Environmental Services Engineering & Technical Support (ES/E&TS) has developed a stand alone Geographic Information System (GIS)-based database for tracking the City's environmental permits. This environmental management system (eCATS) went online in June 2000.


Brownfields are abandoned, idled, or under-used property where expansion or redevelopment is complicated by real or perceived contamination. The land may be contaminated by hazardous waste or pollution but can be reused once the land has been thoroughly cleaned up. The Brownfields Program in Tucson seeks to reclaim these brownfields to redevelop them into productive private or public property for re-use.
