Project Description
The primary objectives of the project will be to stabilize channel banks; enhance the riparian zone through invasive species management and native re-vegetation; and create floodplain basins to filter flood flows and storm water from adjoining properties. Sevenmile Creek in the project area has increased runoff due to urban development, causing the stream to incise where possible and to widen. In-channel habitat in the project area is limited to localized irregularities in the limestone bed and exposed rock plates. Sevenmile Creek has been listed on the 303(d) list due to impacts from storm water discharges and hydro-modification. In addition, it provides habitat for the federally-listed Nashville Crayfish (Orconectes shoupi). Re-grading and planting of unstable banks will reduce erosion and improve water quality. The restored riparian buffer will decrease stream temperatures and provide habitat for terrestrial animals. The floodplain basins will help improve water quality, decrease peak flows in Sevenmile Creek, and provide valuable floodplain habitat.
