Nim Kidd, chief of the Texas Division of Emergency Management and representatives from the Upper Guadalupe River Authority are expected to testify.

"You seem uninterested in learning what went wrong and how to respond better. Do the victims and survivors in Texas deserve an apology?"

AUSTIN, Texas (AP) — A review by Texas lawmakers into the catastrophic July 4 floods has no intention of second-guessing decisions by local officials or assigning blame over the tragedy that killed at least 136 people, a top Republican leading the effort said Wednesday.

Response to the Hill Country floods is the top priority for a special session of the Texas Legislature. Lawmakers have already filed more than a dozen bills.

The flash floods that killed at least 135 people in Texas' Hill Country was the main topic during the opening of a special legislative session in the state on Monday.

FEMA’s maps are essential tools for identifying flood risks, but they have significant gaps that limit their effectiveness.

Just three people remain missing — down from nearly 100 at last count — since the Texas Hill Country was pounded by massive flooding on July 4, officials said Saturday.
