Sheboygan, WI Environmental Rules: Erosion Control (2026)

Appendix D, the Construction Site Erosion Control Ordinance for Sheboygan, applies inside the city to a construction site with one or more acres of land disturbance, to any activity needing subdivision plat or certified survey map approval, to grading, excavation or land filling affecting four thousand square feet or more of surface, to excavation or fill of four hundred cubic yards or more, to street, highway, road or bridge work, and to underground pipe or facility work over three hundred feet or more. Section 2.1(c) also reaches a site of any size when the City Engineer judges that its runoff will exceed the safe capacity of existing drainage facilities or endanger property or public safety. Land disturbance that includes the construction of a building is excluded by Section 2.1(b)(1), as are agricultural and silviculture discharges, routine maintenance on sites under 5 acres, and state agency work.

The performance standard in Section 4.1 is a reduction of 80% of the sediment load carried in runoff, to the maximum extent practicable, with no one required to exceed 80%. Section 6.0 adds site rules: sediment that reaches a public or private road must be removed by street cleaning, not flushing, before the end of each workday; downstream storm drain inlets get a straw bale, filter fabric or equivalent barrier; disturbed ground left inactive for seven or more days must be stabilized, with seeding or sodding required from April 15th to September 15th; sites with ten or more acres disturbed at one time need sedimentation basins; and soil piles over ten cubic yards must stay at least twenty-five feet of downslope drainage length from a roadway or drainage channel.

The plan and permit steps sit in Sections 7.0 and 8.0. Sites of one or more acres file a full plan with a site map at one inch equals one hundred feet and five-foot contours; sites up to one acre file a plan statement with a simple map at building permit application. Public Works/Engineering reviews within forty-five days, and a permit runs one hundred eighty days or the life of the building permit, whichever is longer. Permit holders must notify the City within forty-eight hours of starting work and inspect controls within twenty-four hours after each rain of 0.5 inches or more. Section 7.0(d) points one- and two-family applicants to the fees in Section 26-38, which lists an erosion control permit and stormwater management administration fee for one- and two-family residential uses of 100.00; commercial, industrial and multi-family fees are set by Common Council resolution.
