Brownfield

A brownfield is property whose redevelopment or reuse is complicated by the presence or potential presence of contamination — the umbrella term for land carrying an industrial or commercial past into its next use. The status is factual rather than formal: a lot is a brownfield because of what is (or may be) in its ground, whether or not it is enrolled in any cleanup program.

The programs exist to move such land back into use: the state's cleanup program pairs remediation standards with incentives, and the city runs its own lighter-touch track. For analysis, brownfield questions surface through records — historical uses, tanks, spills, designations — and through the diligence conventions (the site-assessment sequence) that exist precisely because ground conditions do not appear in title.
