FEMA Flood Maps Found Inadequate by New Data: NPR

New data reveals FEMA missed major flood risks at Camp Mystic. More cabins and buildings at Camp Mystic were at risk of flooding than previously reported by the federal government, according to analysis by NPR, PBS's FRONTLINE, and data scientists.

Maps by First Street show at least 17 structures in the path of flood waters, compared to FEMA's maps. The analysis also reveals at least four cabins for young campers were in an area designated by FEMA as an extreme flood hazard.

For decades, FEMA's maps have failed to consider rainfall and flash flooding, relying on data from coastal storm surges and large river flooding. First Street found that more Americans live in dangerous flood-prone areas than FEMA's maps suggest, leaving many unaware of the risk.

FEMA's maps can warn the public about danger and require precautionary measures. However, many properties affected by disasters are outside FEMA's floodplains, leading to challenges in claiming insurance and building resilience.

Special interests and political factors have hindered efforts to address the issue. Outdated FEMA maps have underestimated flood risks in various areas, including Camp Mystic.

Even when FEMA designates dangerous flood areas, warnings are not always followed. Camp Mystic has several buildings in the floodway, the most hazardous part of the floodplain.

Officials have been slow to act on flood threats in Texas, treating floodplains as red tape. Efforts to improve flood risk mapping have faced delays and challenges.

Experts emphasize the need for better decision-making based on scientific data to prepare for future catastrophes.
