New analysis reveals FEMA's flood risk maps significantly underestimated the danger at Texas's Camp Mystic, where over two dozen died in recent floods. Data from First Street shows far more structures were in high-risk flood zones than FEMA reported, highlighting a nationwide issue. Outdated FEMA maps, often neglecting flash floods and rainfall, leave many unaware of risks, hindering preparedness and insurance access. Special interests and funding limitations hinder map updates, with consequences tragically illustrated at Camp Mystic, where buildings were located in designated floodways. Experts stress the need for improved mapping and proactive measures based on current scientific understanding.
