Authorizes incentives for downtown redevelopment

SB 1688 extends Missouri's Downtown Economic Stimulus Act (MODESA) to allow existing approved development projects (like those in Kansas City and St. Louis) to expand their incentives. It authorizes up to 85% of new state income and sales tax revenue generated in designated development areas to fund project costs, and extends project timelines to 35 years for tax obligations and payments in lieu of taxes. The bill removes previous requirements like displacement percentage limits and proof that projects couldn't be financed without state incentives. This directly affects developers and municipalities with approved MODESA projects that were previously unable to secure new approvals after 2013.
