Modifies provisions relating to regional planning commissions

SB 797 modifies Missouri law governing funding for regional planning commissions. It authorizes annual state payments to legally formed commissions (like East-West Gateway and Mid-America Regional Council) from state funds, requiring a 50% local match and capping payments at $65,000 annually for the two largest commissions and $25,000 for others. The bill prohibits funding for any commission advocating for a major airport in Illinois and mandates that commissions must use proportional representation based on population (with each member jurisdiction having at least one vote). This changes how state funds are distributed, emphasizing local matching contributions and specific funding limits for different regional groups.
