V:\Stormwater\Erosion Control Permits\Erosion Control Permit Application Final 2016 with Ordinance.docx
Sec. 19.10. Erosion Control Plan Requirements.
(a) General Erosion Control Plan Requirements and Performance Standards. An erosion control plan shall describe how the permit holder and other
responsible parties will minimize soil erosion and the transport of sediment from land disturbing activities to waters of the state or other property. To
meet this requirement, the following performance standards shall apply:
1. All erosion control plans and associated BMPs shall comply with the planning, design, implementation and maintenance requirements of this
ordinance and the Technical Standards prepared by the Wisconsin Department of Natural Resources.
2. All erosion control plans shall by design, achieve to the maximum extent practicable, a runoff discharge of no more than five tons of sediment per
acre per year from sheet and rill erosion during land disturbing activities, as compared with no sediment or erosion controls, until the site is
stabilized.
3. Erosion and sediment control BMPs may be used alone or in combination to meet the above noted performance standard. The requirements of
this Sec. 19.10 are designed to meet this standard.
(b) Guiding Principles for Erosion Control. To satisfy the requirements of this section, an erosion control plan shall adhere to the following guiding
principles:
1. Propose grading that best fits the terrain of the site, avoiding steep slopes, wetlands, floodplains, environmental corridors and any applicable
regulatory setbacks from these areas,
2. Minimize, through project phasing and construction sequencing, the time the disturbed soil surface is exposed to erosive forces.
3. Minimize soil compaction, the loss of trees and other natural vegetation and the size of the disturbed area at any one time;
4. Locate erosion control BMPs upstream from where runoff leaves the site or enters waters of the state and outside of wetlands, floodplains,
primary or secondary environmental corridors or isolated natural areas.
5. Emphasize the use of BMPs that prevent soil detachment and transport over those aimed to reduce soil deposition (sedimentation) or repair
erosion damage.
(c) Specific Erosion Control Plan Requirements. The following applicable minimum requirements shall be addressed in erosion control plans. The DPW
may establish more stringent erosion and sediment control requirements than the minimums set forth in this section if the DPW determines that an
added level of protection is needed to protect an environmentally sensitive area or other property, or to address a change made during plan
implementation.
1. Access Drives and Tracking. Provide access drive(s) for construction vehicles that minimize tracking of soil off site using BMPs such as stone
tracking pads, tire washing or grates. Minimize runoff and sediment from adjacent areas from flowing down or eroding the access drive.
2. Diversion of Upslope Runoff. Divert excess runoff from upslope land, rooftops or other surfaces, if practicable, using BMPs such as earthen
diversion berms, and downspout extenders. Prevent erosion of the flow path and the outlet.
3. Inlet Protection. Protect inlets to storm drains, culverts and other stormwater conveyance systems from siltation until the site is stabilized.
4. Soil Stockpiles. Locate soil stockpiles away from channelized flow and no closer than 25 feet from roads, ditches, lakes, streams, ponds, wetlands
or environmental corridors, unless otherwise approved by the DPW. Control sediment from soil stockpiles. Any soil stockpile that remains
unworked for more than 30 days shall be stabilized.
5. Cut and Fill Slopes. Minimize the length and steepness of proposed cut and fill slopes and stabilize them as soon as practicable.
6. Channel Flow. During construction, trap sediment in channelized flow before discharge from the site using BMPS such as sediment traps and
sediment basins. Complete final grading and stabilize open channels in accordance with DPW standards as soon as practicable, but in no event later
than the first ground freeze or snow cover in the fall.
7. Outlet Protection. Protect outlets from erosion during site dewatering and stormwater conveyance, including velocity dissipation at pipe outfalls
or open channels entering or leaving a stormwater management facility.
8. Overland Flow. Trap sediment in overland flow before discharge from the site using BMPs such as silt fence and vegetative filter strips.
9. Site Dewatering. Treat pumped water to remove sediment prior to discharge from the site, using BMPs such as sediment basins and portable
sediment tanks.
10. Dust Control. Prevent excessive dust from leaving the construction site though construction phasing and timely stabilization or the use of BMPs
such as site watering and mulch especially with very dry or fine sandy soils.
11. Topsoil Application. Save existing topsoil and reapply a minimum of 4 inches to all disturbed areas for final stabilization, unless otherwise
approved by the DPW, such as for temporary seeding or stormwater infiltration BMPs. If adequate topsoil does not exist on the site to meet this
requirement, it shall be imported or a topsoil substitute such as compost may be used, upon approval by the DPW.
12. Waste Material. Recycle or properly dispose all waste and unused building materials in a timely manner. Control runoff from waste materials
until they are removed or reused.
13. Sediment Cleanup. By the end of each workday, clean up all on-site and off-site sediment deposits or tracked soil that originated from the
permitted site. Flushing shall not be allowed unless runoff is treated before discharge from the site.
14. Final Site Stabilization. All previous cropland areas where land disturbing activities will not be occurring under the proposed grading plans shall
be stabilized within 30 days of permit issuance. Stabilize all other disturbed areas within 7 days of final grading and topsoil application. Large sites
shall be treated in stages as final grading is completed in each stage. Any soil erosion that occurs after final grading or the application of stabilization
measures must be repaired and the stabilization work redone.
15. Temporary Site Stabilization. Any disturbed site or portion thereof that remains inactive for greater than 7 days shall be stabilized with
temporary stabilization measures such as soil treatment, temporary seeding or mulching. For purposes of this subsection, “inactive” means that no
site grading, landscaping or utility work is occurring on the site or a portion of the site and that precipitation events are not limiting these activities.
Frozen soils do not exclude the site from this requirement.
16. Removal of Practices. Remove all temporary BMPs such as silt fences, ditch checks and sediment traps as soon as all disturbed areas have been
stabilized.
17. Site Drainage. Site drainage plans shall comply with the provisions of Sec. 19.11(d) 6. below.
18. Stormwater BMP Data. When a Stormwater Permit involves the maintenance of an existing stormwater BMP, including the removal of
accumulated sediment, the DPW may require additional support data such as before/after surveys, design and construction details, and oversight by
a professional engineer licensed in Wisconsin.
(d) Final Erosion Control Plan Contents. The following shall be the minimum requirements for items to be included in a final erosion and sediment
control plan:
1. Sites Less than One Acre of Total Land Disturbance.
