Half of Orange County is a humongous floodplain. Building a giant concrete ditch from Corona to the sea seemed like a good idea in the 30s but is really a horrible idea from a ground water reclaimation standpoint. I remember, as a kid, watching the Santa Ana nearly top its banks one February. The problem is not entirely the dam, it's the ability of the entire system to handle the water from a 100 or 200 year flood. It's not a great situation.
This is what I was implying in an earlier post. The original design is too dependant on upstream collection and reclaimation. The lower floodplain itself (save a few stretches in Anaheim, etc) has extremely limited water dispersal/reclaimation ability. Now, with how built up OC is, eminent domaining the massive acreage needed to expand those abilities would be politically impossible.
This whole series of AC memes are exceedingly weak, anon. Just sayin. They are "muh dick" weak, imho.
