Finding a property on this map
- Click the button above and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
- Search by street address, owner or parcel ID if the search box offers those options.
- Click a lot on the map to read its attributes.
- Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
