77 A site-specific Phase I Environmental Site Assessment has been prepared for the 847 Woodside Road project component (Phase I Environmental Site Assessment Report, Redwood Chapel, 847 Woodside Road, Redwood City, San Mateo County, California; Phase I Assessments; August 17, 2019) (Phase I ESA). The project component site currently contains two funeral service buildings that were constructed in the late 1950s. Prior to the construction of the existing onsite buildings, the project component site was vacant. Since the development of the existing buildings in the late 1950s, the project component site has always been used for funeral chapel services (Phase I ESA pp. 13- 14). The Phase I ESA was conducted pursuant to the requirements of the American Society for Testing and Materials (ASTM) Standard 1527-13 and the United States Environmental Protection Agency's (USEPA) Resource Conservation and Recovery Act (RCRA) Facility Assessment for corrective action. Phase I Assessments conducted a review of regulatory agency records, interviews, and a site inspection of the project component site to determine the presence, or lack thereof, of any Recognized Environmental Conditions (REC) at the project component site. According to the ASTM, a Recognized Environmental Condition (REC) is the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: 1) due to any release to the environment, 2) under conditions indicative of a release to the environment; or 3) under conditions that pose a material threat of a future release to the environment. The Phase I ESA concluded there is no evidence of historical or existing RECs at the site and recommended no additional investigation at the time the Phase I ESA report was prepared (p. 23). The Phase I ESA also evaluated the potential for non-ASTM environmental issues, including radon, asbestos- containing materials (ACMs), lead-based paint (LBP), naturally occurring asbestos (NOA), and vapor migration, to impact the project component. There is no evidence of radon gas detected at levels of concern (greater than 4.0 pCi/L) in Redwood City per the Phase I ESA (p. 11). There is a low probability of asbestos-containing rocks occurring at the project component site according to mapping produced by the California Geologic Survey, and no asbestos stone was observed at the project component site during an August 16, 2019 site inspection (p. 12). Due to the age of the onsite buildings, there is the potential that ACMs and LBP are present in the existing onsite buildings. The Phase I ESA concluded an asbestos survey adhering to Asbestos Hazard Emergency Response Act (AHERA) sampling protocol should be performed prior to demolition or renovation activities that may disturb suspected ACMs, and construction activities that disturb materials or paints containing any amount of lead may be subject to certain requirements of the Occupational Safety and Health Administration (OSHA) lead standard contained in 29 CFR 1910.1025 and 1926.62 (p. 12). Lastly, the Phase I ESA determined there is no need to assess possible project component operational air quality impacts from vapor intrusion pathways because there is no potential groundwater or subsurface soil contamination recorded within the project component site boundaries (p. 21). Current Condition Report (Phase II ESA) A site-specific Current Condition Report has been prepared for the 847 Woodside Road project component (Current Condition Report, Redwood Chapel, 847 Woodside Road, Redwood City, San Mateo County, California; Phase I Assessments; October 11, 2019) (Current Condition Report). The purpose of the Current Condition Report was to collect seven to eight soil sample at depths of 20 feet below ground surface (bgs) in the project component site’s parking area and locations near existing buildings to evaluate the subsurface soil conditions of the project component site (Current Condition Report, p. 3). While the Phase I ESA prepared for the project component (August 17, 2019) identified no Recognized Environmental Conditions at the site, the Phase I ESA report author recommended a Current Condition Report to determine the existing condition of the site’s subsurface soils (p. 3). As part of the Phase I ESA, soil samples were collected and analyzed for total petroleum hydrocarbons (TPH) gasoline, heavy metals (CAM 17), and volatile organic compounds (VOCs) based on applicable State and Federal regulations. Because contamination was documented in the soil samples in the Phase I ESA, further investigation was recommended to evaluate the vertical and lateral extent of impact. Soil samples from seven borings were collected on September 26, 2019 and compared to the California Department of Toxic Substances Control’s (DTSC) Recommended Screening Levels for Residential Soil and/or United States Environment Protection Agency’s (EPA) Regional Screening Levels for Residential Soil, both dated April 2019. The soil sample test results dated October 7, 2019 revealed no detected TPH gasoline or VOCs; recorded values for heavy metals (CAM 17) did not exceed the threshold for action based on the applicable screening levels. Based on these findings, the Phase II ESA determined no further action is required at this time for new development of residential units on the project component site (p. 14). Conclusion As stated in the Focused GPU EIR, while residential and mixed-use housing do not cause or contribute substantially to potential hazards to the public or the environment, it is possible that, during construction activities, contaminants in soil or groundwater could expose future construction workers, residents, workers, or other members of the public to potential hazards (p. 4.9-20).
