This project resulted from the mitigation requirement of a Nationwide Permit 21 authorization for proposed impacts to jurisdictional waters due to surface mining. This project included baseline investigations of 4,831 feet of stream to be impacted as well as the design of a compensatory mitigation plan (CMP) for the proposed impacts. The CMP included the restoration/enhancement of 2,237 feet of Salyers Branch and the creation of 2,334 feet of high gradient ephemeral channels. A detailed monitoring plan was also included as part of the CMP. In May 2008, Miller Bros. Coal selected Summit Engineering to perform oversight inspection and postconstruction monitoring for the mitigation project. During construction, Summit Engineering personnel provided on-site technical assistance with regards to reshaping the channel, bankfull benches, and bank slopes, including stakeout and as-built surveying. Personnel directed the placement cross-vanes, boulders clusters, root wads, riffle areas, and step-pool sequences. Initial establishment and enhancements of the riparian buffer was also observed and technical support offered to the contractor as necessary.
Project Scope: Project permitting included project management, design review, technical assistance, and engineering certification. Project construction includes onsite technical assistance, progress reports, as-built surveys, and monitoring reports.
Project Size: Project area is a 488-acre mining site located in Floyd County, Kentucky proposing 4,831 feet of stream impacts and 4,571 feet of stream creation, restoration, and enhancement following mining.
