A big new waterfront development called Rose Plaza on the River is quietly making the rounds in the land use review process. The development would be a three-building project south of Schaefer Landing in South Williamsburg, immediately north of the big power plant that Con Ed is demolishing and across the street from the 475 Kent Avenue, the building to which residents just returned. Developers are seeking R-7 zoning, which is the same as Schaefer Landing, which has 350 units in two buildings. The developer would be Waterfront Realty, which includes several veteran Brooklyn real estate players including Stanley Gallant and others. The plans have been presented to Community Board 1. Interestingly, the Brooklyn Navy Yard Development Corp. has proposed filling in much of the channel behind Rose Plaza on the River in order to accommodate development, so it could become Rose Plaza near the landfill. A full city land use review is needed because the developers need a zoning change to build anything.
