Economic development: tax increment financing; water resource improvement authorities; modify. Amends secs. 703, 705 & 710 of 2018 PA 57 (MCL 125.4703 et seq.).

SB 553 amends Michigan's tax increment financing (TIF) law to allow municipalities to fund water resource improvements using TIF revenues. It specifically adds projects like lake management, shoreline protection, stormwater systems, invasive species control, and public access to inland lakes or rivers to the list of eligible TIF activities. Municipalities can now create authorities within designated "water resource improvement districts" (areas near lakes, rivers, or harbors) to finance these projects through captured tax revenues. The bill clarifies definitions for terms like "water resource improvement" and "water resource improvement district" to ensure TIF funds are properly applied to environmental and public access enhancements.
