Kerr County alone lost 107, including more than two dozen children at Camp Mystic. From afar, it would be easy, even tempting, to think that floods like these could never happen to you. These are the same elements that could trigger a Kerr County type of catastrophe in every state in the country. “Kerr County is an extreme example of what’s happening everywhere,” said Robert Freudenberg, vice president of energy and environmental programs at the Regional Plan Association. Texas ranks seventh in the country, with about 800,000 properties, or roughly 6.5 percent of the state’s total, sitting in a flood zone.
