Older buildings and neighborhoods in Fairfax County are part of Fairfax County's "heritage resources" and are economic and social investments that pay dividends. These sites and buildings also tell the history of the built environment in the county, which includes Native American hunting camps and long-term settlements, the tidewater plantations of George Washington and George Mason, Civil and Spanish-American War campsites and training grounds, as well as the 20th century planned town of Reston and its 19th century counterpart Dunn Loring. Recording, preserving, and studying this evidence enriches the quality of life in Fairfax County by putting residents in touch with their heritage, providing residents and property owners with a sense of temporal stability and continuity, and instilling in both young and old a loyalty and commitment to place and community. This public stewardship responsibility has been recognized for over thirty years and continues today.
