Revise urban transportation district laws

This bill updates Montana's laws governing urban transportation districts by clarifying how district boards are selected and how property can be added or removed from these districts. It requires local governments to decide whether transportation board members are elected or appointed, and if elected, establishes rules for holding public elections and filling vacancies. The bill also prohibits local governments from forcing property owners to add their land to a district as a condition of development, requires districts to maintain clear maps showing district boundaries, and allows areas that have not received direct transportation service for five years to be removed from the district without being held responsible for the district's existing debt.
