“This site is a public park which was owned by the City of Daly City. The site will be purchased by the County of San Mateo for redevelopment as part of the Midway Village Revitalization project. The County and their non-profit real estate developer, MidPen Housing Corporation, are in the planning phase of the redevelopment process. Please see the Midway Village 41650007 Envirostor profile for additional activities related to the redevelopment. The Bayshore Park site history is described below.
The Bayshore Park site is adjacent to the PG&E Martin Service Center, the Midway Village public housing project owned by San Mateo County Housing Authority and a day care center also owned by the County of San Mateo. In the past, the site was a part of a military housing facility built during World War II by the U.S. Government. During construction of military housing, soil contaminated with manufactured gas plant residues from the PG&E property was used as fill on approximately 20 acres. This soil contained polycyclic aromatic hydrocarbons (PAHs). In 1955, the U.S. Government sold this property to the San Mateo Housing Authority. In 1977, the Housing Authority sold 10 acres to the City of Daly City. Daly City constructed the public park containing a playground and a baseball diamond. After March 31, 1979, PG&E constructed an earthen berm containing gas plant residues on PG&E Martin Service Center property along the boundary between the Martin Service Center and Bayshore Park. The berm is capped with concrete and controls storm water runoff from the PG&E property to Bayshore Park.
The Bayshore Park site is in the San Francisco Bay drainage basin and was subject to severe erosion and drainage problems. Work conducted as part of a 1999 drainage project replaced existing storm water pipes with a much larger box culvert. No reports of flooding have occurred since this work was completed.
In 2001 and 2002, a DTSC contractor excavated two feet of soil containing manufactured gas plant waste from the site. Landscape fabric and a two-foot clean soil cover were installed to provide a barrier between park users and residual waste. The property is deed restricted to prevent disturbance of the soil cover and control exposure.
