1. Drainage shall be provided at all existing drainage structures (including culverts, drainage dips, and lead-off ditches). Culverts providing drainage from road ditches shall have at least two thirds of the end area usable. Culverts in live streams or natural watercourses requiring cleaning shall have the end area fully usable.

2. Cross ditches conforming to Drawing 838-1 shall be placed at locations staked by the Government to provide drainage across the full width of the roadbed. Except as provided in 2.c herein, materials removed from cross ditches and cleaning of existing drainage dips shall be bermed downgrade on the roadbed. Cross ditches shall be angled and shall discharge at points of least fill height or on natural ground. Cross ditches are considered incidental under Pay Item 838(1).

When ordered by the Government, Driveable Drain Dips (conforming to Drawing 838-6) shall be placed at staked locations to provide free flowing drainage of surface water across the full width of the roadbed. Suitable road surfacing materials removed from lead off ditches and drain dips shall be placed downgrade on the roadbed, as shown in Drawing 838-6.

3. When ordered by the Government, the existing traveled way and shoulders, including any turnouts, shall be bladed and shaped to produce a surface which is consistent to grade, and crowned or cross-sloped as indicated by the character of the existing roadbed.

Roadbed width in excess of twelve (12) feet shall be shaped only as needed to provide drainage away from the traveled way. Established grasses and other vegetation shall not be removed from the excess width except as incidental to providing drainage.

c. Intersections (See Drawing 838-2)

Intersections shall be cross ditched to drain over the full width of the listed road and define the traveled way of the adjacent road. Material removed from this cross ditch shall be placed as a berm on the roadbed and traveled way away from the intersection. A second cross ditch conforming to Drawing 838-1 shall be placed within sight of the intersection when possible, but in no case more than one hundred feet (100') from the intersection.

23 | P a g e

d. Objects on Roadbed (See Drawing 838-3)

1. Upon completion, no object extending over four (4) inches above the road surface shall remain within a ten (10) foot usable traveled way width. Larger objects shall be selectively removed or repositioned to provide the usable width and lateral clearance required (See Drawing 838-3). The usable width shall be centered on the roadbed or positioned away from the fill slope.

2. Logs and down trees shall be cut to provide not less than twelve (12) feet of opening for vehicle passage provided the remaining ends are in ground contact and do not interfere with drainage. The portion to be removed may be cut into chunks or left as one piece and placed in a stable position where it will not restrict drainage or vehicle passage. Limbs shall be selectively removed to provide stability or ground contact and shall be scattered downslope outside of the roadbed and drainage ways.

3. Rocks and other objects outside the ten (10) foot usable width may remain if drainage is provided from the road surfaces.

e. Slough and Slides (See Drawing 838-4)

1. Slough and slides may be left in place when surface drainage is provided for and at least ten (10) feet of width is available for vehicle passage. The roadbed immediately upgrade shall be cross ditched.

Any roadside ditch between the cross ditch and the remaining materials shall be filled and shaped to drain.

2. The Contractor may reposition or ramp over slides and slough when the traveled way is less than ten (10) feet (See Drawing 838-4), providing the material is capable of supporting vehicles. Ramp profile gradient shall not exceed twelve (12) percent nor have an out slope exceeding six (6) percent.

Ramped crossings shall be drained and bermed to a height of at least six (6) inches on the out side of the ramped area.

3. Slough or slide materials which are not capable of supporting a vehicle shall be repositioned on the roadbed to provide the ten (10) foot width unless the Government orders it removed under Section 832.

f. Slumps (See Drawing 838-5)

1. The roadbed immediately upgrade of slumps shall be cross-ditched (See Section A-A of Drawing 838-1).

2. Slumps at the edge of the roadbed shall not be considered a part of the usable width. Usable width may be reduced to eight (8) feet provided a berm of at least six (6) inches in height is placed on the undisturbed roadbed to divert surface water and provide a curb on the downhill side.

3. Roadbed slumps shall be ramped on both ends onto undisturbed roadbed to provide at least eight

(8) foot usable width. No material shall be placed on the slumped area. Removed materials shall be bermed on the roadbed to guide vehicles to the ramp location, used to block any abutting ditches, and to divert water from entering the slump area. Ramp profile gradient shall not exceed twelve (12) percent. Areas within the slumps that could pond water shall be drained.

4. Roadbed cracks shall be sealed with native soil and wheel or tamper compacted to reduce the introduction of surface water.

g. Cutting Vegetation

1. Trees, brush and limbs shall be cut and removed to provide at least twelve (12) feet of usable width centered on the existing usable road surface.

24 | P a g e

2. Encroaching limbs shall be removed to a height of ten (10) feet above the traveled way surface extending into the passageway from the side. Limbs extending laterally into the twelve (12) foot width shall be cut within six (6) inches of the trunk. Limbs extending down into the ten (10) foot height limitation may be cut or lopped as needed to meet the height requirement.

3. Brush and trees within the twelve (12) foot usable width corridor shall be cut parallel to and within two (2) inches of the traveled way surface.

4. Materials shall be scattered downslope outside the roadway.

h. Earth Barricade (See Drawing 836-6)

1. Earth barricades shall be constructed in locations specified in accordance with the attached drawings.
