Document Description
The project includes four principal elements: 1) Extract ~12 million tons of aggregate material for commercial use. The surface mine would operate over a 10-year period, with 8 years of active mining. 2) Implement a Reclamation Plan for mined lands to be reclaimed to a usable condition for beneficial alternate end uses. End uses proposed include habitat creation/restoration and a recreational/equestrian trail network. Public access would be made available during and after mining activities have ceased. 3) Implement a Restoration Plan which creates additional natural upland and riparian habitat types in the project area. This would be done in accordance with a County "Revegetation Plan" that would establish native wetland and upland habitat in excess of habitat mitigation requirements and of the Reclamation Plan. 4) Provide a new permanent drought-proof water supply for the District. This would be achieved by construction and operation of a groundwater recharge and recovery operation. Up to 5,000 acre-feet per year (AFY) of highly purified recycled water would be recharged into the aquifer for storage. The water would be extracted from the aquifer through wells for potable use.
