Document Description
Portions of the subject segment of the Coachella Valley Stormwater Channel (CVSC) are inadequate to convey the 100-Year. The proposed project will include modifications to the existing channel and the construction of additional flood control improvements to provide at least 100-year flood protection. The study area extends from Avenue 54 downstream to the Thermal Drop Structure just north of Ave 58, within the corporate limit of the City of Coachella and the unincorporated community of Thermal, Riverside County, California. Improvements include but are not limited to channel widening, concrete lined banks and channel bottom, lowering of the channel invert, removal of the Thermal Drop Structure, and relocation of the affected utilities. Please see the full project description in the attached CEQA EIR.
