Project Details

Schemmer was contracted to provide design services for new roadway, storm sewers and a bridge crossing the Big Papillion Creek for a one-mile stretch between West Maple Road and Fort Street. The use of federal funding and floodplain issues required an environmental action plan and close coordination with various agencies.

The project included an environmental assessment to determine air and noise impacts, wetland delineation and mitigation, and investigation of impacts on Tranquility Park and the Knolls Golf Course. Extensive hydraulic floodplain modeling was performed to mitigate potential flood issues. Schemmer coordinated with multiple agencies on these assessments, including the Federal Highway Administration, U.S. Army Corps of Engineers, Nebraska Department of Transportation, Papio-Missouri River Natural Resources District and Papio Creek Coalition.

The preliminary roadway design included two horizontal alignments and three vertical alignment alternatives, and determination of mitigation measures. The bridge design included type, size and location drawings of the bridge alternatives. Schemmer also provided geotechnical testing, traffic engineering including data collection and analysis, right-of-way, drainage design and meetings with the public and key stakeholders.
