Title

Lower Alameda Creek Fish Restoration in Flood Control District Zone 5, Cities of Fremont and Union City, California

Description

Optimization of the existing low flow channel within the 230-foot wide flood control channel from the scour pool immediately downstream of the BART Weir to about 600 feet downstream of the UPRR crossing; modification of the RD2/Larinier fishway concrete structure; modification of existing grade control structures; modification of bridges footings in the channel ; modification of UPRR bridge footing in the channel; protect PG&E gas main channel crossing upstream of UPRR; installation of a new modified grade control structure; install boulders to improve habitat; and plant native shrubs and grasses on the new low flow channel terrace or flood plain) between the levees. The purpose of this Proposed Project is to remove migratory impediments and improve the migratory corridor below the BART Weir to allow Central California Coast steelhead and other fish movement within the flood control channel to access upstream spawning grounds. The Project will also facilitate sediment transport downstream and thereby reduce maintenance desilting of the flood control channel as required under the Corps' O&M manual.
