furnished to be served by the sewer determined in the manner
prescribed in RCW 35.44.030 and 35.44.040 for determining
“assessable units of frontage” shall be multiplied by the average
five-year local improvement assessment per unit of frontage for
lateral sewers for the five-year period in which the property to be
connected was constructed and accepted as completed, as
follows:
Year 1955-59 1960-64 1965-69 1970
Sewer
Rate
$5.26
$8.11
$10.97
$12.00
The lateral sewer charge shall be waived by the City
providing the owner, developer or applicant constructs at his own
expense a sanitary sewer to serve his property, and providing that
the sewer is in compliance with the comprehensive sewage plan
and specifications and requirements of the City. The City shall
also waive the area or trunk sewer charge if the owner, developer
or applicant constructs at his sole expense a sanitary sewer so as
to serve other properties, and is over-sized to accept sewage
generated from other properties, which properties are not
contributing to the construction cost of the over-sizing. The
construction shall be in accordance with the comprehensive
sewage plan and specifications and requirements of the City.

constructed and accepted, as follows:
Year 1955-59 1960-64 1965-69 1970

.0160
.0195
.0200
.0200
Such special connection charge for property abutting on a
street, in which a sewer can be constructed or extended to serve
such property, shall be computed as if the sewer were so
constructed or extended; and the special connection charge for
property located back from the margin of the street in which the
sewer exists and outside of the assessment district created
therefor shall be made giving consideration to the distance of the
property from the street margin. In no case shall credit be allowed
for the cost of extra length of side sewer required for connection
to the City’s sewerage system. Provided, that in cases where
application of the foregoing formula to a particular property results
in a charge which because of unusual conditions is in excess of
charges to similar properties, the Director with express approval
of the City Council is authorized to reduce the special connection
charge to the amount charged to properties similarly situated.

Improvement District fund.
(Ord. 2314 §3 (part), 2010)

sewer stub connection that has been installed, but which was
never assessed nor paid for, shall pay the charge in accordance

system or plan of the storm and surface water utility that report
entitled “City of Tukwila Storm and Surface Water Utility Plan”
dated May 23, 1989, on file with the City Clerk and City engineer
and incorporated in TMC Chapter 14.28 by this reference as
though set forth herein. This original system or plan shall include
all properties, interests, and physical and intangible rights of every
kind or nature owned or held by the City, however acquired, insofar
as they relate to or concern storm or surface water, further
including without limitations all such properties, interests and
rights acquired by adverse possession or by prescription, directly
or through another, in and to the movement, drainage or storage,
or any or all of these, of storm or surface waters, or both, through,
under or over land, landforms, watercourses, sloughs, streams,
ponds, lakes and swamps; all beginning, in each case or instance,
at a point where storm or surface waters first enter the storm or
surface water system of the City and ending in each case or
instance at a point where such storm or surface waters exit from
the storm or surface water system of the City, and in width to the
full extent of inundation caused by storm or flood conditions. Such
plan includes various improvements and betterments of the
existing facilities and extensions thereof as are described therein.

14.28.040 Property Transferred to Utility
The City Council expressly finds that the above-described
system and plan of storm surface water properties, interests and
physical intangible rights transferred to the utility is equal to the
value of release from primary responsibility therefor insofar as it
relates to or concerns storm or surface waters within the City; and
accordingly, all of the above-mentioned facilities for purposes of
RCW 43.09.210 are transferred to and subject to the
administration of the utility created by TMC Chapter 14.28, and all
other institutions and departments of the City having responsibility
therefor are, to the same extent, released from such primary
responsibility.

“storm and surface water utility fund.” All revenues, assessments
and other charges collected by the utility, or otherwise received for
storm and surface water purposes or attributable to the operation
and maintenance of the utility, and all loans to or grants or funds
received for its construction, improvement and operation, shall be
deposited in the storm and surface water utility fund. All
disbursements for costs of planning, construction, acquiring,
maintaining, operating and improving the utility facilities, whether
such facilities are natural, constructed or both, and administering
the utility, shall be made from the storm and surface water utility
fund.
B. The City may create, at such time or times as it deems
appropriate, any other funds necessary to the administration of the
storm and surface water utility, and may designate the revenues
to be placed therein and the purpose or purposes of such funds
which may be the same as one, some or all of the purposes
designated in TMC 14.28.050 as the purposes of the storm and
surface water utility fund created herein, and such purposes shall
then be transferred to such newly created fund.

14.28.070 Limitation of Liability
TMC Chapter 14.28, any storm and surface water code to be
adopted by the City Council to implement TMC Chapter 14.28, and
any guidelines, rules, standards, specifications, requirements,
regulations and procedures established pursuant to any section of
such code are intended to provide the authority and processes to

diagnose the storm and surface water problems of the City, and to
appropriate funds to alter the existing conditions in order to
remedy certain storm and surface water problems as and in the
order that the City determines to be most critical to the health and
safety of the residents of the City as funds become available to
remedy these problems. There shall be no liability associated with
the utility’s approval of any privately constructed portion of the
storm and surface water system and/or privately maintained
portion of the storm and surface water system, unless the City
accepts the same as part of its publicly owned and/or maintained
system.
(Ord. 1523 §7, 1989)
14.28.080 Civil Penalties
A. The violation of or failure to comply with any order or
requirement made in accordance with the provisions of TMC
Chapter 14.28 is a civil violation. The provisions of TMC Chapter
8.45 shall be used to enforce TMC Chapter 14.28.

A. The Director may require from the applicant a surety,
cash bond, irrevocable letter of credit or other means of financial
guarantee acceptable to the City, prior to approving a permit
issued under TMC Chapter 14.30.
B. The amount of the financial guarantee shall not be less
than the total estimated construction cost of all interim and
permanent stormwater control facilities and shall not be fully
released without final inspection and approval of completed work
by the City.
C. For developments that may involve a risk of property
damages or possible hazards, the Public Works Director may
require the provision of financial guarantee (bond, note, letter of
credit, etc.) with the City to mitigate damages should they occur.
The following provisions shall apply in instances where such
financial guarantees are required:
1. Such bond or other proof of financial guarantee shall
not exceed 150% of the estimated cost of constructing and
maintaining those improvements which are the source of the risk
or potential hazard; provided that, in the case of surface water
activities which do not involve expenditures at least equal to the
cost of remedying the possible adverse impacts of such activities,
the required financial guarantee shall be equal to City staff’s best
estimate of the possible cost directly associated with remedying
the adverse impacts to public or private properties not associated
with the development.
2. The amount of any financial guarantee shall not
serve as a gauge or limit to the compensation collected from a
property owner because of damages associated with any surface
water activity.
D. The City shall retain the financial guarantee until the
completion of any project involving surface water activity or
following a prescribed trial maintenance period.
E. The City may redeem financial guarantees provided in
accordance with this provision in whole or in part upon
determination by the Director that any or all of the following
circumstances exist:
1. Failure on the part of the party providing such
financial guarantee to fully comply, within the time specified, with
approved plans and/or any corrective or enforcement actions
mandated by TMC Chapter 14.30; or,

the activities for which the financial guarantee was required.
(Ord. 2675 §20, 2022)
14.30.170 Insurance
A. If, in the opinion of the Director, the risks to property or
life and safety associated with a proposed development activity
are substantial, the Director may require the owner of the storm
drainage system to purchase liability insurance coverage in the
following minimum amounts:
1. Bodily injury liability - $3 million per occurrence.
2. Property damage liability - $3 million per occurrence.
B. The Director may require higher policy limits than set
forth in TMC Section 14.30.170.A in those cases where the
minimum amounts are deemed insufficient to cover possible risks.
C. All insurance policies obtained in accordance with TMC
Section 14.30.170 shall name the City of Tukwila as an “additional
insured,” and shall be written by a company licensed to do
business in the State of Washington. Neither issuance of a permit,
nor compliance with these provisions or any other conditions
imposed by the City relieves any person from responsibility for
damage to persons or property otherwise imposed by law, nor for
damages in an amount greater than the insured amount. Issuance
of a permit shall not form the basis of liability against the City for
damages to persons or property arising from the development
activities permitted by the City or otherwise undertaken by any
person.

The following types of discharges shall not be considered illicit
discharges for the purposes of this chapter if they meet the stated
conditions or unless the Director determines that the type of
discharge, whether singly or in combination with others, is causing
or is likely to cause pollution of surface water or groundwater:
1. Potable water, including water from water line
flushing, hyperchlorinated water line flushing, fire hydrant system
flushing, and pipeline hydrostatic test water. Planned discharges
shall be de-chlorinated to a concentration of 0.1 ppm or less, pH-
adjusted to a level within the range of 6.5 and 8.5, if necessary,
and in volumes and velocities controlled to prevent re-suspension
of sediments in the stormwater system.

Stormwater Pollution Prevention Plan (“SWPPP”) reviewed and
approved by the City that addresses control of such discharges by
applying AKART to prevent contaminants from entering surface or
groundwater.
7. Storm system dye testing is allowable by the City
and dye testing by others requires written notification to the City
with approval from the Director.
(Ord. 2675 §24, 2022)
14.30.210 Best Management Practices
A. Operational Source Control BMPs. All activities with
the potential to release pollutants directly or indirectly to the City’s
stormwater drainage system must be mitigated by Source Control
BMPs to prevent or reduce pollutants in runoff. For all discharges,
property owners or persons in control shall implement operational
Source Control BMPs to prevent or minimize pollutants from
leaving a site or property and to prevent contaminants from
coming in contact with stormwater.
B. Additional BMPs. Property owners or persons in control
of sites with pollutant generating activities shall implement Source
Control BMPs to the extent necessary to prevent prohibited
discharges. If Operational Source Control BMPs are insufficient
to prevent prohibited discharges, the Director may require the
implementation of structural Source Control BMPs or treatment
BMPs in accordance with the SPPM or SWDM.
(Ord. 2675 §25, 2022)
14.30.220 Liability

14.30.230 Enforcement Authority, Procedure, and
Penalties
A. The Director shall have the authority to issue an
enforcement order to an owner or responsible party to abate an
illicit discharge, and/or maintain or repair a component of a
stormwater drainage system in accordance with the provisions of
this chapter. The order shall include:
1 A description of the specific nature, extent, date,
and time of the violation and the damage or potential damage that
reasonably might occur;
2. A notice to cease and desist the violation or the
potential violation and, in appropriate cases, the specific corrective
actions to be taken; and
3. A reasonable time to comply, depending on the
circumstances.
B. The Director may impose an inspection fee for any
stormwater drainage system found not to be in compliance with
this chapter. This inspection fee shall be independent of any
current or future penalties that may be incurred by the property
owner for noncompliance with this chapter. Inspection fees shall
also be applied if the City is required to inspect a stormwater
drainage system because the property owner failed to complete
the required annual inspection. Inspection fees shall be in
accordance with the fee schedule adopted by resolution of the City
Council.
C. If the enforcement order is not adhered to, the City may
provide such actions as needed to repair, restore or maintain the
stormwater drainage system. If at any time the City determines
that the existing system creates any imminent threat to public
health or welfare, the City may take immediate measures to
remedy said threat. Under such circumstances no notice to the
owner of the system shall be required.
D. The owner of the stormwater drainage system shall
assume all responsibility for the cost of any maintenance and for
repairs to the system. Such responsibility shall include
reimbursement to the City within 30 days of the receipt of the
invoice for any work the City performs pursuant to TMC Section
14.30.230.D. Overdue payments will require payment of interest
at the current legal rate for liquidated judgments. If legal action
ensues, any costs or fees incurred by the City will be borne by the
parties responsible for said reimbursements.
E. In the event the property owner fails to pay the City within
30 days from the date the costs were incurred, the City shall have
the right to file a lien against the real property for all charges and
expenses incurred. Such lien shall specify the expenses incurred,
provide a legal description of the premises and will be filed with
the County Auditor within 90 days from the date of the completion
of the work. Payment may at any time thereafter be sought by
foreclosure procedures of liens under the laws of the State of
Washington.
F. Any person who violates or fails to comply with the
requirements of this chapter or who fails to conform with the terms
of an order issued by the Director shall be subject to a civil penalty
as provided in TMC Chapter 8.45. Each day of continued violation
shall constitute a separate violation for purposes of this penalty.
(Ord. 2675 §27, 2022)
14.30.240 Injunctive Relief
A. Whenever the City has reasonable cause to believe that
any person is violating or threatening to violate TMC Chapter
14.30 or any rule or other provision adopted or issued pursuant to
TMC Chapter 14.30, it may either before or after the institution of
any other action or proceeding authorized by TMC Chapter 14.30
institute a civil action in the name of the City for injunctive relief to
restrain the violation or threatened violation. Such action shall be
brought in King County Superior Court.
B. The institution of an action for injunctive relief under TMC
Chapter 14.30 shall not relieve any party to such proceedings from
any penalty prescribed for violations of TMC Chapter 14.30.
(Ord. 2675 §28, 2022)
14.30.250 Appeals
The appeals process for/by any person aggrieved by the
action of the City is provided under TMC Chapter 8.45,

(Ord. 1932 §1 (part), 2000)
14.32.020 Definitions
The following words, when used in TMC Chapter 14.32 shall
have the meaning identified below:
1. “Billing year” means the calendar year in which bills
are sent.
2. “Developed Surface” means those surfaces which
have altered the natural infiltration or runoff patterns that are
characteristic of natural land as it existed prior to development and
are not green and growing, landscaped, or submerged. Such
surfaces shall include hard surfaces that prevent or retard the
entry of water into the soil; to include, but not limited to: roof tops,
asphalt or concrete paving, driveways, parking lots, patio areas,
storage areas, or other compacted surfaces. Such surfaces shall
further include porous surfaces which may accelerate the
infiltration or transfer of surface or ground water; to include, but not
limited to: infiltration pits, piles of rock or quarry spalls, constructed
surface water drainage channels, or similar surfaces.
3. “Natural land” means parcels that have not been
disturbed from their natural state in the last 25 years. 100% of the
parcel must be natural land for the parcel to be classified as natural
land.
4. “Parcel” means the smallest separately segregated
unit or plot of land having an identified owner(s), boundaries, and
area as defined by the King County assessor and recorded in the
King County assessor’s real property file or in the King County
assessor’s maps.
TITLE 14 – WATER AND SEWERS
Produced by the City of Tukwila, City Clerk’s Office Page 14–38
5. “Percent developed surface” means the quotient of
the total area of developed surface on a parcel divided by the total
area of the parcel. For purposes of determining the rate category,
the resulting percentage shall be rounded to the nearest whole
percent.
6. “Undeveloped surface” means any surface area that
is green, growing, or landscaped and supporting vegetation and
shall include land which is totally submerged.
7. “Property owner of record” means the person or
persons recorded by the county assessor to be the owner(s) of
property and/or to whom property tax statements are directed.
8. “Rate category” means the classification of
properties, based upon the estimated percentage of developed
surface on the parcel, for purposes of establishing Utility Service
Charges.
9. “Service charge” means that charge imposed on all
parcels within the City by the storm and surface water utility, and
shall be the rate category to which the parcel is assigned multiplied
times the total area of the parcel rounded to the nearest 4,356
square feet (1/10th of one acre).
10. “Single-family residential parcel” shall mean any
parcel which contains one, two or three single-family units. A
“duplex” is equal to two single-family units. A “triplex” is equal to
three single-family units.
11. “Utility” means the City storm and surface water
management utility.
(Ord. 1932 §1 (part), 2000)
14.32.030 Utility Rates and Service Charges
A. A utility rate and service charge is imposed on every
parcel within the City and the owner(s) thereof. This includes but
is not limited to parcels owned by the City, by the State, by the
County, and all other parcels.
B. The rate category established herein shall be based upon
the contribution of surface and storm water from a parcel to the
system. The amount of contribution to the system shall be
measured by the estimated percentage of developed surface area
on the parcel. The service charge imposed on each parcel shall
be equal to the rate category into which the parcel fits multiplied
times the total area of the parcel rounded to the nearest 4,356
square feet (1/10 of one acre). Single-family residential parcels
are grouped together into one rate category and will pay one
service charge per parcel. This rate category and service charge
is determined by estimating the average developed percent
surface and the average total area of all single-family parcels in
the City.
C. Utility rate categories and annual service charges shall
be charged in accordance with the fee schedule to be adopted by
motion or resolution of the Tukwila City Council.
D. Pursuant to RCW 90.03.525, all parcels within a limited
access highway owned by the State Department of
Transportation shall be subject to service charges that are equal
to 30% of that which would result if the service charges were
calculated according to section 14.32.030C of the Tukwila
Municipal Code.
E. Each annual bill will be rounded up to the nearest number
of cents. The minimum annual service charge shall be equal to
the annual charge for a 4,356 square foot parcel in the lowest rate
category (1, Natural).

14.32.050 Service Charge Adjustments
A. Any person receiving a utility service charge may apply
in writing to the Director of Public Works of the City of Tukwila for
a service charge adjustment. Filing such a request does not
extend the period for payment of the charge. Requests for
adjustments on delinquent accounts will not be acted upon until
paid in full.
B. A request for a billing adjustment may be based on one
or more of the following:
1. The total area of the non-single-family residential
parcel is incorrect;
2. The percent of developed surface on the non-single-
family residential parcel(s) for the billing year for which the service
charge is imposed is incorrect and the actual percent of developed
surface on the parcel places it in a rate category different than that
used for calculation of the service charge;
3. The parcel or portion of it is outside the City and the
service charge is calculated on that portion outside the City;
4. The service charge calculated is erroneous in
applying the terms of this chapter.
C. Application for adjustments may be made to the Director
of Public Works of the City of Tukwila. The burden of proof shall
be on the applicant to show that the rate adjustment sought should
be granted. All decisions of the Director of Public Works shall be
final.

E. The service charge or any part thereof which becomes
delinquent shall bear interest as provided in RCW 35.67.200 at the
rate of 8% per annum, or such rate as may hereafter be authorized
by law, computed on a monthly basis from the date of delinquency
until paid.
F. The City shall have a lien for all delinquent and unpaid
service charges, including interest thereon, against any parcel for
which the service charges are delinquent, as provided by RCW
35.67.200. The current charges imposed by the King County
Records and Elections Division shall be charged to all liened
parcels to recover the cost of placing and removing the lien on the
parcel. Pursuant to RCW 35.67.215, the lien is effective for up to
one year’s delinquent service charges without the necessity of any
writing or recording of the lien with the King County Records and
