Eagle Canyon Dam and Debris Basin Project

Eagle Canyon Dam and Debris Basin Project

The proposed project would include the construction, operation and maintenance of an earthen dam, debris catchment and underground storm drain. The project will provide flood detention and flood hazard mitigation for the developed portion of Cathedral City located downstream of the canyon. The outlet works would be ungated and the dam would, therefore, only hold water for brief periods of time following significant flood events. The debris basin would keep sediment and debris from flowing downstream and would be cleaned out on a periodic basis to prevent buildup of debris and soils. Stormwater flows from the wash would be conveyed through approximately 3300 lineal feet of 42" drainage pipeline (Line 43), which extends to East Palm Canyon Drive (Highway 111) and follows the right-of-way for approximately 1000 LF, terminating at the West Cathedral Channel, which is located southeast of Eagle Canyon next to Bankside Drive. Prior to construction of the project, the Project Proponent anticipates remediation of potentially hazardous materials resulting from illegal dumping that previously occured on the site.
