The City of Roslyn is a National, State and Local Historic District consisting of approximately 900 property lots and 600 residential, commercial and community structures. Many structures suffer from deferred maintenance and neglect, in some cases resulting in demolition. Too often, new buildings constructed adjacent to existing structures fail to be compatible with the historic character of the town. Furthermore, the Historic District is endangered by the continuing loss of the thousands of acres of forested perimeter surrounding the town. Sales of forest land to private investors and development companies have already affected Roslyn’s historic resources. For example, a January 2009 mudslide originating from cleared forest lands above the town damaged buildings and roads. Without consideration to the town’s historic core, additional development, if unchecked, may continue to erode the historic fabric that makes Roslyn one of Washington’s truly unique and significant historic centers.
