Santa Clara Westside Storm Retention Basin Desilting Project
MND - Mitigated Negative Declaration
Present Land Use
GP: Parks/Open Space
The project proposes to excavate sediment from the Westside Storm Retention Basin to restore the basin to its original water depth of three feet and storage/holding capacity of 15.3 acre-feet. The basin currently has a water depth of 1.5 to three feet at its deepest point, a storage/holding capacity of six acre-feet, and between 1.5 and 3.5 feet of sediment accumulated on the bottom of the basin. The project would remove approximately 15,000 cubic yards of sediment. The average thickness of the sediment to be removed is approximately 1.8 feet and is as much as four feet in some areas at the edge of the basin. The depth of the basin would be increased to three feet upon project completion.
