Cactus Basin 3 & 3A Flood Control Facility Enhancements Project

Cactus Basin 3 & 3A Flood Control Facility Enhancements Project

In 1988, the City of Rialto previously prepared an EIR for the construction of three retention basins and a segment of a flood control channel (Rialto Channel), collectively termed the Upper Cactus Bains. The original 1988 EIR was prepared for a project described as the construction of three unlined retention basins (Basins A, B and C); a rectangular concrete channel approximately 3,450 feet in length from the south side of Highland Avenue to Basin C (the most downstream basin); and a system of basin inlets and outlets. In 2006, none of the improvements had been constructed, however sand and gravel excavation work, as approved in the 1988 EIR, has been conducted on all three basins. The San Bernardino County Flood Control District is now moving forward to enhance a portion of this flood control system evaluated in the 1988 EIR. The proposed project is to increase the capacity of Basins 3 and 3A (previously named Basin C). The original stated objective is still valid, which was to eliminate any potential increase in flood hazard due to planned development in the northern portions of the City, and to help alleviate stress on other storm water facilities located downstream of the proposed project in order to allow the regional flood control system to function more effectively.
