Document Type
NOP - Notice of Preparation of a Draft EIR
Present Land Use
Surrounding area is largely rural and agricultural in character. Agriculture RRD (Resources and Rural Development)
Document Description
The applicant is proposing to expand the hard rock quarry to the west and north of the current quarry and will disturb an additional approximately 23 acres over a 20-year mining period. The material the quarry will provide include aggregate road base, subbase, drain rock, quarry fines, fill material, rip rap (rocks six inches and larger), and possibly concrete aggregates. As these materials are processed, they will be stockpiled for eventual loading and delivery. In order to proceed with the project, the applicant is requesting a Surface Mining Conditional Use Permit, and also a rezone of the parcel from RRD to an RRD-MR (Mineral Resource) Combining District. The Use Permit and the rezone will require the County to conduct environmental review for compliance with the California Environmental Quality Act (CEQA).
