This layer was constructed by combining several intermediate layers which were developed in April 2010 from a database constructed several years earlier by DPZ staff. On this layer almost all features are shown as planimetric shapes. A few features are shown as 220-foot diameter circles placed as closely as possible over the center of the feature. There are also 5 linear-style features expressed as polygons. These are roads shown as 125-foot wide buffers following the centerline of the inventoried feature. All features appear only once in the layer except for Great Falls Park Historic District Park, which is split into two polygons, one for the portion in Upper Potomac Planning District and one for the portion in McLean Planning District.
