Which Shoreline Approach Would Work for My Property?

This interactive decision tool is meant to give you, a lakeshore landowner, ideas for which green shoreline approach might work on your property. Since each site is unique, the results are not prescriptive, and you are encouraged to consult with a professional to develop an approach that will address your property concerns, improve the visual appeal of your property, and provide the greatest habitat benefit for native fish and wildlife.

Several different agencies have a role in regulating lakeshore activities, and most have websites and helpful staff trained to lead lakeside property owners through the process.
