About this file
This document is a standard trail plan technical drawing for clearing limits and brushing, issued by the U.S. Department of Agriculture Forest Service for the 2025 FNF Trail Contract. The drawing provides detailed specifications for trail clearing and maintenance, specifically for Trail Class 3 Pack and Saddle trails. Key technical details include standardized clearing and mowing limits, with uphill and downhill widths of 4 feet, and specific disposal methods such as "lop and scatter outside trailway" (D1) or "lop and scatter on fill slope" (D2). For trails on slopes greater than 35%, the clearing width adjustments are explicitly noted, with column J set to 6 feet and column K to 2 feet. The document includes matrices for clearing methods, disposal types, and accompanying comments, providing a comprehensive technical guide for trail maintenance and brush management.
