FEMA and the U.S. Small Business Administration, in coordination with the Texas Division of Emergency Management, are opening a Disaster Recovery Center in Kerrville on Thursday, July 10, to help homeowners, renters and business owners impacted by the flooding.

New human settlements constructed in recent years have made the waterway more hazardous, UT-Arlington civil engineering professor says.

Also: San Antonio mourned the victims in a Travis Park vigil; UTSA said one of its teachers died in the Guadalupe River flood; Kerrville officials said a privately owned drone collided with a helicopter conducting search and rescue operations.

Of all the counties affected, Kerr County suffered the greatest losses as a deadly wall of water roared down the Guadalupe River in the early morning hours of July 4. Wednesday evening, the City of Kerrville came together in a vigil at Antler Stadium to pray for the victims and those still missing after the flood.

Despite officials urging civilians to stay away, volunteers have joined the search for missing people and the cleanup on the Guadalupe River.

Officials have reported that 27 campers and counselors from Camp Mystic died in the devastating floods, with five campers and a counselor still missing.

Before hundreds of first responders and volunteers from around the country came to help, it was the local residents of Texas Hill Country who faced down a deadly wall of water along the Gaudalope River and witnessed terrifying scenes.

During an interview with Fox News Monday afternoon, Lt. Gov. Dan Patrick said that he and Gov. Greg Abbott agreed that the state should erect sirens along the Guadalupe River.

The recent disaster has some thinking back to a similar tragedy almost 40 years ago that occurred in the same month and nearly the same place.

Hill Country residents and volunteers on Tuesday continued picking up the pieces that the deadly waterway left behind days earlier.
