NR 151.125(1)(j)
(j) Notwithstanding pars.
(a) to
(i), the greatest protective area width shall apply where rivers, streams, lakes, and wetlands are contiguous.
NR 151.125 Note
Note: A stream or lake is not eligible for a lower protective area width even if contiguous to a less susceptible wetland.
NR 151.125(2)
(2) Applicability. This section applies to post-construction sites located within a protective area, except those areas exempted pursuant to sub.
(4).
NR 151.125(3)
(3) Requirements. The following requirements shall be met:
NR 151.125(3)(a)
(a) Impervious surfaces shall be kept out of the protective area entirely or to the maximum extent practicable. If there is no practical alternative to locating an impervious surface in the protective area, the storm water management plan shall contain a written, site-specific explanation.
NR 151.125(3)(b)
(b) Where land disturbing construction activity occurs within a protective area, adequate sod or self-sustaining vegetative cover of 70 percent or greater shall be established and maintained where no impervious surface is present. The adequate sod or self-sustaining vegetative cover shall be sufficient to provide for bank stability, maintenance of fish habitat, and filtering of pollutants from upslope overland flow areas under sheet flow conditions. Non-vegetative materials, such as rock riprap, may be employed on the bank as necessary to prevent erosion such as on steep slopes or where high velocity flows occur.
NR 151.125 Note
Note: It is recommended that seeding of non-invasive vegetative cover be used in the protective areas. Some invasive plants are listed in ch.
NR 40. Vegetation that is flood and drought tolerant and can provide long-term bank stability because of an extensive root system is preferable. Vegetative cover may be measured using the line transect method described in the University of Wisconsin extension publication number A3533, titled “Estimating Residue Using the Line Transect Method".
NR 151.125(3)(c)
(c) Best management practices such as filter strips, swales, or wet detention ponds, that are designed to control pollutants from non-point sources, may be located in the protective area.
NR 151.125 Note
Note: Other laws, such as ch.
30, Stats., and chs.
NR 103,
115,
116, and
117 and their associated review and approval processes may apply in the protective area.
NR 151.125(4)
(4) Exemptions. This section does not apply to any of the following:
NR 151.125(4)(c)
(c) Structures that cross or access surface waters such as boat landings, bridges, and culverts.
NR 151.125(4)(e)
(e) Areas of post-construction sites from which the runoff does not enter the surface water, including wetlands, without first being treated by a BMP to meet the requirements of ss.
NR 151.122 to
151.123, except to the extent that vegetative ground cover is necessary to maintain bank stability.
NR 151.125 Note
Note: A vegetated protective area to filter runoff pollutants from post-construction sites described in par. (e) is not necessary since the runoff at that location is treated prior to entering the surface water. Other practices necessary to meet the requirements of this section, such as a swale or pond, will need to be designed and implemented to reduce runoff pollutants prior to runoff entering a surface water of the state. The requirements of ch.
NR 103 still apply and should be considered before runoff is diverted to or from a wetland.

This subchapter establishes performance standards, as authorized by s.
281.16 (2) (a), Stats., for transportation facilities that cause or may cause runoff pollution. These performance standards are intended to limit runoff pollution in order to achieve water quality standards. Design guidance and the process for developing technical standards to implement this subchapter are set forth in subch.
V.
NR 151.20(2)
(2) Transportation facilities that are directed and supervised by the department of transportation and that are regulated by an administrative rule administered by the department of transportation, where the department determines in writing that the rule meets or exceeds the performance standards of this subchapter and is implemented in accordance with the administrative rule provisions, shall be deemed to meet the requirements of the portions of this subchapter determined by the department.
NR 151.20(3)
(3) In s.
NR 151.23, soil loss is calculated using the appropriate rainfall or runoff factor, also referred to as the R factor, or an equivalent design storm using a type II distribution, with consideration given to the geographic location of the site and the period of disturbance.
NR 151.20 Note
Note: The universal soil loss equation and its successors, revised universal soil loss equation and revised universal soil loss equation 2, utilize an R factor which has been developed to estimate soil erosion, averaged over extended time periods. The R factor can be modified to estimate monthly and single-storm erosion.
