BROOKLYN - Plans to develop the old Domino Sugar factory in Williamsburg into waterfront housing may be in jeopardy.

Mayor Bill de Blasio is insisting the developers add more affordable housing units.

Two Trees Management Company developers say plans for the 2,300 housing units already include 660 affordable housing units.

The company has already had its plans approved by the local community board, and the City Planning Commission is expected to vote on them this Wednesday.

If approved, developers say it will take six to eight years to build the development, which will also include offices and 5 acres of green space.
