Land use: other; Michigan-Indiana boundary; provide for survey of parts and for grants to county remonumentation programs. Amends secs. 5, 7, 11 & 13 of 2022 PA 81 (MCL 54.315 et seq.) & repeals this act.
SB 595 authorizes the survey of specific sections of the Michigan-Indiana boundary and provides grants to Michigan counties for remonumentation programs. It directly affects counties along the Michigan-Indiana border that need to update or verify boundary markers. The bill amends existing law to establish procedures for conducting these surveys and distributing grant funds to counties for boundary marker maintenance. This is a procedural land survey and grant program bill with no direct impact on residents or businesses beyond boundary management.

MODERATE
The bill was amended to add Section 5, which establishes the Michigan-Indiana state line commission within the Department of Licensing and Regulatory Affairs and specifies the composition, appointment process, and meeting requirements for the commission. The amendment also adds Branch County and Hillsdale County to the list of counties from which commission members must be selected, expanding the geographic scope of the commission's membership requirements.
Scope change
The commission's membership requirements now include surveyors from Branch County and Hillsdale County in addition to the previously listed counties (Berrien, Cass, and St. Joseph).
REQUIREMENT
Added Section 5 establishing the commission's structure, including appointment by the governor with senate consent, 2-year terms, vacancy procedures, removal authority, meeting schedules, and quorum requirements.
ELIGIBILITY
Added Branch County and Hillsdale County to the list of counties that must have at least one commission member resident or operating in.
SCOPE
The bill now amends sections 5, 7, 11, and 13 instead of sections 7, 11, and 13, reflecting the addition of the new Section 5.
TIMELINE
The repeal effective date was changed from January 1, 2026 to January 1, 2030.
