Full Breakdown

Wis. Stat. section 59.692 requires counties to adopt shoreland zoning meeting NR 115 minimum standards within 1,000 feet of a lake or pond and 300 feet of a river or stream. Standards include 75-foot setbacks from the ordinary high water mark, vegetative buffer requirements, impervious surface limits of 15 percent, and mitigation when expanding nonconforming structures. The Public Trust Doctrine (Wis. Const. art. IX, sec. 1) protects navigable waters and Great Lakes shorelines below the ordinary high water mark for public use. 2015 Act 55 limits how much stricter counties may go beyond NR 115 minimums.

Violations & Penalties

Violations may result in injunctions, restoration orders, daily forfeitures, removal of unpermitted structures, and replanting of vegetative buffers under Wis. Stat. 59.69(11) and 30.294.

Frequently Asked Questions

What is the shoreland setback in Wisconsin?

Principal structures must sit at least 75 feet from the ordinary high water mark of any navigable lake, pond, river, or stream, with limited reductions allowed.

Can my county require stricter shoreland rules?

Counties must meet NR 115 minimums but 2015 Act 55 generally caps stricter local standards. Existing stricter ordinances are preempted unless authorized by statute.

Who owns the Great Lakes shoreline?

Lands below the ordinary high water mark are held in trust for public use under the Public Trust Doctrine. Private upland owners have qualified riparian rights.
