First of it’s kind in North Carolina; a Floodgate system is being constructed on an opening in existing levee parallel to Interstate I-95. The “levee-protected” zone of the City of Lumberton was flooded twice in a two-year period during Hurricanes Matthew (2016) and Florence (2018). Finding a more permanent solution to manage excess stormwater and closing the opening in the levee system, instead of the current sandbagging protocol, has long been a desire of the City. In partnership with the State of North Carolina and funded by a private foundation, the City, the Federal Highway Administration, and the CSX railroad came together to address this repetitive flood problem. The City retained AtkinsRéalis, serving as the Engineer-of Record to design a flood prevention closure at a CSX railroad underpass at Interstate I-95, which is a critical point of vulnerability. This ‘one-of-a-kind’ project in coastal North Carolina will help make the community resilient by providing protection to repeated flooding. Recognizing the importance of partnerships and the roles of partners from the beginning was key to success. For example, the land ownership by the North Carolina Department of Transportation and the Federal Highway Administration was addressed early on in the design phase. The design is primarily funded by federal and foundation grants and involves multiple state and federal agencies, including FEMA, the NRCS, and the US Army Corps of Engineers due to the existing levee system and citywide structural and non-structural measures to mitigate flooding that were required. In addition to the engineering design of the floodgate system, the presentation will focus on the roles of the various partners and how the design effort is managed to address the partner requirements, address how emergency preparedness is built into the gate operations, and how funding was secured to construct the project. The presentation will provide updates to the planning, design, permitting, funding, and construction aspects of floodgate project and other flood resiliency initiatives around the community.
