W PD Section 1 Executive Summary Camp Dresser & McKee Inc. (CDM) was contracted by the City of Cupertino Public Works Department to perform a Phase I Environmental Site Assessment (ESA) of the property located at 22120 Stevens Creek Boulevard in Cupertino, California (referred to as the subject property). The subject property is owned jointly by relatives Mr. Alan Stocklmeir, Ms. Janet Trankle, Ms. Pam Stocklmeir, and Mr. Kurt Stocklmeir. The subject property has been owned by the Stocklmeir family since the early 1900s. The approximately five -acre subject property currently contains two rental residential units and a noncommercial orchard. This Phase I ESA was performed in general accordance with American Society for Testing and Materials (ASTM) standard designation E1527-97 with the purpose of identifying recognized environmental conditions' at the subject property. The results of the Phase I ESA were based upon information provided to CDM by Mr. Alan Stocklmeir (the most knowledgeable of the owners), review of pertinent historical documents, and observations specific to environmental conditions made by CDM during a site walkthrough of the subject property conducted on April 22, 1999. The subject property was assessed for recognized environmental conditions with respect to hazardous substances, solid waste/non-hazardous waste, polychlorinated biphenyls, asbestos - containing materials, air quality, storage tanks, water, wastewater, storm water, herbicide and pesticide use, and lead-based paint. During the site walkthrough, the subject property appeared to be well maintained. Based on CDM's site walkthrough, interviews, and review of site-specific information, there were no indications that prior or current use of the subject property has resulted in recognized environmental conditions. No evidence was discovered that would indicate that adjacent properties caused recognized environmental conditions at the subject property. However, due to the age of the structures at the subject property it is likely asbestos -containing material (ACM) and lead-based paints were used during construction and any renovations. The existence of friable and/or non -friable ACM is possible in the wallboard, roofing, flooring, and chimney materials. During the site walkthrough, CDM made cursory visual observations for ACM and observed no material suspected of containing friable ACM. Prior to any renovation or demolition of the buildings at the subject property, CDM recommends a certified asbestos As used in ASTM E1527-97, "recognized environmental condition' means the following: The presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicated an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property. The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term is not intended to include de minimis conditions that generally do not present a material risk of harm to public health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies" (ASTM, 1997). CDM Camp Dresser & McKee 1-1 JACUPERT[ N\PHASE-I\SEC1. WPD Cupertino Public Works Department Section 1 Phase I Environmental Site Assessment Executive Summary consultant conduct an asbestos survey of the buildings. During the site walkthrough, flaking paint and paint chips were observed on the window sills of the shop building and one pump house. Based on the extent of flaking paint, the potential for soil in contact with paint ships to have elevated levels of lead from the lead-based paint is minimal. In addition, the subject property served as a commercial orchard until the late 1960s. It is possible, although no evidence was fo-und during this Phase I ESA, that the potential mismanagement (i.e., spill during mixing or dilution and over application) of pesticides from uses associated with the orchard may have adversely impacted the subject property. The potential for residual pesticides in the soil to adversely affect human health is minimal. The orchard maintenance that occurs at the subject property could reduce the residual pesticides in the soil. In general, high concentrations of certain pesticide compounds in soil can classify soil as hazardous waste. Prior to any major disturbance of the soil at the subject property, CDM recommends collecting soil samples to determine the extent of impact, if any. Finally, one abandoned well exists at the eastern pump house in the southwest section of the subject property. If the well will no longer be used, CDM recommends properly destroying the well with the approval of the Santa Clara Valley Water District. This Executive Summary is not intended to be read as a stand alone document. The reader should review the detailed information regarding each item in the following sections: Section 3, Property Description; Section 4, Records Review; and Section 5, Site Reconnaissance and Interviews. CDM Camp Dresser & McKee 1-2 JACUPERTIMPHASE-RSEM M Section 2 Introduction This section describes the purpose of the study and presents the scope of work as well as limitations to the investigation. 2.1 Purpose CDM was contracted by the City of Cupertino Public Works Department to perform a Phase I ESA of the subject property located at 22120 Stevens Creek Boulevard in Cupertino, California, for the purpose of identifying recognized environmental conditions. 2.2 Description of Work CDM received written authorization to proceed on April 13, 1999 from Mr. Bert Viskovich of the City of Cupertino Public Works Department. Upon authorization to proceed, CDM arranged a site walkthrough of the subject property through Mr. Alan Stocklmeir, one of the owners of the subject property. On April 22,1999, CDM met with Mr. Stocklmeir at the subject property to discuss background information pertinent to the assessment of the subject property. After the meeting, CDM conducted a site walkthrough of the subject property, which consists of six buildings and an orchard of approximately 170 orange, walnut, and apricot trees. Mr. Stocklmeir accompanied CDM during the site walkthrough and provided information regarding the current and historical uses of the subject property. Observations made by CDM were noted and photographs of the subject property were taken during the site walkthrough. Select photographs of the subject property are provided in Appendix A. Appendix B contains information reviewed pertinent to the subject property. In addition, a search of federal, state, and local environmental databases was conducted by Environmental Data Resources, Inc. (EDR). The database search report provides information regarding any past or current hazardous waste disposal sites; reported petroleum or hazardous waste releases; listed hazardous waste generation, transportation, storage, or disposal facilities; listed solid waste disposal facilities; report leaking underground storage tanks; or listed underground storage tanks at the subject property and properties in the vicinity of the subject property. A copy of the EDR database report is provided in Appendix C. Cursory observations were made of surrounding properties listed in the EDR database during an drive-through survey of the area. During April 20 through May 5, 1999, various federal, state, and local environmental regulatory agencies were contacted as part of an investigation of the history of the subject property and to determine whether prior use of the subject property has resulted in recognized environmental conditions. Agency personnel were also questioned about the existence of recognized CDM Camp Dresser & McKee 2-1 JACUPERTIN\PHASE-1\SEC2. W PD Cupertino Public Works Department Phase I Environmental Site Assessment Section 2 Introduction environmental conditions in the vicinity of the subject property. Names and affiliations of persons contacted for information for this Phase I ESA and a list of information reviewed are provided in Section 7. Copies of information request letters sent to environmental regulatory agencies and subsequent responses are provided in Appendix D. 2.3 Limiting Conditions and Methodology Used The results of this Phase I ESA are based on interviews with environmental regulatory agency and subject property personnel, a walkthrough of the subject property, and a review of acquired environmental regulatory agency documents and subject property information. The conclusions, therefore, represent CDM's professional opinion based on these aforementioned sources of information. This report has been prepared for the exclusive use of the City of Cupertino Public Works Department. It is not intended for use by other parties. If evidence of recognized environmental conditions are discovered based on CDM's review of information requested but not as yet provided, CDM will notify the City of Cupertino Public Works Department of these newly discovered issues. Therefore, is supplemental information warrants, CDM reserves the right to change conclusions and recommendations stated in this Phase I ESA. CDM Camp Dresser & McKee 2- 2 J:\CUPERT1N\PHASE-RSEC2.WPD Section 3 Property Description 3.1 Location and Legal Description The subject property is located at 22120 Stevens Creek Boulevard in Cupertino, California, in southwest Santa Clara County. Figure 3-1, Topographical Relief Map of Cupertino, California, depicts the location of the subject property with respect to geographical features. The Assessor's parcel map was obtained from the Santa Clara County Assessor's Office. The subject property consists of Assessor's Parcel Number 357-09-053. The deed for this parcel, dated March 28, 1984, was obtained from the Santa Clara County Recorder's Office. Appendix B includes a copy of the parcel map and the deed. According to the deed, the legal description of subject property is as follows: Beginning at the point of intersection of the Southerly line of Stevens Creek Road, as it formerly existed 40 feet wide, with the center line of Stevens Creek; thence in a general Southerly direction along the center line of Stevens Creek ... to a station designated D.S. 5 ... thence leaving the center line of Stevens Creek and running along the Eastery line of Monta Vista Park ... and along the Easterly line of Inspiration Point, Monta Vista ... to a pipe on said Southerly line of Stevens Creek Road; thence along said Southerly line of Stevens Creek Road ... to the point of beginning, containing 4.857 acres of land, more or less, and being a portion of the San Antonio Rancho, and being shown upon that certain map entitled, "Map of a survey made for Adelheid M. Stocklmeir in the San Antonio Ranch", which Map was filed for records in the office of the Recorder of the Recorder of the County of Santa Clara, State of California, on December 29, 1915, in Book "O" of Maps, page 88. 3.2 Property and Vicinity Characteristics The subject property is located at the southwest corner of the intersection of Stevens Creek Boulevard and Stevens Creek in Cupertino, California. Stevens Creek borders the subject property on its east and south sides. Blackberry Farm Park, consisting of a golf course and picnic facilities, is located on the east side of the creek, south of Stevens Creek Boulevard. Residential housing is situated north and west of the subject property. A wooden fence lines the western boundary of the subject property, except for a short section that is a closed wrought iron gate. The gate leads to Dean Court, one of the private roadways adjacent to the subject property. Main access to the subject property is provided on the north side by a gravel driveway entering from Stevens Creek Boulevard. 3.3 Description of Structures and Other Improvements Eight structures are located on the subject property: a main residence, studio apartment with an attached garage, a shop building, two open-air garages, and three pump houses. Figure 3-2 presents the layout of the subject property. The main residence, the studio apartment, and the shop CDM Camp Dresser & McKee 3-1 JACU P ERTI N\PHASE-I\S EC3.

The open-air garages have wooden frames with corrugated heavy plastic roofs. The main residence and studio apartment were built in approximately 1900, and the shop building, garages, and pump houses were built around 1950. The pump at the pump house located at the northern end of the property was installed around 1920 Photograph 4). It provides water from Stevens Creek for the garden area near the main residence. Historically, it pumped water for use in irrigating the orchard on the subject property. The pump system consists of a PVC pipe that enters the creek, a pressure tank to hold the creek water, the pump, and garden hoses used for distribution. The western pump house at the southern end of the property pumped creek water for irrigating the orchard (Photograph 5). The pump system consisted of a trap door in the creek bed, a concrete holding pit, and the pump. The holding pit is located in the concrete structure between the western and eastern pump houses. This concrete structure, covered with wooden planks, is separated into two comparments: one for the creek water and one for the groundwater well. According to Mr. Stocklmeir, the creek water pump was installed in the 1920s or 1930s. The 8 -foot by 10 -foot pump house is now used for storage space. The pump is operable but has not been used in approximately twenty years. The eastern pump house at the southern end of the subject property houses a pump and equipment for a drinking water well (Photograph 6). The groundwater well is located in the concrete structure between the two pump houses. The well was installed between 1900 to 1905. Mr. Stocklmeir is unaware of the depth of the well; however, Mr. Stocklmeir stated that distribution pipes at least 120 feet long have been pulled out of the well. The well was used as the main drinking water source for the subject property until the property was connected to the City's water lines. The well system consists of pipes inserted to reach the groundwater, the pump, and a concrete pressure tank. The pump is inoperable and has not been used in over 50 years. The 8 -foot by 10 -foot pump house is now used for storage space. 3.4 Current Uses of Property Since 1996, Mr. Stocklmeir has rented out the main residence and the studio apartment. The orchard, consisting of approximately 150 orange trees and 20 walnut and apricot trees, fills the majority of the subject property not occupied by the main residence, pump houses, and other structures (Photographs 7 and 8). The orchard no longer functions as a commercial operation. The oranges are picked every March by volunteers from the Second Harvest Food Bank of Santa Clara and San Mateo Counties in San Jose, California. According to Mr. Stocklmeir, the extent of current orchard maintenance is discing the orchard surface two to three times a year. 3.5 Past Uses of Property According to Mr. Stocklmeir, the subject property has been owned by the Stocklmeir family since the turn of the century. Mr. Stocklmeir's great grandmother lived at the main residence from 1900 until the mid -1940s. His grandparents then lived at subject property from 1949 to 1996, at which time the main residence and studio apartment were rented out. CDM Camp Dresser & McKee 3-2 JACUPERTIMPHASE-RSEM M Cupertino Public Works Department Section 3 Phase l Environmental Site Assessment Site Description and History Until the late 1960s, the subject property ran a commercial orchard. The orchard area was primarily walnut trees and customers would come to the property to pick the nuts. A portion of the orchard was leased out for growing flowers. The orchard became economically unfeasible and the commercial business ended in the late 1960s. In the mid-1970s, the majority of the walnut trees were removed and replaced with orange trees. About twenty walnut and apricot trees remain at the northern end of the orchard. 3.6 Current and Past Uses of Adjoining Property The Stocklmeir family owned the land adjacent to the west side of the subject property before the area was developed into residences. That area grew additional walnut trees and was also leased out for flower growing. The Stocklmeir family sold that land in 1976. Aerial photographs, available from Pacific Aerial Surveys, were reviewed. The photographs were from the years 1960, 1968, 1978, and 1988. Appendix B presents copies of these aerial photographs. In the 1960 photograph, the surrounding area was used for agricultural and residential purposes. Orchards occupied the subject property, the adjacent property to the west, and portions of the area east of the subject property which is currently Blackberry Farm Park. The main residence is visible through the vegetation on the subject property. In the 1968 photograph, more of the surrounding area has been converted to residential uses. Orchards occupy the subject property and the adjacent property to the west. The area east of the subject property has been developed into a golf course. In the 1978 photograph, the majority of the surrounding area is residential property. On the subject property, the main residence, shop, garages, and pump hoses are visible. The studio apartment is not visible due to vegetation at the subject property. The northern portion of the orchard area appears to be heavily planted, but the southern half is either open space or lightly planted. Housing has been developed along Scenic Boulevard, adjacent to the subject property to the west. In the 1988 photograph, a few small agricultural areas still exist north and east of the subject property. The surrounding area is residential. At the subject property, all of the current structures are visible. The northern portion of the orchard is planted with large trees, while the southern portion has smaller trees.

South Bay Site Management System (SOUTH BAY) - subject property only; and In addition, EDR searched former manufactured gas (Coal Gas) sites for a radius search of 1 mile. 4.2 Database Search Results A summary of listed environmental sites within the requested search distance follows. National Priorities List (NPL) Sites The National Priorities List (NPL) is a list of the nation's most serious hazardous waste sites. NPL sites are those sites which the United States Environmental Protection Agency (USEPA), under its Superfund program, has determined to be a significant threat to public health. The Records of Decision (ROD) document mandates a permanent remedy at an NPL site containing technical and health information to aid the cleanup. The USEPA has the authority to file liens (NPL Liens) against real estate property in order to recover remedial action expenditures or when the property owner receives notification of potential liability. The database searches indicated no NPL and ROD sites within a one -mile radius of the subject property. There are no liens against the subject property and the subject property was not on nor deleted from the NPL. Resource Conservation and Recovery Act (RCRA) Sites The RCRIS databases contain data compiled for RCRA and the Hazardous and Solid Waste Amendments of 1984. RCRIS lists sites which treat, store or dispose of hazardous waste as defined by RCRA. RCRA administration action tracking system (RAATS) contains records based on enforcement action issued under RCRA pertaining to major violators and includes administrative and civil suits. Under RCRA, the CORRACTS database contains hazardous waste haulers which are undergoing corrective action. The RCRIS database indicates that no TSD sites are located within a 0.5 -mile radius of the subject property. The subject property is not listed in the RAATS database. The CORRACTS database search indicated one CORRACTS site within a one -mile radius of the subject property. Zilog Incorporated is located approximately 0.75 miles southeast of the subject property. Zilog manufactured silicon, semiconductor wafers, and microprocessors, and was listed as a hazardous waste storage facility. Zilog operated three USTs: one for storage of waste solvents CDM Camp Dresser & McKee 4- 2 JACUPERTIN\PHASE-1\SEC4. W PD Cupertino Public Works Department Phase l Environmental Site Assessment Section 4 Records Review acetone, isopropanol, freon, trichloroethane, xylene, and n -butyl acetate); one for containment of potential solvent spills; and one for containment of potential sulfuric, nitric, and hydrofluoric acid spills (J.H. Kleinfelder & Associates, 1983). J.H. Kleinfelder & Associates concluded no soil degradation had occurred from the operation of the acid spill tank, and no additional analytical testing was necessary for the waste solvent storage and spill containment USTs due to only trace levels (less than 20 micrograms per kilogram) of tetrachloroethane, toulene, and benzene found in soil samples near the other two USTs (J.H. Kleinfelder & Associates, 1983). According to Zilog, those chemicals were not used in their operations. In 1987, the California Department of Health Services (DHS) determined that no contamination resulting from Zilog's operations remained at the site (DHS, 1987). The Zilog site was officially closed by the DHS in 1988 (DHS, 1988). Due to the site closure by DHS, trace levels of contaminants in the soil, and distance from the subject property, it is unlikely that the site has impacted the subject property. RCRA Registered Large and Small Generators (LG GEN, SM GEN) of Hazardous Waste The EPA's RCRA facility database lists facilities which report generation, storage, transportation, treatment or disposal of hazardous waste. RCRA Large Generators (LG GEN) are facilities which generate at least 1,000 kilograms of non -acutely hazardous waste per month while Small Generators SM GEN) produce less per month. No SM GEN or LG GEN sites are located within a 0.25 -mile radius of the subject property. Comprehensive Environmental Response, Compensation and Liability Act CERCLA) Sites The CERCLA Information System (CERCLIS) supports EPA Headquarters and regions for the management and oversight of the Superfund program. CERCLA sites are either on the NPL or are in screening and assessment phase for possible inclusion on the NPL. CONSENT decrees are major legal settlements that establish responsibility and standards for cleanup at NPL sites. CERC- NFRAP sites are those CERCLA sites where no contamination was found, contamination was removed quickly, or the contamination was not serious enough to require NPL consideration. No CERCLIS or CONSENT sites are located within a 0.5 -mile and 1 -mile radius of the subject property, respectively. The subject property was not listed on the CERC-NFRAP database. PCB Activity Database System (PADS) The PADS identifies generators, transporters, commercial storers and/or brokers and disposers of polychlorinated biphenyls (PCBs) who are required to notify the EPA of such activities. The PADS database search indicated that the subject property is not a PADS site. Emergency Response Notification System (ERNS) The ERNS list is a national database used to collect information on reported accidental releases of oil and hazardous substances. Spill reports are made to federal authorities including the EPA, the CDM Camp Dresser & McKee 4- 3 JAC U PERTI N\PHASE-1\SEC4.

The ERNS database search indicated that the subject property is not an ERNS site. Facility Index System (FINDS) FINDS contains both facility information and references to other sources that contain more detail. The FINDS database search indicated that the subject property is not a FINDS site. Toxic Release Inventory Database (TRIS) Section 313 of the Emergency Planning and Community Right -to -Know Act (also known as SARA Title III) of 1986 requires the EPA to establish an inventory of toxic chemicals emissions from certain facilities. Facilities subject to this reporting are required to complete a Toxic Chemical Release Form Form R) for specified chemicals. The TRIS database search indicated that the subject property is not a TRIS site. Toxic Substances Control Act (TSCA) TSCA identifies manufactures and importers of chemical substances included on the TSCA Chemical Substance Inventory list. It includes data on the production volume of these substances by plant site. The TSCA database search indicated that the subject property is not a TSCA site. Material Licensing Tracking System (MLTS) MLTS is maintained by the Nuclear Regulatory Commission and contains a list of approximately 8,100 sites which possess or use radioactive materials and which are subject to NRC licensing requirements. The MLTS database search indicated that the subject property is not a MLTS site. Hazardous Materials Information Reporting Systems (HMIRS) The HMIRS database contains hazardous material spill incidents reported to the Department of Transportation. The HMIRS database search indicated that the subject property is not a HMIRS site. California Annual Workplan (AWP) California Department of Toxic Substance Control's Annual Workplan, formerly Bond Expenditure Plan (BEP), identifies known hazardous substance sites targeted for cleanup.

W PD Cupertino Public Works Department Phase I Environmental Site Assessment Section 4 Records Review Calsites (CAL -SITES) The CAL -SITES database contains potential or confirmed hazardous substance release properties as reported by the California Department of Toxic Substance Control (DTSC). The CAL -SITES database search indicated one CAL -SITES site within a one -mile radius of the subject property. Kaiser Aluminum and Chemical Corporation (KACC) is located just under one mile west of the subject property. In 1987, KACC decontaminated and closed a paint/sludge UST. Oil and grease was found in the surrounding soil at concentrations of 1,100 to 2,600 milligrams per kilogram (mg/kg). A subsequent investigation found that samples from underlying soils had chromium and lead levels consistent with regional background levels, and purgeable and aromatic hydrocarbons levels below detection limits. One groundwater sample from the site exceeded the Primary Drinking Water Standard for chromium (Exceltech, Inc., 1988). In 1988, a kerosene spill occurred at KACC. Excavated contaminated soil contained high levels of vegetable oil. Subsequent analysis of samples from the area of the release indicated vegetable oil in the soil samples at concentrations from 19 to 24 mg/kg, and in a groundwater sample at a concentration of 100 micrograms per liter. Total petroleum hydrocarbon (TPH) as kerosene was found in soil samples ranging in concentration from 14 to 32 mg/kg, but was not detected in groundwater. TPH as kerosene concentrations in soil were below the action level of 100 mg/kg. No action level exists for vegetable oil in soil or groundwater (ENSCO Environmental Services, 1988). No documentation from the San Francisco Bay Regional Water Quality Control Board (RWQCB) or any other environmental agency on action taken at the KACC site existed in the RWQCB files. Mr. David Bar with the RWQCB stated the KACC case is inactive, a status which usually occurs when there is a shortage of staff to investigate the case at its onset. Even though the groundwater flow is the area is to the east, Mr. Bar indicated that the subject property was unlikely to have been impacted by the KACC site due to the distance, just under one mile, between the two sites. Proposition 65 (Notify 65) Notify 65 contains facility notifications about any release which could impact drinking water and thereby expose the public to a potential health risk. The Notify 65 database search indicated one Notify 65 site within a one -mile radius of the subject property. Arco Service Station #6182 is located approximately 0.40 miles west of the subject property. The site was also listed in the LUST Region 2 database as having reported a release from a gasoline UST in 1988. According to the EDR report, the Santa Clara Valley Water District SCVWD) signed off on the site on July 29, 1996. Due to the case closure by the SCVWD, it is unlikely that the Notify 65 site has impacted the subject property. California Hazardous Material Information Reporting System (CHMIRS) The CHMIRS contains hazardous material spill incidents reported to Department of Transportation.

W PD Cupertino Public Works Department Section 4 Phase l Environmental Site Assessment Records Review property. State Index of Properties with Hazardous Waste (Cortese) The Cortese database identifies public drinking water wells with detectable levels of contamination, hazardous substance sites selected for remedial action, sites with known toxic material identified through the abandoned site assessment program, sites with underground storage tanks having a reportable release and all solid waste disposal facilities from which there is known migration. The source is the California Environmental Protection Agency. The Cortese database search indicated two Cortese sites within a one -mile radius of the subject property. The Kaiser Aluminum and Chemical Corporation is located just under a mile from the subject property. A detailed description of the release and subsequent investigation can be found above in the section on CAL -SITES sites. The other Cortese site is the Measurex Corporation and is further discussed under LUST sites. Toxic Pits Toxic Pit sites are suspected of containing hazardous substances where cleanup has not yet been completed. The Toxic Pits database search indicated no Toxic Pit sites within a one -mile radius of the subject property. California Spills, Leaks, Investigation & Cleanup (CA SLIC) CA SLIC sites are sites that have impacted groundwater or have the potential to impact groundwater. The CA SLIC database is provided by the RWQCB. The CA SLIC database search indicated one CA SLIC site within a 0.5 -mile radius of the subject property. The Cupertino Post Office is located approximately 0.45 miles east of the subject property. The EDR report states a release from a waste oil UST occurred at the site. The RWQCB closed the site investigation on August 10, 1993. Based on the case closure by the RWQCB, it is unlikely that the CA SLIC site has impacted the subject property. State Landfill The Solid Waste Facilities /Landfill SITES site (SWF/LF) type records typically contain an inventory of solid waste disposal facilities or landfills in a particular state. Depending on the state, these may be active or inactive facilities or open dumps that fail to meet RCRA Subtitle D Section 4004 criteria for solid waste landfills or disposal sites. The State Landfill database search indicated no state landfill sites located within a 0.5 -mile radius of the subject property. CDM Camp Dresser & McKee 4-6 JACU PERTI N\PHASE-1\SEC4. WPD Cupertino Public Works Department Phase l Environmental Site Assessment Section 4 Records Review Underground and Aboveground Storage Tanks (UST/AST), Leaking Underground Storage Tanks (LUST) The Hazardous Substance Storage Container Database is a historic listing of UST and LUST sites. The source of the database is from the State Water Resource Control Board (SWRCB). The database search located no registered UST sites within a 0.25 -mile radius. The AST database lists registered ASTs as reported by the SWRCB. The EDR database reported no ASTs at the subject property. The LUST database search indicated 11 LUST sites within a 0.5 -mile radius of the subject property. Of the 11 sites listed, "Dennis Hall Property," "Arco #6182," "U.S. Postal Service," and "Measurez Corporation" are duplicates. Of the remaining seven LUST sites, six site investigations have been closed ("Facciola Residence," "Dennis Hall Property," "Arco," "US Postal Service," "Higdon, Alley, Kolb" and "Measurex Corporation"). Neither the RWQCB nor the SCVWD has a file for the remaining site, the Mobile Service Station. The RWQCB and the EDR database report that the site was removed from the SCVWD's LUST database. Ms. Jeanette Townsend of the SCVWD, the lead agency for the site, confirmed that that agency has no file for the site and if the site was removed from the LUST database there was no contamination problem at the site. This concurs with the EDR database which reports the soil contamination occurred at such a low level as to not pose a threat to water quality. Based on the information from the RWQCB and SCVWD, it is unlikely that the LUST sites have impacted the subject property. Waste Management Unit Database (WMUDS/SWAT) WMUDS/SWAT is used by the SWRCB to track and inventory waste management units and consist of 12 separate databases. The WMUDS/SWAT database search indicated there are no WMUDS/SWAT sites within a 0.5 -mile radius of the subject property. Hazardous Waste Information System (HAZNET) The California Environmental Protection Agency provides a database (HAZNET) from the manifest data extracted from copies of hazardous waste manifests received each year by the DTSC. The HAZNET database search indicated four HAZNET sites within a 0.25 -mile radius of the subject property. Of the four sites, "Clarks Auto Parts & Machine" is a duplicate. The three remaining sites Dan Facciola", "Lynn Markey", and "Clarks Auto Parts & Machine") do not have files at the California Environmental Protection Agency. The DTSC is currently reviewing their files to determine if information exists on the remaining sits. If information does become available that suggests a HAZNET site has had the potential to impact the subject property, CDM will notify the Cupertino Public Works Department. California Facility Inventory Database (FID) California Environmental Protection Agency provides the Facility Inventory Database (FID) which contains a historical listing from the SWRCB. CDM Camp Dresser & McKee 4-7 JACUPERTI N\PHASE-1\SEC4. W PD Cupertino Public Works Department Phase I Environmental Site Assessment Section 4 Records Review The FID database search indicated no FID sites within a 0.25 -mile radius of the subject property. California Waste Discharge System (CA WDS) CA WDS sites are sites which may have been issued waste discharge requirements by the SWRCB. The CA WDS database search indicated the subject property is not a CA WDS site. South Bay Site Management System (SOUTH BAY) The SOUTH BAY database lists groundwater pollution cases in the Santa Clara Valley where the regulatory lead is the San Francisco Bay RWQCB. The SOUTH BAY database search indicted the subject property is not a SOUTH BAY site. Orphan Sites Orphan sites are sites listed in any of the databases EDR searched and are potentially within one mile of the subject property, but cannot be accurately mapped. The EDR database search indicated eight orphan sites potentially within one -mile of the subject property. Two sites are duplicates either of sites on the orphans list or sites from the other databases ("Arco Stn #495" and "Kaiser Aluminum"). Based on the partial addresses provided for the orphan sites, CDM concluded five of the sites to be greater than one -mile from the subject property: "Arco Service Station #495," "Texaco," "Doneervyn's," and "Rancho Service Center." The remaining site, Hanson Permanente Cement, formerly Kaiser Cement Corporation, is located just under one mile west of the subject property. A number of USTs in five areas at the site have been removed or closed in place. In 1993, Kaiser Cement Corporation removed one 10,000 -gallon diesel UST and two 10,000 -gallon gasoline USTs from the Upper Service Station area. Soil samples revealed only minor levels of total petroleum hydrocarbons. TPH as gasoline was detected at a maximum concentration of 22 mg/kg, and TPH as diesel was not detected above laboratory reporting limits (RWQCB, 1995). The RWQCB closed the site investigation of this area in 1995. A copy of the closure letter is included in Appendix D. According to SCVWD files, four 1,000 -gallon diesel USTs were removed from the Lower Service Station. Floating product was observed in the tank pit and excavated soils had a strong diesel odor, but no soil samples were collected. One 4,000 -gallon diesel UST was removed from the Emergency Generator Area. During removal, the tank appeared undamaged but its lines and plumbing showed signs of leakage. Excavated soil had a diesel odor and contained product. No soil samples were obtained from this area. USTs were also removed from the Garage and Oil House areas. At least two of these USTs were closed in place. According to the SCVWD, no further remedial work is necessary at the Garage and Oil House areas. On March 2, 1999, the SCVWD requested Hanson Permanent Cement submit a work plan to define the extent of soil and groundwater contamination at the Lower Service Station and the Emergency Generator Area (SCVWD, 1999). According to Ms. Adele Shepherd with SCVWD, Hanson Permanente Cement submitted a workplan which has been approved by the SCVWD and is now being implemented. CDM Camp Dresser & McKee 4-8 JACUPERTI N\PHASE-I\SEC4. W PD Cupertino Public Works Department Phase l Environmental Site Assessment Section 4 Records Review Even though the groundwater flow is the area is to the east, due to the distance of the Hanson Permanente Cement site from the subject property (just under one mile), the potential is minimal that the LUST site has impacted the subject property. 4.2 Physical Setting The property is located in the west -central portion of the Santa Clara Valley which is a broad structural trough infilled with alluvial sediments. The subject property is within the corporate boundaries of the City of Cupertino. Stevens Creek flows adjacent to the east and south sides of the subject property. The climate in the area maintains a fairly constant temperature due the effects of surrounding bodies of water, the Pacific Ocean and the San Francisco Bay. Summers are cool and often foggy and winters are moderately wet. The subject property experiences the same climatic conditions as much of the Santa Clara Valley which is represented by climate data collected in San Jose. Based on 50 years of climate data, a monthly average minimum temperature of 41.3 degrees Fahrenheit (°F) occurs in January and a monthly average maximum temperature of 82.2 OF occurs in July. Temperature extremes have been recorded at a low of 19 OF in December 1990 to a high of 108 OF in July 1972. The annual average precipitation is 14.61 inches (Western Regional Climate Center, 1999). The subject property is situated in the central part of the Coast Ranges, which is characterized by a series of parallel, northwesterly -trending, folded and faulted mountain chains. In this part of the province, flatland topography is underlain by recent alluvium which is typically underlain by non -marine and marine sedimentary rocks. The region has been folded and faulted as a result of major uplift of the area. The Department of Water Resources (DWR) identifies the Santa Clara Formation as a principle group of the water -bearing units in the Santa Clara Valley groundwater basin (Bulletin No. 118-1, 1975). DWR's report modeled the entire basin and identified preferential groundwater pathways created by highly permeable coarse-grained channel deposits of the Santa Clara Formation which have been intersected by numerous faults. Another study by DWR (Bulletin No. 66-62, 1964) states that the main source of groundwater in the Santa Clara Valley is the younger alluvium and that the Santa Clara Formation is of secondary importance. In addition, the principal aquifers of the area exhibit pressure characteristics so that the groundwater is both confined and unconfined. Groundwater flow in the area generally follows the topography, which would indicate an easterly flow gradient (EMCON Associates, 1993). Groundwater in this area of the Santa Clara Valley is generally a bicarbonate type with sodium and calcium the predominant cations. Although moderately to very hard, the waters are of good to excellent quality and suitable for most uses DWR, 1964). CDM Camp Dresser & McKee 4-9 JACU PEATI N\PHASE-1\SEC4. W PD Section 5 Site Reconnaissance and Interviews On April 22, 1999, CDM met with Mr. Alan Stocklmeir, one of the four owners of the subject property, at the subject property. Mr. Stocklmeir was interviewed by CDM to obtain information regarding the subject property history, existing conditions, and property -specific information related to current and past operations. The Stocklmeir family has owned the subject property since the 1900s, and Mr. Stocklmeir is the most knowledgeable of the current family owners about the subject property. The interview was followed by a walkthrough of the subject property. The subject property was assessed for recognized environmental conditions with respect to hazardous substances, solid waste/non-hazardous waste, polychlorinated biphenyls, asbestos - containing materials, air quality, storage tanks, water, wastewater, storm water, herbicides and pesticides, and lead-based paint. CDM did not access the interior of the buildings on the subject property, but observations were made through the windows. 5.1 Hazardous Substances No hazardous substances were observed at the subject property. Mr. Stocklmeir is not aware of any spills or releases of hazardous substances on the subject property or surround properties. During the site walkthrough, CDM did not observe any operations that would produce hazardous wastes. 5.2 Solid Waste/Non-Hazardous Waste During the site walkthrough, several piles of solid waste were observed at the subject property. One small pile of used wooden shingles is present at the southern end of the site. Along the western boundary of the subject property, small piles of building materials such as metal fencing, lumber, and metal pipes were observed (Photograph 9). Mr. Stocklmeir indicated the shingles were previously used on one of the pump houses, and the building materials are related to his personal contractor business. According to Mr. Stocklmeir, there are no discarded items on the subject property. Residential waste generated at the subject property is disposed of through Cupertino's city-wide trash disposal service. 5.3 Polychlorinated Biphenyls According to Mr. Bob Bondy of Pacific Gas and Electric Company (PG&E), there are two pieces of oil -filled electrical equipment on the subject property. A capacitor bank is located at the northeastern corner of the subject property at the corner of the driveway and Stevens Creek Boulevard. According to Mr. Bondy, the capacitor is labeled as having no PCB -containing fluid. PG&E also operates a pole -mounted transformer located at the southern corner of the subject property. No sticker is affixed to this transformer. According to Mr. Bondy, PG&E does not test transformers for PCBs if they have not been leaking. Mr. Bondy stated that if the residential units at CDM Camp Dresser & McKee 5-1 JACUPERTIN\PHASE-1\SEC5. W PD Cupertino Public Works Department Phase I Environmental Site Assessment Section 5 Site Reconnaissance and Interviews the subject property are demolished, PG&E will remove the transformer. 5.4 Asbestos -Containing Materials The main residence, studio, and the other subject property structures were constructed between 1900 and 1950, before the commercial use of asbestos -containing material (ACM). ACM are usually found in structures built or renovated between the late 1950's and the early 1980's. However, it is likely that during renovations and additions to the building friable and/or non -friable ACM was used. The existence of friable and/or non -friable ACM is possible in the wallboard, roofing, flooring, and chimney materials. During the site walkthrough, CDM made cursory visual observations for ACM and observed no material suspected of containing friable ACM. However, without conducting an asbestos survey, the presence and extent, if any, of ACM at the subject property cannot be determined. 5.5 Air Quality The site walkthrough did not reveal any particulate, gas, odor, or emission to the atmosphere from the subject property that would violate any environmental regulation. No violations for the subject property are on file with the Bay Area Air Quality Management District. 5.6 Storage Tanks According to Mr. Stocklmeir, no USTs are located on the subject property. CDM did not discover any indication that a UST exists or existed at the subject property. One approximately 400 -gallon AST is located on the dirt on the east side of the driveway Photograph 10). According to Mr. Stocklmeir, the AST contained propane used to heat the main residence in the 1930s and 1940s. Use of the AST was discontinued in the mid -1940s or earlier when natural gas became available. To Mr. Stocklmeir's knowledge, the AST is empty. Mr. Stocklmeir is not aware of a permit for the AST or if the AST has been located at any other spot on the subject property. The AST appeared to be in good condition with some light rust along the upper rim and did not appear to be connected to any piping. 5.7 Water, Wastewater, and Storm Water According to Mr. Stocklmeir, a groundwater well was installed at the subject property between 1900 to 1905 by his great grandfather. The well is located outside the eastern pump house located at the southern end of the subject property. The main residence was connected to the city water supply in the 1940s or earlier. Mr. Stocklmeir stated the well is abandoned and has not been used in over 50 years. The well has not been destroyed. A one -compartment septic tank is located on the east side of the driveway, as shown in Figure 3-2 Photograph 11). The approximately 700 -gallon tank services the main residence and the studio apartment. Only sanitary wastewater is generated at the subject property. Mr. Stocklmeir is unaware of when the septic tank was installed, but stated it was there when his grandparents lived at the subject property starting in 1949. To Mr. Stocklmeir's knowledge, no permit exists for the septic tank. CDM Camp Dresser & McKee 5-2 J:\CUPERT1N\PHASE-1\SEC5.WPD Cupertino Public Works Department Phase I Environmental Site Assessment Section 5 Site Reconnaissance and Interviews Mr. Stocklmeir stated occasional stoppages occur every one or two years in the septic tanks lines running from the residences. The commercial service RotoRooter is contracted to clean the lines in those instances. The tank is pumped out every two years by A -Able Septic Tank Company. Three leach lines for the wastewater run underground into the orchard area: one north towards the pump house, and the other two run northeast and east, respectively, into the orchard. Valves to control the flow of the lines are located near the septic tank inside PVC piping. No distressed vegetation was observed in the area of the leach field. Mr. Stocklmeir stated that storm water at the subject property either percolates through the soil or flows east to Stevens Creek. No pavement is present at the subject property except for small patio areas. According to Mr. Stocklmeir, a storm water pipeline runs from the housing development adjacent to the west side of the subject property across the orchard to Stevens Creek via an easement across the subject property. The eastern end of the pipe is visible as a corrugated metal pipe in the western side of the creek bed (Photograph 12). 5.8 Herbicides and Pesticides Use Mr. Stocklmeir hired New View Landscape Service to perform yard work at the subject property consisting of raking and collecting leaves and trimming the bushes. According to Mr. Stocklmeir, no herbicides or pesticides are currently used at the subject property. According to Mr. Stocklmeir, fertilizer has not been used on the orange trees in approximately 10 years. When the orchard produced walnuts for commercial use, the walnut trees were sprayed with herbicides and pesticides. Mr. Stocklmeir stated that mixing or storing of chemicals did not occur at the subject property. The commercial orchard business ended in the late 1960s. No signs of distressed vegetation or stained soil were observed during the site walkthrough. It is possible, although no evidence was found during this Phase I ESA, that the potential mismanagement of pesticides (i.e., a spill during mixing or dilution and over application) from historical uses associated with the orchard may have adversely impacted the subject property. In general, pesticides have low vapor pressures, do not biodegrade, and adhere to soil extremely well. Therefore, even though the property stopped serving as an orchard, pesticide residues may still be present in the soil. Farmers began to use DDT as a pesticide in the 1940s. Usually, DDT does not spread to more than a foot below ground surface (Hayes, 1975). According to Toxicology of Pesticides, "residues of pesticides in soil are rarely important as a source of direct exposure to people" (Hayes, 1975). The only orchard maintenance occurring at the subject property is discing of the soil, which could significantly decrease the residual pesticides at the subject property (Hayes, 1975). The potential for residual pesticides in the soil to adversely affect human health is minimal. Major disturbance of the soil may increase potential for human exposure to residual pesticide potentially present in the soil. In general, high concentrations of certain pesticide compounds in soil can classify soil as hazardous waste. 5.9 Lead -Based Paint Due to the age of the buildings on the subject property, it is likely that lead-based paints have been used. During the site walkthrough, flaking paint and paint chips were observed on the window sills of the shop and on the walls of the western pump house (Photographs 3 and 5). CDM observed no paint chips on the soil at these areas. Based on the extent of flaking paint, the potential for soil in contact with paint ships to have elevated levels of lead from the lead-based paint is minimal. CDM Camp Dresser & McKee 5-3 JAGUPERTIN\PHASE-1\SEC5. W PD Section 6 Conclusions and Recommendations This Phase I ESA is based upon information researched and made available to CDM through May 5, 1999. Any subsequent information received by CDM which modifies the conclusions of this report will be submitted to the City of Cupertino Public Works Department in later correspondence. Based on the information provided to CDM and observations made during the walkthrough of the subject property, no recognized environmental conditions at the subject property were discovered during the performance of the Phase I ESA. No information was discovered that would suggest that off-site properties had released contaminants that would results in environmental contamination of the subject property. However, due to the age of the structures at the subject property it is likely asbestos -containing material (ACM) and lead-based paints were used during construction and any renovations. The existence of friable and/or non -friable ACM is possible in the wallboard, roofing, flooring, and chimney materials. During the site walkthrough, CDM made cursory visual observations for ACM and observed no material suspected of containing friable ACM. Prior to any renovation or demolition of the buildings at the subject property, CDM recommends a certified asbestos consultant conduct an asbestos survey of the buildings. During the site walkthrough, flaking paint and paint chips were observed on the window sills of the shop building and on the wall of the western pump house. Based on the extent of flaking paint, the potential for soil in contact with paint ships to have elevated levels of lead from the lead-based paint is minimal. In addition, the subject property served as a commercial orchard until the late 1960s. It is possible, although no evidence was found during this Phase I ESA, that the potential mismanagement (i.e., spill during mixing or dilution and over application) of pesticides from uses associated with the orchard may have adversely impacted the subject property. The potential for residual pesticides in the soil to adversely affect human health is minimal. The orchard maintenance that occurs at the subject property could reduce the residual pesticides in the soil. In general, high concentrations of certain pesticide compounds in soil can classify soil as hazardous waste. Prior to any major disturbance of the soil at the subject property, CDM recommends collecting soil samples to determine the extent of impact, if any. Finally, one abandoned well exists at the eastern pump house in the southwest section of the subject property. If the well will no longer be used, CDM recommends properly destroying the well with the approval of the Santa Clara Valley Water District. CDM Camp Dresser & McKee 6-1 JACU PERTI N\PHASE-I\SEC6.

Search Results: Search results for the subject property and the search radius, are listed below: Subject Property: The subject property was not listed in any of the databases searched by EDR. TC359034.1s EXECUTIVE SUMMARY 1 EXECUTIVE SUMMARY Surrounding Properties: Elevations have been determined from the USGS 1 degree Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. EDR's definition of a site with an elevation equal to the subject property includes a tolerance of -10 feet. Sites with an elevation equal to or higher than the subject property have been differentiated below from sites with an elevation lower than the subject property (by more than 10 feet). Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multiple databases. CAL -SITES: Formerly known as ASPIS, this database contains both known and potential hazardous substance sites. The source is the California Department of Toxic Substance Control. A review of the Cal -Sites list, as provided by EDR, has revealed that there is 1 Cal -Sites site within approximately 1 mile of the subject property.

The Department has determined that the Zilog facility was closed in a manner consistent with Title 22, California Administrative Code, and that said closure was certified by the facility operator and an engineer duly registered to practice in the State of California. Based on information available at this time, the Department of Health has further determined that no contamination resultingfromZilog's activities remains at the site. There are, however, small concentrations of residual contaminants of uncertain origin in the soil. The Department therefore is proposing to permit closure of the Zilcg facility, with no requirement for Zilog to pursue additional closure or post closure activities at this time. Your attention to this matter is appreciated. If you have any questions, please contact Mr. Daniel E. Murphy at (415) 540-2043.

Box 309 3000 Busch Road Pleasanton, CA 94566 Dear Mr. Bouse: Subject. Fuel Leak Investigation at Kaiser Cement, 24001 Stevens Creek Boulevard, Cupertino, CA Per our February 26, 1999, telephone conversation, I am forwarding to you a copy of the Santa Clara Valley Water District (District's) February 7, 1997, letter and additional information. The staff at California Regional Water Quality Control Board (RWQCB) closed the portion of this case that involves gasoline tanks (Upper Service Station). The remaining source areas to be addressed are listed below and documented in our enclosed letter. Please prepare and submit a work plan to define the extent of contamination in the Lower Service Station and Emergency Generator areas. TECHNICAL COMMENTS 1. There are five former source areas at this site: Lower Service Station Emergency Generator Garage Oil House Upper Service Station 2. Lower Service Station Area Prepare a work plan to define the extent of soil and groundwater pollution associated with four removed 1,000 gallon diesel tanks. Following tank removal, reportedly floating product was observed on water in the tank pit and excavated soils contained strong diesel fuel odors. Reportedly, no samples were collected from this area and the excavation was backfilled. Emergency Generator Area Define the extent of soil and groundwater pollution associated with one removed 4,000 gallon diesel tank. Following tank removal, reportedly the tank appeared undamaged with no apparent leaks, but the associated connecting lines and plumbing showed obvious leakage. Excavated soils contained diesel odors and the excavation contained product. No samples were collected and the excavation was backfilled. 4. Garage and Oil House Areas No further work is necessary. Mr. Earl Bouse 2 March 2, 1999 Upper Service Station Area No further work is necessary; The RWQCB granted closure for this area December 21, 1995. However, if you are no long utilizing the groundwater monitoring wells installed in this area, you should properly abandon them. Contact Mr, Dave Zozaya in the District's Well Services Unit, 408) 927-0710, extension 2650. It appears that three groundwater monitoring wells were installed near the existing underground storage tanks. 6. Because closure has been granted for the only gasoline tanks at your site, it is not necessary to repeat the analyses for fuel oxygenates in your next investigation. However, it will be necessary to analyze soil and groundwater samples for the gasoline additive Methyl tert-Butyl Ether (MTBE), and to report the analytical results in your data tables, as well as include the laboratory analytical results for all samples analyzed If analytical results for samples yield positive results under method 8020, we suggest you use confirmation analyses, with analytical method 8260 or comparable, to confirm the presence of MTBE at your site. A typical way of defining the extent of contamination near and in former source areas is to install soil borings and to collect soil and groundwater samples for analysis, at depth intervals of 5 feet and at significant lithologic breaks. In order to define the vertical extent of contamination, it is necessary to collect samples until either: you reach groundwater and collect a grab groundwater sample for analysis, or obtain non-detectable analytical results for petroleum hydrocarbon contamination to a significant depth in the soil. In order to define the lateral extent of contamination, it is necessary to install borings laterally from the source areas until analytical results for samples indicate significant contaminant attenuation with distance from the source area. REQUEST Prepare a work plan to address comments 1 and 2 above, due no later than April 16, 1999. This request is made pursuant to the Regional Water Quality Control Board's authority under Section 13267 of the California Water Code.

I reduced the file size some, but it is still around 10 MB, if anyone can reduce it further without making it illegible, that would be helpful.
