Water Main Replacement - Acacia Avenue to Starr Tank
MND - Mitigated Negative Declaration
Present Land Use
Multiple Species Conservation Program habitat Preserve as well as light residential neighborhoods/REP, R110P, PC & RR/Chula Vista-Quasi-Public (Open Space Preserve) and Residential low density (zero to three dwelling units per acre [du/acre]) San Diego County-Rural Residential (two du/acre)
Sweetwater Authority proposes to replace approximately 1,255 linear feet (LF) of existing 10-inch welded steel water main with 120inch Fusible Polyvinyl Chloride (FPVC) pipeline within an easement between Acacia Avenue and the Starr Tank Site. The access area and staging areas total approximately 1.1 acres. In order to avoid habitat impacts, directional drilling would be employed for the pipeline replacement and would be installed in three separates runs or "borings". Run 1 requires a bore pit (approximately 1 ½ feet wide, 4 feet deep and 5 feet long) located in Acacia Avenue right-of-way, and a receiving pit of the same size located in a temporary 700-square-foot construction pad. The total directional bore length for Run 1 would be approximately 700 LF. Run 2 would also require a bore pit equal in size for Run 1 located adjacent to Receiving Pit 1. The total directional bone length for Run 2 would be approximately 255 LF. Run 3 requires a boring pit (boring pit 3) to be located at the southeast corner of the Starr Tank site and would utilize Receiving Pit 2 at the 90-degree angle where the pipelines connect. The 12-inch FPVC pipelines would be joined together by open trench construction within the two temporary construction areas.
