Bill No. 647 amends various sections of the Oklahoma Statutes related to municipal procedures, particularly focusing on zoning decisions, appeals, and the approval of plats and subdivisions. Key changes include the requirement for protests against proposed zoning changes to be filed by the owners of 20% or more of the affected area, as well as a stipulation that such changes require a three-fourths vote from larger governing bodies or a three-fifths vote from smaller ones. The bill also emphasizes that decisions on land use applications should be based on objective and relevant facts rather than solely on public opposition. Additionally, it establishes that municipal zoning decisions are valid unless proven otherwise by the challenging party.

Further amendments clarify the appeal process for decisions made by the board of adjustment, including the conditions under which a stay can be imposed during an appeal. The bill also outlines the responsibilities of the planning commission regarding the approval of subdivision plans and the criteria for such approvals. Notably, it states that compliance with comprehensive plans is not a requirement for plat approval, and in cases of denial, the basis for the decision must be recorded. The act is set to take effect on November 1, 2025.
