For nearly a decade, state and local officials disacussed how to avoid fatalities, injuries, and property damage in the Guadalupe River valley in Texas. They failed to secure funds for a public warning siren. The flood killed more than 120 people and at least 160 are missing. Earlier this year, after numerous warnings by inspectors, a levee in Oregon gave way, damaging more than 950 homes, including those of the Burns Paiute Tribe. And on the Navajo Nation, notification was key to helping hundreds of residents evacuate as the Oak Ridge fire consumed more than 11,000 acres. We'll hear about those and emergency plans by some other tribes aimed at keeping threats from becoming human tragedies.
