The guy that puy the wall up owned a landscape com. and rented that machine and told the owner of the lot that he had done many walls, the wall was engineered but the guy can't read plans, the wall called for 1 to 6 tip back but the guy went straight up 28' feet and did not back fill as he went up but went he got to the top and because there was no tip back it took way to much back fill put in and the wheigh of the backfill compacing it started to push the bottom of the out so they were stacking blocks end to end in from to try and stop the wall from moving, the guy's wife had showed up with lunch when the wall came over on the machine,It took a 225 ton crawer crane to get the 320 out!!
