A week after catastrophic floods in Central Texas, key questions remain unanswered about how state and local officials prepared for and responded to the disaster.

Businesses large and small also sprang into action to help the community. Grocery chain H-E-B, which started in Kerrville, one of the cities affected by the floods, has been donating food and supplies through the Red Cross. San Antonio-based fast-food chain Whataburger said it would provide meals to first responders.
