Lexington Quarry Expansion
Document Type
NOP - Notice of Preparation of a Draft EIR
Document Description
The proposed project is the expansion of the existing Lexington Quarry by 5.6 acres, for a total quarry area of 59.6 acres. The proposed expansion would require modification of the existing Use Permit for the quarry issued in 1990. Also proposed is extending operating hours to include an eight-hour day on Saturday. Lexington Quarry harvests earth materials (primarily hard graywacke sandstone), processes it on-site, and sells it to customers on a retail basis. Materials produced from the quarry site include roadbase materials and construction aggregate. The proposed project would extend quarrying to the southerly portion of the east quarry face (Figure 2). The quarry boundary under the Use Permit would also be expanded to include an existing settling basin adjacent to Limekiln Road. The proposed expansion of the quarry would yield approximately 1.8 million tons, or 1.2 million cubic yards of material. Excavation of remaining materials within the quarry (including the expansion area) would occur over a 16-17 year period, with an additional two years required for completion of quarry reclamation measures. Reclamation measures for the quarry and quarry slopes include planting quarry benches with trees and shrubs and reestablishment of a tributary creek channel through the center of the quarry.
