Who We Are. What We Do.


TMACOG and its partners are protecting our greatest natural resource every day. We plan for water supply and wastewater treatment in a five-county area adjacent to the western Lake Erie basin. We look at natural watersheds for the best ways to protect surface water. We work with farmers to keep land productive while keeping excess nutrients out of rivers and lakes. We help governments manage stormwater and municipal treatment facilities. And we help teachers build stewardship in the next generation.


A well-designed transportation system serves the entire community in northwest Ohio and southeast Michigan. We need it all to work together: highways and railroads, airports and city streets, bike paths and pipelines. TMACOG planners look at connections between modes, address safety issues, consider commuters, bus riders, people who use wheelchairs, semi truck drivers, and bicyclists.

Public Meetings

All TMACOG meetings and events will now be held in person unless noted otherwise. If it is a virtual meeting, the registration/login information will be posted on the events calendar at
