HEI was selected by the Illinois Department of Transportation, District 1 to perform a Phase I study the US Rte. 30 corridor from IL Rte. 47 to IL Rte. 31. The study area is located in the Village of Montgomery and the United City of Yorkville in Kane & Kendall Counties. It extends approximately 5 miles. The corridor consists of a mixture of residential, commercial, industrial, and agricultural uses and is bisected by Blackberry Creek. The study area is expected to see significant development and traffic growth. Improvements are needed to address safety, roadway capacity and pedestrian/bicycle needs. A vital component of the study was an extensive public involvement program that provided for meaningful opportunities for all interested stakeholders and the public at large to participate in defining the transportation issues and solutions for this corridor. HEI developed a project website and led the public outreach program which included Community Advisory Group (CAG) meetings, local agency meetings, newsletters, public meetings, and a public hearing. A range of alternatives were developed that met the corridor’s needs and through an iterative process comparing the benefits and impacts of each alternative. Public input was gathered to help narrow the list and a preferred alternative was identified. The preferred alternative was then refined and presented at a Public Hearing. A major component of the overall study was noise analysis. Noise barriers were deemed found to be feasible and reasonable at nine locations and favored in eight locations. HEI performed noise analysis and noise barrier public outreach.
