Minor Alteration No. WA2025084 – Syphon Irrigation Pipe in the Georgiana Slough Project

Minor Alteration No. WA2025084 is a project managed by the Central Valley Flood Protection Board to repair a siphon irrigation pipe and pump assembly located on the right bank of the Georgiana Slough in Reclamation District 556, Sacramento County. The scope of work involves lowering the pump platform, excavating to expose the existing 10-inch pipe, and installing a 10-inch by 8-inch reducer. Additionally, the project requires the installation of an 8-inch pipe connecting the reducer to the pump and the placement of a new positive closure device on the waterside pump connection. The project is governed by Board Permit No. 11177 and is exempt from CEQA under Class 1 and Class 4 categorical exemptions, as it constitutes a minor alteration without significant environmental impact. A critical requirement of the contract is the restoration of the levee to pre-project conditions in strict accordance with Title 23 standards. The project is administered by the Central Valley Flood Protection Board, with Jordan Robbins serving as the primary point of contact and Chris Lief as the Executive Officer.
