Anderson Creek Relocation
In order to expand its Anderson Creek Quarry to access additional rock reserves, a national mining company hired Resource to relocate Anderson Creek. . The project required obtaining permits from the U.S. Army Corps of Engineers (Corps) and the Virginia Department of Environmental Quality (DEQ) to relcation 300 feet of the creek closer to the project boundary. The project was reviewed and approved with conditions by the Environmental Protection Agency (EPA), U.S. Fish and Wildlife Service (FWS), Virginia Department of Conservation and Recreation (DCR), Virginia Department of Game and Inland Fisheries (DGIF) and the Virginia Department of Mining, Minerals, and Energy (DMME).
To complete the project Resource's work entailed:
- An extensive hydrologic study
- Survey cross sections of the existing creek and flood plain
- Reproduce those configurations in the relocated channel
- Inoculate the new channel with material from the existing creek
- Bioengineering techniques in stabilizing the new creek channel to the extent practicable
The Rosgen Method of stream channel morphology was used provide the design parameters for the relocated stream. Temporary and permanent stream stabilization techniques employed included but were not limited to: coir mesh, brush mattresses, woody plants, stream meanders, river rock and Gabions.
The project took 24 months to design and permit. It provided the quarry with approximately 50 more years of life.
The Resource environmental team has completed a 5 year environmental monitoring program that has demonstrated the effectiveness of the relocation design and construction.
