*La Jolla Crossroads - 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.

Scope of Services
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 topographic survey, ALTA survey, and construction staking.

Challenges & Achievements
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.

Engineer of work for (approximate) 1.2 mile extension of major super-elevated roadway connecting an existing terminus at the Santee City limits to the intersection of Riverford Road and Riverside Drive. The project corridor, adjacent to the floodplain limits of the San Diego River, is unimproved, and the completion of this segment of roadway will connect a key link in the regional transportation plan. 82? of roadbed with bike lanes and 102? of right-of-way was proposed for the ultimate roadway configuration. The plans prepared provided for an interim paved width of 42?.

A new traffic signal at the intersection of Riverford Road and Riverside Drive was designed to accommodate the interim and ultimate roadway configurations to minimize traffic signal modifications in the future. Drainage systems within the public right-of-way were located in their ultimate roadway locations and modified to provide drainage for interim conditions. The new roadway''s close proximity to the San Diego River resulted in the need for one major drainage facility. This facility, consisting of a double 12? x 4? RCB, riprap and grass-lined channels which provides drainage for a 400-acre basin with a discharge of 600 cfs. Roadway striping, signing, traffic control, detouring, specifications and detailed construction cost estimates were also provided.

A separate set of right-of-way dedication drawings were prepared for the acquisition of 77 separate parcels involving 23 individual land owners. The parcels were for road right of way, slope and drainage easements, and temporary construction easements. Research of record maps, deeds and right-of-way dedications was necessary for the calculation of new parcels, areas and final deed writing for easements and acquisitions. This project involved extensive coordination with the County of San Diego Real Property Department and their title company, and the City of Santee for all facets of design. A value engineering review was conducted at the 30% review stage. Recommendations from the review were incorporated into the design.

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.
