*La Jolla Crossroads, Sewer Facilities - La Jolla, CA

Description

The project is high-density mixed-use residential and industrial development located at the southwest corner of Interstate 805 and La Jolla Village Drive. The project site covers 33.8 acres and has a density of 44 dwelling units per acre. Residential development consists of nine 5-story buildings (for a total of 1,500 units) each with a 2-story subterranean parking garage. There is a total of approximately 2,500 subterranean parking spaces, and additional surface street parking. The industrial development is spread over three separate lots. Future tenants will include industrial, research and development, and scientific facilities. This project contained unique design characteristics relative to the realignment and reconstruction of the existing trunk line public sewer facilities which traversed the site prior to the importation of approximately 600,000 cubic yards of fill material required to bring the project to its current grades. Special consideration was given to the design of the realigned facilities which include a 72” PLRCP sewer that traverses the site in a north-south direction, and an 18” sewer that traverses the site in an east-west direction. These new facilities were designed to withstand up to 75 feet of fill material. Another design challenge was the design of a 7’ X 7’, 1,500 foot long, poured-in-place concrete box structure which traverses the site at the same elevation as the new sewer facilities, capable of withstanding up to 75 feet of fill material.
