Remonumentation PROGRAM


The Macomb County Remonumentation Program, established in 1992, embarked on a schedule of replacing, restoring and maintaining all public land survey monuments in Macomb County. These monuments are used by Land Surveyors to determine property line boundaries, road alignments, subdivision layouts, as well as, the location of commercial and industrial property.

The Remonumentation Program is funded 100 percent by the State of Michigan, Department of Licensing and Regulatory Affairs. The program began as a 20 year effort to survey the State of Michigan; however, the time allotment has been extended until January 2023. The Maintenance Program will take effect after January 2023. This program will preserve the efforts realized in the Remonumentation Program by ensuring the monuments remain in their proper location.

The first and last survey of the State was commissioned in 1815, and took approximately 40 years to complete. Original markers were 4-foot long wooden posts. Most of the original markers have been removed due to road construction and development. The wooden posts have also deteriorated over time; nonetheless, some of the original monuments have been recovered by following in the footsteps of the original surveyors and through careful excavation.

In the above photo, Roger Stecker, P.S. of Lehner Associates, Inc., set this monument (inset picture). OC-059 is a witness monument to the true Private Claim corner located over 300 feet into Lake St. Clair.
According to Martin Dunn, Macomb County Surveyor Rep, “Orderly, consistent remonumentation with standardized markers assist in the documentation and planning of roads and utilities, the location of public and private property, the settlement of ownership claims and disputes, and inclusion in a statewide central data base. This data base contains information on counties and townships throughout the State of Michigan.”

The contracted surveying firms have researched, monumented and approved a total of 2,229 GLO section corners, private claim corners and property-controlling corners in Macomb County through December 31, 2018. The surveyors have also established 93 Global Positioning System (GPS) monuments and placed State Plane Coordinate values on 1,483 corner monuments. The GPS monuments and State Plane Coordinate values placed on the corner monuments provide reference points for computerized mapping.

Three Continuous Operating Reference System (CORS) stations have been installed as well. The stations are located in the Village of New Haven, the City of Warren and Washington Township. The CORS stations are monitored by the Michigan Department of Transportation and have provided the most accurate GPS data in the world.

The 2019 Remonumentation Program will fund the research and monumentation of 43 corners and place 57 State Plane Coordinate values on corner monuments.
