Our environmental services included stream reviews, fluvial geomorphologic assessment, and hydrography and hydraulic analysis for the J-vane design at the bridge. We also performed construction review for the select quarry rock material and oversight during rock J-vane placement. This instream rock vane is located immediately downstream of the City of Lebanon and subject to high-flow discharges resulting from an urban/impervious watershed. We worked with the contractor to direct and support the rock vane construction and in-channel scour hole placement.
