St. Johns County Public Works Complex

St. Augustine, florida

Matthews Design Group (MDG) completed a site design to expand the St. Johns County Public Works Complex. Project scope included removal of 40,000 square-feet of existing buildings and construction of 100,000 square-feet of new building with associated parking and interconnecting roadway expansion; water distribution system design modeled for fire flow among several buildings and other locations; wastewater system design with lift station; increase to the existing stormwater pond and stormwater infrastructure; and expansion of existing site utilities infrastructure.

This project proved particularly challenging in that it required phased construction work to provide continuous operation for fleet vehicle maintenance and emergency response.
