California Department of Water Resources
Banks Pumping Plant (BAPP) Culvert Clearing (OM-DFD-2021-021)
NOE - Notice of Exemption
Delta Field Division (DFD) staff will perform maintenance along the BAPP intake channel. DFD staff will remove sediment from the culverts adjacent to the lower intake roadways along both the primary and secondary side of the channel. The accumulation of dirt in the culverts obstructs storm water flow and must be removed so that the culverts will be returned to original specifications. The intake roads are about two miles long and extend east from the BAPP to Byron Highway. The upstream opening of the culvert will be cleared by hand tools or a backhoe if necessary, pushing the material into the v-ditch. Culverts will be cleaned using a truck staged on either the primary or secondary road with a fire hose connected to a three-inch water pump. The hose and pump will inject high pressure raw water through the culvert until it is clear of sediment and obstructions. Water will be injected from the upstream towards the downstream direction so that the discharge of water will mimic natural stormwater runoff. Access to the site is directly off Kelso Road and Byron Highway. Staging of equipment will be on established paved and unpaved roads. All work will be within DWR right-of-way.
