HB 5577 Michigan House · 2025-2026 Regular Session

Land use: other; coordinate systems; update. Amends secs. 1, 1a, 3, 4, 6, 7, 8 & 9 of 1964 PA 9 (MCL 54.231 et seq.) & repeals secs. 2, 5 & 5a of 1964 PA 9 (MCL 54.232 et seq.).

HB 5577 updates Michigan's official land survey coordinate systems to align with current national standards. It formally names and defines the "Michigan plane coordinate system" (MCS 27 for 1927 coordinates and MCS 83 for 1983 coordinates), divides the state into north, central, and south zones based on specific counties, and sets requirements for documenting coordinates (including units, metadata, and positional tolerance estimates). The bill directly affects land surveyors, government agencies, and property recorders who use these systems to define land boundaries. It standardizes how coordinates must be reported in surveys and land records to ensure accuracy and consistency with national geodetic networks.

MODERATE
This bill updates Michigan's coordinate system laws to modernize how land positions are defined and recorded. It formally adopts the Michigan Coordinate System of 1983 alongside the older 1927 system, establishes specific geographic zones (North, Central, South) for mapping, and adds strict requirements for metadata and accuracy when recording land surveys. The legislation also clarifies legal conflicts between coordinate descriptions and traditional public land survey references.
Scope change
The bill expands the scope of the State Plane Coordinate Act to include the modern Michigan Coordinate System of 1983 and explicitly defines the state into three distinct geographic zones for coordinate application.
DEFINITION

New definitions were added for 'Coordinates', 'FGCC', 'Metadata', 'Michigan plane coordinate system', 'NOAA/NGS', 'NSRS', and 'Zone' to clarify technical terms used in land surveying.

REQUIREMENT

New requirements mandate that recorded land surveys must include an estimated standard deviation of positional accuracy and a description of the nearest geodetic control monument used.

New rules require that if a land tract crosses coordinate zones, the specific zone used for reference must be named in the description and identified in the metadata.

The law was modified to state that coordinate descriptions are supplemental to traditional public land survey descriptions, with the traditional survey descriptions prevailing in case of conflict.

TIMELINE

A timeline was established prohibiting the use of the Michigan Coordinate System of 1927 after December 31, 1989, designating the 1983 system as the sole system thereafter.

TECHNICAL

Outdated text and formatting artifacts from the original introduction were removed to streamline the legislation.
