Organization Title

The California Geological Survey (CGS) has a project that provides objective economic-geologic expertise to assist in the protection and development of mineral resources through the land-use planning process. The project is mandated by the Surface Mining and Reclamation Act of 1975 (SMARA). The primary products are mineral land classification maps and reports. Local agencies are required to use the classification information when developing land-use plans and when making land-use decisions. The project is managed by CGS.
