Maps of Dayton and Montgomery County

This plat map is the first in a series of maps DHBO hopes to add over the next year. The PDF file is large so as to allow a close view of the map.  Once it is downloaded you will be able to save the file to your computer and/or print it out in its entirety. As this is a first time experiment for the DHBO staff, please let us know if there are problems with the PDF file (for instance, too slow to download).

If you have a map that you would allow us to add please contact Curt Dalton at
