Document Description
The Alameda County Flood Control and Water Conservation District is proposing to install floodwalls along approximately 1,630 linear feet of the Zone 3A, Line D channel (Ward Creek) between Huntwood Avenue and the Union Pacific Railroad tracks, and parallel to Industrial Parkway West, in Hayward, California. The proposed project is Phase II of a four-phase plan to improve channel capacity between the I-880 freeway downstream and the BART tracks upstream. Phase I consist of the construction of floodwalls constructed downstream of Huntwood Avenue along 3500 linear feet of channel, and was completed in 2011. The currently proposed floodwalls would be similar to those in the Phase I project. The concrete masonry unit floodwalls would be constructed at the top of both banks. Minor work within the channel flow line would consist of the reconstruction of four outfall structures within the channel banks to install flap gates and construction of a low flow ramp adjacent to Huntwood Avenue to allow access to the channel for maintenance. An asphalt concrete pedestrian/bike path along the southwest bank would be removed and replaced in approximately the same location at the top of the bank.
