Otay Hills Quarry

Otay HillsHELIX Environmental Planning (HELIX) is managing the preparation of an Environmental Impact Report (EIR) and Environmental Impact Statement (EIS) 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. As such, a joint EIR/EIS would be prepared for this Project in cooperation with the U.S. Fish and Wildlife Service (USFWS). 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.
