General Notes

1. Roads specified for Surface Blading, T-803, on Table One - Road Maintenance Summary and Specification List, are to be routinely bladed in accordance with Specification T-803, and the Typical Grading Sections.

2. Roads specified for Closing Roads, T-811, CT5.31 are to be closed in accordance with Specification T-811 and the following:

The surface of all roadways requiring vegetation shall be loosened to a depth not to exceed 2 inches in preparation for seeding. The loosened surface shall be of the type attained by using a blade, disc, rock rake or other method approved by the designated Forest Service Representative. Local roadways, landings and skid trails shall be seeded with the following mixture at the end of the Contractors operations:

Total 4.0 lbs./acre

Disturbed areas requiring seeding on roads to remain open (see CT5.31) shall be seeded with the above seed mixture.

Slash shall be scattered along the length of the roadway for 200 linear feet from the intersection and along the width of the roadway for 50 feet, with the intent of camouflaging the intersection.

3. In areas of high slash concentration, slash may be piled for later disposal by the Forest Service. Piles shall be placed and constructed so burning will not damage remaining trees.

4. All work required by any listed specification shall be performed when necessary, regardless of whether items are specifically shown in CT5.31 or Table One – Road Maintenance Specification List.

5. All lead-off ditches shall be constructed to a length that will freely drain the associated outsloped drain; the low point of all vertical curves shall be outsloped to drain freely.

TYPICAL GRADING SECTION – DITCHED PORTIONS

Cut slope 1:1 Fill slope 1.5:1 Ditch slope 3:1

The existing traveled way shall be maintained, the traveled way shall not be narrowed or widened. Existing ditch depth shall not be increased unless necessary to provide for adequate drainage. Crown applies to tangent portion of traveled way only. Maintain existing superelevation on curves. Clearing limits applicable to roads 22, 611, and 461.

TYPICAL GRADING SECTION

All roads Maintenance Level 2 (ML 2) and above will remain open (see Table One).

All other local roads (ML1) will be closed in accordance with T-811. (See Table One).

Clearing Limits - 16’ Minimum Roads to remain open.

Clearing and Seeding Limits - 14’ minimum Roads to be closed.

The traveled way indicated is a minimum. If the existing traveled way exceeds the indicated minimum the existing width shall be maintained, but not exceeded unless otherwise noted in the work descriptions.

T803 SURFACEBLADING

DESCRIPTION

1.1 This work shall consist of maintaining a native or aggregate surface roadbed in a condition to facilitate traffic and provide proper drainage. It includes maintaining the crown or slope of traveledway, shoulders, drainagedips; all ditches, berms and turnouts, and provides a level of smoothness appropriate for the traffic served.

REQUIREMENTS

3.1 Surfaceblading shall be performed immediately before, during and after the Purchaser's use as necessary and practicable to facilitate traffic and proper drainage.

3.2 The roadbed, including turnouts, shall be scarified if necessary and bladed to remove ruts and other irregularities and shaped. Existing aggregatesurface material shall be bladed to conserve material and to prevent segregation of particle sizes. While performing surfaceblading during routine roadmaintenance, Purchaser shall avoid permanently fouling surfaces through covering them with rocks, earth or debris from sideditches, slides, or other sources. Purchaser shall avoid blading surface material off of the roadbed.

3.3 When directed by the Forest Service, residual bituminous material from previous surfacestabilization treatments shall be scarified and reduced to produce material not exceeding threeinches (76.2 mm) in greatest dimension.

3.4 Cutslopes or designed berms shall not be undercut.

3.5 At intersections, the roadbeds of sideroads shall be graded for a reasonable distance to assure proper blending of the two ridingsurfaces.

3.6 All ditches shall be cleaned and maintained to latest constructed crosssections to provide freedrainage. Drainagedips shall be maintained to conform to details shown in the drawings.

3.7 Designed berms shall be repaired when necessary by placing selectedmaterial. Other berms, which are determined by the Forest Service as not necessary, shall be removed.

T804 OPENING AND MAINTAINING ROADS

1.1 This work shall consist of opening roads by removing closure devices, cleaning ditches, removing berms and blading the traveledway. This work also consists of maintaining the roadway immediately before, during and after the Purchaser's use as necessary to facilitate traffic and proper drainage.

REQUIREMENTS

3.1 All closure devices, such as waterbars, depressions, mounds of earth, or downedtrees, shall be removed and disposed of at locations designated by the Forest Service.

All trees and logs on the roadbed, and trees and brush that overhang the traveledway and interferes with vehicle travel shall be removed and scattered outside the roadway.

All drainagedips, ditches, outsloped or insloped sections, and other drainage devices built into the roadway shall be cleaned and maintained so they are functional.

The traveledway shall be bladed to produce a rideable surface.

No scarifying, watering, or compaction will be required to complete the work. Berms shall be removed as directed by the Forest Service.

T811 CLOSING ROADS

1.1 This work shall consist of closing roads by restoring or installing closuredevices and drainagefacilities on roads no longer needed by the Purchaser or when interim closures are required during periods of purchaser's nonuse.

Closure devices and drainage facilities may consist of crossditches, waterbars, drainagedips, barriers or gates and restoring insloped and outsloped sections.

REQUIREMENTS

3.1 During periods of Purchaser's nonuse, roads designated for interim closures shall be closed unless otherwise agreed to, in writing, by the Forest Service.

The entire roadway shall be bladed and shaped to provide drainage during periods of closure or nonuse.

Where possible, and still retaining appropriate surfacedrainage characteristics, existing surfacevegetation shall be protected during blading operations.

3.2 All drainagedips, outsloped or insloped sections, or other drainage devices built into the roadbed and roadway ditches shall be restored and replaced. Existing culverts shall be maintained to provide unobstructed flow.

Waterbars and other crossditches shall be installed at locations designated by the Forest Service.

3.3 All closuredevices and signs shall be installed by the methods and at the locations shown on the drawings or designated by the Forest Service.

3.4 Where existing surfacevegetation has been destroyed as a result of Purchaser’s operation, the entire roadway will be seeded with a seedmixture approved by the Forest Service.

T812 MISCELLANEOUS STRUCTURE

1.1 Maintenance of miscellaneous structures includes cattleguards, gates, Hbraces, fencing, guardrails, structure delineators, signs and other similar structures that have been previously installed to insure the safe and efficient operation of the road.

MATERIALS

2.1 Materials used to maintain miscellaneous structures shall be similar in type and quality to those materials in the existing structure.

REQUIREMENTS

3.1 Cattleguards - Loose rail or wing elements shall be straightened and welded or bolted backintoplace.

Excess material Carried into the cattleguard shall be removed when the drainage becomes blocked, or any time it reaches within sixinches of the bottom of the cattleguard frame.

Drainage into and out of the cattleguard shall be kept open.

3.2 Gates - Metal frame gates shall be maintained in good condition and adjusted to swing properly. Hinges and latches shall be repaired if not operating properly and hinges shall be oiled. Brush and debris shall be removed from within the swingradius.

Loose wire gate ends and internal stays shall be maintained in good condition. Gate wire shall be maintained as necessary to insure proper operation of the gate both as a vehicle passageway and as a barrier to cattle movement.

3.3 Hbraces Posts, horizontal braces, and diagonal struts or tie wires shall be maintained to provide for tightness of fence and gate or latch posts.

3.4 Fencing Fencing which has no opening or provisions for gating shall be temporarily braced prior to cutting. Fencing shall be replaced upon completion of use and shall be stretched and securely fastened to conform to its original spacing before cutting.

3.5 Structure Delineators and Signs Structure delineators, regulatory and warning signs determined by the Engineer as necessary, shall be maintained in good, clean condition.
