This is Laguna Creek at Sun Valley Dr, really. Didn't see an actual looking creek but it's down there somewhere.
As far as I'm concerned the creek hasn't been a natural water way for ever. Probably since they built Laguna Canyon Rd. Maybe north of El Toro or further north past the toll road it's kinda natural. But once it's south of El Toro Rd it's just a man made ditch for directing water past developed properties and out to the ocean at Main Beach.
The title refers to an article in the Coastline Pilot at the grant to clean up part of the creek. I wonder if what I photograph at Sun Valley Dr will get cleaned out.
