No legal liability on the part of the Government for any payment may arise for performance under this contract beyond the amount that has been authorized through the issuance of written task orders.

III. SCOPE OF SERVICES

Documentation: The contractor will provide a brief write-up documenting task outcomes and other information useful to this project and send a copy to the COR. Provide digital photos within the write-up and as external .jpg files (appropriately labeled) on a disc. The photos should be taken before, during and after the work from the same locations to document the process. A minimum of one location from each task listed is required for each project site.

General Information: Work is to begin on a Tuesday to allow travel during the work week by NPS personnel to the park.

Project closeout is to occur Monday afternoon through Friday morning. Weekend work is not permitted. All work shall be performed in accordance with IV. Quality Standards.

Existing Site Conditions: Expect conditions typical to that of Badlands National Park or silty clay (A-2-4(0)) or fat clay (A-7-6) during the spring season. In some cases hard soil can be expected and shall be anticipated by the contractor.

Task 1. Removing Rip-Rap, Importing Gravel, and Placing Pond Liner (Site A- Headwall 11 and 12)

a. The contractor will remove the rip-rap at each headwall and along the north edge of the drainage ponds.

Expect to move the material an average distance of 1 mile to area by lagoons south of maintenance yard.

Expect to remove approximately 20 cubic yards of materials at each headwall (40 cubic yards total) and up to 40 cubic yards along drainage ponds.

b. After removing rip-rap the contractor will import and install a gravel or roadbase material, material will be approved by COR after samples are submitted. (Expect to import ~135 cubic yards of material at Headwall 11and Headwall 12, total of 270 cubic yards) For final surface elevation see grading sheets for Cliffshelf.

c. Then place an impermeable fabric (pond liner) on top of road base and anchored at the edges by wrapping the liner under base material during base placement.

Task 2. Regrading (Sites A, and B)

a. Site A- 175 feet x 50 feet ~9,000 square feet. Contractor will utilize topsoil and subsoil materials in the existing “levee’s” or holding ponds. This material will be spread throughout the disturbed area. The final grade should provide for a consistent low angle drainage through, approximately, the center of the disturbed area matching the final grade of pond liner elevation, see grading sheets for Cliffshelf . This will direct water to the headwall near the road. Final grading will be approved by the COR. Also grade ditch line from north of Headwall 12 south past Headwall 11, approximately 900 feet in length.

b. Site B - Conata Culvert. There are 2 distinct regrading areas along the Conata road.

1. 25 feet x 75 feet, ~2,000 square feet. This culvert area is near the park loop road. The area near the inlet of the culvert is at a lower elevation than the outlet. Import topsoil material to fill pond area and regrade the area such that positive drainage to the inlet of the culvert is achieved.

2. 100 feet x 50 feet, ~5,000 square feet. This is a channel that is currently running close to a badland butte feature. The contractor will regrade and rechannellize the are to move the channel closer to the road.

c. Site C - Cliffshell Buttress Repair. This task also includes slope repair at Cliffshelf Buttress, Site prep, hand work to prepare surface, 125x30 feet~3750 square feet.

Task 3. Soil Scarifying (Site A)

a. Following regrading work the contractor is to scarify the soil using mechanical equipment or hand tools, to a depth of 4-6 inches. This will help to loosen the existing surface layer of soil and aid in long term vegetation establishment. Scarified soil, not receiving additional topsoil shall be smoothed by raking prior to seeding. If done with equipment scarifying will be done in a minimum of 2 passes with equipment and ripping teeth on equipment will be a maximum spacing of 8 inches apart.

Task 4. Planting

a. Area A will be strategically planted with potted shrubs (rabbitbrush, Ericameria nauseosa). Pots will be a combination of deep pot 40’s and 1-gallon sizes. Maximum planting will be 4oo plants.

b. Plants will be installed and watered upon installation per industry standards.

Task 5. Seeding (site A 14,000 square feet, Site B 7,000 square feet)

a. Hand seeding -broadcast (hand) seed evenly over disturbed area and rake seed into soil such that seed is at an average depth of ¼ inch.

b. A native seed mix will be provided by the government and will be applied evenly over the disturbed areas at a rate of 15 to 20 lbs. per acre.

Task 6. Installation of Fabric and Wattles (TRM, ECB, ECW) (Site A and B)

a. Turf Reinforcement Fabric (TRM) will be placed in the primary flow line at site A. The length of TRM will be 457 linear feet and width will be 8 ft.

b. Erosion Control Blanket (ECB) will be installed at site A at all disturbed areas. Disturbed area, not covered in TRM, is estimated at 12,200 square feet. Disturbed ground at site B will be covered with ECB. This area is estimated at 7,000 square feet. Install 125x30 feet~3750 square feet of ECB and 100 lin ft ECW. Install Erosion Control Wattles (ECW) per COR at both Site A and B.

c. All erosion control producs procured by the contractor shall be 100% biodegradable. Photodegradable netting is not acceptable.

Task 7. Traffic Control

a. This will include the use of flaggers and pilot cars for traffic control. Furnish, maintain, and relocate traffic control devices and services for control and protection of public traffic through the project in accordance with the Manual on Uniform Traffic Control Devices (MUTCD). Submit a traffic control plan for review and approval prior to beginning of work.

Task 8. Documentation

a. During on-site installation provide daily updates with photos of work accomplished to COR and PM via email. Provide documentation of daily labor utilized on the project, weather conditions (including air temperature and wind conditions), condition of seedbed (compaction, dry, wet, smooth, uniform, loose, large clods, rocks etc.), weed infestation including species present and estimated % ground coverage, seeding method, seeding rate, and seed mix utilized. Include a written summary and photo documentation of work in final report.
