APPROPRIATION / PHASE: General Investigation
DESCRIPTION: The New Jersey Back Bay (NJBB) Focus Area is located behind the New Jersey barrier islands of Monmouth, Ocean, Atlantic and Cape May Counties and includes the set of interconnected water bodies and coastal lakes that are separated from the Atlantic Ocean. The authority for the NJBB Study (Resolutions adopted by U.S. House of Representatives and U.S. Senate Committees in December 1987) support NACCS outcomes, are broad in scope and application and address the development of a coastal processes database, monitoring and related actions as the basis for actions and programs to prevent the harmful effects of shoreline erosion and storm damage. The authority also recommends that site specific studies for beach erosion control and hurricane protection be undertaken in areas with a Federal project, action, or response. The purpose of the study is to investigate Coastal Storm Risk Management (CSRM) strategies and solutions to reduce damages from coastal flooding affecting population, critical infrastructure, critical facilities, property, and ecosystems. The NJBB Study is being performed to align with the goals of the North Atlantic Coast Comprehensive Study (NACCS), which are to:
- Provide a risk management framework, consistent with and NOAA/ USACE Infrastructure Systems Rebuilding Principles; and
- Support resilient coastal communities and robust, sustainable coastal landscape systems, considering future sea level and climate change scenarios, to reduce risk to vulnerable populations, property, ecosystems, and infrastructure.
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; and
- If system-wide solutions are not feasible, assess the feasibility of implementing site-specific solutions, such as a combination of structural, non-structural, and natural and nature-based features.
The end product of this study will be a decision document in the form of a Chief’s Report authorizing comprehensive USACE design and construction opportunities using the full array of CSRM strategies and measures for community-based solutions within a watershed-based, systems framework. Also included in the report would be 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, as well as public-private partnership opportunities into the NACCS NJBB study umbrella. A programmatic NEPA document will be developed identifying a range of impacts. The PED Phase will include detailed design with a detailed fully compliant programmatic NEPA document which evaluates impacts for specific solutions.
Study milestones include: Tentatively Selected Plan (Jan 2020); Agency Decision (Jul 2020); Final Feas Rpt (Nov 2021); and Chiefs Report (Apr 2022).
- Flood risk is increasing for coastal populations and supporting infrastructure.
- Improved land use, wise use of floodplains, responsible evacuation planning, and strategic retreat are important and cost-effective actions.
- Communities should adopt combinations of solutions, including nonstructural, structural, natural and nature-based, and programmatic measures to manage risk, where avoidance is not possible.
- Communities must identify their acceptable level of residual risk to plan for long-term, comprehensive,and resilient risk management.
- Many opportunities exist to improve risk management, including enhancing collaboration, building new partnerships, and strengthening pre-storm planning.
- Addressing coastal risk requires collaboration among local, regional, Tribal, State and Federal entities, NGOs, academia,
- Resilience can be encouraged through the use of a CSRM framework and commitments to advance sea level and climate change science, and storm surge modeling and related themes.
