*AQ = Actual Quantity. As stated in “Payment” section in solicitation, payment for work performed will be based on actual work completed by the Contractor and accepted by the Government.

General Scope of Work:

Contractor shall provide all labor, supervision, equipment, supplies, and incidentals to provide maintenance and restoration services for the existing designated trail to improve access to the waterfall by re-establishing the trailway. Forest Trail 115, Sill Branch North Trail, is located on the Cherokee National Forest, Nolichucky/Unaka Ranger District in Unicoi County, Tennessee. This 0.50 mile trail is a Trail Class 3, standard terra trail managed for hiker/pedestrian use only.

Conditions of the trail vary and not all sections of the trail will require work. Sections that require work will be designated on the ground and accounted for in the Schedule of Items. Specific drawings for this trail will not be issued.

The first 2015 linear feet of the Sill Branch trail was originally constructed as a road bed and is typically 6 feet in width. Maintenance and installation of the 5 drainage structures will be required to span the width of the existing tread and remove water from the trail. The majority of work is planned for the remaining 662 feet of the trail. This section is where the trail leaves the road bed after the intersection with Trail # 116, Sill Branch South.

As specified in section 915 – Existing Trail Restoration, the work consists of restoring the original trail template including some or all of the following items: clearing, removing slough and berm, borrow, filling ruts and troughs, reshaping backslopes, excavation, reshaping trail tread, restoring drainage and other trail structures, removing protruding rocks, roots, stumps, slough, berms, trees and logs. The restored trail template shall have a 36” typical tread width.

Of the estimated 662 linear feet of trail restoration listed in the Schedule of Items, approximately 100 linear feet includes work related to restoring an 8 foot wide section to 36” through excavation and

An estimated 442 linear feet will be related to clearing and grubbing, excavation and embankment, rock and root removal, slough and berm removal and excess material, reshaping and finishing trailbed and backslopes. The remaining 100 linear feet of work will restore a talus section of trail to a 24-36” tread. Work in this section will be related clearing and grubbing, excavation and embankment, reshaping and finishing trailbed and backslopes.

Native rock suitable for work listed in the Schedule of Items is available along or near the trail, but may be limited, and may require hauling in some sections. Rock sources must be approved by Contracting Officer’s Representative (COR).

Design Parameters:

The following design parameters are standardized technical guidelines that have been established for all National Forest System trails based on trail class and the designed use for the trail, i.e. hiker, equestrian or bicycle. These parameters are included in the task order to covey an overall intent for trail maintenance and restoration work. Local deviations from these parameters are expected in response to trail-specific conditions, topography and other factors. Scheduled trail restoration work and should attain these parameters unless noted otherwise. Clearing limits should be attained unless noted otherwise. Deviations must be approved by the CO.

Trail classes are general categories reflecting the desired level of trail development ranging from minimally developed (Trail Class 1) to fully developed (Trail Class 5). Sill Branch trail is designated as a Trail Class 3 with the designed use is hiker/pedestrian. The trail is closed to equestrian and bicycle use.

Design Parameters for Trail Class 3, Hiker/Pedestrian Trail

• Design tread width = 18” to 36” (36” tread typical for Conasauga Falls Trail)

• Target cross slope = 5-10%

• Design surface = intermittently rough; protrusions less than or equal to 3” may be common, but not continuous; obstacles may be common, but not substantial or intended to provide challenge

– typical 10” maximum height

• Design clearing = height 7’ to 8’ and width 36” to 60” uphill & downhill from trail center line

• Design turn = 3’ to 6’

Contract Delivery Timeframe:

Contract time will be 60 days. Notice to Proceed date will be negotiated after award of task order.

Project Location:

See attached map. The commercially available National Geographic Trails Illustrated Map #782 identifies Forest Trail 115, Sill Branch North Trail, by both trail name and number.

The project is located approximately 20 miles east of Greeneville, Tennessee. From Greeneville, take TN Hwy 107 east for approximately 15 miles. Turn right onto Clark Creek (NFSR #25). Drive approximately 3 miles and the trailhead will be on left.

Equipment Use:

Mechanized equipment designed for trail construction and maintenance is permitted on Forest Trail 115.

Equipment used to restore and maintain trails shall be sized appropriately so as not to damage to the trail and surroundings. Incidental damage caused to trails or any other natural or man-made feature shall be repaired and/or maintained to pre-existing condition.

Mobilization Considerations:

Camping may be allowed in designated dispersed camping areas in the national forest along Clark Creek (NFSR #25), but must be approved through the district. However, there are no facilities available in these dispersed camping areas. Hotels, restaurants, and grocery stores are located approximately 20 miles west in Greeneville. More information about local amenities in Greene County can be found at:

A separate item for mobilization cost is not included in the Task Order. Include these costs when pricing your work.

Trail Closures:

The trail may be closed when contractor is actively working on the trail. Any trail closures would be coordinated with the CO.
