Roadway Obliteration

Description This work consists of the reclamation of roadways by the removal of culverts; decompaction and outsloping of subgrade; placeation of waterbars and leadoff ditches; restoration of stream channels;

and seeding, revegetation, and mulching of all disturbed areas. In addition work includes diverting of live streams, pumping, bailing, draining, sheeting, bracing, and other miscellaneous items required for execution of the work.

Roadway reclamation methods are designated as follows:

(a) Method 1. Obliterate the roadway by restoring to approximate original ground contours.

Decompact road surfaces. Remove all pipes, bridges, and other structures and all associated fill material, down to “natural ground” or as shown on the drawings. Keep excavated material within the original roadway construction limits. Finish slopes to provide gradual transitions in slope adjustments without noticeable breaks. Effectively close access to area by recontouring or placement of slash.

Work Requirements Conform to the following when obliterating roads by either method.

ACCESS: All roads used for access to work shall be maintained to prevent any erosion or roadway degradation using inslope/outslope, waterbars, closures or as described in the Work Lists or as directed by the C.O.

EXCAVATION: After required decompaction of the roadway the fill material shall be pulled up and placed on roadbed between the top of cut and original ground forming a slope approximating natural contours or 20% as designated. No ditches, water traps, or berms shall remain. Finish to the lines shown on the plans blending to the surrounding terrain.

DECOMPACTION: Any hardened road segment or surface area shall be decompacted to promote water infiltration and establish vegetation. This work shall consist of loosening all of the soil in the existing roadbed or landing surface to a depth of 18 inches and a clod size no larger than 10 inches or as shown on the plans.

OUTSLOPING: Roads and landings shall be outsloped by decompacting the surface as specified above and by pulling the fill shoulder towards the cut bank as shown in the plans.

Excavated material shall be spread over the roadbed or landing. The finished grade shall be a sloping surface across the existing roadway to the grade specified on the drawings and shall be a free draining. Any existing ditches at the toe of the cutslope shall be ripped and filled with the material excavated during outsloping. Any berms remaining along the upper or lower edges of this work shall be blended with the surrounding terrain. All other berms, tracks, and other surface irregularities shall be reshaped to allow a free draining surface.

DRAINAGE EXCAVATION: Drainage excavation shall include the removal of all fill and bedding material, the restoration of the natural channel and blending of sideslopes. Stream channel width and dimensions after drainage structures have been removed shall be the same as the undisturbed width and dimensions above or below the crossing. An approximately uniform grade shall be created from natural ground above the inlet to natural ground below the outlet to facilitate a free draining channel for the entire length unless otherwise noted on the worklists.

Excavated material shall be incorporated in the adjacent areas while maintaining “natural slopes”. If live water is encountered a stream grade channel or a cross drain channel is needed.

REMOVAL OF STRUCTURES: Remove all drainage structures (culverts, downpipe, anchors, drop inlets, and trash racks, log culverts etc.). Remove all existing gates and barriers on the project road also. All items removed, except log culverts, shall become the property of the contractor and be removed from government land and recycled or disposed of in a legal manner. The material or structure designated for removal shall include it and all of its appurtenances and hardware. Material from log drainage structures can be used as slash placement on recontoured roadway outside of channels.

VEGETATION REMOVAL: This work shall consist of clearing, grubbing, removing and disposing of vegetation. Vegetation includes dead woody debris, trees, stumps, roots and other vegetation within the limits of the project area necessary to be cleared for access to the project sites, covering areas designated for excavation or embankment, and woody material generated from excavations. Vegetation shall be preserved and placed on top of recontoured road segments and completed channel side slopes in stable positions not interfering with stream channel flow. The disturbed area shall be 50% to 75% covered with natural slash when available from roadway. Excess material will be windrowed along the bottom edge of the original roadway construction limits with breaks for game passage every 200’. A walkable trail shall be left along the upper edge. Disturbed vegetation shall not be left "hung-up" in remaining live vegetation.

CLUMP PLANTING: Clump planting from available vegetation along the clearing limits shall be completed throughout the recontouring at a minimum of 6 plantings per 100 lineal feet.

This will be accomplished with an excavator and the clump shall be of sufficient size to maintain all the root system and contain adequate soil to enhance favorable growth. Duff material shall be scraped from above the top of the cutslope and scattered along the completed recontoured road. This duff material may consist of a combination of needles, organic material, plants, decomposing stumps and logs.

Channels and Structures.

Place the following as shown in the drawings when noted on the work lists or directed by the C.O.

STREAM GRADE CHANNELS (SGC): These are either live stream channels or draw crossings. Removal of all fill material and recontouring to the original natural contours is required.

A pipe will be required for crossing live streams while accessing the project. If there is no existing culvert a temporary one will be required before proceeding.

Stream Diversions or dewatering is required while work is being done in the channel. These may be done with pipes, open ditches or check dams. The intent is to minimize the amount of erosion during work.

Place temporary sediment dams instream below all work using straw bales. Place bales in channel below high water, breaking bales if necessary to provide a tight fit. After channel restoration, remove trapped sediment from stream and place above high water. Break bales and spread wet straw on the adjacent slopes.

Live streams will require a minimum of two grade control structures. Wider crossings may require more, using a 20’ maximum spacing. These are usually formed with rocks as shown on the plans. Logs may be substituted as long as shape and elevation can be maintained.

Channel slopes shall be stabilized with slash, straw mulch. Transplant forbs and sedges along the channel slopes.

No material will be placed in the channel bottom that would divert stream and cause erosion.

DRIVEABLE WATERBAR: Place temporary driveable waterbars as shown on the drawings.

Place on all cleared access roads and as described in work lists or as directed by the CO to prevent surface erosion during the working period. When the access road is to remain the waterbars are to be placed as permanent.

CROSS DRAIN CHANNELS (CDC): These are areas where springs or seeps in the cutslope are evident or noted. Remove the fill material below the slope but do not place the excavated material in seep or spring. Create a channel to provide drainage onto natural ground as shown on the drawings. The slope of the banks shall be a minimum of 3:1. Transplant forbs and sedges along the channel slopes and in the channel bottom. Place wetland vegetation in strips across the bottom of the CDC at 4-8’ spacing to encourage subsurface flow.

Vegetation mats consist of spongy wetland plants and vegetation collected in long strips with the excavator bucket from nearby wetlands or ditchlines and spread in bucket wide widths perpendicular across the CDC or drainage at 4’ to 8’ spacing. These encourage percolation and subsurface flow.

GRADE CONTROL STRUCTURES: Place Grade Control Structures at live water crossings as shown on the drawings. Place as directed above and when noted on the work lists or as directed by the C.O.

Soil Erosion Control.

This work consists of furnishing, placeing, and maintaining permanent and temporary erosion and sediment control measures to minimize erosion and sedimentation during and after work according to the contract permits and this Section.

When working adjacent to live water or streams a buffer of vegetation, a brush barrier, or straw dike will be maintained to prevent direct sedimentation to the stream.

Store and handle material to preserve its quality and fitness for the work. The Contractor is responsible for the security of all stored material.

Straw bales. Provide 10 straw bales from a certified noxious weed free source. Furnish bales tied with either commercial quality baling wire or string. Conform to the following:

(1) Approximate length 3.5 feet

(2) Shape rectangular

(3) Approximate mass 70 pounds

Use straw bales and brush barriers for filtering sediment from runoff and reducing the velocity of sheet flow. Conserve brush from clearing operations to form brush barriers.

Maintain temporary erosion control measures in working condition until the project is complete.

Restore the ground to its natural or intended condition and provide permanent erosion control measures when temporary measures are no longer needed. Clean erosion control measures when half full of sediment. As work in the area is completed the bales shall be broken and the straw spread as a mulch.

Soil erosion control measures will be evaluated by visual inspection of the work for compliance with the contract. Contractor must provide certification of weed free materials. Work may be rejected at any time if it does not to comply with the contract.

Seed and Mulch This work consists of seeding the full length and width of the decompacted roadway and all other disturbed areas. Hand-operated seeding methods are satisfactory on areas inaccessible to mechanical equipment.

Store and handle material to preserve its quality and fitness for the work. The Contractor is responsible for the security of all stored material.

Conform to the Federal Seed Act, the Federal Noxious Weed Act, and applicable State and local seed and noxious weed laws. Do not use wet, moldy, or otherwise contaminated or damaged seed.

Apply seed to all disturbed areas within 10 calendar days of soil disturbance.

"Furnish the kinds of seed and the amounts to be applied in terms of pure live seed as follows:

Quantity of Pure

Kind of Seed Live Seed (lbs/acre)

1. annual rye grass_ _ (20%)__ _____7.0__________

2. Idaho fescue_ __ _(25%)__ _____8.8__________

3. mountain brome_ (35%)__ ____12.2__________

4. bluebunch wheatgrass (15%)__ _____7.0__________

Total _____35 lbs/acre_ ____

Determine the pounds of seed to be furnished per acre by dividing the pounds of pure live seed required per acre by the product of the percent purity and percent germination.

Example: 5 lbs. pure live seed/acre = 6.5 lbs. commercial seed per acre

0.90 x 0.85 purity = 90% and germination = 85%

Seed is estimated using a standard average of 4 acres/mile (or 140 lbs/mile). This project has estimated about 5 acres to seed. This is an estimate only and Contractor is responsible for full coverage and any additional mileage.

Apply seed by the dry method. No fertilizer shall be used.

Acceptance Roadway obliteration will be evaluated based on visual inspection of the work for compliance with the contract. Work may be rejected at any time if it does not comply with the contract.

Measurement Measure the Roadway Obliteration items as listed in the schedule of items according to the Measurement and Payment Section.

Payment The accepted quantities will be paid at the contract price per unit measurement for the Road Obliteration pay items listed in the schedule of items. Payment will be full compensation for the work prescribed in this Section.
