15.4 – Erosion Control

15.4.1 Description.

The work consists of furnishing, constructing, and maintaining permanent and temporary erosion and sediment control measures.

15.4.2 Construction Requirement.

Prior to the start of construction, submit a general plan that provides permanent and temporary erosion control measures to minimize erosion and sedimentation during and after construction. Do not begin work until the necessary controls for that particular phase of work have been implemented. Do not modify the type, size, or location of any control. An alternate erosion control plan shall be submitted to the CO for approval. Incorporate all permanent erosion control features into the project at the earliest practicable time, as outlined in the approved plan. When erosion control measures are not functioning as intended, immediately take corrective action.

For individual sites identified in the Task Order, site specific erosion control plans will be required.

Erosion control plans will vary by site. Each site must be evaluated on a site by site basis and an appropriate plan submitted and approved. Contract Drawings (Sheet 5 of 5) provides an example of the type of temporary erosion control plan that might be used at large live or intermittent stream crossings. Depending on site conditions, erosion control plans may be more or less extensive than the sample provided.

All erosion control plans shall be approved before notifying the CO of any desired start work on any crossing requiring an erosion control plan. Allow Forest Service 7 business days to review any plans submitted. The Contractor shall notify the CO at least 72 hours prior to start of instream work at sites designated in the Task Order. The Contractor shall also notify the CO at least 72 hours prior to any

Stream Channel Restoration work.

15.4.3 Measurement and Payment

Do not measure Erosion Control for payment. Compensation is made as an indirect payment to

Mobilization or other pay items requiring site specific control.

20.1 - Road Treatment

20.1.1 Description.

This work consists of modifying or eliminating the roadway prism as specified in Task Order. The work consists of excavating and placing material within the roadway prism by constructing Cross

Ditches, removing Ditch Relief Culverts, constructing and reconstructing ditches, shaping of roadway, and scarification, as specified in the Task Order. See Contract Drawings (Sheets 1 and 5).

20.1.2 Construction Requirements.

Limit disturbance to soils and vegetation. Slope all areas to drain and return water to natural watercourse. After removing drainage structures on intermittent or perennial stream channels, obtain inspection and acceptance from CO before continuing work.

Dispose of fill material excavated from areas infested with noxious weeds in a manner which minimizes the potential spread of the weeds.

Scarify to a minimum depth of 18 inches, except for areas where bedrock is encountered, and under all areas where disposal is placed, except where rock or hardpan is encountered.

Slash and clearing debris shall be utilized in the area that it is produced. Treat slash and clearing debris by scattering on finished disturbed slopes in the following order of priority:

1) Side slopes of pipe removals (stream channels) or channel margins as approved by CO:

2) Outslope surfaces

3) Pullback surfaces

4) Disposal surfaces

Distribution of slash and clearing debris shall allow for a 3 to 5 feet wide foot access for the entire length of the project.

(a) Cross Ditches:

Cross ditches shall be constructed so as to intercept and channel water away from existing ditch lines and across the road to a stable location outside of the road shoulder. All cross ditches shall be constructed with bottom width of 3 feet, and 2H:1V side slopes, unless otherwise specified.

The existing ditch shall be shaped and blocked to direct water into the cross ditch. Cross ditches shall be skewed with the outlet in the downgrade direction. When cross ditches drain onto side cast material or erodible fill slope material, erodible material at the outlet shall be pulled back to stable ground up to

20 feet slope distance from shoulder where specified in the Work List. Erodible outlet locations shall be armored with rock (riprap) where specified in the Work List. See Contract Drawings (Sheet 1 of 5) for size, shape, skew, depth, grade and additional details.

Cross Ditch Spacing: Cross ditches shall be constructed at springs, seeps and natural low spots

(swales), and areas that may flow or pond during wet periods unless outsloping and reshaping of the road prism shall provide the needed drainage.

Where outsloping is not required or is not feasible, cross ditches should be spaced as follows, unless otherwise directed by the CO:

Average Road Grade Spacing between Drainage Structures

0 – 3% 300 ft.

3 – 5% 200 ft.

5 – 10% 100 ft.

10% + 75 ft.

Spacing and location shall be adjusted to fit field conditions as follows:

1. Additional cross ditches may be designated by the CO on the Work List where flow or scour in ditch or at cross ditch outlet suggest significant concentration of water.

2. The interval may be adjusted up to 75 feet in order to discharge water over a less erodible surface. For example, placement of cross ditches to discharge water over rock or rock fills rather than an unvegetated soil or fill.

3. Cross ditches shall be constructed at each end of disposal sections.

4. Outlets or discharge points should take advantage of hard points and should not be directed onto loose unvegetated soil or fill.

5. Spacing will be adjusted to a minimum of the next higher road grade requirement. Where the ditch line shows signs of high flow, the road location is near the toe of slope or slope above road is sufficient to create high runoff.

(b) Ditch Relief Culvert Removal: A Ditch Relief Culvert is defined as a culvert that captures water from the ditch line and typically does not drain a defined channel.

Unless otherwise designated in the Task Order, all culverts and any culvert down-drains shall become the property of the Contractor and shall be removed from National Forest Land and disposed of in an approved facility in accordance with local laws and regulations.

Ditch Relief Culverts shall be removed in the manner specified in the Work List and detailed on the Contract Drawings (Sheet 1 of 5).

If erosion has occurred at the outlet, excavation shall extend to existing natural channel bottom or as specified in the Work List.

Limit disturbance to soils and vegetation. Slope all areas to drain and return water to natural watercourse.

Dispose of fill material excavated from areas infested with noxious weeds in a manner which minimizes the potential spread of the weeds.

(c) Ditches: Construct or reconstruct ditch line as specified in the Work List to facilitate self-maintenance operation.

(d) Shaping Roadway: Sloping and shaping of roadway shall vary to blend with undisturbed ground.

Keep excavated material within the original roadway prism.

(e) Scarification: This work consists of loosening and de-compaction of the roadway from ditch line to the outside edge of road. Limit disturbance to soils and vegetation. Slope all areas to drain.

Scarify roadbed and ditch line in areas designated in the Work List to loosen and de-compact the roadway. Scarification shall be to a minimum depth of 18 inches, except in areas where bedrock is encountered. Scarification must be done under all areas where disposal material is placed, and where specified. The scarified area must be loose and broken up, with no intact blocks larger than

6 inches by 6 inches. The resulting pattern shall not create ponding of water, or concentrate flow paths that could create erosion or gullies.

20.1.3 Measurement.

Measurement shall be the slope distance along the centerline of the road, measured to an accuracy of

100 feet per mile.

20.1.4 Payment.

The accepted quantities shall be paid at the contract unit price per unit of measurement for section

20.1. Payment shall be full compensation for work prescribed in this section, based on the final approved Work List, inspected and accepted to the nearest one tenth mile.

20.2 - Outslope

202.1 Description.

This work consists of outsloping the roadway to control drainage.

20.2.2 Construction Requirements.

Limit disturbance to soils and vegetation. Slope all areas to drain. Decommission segments of the road designated in the Work List by outsloping in accordance with the sections on Contract Drawings

(Sheet 4 of 5). Outslope will be at a minimum of 20% (Type 2) unless otherwise specified.

Outsloping in excess of 20% (Type 1) shall be applied adjacent to all streams and designated Restore

Natural Drainages as shown in the Work List.

20.3 - Fill Slope Pullback

20.3.1 Description.

This work consists of removal of unstable fill slopes in designated locations and placement of the excavated material.

20.3.2 Construction Requirements.

Fill material that are showing evidence of instability with potential of delivery to water bodies placed on slopes steeper than 70 percent or sections as specified in the Work List, shall be pulled back on to the roadway. Unless otherwise directed, excavation shall include any unstable material indicated by cracks in the outer half of roadway. The finished grading shall result in a continuous outsloping across the roadway as shown on Contract Drawings (Sheet 4 of 5).

Pullback dimensions are defined as follows. Distance 1 (D1) is the horizontal distance within the outer portion of the roadway (a point within the roadway to the outermost shoulder). Distance 2 (D2) is slope distance measured from the top of the outermost shoulder to a lower excavation limit downslope.

The maximum excavation slope distance for D2 is 20 feet, unless otherwise specified in the Work List.
