Boca Quarry Expansion Project
Document Type
EIR - Draft EIR
Present Land Use
Existing mining operation (proposed expansion), FR-160-ME (Zoning), FOR-1 60 (General Plan)

Document Description
The proposed project would expand existing mining operations in the currently permitted Boca Quarry (U06-012). The application includes an Amended Use Permit (Ull-008) as well as a Reclamation Plan modification (RPll-001) to correspond with the proposed mine expansion and the importation of clean fill material for pit backfilling. The proposed project would increase the allowable extraction/disturbance area by approximately 118 acres in the area referred to as the West Pit for a total area of approximately 158 acres (ultimate disturbed area) which would increase the maximum annual production to one million tons. The proposed Conditional Use Permit (Ull 008) envisions the removal of 17 million tons (approximately 13 million cubic yards) of material in three phases over a 30 year period. Off-site roadway improvements are proposed in an improvement area consisting of approximately 22-acres along Stampede Meadows Road.
