Acceptance of a side sewer connection under the provisions of this chapter within or outside of the city’s right-of-way shall not be deemed to create a duty upon the city to repair, maintain, replace, or clean the same.
A permit is required for all work to construct, extend, relay, or repair a building sewer or a side sewer, or to make any connection to a side stub or the public sanitary sewer, whether that work is performed on private property or within the city right-of-way. In addition to any conditions expressed on the permit, all sewer permits are subject to the provisions of this chapter. The director shall be allowed to inspect the work at any stage of construction and, in any event, the applicant for the permit shall notify the director when the work is ready for final inspection, and before any underground portions are covered. Work shall be done by the owner or a licensed contractor as provided for in this chapter.
When a permit has been issued, no additional work outside of the particular work for which the permit was issued shall be completed without the advance approval of the director, and a new permit must be obtained for such additional work.
A. Fees – Generally. The city council shall, by resolution, establish the fees to be assessed to implement and operate the regulations adopted in this chapter. An additional charge will be made if review and inspection time exceeds three and one-half hours. The hourly rate for this additional staff time shall be paid at the rate as established by council resolution. The fee shall be paid to the city before the permit is issued. In the event of any conflict or ambiguity regarding any fees authorized under this chapter and established by council resolution, the director is authorized to interpret the fee schedule(s) to resolve that conflict or ambiguity.
B. Onsite sewage system fees – Public Health. Permits to construct, install, or repair onsite sewage systems are issued by the Department of Public Health – Seattle and King County in accordance with the King County Code. Application for all necessary permits and payment of associated fees shall be made directly to the Department of Public Health – Seattle and King County.
C. Unauthorized work – Penalty. When work is commenced or performed without first obtaining the required permit, the basic permit fee will be doubled; however, the payment of that doubled fee will not relieve the person responsible for the violation from full compliance with all of the requirements of this chapter in the execution, inspection, or approval of the work, or from any other penalties that may be provided for by local, state, or federal law, including criminal penalties.
At the discretion of the director, a temporary permit may be issued permitting temporary connection to a public sanitary sewer, sewer outfall, or side sewer. This temporary permit may be issued when, in the opinion of the director, failure to do so would endanger human health or the environment. A temporary permit is revocable by the director upon providing 60 days’ advance written notice to the owner, occupant, and the permit applicant. This notice shall be given by posting the notice on the premises for which the permit was issued, or by mailing notice to any other address known by the city for the owner, occupant, and applicant. If the private sewer or drain is not disconnected at the expiration of such notice, the director may disconnect the sewer or drain and collect the cost of such disconnection from the owner, occupant, or permit applicant through the issuance of an invoice in accordance with KCC 7.04.270(A). Any permittee granted a temporary permit under this section will hold the city harmless from any damage by reason of the issuance or revocation of a temporary permit, or the disconnection of a temporary connection, as provided for under this section.
Any permit required by this chapter must, at all times during the performance of the work and until completion and final approval thereof, be posted in a conspicuous place at or near the permitted work premises.
Any permit issued under the provisions of this chapter shall be valid for a period of six months. In the event work is not completed within the time specified on the permit, an extension must be requested through the city permit center. Permit extension approvals will be granted on a case-by-case basis. No more than two extensions may be issued, at which time a new permit must be obtained.
A. Permit required. It shall be unlawful for any person to construct, install, or repair any onsite sewage system within the city without first obtaining a permit from the Department of Public Health – Seattle and King County, or any other approval that department may require. That department shall issue permits pursuant to the applicable King County standards, and the permit shall, until all work is completed and final approval obtained, be posted in a conspicuous place at or near the permitted work premises.
B. Disposal of contents. All liquids and solids removed from an onsite sewage system shall be disposed of to the satisfaction of the director and in accordance with all federal, state, and local laws.
All sewers and side sewers shall be installed in strict accordance with the specifications contained in any existing city ordinance or code, any construction standards, any international or uniform codes that the city has adopted or adopts in the future, and any conditions imposed upon an issued permit. All construction shall be subject to the inspection of the director.
A. Proper sanitation required. It shall be unlawful for any person to place, deposit, or permit to be deposited in an unsanitary manner upon public or private property within the city or in any area under the jurisdiction of the city, any human or animal excrement, or other objectionable waste.
B. Sewage disposal system – Chapter compliance required. Except as provided in this chapter, it shall be unlawful to construct or maintain any privy, privy vault, septic tank, cesspool, or other facility intended or used for the disposal of sewage.
C. Connection to public sanitary sewer required. The owners of all houses, buildings, properties or other premises used in any manner for human occupancy situated within or without the city that abut any street, alley, or easement in which there is located a public sanitary sewer of the city shall, at their expense, install suitable toilet facilities therein and connect those facilities directly to the proper public sanitary sewer within 90 days from the date of official notice to do so; provided, that the public sanitary sewer is within 200 feet of any building on the owner’s property.
D. Failure to connect when required. In addition to any other penalty authorized by this chapter, a property owner who fails to connect to the public sanitary sewer within 90 days of receiving official notice to do so may be subject to a penalty that shall be a monetary charge in an amount equal to the base monthly sewer rate that would be charged against that property if it were connected to the public sanitary sewer. The city’s finance department shall assess the penalty against the property through its utility billing system.
E. Lien for costs and charges. Pursuant to RCW 35.67.200, failure to pay the penalties levied pursuant to this section shall constitute a lien for those delinquent and unpaid charges against the premises to which the service is available. This lien shall be superior to all other liens and encumbrances except general taxes and local and special assessments.
F. Interest assessed for delinquencies. All delinquent charges imposed under the authority of this section shall bear interest at the rate of eight percent per annum computed on a monthly basis.
(Ord. No. 4210, § 2, 8-16-16; Ord. 4285 § 2, 2018)
No privy well, vault, or cesspool may be used or maintained if such use or maintenance is detrimental or dangerous to life or health. If such condition exists, the director may prohibit use of the privy well, vault, or cesspool and may order the same to be disinfected and filled with fresh earth. The director will notify in writing the owner and occupant of such premises that the privy well, vault, or cesspool must be disinfected and filled with fresh earth, and a suitable sewage disposal system, either public or private, constructed within a period of 20 days from and after the time when such notice shall be served, or such later date as the director may determine and identify within the notice.

C. Maintain sanitation. All onsite sewage systems shall be operated and maintained in a sanitary manner at the entire and sole expense of the owner and occupant.
D. Repairs required. Whenever, in the judgment of the director or any public health officer, any onsite sewage system shall fail to function properly, or the continued use of such private onsite sewage system will be detrimental to life or health, the director may order such work to be done upon the premises where the onsite sewage system is situated as necessary to restore and insure sanitary conditions upon such premises. In such event, the director will notify in writing the owner and occupant of such premises of the work required under this subsection. Unless otherwise ordered by the Department of Public Health – Seattle and King County, work shall be completed within a period of 180 days from and after the time when such notice shall be served, or such other time period determined appropriate by the director and warranted by the then existing circumstances. The work shall be done in accordance with all federal, state, and local laws.
A. Failure to act – Connection made by city at cost of owner. If any owner or occupant shall fail, neglect, or refuse to connect its premises to the public sanitary sewer within the time specified in any notice provided under this chapter, or shall fail, neglect, or refuse to do the other work specified and ordered to be done as this chapter provides, the director may make such connection or do such work and collect the cost thereof from the owner, occupant, or other person responsible for the violation through the issuance of an invoice in accordance with KCC 7.04.270(A).
B. Cost to become a lien. If unpaid, this cost shall additionally be assessed and become a lien against the premises as authorized by law.
A. Side sewer.
1. Condition likely to cause obstruction – Violation. It is a violation of this chapter for there to exist in any side sewer a visually evident accumulation of FOG of animal, vegetable, mineral, or petroleum origin which, either alone or in combination with other wastes, is reasonably likely to obstruct flow or interfere with the operation or performance of any part of the sanitary sewer system. If the director shall give notice to the person responsible for the violation of such condition and of the corrective action necessary, it is a further violation of this chapter for such person to fail to take such corrective action.
2. Damaged or noncompliant sewer – Notice and repair – Violation. When any side sewer, whether upon private property or upon the city’s right-of-way, is constructed, laid, connected, or repaired and does not comply with the provisions of this chapter or any construction standards or codes that may hereafter be adopted, or where it is determined by the director that a side sewer is obstructed, broken, inadequate, is a menace to health, or is liable to cause damage to public or private property, the director shall give notice to the person responsible for the violation of such condition and the required corrective action. It is a violation of this chapter for such person to fail to take the required corrective action by the date specified in that notice.
B. Private sewer. Whenever any private sewer connected to any public sanitary sewer becomes obstructed, broken, or out of order and the person responsible for the violation fails to repair the same within five days after notification by the director, the director is hereby authorized to remove, reconstruct, replace, alter, or clear the same as required at the expense of the person responsible for the violation, which expense shall be collected through the issuance of an invoice in accordance with KCC 7.04.270(A). When two or more houses or buildings are connected to the same private sewer, the owners, agents, or occupants of such premises shall be jointly and severally liable for any work done at the direction of the director under this section. No permit shall be required for the removal of obstructions from private sewers, provided the sewer pipe is not damaged.

1. FOG removal device required. All FOG generating facilities shall install, operate, and maintain FOG removal devices of an approved type and adequate size to effectively remove polar and nonpolar FOG, sludge, and settled solids from wastewater prior to the wastewater entering the public sanitary sewer. The city understands that there is a cost attributable to installing a FOG removal device. Therefore, all FOG generating facilities operating at a location within the city as of the original adoption date of this section (August 16, 2016) shall install a FOG removal device within 180 days of receiving notification by the city that such a FOG removal device is required, or such greater time period as determined appropriate by the director and warranted by the then-existing circumstances. All FOG generating facilities that open or relocate within the city after the above-referenced adoption date must install, operate, and maintain a FOG removal device in compliance with this chapter prior to commencing operation.
a. Installation of a FOG removal device. All FOG removal devices shall be installed as required by this chapter and shall conform in all respects to the Uniform Plumbing Code or other applicable building codes adopted for application in the city through Chapters 13.01 and 14.01 KCC, including size, type, and installation method, unless otherwise approved by the director. Plans, specifications, and other pertinent information relating to proposed FOG removal devices shall be submitted for the approval of the director. No construction of such facilities shall be commenced until such approvals are obtained in writing. FOG generating facilities are responsible for obtaining a plumbing permit and final inspection approval before the FOG removal device may be put into operation. A FOG removal device shall be installed at locations where they are readily and easily accessible for cleaning, maintenance, and inspection.
b. Maintenance of FOG removal device. All FOG removal devices shall be maintained and operated by the FOG generating facility at its own expense. These FOG removal devices shall be kept in continuous operation at all times, and shall be maintained in accordance with the Uniform Plumbing Code, established BMPs, and other federal, state, and local law.
i. Minimum frequency of maintenance. At a minimum, all FOG removal devices shall be maintained as required by this subsection. However, an increase in the cleaning frequency and additional BMPs may be required to reflect the actual operating conditions of each FOG generating facility.
(A) Grease interceptor. Maintenance of grease interceptors must be scheduled often enough so that polar FOG and settled solids and sludge do not leave the device through its outlet. At a minimum, the grease interceptor must be cleaned when: (i) the volume of FOG and settled sludge and solids constitute 25 percent of the effective liquid volume; or (ii) if the inlet or outlet displays visible buildup or is obstructed with FOG or other debris. In no event shall the maintenance frequency be less than once every six months.
(B) Grease trap. Maintenance of grease traps must be scheduled often enough so that FOG and settled solids and sludge do not leave the device through its outlet. At a minimum, grease traps shall be cleaned when: (i) the volume of FOG and settled sludge and solids constitute 25 percent of the effective liquid volume; or (ii) if the inlet, outlet, flow control, or vent displays visible buildup or is obstructed with FOG or other debris. In no event shall the maintenance frequency be less than once every month. Unless specifically required or permitted by the city, no food waste disposal unit or dishwasher shall be connected to or discharge into any grease trap.
(C) Oil/water separator. Oil/water separators shall be cleaned when the buildup is eight inches deep in the inlet chamber or when there are two inches or more of oil in any chamber of the oil/water separator. Coalescing plates must be cleaned before they become coated with silt or solids.
ii. Performance of maintenance. Cleaning, inspection, and maintenance must be performed by a licensed contractor and/or wastehauler qualified to perform such activities on a FOG removal device.
(A) Required maintenance for grease interceptors and oil/water separators. Maintenance for grease interceptors and oil/water separators shall include without limitation the removal of the full contents of the grease interceptor and oil/water separator including polar and nonpolar FOG, liquids, and settled sludge and solids from the device’s walls, baffles, inlet, outlet tee, piping, and floors. During maintenance, grease interceptors and oil/water separators shall be inspected for internal and external damage, obstructions, leaks, and missing or damaged components. It is a violation of this chapter to merely skim the surface layer of waste material, to only partially clean the grease interceptor or oil/water separator, or to use any method that does not remove the entire contents of the grease interceptor or oil/water separator. The grease interceptor and oil/water separator shall be filled with clean cold water before returning to service. If cleaning and repairs are required, they shall be performed within seven days of discovery.
(B) Required maintenance for grease traps. Maintenance for grease traps shall include without limitation the removal of the full contents of the device including FOG, liquids, and settled sludge and solids. Removable baffles, plugs, and outlets shall be removed and cleaned, and the walls, cleanout, and all other components of the device shall be scraped free of accumulated FOG and food waste. During maintenance, the device shall be inspected for leaking seams and pipes; damaged or missing gaskets, lids, bolts, and latches; corrosion; and for effective operation of the baffles, venting, and flow-regulating device. The grease trap shall be filled with cold clean water before it is returned to service. If cleaning and repairs are required, they shall be performed within seven days of discovery.
iii. Disposal of material removed during maintenance. All FOG removed from a FOG generating facility shall be disposed of or recycled in accordance with federal, state, and local laws.
iv. Maintenance records. Records of all maintenance activities shall be retained after each maintenance event and shall be made readily available to the city for review via email or in person.
2. Industrial wastes – Control manhole – When required. Any business, establishment, or person who uses the sanitary sewer system to carry industrial wastes shall install and properly maintain a suitable control manhole in the premises’ sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole shall be installed at a location where it is readily accessible, safe, and constructed in accordance with plans approved by the director. The control manhole shall be installed by the owner at the owner’s expense, and maintained by the owner so as to be safe and accessible at all times.
3. Waste cooking oil – Collection and proper disposal. Waste cooking oil shall be collected and stored in appropriate receptacles such as drums or bins at all FOG generating facilities and then disposed of or recycled in accordance with all federal, state, and local laws. Such storage receptacles shall be maintained by implementing proper BMPs to ensure they are watertight and do not leak.
4. Vegetable and fruit canneries – Collection and proper waste disposal. Vegetable and fruit canneries shall provide an efficient screen for the removal of skins, seeds, pomace, culls, discarded produce, and other suspended material and waste from the washing, sorting, or other canning processes. This screen must be 20-mesh, U.S. standard gauge, and may be of the vibrating, rotary, or any other effective type. It shall be located on the main outlet sewer line or lines from the cannery in such a way that all wastewaters, except cooling or other clean waters, will pass through the screen. Cooling or other clean waters may be bypassed around the screen or discharged through a separate outlet. Screened and other solid material removed from the product during cannery operations shall be disposed of in a manner consistent with state solid waste handling regulations, and, in any event, in such a manner that it will not enter a water of the state or the sanitary sewer system.
5. Standard applicable and measurement location. All measurements, tests, and analysis of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with standard methods for the examination of water and sewage, available online at www.standardmethods.org, and shall be determined at the location of the control manhole required under subsection (C)(2) of this section and based upon suitable samples taken from that location. If no control manhole has been required under subsection (C)(2) of this section, the control manhole shall be considered to be the nearest downstream manhole in the sanitary sewer system at the point at which the building sewer is connected to the public sanitary sewer.
No person shall cause to break, damage, destroy, uncover, deface, or tamper with any structure, appurtenance, or equipment which is a part of the sewage works.
It shall be unlawful to plant poplar, cottonwood, soft maples, willow, or any other tree or shrub in any location where the roots of such tree or shrub are likely to obstruct or damage public or private sewers. The director is hereby authorized to remove any trees or shrubs from any public street, or the roots of any trees or shrubs which extend into any public street or right-of-way, when such trees or the roots thereof are obstructing, or when the director has determined that they are liable to obstruct, public or private sewers. The director shall give 10 days’ advance written notice to the owner, agent, or occupant of the abutting property to remove such trees or roots, and it is a violation of this chapter for such owner, agent, or occupant to fail to timely and properly comply with the director’s notice.
If the owner, agent, or occupant fails or refuses to comply with the director’s notice, the director may remove the trees or roots when the city’s access to the property is legally authorized, and the reasonable cost of such removal, whether that removal is from private property, rights-of-way, alleys, or streets, shall be a charge against and a lien upon the abutting property from which such trees or shrubs are removed, which may additionally be collected against the abutting property owner in accordance with KCC 7.04.270.
A. No permits shall issue for connection to any public sanitary sewer for any property that has not been assessed for the construction of such sewer by a local improvement district, except as follows:
1. Property that was not assessed for a local improvement district, but which has a public sanitary sewer in the street, alley, or sewer easement abutting such property shall be charged an assessment on the same basis as property that was in the local improvement district.
2. Satisfactory arrangement shall be made with the finance director for payment prior to the issuing of any permits provided for in subsection (A)(1) of this section.
B. Side sewers constructed without the payment of the above charges shall be disconnected if, within 15 days after the owner and occupant have been notified by the director that the above charges are due, the owner or occupant fail to pay such charges.
7.04.220 Schedule of charges for service.1
King County imposes a sanitary sewer service charge for regional sewage treatment. These charges are passed through, without increase, directly to the city sanitary sewer utility customers. The King County pass-through charge for 2017 is known and established. It is expected, however, that King County will increase its pass-through charge over time. Accordingly, except for the 2017 charge, all other King County charges are estimates only. In order to simplify the rate-making structure, the finance director is authorized to amend King County’s pass-through charges at the time King County imposes new charges.
Beginning January 1, 2018, and on the first day of each calendar year thereafter, the total sewer rate will adjust by the Consumer Price Index (CPI), specifically the CPI-W Seattle-Tacoma-Bremerton, measured from June 1st through June 1st of the previous calendar year, if the CPI-W reflects an upward adjustment from the previous annual June to June period. For the years 2018-2022 the adjustment will not exceed 2.4 percent of the total sewer rate, but after that, beginning January 1, 2023, any increase in the CPI will not be subject to this 2.4 percent limit. In order to simplify the rate-making structure, the finance director is authorized to amend the rate each year to reflect the CPI adjustment.
In addition, the year 2017 city rate for all types of service is subject to any CPI or King County rate increases; for the year 2018 the city rate will increase $1.25 in addition to any CPI or King County rate increases; and for the year 2019 the city rate will increase $0.50 in addition to any CPI or King County rate increases.
The following sanitary sewer service charges for city sanitary sewer service inside the city limits are in effect on the dates and in the amounts listed below. Sewer service charges for customers residing outside the city shall be the charges as on file in the city clerk’s office.
City Sewer Rate
King County Sewer Rate†
Total Sewer Rate
1. Single-family residential dwelling, as defined in Chapter 15.02 KCC.
2. Two-family or multiple-family residential dwelling, as defined in Chapter 15.02 KCC, each unit separately metered and charged.
3. Single-family residential/lifeline: eligibility criteria for the lifeline utility rate set forth in KCC 7.01.080.
4. All other than service types 1, 2 and 3 shall be billed in accordance with the consumption of water and at the following rate,* except that no monthly bill shall be less than the single-family residential rate set forth in service type No. 1.
$8.85* per 100 cubic feet per month
† Estimated, based on adjustments issued by King County.
* Beginning January 1, 2018, this rate will adjust annually based on the basic rate shown for service types 1 and 2 above, calculated on this formula: Total Sewer Rate/7.5 = price per 100 cubic ft. per month.
(Ord. No. 4210, § 2, 8-16-16; Ord. No. 4213, § 5, 8-16-16)
All sewer accounts for other than single-family residential uses must have water meters or sewer meters for billing purposes.
The amount of flow for the purpose of sewer service billing may be measured by a sewer meter installed and maintained at the customer’s expense or by reading a water meter with allowance made for water measured by any exemption meter which has been approved by both METRO and the city.
All sewer meters shall be certified for accuracy at least once each year by an independent testing agency. If the city demands an inspection other than a regular annual inspection and the inspection reveals that the meter is operating properly, the city shall bear the cost of the inspection; otherwise, the cost shall be borne by the customer.
For sanitary sewer service to customers obtaining water from sources other than the city water utility, the following regulations shall apply:
1. Single-family residential customers shall pay the flat rate which is on file in the city clerk’s office.
2. All customers other than single-family residential shall install a meter on their source of water within 30 days of date of application or service will be discontinued. Upon request of the customer, the city will install a meter in accordance with its standard practice for such installations.
3. City personnel will read the privately owned meters on normal water meter reading dates.
4. If the meter is the property of a water district or other municipal corporation, the customer must submit written permission from the water district or municipal corporation for the city meter reader to read such meter on the normal reading date.
A. Recovery of costs incurred by the city. In addition to any penalty provided for in subsections (B) through (D) of this section, a person who violates any of the provisions of this chapter shall be liable for all costs incurred by the city as a result of the violation. The city will issue an invoice to the person responsible for the violation advising him or her of the amount of costs incurred by the city as a result of the violation. The person to whom the invoice was directed must respond within 14 days of the date the invoice is served upon that person by: (1) paying the invoice, (2) requesting a hearing before the city’s hearing examiner to mitigate the amount of the invoice, or (3) requesting a hearing before the city’s hearing examiner to contest the amount of the invoice. Failure to timely respond shall result in the invoice being deemed valid and the city may seek collection of the invoice through the process provided for in Chapter 3.10 KCC, including the use of a collection agency. Payment of any invoice issued shall not alleviate the person responsible for the violation from complying with this chapter.
1. Service of notice. Service of an invoice issued under this subsection (A) shall occur and is deemed complete in the same manner and under the same provisions as provided for in KCC 1.04.060.
2. Process to mitigate or contest invoice. The process through which a person may request a hearing to contest or mitigate an invoice issued to him or her as a person responsible for the violation is the same as that provided for notices of violation under KCC 1.04.120 through 1.04.190. The hearing examiner’s decision as to any invoice issued under this subsection (A) is final and may not be further appealed.
3. Failure to pay – Civil infraction. The failure to timely pay an invoice issued under this subsection (A), or any mitigated invoice amount set by the hearing examiner, is a separate violation that may be enforced through the issuance of a civil infraction pursuant to subsection (B) of this section.
B. Civil infraction. A person who violates any provision of this chapter may be issued a class 1 civil infraction as set forth in RCW 7.80.120, as currently enacted or hereafter amended. An infraction issued pursuant to this section shall be filed in the Kent Municipal Court and processed in the same manner as other infractions filed in the Kent Municipal Court. In addition, a civil code enforcement action may be instituted in accordance with subsection (C) of this section to effectuate any abatement or corrective action required by the person as a result of the violation.
C. Civil code enforcement. In addition to, or as an alternative to any other penalty provided for in this chapter or by law, a civil code enforcement action may be instituted under the provisions provided for in Chapter 1.04 KCC to effectuate any abatement or corrective action required as a result of a violation of this chapter, including the issuance of a stop use or stop work order under KCC 1.04.090 through 1.04.110. The process through which the person responsible for the violation may contest a stop use or stop work order is the same as that provided for notices of violation under KCC 1.04.120 through 1.04.190. Failure to timely abate the violation or take the required corrective action will result in the issuance of a fine in accordance with KCC 1.04.080 and 1.04.200, which fine will be separate and apart from any fine that may have been issued under subsection (B) of this section.
D. Criminal offense. Except as may otherwise be provided, a person who:
1. Negligently violates a provision of this chapter is guilty of a misdemeanor, punishable by up to the maximum penalty established in RCW 9A.20.021(3) as now enacted or hereafter amended; or who
2. Knowingly violates a provision of this chapter, or commits a repeated violation of this chapter, is guilty of a gross misdemeanor, punishable by up to the maximum penalty established in RCW 9A.20.021(2), as now enacted or hereafter amended.
a. For purposes of this section repeated violation means, as evidenced by either a prior committed finding by the Kent Municipal Court of an infraction issued under this chapter, or a committed finding by the hearing examiner of a notice of violation issued under Chapter 1.04 KCC, or a committed finding by operation of law under KCC 1.04.130, that a violation of this chapter has occurred on the same property or that a person responsible for the violation has committed a violation of this chapter elsewhere within the city of Kent. To constitute a “repeat violation,” the violation need not be the same violation as the prior violation.
3. If a person is found guilty of a criminal offense as provided for in this subsection (D), or pleads guilty to another offense on recommendation of the prosecutor, the court shall order the defendant pay restitution to the city of Kent, or any other victim of the offense, for the total suffered loss or damage by reason of the commission of the crime.
Code reviser’s note: Section 8 of Ord. 4213 provides: “Although the fees, rates, and charges established by this ordinance do not take effect until January 1, 2017, this ordinance shall take effect and be in force 30 days from and after its passage, as provided by law.”
