Contaminated properties, Superfund sites, brownfields, and landfills are often located within flood hazard zones and may have been designed without consideration for long-term challenges from climate change and sea level rise. When impacted by natural disaster, particularly flooding, these sites can experience the uncontrolled release of polluted soil, water, and groundwater; sludge; non-aqueous phase liquids; and/or vapor. The resulting, toxic conditions pose dire risks to human health and the environment.

The environmental scientists and engineers within GZA’s Natural Hazard Risk Mitigation and Resilience group work with owners, municipalities, facility designers and operators, as well as regulatory agencies, to incorporate flood mitigation and climate change resilience into remedial design?, facility design, construction and operation.  Services include:

  • Hazard Characterization (e.g., flooding, sea level rise)  - HF asks: is this equivalent to Hazard Vulnerability Assessment?
  • Climate Change Characterization (e.g., increased precipitation intensity and frequency, saltwater intrusion, etc.)  - HF asks:  is this equivalent to Climate Change Assessment?
  • Hazard Vulnerability Assessment (e.g., erosion and sediment transport, liner deterioration and permeability effects)
  • Climate Change Sensitivity Assessment (e.g., damages to liner material, leachate collection/removal systems, landfill gas management systems, rising groundwater levels, etc.)
  • Natural Hazard Mitigation Planning
  • Climate Adaptation Planning
  • Emergency Response Planning
  • Resilience and Adaption Design
  • Regulatory Compliance Reviews
  • Preparation of Plans and Specifications
  • Resilience and Adaptation Cost Estimation
  • Benefit-Cost Analysis (BCA)
  • Mitigation Construction Management
  • Monitoring and Oversight
  • Funding Opportunity Audit
  • Federal Grant Application Preparation
