Coastal hazards like erosion and flooding along Wisconsin’s Great Lakes coasts can threaten homes, businesses and infrastructure. Below is a list of available resources and tools that can help:
- Understand coastal hazards
- Assess your vulnerability
- Review options for addressing coastal hazards
- Implement Actions
This list is also available as a printable PDF document
While these tools can be helpful to gauge coastal hazard risk and develop a plan, major or immediate concerns should seek assistance from an engineer, geologist, or other qualified professional. Wisconsin Sea Grant is providing a list of Great Lakes coastal engineering and/or bluff stability consulting firms as a resource for property owners looking for professionals who can provide expertise and services. This list is not meant to be an endorsement of any firm, nor is it all-inclusive.
Understanding Coastal Processes
When dealing with coastal hazards like erosion and flooding, it can be helpful to understand how the forces of nature like water levels and waves can combine to threaten your property.
Living on the Coast
Booklet describing natural coastal processes and overall strategies to manage risk to coastal properties. It is a go-to resource for getting a broad understanding of the issues facing a property.
Flood and erosion hazard mapping combined can help begin to understand the risk a particular property may face from coastal hazards
Wisconsin Shoreline Inventory and Oblique Photo Viewer
View historic photos of the coast, assessments of bluff and shoreline conditions, and measurements of historic bluff and shoreline recession in a web-based, interactive map of Wisconsin coastal data.
FEMA Flood Map Service Center
A Search-By-Address tool to quickly see if a property is in a FEMA mapped floodplain, which indicates it is at high flood risk. Properties not in a FEMA mapped floodplain should still assume they are at a moderate to low flood risk.
Reviewing Your Options
Many possible options exist to address coastal hazard issues. The appropriate actions for a particular property are often situational and site specific.
