835 ROADWAY DRAINAGE MAINTENANCE (3/96)

1. DESCRIPTION

This work consists of providing drainage on roads that have been physically closed to traffic.

a. Access

1. The Government will provide for access through locked gates and also provide any special devices other than standard wrenches or tools, required for removal or replacement of fabricated barricades.

2. Other work associated with Contractor's access shall be the responsibility of the Contractor. The entrance shall not be left available for access to persons not associated with this contract; temporary barricades shall be used during the active performance of work.

b. Drainage

1. Upon completion of work, the roadway shall be shaped to provide for the removal of surface water, but need not be passable to vehicles. Waterbars, barriers or berms existing prior to the Contractor's operation shall be repaired or reinstalled. Areas where water is ponded by existing centerline profile sags in through cuts may be left untreated.

2. Continuous blade shaping of the roadbed is not required under this specification.

3. Work to be done at staked locations shall be as indicated on the stake.

4. Any of the following methods are acceptable for use at eroded or rutted locations.

a. Method A: Outsloping the roadbed at not less than one-half (1/2) inch per foot.

b. Method B: Insloping the roadbed at not less than one-half (1/2) inch per foot of width.

c. Method C: Water bar roadbed at locations staked on the ground. Construct in accordance with Drawings.

5. Drainage structures located in through fills and natural watercourses shall be fully functional without obstructions, including inlet and outlet channel within twenty (20) feet of the structure.

6. Culverts and other fabricated structures providing drainage from road ditches shall either be cleaned and the ditch made functional or waterbar(s) shall be provided across the roadbed. Fabricated drainage structures discharging on natural ground within three (3) feet of roadbed elevation may be removed at Government's option to provide the waterbar. Removed structures shall become Contractor's property to be removed from National Forest. Contractor-installed temporary drainage structures, if any, shall be removed and replaced with a water bar.

c. Slides, Slumps and Slough

1. Slides and slough may be left in place provided they do not potentially impound water or divert water from watercourses. Reshaping of the various surfaces shall be done as necessary to provide drainage.

2. Drainage shall be provided to effectively decrease or eliminate the entry of surface water into slides, slumps, and roadbed surface cracks. The Contractor shall place berms, waterbars, or ditches as needed to intercept and remove runoff water from the roadbed. Cracks shall be surface sealed by covering with native soil materials to prevent additional water entry and compacting with equipment tires.

d. Entrance Devices

Upon completion of work, entrance devices shall be replaced to effectively eliminate access by motorized vehicles having four (4) wheels and a width in excess of fifty (50) inches.

e. Seeding

All disturbed areas shall be seeded and fertilized in accordance with requirements set forth in Section 836 and are incidental.

3. MEASUREMENT

Measurement for the ordered and accepted work will be the length of the road in miles as shown on the Road

Listing.

835(1) Roadway Drainage Maintenance Miles
