Flood Mitigation
Resiliency Program

Flood Mitigation Resiliency Program

Project Features:

• Regional wastewater treatment facility serving approximately 500,000 residents across 19 municipalities
• 85 MGD design capacity critical to public health, environmental protection, and regulatory compliance
• Facility remained operational during Superstorm Sandy (2012) due to pre-storm planning and on-site cogeneration power
• Flooding from a 12-foot storm surge caused approximately $1.2 million in facility damage, highlighting long-term vulnerability
• Potential full system failure risk estimated at $2 billion in public, environmental, and economic impacts
• Comprehensive flood mitigation strategy developed to prevent future service interruption and environmental contamination
• Construction of reinforced concrete floodwalls protecting treatment and biosolids facilities
• Installation of stormwater and effluent pumping stations to manage flood events
• Expansion of the Co-Generation Facility with additional engines to power critical systems during emergencies
• Project funded through a 90% FEMA grant, with remaining costs financed through the New Jersey Infrastructure Bank (NJIB)
• Total project value of approximately $215 million

Key Services:

• Flood damage assessment and Facilities Flood Control Report
• FEMA coordination and documentation for reimbursement and mitigation funding
• Benefit-Cost Analysis (BCA) evaluating restoration, mitigation, operational risk, and service loss
• Environmental Assessment (EA) to evaluate and mitigate impacts of proposed flood protection measures
• Property boundary and ownership surveys for floodwall alignment and access infrastructure
• Geotechnical investigations for foundation and floodwall design
• Planning, design, and permitting of flood mitigation infrastructure
• Design of reinforced concrete floodwalls, pumping stations, and supporting utilities
• Coordination with NJDEP, FEMA, U.S. Army Corps of Engineers, and local agencies
• Preparation of permits including:
  • Waterfront Development (Upland & In-Water)
  • Freshwater Wetlands
  • Flood Hazard Area
  • Section 10 / Section 404 (USACE)
  • Treatment Works Approval
  • Soil Erosion and Sediment Control
• Integration of resiliency and redundancy into critical wastewater infrastructure
• Protection of public health, regulatory compliance, and long-term system reliability
