Brownfields Program

The City of Tucson is currently accepting projects for the Brownfields environmental assessment grant program

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.
Examples of historical uses associated with brownfields sites include:
• Automotive Businesses • Salvage/Junk Yards
• Gas Stations • Manufacturing Plants
• Dry Cleaners • Photography Studios
• Storage Lots • Motels
• Trailer Parks • Abandoned Buildings
• Neighboring properties that may be negatively impacted by one of these sites
