And all this will be paid by Mexico, of course. Here is John Oliver’s analysis during the campaign on what a thirty-five foot wall will cost. (Summary, $25-billion, about double what Trump was estimating at the time, and about $2-billion a year thereafter for maintenance. That works out to $77 per person in the country just to build it.)
He also touches on just how likely Mexico is to foot the bill, whatever it is.
Does anyone have any good engineering details on how the Tijuana River crosses the border, under the existing wall?
(I live in San Diego, and I’ve driven along the border on both sides in that area…and have no idea how the river gets across. Google maps photo view appears to show the big concrete river channel just going openly across.)
This is the big question I’ve not heard wall debates cover: rivers! Gulches, creeks, canyons, arroyos! You can’t block the water, or you’ll have, not a wall, but a dam. But if water can get through…why can’t people? If you put in a grating, it’ll just get plugged with debris.
(Also, really steep hillsides. Will the wall be reduced to a more nominal fence in regions where the terrain pretty much negates the possibility of crossing anyway?)
Engineering nightmare, and hundred-billion dollar boondoggle…and most illegal immigrants arrive via ordinary transportation anyway! Only a relative few cross the desert; most come in a car, bus, boat, or plane. A great, great many arrive legally, and then outstay their permit. No wall is going to do jack boogers against that.
Of course moose is not the only way of effectively dealing with illegal immigration from Mexico and Central America. syncrolecyne already covered that very nicely at post 38. Quite simply, if you stabilize the region, you’ll cut the flood of people wanting into the USA down to a trickle. Read up on Programa Frontera Sur. Most of the people trying to get into the USA from Mexico are not Mexicans. They are only transiting Mexico on their way to the USA, and Mexico is diligently trying to keep them from getting into Mexico in the first place.
The more you shit on Mexico, the less inclined Mexico will be to act as your first line of defence against illegal immigration from Central America. The less you do to stabilize Central America, the greater your illegal immigration problem will become.
Now getting back to moose, remember that the Mexican/USA border cuts through almost countless communities – ecological communities. Now I’m not suggesting that you populate your southern border with moose, but rather I am pointing out that your southern border is already populated by a great many species of plant and animal life. If you build an impenetrable wall, you will permanently bisect habitats. That’s not a wise thing to do. That is a monumentally stupid, even Trumpidian thing to do.
While that’s true, it’s (alas) not at all uncommon. Big freeways cut through habitats, separating them, and big cities are worse, as they consume and destroy habitats entirely.
Now, how they are going to let water drain through watercourses crossed by the wall, I cannot guess. Seems like a really tricky engineering issue.
Just put in cellphone coverage, then you can find anyone who’s out there illegally. We have long since passed the point when any human being is capable of switching their phone off for long enough to walk across a desert.
