It was somewhere close to a 1 in 50 year type flood.
There is an obelisk by Broadway and Canyon with marks on it representing different levels for different types of floods. The waters didn't quite make the 50 year mark.
One in forty nine years sounds a heck of a lot less sexy.
That's why you need an interpreter to tell you that a one in one thousand year rain fall as reported in Climate Central, doesn't translate into a one in one thousand year flood as reported by Time Magazine's "ecocentric" blog
In our rush to judge any eco news to be "biblical" in media terms we often get things wrong. That's why I take things with a generous portion of salt. I ask myself what is their agenda. Anyone can write a blog. I consider Journalists to be no more informed than the general public. Their only qualification is that they can write better, no one guarantees they are more informed.
I believe, in my uninformed scientific opinion, that climate change is the greatest environmental issue facing our species today. To win the support of the general public in our efforts to curb greenhouse gasses we need to be extra cautious not to misinform. Climate change and floods are bad enough all by themselves, they don't need help.
