NEW YORK (AP) - New York City Mayor Michael Bloomberg today announced a waterfront plan that calls for 50 new acres of parks and an expanded maritime industry that would make room for giant ships that are rarely seen on the East Coast.

It's the city's first waterfront plan in two decades.

Mayor Michael Bloomberg announced the plan Monday after taking aferry to Brooklyn Bridge Park.

The plan envisions a metropolis where residents fish and bike inparks, kayak in the Hudson River and commute by ferry.

The first stages of the effort are expected to cost the citymore than $3 billion over the next three years, with most of thatgoing to wastewater infrastructure.
