What “cleanup” should mean in Gowanus as redevelopment accelerates

Hi neighbors — I’m Mark, a local resident and sustainability researcher. I wanted to share a question that’s been on my mind as redevelopment ramps up in Gowanus: are we building on long-term containment controls without enough public transparency and enforceable accountability?

I recently published a City Limits op-ed focused on 459 Smith St., a former manufactured gas plant parcel on the canal. My goal isn’t to stop redevelopment. It’s to ask what “sustainability” should mean when new housing and public spaces are being planned in a flood-prone area shaped by legacy industrial contamination.

In plain terms, many remedies in these settings rely on things like caps, barriers, vapor systems, and long-term monitoring. Those can be appropriate tools — but they only protect people if the systems are maintained, checked, and enforced over time, and if the public can actually see what the data says.

Here’s the piece (disclosure: I’m the author):

I’d genuinely love neighbor input: what would you consider a fair “minimum standard” for long-term protection and transparency in Gowanus as redevelopment scales up? For example, is it better public reporting, clearer enforcement triggers when monitoring changes, stronger long-term accountability, or something else?
