The Alvarado Trunk Sewer SDP project is located within the Navajo and College Community Planning Areas within Council Districts 7 and 9, respectively. The project alignment generally follows I-8 from Fairmount Ave to the city of San Diego/La Mesa border on Alvarado Rd west of 70th St. The project will impact portions of the following streets: Fairmount Ave, Mission Gorge Rd, Zephyr Lane, Adobe Falls Rd, and Alvarado Rd.
The project requires a site development permit for encroachment into Environmentally Sensitive Lands (Sensitive biological Resources) and proposes to replace approx 5.0 mi of gravity trunk sewer via open trench and trenchless construction methods. The average depth of open-trench construction is approx 20 ft. Trenchless methods include slip-lining and micro-tunneling. Average depths of the jacking and receiving pits for trenchless construction are approx 19 and 26 ft, respectively. The project will also abandon 1.6 miles of existing sewer main.
