Project Name Primrose Trail Reconstruction

General Information

1.0 Background and Purpose

This is a non-personal services contract to provide deferred maintenance services along an approximately 5-mile segment of Primrose Trail, on the Seward Ranger District, Chugach National Forest. General maintenance issues include extensive mud and poor drainage in low-lying sections, overly challenging and steep/eroded terrain requiring a reroute. The finished product following the completion of this contract will be a trail brought to USFS Class 3 Bicycle Design Parameters (Attachment 6, page 5), that can be sustainably maintained and is enjoyable for the public.

Period of performance June 1, 2024 – November 1, 2026

2.0 Scope of Work

This project is for extensive reconstruction and deferred maintenance of a 5-mile section of the Primrose Trail on the Chugach National Forest (CNF). A detailed list and descriptions are provided in Section 4.0, but a brief summary of the major work items include:

• Trail reconstruction consisting of 5 miles of brushing & general restoration (clearing, tread rehabilitation, removing protrusions, among others)

• Replacement of puncheon, turnpikes, drainage structures, and repair of stream fords.

• Over 4,000 LF of resurfacing existing trail surface (using D-1 aggregate, 6” depth).

• Obliteration of 1,347 LF of existing steep/eroded trail – average grade of around 30% at times.

• Construction of 1,368 LF of new trail, 36”-60” wide, with associated culverts (12”), puncheon, and over 1,000 LF of D-1 surfacing. New trail corridor will be through largely uplands territory with a grade up to 15%.

The breakdown is described below:

Base Bid:

• Mobilization

• Staking

• All trail work, excluding the re-route and obliteration (stations 245+00 to 258+68 on Work Log). These items will be broken down by individual task as shown on the Schedule of Items.

• Trail re-route and obliteration (stations 245+00 to 258+68 on Work Log)

3.0 Location

3.1 The project location is approximately 13 miles south of the community of Moose Pass. All work will be accessed from the Primrose Trailhead located at the end of Primrose Spur Rd (60.34°N; 149.37°W), near mile 17 of the Seward Highway. There is a large parking area at the end of the road near a boat launch, and a smaller access drive through the Primrose Campground. Contractor parking and staging is likely to be primarily in the boat launch parking lot. Access to the trailhead is gained by passing through the campground.

Boat launch must remain open and accessible to the public, no more than ¼ of the parking lot may be used to stage equipment, staging may only happen for 24 hours in a given week or as approved by COR.

3.2 While clearing and restoration work begins at the trailhead, the major work tasks begin approximately 0.5 miles from the trailhead.

3.3 There are no utilities available at the site. Cell-service is intermittent and unpredictable within the project area.
