II. SummaryII. SUMMARY
A. PROJECT UNDER REVIEW
In compliance with the California Environmental Quality Act (CEQA), this Draft EIR describes the
environmental consequences of the Apple Campus 2 Project (project). This Draft EIR is designed to
fully inform decision -makers in the City of Cupertino, other responsible and trustee agencies, and the
general public of the potential environmental consequences of the proposed project. The project
sponsor is Apple Inc.
The City of Cupertino (City) is the lead agency for environmental review of the Apple Campus 2
Project. This EIR will be used by City staff, responsible agencies, and the public in their review of the
proposed project.
The proposed project would replace and redevelop an approximately 176 -acre project site, consisting
of an area generally bordered by East Homestead Road on the north; adjacent properties to the east of
North Tantau Avenue on the east; Interstate 280 (I-280) and The Hamptons apartment community on
the south; and North Wolfe Road on the west. Pruneridge Avenue extends through the site on a
roughly east/west alignment. The project site currently contains approximately 2,657,000 feet of
office and research and development buildings, some of which are occupied by Apple and formerly
used by Hewlett-Packard. Calabazas Creek crosses the southeastern portion of the site.
The project would result in the demolition of all structures within the project site (consisting of
approximately 2,657,000 square feet of building space) and the ultimate construction of 3,420,000
square feet of office, research, and development uses; 245,000 square feet of auditorium, fitness
center, and Valet Parking Reception uses; 92,000 square feet of utility plants; and parking and
ancillary buildings (such as security receptions and landscape maintenance buildings). In addition,
Apple is requesting that a segment of Pruneridge Avenue be vacated by the City to allow for the
development of a secure and unified campus. Development of the proposed project would require
amendments to the City of Cupertino General Plan, and Zoning Ordinance, Vacation and Land
Purchase Agreement, Utility Relocation and Easement Agreements, architectural and site approval,
and various other City entitlements, possibly including a Development Agreement. The proposed
project could require additional discretionary permits or approvals from other non -City governmental
entities. A detailed description of the proposed project is provided in Chapter III, Project Description.
B. SUMMARY OF IMPACTS AND MITIGATION MEASURES
This summary provides an overview of the analysis contained in Chapter V, Setting, Impacts, and
Mitigation Measures. CEQA requires a summary to include a discussion of. (1) potential areas of
controversy; (2) significant project -level impacts; (3) cumulative impacts; (4) significant irreversible
and unavoidable impacts; and (5) alternatives to the proposed project that would reduce or avoid the
environmental impacts of the project. A summary is also required to discuss issues to be resolved,
including the choice among alternatives, and whether or how to mitigate significant environmental

effects. However, a summary is not a substitute for reviewing the full EIR in order to understand a
particular topic. The reader is referred to the main body text of the EIR for detailed discussions about
the existing environmental setting of the project, project impacts, and project mitigation measures.
1. Potential Areas of Controversy
Letters and verbal testimony (from the September 9, 2011, scoping session) received as comments on
the Notice of Preparation (NOP) raised a number of potential areas of controversy, including impacts
related to public space and access, the Glendenning Barn, schools, utilities and public services
(schools, police, fire protection, and emergency response services), trees, construction activities,
hazardous materials, visual quality, traffic congestion, the removal of Pruneridge Avenue, bike and
pedestrian access, air quality, and noise. In addition, several of the NOP comment letters address the
merits of the project itself and not the potential adverse environmental impacts that are the subject of
this EIR. The NOP and written comments are included in Appendix A of this EIR.
2. Significant Impacts
Under CEQA, a significant effect on the environment (significant impact) is defined as, "...a
substantial , or potentially substantial, adverse change in any of the physical conditions within the
area affected by the project, including land, air, water, minerals, flora, fauna, ambient noise, and
objects of historic or aesthetic significance."' Implementation of the proposed project has the
potential to result in adverse environmental impacts in several environmental areas. Impacts in the
following areas would be significant:
• policy
• land use
• biological resources
• cultural resources
• geology, soils, and seismicity
• hydrology and water quality
• hazards and hazardous materials
• transportation and circulation
• noise
• air quality
• public services and utilities
3. Significant Unavoidable Impacts
Implementation of the proposed project would result in significant unavoidable impacts in the
following topical areas. Significant unavoidable impacts are those that cannot be mitigated to a less -
than -significant level with feasible mitigation measures.

II. SUMMARY
• Would not fully implement some provisions of the Land Use/Community Design, Circula-
tion, and Environmental Resources/Sustainability Elements of the General Plan related to
bike and pedestrian access due to the proposed vacation of a segment of Pruneridge
Avenue, and lack of provision of a trail segment along Calabazas Creek, and these
inconsistencies would result in an environmental impact.
• Generate air pollutant emissions during the construction and operational periods that could
violate air quality standards at the project and cumulative levels.
• Under Existing plus Project conditions, Background plus Project conditions, and/or
Cumulative plus Project conditions, cause unacceptable conditions at five intersections, ten
mixed flow freeway segments, one High Occupancy Vehicle (HOV) segment of a freeway,
and cause excessive queuing on I-280 off ramps at Wolfe Road.
• Create new challenging conditions for pedestrians and interfere with pedestrian and
bicyclist accessibility to the site and surrounding areas due to proposed modifications to the
roadway network and high project -related traffic volumes.
• Impact residents of The Hamptons due to the closure of Pruneridge Avenue by reducing
transit access due to the reroute of Santa Clara Valley Transportation Authority (VTA)
Route 81, affecting access to areas east of North Tantau Avenue.
All other impacts of the proposed project would be mitigated to a less -than -significant level
with the incorporation of the mitigation measures identified in this EIR.
4. Alternatives to the Proposed Project
The four alternatives to the proposed project analyzed in Chapter VI of this EIR are summarized
below. These alternatives (with the exception of the CEQA-mandated No Project alternative) were
intended to feasibly attain most of the basic objectives of the project while avoiding or lessening any
of the significant effects of the project. The following four alternatives, representing a reasonable
range of alternatives, were developed based on input from the City of Cupertino Community
Development Department, project applicant, and the consultant team.
The No Project alternative assumes that the existing buildings on the site would be
maintained in approximately their current condition and would be fully occupied such that
the site would contain approximately 9,800 employees. Pruneridge Avenue would remain a
public road.
The Pruneridge Avenue alternative assumes that, similar to the proposed project, Apple
would develop a new campus on the site comprising 3,420,000 square feet of office,
research, and development uses; 245,000 square feet of auditorium, fitness center, and
Valet Parking Reception uses; 92,000 square feet of utility plants; and parking and ancillary
buildings (such as security receptions and landscape maintenance buildings). However,
Pruneridge Avenue would remain a public road, which would reduce the amount of open
space on the campus and require the implementation of separate security mechanisms on
the portions of the campus north and south of Pruneridge Avenue. The Pruneridge Avenue
alternative would also require the reconfiguration of buildings on the site, changes to the
size and shape of some buildings, modified access points and other changes to reflect a
divided campus. Changes to the project grading and excavation plan would also be

LSA ASSOCIATES, INC. APPLE CAMPUS 2 PROJECT EIR
JUNE 2015 II. SUMMARY
required, resulting in a greater volume of off -hauled materials compared to the proposed
project.
The Reduced Construction alternative assumes that the same amount of developed
square footage would be constructed on the project site but with a different campus
configuration and design that would resemble a traditional office complex with multiple
office buildings. The Reduced Construction alternative would require substantially less
excavation and grading activities during project construction, as well as a shortened
construction timeline. Under this alternative, a new campus would be developed consisting
of four- to five -story buildings, surface parking lots, two four- to six -level above -grade
parking garages, and a reduced open space area. Similar to the project, the segment of
Pruneridge Avenue within the site would be vacated for site security reasons. The project
site also would have multiple access points along North Wolfe Road, East Homestead
Road, and North Tantau Avenue.
The Reduced Density alternative assumes development of a smaller campus on the site
comprising approximately 2.2 million square feet of office, research, and development
space. This space, in addition to utility and ancillary space, would accommodate 8,000
Apple employees, for a total headcount lower than the No Project alternative. Similar to the
project, the segment of Pruneridge Avenue within the site would be vacated, allowing for
the development of a unified campus.
When the No Project alternative is the environmentally superior alternative, CEQA Guidelines
Section 15126.6(e)(2) requires the identification of an environmentally superior alternative other than
the No Project alternative. The No Project alternative is considered the environmentally superior
alternative (even though it would fail to achieve any of the project's objectives) because many of the
environmental impacts associated with implementation of the other alternatives would be avoided.
Therefore, a different alternative must be identified as environmentally superior. The Reduced
Density alternative would be environmentally superior to the Pruneridge Avenue alternative and
Reduced Construction alternative because it would avoid or reduce significant traffic, noise, and air
quality impacts due to lower levels of employment on-site compared to the project. The reduction in
operational traffic impacts is particularly important, since increased traffic affects most members of
the community and was one of the key concerns identified by the community during the EIR scoping
session.
C. SUMMARY TABLE
The information shown in Table II -1, Summary of Impacts and Mitigation Measures, has been

Providing a second right -turn lane would improve intersection
operations to LOS E with 63.0 seconds of delay. However, there are
right-of-way constraints that render a second right -turn lane
infeasible, since there would be less than 7 feet of right-of-way

The mitigation measure would require the construction of a new
retaining wall along I-280, since Calvert Road would need to be
curved to properly align with two receiving lanes at the on-ramp.
There is existing right-of-way to accommodate this mitigation
measure. However, the measure would require widening the existing
bridge that crosses the creek running parallel to the west side of
Lawrence Expressway. The widening would cause secondary impacts
to the creek. Potential secondary impacts to the creek associated with
widening the existing bridge as a traffic mitigation measure are
addressed in Section VD, Biological Resources.

Providing a westbound overlap phase could have secondary impacts,
since southbound vehicles wanting to travel northbound would have
to travel to the Stevens Creek Boulevard/Wolfe Road intersection to
access northbound Wolfe Road. Field observations were conducted to
determine the existing percentage of vehicles making U-turns at the
intersections. The field data was used to estimate the impact of
diverting U-turns from Vallco Parkway to Stevens Creek Boulevard.
The LOS results show that both the Wolfe Road/Vallco Parkway
(42.4 seconds and LOS D) and Stevens Creek Boulevard/Wolfe Road
intersections (49.9 seconds and LOS D) would operate acceptably
with the proposed southbound U-turn restrictions at the Wolfe

o A temporary sound wall shall be constructed along the
northern project property line to block the line -of -sight
from the single-family residential properties north of East
Homestead Road to project construction areas in the
northern portion of the project site. This sound wall shall
be set back from the property line as much as feasible to
still allow for project construction activities to occur.
• The project contractor shall designate a construction liaison
that shall be responsible for responding to any local com-
plaints about construction noise. The liaison shall determine
the cause of the noise complaints (e.g., starting too early, bad
muffler) and institute reasonable measures to correct the
problem. A telephone number for the liaison shall be conspic-
uously posted at the perimeter of the construction site and
provided to all adjacent property owners prior to commence-
ment of construction.
• The project contractor shall ensure that all construction
equipment has appropriate high-quality noise muffling and
abatement devices, which would be properly maintained and
used at all times such equipment is in operation.
• The project contractor shall, to the extent feasible, place all
stationary construction equipment so that emitted noise is
directed away from sensitive receptors nearest the project
site.

within 750 feet of any residentially zoned property only
between the hours of 7:00 a.m. and 8:00 p.m. on weekdays,
and between the hours of 9:00 a.m. and 6:00 p.m. on
weekends. No such work shall be permitted on holidays (i.e.,
New Year's Day, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, Christmas Day), except as approved
by the Community Development Director. A Noise Variance
may be obtained from the Noise Control Officer for each
occurrence of specific temporary construction activities.
• Construction activities, other than street construction, shall be
prohibited on holidays, unless they meet the City of
Cupertino's nighttime maximum permissible noise level
standards.

piles, graded areas, and unpaved access roads) shall be
watered two times per day.
• All haul trucks transporting soil, sand, or other loose material
off-site shall be covered.
• All visible mud or dirt tracked -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.
• All vehicle speeds on unpaved roads shall be limited to 15
miles per hour (mph).
• 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.
• Construction equipment idling times shall be minimized
either by shutting equipment off when not in use or reducing
the maximum idling time to 2 minutes (as required by the
California airborne toxics control measure Title 13, Section
2485 of California Code of Regulations [CCR]). Clear
signage shall be provided for construction workers at all
access points.
• All construction equipment shall be maintained and properly
tuned in accordance with the manufacturer's specifications.
All equipment shall be checked by a certified mechanic and
determined to be running in proper condition prior to
operation.

Cupertino regarding dust complaints. This person shall
respond to complaints and take corrective action within 48
hours. The BAAQMD's phone number shall also be visible to
ensure compliance with applicable regulations.
• 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 a moisture probe.
• All excavation, grading, and/or demolition activities shall be
suspended when average wind speeds exceed 20 mph.
• Vegetative ground cover (e.g., fast -germinating native grass
seed) or other plants that offer dust mitigation measures shall
be planted in disturbed areas as soon as possible and watered
appropriately until vegetation is established.
• The simultaneous occurrence of excavation, grading, and
ground -disturbing construction activities on the same area at
any one time shall be limited. To the extent feasible, activities
shall be phased to reduce the amount of disturbed surfaces at
any one time.
• All trucks and equipment, including their tires, shall be
washed off prior to leaving the site.
• Sandbags or other erosion control measures shall be installed
to prevent silt runoff to public roadways from sites with a
slope greater than 1 percent.
• Use low volatile organic compound (i.e., ROG) coatings
beyond the local requirements (i.e., Regulation 8, Rule 3:
Architectural Coatings).
• To the maximum extent feasible, all construction equipment,
