About this file
This is a technical design document and construction drawings package for a streambank stabilization project funded through the Emergency Watershed Protection (EWP) Act by the Natural Resources Conservation Service (NRCS), a division of the U.S. Department of Agriculture.
The project involves stabilization of Elkhorn Creek at two sites in McDowell County, West Virginia. Site 1 utilizes grouted rock riprap streambank stabilization approximately 75 feet in length, with estimated quantities including 500 square yards of geotextile, 79 tons of blanket drain rock, 25 linear feet of drain pipe, 10 linear feet of perforated drain pipe, 5 each of drain pipe caps and tees, 179 tons of riprap, and 36 cubic yards of grout riprap, with 30 square yards of foundation preparation on shallow bedrock. Site 2 employs a 7.5-foot-high gabion wall approximately 93 feet in length with estimated quantities of 155 square yards of gabion geotextile, 160 cubic yards of gabions, 186 tons of rock riprap foundation preparation, and 248 square yards of geotextile foundation preparation. Both sites include channel bottom reconfiguration to restore original stream widths and provide positive drainage. Construction notes specify adherence to West Virginia Department of Highways requirements, pollution control measures per Construction Specification 5, waste disposal at approved off-site locations, and traffic control procedures. The project is classified as Job Approval Class V and includes detailed technical specifications for riprap placement, drain pipe installation, gabion wall construction with lacing requirements, foundation preparation on shallow bedrock with rebar drilling patterns, and final grading and seeding operations.

CONSTRUCTION NOTES
1. Call 811 to locate utilities prior to mobilization and excavation.
2. Access roads shall be restored to pre-construction condition or better.
3. All fences removed and/or damaged as a result of the contractor's operations shall be restored to a condition equal to or better than they existed before the start of work.
4. Soil compacted as a result of construction operations shall be loosened for a depth of 6-inches below the compacted soil layer and re-graded to blend with existing ground.
5. Provide sub-channel as shown on Typical Channel Bottom Configuration drawing.
6. While working in the stream all efforts will be made to reduce downstream impacts including keeping the excavator tracks elevated above flowing water. A diversion berm shall be established at the top of each stream access point to minimize surface water from flowing toward the stream.
7. Required pollution control measures shall be installed as needed in accordance with Construction Specification 5, Pollution Control.
8. Site access shall be off the main road and shall be in accordance with all West Virginia Department of Highways rules and guidelines. The contractor shall provide signage and flagmen for traffic control as required. See Construction Specification 9, Traffic Control.
9. Excess material from the excavation & obstruction removal shall be wasted off-site in accordance with all local, state, & federal regulations and as approved by the NRCS representative in the field. Floodplains will not be allowed as waste areas under any circumstances. Waste areas shall be seeded according to Construction Specification 6, Seeding, Sprigging and Mulching.
10. The contractor shall provide approved fill as required to complete the work.
11. Trash, tires, & woody debris within the work limits shall be disposed of off-site in an approved landfill. The contractor shall be responsible for the landfill tipping fees.
12. All pipes encountered in the embankment shall be extended through the rock riprap and/or gabions with the same pipe material or better to the face of the slope or baskets.
13. Pipes 12" diameter and larger shall be encased in a minimum of 6" of concrete when passing through rock riprap and/or gabions. Concrete shall have a minimum compressive strength of 2500 psi.
14. The contractor shall maintain the cleanliness of public and private roads impacted by hauling operations during the duration of the work.
15. Starting location of baskets will be marked in the field.
16. Reshape/transition stream banks at the upstream and downstream ends of stabilization measures as directed by NRCS representative.

1. Drill holes for Rebar shall be 1 3/8" diameter. The use of epoxy or non-shrink grout is not required.
The rebar shall be driven by hammer to the required depth without bending.
2. Care shall be taken by the contractor to prevent damage to the rebar during gabion filling operations.
3. Different gabion bottom layer configurations will require additional rebar by repeating the pattern shown. Quantities on sheet 2 based on bottom width x length.
NOTE: Final pattern and spacing to be directed by NRCS representative in the field. Na tu ra l R es ou rc es Co ns er va tio n Se rv ice
