§ 185-1 Authority.

A. 
This chapter is adopted by the Town Board under the authority granted by § 60.627, Wis. Stats. This chapter supersedes all provisions of a chapter previously enacted under § 60.62, Wis. Stats., that relate to stormwater management regulations. Except as otherwise specified in § 60.627, Wis. Stats., § 60.62, Wis. Stats., applies to this chapter and to any amendments to this chapter.
B. 
The provisions of this chapter are deemed not to limit any other lawful regulatory powers of the same governing body.
C. 
The Town Board hereby designates the Director of Public Works to administer and enforce the provisions of this chapter.
D. 
The requirements of this chapter do not preempt more stringent stormwater management requirements that may be imposed by any of the following:
(1) 
Wisconsin Department of Natural Resources administrative rules, permits or approvals, including those authorized under §§ 281.16 and 283.33, Wis. Stats.
(2) 
Targeted nonagricultural performance standards promulgated in rules by the Wisconsin Department of Natural Resources under § NR 151.004, Wis. Adm. Code.

§ 185-2 Findings of fact.

The Town Board finds that uncontrolled, post-construction runoff has a significant impact upon water resources and the health, safety and general welfare of the community and diminishes the public enjoyment and use of natural resources. Specifically, uncontrolled post-construction runoff can:
A. 
Degrade physical stream habitat by increasing stream bank erosion, increasing streambed scour, diminishing groundwater recharge, diminishing stream base flows and increasing stream temperature.
B. 
Diminish the capacity of lakes and streams to support fish, aquatic life, recreational and water supply uses by increasing pollutant loading of sediment, suspended solids, nutrients, heavy metals, bacteria, pathogens and other urban pollutants.
C. 
Alter wetland communities by changing wetland hydrology and by increasing pollutant loads.
D. 
Reduce the quality of groundwater by increasing pollutant loading.
E. 
Threaten public health, safety, property and general welfare by overtaxing storm sewers, drainageways, and other minor drainage facilities.
F. 
Threaten public health, safety, property and general welfare by increasing major flood peaks and volumes.
G. 
Undermine floodplain management efforts by increasing the incidence and levels of flooding.

§ 185-3 Purpose and intent.

A. 
Purpose. The general purpose of this chapter is to establish long-term post-construction runoff management requirements that will diminish the threats to public health, safety, welfare and the aquatic environment. Specific purposes are to:
(1) 
Further the maintenance of safe and healthful conditions.
(2) 
Prevent and control the adverse effects of stormwater; prevent and control soil erosion; prevent and control water pollution; 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.
(3) 
Control exceeding of the safe capacity of existing drainage facilities and receiving water bodies; prevent undue channel erosion; control increases in the scouring and transportation of particulate matter; and prevent conditions that endanger downstream property.
B. 
Intent. It is the intent of the Town Board that this chapter regulates post-construction stormwater discharges to waters of the state. This chapter may be applied on a site-by-site basis. The Town Board recognizes, however, that the preferred method of achieving the stormwater performance standards set forth in this chapter is through the preparation and implementation of comprehensive, systems-level stormwater management plans that cover hydrologic units, such as watersheds, on a municipal and regional scale. Such plans may prescribe regional stormwater devices, practices or systems, any of which may be designed to treat runoff from more than one site prior to discharge to waters of the state. Where such plans are in conformance with the performance standards developed under § 281.16, Wis. Stats., for regional stormwater management measures and have been approved by the Town Board, it is the intent of this chapter that the approved plan be used to identify post-construction management measures acceptable for the community.

§ 185-4 Applicability and jurisdiction.

A. 
Applicability.
(1) 
Where not otherwise limited by law, this chapter applies after final stabilization to a site of land-disturbing construction activity that results in one or more acres of land-disturbing construction activities.
(2) 
A site that meets any of the criteria in this subsection is exempt from the requirements of this chapter:
(a) 
A redevelopment post-construction site with no increase in exposed parking lots or roads.
(b) 
A post-construction site with less than 10% connected imperviousness based on complete development of the post-construction site, provided the cumulative area of all parking lots and rooftops is less than one acre.
(c)
