Present Land Use
The Riverside County Integrated Plan and WCV Area Plan designate the Long Canyon and Whitewater sites as Open Space-Water, OS-Rural, Rural Desert, and OS-Conservation Habitat, the Cabazon site is within Riverside Extended Alternate Area Plan, and is designated as Rural-Mountains and Rural-Residential.

Document Description
Metropolitan is proposing two related projects to protect its Colorado River Aqueduct (CRA) Siphons from scour effects caused by erosion within the Whitewater River, and potentially at the Whitewater Mine Pit (WMP). The first is installation of large gabion mats across the CRA in the Whitewater River to provide scour protection. The second is reclamation of the WMP, which will entail excavation and trucking of materials from Long Canyon and Cabazon Spoil Sites.
