House Bill No. 5287, also known as Public Act No. 26-138, introduces several technical revisions to statutes related to planning and development. Notably, it amends subsection (d) of section 7-576e by replacing the phrase "the" with "this" to clarify the designation process for tier IV municipalities, which cannot occur by any means other than those specified until April 1, 2018. Additionally, subsection (b) of section 7-576i is revised to remove the terms "tier" and "tier" before III and IV, allowing the secretary to distribute funds from the Municipal Restructuring Fund to a third party on behalf of designated tier II municipalities.

Furthermore, the bill modifies subdivision (8) of subsection (a) of section 8-13dd by inserting the phrase "as" to align the definition of "planning region" with that provided in section 4-124i. These changes are set to take effect on October 1, 2026, and aim to streamline the language and processes within the existing statutes governing municipal planning and development.
