Creek goes underground

At this point, the creek flows through a culvert and continues underground for about 100 feet before reemerging. The creek passes under a relatively large, open grassy space near the Dimond Park restrooms. There is a sidewalk placed above the creek's opening, which is bordered by a fence with a sign providing more information about Sausal Creek. This opening is the result of daylighting efforts by the City of Oakland, Friends of Sausal Creek, and Alameda Flood Control. These efforts daylighted, or uncovered, about 250 feet of Sausal Creek, costing about $4M. Measure DD, a bond measure passed in 2002 in Oakland, helped pay for the costs because of the habitat and water quality improvements that Sausal Creek would see as a result of daylighting. The daylighting construction went from 2012 to 2015.
