The Village of Belleville finds that the management of stormwater and other surface water discharges within and beyond the Village of Belleville 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 Belleville and/or surrounding area. In order to protect the health, safety and welfare of the public, the Village of Belleville is exercising its authority to establish a stormwater utility for stormwater management services. The Village is acting under the authority of §§ 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 Belleville. The operation of the Stormwater Utility shall be under the supervision of the Village Clerk/Treasurer.
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 stormwater and surface water management. These facilities may include, without limitation due to enumeration, surface and underground drainage facilities, sewers, 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:
CHARGE
The fee imposed under this chapter for the rendering of Stormwater Utility services by the Village.
DEVELOPED PROPERTY
A property shall be considered to be developed if:
A. 
A certificate of occupancy has been issued for a building or structure on the property or, if no certificate of occupancy has been issued, upon substantial completion of construction or final inspection; or
B. 
Construction of an improvement on the property is at least 50% completed and such construction has ceased for a period of at least three months, whether consecutive or not.
EQUIVALENT RUNOFF UNIT or ERU
The basic unit by which the Stormwater Utility charge is calculated under this chapter. It is the statistical average horizontal impervious area of residential living units within the Village of Belleville on the date of the establishment of the Stormwater Utility. The horizontal 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.
IMPERVIOUS AREA
A surface which has been compacted or covered with a layer of material so that it is highly resistant to infiltration by rainwater. The term includes, without limitation due to enumeration, all areas covered by structures, roof extensions, patios, porches, driveways, sidewalks, parking lots, pavement, gravel, compacted clay, and loading docks, all as measured on a horizontal plane.
LIVING UNIT
A room or group of rooms, including cooking accommodations, occupied by one family, and in which not more than two persons, other than members of the family, are lodged or boarded for compensation at any one time.
MULTIFAMILY UNIT
Any residential property comprised of two or more living units, including duplexes, apartments and condominiums.
NONRESIDENTIAL PROPERTY
A lot or parcel of land, with improvements such as a building, structure, other impervious area as defined in this section, grading or substantial landscaping, which is not exclusively residential as defined herein, including but not limited to commercial, industrial, institutional, mixed-use, and governmental property, and excluding publicly owned right-of-way and publicly owned or privately owned rail beds.
RESIDENTIAL PROPERTY
A lot or parcel of land developed exclusively for residential purposes, regardless of zoning classification, including single-family units, duplexes, and multifamily units. The term includes manufactured homes.
SINGLE-FAMILY UNIT
Any residential property, including manufactured homes, consisting of one dwelling unit.
STORMWATER UTILITY
The Utility established under this chapter for the purpose of managing stormwater and imposing charges for the recovery of costs connected with such stormwater management.
UNDEVELOPED PROPERTY
Property that is not developed by the addition of an improvement such as a building, structure, other impervious area as defined in this section, grading or substantial landscaping which increases stormwater runoff.
VILLAGE CLERK/TREASURER
The person appointed by the Village Board as the chief administrative officer of the Village.
By this chapter, the Village Board is establishing the rate classification and basis for computation of charge for stormwater services for each lot and parcel within the Village of Belleville. 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 office of the Village Clerk/Treasurer. All charges established pursuant to this chapter shall be fair and reasonable. Stormwater Utility charges shall be based on the number of equivalent runoff units (ERUs) assigned to each parcel. The ERU charge shall be assessed based upon the impervious area as reasonably determined by the Village Clerk/Treasurer, except for properties classified as undeveloped, which shall be exempt from the Stormwater 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 five customer classes:
(1) 
Residential: single family.
(2) 
Residential: two or more living units.
(3) 
Nonresidential.
(4) 
Undeveloped.
(5) 
Right-of-way.
B. 
Parcel classification. The Village Clerk/Treasurer shall assign a customer classification to each lot and parcel within the Village of Belleville.
C. 
Equivalent runoff unit (ERU). The ERU is established to be 2,800 square feet.
A. 
Residential: single family. The charge imposed for single-family residential properties shall be the fee for one ERU.
B. 
Residential: two or more living units. The charge imposed for residential properties with two or more living units shall be 0.67 of one ERU per living unit existing on the property, i.e., multifamily parcel charge equals 0.67 times ERU fee times the number of dwelling units.
C. 
Nonresidential. The charge imposed for nonresidential and mixed-use properties shall be the fee for one ERU multiplied by the numerical factor obtained by dividing the total square footage of impervious area of the property by the square footage of one ERU. The factor shall be rounded down to the nearest 0.1, i.e., nonresidential parcel charge equals ERU fee times parcel impervious area divided by 2,800 square feet.
D. 
Undeveloped. There shall be no charges imposed on parcels during the time period in which they are defined herein as undeveloped.
E. 
Right-of-way. Public highway, road, and rail right-of-way shall be exempt from the Stormwater Utility fee.
F. 
Minimum charge. The minimum charge for any customer charged a fee shall be equal to the fee for 1/2 of one ERU, in the absence of a credit or adjustment approved by the Village Clerk/Treasurer.
G. 
Impervious area measurement. The Village Clerk/Treasurer shall be responsible for determining the impervious area of nonresidential parcels based on the best available information, including but not limited to data supplied by the Village Assessor, Village Engineer, Village Building Inspector, Village Clerk/Treasurer, aerial photography, property owner, tenant, or developer. The Village Clerk/Treasurer may require additional information as necessary to make the determination. The number of ERUs shall be updated by the Village Clerk/Treasurer 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. Stormwater fees will be kept on file with the Village Clerk/Treasurer.
The Village Board shall adopt, by separate resolution, criteria recommended by the Village Clerk/Treasurer for providing credits and adjustments. The Village Clerk/Treasurer shall develop a manual that explains the criteria for calculating credits and adjustments and provides application materials for each. It shall be the responsibility of the property owner to prove, using the credits and adjustments manual, that a parcel is eligible for either a credit or an adjustment.
A. 
Credits.
(1) 
Eligibility. A customer may be eligible for a credit in the form of a reduced ERU multiplier for properties where all of the following conditions apply:
(a) 
The Village's cost of providing service or making service available to the property has been lessened.
(b) 
The property conforms to all applicable ordinances and standards of the Village of Belleville in effect at the time of parcel development.
(c) 
The property has been assigned a nonresidential user classification by the Village Clerk/Treasurer.
(2) 
Maximum credit. The maximum aggregate credit for any individual property is 50% of its ERU charge, regardless of how many types of credits the property qualifies for.
(3) 
Credit types. The following credits may be available to customers for properties that meet all of the eligibility criteria of Subsection A(1):
(a) 
Peak flow control credit. Credits shall be considered for customers who own and maintain stormwater management facilities such as retention or detention basins that exceed the Village's peak discharge rate requirements as set forth in Chapter 450, Stormwater Management and Erosion Control, § 450-13B(3) and (4).
(b) 
Water quality credit. Credits shall be considered for customers who own and maintain stormwater management facilities that improve the quality of runoff from the property to a degree that exceeds the Village's water quality requirements, as set forth in Chapter 450, Stormwater Management and Erosion Control, § 450-13B(1).
(c) 
Other. Other proposals may be considered on a case-by-case basis. All such proposals must either directly reduce the Village's cost of managing stormwater runoff or contribute directly towards improving the quality of runoff discharged into the Village's municipal separate storm sewer system. Such proposals may receive up to 10% credit towards the 50% maximum.
B. 
Adjustments. A customer may be eligible to have the number of ERUs assigned to its property adjusted under the conditions described below:
(1) 
Within 30 days of the submission of a request to the Village Clerk/Treasurer for an adjustment to the number of ERUs allocated to the property, the Village Clerk/Treasurer shall forward the request on to the Public Works and Parks Committee, and the Public Works and Parks Committee shall issue a written recommendation as to whether the request for adjustment should be granted, denied or granted in part. The written recommendation shall also set forth the reason or reasons for such recommendation. The recommendation shall be sent to the customer by certified mail and shall be forwarded on to the Village Clerk/Treasurer.
(2) 
Within 30 days of receipt of the written recommendation from the Public Works and Parks Committee, the Village Clerk/Treasurer shall review and approve the recommendation, unless a request is made by the Public Works and Parks Committee, Village Clerk/Treasurer, or the applicant for the Village Board to review the request. The customer shall be notified of the approval or referral by certified mail.
(3) 
If a review by the Village Board is requested, the Village Board shall determine whether the recommendation should be approved, rejected, or modified. The customer shall be allowed to present evidence at the hearing. The final determination of the Village Board shall be in writing and set forth, in detail, the reason or reasons for its decision and shall inform the customer by certified mail.
(4) 
In reviewing a recommendation, the Village Board shall apply the considerations set forth in § 66.0821(4)(c), Wis. Stats.
C. 
Review procedure.
(1) 
Undeveloped property. Properties assigned a residential or nonresidential user classification may be eligible to have the property reclassified as undeveloped if either of the following conditions exist:
(a) 
The property owner can show that the cumulative impervious area on the parcel is less than half of the impervious area of one ERU.
(b) 
The property owner can show that all living units associated with a residential parcel are accounted for by ERUs assigned to an adjacent parcel with the same owner.
(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 Village Clerk/Treasurer. The allocated ERUs may be adjusted if the owner can provide information showing the square footage calculation as determined in § 554-8C and G is incorrect.
D. 
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.
A. 
The Village shall separately account for the Stormwater Utility finances. The Village Clerk/Treasurer 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 shall be reviewed annually by the Public Works and Parks Committee and 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.
B. 
Bills. Stormwater Utility charges shall be billed to the utility account or accounts associated with each property. In the event that there are multiple utility accounts associated with a single property, the charge shall be divided among accounts based on the best available information regarding the relative number of living units or amount of impervious area associated with each account. In the event of late payment or nonpayment by utility account holders, the property owner shall be responsible for payment of all Stormwater Utility charges.
C. 
Late payment. Failure to pay the charges when due will result in a one-time late payment charge of 3% being added to bills not paid within 20 days of issuance.
D. 
Unpaid charges. Unpaid charges shall be assessed as a lien against the property pursuant to § 66.0821, Wis. Stats.
