Patrick performed design of a levee and associated improvements to reduce the impacts of flooding from the Little Calumet River into an adjacent residential neighborhood. Patrick's scope included a detailed watershed study to confirm watershed limits and identify up to three conceptual solutions to manage overland flow on the land side of the levee. The team performed a detailed river survey to obtain adequate bank cross sections and bathymetric survey to perform detailed hydraulic design of the river modifications and to adequately model the river for the dam modifications, rock riffle, and levee design. Geotechnical field investigation was performed to determine foundation conditions for the levee and potential borrow sources for levee construction. Preliminary design included the levee, detention basins, pump stations and storm sewer improvements to handle storm water flows upland of the proposed levee. Phase 1 included removal of the top of an existing sheet pile wall dam across Deep River, installation of rock riffles with fish and canoe passages, a boat launch constructed of articulated concrete block mat, public parking areas, and a bike path with pedestrian bridge connecting the residential area to a recreation building on the other side of the river. Phase 1 was completed in 2021.
