Green Bay Avenue, Chicago, Illinois

CDOT Green Bay Avenue

The project consisted of Phase II engineering services for the reconstruction of 2000 feet of Green Bay Avenue from 83rd Street to 86th Street, along with the construction of 300’ of new 84th Street roadway from Green Bay Avenue to Lake Shore Drive. A new storm sewer system was also constructed beneath 85th Street from Green Bay Avenue to Lake Shore Drive. The existing roadway system had failing pavement, old sidewalks located only on the west side of Green Bay, and inadequate sewers for drainage. The project included construction in the former US Steel site, to implement the new segment of 84th Street which would then provide additional access from Green Bay to Lake Shore Drive.

The work included construction of new pavement with separate permeable asphalt lanes for storm water infiltration, new sidewalk and curb & gutter designed at 25’to 50’ intervals to avoid damaging Green Bay’s existing landscaping and tree system, demolition of 1500 feet of retaining walls, partial regrading of the US Steel site, soil contamination analysis, easements, street lighting, and landscaping. GRAEF designed separate storm and sanitary sewer networks, including 2000’ of 42” and 48” sanitary sewer and 1700’ of large box storm culverts and elliptical storm sewers. Major utility analysis was required due to the two sewer systems, water main and the need to accommodate a large future development on the adjacent site between Green Bay Avenue and Lake Shore Drive. The sewer design included analyzation of multiple options to reduce private utility and water line conflicts while still providing proper conveyance. All sidewalk ramps were designed to meet ADA requirements and intersections included bump outs to reduce pedestrian street crossing distances. GRAEF coordinated with CDOT, the Chicago Department of Water Management sewer and water sections, the US Steel site developer, and other utilities.
