Project highlights: 

• Services included coordination with the Norfolk Southern Railroad, Metra, and Illinois Commerce Commission to obtain consensus of the proposed at-grade pedestrian crossing and installation of pedestrian railroad gates. New pedestrian signal heads and push buttons were installed for the new crossings on Wolf Road and 108th Avenue intersections.

• We performed the wetland delineation for the project and determined Marley Creek to be a Waters of the U.S. and emergent wetland. Due to the location of the proposed improvements within the Marley Creek regulatory floodway/floodplain and the desire to minimize wetland and floodway/floodplain impacts we navigated the design and permitting to achieve minimal impacts and obtain all appropriate permits.

• The improvements included the extension of an existing box culvert at the southwest corner of 167th Street and Wolf Road to accommodate the new path as well as a new railroad crossing pad and pedestrian railroad signals where the path crosses the Metra southwest service line.

• The west end of the Wolf Road culvert was connected to the north end of the 167th culvert by curved structure making hydraulic modeling of culverts a key element of the project.
• An existing steep embankment was located just east of Wolf Road. Upon analysis of various options, a segmented block retaining wall was incorporated in the design to minimize right-of-way impacts and make it possible to retrofit the ADA compliant path.
• The project was locally funded and was processed through IDOT-Local roads so that the Village was eligible for federal funding for Phase II and Phase III Engineering and Construction.
