200FT_Contours: Contours Reflect the elevation of areas within the County. The contours map layer is based on the United States Geological Survey (USGS) 7.5 minute Digital Elevation Model (10 meter resolution). Contour information is approximate and should not be used to determine the exact elevation of individual properties.

200ft_ContourLabels: The elevation in feet of the 200FT_Contours. 

Parcels: Parcel Boundaries - Taxlots are the divisions of land utilized by the County's Department of Assessment & Taxation for taxing purposes. The taxlots typically reflect individual property or ownership boundaries that have been determined through the recording of subdivisions, minor land partitions, and documents altering property boundaries or conveying ownership. The taxlots map layer is updated on a continuous basis with efforts made to keep it current as possible. Each taxlot is associated with a taxlot number (i.e. 270615BB00100). Taxlots are used for assessment purposes only and are not reflective of a property's legal right to be developed.
