DIMENSIONS: How accurate are the parcel lines on the Parcel Viewer?

The parcel lines on our GIS maps and internet mapping platforms are for reference purposes only and may not accurately reflect the actual location of parcel boundaries.  Some lines are relatively accurate, while others may be off 20 feet or more. While the DID is actively working to improve the accuracy of the parcel lines to +/-3 feet, this is a very big project and will take many years to complete.  When in doubt, always contact a private surveyor.
