CONSTRUCTION NOTES

1. Exhibit: “Reconstruction Quantities by Trail”: This exhibit shows quantities of waterbars and treads reconstruction on project trails. A field review done in the fall of 2007 was used to determine these quantities. Staking will be done in May or early June after snow melt. This spreadsheet will be used in lieu of a construction survey.

2. 922 (01) Native Log Waterbars: Waterbars will be constructed using native peeled and limbed, sound, free-of-defect onsite materials. Rock waterbars may be substituted for native log waterbars where suitable material is available. Reference SS 911-Clearing and Grubbing for

Part 1, Page 5 of 16 planning native waterbar rendering from local timber sources. Contractor is responsible to utilize as much of each felled tree as is practicable in producing waterbars. Variation in diameters of waterbars are SHOWN ON THE DRAWINGS. An allowance will be made for variation outside standard 6-8” minimum diameters to better utilize selected, felled trees; allow for natural taper; and minimize the number of felled trees. See Drawing 922-2(a).

3. 982(01) Logging Out: Warm Springs Creek Trail #103, North Terminus. Rombo Fire burned downstream of Trail Junction #103 & #205. The closest physical terminus is a trail ford on Warm Springs Creek with a footlog in place. Trail #103 logout starts at this ford and proceeds to the south trail terminus at the junction of Trails #103, #248 and #673.

912.01 Work. Work consists of the excavation and placement of excavated material, regardless of its nature, from within the trailway or from other sources, except for material included under other pay items AS SHOWN IN THE SCHEDULE OF ITEMS.

Includes excavation, embankment, and backfill construction required to shape and finish the trailbed, ditches, backslopes, fill slopes, drainage dips, trail passing sections, and turnouts. Also includes excavation and embankment work required to construct shallow stream fords and gully crossings, talus and rubble rock sections, and climbing turns.

Materials

912.02 Requirements. Use materials meeting the requirements of the following sections:

961 - Rock, Grid Pavement Units, and Aggregate 962 - Materials for Timber Structures 964 – Geosynthetics

Construction

912.03 Use and Disposal of Excavated Material. Conserve and use all suitable material for specified work. Conserve excess excavated rock suitable for specified project work and use in place of materials from designated sources.

Remove all duff and debris from the trailway limits and uniformly spread outside the clearing limits, not more than four (4) inches in depth (unless otherwise SHOWN ON THE DRAWINGS). Do not obstruct drainage or create piles, berms, or windrows of debris.

Place excess and unsuitable excavation beyond the downslope edge of the trailbed. Do not obstruct drainage and spread to a depth not exceeding four (4) inches. This includes any material removed in the grubbing operation and deposited in the same area.

Place rocks over four (4) inches in greatest dimensions not used in construction beyond the hinge point on the downslope side. Place rocks so that the tops are at least six (6) inches lower than the trailbed surface. Ensure that no blockage of drainage or creation of a windrow effect occurs.

Part 1, Page 8 of 16

Construction

912.04 Trailway Excavation and Embankment. Minor deviations of plus or minus 12 inches in vertical alignment and 12 inches in horizontal alignment with smooth transitions of at least 30 feet on each side of the deviation are acceptable unless otherwise

SHOWN ON THE DRAWINGS.

Construct embankments with suitable compacted material. Compact all disturbed soil within the trailbed area.

Remove any rock within or above the backslopes that is unstable. Use or dispose of rock in accordance with Subsection 912.03.

Leave the finished slope in a uniform and roughened condition.

Make necessary adjustments of horizontal or vertical alignment, within the tolerances specified in this subsection, to produce the designed trailway section and balance earthwork. Such adjustments shall not be considered as changes.

Construct a rolling dip to include an upgrade excavation of the trail subgrade; a reverse grade section with crown; and a downgrade, feathered, fill section. The transition from upgrade approach, through reverse grade and onto downgrade approach will be of sufficient length to be smooth as SHOWN ON THE DRAWINGS. See Standard Drawing 912-5, Rolling Dip.

912.05 Trailbed Finish. Fill holes with suitable material, compact, and cut high points to provide a uniform trailbed finish.

912.06 Talus or Rubble Rock Sections. Through talus or rubble rock slide areas, fill all voids with suitable material to the depth SHOWN ON THE DRAWINGS. Use cap rocks that weigh a minimum of 130 pounds and have a length of at least twice their width. At least 50 percent of all handplaced outer rocks should weigh a minimum of 130 pounds.

Construct tread by building out rather than by removing material from the inner bank.

912.07 Ditches. Construct ditches to be free of loose rocks, roots, sticks, and other obstructions. Where necessary to provide uninterrupted drainage, a leadoff ditch shall be constructed from the end of a drainage structure AS SHOWN ON THE DRAWINGS. It shall be of sufficient depth and length to insure that water flows freely from the end of the drainage structure. The ditch bottom shall have a minimum nine (9) inch width, flat and with sides finished to 4:1 slope ratio. See Standard Drawing 912-2(a), Trailbed and Slope Finish.

912.08 Geosynthetics. Where SHOWN ON THE DRAWINGS, place geosynthetics flat and parallel to centerline of the trail before placing embankment. Overlap geosythetics a minimum of 24 inches. Install anchors or fasteners as recommended by the geosynthetic manufacturer.

Part 1, Page 9 of 16

912.09 Sump Holes. AS SHOWN ON THE DRAWINGS, construct a sump hole in places where uninterrupted drainage cannot be provided at the end of a leadoff ditch. The sump hole will allow water to flow freely from the end of the ditch. Accumulated runoff water will seep into the ground and sediment will be allowed to accumulate in the sump hole. Dimensions: Two (2) feet wide x two (2) feet length x one (1) foot depth.

A sump hole will be finished with a backslope ratio equal to that required for ditch construction AS SHOWN ON THE DRAWINGS. Remove any rock on the backslope which is unstable in order to fashion a uniform slope. Remove all duff and debris from the sump hole. Place unsuitable excavation beyond the downgrade edge of the hole a distance of three (3) feet, spread to a depth not exceeding four (4) inches. Any clearing activity required for construction will not cause damage to adjacent trees. Cut limbs and branches flush with the tree trunks or stems or cut off at the ground surface. Clearing slash should not be placed in piles. Scatter all debris on the downgrade side of the hole, three (3) feet from its edge. Limb all felled trees to four (4) inch diameter.

SPECIAL PROJECT SPECIFICATION

SECTION 982 - LOGGING OUT

Description Delete this specification in its entirety and replace with the following:

982.01 Work. This work consists of removing logs, down and leaning trees from the trail clearing limits; removing loose rock and woody debris from the trail tread; as well as cleaning existing drainage facilities including culverts, ditches, water bars and drainage dips.

Requirements

982.02 Clearing Out. If any portion of a downed tree or log lies across the trail centerline or protrudes into the trail clearing limits, the downed tree or log shall be cut off at or beyond the edge of the clearing limits. If the downed tree or log is entirely within the clearing limits, it shall be entirely removed from the clearing limits.

The portion of cut tree or log that remains on the upper side of the trail shall be either firmly anchored to prevent sliding or rolling onto the trail tread or moved across the trail to the lower side and scattered outside the clearing limits. Scatter the down trees on the lower side of the trail tread outside the clearing limits. Do not place such materials in stream channels, drainage ditches, culvert catch basins or outlets, or other locations where they would prevent the free flow of water away from the trail tread.

Remove loose roots and stumps from trees that have been uprooted within the trail clearing limits and do not require blasting.

982.03 Leaning trees (live or dead). Any leaning tree, regardless of the location of its root system, which enters the trail clearing limits shall be cut off at the ground level and shall be treated as a downed tree and handled in accordance with 982.02 above.

982.04 Rerouting. Rerouting the trail around windfalls, uprooted trees, and other obstacles will not be permitted. Ramp or reroute sections of the trail tread that have been damaged by uprooted stumps as necessary to provide short-term, safe passage on the trail. Notify COR as soon as practicable with detailed location. Payment for such work will be incidental to the specified work item and no extra payment will be made.

982.05 Wood debris. All loose wood debris including, but not limited to limbs, branches, and other tree remnants larger than 3 inches diameter and 18 inches length that have fallen on the trail tread shall be removed from the tread.

982.06 Soil and debris slides. All slides along with their location shall be brought to the attention of the COR as soon as practicable.

Part 1, Page 15 of 16

982.07 Loose rock removal. All loose rock 6 inches or greater in any dimension, except those so large as to require blasting, shall be removed from the trail tread and scattered by sidecasting to the lower side of the trail tread outside the clearing limits.

Distribute rock to ensure that no blockage of drainage or creation of a windrow occurs.

Do not dispose of waste material in water courses. Any rock too large to remove shall be reported to the COR as soon as practicable. Remove any loose rock in drainage dips or ditches that may impede water flow off the trail.

Loose rocks are rock that are not firmly embedded in the trail and can be removed by hand.

982.08 Drainage maintenance.

Turnpike maintenance. Remove debris and soil from culvert catch basins; inlet and outlet ditches; and from inside culverts to permit the unobstructed flow of water into, through, and away from the culvert. Remove debris and soil from side ditches and leadoff ditches and restore ditches to original design standard, as needed.

Waterbar maintenance. Accumulated dirt, rock, and debris shall be removed from the upgrade side of all water bars and deposited on the downgrade side of the water bar to bring the trail tread flush with the top of those water bars. Material shall be removed for a minimum of 2 feet width upgrade from the water bar. The 2 foot width shall begin at the inside edge of the trail tread and extend to the outside end of the water bar, measured on the upgrade side. Clean debris away to 1/2 the diameter measurement of the water bar structure. This excavation should be sloped gradually and meet the water bar at its centerline. Clean any leadoff ditches to their original design standard and "open to daylight" to permit water to flow freely from the trail tread.

Drainage dip maintenance. Clean deposited material and restore drainage dips to original design standard. Remove all debris from the leadoff area of dips to permit water to flow freely from the trail tread. Use suitable material obtained by cleaning dips for fill on the downgrade side, removing rock more than 3 inches at its greatest dimension. Compact all material placed in the trail tread.

Measurement

982.09 Method. Determine the quantity of logging out units by measuring the slope distance along the trail centerline or by actual count of those units designated for removal.
