Representatives from the U.S. Army Corps of Engineers have started meeting with Big Bend area landowners about the prospect of border walls on their land. Landowners say they're concerned about flood risks and the destruction of archeological sites.

Advocates are rushing to help landowners with legal aid in sparsely populated rural areas along the Rio Grande in the path of the border wall. The federal government's efforts to contact landowners about the project has hit a snag due to complicated land ownership.
