Revise local planning board laws

This bill amends Montana law to revise how county planning boards are composed and who can serve on them. It requires that at least one member of a county planning board be a representative from a conservation district or state cooperative grazing district, provided that person lives in the county. Additionally, if a city or town gains representation on the planning board, its council must appoint the additional members. The changes directly affect county commissioners, conservation district officials, and local government representatives by establishing new membership requirements for planning boards.
