NR 341.05(2)(r)(r) Cross sections of pre- and post-construction contours, sufficient to show slope variability across the site with a minimum of one for every 50 feet of shoreline frontage. If the site is uniform, only one cross section is necessary.

NR 341.05(2)(s)(s) Where wetlands are present, a wetland delineation report.

NR 341.05 NoteNote: Many of the requirements for a grading project site map are identical to the construction site map requirements of s. NR 216.46. A site map prepared to meet the requirements of s. NR 216.46 will need to add the information requested in pars. (b) to (f), (j), (k), (o), (r) and (s).

NR 341.05(3)(a)(a) The erosion control plan shall include a description of appropriate erosion and sediment control best management practices that will be installed and maintained from the start of land disturbing construction activities until final stabilization of the grading site. The erosion control plan shall clearly describe the appropriate erosion and sediment control best management practices for each land disturbing construction activity and the timing during the period of land disturbing construction activity that the erosion and sediment control best management practices will be implemented. The erosion and sediment control best management practices shall be designed in accordance with s. NR 216.46 (6).

NR 341.05(3)(b)(b) Erosion control measures shall meet or exceed the technical standards for erosion control approved by the department under subch. V of ch. NR 151. Any area where topsoil is exposed during construction shall be immediately seeded and mulched or riprapped to stabilize disturbed areas and prevent soils from being eroded and washed into the waterway.

NR 341.05(3)(c)(c) Unless part of a permanent stormwater management system, all temporary erosion and sediment control practices shall be removed upon final site stabilization. Areas disturbed during removal shall be restored.

NR 341.06NR 341.06 Stormwater management plan requirements. Pollution caused by stormwater discharges from the grading site after construction is completed, including rooftops, parking lots, roadways and the maintenance of grassed areas, shall be addressed by a stormwater management plan. Any person required to submit an application for a grading permit under this chapter shall develop one of the following site specific stormwater management plans:

NR 341.06(1)(1) Sites greater than one acre of land disturbance. A stormwater management plan shall be developed in accordance with s. NR 216.47 prior to submitting an application for a grading permit to the department. The plan shall be implemented upon final stabilization of the grading site.

NR 341.06(2)(2) Sites less than one acre of land disturbance. A stormwater management plan shall, to the maximum extent practicable, direct runoff from impervious surfaces onto pervious surfaces. Examples may include directing downspouts onto lawns and away from pavement, driveways sloped onto lawns, and avoidance of piping or channelizing flow from impervious areas into waters of the state. The plan shall be implemented upon final stabilization of the grading site.

NR 341.07NR 341.07 Construction site inspections and maintenance. Any person required to submit an application for a grading permit under this chapter shall follow the reporting and monitoring requirements in s. NR 216.48 (4).

NR 341.08(1)(a)(a) General permits shall be processed according to the procedures in ch. NR 300.

NR 341.08 NoteNote: Where there is overlapping jurisdiction between ch. NR 216 and this chapter for sites with land disturbance of more than one acre, the department will develop consolidated procedures so that only one submittal will be required.

NR 341.08(1)(b)(b) If the department determines that a grading application submitted under this section has the potential to impact an endangered or threatened species in accordance with s. 29.604, Stats., the application shall be deemed incomplete until the applicant submits documentation to demonstrate one of the following:

NR 341.08(1)(c)(c) If the applicant modifies their grading project plans to meet the requirements of par. (b), the modified plans shall be submitted before the department can consider the application complete or issue a general permit.

NR 341.08(2)(2) Applicable activities. A grading project that meets the requirements in sub. (3) shall be eligible for general permit coverage under ss. 30.19 (3r) (b) and 30.206, Stats.

NR 341.08(3)(a)(a) Performance standards. The grading project meets the stormwater performance standards of ss. NR 151.11 and 151.12 for stormwater discharges from land disturbing construction activities for non-transportation projects and ss. NR 151.23 and 151.24 for transportation projects.

NR 341.08 NoteNote: The department maintains a list of technical standards that it has determined adequate and effective for designing best management practices to control erosion and sediment runoff.
