What do we do?
The Plat Department maintains surveys recorded in Lake County as well as the history of property transfers in plat books, filed by section, township, and range or by subdivision name.
Surveys, section maps, plats and deed exhibits can be downloaded by selecting COMMUNITY SERVICES on the top navigation bar and selecting DOWNLOADS (top of the middle column).
