Searching for a parcel, step by step
- Open the link. This viewer is an ArcGIS Experience Builder app, so its layout is custom to the publisher.
- Look for a search box or search widget and type in a street address or parcel ID.
- Click a parcel to see its details in a pop-up or side panel.
- Check the toolbar for a layer list or basemap switcher if you want aerials or other layers.
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.
