The City 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 Fond du Lac. The City Council 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, and 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.
A. 
Construction site erosion control purpose. 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 Fond du Lac.
B. 
Post-construction stormwater management 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 exceedance 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.
(4) 
Minimize the amount of pollutants discharged from the separate storm sewer to protect the waters of the state.
C. 
Post-construction stormwater management intent. It is the intent of the City Council 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 City Council 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 City Council, it is the intent of this chapter that the approved plan be used to identify post-construction management measures acceptable for the community.
D. 
Illicit discharge and connection purpose. The purpose of this chapter is to provide for the health, safety, and general welfare of the citizens of the City of Fond du Lac through the regulation of non-stormwater discharges to the MS4 to the maximum extent practicable as required by federal and state law. This chapter establishes methods for controlling the introduction of pollutants into the MS4 in order to comply with requirements of the WPDES permit process. The objectives of this chapter are as follows:
(1) 
To regulate the contribution of pollutants to the MS4 by stormwater discharges by any user.
(2) 
To prohibit illicit connections and discharges to the MS4.
(3) 
To establish legal authority to carry out all inspection, surveillance, monitoring, and enforcement procedures necessary to ensure compliance with this chapter.
E. 
Monitor and approve drainage plans submitted under § 325-4.1, Drainage plans.

A. 
A City Engineer-approved drainage plan and application shall be required for construction of any building with an area of 650 square feet or greater and for any grading or landscaping that will change the elevations of a lot, except for the addition of fill to lot depressions to maintain elevations within interior of a lot. A drainage plan submitted by the builder for the first-time construction of a single-family or two-family home may be prepared by a person other than a licensed professional, provided that the plan includes stamped certification of existing conditions at the time of plan preparation by a registered engineer, land surveyor or architect as described in Chs. A-E 1 to 13, Wis. Adm. Code, and required by the Department of Safety and Professional Services. No deviation from any drainage plan shall be permitted unless approved, in writing, by the City Engineer. No building permit shall be issued if the erection of the building and the proposed grades shall unreasonably obstruct the natural flow of water from the surface of adjoining property or obstruct the flow of any existing ravine, ditch, drain or stormwater sewer draining neighboring property, unless suitable provision is made for such flow by means of an adequate ditch, swale or pipe. If the City Engineer determines that surface water from adjoining property presently draining across the area to be developed will be diverted, the ditch, swale or pipe shall necessarily be a joint lot-line facility, and no property which has in the past been draining across vacant lands shall be held exempt from the development of a joint drainage facility. Any such drainage facility shall be shown on the plans and shall be constructed so as to provide continuous drainage at all times.
B.

The deposit shall be returned to the builder or property owner upon the final approved inspection of the lot drainage and public right-of-way infrastructure. If, during final inspection, the City Engineer directs corrective work and said corrective work is not completed, part or all of the deposit may be forfeited to the City of Fond du Lac for use in completing the corrective work. The amount of the deposit shall be set by resolution of the City Council.

The notice of appeal must be received by or filed with the Department of Public Works within three days from the date of the notice of violation. Hearing on the appeal before the appropriate authority or his/her designee shall take place within 30 days from the date of receipt of the notice of appeal.
