E05 -020, City of Tukwila Sewer System Comprehensive Plan (Area Served
by Tukwila Sewer)
Project Description:
This SEPA review is a non - project action for the 2005 City of Tukwila Sewer System
Comprehensive Plan Update. The proposed Plan provides the basis for sewer service within
Tukwila. The proposal provides an analysis of future needs and methods of implementation
for all sewer users within Tukwila.
The plan includes description and analysis of the following:
• Description of the Sanitary Sewer System
• Related Plans, Policies and Agreements
• Planning Criteria.
• Sanitary Sewer System Design Criteria
• Wastewater Collection System Evaluation
• Operations and Maintenance
• Capital Improvement Plan
• Financial Plan

Summary of Primary Impacts:
As this is a non - project action, no specific impacts are addressed under the 16 elements
normally reviewed in the SEPA checklist. The result of adopting the plan will be
continued provision of sewer service to Tukwila customers. In the Plan, Tukwila proposes
to serve several areas which are currently within the service areas of other
surrounding sewerage entities. The specifics of any proposed transfer of service area will
need to be determined on a case -by -case basis. Tukwila would first obtain an interlocal
agreement from the jurisdiction prior to serving that portion of its territory
Site - specific projects that are implemented after the Plan's adoption may require SEPA
review of related impacts. Any proposed CIP projects will improve the reliability of
Tukwila's sewer system.

Mr. David A. Nunnallee, P.E.
Department of Ecology
3190 160th Avenue SE
Bellevue, WA 98008 -5452
Subject: Comments to 2005 Final Draft Sewer System Plan Update November 2005
Dear Mr. Nunnallee:
This letter addresses the State of Washington Department of Ecology concerns to the 2005
Sewer System Plan Update item by item.
1. Page 2 -2: Existing & Potential Sewer System Map:
The Tukwila service area map appears to show that the City of Tukwila is proposing to
serve several areas which are currently within the service areas of other surrounding
sewerage entities. As some of the surrounding entities have approved comprehensive
sewer plans of their own, it is important to indicate how jurisdictional and boundary issues
will be addressed. We cannot approve a service area for Tukwila if another jurisdiction is
already approved to serve the same area, unless there is some interlocal agreement to
accommodate such an arrangement. According to the map it appears there may be service
area overlap issues with Val Vue SD, City of Kent, City of Renton and perhaps a small
corner of City of Des Moines. Additionally the "South Annex" area extends beyond the
Tukwila City limits (unincorporated King County?) and jurisdictional issues there also need
to be described.
Exhibit 2 -1 is drawn at a very large scale and shows very little detail. If the City of
Tukwila were to serve areas of the City serviced by other sewer districts or cities, the
City of Tukwila would first obtain an interlocal agreement from the jurisdiction prior
to the City of Tukwila serving that portion of our City.
2. Section 5 Design Criteria; part 5.3.2 Installation:
Ecology's "Criteria for Sewage Works Design" requires manholes to be spaced no more
than 400 feet apart for sewers 15" diameter or smaller. They can be spaced 500 ft apart
for larger sewers. An exception can be made if the City can demonstrate that they have
sewer cleaning equipment capable of cleaning smaller sewers spaced at 500 ft.
The Public Works Maintenance Department has a vactor truck equipped with 600 feet
of hose to jet sewer and storm lines.

February 1, 2006
3. Section 5 Design Criteria; part 5.5.3 Wet Wells:
It is not clear why pump station wet wells should "provide a holding time not to exceed 10
minutes for the design average flow." Ecology's Criteria for Sewage Works Design
recommends, by contrast, that a minimum of one hour storage at peak flows be provided in
pump station wet wells to prevent sewage overflows.
None of the City of Tukwila's 8 existing Lift Stations have one hour of peak flow
storage in their wet wells. The City of Tukwila provides back -up diesel power to 4 of
the 8 Lift Stations, which serves the commercial areas of the City. All the Lift
Stations are equipped with SCADA systems which monitor functions of the Lift
Stations and notifies staff of any problems via cell phones to prevent overflows.
4. Section 6, Wastewater Collection System Evaluation:
The infiltration/inflow (I /I) evaluation in the report was apparently conducted only to
assure that sewer lines are adequately sized to transport the City's sewage without resulting
in overflows. While this is important, there should be some further evaluation to determine
whether I/I is present in "excessive" amounts, per EPA criteria. A detailed I/I analysis is
not expected at this stage, but an evaluation of at least total City flows would be
appropriate and would help the City to determine whether they need to be planning for I/I
reduction in the future.
The City. of Tukwila has an aggressive I &I program. Every 4 years the City
videotapes sanitary sewer lines looking for leaks and piping problems. In the Capital
Improvement Program, the City commits $30,000 to repair pipes and leaks found
during videotaping. The City sewers are made of PVC, ductile iron, and gasketed
concrete pipe with no combined sewer. The system has very little I &I problems. The
City also participates with King County in their I &I program.
Please contact me at (206)431 -2441 if you have any other questions.

SUBJECT: REVIEW OF CITY OF TUKWILA'S 2005 DRAFT SEWER SYSTEM
PLAN UPDATE
Dear Mike:
The City of Renton has reviewed your draft plan. First, we note that Tukwila does not provide
sanitary sewer service within any portion of Renton's corporate city limits, and, as such, we do
not need to comment on land use or zoning issues related to sewer service. The City of Renton
does provide sanitary sewer service to a small portion within Tukwila's corporate city limits in an
area you have described.as SE City Corner.
• In Chapter 2, you reference the.SE City Corner as part of Drainage Basin No 11: :Tukwila is •
recommending that for study purposes, they will assume this portion of the service area from -
Renton. While we have no objection to.Tukwila considering this from a planning standpoint, we
do request that you add language to this section recognizing the need to negotiate any transfer of
service in this area with the City of Renton.
Thank you for the 'opportunity .to comment on your plan. As it is a well prepared document,
Renton has but the one comment. If you have any questions, please contact me at 425.430.7212.

10. Give brief, complete description of your proposal, including the proposed uses and
the size of the project and site. There are several questions later in this checklist that
ask you to describe certain aspects Of your proposal. You do not need to repeat those
answers on this page.
The City of Tukwila was incorporated in 1908 and, through a series of major annexations,
has increased from 418 acres to 5,176 acres. At the time of a 1989 annexation of the
neighborhoods known as Riverton, Foster, Thorndyke', and Cascade View, sewer service
was provided by the City of Seattle, Val -Vue Sewer District, Rainier Vista Sewer District,
Metro and the City of Tukwila itself.
In 1995 and 1996, respectively, the City of Seattle transferred sewer facilities in the East
Marginal Way corridor and Ryan Hill service areas to the City. In 1997 the City of
Tukwila constructed sewers in the previously unsewered areas of Allentown. The Boeing
Field area was also incorporated into the City's system. Sewer service extension to Foster
Point and some of the Foster neighborhood is anticipated in 2006. Some of the annexed 1
areas that were previously served by other sewer service providers continue to be served
through the original providers — currently, only the City of Renton and Val -Vue Sewer
District continue to provide service within the City of Tukwila boundary. Sewer service
has been extended to many of the unsewered or partially sewered areas since the mid -
1990s.
Between 1961 and 1991, the City's sewer system expanded rapidly through the creation of
Local Improvement Districts (LIDs),. developer extension: agreements and the annexations
that took place in 1989. By 1991, the system included over. 140,000 lineal feet of sewer..
pipe in varying sizes, 470 manholes and eight lift stations. Since that time, approximately
43,000 lineal feet of pipeline, 260 manholes: and one lift station have been added to the _
system.
Sewage from Tukwila is conveyed to, and treated at, the King County/Metro (Metro)
wastewater treatment plant in Renton under an agreement between the City and Metro.
The objective of the 2005 SSP Update is to evaluate the existing sewer system and its
operation to:
• Identify present and future needs in those areas of the sewer system deemed to be
critical by the City,
Set forth the means for addressing those needs, and
• Demonstrate that the system has the operational, technical, managerial, and
financial capability to achieve and maintain compliance with all relevant local,
state, and federal plans and regulations.
The 2005 SSP Update is a Non - Project Action. Specific Capital Improvement Program
(CIPs) projects cited in the SSP will have a separate State Environmental Policy Act
(SEPA) review, where necessary.

The City of Tukwila is bounded by the City of SeaTac on the west, the City of Seattle on
the north, the City of Renton on the east, and the City of Kenton the south. Tukwila's
current and future service area, city boundary, and other adjacent purveyor service areas
are shown in Exhibit 2 -1 of 2005 SSP Update.
In the future, the City expects to add four new areas to its service area. The-precise timing.
of adding these new service areas is dependent on a variety of factors and is not fully`
known. The four new areas include: Ryan Area Septic, SE City Corner, South Septic, and
South Annex.
12. Does the proposal lie within an area, designated on the City's Comprehensive Land
Use Policy Plan Map as environmentally sensitive?
Yes. However, as noted above, approval of the 2005 SSP Update is a;Non- Project Action.

D. SUPPLEMENTAL SHEET FOR NON - PROJECT PROPOSALS
(do not use this sheet for project actions)
Because these questions are very general, it may be helpful to read them in
conjunction with the list of elements of the environment.
When answering these questions, be aware, of the .extent the proposal, or the types of
activities likely to result from the proposal, would affect the itemat a greater
intensity or at a faster rate than if the proposal were not implemented. Respond
briefly and in general terms.
The proposed action is the approval of the City of Tukwila's 2005 SSP Update: ° The 2005
SSP Update refers to the development and utilization of sewer system projects that either.
are, or may become components of the Tukwila sewer system. Environmental impacts
would be associated with the construction;maintenance, and operation of those specific
projects. Those impacts 'either have been or will be evaluated during the'environmental
review of the specific projects. The following paragraphs discuss potential impacts in a
very general manner.
1. How would the proposals be likely to increase discharge to water; emissions to air;
production, storage, or release of toxic or hazardous substances; or production of
noise?
The construction of some of the proposed components of the City of Tukwila's sewer
system may involve the creation and discharge of construction stormwater. Effects on
surface waters during construction could include increased runoff volumes and increased
peak flows.
Impacts to air quality due to the construction of sewer system facilities could include
temporary increases in particulate emissions that would depend on the level and type of
activity, soil characteristics, weather, and equipment employed; increased exhaust from
construction equipment powered by gasoline and diesel engines; increases in emissions
due to delays while transiting through the work areas; and fugitive dust.
Some risk of spills/leakage from equipment will exist during construction.-,Normal
precautions will be taken in storing equipment, hazardous fuels, and other materials used in
construction of the CIP projects.
Construction of the proposed CIP projects will generate short-term noise impacts caused
primarily by equipment operation (i.e. trucks, trenching, and backhoes, etc.) associated
with excavation, material removal, backfilling, minor demolition, and related activities.
Proposed measures to avoid or reduce such increases are:
Minimization of impacts to surface waters would be achieved through implementation of
applicable Best Management Practices (BMPs) and compliance with regulatory
requirements and permit conditions (e.g. NPDES Construction Stormwater Permit, if
applicable).
Minimization of impacts to air quality would be achieved by such measures as keeping
exposed soils damp by spraying with water, covering truck loads, using wheel washers,

and routing of construction truck traffic to help eliminate or reduce delays encountered by
local traffic. Such mitigation and coordination are usually facilitated by the local .
jurisdiction through traffic management and mitigation plans, haul road agreements, and
other permitting requirements.
To protect against hazardous substance. spills from routine equipment operation and
maintenance activities during construction, the contractor would be required to provide an
emergency response plan and know proper hazardous maten41s storage, handling, and
emergency procedures, including proper spill notification response requirements.
Because construction noise will be variable and short term, contractors would implement
measures to minimize disruption and inconvenience caused by construction activities, such
as: minimize idling time of equipment, operate equipment only during-hours approved by
the City of Tukwila, and, ensure the adequacy of mufflers on all engines.
2. How would the proposal be likely to affect plants, animals, fish, or marine life?
Proposed sewer system components would not affect marine life. However, plants,
animals, or fish could be affected by certain facilities depending on their location and
function. Because most of the proposed improvements are buried pipelines, the impacts
would be temporary and limited to.the construction period:
Proposed measures to protect or conserve plants, animals, fish, or marine life are:
The construction of system components would emphasize avoidance of impacts to plants,
animals, and fish. Where complete avoidance is not possible, the principle of minimization
would be stressed. Impacts would bemitigated and-enhancement measures implemented,
as appropriate. Generally, these protective provisions are set forth in land use codes, laws
and regulations, and permit conditions.
3. How would the proposal be likely to deplete energy or natural resources?
Sewer system components would consume, but not deplete, energy and natural resources.
Proposed measures to protect or conserve energy and natural resources are:
System components would be sited, designed, constructed, maintained and operated to be
as efficient as possible.
4. How would the proposal be likely to use or affect environmentally sensitive areas or
areas designated (or eligible or under study) for governmental protection; such as
parks, wilderness, wild and scenic rivers, threatened or endangered species habitats,
historic or cultural sites, wetlands, floodplains, or prime farmlands?
None of the sewer system components are, or would be, located on prime farmlands, near
wild and scenic rivers, or in wilderness areas. It is possible that some of the components
could be located near, on, or traverse environmentally sensitive areas (e.g., wetlands,
streams, or floodplains). However, most of the CIP projects are replacements or new

sewerlines located within existing roadways. Endangered species habitat and historic or
cultural sites would be avoided, whenever possible.
Proposed measures to protect such resources or'to avoid or reduce impacts are:
System components would be sited with the intent of avoiding all environmentally.sensitive
areas. If impacts to an environmentally sensitive area were necessary; the footprint and
construction impacts of the component would be minimized.
5. How would the proposal be likely to affect land and shoreline use, including whether
it would allow or encourage land or shoreline uses, incompatible with existing: plans?
The sewer system components would neither affect land'and shoreline use nor allow or
encourage land or shoreline uses incompatible with existing plans.
Proposed measures to avoid or reduce shoreline and land` use impacts are
System components would comply with existing land use and shoreline management plans.
The majority of the system consists of underground pipelines that are or would be:located
in existing rights -of -way. When a pipeline alignment requires passing through or in the
vicinity of a shoreline, measures would be implemented to minimize construction impacts
and to ensure proper restoration of the affected areas.
6. How would the proposal be likely to increase demands o n transportation or public
service and utilities?
The proposed CIP projects will provide improved reliability to the City of Tukwila's sewer
system. The construction, maintenance, and operation of sewer system components
identified in the 2005 SSP, Update would, to varying degrees depending on the specific
facility and location, impact other utilities. No increased demands on transportation or
public services are anticipated.
Proposed measures to reduce or respond to such demand(s) are:
The City will coordinate with local utilities regarding impacts to their facilities from
construction of the CIP projects.
7. Identify, if possible, whether the proposal may conflict with Local, State, or Federal
laws or requirements for the protection of the environment.
The CIP projects identified in the 2005 SSP Update do not and will not conflict with local,
state, or federal laws or requirements for the protection of the environment.

of Metropolitan Seattle, a metropolitan municipal
corporation of the -State of Washington (hereinafter referred
to as "Metro ");
WITNESSETH:
WHEREAS, the parties have entered into a long term
Agreementifor Sewage Disposal dated October 1, 1966
(hereinafter referred to as the "Basic Agreement "); and
WHEREAS, an advisory committee composed of elected
and appointed officials in the metropolitan area was
appointed by the Metropolitan Council to examine the
structure of Metro's charges to its participants; and
WHEREAS, said advisory_ committee, following
extensive research, study and deliberations, has recommended
certain changes in the structure of Metro's charges to its
participants and implementation of said changes requires
amendment of the Basic Agreement;'and
WHEREAS, the parties have determined that the
recommendations are in the best public interest and
therefore desire to amend said Basic Agreement to implement
said recommendations;
1
NOW, THEREFORE, it is hereby agreed as follows:
Section 1. Amendment of Section 5 of the Basic
Agreement. Section 5 of the Basic Agreement is hereby
amended to read as follows:
"Section 5. Payment for Sewage Disposal. For the
disposal of sewage hereafter collected by the City and
delivered to Metro the City shall pay to Metro on or before
the last. day of each month during the term of this -
Agreement, a sewage disposal charge determined as provided
in this Section 5.-
1. For the quarterly periods ending March 31,
June 30, September 30 and.December;31 of each'year every
Participant shall submit a written report to Metro setting
forth:
(a) the number of Residential Customers billed by
such Participant for local sewerage charges as of the last
day of the quarter,
(b). the total number of all customers billed for
local sewerage charges by such-Participant as of such day,
and
(c) the total water consumption during such
quarter for all customers billed for local sewerage charges
by such Participant other than Residential Customers.
The quarterly water consumption report shall be
taken from water meter records and may be adjusted to
exclude water which does not enter the sanitary facilities
of the customer. Where actual sewage flow from an
individual customer is metered, the metered sewage flows
shall be reported in lieu of adjusted water consumption.
The total quarterly.water consumption report in cubic feet
shall be divided by. 2,250. to determine the number of
Residential Customer equivalents represented by each
Participant's customers other than single family residences.
Metro shall maintain a permanent record of the quarterly
customer reports from each Participant.
The City's first quarterly report shall cover the
first quarterly period following the date when sewage is
first delivered to Metro and shall be submitted within
thirty days following the end of the quarter. Succeeding
reports shall be made for each quarterly period thereafter
and shall be submitted within thirty (30) days following the
end of the quarter.
2. (a) To form a basis for determining the
monthly sewage disposal charge to be paid by each
Participant during any particular quarterly period, Metro
shall ascertain the number of Residential Customers and
Residential Customer equivalents of each Participant. This
determination shall be made by taking the sum of the actual
number of Residential customers reported as of the last day
of the next to the last preceding quarter and the average
number of Residential Customer Equivalents per quarter
reported for the four quarters ending with said next to the
last preceding quarter, adjusted for each Participant to
eliminate any Residential Customers or Residential Customer
equivalents whose sewage is delivered to a governmental
agency other than Metro or other than a Participant for
disposal outside of the Metropolitan Area.
(b) For the initial period until the City shall
have submitted six consecutive quarterly reports, the
reported number of Residential Customers and Residential
Customer equivalents of the City shall be determined as
provided in this subparagraph (b). On or before the tenth
day of each month beginning with the month prior to the
month in which sewage from the City is first delivered to
Metro, the City shall submit a written statement of the
number of Residential Customers and Residential Customer
equivalents estimated to be billed by the City during the
3
•
next succeeding month. For the purpose of determining the
basic reported number of Residential Customers and
Residential Customer equivalents of the City for such next
succeeding month, Metro may at its discretion adopt either
such estimate or the actual number of Residential Customers
and Residential Customer equivalents reported by the City as
of the last day of the next to the last preceding reported
quarter. After the City shall have furnished six
consecutive quarterly reports the reported number of
Residential Customers and Residential Customer equivalents
of the City shall be determined as provided in the
immediately preceding subparagraph (a).
(c) If the City shall fail to submit the required
monthly and /or quarterly reports when due, Metro may make
its own estimate of the number of Residential Customers and
Residential Customer equivalents of the City and such
estimate shall constitute the reported number for the
purpose of determining sewage disposal charges.
3. The monthly sewage disposal charge payable to
•
Metro shall be determined as follows:.
(a) Prior to July 1st of each year Metro shall
determine its total monetary requirements for the disposal
of sewage during the next succeeding calendar year. Such
requirements shall include the cost of administration,
operation, maintenance, repair and replacement of the
Metropolitan Sewerage System, establishment and maintenance
of necessary working capital and reserves, the requirements
of any resolution providing for the issuance of revenue
bonds of Metro to finance the acquisition, construction or
use of sewerage facilities, plus not to exceed 1% of the
foregoing requirements for general administrative overhead
costs.
(b) To determine the monthly rate per Residential
Customer or Residential Customer equivalent to be used
4
•
•
•
•
• •
during said next succeeding calendar year, the total
monetary requirements for disposal of sewage as determined
in subparagraph 3(a) of this section shall be divided by .
twelve and the resulting quotient shall be divided by the
total number of Residential Customers and Residential
Customer. equivalents of all Participants for the October -
December quarter preceding said July 1st; provided, however,
that the monthly rate shall . not be less than Two Dollars
($2.00) per month per Residential Customer or Residential
Customer equivalent at any time during the period ending
July -31, 1972.
(c) The monthly-sewage disposal charge paid by
each Participant to Metro shall be obtained by multiplying
the monthly rate by the number of. Residential Customers and
Residential Customer equivalents of the Participant. An
additional charge may be made for sewage or wastes of
unusual quality or composition requiring special treatment,
or Metro may require pretreatment of such sewage or wastes.
4. The parties acknowledge that, by resolution of
the Metropolitan Council, Metro may impose a charge or
charges directly on the future customers of a Participant
for purposes of paying for capacity in Metropolitan Sewage
Facilities and that such charges shall not constitute a
breach of this agreement or any part thereof. The proceeds
of said charge or charges, if imposed, shall be used only
for capital expenditures or defeasance'of outstanding
revenue bonds prior to maturity.
In the event such a charge or charges are imposed,
the City shall, at Metro's request, provide such information
regarding new residential customers and residential customer
equivalents"as may be reasonable and appropriate for
purposes of implementing such a charge or charges.
5. A statement of the amount of the nonthly
sewage disposal charge shall be submitted by Metro to each
5
•
Participant on or before the first day of each month and
payment of such charge shall be due on the last day of such
month. If any charge or portion thereof due to Metro shall
remain'unpaid for fifteen days following its due date, the
Participant shall be charged with and pay to Metro interest
on the amount unpaid from its due date until paid at the
rate of 6% per annum, and Metro may, upon failure to pay
such amount, enforce payment by any remedy available at law
or equity.
6. The City irrevocably obligates and binds
itself to pay its sewage disposal charge out of the gross
revenues of the sewer system of the City. The City further
binds itself to establish, maintain and collect charges for
sewer service which will at all times be sufficient to pay
all costs of maintenance and operation of the sewer system
of the City, including the sewage disposal charge payable to
Metro hereunder and sufficient to pay the principal of and
interest on any revenue bonds of the City which shall
constitute a charge upon such gross revenues. It is
recognized by Metro and the City that the sewage disposal
charge paid by the City to Metro shall constitute an expense
of the maintenance and operation of the sewer system of the
City. The City shall provide in the issuance of future
sewer revenue bonds of the City that expenses of maintenance
and operations of the sewer system of the City shall be paid
before payment of principal and interest of such bonds. The
City shall have the right to fix its own schedule of rates
and charges for sewer service provided that same shall
produce revenue sufficient to meet the covenants contained
in this.Agreement.
Section 2. Amendment of Section 6 of the Basic
Agreement. Section 6 of the Basic Agreement is hereby
amended to read as follows:

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.

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 City supervisor with express
approval of the City Council is authorized to reduce the
special connection charge to the amount charged to
properties similarly situated.

Chapter Seven
The Growth Management Act requires coordinated planning so that the services' required bynew
residents and their homes and businesses are available as growth occurs. Needed services include
many that are not provided byKing County, such'as'water supply,' local sanitary" "sewers, fire protection,
schools,' energy facilities, and telecommunications. ' King County does provide services such as regional
wastewater treatment, regional solid waste management, and local 'stormwater' management.; :This'
chapter contains policies that guide service provision.
9 -27-04
King County government is a regional and local service provider. Types of regional services provided
include transit, wastewater,treatment, and solid waste management. Local services provided:to citizens •
of unincorporated urban King County and the rural areasyinclude police, building permits, and health and
human services. As annexations and incorporations of unincorporated urban areas. continue, King
County government will focus more on its role as the provider of regional services and protector of the
County's rural and resource areas. The. following policies direct King County's evolving role as regional •
service provider: "
F -101 King County, the cities, special purpose districts and/or local service providers shall
plan as partners. King County's planning will focus on unclaimed urban
unincorporated areas and cities' Potential Annexation Areas.
F -102 King County shall work with cities, special purpose districts, other local service
providers and citizens to identify and distinguish local and countywide services.
Over time, cities will assume primary responsibility for coordinating the provision of
local services delivery. The county will assume primary responsibility for
coordinating the provision of countywide services, including countywide services
that must be delivered within city boundaries. The county will also work with cities,
special purpose districts, and other counties to identify regional service and facility
needs and develop strategies to provide them.
F -103 King County will provide or manage countywide services which include but are not
limited to:
a. Transit;
b. Economic development;
c. Harborview Hospital;
d. Public health;
e. Regional park, trails and open space systems;
f. Waste water collection and treatment;
g. Solid waste management and recycling;
h. Hazardous waste management;
i. Water resource management;
J. Surface water management;
k. Flood warning and floodplain management;
I. Protection and preservation of natural resource lands;
m. Regional Arterial Network (RAN) and freight mobility; and
n. Affordable housing..
F -104 King County will, in cooperation with special purpose districts and /or local service
providers, continue to plan for and provide public services to the Rural Area,
consistent with rural standards and needs.
F -105 To support the intent of the Growth Management Act, King County should work with
cities and other service providers to establish priority areas for public funding of
capital facilities, services and Infrastructure.
7 -2
•'
9 -27 -04
A. Providing a Spectrum of Services
King County and numerous service providers need to, coordinate. planning and.funding activities to ensure
that needed facilities and services are provided in. the.region.
F -201 All facilities and services should be provided In compliance with provisions and
requirements . of the Endangered Species Act...
F -202 King. County should seek to create quality communities by defining the needs and
proposing strategies for full ran9e of public facilities and services, including
physical infrastructure, and health, human and public safety services. King County
should ensure,that there is an adequate supply of pub licfacilities necessary to
support communities..: :. .
F -203 King County should work with the cities, special purpose districts: and other service
providers to define regional and local services and to determine the appropriate
providers,of those services.,
F -204 King County shall work with its neighboring counties, the state, Puget Sound
Regional Council, special, purpose, districts, ports and the cities to identify areas of
shared need and adequate land supply for public facilities. The county's capital
acquisition budget shall reflect the jointly agreed -upon. priorities and time schedule.
F -205 Public and private community service providers should be encouraged to share or
reuse facilities when appropriate, to reduce costs, conserve land and provide
convenience and amenity for the public. Joint siting and shared use of facilities
should be encouraged for schools, community centers, health facilities, cultural
facilities, libraries, swimming pools and other social and recreational facilities.
B. Urban and Rural Services
Although growth will be directed to Urban Areas, it is recognized that Rural Areas have facility and service
needs also.
F -206 Public spending to support growth should be directed to the Urban Growth Area and
prioritized, and coordinated through Capital Facility Plans to comply with the
concurrency requirements of the Growth Management Act.
F -207 In the Rural Area, services provided by agencies should support a rural level of
development and not facilitate urbanization..
C. Identifying Needs for Facilities and Services
Public facilities and services are vital to protect public health, safety and welfare and to protect and
enhance community and environmental quality. Inadequate sewage disposal, for example, could directly
threaten public health. Inadequate groundwater protection could result in unsafe drinking water and
threaten stream flow. Deficiencies in other services, such as police protection or parks, might not raise
7 -3
9 -27-04
severe obstacles to any single new development, but over time could cause general threats to public
health, safety and welfare and deterioration of community quality.,
King County govemment is responsible for assuring that adequate facilities and services are available or
can be made available to support planned growth. This responsibility is carried out by identifying needs for,
facilitiesand services based on the planned amount and location of growth. The mechanism for identifying
needs is capital improvement programming.
The Growth Management Act requires the county to prepare a capital facility plan which includes an
inventory of existing capital facilities owned by public entities, a forecast of the future needs for capital
facilities, including the proposed locations and capacities of expanded or new facilities, and a six -year
plan that will finance the expanded or new facilities.
The Capital Facility Plan Element for King County is comprised of the following four components:
1. Technical Appendix A is an executive summary of documents containing inventories of facilities and
services provided by King County (health and human services and law, safety and justice,
transportation) andthose provided .by other entities (drinking water supply, sanitary sewer collection
and'treatment; schools, fire protection, libraries; natural gas, telecommunications; and electricity).
2. Technical'Appendix A is an executive summary of documents containing the forecast of future needs
for capital facilities, including the proposed locations and capacities of expanded or new facilities:
3. Six -year plan that will finance the expanded or new facilities:
a. Technical Appendix A is an executive summary of the"finance plans for facilities and services
provided by the'county and other entities.
b. Technical Appendix A references the Transportation Needs Report which includes an analysis of
funding capability to judge needs against probable funding resources, and a 20-year financial
forecast'report based on identified needs.
c. Current adopted King County Capital Improvement Program for facilities other than
transportation.
4. Requirement to reassess land use if funding is unavailable to meet existing and future needs:
a. Policies of Chapter Seven, Part I Facilities & Services, Sections B — F.
b. " Chapter Nine, Transportation, Section IV.
D.
Capital Facility Planning
King County and other service providers are required to prepare six -year capital facility plans that
describe needs for the six -year facility and propose funding to meet those needs.
F -208 The capital facility plans and capital improvement programs prepared by all other
agencies which provide services to unincorporated areas of the county should be
consistent with the King County Comprehensive Plan.
F -209 To reduce overall public costs, noise and disruption to the local area during
construction, installation of new or maintenance of existing utility facilities should
be timed and coordinated with other projects that utilize public right-of-ways and
easements, where possible.
F -210 King County's capital facility plans should identify financing strategies to support its
adopted 20 -year growth target and land use plan.
F -211 King County's capital improvement program shall demonstrate that projected needs
for facilities and services can be met within the Urban Growth Area and can be
served in compliance with the concurrency requirements of the Growth Management
Act or, if that is not possible, King County shall determine where and when deficits
may occur and how needed facilities and services might be phased in and or
financed to serve such deficit areas. Alternative phasing and financing strategies
7-4
•

must be identified and determined to be infeasible prior to triggering a land use and
zoning reassessment under Policy F -216.
F -212 School districts which choose to have the county collect impact fees for them, and
water and sewer utilities that provide their services to unincorporated King County
shall prepare capital facility plans consistent with requirements of the Growth
Management Act and King County Code.
F -213 Provision aof.an adequate supply of kindergarten through twelfth grade (K -12) public
schools and K -12 public school facilities is essential to avoid overcrowding and to
enhance the educational opportunities for our, children. King County shall adopt
regulations which are supportive of the permitting of K -12 public schools and K -12
facilities.
E. Addressing:Setvice Deficiencies:..
In the event that needed facilities and services are not available to support either existing: development or
growth, King County will work with other service providers to address the service deficiency:
F -214 King County shall initiate a subarea planning process with any service provider that
declares, through their capital facilities plan, an inability to accommodate projected
service needs; inside their service area.
F -215 King County and its cities should coordinate planning for health and human service
facilities and services. County investments in health and human service facilities
should be targeted primarily to the designated Urban Centers and secondarily to
other locations in the Urban Growth Area and Rural Towns.
F -216 If an area wide sewer, water, or transportation service deficiency is identified, King
County and the applicable service providers shall remedy the deficiency through a
joint planning process addressing capital.improvement programs and long -term
funding 'strategies: If financing and level of service remedies cannot solve the
deficiency, King County shall change zoning to address the problem.,
F. Financing Strategies
King County, cities, and other service providers will work together to address the financing needs of
facilities and services.
F -217 King County shall work with the cities to create a financing partnership for areas of
the Urban Growth Area that the cities will annex. This includes determining
county /regional and city /municipal facilities and services and then committing to a
shared financing strategy to build or provide these infrastructure improvements or
services.
F -218 King County should, in cooperation with other jurisdictions, develop funding
strategiesfor governmental infrastructure that take into account economic
development goals and consider. the costs to, and benefits for, the jurisdictions and
the region.
G. Essential Public Facilities
The region will work cooperatively to site essential public facilities in an equitable manner. Essential
public facilities are defined in the Growth Management Act and include large, usually difficult to site
facilities such as prisons, solid waste facilities, and airports.
.7-5
9 -27-04
F -219 Proposed new or expansions to existing essential public facilities should be sited
consistent with the King County Comprehensive Plan. Listed existing essential
public facilities should be preserved and maintained until alternatives or
replacements for such facilities can be-provided. ':
F -220 King County and neighboring counties, if advantageous to both, should Share
essential public facilities to in crease efficiency of operation. Efficiency, of, operation
should take into account the overall value of the essential public facility JO the region
and the county and the extent to which, if properly mitigated,'expansion'of an
existing essential' public facility located in the county might be more economical and
environmentally sound. •
F -221 King County should strive to site essential public facilities equitably so that no
racial, cultural, or socio - economic group is unduly impacted by essential public
facility siting or expansion decisions. No single community should absorb an
inequitable share of these facilities and their impacts. Siting should consider
environmental "equity and environmental, economic, technical and service area
factors. The net impact of siting new essential public facilities should be weighted
against the net impact of expansion of existing essential public facilities;' with
appropriate'buffering and mitigation.- Essential public facilities that directly serve
the public beyond their general vicinity shall be discouraged from locating in the
Rural Area.
F -222. A facility shall be determined to be an essential public "facility if"it has-one or more of
the following characteristics:
a. The facility meets the Growth Management Act definition of an essential public
facility;
El. The facility is on a state, county or local community list of essential public
facilities
c. The facility serves a significant portion of the county or metropolitan region or is
part "of,a countywide service system; or - -
d. • The facility is the sole existing facility in the county for providing that essential
public service.
F -223 Siting analysis for proposed new or expansions to existing essential public facilities
shall consist of the following:
a. An inventory of similar existing essential public facilities in King County and
neighboring counties, including their locations and capacities;
b. A forecast of the future needs for the essential public facility;
c. An analysis of the potential social and economic impacts and benefits to
jurisdictions receiving or surrounding the facilities;
d. An analysis of the proposal's consistency with policies F -219 through F -222;
e. An analysis of alternatives to the facility, including decentralization,
conservation, demand management and other strategies;
f. An analysis of economic and environmental impacts, including mitigation, of any
existing essential public facility, as well as of any new site(s) under
consideration as an alternative to expansion of an existing facility;
g. Extensive public involvement; and
h. Consideration of any applicable prior review conducted by a public agency, local
government, or citizen's group.
F -224 King County supports coordination of regional water supply planning, sales of
excess water supplies among municipalities in the region, water quality programs
and water conservation and reuse programs.
• •
• H. Water Supply
9-27-04
King County is not a water utility and does not provide potable water to citizens in the region.. it
plays an important role In the coordination or linking.of water supply and growth. Moreover, the county
reclaims water from its wastewater treatment plants.. Reclaimed water can be used for many purposes,
such as irrigation and industrial use which currently utilize potable water sources
Reclaimed water produced by King County must be consistent with the standards contained in the
Washington Department of Ecology's "Orange Book," as promulgated under chapter 90.46 RCW. The
"Orange Book" describes differing levels of treatment that are required to produce different classes of
reclaimed water. King County currently produces only Class A reclaimed water, which is produced using
the highest levels dtreatment.
.
1 Potable Water Systems
Potable water is provided by Group A public water systems having 15 or more connections, Group B
public water systems having 2 to 14 connections, and individual private wells serving one ponnection.
Exempt wells refer to wells that do not require obtaining a water right from the state for withdrawal of
water. These exempt wells are subject to all other rules and regulations other than the requirement to get
a permit from the state to withdraw water: Mater withdrawn from an exempt well for individual or group
• A
domestic water supply cannot exceed 5,000 gallons per day, nor may the water be used to irrigate more
than a half acre of lawn or noncommercial garden: The type of water system required for new
development will depend upon whether a proposed development is or is not located within the Urban
Growth Area is or is not within an approved service area of an existing public water system, and is or is
not able to provide an adequate water supply as required under RCW 19.27.097 and/or RCW 58.17.110.
F-225 Group A water systems shall be responsible for fulfilling their duty to provide
service within their service areas approved under state la*. The service areas for
Group A public'watersystems are defined by Coordinated Water System Plans
approved under chapter 70.116 RCW or by individual water system plans reviewed
by the county and approved by the state. .
F-226 In the Urban Growth Area all new construction and all new subdivisions shall be
served by Group A public water systems except in the circumstance when no Group
A public water system can provide service in a timely and reasonable manner per
RCW 70.116.060 or when no existing system is willing and able to provide safe and
reliable potable water with reasonable economy and efficiency per RCVV19.27.097.
F-227 In the Urban Growth Area, individual private wells are not permitted unless
application of Policy F-226 to a proposal for a single-family residence on an
individual lot would deny all reasonable use of the property. In that case, the well
would be allowed only as an interim facility until service by a public water system
can be provided. The individual well must meet the criteria of the King County Board
of Health Title 13.
F-228 In the Urban Growth Area, if a Group A water provider cannot provide direct service
to new development in a timely and reasonable manner as required under RCW
70.116.060 or chapter 43.20 RCW, a new public water system may be established if it
is owned and operated by the following, in 'Order of preference: ,
a. By the Group A system, in whose service area the system is located, via
satellite management, or
b. By a satellite management agency approved by the State Department of Health
under contract with the Group A system in whose service area the system is
7-7
9 -27-04
located, provided that the existing Group A water system remains responsible
for meeting the duty to serve the new system under RCW 43.20.260.
All new public water systems formed in the UGA shall connect to the Group A water
system in whose service area the new system is located when direct service
becomes available. All known and projected costs for anticipated: connection shall''
be funded at permitting stage of any proposed new construction or new; '
subdivisions.
F -229 In the Rural Area, individual private wells, Group B water systems, and Group A
water systems are all allowed. Creation of a new public water system or the '
expansion of an existing Group B system may be 'allowed to serve new construction
or new subdivisions when no Group A public water system can provide service in a
timely and reasonable manner. per RCW 70.116.060, or when an existing system is
not willing and able to provide safe and reliable potable water with reasonable
economy and efficiency per RCW 19.27.097.
F -230 New public water systems estabflshed in the Rural Area shall be owned and
operated by the following, in order of preference:
a By the Group A public water system in whose service area the system Is located,
by direct service or satellite management by the Group A system,
ti. By a satellite management agency; approved by the State Department of Health
and providing service within the county and under contract with the'Group A
system if it Is located In a Group A system service area; or
c. By the owners of the lots that are provided water by the new system if the new
system is not within the service area of an existing Group A system or not within
the area covered by a satellite management agency. Approval for any such
system shall be conditioned for future ownership or management by a satellite
management agency, when such service becomes available; and for periodic
' review of system operations, as required, by RCW 70.119A.060(2)._ •
•
Ecology has determined that the rivers and streams in the major river basins in King County have no
water available for further consumptive appropriation without harmfully, impacting instream. values. For
that reason; it has by regulation closed those basins to issuance of new water'rights, and has directed
that the natural interrelationships between surface and ground'waters should be considered in future
water allocation decisions in order to avoid adverse impacts to instream flows. The installation and use of
wells that are exempt from ecology's water rights permitting process may further harm those rivers and
streams when the wells are withdrawing ground water that is directly connected to the water in the
stream. The installation of new exempt wells may also create health and safety problems by interfering
with the water supplied by existing wells, and by creating more holes in the ground that can lead to
contamination of entire aquifers. Under K.C.C. chapter 9.14, the Department of Natural Resources and
Parks is to act as lead agency in coordinating the activities of DDES and Public Health in order to ensure
that groundwater quality and quantity are protected, and facilitate implementation of the plans that have
been developed to protect ground water in five groundwater management areas within King County.
F -231 New subdivisions with more than six single - family lots on Vashon -Maury Island and
in closed basins in the Rural Area (as defined in WAC 173 -507, 508, 509, 510, and
515) may not be served by a potable'water system using an exempt well, or a
Combination of multiple exempt wells. One exempt well per subdivision will be
permitted unless more than one exempt well is needed to meet the water flow
requirements for the six residences. New developments in the Rural Area served by
an exempt well, or wells shall not exceed one -half acre of irrigation.
F -232 King County shall work with the State Department of Ecology and the State
Department of Health to ensure that existing provisions of state law that provide for
•}
J
9 -27 -04
measuring water withdrawals or diversions for sources of supply are fully utilized to
meet public health, resource protection, land use, planning and fish recovery
objectives and obligations. Any new or expanding, Group B water system shall have
a totalizing source meter and shall make information from the meter available upon
request of King County.
2. Regional Water Supply Planning
Over the past several years King County has been working cooperatively with many of the larger water
utilities in the region to gather information about regional water demand and supply. King County would
like to use this information to help develop a regional water supply plan.
F -233 King County supports development of a regional water supply plan for the entire
region. Key components of this planning process should include:
a. ^Involvement, oversight and support of elected officials in the region
b. Meaningful public participation including the involy ement of the state and
federally recognized tribes;
Prioritization of future supplies; including airole for conservation "and reclaimed
water;
d. Assigned accountability for implementing conservation and developing new
'supplies and infrastructure such as transmission pipelines; and
e. Legislative changes, if necessary, to implement the plan.
c.
F -234 King County should assure that a regional water supply plan for;all of King County is
prepared in cooperation with water utilities and in coordination with affected
federally recognized tribal, local and state governments. A continuous and
meaningful,public process should be used to develop the regional water supply
plan, resulting in a plan that is adopted by elected public officials in the region and
used by the state in making water resource decisions.', The regional water s' upply
plan should implement and be consistent with growth management decisions made
by local and regional jurisdictions under the Growth Management Act and the
approved water quality and quantity strategies adopted. by the region in compliance
with federal requirements under the Endangered Species Act, Clean Water Act, and
other authorities relevant to water quantity and quality:
F -235 The county will work with water utilities to develop' a water supply plan that
prioritizes an array of potential sources, including conservation and reclaimed water,
and defines a publicly - and state - accepted strategy for how the region could best
meet future demands for water:'' During development of the regional water supply
plan, the county will work In concert with water utilities to evaluate the projected
water demands for population growth and other out of stream needs identified under
the Growth Management Act, Endangered Species Act`response provisions in plans
developed under the state's Salmon Recovery Act, and Clean Water Act
requirements for water quality.

3. Utility System Interties
Water utilities obtain water supplies from many varying sources. Some water utilities receive the vast
majority of their water supply from wells. Yet others receive substantial portions from municipal
watersheds and reservoirs. The varying water supply sources can differ substantially in terms of
dependability of output, so`that while one water utility may have excess capacity, a neighboring water
utility could be experiencing severe shortages and be unable to adequately serve their customers.
F -236 King County supports interties that allow the transfer of water resources among
water utilities in urban areas to meet the projected demands for growth. The transfer
7 -9
9 -27 -04
of water must be consistent with locally adopted growth management plans, regional
water supply plans, groundwater plans, watershed plans, and approved Coordinated
Water System Plans; and implement approved Endangered Species Act response
requirements and Clean Water Act requirements.
F -237 King County supports the development of appropriate regional water intertie capital
projects, subject to approval from appropriate local, state, and federal agencies and
consistent with Policy F -236.
4. Water Reuse, Conservation and Accounting
King County residents depend on proper management of water resources to ensure adequate and
reliable water supplies, and protection and preservation of natural resources: As a regional service
provider, King County plays a role, along with others, in managing these water resources for long -term
sustainable supply and protecting the Tong -term functions and values of natural water systems. As part of
its responsibilities, King County reviews water utility plans for those utilities serving unincorporated King
County and encourages the inclusion of elements related to water reuse and conservation in the plans.
The King County Code directs county programs to specifically act as a clearinghouse for data related to
groundwater quality and quantity in order to facilitate, implementationby King County and others of the
groundwater management plans that have been developed for major portions of King County:
F -238 King County's water reuse Programand projects, as well as water reuse and water
supply /resources, should be coordinated with a regional water supply plan in
accordance with state and federal standards and coordinated with comprehensive
land use plans
F -239 King County shall partner with utilities to publicize water conservation and encourage
best management practices that conserve potable water supply through measures
that include use of alternative supplies such as reclaimed water.. In exercising its role
in reviewing utility water system plans, King County Utilities Technical Review
Committee (UTRC) shall encourage water purveyors to include aggressive
conservation and reuse'measures where applicable, as well as development of new
sources to support planned land uses with reliable service at minimum cost. Efforts
to encourage the use of reclaimed water shall focus on existing and proposed source
suppliesfor barge water users, such as golf courses and cemeteries.
F -240 In its review of water comprehensive plans, the King County Utilities Technical
Review Committee shall consider the following::
a Consistency with land use plans and development regulations adopted under the
Growth Management Act;
b. Approved or adopted regional water resource plans, including basin plans,
groundwater plans, watershed -based conservation and recovery plans
developed under ESA, salmon recovery plans developed under chapter 77.85
RCW, water resource plans developed under chapter 90.54 RCW, watershed
plans developed under chapter 90.82 RCW, and a regional water supply plan or
water resource management plan; and
c. The county's Regional Wastewater Services Plan.
F -241 In reviewing proposals for modified and expanded service area boundaries for
municipal water suppliers, the Utilities Technical Review Committee shall consider,
in addition to Policy F -240:
a. Compliance by the water system with its comprehensive plan, including water
conservation elements; and
b. Whether it can meet its duty to provide service within its service area, as
required under chapter 43.20 RCW.
7 -10
•
9 -27 -04
The county shall not approve a water system plan with a proposed service area
where the water system is unable to provide service for one or more of the reasons
identified in RCW 43.20.260. This does not preclude a modified Or expanded service
area boundary,for the water system in order to correct problems and provide reliable
potable water service within the proposed modified service 'area.
F -242 The Utilities Technical Review Committee should develop a water accounting
program in conjunction with affected water utilities. The water accounting program
should coordinate information on the rate, timing, and location of new development
with theprojected ability of water utilities to issue certificates of water availability.
5. Resource Management and Protection.
Water system reservoirs and watersheds often serve a number of functions. These functions can include
open space, recreation,.forestry, and resource management. However, each function must be weighed
against the primary purpose of such reservoirs and watershed, which: is to provide and"protect supplies of
potable drinking water...
•
F -243 Public drinking water system reservoirs and their watersheds should be managed
primarily for the protection of drinking water, but should allow for multiple uses,
including recreation, when such uses .do: not jeopardize drinking:waterquality
standards. Public.watershedsmust also be managed to protect downstream fish
and agriculture resources.,
F -244 Groundwater -based public water supplies should be protected by preventing land
uses that may adversely affect; groundwater quality or quantity to the extent that the
supply might be jeopardized.
I. Public Sewers and On -Site Wastewater -Treatment and Disposal. Systems
King County adopted the Regional Wastewater: Services Plan in 1999.. It called for a new.north treatment
plant to be in operation by 2010 with a capacity of 36 million gallons per day (mgd). King. County is
proposing to build the new wastewater system. The Brightwater System will include a treatment plant to
provide secondary treatment of wastewater, pipelines and pump stations to carry wastewater to and from
the plant, and an outfall to discharge the treated wastewater to Puget Sound.
King County has selected the location of the Brightwater facilities at what is referred to as the. Route 9-
195th Street System with an effluent corridor along NE 195th Street and a marine outfall in Zone 7S.
The siting process has taken many years and is the focal point of a comprehensive Environmental Impact
Statement, which is likely to be issued in November of 2003. Snohomish County and cities in the
Brightwater service area have participated actively in the siting and environmental review process.
In addition to King County's role as the regional wastewater treatment provider, the Seattle -King County
Department of Public Health is the agency responsible for permitting on -site wastewater treatment and
disposal systems (septic systems). In addition, King County reviews sewer utility comprehensive plans.
F -245 In the Urban Growth Area, all new development shall be served by public sewers
unless:
a. Application of this policy to a proposal for a single - family residence on an
individual lot would deny all reasonable use of the property; or
b. Application of this policy to a proposal that has a vested land use application for
the redevelopment or expansion of an existing use as well as an approved

septic design from Public Health — Seattle and King County, would render
approval of the land use permit void; or
c.. As permitted by policy CP -933.
F -246 In the Urban Growth Area,,King County and sewer utilities' should jointly prioritize •
the replacement of on- site°systeins that serve existing development with public
sewers, based on the risk of potential failure. County and sewer utilities should
analyze public funding options for such conversion and should *prepare'conversion
plans that will•enable quick and cost - effective local response to health and pollution
problems that may occur when many on -site systems fail in an area.'.
F -247 City -owned parks that are redesignated from rural to urban to allow future annexation by a
city and that are subsequently served by public sewers shall be tightlined. This policy
applies to parks that were redesignated from rural to urban on or after September 20, 2004.
F -248 The existing public sewer system in the Town of Vashon cannot be expanded to
serve land beyond the boundaries of the town, except as provided in Policy F -249
and as consistent with Title 57 RCW. On -site systems, community .on- site systems
or decentralized treatment systems may be used as appropriate for planned growth
in other Rural Towns.
F -249 '`Public sewer expansions shall not occur in the Rural Area and on Natural Resource
'Lands except where needed to address specific health and safety problems
threatening the existing uses of structures or the needs 'cif public schools or public
school facilities. Public sewers may be extended, pursuant to this policy, only if
they are tightlined and only after a finding is made by. King County that no
reasonable alternative technologies are technologically or economically feasible.
Utility providers shall ensure, through a signed agreement between the school
district and the utility provider, that any sewer service permitted for the school
.district is designed only to`serve public schools or-Public school facilities.Public
sewers which are allowed In the Rural Area or on Natural Resource Lands pursuant
to this policy shall not be used to convert Rural Area land or Natural Resource Lands
to urban uses and densities or to expand permitted nonresidential uses;
F -250 Sewer facilities such as pump stations, force mains and trunk lines that do not •:
provide connections to the Rural Area may be located in the Rural Area only when
they are identified in a King County - approved comprehensive sewage system plan
and upon a finding by King County that it Is technically necessary in providing
service to the Urban Growth Area. •
F -251 On -site wastewater treatment systems in the Rural Area and Natural Resource Lands
should be designed, built and operated as permanent methods of sewage disposal.
F -252 King County should monitor on -site systems that have shown evidence of failure or
potential for failure. The data should be used to correct existing problems and
prevent future problems. King County should analyze public funding options for
correcting on -site wastewater system failures which may include, where feasible and
otherwise consistent with this plan, conversion to community sewage systems or
installation of public sewers.
F -253 Collective on -site systems may be used only in the following circumstances in the
Rural Area and Natural Resource Lands:
a. Existing on -site systems are failing within an area and the Seattle /King County
Department of Public Health concurs that long -term individual on -site system
repairs are not feasible and /or water quality is threatened by the presence of or
7 -12
9 -27 -04
potential for health hazards resulting from inadequate on -site wastewater
disposal methods;
b. An authorized public agency will manage,the community system; and
c. The community system is designed only to serve existing structures'and Tots
and cannot be used as a basis to increase density onto expand permitted .
nonresidential uses. Substandard vacant lots must be combined to the extent
feasible to 'meet rural density policies: Management of the community system
must be by an authorized public agency.
J. Solid Waste
Appropriate management Of solid waste to protect the environment of King County,is essential to public
health. Responsibility, for management of solid wastes generated by unincorporated area residents and
businesses is shared by waste haulers certified by;the Washington Utilities and Transportation
Commission and the King County Solid Waste Division.
F -254 Solid waste should be handled and disposed of in environmentally sound ways that
protect the quality of air, water and public health..
F -255 King County shall divert as much material as possible from disposal to reduce the
overall costs of solid waste management to county residents and businesses,
conserve resources, protect the environment, and strengthen the county's economy.
F -256 Solid waste management should be planned. and disposal capacity provided on a
regional basis. : ^
F -257 Solid waste handling facilities should be dispersed throughout the county In an
equitable manner.
K. Surface Water Management
Surface water management activities address both the quantity and quality of water entering the natural
environment. .Urban areas are largely covered with impervious surfaces (e.g., buildings, streets,. parking.
lots) that cause increased runoff and are a source of pollutants. Management in the Rural Area is
important, too, because of the potential adverse impacts of forestry, agricultural, and livestock practices.
Prevention or mitigation of flooding, erosion, sedimentation, and water quality and habitat degradation is
important for both the built and natural environments.
F -258 To reduce flooding, erosion and sedimentation, prevent and mitigate habitat loss,
enhance groundwater recharge and prevent water quality degradation, the surface
waters of King County shall be managed through plans, programs and regulations
developed by. King County in cooperation with affected jurisdictions whenever
possible.
F -259 A watershed approach shall be taken to surface water management, with
responsibility shared among King County and affected jurisdictions. This approach
should emphasize prevention of water quality degradation through education
programs and implementation of best management practices to reduce pollution
entering surface waters, including Puget Sound.
F -260 In the Rural Area, King County shall minimize the use of constructed facilities for
surface water management and maximize the use of natural systems, provided that
the ecological functions of the natural systems are not harmed. The county should
provide incentives to keep these natural systems intact. Natural systems are also
preferred in the Urban Growth Area, but it is recognized that structural systems will
7 -13
9 -27 -04
be needed to realize urban growth and density goals. ,King County will plan and
manage surface waters on a watershed basis pursuant to Policies E -123 through E-
129. To accomplish this goal, water should not be diverted from one watershed into
another, nor from one drainage basin into another, unless no other-reasonable
alternative is available for managing surface water run -off within the same watershed
and drainage basin. Where such diversions are permitted, King County will require
such environmental analysis and mitigation as is needed to protect surface water
resources from significant adverse impacts.
F -261 In the Urban Growth Area, regional and shared surface water managements facilities
should be encouraged to support infill development to preclude the need for ,
individual on -site facilities, provide development Incentives; encourage efficient use
of land, and reduce overall facility" maintenance -costs: These facilities should be
planned and financed through public and private partnerships.
F -262 Regional and shared stormwater facilities should be funded through an adequate
and equitable funding'mechanism.'Stormwater facilities required of new
development should be designed and built for low -cost, long -term maintenance.
F -263 King County should work cooperatively with 'other Jurisdictions to develop and
implement plans and programs that aaddress the proper treatment and/or disposal of
the wastes generated from maintenance ofstonnwater facilities.
F -264 King County should work with jurisdictions to identify and agree upon regional and
local storm and surface water management responsibilities and agree on the
division of storm and surface water management service provision.
L. Floodplain Management
Both the Washington State Growth Management Act (chapter 36.70A RCW) and Title 86 RCW,' Flood
Control require interlocal consistency and coordination for effective floodplain management. Counties
have been directed to prepare comprehensive floodplain management plans with participation Of the
cities. Under the King County Countywide Planning Policies (CPPs), comprehensive floodplain
management plans, regulations, and programs within-all jurisdictions in any of the major river basins in
King County must be consistent with the King County Flood Hazard Reduction Plan. As such, King
County is a regional service provider for floodplain management.
F -265 King County should participate with cities to prepare, update and implement
comprehensive flood hazard reduction plans that meet or exceed standards
established by the National Flood Insurance Program.
F -266 King County shall maintain a regional flood warning program for the major river
basins in King County.
F -267 Maintenance of flood protection facilities on the mainstem rivers in King County
should reflect a prioritized approach; based.upon the Flood Hazard Reduction Plan
policies, within available funding levels. Additional funding sources and
partnerships in support of maintaining and improving flood protection facilities
should be sought whenever possible.
7 -14
9 -27 -04
Energy and,electronic communications systems . are important public services that must be coordinated with
land use planning. King County's economy and quality of life depend on readily available energy and ,
telecommunicationsresources. Efficient use of energy resources can minimize long -term costs to the
individual and to society:"
One or more local, state or federal agencies regulate retail energy providers in King County. Gas and
electric utility resource�and conservation plans are approved by other agencies through "a public process.
The Washington Utilities and Transportation Commission (UTC) reviews and accepts plans of private
electric and gas utilities, and the Seattle City Council approves the plans of Seattle City Light.. Electric
and gas utilities operate in King County under franchises with the countj/'for use of the Public right-of-way.
The UTC also defines the costs that private utilities can recover, approves rates, sets service standards
and resolves customer` complaints. However, unregulated firms responding to market conditions may
develop many" new electricity resources.
Telecommunications services are regulated by'several entities, including the-Federal Communications
Commission and the Washington Utilities and Transportation Commission:, King County.has some
. regulatory authority 'Over telecommunications "services through franchises andithe development approval
process.
A. Energy
1. Consistency with Land Use Plans
State law mandates that electric and gas public service companies provide the same level of service on a
uniform basis, regardless of location. (RCW 80.28.110). Policies in this chapter encourage the utilities to
prioritize capital improvements in a manner consistent with land use.
Disruption of traffic due to public and private road projects frequently occurs in King County. Policies in this
chapter support existing programs to notify utilities of upcoming projects to build, expand, or maintain county
roads so utility and road construction can be coordinated.
Distribution systems for gas, electric and telecommunications installation in new construction now have
separate permits. Permit consolidation is desirable as a means to expedite review while protecting the
environment. Countywide Planning Policy ED-23 encourages jurisdictions to establish a master utility
project.
F -301 Energy providers' resource and facility plans should be consistent with the King.
County Comprehensive Plan and should provide for a reliable source of energy in
the event of natural disaster or other potential threats of disruption to service.
F -302 King County should coordinate public road construction and maintenance projects
with utility construction and maintenance.
2. Conservation and Alternative Energy Sources
King County Countywide Planning Policy CO -6 states that "aggressive conservation efforts shall be
implemented to address the need for adequate supply for electrical energy and water resources, protect
9 -27 -04
natural resources, and achieve improved air quality." King County has a continued commitment to energy
conservation, use, of renewable resources and quality enforcement of the energy code.
Solar features in building design can be cost effective in the Pacific Northwest. Solar energy is renewable,
clean and reduces the use of fossil fuels. King County encourages the use of both passive and active solar .
energy use through subdivision and building design.
Gas and electric utilities offer low- income energy assistance programs. All feasible actions to increase the
availability of conservation measures tolow- income residents should be pursued, such as public-private_
cooperation and combining existing rehabilitation efforts with installation of energy efficiency measures.
F -303 Efficient energy consumption, conservation, the use of renewable technologies, and
energy responsible land use decisions should be a priority in King County. King
County promotes the maximum use of energy conservation and renewable energy
resources now, while leaving options for increasing' conservation and renewable
technologies in the future:
F -304 To implement the Countywide Planning Policy of aggressive conservation and
promotion of regional air quality; King County "should:
a. Effectively enforce the energy code as part of the general permit process;
b. Provide density Incentives through the zoning code for energy- efficient
developments; „ .
Continue to improve the fuel efficiency` and emissions of the county -owned fleet
of motor vehicles;
d. Work with utilities to become a model of energy efficiency in facilities owned or
operated by Metropolitan King County; and
c.
e. Seek cost - effective ways to capture energy from county operations which'other-
wise would be lost, such as methane gas from landfills and sewage treatment.
F-305 King County shall continue to explore methods of reusing or marketing methane gas
from its sewage treatment plants; and shall explore the feasibility of expanding these
methods to the methane gas produced at its landfills.
F -306 King County encourages the use of solar energy and should protect solar access.
.=t
F -307 King County should expand the availability of energy efficiency measures to low-
income residents.
3. Electric Utilities
The four -state Northwest Conservation and Electric Power Plan of the Northwest Power Planning Council
provides a blueprint for the development of electricity resources. Bonneville Power Administration and other
federal agencies, the region's utilities, state and local govemment, private businesses and the people of the
Northwest all participate in implementing the Council's goals. Electric utilities serving King County include
Bonneville Power Administration, Seattle City Light, and Tanner Electric Cooperative. Puget Sound
Energy provides both electricity and natural gas service.
Hydropower is the largest single source of our existing electrical power, with the county's major suppliers
located outside King County. These include the Grand Coulee, North Bonneville and Ross Dams. Federal
and state approvals for hydroelectric dams are difficult and time - consuming to acquire, making hydropower
a small part of projected new regional power - generating resources.
Existing hydropower facilities in King County include Snoqualmie Falls, Cedar Falls, Twin Falls, Weeks
Falls;'and Black Creek. Proposed projects include expansion of Snoqualmie Falls and new facilities at
South Fork Tolt River, Hancock Creek and Calligan Creek (both are tributaries of the North Fork
7 -16
•
•
9 -27 -04
Snoqualmie), the Upper South Fork Snoqualmie and Martin Creek near Stevens Pass. Few additional
projects beyond these listed are expected to be built in King County.
The Federal Energy Regulatory Commission licenses such projects, but in doing so must consider existing
plans and policies of public and private jurisdictions. While power generation benefits the public, care must
be taken to ensure that small hydroelectric projects are constructed in an environmentally sound manner,
directing new, small hydropower facilities, for example, to streams that do not have anadromous fish.
Construction and operation must also be consistent with the intended functions and uses of forestlands,
where most small hydroelectric projects are located.
Gas -fired combined cyclencombustionturbines are expected to dominate new resource additions. These
facilities typically fall below`the size threshold for the Energy Facilities Site Evaluation Council's siting
process. While these facilities have a relatively small physical footprint and are relatively clean, they do
pose potential threats to local air and water quality.
F -308 To address the cumulative effects of multiple energy facilities; King County should
continue to participate in the licensing and relicensing processes for all existing and
proposed small hydroelectric projects within King County. Individual project
reviews should address consistency with designated land uses and environmental
protection goals. 'Specifically, hydroelectric projects should: "
a. Not significantly interfere with commercial forestry operations;
b. Be located and operated in a manner ,such that impacts to salmonid fish and
wildlife are minimized;
c. Avoid unstable and erosion- prone areas;
d. Include 'performance bonding to fund erosion control,
e. Provide full mitigation for construction and operation impacts;
f. Avoid, to the extent practicable,' diminishing scenic values; and
Incorporate adequate public safety measures. '
F -309 King County and the utilities should Identify and preserve corridors to accommodate
future electric power transmission and distribution lines. Corridor designation
should include:
a. ' Identification of appropriate shared uses and recognition of the values provided
by,nonutility uses, such'as recreation;
b. Recognition of county roads as utility corridors; and ;
c. Evaluation of proposed facility plans on a system -wide basis, rather than project -_
by- project.
F-310 When new, expanded or upgraded transmission is required, use of existing corridors
that have above- ground utilities should be evaluated first. King County should
facilitate appropriate corridor sharing among different utility types and owners.
F -311 New electrical distribution lines should be installed underground where reasonably
feasible and not ahealth or safety concern. The county should encourage
underground placement of existing distribution lines through such tools as local
improvement districts.
Public concern exists over the potential health effects of electrical power lines. The concern focuses on the
effects of extremely low level electromagnetic fields, called ELF /EMF or simply EMF. Seattle -King County
Department of Public Health currently responds to inquiries from citizens about EMF and keeps abreast of
current research. The following policy recognizes the inconclusive nature of the data conceming EMF and
the need to have an informed citizenry through public disclosure of available research about the potential,
health risks. Scientific evidence to -date does not support firm conclusions about the existence of adverse
health effects related to EMF.
9 -27 -04
F -312 King County will monitor scientific research on potential human health effects of
extremely low frequency electric and magnetic fields (EMF). If federal or state
agencies promulgate rules to reduce exposure to EMF — through changes in the use
of appliances, construction practices, the location of electrical infrastructure or
other activities - the county shall inform its citizens and take appropriate actions.
4. Natural Gas
The most thermally efficient use of natural gas is in "direct applications." For example, to heat homes and
businesses, the use of natural gas can reduce the demand for additional electricity. The choice of fuel shall
be based on market conditions, with the customer comparing various,fuels..Many homes and businesses in
King County do not have, the, choice of natural gas, however, even within the Urban Growth Area::"
Other factors that currently limit natural gas availability include state utility regulations, building and 'plumbing
codes, and rebate programs that favor electric heat. Because of these barriers, most multifamily housing is
built with electric heat, a significant. consideration given that they represent a large share, of projected new
housing units in urban King "County.
F -313 King County ' should: work to'rem.ove barriers to the availability and efficient use of
natural gas. .:
5. Hazardous Liquid and Gas Transmission Pipelines
Hazardous liquid and gas transmission pipelines, as defined by RCW.81.88.040 and WAC 480 -93 -005,
consecutively, provide a vital service of transporting hazardous materials from one.location to another.
Long- distance transmission pipelines move,a variety,of hazardous materials, including crude oil,
petroleum products, natural gas and hazardous liquids, such as anhydrous ammonia. ;Pipeline rupture or
failure can result in release of these materials, which are highly flammable, explosive or toxic. The
policies in this chapter identify public values and goals to assure that the transmission of hazardous
materials by pipeline address public health and safety..
The, Federal Energy Regulatory Commission (FERC) regulates the location, construction and operational
conditions' of interstate' natural gas pipelines through, its' certification process. The state and federal
govemment regulate the location, construction and operational conditions of hazardous liquid and
intrastate gas pipelines through the Energy Facility Site Evaluation Council (EFSEC) , In its review of
pipeline applications, however, EFSEC must determine whether the pipelines -are consistent with county
land use plans and zoning codes. Thus, King County's authority to regulate the location of pipelines is
through the comprehensive plan and development regulations..
F -314 King County recognizes that federal and state regulatory programs govern the
design, construction, and operation of hazardous liquid and gas transmission
pipelines. To preserve the safety and reliability of the hazardous liquid and gas
transmission pipeline system, land use, zoning and regulations shall be consistent
with state and federal requirements.
F -315 Any new hazardous liquid and gas transmission pipelines proposed for construction
in King County shall meet the county's development regulations, including but not
limited to, King County's zoning code, building code, grading code, and shoreline .
management code.
King County anticipates that few new hazardous liquid or gas transmission pipelines will be constructed in
the near future. However, as existing pipelines age and the relationship between resources, refineries
and markets changes overtime, new pipelines will need to be constructed. Hazardous liquid and gas
transmission pipelines are best constructed away from locations where large numbers of people
assemble. King County recognizes however, that under some circumstances, new gas transmission

.Grease:Interceptors,
The City requires grease interceptors on all buildings where food preparation occurs and at
locations determined by the City as necessary for the proper handling of liquid wastes; Grease
interceptors must comply with Appendix H of the Uniform Plumbing Code and the following
criteria::'"
• Provide a double baffle type, interceptor- with 6 inch, lines and details, referenced to _related
plumbing sheets.
• For sizing, consider the meals per hour as equal to a restaurant's ,seating capacity.
• Locate the vault outside the building, between 5 feet and 25 feet from the building
foundation.
■ Install the interceptor, so that, gray water from sinks, floor drains, drains under garbage, .
compactors, is routed through the interceptor. DO NOT route dishwashers through the
grease interceptor. NOTE: Route ONLY gray water through the interceptor'-
• Every three months the owner must completely pump out the ,interceptor..: Businesses that
generate small amounts of grease may, with the City's approval, pump the interceptor on a 6-
month schedule. At any time, the City may inspect the interceptor, and require. more frequent,
service.
5.5 Components of Pumped Facilities
5.5.1 Lift Stations
Lift stations within the City of Tukwila must be designed and constructed to the following
minimum requirements:
• Location and Flood Protection: Wastewater lift stations must be located to provide the
minimum amount of nuisance to local or proposed residential or commercial development.
Lift station design must take into account noise control, odor control and station architectural
design. Space for future expansion should be provided as necessary. If possible, lift stations
must be located at elevations above the 100 -year flood. If it is not feasible to locate above
the 100 -year flood plain, stations must be protected such that a 100 -year flood does not
damage the facility. All lift stations must be designed to operate during the 25 -year flood.
• Pumping Rate and Number of Units: Each lift station must have a minimum of two pumps.
Each pump must have the capability of pumping the design flow. For lift stations with more
than two pumps, each pump must be capable of pumping the design flow with any one of the
pumps out of service.

DRAFT
5.5.2. Pumps
Wastewater pumps must have the capability of passing a 3 -inch diameter sphere. Pump suction
and discharge openings must be a minimum of 4 inches in diameter: All pumps shall operate
under a positive suction head. The pumps must operate with the use of an approved control
system that senses the water level in the wet' well and must automatically alternate the pump in
use., Each lift: station must be equipped with either a standby generator :or must have the required
connections to allow the use of a portable generator. For lifft` stations that utilize portable
generators, an emergency overflow connection must be provided of sufficient capacity as

Section 6
Wastewater Collection System Evaluation
6.1 Introduction
This section presents an analysis of a portion of the City of Tukwila's wastewater collection and
pumping system. City of Tukwila engineering and operations personnel evaluated the current
condition of the sewer system and determined that in most sanitary sewer drainage basins
described in Section 2 capacity and performance is satisfactory for current and future flows. The
Central Business District (CBD) is where the largest flows occur, where most growth is
occurring, and where the City has most concerns regarding the current and future capacity of the
sewer collection system. Hydraulic modeling was performed in this area to evaluate the
adequacy of existing facilities for conveying current and future flows, and to aid in determining
improvements that would ensure future viability of the collection system.
6.2 Hydraulic Modeling Approach
Tukwila's sewer system was analyzed using the stand -alone version of the hydraulic modeling
software program, SewerCAD, version 3.1. The SewerCAD software is a Microsoft Windows -
based program in which an operator can enter all of the system properties and display them on
the monitor in a graphic format. The model was created specifically for this project and does not
include the entire Tukwila collection system. The area included in the model is described more
fully below.
6.2.1 Model Coverage
The SewerCAD model was developed using existing information from the City of Tukwila. The
area covered by the model includes the CBD and a residential area immediately north of
Interstate Highway 405 (I -405). (See Exhibit 6 -1).
The CBD is more fully described as the area bounded by I -5 on the west, 1 -405 on the north, the
Green River on the east, and Segale Park Drive C on the south. A small portion of the CBD is
located east of the Green River, immediately south of Andover Park East. In general then, the
CBD is within Drainage Basins No. 8, 11, 12, and 13 that are described in Section 2 and shown
in blue on Exhibit 6 -1.
The residential area is roughly bounded by I -405 on the south, the Green River on the east, South
147th Street on the north, and 54th Avenue South on the west. This area is included in the
analysis because it drains by gravity to a pump station that receives wastewater within the CBD.
Exhibit 6 -1 shows this portion of the sewer system that was modeled. It is essentially within
Drainage Basin No. 4 that is described in Section 2 and also shown in blue on Exhibit 6 -1.

6.2.2 Data Collection and Model Creation
Information on the Tukwila wastewater collection system was obtained from Record Drawings
stored in the Tukwila Public Works Department files. Drawings showing pipe alignments, size,
length, and connectivity, manhole elevations (rim and invert);: and pump station wet well size
and locations were used to create a base model. A map of the City of Tukwila was inserted into
the background to aid in, the locating' each manhole. A copy of.the graphic version of the
model is included in Appendix G, which also includes tables summarizing"model data. Sanitary
sewer model basins were established based on this information. �Themodel basins are shown in
yellow and designated by letters in Exhibit 6 -1.' --
Information on pumps and wet wells was limited. For the purposes of the model, wet wells were
included as 10 -foot diameter vaults: Single operating points for pumps Were (based on
estimated pump capacity) and the total dynamic head for the given flow rate was adjusted so the
pumping rate would match the estimated pump, capacity. -
Flows entering the - collection system at specific nodes were developed from the flow projections
included in Section .4 of this Plan. Table 6 -1 lists the demands by sanitary sewer model basin.
Businesses that :supply high flows have been singled out and their flows have been input at the
manhole nearest the connection. Average flows as shown in Table 6 -1, were increased by 20
percent to simulate peak-flows. An additional allowance for I/I has been included in the model
that increases flow in the lines by another 30 percent.
Model Basin G in Table 6 -1 and Exhibit 6 -1 does not include the anticipated flows from the
proposed "Tukwila South Development" (see Section 2.3). An EIS has been prepared for the
development, and the EIS flows of approximately 1.42 million gallons per day (mgd). are
projected to enter the Tukwila system. The effect of these additional flows was evaluated as part
Of the SSP.
6.2.3 Calibration
There was no attempt to calibrate model against existing flows. However, modeled pump station
operations were consistent with Tukwila's operational experience at pump stations in the
wastewater conveyance system.

6.2.4 Simulation Procedure
The analysis of the Tukwila CBD sewer system was completed in the following steps:
• Evaluate the existing system to determine if there are any locations where flow in individual
pipeline segments during peak flow periods was greater than 80 percent of the capacity of the -
individual pipe segment.
• If there, are any capacity issues, run simulations to identify the . necessary improvements to
provide adequate capacity in all pipe segments so that the flow was not in excess of 80
percent of the maximum capacity of the pipe segment.
• Run simulations of the 20 -year flow projection (without consideration of the proposed
Tukwila South Development) to determine if the existing system would have capacity issues.
• If there are any capacity issues, run simulations to identify the necessary improvements to
provide adequate capacity in all pipe segments so that the flow was not in excess of 80
percent of the maximum capacity of the pipe segment.
• Run simulations of the 20 -year (2005 -2024) flow projection with the proposed Tukwila
South development to determine if there were any new capacity issues.
• If there are any capacity issues, run simulations to identify the necessary improvements to
provide adequate capacity in all pipe segments so that the flow was not in excess of 80
percent of the maximum capacity of the pipe segment.
• Run simulations of the 6 -year flow projections to determine what improvements identified in
the 20 -year improvements would be necessary in a 6 -year time frame.
6.3 Existing Collection System Evaluation
Steady state simulations were run for the existing system with existing peak flows plus an
allowance for I/I distributed throughout the collection system. The results of the simulations
indicate that there are no pipe segments flowing at more than 60 percent of capacity. These
simulations were run with all the pump stations in operation. Capacity of each of the pump
stations (with a single pump in operation) was in excess of the inflow to the wet well.
6.4 Future Collection System Evaluation
The analysis of the 20 -year projected flows (without the new Tukwila South Development)
yielded results similar to the existing flows. There are no pipe segments that are flowing at more
than 60 percent of design capacity and peak flow to the pump stations is less than the pump's
capacity.
Once the Tukwila South Development flows are added to the system (approximately 1.42 mgd
average daily flow at full buildout) there are needs for additions to the existing collection system
north of 180th Street. A new sewer will be constructed in Southcenter Boulevard from Minkler
to S 180th Street as part of the Tukwila Valley South Project. Flows from the Tukwila South
Area development will enter this pipeline and flow to the pump station at Minkler and Andover
Park West. Capacity in the new 20- to 24 -inch line is projected adequate to meet the full
Tukwila South Development flow rates; however, the pump station at Minider and Andover Park
West appears to be undersized. The existing maximum flow rate for the pump station is

• DRAB •
800 gpm, while the anticipated peak inflow to the pump station in the future is approximately
1,175 gpm. Thus, the pump station should be revised to provide service for the future flows.
In the piping leading up to the pump station there is only one pipe segment that exceeds 60
percent of its design capacity.
6.5 Recommended Improvements
Improvements in the study area to meet the projected demands of the study are presented in

7.3.1 , Grease Accumulations
Over the years the Tukwila sewer system has experienced recurring grease accumulation in side
sewers, collector sewers, trunk sewers, manholes, wet wells, and forcemains. In the past, grease
problems required, a significant . portion of the City's maintenance, ._ budget that could be put to.
:
Excessive grease entering the King County WTD interceptor, flushing and cleaning program.
better use on an ongoing, s stem -wide preventative Maintenance
gr g g y ceptor system is also in violation of the
agreement between the City and King County WTD.
The City is working on a grease interceptor ordinance to alleviate much of the routine "operation
problems.: ° However; budget restraints prevent the City. froth implementing a routine. grease
interceptor inspection program. Thus significant grease accumulation problems do. arise. On
going problems exist in the wet wells of Lift Station No. 2 and at several-other stations.
7.3.2 ...Sewer•Sags
A second operating problem that has led to operating problems in the past is development of sags
in existing sewers. These sags are due to settlement in the sewer lines as a result of poor soil
conditions. The sags allow wastewater to pond and solids t� 'Settle: 'This reduces the capacityof
the sewer; in these] areas. In areas where oil and grease are a problem, a sag. in the sewer line
compounds the problem. =. Odors can also develop. The City has been improving its design and •
construction standards such that this problem is being reduced. However, particularly in' older
sections of the system, a few instances of pipeline sagging problems do occur.
7.4 Maintenance Program
The hub of the City's sewer maintenance operations is at the Maintenance Facility on Minkler
Boulevard. Water, streets and stormwater maintenance operations, as well as those for the
sanitary sewer system, are headquartered at this facility.
7.4.1 Maintenance Management
The Maintenance Operations Manager sets goals, establishes work priorities, and makes plans to
help achieve the organization's goals for the year The Sewer Superintendent has the
responsibility to plan, organize, direct, and control the workforce to achieve the division's goals.
This position is also responsible for developing maintenance work standards, interfacing with the
sewer engineer, setting up repairs, reviewing plans for current and future development, design of
pump stations, and I &I work planning.
7.4.2 Preventive Maintenance
The City of Tukwila has a preventive maintenance program for the sewer system. Due to the
makeup of the system, an exhaustive preventive maintenance . program is not required. The
primary component .that requires regular servicing is the lift stations. Maintenance guidelines
and procedures for preventive maintenance are generally as follows:
• Lift Stations: A regular inspection is made of the lift stations within the system. Running
times are monitored and recorded to determine pump life. The pumps are regularly serviced
and lubricated per the recommendation of the pump manufacturers.
Operations and Maintenance 7.4
FM 1 Ines

DRAFT
• Sewer Mains and Force Mains: Sewer mains are flushed and jet cleaned once per year to
ensure satisfactory service and reduce plugging problems.
7.4.3 TV Inspections
The City. of Tukwila has an ongoing TV inspection program to identify the problem areas in the
system. In past years as much as 20,000 linear feet had been inspected annually. In areas with
significant problems identified, the City has repaired the sewer by removal of the existing sewer
and construction of a new sewer, to . serve the area.
7.5 Emergency Operations
The City of Tukwila's. objective, is to - provide and support effective planning, _ disaster
management, and education services to enable citizens and employees of Tukwila to prepare for,
respond to, and recover from an emergency. The Public. Works Department has in place an
"Emergency Action ,Plan that outlines,; procedures to protect the City's infrastructure. , The
Emergency Action Plan identifies potential threats or hazards that may jeopardize the. City's
sanitary sewer system and is Available from the City. Some key,features are described below.,
z„
7.5.1 Emergency, Telephone Numbers
The City maintains ' a sewer emergency response crew on 24 -hour call. ° This .crew is available to
answer any emergency=- that may occur within the system and has :immediate- response
responsibility. This would include, but not be limited to, lift station alarms, sewer backups, and
forcemain blockages. The City maintains the following telephone numbers to allow the public to
notify the repair crews:
• During Business Hours: 443 -1860
• After Business Hours:. 911
The lift station alarms are monitored by computer in the City's Maintenance Facility during .
normal working hours. After hours, the alarms are monitored by the sewer computer alarm
system. If an alarm is sounded, the system dials the sewer crew at home, to respond to the
problem. The police dispatch is the last back up on the call out system.
System Vulnerability
Tukwila's sewer system is comprised of individual drainage basins that convey wastewater to
King County WTD's sewer . interceptors. In the event of a natural or manmade disaster, the
system has the following vulnerabilities to either loss of service or to pollution of the
surrounding environment.
• Treatment and Disposal: The City has an agreement with King County WTD for treatment
and disposal of all of the wastewater collected in the system. King County WTD has full
responsibility to ensure that the wastewater is properly treated prior to disposal. An
interruption of treatment service would result in discharge of untreated wastewater to Puget
Sound.
• Sewer Mains, Trunks, and the King County WTD Interceptors: Any pipeline is subject to
clogging and, under certain circumstances, the sewer pipe can break. Clogging of the sewer
creates backups in manholes and in severe cases these backups can progress back to customer
Operations and Maintenance 7-5
City of Tukwila
DRAFT
properties. Pipe breaks due to settlement, deteriorating pipe or other causes will pollute the
groundwater and result in excessive infiltration and inflow.
• Lift Stations: .The City operates eight lift stations within the sewer collection system. Failure
of a lift station would cause sewer backups in the system in the area of the lift station. The
City has recently modified a portion of the lift stations by installing 'bypass piping
connections. These 'connections allow the City to use their portable pump` to lift the
wastewater 'in the event of an emergency.. .
• Electrical Power: Power is provided to the -area by Seattle City Light and by Puget Sound-'
Energy (PSE). PSE has an extensive power 'distribution grid' in ,the Tukwila area and
electrical power can be supplied from many directions. Loss of power would shut down •
pump and control operations resulting in the conditions described above Historically, the
City has not experienced regular or extended power outages. The City maintains a backup
generator in the event of a power failure: ° All stations that are rebuilt receive, onsite 'generator
sets.
• Personnel:; Sewer system personnel are available to respond to emergency calls and have the
capability to perform minor repairs and emergency operations as required to 'sustain sewer
service: . .
• Supplies and Spare Parts: The City maintains a small inventory of spare parts that are normal'
for operations and emergency repairs. In the event of :a major catastrophe, the City would,
have to procure necessary spares from suppliers and reduce the level of service to consumers.
• Communications:: The City -uses Nextel radio - phones to keep in contactwith the field crews
during normal' working hours. After hours there are maintenance' crews on. call that . can be
contacted by the Police Department Dispatcher. A. radio system serves as backup to the
phones..
7.6 Safety
The Tukwila Public Works Department prides itself on having a keen sensitivity to the needs and
concerns of the community and their employees. To meet some of those needs the Public Works
Department works as a partner in the development of safety programs and awareness for all
utility employees. This has been accomplished by the implementation of an "Accident
Prevention Program" and can be obtained from the City.
Additionally, the Public Works Department maintains safety records for every employee and
monitors renewal dates. New employees are issued proper safety equipment particular to the job
assigned, and equipment is replaced with new as required. Each section of Public Works has an
assigned safety representative to help manage the program. Department and individual divisions
within the organization hold monthly safety meetings as well as on -site safety briefings before a
major project is undertaken. Particular emphasis is placed on the following topics:
• Confined space entry;
• Trenching and shoring;
• Chlorine safety;
• Heavy equipment operation
• Use of personal protection gear;
• Flagging;
• First Aid/CPR;

7.7 Design and Construction Standards and Specifications
Chapter 8 of- the' City's Development Guidelines and Design and Construction Standards
addresses ;:sanitary sewer design ' and construction standards. The Tukwila Public Works
Department conducts all construction of sanitary sewers and appurtenances in accordance with
this document and WSDOT /APWA standard specifications.
7.8 Supplies and Equipment
7.8.1 Standby Power. Generator
The City has one standby generator available for use at any site within the service area. It is an
80 -KW trailer- mounted diesel generator and is located at the Maintenance Facility.
7.8.2 Spare Parts
The Public Works Department keeps an inventory of commonly needed parts as well as
emergency supplies at the Public Works yard and stockroom. The City's supply department
tracks the inventory and orders additional supplies as required. The City keeps critical spare
equipment in stock. Large non - emergency items are purchased on an as needed basis.
7.8.3 '. Tools and Equipment
Smaller commonly used tools and equipment are carried in the employee's trucks or are readily
available from the stockroom. Tools and equipment such as pumps, small compressors, portable
generators, pressure washers, and power tools are available from the stockroom. .Larger,
infrequently used items are rented from various equipment rental companies located in Tukwila.
7.8.4 Heavy Equipment
The Public Works Department . owns heavy equipment such as dump trucks, rollers, boom truck,
forklifts, backhoes, and vactor units. If necessary, larger equipment is leased or rented on an
as- needed basis from local suppliers. The City's maintenance and construction crews have
personnel trained and experienced in heavy equipment operation.
7.9 Records and Data Management
The City of Tukwila maintains the following records for efficient management of the sanitary
sewer system.
Operations and Maintenance 7.7
MR I
City of Tukwila
DRAFT
• Customer Accounts: The City maintains records of each sewer account detailing sewer use
and any problems or complaints registered. _
• King County WTD Records: All reports on wastewater treatment charges and status
King County WTD are kept on file.
• Maps: A Comprehensive Sewer Plan Map of the full system is maintained by the City for
informational purposes. This map shows all proposed improvements and upgrades required,
all piping, manholes, clean outs, lift stations, .forcemains and; sewer trunk lines.
• As -Built Drawings: The City, maintains a comprehensive file of all as -built drawings of the
system improvements as they occur. These drawings show the location of side sewers in
many cases. and locate all other: piping as constructed..
• Pump Maintenance Records: The City keeps all lift station pump manufacturer maintenance
and technical information on file to .include but not be limited to: pump run tinie records,
maintenance, schedules, maintenance performed, repairs 'performed, problems. _encountered,
and any other information noted during the regular maintenance checks of the lift stations..
7.10 Maintenance Improvements
The _Public Works Department sewer operations and maintenance staff appear to possess or be
able to access all of the equipment and supplies ..required to adequately., .perform the
responsibilities assigned.
The lack of sufficient -labor to adequately address the many responsibilities of sewer operations
and maintenance was a recurring issue during this analysis.
An analysis of the Sewer Operations and Maintenance work programs of the .City of Tukwila
Public Works. Department was conducted to determine the adequacy of existing staffing levels.
The work production rates of existing O &M crews in performing a wide range of specific O &M
tasks related to pipeline, manhole and pump station maintenance were quantified. Unit rates of
work that can reasonably be accomplished per full time labor equivalent (FTE) were developed
and used to project the sewer O &M labor requirements of the Public Works .Department.,
Currently there are 3.5 FTE assigned to the sewer function. The projected requirement is 5 FTE,
or an increase of 1.5 FTE for sewer maintenance and operations activities.
It is recommended that the Public Works Department sewer Operations and Maintenance staff be
augmented by 1.5 FTE. This additional staff time would be devoted, in part, to implementing a
grease interceptor inspection program.

8.1 Identification of Recommended System Improvements
A number 'of system improvements have been identified during the completion of this`plan` The
development of the specific improvements has beendcribedin*heappropriate chapter.. .This
chapter combines the various improvements identified "into "a'single'listing that can be prioritized
and scheduled.
In addition to those :. improvements identified during SSP preparation, City operations personnel
have identified new facilities or facilities that require replacement. These facilities have been
included in the Capital Improvement Plan,
8.2 Improvements
A listing of improvements to Tukwila's sewer system has been created. through the combination
of two-separate sources. These sources include:
• A list of capital improvement projects provided by the City of Tukwila that are the process of
design or are currently being proposed, for the 2005 -2010 Capital Improvement Plan,
• A list of additional projects identified during the sewer analysis evaluation of the Tukwila
sanitary sewer system.
The two sources have . been combined into Table 8 -1 showing= project ' description, year of
construction, and estimated project cost.
Construction costs for new sewer line and manholes in the Capital Improvement Plan discussed
in the Comprehensive Sewer Plan were based on a $ /inch diameter of Pipe /foot. This` cost was
calculated from a collection of bid costs for similar projects in Washington State. The total bid
cost reported was divided by_the length and diameter of pipe to obtain the unit cost. Costs for
manhole replacement and new wet wells were likewise based on reported bid costs.
Construction in roadways in Tukwila is more expensive than the typical construction, thus costs
in the CIP were increased by approximately 20 percent to account for nighttime construction and
the additional traffic control required.
The costs listed in the CIP are Project costs which include construction costs discussed above
plus Sales tax (8.3 %), design and construction engineering (20 %), Administrative costs (10 %),
Contingencies (20 %), and permitting (5 %).

Section 9
Financial Plan
9.1 Introduction
The effective implementation of a Sewer System Plan (SSP) is dependent upon accurately
developing a document and recommendations that can-be financially supported by the utility; will
meet State and local regulatory requirements; and provides the flexibility to deal with unforeseen
changes.
This section presents a finaricialplan that reviews the sources of funds (revenues) and applications
of funds (expenses) for the City of Tukwila's (City) sewer system. The financial plan °includes
projected operatingand capital_costs ofthe system for the six -year time horizon of 2005 -2010. The
revenues and expenses used in the financial plan were obtained from the City's 2004 Budget in
conjunction with historical expenditure : information. ; The capital .Costs contained: within the
financial plan utilize :the Capital Improvement -Plan` (CIP) presented in Section 8 of this Sewer
System Plan. The results of the financial plan outline the annual operating and capital needs of the
sewer system and determine- if the sewer revenues are sufficient to cover costs over-the projected
time period. This analysis does, not provide a=-detailed review of cost of .service or rate. designs:
However, the City may consider performing a rate study independent of this planning document to
address equity issues.
9.2 Past Financial History
The past six years of financial information for the sewer utility were evaluated to gain an
understanding of the past performance of the utility, and at the same time, gain perspective of the
current financial status of the City's sewer utility.
Table 9 -1 is a summary of a six -year financial history (1998 - 2003) for the City's sewer utility.

As Table 94 illustrates, the utility is showing an overall positive cash flow during the historical test
period..' . However, the balances have been : declining ' over the five year period. The available
balances are.used for.capital improvements and/or reserved for future capital needs. The utility has
historically -funded '.a substantial level . of capital improvements through rates: Based on the
historical :. review, it appears that the level of rate funding is declining. Target levels for funding
future capital improvement projects is discussed later in this section.
9.3 Development of the Financial Plan (Revenue
Requirement)
A financial plan is `developed to determine the City's ability to meet its capital improvement and
operating needs over a projected time period. In developing the financial plan, fund balances and
reserve levels were also analyzed. The City's financial plan was developed to review the projected
revenues and expenses of the sewer system for 2005 -2010. The City's 2004 Budget was used as a
base while future years were escalated by applying factors for inflation and growth.
9.3.1 Sources of Funds
The first component of the financial plan is a review of the sources of funds for the sewer utility.
The different revenues or sources of funds received from operations are:
• Rate revenues - sewer sales to customers;
• Other revenues - service repairs and inspection fees; and
• Interest Revenue - interest earnings on fund balance.
Projections for future year revenues were developed by applying a projected growth rate of 1% to
the 2004 budgeted rate revenue. Other miscellaneous revenues, including investment interest and
other revenue, are projected to increase approximately 2% to 3% per year through 2010.

DRAFT
The rate revenues of the City come from retail sales to residential and commercial industrial
customers. Rate revenues are projected to be $3.6 million in 2005. This is an increase of $340,000
investment interest. Other revenues increase over the six year projections, reaching appro ximately
$27,000 by 2010.
The total revenue available to offset, the ,operating and capital requirements of the sewer system is
approximately $3.7 million in 2005, increasing to $3.9 million by 2010.
9.3.2 Application of Funds
The second component'of the'financial plan is a review of the applications of funds. In developing
the financial forecast, four main cost components were reviewed:'
• Operations and Maintenance (O &M);Expenses
• Taxes andTransfer Payments
is Debt Service
• Capital Improvements Funded From Rates
Operation and Maintenance Expenses
Using the 2004 Budget as a starting point, expenses were escalated by assumed inflationary rates to
obtain projected'°•costs.' Escalation factors range from employee benefits; at an: average • annual
increase of 12 %, to miscellaneous items and materials and supplies at 2 %. Labor is 'escalated, at 4% -
and purchased wastewater treatment (King County WTD) at 9% in 2005 based on a projected fee
increaSeT Purchased 'wastewater treatment is also escalated at 3% every other year after 2005 to
estimate 'possible future rate 'increases: Detailed escalation factors are provided in Appendix H,
accompanied with a copy 'of the financial plan.
Two 'exceptions : to the budgeted labor costs were included in the financial plan. There are • an
additional 0.5 full-time •equivalent (FTE) utility worker in 2005 and a 1.0 FTE utility worker in
2008 for operation and maintenance of the sewer system. During the time period, salaries • and
benefits increase from $263,910 in 2005 to $459,836 in 2010.
It should be noted that no other program. cost increases, above budget year -2004 figures, were
assumed as part of the projected costs. Operation and maintenance expenses ranged from
approximately $3.8 million in 2005 to about $4.3 million in 2010, including taxes and transfer
payments.
Taxes and Transfer Payments
The sewer system currently has tax obligations to the State in ,the form of an excise tax, the State
Public Utility Tax. The tax is calculated at 3.852% of the sewer utility rate revenues. For 2005, the
taxes /transfer payments total approximately $43,000 and increase to about $46,000 by 2010.
• Projected taxes for the period assume constant tax rates over time.

Debt Service
There is currently one outstanding loan obligation for the. City's sewer system. It is a 2004 Public
Works Trust Fund loan for the Allentown/Foster Point capital 'improvement project. During this
period, partial payment begins in 2005 and annual payments of $165,000 are scheduled from 2006.
to 2010. A revenue bond is also projected for the Allentown /Foster Point project in 2006: During
this time period, partial payment begins in 2006 and annual payments of $146,000 are scheduled
from 2007 to 2010: The combined' debt service on the existing and projected future debt is
approximately $311,000 by 2010.
The financial plan developed for the City assumes that one new revenue bond issue will be required
through 2010 to meet the capital needs identifiedas part of this plan.
Meeting debt service coverage requirements is an important financial indicator for well managed
utilities. Debt service coverage is a financial measurement of an entity's ability to repay:debt. A
debt service coverage ratio is a comparison of net income before debt service payments to the total
debt service on revenue bonds. Typically, utilities must meet a 1.25 coverage ratio test, but
coverage ratio may vary based on existing bond covenants. After calculating the proposed rate
adjustments, the City meets this requirement through the test period. (Additional details regarding
the proposed rate adjustments are included in Section 9.4, Summary of the. Financial Projections).
The City should monitor this ratio during its future financial evaluations.
Capital Improvement Projects from Rates
Capital improvement projects are related to the infrastructure of a utility. Capital improvement
projects are generally divided into two categories: capital improvements related to , renewal , and
replacements of existing plant and depreciated facilities, and growth related projects; including
system expansion and upgrades to accommodate new customers.
The City capitalizes a portion of staff time and benefits related to those staff working on capital,
projects. , In addition, there are planning and construction projects included within the capital
component of the financial plan. The financial analysis conducted for this plan has incorporated the
capital projects outlined in Section 8 of this Plan. These projects have been allocated by year in
order to quantify the annual capital requirements for the projected time period. For 2005 to 2010,
the identified capital improvement projects total $8.4 million. It should be noted that $4.9 million
of the total is for the Allentown/Foster Point Sewer System.
The majority of the funding for the capital projects will come from the use of a new low interest
loan and a new revenue bond. The combination of the loan and revenue bond totals $4.3 million.
The remaining funding will come from a combination of reserves, contributions and investment
interest, $2.2 million.
Additionally, this financial analysis assumes that the City will fund renewals and replacement
projects at a fixed amount equal to or greater than the annual depreciation expense of the utility.
Utilities should strive to replace the annual depreciation expense each year in order to maintain their
system at an appropriate level. The City's records reflect that the annual depreciation expense for
the sewer utility in 2003 was approximately $223,000. In 2005, funding for replacement capital is
established at $250,000 and continues to grow $50,000 per year through the test period. In 2010,

the funding totals .$500,000. Thus, the City will have sufficient funds available to maintain its
system at an appropriate level.
The capital' analysis 'assumes that any additional funding beyond what is necessary to meet the
annual capital requirement's will be placed into the working capital reserve for future capital needs:

When interpreting the results of Table 9 -2 it is important to understand that the "Rate. Adjustment
As A % of Rate Revenue" is cumulative. That is, any rate adjustments made in previous years
would reduce what is required in the following years. It is also important to keep in mind that the
model assumes expenses are completely expended within each year Typically, utilities receive
additional revenue and often actual expenditures do not total 100% of budget appropriations.
Therefore, the city has a number of options for deferring the adjustment until the latter part of the
test period. Those options would include adjusting capital improvement timing, increase reserve
funding for capital improvements, reducing operating expenses, and closely monitoring additional
revenue or increased growth beyond the 1% assumed.

DRAFT
The results of Table 9 -2 indicate that the existing sewer rates with proposed rate adjustments are
sufficient during the time period under review. With existing rates not meeting existing operation .
and maintenance and debt service requirements of the utility, rate adjustments are required. The
proposed level of rate adjustments ensures that the sewer system has sufficient funding for adequate
operations . and maintenance of the system as well as proper funding of capital improvements., the
City should continue to review the utility's financial position to confirm that such rate increases are
necessary and to determine if additional funds . may be required due to unforeseen growth and
capital purposes.
It is important to note that the financial plan presented in this section is predicated upon an assumed
level of growth' on the system '(1.0% per year), and assumptions related to inflation. Should this
growth increase, slow down, or not occur, the level of rate adjustment required will be affected.
Likewise, if costs escalate faster or slower than indicated in this plan, the rate adjustments needed
would also be affected.
9.5 Reserve Level
A key indicator of financial health and viability is ..a utility's reserve levels. Maintaining adequate -.,
reserve levels is important for stable fiscal management of the utility. A discussion of the utility's
reserve is provided below.
Industry standards (American Waterworks Association — AWWA) recommend that utilities
maintain working capital reserves at a level adequate' to handle unexpected occurrences, including
unexpected 'cash flow fluctuations. A balance for an O &M reserve, or operating reserve, is
recommended to be a minimum of 45 days of operations and tax expense. For the City, that
minimum balance would average approximately $480,000 in the first half of the review period, and
increasing to about $520,000 by 2010. The City entered 2004 . with a reserve balance of $1.7
million in working capital. Reserve balances are stable throughout the test period due to capital
needs being less than available funding. The 2010 ending balance is $1.0 million. This balance
will provide the City with flexibility in meeting future capital requirements.
The reserve review indicated that the . City has adequate reserve funding to meet unanticipated
obligations and general operating fluctuations. The City could improve upon and clarify their
financial planning goals by establishing financial policies that define the appropriate reserves to
establish and identify a target or minimum funding level for each reserve.
9.6 External Sources of Funds for Capital Projects
The City has the ability to apply for grant and loan funds available to public entities for sewer
system projects: The City has been successful at obtaining a number of low - interest loans, as
described earlier under the debt service section. Table 9 -3 provides a summary of the contacts for
various funding agencies. These sources rarely provide full funding of a construction project and
the City would need to supplement any of these funds with matching funds to .meet eligibility
criteria and to ensure that implementation of the recommended capital improvement projects can
•
occur.

A brief description of these :funding sources :is provided below.
Department. of Ecology(Centennial Clean Water Fund & State, Revolving Fund),
The Centennial Clean Water Fund (CCWF) is available to local governments for measures to
prevent and control water pollution. Both grants and loans are available on a yearly funding cycle.
CCWF is the largest State grant program for water quality projects. It provides grants forplanning,
design, and construction of facilities and other activities related to water quality. The primary focus
of the program. is ..pollution prevention and funding projects . with a quantifiable water quality
benefit, such as protecting a source of water ,supply. Funding ,from •this program is not available to
provide.excess capacity, but must be used to meet existing residential needs. Interest rates are 0.5%
for loans up to five years while those over five years, but less,than, 20 years have a 1.5 %, rate. Grant
funding of 50 %;to 75 %o.of a project is available depending on the type of project.
Another source of funding for local governments from the Department of Ecology (Ecology) is the
State Revolving Fund (SRF). Loans are available on a yearly funding cycle for planning, design,
and construction projects associated with wastewater treatment facilities. Eligible projects may
consist of secondary treatment, advanced treatment, infiltration/inflow correction, sewer system
rehabilitation, collector and interceptor sewers, storm sewers, and combined sewer overflow
correction. Interest rates are 0.5% for loans up to five years while. those over five years but less
than 20 years have a 1.5% rate. .
Public Works Trust Fund
The Public Works Trust Fund (PWTF) loan program is set up by the Legislature to assist local
governments with funding for different types of public works projects. The projects can include
sanitary sewer systems, water systems, streets, roads, and drainage systems. The emphasis of
allocating funds is for replacement and/or repair of existing systems. Specifically, funds are granted
to rehabilitate or replace existing systems serving an existing population. Loans are issued at up to
2% interest rate for a maximum term of 20 years for applications requesting 95% project funding.
The interest rate decreases to 0.5% when applicants provide at least 15% of the project funding.
The debt service coverage ratio is not calculated on the PWTF loan.

Infrastructure Assistance Coordinating Council
Many programs exist with funding available for sewer utility capital projects. A key resource in
identifying such programs is the Infrastructure Assistance Coordinating Council (Council).-The
Council is comprised of state and local organizations whose function is to' provide funding. for
infrastructure repair and-development. The purpose of the Council is to assist local 'governments, in
coordinating funding efforts for infrastructure improvements. This is an important resource as the
Council will be aware of any new funding opportunities that may arise.
While the above list of possible grant and loan opportunities for the City is not exhaustive, it does
highlight the most probable outside funding sources, excluding revenue bonds, available to the City
for its sewer capital improvement needs. _
Revenue Bonds
Revenue bonds are another external source of funding for capital projects. The sale of .revenue
bonds is the most common source of funds for construction of major utility improvements.. Sewer
fees and charges are the main source of funds-for debt service (principal and interest) payments. A
key benefit of revenue bonds is the exemption of interest paid on them from federal income taxes.
A determination of the utility's ability to repay debt is an important consideration. To assist with
the determination, a debt service ratio (see Application of Funds — Debt Service) is calculated and
the utility's finances are reviewed. The financial review generally includes both current and past
budgets, financial statements, budgetary practices and polices, and reserve level balances.
Internal Funding Sources
Internal fiuidirig sources available to offset capital costs include contributions received from new
sewer connections and existing reserves. New sewer connections are assessed a charge as a way to
recover 'part 'or all of the cost of building the infrastructure. The intent is that all new 'system
customers ' will ' `pay an requitable share of ' the cost of the system ;improvements needed to
accommodate growth.' Existing reserves can also be used for capital projects when costs can not be
entirely financed by current revenues. An advantage of using existing reserves includes the
forgoing of additional annual debt service payments. More typically, utilities use a mix of current
funds and bond proceeds to fund larger capital projects.
9.7 Review of the Existing Sewer Rates
There are various "generally accepted" sewer rate structures that can be used to establish or develop
rates. The initial starting point in considering a rate structure is the relationship between fixed costs
and variable costs. Fixed costs are generally collected as a fixed charge on a monthly basis (e.g.
$5.00 per month/account). This charge may be called by various names (e.g. customer charge, base
charge, etc.) but in all cases, it is intended to collect those fixed costs that the utility incurs.-
•
Variable costs are primarily based upon the amount of wastewater flow. Sewer customers are
typically billed a variable charge on the actual amount of water that each customer consumes. Since
water that is used by the customer is not all discharged to the sewer system, the sewer service
charges are based on an estimated percentage of the metered water volume that is returned to the
sewer, or "flow factor ". For residential customers, some utilities monitor water use during the
winter months to determine how much of the consumed water is returning to the sewer system.
JAWS City Plan 8-8
City of Tukwila
•
During the winter months, water is primarily consumed for household use rather than outdoor use,
such as lawn watering.
The City's sewer utility has three customer classes: residential, multiple family, and
commercial /industrial. Currently, the City charges single and multiple family customers a flat rate
of $7.00 with no additional charge for consumption. Commercial and industrial customers pay a
minimum charge of $12.00 per month for up to 750 ccf of consumption plus $12.00 per additional
750 ccf or fraction thereof. In addition to the City charges, a City King County WTD rate is passed
on to customers for the collection and transmittal of the City's wastewater to King County WTD for
treatment and disposal. Single - family customers are charged a flat rate of $25.60. Multiple family
and commercial/industrial accounts pay a minimum of $25.60 per meter for up to 750 ccf of
consumption plus $25.60 per each additional 750 ccf or fraction thereof. Sewer service rates in
effect as of January 2005 are presented below in Table 9 -4.

A majority of the utility's revenue (75 %) comes from the commercial customers. An additional
16% comes from multi- family and the final 9% from the single - family residential customer class.
As related in the Summary of the Final Projections section, the City is considering proposed rate
increases in 2006 through 2010. The rate increases will assist the City to meet the utility's
operating and capital needs.
•
The conceptual rate review undertaken indicates that the City's rates are in line with current
industry trends and attempt to capture the cost differential to serve customers with varying usage
characteristics and facility requirements.
9.8 Overview of Future Sewer Rates
Based upon the results of the financial analysis, the City will require significant annual rate
adjustments in future years to meet the on -going needs of the sewer utility system. Completion of a
comprehensive rate study would assist the City to identify if any rate structure changes are
warranted based on the City's goals, objectives and the manner in which costs are incurred. The
City may also wish to conduct a cost of service study in the near future to verify that the rates
charged to residential and commercial customers are cost -based. A cost of service study also
includes a review of the current rate structure and provides alternative approaches that meet the
goals and objectives of the City.

9.10 Summary
The financial plan results presented indicate that the sewer rates with the proposed adjustments in
2006 — 2010 will adequately fund the O &M, capital, and debt service requirements. The rate
adjustments will assist the City in the management of the utility by funding operations, capital and
reserves at a sufficient level. The City has been proactive in its financial management in the past
and continues to demonstrate its commitment to adequately fund the utility's levels of operations,
capital and reserves. Continued fiscal management will enable the sewer utility to operate on a
financially sound basis.

9.9 Neighboring Utility Rate Comparison
The City requested a comparison of the City's sewer utility rates with rates of surrounding utilities.
In developing any rate comparison, it is important to understand that such comparisons are not
"apple to apple" comparisons. We have found that such comparisons do not account for differences
in customer makeup, capital funding mechanisms, treatment plants, etc. Each of these factors can
radically alter rates, and thus any rate comparison. Given that understanding, a simple comparison
between these neighboring utilities for single - family residential and commercial customers was
developed.
A bill comparison was developed for residential customers of six surrounding jurisdictions and
Tukwila's current rates. As noted earlier in this section, Tukwila's current rates are shown not to be
adequate through the review period of 2010. As shown in Exhibit 9 -1, the base meter charge is
identified for comparison purposes. The bill comparison considered a single family, residential
customer with no additional charge for consumption. Based upon this review, it appears that the
City's rates are the lowest of other neighboring utilities for the single family, residential rates.
Exhibit 9 -1
Monthly Residential Rate Comparison

Similarly, a comparison for commercial customers was developed. This analysis assumed the
monthly base meter charge plus consumption charge per additional 750 ccf. This comparison is
provided in Exhibit 9 -2. Again, it appears that the City's rates are within the lower range of other
neighboring utilities for the commercial rates.

In the future, the City expects to add four new areas to its service area. These four areas consist
of eight sections which were condensed into the four areas for planning purposes. The precise
timing of adding these new service areas is dependent on a variety of factors and is not fully
known. Timing assumptions have been made for this SSP based on the best available estimates
from the City. The four new areas include:
• North Septic Area: This includes the two most northern septic sections, as well as an area
currently served by Val -Vue Sewer District known as the Boeing access Area.: ' For planning
purposes, portions are scheduled to be sewered beginning in 2011.
• SE City Comer: This area will be taken over from the Citykof,Renton. Assumption of this
area is assumed to begin in the 11th plan year (2015), which coin cides with the timing for this
area used in the Water System Plan.
• South Septic Area: This area includes the three most southerii'selitic sections. Assumption of
these areas is assumed to begin in the 16th plan year (2020).
• South Annex: This area is unsewered and is outside the current city boundary, but is
designated as a Potential Annexation Area and ` is. therefore expected " to be annexed.
Assumption of this area is assumed to begin in the 11th plan year (2015), which coincides
with the timing for this area used in the Water System Plan.:" The Tukwila Valley - South
(Drainage Basin No. 14) proposal, described in Section.2.3,smay affect the development of
sewer services in this area.
2.3 Drainage Area Descriptions
Because of the many annexations that have occurred in the past, the assumption of sewer service
from other providers, the topographic challenges for sewer system design and construction, as
well as development pressures, Tukwila's existing sewer system is particularly complex. The
existing sanitary sewer service area is composed, of 24 separate` drainage basins, delineated on
Exhibit 2 -2. A general description of each basin is presented below. Table 2 -1 summarizes the
status of the City's existing sewer service by neighborhood (see Exhibit 1 -1); drainage basin, and
service provider. Areas that the City expects to add to its service area (Exhibit 2 -1) are also
shown in the table.

2.3.1 Drainage Basin No. 1
Drainage Basin No. 1,is in the vicinity of the Gateway Drive area in the north central part of the
City. Its northerly and easterly boundaries follow the 1988 city limits. Its southerly boundary is
in the vicinity of 48th Avenue South. A portion of the drainage area is west of Interurban Avenue
South.
Land use in Basin No. 1 is largely commercial. The area is served by two 8 -inch gravity mains
in the Gateway Drive loop that connect to two 18 -inch Tukwila mains, as well as 12- and 18 -inch
gravity mains along 48th Avenue South. The 18 -inch Tukwila lines and Tukwila's 12 -inch line
410 connect to the 54 -inch Tukwila trunk sewer located along Interurban Avenue South.
/gees Description of Sanitary Sewer System 2-5
City of Tukwila
DRAFT
Tukwila's 12 -inch main along 48th Avenue South also receives wastewater from Drainage Basin
No. 20 via a 4 -inch force main from the Burlington Northern Santa Fe Railroad (BNSF RR)
pump station located across the Green River. Pump Station No. 9 serves the REEFF
Management Group development and discharges directly to the King County WTD trunk line via
a 6 -inch force main.
2.3.2 Drainage Basin No. 2/18
Drainage Basin No. 2/18 (Basin designation is from the 1999 Addendum) is also in the north
central part of the City. It is bounded on the north 'and east by the Green River and on the south
by South 154th Street. The westerly boundary is irregular, generally following 55th Avenue
South, 57th Avenue South, South 147th Street and the easterly boundary of I -5 in the northern
most reach. The basin is mostly residential with some commercial uses.
Most of the basin is served by 8 -inch gravity mains. The south end sewers drain to Tukwila's
Lift Station No. 7 located north of South 147th Street and adjacent to Interurban AvenueSouth.
Lift Station No. 7 discharges via a 6 -inch force main to an 8 -inch ,gravity main located in
Interurban Avenue South, where it flows to King County WTD's 54 -inch trunk line and
subsequently to King County WTD's Interurban - Pumping Station. Ari old sanitary sewer
overflow to the Green River at the far south end of the City's sewer system has been abandoned
and plugged. •
A 12 -inch gravity main also serves the south end of Basin No. 2/18. This line runs east of and
parallel to Interurban Avenue South. It ultimately discharges to the King County WTD trunk
line below the Interurban Pumping Station. The remainder of Basin No: 2/18 drains by gravity
directly to the King County, WTD trunk line and the Interurban Pumping Station.
2.3.3 Drainage Basin No. 3
Basin No. 3 includes Fort Dent Park and the low -lying green belt areas along 'the Green River.
Its boundaries are, highly- irregular, but generally, are as follows: The southern - and easterly
boundaries are I -405 and the city limits, respectively. The Green River boundithe northernmost
reach of the drainage area and Interurban Avenue South bounds a small reach in the southwest
section of the basin between I -405 and the Green River. There is a small meander of the Green
River in the southern part of the drainage area.
The area within the Green River meander drains by gravity to the City's Lift Station No. 5.
From there it is pumped via a 4 -inch force main across the river to an 8 -inch gravity main where
it then flows by gravity to Tukwila's Lift Station No. 6. Lift Station No. 6 pumps wastewater via
a 4 -inch force main to an 8 -inch gravity which drains to the treatment plant connection. In the
future, it is intended that the force main will be revised so that lift station 5 will flow to
Interurban'.
2.3.4 Drainage Basin No. 4
Drainage Basin No. 4 is bounded generally by South 147th Street on the north, 57t Avenue South
on the west, I -405 on the south and on the east by the irregular boundary between I -405 and
South 147th Street, as described for Drainage Basin No. 2/18. The basin includes single and
multifamily units as well as the Tukwila City Hall and several restaurants and office buildings.

Basin No. 6 is a small basin just to the west of I -5 and north of SR 518. It is bounded on the
west by 51! Avenue south and on the north by South 151st Street. Sanitary sewer service
consists of 8 -inch pipelines that discharge directly to King County WTD lines located within the
basin.
2.3.7 Drainage Basin No: 7
Basin No. 7 is just south of SR 518 and west of I -5. Tukwila International Boulevard forms its
short, most westerly boundary and its southern boundary traverses South 160th Street, South
164th Street and South 168th 'Street. Service to this drainage area is .provided'by Val -Vue Sewer
District. However, a significant area within the basin is on septic tanks and will potentially be
sewered by the City (see'Exhibit2 -1).
2.3.8' 'Drainage Basin No. 8
Basin No 8 covers the Southcenter Shopping Center. It is bounded on the north by I-405, on the
west by I -5, on the south by Strander Boulevard and on the east by the Green River. Generally,
wastewater is conveyed by 8 -, 12- and 14 -inch gravity pipelines to Tukwila's Lift Station No. 12
located at the intersection of Strander Boulevard and Andover Park West. A private lift station
discharges into the City's conveyance system in the northwest corner of the basin. Lift Station
Number 12 discharges into the King County WTD interceptor at the ' Strander Boulevard
• intersection.
2.3.9 Drainage Basin No. 9
This basin is east of Basin No. 8, across the Green River. It is bounded generally by the river on
the west, the city limits on the east and I -405 on the north. The, south boundary is just south of
Strander Boulevard. The basin serves light industrial customers: Wastewater flows by gravity
via 8 -and 12 -inch pipelines directly to King County WTD's 36 -inch interceptor that leads to its
East Plant.
2.3.10 Drainage Basin No. 10
Drainage Basin No. 10 is east of the Green River. It is bounded generally by the southern
boundary of Basin No. 9 (extension of Strander Boulevard) on the north, the river on the west,
South 180th Street on the south and the city limits (BNSF RR right of way) on the east. It is
comprised of light industrial uses. Sewer service consists primarily of a 12 -inch pipeline that

flows by gravity from the extension of Minider Boulevard (Costco Boulevard) to the 36 -inch
King County WTD interceptor along Strander Boulevard.
The lower portion of this drainage (below the extension of Minkler Boulevard) has been
designated by the City as SE City Comer (see Section 2.2). It is currently served by the City of
Renton. For planning purposes, it is projected that Tukwila will assume responsibilities for
sanitary sewer service in SE City Comer in 2015.
2.3.11 Drainage Basin No. 11
This basin is located southeast of the Southcenter Shopping Center. It is bounded by Strander
Boulevard on the north, the Green River on the east and Minider Boulevard on the South. The
western boundary is roughly halfway between Andover Park West and Andover Park East.
Basin No. 11 is made up of largely commercial and light industrial uses.
Wastewater from customers in the southeast corner of the basin is conveyed by_ 8 -inch gravity
mains to the City's Lift Station No. 3 located near the City Shops. Lift Station No. 3 pumps
wastewater via a 4 -inch force main to an 8 -inch gravity line in Andover Park East that then flows
north to a 10 -inch main and hence to the King County WTD interceptor on Strander Boulevard.
2.3.12 Drainage" Basin No.' 12
This basin is located directly south of the Southcenter Shopping Center, between Strander and
Minkler Boulevards. On the east, Basin No. 12 is adjacent to Basin, No. 11. The ,western
boundary of Basin No. 12 starts at a point on Minider Boulevard that is about 1,200 feet west of
Andover Park West. From this point the boundary line extends north for a distance of about
1,400 feet, where it then turns west to I -5. The basin consists of office buildings and commercial
and light industrial development. It is served by 8 -, 12- and 21 -inch sewers. Wastewater
generated in the area flows by gravity to the King County WTD interceptor on Strander
Boulevard.'
2.3.13 Drainage Basin No. 13
Basin No 13 is the largest in the City's sanitary sewer system. It serves all of the southern area
of the City below Minider Boulevard to the Green River on the east and to the vicinity of South
Glacier Street on the south. The westem boundary is I -5. Uses in the area include commercial,
light industrial, and heavy industrial. The Shasta Bottling Plant and ,CostCo Food Plant are
located in this basin.
Conveyance in Basin No. 13 consists of 8 -, 10 -, 12 -, 15- and 18 -inch pipelines. Lift Station No.
4 collects wastewater from the southeast corner of the basin and pumps it north across the Green
River via a 6 -inch force main to the gravity sewer system on South 180th Street. An old overflow
manhole to the Green River at South 180t Street has been removed.
The gravity system on South 180th Street and the remainder of the sewers in Basin No. 13 flow
by gravity to the City's Lift Station No. 2 located at the intersection of Minkler Boulevard and
Andover Park West. Lift Station No. 2 pumps wastewater to the 21 -inch gravity sewer along
Andover Park West in Drainage Area No. 12 that eventually flows to the King County WTD
interceptor in Strander Boulevard.

2.3.21 Drainage Basin No. 21
Basin No. 21 is immediately north - northwest of Basin No. 20. From the intersection of South
104t Street and East Marginal Way South in the northwesterly comer of the basin, the western
boundary follows the Green River to Tukwila International Boulevard: , From there it generally
follows SR 599 easterly, and then southerly to its intersection with Basin No. 20 at 42n. Avenue
South. At this point it turns north, again following a segment of the Green River (and :the
western boundary of Basin No. 20) to South 118 Street, where it turns east to I -5. It then turns
northwest along I -5 to its northern boundary:along South 104t Street.
Currently,' this basin is served largely by Val -Vue Sewer District. An area in the southeast
comer of the basin bounded by South 115th Street on the north, 42nd Avenue on the east, and East
Marginal Way South on the west and south is unsewered. It is one of the "North Septic Areas"
identified in Section 2.2 and shown on Exhibit 2 -1. For planning purposes, it is scheduled to be
sewered beginning in 2011.
2.3.22 Drainage Basin No. 22

west and south and the city limits on the north and east. Much of the basin is unsewered and is
identified as one of the "North Septic" areas on Exhibit 2 -1.
Existing service in those portions of the basin that are sewered consists of 8- and 12 -inch gravity
lines in several locations. There are two connections to existing 18- and 24 -inch pipelines
located in Martin Luther King Way.
2.3.23 Drainage Basins Nos. 23 and 24
Basins Nos. 23 and 24 are located on the east and west side of East Marginal Way,, respectively,
northwest of Basin No. 21. Most of the industrial and commercial customers in these basins are
served directly by King County WTD's 42 -inch trunk line in East Marginal Way.
2.4 Sanitary Sewer Facilities
This section provides information on Tukwila's main sewer facilities and key operating
considerations associated with these facilities.
2.4.1 Existing Lift Stations
The City owns and operates eight lift stations within the drainage basins described in Section 2.4.
Three additional lift stations are planned for the future. Table 2 -2 summarizes the location and
key features of each station. The lift station numbering system was recently revised by the City.
Table 2 -2 provides both the old and new numbers for each station.
2.4.2 Existing Collection Facilities
Between 1961 and 1991, the City's sewer system expanded rapidly through the creation of Local
Improvement Districts (LID's), developer extension agreements and the annexations that took
Description of Sanitary Sewer System 2 -10

place in 1989. By 1991, the system included over 140,000 lineal feet of 6 -, 8 -,10 -, 12 -, 15 -, 16 -,
18 -, 20 -, 21 -, and 24 -inch diameter sewer pipe with 470 manholes and eight lift stations. Since
that time, approximately 43,000 lineal feet of pipeline, 260 manholes, and one lift station have
been added to the system.
The City's existing sewer system serves approximately 4,035 acres in the drainage areas
described in Section 2.4. Over 80 percent of the collection system consists of concrete pipe, with
the remainder composed of 15% polyvinyl chloride (PVC) and 5% other materials.

2.4.3 King County WTD Facilities and City Connections
Major King County WTD facilities within the City's existing sewer service area include gravity
and force mains of various diameters,: the_ new Interurban Pumping Station, and the Renton
Effluent Transfer System (RETS). .King County WTD's East Plant is located outside of the
service area just to the east of Drainage Basin No 3.
One major (42 -inch diameter) gravity trunk line enters the City's service area at its northern
boundary with the City of Seattle and runs along East Marginal Way and Puget Sound Energy's
right of way to the Green River. From there, wastewater is pumped via two, parallel 12 -inch
force mains that cross the City and then run generally along the eastern city limits to King
County WTD's East Plant.
A second major trunk line begins as a 48 -inch pipe just north of South 118th Street (in the BNSF
RR right of way) and runs south to and across the Green River where it changes to a 54 -inch
diameter pipe. From there it runs adjacent to Interurban Avenue to the new Interurban Pumping
Station located at the intersection of Interurban Avenue and 57th Avenue South. Two 24 -inch
force mains transport wastewater from the pumping station along Interurban Avenue and under
the Green River to the East Plant.
The 96 -inch diameter RETS runs from the East Plant along the City's eastem boundary before
turning west and entering the City near the Interurban Pumping Station. From there, it runs
generally northwesterly adjacent to Interurban Avenue and along SR 599 to the City's
northwesterly limits in the vicinity of Tukwila International Boulevard and West Marginal Way.
The City has numerous connections with King County WTD trunk lines. The City has an
agreement with King County WTD for conveyance and treatment of the City's wastewater at the
East Plant, as described in Section 3.1.
2.4.4 Infiltration and Inflow
Both the 1991 Plan and the 1999 Addendum addressed the impact of infiltration and inflow (UI)
on conveyance facilities in the City's collection system. The 1999 Addendum noted that
estimates of existing flows showed that some basin interceptors were near capacity. Estimates of
future flows indicated that several others may exceed their capacity by the end of the ten -year
planning period (2009). As a result of these findings, it was recommended that the City (1)
initiate flow monitoring studies to document the actual extent of capacity problems, and (2)
investigate and reduce I/I problems within the collection system as required by King County
WTD.
In March 2005, King County WTD completed a study, entitled, Regional Needs Assessment
Report: Regional Infiltration and Inflow Control Program, King County WA. This report
identified conveyance system improvement projects and cost and included flow monitoring and
modeling for forecasting future I/I flow rates. This study provided a baseline for conducting
benefit and cost analyses of potential I/I reduction programs.
As part of this effort, King County WTD developed maps of 20 -year peak hourly 1/I flows for
areas served by King County's wastewater treatment system. Tukwila's wastewater conveyance

system is characterized as being subject to 20 -year, peak hourly flow rates of 1,100 to 3,550
gallons per acre per day.
The City has not experienced any conveyance problems, except at lift stations in the . Central
Business District (CBD) generally identified as Drainage Basins No. 4, 8, 11, 12 and 13. As a
result, the City identified the CBD as one of the critical areas for detailed sewer system modeling
and hydraulic analysis. The sewer system analysis performed for this , SSP . is presented in
Section 6.

Related Plans, Policies and Agreements
The City of Tukwila'sprogram to ensure a comprehensive and reliable. system for' providing
sewer service to its customers is embedded in -al larger network of plans, policies; and agreements
that address sewer service and land use both within the City and within the greater King County
area. This section provides a brief description: of =selected plans *policies, and'agreeinents that
relate to the Tukwila sewer system. This Comprehensive Sanitary Sewer Plan Update (SSP) is
consistent 'with -these' plans, policies; -, and ° agreements: Appendix `'B' presents ',checklists
demonstrating 'this' Plan's consistency with King County and Washington State Department of
Ecology planning requirements. '
3.1 ' Tukwila and King County WTD Treatment Agreement
Wastewater ,froin`,Tukwila is ',conveyed to; and :treated at the King County: WTD wastewater
treatment plant in Renton under an agreement between the-C4 and King: County WTD. This
agreement is found in Appendix C. King County WTD's fees are based on potable water sales,
since sewer flows are not mete red by either Tukwila or King County WTD. King County WTD
charges the Cit
g y $25:60 for every "Equivalent Residential Unit" (ERU) of potable water sold.
An ERU is the average amount of water consumed by a single family household: King County
WTD's system wide ERU is 750 cubic. feet.
3.2 Tukwila Sewer Ordinances.
City of Tukwila ordinances related to sewer "service are contained in Title 14 Water and Sewers
of the Tukwila Municipal Code. These ordinances cover subjects such as rates; and 'connection
policies. Appendix D 'contains all sewer- related Title 14 ordinances.
3.3 Tukwila Sewer Rates
Existing sewer rates are found in Title 14.16 and the Title 14 fee schedule of the Tukwila
Municipal Code. .These existing monthly rates are shown in Table 3 -1 below. Bills are paid to
the City of Tukwila; however, they contain one component charged by the City of Tukwila and
another component charged by King County WTD. Single family households pay a flat rate of
$7.00 for the Tukwila charge and another flat rate of $25.60 for the King County WTD charge.
Multifamily households pay a flat rate of $7.00 for the Tukwila charge and $25.60 for the King
County WTD charge. Commercial and industrial customers pay $12.00 for every ERU for the
Tukwila charge and $25.60 for every ERU for the King County WTD charge. Recommended
rates based the recommendations of this plan are presented in Section 9.

3.4 Tukwila Comprehensive Land Use Plan
The City of Tukwila's Comprehensive Land Use Plan (Comprehensive Plan). was, originally
adopted in 1995 and has been amended ,several times since then, including- a 2004 Supplement.
The Comprehensive Plan is a broad statement of community goals and policies that direct the
orderly and coordinated physical development of the City into the future. The Comprehensive
Plan was developed . pursuant to the •_ State Growth -Management Act . (GMA)..Tukwila's
Comprehensive Plan includes the following six GMA required elements: Land Use, Housing,
Transportation, Utilities, Capital . Facilities; and Shoreline. It also. includes the following five
optional elements: Community.. Image, , Economic Development, Natural Environment,
Annexation, and Roles and Responsibilities.
The most pertinent information in the Comprehensive Plan in regards to the Sanitary Sewer. Plan
(SSP) is summarized below.
• Economic Development: This element includes employment targets and states that Tukwila
must plan to accommodate 16,000 additional jobs between 2004 and 2022. It should be .
noted these numbers can not be directly compared to the demographic projections presented
in Section 4 of this SSP since the geographic areas are not identical. The geographic area for
the Comprehensive Plan is all land within the city boundary. The geographic area for the
SSP is the sewer service area, which is less than that within the city boundary.
• Housing: This element includes housing targets and states that Tukwila must plan to
accommodate 3,200 additional housing units (single family and multifamily combined)
between 2004 and 2022. Again, it should be noted these numbers can not be directly
compared to the demographic projections presented in Section 4 of the SSP for the reasons
stated above.
• Land Use: This element provides a map showing land use within the City based on City
zoning. The map is provided in Section 3.5 below along with the zoning definitions.
• Annexation: This element identifies two Potential Annexation Areas . and discusses
associated policies.
• Utilities: This element addresses the goal of providing "utility services and facilities that
meet the community's current and future needs in a safe, reliable, efficient, economic and
environmentally responsible manner." The utilities chapter from the 1995 Comprehensive
Land Use Plan, as well as the 2004 supplement to that chapter, are provided in Appendix E.
The utilities chapter focuses on the following five key issues:
• Service Extensions: Planned extensions of utility services must be based on level -of-
service standards.
Z I Related Plans, Policies and Agreements 3-2
City of Tukwila
• •
DRAFT
• Coordination of Service Providers: The City - managed utilities must be coordinated
with adjacent purveyors who serve portions of the City.
• Concurrency and Implications for Growth: Concurrency requires that utility plans,
along with other capital facilities, be developed so that improvements, or the funds
required for the improvements, are in place at the time they are needed.
• Environmental Sensitivity: Utility improvements . often arise from environmental
concerns, but may also result in additional environmental impacts, such as pipeline
location and construction and from drainage and groundwater management.
• Residential Revitalization: City planned utility improvements and extensions must
place priority on improving and sustaining residential neighborhood quality and
livability.
3.5 Tukwila Zoning Ordinances
Zoning for land within the City of Tukwila is defined in Title 18 Zoning of the Tukwila
Municipal Code. The zoning for the City's current and future service area is shown in Exhibit 3-
1. Anticipated zoning has been established for the Potential Annexation Area south of the
current city limits, even though land use decisions are currently the responsibility of King
County. No major zoning changes are intended in the next 20 years. The 16 zoning
classifications are defined in Table 3 -2.
3.6 King County Sewer Ordinances
King County ordinances related to sewer service are contained in Title 13 Water and Sewer
Systems of the King County Code. These ordinances cover subjects such as levels of service,
criteria for when a sewer plan is required, and King County approval of sewer plans.
Appendix F contains all sewer- related Title 13 ordinances.
3.7 King County Comprehensive Plan
King County's most recent Comprehensive Plan is a draft version of its 2004 plan, which
updates the previous plan created in 2000. The plan guides growth and development in the
unincorporated areas in King County and sets county policy on major issues such as annexations,
transportation, and environmental protection.. The plan includes the following nine elements:
Regional Planning; Urban Communities; Rural Legacy and Natural Resource Lands;
Environment; Parks, Open Space and Cultural Resources; Transportation; Services, Facilities
and Utilities; Community Planning Areas; and Implementation.
The most pertinent information in King County's Comprehensive Plan in regards to Tukwila's
SSP is contained in two chapters. Chapter 2 Urban Communities contains land use information.
Chapter 7 Services, Facilities, and Utilities has a section called Public Sewers and On -Site
Wastewater . Treatment and Disposal Systems which references King County's Countywide
Planning Policies F -239 to F -246; this section can be found in Appendix E.

4.1 Customer Categories and Characteristics
The City divides its sewer . customers into four categories: single family, multifamily,
commercial/industrial, and low income senior /disabled. These categories are defined below.
• Single Family Connections serving one dwelling unit....
• Multifamily - Connections serving more than one dwelling unit.
• Commercial/Industrial — Connections serving non - residential facilities.
• Low Income Senior/Disabled — Connections serving persons with disposable income less
than $32,000 and either at least 62 years old or permanently, disabled. These customers
qualify for a 50% discount.
The number of connections per customer category is shown in Table 4 -1.

4.2 Demographic Projections
Demographic projections were made based on information obtained from the Puget Sound
Regional Council (PSRC). The PSRC makes projections for households and employment based
on official projections from Washington State's Office of Management and Budget. These
projections are available for 10 year increments from 2000 to 2030. The PSRC allocates the
projections across small geographic areas called Transportation Analysis Zones (TAZ).
The process to convert the PSRC data to data specific to the City is as follows.
Planning Criteria
CIty of Tukwila
4-1
•
DRAFT
The geographic boundaries of the TAZs and the City's sewer service area are overlayed to
determine which TAZs, or portions thereof, are in the City's service area For any. TAZ fully in
the City's`service area,'all the households and employment in that TAZ are assigned to the'City.
For any TAZ not fully in the City's service area; the households and employees in that TAZ are
assigned to the City based on,the percent of the TAZ in the City's service area: and. reviews. of
aerial photos and zoning maps. This analysis is done for each year during the planning period,
taking into account how service area boundaries grow over the planning period. It should be
noted this demographic analysis does not reflect development planned under the proposed
Tukwila South Project discussed in Section 2.3. Projected wastewater flows associated with that
project are taken from the project and are not dependent on this demographic analysis.; . .
The results of this analysis are shown in Table 4 -2. Single family households in the City's sewer
service area are projected to increase from 1,499 to 1,822 between 2005 and 2024, a growth of
22 %. It should be noted that the number of single family households actually decreases between
2020 and 2024. The demographic data obtained from PSRC ' shows this decrease, which
presumably is due, to conversion from single family to multifamily households. Multifamily
households are projected to increase from 2,542 to 5,071 .between 2005 and 2024, a growth of
99 %. Employment is projected to increase from 41,060 to 59,207 between 2005 and 2024, a
growth of 44 %. These increases are due partly to' overall growth in the current service area, and
partly due to addition of new lands to the City's service a rea; as discussed in Section 2.2 :-

The exhibit breaks down the flows by service area section. This allows the City to examine how
flows are expected to increase in its current sewer service area compared to how flows are
expected to increase in and because of the new areas. This distinction is helpful since, as
discussed in Section 2.2, the certainty and timing of service area expansion is not fully known.

Exhibit 4-1. Projected Wastewater Flow Generation (gpd)
Since wastewater flows are not metered, projected wastewater generation was calculated based
on the percent of the projected water demand expected to reach the sewer system. This involved
four main steps.
The first step was to generate a water demand forecast for the sewer service area. The water
demand forecast in the 2005 Water System Plan could not be used since the service areas for
water and sewer are not the same.

Excludes employees of the 4 high demand customers.
'High demand customers are customers with very large demand, but relatively few employees. Since they would artificially inflate the overall demand per employee and the resulting demand forecast their water and
employees are treated separately from the regular commercial customers. There are four high demand customers: Shasta, Embassy Suites, Double Tree, and Jorgensen Forge. -
6 This block of water is reserved in the event that a new unexpected large commercial customer moves into the service area.

The second step was to estimate the fraction of water use that reached the sewer system. This
was done by analyzing City' water sales to determine how much water is used year -round for
"base use" compared to `how much water is used during the peak season for "peak excess use."
Peak excess use is the extra, water used during the summer months, most of which is used for
irrigation. It was assumed that all base use reaches the sewer system, while all peak excess use
does not. Table 4 -4 and:Exhibit 4 -2 provide a summary of the analysis. Units for':both are in
ccf, one ccf equals 100 cubic feet.

The third step to projecting future wastewater flow generation was to add a component for the
proposed Tukwila South Project discussed in Section 2.3. These numbers came from the project
Environmental Impact Statement (EIS) and were extrapolated to allocate them over the SSP,
planning period.. This Tukwila South Project wastewater block may duplicate some of the
volumes in the. single family, multifamily, and commercial categories. However,, this is not a
concern since the nuinbers in those categories are relatively small and do not include the growth
expected from the Tukwila South Project.
The fourth step was to calculate the total average day wastewater flow generation by adding the
single family, multifamily, commercial, and Tukwila South Project flows.
To illustrate how the analysis is applied for projecting wastewater flow generation, during the
non -peak season base water use for a single family residence from. able 4-4 is 45,821 ccf.
Based on the City's monthly sales distribution, November to May was chosen as . the non-peak
season and June to October as the peak season. Thus, if 45,821 ccf is divided by 7 (the number
of non -peak months) a monthly average,base water use of 6,546 ccf is obtained. This value is
multiplied by 12 to obtain the annual amount of water considered base use, which is 78,551 ccf.
Since the annual total water use for the single family use category, including "peak excess" use,
is 90,116 ccf (Table 4 -4), the base use of 78,551 ccf is 87 percent of the total single - family water
demand: Thus, based on this analysis, it is estimated that 87 percent of single - family water
demand is expected to reach the sewer system. This 'percentage is 94 percent for multifamily
uses and 77 percent for commercial uses. These estimates of the amount of water that actually
reaches the sewer system are incorporated into the development of Table 4 -3.. •
Since the projected wastewater flow generation is based on the projected water demand, an
overview of how the projected water demand was generated ' is provided below. A more
comprehensive description can be found in the 2005 Water System Plan. The process for
projecting water demand involved the following six steps.
Step 1 Demographic Projections: Demographic projections were generated according to the
process described in Section 4.2.
Step 2 Water Use Factors: Water use factors were calculated by dividing the water sales for a
customer class by the number of respective households or employees. This results in the number
of gallons per day used per household or. employee. ; This water use factor was decreased by
0.5% each year for the first ten years in order to reflect anticipated conservation savings.
Step 3 SF, MF, "Commercial- Regular" Demand: The demographic projections (from Step 1)
were multiplied by the water use factors (from Step 2) to get the demand for the single family,
multifamily, and commercial- regular billing categories.
Step 4 "Commercial -High Demand" Customers: The demand for the commercial-high
demand customers was calculated separately since these large customers with few employees
would otherwise artificially inflate the gallons per day per employee and the resulting demand
for the commercial category. The City does not expect significant changes from the customers in
this category: Therefore, their combined average demand from the last five years was used.

DRAFT
Step 5 Commercial- Future Demand: A block of water for future large commercial customers
was added in case a large customer has an unexpected increase in demand or a new large
customer is added.
Step 6 Total Average Day Demand: The total average day demand was calculated by adding
the results from Steps 3 -5.
4.4 Peak Wastewater Flows
Peak wastewater flows for planning purposes are calculated as the annual average day flow times
a peaking factor plus a component for infiltration and inflow (I/I). Table 4 -3 and Exhibit 4 -1
present the projected annual average day flows for the City from 2005 through 2024. Exhibit 4 -1
further breaks out the flows for the existing and potential sewer service areas.
Peaking factors, e.g., those for maximum daily or peak hourly flows, are selected to represent the
ratio of the peak flow to the average flow that results from the contributions of connected
customers. These selections need to take into account basin -by -basin and other site- specific
factors to arrive at a cost - effective sewer plan or design. In addition, in this SSP, an 111
contribution of 1,100 gallons per day per acre (gpd/ac) is added to arrive at peak wastewater
flows for planning purposes in the Central Business District, an area identified as critical for
further hydraulic analysis. This I/I flow rate, which represents the minimum 20 -year peak hourly
I/1 flow rate estimated by King County WTD, was identified as being appropriate in the Central
Business District for the following reasons:
• This area was developed recently, relative to other areas of Tukwila.
• The oldest piping in this area is approximately 40 years old.
• This area's land cover is primarily pavement, which provides little opportunity for
infiltration.
• This area is served by a robust stormwater drainage system.
• Tukwila confirmed the appropriateness of this assumption based on I/I experience in this
location.
Further, this area has not been identified by King County as a candidate for further evaluation
because of excessive 1/I flow rates.
Section 6 of this SSP presents an analysis of the area of the City identified as the Central
Business District. More detailed computation of the peak flows used in this analysis is presented
in that section.

Section 5
Sanitary Sewer System Design Criteria
The City of Tukwila's sanitary sewer, system design criteria:are established to_guide,both..the,
City and developers in planning and constructing new sewer facilities. This section reviews and
summarizes these.criteria.
5.1 General Basis for Design
5.1.1- Reference Documents
y City design construction of its sanitary sewer
Technical . criteria utilized b the, for the deli .and. construct
infrastructure must be in conformance with the standards of the Department of .Ecology,
(Ecology) manual, "Criteria for Sewage Works Design," dated December 1998, as well as
standards in the City's document, "Development Guidelines and. Design and Construction
Standards." King County Department Wastewater Treatment Division requirements and those of
the;City's Municipal Code must also be met.
Tukwila's Comprehensive Sanitary, Sewer Plan Update' (SSP). ensures orderly and cost- effective
development of existing and future sewerage facilities. All improvements and extensions within:
the service area must be consistent with this plan.
5.1.2 ,.=Reference Datum, .
The reference datum for :the City's sanitary sewer infrastructure is based on the King County
Aerial Survey (KCAS) which is equal -to` the NGVD 1929' datum: King County WTD sewers are
based on, a unique reference datum that equals the 'KCAS'datum: plus one hundred 000') feet.
The King County WTD datum eliminates negative elevations within the King County WTD
service area.
5.1.3' ' Sewer Location
Wherever possible, trunk and interceptor sewers are located in public rights of way. Under some
topographic conditions, sewers may be located in easements across private property.: Where a
sewer line conflicts with other utilities, it must be designed to pass under the other utilities and
have a minimum vertical separation of 3 feet. If the elevation of the sewer prevents it. from,
passing under the other utilities, special construction techniques must be used per the City's
direction.
5.1.4 Separation of Water and Sewer Pipelines
Sewer mains must be laid at least 10 feet horizontally, measured edge to edge, from any. existing
or proposed water supply line. A reduction to 5 feet of separation may be allowed provided the
water main is laid in a separate trench or on an undisturbed earth shelf located on one side of the
sewer at such an elevation that the bottom of the water main is at least 18 inches above the top of
• the sewer.

• •
DRAFT
All sanitary sewer crossings under water mains must be installed such that the top of the sewer
pipe is at least 18 inches below the'bottom of the water�main. An 18 -foot section of sewer pipe
must be located at the crossing so the joints will be is far from` the water supply main as possible.
This installation may require "special structural' support' for. both the water and sewer pipes.
5.1.5 Separation of Wells and Sewer Pipelines
No sanitary sewers can be constructed within 100 feet of a well
5.1.6 Sanitary Sewer Connections
Industrial Connections
Special considerations must be given to sanitary sewer design and connections for industrial
users. The potential for pretreatment requirements, excessive 'wastewater flows, 'special flow
metering, or' sariiplirig requirements prior t� industrial sewer- collection *Or treatment system
design must be considered.
Developer -Connections
Side `sewer connections forking County'WTD interceptor sewer.imes are allowed only by written
permission from King County. The City is the agency through which permits are obtained for
such connections. The permittee is responsible. for. all coordination'.with• King County WTD . for
necessary. inspections ,and approvals.„
5.1.7 General Sizing Criteria
Sanitary side sewers must be sized to carry all sanitary wastewater and waste fluids of any kind
from the buildings served. All toilets, sinks, stationary, wash stands, :floor drains, or any other
piece of . equipment having waste fluids ' must, be connected to the sanitary sewer system.
Commercial minimum sewer diameter is 6- inches.
New sewer systems; except one -lot, single family residences, are designed based on per capita
flows or other methods approved by the City and Ecology. The City requires detailed design
calculations and service area maps for the system design, stamped, signed,, and dated by a
Washington State registered professional engineer.

1.5 Historical Background
The City of Tukwila was incorporated in 1908 and at that time had an area of 418 acres. By
1959, through a series of major annexations, the City's area had increased to 1,739 acres. By
1988 the area had grown to 2,880 acres, again through annexations.
In 1989, another wave of annexations increased the City's area to 5,176 acres. These
annexations included the neighborhoods known as Riverton, Foster, Thomdyke, and Cascade
View, as well as the area served by Fire District No. 1. At the time of the annexations, sewer
service was provided in these areas by several entities — the City of Seattle, Val -Vue Sewer
District, Rainier Vista Sewer District, King County WTD, and the City of Tukwila itself. The

location of the Riverton, Foster, Thorndyke, and Cascade View neighborhood areas, and others
within the current City boundaries, are shown in Exhibit 1 -1.
The annexations brought with them significant population growth. From a population of 800 in
1950, the City grew_ to a population of 3,160 in 1978 and to 10,793 in 1989. By 1991, this figure
had increased to 14,631. The population when the 1999 Addendum was prepared was
approximately 15,000.
In 1995 and 1996, respectively, the City of Seattle transferred sewer facilities in the East
Marginal Way corridor and Ryan Hill service areas to the City. In 1997, the City of Tukwila
constructed sewers in the previously unsewered areas of Allentown. The Boeing Field area (part
of the Manufacturing Industrial Center, Exhibit 1 -1) was also incorporated into the City's
system. Sewer service extension to Foster Point and some of the Foster neighborhood is
anticipated for 2006. Some of the annexed areas that were previously served by other sewer
service providers continued to be served through the original providers.
Except for increases due to the annexations, Tukwila's growth has closely paralleled that of the
adjacent communities of Kent, Renton, and Auburn. The construction of Southcenter Shopping
Center and several industrial parks has also affected population increases.
1.6 Overview of Existing Sewer System
In the past the City has agreements with several external jurisdictions to provide sanitary
sewer service to areas within the City limits. Currently, only the City of Renton and Val-Vue
Sewer District continue to provide such service.
Some of the sanitary sewer service areas within the corporate limits are unsewered or partially
sewered. These areas are served by septic tanks and are often referred to as Septic Areas. Most
of these areas were the result of annexations described above. They were identified in the City's
1994 Unsewered Area Ordinance. Two additional areas that were partially sewered at the time,
the South City and the Riverview neighborhoods, were not identified as such in the 1994
ordinance. Sewer service has been extended to many of the unsewered or partially sewered areas
since the mid 1990's.
Exhibit 1 -2 shows the Sewer Districts within the City of Tukwila.

Section 2
Description of Sanitary Sewer System
This chapter provides basic information about the physical components of the sanitary sewer
system as well as a brief discussion on selected administrative and planning issues related to
operations and future expansion. It provides the basis upon which this Comprehensive Sanitary
Sewer Plan Update (SSP) has been prepared.
2.1 Ownership and Management
The Tukwila sanitary sewer system is owned and operated by the City of Tukwila. The City
operates under a mayoral system of government whereby the City Council establishes policies
that govern the operation of the sanitary sewer system through ordinances and resolutions.
The sanitary sewer system is operated and maintained by the Department of Public Works which
is managed by the Public Works Director. Several divisions exist within the organization overall
to address various facilities and services. There are two divisions associated with the sanitary
sewer system and its operation. These divisions are managed by the Maintenance Operations
Manager and by the City Engineer, both of whom report directly to the Public Works Director.
The Sewer Superintendent, who reports to the Maintenance Operations Manager, is responsible
for the maintenance and operations of the sanitary sewer system, while the Utility Systems
Engineer, who reports to the City Engineer, is responsible for implementing capital
improvements.
Contact information for the Public Works Director is presented below:
Public Works Director: Jim Morrow
Address: 6300 Southcenter Boulevard
Tukwila, WA 98188
Phone: (206) 443 -0179
2.2 Service Area Description
The City of Tukwila is bounded by the City of SeaTac on the west, the City of Seattle on the
north, the City of Renton on the east, and the City of Kent on the south. Exhibit 2 -1 shows the
location of these jurisdictions, as well as the community of Des Moines, Tukwila's city
boundary, and current and potential sewer service areas. The adjacent sewer purveyors, Val -Vue
and Skyway, are also shown on the exhibit.
•
As illustrated on the exhibit, currently the City provides sewer service for much of the area
within the city boundary. Sewer service for the remaining sewered . area within the city boundary
is provided by Val -Vue Sewer District and the City of Renton.
There are no public drinking water supply sources located in Tukwila's service area.

pipelines may need to locate in densely populated areas as the only practical alternative to meet the
demand for service.
F -316 New hazardous liquid and gas transmission pipelines should be located away from
high - density residential zones, Urban Activity and Business Centers, Office Parks,
sports fields, schools and day care centers or other land uses where large numbers
of people would assemble.
F -317 When new, expanded or upgraded hazardous liquid or gas transmission pipelines
are required, use of existing corridors should be evaluated first. King County should
facilitate appropriate corridor sharing among different utility types and owners.
F -318 Hazardous liquid and gas transmission pipelines should not be located in areas
susceptible to soil disturbance or liquifaction or in aquifer recharge areas. When it
is impractical to avoid such areas, special engineering precautions should be taken
to protect public health, safety and welfare.
It is essential to map the location of existing hazardous liquid and gas transmission pipelines within King
County so that developers know where they are and whom to call for information before construction
begins. Accurate maps will assist King County in reviewing land use applications for land uses located
near pipelines.
F -319 King County should map the location of existing and new hazardous liquid and gas
transmission pipelines. Maps shall not substitute the one -call locating system and
shall not be used for any construction or maintenance activity.
Risks to life and property can be minimized by keeping land uses a safe distance from hazardous liquid
and gas transmission pipelines. Pipelines transport a variety of materials, some of which flow under the
force of gravity. While standard setbacks do not assure protection from materials that have the ability to
migrate, setbacks may protect life and property from hazardous materials that are highly flammable,
explosive or toxic. Limiting the allowable uses within pipeline rights -of -way can further reduce risks to life
and property.
F -320 Structures designed for human occupancy shall not be located within hazardous
liquid or gas transmission pipeline rights -of -way and should be set back from the
pipeline to protect public health, safety and property. No structures shall be located
over the pipeline.
F -321 Land uses shall be restricted within hazardous liquid and gas transmission pipeline
rights -of -way. Passive recreational uses, such as hiking trails, may be allowed if the
risk to life and property is assessed and determined to be minimal.
Pipeline failure can result from damage caused by excavation near existing pipelines. Many existing
pipelines initially were constructed in less- populated areas with little development. As demand for land
grows, the risk of conflict between existing pipelines and land development increases.
F -322 King County should promote the safety and reliability of the hazardous liquid and
natural gas transmission pipeline systems by requiring developers, contractors, and
excavators to notify the state, pipeline operators and utilities through the one -
number locator service, before beginning excavation or construction.
F -323 In the interest of safety and reliability of the hazardous liquid and natural gas
interstate transmission pipeline systems, the county should take steps to protect
and preserve the signs that mark pipelines.
GMUAC Recommendation (7- 20-04)
6. Natural Gas Distribution Systems
Natural gas pipelines fall into two major categories: gas transmission lines that transport natural gas from
production fields to local distribution companies and distribution systems that deliver natural gas from
transmission pipelines to retail customers. The federal govemment may define certain parts of the natural
gas distribution system that serve large volume gas users as part of the transmission system. Distribution
systems for transporting natural gas are fundamentally different from transmission gas pipelines and should
be regulated based on their design, use and location.
Gas distribution systems are owned and operated by local distribution utilities. Such systems consist of
the pipelines thatdeliver natural gas to end users together with intermediate supply lines. The distribution
system is constructed incrementally, with addition of new segments and upgrading of existing lines in
numerous small projects. The distribution system is a network that is primarily located in road rights-of-
way, where service is available. Local distribution companies are subject to the comprehensive safety
regulations administered by the Washington Utilities and Transportation Commission (WUTC) under state
law and regulations and by the federal Office of Pipeline Safety under federal law and regulations. The
rates and services of investor -owned utilities also are subject to comprehensive regulation by the WUTC
under state law and regulations. +... -
F -324' King County recognizes that the gas distribution system is primarily located in 'road
rights -of -way.
F -325 King County should promote the safety and reliability of the natural gas distribution
pipeline systems by requiring developers, contractors, and excavators to notify the
state, pipeline operators and utilities through the one- number locator service, before
beginning excavation or construction.
F -326 In th"e interest of safety and reliability of the natural gas distribution pipeline
systems, the county should take steps to protect and preserve the signs that mark
pipelines.
F -327 Structures designed for human occupancy shall not be located within gas . ;=
distribution pipeline rights- of-way and should be set back from the pipeline to
protect public health,; safety and property. No structures shall be located over the
pipeline.
F -328 Permit requirements shall require excavators to ensure adequate protection of any
facilities that are encountered during their work. This shall include but not be limited
to adhering to the foreign facility owners requirements for separation and backfill,
developing Joint plans when drilling or boring parallel to foreign facilities, and
potholing all facilities that will be crossed by drilling or boring.
B. Telecommunications
1. Telecommunications
Telecommunication technologies are changing rapidly and will continue to change during the horizon of this
plan. The future telecommunication system may make little distinction between cable; telephone and
cellular. Telecommunication services include voice, data, video and other communication services on
various mediums including, but not limited to, wire, fiber optic or radio wave. Effective telecommunications
services are critical to citizens in several ways. They promote and enhance individual information
exchange, contribute to a robust regional economy, and afford numerous public services, including delivery
of emergency services, education and opportunities for citizen involvement. •
F -329 King County complies with the Telecommunications Act of 1996 and provides the
widespread availability of telecommunication systems to facilitate communication
•
• GMUAC Relmendation (7- 20-04)
between and among members of the public, public institutions and business in both
the urban and rural areas.
F -330 Telecommunication services are to be encouraged as a means to mitigate the
transportation impact of development and growth.
F -331 Long -term planning for" telecommunications construction; reconstruction and facility
upgrades should include provisions to insure that the system's capacity, design and
equipment will allow users to take advantage of innovative uses, services and
technology.
F -332 Telecommunication
companies and the county should coordinate activities When
facilities are being installed Or road construction projects are scheduled.
-F -333 Long -term planning for telecommunications systems should allow uninterrupted
service, during natural disasters. _.
F -334 Colocation of telecommunication facilities Is encouraged to reduce the unnecessary
proliferation of individual, single -user towers. Colocation shall be required unless
an applicant can demonstrate to the satisfaction_ of the county,that colocation on an
existing tower is not feasible and not consistent with service, quality and access.
F -335 Although visual impacts are always an important consideration in the decision to
approve or deny a proposal, King County shall give greater weight to the visual
impacts of telecommunication facilities proposed to be located on residentially -
zoned lands or in the Rural Area. In addition, the visual impacts of proposals for an
individual tower with a single user shall be given greater weight than proposals to
colocate facilities.
F -336 King County considers the placement of telecommunication facilities within street
rights-of-way as the preferred alternative to the construction of facilities on private
property. Regulatory standards shall require placement in street rights-of-way,
especially within residential neighborhoods and Rural areas, unless such a location
is not feasible or not consistent with service quality and access.
2. Cable Services
King County Ordinance No. 10159 dictates current policy for cable services. It states in part:
" it is the County's policy to promote the widespread availability of cable service and diverse
information to County residents and to encourage the development of cable systems and cable
technology as a means of communication between and among members of the public and public
institutions."
The county's cable- related needs are expressed in the following policies:
F -337 Long -term planning for cable systems should include service to all areas of the
county which meet the minimum density established in the cable company's
franchise agreement and the county's Cable Television Ordinance.
F -338 Cable companies should provide services that meet the cable - related needs and
interests of all segments of the community, taking into account the cost of meeting
such needs and interests.
F -339 Cable companies should take affirmative steps to ensure that reasonable services
are available regardless of income or the income of other people in the person's
neighborhood.
7 -21
GMUAC Recommendation (7- 20-04)
F -340 The goal of Tong -term cable planning should be a high - capacity, state -of- the -art
system. Two-way capacity should be installed and activated. Cable systems should
be interconnected to other communications systems. They should be designed to
be "open"; that is, the systems should be usable by,many, for a variety of purposes.
F -341 Public uses of the cable system should be expanded as the system is upgraded.
3. Internet Access
Rapidly changing technologies are providing opportunities for alternative work environments and lifestyles
as more people transmit and receive information through the Internet. While there is a growing interest in
the use of computer technologies, few new developments are including high -speed intern* access lines or
home cabling. King County encourages private partnering between developers,' builders and
communication providers to expand the opportunities for access to the intemet.
F -342 Developers should collaborate with major employers:to'create developments that
facilitate and encourage teiecommuting by installing high -speed Internet lines during
construction' of the project:
F -343 Builders`and architects should work with the telecommunication industry to design
state -of -the art cable -ready homes and offices:

(King County 9 -2004)
13-15
13.28.035 • WATE• R AND SEWER SYSTEMS
1. A principal requirement and objective of the Vashon Coordinated Water System Plan is the
establishment of service areas to assist the water utilities in providing ;an effective process for the planning
and development of a water system. The Vashon Coordinated Water System Plan defines a service area
as a geographical area assigned to a water purveyor for the purpose of providing both current and future
public water service consistent with local land use plans. The geographic boundaries are defined by
agreements among adjacent utilities and are recorded on a set of maps on file with the department of
development and environmental services, the Seattle/King County department_ of public health, 'and the
department of executive services. Water service provided within a designated service area „is to be
consistent with county land use plans and policies and existing county review procedures regarding water
utility comprehensive plans, a water utility's service area and a planning area. An existing service `area is a
geographic area within which service to customers is available as specifically defined on a map in a utility's
comprehensive plan which is approved by King County as consistent with its land use policies.
A planning area is the remaining geographic area identified on the service area maps contained in
the Vashon Coordinated Water System Plan which is a logical area for expansion of the system. Extension
of service into the planning area requires King County approval as part of the utility's comprehensive plan to
make certain thafthe proposed utility service is consistent with land use plans and policies.
2: Vashon Island purveyors recognize the county's land use policies and will not use water service
as a vehicle to supersede the land use policies and zoning on Vashon Island. The purveyors may perform
satellite management of all class 2, 3 and 4 water systems within their service areas as provided for by the
Vashon: Coordinated Water System Plan.
" 3. An application has been submitted to the United States Environmental Protection Agency
declare Vashon/Maury Island 'water supply as a sole source aquifer. For this reason, a water conservation
program is an integral element of the Vashon Coordinated Water System Plan. All purveyors shall develop
a conservation element as part of their individual water comprehensive plans. The conservation programs
to reduce water consumption as outlined in the Vashon Coordinated Water System Plan shall be in 'place
and operating by"1996 and will be reviewed by the Washington state Department of Health with assistance
from the Water Utility Coordinating Committee. King County will monitor and review the effectiveness of
purveyor conservation plans in conjunction with the approval of their water comprehensive plans. 1991 will
be the base year 'used to establish the average annual per capita water consumption figure for
measurement purposes, adjusted for any weather abnormalities or previous reduction as a result of an
existing conservation program. ` All water utilities shall achieve a four percent minimum total reduction in
water use from _ the 1991 average annual per capita consumption figure by 1996:
A minimum' total reduction in average per capita water consumption of six percent from the 1991
base figure is the stated goal for the entire Vashon/Maury Island Critical Water Supply Service Area by the
year 2000.
B. The Vashon Coordinated Water System Plan identified an unresolved service area dispute
between Westside Water Association and Island Spring Water Company. King County recommends to the
Washington state Department of Health that the area in question be assigned as part of the designated
water service area of Westside Water Association.
C. IGng County approvals of water service areas through water comprehensive plans or developer
extensions will be based upon consistency with V -59 and V-60 of the Vashon Community Plan and F -111,
F -305, F -309, and F -310 of the King County Comprehensive Plan, in effect on March 14, 1991.
D. K.C.C. 17.08.020E exempting new or replacement water mains from fire flow requirements as
long as the main will serve exempt uses only shall be utilized in sizing water mains. Consistent with K.C.C.
17.08.030 A.4 and A.5, if fire protection measures are warranted for buildings over two thousand five
hundred square feet, sprinkler systems, on -site water storage facilities or other measures shall be proven
infeasible before requiring fire flow to the site. (Ord. 14498 § 20, 2002: Ord. 9839 §§ 1-4, 1991).
