The act provides that provisions of expired law establishing the Missouri Downtown Rural Economic Stimulus Act (MODESA) are extended. The act allows development areas and development project areas approved under both MODESAEA and MODESA to be modified. Any debt obligations issued to carry out a development project shall be extended to thirty-five years. One hundred percent of payments in lieu of taxes and eighty-five percent of economic activity taxes generated in relation to an expanded development project shall be used each year of the approved term to support development project costs. An office displacement and retail or restaurant displacement percentage shall not apply to an expanded development project. (Section 99.1260) The act requires the Department of Economic Development to disburse the state construction income tax increment to support development project costs. Such disbursements shall cease within 180 days of the date on which the Department determines that the construction of the expanded development project is complete and has opened to the public. The Department shall disburse the residential income tax increment to support development project costs for a period not to exceed thirty-five years. The developer shall elect how to calculate the amount of such disbursement.
