SITE
The entire area included in the legal description of the land on which the land disturbing or land development activity is proposed in the permit application.
All control measures required to comply with this chapter shall meet the design criteria, standards and specifications for the control measures based on accepted design criteria, standards and specifications identified by the Building Inspector.
All sedimentation basins and other control measures necessary to meet the requirements of this chapter shall be maintained by the applicant or subsequent landowner during the period of land disturbance and land development of the site in a satisfactory manner to ensure adequate performance and to prevent nuisance conditions.
(a) 
Applicability. This section applies to the following sites of land development or land disturbing activities:
(1) 
Those requiring a subdivision plat approval or the construction of houses or commercial, industrial or institutional buildings on lots of approved certified surveys.
(2) 
Those requiring a certified survey approval or the construction of houses or commercial, industrial or institutional buildings on lots of approved certified surveys.
(3) 
Those involving grading, removal of protective ground cover or vegetation, excavation, land filling or other land disturbing activity affecting a surface area of 4,000 square feet or more.
(4) 
Those involving excavation or filling or a combination of excavation and filling affecting 400 cubic yards or more of dirt, sand or other excavation or fill material.
(5) 
Those involving street, highway, road or bridge construction, enlargement, relocation or reconstruction.
(6) 
Those involving the laying, repairing, replacing or enlarging of an underground pipe or facility for a distance of 300 feet or more.
NOTE: The above applicability criteria are specifically stated in 1983 Wisconsin Act 416 for inclusion in this chapter. Utility companies responsible for energy repair work should enter into a "memorandum of agreement" with the Building Inspector clearly stating their responsibilities if their activities may be included under any of the above applicability criteria.
(b) 
Erosion and other pollutant control requirements. The following requirements shall be met on all sites described in Subsection (a).
(1) 
Site dewatering. Water pumped from the site shall be treated by temporary sedimentation basins, grit chambers, sand filters, up-slope chambers, hydrocyclones, swirl concentrators, or other appropriate controls designed and used to remove particles of 100 microns or greater for the highest dewatering pumping rate. If the water is demonstrated to have no particles greater than 100 microns during dewatering operations, then no control is needed before discharge, except as determined by the Building Inspector. Water may not be discharged in a manner that causes erosion of the site or receiving channels.
NOTE: There are several ways to meet this particle size performance objective, depending on the pumping rate. As an example, if the pumping rate is very low (1 gal/min), then an inclined or vertical enlargement pipe (about 8 inches in diameter for 1 gal/min) several feet long would be an adequate control device to restrict the discharge of 100 micron, and larger, particles. As the pumping rate increases, then the "device" must be enlarged. At a moderate (100 gal/min) pumping rate, a vertical section of corrugated steel pipe, or concrete pipe section, or other small "tank" (about 4-1/2 feet across for a 100 gal/min pumping rate) several feet tall would be adequate. With these pipe sections or small tanks, inlet baffles would be needed to minimize turbulence. With very large pumping rates (10,000 gal/min), sediment basins (about 35 feet in diameter for a pumping rate of 10,000 gal/min) at least three feet in depth with a simple (but adequately sized) pipe outlet would be needed. More sophisticated control devices (such as swirl concentrators or hydro-cyclones) could be specially fabricated that would generally be smaller than the simple sedimentation devices described above, but they would not be required.
(2) 
Waste and material disposal. All waste and unused building materials (including garbage, debris, cleaning wastes, wastewater, toxic materials, or hazardous materials) shall be properly disposed and not allowed to be carried by runoff into a receiving channel or storm sewer system.
(3) 
Tracking. Each site shall have graveled roads, access drives and parking areas of sufficient width and length to prevent sediment from being tracked onto public or private roadways.
(4) 
Drain inlet protection. All storm drain inlets shall be protected with a straw bale, filter fabric, or equivalent barrier meeting accepted design criteria, standards and specifications.
(5) 
Site erosion control. The following criteria apply only to land development or land disturbing activities that result in runoff leaving the site:
a. 
Channelized runoff from adjacent areas passing through the site shall be diverted around disturbed areas, if practical. Otherwise, the channel shall be protected as described below in Subsection (5)(c)(3). Sheet flow runoff from adjacent areas greater than 10,000 square feet in area shall also be diverted around disturbed areas unless shown to have resultant runoff velocities of less than 0.5 feet/sec across the disturbed area for the set of one-year design storms. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels.
NOTE: Soil and Conservation Service guidelines for allowable velocities in different types of channels should be followed.
b. 
All activities on the site shall be conducted in a logical sequence to minimize the area of bare soil exposed at any one time.
c. 
Runoff from the entire disturbed area on the site shall be controlled by meeting either of the following:
1. 
All disturbed ground left inactive for seven or more days shall be stabilized by seeding or sodding (only available prior to September 15th) or by mulching or covering, or other equivalent control measure.
2. 
For sites with more than 10 acres disturbed at one time, or if a channel originates in the disturbed area, one or more sedimentation basins shall be constructed. Each sedimentation basin shall have a surface area of at least 1% of the area draining to the basin and at least three feet of depth and constructed in accordance with accepted design specifications. Sediment shall be removed to maintain a depth of three feet. The basin shall be designed to trap sediment greater than 15 microns in size, based on the set of one-year design storms having durations from 0.5 to 24 hours. The basin discharge rate shall also be sufficiently low as to not cause erosion along the discharge channel or the receiving water.
3. 
For sites with less than 10 acres disturbed at one time, filter fences, straw bales, or equivalent control measures shall be placed along all side slope and down slope sides of the site. If a channel or area of concentrated runoff passes through the site, filter fences shall be placed along the channel edges to reduce sediment reaching the channel.
d. 
Any soil or dirt storage piles containing more than 10 cubic yards of material should not be located with a down slope drainage length of less than 25 feet to a roadway or drainage channel. If remaining for more than seven days, they shall be stabilized by mulching, vegetative cover, tarps or other means. Erosion from piles which will be in existence for less than seven days shall be controlled by placing straw bales or filter fence barriers around the pile. In-street utility repair or construction soil or dirt storage piles located closer than 25 feet of a roadway or drainage channel must be covered with tarps or suitable alternative control if exposed for more than seven days, and the storm drain inlets must be protected with straw bales or other appropriate filtering barriers.
(a) 
Permit application. No landowner or land user may commence a land disturbance or land development activity subject to this chapter without receiving prior approval of a control plan for the site and a permit from the Building Inspector. At least one landowner or land user controlling or using the site and desiring to undertake a land disturbing or land developing activity subject to this chapter shall submit an application for a permit and a control plan and pay an application fee to the Building Inspector. By submitting an application, the applicant is authorizing the Building Inspector to enter the site to obtain information required for a review of the control plan.
