino and
would include driveway monitoring for all office uses during the AM and PM peak hours. The
TDM Monitoring Program would occur in the fall (mid-September through mid-November)
after six months occupancy of 50 percent of the total approved buildout. The TDM Monitoring
Program shall be conducted annually for the first 10 years. If the monitoring reveals that the
peak trip counts have not been exceeded in the last three years of the first 10 years of annual
monitoring, the TDM monitoring shall be reduced to once every two years (i.e.. year 10, 12, 14,
etc.). However, if any biennial report reveals that the peak trip counts have been exceeded, the
monitoring shall revert to annual monitoring until such time that the peak trip counts have not
been exceeded for three consecutive annual reports. If future development is not able to meet the
identified TDM goal, then the City would collect penalties (assigned proportionately between the
uses that do not meet the trip cap), as specified in the Specific Plan's TDM Monitoring Program.
Penalties collected from the TDM Monitoring Program will be used to improve multimodal
access around the site and throughout the City of Cupertino.
MM TRN-1.2: Intersection 12, De Anza Boulevard/McClellan Road: convert the shared left-
turn/through lane on the eastbound approach of McClellan Road to a dedicated through lane (for
a total of one left -turn lane, one through lane, and one right -turn lane). This would allow
converting the phasing on the east -west approaches from split phasing to protected left -turn
phasing. This improvement is included in the City's TIF Program and would improve
intersection operations to an acceptable LOS D. Future development under the revised project
shall pay transportation mitigation fees as calculated pursuant to the TIF program to mitigate
this impact.
Because the TIF improvements are not fully funding and the timing of implementation
is not known at this time, however, the impact to Intersection 12 is considered
significant and unavoidable.
MM TRN-1.3: A fair -share payment contribution of $3,865,182.00 to improvements identified
in VTA's VTP 2040 for freeway segments on SR 85,1-280, and I-880 that the project (or project
alternative) significantly impacts shall be paid by future development associated with the revised
project.
The VTA's VTP 2040 identifies several freeway projects that are relevant to the identified
freeway segment impacts, including:
• VTP ID H1: SR 85 Express Lanes: US 101 (South San Jose to Mountain View). This project
would convert 24 miles of existing HOV lanes to express lanes, and allow single -occupancy
vehicles access to the express lanes by paying a toll. An additional express lane will be added
to create a two-lane express lane along a portion of the corridor. On November 13, 2017, the
cities of Cupertino and Saratoga and the Town of Los Gatos entered into a settlement
agreement" with VTA and Caltrans that requires VTA to implement the 2016 Measure B
State Route 85 Corridor Program Guidelines which include preparing a Transit Guideway
Study for this corridor to identifi, j the most effective transit and congestion relief projects on
SR 85 that will be candidates for funding. Upon completion of the study, and
implementation plan for these projects will be developed.
• VTP ID H11: I-280 Express Lanes: Leland Avenue to Magdalena Avenue. This project
converts existing HOV lanes to express lanes.
• VTP ID H13: I-280 Express Lanes: Southbound El Monte Avenue to Magdalena Avenue.
This project builds new express lanes.
• VTP ID H15: I-880 Express Lanes: US 101 to I-280. This project would build new express
lanes on I-880.
• VTP ID H35: I-280 Northbound: Second Exit Lane to Foothill Expressway. This project
constructs a second exit lane from northbound I-280 to Foothill Expressway.
• VTP ID H45: I-280 Northbound Braided Ramps between Foothill Expressway and SR 85:
This project would conduct preliminary engineering, environmental studies, and design to
widen the existing off -ramp to Foothill Expressway from Northbound I-280 from a single -
lane exit to a two-lane exit opening at I-280.
As part of the Settlement Agreement, City of Saratoga, et al. v. California Department of
Transportation, et al. (Santa Clara County Superior Court Case No. 115CV281214), which was
a suit by the three cities challenging Caltrans's approval of the State Route 85 Express Lanes
Project, was dismissed on November 17, 2017.
I. Impact TRN-2. Under background with project conditions, the revised
project would conflict with an applicable plan, ordinance, or policy
establishing measures of effectiveness for the performance of the
circulation system; and conflict with an applicable congestion
management program, including standards established for designated
roads or highways.
The EIR finds that the revised project would result in a significant intersection level of
service impact under background with project conditions, defined as background
conditions plus traffic generated by buildout of the project, at the following 11
intersections:
11. De Anza Boulevard/Stevens Creek Boulevard (City of Cupertino) - PM peak
hour;
12. De Anza Boulevard/McClellan Road (City of Cupertino) - PM peak hour;
31. Wolfe Road and Vallco Parkway (City of Cupertino) - PM peak hour;
32. Wolfe Road -Miller Avenue/Stevens Creek Boulevard (City of Cupertino)* - AM
and PM peak hours;
42. Stevens Creek Boulevard/Tantau Avenue (City of Cupertino) - AM peak hour;
43. Stevens Creek Boulevard/Stern Avenue (City of Santa Clara) - AM and PM peak
hours;
44. Stevens Creek Boulevard/Calvert Drive/I-280 Ramps (west) (City of Santa Clara)*
- AM and PM peak hours;
45. Stevens Creek Boulevard/Agilent Driveway (City of Santa Clara) - AM peak
hour;
48. Lawrence Expressway/Homestead Road (Santa Clara County)* - PM peak hour;
51. Lawrence Expressway/Calvert Drive -I-280 Southbound Ramp (City of San Jose)*
- AM peak hour; and
53. Lawrence Expressway/Bollinger Road (Santa Clara County)* - AM and PM peak
hours.
* denotes CMP intersection
The revised project would also result in a significant freeway level of service impacts
under background with project conditions at 15 mixed flow lanes in the AM peak hour,
20 mixed flow lanes in the PM peak hour, four HOV lanes in the AM peak hour, and
five HOV lanes in the PM peak hour.
Implementation of MM TRN-2.1, MM TRN-2.2, MM TRN-2.3, MM TRN-2.4, MM TRN-
2.4, MM TRN-2.5, MM TRN-2.6, MM TRN-2.7, MM TRN-2.8, and MM TRN-2.9, set
forth below, which are hereby adopted and incorporated into the project, would reduce
the impacts but not to a less than significant level. Therefore, the impacts would remain
significant and unavoidable.
MM TRN-2.1: Implement MM TRN-1.1.
The TDM program is expected to reduce the severity of intersection and freeway
impacts, although not necessarily to a less than significant level.
MM TRN-2.2: Intersection 12, De Anza Boulevard/McClellan Road: Implement MM TRN-
1.2. Implementation of MM TRN-1.2 would improve intersection the average intersection delay
to better than background (without project or project alternative) conditions.
Because the TIF improvements are not fully funded and the timing of implementation is
not known at this time, the impact is considered significant and unavoidable.
MM TRN-2.3: Intersection 31, Wolfe Road/Vallco Parkway: Provide an overlap phase for the
westbound right -turn movement, which would provide for a green right -turn arrow while the
southbound left -turn movement has its green phase. Southbound U-turns shall also be
prohibited. Implementation of this mitigation measure would improve intersection level of
service to an acceptable LOS D.
MM TRN-2.4: Intersection 42, Stevens Creek Boulevard/Tantau Avenue: Provide a
northbound left -turn lane (for a total of one left -turn lane and one shared through/right-turn
lane). This would allow converting the phasing on the east -west approaches from split phasing
to protected left -turn phasing. This improvement is included in the City's TIF Program and
would improve intersection operations to an acceptable LOS D. Future development under the
revised project shall pay transportation mitigation fees as calculated pursuant to the TIF
program to mitigate this impact.
Because the TIF improvements are not fully funding and the timing of implementation
is not known at this time, however, the impact is considered significant and
unavoidable.
MM TRN-2.5: Intersections 43-45: Contribute a fair -share of $96,000.00 to a traffic signal
timing study and implementation of the revised timings on Stevens Creek Boulevard at Stern
Avenue, Calvert Drive, and Agilent Driveway
The revised project impacts would likely improve with modifications to the signal
timings as traffic volumes change, but the impact is concluded to be significant and
unavoidable because the effectiveness of the improvement would be determined
through the signal timing study and because the intersection is under the jurisdiction of
another agency and the City cannot guarantee the implementation of the signal timing
study.
MM TRN-2.6: Intersection 48, Lawrence Expressway/Homestead Road: Pay a fair -share
contribution of $219,000.00 to the near-term improvement identified in the Santa Clara
County's Expressway Plan 2040 Study for this intersection. The Expressway Plan 2040 Study
identifies a near-term improvement of an additional eastbound through lane on Homestead Road.
With this improvement, intersection operations would improve, but the intersection would
continue to operate at LOS F with delays greater than under background conditions.
The ultimate improvement identified by the County's Expressway Plan 2040 is to grade -
separate the intersection. That is a long-term improvement, however, which would not
be implemented within the next 10 years. Furthermore, the improvement is under the
jurisdiction of another agency and the City cannot guarantee its implementation.
Therefore, the impact is considered significant and unavoidable.
MM TRN-2.7: Intersection 51, Lawrence Expressway/Calvert Drive -I-280 Southbound Ramp:
Improvements to mitigate the impact would include providing a fourth northbound through lane
(for a total of four through lanes and one right -turn lane). This would require four receiving
lanes north of Calvert Drive -I-280 Southbound Ramps. With this improvement, the intersection
would operate at acceptable LOS E or better. The widening of Lawrence Expressway from three
to four lanes in each direction between Moorpark Avenue to south of Calvert Drive is included
in the VTP 2040 as a constrained project (VTP 2040 Project# X10). The VTP 2040 does not
include widening of Lawrence Expressway at or north of Calvert Drive, however. The fourth
northbound through lane on Lawrence Expressway could potentially be provided with an added
receiving lane that would connect directly to the off -ramp to Lawrence Expressway (also known
as "trap" lane) just north of the I-280 overcrossing. The City shall coordinate with the County of
Santa Clara to and Caltrans to determine if a fourth through lane could be provided. Future
development tinder the proposed project shall be required to pay a fair -share contribution of
$133,380.00 if the improvement is feasible.
The impact would remain significant and unavoidable because the feasibility of the
improvement is yet to be determined, and because the intersection is within the
responsibility and jurisdiction of another agency and the City cannot guarantee the
improvement would be constructed concurrent with the proposed project.
MM TRN-2.8: Intersection 53, Lawrence Expressway/Bollinger Road: Improvements to
mitigate the revised project's impact would include providing a fourth northbound through lane
(for the PM peak hour impact) and fourth southbound through lane (for the AM peak hour
impact). The widening of Lawrence Expressway from three to four lanes in each direction
between Moorpark Avenue to south of Calvert Drive is included in the VTP 2040 as a
constrained project (VTP 2040 Project# X10). This VTA project also includes the provision of
an additional westbound through lane on Moorpark Avenue.
Assuming that both the northbound and southbound approaches would be modified to
accommodate four through lanes, the intersection would operate at or better than acceptable LOS
E under the revised project during the AM and PM peak hours. Future development under the
revised project shall be required to pay a fair -share contribution of $133,380.00 to VTP Project#
X10.
The impact would remain significant and unavoidable, however, because the
intersection is within the responsibility and jurisdiction of another agency and the City
cannot guarantee the improvement would be constructed concurrent with the proposed
project.
MM TRN-2.9: Implement A4A4 TRN-1.2.
The VTP 2040 projects will enhance vehicular travel choices for the project (and project
alternatives), and make more efficient use of the transportation roadway network, and
the SR 85 Transit Guideway Study will help improve transit options in the SR 85
corridor. These freeway operations enhancements would not improve all impacted
freeway segments to less than significant levels, however. The TDM Program proposed
under the revised project and mitigation measure MM TRN-2.1 would reduce project -
generated vehicle trips, thereby reducing the revised project impact on freeway
segments, but it is not anticipated that the freeway impacts would be reduced to a less
than significant level. For the above reasons, the revised project would remain
significant and unavoidable with the implementation of MM TRN-2.1 and -2.9.
VI. SIGNIFICANT ADVERSE IMPACTS IDENTIFIED IN THE FINAL EIR THAT
ARE REDUCED TO A LESS -THAN -SIGNIFICANT LEVEL BY MITIGATION
MEASURES ADOPTED AND INCORPORATED INTO THE PROJECT
The Final EIR identifies the following significant impacts associated with the revised
project. It is hereby determined that the impacts addressed by these mitigation
measures will be mitigated to a less than significant level or avoided by adopting and
incorporating these mitigation measures into the project. The findings in this section are
based on the Draft EIR, the EIR Amendment, and the Final EIR, the discussion and
analysis in which is hereby incorporated in full by this reference.
A. Impact AQ -7. The revised project would expose sensitive receptors to
substantial TAC pollutant concentrations.
The EIR finds that the revised project would result in construction -related health risk
exposures to sensitive receptors given the timeframe for construction and the amount of
development.
Construction equipment and associated heavy-duty truck traffic generates diesel
exhaust, which is a known Toxic Air Contaminant (TAC). The primary community risk
impact issues associated with construction emissions are cancer risk and exposure to
PM2.5 from diesel exhaust. Accordingly, the maximum excess cancer risk would be 26.7
in one million, which exceeds the BAAQMD threshold of significance of 10 in one
million. The maximum annual PM2.5 concentration, which is based on combined exhaust
and fugitive dust emission, is 0.25 micrograms per cubic meter (µg/m3) and does not
exceed the BAAQMD threshold of significance of 0.3 µg/m3. The maximum Hazard
Index (non -cancer health hazards from TAC exposure) is 0.01, which is below the
BAAQMD threshold of significance of 1.0.
Implementation of MM AQ -7.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the impact to a less than significant
cumulative health risk impact.
MM AQ -7.1: Future development under the revised project shall implement mitigation measure
MM AQ -2.1 to reduce on-site diesel exhaust emissions, which would thereby reduce the
maximum cancer risk due to construction of the project.
B. Impact CR -2. The revised project would not significantly impact
archaeological resources, human remains, or tribal cultural resources.
The EIR finds that the revised project site would have a low to moderate potential for
containing buried archaeological resources. To date, no archaeological resources have
been recorded on or adjacent to the project site.
Based on a conservative estimate of parking demand, it is anticipated that the project
would require multiple levels of below grade parking across most of the site (51 acres).
The below ground parking over 51 acres would require a maximum excavation depth
of 20 to 50 feet for the project and project alternatives. If any archaeological resource,
human remains, or tribal cultural resources be found during project excavation and
grading activities, their disturbance would be a significant impact.
Implementation of MM CR -2.1, MM CR -2.2, MM CR -2.3, and MM CR -2.4, set forth
below, which are hereby adopted and incorporated into the project, would reduce the
impact to a less than significant impact.
MM CR -2.1: A qualified archaeological monitor shall be retained by the project proponent for
future development under the revised project to inspect the ground surface at the completion of
demolition activities as they occur to search for archaeological site indicators. Site indicators
include, but are not limited to: darker than surrounding soils of a friable nature, evidence of fires
(ash, charcoal, fire affected rock or earth); concentrations of stone, bone, or shellfish; artifacts of
stone, bone, or shellfish; and burials, either human or animal.
In the event that any indicators are discovered, work shall be halted within a sensitivity zone to
be determined by the archaeologist. The archaeologist shall prepare a plan for the evaluation of
the resource to the CRHP and submit the plan to the Cupertino Planning Department for review
and approval prior to any construction related earthmoving within the identified zone of
archaeological sensitivity. The plan shall also include appropriate recommendations regarding
the significance of the find and the appropriate mitigation. The identified mitigation shall be
implemented and can take the form of limited data retrieval through hand excavation coupled
with continued archaeological monitoring inside of the archaeologically sensitive zone to ensure
that significant data and materials are recorded and/or removed for analysis. Monitoring also
serves to identify and thus limit damage to human remains and associated grave goods.
MM CR -2.2: Pursuant to Section 7050.5 of the Health and Safety Code and Section 5097.94 of
the Public Resources Code of the State of California, in the event of the discovery of human
remains during construction of the revised project, there shall be no further excavation or
disturbance of the site within a 100 foot radius of the remains or any nearby area reasonably
suspected to overlie adjacent remains. The Santa Clara County Coroner shall be notified and
shall make a determination as to whether the remains are Native American. If the Coroner
determines that the remains are not subject to his authority, he shall notify the NAHC within 24
hours. The NAHC shall attempt to identify descendants of the deceased Native American. If no
satisfactory agreement can be reached as to the disposition of the remains pursuant to this State
law, then the land owner shall re -inter the human remains and items associated with Native
American burials on the property in a location not subject to further subsurface disturbance.
MM CR -2.3: If archaeological resources are identified during construction of the revised project,
a final report summarizing the discovery of cultural materials shall be submitted to the City's
Project Planner prior to issuance of building permits. This report shall contain a description of
the mitigation program that was implemented and its results, including a description of the
monitoring and testing program, a list of the resoicrces found and conclusion, and a description
of the dispositionlcuration of the resotcrces.
MM CR -2.4: The City of Cupertino shall coordinate with the applicable Native American tribal
representatives following approval of a development on-site under the revised project to ensure
appropriate ctcltural sensitivity training is provided to all contractors prior to the start of
ground -disturbing activities.
C. Impact HAZ-1. The revised project would not create a significant hazard
to the public or the environment through routine transport, use,
disposal, or foreseeable upset of hazardous materials; or emit hazardous
emissions or hazardous materials within one-quarter mile of an existing
or proposed school.
The EIR finds that the revised project would result in a potential for on-site soil, soil
vapor, and groundwater contamination above regulatory screening levels for
residential and commercial uses due to historic and existing hazardous materials use,
generation, and storage.
Construction of the project would result in the demolition of existing structures and
excavation up to a maximum dept of 20 to 50 feet for below ground parking. Unless
properly handled and disposed of, the removal and transport of on-site hazardous
materials could present a risk to the environment (including LP Collins Elementary
School/Bright Horizons at Cupertino Pre -School, which are within 0.25 miles of the
project site to the west), construction workers, and future occupants.
The revised project does not propose any on-site use of hazardous materials other than
small quantities of herbicides and pesticides for landscaping maintenance and cleaning
and pool chemicals. The use, storage, and transportation and disposal of pool cleaning
and maintenance chemicals would be managed in accordance with federal, state, and
local laws and regulations that ensure on-site use, storage, transportation and disposal
of chemicals will result in a less than significant impact. No other routine use, storage,
transportation, or disposal of hazardous materials is anticipated as part of the project.
Implementation of MM HAZ-1.1, MM HAZ-1.2, MM HAZ-1.3, and MM HAZ-1.4, set
forth below, which are hereby adopted and incorporated into the project, would reduce
on-site hazardous materials impacts from demolition, excavation, and construction to a
less than significant level by creating and implementing an SMP and HSP to establish
practices for properly handling contaminated materials, implementing measures during
demolition activities to identify, remove, and clean up hazardous materials on-site,
properly closing groundwater monitoring wells, and obtaining site closure from
regulatory agencies. Thus, the impact would be reduced to a less than significant
impact.
MM HAZ-1.1: A Site Management Plan (SMP) and Health and Safety Plan (HSP) shall be
prepared and implemented for demolition and redevelopment activities under the revised project.
The purpose of the SMP and HSP is to establish appropriate management practices for handling
impacted soil, soil vapor, and groundwater or other materials that may potentially be
encountered during construction activities, especially in areas of former hazardous materials
storage and use, and the profiling of soil planned for off-site disposal and/or reuse on-site. The
SMP shall document former and suspect UST locations, hazardous materials transfer lines, oil -
water separators, neutralization chambers, and hydraulic lifts, etc. The SMP shall also identifij
the protocols for accepting imported fill materials, if needed. The SMP and HSP shall be
submitted to SCCDEH for approval and the approved SMP and HSP shall be submitted to the
City Building Division prior to commencement of construction (including demolition) activities.
MM HAZ-1.2: The site contains equipment and facilities associated with past activities that are
known to or may contain residual hazardous materials. The following measures shall be
implemented under the revised project during building demolition and shall be indicated on
demolition plans:
• Sears and JC Penney Automotive Centers:
— Sears: Remnant piping that appears to have formerly distributed grease, oil and
transmission fluid from storage locations to the service bays located along interior
building walls, ceilings and within the basement shall be properly removed and
disposed, and stains and residual oil shall be cleaned from the interior building
surfaces. This work shall be coordinated with the SCCFD.
— Sears: The below ground oil -water separator (connected to floor drains within the
building) and an acid neutralization chamber (connected to drains within a former
battery storage room) shall be cleaned and removed. This work shall be coordinated
with the SCCFD and SCCDEH. Soil quality below each of the structures shall be
evaluated via sampling and laboratory analyses.
— Sears: The potential presence of a waste oil UST shall be further investigation by
removing the access cover and, if uncertainty remains, the subsequent performance of
a geophysical survey. If a UST is identified, it shall be removed in coordination with
the SCCFD and SCCDEH, and underlying soil quality shall be evaluated. If no UST
is identified, soil quality at the location of the waste oil UST, as depicted on the 1969
building plan, shall be evaluated via the collection of soil samples from borings for
laboratory analyses.
— Sears and JC Penney: Each of the below -ground lift casings and any associated
hydraulic fluid piping and reservoirs from hydraulic lifts shall be removed and
properly disposed. An Environmental Professional shall be retained to observe the
removal activities and, if evidence of leakage is identified, soil sampling and
laboratory analyses shall be conducted.
— JC Penney: The project proponent shall obtain a permit from SCCDEH to properly
remove and dispose of the 750 gallon oil -water separator during redevelopment
activities. Collection and analysis of confirmation soil samples would be required
under oversight of SCCDEH.
• Existing staining and spilled oil on-site, including at the Sears Automotive Center and
Cupertino Ice Center, shall be properly cleaned. When these facilities are demolished, an
Environmental Professional shall be present to observe underlying soil for evidence of
potential impacts and, if observed, collect soil samples for laboratory analyses.
• If the lead-based paint on-site is flaking, peeling, or blistering, it shall be removed prior
to demolition. Applicable OSHA regulations shall be followed; these include
requirements for worker training and air monitoring and dust control. Any debris
containing lead shall be disposed appropriately.
• An asbestos survey shall be completed of the buildings prior to their demolition in
accordance with the National Emissions Standards for Hazardous Air Pollutants
(NESHAP) guidelines. NESHAP guidelines require the removal of potentially friable
ACMs prior to building demolition or renovation that may disturb the ACM.
• Once existing buildings and improvements are removed, soil sampling shall be
completed to evaluate if agricultural chemicals and lead are present. The agricultural
pesticide sampling shall focus on former orchard and row crop areas, as well as in the
vicinity of outbuilding (barns and sheds) that were formerly located on the southeast
portion of the site. Testing for lead contamination shall be completed at the former
structure locations. The sampling, which shall follow commonly accepted
environmental protocols, shall be performed prior to soil excavation activities in order to
appropriately profile the soil for off -haul to a disposal facility. The analytical data shall
be compared to either residential screening levels and/or the specific acceptance criteria
of the accepting facility. If this soil is planned to be reused on-site, it shall be compared
to residential screening levels and/or natural background levels of metals.
MM HAZ-1.3: Prior to issuance of demolition and/or grading permits, groundwater
monitoring zvells shall be properly destroyed in accordance with the SCVWD Ordinance 90-1.
MM HAZ-1.4: As part of the facility closure process for occupants that use and/or store
hazardous materials, the SCCFD and SCCDEH typically require that a closure plan be
submitted by the occupant that describes required closure activities, such as removal of
remaining hazardous materials, cleaning of hazardous material handling equipment,
decontamination of building surfaces, and waste disposal practices, among others. Facility
closures shall be coordinated with the Fire Department and SCCDEH to ensure that required
closure activities are completed prior to issuance of demolition and/or grading permits.
D. Impact N0I-2. The revised project would not expose persons to or
generate excessive groundborne vibration.
The EIR finds that the revised project may generate vibration when heavy equipment or
impact tools (e.g., jackhammers, hydraulic demolition hammer/hoe ram) are used. The
revised project construction activities, such as pile driving, drilling, the use of
jackhammers, rock drills and other high-power or vibratory tools, and rolling stock
equipment (tracked vehicles, compactors, etc.), may generate substantial vibration in
the immediate vicinity.
Implementation of MM N0I-2.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the impact to a less than significant level by
restricting construction noise/vibration exposure, implementing measure to minimize
vibration, monitoring effects (if necessary), and notifying receptors.
MM N0I-2.1: Where vibration levels due to construction activities under the revised project
would exceed 0.3 in/sec PPV at nearby sensitive uses, development shall:
• Comply with the construction noise ordinance to limit hours of exposure. The City's
Municipal Code allows construction noise to exceed limits discussed in Section 10.48.040
during daytime hours. Certain types of construction are prohibited on weekends and all
holidays pursuant to Municipal Code Sections 10.48.053(B), (C) and (D).12
12 Municipal Code Section 10.48.053(B): Notwithstanding Section 10.48.053A, it is a violation
of this chapter to engage in any grading, street construction, demolition or underground utility
work within seven hundred fifty feet of a residential area on Saturdays, Sundays and holidays,
and during the nighttime period, except as provided in Section 10.48.030. Municipal Code
Section 10.48.053(C): Construction, other than street construction, is prohibited on holidays,
except as provided in Sections 10.48.029 and 10.48.030. Municipal Code Section 10.48.053(D):
• In the event pile driving would be required, all receptors within 300 feet of the project site
shall be notified of the schedule a minimum of one week prior to its commencement. The
contractor shall implement "quiet" pile driving technology (such as pre -drilling of piles,
the use of more than one pile driver to shorten the total pile driving duration, or the use
of portable acoustical barriers), in consideration of geotechnical and structural
requirements and conditions.
• To the extent feasible, the project contractor shall phase high -vibration generating
construction activities, such as pile driving/ground-impacting operations, so they do not
occur at the same time with demolition and excavation activities in locations where the
combined vibrations would potentially impact sensitive areas.
• The project contractor shall select demolition methods not involving impact tools, where
possible (for example, milling generates lower vibration levels than excavation using
clam shell or chisel drops).
• The project contractor shall avoid using vibratory rollers and packers near sensitive
areas.
• Impact pile driving shall be prohibited within 90 feet of an existing structure
surrounding the project site. Vibratory pile driving shall be prohibited within 60 feet of
an existing structure surrounding the project site.
• Prohibit the use of heavy vibration -generating construction equipment, such as vibratory
rollers or clam shovel, within 20 feet of any adjacent sensitive land use.
• If pile driving is required in the vicinity of vibration -sensitive structures adjacent to the
project site, survey conditions of existing structures and, when necessary, perform site-
specific vibration studies to direct construction activities. Contractors shall continue to
monitor effects of construction activities on surveyed sensitive structures and offer repair
or compensation for damage.
• Construction management plans for substantial construction projects, particularly those
involving pile driving, shall include predefined vibration reduction measures, notification
requirements for properties within 200 feet of scheduled construction activities, and
contact information for on-site coordination and complaints.
Construction, other than street construction, is prohibited during nighttime periods unless it
meets the nighttime standards of Section 10.48.040.
E. Impact UTIL-2. The revised project would require improvements to the
existing sewer system, however, the construction of the improvements
would not cause significant environmental effects.
The EIR finds that the revised project would generate an estimated net increase of 0.59
mgd of sewage. Development of the project would exceed the current capacity of the
12-,15-, and 27 -inch sewer mains serving the site. In addition, Cupertino Sanitary
District flows with flows from the project would exceed the peak flow of 13.8 mgd of
the City of Santa Clara interceptor located downstream of the project site.
Implementation of MM UTIL-2.1, MM UTIL-2.2, and MM UTIL-2.3, set forth below,
which are hereby adopted and incorporated into the project, would mitigate the project
impact to the sewer system by making improvements to the sewer system in order to
adequately convey flows from future development. The impact would be reduced to a
less than significant level.
MM UTIL-2.1: Future development under the revised project shall replace the existing 12- and
15 -inch sewer mains in Wolfe Road with new mains of an adequate size as determined by CuSD,
or shall install an 18- to 21 -inch parallel pipe to the existing 12- and 15 -inch mains to
accommodate existing and project flows.
MM UTIL-2.2: Future development under the revised project shall replace the existing 27 -inch
sewer main in Wolfe Road and Homestead Road with new mains of an adequate size determined
by the CuSD, or install a parallel pipe of an adequate size to the existing 27 -inch sewer main as
determined by CuSD.
MM UTIL-2.3: No building permits shall be issued by the City for structures or units that
would result in the permitted peak wet weather flow capacity of 13.8 mgd through the Santa
Clara sanitary sewer system being exceeded. The Developer may demonstrate, to the satisfaction
of the City and CuSD, that the project will not exceed the peak wet weather flow capacity of the
Santa Clara sanitary sewer system by implementing one or more of the following methods: 1)
Reduce inflow and infiltration in the CuSD system to reduce peak wet weather flows; 2) Increase
on-site water reuse, such as increased grey water use, or reduce water consumption of the
fixtures used within the project, or other methods that are measurable and reduce sewer
generation rates to acceptable levels, to the satisfaction of the CuSD; or 3) Revise the prior
agreement between CuSD and the City of Santa Clara to increase the permitted peak wet
weather flow to provide capacity for any development that would exceed the capacity of the
system. The estimated sewage generation by the revised project shall be calculated using the
sewer generation rates used by the San Jose - Santa Clara Water Pollution Control Plant Specific
Use Code & Sewer Coefficient table, and from the City of Santa Clara Sanitary Sewer Capacity
Assessment, May 2007,13 unless alternative (i.e., lower) sewer generation rates achieved by
future development are substantiated by the developer based on evidence to the satisfaction of the
CuSD.
VII. SIGNIFICANT AND UNAVOIDABLE CUMULATIVE IMPACTS WITH
MITIGATION INCORPORATED
An EIR is required to discuss the cumulative impacts of a project when the project's
incremental effect is cumulatively considerable. CEQA Guidelines § 15130(a)(1).
"Cumulatively considerable" means that the incremental effects of the project are
significant when viewed in connection with the effects of past projects, other current
projects, and probable future projects. CEQA Guidelines § 15065(a)(3); Pub. Resources
Code § 21083(b)(2). The Final EIR analyzes the cumulative impacts of the project in
combination with reasonably foreseeable probable future projects, which are listed in
Table 2.6-1 of the Draft EIR.
The Final EIR identifies the following significant and unavoidable adverse cumulative
impacts associated with the approval of the Vallco Special Area Specific Plan Project,
some of which can be reduced, although not to a less -than -significant level, through
implementation of mitigation measures identified in the EIR. Pub. Resources Code §
21081(a)(1). For the same reasons discussed in Section V, above, some impacts will
remain significant and unavoidable notwithstanding the adoption of feasible mitigation
measures. To the extent that these mitigation measures will not mitigate or avoid all
significant effects on the environment, and because the City cannot require mitigation
measures that are within the responsibility and jurisdiction of other public agencies to
be adopted or implemented by those other agencies, it is hereby determined that these
significant and unavoidable adverse impacts are acceptable for the reasons specified in
Section XI, below. Pub. Resources Code §21081(a)(3). As explained in Section XII, below,
the findings in this Section are based on the Draft EIR, the EIR Amendment, and the
Final EIR, the discussion and analysis in which is hereby incorporated in fully by this
reference.
13 The average dry weather sewerage generation rates used by the San Jose - Santa Clara Water
Pollution Control Plant Specific Use Code & Sewer Coefficient table, and the City of Santa
Clara Sanitary Sewer Capacity Assessment, May 2007, for the different uses within the project
are as follows: High Density Residential = 121 gpd/unit; Commercial/Retail = 0.076 gpd/SF;
Commercial/Restaurant = 1.04 gpd/SF; Office = 0.1 gpd/SF; Hotel = 100 gpd/Room; Civic
Space (office) = 0.21 gpd/SF; Adult Education = 15 gpd/Person; and Civic Space (Auditorium) _
0.11 gpd/SF.
A. Impact AQ -9. Implementation of the revised project would
cumulatively contribute to cumulatively significant air quality impacts
in the San Francisco Bay Area Air Basin.
The EIR finds that the revised project would result in significant and unavoidable
operational emissions (see Impact AQ -3) and would result in significant and
unavoidable cumulative air quality impacts to the region's existing air quality
conditions.
Implementation of MM AQ -9.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the impact but not to a less than significant
level. Therefore, this impact is considered a significant and unavoidable cumulative
impact.
MM AQ -9.1: Implement MM AQ -3.1.
B. Impact NOI-6. The revised project would result in a cumulatively
considerable permanent noise level increase at existing residential land
uses.
The EIR finds that the revised project would result in significant cumulatively
considerable permanent noise level increase at existing residential land uses. The
project would substantially increase cumulative traffic noise levels along several
roadway segments on the project site and surrounding area. The project's contribution
would be one dBA CNEL, which is considered a significant cumulative traffic noise
impact.
Additionally, along Perimeter Road north of Stevens Creek Boulevard, an increase of
seven to eight dBA was calculated under the cumulative plus project. The speed limit is
expected to remain 15 mph in the future, and the eight -foot sound wall is expected to
remain under future cumulative plus project condition. However, given that the
increase is expected to exceed five dBA CNEL compared to existing conditions and the
project's contribution to the increase is more than one dBA CNEL, a cumulatively
considerable contribution to the overall traffic noise increase at the adjacent existing
residential land uses would occur under the project and each alternative. This is a
significant cumulative impact.
Implementation of MM NOI-6.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the cumulatively considerable contribution
to a significant permanent cumulative noise impact at existing residences, but not to a
less than significant level. The existing sound wall and sound insulation features of the
existing residences may not change as a result of the project. Additionally, due to the 15
mph speed limit along Perimeter Road, quiet pavement and the installation of speed
bumps may not reduce the noise level increase to a less than significant level on this
street. Therefore, this impact is considered a significant and unavoidable cumulative
impact.
MM NOI-6.1: Implement MM NOI-3.1 to reduce project -generated noise level increases on
Perimeter Road north of Stevens Creek Boulevard and Vallco Parkway east of North Wolfe Road.
C. Impact TRN-6. The revised project would conflict with adopted
policies, plans, or programs regarding public transit, bicycle, or
pedestrian facilities or otherwise decrease the performance of safety of
such facilities.
The EIR finds that the revised project would result in delays to transit services in the
area for existing with project conditions, background with project conditions, and
cumulative with project conditions. These delays are caused by any roadway or
intersection geometry changes proposed by the project, taking into account unique
considerations of transit vehicles compared to autos, and automobile congestion caused
by the project and any changes to signal operations proposed by the project.
Implementation of MM TRN-6.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the cumulative impact, but not to a less
than significant level. Therefore, this impact is considered a significant and unavoidable
cumulative impact.
MM TRN-6.1: The VTA's VTP 2040 identifies the Stevens Creek Bus Rapid Transit project
(VTP ID T4) as an improvement near the project site. Ultimately, the VTP ID T4 would
enhance travel choice for the revised project and make more efficient use of the transportation
network. Thus, future development under the revised project would be required to contribute its
fair -share contribution of $4,832,000.00 to VTP ID T4.
The impact would remain significant and unavoidable, however, because the
implementation of the VTP projects are within the responsibility and jurisdiction of
another agency and the City cannot guarantee the improvement would be implemented
concurrent with the revised project.
D. Impact TRN-7. The revised project would result in a cumulatively
considerable contribution to a significant cumulative transportation
impact.
The EIR finds that the revised project would result in significant intersection level of
service impacts under cumulative with project conditions, defined as cumulative
conditions plus traffic generated by the buildout of the project and transportation
network infrastructure proposed by the project, at the following 18 intersections:
2. Stevens Creek Boulevard/SR 85 Northbound Ramps (east) (City of Cupertino)* -
AM peak hour;
8. De Anza Boulevard/Homestead Road (City of Cupertino) * - PM peak hour;
11. De Anza Boulevard/Stevens Creek Boulevard (City of Cupertino) - PM peak
hour;
12. De Anza Boulevard/McClellan Road/Pacifica Drive (City of Cupertino) - PM
peak hour;
23. Wolfe Road/Fremont Avenue (City of Sunnyvale) - PM peak hour;
26. Wolfe Road/Homestead Road (City of Cupertino) - PM peak hour;
31. Wolfe Road/Vallco Parkway (City of Cupertino) - PM peak hour;
32. Wolfe Road -Miller Avenue/Stevens Creek Boulevard (City of Cupertino)* - AM
and PM peak hours;
42. Stevens Creek Boulevard/Tantau Avenue (City of Cupertino) - AM peak hour;
43. Stevens Creek Boulevard/Stern Avenue (City of Santa Clara) - AM and PM peak
hours;
44. Stevens Creek Boulevard/Calvert Drive/I-280 Ramps (west) (City of Santa Clara)*
- AM and PM peak hours
45. Stevens Creek Boulevard/Agilent Driveway (City of Santa Clara) - AM peak
hour;
48. Lawrence Expressway/Homestead Road (Santa Clara County)* - PM peak hour;
51. Lawrence Expressway/Calvert Drive -I-280 Southbound Ramp (City of San Jose)*
- AM peak hour;
53. Lawrence Expressway/Bollinger Road (Santa Clara County)* - AM and PM peak
hour;
55. Lawrence Expressway/Prospect Road (Santa Clara County)* - AM peak hour;
60. Stevens Creek Boulevard/Cabot Avenue (City of Santa Clara) - PM peak hour;
and
66. Lawrence Expressway/Reed Avenue -Monroe Street (Santa Clara County) - PM
peak hour.
The revised project would also result in a significant freeway level of service impacts
under cumulative with project conditions at 15 mixed flow lanes in the AM peak hour,
22 mixed flow lanes in the PM peak hour, 12 HOV lanes in the AM peak hour, and eight
HOV lanes in the PM peak hour.
Implementation of MM TRN-7.1, MM TRN-7.2, MM TRN-7.3, MM TRN-7.4, MM TRN-
7.5, MM TRN-7.6, MM TRN-7.7, MM TRN-7.8, MM TRN-7.9, MM TRN-7.10, MM TRN-
7.11, MM TRN-7.12, MM TRN-7.13, MM TRN-7.14, MM TRN-7.15, and MM TRN-7.16,
set forth below, which are hereby adopted and incorporated into the project, would
reduce the cumulative impact, but not to a less than significant level. Therefore, this
impact is considered a significant and unavoidable cumulative impact.
MM TRN-7.1: Implement MM TRN-1.1.
The TDM program is expected to reduce the severity of intersection and freeway
impacts, although not necessarily to a less than significant level.
MM TRN-7.2: Intersection 2, Stevens Creek Boulevard/SR 85 northbound ramps: The City's
TIF Program identifies the addition of an exclusive northbound left -turn lane from the SR 85 off -
ramp onto westbound Stevens Creek Boulevard.
This improvement would mitigate the revised project's impact to a less than significant
level. Future development under the revised project shall pay transportation mitigation
fees as calculated pursuant to the TIF program to mitigate this impact. However,
because the TIF improvements are not fully funding and the timing of implementation
is not known at this time, the impact to Intersection 2 is considered significant and
unavoidable.
MM TRN-7.3: Intersection 8, De Anza Boulevard/Homestead Road: The City's TIF Program
identifies the widening of De Anza Boulevard to four through lanes between the I-280
interchange and Homestead Road.
This improvement would mitigate the revised project's impact to a less than significant
level. Future development under the revised project shall pay transportation mitigation
fees as calculated pursuant to the TIF program to mitigate this impact. However,
because the TIF improvements are not fully funding and the timing of implementation
is not known at this time, the impact to Intersection 8 is considered significant and
unavoidable.
MM TRN-7.4: Intersection 12, De Anza Boulevard/McClellan Road: Implement MM TRN-
1.2.
Implementation of MM TRN-1.2 would improve intersection operations to better than
cumulative (without) revised project conditions. However, because the TIF
improvements are not fully funded and the timing of implementation is not known at
this time, the impact is considered significant and unavoidable.
MM TRN-7.5: Intersection 23, Wolfe Road/Fremont Avenue: Provide a dedicated southbound
right -turn lane from Wolfe Road onto westbound Fremont Avenue.
The intersection would continue to operate at unacceptable LOS E under the project,
but the delay would be reduced to a level lower than cumulative conditions. Thus, the
impact would be mitigated to a less than significant level.
The City of Sunnyvale recently approved improvements to the "Triangle" area of Wolfe Road/EI
Camino Real, Wolfe Road/Fremont Avenue, and El Camino Real/Fremont Avenue. The
"Triangle" improvements include the provision of a southbound right -turn lane from Wolfe
Road to Fremont Avenue. Thus, future development under the revised project would be required
to contribute their fair -share contribution of $527,000.00 to the "Triangle" improvement project.
The impact would remain significant and unavoidable, however, because the
intersection is within the responsibility and jurisdiction of another agency and the City
cannot guarantee the improvement would be constructed concurrent with the proposed
project.
MM TRN-7.6: Intersection 26, Wolfe Road/Homestead Road: Provide a dedicated southbound
right -turn lane from Wolfe Road onto westbound Homestead Road. To minimize secondary
impacts to pedestrian travel, the right -turn lanes would need to be signal controlled, right -turns
on red would be prohibited, and pedestrians should have a leading pedestrian phase (i.e., a
pedestrian walk indication is provided several seconds before the right -turning vehicle traffic).
This mitigation measures would improve intersection operations but not to a less than
significant level.
The City's TIF Program includes the provision of the dedicated southbound right -turn
lane. Future development under the revised project shall pay transportation mitigation
fees as calculated pursuant to the TIF program to mitigate this impact. However,
because the TIF improvements are not fully funding and the timing of implementation
is not known at this time, the impact to Intersection 26 is considered significant and
unavoidable.
MM TRN-7.7: Intersection 31, Wolfe RoadlVallco Parkway: Implement MM TRN-2.3.
Implementation of this measure would mitigate the revised project's cumulative impact
to a less than significant level.
MM TRN-7.8: Intersection 42, Stevens Creek BoulevardlTantau Avenue: Implement MM
TRN-2.4.
Because the TIF improvements are not fully funding and the timing of implementation
is not known at this time, the impact is considered significant and unavoidable.
MM TRN-7.9: Intersections 43-45: Implement MM TRN-2.5.
As discussed under Impact TRN-2, implementation of this measure would reduce the
revised project's impact but not to a less than significant level.
MM TRN-7.10: Intersection 48, Lawrence ExpresswaylHomestead Road: Implement MM
TRN-2.6. As discussed under MM TRN-2.6, the revised project shall pay a fair -share
contribution of $291,000.00 to the long-term improvement identified in the Santa Clara
County's Expressway Plan 2040 Study for this intersection.
The impact would remain significant and unavoidable, however, because the
intersection is within the responsibility and jurisdiction of another agency and the City
cannot guarantee the improvement would be constructed concurrent with the proposed
project.
MM TRN-7.11: Intersection 51, Lawrence ExpresswaylCalvert Drive -I-280 Southbound Ramp:
Implement MM TRN-2.7.
The impact is significant and unavoidable because the feasibility of the improvement is
yet to be determined, the impact would remain significant and unavoidable, and
because the intersection is within the responsibility and jurisdiction of another agency
and the City cannot guarantee the improvement would be constructed concurrent with
the proposed project.
MM TRN-7.12: Intersection 53, Lawrence Expressway/Bollinger Road: Implement MM TRN-
2.8.
Implementation of this measure would improve intersection operations to an acceptable
LOS E or better. The impact would remain significant and unavoidable, however,
because the intersection is within the responsibility and jurisdiction of another agency
and the City cannot guarantee the improvement would be constructed concurrent with
the proposed project.
MM TRN-7.13: Intersection 60, Stevens Creek Boulevard/Cabot Avenue: Contribute a fair -
share contribution of $23,000.00 to a traffic signal timing study and implementation of the
revised timings on Stevens Creek Boulevard at Cabot Avenue.
The revised project impact would likely improve with modifications to the signal
timings as traffic volumes change. The impact would be significant and unavoidable,
however, because the effectiveness of the improvement would be determined through
the signal timing study and because the intersection is within the responsibility and
jurisdiction of another agency and the City cannot guarantee the implementation of the
signal timing study.
MM TRN-7.14: Intersection 38, Tantau AvenuelHomestead Road: Restripe the southbound
approach (Quail Avenue) to provide a separate left -turn lane and shared throughlright-turn lane
(including removal of on -street parking).
This improvement is included in the City's TIF Program and would improve
intersection operations to an acceptable LOS D. Future development under the revised
project shall pay transportation mitigation fees as calculated pursuant to the TIF
program to mitigate this impact. However, because the TIF improvements are not fully
funded and the timing of implementation is not known at this time, the impact is
considered significant and unavoidable.
MM TRN-7.15: Implement MM TRN-1.3.
The VTP 2040 projects will enhance vehicular travel choices for the project (and project
alternatives), and make more efficient use of the transportation roadway network, and
the SR 85 Transit Guideway Study will help improve transit options in the SR 85
corridor. These freeway operations enhancements would not improve all impacted
freeway segments to less than significant levels, however. The TDM Program proposed
under the revised project and mitigation measure MM TRN-7.1 would reduce project -
generated vehicle trips, thereby reducing the revised project impact on freeway
segments, but it is not anticipated that the freeway impacts would be reduced to a less
than significant level. For the above reasons, the revised project would remain
significant and unavoidable with the implementation of MM TRN-7.1 and -7.15.
MM TRN-7.16: Intersection 3, Stevens Creek Boulevard/Stelling Road: Provide an additional
second eastbound left -turn lane from Stevens Creek Boulevard onto northbound Stelling Road.
This mitigation measure would improve intersection operations to an acceptable LOS
D.
The City's TIF Program identifies the addition of a second eastbound left -turn lane from
Stevens Creek Boulevard onto northbound Stelling Road as a General Plan Mitigation
Measure. Future development under the revised project shall pay transportation
mitigation fees as calculated pursuant to the TIF program to mitigate this impact.
However, because the TIF improvements are not fully funded and the timing of
implementation is not known at this time, the impact is considered significant and
unavoidable.
VIII. SIGNIFICANT ADVERSE CUMULATIVE IMPACTS IDENTIFIED IN THE
FINAL EIR THAT ARE REDUCED TO A LESS -THAN -SIGNIFICANT LEVEL
BY MITIGATION MEASURES ADOPTED AND INCORPORATED INTO
THE PROJECT
The Final EIR identifies the following significant cumulative impacts associated with
the revised project. It is hereby determined that the cumulative impacts addressed by
these mitigation measures will be mitigated to a less than significant cumulative level or
avoided by adopting and incorporating these mitigation measures into the project. The
findings in this section are based on the Draft EIR, EIR Amendment, and Final EIR, the
discussion and analysis in which is hereby incorporated in full by this reference.
A. Impact CR -4. The revised project would not result in a cumulatively
considerable contribution to a significant cumulative cultural resources
impact.
The EIR finds that the development of cumulative projects in proximity to the project
site, in conjunction with the development of the revised project could significantly
impact unknown buried archaeological resources. The cumulative projects are required
to comply with federal, state, and local regulations put in place to protect cultural
resources.
Implementation of MM CR -4.1, set forth below, which is hereby adopted and
incorporated into the project, would avoid and/or minimize impacts to buried cultural
resources to a less than significant level. Thus, the revised project would not have a
cumulatively considerable contribution to a significant cumulative cultural resources
impact.
MM CR -4.1: Implement MM CR -2.1 through MM CR -2.4.
B. Impact GHG-1. The revised project would not generate cumulatively
considerable GHG emissions that would result in a significant
cumulative impact to the environment.
The EIR finds that the revised project would result in construction -related GHG
emissions. The revised project will have annual GHG emissions of 3.5
MTCO2e/year/service population, which exceeds the significance threshold of 2.6
MTCO2e/year/service population.
Implementation of MM GHG-1.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the project emissions impact to a less than
significant level by implementing a GHG Reduction Plan that would offset and/or
reduce GHG emission to below the significance threshold.
MM GHG-1.1: Under the revised project, the project proponent shall prepare and implement a
GHG Reduction Plan to offset the revised project -related incremental increase of greenhouse gas
emissions resulting in the exceedance of the significance threshold of 2.6 MTCO2e/year/service
population. Refinement of the estimated GHG emissions from the revised project shall be
completed as part of the GHG Reduction Plan in order to reflect the most current and accurate
data available regarding the project's estimated emissions (including emission rates). The GHG
Reduction Plan shall include the implementation of a qualifi/ing TDM program to reduce mobile
GHG emissions. Additional offsets and reductions may include, but are not limited to, the
following:
• Construct on-site or fund off-site carbon sequestration projects (such as a forestry or
wetlands projects for which inventory and reporting protocols have been adopted). If the
revised project develops an off-site project, it must be registered with the Climate Action
Reserve or otherwise approved by BAAQMD in order to be used to offset project (or
project alternative) emissions; and/or
Purchase of carbon credits to offset revised project annual emissions. Carbon offset
credits shall be verified and registered with The Climate Registry, the Climate Action
Reserve, or another source approved by CARB or BAAQMD. The preference for offset
carbon credit purchases include those that can be achieved as follows: 1) within the City;
2) within the San Francisco Bay Area Air Basin; 3) within the State of California, then 4)
elsewhere in the United States. Provisions of evidence of payments, and ficnding of an
escrow -type account or endowment fund would be overseen by the City.
C. Impact HAZ-6. The revised project would not have a cumulatively
considerable contribution to a significant cumulative hazardous
materials impact.
The EIR finds that the revised project could result in significant cumulative
environmental impacts because of existing conditions in the geographic area that could
lead to the exposure of people and the environment to hazardous materials.
The geographic area for cumulative hazards and hazardous materials impacts includes
the project site and the surrounding area. Some of the projects included in the
cumulative analysis are proposed on properties that were previously developed with
industrial or commercial uses. It is likely that hazardous materials may have been
stored and used on, and/or transported to and from, some of these properties as part of
activities on the sites. In addition, many of the properties in Cupertino and surrounding
cities were used for agricultural purposes prior to their urban development and
agricultural chemicals, such as pesticides and fertilizers, may have been used on these
sites in the past. The use of these chemicals can result in residual soil contamination,
sometimes in concentrations that exceed regulatory thresholds. Further, development
and redevelopment of some of the cumulative projects sites would require demolition
of existing buildings that may contain lead-based paint and/or ACMs. Demolition of
these structures could expose construction workers or other persons in the vicinity to
harmful levels of lead and/or ACMs.
Implementation of MM HAZ-6.1, set forth below, which is hereby adopted and
incorporated into the project, would reduce the project impact to a less than significant
level. With the inclusion of development -specific mitigation and compliance with
existing statutes and regulations, the cumulative projects and revised project would not
result in significant cumulative hazardous materials impacts.
MM HAZ-6.1: Implement MM HAZ-1.1 through -1.4.
IX. GROWTH INDUCING IMPACTS
An EIR is required to discuss growth inducing impacts, which consist of the ways in
which the project could foster economic or population growth, or the construction of
additional housing, either directly or indirectly, in the surrounding environment. CEQA
Guidelines § 15126.2(d); Pub. Resources Code § 21100(b)(5). Direct growth inducement
would result, for example, if a project involves the construction of substantial new
housing that would support increased population in a community or establishes
substantial new permanent employment opportunities. This additional population
could, in turn, increase demands for public utilities, public services, roads, and other
infrastructure. Indirect growth inducement would result if a project stimulates
economic activity that requires physical development or removes an obstacle to growth
and development (e.g., increasing infrastructure capacity that would enable new or
additional development). It must not be assumed that growth in any area is necessarily
beneficial, detrimental, or of little significant to the environment. State CEQA
Guidelines §15126.2(d). Section 4.0 of the Draft EIR analyzes the growth inducing
impacts of the Vallco Special Area Specific Plan. As explained in Section XII, below, the
findings in this Section are based on the Draft EIR, the EIR Amendment, and Final EIR,
the discussion and analysis in which is hereby incorporated in full by this reference.
A. Direct Growth Inducement
The project would result in direct economic growth because the proposed uses include
new employment, and other land uses that generate tax revenues for public services.
The project would also result in direct population growth. However, the residential
population growth from the project would not constitute substantial population growth
in the area because it would occur on an infill site, is consistent with General Plan goals
for focused and sustainable growth, and supports the intensification of development in
an urbanized area currently served by existing roads, transit, utilities, and public
services. The revised project would allow 1,399 more residential units than anticipated
with the buildout of the City's General Plan, but these additional units are within the
Plan Bay Area Projections for the City and County. The projected number of employees
from the project are anticipated in the citywide buildout of the General Plan. Thus, the
direct impact would be less than significant.
B. Indirect Growth Inducement
The project would not result in significant indirect growth -inducing impacts. The
project site is located in an urbanized, infill site that is served by existing infrastructure,
including roadways and utilities. The growth that could result from development
consistent with the specific plan could tax existing community service facilities. The
project includes infrastructure improvements to mitigate the impacts on community
service facilities to a less than significant level. Utility improvements would be sized to
serve the proposed development and would not have excess capacity. Thus, the utility
improvements would not remove obstacles to population growth. In addition, the
project would pay all applicable impact fees and taxes, which would offset impacts to
public facilities and services, including police and fire, schools, and parks. As a result,
growth associated with the implementation of the project would not have a significant
impact on community service facilities, nor would it make a cumulatively considerable
contribution to such impacts, requiring construction of new facilities that could cause
significant environmental effects. Thus, the indirect impact would be less than
significant.
X. ALTERNATIVES
The Draft EIR analyzed four alternatives to the previous project (including the No
Project Alternative), and the EIR Amendment analyzed a fifth alternative (the Housing
Rich Alternative). The previous project was revised in the Final EIR (the "revised
project"); therefore, the Final EIR analyzed the revised project, the previous project, four
development alternatives, and the No Project Alternative, and compared the
alternatives to the revised project as required by CEQA Guidelines Section 15126.6. The
alternatives are briefly summarized below and described in Section 7.0 of the Draft EIR,
the Sections 3.0 and 8.1 of the EIR Amendment, and Table 2.1-12 and Section 6.0 (Text
Revisions) of the Final EIR. Brief summaries of the evaluated alternatives are provided
below. As explained in Section XII, below, the findings in this Section are based on the
Draft EIR, the EIR Amendment, and the Final EIR, the discussion and analysis in which
is hereby incorporated in full by this reference, and on the record as a whole.
A. No Project Alternative
CEQA requires consideration of a no project alternative. Consistent with the State
CEQA Guidelines, the No Project Alternative assumes the continuation of existing plans
and policies. Under the No Project Alternative, the project site could remain as it
currently exists (i.e., an existing shopping mall that is approximately 15 percent
occupied) with little or no change.
The No Project Alternative would not achieve any of the project objectives, which are
set forth in Section II, above, because it does not facilitate the development of the site
into a regional, mixed-use housing, multi -modal, sustainable development.
For the foregoing reasons, the No Project Alternative is hereby rejected.
B. Previous Project
The previous project is considered an alternative to the revised project. Consistent with
the adopted General Plan, the previous project would facilitate development of a
minimum of 600,000 square feet of commercial uses, up to 2.0 million square feet of office
uses, up to 339 hotel rooms, and up to 800 residential dwelling units on-site. The previous
project reflects the buildout assumptions (including the adopted residential allocation
available) for the site in the City's adopted General Plan. In addition, the previous project
includes up to 65,000 square feet of civic spaces in the form of governmental office space,
meeting rooms and community rooms and a Science Technology Engineering and
Mathematics (STEM) lab, as well as a 30 -acre green roof. Compared to the revised project,
the previous project proposes the same land uses but contains different amounts of
commercial, office, residential, and civic space development proposed. All other aspects
of the previous project (including on-site amenities, maximum building height, setbacks,
General Plan and zoning amendments, and other programming elements) are the same as
the revised project.
The previous project would be less effective in meeting project objective 2 of providing
adequate development capacity for more housing to meet the City's Regional Housing
Needs Allocation. The previous project would only provide 800 residential dwelling
units, which is significantly less housing compared to the revised project proposal for
2,923 residential units. The previous project would, therefore, also fail to address the
City's expressed desire to improve the jobs and housing balance, as discussed at the
Council's June 4, 2018 Study Session on the Vallco Specific Plan.
For the foregoing reasons, the previous project is hereby rejected.
C. General Plan Buildout with Maximum Residential Alternative
The General Plan Buildout with Maximum Residential alternative consists of the
potential development on the site if the residential portion of the project were
developed at the General Plan maximum allowable density of up to 35 du/ac. The
General Plan, however, controls residential development through an allocation system.
This alternative assumes that there are no residential allocation controls in place and
development can occur at the maximum density allowed by the General Plan. This
alternative assumes the same amount of commercial, hotel, civic, and green roof
development as the previous project, and a smaller amount of office development (1.0
million square feet) than the previous project.
While the General Plan Buildout with Maximum Residential Alternative would meet all
of the project objectives because the alternative includes a mix of uses (including
housing) and sales tax revenue generating commercial uses, and could create a multi-
modal, sustainable development, it would not meet the project objectives to the same
degree as the revised project because it would not provide all the community benefits
desired by the City Council as expressed in their comments at the June 4, 2018 study
session. The General Plan Buildout with Maximum Residential Alternative does not
include construction, or funding for construction, of a new City Hall.
For the foregoing reasons, the General Plan Buildout with Maximum Residential
Alternative is hereby rejected.
D. Retail and Residential Alternative
The Retail and Residential Alternative consists of developing the site without any office
use. The retail commercial component is assumed to be 600,000 square feet, and the
residential density is dependent on a preliminary economic feasibility analysis of
constructing this alternative.
While the Retail and Residential Alternative could meet all six of the project objectives
because the alternative includes a mix of uses (including housing) and sales tax revenue
generating commercial uses, and could create a multi -modal, sustainable development,
it would not meet the project objectives to the same degree as the revised project.
Although the Retail and Residential Alternative addresses the City's desire for further
housing, it does not provide community benefits. For the foregoing reasons, the Retail
and Residential Alternative is hereby rejected.
E. Occupied/Re-Tenanted Mall Alternative
The Occupied/Re-Tenanted Mall Alternative was discussed in response to the desire by
some members of the community to see the existing mall remain and be successfully
occupied/re-tenanted. It is assumed under this alternative that no new structures would
be constructed on-site and no modifications to the existing building layout and heights
would occur. Exterior and interior modifications would likely be made in order to
update the mall to current standards for aesthetics and lighting and Americans with
Disabilities Act (ADA) compliance. Because this alternative would not meet most of the
project objectives and would be economically infeasible, as discussed below, it is
discussed in the EIR for informational purposes only.
The Occupied/Re-Tenanted Mall Alternative would meet objective 4 of providing the
City with sales tax revenue. However, the Occupied/ Re -Tenanted Mall Alternative
would not meet objective 1 or 2 of creating a mixed-use Town Center and providing
housing. Because this alternative would not result in the redevelopment of the project
site, it would not meet objectives 5 and 6 of creating a multi -modal, sustainable
development. Therefore, the Occupied/Re-Tenanted Mall Alternative would not meet
most of the project objectives.
In addition, Occupied/Re-Tenanted Mall Alternative would be economically infeasible
for the reasons stated in the Vallco Special Area Real Estate Market Assessment completed
for this site in March 2018 by Economic & Planning Systems, Inc., which is incorporated
herein by reference. The Vallco Special Area Real Estate Market Assessment concludes that
retail reuse of the existing mall would be highly unlikely given its location between
well-established regional malls and lifestyle centers (e.g., Westfield Valley Fair, Santana
Row, Stanford Shopping Center, and Great Mall).14 This alternative, therefore, also does
not meet objective 3.
For the foregoing reasons, the Occupied/Re-Tenanted Mall Alternative is hereby
rejected.
F. Housing Rich Alternative
The Housing Rich Alternative was identified in response to community and City
interest in having a greater number of housing units with a greater than 15 percent
below -market -rate housing component and the inclusion of substantial community
amenities such as a performing arts center, civic space, educational space, a robust
transportation contribution, and enough office development on the site to support the
additional community amenities and the higher below-market rate component. The
Housing Rich Alternative consists of 3,250 residential units, 1.5 million square feet of
office uses, 600,000 square feet of commercial uses, 65,000 square feet of civic uses
(consisting of a 50,000 square foot City Hall and 15,000 square feet of adult education
space), and a 30 -acre green roof. It is estimated that the Housing Rich Alternative
would require approximately 13,880 parking spaces, most of which would be located
below ground. Excavation depths of approximately 20 to 50 feet would be required for
14 Economic & Planning Systems, Inc. Vallco Special Area Real Estate Market Assessment.
March 6, 2018. Pages 2-3.
below ground parking, which would result in approximately 2.1 million cubic yards of
soil being hauled off-site.
While the Housing Rich Alternative would meet all six of the project objectives
identified in the Draft EIR because the alternative includes a mix of used (including
housing) and sales tax revenue generating commercial uses, and could create a multi-
modal, sustainable development, it would not meet the project objectives to the same
degree as the revised project because it would not provide all the community benefits
desired by the City.
In addition, the Housing Rich Alternative would have greater environmental impacts
than the revised project. The Housing Rich Alternative would have higher annual
construction emissions than the revised project. As shown in Table 2.1-1 in the Final
EIR, the Housing Rich Alternative will produce more ROG and NO., emissions than the
revised project during construction (Impact AQ -2). The Housing Rich Alternative will
produce greater operational ROG emissions than the revised project (Impact AQ -3). As
shown in Table 2.1-3 in the Final EIR, the Housing Rich Alternative will have a greater
demand for natural gas than the revised project during operation (Impact EN -2). The
Housing Rich Alternative also would have slightly higher construction -related GHG
emissions than the revised project, as shown in Table 2.1-4 of the Final EIR (Impact
GHG-1). It will also produce greater average daily trips and PM peak hour. trips in
comparison to the revised project, as shown in Table 2.1-6 of the Final EIR, and higher
net sewage generation, water demand, and solid waste generation, as shown in Tables
2.1-8, 2.1-9, and 2.1-10 of the Final EIR (Impacts UTIL-1, UTIL-2, UTIL-3, UTIL-5, and
UTIL-6).
For the foregoing reason, the Housing Rich Alternative is hereby rejected.
G. Environmentally Superior Alternative
On the basis of the analysis of the Draft EIR, the City finds that the No Project
Alternative is the environmentally superior alternative. The No Project Alternative
would avoid all of the project's significant impacts. CEQA Guidelines Section
15126.6(e)(2), however, states that "if the environmentally superior alternative is the No
Project Alternative, the EIR shall also identify an environmentally superior alternative
among the other alternatives." Therefore, the Retail and Residential Alternative is the
environmentally superior alternative, because it would result in reduced impacts for the
alternative compared to the revised project for the following impacts: Impact AQ-,
Impact AQ -3, Impact AQ -4, Impact AQ -6, Impact AQ -9, Impact EN -1, Impact EN -3,
Impact GHG-1, Impact NOI-3, Impact NOI-6, Impact TRN-1, Impact TRN-2, Impact
TRN-6, Impact TRN-7, Impact UTIL-3, Impact UTIL-5, Impact UTIL-6, and Impact
UTIL-7.
XI. STATEMENT OF OVERRING CONSIDERATIONS
As set forth above, the City has found that some of the adverse environmental impacts
of the Vallco Special Area Specific Plan project remain significant following adoption
and implementation of mitigation measures described in the EIR and incorporated into
the Project. Section 15093(b) of the CEQA Guidelines provides that when the decision of
the public agency results in the occurrence of significant impacts that are not avoided or
substantially lessened, the agency must state in writing the reasons to support its
actions. Having balanced the benefits of the revised project against its significant and
unavoidable environmental impacts, the City finds that the project's benefits outweigh
its unavoidable adverse environmental effects, and that the adverse environmental
effects are therefore acceptable. The City further finds that each of the project benefits
discussed below is a separate and independent basis for these findings. The reasons set
forth below are based on the Final EIR and other information in the administrative
record.
A. The revised project will occur on an infill site in an existing urbanized area
in Cupertino, which will result in environmental benefits because it will
not directly or indirectly lead to development of greenfield sites in the San
Francisco Bay Area.
B. The revised project is consistent with the General Plan in that it will
increase the number of places to live within the Plan Area. The plan
supports infill development, conversion of vacant and outdated buildings,
and location of housing near employment centers to reduce the use of
single occupancy cars, increase commute choices reduce long commutes,
reduce the use of fossil fuels, improve energy efficiency, reduce carbon
dioxide emissions, and help meet air quality standards. Thus, the project
will further the General Plan goals expressed in Policies LU -1 through LU -
9 and Strategies LU -1.19.3 through LU -1.19.6 and LU -1.19.9 through LU -
1.19.9 through LU -1.19.1.14.
C. The revised project will meet and exceeds the City's Regional Housing
Needs Allocation (RHNA) of 1,064 units by providing 2,923 residential
units.
D. Twenty percent of the residential units will be affordable at the following
percentages: 15% will be a mix of units affordable at very low and low
income levels, and 5% will be affordable at a moderate income level.
E. The revised project will provide additional non -single occupancy
vehicular transportation opportunities under the Tier 2 Development
Program, including an approximately 1,000 square foot mobility hub with
bicycle facilities; funding of up to $1,000,000 for a one-year Pilot
Community Shuttle, with additional $750,000 per year for ongoing
operations if the project is successful; an areawide Transportation
Demand Management program which will be implemented by the
areawide Transportation Management Association that would provide
services to all users of the site and also ensure that office trips meet
specified caps with a goal of 34 percent non -single occupancy vehicle rate.-
and
ate;and a total of $11,000,000 to fund work on the 1-280/Wolfe Road
interchange and the Junipero Serra/Pedestrian Trail (a bike and pedestrian
trail along I-280).
F. The revised project will provide additional open space, including publicly
accessible pedestrian walkways, open space provided on the bridge over
Wolfe Road, and public park and plazas designed in accordance with the
Specific Plan.
G. The revised project will provide multiple civic improvements in the Plan
Area under the Tier 2 Development Program, including a "warm shell"
performing arts center for the City (or an in lieu payment of $22,8000,000,
if the City opts out); rebuilding existing City Hall (or if not approved and
available for construction within 24 months, an in lieu payment of
$30,000,000); providing a 25,000 square foot "warm shell" space for adult
school and high school innovation space to the Fremont Union High

$9,500,000 to Cupertino Union School District; and using good faith efforts
to provide approximately 40,000 square feet in co -working or incubator
space.
XII. INCORPORATION BY REFERENCE
These findings incorporate the text of the Final Program Environmental Impact Report
for the Vallco Special Area Specific Plan project by reference and in their entirety.
Without limitation, this incorporation is intended to elaborate on the scope and nature
of mitigation measures, the basis for determining the significance of impacts, the
comparative analysis of alternatives, the determination of the environmentally superior
alternative, and the reasons for approving the Project in spite of the potential for
associated significant and unavoidable adverse impacts.
XIII. RECIRCULATION NOT REQUIRED
No significant new information was added to the Draft EIR, the EIR Amendment, or the
Final EIR as a result of the public comment process. The Final EIR responds to
comments, and clarifies, amplifies, and makes insignificant modifications to the Draft
EIR and EIR Amendment. The Supplemental Text Revisions clarify, amplify and make
insignificant modifications to the Final EIR, including minor corrections to the text.
These clarifications, amplification and insignificant modifications do not identify any
new significant effects on the environment or a substantial increase in the severity of an
environmental impact requiring major revisions to the Draft EIR, the EIR Amendment
or the Final EIR. Similarly, the revised project would not result in new or substantially
more severe significant impacts than disclosed previously in the Draft EIR and EIR
Amendment. Therefore, recirculation of the EIR is not required.
XIV. RECORD OF PROCEEDINGS
Various documents and other materials related to the revised project constitute the
record of proceedings upon which the City bases its findings and decisions contained
herein. Those documents and materials are located in the offices of the custodian for the
documents and materials, which is the City of Cupertino Community Development
Department, Cupertino City Hall, 10300 Torre Avenue, Cupertino, CA 95014-3202.
XV. SUMMARY
A. Based on the foregoing Findings and the information contained in the
record, the City has made one of more of the following Findings with
respect to each of the significant effects of the Project:
Changes or alterations have been required in, or incorporated into,
the Project that avoid or substantially lessen the significant
environmental effects identified in the Final EIR.
2. Those changes or alterations are within the responsibility and
jurisdiction of another public agency and have been, or can and
should be, adopted by that other public agency.
3. Specific economic, legal, social, technological, or other
considerations, make infeasible the mitigation measures or
alternatives identified in the Final EIR that would otherwise avoid
or substantially lessen the identified significant environmental
effects of the Project.
B. Based on the foregoing Findings and the information contained in the
record, the City determines that:
1. All significant effects on the environment due to the approval of the
Project have been eliminated or substantially lessened where
feasible.
2. Any remaining significant effects on the environment found to be
unavoidable are acceptable due to the factors described in the
Statement of Overriding Considerations, above.
EXHIBIT EA -2
MITIGATION MONITORING OR REPORTING PROGRAM
Vallco Town Center Specific Plan
CITY OF CUPERTINO
September 2018
PREFACE
Section 21081 of the California Environmental Quality Act (CEQA) requires a Lead Agency to adopt a Mitigation Monitoring or
Reporting Program whenever it approves a project for which measures have been required to mitigate or avoid significant
effects on the environment. The purpose of the monitoring or reporting program is to ensure compliance with the mitigation
measures during project implementation.
On September X, 2018, the City Council certified the Environmental Impact Report (EIR) for the Vallco Special Area Specific
Plan project. The Final EIR concluded that the implementation of the project could result in significant effects on the
environment and mitigation measures were adopted and incorporated into the project or are required as a condition of project
approval. This Mitigation Monitoring or Reporting Program addresses those measures in terms of how and when they will be
implemented.
The attached table includes columns that show: 1) each mitigation measure identified in the Final EIR as finally adopted; 2) the
procedure for implementing each mitigation measure, 3) the City entity responsible and procedure for monitoring and
reporting implementation of each mitigation measure; and 4) the timing for implementation of each mitigation measure.
In addition, this Mitigation Monitoring or Reporting Program lists Standard Permit Conditions, which are measures required
to comply with laws and regulations, and City Conditions of Approval, for purposes of tracking responsibility for and timing
of implementation of each, even though these conditions are not mitigation measures.
This document does not discuss those subjects for which the EIR concluded that mitigation measures would not be required to
reduce significant impacts.

17. The project shall develop a plan demonstrating
that the off-road equipment (more than 25
horsepower) to be used in the construction
project (i.e., owned, leased, and subcontractor
vehicles) would achieve a minimum project wide
fleet -average 25 percent NO. reduction and 65
percent PM (particulate matter) exhaust
reduction compared to the CalEEMod modeled
average used in this report. Acceptable options
for reducing emissions include the use of late
model engines, low -emission diesel products,
alternative fuels, engine retrofit technology,
after -treatment products, add-on devices such as
particulate filters, and/or other options as such
become available. The following are feasible
methods:
• All construction equipment larger than 25
horsepower used at the site for more than two
continuous days or 20 hours total shall meet
EPA Tier 4 emission standards for NO. and
PM, where feasible.
