These engineering drawings detail road improvement plans for the Hot Well Dunes Recreation Area site road, located in the Safford Field Office, Arizona. The project involves grading and stabilizing a 25-foot wide, 1.65-mile existing road with multiple sections spanning stations 30+00 to 60+00, including road sections with varying elevation changes and road profiles. The drawings, prepared by GLHN Architects & Engineers for the Bureau of Land Management, show detailed road cross-sections, proposed grading, existing terrain, and specific site improvements.

Key technical details include installing a new 2" water line, new site markers, speed limit signage, and constructing campsites (#10-14) along the road route. The project includes an Additive #1 scope that consists of overexcavating, grading, and stabilizing the site road with 6" rolled aggregate base, excluding the water line installation. The road improvements involve precise elevation adjustments, road widening, and infrastructure enhancements to support recreational access in the Hot Well Dunes area.
