This project proposes to rehabilitate approximately 43,030 LF of existing sewer main with trenchless technology. The project also includes: excavation to point repair 48 segments of existing main prior to rehabilitation; rehabilitation of 25 existing manholes (no excavation); repair of 7 manholes (no excavation); excavation to replace-in-place 16 existing sewer manholes; excavation to construct 46 new cleanouts (5-10 feet deep); and rehabilitation of existing sewer laterals (no excavation). Excavation will occur within previously disturbed and improved right -of-way. Excavation within easements will occur within previously disturbed soil. There shall be no disturbance of sensitive vegetation. The southernmost sections of Chollas Py and Salta PI. And Boyce Ln. involve work immediately adjacent to the MHPA and would require conformance with the MHPA Land Use Adjacency Guidelines, specifically, construction will occur outside of the breeding season from between February and the end of September.
