South Tahoe Public Utility District Tallac Creek Pipeline Emergency Repair Project
Document Type
NOE - Notice of Exemption
Document Description
The South Tahoe Public Utility District (STPUD) sewer pipeline intersects Tallac Creek just south of Baldwin Beach on Lake Tahoe. This pipeline's structural integrity at the crossing of Tallac Creek has been compromised due to erosion from Tallac Creek around the foundation of the concrete encasement surrounding the pipeline. STPUD proposes to temporarily stabilize the concrete encasement using steel beams spanning above the Tallac Creek channel. The steel beams would be attached to support beams placed on pre-cast concrete foundations situated outside the low-flow creek bed on the banks of Tallac Creek. The concrete encasement would be supported with a series of thick ratchet straps wrapped on the underside of the encasement and secured to the steel beams by tensioning the ratchet straps. The design concept could be constructed without placing equipment in Tallac Creek and would facilitate installation of permanent stabilization measures as part of the future permanent grade control structure project proposed for implementation in September 2022.
