A. 
The Stormwater Utility finances shall be accounted for in a separate Stormwater Utility Enterprise Fund by the City. All income and revenues shall be retained by the Stormwater Utility Enterprise Fund. The Stormwater Utility shall prepare an annual budget, which is to include all operation and maintenance costs, debt service and other costs related to the operation of the Stormwater Utility. The annual budget is subject to approval by the Common Council.
A. 
Every person shall pay the applicable Onalaska stormwater service charge when due for each property by that person.
B. 
The basis for computations of the charge for stormwater services to lots and parcels of land within the City is established under this section. The amount of charge to be imposed, the establishment of formulas for the calculation of charges, the creation of customer classifications for the imposition of charges, and changes in such charges, formulas and customer classifications shall be consistent with this section. Each year the Common Council shall determine the value of one ERU based upon the applicable year's adopted City Budget and this section, and shall certify such value to the City Clerk/Treasurer and Common Council. All charges established pursuant to this section shall be fair and reasonable. A schedule of current charges shall be maintained and on file in the Department of Public Works.
C. 
Charges shall be imposed to recover all or a portion of the costs of the Stormwater Utility. Such charges may include, but are not limited to, the following components:
1. 
Base component. The base component shall include the Stormwater Utility's estimated annual administrative and management costs, water quality costs, and other costs not in the components described below. The base rate shall be calculated by taking the sum of all base component costs and dividing that by the estimated number of billable ERUs.
2. 
Operations and maintenance component. Operation and maintenance component shall include the Stormwater Utility's estimated annual operation and maintenance costs for the City's stormwater management system. The operation and maintenance rate shall be determined by:
a. 
Taking the sum of all operation and maintenance component costs;
b. 
Dividing that amount by the ERUs remaining after the ERUs that the City, upon user application, has determined need not pay operation and maintenance Component costs; and
c. 
Making appropriate adjustments to the rate to account for factors such as changes in stormwater reserves.
3. 
Capital and debt service component. Capital and debt service component cost shall include the capital costs and debt service payments for the City's stormwater conveyance system, including retention and detention facilities. The capital and debt service rate shall be determined by:
a. 
Taking the sum of all capital and debt service component costs;
b. 
Dividing that amount by the ERUs remaining after the ERUs which the City, upon user application, has determined need not pay capital and debt service component costs; and
c. 
Making appropriate adjustments to the rate to account for factors such as changes in stormwater reserves.
D. 
Credits or adjustments may be available to individual property owners in the nonresidential and multifamily customer classes. It shall be the burden of the property owner to request such a credit and to demonstrate that the property owner has met the requirements as listed in the Stormwater Utility credit policy to a reasonable degree of certainty with evidence that a fee adjustment is warranted. The credits or adjustments shall be applied to the operation and maintenance component costs and the capital and debt service component costs. The base component shall be charged to all properties regardless of credits unless the property is regulated by a separate municipal stormwater discharge permit (WPDES). The Stormwater Utility credit policy, as issued by the City of Onalaska Common Council, shall be applied to all credit applications. All applications for credit or adjustments shall be reviewed by the City Engineer, and the City Engineer may reduce the measured impervious area after taking into consideration the demonstrated reduction in stormwater volume. Credits or adjustments may be applied to applicable properties based upon the following criteria:
1. 
An adjustment may be applicable in some or all of a customer's property, provided:
a. 
Stormwater runoff from the property does not discharge directly or indirectly to or through any form of conveyance system owned or operated by the Stormwater Utility; and
b. 
The drainage from the property is not in violation of any environmental code or federal, state or local surface water drainage requirements.
2. 
Credits may be granted to owners of properties who have significantly reduced the impacts of stormwater discharge or stormwater quality to the Stormwater Utility system. Owners of property which discharge all or a portion of their stormwater into privately owned and maintained retention and detention ponds shall receive a prorated credit to the number of ERUs assigned to their property as outlined in the Stormwater Utility credit policy. No owner may be given a credit in excess of 50% of their total number of ERUs for the operation and maintenance component and capital and debt service component.
3. 
Prior to receiving a credit or adjustment, the City Engineer or designee shall be allowed access to the property to determine the amount of credit or exemption to be granted.
A. 
A property owner shall be responsible for timely submitting a fully completed and accurate stormwater utility service application at the time a building permit is issued or a site plan review is conducted. The application shall be made on a form prescribed by the City and provided with each application for a building permit or application for site plan review. Failure to submit such stormwater utility service application or providing false information on such form shall constitute a violation of this section.
