About this file

Written by GovTribe AI · Sep 19, 2025

This is a set of preliminary design documents for a road rehabilitation project on Forest Road 221 in the Nez Perce-Clearwater National Forest, Idaho County, Idaho. The project involves 29.70 miles of roadway improvements, including pavement preservation, subexcavation, pavement repair, and drainage work. The rehabilitation techniques include chip seal, full depth reclamation with cement (in 8-inch and 12-inch depths), deep patching, crack sealing, and reinforced soil slope installation. The project will employ various construction methods such as roadway aggregate placement, geotextile stabilization, and underdrain system installation. Additional features include culvert replacements, temporary traffic control, and environmental mitigation measures like streambed material placement. The work is being prepared by the Federal Highway Administration's Western Federal Lands Highway Division, with a project manager named W. Schmidt, and is currently in the preliminary design phase, not yet ready for construction.

When directed, camber pipe culverts upward from a chord through the inlet and outlet inverts an ordinate amount equal to 1% of the pipe length. Develop camber on a parabolic curve. If the midpoint elevation on the parabolic curve as designed exceeds the elevation of the inlet invert, reduce the amount of camber or increase the pipe culvert gradient.

H equals the diameter of all round pipe culverts or the rise dimension of all pipe arch culverts.

See Section 704 for bedding and backfill requirements.
