Absolutely, KC. The project looks as simple as pouring a concrete driveway, but it’s much more complex. Drainage. Enormous changing pressures depending on use and quantity of water. Temperature extremes. A driveway can crack and it poses no real issues. I can lose its flatness - a corner can lift or drop and the result is really insignificant. I can drive up a bumpy driveway as easily as I can drive up a gravel road.
I think that the original spillway was well designed and built, but time takes its toll. There’s going to be a lot of discovery behind what all failed when things settle down. They will incorporate the original terrain into the design. There’s so much involved.
Has anyone else noticed that there doesn’t seem to be any rebar in the spillway construction?
