ARCDBA.Zoning_Poly

The location of permitted uses by Class of Zone for property located in Prince George's County, Maryland.

Represents the locations of legally determined permitted uses for properties located in Prince George's County, whose zoning is governed by the decisions of the County Council, sitting as the District Council as was delegated to them by the State of Maryland. Uses are determined by Classes of Zone as cited in the Zoning Ordinance of Prince George's County, Maryland, Subtitle 27.

Zoning boundaries at rights-of-way are graphically delineated to follow property boundaries that run along those rights-of-way; however, in accordance with Zoning Ordinance, Sec. 27-111. Boundaries of zones, permitted uses should always, unless explicitly cited, be interpreted to follow the centerlines of those rights-of-way.

Polygons of this featureclass represent regions of like zoning unbroken by parcel boundaries. Varying uses and conditions between adjacent properties with like zones are distinguished by annotations found in the "Zoning_Anno" featureclass and by the boundaries delineated in the "Zoning_Line" featureclass. 

Classes of Zone are attributed to this featureclass under the Field Name "CLASS", using the same abbreviated format as appears in the Zoning Ordinance, Sec. 27-109, except in the case of the "M-U-TC" zone which due to set field widths available at the time of its original creation was coded to "MU-TC"instead.

The featureclass is comprised of six Subtypes each having a single domain that is set to the Default Value and contains the number of Classes as reflected in the table below. The Subtypes are attributed to the featureclass under the Field Name "ZONE_TYPE" using the same abbreviated format as appears in the Zoning Ordinance, Sec. 27-109.

As part of the migration to ArcGIS in 2006-07 the "R-P-C" (Planned Community Zone) which is one of the zones cited  under Classes of Zones, Sec. 27-109 of the Zoning Ordinance, was extracted out of zoning and its features were captured separately, and can now be found in the Res_Planned_Community featureclasses for POLY, LINE and ANNO under the Zoning featuredataset.

*The R-P-C Zone by definition of the Zoning Ordinance (Subtitle 27) is classified under the category  Planned Community; however it is now handled for GIS purposes only in new separate featureclasses for the POLY, LINE and ANNO features related to this Class of Zoning.

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.

- 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 subsequent amendments incorporated.

- Data migration 2006-07, to ArcGIS 9.1 geodatabase and a SDE seamless Zoning_Poly layer with subsequent amendments incorporated. The data was captured at a reference scale of 1:2400.
