Description: Address Points contain a single dot for each address or point of interest within the County. This feature is used as the primary despatch source in the County's E911 CAD System. The Street Address subtype includes addresses and "0" address placeholders, which represent parcels and addressed structures. If a structure is present the address point appears within the building footprint, otherwise the point is located at the geographic center of the parcel. Multiple non “0” addresses can be associated with a given parcels, where there are multiple structure and or Real Estate Cards. The Point of Interest subtype is reserved for named places and features that are not tied to a parcel. Some examples of a Point of Interest include: bridges, hazardous curves in a road, entrances to subdivisions, and mile markers. Either subtype can contain civic location, coordinate pairs in multiple projections, common name, and site type information.

Description: The Parcels feature is the geographic representation of cadastre records within the County as recorded in deeds and plats. The current parcels set is based off of the 1979 double circle maps by Wingate Appraisal & Mapping and digitized in the early 1990s. The data is continuously updated, as new land records become available. New parcels are added in a “best fit” methodology giving preference to the most current source. This feature is co-managed in AutoCAD and ArcMap. In Arc this polygon feature is part of a Editing topology along with our Zoning feature and our Administration feature. This prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.
