Additional Information

Since this is a reconnaissance-level survey, site-specific evaluations are still necessary prior to any development of the 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.
