It just looks so engineered, which is odd to say given that the original Thomas design was one of the more engineered, manufactured courses in America. The width of the channel is uniform, as is its slope, and the visible rip-rap at the beginning and end of the hole is a visual abomination. It seems like being less OVERTLY concerned with the physical properties of draining the barranca and more with "visuality" could have benefited the project.
I know for a fact that Matt Morton, the superintendent, is committed to displaying a quality product at Riviera, so maybe it's just a matter of letting the work mature for a few more years
