Why Public Leaders Use Michigan Geological Survey Data
Public decisions about land use, infrastructure, water, energy, and environmental protection depend on what lies beneath the surface. When subsurface conditions are poorly understood, projects face delays, cost overruns, and unexpected risks.
The Michigan Geological Survey provides trusted, unbiased geologic science that public administrators can rely on to make informed, defensible decisions — before problems arise.
Reduce Project Risk
Identify geological constraints early to avoid costly surprises during construction or redevelopment.
Protect Drinking Water
Understand groundwater systems, recharge areas, and contamination pathways.
Support Smarter Land-Use Planning
Inform zoning, siting, and growth decisions with subsurface data.
Strengthen Permitting & Review
Use science-based information that stands up to public and legal scrutiny.
Save Time and Taxpayer Dollars
Leverage existing data instead of duplicating studies or reacting after problems occur.
Plan for Long-Term Resilience
Support decisions related to flooding, erosion, energy development, and climate impacts.
