A. 
The City Council of the City of Monona finds that construction site erosion and uncontrolled stormwater runoff from land-disturbing and land development activities have significant adverse impacts upon regional water resources and the health, safety, property and general welfare of the community and diminish the public enjoyment and use of natural resources. Specifically, soil erosion and stormwater runoff can:
(1) 
Carry sediment, nutrients, pathogens, organic matter, heavy metals, toxins and other pollutants to regional lakes, streams and wetlands;
(2) 
Diminish the capacity of water resources to support recreational and water supply uses and a natural diversity of plant and animal life;
(3) 
Clog existing drainage systems, increasing maintenance problems and costs;
(4) 
Cause bank and channel erosion;
(5) 
Increase downstream flooding;
(6) 
Reduce groundwater recharge, which may diminish stream base flows and lower water levels in regional lakes, ponds and wetlands;
(7) 
Contaminate drinking water supplies;
(8) 
Increase risk of property damage and personal injury; and
(9) 
Cause damage to agricultural fields and crops.
B. 
The City Council of the City of Monona also finds that effective sediment and stormwater management depends on proper planning, design and timely installation of conservation and management practices and their continued maintenance.
A. 
The purpose of this chapter is to set forth the minimum requirements for construction site erosion control and stormwater management that will diminish threats to public health, safety, public and private property and natural resources of the City of Monona.

(3) 
Promote infiltration and groundwater recharge;
(4) 
Protect functional values of natural watercourses and wetlands;
(5) 
Provide a set of performance standards that are consistent with the standards set forth by Dane County;
(6) 
Achieve an eighty-percent reduction in sediment load rates to Dane County waters compared to no controls for all parcels where new development occurs, a forty-percent reduction in sediment load rates compared to no controls for all redeveloped parcels and street reconstructions, and a twenty-percent reduction in sediment load rates compared to no controls for existing developments;
(7) 
Ensure no increase in the rate of surface water drainage from sites during or after construction; and
(8) 
Protect public and private property from damage resulting from runoff or erosion.

When dual HSG are specified, the drained condition shall be assumed.
(2) 
Oil and grease control. For all stormwater plans for commercial or industrial developments and all other uses where the potential for pollution by oil or grease, or both, exists, the first 0.5 inches of runoff will be treated using the best oil and grease removal technology available. This requirement may be waived by the plan reviewer only when the applicant can demonstrate that installation of such practices is not necessary.
(3) 
Runoff rate control - hydrologic calculations. All runoff calculations shall be according to the methodology described in the Natural Resources Conservation Service's Technical Release 55, "Urban Hydrology for Small Watersheds" (commonly known as TR-55), or other methodology approved by the Director. The maximum runoff curve number (RCN) used in such calculations shall be those shown in Table 1. The TR-55-specified curve numbers for other land uses shall be used. Heavily disturbed sites will be lowered one permeability class for hydrologic calculations. Lightly disturbed areas require no modification. Where practices have been implemented to restore soil structure to predeveloped conditions, no permeability class modification is required.
(4) 
Runoff rate control - design standards. All stormwater facilities shall be designed, installed and maintained to effectively accomplish the following:
(a) 
Redevelopment.
[Amended 6-19-2017 by Ord. No. 6-17-688]
[1] 
Maintain preredevelopment peak runoff rates for the two-year, twenty-four-hour storm event (2.84 inches over 24 hours' duration using the NRCS MSE4 storm distribution).
[2] 
Maintain preredevelopment peak runoff rates for the ten-year, twenty-four-hour storm event (4.09 inches over 24 hours' duration using the NRCS MSE4 storm distribution).
[3] 
Safely pass the one-hundred-year, twenty-four-hour storm event (6.66 inches over 24 hours' duration using the NRCS MSE4 storm distribution) without inundating buildings or causing damage to structures.
(b) 
New development.
[Amended 6-19-2017 by Ord. No. 6-17-688]
[1] 
Maintain predevelopment peak runoff rates for the one-year, twenty-four-hour storm event (2.49 inches over 24 hours' duration using the NRCS MSE4 storm distribution).
[2] 
Maintain predevelopment peak runoff rates for the two-year, twenty-four-hour storm event (2.84 inches over 24 hours' duration using the NRCS MSE4 storm distribution).
[3] 
Maintain predevelopment peak runoff rates for the ten-year, twenty-four-hour storm event (4.09 inches over 24 hours' duration using the NRCS MSE4 storm distribution).
[4] 
Maintain predevelopment peak runoff rates for the one-hundred-year, twenty-four-hour storm event (6.66 inches over 24 hours' duration using the NRCS MSE4 storm distribution).
(5) 
Outlets. Discharges from new construction sites must have a stable outlet capable of carrying designed flow as required in Subsection B(4), at a nonerosive velocity. Outlet design must consider flow capacity and flow duration. This requirement applies to both the site outlet and the ultimate outlet to stormwater conveyance or water body.
(6) 
Infiltration.
(a) 
Redevelopment. All downspouts, driveways and other impervious areas shall be directed to pervious surfaces, where feasible, or unless the applicant can demonstrate that the practice is likely to result in groundwater contamination.
(b) 
New development.
[1] 
For both residential and nonresidential developments, design practices to infiltrate sufficient runoff volume so that post-development infiltration volume shall be at least 90% of the predevelopment infiltration volume, based upon average annual rainfall.
[2] 
The maximum predevelopment runoff curve number (RCN) used in such calculations shall be those as specified in § 216-13B(1)(b), Table 1.
[3] 
If when designing appropriate infiltration systems more than 2% of the site is required to be used as effective infiltration area, the applicant may alternately design infiltration systems and pervious surfaces to meet or exceed the annual predevelopment recharge rate. The annual predevelopment recharge rate shall be determined from the Wisconsin Geological and Natural History Survey's 2009 report, Groundwater Recharge in Dane County, Estimated by a GIS-Based Water-Balanced Model, or subsequent updates to this report, or by a site-specific analysis using other appropriate techniques. If this alternative design approach is taken, at least 2% of the site must be used for infiltration.
[4] 
Pretreatment. Before infiltrating runoff, pretreatment shall be required for parking lot runoff and for runoff from new road construction in commercial, industrial and institutional areas that will enter an infiltration system. The pretreatment shall conform to the design standards in § 216-16 and be designed to protect the infiltration system from clogging prior to scheduled maintenance and to protect groundwater quality.
[5] 
Prohibitions. Notwithstanding Subsection B(6)(b)[1] through [3], infiltration systems may not be installed in any of the following areas:
[a] 
Areas associated with Tier 1 industrial facilities identified in § NR 216.21(2)(a), Wis. Adm. Code, including storage, loading, rooftop and parking.
[b] 
Storage and loading areas of Tier 2 industrial facilities identified in § NR 216.21(2)(b), Wis. Adm. Code.
[c] 
Fueling and vehicle maintenance areas.
[d] 
Areas within 1,000 feet upgradient or within 100 feet downgradient of direct conduits to groundwater.
[e] 
Separation distances. Infiltration practices shall be located so that the characteristics of the soil and the separation distance between the bottom of the infiltration system and the elevation of seasonal high groundwater or the top of bedrock are in accordance with Table below:

[h] 
Areas where contaminants of concern, as defined in § NR 720.03(2), Wis. Adm. Code, are present in the soil through which infiltration will occur.
[6] 
Alternate use of runoff. Where alternate uses of runoff are employed, such as for toilet flushing, laundry or irrigation, such alternate use shall be given equal credit toward the infiltration volume required by this section.
[7] 
Minimizing groundwater pollution. According to Ch. NR 151, Wis. Adm. Code, infiltration systems designed in accordance with this section shall, to the extent technically and economically feasible, minimize the level of pollutants infiltrating to groundwater and shall maintain compliance with the preventive action limit at a point of standards application in accordance with Ch. NR 140, Wis. Adm. Code. However, if site-specific information indicates that compliance with the preventive action limit is not reasonably achievable, the infiltration system may not be installed or shall be modified to prevent infiltration to the maximum extent practicable.
C. 
Stormwater management goals. The following standards shall be met whenever possible, and proposed design, suggested location and implementation of practices to meet these goals shall be included in plans:
(1) 
For existing development, design practices to retain soil particles greater than 40 microns on the site (twenty-percent reduction) resulting from a one-year twenty-four-hour storm event, according to approved procedures and assuming no sediment resuspension.
(2) 
For street reconstruction, design practices to retain soil particles greater than 20 microns on the site (forty-percent reduction) resulting from a one-year, twenty-four-hour storm event, according to approved procedures and assuming no sediment resuspension.
Off-site stormwater management is allowed, provided that all of the following conditions for the off-site facility are met:
