Environmental Information Management System (EIMS)

The Environmental Information Management System (EIMS) is a system for providing timely and reliable information for environmental planning and decision-making for the Twin Cities Metropolitan Area (TCMA) of Minneapolis and St. Paul, Minnesota. Metropolitan Council Environmental Services (MCES), a division of the Metropolitan Council, developed the EIMS to provide access to environmental data, analysis, and documents from various sources through a single, integrated system. The Metropolitan Council is the regional planning agency serving the TCMA and providing essential services to the region.
