Document Description
The St. Johns Canyon Channel was constructed in 1999 as an element for the Metropolitan Water District of Southern California (Metropolitan) Diamond Valley Lake East Dam. It was designed to capture storm water runoff and to protect Goodhart Canyon Detention Basin from flooding. Recent development within tributary areas upstream of Metropolitan's property has increased storm runoff. The concrete channel has eroded as a result of storm runoff, which has created voids on the underside of the concrete lining. In some locations, the concrete lining has cracked and has displaced sufficiently to require replacement. Prompt repairs are warranted to arrest the degradation of the lining. Metropolitan proposes to repair final design for repair of erosion damage at St. Johns Canyon Channel.
