Written by GovTribe AI · Jun 12, 2026

This is a construction design and planning document for the Wickersham Trailhead Improvements project located 39 miles north of Fairbanks, Alaska, prepared by the U.S. Department of the Interior, Bureau of Land Management.

The project encompasses site demolition, grading, parking and trail construction, and installation of new facilities. Demolition work includes removal of existing vault toilets, OHV ramp, posts, culvert, kiosk structures, and decommissioning of abandoned trail sections, with estimated removal quantities for site clearing and grubbing of 1.14 acres. Construction activities involve creation of a new double vault toilet facility with 830-gallon steel tanks, resurfacing of parking areas with compacted aggregate materials (estimated 115.3 to 348.9 square feet per station), construction of a new OHV ramp with timber frame construction, and trail surfacing using 4-inch compacted aggregate. The project includes site furnishings (12 new signs, 3 sign systems to be reset, 1 GFI outlet), seeding and mulching of 0.45 acres, and plant salvage with 2,000 square feet of transplant mats. Earthwork involves approximately 2,142 cubic yards total, with specific material requirements including 6-inch bedding, 18-inch selected material base course, and 6-inch compacted aggregate surface course. Temporary traffic control utilizes MUTCD-compliant signage and barricades. The scope also includes utility location prior to construction, removal and reset of eight existing boulders, and landscape restoration to natural contours with 3:1 to 6:1 slope ratios.

NOTES

1. Site plan: Approximate finish grade contours shown. Profile and cross sections govern.

2. Do not disturb areas beyond the construction limits.

3. Provide and maintain at least one toilet at all times for public, government, and contractor use.

4. Obtain utility locates proir to construction. The Contractor is responsible for locating and protecting all utilities even if not shown on these plans.

5. Keep excavated material within the construction limits. Finish slopes to provide gradual transitions and a natural appearance.

6. When construction is complete, provide and maintain permanent erosion control measures.
