Internationally renowned architect Frank Gehry is working on a master plan to redevelop the river. The Los Angeles Times said Saturday, Aug. 8, 2015 that Gehry has been working for free since last year on the long-running restoration project. However, many of the details aren't being released, irking one nonprofit group, Friends of the Los Angeles River, which says it can't endorse Gehry and wants a more grass-roots approach to planning.
