A stabilization design of installing additional longer and reticulated rockbolts to stabilize the main arch, shorter rockbolts to stabilize individual arch rock blocks, selective vegetation removal and rock scaling of the cliff, treatment of the crack between the arch and alcove cliff, and instrumentation to monitor the installed stabilization has beencompleted by a geotechnical and structural engineering consultant for the NPS.
The USDA NRCS is preparing to issue a solicitation for work to restore and stabilize approximately 54 feet of stream bank on 1 site on Wades Creek in Greenbrier County, West Virginia. This is a repair to a site previously restored due to June 2016 flooding event. Wire Mesh Gabions will be installed to stabilize and protect the stream bank.
Catchment Fence: Steel cable and wire mesh catchment fence should be erected at the toe of the slope to prevent rockfall debris from reaching the transformer yard and switchgear building, and hence to protect existing structures. Secant Pile Retaining Wall: Construction of a secant pile retaining wall to stabilize the upper access road during the stripping and grading of the overburden on the slope downstream of the right abutment of the dam.
A portion of this project was completed in 2016 using redirective flow techniques to train the stream and stabilize the lateral movement of meander bends. The remaining elements of the project include a grade control structure at Hwy 183 and a retaining wall system to protect a vulnerable section the Southern Walnut Creek Trail.
Major work activities include applying rock mulch on the dam embankment to stabilize and protect against erosion, constructing an aggregate base course O&M road on the dam crest, grading the upstream toe O&M road and installing 4-strand barbed wire fencing. See the various Exhibits for the full scope of work. Description: Please upload your bid here.
Cover all landscape beds with 2 inches of crushed granite or sandstone rock mulch to stabilize slope soils, protect against erosion, and improve soil and plant health. Construct new cheek walls along the concrete path and steps to detain possible eroded soils and protect against draining into surface concrete ditches.
