Staten Island, NY
Silver Lake Park has been an integral part of Staten Island since the 19th Century. In 1971, an underground storage tank located beneath the reservoir was constructed, and at the time it was the largest underground storage tank in the world. The reservoir was discontinued for use for potable water and is now used as part of the drainage system for the tanks. The roof of the chamber is a landscaped plaza located in the park. SUPERSTRUCTURES provided investigation and design services for the control chamber of the underground storage tank. The project called for replacement of the deteriorated roof membrane and restoring slate pavers as well as repairs to stone stair treads. The firm also designed repairs for the distinctive blue glazed brick façade and addressed conditions to alleviate future deterioration.
