[HISTORY: Adopted by the Common Council of the City of St. Francis 10-19-2004 by Ord. No. 1172 (§ 14.13 of the 1981 Code). Amendments noted where applicable.]
This chapter is adopted under the authority granted by § 62.234, Wis. Stats. This chapter supersedes all provisions of an ordinance previously enacted under § 62.23, Wis. Stats., that relate to construction site erosion control. Except as otherwise specified in § 62.234, Wis. Stats., § 62.23, Wis. Stats., applies to this chapter and to any amendments to this chapter.
The provisions of this chapter are deemed not to limit any other lawful regulatory powers of the same Common Council.
The Common Council hereby designates the Building Inspector to administer and enforce the provisions of this chapter.
The requirements of this chapter do not preempt more stringent erosion and sediment control requirements that may be imposed by any of the following:
Wisconsin Department of Natural Resources administrative rules, permits or approvals, including those authorized under §§ 281.16 and 283.33, Wis. Stats.
Targeted nonagricultural performance standards promulgated in rules by the Wisconsin Department of Natural Resources under § NR 151.004, Wis. Adm. Code.
The Common Council finds that runoff from land disturbing construction activity carries a significant amount of sediment and other pollutants to the waters of the state in the City of St. Francis.
It is the purpose of this chapter to further the maintenance of safe and healthful conditions; prevent and control water pollution; prevent and control soil erosion; protect spawning grounds, fish and aquatic life; control building sites, placement of structures and land uses; preserve ground cover and scenic beauty; and promote sound economic growth, by minimizing the amount of sediment and other pollutants carried by runoff or discharged from land disturbing construction activity to waters of the state in the City of St. Francis.
This chapter applies to the following land disturbing construction activities except as provided under Subsection B:
A construction site which has five or more acres of land disturbing construction activity.
A construction site which has one or more acres of land disturbing construction activity after March 10, 2003.
Those requiring subdivision plat approval.
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.
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.
Those involving street, highway, road or bridge construction, enlargement, or relocation, excluding construction under the direct supervision of the Wisconsin Department of Transportation.
Those involving the laying, repairing, replacing or enlarging of an underground pipe or facility for a distance of 300 feet or more.
This chapter does not apply to the following:
Land disturbing construction activity that includes the construction of a building and is otherwise regulated by the Wisconsin Department of Commerce under § Comm 21.125, Wis. Adm. Code.

For this chapter, average annual basis is calculated using the appropriate annual rainfall or runoff factor, also referred to as the "R factor," or an equivalent design storm using a Type II distribution, with consideration given to the geographic location of the site and the period of disturbance.
Responsible party. The responsible party shall implement an erosion and sediment control plan, developed in accordance with § 212-9, that incorporates the requirements of this section.
Plan. A written plan shall be developed in accordance with § 212-9 and implemented for each construction site.
Erosion and other pollutant control requirements. The plan required under Subsection B shall include the following:
BMP's that, by design, achieve to the maximum extent practicable a reduction of 80% of the sediment load carried in runoff, on an average annual basis, as compared with no sediment or erosion controls until the construction site has undergone final stabilization. No person shall be required to exceed an eighty-percent sediment reduction to meet the requirements of this subsection. Erosion and sediment control BMP's may be used alone or in combination to meet the requirements of this subsection. Credit toward meeting the sediment reduction shall be given for limiting the duration or area, or both, of land disturbing construction activity or other appropriate mechanism.
Notwithstanding this Subsection B(1), if BMP's cannot be designed and implemented to reduce the sediment load by 80% on an average annual basis, the plan shall include a written and site-specific explanation as to why the eighty-percent reduction goal is not attainable and the sediment load shall be reduced to the maximum extent practicable.
Where appropriate, the plan shall include sediment controls to do all of the following to the maximum extent practicable:
The use, storage and disposal of chemicals, cement and other compounds and materials used on the construction site shall be managed during the construction period to prevent their entrance into waters of the state. However, projects that require the placement of these materials in waters of the state, such as constructing bridge footings or BMP installations, are not prohibited by this subsection.
Location. The BMP's used to comply with this section shall be located prior to runoff entering waters of the state.
Alternate requirements. The Building Inspector may establish stormwater management requirements more stringent than those set forth in this section if the Building Inspector determines that an added level of protection is needed for sensitive resources.
Permit required. No responsible party may commence a land disturbing construction activity subject to this chapter without receiving prior approval of an erosion and sediment control plan for the site and a permit from the Building Inspector.
Permit application and fees. At least one responsible party desiring to undertake a land disturbing construction activity subject to this chapter shall submit an application for a permit and an erosion and sediment control plan that meets the requirements of § 212-9 and shall pay an application fee as provided by the current fee schedule on file with the City Clerk to the Building Inspector. By submitting an application, the applicant is authorizing the Building Inspector to enter the site to obtain information required for the review of the erosion and sediment control plan.
