Title

Sand Canyon Sewer Relocation Project

Description

The Sand Canyon Sewer Relocation Project (hereby referred to as “proposed project” or “project”) involves the construction of approximately 3,500 linear feet of new 21-inch and 15- inch sewer pipeline along the north side of the Santa Clara River. An existing sewer line extends east from Vista Canyon Boulevard at the State Route 14 undercrossing within the Santa Clara River, crosses under the Sand Canyon Road bridge, and terminates approximately 600 feet east of the bridge. The purpose of the proposed project is to relocate the existing sewer line from within the flow path of the Santa Clara River into the adjacent overbank. The existing sewer line would be abandoned in place. The easternmost end of the proposed sewer line would be located within Sand Canyon Road, and would terminate east of Sand Canyon Road near existing commercial uses. The westernmost end of the sewer line would connect to the existing sewer line west of Mitchell Hill. The project's temporary impact area totals approximately 104,000 square feet. The proposed project also includes a 12-foot paved access road and bank protection for the proposed sewer line. The access road would generally overlap the new pipeline but would deviate from the proposed alignment where jack-and-bore construction is proposed. The access road would also include the installation of two 16-foot-wide bridges across existing drainage features. Proposed bank protection would consist of an 8-foot wide soil cement section with a varied height. The soil cement bank protection would be exposed, and the bed adjacent to the soil cement would be vegetated with native species.
