Wisconsin Administrative Code NR 115 sets uniform impervious surface coverage limits for shoreland properties statewide. Counties must adopt these standards, typically capping coverage at 15 percent, with mitigation allowing up to 30 percent in certain circumstances.
Wis. Admin. Code NR 115.05(1)(e) limits impervious surfaces in shoreland zones to 15 percent of the lot area within 300 feet of the ordinary high water mark, or 30 percent with approved mitigation. 2015 Wisconsin Act 55 prohibited counties from imposing stricter limits. Impervious surfaces include roofs, driveways, sidewalks, and similar features. Mitigation typically involves restored vegetation, rain gardens, or stormwater management practices. Non-shoreland lot coverage rules remain local zoning matters under Wis. Stat. § 62.23.
Exceeding impervious limits without mitigation may require removal of structures, payment of forfeitures, and restoration. Enforcement is through county zoning administrators.
