Problem statement

CT ~300 brownfields in state inventory~13,000 total

Project objectives Evaluate and prioritize brownfields for

redevelopment -> decouple prioritization from end use

Visualize tool in GIS platform

Brownfield Evaluation

Criteria

Environmental

Assess risk due to suspected

contamination

Smart Growth
