The Green Bay Transit System is owned and operated by the City of Green Bay. Service is provided to the City of De Pere, Village of Allouez, and Village of Ashwaubenon under cost sharing service agreements. The purpose of this study is to analyze the current transit cost sharing formulas between Green Bay and the urban municipalities in terms of both operating and capital expenditures. The study report includes a detailed analysis of federal, state, and local operating and capital funding formulas and expenditures for the Green Bay Transit System from the 1974 public takeover to 1986. A survey of medium-sized public transit systems in Wisconsin was conducted in terms of local cost sharing formulas and service contracts. Study recommendations include a new depreciation "surcharge" for capital expenditures and written service contracts between Green Bay and the other municipalities.
