Portions of the subject segment of the Coachella Valley Stormwater Channel (CVSC) were found to be inadequate to convey the 100-year and the Standard Project Flood. The proposed project will include modifications to the existing channel and the possible 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 Avenue 58, within the unincorporated community of Thermal, Riverside County, CA. Improvements may include but are not limited to channel widening, concrete-lined banks, lowering of the invert of the Thermal Drop Structure, and construction of additional conveyance facilities.
