About this file
This document is a Pit Development Plan for the Champion Creek Pit Rock Crushing Project located in the Sawtooth National Forest, Sawtooth National Recreation Area, Custer County, Idaho, prepared by the United States Department of Agriculture Forest Service, Intermountain Region (R04). The plan was drawn and approved on June 30, 2026, with recommendations from Staff Engineer Braidy K. Richins, PE, and Forest Engineer Shawn Robnett, PE.
The development plan establishes operational parameters for rock crushing activities at the Champion Creek Pit site. Key requirements include: all materials and workmanship must comply with federal highway construction standards; all materials and work are subject to inspection and approval by the United States Forest Service Contracting Officer, CO Representative, or other approved personnel; construction equipment must be pressure washed before entering National Forest System lands to prevent transport of noxious weeds, with coordination by the Contracting Officer; contractor damage to the project site must be minimized; existing material stockpiles outside the pit development area must be relocated prior to construction; pit development boundary expansion is limited and flagged on-the-ground by the Contracting Officer; aggregate stockpile areas are flagged on-the-ground prior to work commencement with minimum size specifications; and pit drainage must be sloped to drain water away from the aggregate stockpile and from higher to lower terrain. The plan includes a vicinity map with travel directions from the Sawtooth NRA Ranger Station Office, approximately 13.5 miles south on State Highway 75, then left onto Forest Road #458 for approximately 0.2 miles to the pit location.
