The Department of Homeland Security has requested assistance from the Defense Department to mount approximately 218 miles of new and replacement barriers along the US-Mexico border, according to documents released by the Sierra Club, a grassroots environmental organization.
In a February 25 memo to the Defense Department, the Department of Homeland Security identifies four sectors along the southern border that require reinforcement through barriers, light installation and other measures.
