A. 
General.
(1) 
Charges established. There is hereby established a uniform system of stormwater service charges that shall apply to each and every lot or parcel with impervious surface area within the City. It shall be the policy to establish stormwater service charges in such amount in order to pay for all or a part of the following costs relating to the Utility: operations and maintenance costs; administrative costs; contributions to a replacement fund; capital costs and debt service. The Council may establish and modify stormwater service charges as necessary so as to assure that the charges generate adequate revenues to pay the costs of the stormwater management program and that costs are allocated fairly and proportionately to all parcels in the City.
(2) 
Service charge categories.
(a) 
Volumetric service charge. A volumetric service charge shall be imposed on all property that has impervious surface area. This charge shall be related to the costs of managing stormwater runoff volume. The charge for each parcel shall be equal to the product of the service charge rate in terms of dollars per ERU and the number of volume ERUs assigned to the parcel. The number of volume ERUs assigned to each lot or parcel shall be determined based on the amount of impervious surface area.
(b) 
Pollutant loading service charge. A pollutant loading service charge shall be imposed on all property that has impervious surface area. This charge shall be related to the costs of managing pollutants in stormwater runoff. The charge for each parcel shall be equal to the product of the service charge rate in terms of dollars per ERU and the number of pollutant ERUs assigned to the parcel. The number of pollutant ERUs assigned to each lot or parcel shall be determined based on the amount of impervious surface area and the land use.
(c) 
Special charge. A special charge may be imposed on property that is in an area specially benefited by a particular stormwater management facility. This charge will be developed to reflect the benefits in a particular area that may not be appropriate to allocate to property throughout the City.
(d) 
Administrative charge. An administrative charge shall be imposed upon each property that has impervious surface area. The administrative charge shall recover a portion of costs related to stormwater flow not directly attributable to users (i.e., stormwater runoff from streets and roads) and customer costs (including accounting and billing). The administrative charge shall be imposed on each user subject to stormwater service charges and will consist of a flat fee per customer account.
[Added by Ord. No. 11-28]
(3) 
Billing and payment.
(a) 
Billing. The City shall compute the amounts due the City for stormwater service charges and shall render a statement thereof, at periodic intervals, to the owner or occupant of any premises subject to such charge.
(b) 
Payment. Property owner is held responsible for all stormwater service charges on real property owned. All stormwater bills and notices of any nature relative to the stormwater management program will be addressed to the owner and delivered to the addressee by first class mail. All amounts due hereunder shall be payable at the office of the City Clerk/Treasurer. Failure to receive a bill does not relieve a party of his/her obligation, nor relieve him/her of payment of the penalty if not paid before the due date. Claims or complaints must be made within five days from due date of bill.
[Amended by Ord. No. 10-28]
(c) 
Late charges. If stormwater service charges are not paid in full on the due date, a one-percent-per-month charge shall be made on the balance.
(d) 
Failure to receive bills. Reasonable care will be taken in the delivery of stormwater service charge bills. Failure of any person to receive bills for stormwater service charges shall not be considered an excuse for nonpayment nor shall such failure result in an extension of the period of time during which the net bill should have been paid.
(e) 
Lien on property. Unpaid stormwater service charges shall be a lien upon the property served and shall be enforced as provided in § 66.0809(3), Wis. Stats.
(4) 
Rates set by resolution. All stormwater service charge rates shall be established from time to time by written resolution of the Common Council. The rates shall be reviewed by the Common Council on an annual basis and adjusted as necessary.
B. 
Determination of ERUs.
(1) 
For purposes of imposing the service charges, all lots and parcels in the City shall be classified into the following seven customer classifications:
(a) 
Single-family residential.
(b) 
Condominium residential.
(c) 
Duplex and multifamily residential.
(d) 
Industrial.
(e) 
Commercial.
(f) 
Institutional.
(g) 
Undeveloped.
(2) 
Volume ERUs shall be calculated for each classification as follows:
(a) 
Single-family residential: one ERU per dwelling unit.
(b) 
Condominium residential. The City Engineer shall be responsible for determining the total impervious area of each condominium parcel based on the best available information, including but not limited to data supplied by the City Assessor, Building Inspector or Zoning Administrator; aerial photography; the property owner, tenant or developer; or actual on-site measurement. The total impervious area of the parcel shall be divided equally among the condominium units to determine the square feet of impervious area per unit. This amount shall be divided by the number of square feet per ERU as established by the Common Council and set forth in the Stormwater Service Charge Rate Table in § 453-6B(1) to determine the number of ERUs to assign to each unit, except that in no case shall a condominium unit be assigned less than 0.5 ERU. The number of ERUs per unit shall be rounded to the nearest 0.5 ERU.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(c) 
Duplex and multifamily residential: 0.50 ERU per dwelling unit.
(d) 
Industrial, commercial and institutional property. The City Engineer shall be responsible for determining the impervious area of each nonresidential parcel based on the best available information, including but not limited to data supplied by the City Assessor, Building Inspector or Zoning Administrator; aerial photography; the property owner, tenant or developer; or actual on-site measurement. The total impervious area of the parcel shall be divided by the number of square feet per ERU as established by the Common Council and set forth in a Stormwater Service Charge Rate Table in § 453-6B(1) to determine the number of ERUs to assign to the parcel. The number of ERUs per parcel shall be rounded to the nearest 0.5 ERU.
(e) 
Undeveloped property. For any lot or parcel that has no impervious surface area, no volume ERUs shall be assigned for purposes of imposing service charges under this article.
(3) 
Pollutant ERUs shall be calculated for each classification as follows:
(a) 
Single-family and duplex residential: one ERU per dwelling unit.
(b) 
Condominium residential. The number of volume ERUs shall be multiplied by a factor of 1.0 to determine the number of pollutant ERUs.
(c) 
Multifamily residential. The number of volume ERUs shall be multiplied by a factor of 0.80 to determine the number of pollutant ERUs.
(d) 
Industrial. The number of volume ERUs shall be multiplied by a factor of 0.90 to determine the number of pollutant ERUs.
(e) 
Commercial. The number of volume ERUs shall be multiplied by a factor of 1.10 to determine the number of pollutant ERUs.
(f) 
Institutional. The number of volume ERUs shall be multiplied by a factor of 0.50 to determine the number of pollutant ERUs.
(g) 
Undeveloped property. For any lot or parcel that has no impervious surface area, no pollutant ERUs shall be assigned for purposes of imposing service charges under this article.
(4) 
New construction. For all classifications other than single-family, duplex and multifamily residential, the construction of new or expanded buildings, driveways or other structures or improvements that add impervious surface area to the lot or parcel shall be subject to an increase in the number of ERUs assigned to a lot or parcel. The City shall recalculate the number of ERUs upon completion of new construction.
C. 
Appeals and credits.
[Amended by Ord. No. 10-01; Ord. No. 11-28]
(1) 
Nonresidential credits for the provision of stormwater mitigation facilities and/or activities. Owners of nonresidential properties that have facilities for on-site detention and runoff control or pollutant loading reduction, that undertake activities designed to reduce the quantity of or pollutant loadings in stormwater runoff from the lot or parcel, or that conduct a public education and information program designed to increase public awareness regarding the water quality impacts of stormwater runoff may be eligible for a reduction in the volumetric and/or pollutant loading service charges for their lot or parcel. In order to be eligible for a credit, the facilities or practices must exceed the City stormwater discharge standards that were in effect at the time that the lot or parcel was developed for its current use. Such property owners may apply for a review of the service charges for the lot or parcel. The amount of the credit or adjustment will be determined based on the amount of reduction in the peak rate or total annual volume of stormwater runoff or the percentage reduction in pollutant loadings that the facilities or activities are designed to achieve. No credits will be provided for the administrative charges.
(a) 
Application for credit. Any property owner desiring to apply for a reduction in the stormwater service charge shall submit an application to the Street Superintendent on forms supplied by the City. By submitting an application, the applicant is authorizing the Street Superintendent to enter the property to obtain information required for the review of the credit request. The application shall be accompanied by the following:
[1] 
Plans and studies. The applicant shall provide, as applicable, a written description of the proposed practices or public education program, hydrologic and/or hydraulic studies, plans, computations, etc., that demonstrate, to the satisfaction of the City, that the practices, programs or facilities meet the requirements for the credit requested.
[2] 
Maintenance agreement. The applicant shall provide a plan for maintenance of the facilities or practices.
[3] 
Ongoing documentation. For as long as the credit is in effect, the property owner or occupant shall supply to the City copies of any documentation required to demonstrate that the proposed practices or public education program is being carried out in accordance with the plans submitted to the City or that the facilities are being properly maintained in accordance with the maintenance agreement.
(b) 
Determination of credit. Within 30 days of receipt of a complete application and supporting documentation, the Street Superintendent shall review the application and supporting documentation and shall make a recommendation to the Public Works Commission regarding the credit request. The Public Works Commission shall review said application along with the Street Superintendent's recommendation and shall determine whether a reduction in the stormwater service charge is due the applicant. The applicant shall be provided five business days' prior written notice of the time and place of the Commission's consideration of the credit at the address listed in the application. The Commission shall base its decision on the record submitted to it at its meeting. The Street Superintendent shall notify the applicant in writing of the Commission's determination by first class mail addressed to the applicant using the address listed in the application. The credit shall be applied to the next practicable billing for stormwater service charges and all subsequent billings for as long as the facilities or practices are operated or carried out in accordance with the plans submitted with the application for the credit.
(c) 
Amount of credit. Any credit to the stormwater service charge shall be in the form of a reduction in the volume ERUs, a reduction in the pollutant ERUs, or both. The percentage reduction in the number of ERUs shall be equal to the percentage reduction in the peak rate or total annual volume of stormwater runoff or pollutant loadings beyond what is required by the City's stormwater discharge standards, up to a maximum reduction of 75% in the number of volume and/or pollutant ERUs assigned to the parcel.
[1] 
Parcels developed under current stormwater discharge standards. Parcels developed under the stormwater discharge standards in effect at the time of a credit application shall not be eligible for a reduction in stormwater service charges unless the facilities or practices exceed the City's stormwater discharge standards.
[2] 
Parcels developed prior to current stormwater discharge standards. Parcels that were developed prior to the stormwater discharge standards in effect at the time of a credit application may be eligible for a reduction in stormwater service charges if the facilities or practices exceed the City's stormwater discharge standards that were in effect when the parcel was developed. The credit shall be a percentage reduction in the number of volume and/or pollutant ERUs assigned to the parcel equal to the percentage reduction in the peak rate or total annual volume of stormwater runoff or pollutant loadings beyond what was required by the City's stormwater discharge standards in effect at the time the parcel was developed, up to a maximum reduction of 75% in the number of volume and/or pollutant ERUs assigned to the parcel.
(d) 
Appeals. The stormwater service charge, a determination of ERUs or ERU credits may be appealed by filing a written appeal with the Street Superintendent prior to the due date, if not paid, or within 30 days of payment. The appeal shall specify all bases for the challenge and the amount of the stormwater service charge the appellant asserts is appropriate. Failure to timely file an appeal waives all right to contest such charge.
[1] 
The administrative review board shall review said written appeal and shall determine whether the stormwater service charge, the ERU determination or the ERU credit is fair and reasonable or whether an adjustment or refund is due the appellant. The applicant shall be provided five business days' prior written notice of the time and place of the administrative review board's consideration of the appeal to the owner at the address listed in the appeal. The administrative review board shall base its decision on the record submitted to it at its meeting. The City Engineer shall notify the appellant in writing of the administrative review board's determination by first class mail addressed to the owner using the address listed in the appeal.
[2] 
If as a result of any appeal a refund is due the owner, such refund shall be applied as a credit on the owner's next practicable stormwater charge bill.
(2) 
Rebates to residential properties for the provision of stormwater mitigation facilities. Residential properties that provide a rain barrel or construct a rain garden to mitigate the volume of stormwater and/or pollutant loadings discharged from the property shall be eligible for a one-time rebate of $15. Property owners may apply for the rebate by completing an application supplied by the Street Superintendent and supplying a receipt or other appropriate documentation of the purchase or installation of the rain barrel or rain garden.
The City reserves the right to amend this article in part or in whole whenever it may deem necessary, but only after due notice and hearing, as provided by law.

This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection.
(2) 
A person is considered to be in violation of this article if the person connects a line conveying sewage to the MS4 or allows such a connection to continue.
The administering authority may suspend, prohibit and disconnect a person from access to the storm drain system under the following conditions:
A. 
Suspension due to illicit discharges in emergency situations. The administering authority may, without prior notice, suspend MS4 discharge access to a person when such suspension is necessary to stop an actual or threatened discharge which presents or may present imminent and substantial danger to the environment, or to the health or welfare of persons, or to the MS4 or waters of the United States. If the violator fails to comply with a suspension order issued in an emergency, the administering authority may take such steps as deemed necessary to prevent or minimize damage to the MS4 or waters of the United States, or to minimize danger to persons.
B. 
Suspension due to the detection of illicit discharge. Any person discharging to the MS4 in violation of this article may have its MS4 access terminated if such termination would abate or reduce an illicit discharge. The administering authority will notify a violator of the proposed termination of its MS4 access. The violator may petition the administering authority for a reconsideration and hearing.
C. 
Suspension due to unauthorized connection to MS4. A person commits a violation of this article if the person reinstates MS4 access to premises terminated pursuant to this section without the prior approval of the administering authority.
Any person subject to an industrial or construction activity WPDES stormwater discharge permit shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the administering authority prior to the allowing of discharges to the MS4.
A. 
Applicability. This section applies to all facilities that have stormwater discharges associated with industrial activity, including construction activity.
B. 
Access to facilities.
(1) 
The administering authority shall be permitted to enter and inspect facilities subject to regulation under this article as often as may be necessary to determine compliance with this article. If a discharger has security measures in force which require proper identification and clearance before entry into its premises, the discharger shall make the necessary arrangements to allow access to representatives of the administering authority.
(2) 
Facility operators shall allow the administering authority ready access to all parts of the premises for the purposes of inspection, sampling, examination and copying of records that must be kept under the conditions of a WPDES permit to discharge stormwater and the performance of any additional duties as defined by state and federal law.
(3) 
The administering authority shall have the right to set up on any permitted facility such devices as are necessary in the opinion of the administering authority to conduct monitoring and/or sampling of the facility's stormwater discharge.
(4) 
The administering authority has the right to require the discharger to install monitoring equipment as necessary. The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the discharger at its own expense. All devices used to measure stormwater flow and quality shall be calibrated to ensure their accuracy.
(5) 
Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the operator at the written or oral request of the Street Superintendent and shall not be replaced. The costs of clearing such access shall be borne by the operator.
[Amended by Ord. No. 10-01]
(6) 
Unreasonable delays in allowing the administering authority access to a permitted facility is a violation of a stormwater discharge permit and of this article. A person who is the operator of a facility with a WPDES permit to discharge stormwater associated with industrial activity commits an offense if the person denies the administering authority reasonable access to the permitted facility for the purpose of conducting any activity authorized or required by this article.
(7) 
If the administering authority has been refused access to any part of the premises from which stormwater is discharged, and he/she is able to demonstrate probable cause to believe that there may be a violation of this article, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program designed to verify compliance with this article or any order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the administering authority may seek issuance of a special inspection warrant or a search warrant from any court of competent jurisdiction.
The administering authority may provide requirements identifying best management practices for any activity, operation or facility which may cause or contribute to pollution or contamination of stormwater, the storm drain system, or waters of the United States. The owner or operator of a commercial or industrial establishment shall provide, at its own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal storm drain system or watercourses through the use of these structural and nonstructural BMPs. Further, any person responsible for a property or premises which is, or may be, the source of an illicit discharge may be required to implement, at said person's expense, additional structural and nonstructural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system. Compliance with all terms and conditions of a valid WPDES permit authorizing the discharge of stormwater associated with industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this section. These BMPs shall be part of a stormwater pollution prevention plan (SWPP) as necessary for compliance with requirements of the WPDES permit.
Every person owning property through which a watercourse passes, or such person's lessee, shall keep and maintain that part of the watercourse within the property free of trash, debris, excessive vegetation, and other obstacles that would pollute, contaminate or significantly retard the flow of water through the watercourse. In addition, the owner or lessee shall maintain existing privately owned structures within or adjacent to a watercourse, so that such structures will not become a hazard to the use, function or physical integrity of the watercourse.
Notwithstanding other requirements of law, as soon as any person responsible for a facility or operation or responsible for emergency response for a facility or operation has information of any known or suspected release of materials which are resulting or may result in illegal discharges or pollutants discharging into stormwater, the storm drain system, or water of the United States, said person shall take all necessary steps to ensure the discovery, containment and cleanup of such release. In the event of such a release of hazardous materials, said person shall immediately notify emergency response agencies of the occurrence via emergency dispatch services. In the event of a release of nonhazardous materials, said person shall notify the administering authority in person or by phone or facsimile within 24 hours of becoming aware of the release. Notifications in person or by phone shall be confirmed by written notice addressed and mailed to the administering authority within three business days of the phone notice. If the discharge of prohibited materials emanates from a commercial or industrial establishment, the owner or operator of such establishment shall also retain an on-site written record of the discharge and the actions taken to prevent its recurrence. Such records shall be retained for at least three years.
A. 
Notice of violation. Whenever the administering authority finds that a person has violated a prohibition or failed to meet a requirement of this article, the administering authority may order compliance by written notice of violation to the responsible person. Such notice may require without limitation:
(1) 
The performance of monitoring, analyses and reporting;
(2) 
The elimination of illicit connections or discharges;
(3) 
That violating discharges, practices, or operations shall cease and desist;
(4) 
The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property;
(5) 
Payment of a fine to cover administrative and remediation costs; and
(6) 
The implementation of source control or treatment BMPs.
B. 
Notice of abatement. If abatement of a violation and/or restoration of affected property is required, the notice shall set forth a deadline within which such remediation or restoration must be completed. Said notice shall further advise that, should the violator fail to remediate or restore within the established deadline, the work will be done by a designated governmental agency or a contractor, and the expense thereof shall be charged to the violator.
Any person receiving a notice of violation may appeal the determination of the administering authority. The notice of appeal must be received within five days from the date of the notice of violation. Hearing on the appeal before the City of Watertown Public Works Commission, which is designated as the appropriate authority to hear and determine such appeal, shall take place within 30 days from the date of receipt of the notice of appeal. The decision of the City of Watertown Public Works Commission shall be final, subject to appeal to a court of competent jurisdiction under law.
If the violation has not been corrected pursuant to the requirements set forth in the notice of violation or, in the event of an appeal, within 10 days of the decision of the City of Watertown Public Works Commission upholding the decision of the administering authority, then representatives of the administering authority shall enter upon the subject private property and are authorized to take any and all measures necessary to abate the violation and/or restore the property. It shall be unlawful for any person, owner, agent or person in possession of any premises to refuse to allow the government agency or designated contractor to enter upon the premises for the purposes set forth above.
Within 15 days after abatement of the violation, the owner of the property will be notified of the cost of abatement, including administrative costs. If the amount due is not paid within 60 days after receipt of the final bill, the charges shall become a special assessment against the property and shall constitute a lien on the property for the amount of the assessment. Any person violating any of the provisions of this article shall become liable to the administering authority by reason of such violation. Interest may be assessed on the balance beginning on the 31st day following notice to the property owner of the cost of the abatement.
It shall be unlawful for any person to violate any provision or fail to comply with any of the requirements of this article. If a person has violated or continues to violate the provisions of this article, the administering authority may petition for a preliminary or permanent injunction restraining the person from activities which would create further violations or compelling the person to perform abatement or remediation of the violation.
In lieu of enforcement proceedings, penalties and remedies authorized by this article, the administering authority may impose upon a violator alternative compensatory actions, such as storm drain stenciling, attendance at compliance workshops, creek cleanup, etc.
In addition to the enforcement processes and penalties provided, any condition caused or permitted to exist in violation of any of the provisions of this article is a threat to public health, safety and welfare and is declared and deemed a nuisance and may be summarily abated or restored at the violator's expense, and/or a civil action to abate, enjoin or otherwise compel the cessation of such nuisance may be taken.
Any person that has violated or continues to violate this article shall be liable to criminal prosecution to the fullest extent of the law and shall be subject to a criminal penalty adopted by the Wisconsin Legislature and imposed by the Wisconsin Department of Natural Resources at its discretion. This criminal penalty shall be on file in the offices of the Police Chief and the City Clerk/Treasurer.
The administering authority may recover any and all attorney's fees, court costs and other expenses associated with enforcement of this article, including sampling and monitoring expenses.
The remedies listed in this article are not exclusive of any other remedies available under any applicable federal, state or local law, and it is within the discretion of the administering authority to seek cumulative remedies.
