The LAist just published a piece about what the Los Angeles River might look like in 20 years, and the story was also on KPCC, if you'd rather listen than read. The author is KPCC's Susanne Whatley. And this beautiful picture (also on LAist) is by Steve Lyon and was on Flickr Creative Commons.
AND, there's a 7-minute video of a drone flyover of the Taylor Yard (used to be Union Pacific property), which is along the east river bank where the river travels between the Silver Lake & Mt. Washington neighborhoods. Huge area, needs clean up, but it could be developed as a riverside park.
Thanks, Flo Selfman, (@floselfman) for tweeting this out to your followers!
