Document Description
Note: Review Period Per Lead This Initial Study analyzes the impacts of six sanitary sewer repair projects proposed by the City of Santa Clara as part of its ongoing Sanitary Sewer Condition Assessment Repairs Program. All of the proposed repair sites are located within Santa Clara City limits. Five of the proposed repairs (at Segment 23, Segments 29-31, and Segment 35) would address Grade 5 defects identified in recent condition assessments. At Segment 23, CIPP lining would be installed to address a rupture in a 10-inch-diameter VCP sewer pipe within Saratoga Avenue north of San Tomas Expressway. At Segments 29, 30, and 31, CIPP lining would be installed to repair corrosion of a 24-inch-diameter VCP sewer pipe within the parking lots at 1400 and 1390 Kifer Road and across Kifer Road at 350 Oakmead Parkway. At Segment 35, infiltration grouting would be used to repair a leaking joint in a 42-inch-diameter elliptical RCP sewer pipe extending beneath the Guadalupe River south of SR 237. Additionally, at Segment 12, CIPP lining would be installed in dual VCP siphon lines that extend beneath San Tomas Aquino Creek from the San Tomas Aquino Creek Trail on the west bank to the parking lot at 2788 San Tomas Expressway. The goal of pipe lining at Segment 12 is to prevent future problems associated with inflow and infiltration (l&I) in this segment. At all Segments, manholes would be rehabilitated as needed. The proposed repairs would incorporate extensive Avoidance and Minimization Measures to reduce potential impacts on water quality and special-status species during work near watercourses, to limit community disturbance, and to avoid community and environmental exposure to hazardous substances.
