Document Description
ACWD proposes to restore the hydraulic connectivity between two recharge basins, the Above Hayward Fault and the Below Hayward Fault ponds, by replacing the existing diversion pipe with a reinforced concrete box culvert and spillway. The ponds are separated by an unengineered levee that is a remnant of past quarry operations. A valve-controlled, corrugated metal pipe served as the former conduit that allowed water levels between the AHF pond and the BHF pond to be adjusted. The original pipe and valve assembly are located at the southern end of the existing levee. Failure of this pipe has led to erosion of the levee face around the pipe exit. As part of the proposed project, the district would also repair existing erosion damage on the surface of the levee and decommission the original metal pipe assembly at the southern end of the levee.
