Pre-Construction
Tyger River is a mitigation bank located in the Southern Piedmont Level IV Ecoregion within the Tyger River Watershed (HUC 03050107). The project provides stream and wetland mitigation credits to compensate for unavoidable impacts to waters of the United States authorized under Sections 401 and 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act.Â
The project will restore, enhance, reestablish, and preserve 71,310 feet of streams, 12.318 acres of wetlands, and 502 acres of riparian and upland buffers within the 544-acrebank.Â

Project Goals
- Restore and enhance the hydrologic and hydraulic function of 42,751 linear feet of existing streams using geomorphic channel design approaches to stabilize stream beds and banks, improve stream channel geometry, and reconnect streams to the floodplain; install grade control and in-stream habitat structures to maintain riffle-pool and step pool bed forms; and remove two existing road crossings on Motely Branch and improve one existing road crossing on Cane Creek to allow unimpeded passage of aquatic life
- Reestablish 5,408 linear feet of new stream channels to reconnect tributaries to the Tyger River, Cane Creek, and Motley Branch
- Enhance 0.539 acre of existing wetlands and facilitate the re-establishment of wetlands by restoring natural hydrology, creating micro topography and depressions, and planting native hardwoods, shrubs, and herbaceous vegetation
- Preserve 12,144 linear feet of the Tyger River, 11,007 linear feet of stable tributaries, and 5.075 acres of functioning forested wetlands
- Preserve intact hardwood upland and riparian buffers and enhance buffers currently planted in a pine monoculture
- Permanently protect these aquatic resources and riparian and upland buffers in a 544-acre conservation easement.
