During peak of the storm, 26 inches of rain fell during one 24-hour period, and 34 inches was recorded in that week. The impact on Houston's Transportation System was severe; all major highways were closed and total damages amounted to $5 million. There was $1 million in roadway damage alone. Additionally, the flooding caused $3 million in damages to ITS and communication facilities. By June 9th, operational rates for Closed Circuit Television (CCTV) and dynamic message signs (DMS) had been reduced by 55.6 percent and 23.8 percent respectively.
Considering the scale of the flooding, Houston TranStar reacted well, continuing to function while several other government agencies and private organizations became non-operational.
