Attachment 4-RIVERROAD_MAP.pdf

This document is a project map for the Salmon River Road maintenance project located in North Fork, Idaho, approximately 17 miles from the project start point. The map illustrates a road treatment application project involving the use of magnesium chloride (MgCl2) as a dust suppressant and road stabilizer.

The project specifies application of MgCl2 at a rate of 0.30 gallons per square yard across a 16-foot-wide road section at the project's beginning. The scope transitions to a 12-foot width at designated points, with the application rate remaining constant at 0.30 gallons per square yard. The project encompasses multiple segments marked by named locations including Spring Creek, Ebenezer Bar, Cache Bar, and Colson Creek, with distinct start and end points clearly delineated on the topographic map. The treatment application area extends along the Salmon River Road corridor, with width transitions noted and marked locations for project commencement and conclusion. Key reference points include Lookout areas and various creeks that serve as geographic markers for the project boundaries and application zones.
