Title: Otay Valley Quarry Reclamation Plan Amendment EIR
Description: The Otay Valley Quarry Reclamation Plan Amendment project proposes the reclamation of 197 acres within the 278-acre project site following the completion of mining activities at the Otay Valley Quarry. Reclamation would involve preparing the surfaces to a condition suitable for subsequent development and/or open space in accordance with the P-C zone and the Chula Vista General Plan. Surfaces would be stabilized for erosion control. Cut surfaces would be completed to slope grades to ensure long-term stability. Sediment basins and fines storage areas would be dewatered and revegetated with plant species suitable for erosion control. Grading would be completed in such a manner as to ensure proper surface drainage. Recoverable topsoil would be stockpiled for use on benches and quarry floor areas to be revegetated. The soil would be placed to enhance revegetation as surfaces are completed. The success of revegetation would be monitored after completion of final reclamation to ensure successful erosion control. The quarry pit area would hold local groundwater, creating a water body with approximately 80 acres of surface area.
