About this file
This document is a set of civil engineering design drawings for the Hot Well Dunes Recreation Area Improvements project for the Bureau of Land Management's Safford Field Office in Arizona. The drawings detail road grading and site improvements, specifically focusing on a 1.65-mile site road (stations 60+00 to 86+37) and a fee station/wildlife pond area.
Key design elements include road grading with 25-foot wide road sections, two typical road section designs (crowned and cross-slope), stabilization with 6-inch rolled aggregate base, and site improvements such as a new fee collection station, vault toilet, shade structure with picnic table, accessible grill, parking areas, concrete sidewalks, water line installation, and various site furnishings like signs, trash cans, and rail fencing. The drawings are part of Additive #1, which encompasses furnishing labor, materials, equipment, and resources to overexcavate, grade, and stabilize the site road and major turnouts. The project is designed by GLHN Architects & Engineers and dated October 28, 2024, with civil site plans and road section details provided across multiple sheets.
