A.    The purpose of this chapter is to promote sound development guidelines and construction procedures which respect and observe the city’s watercourses; to minimize water quality degradation and control the sedimentation of creeks, streams, ponds and other water bodies; to protect property owners adjacent to developing and developed land from increased runoff rates which could cause erosion of abutting property; to protect downstream owners; to preserve and enhance the suitability of waters for recreation; to preserve and enhance the aesthetic quality of the waters; to maintain and protect ground water resources; to minimize adverse effects of alterations in ground water quantities, locations and flow patterns; to ensure the safety of public roads and rights-of-way; and to decrease drainage-related damage to public and private property.

B.    This chapter is enacted pursuant to the police power of the city to protect and preserve the public health, safety and general welfare and in compliance with the Federal Clean Water Act (33 U.S.C. Section 1251 et seq.) and the requirements of the city’s National Pollution Discharge Elimination System (NPDES) Phase II permit issued by the Washington State Department of Ecology. Its provisions shall be liberally construed to accomplish the purposes of the program and the protection and preservation of the public health, safety and general welfare.

C.    It is the intent of this chapter to provide for and to promote the public health, safety and general welfare of the citizens and not to create or otherwise establish or designate any particular class or group of persons who will or should be specially protected or benefited. This chapter shall not be construed to create any specific rights in any individual nor to create any duty owed by the city toward any individual or class of persons.

D.    It is the intent of this chapter to place the obligation of compliance with the requirements of this chapter upon the owner and/or operator of a stormwater facility, whether public or private. Nothing contained in this chapter is intended to be nor shall it be construed to create or form the basis for liability on the part of the city, or its officers, employees or agents, for any injury to persons or damage to property resulting or arising from the act, omission or failure of the owner or operator of any stormwater facility to comply with the provisions of the program, or by reason or in consequence of any act or omission in connection with the implementation or enforcement of this chapter by the city, or their officers, employees or agents.

K.    Coordinate as necessary or advisable with private and public stakeholders, and federal, state, county, city and regional governments. (Ord. 1458 § 1 (Exh. A), 2022; Ord. 1390 § 1 (Exh. A) (part), 2016: Ord. 1222 § 2 (Exh. A) (part), 2009)

13.12.030 Definitions.

Words and phrases when used in this chapter shall have the meanings as defined in Chapter 17.08, Definitions. Words not defined shall have their usual meanings as commonly understood. (Ord. 1458 § 1 (Exh. A), 2022; Ord. 1390 § 1 (Exh. A) (part), 2016: Ord. 1222 § 2 (Exh. A) (part), 2009)

13.12.040 Ecology Manual adopted.

The city hereby adopts the thresholds, definitions, minimum requirements and exceptions, adjustment and variance criteria found in Appendix I of the NPDES Phase II Municipal Stormwater Permit, including the mandatory incorporated provisions of the Ecology Manual. Authority is hereby delegated to the director to adopt such administrative changes or amendments to the Ecology Manual as necessary or appropriate to conform to local circumstances; provided, that such changes and amendments shall be consistent with the purpose and intent of this chapter and in no case be less stringent than currently adopted standards. The director shall at all times maintain and make available for public inspection the Ecology Manual, as amended. (Ord. 1458 § 1 (Exh. A), 2022; Ord. 1390 § 1 (Exh. A) (part), 2016: Ord. 1222 § 2 (Exh. A) (part), 2009)

13.12.050 Establishment of regional facilities.

In the event that public benefits would accrue due to modification of the drainage plan for the subject property to better implement the recommendations of the adopted storm drainage study, the director may recommend that the city should assume responsibility for the design, construction, operation and maintenance of the drainage facilities, or any increment of the facilities on the subject property. Should establishment of a regional detention facility at a location not contained in the subject property entail a greater public benefit, the director may require the applicant to participate in the cost of such an off-site regional detention facility in lieu of constructing on-site detention facilities. Such decision shall be made concurrently with review and approval of the plan as specified in Section 13.12.160. In the event that the city decides to assume responsibility for all or any portion of the design, construction, operation and maintenance of the facilities, the applicant will be required to contribute a pro rata share to the construction and maintenance cost of the facilities. The applicant may be required to supply additional information at the request of the director to aid in the determination by the city. (Ord. 1458 § 1 (Exh. A), 2022; Ord. 1390 § 1 (Exh. A) (part), 2016: Ord. 1222 § 2 (Exh. A) (part), 2009)

A.    All development within city jurisdiction shall be served by the city stormwater system except where otherwise provided in the Mukilteo Municipal Code. Developers are required to extend the existing system across the full frontage of the property being developed where consistent with city plans, stormwater minimum requirements, and upon approval of construction and conveying or deeding the system so constructed to the city. Joint participation by the city may be applicable where oversizing is deemed appropriate in the city’s comprehensive stormwater plan.

B.    Private Installation. The property owner shall be responsible for installation of all new stormwater facilities required by this chapter. Installation shall only be authorized through an approved stormwater permit issued under this chapter.

C.    City Installation. The city may, as it determines necessary or advisable and subject to budgetary limitations, install stormwater facilities to facilitate development, coordinate with other city projects, or for other city purposes, and may recover its costs, including interest, through a facility connection charge.

D.    Costs. All installation costs shall be the responsibility of the property owner; provided, that if the city requires a property owner to install an oversized stormwater facility, the city will compensate the property owner for the difference in cost between the normally sized facility and the oversized facility based on the lowest of three bids furnished by the property owner from reputable licensed contractors; and provided further, that a property owner who constructs a public stormwater facility or system extension that directly benefits another property may request a latecomer’s agreement under Section 13.12.130. (Ord. 1458 § 1 (Exh. A), 2022; Ord. 1390 § 1 (Exh. A) (part), 2016: Ord. 1222 § 2 (Exh. A) (part), 2009)

13.12.130 Latecomer’s agreement—New streets, street extensions, storm sewer and related improvements.

A.    Purpose. This section is intended to implement and thereby make available to the city and the public the provisions of Chapters 35.72 and 35.91 RCW as presently constituted or as may be subsequently amended.

B.    Application Authorized—Term. Any applicant (developer) utilizing private funds to install street, storm sewer or other related improvements and appurtenances may apply to the city to establish a latecomer’s agreement for recovery of a pro rata share of the cost of constructing said public improvements from the owners of the other properties that will later derive a benefit from said improvements. No reimbursement agreement or latecomer’s agreement under Chapter 35.72 RCW shall extend for a period longer than fifteen years, unless extended in accordance with RCW 35.72.020(2). No reimbursement agreement or latecomer’s agreement under Chapter 35.91 RCW shall extend for a period longer than twenty years, unless extended in accordance with RCW 35.91.020(4). The city council shall have discretion to authorize or not to authorize latecomer’s agreements for other reasons on a case-by-case basis.

C.    Rights and Nonliability of City. The city reserves the right to refuse to enter into any latecomer’s agreement or to reject any application therefor at the city’s sole discretion. No latecomer’s agreement shall be legally effective until the city council adopts an ordinance approving the latecomer’s agreement at a public meeting of the city council. All applications for latecomer’s agreements shall be made on the basis that the applicant releases and waives any claims for any liability of the city in the establishment and enforcement of any latecomer’s agreements. The city shall not be responsible for locating any beneficiary or survivor entitled to benefits by or through latecomer’s agreements.

D.    Application Requirements. All applications, procedures and policies for latecomer’s agreements shall be approved and established by the mayor or the mayor’s designee and shall be accompanied by all nonrefundable application fees set forth in the city’s land use fee schedule or in any fee schedule subsequently adopted by the city. The latecomer’s agreement application must be submitted for city review prior to city acceptance of the improvements for which reimbursement is sought.

E.    Eligibility of Applicants. In order to be eligible to apply for a latecomer’s agreement, the applicant shall be in compliance with all city ordinances, rules and regulations relating to any development application or project associated with the proposed latecomer’s agreement.

F.    Procedures for Latecomer’s Agreements.

1.    The applicant (developer) proposing to establish a latecomer’s agreement shall submit a preliminary estimate and proposed reimbursement/benefit area (“benefited area”) boundaries as part of the engineering drawings submitted as part of the initial project application. Following utility/street installation/construction and city acceptance of same, the applicant (developer) requesting a latecomer’s agreement shall submit detailed construction plans and drawings for the project together with a site plan, map or diagram of the proposed benefited area, which documents shall be prepared and stamped by a licensed professional civil engineer and which shall identify the proposed boundaries of the benefited area and each separately owned parcel of real property located within the benefited area and the location of the project in relation to all parcels of real property located within the benefited area, and an itemized cost estimate for the entire project based upon the plans of the civil engineer from which reimbursable costs shall be estimated, together with assessor’s reports (including names and mailing addresses) of all real properties within the benefited area, and such other information and documents as the city may require.

2.    The applicant (developer) requesting a latecomer’s agreement shall submit, along with the application, the nonrefundable application fee set forth in the city’s land use fee schedule, which application fee shall be applied to the city’s legal, engineering and administrative costs in processing the application for the latecomer’s agreement, which costs shall be included as reimbursable costs in the latecomer’s agreement; provided, that whenever the city’s actual engineering, legal, administrative or other costs exceed the amount of the initial nonrefundable application fee, the applicant shall be required to pay to the city the estimated cost of said excess costs and the city shall not be obligated to continue to process the application until such costs have been paid to the city in full. In addition, the city will charge an eight percent administrative fee for handling each transaction, said fee to be deducted from all latecomer’s fees collected.

3.    The mayor or the mayor’s designee will determine the boundaries of the benefited area based upon a determination of which parcels of real property are within the benefited area and which of such parcels will not contribute to the original cost of street and utility system improvements and who may subsequently connect to, drain to or use the same including uses connected to laterals or branches connecting thereto.

4.    The mayor or the mayor’s designee, based on information submitted by the applicant with the application for the latecomer’s agreement, will establish an estimate of the pro rata share of costs. The director or the director’s designee may require the applicant to supply the city with engineering costs and/or competitive construction bids prior to the establishment of the estimate.

5.    The director or the director’s designee, at the director’s discretion, shall have the right to require the applicant to pay, in advance, the costs of an appraiser retained by the city to assist the director or the director’s designee in formulating the assessment reimbursement area and the estimate of the proration of costs.

6.    Prior to the execution of a contract with the applicant for a latecomer’s agreement, the mayor or the mayor’s designee shall deliver by certified mail a notice required by the applicable state law to all property owners within the benefited area stating the preliminary boundaries of the benefited area and pro rata share of assessments for costs of the project, and stating that each property owner has the right to request a public hearing to be held before the city council to consider the application for the latecomer’s agreement, including the preliminary boundary of the benefited area and preliminary assessment of costs to the affected property owners. If no hearing is requested, the city council may consider and take final action on the latecomer’s agreement at any public meeting held more than twenty days after notice was mailed to the affected property owners. If the city receives a request for a public hearing, a public hearing will be held by the city council thereafter, with notice of the public hearing given to all affected property owners at least twenty days in advance of the hearing. At the hearing, the city council shall determine whether to accept, reject or modify the proposed latecomer’s agreement, or any provision thereof, including but not limited to the boundaries or proration of costs. If the city council accepts the latecomer’s agreement, the council shall establish the boundaries of the benefited area; provided, that the city council may only modify the boundary of the benefited area upon prior notice to the owners of the property affected by the modification. The decision of the city council shall be final and determinative.

7.    The latecomer’s agreement shall have no legal effect and shall be null and void unless it is recorded with the Snohomish County auditor within thirty days of the final execution of the agreement. It shall be the sole responsibility of the applicant for the latecomer’s agreement to record said agreement at the latecomer’s expense.

8.    Once recorded, the latecomer’s agreement shall be binding on all owners of record of all real properties located within the benefited area who are not party to the latecomer’s agreement.

9.    Every two years from the date the contract is executed a property owner entitled to reimbursement under this section shall provide the appropriate county, city, or town with information regarding the current contract name, address, and telephone number of the person, company, or partnership that originally entered into the contract. If the property owner fails to comply with the notification requirements of this subsection within sixty days of the specified time, then the contracting county, city, or town may collect any reimbursement funds owed to the property owner under the contract. Such funds must be deposited in the capital fund of the county, city, or town.

10.    The city reserves the right to participate in these agreements.

11.    The city shall neither issue a building permit nor similar development permit or approval unless the city has received full payment of the assessment applicable to the property connecting to or using the street and/or utility system improvements constructed by the applicant (developer); provided, if the validity of the latecomer’s agreement is challenged, the city reserves the right to issue a permit, approval or permission without liability or prejudice to the city, and without prejudice to any other rights or remedies available to the applicant (developer) under this section or otherwise at law or in equity.

12.    Segregation. The director shall, upon the request of any property owner within the benefited area, segregate the assessment among portions of a particular parcel that is legally subdivided. The segregation shall be based upon the same factors applied when the assessments were originally established. The property owner seeking segregation of the assessment shall pay all costs to record the segregation as well as an administrative fee to the city based upon a segregation fee schedule to be established by the city from time to time.

b.    By certified mail, sent to the last known address of the all persons identified in the notice and order; or

c.    If the address of all persons identified in the notice and order is unknown, by posting a copy of the notice and order in a conspicuous place at the site of the violation.

B.    Warning Notice as Alternative to Notice and Order.

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. A warning notice is a communication by the director containing recommended actions that may be taken by the person(s) responsible for an apparent violation in order to potentially avoid the issuance of a notice and order.

2.    The warning notice shall include the following information:

a.    The name(s) of the person(s) determined to be responsible for the apparent violation;

b.    The address or legal description of the real property on which the apparent violation exists or has occurred;

c.    A description of the apparent violation, including the specific provision of this chapter which appears to have been violated;

d.    If applicable, a brief description of any activity which is causing the apparent violation to exist or occur;

e.    A description of any recommended corrective action;

f.    A deadline by which corrective action should be completed in order to avoid issuance of a notice and order;

g.    The signature and written name of the city official issuing the warning notice;

h.    The contact information for the city’s designated contact person or office to which questions regarding the warning notice may be directed;

i.    The date of the warning notice.

3.    A warning notice may be amended at any time to correct clerical errors. An amendment made pursuant to this subsection shall not affect the validity or effective date of the original warning notice.

4.    The warning notice shall be served upon the responsible person(s) by one of the following methods:

a.    By personal service;

b.    By certified mail, sent to the last known address of the responsible person(s); or

c.    If the address of the responsible person(s) is unknown, by posting a copy of the warning notice in a conspicuous place at the site of the apparent violation.

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:

a.    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.

b.    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. The director’s decision to grant, deny, or partially grant a request for an alternative corrective action shall be in writing. If the violation is not cured, the director may issue a notice and order as provided in subsection A of this section.

c.    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.

d.    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:

a.    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.

b.    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.

D.    Criteria for Determining Amount of Monetary Penalty.

1.    The director shall evaluate the five criteria listed in this subsection in determining the appropriate amount of monetary penalty to impose for a particular violation of subsection (C)(2)(b) of this section:

a.    Public health risk from the violation;

b.    Environmental damage from the violation;

c.    Willful or knowing violation;

d.    Economic benefit accruing to responsible person(s) from noncompliance; and

e.    Responsiveness of responsible person(s) in correcting violation.

2.    For each penalty criterion described in subsection (D)(1) of this section, the director shall assign a point score between zero and three that reflects the severity of the violation in the context of the criterion. The director may use the following narrative descriptions as guidance in assigning point scores.

a.    Public health risk—Did/does the violation pose a health risk to humans or animals?

(1)    Zero points—There is little or no health risk resulting from the violation.

(2)    One point—A possibility of sickness exists from exposure to the violation.

(3)    Two points—Serious illness is a concern resulting from the violation.

(4)    Three points—Very serious illness and possible long-term health concerns result from the violation.

b.    Environmental damage—Has the condition damaged the environment?

(1)    Zero points—Little or no environmental damage occurred as a result of the violation.

(2)    One point—Minor environmental damage due to the violation can be inferred from the evidence.

(3)    Two points—The environmental damage resulting from the violation requires moderate restoration to be done.

(4)    Three points—The scope of the environmental damage resulting from the violation requires large scale restoration.

c.    Willful or knowing—Is there evidence to support a claim that the violation resulted from a willful or knowing act?

(1)    Zero points—The violation was not due to a willful or knowing act.

(2)    One point—Evidence supports a claim that the violation could be the result of a willful or knowing act.

(3)    Two points—Highly probable that the violation resulted from a willful or knowing act.

(4)    Three points—No question that the violation definitely resulted from a willful or knowing act.

d.    Economic benefit from noncompliance—Did the violation result in an economic benefit to the responsible person(s)?

(1)    Zero points—Little or no economic benefit resulted from the violation.

(2)    One point—There could have been an economic benefit from the violation, but it cannot be determined.

(3)    Two points—There was a direct economic benefit from the violation, but the amount of the benefit could not be determined.

(4)    Three points—A direct economic benefit resulted from the violation, the amount could be approximated and it was significant.

e.    Responsiveness—Is/was the responsible person responsive in correcting the violation?

(1)    Zero points—No advance notice of violation or no deadlines for compliance established.

(2)    One point—Showed good effort to correct the violation when notified.

(3)    Two points—Made minor efforts but did nothing substantial to correct the violation.

(4)    Three points—No attempt made to cooperate or correct the violation.

3.    After assigning point values to each of the criteria set forth in subsection (D)(2) of this section, the director shall sum the point values to obtain the total point value for the violation at issue. Total point value shall be translated into the applicable base penalty amount by reference to subsection (E)(1) of this section.

E.    Monetary Penalty Schedule.

1.    The total point value for the violation at issue obtained from subsection (D)(2) shall be used to determine the appropriate base penalty amount in the chart below:

Total Number of Points

2.    Pursuant to subsection (C)(2)(b) of this section, if the violation is a repeat violation or if the violator is a repeat violator, the applicable base penalty amount listed in the chart above shall be doubled.

3.    Pursuant to subsection (C)(3) of this section, any costs incurred by the city in investigating and enforcing the violation may, at the discretion of the director, be added to the base penalty amount obtained above.

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:

a.    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.

b.    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.

c.    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.

d.    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.

e.    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.

G.    Revised Notice and Order.

1.    Consistent with subsection (C)(3) of this section, a revised notice and order may be issued to the person(s) responsible for a violation for the purpose of adjusting the amount of monetary penalty imposed in the original notice and order to include costs incurred by the city in investigating and enforcing remediation of the violation. A revised notice and order shall clearly reference the original notice and order that is being revised. The issuance of a revised notice and order does not affect the validity or issuance date of the original notice and order.

2.    The recipient(s) of a revised notice and order shall respond to the revised notice and order in one of the following ways:

a.    Pay the Additional Amount of Penalties in a Timely Manner. The recipient(s) of a revised notice and order may pay the increased amount of monetary penalties to the city within the longest of the following time periods: (i) within thirty calendar days of receiving the revised notice and order, (ii) by the deadline specified in the revised notice and order, if any, (iii) by any extended deadline for payment of the original monetary penalty that has been agreed to by the director pursuant to subsection F of this section, or (iv) if the original notice and order was timely appealed, then by the deadline for payment of the original monetary penalty that is specified in the final order resulting from the appeal, as described in subsection I of this section.

b.    Contest the Revised Notice and Order. The recipient(s) of a revised notice and order may contest the accuracy, validity, or appropriateness of the increased amount of monetary penalties imposed by the revised notice and order by appealing the revised notice and order to the hearing examiner within thirty calendar days of receiving the revised notice and order. The scope of such appeal shall be strictly limited to the accuracy, validity, and appropriateness of the increased amount of monetary penalties imposed by the revised 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. All appeal documents shall be delivered to the city clerk by mail, personal delivery or other method, as provided in Section 17.13.090. If an appeal of the original notice and order is pending with the hearing examiner, the hearing examiner shall have discretion to consolidate the appeals.

c.    To the extent applicable, the provisions of subsections H through J of this section shall each apply to a revised notice and order, just as they apply to an original notice and order.

H.    Hearing Examiner Process for Appeal of Notice and Order.

1.    Except as expressly provided to the contrary in this section, the provisions of Chapter 2.38 and any applicable rules adopted by the hearing examiner shall govern the appeal of a notice and order.

2.    Unless an appeal of a notice and order is summarily dismissed by the hearing examiner, the hearing examiner shall hold a public hearing regarding the appeal within sixty business days of the date on which the hearing examiner received the appeal.

3.    The hearing examiner shall issue a decision regarding the notice and order within ten days after the conclusion of the hearing.

4.    Should the appellant(s) of a notice and order fail to appear at the public hearing regarding the notice and order, the hearing examiner shall issue a decision dismissing the appeal. In that event, the notice and order shall become a final determination of the following: (a) that the violation described in the notice and order occurred; (b) that the person(s) identified in the notice and order as being responsible for the violation are the responsible person(s); and (c) that the amount of any monetary penalty set forth in the notice and order is reasonable and affirmed. For good cause shown, the hearing examiner may set aside a decision entered upon an appellant’s failure to appear.

I.    Final Order. A notice and order is considered final if it is not timely appealed. A final order constitutes a conclusive determination that a violation occurred, that the specified person(s) are responsible for the violation, that any monetary penalty imposed is valid and must be paid to the city, and that administrative and judicial options to appeal the determination are exhausted. Unless a different timeline is set forth in the final order or agreed to in writing by the director, the responsible person(s) must comply with a final order within thirty calendar days of the date on which the order becomes final.

J.    Failure to Comply with Final Order.

1.    If the person(s) responsible for a violation under a final order do not fully comply with the final order within the required time period, the city may take any one or more of the following actions to cause the responsible person(s) to comply:

a.    Institute a civil action in any court of competent jurisdiction to enforce the final order, to collect the monetary penalties imposed pursuant to this section, or both;

b.    Abate and remediate the violation in accordance with the provisions of this section and other applicable law and charge the costs of such abatement to the responsible person(s) as additional monetary penalties owing under subsection (C)(3) of this section.

c.    Cause the responsible person(s) to be criminally prosecuted as provided in subsection L of this section; or

d.    Pursue other remedies allowed by law, as outlined in subsection P of this section.

K.    Criminal Prosecution.

1.    As an alternative to any other judicial or administrative remedy provided in this chapter or by law or other ordinance, any person who willfully or knowingly violates this chapter, or rules and regulations adopted thereunder, or any order issued pursuant to this chapter, or by each act of commission or omission procures, aids or abets such violation, is guilty of a misdemeanor and upon conviction shall be punished as provided in Chapter 1.32, as it now exists or is hereafter amended. Each day such violation continues shall be considered an additional misdemeanor offense.

L.    Reduction of Monetary Penalties.

1.    Monetary penalties imposed pursuant to this section may be reduced or waived under the circumstances and in the amounts specified below:

a.    The director shall waive any monetary penalties, or portions thereof, imposed due to mistake or error of the city.

b.    As provided in subsection (F)(1)(a) of this section, the director may partially or fully waive any monetary penalties associated with a violation if the responsible person(s) remediate the violation within the time period specified in the notice and order.

c.    Subsection (F)(1)(b) through (d) of this section provide the director with discretion to conditionally reduce the monetary penalties associated with a violation under specified circumstances. The director shall exercise this discretion based on consideration of the facts and circumstances surrounding the violation at issue, including, but not limited to, the severity of the violation, the magnitude of the public interest being protected, and the willingness of the responsible person(s) to correct the violation once made aware of the violation. If the director determines it is appropriate and fair to reduce the monetary penalties associated with a violation, the director shall also have discretion to determine the amount by which monetary penalties should be reduced.

M.    No City Liability. Administration or enforcement of this section shall not be construed to impose or create a basis for any liability on the part of the city, its appointed or elected officials, officers, agents, or employees, nor shall this chapter be construed to create any special relationship with or otherwise protect any specific person or class of persons.

N.    Immunity from Suit.

1.    Any city appointed or elected officials, officers, agents or employees charged with the administration or enforcement of this section acting in good faith and without malice on behalf of the city shall not be personally liable for any damage that may accrue to persons or property as a result of any act required by the city, or by any reason of any act or omission in the discharge of those duties.

2.    Any suit brought against city appointed or elected officials, officers, agents or employees because of an act or omission performed in the administration or enforcement of any provision of this section shall be defended by the city subject to the provisions of Chapter 2.26.

O.    Compliance with Other Laws. Compliance with this section does not constitute a waiver of the requirements of any other applicable federal, state or local laws and regulations.

P.    Additional Remedies.

1.    Notwithstanding any other provision of this chapter, whenever the director finds that a violation of this chapter, or rules or regulations adopted hereunder, has created or is creating an unsanitary, dangerous or other condition which, in the director’s judgment, constitutes an immediate hazard, the director may suspend or revoke any permit for which the approval of a drainage plan is required on the project or development where the violation exists and suspend or terminate operations under the permit immediately.

2.    The failure or refusal of the city to enforce any provision of this chapter, and as hereafter amended, shall not constitute a waiver or bar to prevent enforcement thereof against any person for a subsequent violation of this chapter, or for any other violation by any other person.
