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.

What Do I Need to Know About Permitting My Project?

Planning to repair or replace your dock? Is your bulkhead failing? Do you want easier beach access? For shoreline property owners, knowing what permits are required, which design alternatives are right for your shoreline and dock, and who to call can seem confusing. 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.
