The INS Sector Support/ Air Operations Facility consists of four masonry and steel utility buildings (Facilities Maintenance Shop, Vehicle Maintenance Garage, Electronics Shop, and an Air Operations Facility) totaling 93,000 square feet; helipad concrete pavement totaling more than 115,000 square feet; and vehicle concrete pavement of almost 266,000 square feet.

The 30,408 SF Vehicle Maintenance Shop included secure access, gas and diesel fuel island, rinse facilities, wash rack, and utility building, truck refueling facility, and high bay maintenance areas with overhead bridge crane, and specialized systems including vehicle exhaust removal system and compressed air.

Environmental issues included the remediation of lead contaminated soils of three abandoned firing ranges on the former U. S. Navy site. Over 30,952 tons of lead contaminated soil was processed, far in excess of the RFP identified quantities.

Multiple environmental issues had delayed the planning and procurement of the project for over ten years. These included site protection of areas of endangered “Otay Mesa Tar Plant” and vernal ponds. Construction included a 900’ long by 20’ wide storm drain corridor through a Fish & Wildlife agency protected zone requiring coordination with multiple local and state agencies and a national pollutant discharge elimination system (NPDES) permitting process through the California Regional Water Quality Control Board.”
