The City of Oak Park, Michigan is having to pay a sizeable settlement in the settlement of a class action alleging that the city mischarged residents for water and sewer services. The complaint alleged that two components of the city’s charges are unfair: a Kuhn Facility debt service charge and a storm water disposal charge. According to the complaint, these charges were for a revenue-raising purpose rather than a regulatory purpose, and they did not reflect the city’s actual costs of providing the services. The complaint said that they were illegal under the Headlee Amendment to the state’s constitution. As part of the settlement, the city will pursue claims against Oakland County for overcharges for storm water disposal and assign those claims to the class and will recalculate its own charges so that the Kuhn Facility debt servicing charge is no longer a component of its water and sewer rates.
