Section NR 343.05 - Erosion control plan requirements

Universal Citation: WI Admin Code ยง NR 343.05

Current through August 26, 2024

(1) SITE-SPECIFIC PLAN. Any person required to submit an application for a pond or artificial water body under this chapter shall develop a site specific erosion control plan in accordance with s. NR 216.46(1) to (4).

(2) SITE MAP REQUIREMENTS. Each pond or artificial water body site map shall include all of the following:

(a) Existing topography and drainage patterns, roads, waterways and floodplain boundaries.

(b) Location, description and elevation of a reference benchmark.

(c) Horizontal and vertical scale and north arrow.

(d) Approximate identification of the ordinary high water mark.

(e) Area between the project site and the water body to be left undisturbed.

(f) Boundaries of the construction site, including the area of land disturbing construction activity.

(g) Drainage patterns and approximate slopes anticipated after grading activities, including the existing and proposed slope of the bank and the water level of the existing waterway.

(h) Area of soil disturbance in square feet.

(i) Volume of earth to be added or removed in cubic yards.

(j) Location of any disposal area for dredged or excavated materials.

(k) Location of major structural and non-structural controls identified in the erosion control plan.

(L) Location of areas where stabilization practices will be employed.

(m) Areas that will be vegetated following land disturbing construction activities.

(n) Area and location of wetland acreage on the pond or artificial water body site and locations where stormwater is discharged to a surface water or wetland within one-quarter mile downstream of the pond or artificial water body site.

(o) Areas used for infiltration of post-construction stormwater runoff.

(p) An alphanumeric or equivalent coordinate system for the entire construction site.

Note: 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 (e), (i) and (j).

(3) EROSION AND SEDIMENT CONTROL BEST MANAGEMENT PRACTICES. The erosion control plan shall include a description of appropriate erosion and sediment control best management practices that will be installed and maintained at the pond or artificial water body site to prevent pollutants from reaching waters of the state. The erosion control plan shall clearly describe the appropriate erosion and sediment control best management practices for each major 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).

(4) EROSION AND SEDIMENT CONTROL TECHNICAL STANDARDS.

(a) 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.

Note: These standards can be found at the following website: http://dnr.wi.gov/topic/stormwater/standards/.

(b) 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.
