These are technical trail maintenance design plans for the Gaoa Deferred Trail Maintenance project in the Nez Perce-Clearwater National Forest, prepared by the U.S. Department of Agriculture Forest Service. The seven-page document includes detailed engineering diagrams for trail maintenance activities, specifically covering standard trail terms, clearing limits for trees and logs, brushing techniques, waterbar construction, drain dip sections, and check dam installations.

The technical plans provide comprehensive specifications for trail maintenance, including precise measurements and methods for clearing trail corridors, removing vegetation and obstacles, managing drainage, and stabilizing trail surfaces. Key technical specifications include clearing width standards (ranging from 24"-48"), brushing limits, logging out procedures, waterbar construction using logs or treated timber, drain dip configurations with rock spillways, and various check dam design types using materials like rocks, logs, sawn timber, and railroad ties. Each diagram includes detailed notes on installation techniques, material selection, slope management, and environmental considerations specific to different trail grades and terrain conditions.
