The scope of work involves furnishing all labor, materials, services and equipment required to perform: naturalization/restoration of approximately 2,600 linear feet of Genetta Ditch which is currently contained within a concrete-lined channel. The completed restoration will serve to attenuate non-point source pollution while restoring natural stream elements and biological function which were lost when the stream was channelized. The portion of Genetta Stream to be naturalized (restored) begins where the stream exits a box culvert under Interstate 65, south of Fairview Avenue, and continues to just upstream of the CSX railway bridge. The concrete-lined channel parallels Interstate 65, and lies within the Alabama Department of Transportation (ALDOT) right of way (ROW). The project will remove portions of the existing concrete-lined channel and provide reinforcement to the remaining concrete channel sections adjacent to the interstate though installation of a proposed soil nail wall system. Engineered design of the soil nail wall system will be the responsibility of the successful bidder. A new channel alignment and associated floodplain will be constructed. The channel will include a system of riffles, pools, cross-vane structures, and substrate. The project will re-purpose much of the old concrete channel material which will be crushed for use as channel substrate and gabion fill. The scope of work includes completion of all grading and stream restoration activities, including but not limited to general site grading, construction of in stream structures, temporary and permanent seeding, and erosion control.
