Place: Prince George Co. and Charles Co., MD

Description
Abstract 
Areas that extend one half mile beyond the Mt_Vernon_Viewshed_Poly layer. The Area of Primary Concern represents an area potentially visible from George Washington's Mount Vernon Estate (East Lawn), with the removal of forest cover and construction of buildings 36 feet high. The original analysis was performed by EDAW, Inc. in 1991 using GIS visual simulation, and was adjusted in 2007 by Michael G. Clarke, AICP using ArcView and 1:24,000 USGS topographic maps, enhanced by National Geographic (TOPO series). The accuracy of the Area of Primary Concern diminishes as the distance increases from Mt. Vernon. Field verification is required to confirm whether specific locations are within Mt. Vernon's viewshed.

Purpose 
This layer contains areas that extend one half mile beyond the Mt. Vernon Area of Primary Viewshed Concern boundaries. A buffer was created based on the Mt_Vernon_Viewshed_Poly layer.
