A former commissioner of a flood-ravaged Texas county says a siren warning system would have saved lives and that he believes state officials will act promptly to implement a warning system.
Tom Moser, who served as Kerr County commissioner from 2012 to 2021, told Morning Edition he advocated for a flood warning system with sirens in 2016 after a deadly flood in nearby Wimberley. That system was never built because commissioners were denied funding from state grants and there was public pushback.
Locals were concerned about the more than $1 million price tag. "People did not like the idea of sirens throughout the county," he added.
The central Texas floods killed at least 109 people over the Fourth of July holiday weekend and left more than 160 missing. Many of them are children, most of whom were attending summer camp. Questions have loomed since the floods about what emergency plans were in place.
Texas Gov. Greg Abbott says investigations into storm preparation and response are likely to begin later this week, as state lawmakers prepare for a special session to address the disaster.
Moser says state and local officials are likely to act on implementing more effective warning systems now after the most recent disaster.
"I think it will be more robust, more reliable, more effective. And I don't think it's going to take very long to do," Moser said. "Probably a couple of years at most. At most, a few million dollars, not billions, but a few million dollars to do it. And it can be done."
NPR's Michel Martin spoke with Moser about what the county and state can do to prevent loss of life during future severe weather events.
The following excerpt has been edited for length and clarity.
Michel Martin: Do you think that the county could have done more to warn and protect people?
Tom Moser: Well, let me answer it this way. The county has an emergency management plan which delineates exactly what to do in case of a flood. And it tells who's responsible for what and who's supporting what. So I'm sure that — I don't know this factually — I'm sure they followed that emergency management plan. So I wouldn't have any comment beyond that.
Martin: Earlier this year, the state legislature failed to get a bill out of committee that would have created a statewide funding mechanism for sirens and emergency alerts. And I'm wondering if you think that this tragedy, as terrible as it was, is going to spur them to reconsider that?
Moser: Well, in a positive sense, on this tragic thing, I think it will happen. I think it will be more robust, more reliable, more effective. And I don't think it's going to take very long to do. Probably a couple of years at most. At most, a few million dollars, not billions, but a few million dollars to do it. And it can be done. We're going to do it and use all the current technology that exists and blend those technologies together to give a very, very effective early warning system.
Martin: I want to mention, though, you have extensive experience in product management. You were a project manager for NASA for some like two decades now. Do you think there are other measures that could prevent a similar tragedy in the future, since you had a lot of time to think about it?
Moser: I think there's technology that exists today. There's topographical maps that are digitized that can be used to identify and characterize the terrain. There's ways to predict currently and and with more precision what we think rainfall is going to fall. And then with models, you can determine where the rainfall is going to be and where it's going to go and what the levels are going to be downstream. I think that's the thing that exists today that didn't exist in the past. And believe it or not, use artificial intelligence to bring all that data together and help guide the direction of which alarms should be sent.
Martin: I do have to ask, though, if you feel that had this warning system been built, that lives might have been saved.
Moser: Yes, if the sirens were there, from what I know, just listening to the media and hearing it. I'm not there. I haven't been involved in, you know, the rescue or the day to day things that are going on right now. But yeah, I think if sirens were there, clearly people would have known about it. Would it have saved everybody? No, I don't think so. I think this was an event that's probably one chance in a million of happening.
Martin: So I just wanted to ask what thoughts you have now about what else needs to happen going forward. And it's also a difficult question to ask because people love this area and they love their homes. And there's so many memories that people have attached to these areas. But do you think that people should consider relocating?
Moser: Well, I don't think they should consider relocating. I think they should consider where they're building in proximity to rising water. Develop the system that I just delineated a while ago and — those are tools that can identify flooding in a particular area — make that same tool available all over. But use the same analytical capability to build a system and use it to integrate and use the same information that exists wherever it is throughout the United States. And I think that would benefit everybody. And it's not a huge expense and it can be done very quickly, I'm convinced.
