ASTORIA — The city is looking for public input on its Brooklyn-Queens streetcar proposal, and will hold a series of "community visioning sessions" in the coming months to get feedback from the waterfront neighborhoods that would be served by the rail line.

The Economic Development Corporation and Department of Transportation will host the first community meeting from 6 to 8 p.m. on May 9 at the Variety Boys and Girls Club, located at 21-12 30th Rd. in Astoria, city officials said.

It'll be followed by other meetings over the next three months in neighborhoods like Long Island City, Greenpoint, Williamsburg, DUMBO, Brooklyn Heights, Cobble Hill, Red Hook and Sunset Park, officials said, with exact dates to be announced soon.

The sessions will let residents weigh in on the Brooklyn-Queens Connector, a plan for a 16-mile streetcar on the boroughs' waterfronts that Mayor Bill de Blasio endorsed during his State of the City speech in January.

The route would serve neighborhoods along the East River from Astoria all the way down to Sunset Park, officials have said.

The city released an early assessment of the plan this week, which estimates the streetcar would cost about $31.5 million a year to maintain and operate.
