ONSITE CONSTRUCTION ACTIVITY Construction equipment would be used onsite to maintain roadways, move material and load trucks. Equipment would include scrapers, front loaders, backhoes, bulldozers, a water truck, and a grader (see Table 1). In addition, there could be as many as SO equipment operators and personnel at the site during construction hours. Activities would include site preparation and earthwork necessary to achieve adequate drying of the dredged material, loading of the haul trucks with front loaders and/or backhoes, and grading with bulldozers, graders andlor scrapers to achieve design elevations.

Supplemental water, in addition to precipitation, is currently made available through the Shoreline Marshlands enhancement area through a small channel and an inlet weir structure between the DMMS and the State Lands property. This inundation weir is designed to allow tidal water in, but not out, until a water depth of approximately six inches is obtained within as much of the DMMS as possible. Water is typically brought into the DMMS in December and the site is kept at least partially flooded until the following May. Optimally, the DMMS would be flooded to have water coverage over 50 percent of the site. San Leandro DMMS 9 March / 2004 Sediment Removal Nroject
