Technical Description:

  • (2) UrbanPond® Concrete Detention System
  • (1) Modular Wetlands Linear® Bioretention System

Jaguar Land Rover constructed its largest luxury dealership in the county across the street from the Marine Corps Air Station Miramar in San Diego, California. The new 2.9-acre dealership will have a 48,000-square-foot building and a fleet of first-class cars. Due to the sheer size of the building, the first hurdle was designing an efficient infrastructure and a stormwater system for the limited footprint.

The dealership includes a large parking structure, showroom, and maintenance facility within a small footprint and along a busy thoroughfare. The footprint is further reduced by the depth of the existing drainage system, which will be connected to the new system. In addition to storage, the site needed to address water quality, and the entire system needed to be traffic rated and placed under drive aisles.

To meet these challenges, engineers at TAIT & Associates designed a stormwater management system with two UrbanPond modular detention systems with a Modular Wetlands Linear treatment system placed downstream to meet the required treatment goals. Engineers designed the UrbanPond systems with 6 feet inside height modules, and both units contain interior walls for separating hydromodification, direct capture volume, and outlet controls. A standard box culvert was initially proposed for storage, but the UrbanPond gave the designers more flexibility to accommodate the building’s footprint, landscaping, and interior chamber requirements.

The two storage systems sit on opposing sides of the main building. On the west side, the UrbanPond is comprised of 48 modules, while the east has 121 modules. Both storage units flow downstream to a single 4’x8’ Modular Wetlands Linear, creating a hydraulically connected treatment train for optimal performance. All three units are traffic rated and were placed below the driveway and parking areas.
