Border wall construction plans continue underway in Hidalgo and Starr counties.

Last week, the Rio Grande city commission gave the green light for Customs and Border Patrol Officials to survey the land for the border wall.

But experts, like Hector Barrera, Rio Grande City public works director, say not all areas in the city are well-equipped for such an infrastructure.

“Our overflow drains and it will create problems for the city,” he said.

The concern is the flood risk a border wall could pose.

That’s because unlike in Hidalgo county, experts say Starr County doesn’t have levee walls to support the proposed border construction without creating future concerns.

Government border wall project maps first released by The Monitor and Texas Observer indicate the border wall could cut across floodplains in Rio Grande City.

“There’s probability of the water staying back and overflowing our city, city streets, subdivisions,” said Barrera of the possible location of the proposed construction.

Deputy city manager Elisa Beas says that a wall could halt water flow in a city already limited in its drainage system.

“Here in Starr County, it’s hilly,” she said. “The city is in the middle and the water has to go through the city, basically.”

Rio Grande City’s drainage infrastructure is limited to a few overflow ditches and lacks an underground sewer system. Beas says the area only has a few small underground sewers along Expressway 83 which were installed by the Texas Department of Transportation.

Deputy city manager said the drainage concerns have been ongoing for years.

Construction of the border wall could happen as soon as February.
