Big meadow creek culvert replacement project
Working with the Idaho Department of Fish & Game, Quadrant completed a fish passage assessment at four existing county road culverts on Big Meadow Creek in the vicinity of Troy, ID. Following the completion of this assessment, Quadrant provided hydraulic analysis to design improvements to three of the four culverts to provide salmonid passage up to the 25-year runoff event. Two culverts were 15’-10”-span multi-plate pipe arches, and one culvert was a 16’-span multi-plate single radius span with concrete footings. Quadrant provided preliminary and final project design drawings, costs estimates, and bidding assistance for culvert procurement.
