NEW YORK CITY-With Brooklyn’s northern end poised to become a “tech triangle” district by the city, the borough’s westerly section of Sunset Park is also evolving from a gritty seaport into a modern industrial waterfront. Helping to lead the charge are brokerage firms Cassidy Turley and Greiner-Maltz, who have been hand-picked by the New York City Economic Development Corp. to lease up the remaining 350,000 square feet of industrial space at the Brooklyn Army Terminal along the Upper New York Bay.

David Lebenstein, senior managing director at Cassidy Turley, tells GlobeSt.com that he expects the space to be completely occupied within 12 to 18 months. “That’s a realistic horizon,” he says, explaining that a variety of commercial and industrial tenants are well-suited for the location. “There’s the normal warehouse, distribution and light manufacturing users, and then there’s small-growing companies that are growing organically in Brooklyn and Queens. Greiner Maltz has their boots on the ground in Brooklyn and we will be there instantly with a presence,” he says.

The 3.1-million-square-foot complex, located at 140 58^th Street just off the Brooklyn-Queens Expressway, is 90% occupied to a mix of medical office tenants, artists and technology firms, such as DART Medical, Artistic Frame, H2K Collections, Home and Fine Arts and DJ Expressions. Sharone Levy, an executive managing director of Greiner-Maltz, will be the director of leasing for the team.
