  • "Erosion control measures shall be placed along down slope areas and along side slope areas as required to prevent or reduce erosion where erosion during construction will result in a loss of soil to waters of the state, public sewer inlets or off-site." (Reference: Section Comm 21.125(1)(a) of the Wisconsin Administrative Code).
  • "Slopes greater than or equal to 12% with a down slope length of 10 feet or more, are not considered stabilized with seeding and mulching unless used in conjunction with a tackifier, netting, or matting." (Reference: Section Comm 21.125(b) of the Wisconsin Administrative Code).
