Recommended Alignment

The goal of this task is to examine the existing alignment and the proposed Grayslake Bypass alignment from the McHenry County Line to Illinois 131 and determine the preferred alignment. Components of this task:

1. Collect and inventory information and data within the corridor
2. Prepare a base map using aerial photography and GIS data including property lines, utilities, roadway names, GIS data, and other pertinent base line information.
3. Review and analyze the existing conditions through the use of available GIS, aerials, mapping, and field visits. See data for mapping products.
