Document Description
The proposed Project will replace the previously existing concrete rectangular semi-buried Clearwell-1 and its associated pipelines and appurtenances. The Project construction area is 6.5 acres within the MWTP property immediately south of Miramar Lake and within the Scripps Miramar Ranch Community Plan area. The previously existing Clearwell-1 has been removed, and the new Clearwell-1 will be larger than the previous facility by 8.70 MG. The Project will serve both current and projected populations. The proposed new 29.5-MG Clearwell-1 reinforced concrete storage facility will be constructed with 391’ x 420’ dimensions and at approximately 26-28’ depth with hopper bottoms and a 1V:3H slope. Approximately 75% of the Project site will be graded within a 712-720-ft elevation range to slope away from the clearwells and buildings in all directions. New pole lighting will be installed. Staging for the Project will be located within the MWTP property fence line. Land adjacent to the Project site includes Miramar Lake Recreation Area to the north, Scripps Ranch Library and Miramar Ranch Elementary School to the south, and commercial, industrial and residential areas to the west.
