Title

Alvarado Trunk Sewer

Description

Site Development Permit to allow for the replacement and/or re-alignment of approximately 5,031 linear feet (LF) or (0.95 miles) of sewer main pipelines. Existing 8-inch to 18-inch vitrified clay sewer pipes would be replaced with 8-inch and 21-inch polyvinyl chloride (PVC) pipe and centrifugally cast-fiberglass reinforced-polymer mortar (CCFRPM) pipe. Approximately 4,431 LF of the sewer pipelines would be located in new trench alignment at approximately 7 to 51 feet deep and 600 LF of sewer pipe would be in the same trench at a shallower depth of 12 to 21 feet deep. Approximately 3,373 LF of pipe installation work would be performed by conventional excavation (open trench) method, and 1,662 LF of pipe installation would be performed by tunneling method.
