Parcel Maps

The parcel map database is developed and maintained to provide current Parcel information. Land records and subdivision plats are used to make maps showing land ownership and public roads. The parcel map database is also the foundation for the Geographic Information System (GIS). Parcel information can be seen on the Washington County GIS Property Viewer.  Half-Section and Eighth-Section maps are available on the Data Map.

This data set should be used for reference purposes only. 

Washington County is not responsible for any inaccuracies, or any misuse, or any misinterpretation of the information.
