Document Description
The Santa Clarita Valley Water Agency (SCV Water) adopted the Final IS-MND for the Sand Canyon Sewer Relocation Project on October 1, 2024. As originally proposed, the project includes construction of approximately 3,500 feet of 21-inch and 15-inch sewer pipeline along the north side of the Santa Clara River. The goal is to move the existing sewer line out of the river's flow path and into the adjacent overbank, and the project would involve abandoning the existing sewer line in place. The eastern end of the new sewer line will be within Sand Canyon Road, terminating near existing commercial areas, while the western end will connect to the existing line west of Mitchell Hill. The project will temporarily impact an area of about 104,000 square feet. Additionally, the project includes a 12-foot paved access road and bank protection for the new sewer line, with two 16-foot-wide bridges over drainage features. The bank protection will consist of an 8-foot-wide soil cement section with varied height, and the adjacent bed will be vegetated with native species.
SCV Water now proposes modifications to the Original Project, referred to as the “Modified Project.” The Modified Project includes an expansion of the project site, minor modifications and adjustments to the access road/multipurpose trail alignment, minor modifications and adjustments to the soil cement bank protection to include rock slope protection in three locations, the removal of the exposed portions of nine manholes from within the Santa Clara River channel, and new access routes from the southern bank of the Santa Clara River to the manhole locations.
SCV Water has prepared an Addendum to the Final IS-MND for the Sand Canyon Sewer Relocation Project, and determined that the Modified Project would not result in a new significant environmental effect, or a substantial increase in the severity of previously identified effects.
