Title

Rehabilitation of Storm Drain Outfall at Remington Court Project (UY-17-01)

Description

Initial Study, Draft Mitigated Negative Declaration, NOI and NOC - The City of Sunnyvale Public Works Department (City) is proposing to repair a failing storm drain outfall pipe that discharges to Stevens Creek at the end of West Remington Drive, in Sunnyvale, California. The City has determined that a 60-inch storm drain outfall that discharges directly into Stevens Creek has deteriorated and a small portion at the end of the pipe has fallen into the outfall channel connected to the creek. Engineering reports concluded that the deterioration of pipe and the lack of proper erosion control measures at the discharge point and further downstream of the low-flow channel were the key reasons for the failure of the storm drain outfall pipe and the deepening of the outfall channel. The City is proposing a project to replace the failed segment of pipeline and alter the drainage outlet to prevent future erosion at the discharge point and to prevent backups from the creek into the municipal storm drainage system.
