About this file
These are project drawings for the GAOA Scenic Byway Road Repairs project in the Sierra National Forest, Madera County, California. The seven-sheet technical document includes detailed engineering specifications for road infrastructure improvements, specifically covering:
- Typical cross-section designs for road grading with variations including crowned, outslope, and inslope configurations, showing road shoulder widths, fill slopes, and drainage specifications. The drawings include technical details for roadway geometry, including 2:1 fill slopes, 1.5:1 backslopes, and 2% grade specifications. Additional sheets provide comprehensive details for overside drain installations, culvert installations, riprap placement, and roadway vegetation clearing procedures. The project focuses on National Forest System Road (NFSR) 6S10X, with work including 3" layer base rock replacement, culvert replacements, and roadside vegetation management. The project is located near Oakhurst, CA, with precise GPS coordinates provided, and the drawings are dated 2/27/2025, suggesting an upcoming infrastructure rehabilitation project for the scenic byway.
