State of Wisconsin LAKESHORE EROSION CONTROL— RIPRAPNEGETATED ARMORING <br /> Department of Natural Resources General Permit Application Checklist <br /> d nr.wi.gov (11/2016) <br /> Eligibility criteria: <br /> Projects that do not meet all criteria are not eligible for this general permit. If your project <br /> does not qualify for this general permit, you may apply for an individual permit. <br /> Riprap or vegetated armoring may not exceed 200 linear feet of shoreline. <br /> The project site is a moderate or high energy site; or a low energy site where the bank-edge <br /> recession described in s. NR 328.08 (3) is equal to or greater than 0.5 feet per year and the <br /> applicant can show a biological erosion control structure was previously placed according to the <br /> standards in s. NR 328.04 (3) and (4). <br /> Note: NR 328.08 (3) requires that the time between separate measurements shall equal or exceed 3 <br /> months during the open-water season. <br /> Note:The applicant will satisfy the'equal to or greater than 0.5 feet per year" requirement by <br /> demonstrating that the bank-edge recession is equal to or greater than 1.5 inches per 3 months during <br /> the open-water season. <br /> Riprap shall be clean fieldstone or quarry stone 6 to 24 inches in diameter. <br /> The toe of the riprap may not extend more than 8 feet waterward of the ordinary high water <br /> mark. <br /> The final riprap slope may not exceed (be steeper than) 2 feet horizontal to one foot vertical. <br /> Riprap may not be placed at an elevation higher than the ordinary high water mark plus the <br /> storm-wave height as calculated in s. NR 328.08 (1). For waters subject to subch. II, riprap <br /> may not be placed at an elevation higher than the ordinary high water mark plus 1.5 times the <br /> storm-wave height calculated in s.NR 328.08. <br /> Note:The listed waters in sub ch. II are typified by following conditions-impounded; 2500 acres and <br /> larger; extensive water level fluctuation; high shoreline recession rates; historic loss of shoreline <br /> vegetation. <br /> No fill material or soil may be placed in a wetland or below the ordinary high water mark of any <br /> navigable waterway. <br /> The riprap shall follow the natural contour of the shoreline. <br /> Filter cloth or clean-washed gravel shall be used as a filter layer under the riprap to extend the <br /> life of the structure, improve effectiveness and prevent soil erosion behind the riprap. <br /> mprap or other vegetated armoring along moderate energy sites shall be re-vegetated above <br /> the ordinary high water mark by using native shrub plantings, native live stakes or native jointed <br /> plantings. <br /> Note: Erosion control treatments may include a 10-foot shoreline segment where plant establishment is <br /> not required for the purpose of ingress/egress associated with the placement of a pier or access to the <br /> waterway, or associated with public park activities. <br /> The structure may be placed and maintained only by a riparian. <br /> The project will not result in removal of greater than 20% of the aerial coverage of natural bank <br /> vegetation, emergent vegetation or floating vegetation, not including the area covered by the <br /> footprint of the riprap, or any access corridors necessary for the placement of the riprap. <br /> Any grading, excavation and land disturbance shall be confined to the minimum area necessary <br /> for the construction and may not exceed 10,000 square feet. <br /> 3 <br />
