California Berkeley needed to replace the World War II-era student-family housing. Stricter regulations and the need for flood control led to a collaboration with the City of Albany and, to a lesser extent, Berkeley, aimed at giving the creek a more meandering channel, with native plantings, along the south edge of University Village. By 2010, restoration extended from the Union Pacific tracks upstream to the earlier restoration at Eighth Street. There are hopes to extend it to San Pablo Avenue, and to restore a shorter portion just upstream at Kains Street, creating a mini-park next to subsidized housing. If Golden Gate Fields racetrack were to move, some of the large salt marsh could be restored in its place. In April 2019, many fish in the creek were killed by retardant foam used by Berkeley firefighters to prevent a gas-tank explosion. Ecology The creek's steelhead trout population climbed to some 500 individuals by 2006 according to surveys. On December 3, 2012, a Chinook salmon (Oncorhynchus tshawytscha) was videotaped in the creek, the first sighting in recent history.
