| Location Description | Kittyhawk Road, Airway Blvd, North I-580, Arroyo las Positas, Cayetano Creek |
This project will remove sediment accumulated at culverts in Kittyhawk Road and along Airway Blvd. Construct a 2.8 acre sediment basin north of I-580 and downstream of confluence of Arroyo las Positas with Cayetano Creek with associated mitigation measures for sediment removal. Construct levees. Plant shaded riverine aquatic cover along 4,000 feet of channel banks.
The capacity deficiency of Arroyo las Positas is exacerbated by the aggradation of the channel due to excessive sediment desposition upstream of the Las Positas Golf Course. The project purpose is to increase the reach capacity and curtail future aggradation by trapping sediment loads in a sediment basin located upstream of I-580.
