In the 1980’s, the Jefferson County Assessor’s office hired a man with survey and cartography skills to create a set of hand drawn maps representing the parcel ownership throughout Jefferson County. For the last 40 years these 30” x 40” plats have been hanging in the Assessor’s office and have been a valuable tool for understanding how properties fit together. These have been digitized into this collection of 184 scanned images.

These are the 11"x14" books in the assessors office which date back to the early 1900's. Prior to the digital age, these books were the primary source for visualizing land ownership.

In the early days of Jefferson County, subdivisions, records of survey, and incorporated areas of the county were required to present a plat to the County Board of Commissioners. These plats were usually hand-drawn and were recorded in this 18” x 24” bound plat book. 64 records were recorded in this book before the modern process of recording mylar documents became common. These have been scanned and documented here for convenient access.
