In 1981, Fairfax County condemned about 50 acres of trees and trailers on Richmond Highway. Now, more than a quarter-century later, officials are moving forward with plans for the troublesome lot.

The property is called North Hill, part of the former Woodley Nightingale Mobile Home Park that sits atop unstable marine clay and is rife with steep topography. The surrounding community has debated for years whether to turn the property into park space or redevelop it as affordable housing after the county relocated most of the mobile homes on the site.
