From 2011 to 2013, the U.S. Army Corps of Engineers (USACE) Great Lakes Navigation Team conducted a series of regional meetings to communicate the risks associated with aging federal coastal infrastructure including breakwaters, jetties, and piers across the Great Lakes basin.
These meetings were held in person with state and local officials to present harbor-specific condition assessments and discuss the risks posed by deferred maintenance. While designed for navigation, many of these structures also protect critical community infrastructure and are increasingly vulnerable due to age and deterioration.
