Finding a property on this map
- 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.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

Before you rely on the lines
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
