Grace Industries was tasked with construct a 6,700LF flood wall around the Bay Park Sewage Treatment Plant in East Rockaway, New York to protect against storms such as Hurricane Sandy. The wall consists of a subterranean slurry wall extending 25’ below sea level as well as a combination of concrete walls and earthen levee berms that reach 17’ above sea level. Grace self-performed the concrete and earth work for the flood protection wall, installed all of the new drainage in the plant that is designed to prevent backflow during a flood, and restored the overflow channel that protects the plant from overloading should the sewage plant’s facilities fail. In addition to the flood wall, the contract entails the demolition and restoration of three parks adjacent to the plant; featuring two turf fields, basketball, handball, volleyball, and tennis courts, and a dog walk park. The work also included replacing and upgrading many of the underground utilities servicing the plant and surrounding community.
