About this file

This document is a standard trail plan from the U.S. Department of Agriculture Forest Service detailing clearing and brushing specifications for the 2025 FNF Trail Contract. The plan provides detailed technical guidelines for trail maintenance, specifically for a Trail Class 3 Pack and Saddle trail, with precise measurements for brushing and clearing limits.

The document specifies clearing widths of 4 feet uphill and downhill, with special instructions for slopes over 35% (requiring 6 feet and 2 feet of clearing respectively). Disposal methods are comprehensively outlined, including options such as "lop and scatter outside trailway", "lop and scatter on fill slope", "pile and burn", "chip", and "haul to disposal site". The drawing (STD 912-02) provides a visual schematic of clearing zones, brushing limits, and mowing limits, with a note referring to additional clear zone limit details on another standard sheet (STD_912-01).
