“What is the true story about the section of the border wall at the Rio Grande ? I have heard that the ground underneath the wall is eroding.”
Part of it is. The basic design was to gently grade/slope the riverbank and stabilize the soil with grass to prevent erosion. The intent was to make the whole stretch (over 3 miles) suitable for rapid deployment of Border Patrol Maritime Units - they could just run their river boats straight up onto the banks and jump out.
Along one stretch of the bank though, the seed did not take, and the freshly worked soil was susceptible to erosion - when Hurricane Hanna dropped 16 inches of rain, mostly over one night.
What Tommy Fisher said about this in court, was that this kind of thing is normal in construction projects, and that he would patch up spots as needed until the grass took hold, and the soil packed down. In some spots, that just might not work (perhaps unfavorable soil). If that is the case in some spots, he would put rip rap (a heap of big rocks/boulders) as is commonly done at the base of bridges.
Thanks for the reply. I have heard a lot of stories about this. Very few favorable to Fisher .
Surprise , surprise.
