The Problem With Calling Them 100-Year Floods
The misleading term describes a devastating event that happens more often than you might think
The solution: Build smarter and don’t let new development make flooding worse.
Adjust guidelines to plan for bigger events. Preparing for a flood that has a 1 in 10,000 chance of happening each year will protect areas from rare but destructive floods, as well as those that are deceptively common (like 100-year floods).
Update floodplain maps to accurately reflect the changing levels of flood risk due to changing environmental conditions.
Communicate flood risk in a way that is more easily understood.
The next step: Flood-prone communities should ask their elected officials to move to a higher development standard. Keeping outdated standards is unacceptable as flooding continues to worsen.
