Maintenance Needs:

Pre, During and Post haul Prior to start of operations purchaser will ensure roads are maintained and water control structure function is in place.The purchaser will be restricted from using the roads at the time it is determined that unacceptable road damage could occurred. Use may resume at such time as the road conditions improve and , if necessary, the road promptly repaired. Unacceptable road damage ocurrs on gravel roads when a maximum of 1-inch ruts occur or when contamination of the existing aggregate base or surfacing occurs.Unacceptable road damage ocurrs on native surface roads when a maximum of 4-inch ruts occur. No blading of material off the road running surface, such as into adjacent vegetation or trees, or over fill slopes will be allowed.

Existing temporary roads may be used as temporary roads by the purchaser in order to efficiently harvest the sale. No new temporary roads will be authorized in existing meadows, however new temporary roads in forested areas may be individually approved.

Temporary roads or any temporary roads used during the harvest operation shall be decommissioned (inactivated) by the purchaser as directed by the Forest Service after timber hauling is completed.

Decommissioning shall consist of the following work: ripping the roadbed to a minimum 4” and maximum 6” depth, slashed-in, seeding with enclosed seed mix, and constructing nondrivable waterbars at locations approved by the Forest Service. The nondrivable waterbars shall be constructed as per attached drawing and as per the enclosed spacing table.

The operator shall maintain Forest Service Roads used in conjunction with operations as herein outlined:

1) Keep drainage channels, ditches, and culverts clear of debris and functioning as intended.

2) Repair fences, gates, cattle guards, culverts, bridges and other structures to standard specifications if damaged during harvest or haul operations.

3) When road condition warrant purchaser shall blade and shape surface and shoulders to maintain a suitable riding surface. Earth and debris from side ditches, slides, or other sources must not be left on the road or mixed into the surface portions of the road. Blading shall not undercut banks. Gravel or other selected surface material shall not be bladed off the surface of the road. Material from slides or other sources requiring removal from the road shall not be deposited in streams or stream channels or at locations where it will wash into streams and cause damage through silting or obstruction of the streams or reservoirs.

4) All maintenance shall be performed as needed, in a timely manner or when directed by the Forest Service. In addition, at the end of each operating season, maintenance work shall be performed to minimize damage from adverse weather. Such work shall include final blading to remove ruts and other irregularities that would prevent normal surface runoff, and final clearing of ditches and culverts to ensure satisfactory functioning of the road drainage system.

SPECIFICATION T-800 DEFINITIONS

Wherever the following terms or pronouns are used in Specifications T-801 through T-811, the intent and meaning shall be interpreted as follows:

800-1.1 - Agreement. Maintenance projects require a mutually acceptable method to resolve the problems which arise when incompatible situations arise between drawings and specifications and actual conditions on the ground to allow orderly and satisfactory progress of the maintenance.

These specifications have been developed in anticipation of those problem areas and have provided that such changes will be by Agreement.

It is intended that drawings and specifications will govern unless "on-the-ground" conditions warrant otherwise, when specifications call for "Agreement", "agreed", or "approval" such Agreement or approval shall be promptly confirmed in writing.

800-1.2 - Annual Road Maintenance Plan. A plan prepared by various users of one or several roads. The plan is an Agreement on maintenance responsibilities to be performed for the coming year.

800-1.3 - Base Course. Material used to reinforce Subgrade or, as shown on drawings, placed on Subgrade to distribute wheel loads.

800-1.4 - Berm. Curb or dike constructed to prevent Roadway runoff water from discharging onto embankment slope.

800-1.5 - Borrow. Select Material taken from designated borrow sites.

800-1.6 - Crown, Inslope, and Outslope. The cross slope of the Traveled Way to aid in drainage and traffic maneuverability.

800-1.7 - Culverts. A conduit or passageway under a road, trail, or other obstruction. A culvert differs from a bridge in that it is usually entirely below the elevation of the Traveled Way.

800-1.8 - Drainage Dip. A dip in the Traveled Way which intercepts surface runoff and diverts the water off the Traveled Way. A Drainage Dip does not block the movement of traffic.

800-1.9 - Drainage Structures. Manufactured structures which control the runoff of water from the Roadway including Inslope, overside drains, aprons, flumes, downdrains, downpipes, and the like.

800-1.10 - Dust Abatement Plan. A table which lists the road, dust palliative, application rates, and estimated number of subsequent applications.

800-1.11 - Lead-off Ditches. A ditch used to transmit water from a Drainage Structure or Drainage Dip outlet to the natural drainage area.

800-1.12 - Material. Any substances specified for use in the performance of the work.

800-1.13 - Prehaul Maintenance. Road maintenance work which must be accomplished to maintain the roads to a satisfactory condition commensurate with the Purchaser's use, provided Purchaser's Operations do not damage improvements under B6.22 or National Forest resources and hauling can be done safely. This work will be shown in the Annual Road Maintenance Plan as provided in C5.31#.

Prehaul Maintenance work the Purchaser elects to perform will be in compliance with the Road Maintenance T-Specifications.

800-1.14 - Roadbed. The portion of a road between the intersection of Subgrade and sideslopes, excluding that portion of the ditch below Subgrade.

800-1.15 - Road Maintenance Plan. A table which shows applicable road maintenance specifications to be performed by Purchaser on specific roads.

800-1.16 - Roadside. A general term denoting the area adjoining the outer edge of the Roadway.

800-1.17 - Roadway. The portion of a road within the limits of excavation and embankment.

800-1.18 - Shoulder. That portion of Roadway contiguous with Traveled Way for accommodation of stopped vehicles, for emergency use, and lateral support of base and Surface Course, if any.

800-1.19 - Slide. A concentrated deposit of Materials from above or on backslope extending onto the Traveled Way or Shoulders, whether caused by mass land movements or accumulated ravelling.

800-1.20 - Slough. Material eroded from the backslope which partially or completely blocks the ditch, but does not encroach on the Traveled Way so as to block passage of traffic.

800-1.21 - Slump. A localized portion of the Roadbed which has slipped or otherwise become lower than that of the adjacent Roadbed and constitutes a hazard to traffic.

800-1.22 - Special Project Specifications. Specifications which detail conditions and requirements peculiar to the individual project.

800-1.23 - Subgrade. Top surface of Roadbed upon which Base Course or Surface Course is constructed. For roads without Base Course or Surface Course, that portion of Roadbed prepared as the finished wearing surface.
