[HISTORY: Adopted by the Village Board of Trustees of the Village of Slinger as Ch. 15 of the former Municipal Code. Amendments noted where applicable.]
GENERAL REFERENCES
Stormwater management and erosion control — See Ch. 526.
The Village of Slinger finds that the management of stormwater and other surface water discharges within and beyond the Village of Slinger is a matter that affects the health, safety and welfare of the Village, its citizens and businesses and others in the surrounding area. Failure to effectively manage stormwater affects the sanitary sewer utility operations of the Village by, among other things, increasing infiltration to the sanitary sewer. In addition, surface water runoff causes erosion of lands, damages to businesses and residences, sedimentation, and other environmental damage in the Village of Slinger. In order to protect the health, safety and welfare of the public, the Village of Slinger is exercising its authority to establish a Stormwater Utility for stormwater management services. The Village is acting under the authority of §§ 61.34, 61.36, 62.04, 62.11, 62.16, 62.175, 62.18, 66.0621, 66.0627, 66.0809, 66.0811 and 66.0821, Wis. Stats.
There is hereby established a Stormwater Utility in the Village of Slinger. The operation of the stormwater utility shall be managed by the Director of Public Works, under the supervision and control of the Village Board.
The Village, acting through the stormwater utility, may acquire, construct, lease, own, operate, maintain, extend, expand, replace, clean, dredge, repair, conduct, manage and finance such facilities, operations and activities, as are deemed by the Village to be proper and reasonably necessary for a system of storm and surface water management. These facilities may include, without limitation due to enumeration, surface and underground drainage facilities, watercourses, retaining walls, ponds, streets, roads, ditches and such other facilities as will support a stormwater management system.
In their interpretation and application, the provisions of this chapter shall be interpreted liberally to secure the ends sought hereby and shall not be deemed a limitation or repeal of any other power granted by the Wisconsin Statutes.
The following terms, whenever they occur in this chapter, are defined as follows:

It is the statistical average horizontal impervious area ("impervious area") of all single-family residential parcels within the Village of Slinger on the date of the establishment of the Stormwater Utility. The impervious area includes, but is not limited to, all areas covered by structures, roof extensions, patios, porches, driveways, sidewalks, pavement, gravel, compacted clay, and loading docks.

NONRESIDENTIAL PROPERTY

RESIDENTIAL PROPERTY
A lot or parcel of land developed exclusively for residential purposes and specifically shown as residential zoning on the Village's Official Zoning Map.

A. 
By this chapter, the Village Board is establishing the customer classification and basis for computation of charge for stormwater services for each lot and parcel within the Village of Slinger. The actual charges to be imposed pursuant to these rate classifications and any future changes in those rates shall be made by resolution. A schedule of current rates, following approval by the Village Board shall be maintained and on file in the Clerk's office.[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
B. 
The rate classifications used to distribute the costs of the stormwater program among utility customers shall be based on the equivalent runoff unit (ERU). The number of ERUs assigned to each parcel shall be assessed based upon the impervious area or dwelling units as reasonably determined by the Director of Public Works, except for undeveloped properties and public right-of-way, which shall be exempt from the utility charge.
A. 
Customer classes. For the purposes of imposing the stormwater charges, all lots and parcels within the Village are classified into the following customer classes:
(1) 
Residential. Lots or parcels within the Village specifically zoned as residential in accordance with the zoning set forth by ordinance shall be assigned one ERU for every dwelling unit on each lot or parcel.
(2) 
Nonresidential. Lots or parcels within the Village not specifically zoned as described above shall be considered as nonresidential by this chapter. Said lots or parcels shall be assigned one ERU for every 4,300 square feet of impervious surface area.
B. 
Parcel classification. The Director of Public Works shall assign a customer classification to each lot and parcel within the Village of Slinger.
C. 
ERU. The ERU is established to be 4,300 square feet.
A. 
Residential. The charges imposed for single family properties shall be one ERU for every dwelling unit on each lot or parcel, i.e.:
Residential parcel charge = (Number of dwelling units) x ERU fee
B. 
Nonresidential. The charges imposed for nonresidential properties shall be one ERU for every 4,300 square feet of impervious surface area on each lot or parcel, i.e.:
Nonresidential parcel charge = (impervious surface area/4,300 square feet) x ERU fee
C. 
Right-of-way. Public highway, road and rail right-of-way shall be exempt from the stormwater utility fee.
D. 
Impervious area measurement. The Director of Public Works shall be responsible for determining the impervious area of nonresidential parcels based on the reasonably available information, including, but not limited to, data supplied by the Village Assessor, Director of Public Works, aerial photography, property owner, tenant, or developer or site plan approved by the Village Plan Commission. The Director of Public Works may require additional information as necessary to make the determination. The number of ERUs on any lot or parcel shall be updated by the Director of Public Works based on any additions to the impervious area as approved through the building permit process.
The Village Board shall, by resolution, set or adjust the ERU fee to reflect the costs of the stormwater management program.[2]

The Village shall separately account for the Stormwater Utility finances. The Director of Public Works shall prepare an annual budget, which is to include all operation and maintenance costs, costs of borrowing and other costs related to the operation of the utility. The budget is subject to approval by the Village Board. Any excess of revenues over expenditures in a year will be deposited in a stormwater maintenance fund, which will be used to defer the costs of capital improvements or to retire debt.
A. 
Bills. Stormwater utility charges shall be billed to the owner/occupant of each property as set forth by resolution. The property owner/occupant shall be responsible for payment of the Stormwater Utility charge.
B. 
Late payment. Failure to pay the charges when due will be subject to a late payment charge of 1% per month that will be added to bills not paid within 20 days of issuance.
C. 
Unpaid charges. In addition to any other method of collection allowed by law, unpaid charges may be assessed as a lien against the property pursuant to § 66.0821, Wis. Stats.
A. 
Adjustments. A customer may be eligible to have the number of ERUs assigned to its property adjusted under the conditions described below:[1]
(1) 
Undeveloped property. Undeveloped properties may be eligible to reduce the number of ERUs assigned to the property.
(2) 
Nonresidential property. Nonresidential customers who believe the number of ERUs allocated to their property to be incorrect may submit an adjustment request to the Director of Public Works. The allocated ERUs may be adjusted if the owner can provide information showing the square footage calculation for all impervious surface area located on the lot or parcel.

The final determination made by the Village Board shall be made in writing and set forth, in detail, the reasons for its decision and shall inform the customer by certified mail. The Village Board may, at its discretion, require access to the property to assist in its determination.
(4) 
In reviewing a decision, the Village Board shall apply the considerations set forth in § 66.0821(4)(c), Wis. Stats.
C. 
Effective date. Any ERU adjustment or reduced multiplier granted shall thereafter be used to calculate the customer's user charges. The reduction shall only apply for the period of time subsequent to the filing of the request for adjustment. There shall be no retroactive adjustment for user charges imposed prior to the filing of the request.
