1. Introduction <br />GHD Inc. (GHD) was retained by the City of San Leandro (City) to perform a Decommissioning and <br />Demolition Study for the San Leandro Marina (Project) located at 40 Mulford Point Drive, San <br />Leandro, California. A site plan showing the San Leandro Marina and limits of work is shown on <br />Figure 2. This Study presents a general overview of project plans and includes discussions of the <br />decommissioning and demolition strategy and methods, cost estimates and a summary of relevant <br />environmental regulations and permits required for the work. <br />1.1 Project Objectives <br />The goal of the Project is to decommission and remove all marina infrastructure from the harbor <br />basin, which includes the removal of the 462 berths. In conjunction with the proposed Shoreline <br />Development project, the harbor basin will instead become an area for human-powered watercraft <br />and recreation and allow interaction with San Francisco Bay without removal of sediments from the <br />harbor basin. <br />1.2 Background <br />The San Leandro Marina has operated since the 1960s as a small boat basin and has <br />approximately 25 percent of the 462 berths currently occupied. The Federal Channel leading <br />into/out of the harbor received a partial dredge in late 2009, but the harbor basin itself has not been <br />fully dredged since 1997, and there is no near-term funding identified to dredge it. A previous <br />Alternatives Study for the Harbor Basin developed alternative configurations to retain aquatic <br />recreational opportunities and mesh with existing and potential landside uses. Following the study, <br />the City Council directed staff to move forward with a plan for closure of the Marina, to be <br />implemented at such time that siltation accumulation precluded vessel movement into/out of the <br />basin and/or funding for maintenance work could not be allocated. The San Leandro Shoreline <br />Development Project contemplates, in part, decommissioning and removal of the existing <br />motorized vessel facilities and appurtenances in the harbor basin to allow for passive recreational <br />uses. The project would require removal of structures and features including the timber and <br />concrete docks and associated piers, restrooms, fuel dock (decommissioned), Harbor Master’s <br />office, remnants of the Blue Dolphin restaurant platform, and rip-rap in select locations. The Marina <br />Decommissioning and Demolition Plan is focused on only waterside features of the project which <br />will be removed and either recycled, reused, sold or disposed. <br />1.3 Project Location <br />The San Leandro Marina is generally located on the east shore of the San Francisco Bay between <br />the City of Oakland to the north and the City of Hayward to the south as illustrated in Figure 1. The <br />redevelopment would include the Harbor Basin (which would be undertaken by the City) as well as <br />the surrounding shoreline areas (which would be undertaken by a private developer). <br />17
