Otay Hills Quarry
HELIX Environmental Planning (HELIX) is managing the preparation of an Environmental Impact Report (EIR) for a new construction aggregates extraction operation and associated activities on a 434-acre site in the unincorporated community of East Otay Mesa in San Diego County. The proposed project involves the establishment of a mineral resource recovery operation and associated activities to create construction aggregates and materials. The project includes a Specific Plan Amendment (SPA), Major Use Permit (MUP) and Reclamation Plan for the extraction and processing of construction aggregate. Implementation of the Project would also require the issuance of a Major Amendment to the Multiple Species Conservation Program (MSCP) Subarea Plan and Incidental Take Permit under Section 10(a)(1)(B) of the Federal Endangered Species Act (ESA), as amended. The project operations would take place within an approximately 110-acre impact area, with the remainder of the project site dedicated as a biological open space preserve. Major issues include land use and planning; soils, geology, and paleontology; hydrology and water quality; biological resources; cultural resources; aesthetics; traffic and circulation; noise; air quality; and hazards.
