Environmentalists and some elected officials want to restore and preserve open space along local rivers and streambeds. One area slated for a make-over is the Arroyo Seco, a deep channel and occasional stream that carves out a 22-mile path from the San Gabriel mountains, through Pasadena, and to the LA River. Because much of the arroyo hasn't been developed, it's considered to be one of the local streambeds with the most potential for restoration. KPCC's Ilsa Setziol has the story.
