West Magnesia Canyon Channel, City of Rancho Mirage, Riverside County, California. Detailed Project Report. RANCHO MIRAGE, Flood Control. Main Report and EIS (Environmental Impact Statement) with Public Involvement and Environmental Appendixes

Book excerpt: West Magnesia Spring Canyon Creek, which originates in the Santa Rosa mountains, skirts the western side of Rancho Mirage along the foothills as it leaves the canyon and flows a distance of about 1.5 miles before it empties into the Whitewater River. The drainage basin comprises about 5 square miles. The main objectives of this study are to provide a high degree of flood protection to the residents of Rancho Mirage and to protect the Nation's environment. The Corps recommends that, subject to certain conditions of non-Federal cooperation as outlined in this report, the proposal for flood control be approved for construction. The total cost of the recommended plan is estimated at $8,279,000. The Federal share of the estimated cost would be $4,000,000, and the non-Federal share would be $4,279,000 of which $3,891,000 is for construction and $388,000 is for lands, easements, rights-of-way and relocations. The local sponsor of the project is the Coachella Valley Water District. (Author).
