(a) Grade. The finished grade of the soil shall slope away from the dwelling at a rate of at least one-half (1/2) inch per foot for a minimum distance of ten (10) feet, or to the lot line, whichever is less.
(b) Erosion Control Procedures.
(1) Performance Standards - General.
Perimeter erosion control measures shall be placed within twenty-four (24) hours after beginning of excavation. Erosion control measures shall be placed along downslope areas and along sideslope 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. The best management practices as defined in the Wisconsin Administrative Code or alternative measures that provide equivalent protection to these practices may be utilized to satisfy the requirements of this Section. When the disturbed area is stabilized, the erosion control measures may be removed.
(2) Stabilization by Seeding and Mulching.
Slopes greater than or equal to twelve percent (12%), with a downslope length of ten (10) feet or more, are not considered stabilized with seeding and mulching unless used in conjunction with a tackifier, netting, or matting. Asphalt emulsion may not be used as a tackifier.
(3) Tracking.
Sediment tracked by construction equipment from a site onto a public or private paved road or sidewalk shall be minimized by providing a non-tracking access roadway. The access roadway shall be installed as approved on the plot plan, prior to framing above the first floor decking. The sediment cleanup provisions of Subsection (b)(4) are unaffected by the presence or absence of an access roadway. [Note: It is not the intent of Subsection (b)(3) to require a gravel access roadway where natural conditions, such as sandy soils or solidly frozen soil, already provide non-tracking access.]
(4) Sediment Cleanup.
Off-site sediment deposition occurring as a result of a storm event shall be cleaned up by the end of the next work day following the occurrence. All other off-site sediment deposition occurring as a result of construction activities shall be cleaned up at the end of the work day.
(5) Public Sewer Inlet Protection.
Downslope, on-site public sewer inlets shall be protected with erosion control procedures.
(6) Building Material Waste Disposal.
All building material waste shall be properly managed and disposed of to prevent pollutants and debris from being carried off the site by runoff.
(c) Best Management Practices. Appropriate best management practices, as specified in Chapter 3, Wisconsin Construction Site Best Management Practices Handbook, published by the Wisconsin Department of Natural Resources, may be selected, installed, maintained and remain in place until the site is stabilized to meet the performance standards specified Section 15-2-6.
(d) Maintenance of Control Procedures.
(1) General.
During the period of construction at a site, all erosion control procedures necessary to meet the performance standards of this Section shall be properly implemented, installed and maintained by the building permit applicant or subsequent landowner. If erosion occurs after building construction activities have ceased, some or all of the erosion control procedures shall be maintained until the site has been stabilized.
(2) Exceptions and Clarification.
The maintenance procedures and inspection sequences with Chapter 3, Wisconsin Construction Site Best Management Practices Handbook, are not adopted as a part of this Chaper.
(e) Dismantling of Erosion Control Procedures. Except for permanent erosion control systems, the owner shall be responsible for dismantling and removing erosion control procedures once the soil on the site is stabilized.
