87th Street Bridge over Springbrook Creek Replacement
City of Naperville, IL

Picture
ERA provided Phase I engineering services for the 87th Street Bridge (SN 19-00174) Replacement over the Springbrook Creek. The bridge will be replaced using federal funds. The existing bridge is a hydraulic restriction and overtops at storm events greater than the 10-yr storm. The structure is located adjacent to the DuPage County Forest Preserve and has mapped critical wetlands and will require no flood elevation increases for more than 3-inches for the 6-month, 1-year and 2-year storms. The phase I engineering consists of a Project Development Report (PDR), Bridge Condition Report (BCR), Hydraulic Report, Wetland Delineation and Environmental Assessments and public hearing.
