Los Angeles County Spreading Grounds/OS-1XL/Open Space
Document Description
The proposed project would consist of consolidating the existing 20 shallow recharge basins into 6 medium-depth recharge basins, which requires the removal of approximately one million cubic yards of sediment. The consolidated basins would occupy the same footprint as the existing basins. An existing concrete swale and rip-rap associated with a flow measuring station upstream of Glenoaks Boulevard, would be demolished and removed and a new trapezoidal partial flume channel would be constructed. Approximately one million cubic yards of sediment removed from the recharge basins would be removed from the site via one of two options; (1) the existing onsite sediment conveyor belt owned by Vulcan Materials Company; or (2) trucking to an offsite disposal site within two miles of the project site.
