The U.S. Housing and Urban Development Department (HUD) has released a final rule requiring projects that receive HUD funding to meet the standards of resilience required by the Federal Flood Risk Management Standard (FFRMS). Under the rule, the climate-informed science approach, which considers sea level rise and rainfall, will be used to determine flood elevation and flood hazard areas. Where climate-informed science is not available, HUD will define a floodplain as an area with a .2% chance of flooding in any year or by adding 3-feet to the base flood elevation area, whichever is larger.
Below is a statement by Shana Udvardy, senior climate resilience policy analyst at the Union of Concerned Scientists.
“After many years in the making, this is the best possible standard that HUD could have issued.
“For decades, the federal government has been relying on a standard based on the past climate. This rule will change that business-as-usual practice, which wasted taxpayer dollars, put people in harm’s way and allowed for the limited affordable public housing stock to be flooded, in some cases again and again. This puts an end to that foolhardy cycle.
“As we bear witness to the increasing flood frequency from climate change-related rising tides and heavy rainfall events, this standard will help to ensure safe and resilient affordable housing. We hope this rule will be a model for federal agencies across the board.
“HUD’s standard will protect property owners, buyers, developers, and renters by requiring that they are notified of the flood risk, flood insurance requirements and options, and past insurance claims, among other critical safety information.
“I’m heartened that the rule will require HUD or other responsible entities to engage environmental justice communities during the decision-making processes and protect floodplains and wetlands that serve critical functions for communities and wildlife.”
