Effective - 27 Jun 2000   72.423. Five-year planning cycle, procedures, map plans, review. — 1. In any county in which a boundary commission has been established pursuant to section 72.400, all boundary changes and unincorporated area proposals shall be subject to the five-year planning cycle mandated in this section. No municipality nor other person shall file, nor shall the commission accept or review, any boundary change or unincorporated area proposal which has not previously been submitted to the commission for map plan review and comment as provided in this section, except that consolidations of municipalities and transfers of jurisdiction pursuant to subdivision (2) of subsection 6 of section 72.405 may be sought at any time without prior submission for map plan review and comment as provided in this section.  2. Between January 1, 2000, and July 1, 2000, and between January first and July first of each sixth year thereafter, each municipality, the county, and any citizen group may present general maps of proposed boundary changes and proposed established unincorporated areas to the commission for map plan review. Proposed incorporations and unincorporated areas, if not submitted by the county, shall be submitted by petition of no less than five percent of the registered voters within the proposed area. Boundary change and unincorporated area maps shall not be accompanied by a plan of intent, but shall be depicted with sufficient detail and accuracy to permit review and comment.  3. Between August 1, 2000, and December 31, 2000, and each sixth year thereafter, the commission shall solicit written comments on all boundary change and established unincorporated area map plans and shall hold informational public hearings in or near the affected areas, at which the county, any municipality, or other interested person shall be heard. The commission may encourage negotiation between parties involved in competing map plans. Map plans may be amended by the submitting parties until April fifteenth of the year following map plan submission based on negotiation or based on the hearings or other comments, but no such amendment shall enlarge the boundary change or unincorporated area map plan beyond the area originally submitted, except for minor technical amendments necessary to address boundary issues.  4. The commission may by April first of the year following map plan submission issue written comments regarding each boundary change and unincorporated area map plan to notify proponents of the merits or demerits of such map plan based on planning and public policy considerations. The map plan as submitted or as amended by April fifteenth shall remain on file with the commission, and shall be the limit of permissible boundary changes and unincorporated area proposals as provided in subsection 1 of this section.  5. Proposals shall be submitted to the commission no later than July first of the third year following conclusion of map plan review. Any proposal which has not been approved by the commission by January first of the next review period year as provided in subsection 2 of this section shall expire without further action. ­­-------- (L. 1999 S.B. 160 & 82 § 20, A.L. 2000 H.B. 1967)  Effective 6-27-00
