New Jersey Back Bays Coastal Storm Risk Management

News & Updates

The U.S. Army Corps of Engineers and the New Jersey Department of Environmental Protection hosted public meetings regarding the New Jersey Back Bays Flood Risk Management study on Sept. 12, 2018 in Ventnor City, N.J. and on Sept 13 in Toms River Township, N.J. Some of the measures that were discussed at the public meetings included structural solutions such as storm surge barriers, tide gates, levees, and floodwalls; non-structural solutions such as elevating homes; and nature-based features such as marsh restoration and the creation of living shorelines.

Draft Interim Integrated Feasibility Report/Environmental Scoping Document

The draft Interim Report/Environmental Scoping Document will be available for public comment in early 2019. This represents an opportunity to share stakeholder/public input on the study process and progress. 

Study Background

Historic storms, including Hurricane Sandy, have severely impacted the back bay communities of coastal New Jersey. The New Jersey Back Bay Study developed out of the larger North Atlantic Coast Comprehensive Study which identified nine high-risk areas on the Atlantic Coast for further in-depth analysis. The study area is located behind the New Jersey barrier islands of Monmouth, Ocean, Burlington, Atlantic and Cape May Counties and includes the set of interconnected water bodies and coastal lakes that are separated from the Atlantic Ocean. The purpose of the study is to investigate Coastal Storm Risk Management strategies and solutions to reduce damages from coastal flooding affecting population, critical infrastructure, critical facilities, property, and ecosystems. The Study will consider the full array of structural, non-structural, and natural and nature-based measures. Examples are highlighted in the below chart.

Examples of Measures Under Consideration

Storm surge barriers consist of a series of movable gates that stay open under normal conditions to let navigation and flow pass but are closed when storm surges are predicted to exceed a specific water level. This is one of several measures under consideration as part of the New Jersey Back Bays Coastal Storm Risk Management Study, a joint effort between the U.S. Army Corps of Engineers Philadelphia District and the New Jersey Department of Environmental Protection.

Study Process

The study will consider past, current, and future coastal storm risk management and resilience planning initiatives and projects underway by the USACE and other Federal, State, and local agencies. Three overarching efforts will be performed:

  • Assess the study area’s problems, opportunities and future without project conditions;
  • Assess the feasibility of implementing system-wide coastal storm risk management solutions such as policy/programmatic strategies, storm surge barriers at selected inlet entrances, or tidal gates at selected lagoon entrances;
  • Assess the feasibility of implementing site-specific perimeter solutions such as a combination of structural, non-structural, and natural and nature-based features;
  • Assess the impacts of back bay strategies and solutions on the Atlantic Coast CSRM Program towards developing recommendations within a systems context given likely future scenarios.

Also included in the report: recommendations of actionable and policy implementable items for non-USACE entities, including floodplain management, landscape architecture, hurricane evacuation plans, and Community Rating System enhancement opportunities. Additional recommendations will be provided for incorporating existing USACE and external programs, projects, plans and actions into the NJBB framework. Environmental impacts will be assessed through the National Environmental Policy Act (NEPA) processes.
