Coffey Creek Environmental Mitigation

Work performed under this contract will involve construction of a Hydraulic Cut-Off Barrier to limit migration of contaminants into Coffey Creek.  The barrier will be constructed below grade of Composite Bentonite Aggregate (CBA) and will be roughly 400 feet long, 12 feet tall, and 1 foot wide.  The project site is located within the secure area of Charlotte-Douglas International Airport and will require that all security measures be followed throughout the duration of the project.
