Represents locations by overlay zone, in Prince George's County, Maryland, approved for large-scaled, planned and complete community development and includes the provision of a procedure for addressing future development and use of land in the zone. The features of this featureclass were extracted from the zoning layer as part of the migration to ArcGIS 9.1 Geodatabase in 2006-07, and now exist in separate featureclasses for their POLY, LINE, and ANNO features. This feature is usually superimposed over underlying zones in the areas designated for its use. Attributes of this featureclass are coded under the Field Name "CLASS", and theonly valid entry value to this field is "R-P-C". The historic lineage for the layer is: The Zoning Map of the Maryland-Washington Regional District in Prince George's County, Maryland dated November 29, 1949, with subsequent amendments manually drafted to 1:2400 scale WSSC grid based half sheet Mylars as annotations. WSSC grid based half sheets captured in GIS as whole sheets at 1:2400 scale in an ArcInfo library, in 1997 by CENTECH Group Inc., with the zoning layer as a second polygon attribute item named Zoning2 which was coded to "R-P-C". Subsequent amendments were incorporated. Data migration 2006-07, to ArcGIS 9.1 geodatabase and a SDE seamless Res_Planned_Community_Poly layer with subsequent amendments was created by extracting those features from the previous zoning layer. The data was captured at a reference scale of 1:2400.
