EARTI-I GROUP
Final Rule (40 CFR Part 312) requires specific tasks be performed by or on behalf of the party seeking to qualify for Landowner Liability Protection under CERCLA (i.e., the User).

Per the ASTM standard, if the User has information that is material to Recognized Environmental Conditions in connection with the Site, such information should be provided to the Environmental Professional. This information includes: 1) specialized knowledge or experience of the User, 2) commonly known or reasonably ascertainable information within the local community, and 3) knowledge that the purchase price of the Site is lower than the fair market value due to contamination . A search of title records for environmental liens and activity and use limitations also is required.

3.1 ENVIRONMENTAL LIENS OR ACTIVITY AND USE LIMITATIONS An environmental lien is a financial instrument that may be used to recover past environmental cleanup costs. Activity and use limitations (AULs) include other environmental encumbrances, such as institutional and engineering controls. Institutional controls (ICs) are legal or regulatory restrictions on a property's use, while engineering controls (ECs) are physical mechanisms that restrict property access or use.

The regulatory agency database report described in Section 4.1 did not identify the Site as being in 1) US EPA databases that list properties subject to land use restrictions (i.e., engineering and institutional controls) or Federal Superfund Liens or 2) lists maintained by the California Department of Toxic Substances Control (DTSC) of properties that are subject to AULs or environmental liens where the DTSC is a lien holder.

ASTM E1527-21 categorizes the requirement to conduct a search for Environmental Liens and AULs as a User responsibility. A search of land title records for environmental liens and AULs was not within the scope of the current Phase I ESA and the User did not provide such search results to Cornerstone .

3.2 SPECIALIZED KNOWLEDGE AND COMMONLY KNOWN OR REASONABLY

ASCERTAINABLE INFORMATION
Based on information provided by or discussions with David J. Powers & Associates, we understand that David J. Powers & Associates does not have specialized knowledge or experience , commonly known or reasonably ascertainable information regarding the Site, or other information that is material to Recognized Environmental Conditions .

SECTION 4: RECORDS REVIEW

4.1 STANDARD ENVIRONMENTAL RECORD SOURCES
Cornerstone conducted a review of federal, state and local regulatory agency database records provided by Environmental Data Resources (EDR) to evaluate the likelihood of contamination incidents at and near the Site. The database sources and the search distances are in general accordance with the requirements of ASTM E1527-21. A list of the database sources reviewed, a description of the sources, and a radius map showing the location of reported facilities relative to the project Site are attached in Appendix A.

CORNERSTONE

EARTH GROUP
The purpose of the records review was to obtain reasonably available information to help identify Recognized Environmental Conditions . Accuracy and completeness of record information varies among information sources, including government sources. Record information is often inaccurate or incomplete . The Environmental Professional is not obligated to identify mistakes or insufficiencies or review every possible record that might exist with respect to the Site. The customary practice is to review information from standard sources that is reasonably ascertainable within reasonable time and cost constraints .

4.1.1 On-Site Database Listings
Memorial Park Ponds Repurposing was identified at the Site address on the California Integrated Water Quality System (CIWQS) database, a computer system used by the State and Regional Water Quality Control Boards to track information about places of environmental interest, manage permits and other orders, track inspections , and manage violations and enforcement activities . This listing appears to be associated recent construction activities involving the removal of decorative, concrete lined ponds at the park.

4.1.2 Adjoining Property Database Listings and Nearby Spill Incidents Based on the information presented in the agency database report, no off-Site spill incidents were reported that appear likely to significantly impact soil, soil vapor or groundwater beneath the Site. The potential for impact was based on our interpretation of the types of incidents, the locations of the reported incidents in relation to the Site and the assumed groundwater flow direction . A few businesses on adjoining properties were identified on regulatory agency databases relating primarily to regulatory filings associated with hazardous material use/storage, and generation or disposal of hazardous wastes. Such listings are common for commercial facilities in urban settings and are not indicative of hazardous material releases; thus, further review of records associated with these listings does not appear warranted.

4.2 ADDITIONAL ENVIRONMENTAL RECORD SOURCES
The following additional sources of readily ascertainable public information for the Site also were reviewed during this Phase I ESA.

4.2.1 City and County Agency File Review
Cornerstone obtained available files pertaining to the Site at the following public agencies: the Cupertino Building Department (BD), Santa Clara County Fire Department (SCCFD), and the Santa Clara County Department of Environmental Health (DEH).

The DEH and SCCFD indicated that they had no files pertaining to hazardous materials use at the Site.

Building Department files for 21251 Stevens Creek Boulevard contained permit records dated between 1999 and 2017 for construction of the existing Senior Center building and subsequent repairs and alterations. Permits dated between 2010 and 2016 were for cellular telephone antenna equipment installation. A 2022 permit was for the in-progress pond repurposing project at Memorial Park. The files additionally contained a 1980 Certificate of Occupancy for a former "Senor Citizen Building."

Building Department files for 10185 North Stelling Road contained permit records dated between 1988 and 2021 associated with construction of the Quinlan Community Center and various subsequent alterations and repairs.

4.2.2 Geologic Energy Management Division Maps
To evaluate the presence of oil or gas wells on-Site and in the immediate Site vicinity, maps available on-line at the California Department of Conservation, Geologic Energy Management Division (CalGEM) website were reviewed. Review of the available map for the Site area did not show oil or gas wells on-Site or on the adjacent properties.

SECTION 5: PHYSICAL SETTING
We reviewed readily available geologic and hydrogeologic information to evaluate the likelihood that chemicals of concern released on a nearby property could pose a significant threat to the Site and/or its intended use.

5.1 RECENT USGS TOPOGRAPHIC MAP
A 2018 USGS 7.5 minute topographic map was reviewed to evaluate the physical setting of the Site. The Site's elevation is approximately 280 feet above mean sea level; topography in the vicinity of the Site slopes downward gently to the northeast towards the San Francisco Bay.

5.2 HYDROGEOLOGY
Based on our experience and information presented in the California Geotracker database pertaining to nearby properties, groundwater beneath the Site is likely present at depths of greater than 100 feet. Groundwater likely flows toward the northeast.

SECTION 6: HISTORICAL USE INFORMATION
The objective of the review of historical use information is to develop a history of the previous uses of the Site and adjoining properties in order to help identify the likelihood of past uses having led to Recognized Environmental Conditions at the Site. The ASTM standard requires the identification of all obvious uses of the Site from the present back to the Site's first developed use, or back to 1940, whichever is earlier, using reasonably ascertainable standard historical sources. The identification of obvious uses of adjoining properties also is required.

6.1 HISTORICAL SUMMARY
The historical sources reviewed are summarized below. The results of our review of these sources are summarized in Table 4.
■ Historical Aerial Photographs: We reviewed aerial photographs dated between 1939 and 2016 obtained from EDR of Shelton, Connecticut ; copies of aerial photographs reviewed are presented in Appendix B.

SECTION 7: SITE RECONNAISSANCE
We performed a Site reconnaissance to evaluate current Site conditions and to attempt to identify Site Recognized Environmental Conditions. The results of the reconnaissance are discussed below. Additional Site observations are summarized in Table 6. Photographs of the Site are presented in Section 7.2.1.

7.1 METHODOLOGY AND LIMITING CONDITIONS
To observe current Site conditions (readily observable environmental conditions indicative of a significant release of hazardous materials), Cornerstone staff Stason I. Foster, P.E. visited the Site on September 26, 2022. The Site reconnaissance was conducted by walking representative areas of the Site, including the interiors of the on-Site structures , the periphery of the structures and the Site periphery. The Site also was observed from adjacent public thoroughfares. Cornerstone staff only observed those areas that were reasonably accessible , safe, and did not require movement of equipment , materials or other objects. Physical obstructions that limited our ability to view the ground surface at the Site included the existing buildings and associated paved vehicle drives and parking areas (typical of developed properties) .

7.2 OBSERVATIONS
At the time of our visit, the Site was developed with Cupertino Memorial Park, the Cupertino Senior Center, and the Quinlan Community Center.

The Cupertino Senior Center and Quinlan Community Center buildings were observed to consist of various rooms used for events, classes and activities, as well as general office space and kitchen facilities . Cupertino Historical Museum and a preschool facility also operated within the community center building.

Memorial Park was observed to consist of open space, tennis courts, athletic fields, and picnic and playground areas. Grading associated with a project to remove former concrete lined decorative ponds was observed to be in progress. A cellular telephone antenna tower and fenced equipment enclosure also were present.

Two wood-framed sheds with concrete floor slabs were observed within the park that contained grounds maintenance equipment. Hazardous materials observed within the sheds consisted primarily of gasoline that was stored in safety cans within a flammable materials storage cabinet, weed killer (Roundup®) contained in portable backpack pump sprayers and marking paint for sports fields.

Facility maintenance rooms were observed in both the Cupertino Senior Center and Quinlan Community Center buildings that contained paints and other common building maintenance supplies. General housekeeping within the facility maintenance rooms, as well as the grounds maintenance sheds, appeared orderly and no evidence of significant chemical spills was readily apparent.

Electricity and/or natural gas fuel sources appeared to be used for building heating/cooling purposes. Potable water appeared to be supplied by the local water service provider. The buildings presumably are connected to the publicly owned sanitary sewer system; no on-Site septic systems were obvious. On-Site storm water catch basins appeared to discharge via below ground piping to the City's storm water drainage system. Electrical transformer owned by PG&E were observed on concrete pads within the park and near the community center and senior center buildings. No evidence of transformer oil leaks was observed.

SECTION 8: ENVIRONMENTAL QUESTIONNAIRE AND INTERVIEWS

8.1 ENVIRONMENTAL QUESTIONNAIRE/ CURRENT OWNER AND OCCUPANT

INTERVIEW
To help obtain information on current and historical Site use and use/storage of hazardous materials on-Site, we provided an environmental questionnaire for completion by the Site owner (City of Cupertino). The completed questionnaire is attached in Appendix D. The information provided on the questionnaire appears generally consistent with our on-Site observations and information obtained from other data sources. No information indicative of Recognized Environmental Conditions was reported on the questionnaire .

8.2 INTERVIEWS WITH PREVIOUS OWNERS AND OCCUPANTS
Contact information for previous Site owners and occupants was not provided to us. Therefore , interviews with previous Site owners and occupants could not be performed.

8.3 INTERVIEWS WITH STATE AND/OR LOCAL GOVERNMENT OFFICIALS Per the ASTM Standard, a reasonable attempt should be made to interview at least one staff member of any one of the following types of state and/or local government agencies: fire department , health department, building department , or other agency having jurisdiction over hazardous waste disposal or other environmental matters in the area.

The Cupertino Building Department, Santa Clara County Fire Department, and the Santa Clara County DEH were contacted during this study. The DEH is the Certified Unified Program Agency (CUPA) responsible for implementing California's Unified Hazardous Waste and Hazardous Materials Management regulatory program for properties within Cupertino; the Fire Department also is a Participating Agency (PA). Files pertaining to the Site were requested from each of these agencies; a summary of the information obtained was discussed in Section

EARTH GROUP
SECTION 9: FINDINGS, OPINIONS, AND CONCLUSIONS (WITH

RECOMMENDATIONS)
Cornerstone performed this Phase I ESA in general conformance with ASTM E1527-21 to support David J. Powers & Associates in evaluation of Recognized Environmental Conditions.

Our findings , opinions and conclusions are summarized below.

9.1 HISTORICAL SITE USAGE
Based on the information obtained during this study, the Site historically was occupied by orchards, along with what appear to have been several residences and associated outbuildings .

During the mid-1970s, Memorial Park facilities (e.g., tennis courts and baseball field) were constructed on the western portion of the Site. A former senior center building was constructed at the southwest corner of the Site during the early 1980s. The existing Quinlan Community Center was constructed on the eastern portion of the Site during the late 1980s. The existing Cupertino Senior Center building was constructed in approximately 2000, replacing the former senior center building.

9.2 CHEMICAL STORAGE AND USE
Paints and other common building maintenance supplies were observed within facility maintenance rooms in both the Cupertino Senior Center and Quinlan Community Center buildings. Grounds maintenance sheds within Memorial Park were observed to contain gasoline that was stored in safety cans within a flammable materials storage cabinet, weed killer (Roundup®) contained in portable backpack pump sprayers and marking paint for sports fields.

General housekeeping within the facility maintenance rooms and the grounds maintenance sheds appeared orderly and no evidence of significant chemical spills was readily apparent.

9.3 AGRICULTURAL USE
The Site historically was used for agricultural purposes for several decades. Pesticides may have been applied to crops in the normal course of farming operations . Residual pesticide concentrations may remain in on-Site soil. If elevated concentrations of agricultural chemicals are present, mitigation or soil management measures may be required. We recommend performing soil sampling to evaluate if agricultural chemicals are present at concentrations that may pose a risk to human health. At agricultural properties, pesticides often were stored within structures such as barns or sheds. The recommended sampling should include an evaluation of these former structures, along with the agricultural field areas.

9.4 LEAD-BASED PAINT AND TERMITE CONTROL PESTICIDES
In 1978, the Consumer Product Safety Commission banned lead-containing paints and coatings sold for consumer use. Some lead-containing products, such as industrial coatings, however, are still allowed. Based on the age of the existing Cupertino Senior Center and Quinlan Community Center buildings, lead-containing paint is not likely to be present. Some of the Memorial Park structures (such a restrooms) appear to have been constructed during the 1970s and have greater potential for the presence of lead-containing paint. If demolition is planned, the removal of lead-containing paint is not required if it is bonded to the building materials .

However, if the lead-containing paint is flaking, peeling, or blistering, it should be removed prior to demolition. In either case, applicable OSHA regulations must be followed; these include Cupertino Memorial Park, 10185 North Stelling Road and
21251 Stevens Creek Boulevard , Cupertino, California

EARTI-I GROUP
requirements for worker training, air monitoring and dust control, among others. Any debris or soil containing lead must be disposed appropriately .

Soil adjacent to structures, if painted with lead-containing paint, can become impacted with lead as a result of the weathering and/or peeling of painted surfaces. Soil near wood framed structures also can be impacted by pesticides historically used to control termites . No information was identified during this study documenting the use of lead based paint or termite control pesticides on-Site; however, if previously used, residual pesticide and lead concentrations may remain in on-Site soil. Lead and/or pesticides often are identified in soil near old residences and outbuildings , such as those historically located on-Site. We recommend that shallow soil at the former structure locations be evaluated for the possible presence of lead and pesticides.

9.5 ASBESTOS CONTAINING BUILDING MATERIALS (ACBMS)
Based on the age of the existing Cupertino Senior Center and Quinlan Community Center buildings, it is unlikely that these building materials contain asbestos. Some of the Memorial Park structures ( such a restrooms) appear to have been constructed during the 1970s and have greater potential for the presence of asbestos. If demolition, renovation, or re-roofing of the buildings is planned, an asbestos survey may be required by local authorities or National Emissions Standards for Hazardous Air Pollutants (NESHAP) guidelines . NESHAP guidelines require the removal of potentially friable ACBMs prior to building demolition or renovation that may disturb the ACBM.

9.6 IMPORTED SOIL
If the planned development will require importing soil for Site grading, we recommend documenting the source and quality of imported soil. The DTSC's October 2001 Clean Fill Advisory provides useful guidance on evaluating imported fill.

9.7 POTENTIAL ENVIRONMENTAL CONCERNS WITHIN THE SITE VICINITY Based on the information obtained during this study, no hazardous material spill incidents have been reported in the Site vicinity that would be likely to significantly impact the Site.

9.8 DATA GAPS
ASTM Standard E1527-21 requires the Environmental Professional to comment on significant data gaps that affect our ability to identify Recognized Environmental Conditions . A data gap is a lack of or inability to obtain information required by the ASTM Standard despite good faith efforts by the Environmental Professional to gather such information. A data gap by itself is not inherently significant; it only becomes significant if it raises reasonable concerns. No significant data gaps were identified during this Phase I ESA.

9.9 DATA FAILURES
As described by ASTM Standard E1527-21, a data failure occurs when all of the standard historical sources that are reasonably ascertainable and likely to be useful have been reviewed and yet the historical research objectives have not been met. Data failures are not uncommon when attempting to identify the use of a Site at five year intervals back to the first use or to 1940 Cupertino Memorial Park, 10185 North Stelling Road and

(whichever is earlier). The ASTM Standard requires the Environmental Professional to comment on the significance of data failures and whether the data failure affects our ability to identify Recognized Environmental Conditions . A data failure by itself is not inherently significant ; it only becomes significant if it raises reasonable concerns. No significant data failures were identified during this Phase I ESA.

9.10 RECOGNIZED ENVIRONMENTAL CONDITIONS
Cornerstone has performed a Phase I ESA in general conformance with the scope and limitations of ASTM E1527-21. This assessment identified the following Recognized Environmental Conditions 2.
• The Site historically was used for agricultural purposes. There is a potential that residual pesticides could remain in Site soil. If present, this soil may require appropriate management.
• Soil adjacent to structures that are painted with lead-containing paint can become impacted with lead as a result of the weathering and/or peeling of painted surfaces. Soil near wood-framed structures also can be impacted by pesticides historically used to control termites . There is a potential that residual lead and pesticide concentrations could remain in on-Site soil resulting from prior on-Site structures.

This assessment did not identify any Controlled Recognized Environmental Conditions 3 or Historical Recognized Environmental Conditions 4 associated with the Site.

SECTION 10: LIMITATIONS
Cornerstone performed this Phase I ESA to support David J. Powers & Associates in evaluation of Recognized Environmental Conditions associated with the Site. David J. Powers & Associates understands that no Phase I ESA can wholly eliminate uncertainty regarding the potential for Recognized Environmental Conditions to be present at the Site. This Phase I ESA is intended to reduce, but not eliminate, uncertainty regarding the potential for Recognized Environmental Conditions . David J. Powers & Associates understands that the extent of information obtained is based on the reasonable limits of time and budgetary constraints.

Findings, opinions, conclusions and recommendations presented in this report are based on readily available information, conditions readily observed at the time of the Site visit, and/or information readily identified by the interviews and/or the records review process. Phase I ESAs are inherently limited because findings are developed based on information obtained from a non-intrusive Site evaluation. Cornerstone does not accept liability for deficiencies, errors, or 2 Recognized Environmental Condition means 1) the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment ; 2) the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment ; or 3) the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment.
3 A Recognized Environmental Condition that has been addressed to the satisfaction of the applicable regulatory agency with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls . 4 A previous release of hazardous substances or petroleum products affecting the Site that has been addressed to the satisfaction of the applicable regulatory agency and meeting unrestricted use criteria established by the applicable regulatory agency without subjecting the Site to any controls .

misstatements that have resulted from inaccuracies in the publicly available information or from interviews of persons knowledgeable of Site use. In addition, publicly available information and field observations often cannot affirm the presence of Recognized Environmental Conditions ; there is a possibility that such conditions exist. If a greater degree of confidence is desired, soil, groundwater , soil vapor and/or air samples should be collected by Cornerstone and analyzed by a state-certified laboratory to establish a more reliable assessment of environmental conditions .

Cornerstone acquired an environmental database of selected publicly available information for the general area of the Site. Cornerstone cannot verify the accuracy or completeness of the database report, nor is Cornerstone obligated to identify mistakes or insufficiencies in the information provided (ASTM E1527-21, Section 8.1.3). Due to inadequate address information, the environmental database may have mapped several facilities inaccurately or could not map the facilities . Releases from these facilities, if nearby, could impact the Site.

David J. Powers & Associates may have provided Cornerstone environmental documents prepared by others. David J. Powers & Associates understands that Cornerstone reviewed and relied on the information presented in these reports and cannot be responsible for their accuracy.

This report, an instrument of professional service, was prepared for the sole use of David J.

Powers & Associates and may not be reproduced or distributed without written authorization from Cornerstone . Cornerstone makes no warranty, expressed or implied, except that our services have been performed in accordance with the environmental principles generally accepted at this time and location.

10.1 REPORT VIABILITY

In accordance with your request and authorization, we have performed a geotechnical evaluation for the Memorial Park Project located at 21121 Stevens Creek Boulevard in Cupertino, California (Figure 1). The purpose of our study was to assess the geotechnical conditions at the site and provide recommendations for the design and construction of the proposed improvements. 2 SCOPE OF SERVICES
The services we performed included the following:
• Review of pertinent background data, including aerial photographs and published geologic, seismic, and soils maps and literature.
• A site reconnaissance to observe the general site conditions and to mark the proposed locations for subsurface exploration.
• Coordination with Underground Service Alert (USA) to locate and mark underground utilities in the vicinity of the subsurface exploration locations. • Subcontract a private underground utility survey to further check the exploration locations for underground utility conflicts.
• Procurement of an encroachment permit from the City of Cupertino’s Department of Public Works.
• S ubsurface exploration consisting of seventeen (17) exploratory borings advanced up to 15 feet below existing grade. A representative of Ninyo & Moore logged the subsurface conditions exposed in the borings and collected bulk and relatively undisturbed soil samples for laboratory tests. The borings were backfilled with cement grout , in compliance with the Santa Clara Valley Water District regulations. Drill cuttings were off hauled from the site. • L aboratory testing of selected soil samples to evaluate the geotechnical properties of the subsurface materials including in- situ soil moisture content and density, soil gradation, Atterberg limits, expansion index, R-value, and soil corrosivity. • D ata compilation and engineering analysis of the information obtained from our background review, subsurface evaluation, and laboratory testing.
• Preparation of this geotechnical report presenting our findings and conclusions regarding the subsurface conditions encountered at the project site, and our geotechnical recommendations for the design and construction of the proposed improvements. 3 SITE DESCRIPTION AND BACKGROUND
The project site is located at 21121 Stevens Creek Boulevard in Cupertino, California (Figure 1).

The site is an “L” shaped lot that is bounded to the north by Christensen Drive, to the east by North Stelling Road and Anton Way, to the west by residential properties, and to the south Stevens Creek Boulevard and Alves Drive. Memorial Park is the largest and most well -used park in Cupertino. The 22-acre site includes lawns, a gazebo, an amphitheater, a lighted softball field, -

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 2

and six lighted tennis courts. Memorial Park houses the Cupertino Veterans Memorial which honors local veterans, and is adjacent to the Cupertino Senior Center, Quinlan Community Center, and Cupertino Sports Center. The site is relatively flat and lies at elevations of approximately between 286 to 296 feet above mean sea level (Google Earth, 2022). 4 PROJECT DESCRIPTION
Based on documents provided by the city (City of Cupertino, 2022), the plan for the park is the following. The ponds at the site are in the process of being removed. The City has also identified improvements required for the amphitheater. The Memorial Park Specific Plan will determine how to best meet the future recreation, community gathering, event, and green space needs of citizens through enhancement of the park, following the findings and recommendations of the City’s Parks and Recreation System Master Plan. The Master Plan’s vision for the park highlights expansion of the civic event space and community hub experiences by providing a unifying focus to the surrounding existing City facilities, and by enhancing natural site features. 5 SUBSURFACE EVALUATION AND LABORATORY TESTING
Our field exploration included a site reconnaissance and subsurface exploration of the project site. The subsurface exploration was conducted on August 24 and September 19, 2022 and consisted of seventeen ( 17) exploratory borings. The locations of the borings are presented on Figure 2. Prior to commencing the subsurface investigation, USA was notified for field marking of existing utilities and a private utility survey was conducted to further assess and locate any utilities that may conflict with the exploration locations.

The borings were advanced to depths of up to approximately 15 feet below the existing grade with a truck -mounted drill rig equipped with hollow -stem augers. A representative of Ninyo & Moore logged the subsurface conditions exposed in the borings and collected bulk and relatively undisturbed soil samples from the borings. The materials encountered in the borings were classified and logged in accordance with the Unified Soil Classification Syst em (USCS). The samples were then transported to our geotechnical laboratory for testing. The borings were backfilled with cement grout and capped off with soil cuttings in accordance with Santa Clara Valley Water District requirements. Detailed logs of the borings are presented in Appendix A.

Laboratory testing of soil samples recovered from the borings included in-situ soil moisture content and density, soil gradation, Atterberg limits, expansion index, R-value, and soil corrosivity.

The results of the in-place moisture content and dry density tests are shown on the boring logs in Appendix A. The results of the other laboratory tests, excluding the corrosivity testing, are -

presented in Appendix B. The results and findings of the corrosivity evaluation are provided in Appendix C.
6 GEOLOGIC AND SUBSURFACE CONDITIONS

6.1 Regional Geologic Setting
The site is located in the southwest ern portion of Santa Clara Valley, which is part of the Coast Ranges geomorphic province of California. The Coast Ranges are comprised of several mountain ranges and structural valleys formed by tectonic processes commonly found around the Circum- Pacific belt. Basement rocks have been sheared, faulted, metamorphosed, and uplifted, and are separated by thick blankets of Cretaceous and Cenozoic sediments that fill structural valleys and line continental margins. The San Francisco Bay Area has several mountain ranges that trend northwest, parallel to major strike-slip faults such as the San Andreas, Hayward, and Calaveras (Figure 3) . Major tectonic activity associated with these and other faults within this regional tectonic framework consists primarily of right-lateral, strike-slip movement.

6.2 Site Geology
A regional geologic map by Dibblee and Minch (2007) indicates that the site is un derlain by Holocene age surficial sediments. Dibblee and Minch describe this unit as alluvial sand, silt, and gravel deposited in the upper part of the alluvial fans formed along the foothills of the Santa Cruz Mountains. A map of the regional geology is presented as Figure 4.

6.3 Subsurface Conditions
The following section provides a generalized description of the materials encountered during our subsurface evaluation at the project site. More detailed descriptions are presented on the boring logs in Appendix A.

6.3.1 Alluvium
Alluvium was encountered in all of the borings to the depths explored. The alluvium encountered in the borings generally consisted of light brown to dark brown, dry to wet, loose to very dense, poorly graded gravel, well- graded gravel with clay and sand, clayey gravel, clayey sand; and dark brown to reddish brown, moist, very stiff to hard, lean clay and silty clay.

6.4 Groundwater
Groundwater was not encountered during our subsurface exploration. However, groundwater may rise to a higher level due to the relatively low seepage rate in clay and the limited time for observation. Fluctuations in the groundwater level may occur due to seasonal precipitation, variations in topography or subsurface hydrogeologic conditions, or as a result of changes to nearby irrigation practices or groundwater pumping. In addition, seeps may be encountered at elevations above the historic high groundwater levels due to perched groundwater conditions, leaking pipes, preferential drainage, or other factors not evident at the time of our exploration.

Regional studies by the California Geological Survey (CGS, 2002a) indicate that the depth to historic high groundwater is approximately 50 feet below the ground surface. 7 GEOTECHNICAL CONSIDERATIONS
This study considered a number of potential issues relevant to the proposed construction on the subject site, including seismic hazards, expansive soils, static settlement, excavation characteristics, and soil corrosivity. These issues are discussed in the following subsections.

7.1 Seismic Hazards
The seismic hazards considered in this study include the potential for ground rupture due to faulting, seismic ground shaking, liquefaction, and seismic slope stability. These potential hazards are discussed in the following subsections.

7.1.1 Historical Seismicity
The site is located in a seismically active region. Figure 3 presents the location of the site relative to the epicenters of historic earthquakes with magnitudes of 5.0 or more from 1800 to 2000. Records of historic ground effects related to seismic activity (e.g. liquefaction, sand boils, lateral spreading, ground cracking) compiled by Knudsen et al. (2000), indicate that ground effects related to historic seismic activity have not been reported for the site.

7.1.2 Faulting and Ground Surface Rupture
In response to hazards associated with ground rupture, or surface displacement, the State of California enacted the Alquist -Priolo Earthquake Fault Zoning Act (AP Act) in 1972, which regulates development of structures for human occupancy in areas within active fault zones.

The AP Act requires that the State Geologist delineate zones along active faults where evaluation of the potential for ground rupture is required. As defined by the California -
F-12 Memorial Park Specific Plan

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 5

Geological Survey (CGS, 2018), active faults are faults that have caused surface displacement within Holocene time, or within approximately the last 11,700 years.

The site is not located within an Alquist-Priolo Earthquake Fault Zone established by the State Geologist (CGS, 2018). The closest active fault and rupture hazard zone is the Monte Vista Shannon 2011 CFM located about 1.5 miles northwest of the site.

Based on our review of the referenced geologic maps, known active faults are not mapped on the site and the site is not located within a fault -rupture hazard zone. Therefore, the probability of damage from surface fault rupture is considered to be low.

7.1.3 Strong Ground Motion
Based on historic activity, the potential for future strong ground motion at the site is considered significant. Seismic design criteria to address ground shaking are provided in Section 9.1. The peak ground acceleration (PGA) associated with the Maximum Considered Earthquake Geometric Mean (MCE
G) was calculated in accordance with the American
Society of Civil Engineers (ASCE) 7 -16 Standard and the 2019 California Building Code (CBC). The MCE G peak ground acceleration with adjustment for site class effects (PGAM) was calculated as 1.018g using the USGS seismic design tool (SEAOCC & OSHPD, 2020) that yielded a mapped MCE G peak ground acceleration of 0.848g for the site and a site coefficient (FPGA) of 1.2 for Site Class D – Default and Risk Category II.

7.1.4 Liquefaction and Strain Softening
The site is not located within a liquefaction hazard zone (Figure 5) as established by the California Geological Survey (CGS, 2002b). In addition, regional studies of liquefaction susceptibility by the U.S. Geological Survey (Knudsen et al., 2000; and Witter et al., 2006) indicate that the site has a low susceptibility to liquefaction during a moderate to large magnitude earthquake on a nearby fault. Additionally, we did not encounter groundwater to the depths explored, which also indicates that the site has a low susceptibility to liquefaction.

As such, we do not regard seismically induced strain softening, liquefaction induced reduction in bearing capacity, sand- boil-induced ground subsidence, or lateral spreading as design considerations for the project.

Appendix F Geotechnical Evaluation F-13

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 6

7.1.5 Ground Subsidence
Sand boils that occur when liquefied, near -surface soil escapes to the ground surface, can result in ground subsidence due to a loss of material that is in addition to dynamic settlement.

We do not anticipate liquefaction at the site and as such, we do not anticipate sand boils and related ground subsidence at the site.

7.1.6 Lateral Spread
In addition to vertical displacements, seismic ground shaking can induce horizontal displacements as surficial soil deposits spread laterally by floating atop liquefied subsurface layers. Lateral spread can occur on sloping ground or on flat ground adjacent to an exposed face. The nearest exposed face slope is Stevens Creek, located approximately 1 mile from the western portion of the site. Based on the site location and our liquefaction analysis, we do not anticipate that lateral spreading will occur near the proposed improvements following a significant seismic event.

7.1.7 Seismic Slope Stability
The site and surrounding area are relatively flat and the site in not within a seismic hazard zone for earthquake-induced landslides as mapped by the state geologist (CGS, 2002b).

7.2 Expansive Soil
Some clay minerals undergo volume changes upon wetting or drying. Unsaturated soil containing those minerals will shrink/swell with the removal/addition of water. The heaving pressures associated with this expansion can damage structures and flatwork. Laboratory testing was performed on a sample of the near-surface soil to evaluate the expansion index. The tests were performed in accordance with American Society of Testing and Materials (ASTM) Standard D 4829 (Expansion Index). The results of our laboratory test indicate that the expansion indices of the samples tested were between 6 to 25 . These results are indicative of a very low to low expansion characteristic.

7.3 Static Settlement
Based on documents provided, we understand that the sustained loads for the proposed structures are expected to be relatively light. We anticipate, therefore, that the total static settlement of drilled pier foundations due to sustained loads will be less than ½ inch, provided the recommendations presented in this report are followed.

7.4 Excavation Characteristics
We anticipate that the proposed project will involve excavations of up to 15 feet in depth for installation of drilled pier foundations for light poles, shad structures, and play equipment. The soil encountered during our subsurface exploration over this interval generally consisted of firm to stiff clay and medium dense to dense sand and gravel with cobbles . We anticipate that heavy earthmoving equipment in good working condition should be able to make the proposed excavations. Near -vertical cuts or drilled shafts in these materials should not be consider ed stable. Recommendations for excavation stabilization are presented in Section 9.2.8. Excavations are not anticipated to extend below or near historic groundwater levels.

7.5 Corrosive/Deleterious Soil
Corrosivity analysis was performed by CERCO Analytical, Inc. of Concord, California on samples of the near-surface soil from boring B-6a. As reported by CERCO Analytical, the samples were determined to be corrosive based on resistivity test results. CERCO Analytical’s report (see Appendix C) included the following recommendation: “All buried iron, steel, cast iron, ductile iron, galvanized steel and dielectric coated steel or iron should be properly protected against corrosion depending upon the critical nature of the structure. All buried metallic pressure piping such as ductile iron firewater pipelines should be protected against corrosion.” Please refer to the CERCO Analytical report included in Appendix C for more information regarding their test results and brief evaluation.
8 CONCLUSIONS
Based on our review of the referenced background data, site reconnaissance, subsurface evaluation, and laboratory testing, it is our opinion that the proposed construction is feasible from a geotechnical standpoint. Geotechnical considerations include the following:
• The subsurface conditions encountered during our exploration generally consisted of light brown to dark brown, dry to wet, loose to very dense, poorly graded gravel, well-graded gravel with clay and sand, clayey gravel, clayey sand; and dark brown to reddish brown, moist, very stiff to hard, lean clay and silty clay.
• Groundwater was not encountered during our subsurface exploration . Variations in the groundwater level across the site and over time should be anticipated. Regional mapping indicates that the historic high groundwater level is approximately 50 feet below the existing grade.
• We anticipate that the proposed project will involve excavations of up to 15 feet below the existing grade for installation of drilled pier foundations. Stability of excavations will be a concern, particularly where excavation sidewalls are disturbed by construction operations, or -
Appendix F Geotechnical Evaluation F-15

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 8

where excavations encounter relatively cohesionless soil or are exposed to water.

Recommendations for excavation stabilization are provided. • Static settlement should be tolerable for the proposed improvements provided that the proposed structures are supported on foundations that conform with our recommendations and fill placement to raise grades is less than 2 feet in height. • Our laboratory test results indicate that the near-surface soil has a very low to low expansion characteristic.
• Based on the results of the soil corrosivity tests during this study, the soils are considered to be corrosive (Appendix C) to buried ferrous metals as is typical for the area. Buried metals, such as play equipment, should be properly protected against corrosion. Corrosion protection measures should be discussed with the equipment manufacturer and may include corrosion resistant paint or other coatings.
9 RECOMMENDATIONS
The following sections present our geotechnical recommendations for the design and construction of the proposed improvements. The project improvements should be designed and constructed in accordance with these recommendations, applicable codes, and appropriate construction practices.

9.2 Earthwork Recommendations
Earthwork should be performed in accordance with the requirements of applicable governing agencies and the recommendations presented below. The geotechnical consultant should observe foundation excavations and earthwork operations. Evaluations performed by the geotechnical consultant during the course of operations may result in new recommendations, which could supersede the recommendations in this section.

9.2.1 Pre-Construction Conference
We recommend that a pre-construction conference be held to discuss the recommendations presented in the report. Representatives of the District, the design engineer, Ninyo & Moore, and the contractor should be in attendance to discuss project schedule and earthwork requirements.

9.2.2 Site Preparation
Site preparation should begin with the removal of existing vegetation, utility lines, debris and other deleterious materials from areas to be graded. Tree stumps and roots should be removed to such a depth that organic material is generally not present. Clearing and grubbing should extend beyond the proposed excavation and fill areas. Rubble and excavated materials that do not meet criteria for use as fill should be disposed of in an appropriate landfill. Existing utilities in the work area should be relocated away from the proposed structures. Existing utilities to be abandoned should be removed, crushed in place, or backfilled with grout.

Appendix F Geotechnical Evaluation F-17

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 10

Excavations resulting from removal of buried utilities, tree stumps, or obstructions should be backfilled with compacted fill in accordance with the recommendations in the following sections.

9.2.3 Observation and Removals
Prior to placement of fill, or the placement of forms or reinforcement for foundations, the client should request an evaluation of the exposed subgrade by Ninyo & Moore. Materials that are considered unsuitable shall be excavated under the observation of Ninyo & Moore in accordance with the recommendations in this section or supplemental recommendations by the geotechnical engineer.

Unsuitable materials include, but may not be limited to dry, loose, soft, wet, expansive, organic, or compressible natural soil, and undocumented or otherwise deleterious fill materials. Unsuitable materials should be removed from trench bottoms and below bearing surfaces to a depth at which suitable foundation subgrade is exposed, as evaluated in the field by Ninyo & Moore.

9.2.4 Material Recommendations
Materials used during earthwork, grading, and paving operations should comply with the requirements listed in Table 2. Materials should be evaluated by the geotechnical engineer for suitability prior to use. The contractor should notify the geotechnical consultant prior to import of materials or use of on -site materials to permit time for sampling, testing, and evaluation of the proposed materials. On-site materials may need to be dried out before re- use as fill. The contractor should be responsible for the uniformity of import material brought to the site.

9.2.7 Temporary Excavations and Shoring
Trench excavations shall be stabilized in accordance with the Excavation Rules and Regulations (29 Code of Federal Regulations [CFR], Part 1926) stipulated by the Occupational Safety and Health Administration (OSHA). Stabilization shall consist of shoring sidewalls or laying slopes back.

Dewatering pits or sumps should be used to depress the groundwater level (if encountered) below the bottom of the excavation. Table 5 lists the OSHA material type classifications and corresponding allowable temporary slope layback inclinations for soil deposits that may be encountered on site. We encountered granular soils that consisted of loose to very dense, silty sand during our subsurface investigation, which corresponds to OSHA Type C soil. If materials other than those anticipated are encountered, Ninyo & Moore should be provided an opportunity to review subsurface conditions. Alternatively, an internally -braced shoring system or trench shield conforming to the OSHA Excavation Rules and Regulations (29 CFR, Part 1926) may be used to stabilize excavation sidewalls during construction. The lateral earth pressures listed in Table 6 may be used to design or select the internally-braced shoring system or trench shield. The recommendations listed in Table 6 are based upon the limited subsurface data provided by our subsurface exploration and reflect the influence of the environmental conditions that existed at the time of our exploration. Excavation stability, material classifications, allowable slopes, and shoring pressures should be re-evaluated and revised, as-needed, during construction. Excavations, shoring systems and the surrounding areas should be evaluated daily by a competent person for indications of possible instability or collapse.

Appendix F Geotechnical Evaluation F-21

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 14

The shoring system should be designed or selected by a suitably qualified individual or specialty subcontractor. The shoring parameters presented in this report are preliminary design criteria, and the designer should evaluate the adequacy of these parameters and make appropriate modifications for their design. We recommend that the contractor take appropriate measures to protect workers. OSHA requirements pertaining to worker safety should be observed.

Excavations made in close proximity to existing structures may undermine the foundation of those structures and/or cause soil movement related distress to the existing structures.

Stabilization techniques for excavations in close proximity to existing structures will need to account for the addit ional loads imposed on the shoring system and appropriate setback distances for temporary slopes. The contractor should be solely responsible for protection of existing site improvements and provide shoring and/or underpinning as needed.

The excavation bottoms may encounter wet, loose material which may be subject to pumping under heavy equipment loads. The contractor should be prepared to stabilize the bottom of the excavations. In general, unstable bottom conditions may be mitigated by using a stabilizing geogrid, overexcavating the excavation bottom to suitable depths and replacing with compacted fill, or other suitable method. Additionally, aeration of wet soils should be anticipated.

9.2.8 Utility Trenches
Trenches constructed for the installation of underground utilities should be stabilized in accordance with our recommendations in Section 9.2.9. Utility trenches should be backfilled with materials that conform to our recommendations in Section 9.2.5. Trench backfill, bedding, and pipe zone fill should be compacted in accordance with Section 9.2.7 of this report. Bedding and pipe zone fill should be shoveled under pipe haunches and c ompacted by manual or mechanical, hand- held tampers. Trench backfill should be compacted by mechanical means. Densification of trench backfill by flooding or jetting should not be permitted.

Trenches should not be excavated adjacent to footings. If trenches are to be excavated near a continuous footing, the bottom of the trench should be located above a 2:1 (horizontal to vertical) plane projected downward from the bottom of the footing. Utility lines that cross beneath footings should be encased in concrete or CLSM below the footing for a distance equivalent to the depth of the excavation.

9.3 Foundations
Foundations should be designed in accordance with structural considerations and our geotechnical recommendations. In addition, requirements of the governing jurisdictions, practices of the Structural Engineers Association of California, and applicable building codes should be considered in the design of the structures. Maximum static settlement due to building loads is anticipated to be on the order of ½ inch.

9.3.1 Spread Footings
Footings bearing on subgrade prepared as per the recommendations in Section 9.2.6 . The footings may be designed using the criteria listed in Table 6 . The geotechnical engineer should observe the footing excavations to evaluate bearing materials and subgrade condition before the exposed subgrade is covered.

Structures supported on footings consistent with these recommendations should be designed for the total and differential settlements listed in Table 6 for sustained loads.

The spread footings should be reinforced with deformed steel bars as detailed by the project structural engineer. Where footings are located adjacent to utility trenches or other excavations, the footing bearing surfaces should bear below an imaginary plane extending upward from the bottom edge of the adjacent trench/excavation at a 1½:1 (horizontal to vertical) angle above the bottom edge of the footing. Footings should be deepened or excavation depths reduced as-needed. Footing bottoms should not be sloped more than 1- unit vertical to 10 units horizontal. Wall footings may be stepped provided that the bearing grade differential between adjacent steps does not exceed 18 inches and the slope of a series of such steps does not exceed 1-unit vertical to 2 units horizontal. -
Appendix F Geotechnical Evaluation F-23

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 16

A lateral bearing pressure of 300 psf per foot of depth up to 3,000 psf may be used to evaluate the resistance of footings to lateral loads. The recommended lateral bearing pressure is for level and gently sloping ground conditions where the ground slope adjacent to the foundation is 5 percent or less. The lateral bearing pressure should be neglected to a depth of 12 inches where the ground adjacent to the foundation is not covered by a slab or pavement. The lateral bearing pressure may be increased by one- third when considering loads of short duration such as wind or seismic forces. A friction coefficient of 0.35 may be assumed for evaluating frictional resistance to lateral loads. A dry unit weight of 90 pounds per cubic foot (pcf) for soil, 120 pcf for aggregate and 150 pcf for normal weight concrete may be assumed for this evaluation.

9.3.2 Slabs-on-Grade
Building floor slabs should be designed by the project structural engineer based on the anticipated loading conditions. The subgrade should be prepared in accordance with Section

9.2.6. Where a vapor retarding system is not used, slabs should be constructed on 6 inches, or more, of aggregate base conforming to Section 9.2.5 and placed in accordance with Section 9.2.7. The slab should be reinforced with deformed steel bars. We recommend that masonry briquettes or plastic chairs be used to aid in the correct placement of slab reinforcement in the upper half of the slab. Refer to Section 9.5 for the recommended concrete cover over reinforcing steel. A vapor retarder is recommended in areas where moisture-sensitive floor coverings or conditioned environments are anticipated. Joints consistent with ACI guidelines (ACI, 2020) may be constructed at periodic intervals to reduce the potential for random cracking of the slab.

9.3.3 Drilled Piers for Minor Structures
Drilled piers for minor structures such as fences and light poles embedded 5 to 25 feet below grade may be designed for an allowable side friction of 300 psf to evaluate resistance to downward axial loads and 200 psf per foot depth for upward axial loads. The allowable skin friction includes a factor of safety of 2 for downward loading and 3 for upward loading. The allowable side friction may be increased by one-third when considering loads of short duration such as wind or seismic loads. The spacing between adjacent piers should be equivalent to eight pier diameters, or more to mitigate reduction due to group effects.

A lateral bearing pressure of 300 pounds per square foot (psf) per foot depth up to 3,000 psf may be used to evaluate resistance to lateral loads and overturning moments in accordance with Section 1806 of the 2019 CBC. The allowable lateral bearing pressure may be increased -
F-24 Memorial Park Specific Plan

Ninyo & Moore | 21121 Stevens Creek Boulevard, Cupertino, California | 404269001 | November 3, 2022 17

by one-third for wind or seismic load combinations and by an additional factor of two for structures that can accommodate ½ inch of lateral deflection of the top of the pier foundation.

Drilled pier excavations should be cleaned of loose material prior to pouring concrete. Drilled pier excavations that encounter groundwater or cohesionless soil may be unstable and may need to be stabilized by temporary casing or use of drilling mud. Standing water should be removed from the pier exc avation or the concrete should be delivered to the bottom of the excavation, below the water surface, by tremie pipe. Casing should be removed from the excavation as the concrete is placed. Concrete should be placed in the piers in a manner that reduces the potential for segregation of the components. Piers should be completed with concrete the same day as the excavation is completed.

9.4 Pavements and Flatwork
Recommendations for pavement and exterior flatwork are presented in the following sections. A design R-value of 20 was selected based on subsurface soil encountered . The pavement subgrade should be observed by the geotechnical engineer during grading to check the finish subgrade for consistency with the assumed condition. Recommendations for preparation of subgrade are presented in Section 9.2.6.

9.4.1 Asphalt Pavement
Based on the damage observed along the pedestrian pathways, we recommend complete removal of the existing pavement sections and reconstruction with a new section of aggregate base and asphalt concrete. The existing aggregate base and asphalt concrete may be processed to meet Caltrans Class 2 Aggregate Base specifications for re-use.

Ninyo & Moore conducted an analysis to evaluate appropriate asphalt pavement structural sections following the methodology presented in the Highway Design Manual (Caltrans, 2020). Alternative sections were evaluated for pedestrian and vehicular loading. The pavement sections were designed for a 20 -year service life presuming that periodic maintenance, including crack sealing and resurfacing will be performed during the service life of the pavement. Premature deterioration may occur without periodic maintenance. Our recommendations for the pavement sections are presented in Table 7. -

Table 7– Asphalt Concrete Pavement Sections
Traffic Index R-Value Alternative 1 Alternative 2
3 (Light Vehicular Traffic) 20 3½ inches AC 2 inches AC 4½ inches AB
6 (Fire Lanes) 20 8 inches AC 3½ inches AC
9½ inches AB
Notes:
1 AC is Type A, Dense-Graded Hot Mix Asphalt complying with Caltrans Standard Specification 39-2 (2018). 2 AB is Class 2 Aggregate Base complying with Caltrans Standard Specification 26-1.02 (2018).

Aggregate base for pavement should be placed in lifts of no more than 8 inches in loose thickness and compacted per Section 9.2.7. Asphalt concrete should be placed and compacted in accordance with Caltrans Standard Specification and Construction Manual; asphalt concrete should be compacted to between 92 and 96 percent of the theoretical maximum specific gravity and density (Rice gravity – ASTM D 2041) of the material.

Pavements should be sloped so that runoff is diverted to an appropriate collector (concrete gutter, swale, or area drain) to reduce the potential for ponding of water on the pavement.

Concentration of runoff over asphalt pavement should be discouraged.

9.5 Concrete Placement
Concrete in contact with soil or water that contains high concentrations of soluble sulfates can be subject to chemical and/or physical deterioration. The sulfate ion concentration was measured 49 mg/kg and is determined to be insufficient to damage reinforced concrete structures, however due to the potential variability in soil conditions across the site, we recommend that Type V cement with a water/cement ratio of 0.45 or less be considered for the project.

9.6 Review of Construction Plans
The recommendations provided in this report are based on preliminary design information for the proposed construction. We recommend that a copy of the plans be provided to Ninyo & Moore for review before bidding to check the interpretation of our recommendations and that the designed improvements are consistent with our assumptions. It should be noted that, upon review of these documents, some recommendations presented in this report might be revised or modified to meet the project requirements.

9.7 Construction Observation and Testing
The recommendations provided in this report are based on subsurface conditions encountered in discrete exploratory borings. During construction, the geotechnical engineer or his representative in the field should be allowed to check the exposed subsurface conditions. During construction, the geotechnical engineer or his representative should be allowed to:
• Check for unsuitable materials and observe foundation excavations. • Observe preparation and compaction of subgrade.
• Check and test imported materials prior to import to the project site. • Observe placement and compaction of fill.
• Perform field density tests to evaluate fill and subgrade compaction. • Observe placement of reinforcing steel and concrete in drilled piers and slabs.

The recommendations provided in this report assume that Ninyo & Moore will be retained as the geotechnical consultant during the const ruction phase of the project. If another geotechnical consultant is selected, we request that the selected consultant provide a letter to the architect and the owner (with a copy to Ninyo & Moore) indicating that they fully understand Ninyo & Moore’s recommendations, and that they are in full agreement with the recommendations contained in this report. Ninyo & Moore cannot assume responsibility for aspects of construction for which we have not been given an opportunity to observe/test.
10 LIMITATIONS

BORING LOGS
Field Procedure for the Collection of Disturbed Samples Disturbed soil samples were obtained in the field using the following method.

Bulk Samples
Bulk samples of representative earth materials were obtained from the exploratory borings. The samples were bagged and transported to the laboratory for testing.

Field Procedure for the Collection of Relatively Undisturbed Samples Relatively undisturbed soil samples were obtained in the field using the following method.

The Modified Split-Barrel Drive Sampler
The sampler, with an external diameter of 3.0 inches, was lined with 6-inch long, thin brass liners with inside diameters of approximately 2.4 inches. The sample barrel was driven into the ground with the weight of a hammer in general accordance with ASTM D 3550. The driving weight was permitted to fall freely. The approximate length of the fall, the weight of the hammer, and the number of blows per foot of driving are presented on the boring log as an index to the relative resistance of the materials sampled. The samples were removed from the sample barrel in the brass liners, sealed, and transported to the laboratory for testing.

APPENDIX B

LABORATORY TESTING
Classification
Soils were visually and texturally classified in accordance with the Unified Soil Classification System (USCS) in accordance with ASTM D 2488. Soil classifications are indicated on the logs of the exploratory borings in Appendix A.

In-Place Moisture and Density
The moisture content and dry density of relatively undisturbed samples obtained from the exploratory borings were evaluated in accordance with ASTM D 2937. The test results are presented on the logs of the exploratory borings in Appendix A.

Gradation Analysis
Gradation analysis tests were performed on selected representative soil samples in accordance with ASTM D 422. The grain-size distribution curves are shown on Figures B-1 through B-4. These test results were utilized in evaluating the soil classifications in accordance with the USCS.

Atterberg Limits
Tests were performed on selected representative fine-grained soil samples to evaluate the liquid limit, plastic limit, and plasticity index in accordance with ASTM D 4318. These test results were utilized to evaluate the soil classification in accordance with the USCS. The test results and classifications are shown on Figure B-5.

Expansion Index
The expansion index of a selected material was evaluated in accordance with ASTM D 4829. The specimen was molded under a specified compactive energy at approximately 50 percent saturation (plus or minus 1 percent). The prepared 1 inch thick by 4 inch diameter specimen was loaded with a surcharge of 144 pounds per square foot and inundated with tap water. Readings of volumetric swell were made for a period of 24 hours. The test results are presented on Figure B-6.

Project Name: Memorial Park, 21121 Stevens Creek Blvd., Cupertino, CA Corrosivity Analysis - ASTM Test Methods
Dear Ms. Gospe:

Pursuant to your request, CERCO Analytical has analyzed the soil sample submitted on August 29, 2022.

Based on the analytical results, this brief corrosivity evaluation is enclosed for your consideration.

Based upon the resistivity measurement, this sample is classified as "corrosive". All buried iron, steel, cast iron, ductile iron, galvanized steel and dielectric coated steel or iron should be properly protected against corrosion depending upon the critical nature of the structure. All buried metallic pressure piping such as ductile iron firewater pipelines should be protected against corrosion.

The chloride ion concentration is 78 mg/kg and is determined to be insufficient to attack steel embedded in a concrete mo1iar coating.

The sulfate ion concentration is 49 mg/kg and is determined to be insufficient to damage reinforced concrete structures and cement mortar-coated steel at this location.

The pH of the soil is 7.32, which docs not present corrosion problems for buried iron, steel, mortar-coated steel and reinforced concrete structures.

The red ox potential is 200-m V and is indicative of potentially "moderately corrosive" soils resulting from anaerobic soil conditions.

This corrosivity evaluation is based on general corrosion engineering standards and is non-specific in nature. For specific long-term corrosion control design recommendations or consultation, please call JDH Corrosion Consultants, Inc. at (925) 927-6630.

We appreciate the oppottunity of working with you on this project. If you have any questions, or if you require fmther information, please do not hesitate to contact us.

Very truly yours,
CERCO ANALYTICAL, INC.

Planning Context
The Memorial Park Specific Plan is a forward-looking
document that aims to preserve the current character
of the park while also providing new active and
passive recreational opportunities for residents and
visitors. Multiple City-wide planning efforts apply
to Memorial Park and have guided its vision to be a
place that embraces Cupertino’s diverse community.

City of Cupertino General Plan (2014)
The City adopted the 2015-2040 General Plan in
2014 with the aspiration to have a vibrant, mixed-
use “Heart of the City” with exemplary parks
and accessible open space areas. The General Plan
presents the City’s vision to be safe, friendly, healthy, connected, walkable, bike-able, and inclusive for all
residents and workers.

The General Plan follows 12 guiding principles to
attain Cupertino’s desired future.
•
Dev
elop cohesive neighborhoods: Ensure that
all neighborhoods are safe, attractive and include
convenient pedestrian and bicycle access to a “full-
service” of local amenities such as parks, schools,
community activity centers, trails, bicycle paths ,
and shopping.
•
Improv
e public health and safety: Promote public
health by increasing community-wide access to
healthy foods; ensure an adequate amount of
safe, well-designed parks, open space, trails, and
pathways; and improve safety by ensuring all
areas of the community are protected from natural
hazards and fully served by disaster planning
and neighborhood watch programs, police, fire,
paramedic, and health services.
•
Improv
e connectivity: Create a well-connected
and safe system of trails, pedestrian and bicycle
paths, sidewalks and streets with traffic calming
measures that weave the community together,
enhance neighborhood pride and identity, and
create access to interesting routes to different
destinations.
•
Enhance mobility:

Ensure the efficient and safe
movement of cars, trucks, transit, pedestrians,
bicyclists, and disabled persons throughout
Cupertino in order to fully accommodate
Cupertino’s residents, workers, visitors and
students of all ages and abilities. Streets, pedestrian paths, and bike paths should comprise an integrated
system of fully connected and interesting routes to
all destinations.
-
G-4 Memorial Park Specific Plan
•
Ensure
a balanced community: Offer residents
a full range of housing choices necessary
to accommodate the changing needs of a
demographically and economically diverse
population, while also providing a full range
of support uses including regional and local
shopping, education, employment, entertainment,
recreation, and daily needs that are within easy
walking distance.
•
Support vib
rant and mixed-use businesses:

Ensure that Cupertino’s major mixed-use corridors
and commercial nodes are vibrant, successful,
attractive, friendly, and comfortable with inviting
active pedestrian spaces and services that meet the
daily needs of residents and workers.
•
Ensure
attractive community design: Ensure
that buildings, landscapes, streets and parks are
attractively designed and well maintained so they
can complement the overall community fabric by
framing streets and offering a variety of active,
relaxing and intimate pedestrian spaces.
•
Embrace div
ersity: Celebrate Cupertino’s diversity
by offering a range of housing, shopping and
community programs that meet the needs of the
full spectrum of the community, while ensuring
equal opportunities for all residents and workers
regardless of age, cultural or physical differences.
•
Support
education: Preserve and support quality
community education by partnering with local
school districts, community colleges, libraries,
and other organizations to improve facilities
and programs that enhance learning and expand
community- wide access.
•
Preserv
e the environment: Preserve Cupertino’s
environment by enhancing or restoring creeks
and hillsides to their natural state, limiting urban
uses to existing urbanized areas, encouraging
environmental protection, promoting sustainable
design concepts, improving sustainable municipal
operations, adapting to climate change, conserving
energy resources, and minimizing waste.
•
Ensure
fiscal self-reliance: Maintain fiscal self-
reliance in order to protect the City’ s ability to
deliver essential, high-quality municipal services
and facilities to the community.
•
Ensure a responsiv
e government: Continue to
be a regional leader in accessible and transparent
municipal government; promote community
leadership and local partnerships with local
and regional agencies; and remain flexible and
responsive to changing community needs.

Memorial Park follows several of these principles
and supports the City’s mission in providing a safe
and inclusive space that is diverse, attractive, and
pedestrian friendly. The Land Use (LU), Mobility
(M), Environmental Resources and Sustainability
(ES), and Recreation, Parks, and Community Services
(RPC) Elements of the General Plan outline goals,
policies, and actions to guide the City of Cupertino in future park-related projects.

The General Plan called for a Parks and Recreation
System Master Plan, which was subsequently
adopted in 2020 and provides recommendations
specific to Memorial Park. The General Plan also
recommended pedestrian and bicycle improvements
on Stelling Road in order to enhance connections to
the park.

Appendix C Planning Context G-5
Heart of the City Specific Plan (2014)
The Heart of the City Specific Plan acts as a guide
for future development and redevelopment projects
along Stevens Creek Boulevard to ensure Cupertino
embodies a greater sense of place and community
identity. The Specific Plan covers approximately 635
acres along 2.5 miles of Stevens Creek Boulevard,
including Memorial Park.

Being one of the most important corridors and streets
within the city, the goal of this plan is to develop a
collection of pedestrian-inclusive gathering spaces
along the boulevard that bring a sense of place and
community to residents and visitors alike. Included
in this plan are guidelines on streetscape, design
and development standards, design concepts,
related zoning ordinances, infrastructure and
implementation plans, and estimated costs of the
project.

Memorial Park falls into the West Stevens Creek
Boulevard area, of which the primary use is quasi-
public and public facilities that support mixed
commercial and residential uses. The planting theme
in this area is “Oak Grove.” It features an informal
arrangement of Live Oaks (Quercus agrifolia ) and
native wildflowers in curbside planting strips along
the frontage of Stevens Creek Boulevard.

Memorial Park and its immediate area are zoned
under the Heart of the City Specific Plan. The park
is a Park and Recreation (PR) zone and is mostly
surrounded by residential uses.

The park is adjacent to Multi-Family Residential (R-3)
zones to the west and Single-Family Residential (R-1)
zones to the north and northeast. To the far northeast
of the park is a Quasi-Public Building (BQ) zone that
contains a day care and child development center.

The neighborhood directly south of the Quinlan
Community Center is a Planned Development (P)
zone for residential uses only, which consists of
condominiums and townhouses. There are two
nearby Planned Development (P) zones that allow
for General Commercial (CG) and residential uses—
one of which is directly east of the Cupertino Sports
Center while the other is on the opposite site of Mary
Avenue along the southwest corner of the park. A
large Public Building (BA) zone borders the southern
edge of the park, which contains De Anza College
and Faria Elementary School.

G-6 Memorial Park Specific Plan
ADA Self-Evaluation and Transition Plan
(2015)
The ADA Self-Evaluation and Transition Plan
identifies policy, program, and physical barriers
to accessibility to help develop barrier removal
solutions that improve access for all individuals. This self-evaluation report is an assessment of the City’s
current policies, practices, and procedures in relation to the American with Disabilities Act (ADA). The
report goes into further detail of each department’s
current accessibility and additional recommendations
to improve user experiences. A transition plan
then outlines a strategy to transition inaccessible
facilities into environments that are accessible to and functional for individuals with disabilities.

In terms of parks and recreation, it was recommended
to adjust policies relating to allowing service animals, regardless of disability, to be acceptable in all parks and City buildings. The plan also recommends
that more meetings and public events to be made
accessible in American Sign Language (ASL).

Additionally, recreation and community services
should provide accommodations for people upon
request, training for staff addressing services for
people with disabilities, transportation services for
camps and the Cupertino Senior Center, and more.

Bicycle Transportation Plan (2016)
The City adopted the Bicycle Transportation Plan in
2016 that identifies a prioritized list of projects that support and promote bicycling in Cupertino. The
vision statement of the plan is “the City of Cupertino
envisions an exceptional bicycling environment that
supports active living and healthy transportation
choices, provides for safer bicycling, and enables
people of all ages and abilities to access jobs, schools, recreation, shopping, and transit on a bicycle as a
part of daily life.” The plan has three stated goals:
•
Goal 1:

Increase awareness and value of bicycling
through encouragement, education, enforcement,
and evaluation programs.
•
Goal 2:

Improve bicyclist safety through the design
and maintenance of roadway improvements.
•
Goal 3:

Increase and improve bicycle access
to community destinations across the City of
Cupertino for all ages and abilities.

The plan recommends improvements to the extensive
bicycle network that will establish safe connections
to key destinations. The proposed bikeway projects
include bike paths, separated and buffered lanes,
boulevards, routes, and spot improvements.

The plan proposes multiple projects that relate to
Memorial Park, such as a Class IV separated bikeway
along both sides of North Stelling Road and Stevens
Creek Boulevard. The plan also proposed a Class
II buffered bike lane along Mary Avenue, which is
now complete, and a bike route through the park
that would connect Alves Drive to Mary Avenue as
part of a larger Class III bike route project. Lastly, the plan recommended spot improvements for safety in
the southeast corner of Quinlan Community Center
at the intersection of Alves Drive and North Stelling
Avenue.
-
Appendix C Planning Context G-7
Pedestrian Transportation Plan (2018)
The City adopted the Pedestrian Transportation Plan
in 2018 with the goal to create an inviting and safe
walkable environment that promotes active living and
healthy transportation choices, enhances the quality
of life for all community members and visitors, and
creates a seamless and integral connected, multi-
modal transportation network. The plan recommends
an integrated network of walking paths that provide
a wide range of access to various nodes of activity,
including parks. The following goals inspired the
recommendations and implementation strategy
incorporated into this plan:
•
Goal 1: Safety
– Improve pedestrian safety and
reduce the number and severity of pedestrian-
related collisions, injuries, and fatalities.
•
Goal
2: Access – Increase and improve pedestrian
access to community destinations across the City
of Cupertino for people of all ages and abilities.
•
Goal 3: Connectivity
– Continue to develop a
connected pedestrian network that fosters an
enjoyable walking experience.

The plan recommends a sidewalk buffer from the
State Route 85 northbound on-ramp to North Stelling
Road, which covers the park’s southern frontage. The
plan also recommends a shared-use path and bike/
pedestrian bridge over State Route 85 that would
improve pedestrian access to the park from the
west. Additional recommendations include adjusted
median curblines to provide a clear, accessible path
of travel for pedestrians across the intersection of
Stevens Creek Boulevard and Mary Avenue, as well
as a new high-visibility crosswalk on the west leg
of this intersection. Lastly, the plan identifies the
intersection of North Stelling Road and Alves Drive,
at the southeast corner of Quinlan Community
Center, as a priority project location for pedestrian
improvements. At the time of this document, these
recommendations and improvements have not been
realized.

Green Stormwater Infrastructure Plan (2019)
In 2019, the City produced and adopted a Green
Stormwater Infrastructure Plan (GSI) to commit to a
sustainable drainage system that is environmentally
efficient. The GSI guides the City in the identification, implementation, tracking, and reporting of green
stormwater infrastructure projects within its
jurisdiction and coordinated with the General Plan,
the Climate Action Plan, the Bicycle Transportation
Plan, the Pedestrian Transportation Plan, and other
specific and master plans to provide a pleasant urban
environment for residents, workers, and visitors.

Specific goals of the GSI are:
•
Goal 1:

Align the City’s goals, policies, and
implementation strategies for GSI with the General
Plan and other related planning documents
•
Goal 2:

Identify and prioritize GSI opportunities
throughout the City
•
Goal 3:

Establish targets for the extent of City area
to be addressed by GSI over certain timeframes
•
Goal 4:

Provide a workplan and legal and funding
mechanisms to implement prioritized projects
•
Goal 5:

Establish a process for tracking, mapping,
and reporting completed projects
The GSI identifies green stormwater infrastructure
opportunities on public parcels and street segments.

The GSI generally recommends that all parks
incorporate green stormwater infrastructure with
enhanced educational signage explaining the
function and purpose of the improvements. Nearby
portions of Stevens Creek Boulevard, Mary Avenue,
and North Stelling Road are designated as a street
segments with green stormwater infrastructure
opportunity.

Memorial Park was specifically identified as an
opportunity site to construct an infiltration basin to
treat runoff from Stevens Creek Boulevard.

G-8 Memorial Park Specific Plan
Parks and Recreation System Master Plan
(2020)
On February 18, 2020, the City adopted the Parks
and Recreation System Master Plan. This plan
provides a cohesive vision and strategy to guide
future development, renovation, management, and
programming of the City’s parks and recreation
facilities through the year 2040.

Between 2015 and 2018, more than an estimated 2,000
community members provided input and feedback
on the Master Plan. Various online and in-person
activities were held to invite residents, stakeholders, partners, businesses, elected officials, staff, youth,
and people of diverse cultural backgrounds to share
their aspirations for the parks and recreation system.

The planning process identified broad community
support to preserve and enhance recreation,
walkability, access to open spaces, and Cupertino’s
sense of place and quality of life.

The community preferences, priorities, and
expectations revealed 12 themes:
•
P

Appendix C Planning Context G-9
The Parks and Recreation System Master Plan has
seven goals:
•
MP1.

Conservation: Protect nature, trees and
natural areas in parks and throughout the city
to support wildlife, ecological functions and
a stronger connection to Cupertino’s natural
environment.
•
MP2. Connection: Provide
an interconnected
network of multiuse trails, walkways and
bikeways, close-to-home parks, and community
destinations.
•
MP3.

Equitable Access: Distribute parks and
facilities throughout the community for easy and
equitable access.
•
MP4.

Enhancement: Reinvigorate and revitalize
parks and recreation facilities to support broad
and inclusive recreation interests.
•
MP5.

Activity: Provide programs, events and
services that foster social cohesiveness and lively,
diverse activities for people of all ages, abilities,
cultures, and interests.
•
MP6. Quality:

Create high quality recreation
experiences, places and services that are
welcoming, safe, responsive, comfortable and
reflective of Cupertino’s unique character.
•
MP7. Sustainability:

Provide, manage and
maintain parks, facilities, programs and services
through sound management and stewardship,
sustainable choices and the wise use of resources.

Memorial Park was identified as an ideal location for
several general improvements proposed in the plan,
including expanded senior services as well as nature
play and all-inclusive play opportunities.

There are specific recommendations in the Parks and
Recreation System Master Plan for Memorial Park.

Recommendations include improvements to facilities
and infrastructure to accommodate community-
wide civic or social events and festivals, additional
recreation space for older adults, maintaining the
lighted softball field, repurposing the inactive ponds, developing at least two dual-striped pickleball
courts, and enhancing natural vegetation. Actions
identified for the short term were improvements
specifically to the ponds and amphitheater, as well
as the enhancement of pathways, seating, shade,
and accessibility elements. The overall vision for
Memorial Park included an expansion of the civic
event space and enhancement of the natural site
features, as well as a focus on integrating the park
with the surrounding City facilities.

The Parks and Recreation System Master Plan called
for a site master plan and initial site improvements
for Memorial Park as an immediate opportunity that
supports the Enhancement, Activity, and Quality
goals. The Memorial Park Specific Plan fulfills this
recommendation.

Parks and Recreation System Master Plan Vision
“We aspire to create an inspiring, lively, healthy, diverse and sustainable community by connecting our residents
to outstanding parks, nature and one another.”

G-10 Memorial Park Specific Plan
Climate Action Plan (2022)
The Climate Action Plan 2.0 (CAP) updated the
previous 2015 CAP. The CAP 2.0 intends to improve
the wellbeing of the community by developing a
summary of existing and projected greenhouse gas
(GHG) emission levels, establishing GHG emissions
targets, and committing to GHG reduction and
climate adaptation measures. The guiding principles
of the CAP 2.0 are equity, innovation, urgency and
flexibility, and resilience and adaptation.

The City’s goal is to achieve carbon neutrality by
2040. The climate adaptation measures presented
in the CAP 2.0 are a suite of actions to achieve
this goal which were designed in consideration of
partnerships, equity, financing, structural change,
and engagement. In addition to reducing GHG
emissions, the climate adaptation measures are
intended to help the City adapt to impacts of climate
change that may be unavoidable.

Specific actions in the CAP 2.0 are studying
opportunities for carbon sequestration, providing
ecologically-responsible recreation opportunities
in parks, and improving public transit and micro-
mobility infrastructure while reducing vehicle
parking where feasible.

H-4 Memorial Park Specific Plan
Existing Amenities
Memorial Park is a heavily utilized and amenitized
park (Figure H-1). There are two community facilities
at opposite ends of the site, an amphitheater, picnic
areas, multi-use lawn spaces, playgrounds, a softball
field, tennis courts, and other amenities to support
the function of the park.

Quinlan Community Center
The Quinlan Community Center is a 27,000-square-
foot recreation facility located in the southeastern
portion of Memorial Park. The Quinlan Community
Center, opened in 1990, is home to the City’s Parks
and Recreation Department and the Cupertino
Historical Society and Museum. The facility is named
after Robert W. Quinlan, Cupertino’s second City
Manager who served from 1971 to 1989. The building
is multi-use, offering classrooms and a variety of
other rooms available to rent for business or personal
needs. This includes a banquet room, known as the
Cupertino Room, that features a full catering kitchen
and attached patio that can accommodate over 200
guests. The Quinlan Community Center also hosts
classes for preschool, crafting, and dance and has a
small shaded play area attached to a rentable room in
the northern wing.

The Quinlan Community Center hosts the annual
Community Tree Lighting in December. This
indoor/outdoor event utilizes the building’s lobby,
courtyard, and adjacent event lawn for local choir
performances, a food pantry collection, photos with
Santa, craft tables, and the lighting ceremony.

The Quinlan courtyard on the western side of the
building was dedicated on August 17, 2010. It features
a small shade structure that is bracketed by the
wings of the building. The Quinlan event lawn lies
immediately west of the courtyard. The courtyard
is well-connected with the park’s pathway network,
with walkways from both the north and south ends
of the courtyard wrapping around the Quinlan event
lawn leading into the park. The lobby can be accessed
from both the western and eastern entrances and is
open from 8:00 am to 5:00 pm on weekdays.

Appendix H Site Assessment H-5
Cupertino Senior Center
The Cupertino Senior Center, a membership-based
recreation facility, is a 15,500-square-foot building
located in the southern portion of Memorial Park
along Stevens Creek Boulevard. It was originally
built in the early 1980s but was replaced around the
year 2000. The Cupertino Senior Center strives to
provide a welcoming and friendly environment for
adults over 50 years old, promoting a healthy lifestyle through quality education, recreation, travel, social,
and volunteer opportunities.

The main entrance to the building is on the north side, served by a parking lot accessed via Mary Avenue.

The main entrance features a memorial bench
and low seat wall with engraved tile dedications
bordering a paved plaza with shaded circular picnic
tables and a decorative pergola. There is a small deck
facing the park on the east side of the building that is undersized for its current usage.

The Cupertino Senior Center is not well connected to
Memorial Park in terms of pedestrian circulation and
programmed uses. There is a grade change from the
back of the building into the park that does not have
an accessible or direct pedestrian connection to the
existing internal pathway network.

Amphitheater
Memorial Park is home to the only public
amphitheater in Cupertino. It hosts the Summer
Concert Series and Shakespeare in the Park,
which both run during the summer months. The
amphitheater is highly valued by the community.

Terraced concrete seat walls are built into a small
hillside area to provide formal seating. The seat walls are surrounded by lawn and are backed by a grove
of trees. There are no ramps, stairs, or handrails and
therefore limited accessibility.

The previous Ponds Repurposing Project removed
the pond area between the stage and the pedestrian
path in front of the seating area. The park’s main
pathway runs between the stage and the seating
area, but the recent City-funded Amphitheater
Improvement Project added an alternative pathway
behind the seating area to detour pedestrians during
a performance.

H-6 Memorial Park Specific Plan
Picnic Areas
In addition to large festivals and events, Memorial
Park offers spaces for smaller gatherings, such as
birthday parties, lunch meetups, and play dates.

The park has multiple picnic areas for drop-in use,
as well as a large reservable picnic area, which
accommodates social gatherings of all sizes. These
areas are largely without shade, which inhibit their
use on hot and sunny days.

The reservable picnic area is located west of the
Quinlan event lawn on a slightly raised platform
area. This picnic area has a capacity of 113 people
with 16 picnic tables, 2 serving tables, 3 barbeques,
and a counter area with a sink. Trees surround the
area but there is minimal shade directly over the
space. Electricity is available with a reservation to
further enhance the usability of this key amenity.

There are two smaller general use picnic areas around
the softball outfield, each with two picnic tables and
two barbeques.

Lastly, there is a large general use picnic area near
the 5-12 year old playground with space for multiple
groups and barbeques. However, there is a lack
of separation between the tables to create clear
groupings.

Appendix H Site Assessment H-7
Multi-Use Lawn Spaces
There are several areas of unobstructed multi-use
lawn in Memorial Park. The northern portion of
the park contains the largest multi-use lawn. It is
rectangular, largely flat, and sits between the Quinlan Community Center and the reservable picnic area.

The lawn is bounded on the remaining sides by a
walking path within an alley of trees. The park also
has smaller lawn spaces serving passive use activities.

Playgrounds
There are two playgrounds at Memorial Park. A
playground appropriate for 2-5 year old children is
located on the north end of the site, situated between
the softball field and tennis courts. A playground
appropriate for 5-12 year old children is located on the southern end of the site adjacent to Anton Way and
the amphitheater. Both playgrounds are connected
by pathways, within walking distance of restrooms,
and have unshaded seating areas. Playgrounds are
buffered from vehicle traffic by other park amenities.

Both playgrounds provide composite play structures
focusing on play elements of brachiating, climbing,
sliding, and swinging. Balancing, spinning, and
sensory development are lacking in both structures.

Additionally, the composite play structures lack clear
paths of travel and accessible ramps. The playground
surfacing is composed of wood fiber surfacing
bounded by concrete curbs, which does not provide
an accessible transition.

H-8 Memorial Park Specific Plan
Softball Field
Memorial Park features the only lighted softball field
in the City. The softball field is primarily used by
Cupertino Parks and Recreation sponsored leagues
and local teams, but is also available for drop-ins and reservations during the weekends and off-season.

This field attracts players and spectators from around
the entire South Bay region given the high quality of
this amenity.

Tennis Courts
There are six lighted first come, first served tennis
courts, one of which is dual-striped for pickleball.

The tennis courts are oriented north/south and are
divided by a low fence with gaps to allow movement
between courts. The tennis court area is protected by
a high fence with privacy and wind screens.

Spectator Seating
The tennis courts and softball field both feature
spectator seating consisting of concrete and brick
terraced seat walls embedded into a bermed area.

The spectator seating wraps around the softball
field’s home base, protected by sports netting and
partially shaded by trees. For the tennis courts, the
spectator seating runs along the western edge and
perpendicular to the sport’s direction of movement,
providing an optimized viewing experience for
games happening in the westernmost court. The
spectator seating directly connects to the adjacent
court via a gate in the low fencing. Both seating areas are reached by concrete stairs and do not feature
handrails or ramps.

Restrooms
There are two public restrooms in Memorial Park.

One restroom is located under the spectator seating
berm west of the tennis courts, and the other is behind the amphitheater’s audience seating area facing the
playground. These two restrooms are not sufficient
for the quantity of park visitors during heavy-
use times, and organizers often need to provide
additional portable toilets for events. Furthermore,
the restrooms are somewhat hidden away from the
more commonly used areas of the park, making the
public less aware of their availability.

Appendix H Site Assessment H-9
Maintenance and Storage Areas
There are three maintenance and storage areas in
the park. The primary maintenance storage area is
located in the northwest corner of the park behind the
softball field backstop. It has vehicle access from the Mary Avenue parking lot and the end of Christensen
Drive. The space is used by grounds maintenance
staff. The storage container located between the
softball field and the reservable picnic area is used
by the City’s Emergency Services to support the park
as an evacuation center and Quinlan Community
Center as an emergency shelter. The storage shed
located north of the softball field on the third base
line is used for softball equipment.

Cell Tower
The cell tower, located behind the softball outfield,
has an active lease through 2040. The cell tower and
the associated transformers cannot be relocated.

Seating
Scattered throughout the park are seating
opportunities. Most seating is arranged around
another park amenity, such as benches oriented
towards a playground or the amphitheater seating
facing the stage. Picnic tables are arranged organically throughout the park. There are several benches
and seat walls found along paths, such as near the
Cupertino Senior Center, the Veterans Memorial, and
the Quinlan courtyard area.

Drinking Fountains
There are drinking fountains north of the multi-use
lawn by the Quinlan Community Center, adjacent to
the restroom behind the amphitheater, and near the
softball field.

Trash Receptacles
There are trash and recycling receptacles throughout
Memorial Park, specifically near all picnic areas, with a compost container at the reservable picnic area.

Trash receptacle styles vary throughout the park.

H-10 Memorial Park Specific Plan
Trees and Landscaping
Memorial Park has several types of trees and
landscaping zones as shown in Figure H-2.

Trees
The Tree Inventory Report (Appendix B) studied
almost 500 trees within Memorial Park’s 22-acre area.

Most trees in the park are ornamental species or non-
native species that are commonly observed in the
region. A total of 28 species were identified, most of
which were Coast Redwood, Callery Pear, Coast Live
Oak, and Japanese Flowering Cherry.

Of the trees that were studied, approximately 80%
were identified as moderate to high suitability for
preservation. There are approximately 80 trees that
were assessed as low suitability and are recommended
for removal. Low suitability trees have poor health
or significant defects that cannot be abated with
treatment. All public trees, regardless of condition,
have protections as outlined in the City Municipal
Code and will require permit for removal.

Cherry trees have significance in the park—in
1983, the City was gifted 200 Japanese Flowering
Cherry trees from the City of Toyokawa, Japan to
commemorate the fifth anniversary of their Sister
City relationship. Memorial Park remains the home
of the annual Cupertino Cherry Blossom Festival
held every last weekend in April. Two of the Sister
City Japanese Flowering Cherry trees have stone
plaques. Although these do not meet the definition of
heritage trees as per the City Municipal Code Section

14.18, they will be preserved as part of the Memorial
Park Specific Plan.

Veterans Memorial is surrounded by a peaceful grove
of Red Maple trees. There is a Chinese Pistache tree
planted in memory of a City staff member adjacent to
the amphitheater.

Landscape Zones
The majority of Memorial Park’s landscape is
composed of lawn with little to no ornamental or
habitat planting. Planting or mulch areas occur near
the Quinlan Community Center, Cupertino Senior
Center, parking lots, and park edges.

The lawn areas require significant quantities of water
to support the park’s current programming and
require maintenance after large community events.

Cultural Elements
Memorial Park has several important cultural
elements, shown on Figure H-3.

Historic Gazebo
The original construction of the park included the
installation of the gazebo, now identified as a historic site in the General Plan. The wood trim was salvaged
from one of the Enoch Jasper Parrish homes, a local
architect and builder responsible for many of the
early homes in Cupertino. The Parrish family owned
the orchard that Memorial Park presently sits on—
their home was located where the Cupertino Senior
Center is today. In 1994, the Rotary Club of Cupertino
renovated the gazebo, now using it as a logo and
recognizing its contributors with the "Gazebo
Award."
Veterans Memorial
The Veterans Memorial was dedicated on November
11, 2007. The Veterans Memorial features a statue
titled “The Guardians,” which depicts Matthew
Axelson and James Suh, two Navy SEALs from
Cupertino who died in battle. The Veterans Memorial
also features a flagpole, a wall of honor with names
of other Cupertino residents who gave their lives in
the line of duty, and many engraved pavers.

Stone Lanterns
There are two stone lanterns in Memorial Park.

One was located in the center of the now-removed
pond. Both stone lanterns were gifted to the City of
Cupertino by the City of Toyokawa, Japan in 1988 to
commemorate the tenth anniversary of the Sister City
relationship. Both statues have engraved dedication
plaques.

Public Art
A lightpole for the softball field has a metal figure
of a player reaching for a catch. The painted bench
in front of the Cupertino Senior Center on Stevens
Creek Boulevard depicts two women collecting
cherry blossoms and reads “Cupertino-Toyokawa
Sister Cities Inc / Connecting Globally Since 1978.”

Signage and Wayfinding
The main park sign is located to the east of the
Cupertino Senior Center and can be seen from
Stevens Creek Boulevard. Both the Cupertino Senior
Center and the Quinlan Community Center have
signage along their street frontage (Figure H-6).

To advertise upcoming events and festivals at
Memorial Park, temporary event signage is commonly
installed in two locations: at the corner of Stevens
Creek Boulevard and Anton Way, and the corner of
North Stelling Road and Alves Drive.

There are informational signs posted around the
park. Signs near the softball field and tennis courts
list the hours and rules of use. There is a scoreboard in the softball outfield. The large reservable picnic area opposite Quinlan Community Center includes a sign
about reservations. Additional informational signage
throughout the park includes signs discouraging
feeding of the geese, promoting smoke-free parks,
instructing dog owners to clean up after their pets
accompanied by bag dispensers, and designating
non-vehicular areas. There is also signage related to
the parking lots, memorials, and monuments, but
there is no wayfinding signage in the park.

Lighting
Site lighting is provided throughout the park along
the majority of pathways, near amenities, on the
recreational buildings, and within the parking lots
(Figure H-7).

Light fixture styles are uniform throughout the park
but vary within the tennis courts and softball field
to support evening use. Additional light fixtures
occur around seat walls and in the shade structure
in the Quinlan courtyard. Supplemental lighting is
provided during community events. The existing
distribution of lighting does not present significant
safety concerns.

Topography
The park gently slopes from the west at Mary Avenue
towards the east along North Stelling Road. Figure
H-8 shows the park’s topography and denotes the
high points and low points.

Relatively flat areas occur in high-activity zones such as the Quinlan event lawn. The remainder to the site
varies in slope and provides shallow berms in various
locations. The north side of the park provides steeper
sloped berms as visual protection from the adjacent
neighborhood along Christensen Drive. Significant
sloped berms occur at the tennis courts, softball
field, and amphitheater to accommodate seating.

These small hillsides also mitigate visual and noise
concerns to the adjacent residences.
