Lower San Fernando Dam Low-Level Outlet Maintenance (2)
Document Type
NOE - Notice of Exemption
Document Description
The Lower San Fernando Dam is located at the southern end of LADWP’s Van Norman Complex. The dam has a low-level outlet that discharges into what LADWP refers to as San Fernando Creek. The creek receives flow from the Lower San Fernando Detention Basin and discharges into the Bull Creek Extension Channel. The total length of San Fernando Creek is approximately 1,265 feet. The channel width ranges 9-18 feet. The State of California, Department of Water Resources, Division of Safety of Dams (DSOD), regulates dams, including out-of-service reservoirs, to prevent failure, safeguard life, and protect property. DSOD regularly inspects the Lower San Fernando Dam and has requested two actions be taken in their August 31st, 2022 inspection report, including the activity subject to this Notification. Per DSOD, vegetation is obstructing the low-level outlet and, thus, needs to be removed by November 1, 2022. This work is past due and needs to be completed as soon as possible to avoid safety issues. The vegetation obstructing the outlet is dominated by southern cattail and a few arroyo willow trees with potential intruding roots adjacent to the outlet pipe. LADWP proposes to trim the vegetation approximately 25 feet back from the outlet and 25 feet across the width of the creek, temporarily impacting approximately 0.006 acres of southern cattail and 0.004 acres of arroyo willow. The cattail would be cut down to base using hand tools only. Water is present in the creek; however, maintenance activities will avoid the wetted portion of the creek. The cut vegetation would be transported offsite for disposal. Work will take approximately 2-3 days to complete.
