| Title | Aggregate Resources for the Twin Cities Metropolitan Area, Minnesota - 1999 | |||
| Abstract | This project contains the coverages developed and used during the mapping of sand and gravel and bedrock aggregate resources in the 7-county Twin Cities metropolitan area by the Minnesota Geological Survey in 1998-99. Work on this project was supported by the Metropolitan Council of the Twin Cities. | |||
| Purpose | This project provides citizens, local government land use planners, the construction industry, and environmental groups with specific information on the location and quality of aggregate resources. This information supports long-term comprehensive planning that takes into account needed sand and gravel resources. | |||
