2 miles of Steep
Terrain,
East of Jacumba?
.
Or west of Tecate?
.
I’d choose Campo.
The recent award I was talking about is going to extend the new San Diego barriers East, from where they currently end (Otay Mesa, just past where the prototypes were built). There is some real steep slope, that is going to really challenge installation, and road building. No previous barrier has been there.
One of the barriers will be extended two miles (Id guess the primary barrier) and the other will be extended one and a half miles. Then it will meet up with good pre-existing runs of bollards, on the other side of this gap, to form a continuous barrier.
Although it is not a lot of miles, San Diego has always been a very high value target, with high traffic. It could be subject to mob rush tactics by a future caravan, if that gap is left open. Bollards proved very effective against last years caravan, and against the old crowd rush techniques that used to be common in San Diego. Total showstoppers.
String a few rolls of concertina on top of the bollards, and a few guys with a lot of CS (tear gas) can hold off hundreds.
Jacumba Wilderness has a pretty long run getting put in now, but I think it is mostly the flat area.
The Military Construction contracts that are just starting to get awarded, are supposed to include three miles of secondary barrier around the Tecate Port of Entry (30 footers), and about 13 miles of (30 foot) secondary barrier around Calexico POE (mostly to West side).
