Calibre provided civil engineering, planning, landscaping, and surveying services for this shopping complex at Fort Belvoir.  The 270,000 SQ FT facility was designed on a compact 25-acre site that is heavily wooded, creating a unique PX style and design finish.  The shopping center includes 9 food concepts, a military clothing sales store, and 20 service/concession activities. The new exchange features 140,000 square feet of retail space, a military clothing store, food court, florist, dry cleaners, salon and barber shop, pharmacy and optical center.
 
The goal of the site was to create a greatest value facility that utilized sustainable methodology and value engineering to produce a retail experience that captured the distinct architectural character already existing at Fort Belvoir. Included 958 parking spots (26 ADA and 100 low-emitting vehicles).
 
The site required reduced parking, partial underground detention and water quality, minimized stream impacts, and site disturbance reduction.  The project incorporated Low Impact Design Elements and LEED design elements. Services included concept and final layouts, roadway and intersection analysis, grading, storm water management, water, sewer, LID, ATFP, landscaping, hardscape, porous paving, underground detention and water quality facilities, bio-retention, design calculations, project specifications, stream/environmental permitting, NCPC exhibits, product submittals, RFIs, record drawings, and construction survey.
 
The project required coordination and permitting with: National Capital Planning Commission, State of Virginia, Army Corps of Engineers, Department of Environmental Quality, American Water and Installation.
 
The stormwater management approach for this project was complex and unique in that it incorporated a variety of controls and strategies on site to mitigate the impacts of development on both the quantity and quality the stormwater.  These included: four bio-retention areas, a mechanical filter, two fields of porous paving, two underground detention facilities and vegetated swales. Infiltration was incorporated into the various facilities where possible.  Proper design allowed required Phosphorous and Total Suspended Solids removal rates to be met or exceeded, and heat island effect was minimized to achieve LEED credit levels. Both LEED credits for Stormwater Design are being reviewed for anticipated award to the project.
