Unless otherwise provided for in this article, all land development activities subject to this article shall establish on-site management practices to control the peak flow rates of stormwater discharged from the site as described in this article. The amount of peak discharge control previously required for the site shall not be reduced as a result of the proposed development or land disturbance. Infiltration of stormwater runoff shall be in accordance with Wis. Admin. Code Ch. NR 151 and WDNR Technical and Guidance Standards.
(f) Stormwater discharge quality. Unless otherwise provided for in this article, all land development activities subject to this article shall establish on-site management practices to control the quality of stormwater discharged from the site. On-site management practices shall be used to meet the following minimum standards established for each development district:
(1) Stormwater management measures in the Urban Expansion District and Urban Reserve District shall be designed to remove, on an average annual basis, a minimum of 80 percent of the total suspended solids load from the proposed on-site development when compared to the proposed on-site development without stormwater management measures. The effectiveness of the stormwater management measures shall be evaluated using criteria provided by the Director.
(2) Stormwater management measures for developments in the Urban Service District smaller than five acres shall be designed to remove, on an average annual basis, a minimum total suspended solids load of 40 percent for redevelopment sites and a minimum of 80 percent for new development from the proposed on-site development when compared to the proposed on-site development without stormwater management measures. The effectiveness of the stormwater management measures shall be evaluated using criteria provided by the Director.
(3) The Director may require stormwater management measures in the Urban Service District for developments five acres or larger to be designed to remove, on an average annual basis, a minimum of 80 percent of the total suspended solids load from the proposed on-site development when compared to the proposed on-site development without stormwater management measures. The effectiveness of the stormwater management measures shall be evaluated using criteria provided by the Director.
(4) Discharge of urban stormwater pollutants to natural wetlands shall have pretreatment and vegetative buffers, unless otherwise exempted by the Director.
