The issue is likely due to the creek barrels immediately south of the Greenway tunnel in dire need of sediment/debris removal, causing the overflow to spill over to the Greenway during high water. I notice sediment entering the Greenway tunnel via weepholes at the base of the tunnel. A thorough cleaning of all the barrels would help immensely.
