The project will be sufficiently parked. and will not negative affect the parking TLJP-2012-01, TR-2012-12 Mock Building and Associated Tree Removals Page 2 demand of the entire site since the existing office building is anticipated to stay vacant throughout the lifespan of the proposed temporary mock up building. The temporary mock up building will be visible from the parking lots of the adjacent properties, which currently are all owned by Apple. The project will have limited visibility from certain vantage points along Prunridge Avenue. Screening trees have been selected from the list of trees being removed which shall be transplanted to allow additional screening. The project is proposing an eight foot construction fence around the property, which will additionally help screen the proposed building from the public right of way. Large construction apparatus and temporary building scaffolding shall be placed or erected to facilitate the construction of the building during the initial six month of construction. The mock up building is approximately 46 feet 6 inches in height and consists of a 9,200 s.f first floor and a 9,000 s.f. second floor. The building will be primarily used for the display and testing of various architectural products, building material samples and mechanical systems. The building also has the ability to house up to 30 employees as a temporary office. Trees: The project proposes the removal of 66 trees in order to facilitate the construction of the mock up building. None of these trees are considered Specimen Trees as defined by the City's Protected Tree Ordinance. In response to the recommendations from the City's Consulting Arborist, the applicant will be required to relocate one Olive Tree (#4801) in a landscape area adjacent to the mock up building. Another Olive Tree (#4789) will also be relocated to an existing landscape berm along Pruneridge Avenue. As a condition of this approval, the relocation of these trees is considered temporary and their final location will be determined when the new campus landscaping plan is finalized. The applicant shall be required to plant replacement trees as required by the City's Protected Tree Ordinance. Environmental Determination: The project has been deemed to be Statutorily Exempt pursuant to Section 15268 of the CEQA Guidelines (Ministerial Projects) and Categorically Exempt under Sections 15311, 15332 and 15304. Since the project site is subject to the preparation of an Environmental Impact Report, the project has been reviewed by the Environmental Consultant, LSA Associates to identify conditions of approval that this temporary project would be subject to as well. The Director of Community Development approves the temporary use permit and tree removal permit with the following conditions of approval: TUP-2012-01, TR-2012-12 Mock Building and Associated Tree Removals Page 3 1.

The proposed Ridgeview Court Two Annex[RC2A] is a two-story 18,600 sqft temporary office annex adjacent to an existing office building known as Ridgeview Court 2 [RC2], located at 10501 North Tantau Avenue, between Pruneridge Avenue and the I-280. The objective of the proposed project is to create a fully functional workplace environment for testing, viewing, and using a variety of different construction materials, finishes, architectural samples, and other building and furniture systems.Although it has not been confirm�d, there is a possibility that one of the levels of the building may be used as temporary office space for approximately 30 people, and this should be considered in the review of the proposed project. Site Development and Utilities The proposed footprint would replace approximately 9,300 sqft of existing surface parking adjacent to the west entrance of Ridgeview Court Two, which is currently unoccupied, but was previously used as office space. The zoning for this Parcel is P(MP). No significant re-grading beyond the requirements for access and water drainage will be employed for this project.A small utility skid will be located to the northeast of the annex building (within the construction zone)which will house heat pumps, fire water pump and electrical panels to support the temporary building for its lifespan.All of this wifl be removed when the temporary building is removed. Construction Management The construction period is expected to last approximately six months. During construction, there will be a an eight foot high security perimeter erected around the construction zone. In addition, a temporary covered construction scaffolding will be erected around the building itself. This will allow finish materials to acclimate in a conditioned environment prior to the building being made water-tight, and will reduce the overall construction time. Both fence and scaffolding are temporary and will be removed upon completion of the project's construction period (ie 6 months). The security perimeter will remain in place until such time as the Apple Campus 2 security perimeter is put in place (anticipated to be January 2013), at which time the RC2A perimeter would be removed. Two security huts located at the north and south entries to the security perimeter will also be installed for the duration of the construction, to control access in and out of the construction area. Additionally, there will be temporary toilet facilities provided to the east of RC2A, screened from view by RC2. The toilet facilities would be kept in place for the duration of RC2A, after construction is completed. There is ample space for the storage of materials, equipment and cranes within the security perimeter, and therefore there will be no construction equipment stored or parked outside of the designated area. RC2A is scheduled for substantial completion in Fall of 2012, and would be operational until approximately the fall of 2015, when it would be removed from the site, along with any remaining associated outbuildings (ie toilets and utility skid). Site Access and Parking Primary site access for both construction and eventually the occupant's vehicles will be from Tantau Avenue, with a secondary temporary access from Pruneridge Avenue for construction vehicles during construction.An 20ft wide emergency fire lane will be kept clear through the site, providing fire appliance access to both the RC2A and RC2. For more information, reference P-RC2A-06. Foster + Partners During construction, 89 temporary construction parking will be provided in adjacent lots to the west, which previously served unoccupied building RC4. There are 199 spaces within the construction perimeter, which will not be used during construction.After construction is complete, approximately half(100) of these spaces will be made available again to serve any future occupants of RC2A. It is expected there could be approximately thirty people occupying RC2A. Trees and Landscape As part of planning approval, an application for a tree removal permit has been submitted. There are sixty-six trees within the construction perimeter that are being tagged for removal, all of which would eventually be removed as part of the Apple Campus 2 project. Two existing olive trees (4801 and 4789) which have been identified as of good quality and in fair condition, are being relocated, one to the north at Pruneridge Avenue(4789) and one to be used as part of a landscape mock-up adjacent to RC2A (4801). There are also four Italian Cypress trees (4775, 4776, 4778 and 4782)that will be relocated to screen the RC2A construction zone during construction but will ultimately be removed. Please reference planning sheet P-RC2A-01 for a tree list and condition and P-RC2A-04 for further information, as well as email from Dave Muffly, Apple's arborist, who will be supervising the relocation of the trees and monitor their condition. Both olive trees will eventually be replanted as part of the Apple Campus 2 landscape. Approximately 7,000 sq ft adjacent to the south fa�ade has been allocated for new soft surfacing and landscaping. Architectural Description The temporary annex building will consist of two levels with a mechanical plant room on the roof, and a glazed penthouse which provides natural light to the interior spaces, and air extract as part of the natural ventilation system. The glazed penthouse has a finished height of 47'-6"above grade. Level 01 will be 9,300 sq ft of unoccupied open plan space used primarily for the display of architectural products and material samples. Level 02 is approximately 9,000 sq ft of office space which may be temporarily occupied by approximately 30 people. External facade finishes consist of a painted metal cladding to the north, east and west elevations, while the south elevation is fully glazed, and has a cantilevered opaque glass overhang to shade the glass facade. The roof is made primarily of photovoltaic solar panels and glazed skylight panels. RIVERSIDE L � � LSA ASSOCIATES. INC.

INTRODUCTION This memorandum provides a description of the proposed Ridgeview Court 2 (RC2)Annex(project) and evaluates whether the project would be statutorily exempt from detailed analysis under tlie California Environmental Quality Act(CEQA). The project would involve the construction of a temporary building on land owned by Apple,which would be used to house testing facilities for new technologies and building materials. The RC2A Annex would be developed independently of the Apple Campus 2 Project,which is the subject of detailed environmental review.As described in more detail in this memorandum,the project would be eligible for a Statutory Exemption pursuant to Section 15268 of the CEQA Guidelines (Ministerial Projects)because it would not be subject to a discretionary permit and would not be expected to result in significant environmental impacts.' B. PROJECT DESCRIPTION The following describes the project location, existing conditions on the project site, and physical and operational components of the project. The description is based on project information prepared by Apple and the project architect, Foster+Partners.2 1. Regional Location and Setting The approximately 2.9-acre project site is located entirely within Apple's approximately 56-acre Ridgeview Campus in the City of Cupertino. Figure 1 shows the location of the project. The project site is bordered by surface parking and an office building(RC3)to the north; an office building(RC2) to the east; surface parking and Calabazas Creek to the south;and surface parking and an office building(RC4)to the west. Building RC3 is approximately 50 percent occupied; Buildings RC2 and RC4 are unoccupied. The address of the site is 10501 North Tantau Avenue. The project site is accessible from Pruneridge Avenue to the north and North Tantau Avenue to the east. �As discussed at the end of this memorandum,the project would also be eligible for a Categorical Exclusion under Section 15311 (Accessory Structures)and Section 15332(In-Fill Development Projects)of the CEQA Guidelines. 2 Foster+Partners,2012.Project Data and Ridgeview Court Two Annex Project Narrative.February 23.

Regional Vicinity and Project Location Map 1:ACOC1201 A�mex Buildings\figures\Fig_l.ai (4/]0/12) LSA ASSOCIATES, INC. Figure 2 is an aerial photograph of the project site and its surrounding. As shown in that figure,the project site is located in the northwest portion of a 5.45-acre irregularly-shaped parcel,known as Parcel B. Parcel B comprises the unoccupied Building RC2 and associated parking and landscaping. The site is located approximately 125 feet to the north of Calabazas Creek. 2. Existing Conditions The project site consists of a surface parking lot located to the west of Building RC2. The surface parking lot contains approximately 199 parking spaces. There are a total of 157 trees within the project site that consist of the following species, ali of which are not native to the area:American Sweet Gum (Liquidambar styraciflua), Raywood Ash(Fraxinus o. 'Raywood'), Oleander(Nerium oleander), Silver-Dollar Gum (Eucalyptus polyanthemos),Flowering Plum(Prunus cerasifera), Tulip Tree(Liriodendron tulipifera), Italian Cypress (Cupressus sempervirens), and Olive Tree(Olea europaea).Native but non-local species within the project site include the Coast Redwood(Sequoia sempervirens). The project site is designated Industrial/Residential in the City of Cupertino General Plan, which "[a]llows primarily industrial uses and secondarily residential uses or a compatible combination of the two."The site is zoned Planned Development(Planned Industrial)(P(MP)), which allows for the planned development of professional, executive and administrative offices; medical and allied labora- tories; research and development uses; light manufacturing; processing; and assembling and storage of projects and materials. Figure 3 shows the existing and proposed configuration of buildings on the site. 3. Proposed Project The proposed project would involve the construction of a three-level, 18,200-square-foot temporary building and associated access, parking, and utility infrastructure. Figure 3 shows the proposed site plan. Desi�n. The annex building, which would have a footprint of approximately 9,300 square feet,would extend to a maximum height of 47.5 feet. The northern edge of the building would be aligned with the northern edge of Building RC2 in order to reduce the impact of the new building on views from North Tantau Avenue. The first floor of the building would contain approximately 9,200 square feet of interior space that would be used primarily for the display of architectural products and material samples. The second floor of the building would contain 9,000 square feet of office space that may be occupied by up to approximately 30 employees. The third floor would consist of a mechanical plant and glazed penthouse, which is intended to provide natural light to the interior spaces and aid in ventilation. Photovoltaic panels and skylights would cover the roof of the structure. The north, east, and west sides of tlle structure would be faced with metal cladding. The south eleva- tion would be almost completely glazed.A cantilevered glass overhang would assist in shading the glass farade and reducing energy consumption. Access and Parkin�. Primary access to the RC2 Annex would be via North Tantau Avenue(with secondary truck access via Pruneridge Avenue). In addition, a 20-foot-wide emergency access lane would extend through the site, adjacent to the western side of the annex building. Gates at the entries/ exits of the emergency access lane would restrict access to the site.An 8-foot-tall perimeter fence 3 LSA ASSOCIATES, INC. would be established around the annex building(with openings for pedestrians). This fence would be covered in fabric.After construction of the project, approximately 100 parking spaces would be provided on the site for employees. Lighting would be installed near parking areas and pathways. Utilities. The proposed project would include heat pumps,fire water pumps,electric panels, and associated equipment on a concrete pad surrounded by a chain link fence immediately northeast of the proposed building. Stormwater treatment facilities would be integrated within landscaped areas to the south of the proposed building and would connect to an existing storm drain line. Electrical and telecommunication lines would connect to existing lines. Use. As described by Foster+Partners,the RC2 Annex would be used"for testing,viewing, and using a variety of different construction materials, finishes, architectural samples, and other building and furniture systems."The RC2 Annex would be used for a total duration of 3 years(from Fall 2012 through Fall 2015).After this 3-year period,the structure and all accessory structures would be removed from the site. However, in the unlikely event that the temporary use permit is not renewed after its initial approval,the structures would need to be dismantled and removed from the site. Other Features. An approximately 7,000-square-foot area adjacent to the southern side of the annex would be developed into a landscaped area. Construction. Construction of the project would extend over approximately 6 months and would require removal of approximately 100 parking spaces from the project site. In addition, 66 trees within the project site would be removed. Of these trees, one olive tree would be relocated on the site and another olive tree would be relocated north to Pruneridge Avenue. Both olive trees, which are in good condition, are planned for further relocation with implementation of the Apple Campus 2 Project. Four cypress trees would be temporarily relocated to screen the annex and for temporarily landscaping,but would ultimately be removed when the annex is dismantled. The trees that would remain on the site would ultimately be removed with implementation of the Apple Campus 2 Project (if that project is approved). Grading on the site would be minimal, and would be restricted to trenching for utilities, access routes, and drainage. During the construction period, an approximately 8-foot-tall fence would be installed along the perimeter of the project site. In addition, construction scaffolding covered in a light-colored opaque fabric would be erected around the building in order to reduce potential water damage from precipitation and to allow building materials to acclimate. The scaffolding would be removed after the approximately 6-month construction period,but the perimeter fence would remain until a new security fence is installed as part of the Apple Campus 2 Project(if that project is approved). Two security huts(one each at the north and south sides of the security perimeter)would be developed to control access into the construction zone. Temporary bathrooms would be installed to the east of the proposed RC2 Annex. In addition, all construction equipment would be stored within the security perimeter for the duration of the construction period. Parking for construction employees would comprise 89 spaces to the west of the site. Construction activities would generally be restricted to the hours of 7:00 a.m.to 8:00 p.m. on weekdays and 9:00 a.m.to 6:00 p.m. on weekends,per Section 18.48.053 of the City of Cupertino 4 � . . , .o ., � � 'T w . _ .r, ..

This chapter allows for admin- istrative approval of a conditional use permit,authorizing the use of a site in any zoning district for a temporary use if the use would: 1)not be detrimental or injurious to property or improvements in the vicinity;2)not be detrimental to the public,health, safety, general welfare, or convenience; and 3) would be located and conducted in a manner in accord with the Cupertino General Plan and the purposes of the Municipal Code.3 The Director of Community Development must report her decision to the City Council and Planning Commission in time to allow an appeal of the decision within 14 calendar days. Support for the Director's Approval is contained in this memorandum and the staff report prepared for the project. A Director's Approval is considered a ministerial action because a conditional use permit for a temporary use is issued if certain conditions are met. Because no discretion is involved in the issuance of this permit,the permit is issued by City staff(and not a legislative body). C. ENVIRONMENTAL IMPACT ANALYSIS This section provides an environmental impact analysis of the proposed project and has been included in this Statutory Exemption to provide evidence that the proposed project would result in no significant impacts and would not require mitigation measures to reduce impacts to a less-than-significant level. The City's Conditions of Approval (COAs)outlined in this memorandum would be implemented to ensure that the proposed project would not result in significant environmental impacts. The following topics have not been included in the discussion as it has been concluded that these do not apply to the project or project site: Agricultural Resources, Forestry Resources, and Mineral Resources. The site is urbanized and is not suitable for farming, forestry, or mineral extraction. 1. Planning Policy a. General Plan.The project is designated as Industrial/Residential on the City's General Plan Land Use Map and the intended function of the RC2 Annex(testing,viewing, and using building materials)would be consistent with this designation. The project would not permanently change the use of land on the site because the temporary structure would be dismantled after 3 years. b. Zoning Ordinance. The project site is located in the Planned Development(Planned Indus- trial)(P(MP))zone on the City's Zoning Map. The P designation is followed by a secondary designa- tion which indicates the types of land uses that are generally permitted within that designation. The permitted and conditionally permitted land uses are those associated with the secondary designation. The P(MP)zone allows for the planned development of professional, executive and administrative offices; medical and allied laboratories;research and development uses; light manufacturing; process- ing;and assembling and storage of projects and materials. The proposed uses(assembling and storage of projects and materials in order to develop offices and laboratories)would be consistent with the City's Zoning Ordinance. 3 Cupertino,City of,2011.Municipal Code,Chapter 19160, Temporary Uses. � LSA ASSOCIATES, INC. Under the P(MP)designation,ma�cimum building coverage is 40 percent,and maximum building height is 40 feet(although taller buildings are permitted if so designated in the development plan and allowed by the General Plan). The proposed building footprint(approximately 0.21 acre)would com- prise less than 40 percent of the 2.9-acre project site.Although the height of the building would exceed the 40-foot threshold,a deviation from this threshold would be permitted as part of the Director's Approval and(as discussed below in Aesthetics),the building height would not block scenic views, adversely affect the visual character of the area, or otherwise result in significant environmental effects. c. Guidelines and Standards for Land Use Near Streams. The Guidelines and Standards for Land Use Near Streams(Guidelines)4 are designed to provide guidance on development projects located near streams in Santa Clara County, and to assist local agencies in permitting such develop- ment and designing mitigation, as warranted. The City of Cupertino uses the Guidelines in its review of applications for development near streams, in accordance with General Plan and Zoning Ordinance policies and regulations intended to protect water quality. The site plans for the proposed project indicate that the proposed RC2 Annex would be located approximately 360 feet away from Calabazas Creek. In addition,the nearest site boundary would be located approximately 125 feet away from the creek. As a result,the proposed project would comply with the basic setback requirement outlined in the Guidelines(which requires structures to be set back at least 50 feet from tlie top of the creek bank). The proposed project would not be established within the Calabazas Creek riparian zone and would not directly affect the creek or its banks. Stormwater would be managed on the site per standard City requirements and COA HYD-1, and would not indirectly affect the ecological health of the creek or its riparian corridor. 2. Land Use The City of Cupertino is a suburban community characterized by predominantly single-family resi- dential subdivisions with distinct commercial and employment centers. The proposed project would be located within a corporate campus,which is characterized by individual low-rise buildings surrounded by surface parking lots and landscaping. Ridgeview Court,which is considered part of Apple's Ridge- view Campus, contains nine buildings comprising approximately 1 million square feet of office space (and is generally bounded by Pruneridge Avenue on the north;North Tantau Avenue on the east; I-280 on the south; and The Hamptons apartment community on the west). These buildings are spaced throughout the site; each is surrounded by surface parking lots. In general, landscaped areas are small in size and are clustered around buildings. Ridgeview Court is also part of the North Vallco area of the Vallco Industrial Park. The Vallco Industrial Park is a major commercial and employment center in the City. Land uses in the industrial park north of Interstate 280 (I-280)are primarily office and research and development. Because the project would be located on a corporate campus and would be generally consistent with its General Plan and Zoning Ordinance designations, implementation of the project would not conflict with any applicable land use plan,policy, or regulation. In addition, development of the temporary building would not obstruct access between North Tantau Avenue and North Wolfe Road(or other streets in the vicinity of the site)and so would not divide disrupt or divide an established community. The temporary uses would be compatible with the primarily office uses surrounding the site and the 4 Santa Clara Valley Water Resources Protection Collaborative,2006.Guidelines and Standards for Land Use Near Sir•eams. July. g LSA ASSOCIATES, INC. proposed construction fencing and security buffer would minimize adverse effects on surrounding land uses during the construction and operational periods. The project site is not located within a habitat conservation plan or natural community conservation plan and would not conflict with any such plan. 3. Aesthetics The project site is located within a corporate campus in an urban area,adjacent to two-story office buildings and surface parking lots. The project site is generally flat and consists of a surface parking lot with associated landscaping. Visual conditions within and in the immediate vicinity of the site are urban in nature and are characterized by land uses typical of suburban office parks. The architecture of existing Building RC2 and nearby buildings is characterized by box-shaped masses with minimal architectural detail, large windows, and flat rooflines. The General Plan designation for the site permits buildings extending up to 60 feet in height. The proposed temporary structure,which would be characterized by rectilinear massing,metal clad- ding, and extensive glazing on the southern side, would be visually compatible with surrounding buildings and would not compromise the visual integrity of the site. In addition,the proposed building height(47.5 feet)would be below the maximum building height permitted in the General Plan for the site. The visual quality of the site would change during the 6-month construction period as personnel and equipment are active on the site and existing vegetation is removed. Temporary adverse effects to the visual environment would be less than significant with development of the 8- foot perimeter fence,use of scaffolding covered in light-colored opaque fabric, and relocation of four cypress trees to screen construction. Scenic views are limited in the vicinity of the site due to existing landscaping and corporate campus structures. Existing Building RC2 would block views of the RC2 Annex from North Tantau Avenue. In addition,views of the new structure from I-280 would be substantially limited due to intervening buildings and vegetation. The new structure would be highly visible from Pruneridge Avenue, but in the context of the relatively low existing visual quality of the existing parking lot(and the lack of scenic views from most south-facing viewpoints along Pruneridge Avenue), associated impacts would be less than significant. In addition,COA AES-1,which would require final City approval of a project landscaping plan,would further reduce the already less-than-significant impacts of the project on the visual character of the area and available views. Lighting is expected to be limited to nighttime security lighting and COA AES-2 would ensure that any outdoor night lighting on the project site would comply with the City's commercial lighting standards so as not to increase light levels off-site, increase glare,or substantially diminish nighttime views. 4. Population,Employment and Housing No housing would be constructed or removed as part of the proposed project,and therefore no associ- ated impacts would occur to the demographic composition of the area. The project would generate temporary construction-related employment(and potentially increase employment during the opera- tional period as new technologies and building materials are tested). However,this increase in employ- ment would be small in the context of overall expected employment growth in the region and would not result in adverse secondary effects(such as a substantial increase in demand for housing). 9 LSA ASSOCIATES. INC. , 5. Biological Resources As described in more detail below,the proposed project would not adversely affect any special-status species; riparian habitats; federally protected wetlands; or migratory corridors or nursery sites.The project also would not conflict with any policies,ordinances,or plans protecting biological resources. a. Special-Status Species. Tlie site is characterized by landscaping trees and other biological resources that are typical of suburban corporate campus environments. Due to the lack of high quality suitable habitat and prior disturbance at the project site, no special-status plant or animal species are expected to occur on the site. Therefore,the proposed project would not adversely affect any threat- ened or endangered species. b. Migratory Birds. Because the project site is located in a developed, urbanized area, most wild- life species in the vicinity are adapted to human-modified environments. Species that inhabit indus- trial and commercial areas are able to use ornamental landscaping as foraging habitat and/or escape cover, and some are able to exploit building crevices, rooftops, and/or ledges on buildings for nesting and/or roosting. Grading and construction activities near nests during the nesting season(February 1 to August 31) could cause nest abandonment and/or loss of eggs or young during the breeding season. However, implementation of COA BIO-1, which requires pre-construction surveys to be conducted by a quali- fied biologist and outlines protective measures, would ensure that adverse effects to nesting birds would be less than significant. c. City Ordinances and Policies Protecting Biological Resources.Chapter 14.18 of the City of Cupertino Municipal Code(Protected Tree Ordinance)includes regulations for the protection, preser- vation,and maintenance of trees of certain species and sizes.5 Removal of a protected tree requires a permit from the City. Protected trees include heritage trees in all zoning districts;any tree required to be planted or retained as part of an approved development application, building permit,tree removal permit, or code enforcement action in all zoning districts; and approved privacy protection planting in R-1 zoning districts.A formal tree survey was conducted on the project site to identify potential impacts to protected trees. Currently,there are l 57 trees on the project site,all of which are considered protected trees(as they were planted as part of an approved development application for the site). As part of the project,66 trees within the project site would be removed. Of these trees,two trees(olives)would be permanently relocated on the site. Four cypress trees would be temporarily relocated to screen the RC2 Annex and for temporary landscaping,but would ultimately be removed when the annex is dismantled. Although all trees have intrinsic value to the environment,the fast-growing, short-lived ornamental trees that occur within the project site clo not contribute significantly to the biological resource value of the area. The proposed project would be subject to a tree removal permit. Potential construction- period impacts would be reduced to a less-than-significant level with implementation of COA BIO-1. 5 Cupertino,City of.Chapter 14.18:Protected Trees.Ordinance No.07-2003.Website:www.cupertino.or�/ index.aspx?pa�e=506. 10 LSA ASSOCIATES, INC. The proposed project would not conflict with any known habitat conservation or coinmunity conser- vation plans. d. Jurisdictional Waters. The proposed RC2 Annex would be located approximately 360 feet away from Calabazas Creek,and well outside of the creek riparian zone. Portions of Calabazas Creek below the Ordinary High Water Mark would fall under U. S. Army Corps of Engineers and Regional Water Quality Control Board jurisdiction pursuant to Sections 401 and 404 of the federal Clean Water Act and the Porter-Cologne Water Quality Control Act. Because the proposed project would not include modifications to the bed, bank,or riparian corridor along Calabazas Creek,no impact to existing jurisdictional waters would occur. 6. Cultural Resources The project site is located in an urban area and soils in the project area were previously disturbed during the original construction of the office buildings in the area during the mid 1970s to late 1980s. No recorded archaeological or paleontological resources have been identified within the project site. In addition,Native American remains have not been identified within the project site. Grading and excavation activities related to project construction would occur but would be limited in extent as no major sub-grade facilities are proposed(and the flat site is currently suitable for development). Although project site soils have been previously disturbed,there is a remote likelihood that the project site may still contain subsurface archaeological deposits and paleontological resources, and ground-disturbing activities have the potential to affect these resources. If previously unidentified archaeological deposits,paleontological resources,and/or human remains are encountered during the project construction period, implementation of COAs CULT-1, CULT-2, and CULT-3 as part of the proposed project would protect these resources. Therefore,the proposed project would not cause a substantial adverse change in the significance of cultural resources. 7. Geology,Seismicity and Soils Preliminary geotechnical studies were conducted for the project area. The project area's geologic conditions are based on a site inspection,published and unpublished geologic reports and maps, and a preliminary site-specific geotechnical report.b As described in more detail below, it is unlikely that the proposed project would result in geology, soils, or seismicity impacts related to fault rupture, slope stabiliTy, subsidence, or erosion. a. Active or Potentially Active Earthquake(A-PEFZ)Fault.The project site is located in an urbanized area and is located in the seismically active San Francisco Bay Area. The most recent A- PEFZ maps indicate that the nearest active fault to the project site is the San Andreas Fault peninsula segment, located approximately 6 miles to the southwest.'Based on U.S. Geological Survey fault 6 Arup North America Ltd.,2011.Fosters+Partners,Cupertino Campus.Preliminary Geotechnical/nterpretive Report.

INC. maps,no potentially active faults underlie the project area.g Therefore,the proposed project would not be expected to be affected by rupture at the site of a known active or potentially active fault. b. Groundshaking. All structures in the Bay Area—including the proposed temporary structure— could be affected by ground shaking in the event of an earthquake. Violent ground shaking is expected in the project area during predicted earthquakes on the San Andreas and other active regional faults. This level of seismic shaking could cause extensive non-structural damage in buildings and limited structural damage. However, implementation of COA GEO-1,which requires a design-level geo- technical report(and implementation of recommendations identified in the report),would reduce the potential hazards associated with seismic activity to a less-than-significant level. c. Liquefaction. Liquefaction is the temporary transformation of loose, saturated granular sedi- ments from a solid state to a liquefied state as a result of seismic ground shaking. In the process,the soil undergoes transient loss of strength,which commonly causes ground displacement or ground failure to occur. The project area has been mapped in confonnance with the Seismic Hazards Map- ping Act and a Seismic Hazard Zone for liquefaction has been identified for the area immediately adjacent to Calabazas Creek,near the project site, indicating a liquefaction investigation is required in this area by the State.9 Santa Clara County has also mapped the vicinity of Calabazas Creek on the project site as a Liquefaction Hazard Zone.10 The required liquefaction assessment would be com- pleted as part of the design-level geotechnical report required by COA GEO-1, and the City would review and approve the geotechnical report prior to issuing grading or building permits. Therefore, the proposed project would result in less-than-significant impacts related to liquefaction. d. Slope Stability. The project site is in an area mapped by the City of Cupertino as stable with regard to landslides," and there are no Seismic Hazard Zones for landslides on the project site. There- fore, a geotechnical investigation addressing potential landslide hazards would not be required.1z e. Settlement Settlement may occur when loads, such as structures or fill, are placed on compressi- ble subsurface materials(including imported fill)or if improvements straddle the boundary between different types of subsurface materials(e.g.,a boundary between native soil and fill). The project area has been developed and it is expected that some settlement has occurred in the past due to existing and historical structural loads. However, portions of the project area that contain loose or uncontrolled (non-engineered)fill may be susceptible to differential settlement. Implementation of COA GEO-1 would reduce the potential hazards associated with settlement or differential settlement to a less-than- significant level. g U.S.Geological Survey,2011.Earthquake Hazard Program Quaternary Faults.Website:geohazards.usgs.gov/ Qfaults/man.ahv(accessed November 10,2011). 9 California Geological Survey,2002.California Department of Conservation.State of California Seisrnic Hazard Zones, Cupertino Quadrangle, Official Map.

Soils within the project area may also have a moderate to high shrink-swell potential. Damage to structures or property could result from expansive or corrosive soils. Moderate to high shrink-swell potential soils are classified as expansive soils and construction would require appropriate engineer- ing.13 Soil testing for corrosion potential has not yet been performed and the proposed building may require corrosion protection.14 The preliminary geotechnical report indicated soil was preliminarily assumed to be granular,with minimal fine-grained soils that could have expansive or corrosive properties. Implementation of COA GEO-2 would reduce the impact from potentially expansive or corrosive soils to a less-than-significant leve1.15 f. Subsidence. The proposed project would not be expected to contribute to regional subsidence since groundwater extraction for water supply is not proposed. g. Erosion. Long-term erosion hazards are also not expected since most of the site is currently paved, and the project site would remain paved or covered by structures, landscaping, and impervious surfaces. All of the recommendations outlined in the design-level geotechnical report(required as part of COAs GEO-1 and GEO-2)would be incorporated into the project's construction documents. Compli- ance with the recommendations of the geotechnical investigation prepared for the project would ensure that potential impacts associated with geology, soils,and seismicity would be less than signifi- cant. 8. Hydrology and Water Quality The project site currently contains a parking lot with associated landscaping. Stormwater runoff from the site discharges into drain inlets that convey the runoff via the City storm drainage system into Calabazas Creek,and ultimately into San Francisco Bay. Almost all of the project site is covered by impervious surfaces. a. Municipal Stormwater Management Requirements. Pursuant to Section 402 of the Clean Water Act(CWA)and the Porter-Cologne Water Quality Control Act, municipal stormwater dis- charges in the City of Cupertino and other member agencies of the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCWRPPP)are regulated under the San Francisco Bay Region Municipal Regional Stormwater National Pollutant Discharge Elimination System(NPDES) Permit, Order No. R2-2009-0074,NPDES Permit No. CAS612008, adopted October 14,2009(MRP). MRP Provision C.3 addresses post-construction stormwater management requirements for new devel- opment and redevelopment projects that add and/or replace 10,000 square feet or more of impervious area. Provision C.3 requires the City to require incorporation of site design, source control,and storm- water treatment measures into development projects,to minimize the discharge of pollutants in stormwater runoff and non-stormwater discharge, and to prevent increases in runoff flows. The MRP 13 Natural Resources Conservation Service,2010.Department of Agriculture. Web Soil Survey. Website: websoilsurvev.nres.usda.�ov/ano/HomePaee.htm(accessed September 16,2011). �4 Arup North America Ltd.,201 l,op.cit. 15 Arup North America Ltd.,2011,op.cit. 13 LSA ASSOCIATES, INC. requires that Low Impact Development(LID)16 methods be the primary mechanism for implementing such controls. MRP Provision C.3 would apply to the proposed project even though it would involve the development of a temporary structure because the project would involve changes to over 10,000 square feet of impervious surfaces. An approximately 7,000-square-foot landscape area(which would absorb stormwater)would be located to the south of the proposed building. In addition, stormwater treatment facilities would be integrated into the site design and would connect to an existing storm drain line. The project sponsor would also be required to submit a Storm Water Management Plan(per COA HYD-1)with building plans,to be reviewed and approved by the City of Cupertino Public Works Department, Environ- mental Programs Division. Therefore,the proposed project would not violate water quality standards during its temporary operation. At a minimum,the Storm Water Management Plan is required to include the elements listed in COA HYD-1. b. Vio(ate Water Quality Standards During Construction. There may be a potential for stormwater runoff generated during construction of the proposed building to contain contaminants that could affect Calabazas Creek and downstream water bodies and violate water quality standards. However,existing regulatory programs would reduce any potential impacts to a less-than-significant level. Consistent with the requirements of the Statewide Construction General Permit(and COA HYD-1),the project applicant would be required to prepare and implement a Stormwater Pollution Prevention Plan(SWPPP)designed to reduce potential adverse impacts to surface water quality through the project construction period.The proposed project would also be subject to the City Storm Water Pollution Prevention and Watercourse Protection Ordinance(Chapter 9.18), which prohibits discharge of any waste to a storm drain and requires immediate notification of the Director of Public Works in the event of any accidental discharge. Therefore,the project would not be expected to substantially adversely affect water quality. c. Flooding.In accordance with established City requirements,the proposed project would be required to upgrade any affected or adjacent drainage infrastructure and stormwater conveyances as necessary to accommodate a 10-year storm event. Therefore,the project would not be expected to result in downstream flooding. d. Groundwater. The proposed project would not use groundwater for water supply and therefore no impacts to groundwater supplies would occur. e. Alter the Course of a Stream or River.The nearest edge of the project site is located approximately 125 feet away from Calabazas Creek. Therefore,the project would not change the course of a stream or river, or otherwise cause changes in the drainage pattern of the creek. f. 100-Year Flood Zone and Flood Risks. The project site is located in Zone X, Other Flood Areas. Zone X comprises areas of 0.2 percent annual chance of flood;areas of 1 percent annual chance of flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 1 percent annual chance flood."The project site is not within a 16 The goal of LID is to reduce runoff and mimic a site's predevelopment hydrology by minimizing disturbed areas and impervious cover and then infiltrating,storing,detaining,evapotranspiring(i.e.,evaporating water from soil and plants), and/or biotreating stormwater runoff close to its source. 14 LSA ASSOCIATES, INC. dam failure inundation area and therefore,would not expose people or structures to a significant risk of loss, injury, or death involving flooding. In addition,the distance of the project site from San Francisco Bay and the elevations of the site above mean sea level would preclude risks from sea level rise, seiches,and tsunamis, or extreme high tides. 9. Hazards and Hazardous Materials a. Hazardous Materials. Hazardous materials(e.g.,fuels, lubricants, paints, adhesives)would be transported and used on-site for construction activities. It is likely that the construction contractor would store these hazardous materials and vehicles on-site for the duration of construction activities (all storage would occur within the perimeter security fence). Accidental releases of hazardous materials could affect soil and/or groundwater quality,or could result in adverse health effects to construction workers,the public, and the environment. However, implementation of COAs HAZ-la and HAZ-lb,which address proper storage areas and emergency preparedness and response proce- dures,would reduce this potential impact to a less-than-significant level. Compliance with these COAs would occur in conjunction with implementation of the Storm Water Pollution Prevention Plan and Best Management Practices required for the proposed project(see COA HYD-1). In addition,the Santa Clara County Fire Department and City of Cupertino Building Division coordi- nate the review of building permits to ensure that hazardous materials requirements are met prior to construction, including required separation between hazardous materials and sensitive land uses, and proper hazardous materials storage facilities.Any businesses that transport, generate, use, and/or dispose of hazardous materials within the project site would also be subject to existing hazardous materials regulations, such as those implemented by the Santa Clara County Department of Environ- mental Health Hazardous Materials Compliance Division and hazardous materials permits from the City of Cupertino. The City of Cupertino also conducts inspections for fire safety and hazardous materials management of businesses, in accordance with the City of Cupertino Hazardous Materials Storage Ordinance. The risks associated with release of hazardous materials into t11e environment from the routine transport, use, storage, or disposal of hazardous materials following construction are therefore considered a less-than-significant impact. b. Hazard Materials Site. Building RC2, located at 10501 North Tantau Avenue, was not listed on agency environmental databases as posing a hazardous materials-related health risk. A Phase I and Phase II Investigation for the project area was conducted in 2006. The site was used for offices, administrative activities, and research and development. Sub-slab soil vapor samples were reported with tetrachloroethene(PCE)and trichloroethylene(TCE)at maximum concentrations below the Regional Water Quality Control Board San Francisco Bay Region(RWQCB)Environmental Screen- ing Levels(ESLs). The source of these volatile organic compounds(VOCs)was not identified. VOCs and semi-volatile organic compounds(SVOCs)were not detected in soil samples,with the exception of chlorobenzene and petroleum hydrocarbons(TPH)as diesel at concentrations well below ESLs. Metal concentrations were within typical background concentrations for the Bay Area. Chromium and cobalt were above ESLs, likely due to the presence of naturally occurring serpentinite in the soils.18 '�Federal Emergency Management Agency,2009.Flood Insurance Rate Map,City of Cupertino.Community Panel No.060339-0209-H.Website:www.fema.gov/hazard/map/indexshtm(accessed April 3,2012). �$Erler&Kalinowski,Inc.,2006e.Phase I Environmental Site Assessment and Subsurface Investigations Report, ]0501 North Tantau Avenue, Cupertino, California.April 20. 15 LSA ASSOCIATES, INC. The exposure of construction workers and the public to existing or previously unknown contamina- tion in soil and/or groundwater, other safety hazards encountered during site grading and excavation activities, or hazardous materials following project development could result in adverse health effects. However, implementation of COA HAZ-2,which requires an Environmental Site Management Plan (ESMP),would reduce impacts associated with potential hazardous materials in soil, soil gas,and groundwater at the project site to a less-than-significant level. c. Airport Proximity. San Jose International Airport is the closest airport to the project site, and is located approximately 5.5 miles east of the site. The Santa Clara County Airport Land Use Com- mission(ALUC)has adopted a Land Use Plan for areas surrounding San Jose International Airport, which incorporates the airspace protection criteria provided in FAR Part 77. The project site is not located within any protected airspace zones defined by the ALUC or within the vicinity of a private airstrip, and has no heliports listed by the FAA. Therefore, development of the proposed project would have a less-than-significant impact related to airport hazards. d. School Proximity. Making Friends Preschool is located less than '/4-mile east of the project site. The use of hazardous materials during construction of the proposed project would not expose occupants of this school(or other sensitive receptors in the vicinity of the site)to significant health risks,with implementation of COAs HAZ-la and HAZ-Ib. e. Emergency Response Plan. Development of the proposed project would not be expected to conflict with City of Cupertino and Santa Clara County Emergency Operations Plans because access on public streets around the site would remain unchanged with implementation of the project. In addition, a 20-foot-wide emergency access route would be provided within the site for the duration of the project. f. Wildland Fires. CAL FIRE confirms the observations of LSA staff that the project site is not located within or adjacent to a Very High Fire Hazard Severity Zone. Therefore, development of the proposed project would have no impact related to wildland fire hazards. 10. Transportation and Circulation Because the proposed project would be dismantled after 3 years, it would have no permanent effect on traffic patterns or volumes. Emergency access to the project site would primarily be via North Tantau Avenue through the existing unoccupied parking lot of Building RC2. Access points to the project site are located in the northwestern and southeastern corners of the project site, and a 20-foot fire lane would be established that would provide emergency access through the site. During construction of the RC2 Annex,project materials would be brought to the site primarily via North Tantau Avenue(a secondary truck access route would also be established from Pruneridge Avenue). Construction vehicles and construction workers arriving and departing the site would tem- porarily add traffic to North Tantau Avenue and Pruneridge Avenue. Given the short duration of the construction phase(approximately 6 months)and the relatively small number of trips generated by workers and by the transport of construction materials to the project site, impacts to traffic volumes would be less than significant. COA TRANS-1 would ensure that construction vehicle traffic is managed to avoid conflicts with pedestrians,cyclists, and other vehicle traffic in the area. Adequate parking(approximately 89 spaces)would be provided to the west of the site during the construction period and all construction equipment would be stored on-site. 16 LSA ASSOCIATES, INC. The proposed project would not change access along Pruneridge Avenue or North Tantau Avenue, ar other roads in the vicinity of the site. Therefore,the operation of t11e project would not conflict with adopted policies,plans, or programs regarding public transit, bicycle, or pedestrian facilities. During its 3 years of operation,the up to 30 employees who may occupy the RC2 Annex would contribute to traffic volumes on local and regional roadways. However,these contributions would be less than significant in the context of the short-term use of the project and the overall capacity of the roadway system.No measurable changes in level of service during peak periods are expected. Therefore,the proposed project would not conflict with any applicable measures of effectiveness for the performance of the circulation system; conflict with an applicable congestion management program; result in a change in air traffic patterns; or substantially increase hazards due to a design feature; or result in inadequate emergency access. 11. Noise Two types of short-term noise would occur during construction of the proposed building. The first type would be from construction crew commutes and the transport of construction equipment and materials to the project site. The second type would be from noise generated during construction activities. Implementation of COA NOI-1 would ensure potential temporary noise impacts would be less than significant. COA NOI-1 would ensure that: 1)all construction equipment would be equipped with appropriate high-quality noise muffling and abatement devices; 2) all stationary construction equipment would be placed so that emitted noise is directed away from sensitive receptors nearest to the project site(i.e.,residential uses to the east of North Tantau Avenue); and 3)to the extent feasible, on-site equipment staging areas be located so as to maximize the distance between construction- related noise sources and noise-sensitive receptors nearest the project site during all project construc- tion. Operation of the project(including activity associated with the up to approximately 30 on-site employees)would incrementally increase noise levels in the vicinity of the site.However,this increase in noise is expected to be modest, as the project would not generate a large amount of vehicle traffic and project activities would be generally confined to the interior of the RC2 Annex(thus reducing the generation of noise in outdoor areas). 12. Greenhouse Gas Emissions Due to the small scale of the project,the short duration of the project construction period,and the temporary use of the project facilities,no significant impacts related to greenhouse gas emissions are expected to occur.19 The already less-than-significant emissions of greenhouse gases associated with the project would be further reduced through energy efficiency measures incorporated into the project, including shading on the southern exposure, rooftop photovoltaic cells,and the use of natural light and ventilation systems enabled by the rooftop penthouse. Therefore,the proposed project would not generate greenhouse gas emissions that would have a significant impact on the environment or conflict with an applicable plan,policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases. 19 Bay Area Air Quality Management District,2011.California Environmental QualityAct:Air Qualiry Guidelines. May. 17 LSA ASSOCIATES, INC. 13. Air Quality Air pollutant emissions associated with the proposed project would primarily occur in association with construction activities(such as excavation and vehicle/equipment use)and operation of the RC2 Annex(i.e.,emissions associated with building-related energy use). Construction vehicle traffic,the use of construction equipment, and wind blowing over exposed earth would emit e�aust and dust that could affect local and regional air quality. Construction activities are also a source of organic gas emissions. During grading and construction activities,trucks and earth-moving equipment would produce short-term air emissions, including ozone precursors,carbon monoxide, and coarse particulate matter(PM�o). The implementation of Bay Area Air Quality Man- agement District(BAAQMD)best management practices would reduce construction dust and emissions to a less-than-significant level. In addition,COA AIR-1, which would be incorporated as part of the project,would ensure that construction-related air quality impacts that could be caused by vehicle emissions are avoided or reduced to less-than-significant levels. Because the proposed project is a temporary use, long-term operational emissions resulting from vehicle trips to and from the project site would not be substantial. In addition,energy use(and related emissions)associated with equipment testing and other activities expected to occur in the RC2 Annex are not expected to be significant. Energy-related emissions would be further reduced through energy efficiency measures incorporated into the project, including shading on the southern exposure, rooftop photovoltaic cells,and the use of natural light and ventilation systems enabled by the rooftop penthouse. The proposed project would not emit substantial air pollutants or odors, and would not have long-term air quality impacts. As a result,the proposed project would not conflict with or obstruct implementation of the applicable air quality plan; violate any air quality standard or contrib- ute to an air quality violation; result in a cumulatively considerable net increase in any criteria pollut- ants; expose sensitive receptors to substantial pollutant concentrations;or create objectionable odors. 14. Public Services and Utilities The proposed project would result in the construction of a temporary building on an existing parking lot in an urban area. Because no housing would be constructed as part of the proposed project, and employment associated with the project would be modest(up to 30 employees may occupy the annex structure),the proposed project would not substantially increase fire,police, school or other public services,which are already provided to this urban area. The project site and surrounding area are served by existing utilities.Although these utilities would be extended into the project site to serve the RC2 Annex, needed extensions would be minor and would not result in significant secondary environmental impacts. The project applicant would work with each utility provider to ensure that utility service to surrounding areas is not interrupted. There- fore, impacts related to public services and utilities would be less than significant. D. CONDITIONS OF APPROVAL The following conditions of approval would be imposed on the proposed project and would substan- tially mitigate environmental effects. These development standards incorporate development policies and standards from various adopted plans, policies, and ordinances. 18 LSA ASSOCIATES, INC. COA AES-1: The project sponsor shall submit a final landscape plan to the City,which shall be reviewed by the Community Development Department prior to the issuance of a building permit. The City may require changes to the landscape plan to increase temporary plantings to screen the visibility of the RC2 Annex,maintain the vegetated visual character of the existing site, and reduce unneces- sary tree removal. COA AES-2: The project sponsor shall comply with the City's commercial lighting standards. COA BIO-1:A qualified biologist shall conduct surveys prior to tree pruning,tree removal,ground disturbing activities, or construction activities on the site to locate active nests used by native bird species on or immediately adjacent to the site. If construction will occur during the nesting season (February 1 to August 31),preconstruction surveys shall be conducted no more than 14 days prior to the start of pruning, construction, or ground disturbing activities. Preconstruction surveys shall be repeated at 14-day intervals until construction has been initiated in the area. Locations of active nests shall be described and protective measures implemented. Protective measures shall include establish- ment of clearly delineated (with uniquely identifiable fencing, such as orange construction fencing or equivalent)exclusion zones around each nest site as determined by a qualified wildlife biologist, taking into account the species of birds nesting on-site and their tolerance for disturbance. In general, exclusion zones shall be a minimum of 300 feet from the drip line of the nest tree or nest for raptors and 50 feet for passerines and other species. The active nest sites within an exclusion zone shall be monitored on a weekly basis throughout the nesting season to identify signs of disturbance or to determine if the nest has been abandoned or is no longer active. The radius of an exclusion zone may be increased by the project biologist if project activities are determined to be adversely affecting the nesting birds:Exclusion zones may be reduced by the project biologist only in consultation with the California Department of Fish and Game(CDFG). The protection measures shall remain in effect until the young have left the nest and are foraging independently or the nest is no longer active. A report shall be submitted to the City of Cupertino and CDFG at the end of the construction season documenting the observations made during monitoring and protection measures shall be imple- mented. Preconstruction surveys are not required for tree removal,tree pruning,or construction activities outside the nesting period. COA CULT-1: If archaeological deposits are encountered during project subsurface construction when an archaeological monitor is not present, all ground-disturbing activities within 25 feet shall be redirected and a qualified archaeologist contacted to assess the situation, consult with agencies as appropriate, and make recommendations for the treatment of the discovery. The project applicant shall inform its contractor(s)of the sensitivity of the project area far archaeological deposits. The City shall verify that the following directive has been included in the appropriate contract documents: "If prehistoric or historical archaeological deposits are discovered during project activities, all work within 25 feet of the discovery shall be redirected and a qualified archaeologist contacted to assess the situation,consult with agencies as appropriate, and make recommendations regard- ing the treatment of the discovery. Project personnel shall not collect or move any archaeological materials or human remains and associated materials.Archaeological resources can include flaked-stone tools(e.g.,projectile points,knives, choppers)or obsidian, chert,basalt,or quartzite toolmaking debris; bone tools;culturally darkened soil(i.e., midden soil often containing heat- affected rock, ash and charcoal, shellfish remains, faunal bones, and cultural materials); and 19 LSA ASSOCIATES, INC. stone-milling equipment(e.g., mortars,pestles,handstones).Prehistoric archaeological sites often contain human remains." COA CULT-2: Should paleontological resources be encountered during project subsurface construc- tion activities,all ground-disturbing activities within 25 feet shall be redirected and a qualified pale- ontologist contacted to assess the situation,consult with agencies as appropriate, and make recom- mendations for the treatment of the discovery. If found to be significant,and project activities cannot avoid the paleontological resources,adverse effects to paleontological resources shall be mitigated. Mitigation may include monitoring,recording the fossil locality,data recovery and analysis,a final report, and accessioning the fossil material and technical report to a paleontological repository. Public educational outreach may also be appropriate. Upon completion of the assessment,a report docu- menting methods, findings,and recommendations shall be prepared and submitted to the City of Cupertino for review,and(if paleontological materials are recovered)a paleontological repository, such as the University of California Museum of Paleontology. The project applicant shall inform its contractor(s) of the sensitivity of the project area for paleon- tological resources. The City shall verify that the following directive has been included in the appropriate contract documents: "The subsurface of the construction site may be sensitive for paleontological resources. If pale- ontological resources are encountered during project subsurface construction and a paleontolo- gist is not on-site, all ground-disturbing activities within 25 feet shall be redirected and a quali- fied paleontologist contacted to assess the situation,consult with agencies as appropriate, and make recommendations for the treatment of the discovery. Project personnel shall not collect or move any paleontological materials. Paleontological resources include fossil plants and animals,and such trace fossil evidence of past life as tracks.Ancient marine sediments may contain invertebrate fossils such as snails, clam and oyster shells, sponges, and protozoa;and vertebrate fossils such as fish,whale,and sea lion bones. Vertebrate land mammals may include bones of mammoth,camel, saber tooth cat,horse,and bison. Paleontological resources also include plant imprints, petrified wood, and animal tracks." COA CULT-3: If human remains are encountered during construction,the project shall implement COA CULT-1 (archaeological monitoring)to identify and treat any human remains that may be present. In addition, any human remains encountered during project ground-disturbing activities shall be treated in accordance with California Health and Safety Code Section 7050.5. The project applicant shall inform its contractor(s) of the sensitivity of the project site for human remains. The City shall verify that the following directive has been included in the appropriate contract documents: "If human remains are uncovered,work within 25 feet of the discovery shall be redirected and the County Coroner notified immediately.At the same time, an archaeologist shall be contacted —if one is not already on site—to assess the situation and consult with agencies as appropriate. Project personnel shall not collect or move any human remains or associated materials. If the human remains are of Native American origin,the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage 20 LSA ASSOCIATES, INC. Commission will identify a Native American Most Likely Descendant to inspect the site and provide recommendations for the proper treatment of the remains and associated grave goods." COA GEO-1: Prior to the issuance of any site-specific grading or building permits, a design-level geotechnical report shall be prepared and submitted to the City of Cupertino Building Department for review and approval and in accordance with adopted City standards. The structural designs shall adhere to the 2010 California Building Code or the appropriate building code as adopted by the City of Cupertino. Examples of the kinds of ineasures that would typically be used to meet these require- ments include pile-supported foundations, use of pre-stressed concrete materials, slab reinforcement, compaction specifications, drainage requirements, use of control joints, and appropriate safety factors. The report shall identify specific building techniques appropriate for minimizing damage from seis- mic events, including liquefaction and lateral spreading. In addition,the following requirement for the geotechnical and soils report shall be met: • The seismic hazard analysis presented in the geotechnical report shall include an evaluation of liquefaction hazards in the Calabazas Creek area,and shall confonn to the California Division of Mines and Geology recommendations presented in the Guidelines for Evaluating and Mitigating Seismic Hazards in California.20 • Design review for the project shall include evaluation of fixtures, furnishings, and the fasteners with the intent of minimizing collateral injuries to building occupants from falling fixtures or furnishings during the course of a violent seismic event. All design criteria and specifications set forth in the design-level geotechnical report shall be imple- mented as a condition of project approval. This report shall address the final specifications for design and construction intended to limit the effects of seismic hazards to structures and utilities, including but not limited to: foundation design, driven piles, utility conidor design, excavation sub-grade prepa- ration, fill materials and compaction specifications,retaining walls and concrete pavement specifica- tions, and drainage and dewatering design. This report shall be completed as a condition of approval of the vesting tentative map or adoption of the development agreement. COA GEO-2: The design-level geotechnical report shall include recommendations for foundations and improvements that take into consideration the potential effects of expansive and corrosive soils. The report shall be submitted to the City of Cupertino Building Department for review and approval. All design criteria and specifications set forth in the design-level geotechnical report shall be imple- mented as a condition of project approval. COA HYD-1: The project sponsor shall prepare and implement a Storm Water Management Plan for the project that includes the following elements: • A description of the existing and proposed site drainage network and connections to drainage off- site. • A division of the site into separate drainage areas(if appropriate),and an inventory of the current and proposed impervious surfaces in each area. 20 California Geological Survey,2008.Guidelines for Evaluating and d�litigating Seisrnic Hazards in California, CGS Special Publication 117. 21 LSA ASSOCIATES, INC. • A description of the treatment option for each drainage area(e.g., self-retaining, self-treating, or treatment/flow facility). • Preliminary design, including calculations,for infiltration,treatment, or flow-control facilities, demonstrating their adequacy. • An inventory of'potential contaminant sources and strategies for the protection of stormwater quality,to the maximum extent practicable. • A draft Operations and Maintenance plan, including a description of maintenance requirements, personnel assigned to that maintenance, and the establishment of a means for which the Opera- tions and Maintenance Plan will be funded and implemented in perpetuity. In addition,the project sponsor shall prepare a Storm Water Pollution Prevention Plan(SWPPP)to reduce impacts to surface water during the construction period. The SWPPP shall be designed to meet the following objectives: (1)all pollutants and their sources, including sources of sediment associated with construction, construction site erosion, and all other activities associated with construction activity are controlled; (2)where not otherwise required under a Regional Water Quality Control Board(RWQCB)permit, all non-stormwater discharges are identified and either eliminated,con- trolled, or treated; (3) site Best Management Practices(BMPs)are effective and result in the reduc- tion or elimination of pollutants in storm water discharges and authorized non-stormwater discharges from construction activity to the appropriate standard; and(4) stabilization BMPs installed to reduce or eliminate pollutants after construction are completed. COA HAZ-la: The contractor(s) shall designate storage areas suitable for material delivery, storage, and waste collection. These locations must be as far away from catch basins,gutters, drainage courses, and Calabazas Creek as feasible.All hazardous materials and wastes used or generated during project site development activities shall be labeled and stored in accordance with applicable local, State, and federal regulations. In addition, an accurate up-to-date inventory, including Material Safety Data Sheets, shall be maintained on-site to assist emergency response personnel in the event of a hazardous materials incident. All maintenance and fueling of vehicles and equipment shall be performed in a designated,bermed area,or over a drip pan that will not allow runoff of spills.

COA HAZ-lb: Emergency preparedness and response procedures shall be developed by the contrac- tor(s)for emergency notification in the event of an accidental spill or other hazardous materials emergency during project site preparation and development activities. These procedures shall include evacuation procedures, spill containment procedures, and reyuired personal protective equipment, as appropriate, in responding to the emergency. The contractor(s)shall submit these procedures to the City of Cupertino for approval prior to development activities. Compliance with these COAs may occur in coordination with compliance with the Stonn Water Pollution Prevention Plan and Best Management Practices required for the proposed project(see COA HYD-1). 22 LSA ASSOCIATES, INC. COA HAZ-2: Construction at the project site shall be conducted under a project-specific Environ- mental Site Management Plan(ESMP)that is prepared under the oversight of the RWQCB. The purpose of the ESMP is to protect construction workers,the general public,the environment,and future site occupants from subsurface hazardous materials previously identified at the project site and to address the possibility of encountering unknown contamination or hazards in the subsurface. The ESMP shall identify soil and groundwater analytical data collected on the project site during past investigations; identify management options for excavated soil and groundwater, if contaminated media are encountered during deep excavations; and identify monitoring, irrigation, or other wells requiring proper abandonment in compliance with local, State, and federal statutes and regulations. The ESMP shall include measures for identifying,testing,and managing soil and groundwater suspected of or known to contain hazardous materials. The ESMP will: 1)provide procedures for evaluating, handling, storing,testing, and disposing of soil and groundwater during project excavation and dewatering activities,respectively; 2)describe required worker health and safety provisions for all workers potentially exposed to hazardous materials in accordance with State and federal worker safety regulations;and 3)designate personnel responsible for implementation of the ESMP.

E. STATUTORY EXEMPTION ANALYSIS As discussed below,the project would be exempt from detailed CEQA review under Section 15268 of the CEQA Guidelines. Section 15268(Ministerial Projects)exempts from detailed environmental review projects that are ministerial projects. The following discusses the applicability of Section 15268. Section 15268 states: a) Ministerial projects are exempt from the requirements of CEQA. The determination of what is "ministerial"can most appropriately be made by the particular public agency involved based upon its analysis of its own laws, and each public agency should make such determination either as a part of its implementing regulations or on a case-by-case basis. 25 LSA ASSOCIATES, SNC. b) In the absence of any discretionary provision contained in the local ordinance or other law establishing the requirements for the permit,license, or other entitlement for use,the following actions shall be presumed to be ministerial: 1) Issuance of building permits. 2) Issuance of building licenses. 3) Approval of final subdivision maps. 4) Approval of individual utility service connections and disconnections. c) Each public agency should, in its implementing regulations or ordinances, provide an identifica- tion or itemization of its projects and actions which are deemed ministerial under the applicable laws and ordinances. d) Where a project involves an approval that contains elements of both a ministerial action and a discretionary action,the project will be deemed to be discretionary and will be subject to the requirements of CEQA. The proposed project is a temporary building and associated facilities that would be used to house testing facilities for new technologies and building materials. Project details are provided in Section B, Project Description.No significant adverse effects would result from the project as explained in Section C, Environmental Impact Analysis. The following describes how the project meets the provisions of Section 15268. The provisions are presented in italics, followed by a discussion of how the project meets each provision. a) Ministerial p�°ojects are exempt from the requirements of CEQA. The determination of what is "ministerial"can most appropriately be made by tlze particular public agency involved based upon its analysis of its own laws, and each public agency should make suclz determination either as a part of its inzplementing regulations or on a case-by-case basis. The proposed project is considered a ministerial project by the City of Cupertino because the project is a temporary use that would be approved via a Director's Approval, as described in Chapter 19.160, Temporary Uses,of the Cupertino Municipal Code. This chapter allows for administrative approval of a conditional use permit,authorizing the use of a site in any zoning district for a temporary use if the use would: 1)not be detrimental or injurious to property or improvements in the vicinity; 2)not be detrimental to the public,health, safety, general welfare,or convenience; and 3)would be located and conducted in a manner in accord with the Cupertino General Plan and the purposes of the Municipal Code.Z' The Director of Community Development must report her decision to the City Council and Planning Commission in time to allow an appeal of the decision within 14 calendar days. Support for the Director's Approval is contained in this memorandum and the staff report prepared for the project. A Director's Approval is considered a ministerial action because a conditional use permit for a temporary use is issued if certain conditions are met.Because no discretion is involved in the issuance of this permit,the permit is issued by City staff(and not a legislative body). 21 Cupertino,City of,201 I.Municipal Code,Cliapter 19.160, Temporary Uses. 26 LSA ASSOCIATES, INC. b) In the absence of any discretionary provision contained in the local ordinance or other law establishing the requirements for the permit, license, or other entitlement for use, the following actions shall be presumed to be ministerial: 1) Issuance of building permits. 2) Issuance of building licenses. 3) Approval offinal subdivision maps. 4) Approval of individual utiliry service connections and disconnections. As previously described,the proposed project is considered a ministerial project by the City of Cupertino because the project is a temporary use and would be subject to a conditional use permit that would be administratively granted. c) Each public agency sl�ould, in its implernenting regulations or ordinances,provide an identifica- tion or itemization of its projects and actions which are dee�ned�ninisterial under the applicable laws and ordinances. The City of Cupertino considers a temporary use to be a ministerial project under its Municipal Code. d) Where a project involves an approval that contains elements of both a ministerial action and a discretionary action, the project will be deemed to be discYetionary and will be subject to the requirements of CEQA. The proposed project does not involve an approval that contains elements of both a ministerial action and a discretionary action,and therefore would not be deemed to be discretionary,and would not be subject to detailed review pursuant to CEQA. F. CATEGORICAL EXEMPTION The project would also be eligible for a Categorical Exemption under Section 15311 (Accessory Structures)and Section 15332 (In-Fill Development Projects)of the CEQA Guidelines. These sections are excerpted below, and each is followed by a short explanation of the applicability of each class of exemption to the project. 15311.ACCESSORY STRUCTURES Class 11 consists of construction, or placenzent of minor structures accessory to (appurtenant to) existing comnzercial, industrial, or institutional facilities, including but not li�nited to: (a) On premise signs; (b) Small parking lots; (c)Placement of seasonal or temporary use items such as lifeguard towers, mobile food units, portable rest�•ooms, or similar items in generally the same locations from time to time in publicly owned parks, stadiunas, or other facilities designed for public use. The project would be considered an "Accessory Structure"pursuant to CEQA Guidelines Section 15311 because it would involve the construction of a temporary structure that would be accessory to 27 LSA ASSOCIATES, SNC. existing commercial and research and development facilities on property owned by Apple. The building would be used to test new technologies and building materials that would be utilized elsewhere on Apple's property. 15332.IN-FILL DEVELOPMENT PROJECTS Class 32 consists ofprojects characterized as in-fill development meeting the conditions described in this section. (a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations. (b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses. (c) Tlze project site has no value as habitat for endangered, rare or threatened species. (d)Approval of the project would not result in any significant effects relating to tra�c, noise, air qualiry, or water qualiry. (e) The site can be adequately served by all�-equired utilities and public services. The project would be considered an"In-Fill Development Project"pursuant to CEQA Guidelines Section 15332 because: the project would be consistent with applicable General Plan policies and zoning regulations(the proposed use is pennitted under the General Plan designation and zoning regulations on the site);the project would occur entirely within the City of Cupertino on a 2.9-acre site;the project site is developed with parking facilities and does not contain land with significant habitat value; with implementation of all identified conditions of approval,the project would not result in any significant effects related to traffic, noise, air quality, or water quality,as described in this memorandum; and the project site is currently adequately served by all required utilities and public services.
