PROJECT DESCRIPTION PROJECT LOCATION The Dredged Material Management Site (DMMS) is located near the western bayfront of the City of San Leandro in the vicinity of Roberts Landing (see Tigure 1). The DMMS is bordered on the west and southwest by the Monarch Bay Golf Club (formerly Tony Lema Golf Course). San Francisco Bay is located beyond the golf course to the west of the project site. Estudillo Canal, a flood control channel that drains into the Bay and is managed by the Alameda County Flood Control and Water Conservation District, is located to the north of the site; the Marina Faire residential area is located beyond the canal to the northwest; and industrial and commercial uses are located across the canal to the northeast. Land owned by the State Lands Commission is located to the southwesC of the DMMS and the Citation Homes Central, Inc. residential development is located to the southeast. The Southern Pacific Railroad and the Marina Vista residential development are located to the east of the project site (see Figure 2). The 100-acre DMMS currently consists of two enclosed basins where dredged material from the San Leandro Marina and entrance channel is periodically deposited and dried. The West Basin (Basin 1), in the western portion of the DMMS, consists of approximately 37 acres and the East Basin (Basin 2) encompasses the remainder of the site. The DMMS is surrounded by levees and contains four existing weirs through the northern levee along Estudillo Canal and one internal weir. These weirs control decant drainage. A central levee, running roughly south to north, divides the DMMS into the two basins described above, with a "training" levee further dividing the East Basin. A tidal weir is present in the southern levee of the West Basin. This weir enables tidal waters from the adjacent Shoreline Marshlands Enhancement Project to enter the DMMS, once the deposited sediments in the West Basin are removed. PURPOSE OF THE PROTECT In compliance with Regional Water Quality Control Board (RWQCB) Order Nu. 90-013 and upon subsequent direction from RWQCB, the City plans to remove dredged materials recently placed at the DMMS during maintenance dredging in 2001 of the San Leandro Marina entrance channel and the San Leandro Marina yacht club and fuel dock areas. The Management Plan for the DMMS specifies that the site should be managed for the overall purpose of further enhancing its value as shorebird habitat consistent with its primary function of dredged material storage. More specifically, the Management Plan provides for "minimizing the adverse impacts to the wetland habitat values of the site consistent with dredged material handling by planning dredging projects to impact the smallest area of the site and by drying the dredged material in the least amount of time and area." In addition, the plan provides for: • seasonal and/or muted tidal water areas suitable for shorebird use, including establishment of an invertebrate food source in the water areas.
