About this file
This is a U.S. Department of Agriculture Forest Service Standard Trail Plan technical drawing for the 2025 PNT Trail Contract, specifically focusing on clearing limits for trees and logs. The document details precise specifications for trail clearing, including clearing methods, tree removal, and disposal techniques for Trail Class 3 Pack and Saddle trails. Key specifications include clearing widths of 4 ft. downhill and 10 ft. total, with specific guidelines for leave trees, hazard tree removal, and maximum obstruction heights. The clearing method is designated as C1 (Trail Class 3 Pack and Saddle) for Trails #26, #3, and #7, with disposal methods ranging from lop and scatter to chipping and hauling to disposal sites. The technical drawing provides comprehensive visual and tabular guidance for trail maintenance and clearing operations, including details on clear zone widths, stump heights, and tree removal parameters, particularly for trails on slopes greater than 35%.
