Document Title
Crafton Hills Reservoir Expansion Project
Document Type
SIR - Supplemental EIR
Present Land Use
PLU: Planned Development. The proposed pipeline is located in both the unincorporated County and the City of Redlands. The County land use designation is Open Space and the zoning is Flood Control.
Document Description
The proposed project would enlarge the Crafton Hills Reservoir from a useable storage capacity of 85 acre-feet to approximately 225 acre-feet. The reservoir would be enlarged by constructing a new earth dam in the adjoining drainage to the west of the existing reservoir. A ridge seperates the existing reservoir from the drainage; a notch in the ridge would be excavated to serve as a connecting channel between the existing reservoir and proposed enlargement area. Two new maintenance roads, cut slopes, and operational dam equipment also would be installed onsite. In addition, a one-half mile segment of a 48 inch diameter pipeline would be constructed to connect the East Branch Extension pipeline to the Yucaipa Pipeline. The connector pipeline would divert imported water that otherwise would flow into Crafton Hills Reservoir to the Yucaipa Pipeline during the project construction period. The connector pipeline would allow DWR to maintain water deliveries to the East Branch Extension pipeline below the Crafton Hills Reservoir while the reservoir is being enlarged. After the proposed project is completed, the connector pipeline would remain in place to provide operational flexibility in the event of a reservoir outage.
