NR 115.05(1)(e)1. 1. `Appli cation.' Impervious surface standards shall apply to the construction, reconstruction, expansion, replacement or relocation of any impervious surface that is or will be located within 300 feet of the ordinary high water mark of any navigable waterway on any of the following:

NR 115.05(1)(e)3.c. c. For lots or parcels described under subd. 1 that exceed the impervious surface standard under subds. 2. and 2m., but do not exceed the maximum impervious surface standard under subd. 3. a. or b., the county shall issue a permit that requires a mitigation plan approved by the county and implemented by the property owner by the date specified in the permit. The mitigation plan shall include enforceable obligations of the property owner to establish or maintain measures that the county deter mines adequate to offset the i mpacts of the impervious surface on water quality, near-shore aquatic habitat, upland wildlife habitat and natural scenic beaut y.
