About this file
This document is a set of technical drawings and site plans for Forest Road Improvements on Colby Canyon Road in the Angeles National Forest, Pacific Southwest Region, dated 8/4/2025. The project involves road upgrades for the Rowher OHV (Off-Highway Vehicle) area, specifically focusing on installing block mats perpendicular to traffic flow and establishing rolling dips. The technical specifications include:
Key technical details include three satellite/aerial map views showing proposed road work locations, with black rectangular blocks indicating block mat placement. A detailed cross-section diagram (U.S.D.A. Forest Service R-5 standard) provides specifications for a waterbar installation, with notes specifying that the water bar shall be compacted per specification, maintain a 4% outslope, catch drainage from the roadway, and have associated ditches constructed where specified. The typical cross-section shows a road grade between 15° to 25° with specific geometric requirements for inside road edges and overall road surface configuration.
