Bay City Area Transportation Study (BCATS)

Federal law requires a continuous, cooperative, and comprehensive transportation planning process in urbanized areas with a population of more than 50,000. The flow of federal transportation dollars is dependent on the continuation of a certified planning process. The Bay County Transportation Planning Division acts as the Metropolitan Planning Organization (MPO) for the Bay City Urbanized Area and is responsible for fulfilling these duties. The Bay County Transportation Planning Division prepares required annual reports; developing the 2045 Metropolitan Transportation Plan and the 2020-21-22-23 Transportation Improvement Program; provides staff coordination for the Bay City Area Transportation Study (BCATS); and conducts various transportation studies in the community. This division also works closely with other transportation studies in the community and region throughout the year.

The Bay City Area Transportation Study (BCATS) is the principal public agency conducting regional transportation studies for the Bay City Urbanized Area. BCATS, through an agreement with the Bay County Board of Commissioners, provides management and policy functions for the transportation planning programs as required by the Fixing America’s Surface Transportation Act (FAST Act), signed by President Obama on December 4, 2015. BCATS provides transportation planning services on behalf of the metropolitan planning organization (MPO) for Bay City and Essexville and the townships of Bangor, Monitor, Hampton, Portsmouth, Kawkawlin, and Frankenlust.
