Build a pipeline from Canada & the Northern States to California - and when it snows - shovel all that white stuff into the pipe - instead of piling it in the streets.
The green weenies would let it flow into the ocean to protect whatever lives in the pipeline.
Screw the citizens.
Actually some of the Indian tribes in the Dakotas have water rights (and available water) that far exceeds their needs. A pipeline to CO or NM in the future is not out of the question.
I had a similar thought years ago, about putting a massive drainage system in frequently flooded areas like the Mississippi River basin and moving the water to places where it is needed, using wind and solar to power the pumping stations where they are necessary. Sounds like a win-win to me, reduce flood damage and increase productive acreage, but folks pooh-poohed the idea as too costly. Like all that rebuilding every few years and the loss of usable land isn't costly?
