HOUSTON – It didn’t take much rain to flood a low-lying underpass along Navigation Boulevard again this week, cutting off a key route in east Houston and renewing concerns about drainage infrastructure and maintenance.
By Tuesday, water levels at the underpass had reached about six feet, forcing drivers to turn around and find alternate routes.
The flooding has become a recurring disruption in the area after even modest rainfall.
“It’s very aggravating,” one nearby worker said.
The high water also complicates travel beyond the underpass. Drivers attempting detours often encounter additional delays due to nearby train crossings.
“It’s 2026. The sewer and drainage systems should be up to date, especially with the growth we’ve had in this area,” said Lisa Purdum, who works nearby.
Local businesses say the flooding creates scheduling challenges. Dr. Natalie Carrizales, a dentist in the area, said patient appointments have had to be adjusted.
“We’ve had to extend grace periods. Usually, our grace period is 15 minutes. We’ve had to increase that to 20 or 25 minutes because patients get caught either behind the train or at the underpass,” Carrizales said.
City officials say the problem is not solely tied to rainfall. A drainage pipe was damaged during construction, and portions of the system are currently blocked. Officials also say the pipe that drains into Buffalo Bayou can become submerged during heavy rain, causing water to back up into the underpass.
The city recommends residents report flooding issues through 311 and keep their service request numbers for follow-up. Officials also encourage residents to document problems with photos or video and submit them to City Council offices or speak during council meetings.
A contractor is expected to be on-site Thursday to begin inspections and plan repairs.
Officials also remind drivers to avoid flooded roadways and follow safety guidance: turn around, don’t drown.
