At least 120 people have died and some 173 people remain unaccounted for statewide, nearly a week after flash floods ravaged the Texas Hill Country.

Since 2016, the topic of a "flood warning system" for Kerr County has come up at 20 different county commissioners' meetings, according to minutes. The idea for a system was first introduced by Kerr County Commissioner Thomas Moser and Emergency Management Coordinator Dub Thomas in March 2016.

Kerr County, Texas, lacked a “last mile” warning mechanism that could have saved residents before the deadly floods devastated the area, including a children’s summer camp, killing more than 80 people.

"I thought my mom was going to die in front of me," said Taylor Bergmann, a 19-year-old who fought to save the people in his family after the Guadalupe River smashed through their home.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

Federal forecasters issued their first flood warning at 1:14 a.m. on July 4. Local officials haven’t shed light on when they saw the warnings or whether they saw them in time to take action.

A "Basic Plan" for emergency response for three Texas counties labeled flash flooding as having a "major" impact on public safety, according to a page on a city website.
