Aging wood infrastructure on the Great Lakes is on the rise. Explore the reasons why this is happening and what can be done about it.
A changing Wisconsin climate will bring challenges to ports, harbors and marinas. There could be changes in rainfall amounts and storm intensities as well as lake level changes, and wave and water-level erosion.
Many of the Great Lakes coastal communities, ports and harbors are protected from Great Lake storm, wave and ice damage by critical offshore and coastal structural protection. Maintenance of these structures has lagged behind and many structures are now in poor condition. Failure of these structures would be catastrophic for the valuable coastal communities they protect. The harbor structures were constructed with a variety of materials, each with its own failure mechanisms to repair or rehabilitate.
