City of Mukilteo


There are many privately-owned stormwater facilities in the City.  These ponds and underground vaults are the responsibility of private property owners, including Homeowner’s Associations, single family residences, and commercial properties.  If you have stormwater infrastructure on your property and are unsure of the maintenance responsibility, please contact the City’s Surface Water Technician at (425) 263-8082.

Excerpt from Mukilteo Municipal Code

13.12.210 Maintenance, repair and operation of the stormwater system.

A.    Public Stormwater Facilities. The city shall be responsible for operating, maintaining, repairing and replacing public stormwater facilities and the public stormwater system.

B.    Private Stormwater Facilities. Every property owner and/or person responsible for a private stormwater facility shall be responsible for operating, maintaining, repairing and replacing any private stormwater facility located on said property or under their control. Upon written notice by the city, a private stormwater facility shall be promptly repaired and/or brought up to applicable standards by the property owner or the person responsible for said facility. If a private stormwater facility serves multiple lots and the responsibility for maintenance has not been specified on a subdivision plat, short plat or other legal document, maintenance, operation and repair responsibility shall rest with the homeowners’ association, if one exists, or otherwise with the properties served by the facility, or finally, with the owners of the property on which the facilities are located.

C.    Assumption of Maintenance Responsibility by City. The city may, at its sole discretion, agree to assume the maintenance of a private stormwater facility; provided, that the city may not agree to maintain any private stormwater facility unless all of the following conditions are met to the director’s satisfaction:

  1. Maintenance of the facility by the city would provide a public benefit; and
  2. Necessary and appropriate property rights and access are provided to the city in accordance with this chapter; and
  3. The city has adequate resources, now and in the foreseeable future, to maintain the facility; and
  4. At the time the maintenance of the facility is assumed by the city, the facility is in good repair and order, and is functioning in the manner that was intended when designed; and
  5. Owners requesting city assumption under this section shall submit a statement supporting criteria in subsections (C)(1) through (4) of this section; and
  6. The director has obtained a binding agreement, satisfactory to the city attorney, describing the terms and conditions under which the private facility shall be maintained by the city.

Unless directly caused by the sole negligence of the city, the city shall not be responsible for repair or replacement of failed structures, parts, or components of a private stormwater facility (even if the city has accepted the maintenance of said facility), nor for maintenance or rehabilitation of vegetation (except as may be needed, in the city’s sole discretion, for the detention and/or water quality function of the facility). Following assumption by the city of the maintenance of a private stormwater facility, the private property owner(s) shall continue to be responsible for the entire costs of any repair to and/or replacement of the facility.

D.    New Private Stormwater Facilities. In new subdivisions, short plats, and binding site plans, operation and maintenance responsibility for private stormwater facilities shall be specified on the face of the subdivision, short plat or binding site plan to the satisfaction of the director before final approval of the subdivision, short plat or binding site plan may be granted.

E.    Maintenance Standards. Stormwater facilities shall be maintained so that they function as designed and intended. Maintenance shall be performed in accordance with the city’s maintenance standards and in accordance with the project operation and maintenance plan, if one is developed pursuant to this chapter.

F.    Maintenance and Correction of Drainage Problem by City.

  1. When the director determines that the failure to maintain stormwater facilities necessitates an immediate action to remedy an imminent threat to public health, welfare and water quality, the city may perform the necessary construction or remedial work. No notice shall be required under such circumstances. The property owner, the property owners’ association, or project proponent shall be responsible for all costs associated with the work.
  2. The director may order the removal, correction or replacement of any improperly constructed or maintained storm drainage or erosion control system that the director has previously reviewed and approved. The property owner, the property owner’s association, or project proponent shall be responsible for all costs associated with the removal, construction or replacement.
  3. The property owner, the property owners’ association, and project proponent are jointly and severally liable for all costs, including a reasonable attorney’s fee, incurred in any remedial action performed by the city under this chapter. The city may record a lien on the property owned by such jointly and severally liable entities for payment of costs plus reasonable attorney’s fees. Interest shall accrue on costs and fees at the same rate as for real estate tax delinquencies and shall commence on the date of completion of remedial action.
  4. The city assumes no liability for performing any action authorized under this section nor does the city take on responsibility for future maintenance or repair associated with such action.

  1. As an alternative to issuing a notice and order, the director may issue a warning notice to the owner or operator of the source of the violation, the person in possession of the property where the violation originates and/or the person otherwise causing or responsible for the violation of this chapter if, in the opinion of the director, the apparent violation can be voluntarily corrected within a reasonable amount of time.

  5. The recipient(s) of a warning notice shall respond to the notice within thirty calendar days from the date of receiving the notice, unless the notice specifies a different time period. The recipient(s) may respond to a warning notice once in any of the following ways:
    1. Cure the Apparent Violation in a Timely Manner. The recipient(s) of a warning notice may cure the apparent violation described in the notice within the time period specified in the notice. In such event, the recipient shall promptly notify the city when the apparent violation has been cured, and the city shall promptly inspect the site for compliance.
    2. Request for Alternative Corrective Action. The recipient(s) of a warning notice may submit a written request to the city proposing an alternative to the city’s recommended corrective action to cure the apparent violation. The request shall describe the proposed alternative correction action and how it is functionally equivalent to the corrective action recommended by the city. The director may agree to the request for an alternative corrective action.

    3. Request Additional Time. The recipient(s) of a warning notice may submit a written request to the city requesting additional time to cure the apparent violation. Any such request shall explain why the circumstances surrounding the apparent violation support the request for additional time. The request shall propose a timeline or schedule pursuant to which the responsible person(s) will cure the apparent violation. The director may agree to a reasonable proposal requesting additional time. The director’s decision to grant, deny, or partially grant a request for additional time shall be in writing. If the violation is not cured by the new deadline, the director may issue a notice and order as provided in subsection A of this section.
    4. Contest the Warning Notice. The recipient(s) of a warning notice may contest the accuracy, validity, or appropriateness of the notice by requesting the director amend the warning by providing a written request to the director within thirty calendar days from the date of receiving the warning notice. Any such request is limited to one opportunity.
  6. The director may issue a notice and order for a violation of this chapter irrespective of any previous issuance of a warning notice regarding the violation.

C.    Monetary Penalties and Costs.

  1. Whenever a violation of this chapter occurs, the director may impose a monetary penalty upon the person(s) responsible for the violation. The amount of such monetary penalty shall be calculated pursuant to this subsection, and set forth in a notice and order issued pursuant to subsection A of this section.
  2. Monetary penalties shall be determined as follows:
    1. The base amount of monetary penalty shall be $5,000 per violation for a constructed stormwater facility found to be in violation of this chapter or standards required hereunder. If there are multiple problems with the same constructed stormwater facility, said problems shall be treated as a single violation for purposes of calculating the amount of base penalty imposed. If more than one constructed stormwater control facility is located on a particular property, a five thousand dollar base penalty shall be imposed for each constructed stormwater facility that is in violation of this chapter.
    2. The base amount of monetary penalties for violations resulting in the discharge of pollutants and/or prohibited discharges, or failure to implement and properly maintain required source control BMPs, shall be determined by the director by reference to the penalty criteria contained in subsection D of this section and the penalty schedule contained in subsection E of this section. For repeat violators and repeat violations, the base penalty amount resulting from this calculation shall be doubled.
  3. In addition to the base penalty amount, the person(s) responsible for a violation may also be required to reimburse the city for the costs incurred by the city in investigating the violation and enforcing remediation of the violation, including any laboratory costs. If the full amount of reimbursable costs incurred by the city due to a particular violation is not known at the time an original notice and order is issued, a revised notice and order including such costs in the monetary penalty may be issued to the responsible person(s) once said costs are known.
  4. If there is more than one person responsible for a given violation, all responsible persons shall be jointly and severally liable to the city for the entire amount of monetary penalties imposed with respect to the violation.

F.    Response to Notice and Order.

  1. The recipient(s) of a notice and order shall respond to the notice and order within thirty calendar days from the date of receiving the notice and order, unless the notice and order specifies a longer time period. The recipient(s) may respond to a notice and order in any of the following ways:
    1. Cure the Violation in a Timely Manner. The recipient(s) of a notice and order may cure the violation described in the notice and order within the time period specified in the notice and order. In such event, the recipient shall promptly notify the city when the violation has been cured, and the city shall promptly inspect the site for compliance. If the city determines the violation has been timely cured, the monetary penalty specified in the notice and order may be partially or fully waived, at the discretion of the director, as provided in subsection (L)(1)(b) of this section.
    2. Request Additional Time. The recipient(s) of a notice and order may submit a written request to the city requesting additional time to cure the violation. Any such request shall explain why the circumstances surrounding the violation support the request for additional time. The request shall propose a timeline or schedule pursuant to which the responsible person(s) will cure the violation. The director may agree to a reasonable proposal requesting additional time. In connection with approving a request for additional time under this subsection, the director may also agree that if the violation is cured by the new deadline, the amount of the monetary penalty specified in the notice and order may be reduced by an appropriate amount, consistent with subsection L of this section. The director’s decision to grant, deny, or partially grant a request for additional time shall be in writing, as shall any associated decision to conditionally reduce the monetary penalty. If the violation is not cured by the new deadline, then any reduction in the amount of monetary penalties granted pursuant to this subsection shall be void and the original amount of monetary penalties specified in the notice and order shall be due and owing.
    3. Request a Reduction in the Amount of Monetary Penalty. The recipient(s) of a notice and order may submit a written request to the city requesting a reduction in the amount of the monetary penalty specified in the notice and order. Any such request shall explain why the circumstances surrounding the violation support the request to reduce the amount of the monetary penalty. The director may agree to reduce the amount of the monetary penalty by an appropriate amount, consistent with subsection L of this section, on the condition that the violation must be cured by the deadline specified in the notice and order or such other deadline as the director may deem reasonable. The director’s decision to grant, deny, or partially grant a request for a reduction in the amount of any monetary penalty shall be in writing. If the director’s written decision grants or partially grants a reduction in the amount of a monetary penalty, then the decision shall also specify the deadline by which the violation must be cured in order for the reduction in monetary penalties to be effective. If the violation is not cured by the specified deadline, then any reduction in the amount of monetary penalties granted pursuant to this subsection shall be void and the original amount of monetary penalties specified in the notice and order shall be due and owing.
    4. Request Additional Time and a Reduction in the Amount of Monetary Penalty. The recipient(s) of a notice and order may submit a written request to the city requesting both additional time in which to cure the violation and a reduction in the amount of the monetary penalty specified in the notice and order. Any such request shall explain why the circumstances surrounding the violation support both the request for additional time and the request to reduce the amount of the monetary penalty. The request shall propose a timeline or schedule pursuant to which the recipient of the notice and order will cure the violation. The director may agree to a reasonable proposal (a) requesting additional time, and/or (b) to reduce the monetary penalty by an appropriate amount, consistent with subsection L of this section, on the condition that the violation must be cured by the applicable deadline. The director’s decision to grant, deny, or partially grant a request for both additional time and a reduction in the amount of monetary penalties shall be in writing. If the director’s written decision grants or partially grants a reduction in the amount of a monetary penalty, then the decision shall also specify the deadline by which the violation must be cured in order for the reduction in monetary penalties to be effective. If the violation is not cured by the specified deadline, then any reduction in the amount of monetary penalties granted pursuant to this subsection shall be void and the original amount of monetary penalties specified in the notice and order shall be due and owing.
    5. Appeal the Notice and Order. The recipient(s) of a notice and order may contest the accuracy, validity, or appropriateness of the notice and order by appealing the notice and order to the hearing examiner within thirty calendar days from the date of receiving the notice and order. Any such appeal must be made in writing and must contain the elements described in Section 17.13.090, except that no filing fee shall be required. The appeal documents shall be delivered directly to the city clerk by mail, personal delivery or other method, as provided in Section 17.13.090.
