Then municipal officials and a joint review board made up of representatives from local taxing bodies must review a plan for the redevelopment of the TIF area. Then a public hearing is held where residents and other interested parties can express their thoughts on the subject.Then the proposal must pass through the same process any other ordinance passes through approval by the municipal governing board. Then the mayor or village president will sign the ordinance into law. No state or federal approval is required.
