We built new infrastructure along the border east and west of the San Luis Arizona Port of Entry in 2006. The existing fence was quickly lengthened, and we added second and third layers to that fencing in urban areas. Lighting, roads and increased surveillance were added to aid agents patrolling the border.
Although there is still work to do, the border in Yuma sector today is more secure because of this investment. Even under lax enforcement standards, apprehensions in fiscal year 2016 were roughly a 10th of what they were in FY 2005 — and are on track to be even lower this year. Crime has significantly decreased in the Yuma area, and smugglers now look for other less difficult areas of the border to cross — often areas without fencing.
