Was this true 'state of the art' back when the flood control wall was built? Or is that more current knowledge? (I have no idea)."Prochaska said a rule of thumb is that the length of sheet piling below a canal bottom should be two to three times longer than the length extending above the canal bottom"
If this was state of the art back then, it will fuel theories of conspiracy in corruption along these lines: all those folks who signed off on the plans had to be involved. The driving motivation would be someone (contractor probably) who wanted to save a little money (make a little money) by shorting on materials.
Not saying I buy this theory - but thats what I expect to happen.
