Queens West Development Corporation

Location: Long Island City, NY | Date: 2014

SPR represents Queens West Development Corporation (QWDC), a subsidiary of New York State's Empire State Development (ESD), in connection with New York's largest mixed use public-private development. During the early planning stages of this major initiative to redevelop a 74-acre area of the Long Island City waterfront, the firm provided environmental and land use counsel to the Urban Development Corporation (now d/b/a ESD) in connection with development of the General Project Plan and the environmental impact statement (EIS) process. It subsequently represented ESD in successfully defeating litigation challenging the adequacy of the EIS. The firm has handled all waterfront permitting issues for the development of parks and the waterfront esplanade, which involved obtaining permits from the U.S. Army Corps of Engineers and New York State Department of Environmental Conservation and other agencies.

The firm represented QWDC over CERCLA action for response costs and settled. The firm assists in connection with all aspects of remediation of legacy contamination from the area's long and varied industrial uses, including remedies under auspices of either the State's Voluntary Cleanup Program or the Brownfield Cleanup Program, recently representing QWDC in a case over response costs. The litigation recently settled.
