4. Drawings - 23N60.pdf

The file contains detailed engineering drawings for a Weld Wire Wall construction project (Road 23N60 - 3.2) located in the Plumas National Forest, Feather River Ranger District in California. The project involves constructing an approximately 85-foot mechanically stabilized earth (MSE) wall along Road 23N60, with specific technical specifications for wall construction, drainage systems, and site preparation.

Key technical details include a multi-tiered wall design using compacted structure fill, non-woven geo-textile fabrics, geo-membranes, and drainage components. The project schedule indicates a 5/8/2024 design date, with construction requiring road closures between Butte County Road 27562 and Marble Creek Bridge. The wall will include multiple construction tiers, specific backfill requirements, and detailed drainage system specifications using 6" HDPE perforated drain pipes and rock fill. The project is part of the USDA Forest Service's Pacific Southwest region and involves precise engineering specifications for road infrastructure improvement.
