Additional Information

Since this is a reconnaissance-level survey, site-specific evaluations are still necessary prior to any development of resources, especially in regards to aggregate quality or environmental review. Factors such as ownership, zoning, protected waters and wetlands, environmental permitting, and other individual site characteristics are not part of the geologic resource assessment.

*The Metropolitan Area was mapped by the Minnesota Geological Survey and Metropolitan Council. More information on Twin Cities Aggregate Resources.
