365 Bond

OVERVIEW
Located along the Gowanus Canal, the two-acre site encompasses an entire rezoned city block that previously functioned as a Standard Oil terminal. The development of this project included the construction of a 12-story, 323,000-SF mixed-use building, a new bulkhead, and a public waterfront esplanade through the New York State Brownfield Cleanup Program with additional oversight from the United States Environmental Protection Agency (USEPA). Our environmental engineers employed a dynamic investigative and remedial approach to usher the project through construction and remediation activities, which were completed concurrently. As part of the Brownfield Cleanup Program, the client will receive significant tax credits for the remediation and development of the property, which was transformed from a neglected site into a vibrant residential community and public park.
