At a glance:   RDA provided professional civil engineering services for the Prince William County Police Department and the Northern Virginia Criminal Justice Training Academy for the development of a new Emergency Vehicle Operations Center on a site of 93 acres near the existing PWC Public Safety Training Center in Nokesville, Virginia.  The final plan included a 1.2 mile highway response course, an urban training course, an intersection training area, a skid pan and wet track, as well as a 14,000 square foot classroom training building and associated parking and utilities.  A water recycle system was designed to recapture the water pumped onto the skid pan and the wet track.  Three stormwater management facilities were designed for this site:  one enhanced extended detention dry pond, and two dry ponds.  One of the challenges of this project was to minimize impacts to the wetlands and a Dominion Power transmission easement without compromising the ability of the police to effectively conduct training exercises.  RDA has also provided professional civil engineering and surveying services for other facilities at the PWC Public Safety Training Center including master planning services, a Trench Simulator Facility, a Burn Pad for fire department training, and a shooting house for police training.
