EXPLANATION: Phase I and Phase II Environmental Site Assessments (EA) were prepared for the project site in March of 2001. In addition, a Bulk Asbestos Survey was also prepared in March 2001. It should be noted these assessments covered the properties indicated as 467, 505 and 517 Marina. Boulevard only (Yokota Nursery site, where the McKevitt and Batarse Trust dealerships and new public roadway would be located). This property encompasses approximately 9 acres and is improved with 21 greenhouses, three residences and several sheds and other small structures. A nursery has operated on the site since at least 1917. Pesticide used at the site may have included long-lived organochlorine pesticides, and for which residual levels may be present in the on-site soils. Initial evaluation of the on-site soils indicate that concentrations are below commercial clean-up standards. One groundwater sample did detect low levels of pesticides. Further investigation and monitoring of this well will be required. The Phase I EA indicated that the potential exists for underground fuel storage tanks to be located on the property, although no such tanks are in use by the cuaent property owner. The Asbestos Survey found asbestos-containing construction materials in the greenhouses, the boiler room, hot and cold water piping.(ninc from boiler to greenhouses), and in a building bathroom ('The residences were not surveyed, although asbestos-containing materials are anticipated to be encountered.) All asbestos materials are required to be abated prior to demolition,. which all affected buildings are proposed for demolition to make way for the new automobile dealerships. The future automobile dealerships w~71 contain service centers, which use varying quantities of listed hazardous materials (mostly petroleum based substances). Present-day use .of potentially hazardous materials is highly regulated by several agencies, including CaUOSHA and the Alameda County Fire Department, to name just two. Therefore, future use of the site with the proposed uses is not anticipated to result insignificant impacts to those working/living in the project vicinity. The following mitigation measures are recommended in order to reduce potential impacts related to pesticide contanvnation of on- site soils and groundwater wells, and asbestos-containing materials to a level of insignificance. Prior to Site Plan Review approval, the respective future property owners of the McKevitt and Batarse Trust dealerships shall submit site remediation plans for review and approval by the Regional Water Quality Control Board, the Bay Area Air Quality Management District, aid the City of San Leandro Environmental Services Manager. Remediation may include stripping the top foot of soft, tilling the top foot of soil, or•perform a risk assessment to justify no active remediation. Four known deep water wells shall be decortmrfssioned, with the cost born by the respective future property owner. Site remediatfon (or the risk assessment) shall be completed to the satisfaction of the RWQCB, BAAQMD, and the City's Environment Services Manager prior to issuance of grading permits for the respective properties. All asbestos-containing materials shall be required to be.abated by the respective future property owner(s) prior to demolition. Non-friable materials observed can be disposed of as non-hazardous waste. Worker protection, dust controls, packaging in a sealed dumpster or closed truck, and asbestos registration of the demolition contractor•shall be required in compliance with Cal/OSHA regulation 8 CCR 1529 and the California Business Code. Friable asbestos, such as the vinyl sheeting, shall be removed under full isolation abatement procedures. All thermal system insulation is classified as friable asbestos and shall be removed under Work Class T procedures in compliance with 8 CCR 1529. All asbestos removal operations shall be conducted with the oversight and approval of the Bay Area Air Quality • . Management District. • Prior to Site Plan Review approval, the respective future property owner on which the contaminated groundwater well is located shall provide further investigation, including at a minimum the installation of a monitoring well (which may .extend for 1+years, dependent upon the findings of the investigation), to the satisfaction of the Regional Water Quality Control Board and City of San Leandro Environmental Services Manager. • 'The project •area is not located within a quarter mile of an existing or proposed school, an airport over-flight zone, nor is it included in an airport laud use plan. Development of the project area would not interfere with an existing emergency response/evacuation plan. Given the urban context, potential impacts related to wildland fires are, anticipated to be less than significant. a.
