The Department of Homeland Security (DHS) has implemented a new Federal Flood Risk Management Standard (FFRMS). This standard is designed to improve the flood resilience of communities facing growing flood risks due to climate change and other environmental factors.
Here are the key takeaways for those involved in infrastructure and construction projects:
- Future-Proofing Projects: FFRMS requires considering not just current flood risks, but also those projected for the future based on climate science. This means buildings and infrastructure will need to be built to withstand higher floodwaters and wider floodplains.
- Increased Protection: The standard raises the minimum flood elevation and expands the designated floodplain area for FEMA-funded projects. This will offer greater protection for critical infrastructure like hospitals, fire stations, and facilities storing hazardous materials.
- Minimal Cost Increase: While incorporating flood resilience measures may slightly raise project costs (estimated at around 2%), FEMA will cover a significant portion of the implementation costs (often 75% or more). Long-term savings from avoided flood damage are also expected to outweigh the initial increase.
- Focus on Sustainability: FFRMS encourages the use of natural features and nature-based solutions for flood mitigation. This can include preserving wetlands, using bioswales, or restoring natural floodplains.
Effective Date and Applicability:
The final rule takes effect on September 9, 2024. It applies to all FEMA-funded construction projects, substantial improvements, and repairs to existing structures initiated after this date.
