FOREWORD An Environmental Class of Action Determination (ECAD) was prepared resulting in a Categorical Exclusion Group II classification approved by the Federal Highway Administration (FHWA) on August 14, 2003. Subsequently, the Dan Ryan Expressway reconstruction project received Design Approval on August 21, 2003. The Build Alternative Scenario #2 (ECAD Approved Alternate) met the Purpose and Need and was selected as the build alternate. As a result of community concerns the Dan Ryan Taskforce was convened in January 2004 to further engage the community in the planning of the Dan Ryan Expressway reconstruction project. The Taskforce represented over 20 communities surrounding the Dan Ryan Expressway. The charge of the Taskforce was to determine whether options to Scenario #2 (ECAD Approved Alternate) could be developed that would restore some or all of the ramps that were proposed to be removed with Scenario #2 (ECAD Approved Alternate). From this community outreach effort, the preferred course of action is Scenario #3 (Preferred Alternate). The following Environmental Assessment (EA) addresses the environmental issues areas for both Scenario #2 (ECAD Approved Alternate) and Scenario #3 (Preferred Alternate).
