Document Description
Request by CalPortland for a Conditional Use Permit (“CUP”) to expand quarry operations at their Rocky Canyon Quarry to include Phases 3, 4 and 5 as set forth in the 2002 Rocky Canyon Quarry Specific Plan (“Specific Plan”). The proposed expansion will result in an area of disturbance of about 82 acres and would enable the extraction and processing of an additional 30,843,000 cubic yards (67,854,600 tons) of aggregate which would extend the ‘life’ of the quarried products by about 57 years. The project also includes a request to amend condition No.37 of the Development Plan/Reclamation Plan to alter the design standard for interim graded slopes to reduce the bench width from 15 feet to 12.5 feet. The site consists of three lots of record with a combined area of 286.5 acres located about one mile southeast of the City of Atascadero on Rocky Canyon Road within the El Pomar/Estrella Sub-Area of the North County Planning Area. The project site is within the Agriculture and Rural Lands land use categories and is subject to the Extractive Resource Area combining designation.
