La Jolla Crossroads
La Jolla, CA
Mixed-Use Development
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. Commercial development includes retail shops along the ground floor of the residential units. The industrial development is spread over three separate lots. Future tenants will include industrial, research and development, and scientific facilities. SB&O is the Engineer of Record for planning and civil engineering services, and Surveyor of Record for surveying services. Planning services included the processing of permits for Planned Residential Development, Planned Industrial Development, Hillside Development, and Resource Protection Ordinance; tentative subdivision map, and attendance at Community Planning Group meetings, and Planning Commission and City Council hearings. Design services included preparation of subdivision map, public and private improvement plans, grading and utility plans, traffic control plans, traffic signal plans, and Caltrans encroachment permit. Off-site improvements included the widening of La Jolla Village Drive and coordination relating to the Executive Drive undercrossing of La Jolla Village Drive. Survey services included a topographic survey, and an ALTA survey for 7 phases. Provided construction staking for the mass grading operation, infrastructure improvements, and 9 buildings (podium over parking).
- This project contained unique design characteristics related to the realignment and reconstruction of existing trunk line public sewer facilities.
- The original sewer facilities traversed the site before approximately 600,000 cubic yards of fill material were imported 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 runs in a north-south direction and an 18" sewer that runs in an east-west direction.
- These new sewer facilities were designed to withstand up to 75 feet of fill material.
- Another design challenge was the creation of a 7' x 7', 1,500-foot long, poured-in-place concrete box structure.
- This box structure traverses the site at the same elevation as the new sewer facilities and is also designed to withstand up to 75 feet of fill material.
