Minor Alteration No. WA2026036 – Irrigation Pipe Replacement Project

Minor Alteration No. WA2026036 for the Irrigation Pipe Replacement Project is a forecast action by the Central Valley Flood Protection Board in California. The project focuses on the authorization and maintenance of an existing irrigation pipe system located at levee mile 2.72 on Unit No. 01 of the Sacramento River right bank levee in West Sacramento, Yolo County. Originally constructed in 1965 and documented in the Operation and Maintenance Manual As Builts file 50-04-3756, the infrastructure consists of a 14-inch diameter irrigation pipe, a slant pump on a support structure, a 12-inch intake pipe within a 20-inch steel sleeve, and a 2-inch electrical conduit. Additional components include a corrugated metal pipe enclosure with a positive closure device on the waterside levee shoulder and a siphon breaker on the landside levee shoulder. The project is categorized under NAICS code 237990 and is managed by the Central Valley Flood Protection Board. Under Permit No. 20091, the project has been granted a Notice of Exemption from the California Environmental Quality Act under the Class 1 categorical exemption for existing facilities, as the work involves minor alterations and maintenance with no expansion of use and negligible environmental impact. The scope of work is specifically aligned with the technical specifications found on sheets 6.3, 15.6, and 17.2 for Station 104+12 of the original 1965 bank protection records.
