It sounds like you’re in the know—could you describe phases two and three for us?
“could you describe phases two and three for us?”
They can always (and likely have) change the plan (like Trump recently said they would defer segments in California, until the whole wall is funded), the original plan that was leaked last year was:
Phase One. The first phase would be the smallest, targeting sections covering 26 miles (42 km) near San Diego, Calif.; El Paso, Texas; and in Texas’s Rio Grande Valley.
Phase Two. 151 miles (242 km) of border in and around the Rio Grande Valley; Laredo, Texas; Tucson, Ariz.; El Paso, Texas and Big Bend, Texas.
Phase Three. Up to an unspecified 1,080 miles (1,728 km), essentially sealing off the entire U.S.-Mexico border.
It is basically doing the high traffic urbanized areas first, and then extending into the more rural stretches later. They have been taking their priorities from the customer (DHS/CBP), based on their experience (arrests, seizures, assaults on officers).
