Upper Penitencia Creek Bypass Channel

Document Description
Upper Penitencia Creek is a tributary that empties into Coyote Creek downstream of U.S. 101. It is a well defined, entrenched channel where it leaves the mountainous area near Dorel Drive. Between Dorel Drive and Piedmont Road, its capacity is approximately 1,000 cubic feet per second (cfs). As the creek continues across the urbanized valley floor towards Coyote Creek, its capacity decreases to approximately 600 cfs near King Road and on downstream. For this reason, major flood events have the potential to result in significant damage to residences and businesses in this portion of the Coyote Watershed. The Reach 1 portion of the project includes the construction of a new concrete bypass channel to accept higher flows from the creek during flood events. The bypass channel would be constructed approximately 200 feet south of the existing bridge crossing on King Road, and empty into Coyote Creek approximately 1,200 feet up stream/south of the existing Upper Penitencia Creek confluence with Coyote Creek. The project location is illustrated in the attached figure. The total bypass channel, and an outlet structure at the Coyote Creek/Upper Penitencia Creek confluence. With implementation of the bypass channel project, the existing creek along Reach 1 would remain the same as it is today.
