DUDEK <br />Client: City of Santa Monica <br />Project Location: Santa Monica, California <br />Project Dates: 2017-2019 <br />Client Reference: Rachel Kwok, rachel.kwok@santamonica.gov, 310.458.8341 <br />Key Personnel: Glenna McMahon, Susan Smith <br />Dudek prepared a Phase I ESA for the 15.5-acre Santa Monica City Yard property as part of the due <br />diligence process for the Environmental Impact Report (EIR). The project involved proposed <br />reconstruction of the Santa Monica City Yards, which included demolition of existing buildings, <br />excavation activities, and construction of new buildings. The Phase I ESA identified RECs associated <br />with groundwater impacts from an adjacent gas station and potential presence of tetrachloroethylene in <br />deep groundwater from a regional plume. The Phase I ESA also identified a controlled REC (i.e., the <br />presence of a former landfill on the subject property) and a historical REC (i.e., former underground <br />storage tank [UST] releases). The report was prepared in accordance with ASTM Standard and the All <br />Appropriate Inquiries Rule. Dudek conducted a Phase II ESA for the project to evaluate the RECs <br />identified in a Phase I ESA. The Phase 11 ESA investigation was focused on the former aircraft/missile <br />manufacturing and leaking UST areas; additional sample points were advanced near the perimeter of <br />the property to evaluate potential impacts from the regional groundwater plume. The Phase II ESA <br />investigation consisted of a geophysical survey, and soil and soil vapor sample collection and analysis. <br />Soil samples were analyzed for metals and soil vapor samples were analyzed for gasoline range <br />organics and volatile organic compounds (VOCs). <br />Client: City of Chula Vista <br />Project Location: Chula Vista, California <br />Project Dates: 2017-2020 <br />Client Reference: Alan Reyes, areyes@chulavistaca.gov 619.407.3588 <br />Key Personnel: Glenna McMahon, Audrey Herschberger <br />Dudek evaluated a Public Works project for Conditional Exemption for the CEQA process. Dudek <br />conducted an ESA and subsequent Phase I I ESA (groundwater and soil investigation) to determine the <br />extent of impacts to the project area from adjacent contaminated sites. Following the evaluation of the <br />data collected during the Phase II ESA, Dudek prepared a Hazardous Materials Contingency Plan <br />(HMCP) detailing known impacts and outlining plans for management of contaminated materials during <br />construction process. Dudek also assisted the City with determining a process for obtaining a dewatering <br />permit. Dudek recently conducted a new Phase I ESA and revised the HMCP for the expanded project <br />area. Dudek is scheduled to conduct monitoring for the City during the construction process. <br />Various Environmental Services 8 <br />
