The city is destroying warehouses at Pier 1 to make way for part of Brooklyn Bridge Park, but in an eco-friendly sort of way.

Building material from the historic warehouses will be salvaged and reused to help construct the park, according to an agreement announced August 25 by the Brooklyn Bridge Park Development Corporation (BBPDC) and the New York State Office of Parks, Recreation and Historic Preservation (OPRHP).

The Kings County Refrigerating Company constructed the National Cold Storage Warehouses at the foot of Pier 1 between 1875 and 1915, to preserve and store perishable goods. Once a busy terminal, the warehouses have not been used in 20 years.

Even so, some wood, brick, and other building materials from the warehouses remain in good condition.

BBPDC will reuse more than 70 percent of the warehouse timber, which is long leaf yellow pine, to build park benches, picnic tables and for other purposes throughout the park.

Bricks, to the tune of 10,000, and ornamental metal stars from the structures will also be saved and used in the construction of the Empire Stores complex and elsewhere in the park, which is currently under construction.

The city and state expect to finish Phase 1 work on the park by the end of this year.

“The reuse of these historic elements respects the value of the original building while moving forward with the next step in the development of the City’s green spaces,” OPRHP Commissioner Carol Ash said in a statement.

“Integrating these materials throughout Brooklyn Bridge Park, and especially in the rehabilitation of the Empire Stores, is an appropriate way to honor the industrial heritage of the Brooklyn waterfront as it is transformed into wonderful recreational resource for the next generation of New Yorkers,” she added.

Regina Myer, president of BBPDC, said the plan is another indication of the park’s commitment to green building practices.

Along with salvaged material from the warehouses, material from the reconstruction of the Willis Avenue and Roosevelt Island Bridges, and structural fill from the East River Access project will also be used at the park site.

“We thank OPRHP for their agreement to repurpose these materials for our park. Through their cooperation, we can respect an important piece of Brooklyn’s history while enhancing the overall aesthetic of the space,” Myer said. “BBPDC is committed to incorporating green building practices throughout Brooklyn Bridge Park.”
