Fairfax County Park Authority is fortunate to own and care for several historic houses, outbuildings, and surrounding landscape, but the needs are greater than the paid labor force can provide. The HSVC is designed to provide supervised and planned attention to the minor but crucial maintenance and repairs of those facilities and grounds by a group of concerned and knowledgeable volunteers. This group also serves as a presence for these unstaffed facilities to deter vandalism and unwanted activity.
