WASHINGTON (AP) — A federal judge is allowing the Department of Homeland Security to go ahead for now with plans to build a border wall through a levee system protecting a small Texas town on the border with Mexico, rejecting arguments by the town that the wall could lead to flooding. The town's development district sued earlier this year to stop the department from going forward with construction.

In court documents, Presidio's development district said Customs and Border Protection plans to "replace the earthen slope of the existing levee with a concrete wall, with 30-foot steel bollard panels installed on top."
