The Michigan Department of Technology, Management and Budget provides plat maps for Michigan townships. The maps are from the State of Michigan's original surveyor notes conducted in the early 1800s. Each county map includes outlines showing the borders of the townships, the county borders and the state line.
To access the maps from the Michigan.gov home page, click State Departments, scroll down the list, and click the BTMB icon or Technology, Management and Budget. In the scrolling marquee at the bottom of the page, click the arrow, and then locate and click the Center for Shared Solutions & Technology Partnership. Type "base map by county" inside the search box, and press enter. The page loads a map of the State of Michigan. Click a county to view or download a PDF copy of the base maps.
