Document Description
The Alameda County Flood Control and Water Conservation District (District) proposes to repair the eroding creek bank along Line F-1 downstream of Sycamore Street in the city of Newark, Alameda County. Over the years, high velocity flows have been eroding this section on the west bank. Approximately 65 linear foot (LF) section has eroded along the western bank. The eroded area would be backfilled with approximately 290 cubic yards (CY) of imported soils, compacted, and reinforced. Approximately 150 tons of rock slope protection (RSP) will be placed along the toe of the slope extending 3’ up the bank, and planted with willow live cuttings to further stabilize the eroded areas and provide additional protection from future erosion. A temporary cofferdam and bypass would be created to keep the work area dewatered during construction. All disturbed areas will be restored by hand broadcasting with a local seed mix. The purpose of the project is to repair the eroding creek bank, minimize future erosion, and improve flood control protection to the surrounding community. All work will be phased to take place during the summer months to minimize any impacts.
