NR 117.03 Note Note: The water level in a glacial pothole lake may remain above the“ordinary high-water mark” several years after flooding, resulting in a“high-water mark” which is above the “ordinary high-water mark.” However, there would be no practical difference between the “high-water mark” of a glacial pothole lake and the “ordinary high-water mark” of a glacial pothole lake where the effects of such flooding are no longer evident.

NR 117.03(10) (10) “Special exception (conditional use)” means a use which is permitted by a zoning ordinance provided that certain conditions specified in the ordinance are met and that a permit is granted by the board of appeals or, where appropriate, the city or village planning agency or governing body.

NR 117.03(11) (11) “Village planning agency” means a village planning commission created under ss. 61.35 and 62.23 (1), Stats., or a committee of the village board which acts on matters pertaining to village planning.

NR 117.03(12) (12) “Wetland”, as defined in s. 23.32 (1), Stats., means an area where water is at, near or above the land surface long enough to be capable of supporting aquatic or hydrophytic vegetation and which has soils indicative of wet conditions.
