New York, NY —

A Katrina-sized hurricane could put the city out of commission.

That's what scientists and infrastructure experts told the City Council's Infrastructure Task Force yesterday.

The city's Office of Long Term Planning says it's working on a strategic plan and reaching out to vulnerable communities. Deputy Director Ariella Maron says it's a first-ever initiative, but it's not easy.

MARON: You want to talk about something long-term, but you want to address their immediate concerns. You want to talk to them about adaptation, but at the same time to let them know there's things they can do to reduce their carbon impact right now.

REPORTER: Pilot workshops have been held in Sunset Park, Broad Channel and the northern end of Staten Island.

More are planned for the more than 50 communities in the city's coastal plain.
