requested that the record indicate that he was not present at the 6/17/91
Council meeting, and requested that newspaper articles include such
information in the future.
Councilman Stredicke noted that he voted against the issue because the
recommendations did not require restrictive covenants to ensure that the
campus will be fully integrated with landscaping, pedestrian pathways, and
handicap access. Councilwoman Mathews responded that the Committee had
required that specific plans be submitted to Council for review to ensure that -
conditions are met.
Public Works: Councilman Tanner noted that the Council minutes of 6/17/91, Page 210,
Comprehensive Sewer Item 6, stated that the proposed rate increases for the Comprehensive Sewer
System Plan System Plan are the minimum necessary to implement the City-funded
portion of the improvements. He pointed out that there are at least two other
plans that have been developed by RH2 Engineering that indicate the
improvements can be financed in a number of different ways by changing
the proposed Comprehensive Sewer System Plan parameters.

3) Will residents on Third Street have access?
David Martin stated that it would be possible to put "No Parking" signs on
the left side of Cedar. Mr. Paananen advised that Renton Avenue will be
closed at.the intersection, and that residents on Third have been provided
with an access route.
Council members made the following observations:
1) Road surfaces on Seventh and Cedar need improvement.
2) The stoplight at Seventh and Cedar is very short, and flaggers need to be
aware that there is a problem for other vehicles when large trucks are
allowed to go through that intersection.
3) There is a sight-distance problem at the corner of Fourth and Cedar.
PUBLIC HEARINGS This being the date set and proper notices having been posted and published
Public Works: in accordance with local and State laws, Mayor Clymer opened the public
Comprehensive Sewer hearing to consider the draft Comprehensive Sewer System Plan.
System Plan
Versie Vaupel, P. 0. Box 755, Renton, 98057, stated that she had not been
able to obtain a copy of the Comprehensive Sewer Plan to study, and
requested that Council postpone any decision on this matter until the public
has had an opportunity to review the plan.
Utility Systems Manager Richard Anderson advised that this hearing is for
the purpose of obtaining input from the public which will be taken into
account in preparing the final proposal for the Comprehensive Sewer System
Plan. He noted that following completion of the environmental process, this
matter will be brought before the Council for final adoption. He stated
further that at that time, a formal hearing will be held for further input as
part of the decision-making process.
Mr. Anderson explained that the Comprehensive Sewer System Plan addresses
the management of the City's sewer infrastructure, projected growth,
environmental needs and concerns, and concurrence with long-term land use
planning. Mr. Anderson introduced Consultant Rick Harbert, RH2
Engineering, 8383 158th Avenue NE, Redmond, who reported that the
Comprehensive Sewer Plan is a complete evaluation of the City's sanitary
sewer system, and will be used as a guide in maintaining and improving the
system over the next five years in order to provide City residents with an
effective sewer system.
It was pointed out that the Plan will be a useful tool to:
I) Establish a framework for improvements and operations that govern
sanitary sewer system developments in the City's service area.
2) Provide a guideline for improving the existing system so that each
customer receives adequate sanitary sewer service.
3) Provide a basis for accommodating changes that occur but that cannot be
forecast in the plan.
The scope of the study includes:
1) Analysis of the existing system.
2) Documentation of Council policies regarding growth and annexation.
3) Coordination with adjacent utility systems, and identification of potential
service area boundary adjustments.
4) Estimation of wastewater flow rates using land use designations.
5) Preparation of Capital Improvement Program and estimation of
construction costs.
6) Documentation of existing operations and maintenance programs, and
recommendations for improvements and additions.
7) Analysis of the financial performance of the sewer utility, and
development of a financial operating statement projection.
The Plan addressed key issues,such as excessive infiltration and inflow,
extension of sewer service areas, aquifer protection and exfiltration from
sewers, sewer system deficiencies, and annexation and sewer service outside
City limits.
The following conclusions were reached:
1) Two areas are seriously deficient in capacity:
a) The East Renton area (South Highlands, Maplewood, and Heather
Downs sub-basins); and
•
n• 17 1•61 _ R-n in • I i Min • P._ 21.
b) The Honey Creek sub-basin.
2) Replace most of the system in Downtown Renton, North Renton and the
Highlands area.
3) Perform detailed testing to obtain information regarding the operation of
the system. .
4) Modify design and construction standards for aquifer areas.
5) Set a policy for extension of sewer service:
a) Provide service to unsewered annexed areas.
b) Purchase facilities when an annexed area is provided sewer service
by another municipality.
•
6) The proposed rate increases are the minimum necessary to implement the
City-funded portion of the improvements.
7) The following priorities were considered for facilityimprovements:
a) Structural deterioration and hydraulic capacity problems;
b) Overall efficiency of,an improvement; and
c) Protection of the environment and threat to public health.
Proposed sewer system improvements are as follows:
1) Adopt Comprehensive Sewer System Plan to establish policies and
planning:
2) Replace aging and substandard sewer facilities.
3) Continue development ofthe gravity sewer system to eliminate existing
sewage lift stations.
4) Rehabilitate or replace sewage lift stations that are considered to be
permanent sewage facilities.
5) Examine programs to reduce wastewaterflow rates, infiltration, and
inflow within the sewer system.
6) Implement sewer rate increases to finance capital improvement and
maintenance costs.
Council members made the following inquiries:
1) Why was the area around the 44th interchange indicated on the map
when it is not part of the City's sewer system?
2) Are there water districts that could serve the East Renton Plateau?
I 3) Why do we need to raise utility rates?
Mr. Harbert stated that:
1) The NE 44th area is within the basin boundary.
2) Water District #90 is located in the East Renton area, but is not
approved to provide sewer service.
3) The City's wastewater utility budget earns only enough revenue to meet
the current annual expenses including the repayment of loans to improve
the system. The recommended rates would fund annual planned
expenses.
1 Everett Wilcock, 11830 164th Avenue SE, Renton, requested that copies of
the Comprehensive Sewer Plan be available to the public before the next
public hearing. He suggested that the City review the area's ability to
support sewers and the environmental impact of a sewer extension.
In response to Councilwoman Zimmerman's inquiry, City Attorney Warren
advised that the law would require that one public hearing be held prior to a
final decision on issues, such as the Comprehensive Sewer System Plan.
Councilwoman Keolker-Wheeler noted that the Plan is still on the Utilities
Committee agenda, and that further opportunities for public input'will be
provided.
Versie Vaupel, P. O. Box 755, Renton, 98057, urged that rate increases and
future hearings be widely publicized.
Ray Griffin, 14306 144th Avenue SE, Renton, 98059, stated his opinion that
j the presentation given this evening was not informative.
In response to Councilwoman Zimmerman, Administrator Guttmann stated
that State law requires that the Comprehensive Sewer System Plan be adopted
prior to adoption of the Comprehensive Land Use Plan, and staff has made
every effort to coordinate the two Plans. Ms. Guttmann further stated that
approval will not preclude Council action to adjust or revise the Plan in the
future.
June 17. 1991 Renton City Council Minutes Page 211
• Councilwoman Zimmerman expressed concern that the sewer plan would
drive the City's land use issues. Administrator Guttmann advised that the
sewer system plan is a generalized document regarding hydraulics and the
physical system based on sensitivity to land uses, but those uses would not
govern the Comprehensive Plan. Ms. Zimmerman also urged that the City
focus on sewer concerns within its boundaries, and allow the County to solve
its sewer problems without pressure by the City.
Administrator Guttmann cautioned that the East Renton Plateau drains into
the City's aquifer, and could seriously contaminate the City's water supply.
She reported that staff has presented the proposed Comprehensive Sewer
System Plan information to County officials and County Council members,
and is investigating ways that the County and City can resolve sewer issues
jointly.
In response to Councilman Stredicke's inquiry, Mr. Harbert said that the area
south of Valley Medical Center is served by a line constructed jointly by the
City and the Cascade Sewer District. He further stated that the line falls in
east/west alignment to 192nd, and has been sized in accordance with existing
land use development in the area. Mr. Harbert anticipated that the City will
serve that area to the City limits, and Soos Creek Sewer District (formerly
Cascade Sewer District) will serve the County property beyond.
Everett Wilcock, 11830 164th Avenue SE, Renton, said that County residents
are sensitive to Renton's aquifer needs, and have initiated efforts to educate
citizens on the proper use of septic tanks. He stated further that County
residents are concerned about the liveability of the community and how
funds are used. Mr. Wilcock urged that planning be slow, thorough and for
the good of the whole community.

Transportation in accordance with local and State laws, Mayor Clymer opened the public
Improvement Program, hearing to consider the 1992-1997 Six-Year Transportation Improvement
1992-1997 Program (TIP). Transportation Systems Manager Melvin Wilson gave a brief
overview of the Plan, and noted that the 1992-1997 TIP emphasizes multi-
modal and Transportation Demand Management (TDM) activities.
Mr. Wilson reported that the proposed direction of the Plan reflects input
from several sources, such as the Council Transportation Committee, Citizens'
Advisory Transportation Committee, Planning Commission, and regional
transportation legislation (Clean Air Act, Transportation Demand Management
Law). Mr. Wilson introduced Traffic Specialist Lee Haro who explained that
the adoption of the annual Six-Year TIP is mandated by the State Legislature,
and is submitted to the State Department of Transportation and adjacent
municipalities following annual approval by the Council. The purpose of the
TIP is to involve citizens and elected officials in the process of identifying
the City's priorities for transportation improvement funding; and when those
priorities are identified and the plan has been approved, funding authorities
and adjacent jurisdictions are notified to ensure coordinated planning
throughout the region. In his presentation, Mr. Haro identified 54 projects
which were listed and prioritized for completion during 1992-1997. The first
ten priorities of the TIP are listed as follows:
1) Street Overlay Program
2) Oakesdale SW - SW 31st to SW 16th
3) North Renton Liveable Streets
4) Park Avenue North/Lake Washington Boulevard
5) South 43rd Street (LID 329)
6) Park Avenue North - Bronson Way North to North 10th Street
CHAPTER I
SUMMARY AND INTRODUCTION
A. PURPOSE OF PLAN
The purpose of the Renton Comprehensive Sewer System Plan is to present policy and design
criteria and to recommend facility improvements. This plan will be used as a guide in
maintaining and improving the sanitary sewer system over the next five years in order to provide
the residents of the City with an effective, safe and reliable sewer system. This plan is not an
update to the Comprehensive Sewer Plan adopted in 1983; it is a complete re-evaluation of the
entire sanitary sewer system. A summary of this plan's findings and recommendations are
presented in this chapter.
The plan results from a study that evaluated the existing sanitary.sewer system and developed
recommendations to resolve existing deficiencies and concerns,and to accommodate growth. The
improvements identified in this plan are based on the requirements of the Washington State
Department of Health, Washington State Department of Ecology and City Policy.
The City of Renton adopted its last Comprehensive Sewer Plan in 1983. That plan anticipated
growth in the system and proposed improvements but did not foresee all of the issues that have
arisen- since that time: 1) concerns for groundwater protection, 2) significant increases in
construction cost, and 3) increases in land use densities. These issues and others are examined
in detail in this Comprehensive Sewer System Plan.
The Renton sanitary sewer system is large, and because of the topography, it is difficult to
comprehend. The condition of the current system, as well as the need for improvements, has
been documented in this report. Due to the complexity of this system and the number of issues
that must be addressed, this report is organized so that a reader may review a summary of it in
this chapter without reading the background or detailed information that led to those results.
The plan provides a recognized framework for making decisions about sanitary sewer service in
the City of Renton. It is intended to aid decision makers as well as users, including the
Wastewater Utility, City Council members, the Mayor and staff, builders,developers,community
groups, and other government agencies. The plan will be a useful tool in the following ways:
• As a framework for improvements and operations that govern sanitary sewer
system developments in the City's service area. The plan provides a basis for
allocating improvements and costs to new sanitary sewer system users such as
home and apartment builders, and commercial developers. It thus provides City
officials with partial direction for approving building permits and upgrading the
system.

CHAPTER ONE
• To provide a guideline for improving the existing system so that each customer
receives adequate sanitary sewer service. It is intended that City officials be able
to use these guidelines to maintain a high quality of service at a reasonable cost.
• To provide a basis for accommodating changes that occur but that cannot be
forecast in the plan. To this end, the plan lists policy issues and operational
criteria that can be used to develop alternatives and directions for development,
improvements and operations.
Several members of the City staff_have a detailed understanding of the City's sanitary sewer
system, and have provided valuable input for this plan. Mr. Richard Anderson, Mr. Randall
Parsons, Mr. Mike Benoit, Mr. David Christensen, Mr. Gary Morrison and Mr. Jack Crumley are
thanked for their assistance.
B. AUTHORIZATION
On November 7, 1988, the City of Renton authorized RH2 Engineering, P. S. to prepare the
update to the Comprehensive Sewer System Plan in conformance with the Chapter 173-240
WAC.
C. SCOPE OF STUDY
The scope of study includesthe following:
Analyze the existing system to determine its deficiencies and needed improvements.
Document City Council policies regarding growth and annexation.
Coordinate plan with adjacent utility systems and identify areas for potential service area
boundary adjustments.
Estimate wastewater flow rates using land use designations.
Prepare a Capital Improvement Program and estimate construction costs.
Document,in summary form,the existing operations and maintenance program and make
recommended improvements and additions.
Analyze the recent financial performance of the sewer utility and develop a financial
operating statement projection.

Summary and Introduction
D. EXISTING SEWER SYSTEM
The City of Renton owns, operates, and maintains its sanitary sewer system. This system
consists of approximately 153 miles of gravity sewer, 23 sewage lift stations and force mains,
and approximately 3000 manholes. Wastewater is discharged to METRO facilities at 55 locations
within the City from which it is conveyed to and treated by METRO's Renton Treatment Plant.
The existing sanitary sewer system is shown on FIGURE 1.
The City of Renton is divided into six major wastewater collection basins, each of which consist
of one or more subbasins. For the most part, these collections basins and subbasins follow the
natural drainage patterns of the Renton service area. These wastewater collections basins are
shown on FIGURE 1.
E. POLICIES AND DESIGN CRITERIA
Policies, design criteria, and standards used for planning and operating the sanitary sewer system
are based on laws and policies which originate from several sources. All these policies and
standards have the general purpose of providing an acceptable level of service to the sanitary
sewer customers. Policies presented in this plan include the following: customer service policies,
financial policies, facility policies, and organizational policies. Analysis and design criteria for
the sanitary sewer system are based on standards presented in the "Criteria for Sewage Works
Design" prepared by the Washington State Department of Ecology as well as standards set by
the Municipality of Metropolitan Seattle (METRO) and City of Renton.
F. LAND USE AND ADJACENT SYSTEMS
Land use proposed in the City's 1983 Comprehensive Land Use Plan was used to estimate
wastewater flow rates at saturation conditions within the City. These saturation wastewater flow
rates were used to analyze existing sewerage facilities and to plan for the location and sizing of
new sewerage facilities. Existing land use designations are shown on FIGURE 6.
There are several adjacent utility systems surrounding the City's existing service area,which limit
the expansion of the City's sewer system. The greatest potential for expansion of the City's
sanitary sewer system is within the May Creek and East Renton areas which currently either do
not have existing or adequate sanitary sewer facilities. The adjacent utility entities are shown
on FIGURE 7.
1-3
CHAPTER ONE
G. KEY ISSUES
This plan addresses the following key issues:
• Excessive infiltration and inflow.
• Extension of sanitary sewer service areas.
• Aquifer protection and exfiltration from sanitary sewers.
• Sewer system deficiencies including hydraulic constraints, substandard facilities, and
replacement of old pipes.
• Annexation and sewer service outside City limits.
Several of these issues were also addressed during preparations of the 1983 Comprehensive
Sewer Plan.
H. SYSTEM ANALYSIS
A hydraulic and a structural analysis were conducted to determine how well the existing system
achieved current policies and technical, engineering standards. The plan identifies where the
system failed to meet those objectives and recommends improvements to the existing system or
construction of new facilities to achieve them.
A hydraulic analysis is a computer simulation of the existing system to determine its ability to
convey wastewater saturation flow rates. A computer model was developed and used to analyze
the system and to size future facilities. This computer model will continue to be used by the City
as an analytical, planning and management tool. A structural analysis, which is a visual
inspection of the existing system, was also conducted and was based on video, as well as actual,
physical inspections.
The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies
identified are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to
handle wastewater flow rates, pipes that are less than 8-inches in diameter and sections that have
reverse slopes. Structural deficiencies identified are pipe sag, and root and grease problems. The
Renton sewer system has these hydraulic and structural problems in varying degrees throughout
the system.
I. SEPA
A SEPA Checklist has been prepared for this plan and is presented in Appendix E. It is
anticipated that this proposed plan will not have a probable significant adverse impact on the
environment and that an environmental impact statement (EIS) will not be required. However,
1-4
Summary and Introduction
many of the projects proposed herein will require SEPA checklists and some will require an
environmental impact statement.
J. CONCLUSIONS AND RECOMMENDATIONS
In the development of this plan, the following conclusions were reached:
1. Two areas are seriously deficient in capacity: 1) The East Renton area (which
includes South Highlands, Maplewood, and Heather Downs Subbasins) currently
has a moratorium on connections until capacity improvements have been made,
and 2) the Honey Creek Subbasin is at capacity and has some marginally reliable
facilities.
2. A substantial percentage of the system has reached the end of its useful life and
needs to be replaced. These areas include the Downtown, North Renton and
Highland areas.
3. The City needs to perform detailed testing to obtain better engineering information
regarding the operation and hydraulic behavior of the system. Specifically, a
detailed infiltration and inflow project should be performed as well as a video
inspection to affirm this plan's evaluation and provide an improved basis for
future planning.
4. Design and construction standards need to be modified for use in aquifer
protection areas. We recommend that a zero leakage policy be adopted for sewers
within the Downtown and Maplewood aquifers. A specific example of an
extremely high risk is METRO's Cedar River Interceptor sewer which currently
traverses through the Downtown aquifer. We recommend that this sewer be
relocated so that a failure or leakage is manageable, and contamination of the
City's sole source aquifer is avoided. However, a zero leakage policy requires a
special type of construction which would substantially increase costs over standard
construction costs.
5. We recommend that the City adopt the following policy regarding extension of
sewer service; where the City annexes an area that is currently unsewered by
another municipality, the City should provide sewer service; where annexation
occurs and sewer service is provided by another municipality, the City should
purchase the facilities from the adjacent municipality, based on that municipalities
actual depreciated cost for providing the facilities to obtain service, so long as
those facilities flow by gravity to the City system.
6. The rate increases recommended in this plan should be considered as the
minimum level of increases necessary to implement the City-funded portion of the
recommended improvements. Currently, new development pays a major portion
1-5
CHAPTER ONE
of the remaining cost of recommended improvements. If funding from this
source, such as the special utility connecting fee, is not available, the City's share
of these construction costs will most likely increase.
7. The City's sewer system is complicated; the preceding conclusions and
recommendations are based on the highest priority issues, which, in our opinion,
must be confronted. However, we propose a substantial number of additional
recommended facility improvements and modifications. When we assigned them
priorities, we took into consideration the following characteristics:
a. Whether a facility is structurally deteriorating or has hydraulic
capacity problems.
b. Whether an improvement increases overall efficiency by reducing
operation and maintenance costs.
c. Whether an improvement helps protect the environment or reduces
a threat to public health.
K. SYSTEM IMPROVEMENTS
The following is a summary of proposed improvements to the Renton sanitary sewer system,
which are presented in this Comprehensive Sewer System Plan,, to correct existing facility
deficiencies and to accommodate growth.
1. Adopt this Comprehensive Sewer System Plan in order to establish consistent City
policies and to provide the capability of efficiently planning the sanitary sewer
facility improvements. This plan should be updated at intervals of no greater than
five years in order to accommodate unforeseen changes in existing assumptions
and conditions, and for adjusting budgets and sewer service rates.
2. Replace aging and substandard sanitary sewer facilities within the City. These
sewers present a significant potential danger to the environment and public health.
3. Continue development of the gravity sewer system in order to allow the
elimination of existing sewage lift stations. These lift stations are less reliable,
require higher maintenance and operation costs, and cause more adverse impacts
to downstream facilities than do properly planned gravity sewer systems.
4. Rehabilitate or replace the sewage lift stations that are considered to be
permanent sewage facilities. These improvements will reduce maintenance costs
and increase system reliability.
1-6
Summary and Introduction
5. Examine programs and projects that will reduce wastewater flow rates and
infiltration and inflow within the sanitary sewer system. These may be cost-
effective methodsthat could possibly reduce the size of sanitary sewer facilities,
thereby reducing capital expenditures.
6. Implement sanitary sewer rate increases in order to finance capital improvement
costs as well as operation and maintenance costs in accordance with the utility
rates study.
L. HOW TO USE THIS PLAN
This plan is arranged in eight major sections:
Chapter I provides a summary of the recommendations and conclusions presented in this
Comprehensive Sewer System Plan.
Chapter H provides a general overview of the existing sewer system and a definition of
terms.
Chapter III presents specific policies that guide the operation of the sewer system.
Chapter IV examines the land use policies that guide how the City of Renton
accommodates growth; and presents the land uses,joint use agreements and design criteria
that were used to develop wastewater saturation flow rates on which the computer
hydraulic analysis is based.
Chapter V describes and analyzes of all components in the existing system and presents
their recommended improvements.
Chapter VI further describes the improvements necessary to resolve existing deficiencies
and accommodate growth. The proposed improvements are also listed by priority and by
project type.
Chapter VII examines the operation and maintenance programs for the sanitary sewer
utility.
Chapter VIII presents the costs of the proposed improvements and the anticipated level
of rate increase necessary to support them.
