Document Description
The project consists of the removal of existing concrete headwalls and detention basins, and the installation of a below grade 36-inch drainage pipe and revegetated downstream energy dissipater. Erosion from overflow of the Black Mountain Reservoirs has created an incised gully along the western branch of the Black Mountain Access Road and threatens to expose three San Diego County Water Authority (CWA) underground 108-inch aqueducts located approximately 15 feet below grade. After installation of the 36-inch drainage pipe is complete, all previously eroded areas would be re-contoured and restored with a native upland restoration plant palette. Staging and access would remain on urban/developed habitats within the existing access road when practicable; however, unavoidable temporary impacts to native vegetation would occur during construction in order to safely access all areas within the construction footprint.
