Historical Plat Maps

Through a partnership between Washington County and the Washington County Historical Society, historic plat books were scanned, cataloged and are available to search and view on-line at no charge. For a small fee, full size copies are available; please visit the Register of Deeds office.

Following the link for a given plat book will bring up a list of the pages available for that year. All pages are in .pdf format and require the free Adobe Reader to view.
