Document Description
The proposed project consists of modifications to the Sly Creek Dam and spillway to address safety issues associated with the probable maximum flood flow event that would be conveyed through Sly Creek reservoir and the spillway. The crest of the dam would be raised 10 ft. Spillway modifications would involve replacing the existing radial gate with a pneumatic bottom-hinged spillway gate raising the walls of the spillway channel ~1-6ft. Portions of Barton Hill/Lewis Ridge Road would be raised to match the grade of the dam crest and maintaint existing drainage patterns. Following construction, the borrow site would be reshaped and vegetated as necessary to stabilize cuts or benches and restore drainage patterns. No change in authorized reservoir storage or maximum water surface level is proposed.
