The trail opening dimensions are as follows: (see Exhibits 2 & 3).

(a) Clearing Limit - An area 8 feet wide by IO feet high.

(b) Trail Treads - A 24 inch width.

The widths are measured from the trail centerline. Where the trail is an old road, the centerline is measured from the centerline of the existing travelway, not necessarily the centerline of the old road bed.

(b) Trail tread width is that area 12 inches on either side of centerline.

Trail Maintenance

Section 982 - Logging Out

Description

982.01 Work. This work consists of removing logs, down trees and woody debris from , the clearing limits. The work described below applies to all trees, or portion of trees, that maybe in the clearing limits or trail tread. Trees are defined as the following species but not limited to - Sub Alpine Fir, Larch, Ponderosa Pine, Lodgepole Pine, Douglas Fir, Grand Fir, Cedar, Whitebark Pine, Maple, Chokecherry and Alder which are over 3 inches in diameter at the base.

Requirements

982.02 Clearing Out. Cut and remove all logs or portion of downed trees that extends across or into the clearing limits (see Exhibits 2, 3, 4, & 5). The portions of cut logs that remain on the upper side of the trail shall be either firmly anchored to prevent sliding or rolling onto the trail way or moved across the trail to the lower side and scattered outside the clearing limits. Any limbs from downed trees or logs that extend into the clearing.

limits shall be cut flush.

Fell all trees over 4 inches in diameter at the base that are leaning into the clearing limits and that are within IO feet above the trail bed. Stump height of leaning trees that are cut outside the clearing limits shall not exceed three (3) inches as measured on the uphill side of the stump.

Remove roots and stumps from trees within the trail way that have been uprooted.

Stumps requiring blasting for removal shall be left and the COR notified of the problem.

Contractor shall not reroute the trail around windfalls, uprooted trees, or other obstacles.

Ramp or reroute sections of the trail tread that have been damaged by uprooted stumps as necessary to provide safe passage on the trail.

Remove sticks or wood chunks exceeding 1 inch in diameter and 18 inches in length that have fallen on to the trail bed.

Scatter the down trees on the lower side of the trail way outside the clearing limits. Do not place such materials in stream channels, drainage ways, ditches, culvert catch basins, or other locations where they would prevent the free flow of water away from the trail bed.

Section 983 - Danger Tree Removal

Description

983.01 Work. This work consists of felling, bucking, and limbing trees and scattering slash.

Requirements

983.02 Danger Trees. Remove trees and snags that are in a leaning, unstable position over the trail way (see Exhibit 5). If any portion of such tree is within 10 feet over the trail tread, the entire tree shall be cut at the root collar and removed from the clearing limits. Cut danger trees so that stump heights do not exceed three (3) inches as measured on the uphill side of the stump. Do not leave felled trees parallel with the trail unless there are sufficient barriers to keep them from rolling or sliding onto the trail. Lop limbs to reduce slash concentration and scatter the clearing debris outside and below the clearing limits. If the trunk, or a portion thereof, falls within the trail way, remove that portion within 4 feet of either side of the trail centerline and scatter a minimum distance of 4 feet beyond and below the trail centerline.

Where the trail bed consists predominantly of rock with little or no soil present, remove all loose rock larger than 4 inches.

Fill any holes remaining from rock removal with suitable material and compact. If the rock removed is not needed for other items of maintenance work, scatter the rock by side casting to the lower side of trail way beyond the clearing limits, and distribute rock to ensure that no blockage of drainage or creation of a windrow occurs.

The location of any slides exceeding these dimensions shall be brought to the attention of the COR as soon as practical. This work does not apply to those sections of trail where the trail tread shoulder has been washed out or has slipped.

If slides exceed an average of 18 lineal feet per mile per trail, notify the COR or Inspector. For example, Butte Creek- 6.7 miles. So 6.7 X 18 = 122.4 (122 feet).

Requirements 987 .02 General. Conserve and use suitable material from the slide on the trailbed for tread surfacing. Spread this material at a maximum depth of 3 inches for a distance not exceeding SO feet in each direction from the site of the slide.

Place all excess and unsuitable material beyond the downslope edge of the trailbed.

Uniformly spread unsuitable material to a depth not exceeding 4 inches and do not obstruct drainage. In the vicinity of water courses, deposit material outside the high water area.
