Williamson County officials urged people located near the Shady River, Good Water and San Gabriel RV parks in Georgetown to evacuate Tuesday morning due to rising floodwaters.

“We have two boat crews that are standing by ready to respond in the event that we need them,” Bruce Clements, director of emergency management for Williamson County, said at a news conference Tuesday afternoon. “Once we get to that point where we see that the waters — the floodwaters — have receded and we no longer have the potential to field resources, then we will stand down our emergency operations center.”

A flash flood warning in effect for parts of Williamson County was expected to end at 6:15 p.m. Tuesday, emergency officials said.

Officials said, in total, 20 families were evacuated. A temporary evacuation site was opened at the Georgetown Church of the Nazarene on East University Avenue.

The warned area included much of Williamson County, including Round Rock, Georgetown, Leander, Hutto, Liberty Hill, Jarrell and Florence. The affected areas could see “life threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses,” the National Weather Service said on Tuesday.

Two to four inches of rain fell in the area Tuesday morning, and additional rainfall continued throughout the day. A flash flood warning is issued when sudden, violent floodwaters are imminent or already happening, the NWS said. People in flood-prone areas should move to higher ground immediately.

People driving in Williamson County are encouraged to “turn around, don’t drown” when encountering flooded roads. Most flood deaths occur in vehicles, the NWS said.

In hilly areas, there are hundreds of low water crossings which are potentially dangerous in heavy rain.

RV park residents evacuate

Elizabeth Tamez and her husband have lived at the Shady River RV park for five years. She expected Tuesday to be like any other rainy day.

“But then the rain didn’t stop for hours and hours,” Tamez said.

Tamez was in the process of gathering and preparing her belongings for evacuation on Tuesday afternoon. She carefully stacked planters of flowers on top of each other underneath a pop-up canopy tent, hoping to use them as a sort of protective barrier for other belongings.

“I love my plants. I love them,” she said. “So unfortunately, I’m using them just to protect my other value items … So we’ll see. Maybe it’s not going to be major this time, but you never know. It’s better to be safe than sorry.”

Tamez said she and her husband were out of town when the RV park flooded during last July’s deadly storms. They lost many of their belongings, including three vehicles. But like many residents, they decided to return to the park after it was cleaned up.

“This is a beautiful place to live. It’s beautiful. It’s [a] gorgeous neighborhood. We feel safe, love[d]. I mean, we are a community,” Tamez said. “It’s not another place that you live, we are family here. That’s why we love this.”

Shauna Thayer and her teenage daughter rushed to the Shady River RV Park after hearing about the evacuation. The pair live a couple miles down the road, and they were involved in the park’s cleanup and recovery after last summer’s storms.

Thayer said Tuesday’s evacuation was “so much more efficient” compared to last July.

“I think this time, everyone knew to take it seriously,” she said. “Law enforcement and county services showed up incredibly quickly and have been really efficient. The police have a drone in the air monitoring the river levels.”

Thayer said most residents voluntarily chose to evacuate, and “an incredible number of strangers” showed up to help people get to safety.
