LACFCD manages a flood control system of dams, reservoirs, and debris basins that are designed to collect sediment from the hillsides and prevent it from damaging property downstream. The proposed project proposes to acquire and use United Rock Quarry No. 3 as a new sediment placement site (to be called Buena Vista SPS), which would allow the LACFCD to prolong its sediment management capabilities into the future. The Project would involve the use of Quarry No. 3 as a permanent placement location for sediment removed from the District's reservoirs, debris basins, spreading grounds, and other facilities. The Project would include a project construction phase and a project operations phase. Construction activities would include necessary improvements to the Quarry No. 3 site, the Buena Vista Spreading Basin site, and the surrounding vicinity to enable trucks to dispose of material in the new Buena Vista SPS. The District would begin project construction in 2019 and Project operation in 2020. Placement of sediment at Buena Vista SPS would last approx. 50 years; therefore, the anticipated end date of the Project's operation would be in the year 2070.
