With so many county communities bordering parkland, it is not surprising that park neighbors occasionally enter into activities that go beyond their property lines. Encroachments are illegal, are punishable by law, and can take many forms:
Encroachments damage park resources. Piles of yard waste may introduce destructive, invasive plants into natural areas. Removal of trees and other foliage decreases the vegetative cover that filters pollutants from the air and modifies temperatures. Removal of natural ground vegetation encourages erosion and allows surface run-off to contaminate water sources. Digging and removal of artifacts on undeveloped land destroys the integrity of archaeological and historic sites. Extending yards, storing material and equipment, and erecting private fences or other structures on parkland effectively limits access to acres of public land by fellow citizens.
The Fairfax County Park Authority was established in 1950. As the county has grown over the years, so has the Park Authority, which now holds over 23,300 acres of land. It is our mission and responsibility to provide recreational opportunities and to preserve and protect the natural and cultural resources on parkland for the enjoyment of all residents.
Approximately two-thirds of our land holdings are undeveloped natural meadows and woodlands which we maintain in a natural state. Natural vegetation cleans the air, supports wildlife, protects the water quality in our streams, and provides a cooling effect that offsets heat generated from traffic and urban centers. Preservation of these natural areas is an important priority and is vital for air quality.
Much of the undeveloped parkland is in stream valley parks. Stream valleys are the park system’s connective web, providing wildlife habitat and travel corridors, linear green space, trail opportunities and watershed protection. Each stream valley serves its watershed as a drainage route leading to the Potomac River and, ultimately, to the Chesapeake Bay.
As the largest land owner in the county, it is especially important that we protect and preserve the land, both for the benefit and enjoyment of all county residents and the protection of our watersheds.
Often a property owner will purchase a home next to parkland only to discover years later that there was a pre-existing encroachment that was not disclosed at the time of sale. Please contact us so that we can work with you to correct it. Park Authority staff must work within policy guidelines when addressing encroachments on parkland; however, we will provide information and help resolve the issue and prevent potential difficulties when you sell your property.
Together we can reduce the incidence and impact of encroachments on parkland. Although Park Authority staff routinely check for encroachment violations, it is simply not possible to monitor all Park Authority property on a daily basis. We rely on neighbors like you to help us preserve and protect natural and cultural resources by looking for and reporting suspected cases of encroachment. If you see an encroachment in progress or are aware of an existing encroachment, please contact us.
