Bay Park Perimeter Flood Protection Project Named ASCE Project of the Year
(NEW YORK, NY – May 12, 2017) – The Bay Park Perimeter Flood Wall and Berm was recently named ASCE Long Island Branch Project of the Year.
The flood protection barrier is part of a larger resiliency program that consists of a comprehensive upgrade to critical elements of the facility pertaining to flow conveyance, whereby equipment is either submersible or raised above the projected 500-year flood elevation. All secondary treatment facilities will be flood hardened, as determined by constructability and operability constraints.
The perimeter flood protection barrier was designed primarily as a vegetated berm for visual appeal, low cost and ease of constructability. In lieu of a berm in areas with property limitations, a concrete flood wall was installed. The wall incorporates features such as architectural finishes and decorative metal screen lattice gates, improving aesthetics for the surrounding community.
As part of the perimeter barrier project, improvements were made to the surrounding park facilities. The improvements included new synthetic turf athletic fields with subsurface drainage systems, sport courts, dog park, LED sports field lighting, playground area, comfort building, parking, roadway circulation, pedestrian pathways and plaza areas, green infrastructure including rain gardens, gravel subsurface drainage detention, tidal check valves, and shoreline plantings. Storm water drainage optimizes on-site detention storage and recharge capabilities, thereby improving on-site collection and drainage conditions that mitigate chronic high tide surge conditions. Design improvements raised the area footprint by approximately 3-4 feet to eliminate standing water under normal storm and tidal conditions.
The flood wall and berm are part of the Bay Park STP Hurricane Sandy Recovery Program, a partnership between Hazen and Sawyer and ARCADIS.
