North San Bernardino Channel

The San Bernardino County Flood Control District proposes to construct the North San Bernardino Channel Project, which would include the construction of an 8-foot-high reinforced concrete rectangular ultimate channel to replace the existing rural, interim channel and three street crossings/culverts, as well as the relocation of various utilities (primarily at the street crossings). While the final design could incorporate a soft bottom, the impact analysis under CEQA conservatively assumes a hard-bottom channel for a worst-case assessment of environmental impacts until the design is finalized. The existing channel was constructed in the 1950s and intended to be a temporary flood control channel designed to provide flood protection for a 25-year storm event upstream and a 10-year storm event downstream. The proposed improvements aim to increase flood protection to a uniform 100-year storm event protection, enhance protection for areas within the 100-year floodplain, and mitigate flooding risks for nearly 300 structures and over 200,000 residents. The Proposed Project is located within the North San Bernardino Channel (formerly known as Devil Creek Channel) north of Kendall Drive, from Western Avenue to Little Mountain Basin (approximately 1 mile), in primarily the City of San Bernardino, San Bernardino County.
