The city is looking to expand East River waterfront access in once heavily industrial north Brooklyn by building two massive piers in Greenpoint.

The Economic Development Corp. yesterday began soliciting proposals from developers interested in building a pier at the end of Java Street on nearly 18,000 square feet of city land, much of which is submerged.

The site held a working pier decades ago, but the city dismantled it in 2000.

The pier would be two blocks from another the city plans to bring to India Street, which would provide ferry access.
