Revise procedure laws for county zoning boundary and regulation changes

This bill requires Montana county commissioners to follow specific procedures when changing zoning boundaries or regulations, directly affecting county officials and residents within affected areas. Key provisions mandate that public hearing notices be mailed to all residents with known addresses 15 to 45 days before the hearing, in addition to being posted in public locations and published in local newspapers. The legislation also establishes a 30-day comment period after the hearing for property owners to submit written feedback before any zoning changes are finalized. These changes update existing state law to ensure broader public notification and participation in the zoning decision-making process.
