• Dominion Valley Commercial Center – Market Square

• Spotsylvania Town Centre Expansion
  Spotsylvania County, Virginia
  Site plan for the addition of a lifestyle center (6 buildings totaling about 190,000 sq.ft.) as well as a future cinema, restaurant and hotel. This plan required extensive relocation of existing utilities, new utilities and underground SWM/BMP facility (approximately 12 acres). Grading required within the FHWA I-95 right of way was a major challenge for the site.

  Town of Herndon, Virginia
  Herndon Habor House is an elderly, independent-living facility located in the Town of Herndon, Va. This development entails two - 3 story buildings located on approximately 2 acres.  The total number of residential units is 60.  RDA provided the boundary and topography surveys as well as the complete project site design.  In addition, all plats were prepared (including a condominium plat) by RDA.  Close coordination with the town was also necessary to assure that the project was in substantial conformance with the original approved rezoning.
