National Park Service – Sandy Hook WWTP and Maintenance Facility

Located in Gateway National Recreation Area, Sandy Hook National Park is a destination for outdoor recreation and tourists of nearby historic landmarks such as Fort Hancock Historic Post and the Sandy Hook lighthouses. Along with other park structures, the maintenance facilities and wastewater treatment plant (WWTP) were damaged by flooding during Superstorm Sandy in October 2012. After initial emergency repairs, the client was determined to undertake a long-term solution to upgrade the existing facilities and make them more sustainable. The damaged WWTP was replaced by a new packaged treatment system above the flood elevation. Construction had to be closely coordinated and phased to maintain operations at the existing plant until the new system was fully online.

Several existing maintenance buildings were replaced with a new, consolidated facility built within the Fort Hancock Historic Post Area. 360 provided mechanical and plumbing system design for the entire project, which included an adaptive reuse of two buildings into primarily storage and office space, construction of a new vehicle/equipment maintenance and repair shop; improvements to site access, parking, and circulation; and updates for adequate vehicle/equipment and materials storage and perimeter security.
