Comprehensive flood risk assessment
Analysis identified 72 facilities considered at-risk to damaging water levels from potential storm surges and rainfall sources.
Economic risk modeling to protect critical infrastructure from future flooding
Hampton Roads Sanitation District (HRSD) faces severe flooding vulnerability from land subsidence, rising sea levels and intensifying storms. To future-proof its systems, HRSD worked to analyze current and future flood exposure through the year 2100.
Economic risk quantification
A FEMA-accepted benefit-cost methodology quantified flood risk in dollar terms, enhancing efficient decision-making.
Optimized capital investment schedule
Multi-objective optimization was used to evaluate over 1 million possible capital improvement schedules for 57 facilities.
Tailored mitigation solutions
Teams evaluated resilient actions and the cost implications associated, helping to inform HRSD’s capital planning process.
Equipped with actionable climate science, HRSD has identified solutions to protect its facilities over the next 80 years to address the complex, multimillion dollar risk posed by current and future flood exposure. HRSD will implement flood resilience projects as necessary to protect its at-risk facilities, allowing the utility to save and invest for the future with the confidence to make risk-based decisions.
