Trailer Park Sewer Collection System, Torres Martinez Desert Cahuilla Indians

NOTE: Joint Document consists of Mitigated Negative Declaration and Environmental Assessment. The Trailer Park Sewer Collection System project proposes the installation of a 10-inch gravity sewer pipeline, Lift Station and sewer force main pipeline that will collect sewage from the Oasis Mobile Home Park (population approximately 2,000) and Duro Mobile Home Park (population up to 6,000) and transfer the sewage to the Coachella Valley Water District (CVWD) Water Reclamation Plant No. 4 (WRP-4). The proposed pipelines will be installed within the road rights-of-way along Avenue 70, Pierce Street and Avenue 66. The gravity sewer pipeline begins at the Oasis Mobile Home Park (located on both sides of Avenue 70) and extends approximately one-quarter mile east to Pierce Street, then continues northerly along Pierce Street connecting to the Duro Mobile Home Park at Avenue 68. The gravity sewer pipeline will connect to a proposed Lift Station on a half-acre site at the northeast quadrant of Pierce Street and Avenue 68. A sewer force main pipeline will extend from the Lift Station northerly along Pierce Street to Avenue 66 and then easterly along Avenue 66 and connect to an existing 10-inch sewer force main pipeline (located along the western dike of the Coachella Valley Storm Water Channel) which ultimately connects to WRP-4. A proposed alternative route would continue the sewer force main pipeline along Pierce Street north, past Avenue 66, and connect to the existing 10-inch sewer force main located along the western dike of the Coachella Valley Storm Water Channel. The purpose of this project is to replace the existing onsite wastewater systems at the Oasis and Duro Mobile Home Parks.
