From: Jeff Tate, Assistant Director of Community Development Services
Date: March 11, 2015
Re: Communal Residences — Refinements to February 23, 2015 Transmittal
On February 23 d staff transmitted a memo and draft code amendments to the Planning
Commission for discussion at the March 3 d Planning Commission meeting. Since that time,
staff has had the opportunity to review one public comment that was submitted, reflect upon
some of the questions that were asked during the March 3 d meeting, and to discuss the draft
amendments internally with Code Enforcement and Planning staff. Attachment A provides an
updated version of the draft code amendments. A general explanation of the attached revisions
is as follows:
1. Modifications are shown in blue.
2. Several minor modifications are proposed that are intended to clarify meaning and
intent.
3. Staff proposes to make the following modifications that simplify the meaning and
implementation of the regulations:
a. Remove the reference to the R16 and R20 zones that further restrict occupancy
based on parking and expand the parking section to make reference to the need to
have one parking space per tenant. The existing code language already requires
one space per tenant irrespective of zoning. This standard will continue to work for
the high density communities located in the R16 and R20 zoning designations since
it also requires that each space be exclusively dedicated.
b. Remove the reference to bedrooms and simply cap the occupancy number at 4. The
rationale for removal of this standard is that the parking space standard will more
effectively further limit occupancy and that it is an obvious external indicator of
maximum occupancy since it is easy to count parking spaces outside and to know if
a garage can occupy one, two or three automobiles. Furthermore, staff is in a better
position to demand that a property owner open a garage and verify if it can be used
for parking vs. demand entry into a home.
c. Remove the amortization schedule in order to eliminate confusion on its meaning as
we move forward with implementation.
4. In the definition of Communal Residence staff proposes to clarify that these properties
are not only a type of dwelling unit but that they are also operating as a business.

MEMORANDUM
WASHINGTON
TO: Judi Roland, Chair, Planning Commission
Ron Copple, Vice - Chair, Planning Commission
Planning Commission Members
FROM: Susan Fenhaus, Water Utility Engineer
Lisa Tobin, Utilities Engineering Manager
DATE: March 9, 2015
RE: 2015 Comprehensive Water Plan — Initial Briefing
The City is in the process of updating the Comprehensive Water Plan (Water Plan).
The final plan will consist of two large binders; one containing data, analyses, and
proposed improvements, and one containing appendices. The City Council recently
completed its initial review of the entire plan at a February 2015 study session.
Since the last water plan was prepared (in 2009, with adoption in 2012), the water utility
has supplemented its own water supply sources with additional supply from the regional
surface water system (Tacoma's Pipeline 5). Of the 26 projects and programs identified
in the 2009 Comprehensive Water Plan, 23 of the projects and programs have been or
will be completed this year.
The Executive Summary of the Water Plan is attached for your review prior to the initial
Planning Commission briefing on March 17, 2015. At the Planning Commission
meeting, Water Utility staff will provide a chapter -by- chapter summary of the key
information contained in the plan, especially the policy chapter (Chapter 3) and the
near -term (6 -year) and long -term (20 -year) capital improvement program (Chapter 10).
An electronic version of the Preliminary Draft Comprehensive Water Plan can be found
on the City's website at
http:ffweblink.auburnwa.ovf xternal/ Iectronicile .aspx ?docid= 256143dbid =0
Executive Summary
COMPREHENSIVE WATER PLAN
ES.1 INTRODUCTION
This executive summary presents a brief overview of the City of Auburn (City)
Comprehensive Water Plan (Plan) including the need for this Plan and proposed
improvements for anticipated future growth. The City initiated this Plan recognizing the
importance of planning, developing, and financing water system facilities to provide reliable
and efficient service for existing customers and to serve anticipated growth. The Plan is
designed to meet state, county, and local requirements. It complies with the requirements of
the Washington State Department of Health (DOH) as set forth in the Washington
Administrative Code 246- 290 -100, Water System Plan.
This Plan contains timeframes that are the intended framework for future funding decisions.
However, these timeframes are estimates and may change depending on factors involved
in the processing, project work, and availability of funding. The framework does not
represent actual commitments by the City.
ES.2 PLANNING CONSIDERATIONS
The City's Retail Water Service Area (RWSA) boundaries were initially defined through both
the South King County and Pierce County coordinated water - system planning process. The
RWSA boundary includes areas within the City limits and potential annexation areas (PAA)
as shown on Figure ES.1.
Several water purveyors adjoin the City of Auburn RWSA, as shown in Figure ES.2. These
include the cities of Algona, Bonney Lake, Kent, Pacific, and Sumner. Also included are the
Covington Water District (CWD), Lakehaven Utility District (LUD), Water District #111
(WD #111), Highline Water District (HWD), and the Muckleshoot Indian Tribe (MIT). Since
the last Plan (adopted in 2012), minor adjustments to the boundary with Bonney Lake in
Pierce County have been agreed upon in principal. Council approvals of the new
boundaries are expected in 2015.
Interties provide a tool that water utilities use to move water between systems to meet
supply needs, to increase reliability and to respond to emergencies. The City maintains
wholesale supply interties with three adjacent water systems: Algona, CWD, and WD #111.
The City also has emergency interties with LUD, WD #111, and the cities of Bonney Lake,
Kent, and Pacific.

ES.3 POLICIES AND CRITERIA
City policies are established in order to support a vision or mission and to provide a
framework for the design, operation, and ongoing well being of the City's water utility. The
policies establish consistency and to ensure that adequate levels of service are provided
throughout the system. The policies also provide documentation to current water - system
customers, as well as those considering service from the City.
The City's Plan establishes the following mission statement for the water utility:
"The City will provide for the efficient, environmentally sound and safe management
of the existing and future water system within Auburn's service area."
The policies included in this plan are developed specifically for the City's multi- source
municipal water system (System Number 03350V). Table ES.1 summarizes key policies
and criteria. The Plan summarizes policies and criteria relating to business practices,
service area, operation and maintenance (O &M), financial, planning, environmental
stewardship, and design and construction.
Table ES.1 Service Area Policies Summary
Comprehensive Water Plan
City of Auburn
Policy Name
Policy Statement
Business Practices
City desires to employ recognized best business practices which result in the
efficient and cost effective operation of the utility. The City shall identify the key
business functions within the utility and develop supporting best business
practices for each. The utility will conduct a performance audit every six years in
conjunction with its capital projects planning cycle to evaluate how well best
business practices are being implemented and how effective they are.
Retail Service Area
The City will plan for and provide water service to all customers with firm
contracts. As supply permits, the City may provide water to customers without
firm contracts.
Conditions of Service
For areas outside the current City limits, but within the RWSA, the City shall
condition service on agreement that development is in compliance with City
development standards.
Service Extension
Extension of the water system should be allowed provided the area to be served
is within the City's RWSA, the proposed development is consistent with adopted
development policies, and associated City costs are reimbursed. Property
owners shall be responsible for extending the water system through the full
extent of their property as required by Auburn City Code.
Source of Supply
It is the City's goal to have sufficient system -wide supply facilities (including both
permanent and emergency interties) to meet the maximum daily demand (MDD)
of the entire system with any single active water supply source out of service.
Pump Stations
The City's goal is to have sufficient capacity to allow full service with any single
pump out -of- service.

Table ES.1 Service Area Policies Summary
Comprehensive Water Plan
City of Auburn
Policy Name
Policy Statement
Reservoir Storage
The City will provide sufficient storage volume so that each storage component
(operational, equalizing, fire fighting and emergency) is provided separately,
recognizing that a fire could occur during an emergency (supply or pump station
out -of- service).
Fire Flow
The City has established a fire flow criterion of 1,500 gallons per minute (gpm)
for all single - family residential areas of the City and 2,500 gpm for all multifamily
residential and all other non - residential land use areas, except parks and open
spaces within the City.
Hydrants
The maximum distance between fire hydrants in single - family use district zones
shall be 600 feet. The maximum distance between fire hydrants in commercial,
industrial, and apartment (including duplex) use district zones shall be 300 feet.
Dead -end Mains
Provisions shall be made wherever appropriate in any project for looping all
dead -end or temporarily dead -end mains.
System Pressure
The City of Auburn has established an acceptable system pressure range of 35
to 80 pounds per square inch (psi) for all new facilities. During fireflow conditions,
a minimum pressure of 20 psi is allowed.
Distribution System
Pipe velocities shall not exceed 8 feet per second in all water mains.
Water Use Efficiency
The City will target a 1 percent reduction in equivalent residential unit value for
Goals
each year until reaching a water use per Equivalent Residential Unit (ERU) of
172 gallons per day (gpd) per ERU.
Non - revenue water
The City will strive to maintain levels of water leakage for its distribution system
(water leakage)
at less than 10 percent.
ESA WATER REQUIREMENTS
The City's water requirements, or demand, was projected for each customer class (single -
family residential /duplex, multifamily residential, commercial, manufacturing / industrial,
schools, city accounts, and irrigation). Demand projections were expressed as Equivalent
Residential Unit (ERU), average day demand (ADD), and maximum day demand (MDD).
One ERU is defined as the average quantity of water beneficially used by one average, full -
time, single - family residence per day. The quantity of water used by other customer
classes, and by the whole system, can be expressed in terms of equivalent ERUs. The
ADD is typically used in operational evaluations. The MDD represents the single largest day
water demand during the year and is a key parameter for infrastructure sizing.
The City provided water to approximately 56,000 people through 13,910 retail accounts as
of the end of 2013. Between 2008 and 2013 the average day demand (ADD) has ranged
from 7.16 million gallons per day (mgd) in 2011 to 8.61 mgd in 2009 and averaged 7.74
mgd. The MDD has ranged from 11.43 mgd in 2011 to 14.36 mgd in 2009. From 2008 to
2013, the total number of connections increased by 6 percent, while the average annual
total water consumed declined by approximately 10 percent. The decline was likely caused
by multiple factors, including the economic downturn from 2008 to 2010, continued water
February 2015 — DRAFT ES -5
pw //Carollo/Documents /ClientMA/ Auburn /9466A00 /Deliverables /Executive Summary doc
use efficiency (WUE) activities, and higher water use efficiency in new and renovated
homes and offices.
The total projected annual ADD and MDD, along with wholesale demands, are summarized
in Table ES.2. Projected demands were developed based on projected customer accounts,
which used demographic growth rates provided by the City, and the expected water use.
The expected water use was based on historical information. The City has historically used
the 75th percentile statistic in its demand projections to provide a factor of safety, without
being overly conservative. For comparison purposes, the average water use can be
expressed in relation to ERUs where water use per ERU was 195 gpd /ERU. The peak
demands can be expressed as an MDD /ADD peaking factor, which is the relative
magnitude of MDD compared to the ADD. The City's MDD /ADD peaking factor was 1.82.
Distribution system leakage (DSL) was also included in the demand projections. DSL
represents the difference between production and documented water use (retail, wholesale,
and authorized unmetered). State rules require that the three -year average of distribution
leakage be maintained at less than 10 percent of the supply. The total 3 -year rolling
average DSL for 2000 through 2013 was between 5.6 percent and 9.7 percent of the total
production, meeting the regulatory requirements. The City has chosen a planning value of
9.5 percent for DSL by using the 75th percentile of the historical data.
The City has wholesale agreements to sell water to the City of Algona, CWD, MIT, and
WD #111. The current contract with Algona is a firm wholesale agreement to deliver
525,000 gallons of ADD and 1,114,000 gallons of MDD. The City also needs to plan for
supply to the MIT future fish hatchery. An agreement dated from 1986 requires that the City
provide the tribe with a firm average annual demand of 2.5 mgd from Coal Creek Springs
and a firm maximum demand during the summer of 1.9 mgd.
The City's agreements with CWD and WD #111 is on an interruptible basis and requires the
City to sell 2.5 mgd to CWD and 2.5 mgd to WD #111. CWD did not renew its purchase
agreement in 2010; however, the City may provide supply per the Interlocal Agreement 2
upon request of CWD as determined by the City.

ES.5 EXISTING SYSTEM
The City owns and operates a multi- source municipal water system (DOH ID 03350V),
which includes supply, treatment, storage, and distribution of potable water to residential,
commercial, and wholesale customers. Service is provided to four major service areas,
February 2015 - DRAFT ES -7
pw //Carollo/Documents /ClientMA/ Auburn /9466A00 /Deliverables /Executive Summary doc
which are further divided into pressure zones as required by local topography. The major
service zones and associated service elevations are summarized in Table ES.3.

The City's four major service areas and the location of key elements of the water system
are shown in Figure ES.3.
The City sources of supply include two springs, ten wells, and Tacoma wholesale water
supply. Wells 1, 2, 3A, 313, 4, 6, 7, Coal Creek Springs, and West Hill Springs provide water
to the Valley service area, while Wells 5, 5A, and 5B provide water to the Lakeland Hills
service area. Tacoma wholesale supplies are received through two interties: the B St NW
Intertie in the Valley Service Area and the 132nd Ave SE Intertie in the Lea Hill Service
Area.
The City operates and maintains pump stations to move water throughout the piping
network and to provide water at the required service pressures. Pump stations supply water
from the Valley Service Area to the Lea Hill, Academy, and Lakeland Hills Service Areas.
Additionally, booster pump stations are used to supply high elevation areas in the
Academy, Lea Hill, and Lakeland Hills Service Areas. The City also operates the Intertie
Pump Station in Lea Hill Service Area to provide wholesale supplies to WD #111.
The City currently maintains a total of 15.8 million gallons (MG) of water storage in eight
water reservoirs. Each of the City's service areas contains two reservoirs to aid in system
operation and maintenance.
Water treatment in the City includes chlorination, corrosion control treatment (CCT), and
metals removal. All wells, except Well 5, are equipped with some level of treatment. Water
quality improvements have recently been completed at several sites to convert the current
gas chlorination systems to hypochlorite. Hypochlorite systems are a safer way to operate
disinfection facilities.

The City's water transmission and distribution system includes nearly 250 miles of pipeline.
Pipe size varies from 4 to 24 inches, with predominance of 8- and 12 -inch diameter pipe.
The existing data shows that over 90 percent of the distribution system is ductile -iron (DI)
pipe. Pipes made of asbestos - cement, steel, and concrete cylinder make up the remaining
pipes in the system. In 2015, the last remaining asbestos - cement pipes in the water system
will be replaced with DI pipe.
ES.6 WATER RESOURCES
The City currently holds certificated, primary water rights and claims with a total
instantaneous flow (Qi) of 19,075 gpm (27.47 mgd) and an average annual flow (Qa) of
21,002 acre -foot per year (ac- ft/year) (18.75 mgd). The City's water rights are sufficient to
supply the City through 2035; therefore, no new water rights applications are
recommended.
The City's total instantaneous supply capacity is 14,686 gpm (21.15 mgd) and the total
annual capacity is 17,104 ac- ft/year (15.02 mgd) mgd, based on the City's ability to pump
from the existing system. The existing instantaneous supply capacity will be deficient
starting in 2019. The City will need to provide a minimum additional supply of 2,100 gpm by
the end of the planning period to address this deficiency. To meet the projected deficit, the
City has developed a five -part water supply strategy as follows:
Improve existing supply facilities: The source improvement strategy to meet the future
demands includes improvements to Coal Creek Springs, manganese treatment of
Well 7, and expansion of Howard Road CCT. Additionally, Well 2 and Well 3A /B will
be replaced to maximize the capacity and operational flexibility of the water system.
Manganese treatment may also be needed for Well 3A /B to make full use of these
supplies.
Use cost - effective wholesale supplies from Tacoma to their full extent: The City has
obtained 3,556 gpm (5.12 mgd) of peak season and 1,736 gpm (3.5 mgd) of average
day wholesale supplies from Tacoma. The City may also secure additional permanent
or temporary (market -rate) supplies from Tacoma in the short -term planning period.
Secure additional water rights: The City has an application into the Ecology for new
primary water rights. The new rights will provide supply for the City, Algona, MIT,
Covington Water District, and WD #111. The City may also consider securing
additional wholesale supplies from Tacoma.
Consider opportunities for water reuse: Water reuse, as reclaimed water, is a
potential source of supply. No reclaimed water is currently available from King County
Metro sewer system in the City, who treats the City's sewage. The City will continue
to participate in local and regional wastewater reuse planning efforts to identify new
opportunities.
February 2015 — DRAFT ES -10
pw //Carollo/Documents /ClientMA/ Auburn /9466A00 /Deliverables /Executive Summary doc
Continue an aggressive Water Use Efficiency Program: To reduce or delay the need
for more supplies the City will continue to reduce demand through a WUE, which is
discussed in more detail in an subsequent section.
ES.7 WATER QUALITY
The City is in compliance with all current regulatory requirements, including monitoring
requirements. The following actions are recommended to maintain future compliance:
It is recommended that the City continue its monitoring program. Continue to routinely
evaluate water quality parameters and potential issues throughout the system to
maximize the water supply benefit and minimize potential adverse water quality
issues.
2. The City should continue to coordinate with Tacoma concerning the water quality of
the wholesale supplies. It is recommended that the City add continuous chlorine
analyzers at each intertie with supervisory control and data acquisition (SCADA)
connections to monitor and record residual at the interties. Additional sampling at the
Tacoma interties is recommended to fill in gaps in existing source water quality data.
3. Continue to take actions recommended by the DOH to correct deficiencies identified
in the 2012 Sanitary Survey.
4. Contact the DOH regional engineer to determine whether treatment provided at the
City's sources is sufficient to provide 4 -log virus inactivation or removal, especially
West Hill Springs and Well 1 (upon completion of the improvements).
5. Update the City's Water Quality Management Plan, as necessary, to address
changes due to forthcoming source improvement projects.
ES.8 WATER USE EFFICIENCY
The development of the WUE program is the foundation for using water wisely. The 2015-
2020 WUE program will be a continuation of the existing program with specific
enhancements to the program to comply with current regulations. The proposed goal for the
2015 -2020 WUE program will target a 1 percent reduction in the ERU value per year from
the current planning ERU value of 195 gpd /ERU. Re- evaluate goal when the planning ERU
value reaches less than 172 gpd /ERU. WUE measures are projected to reduce retail MDD
by 1.72 mgd by 2020 and 3.53 mgd by the year 2035, as shown in the Figure ES.4.
The City is planning to implement water meter and billing system improvements that will
provide advanced meter infrastructure (AMI) throughout the system during the 2015 -2020
program period. In addition to the operational and financial benefits, AMI will provide a new
tool for the WUE Program. For example, the AMI meters may be able to identify
substantially more water loss reduction opportunities than previously possible.

ES.9 SYSTEM ANALYSIS
The City's water system includes pump station, storage, and distribution network. An
analysis of the City's water system was conducted to identify deficiencies in the system and
recommended improvement projects to resolve the identified deficiencies. Implementation
of the improvement projects were assigned into three planning horizons: short -term from
2015 -2021, medium -term from 2022 -2025, and long -term from 2026 -2035.
The pump stations (PS) and booster pump stations (BPS) were analyzed to ensure there
was sufficient capacity to maintain the required level of service and identify improvements,
where needed. Due to capacity considerations and age, one PS will be replaced and one
PS will be decommissioned. Due to fire flow demands and reliability requirements, one BPS
will be expanded and one BPS will be replaced. Additionally, backup power will be added to
one PS.
Historically, the City has considered storage in each service area independently. New
sources and PSs increase the ability of the system to operate as an interconnected whole.
This new operational ability allows sharing of storage between the service areas and
reduces the overall need for new storage. However, the analysis of storage indicates that
the Valley Service Area will require additional storage. To meet the future storage
requirements, a combination of new storage, improvements to existing reservoirs, and
supply improvements are proposed.
The water distribution network was evaluated using demands and fire flows. To satisfy the
City's criteria, the system should be able to maintain pressures of 35 psi at all times except
during a fire. The system needs to provide fire flow under MDD conditions, while
maintaining a minimum pressure of 20 psi or greater. The velocity in transmission and
distribution mains should be less than 8 feet per second. The City's fire flow requirements
are 1,500 gpm for residential areas and 2,500 gpm for all other land use areas, except City
parks and open spaces. Hydraulic analysis showed a number of pipe improvements are
required in the future to meet the City's criteria.
ES.10 CAPITAL IMPROVEMENTS PLAN
The Capital Improvement Plan (CIP) was developed which identifies system improvements
needed to meet customer demands through the 20 year planning period. Planning -level
cost estimates were developed for each of the recommended projects for budgeting
purposes. These costs are planning level estimates only and should be refined during pre -
design of the projects. Cost estimates are presented as total project costs in October 2014
dollars.
Cost estimates were developed using a Class 5 budget estimate, as established by the
American Association of Cost Estimators (AACE). This level of estimate is used for
February 2015 — DRAFT ES -13
pw //Carollo/Documents /ClientMA/ Auburn /9466A00 /Deliverables /Executive Summary doc
strategic business planning purposes, including long -range capital planning. Planning costs
include engineering, legal, administration, and construction management costs.
Construction costs include the cost of material, labor, a 30 percent contingency, markup for
contractor overhead and profit, and sales tax on both services and materials.
The capital projects identified are categorized into water supply (S), storage (R), pump
stations (PS), distribution (D), and general improvements (G). The projects anticipated for
the next six years total $35.5M, which are summarized in Table ES.4. The project costs
shown in Table 10.7 are divided into three categories: 1) upgrade; 2) expansion; and 3)
repair and replacement. Projects may include elements of multiple categories. The City
uses this information to develop rates and System Development Charges. The total costs
for upgrade related projects over the next six years is $7.9M, the total cost for expansion
related projects over the next six years is $7.9M, and the total cost for repair and
replacement related projects over the next six years is $19.8M.
ES.11 FINANCIAL
The objective of the financial plan is to identify the total cost of providing water service and
to provide a financial program that allows the water utility to remain financially viable during
execution of the 2015 -2021 CIP. This viability analysis considers the financial condition of
the utility over the past six -year period (2008- 2013), the sufficiency of utility revenues to
meet current and future financial and policy obligations, and the financial impact of
executing the CIP.
For the 2015 -2021 planning horizon, the City identified 27 projects valued at $35.51 million
in current day dollars ($41.27 million inflated). Sources of funding to support this CIP
include revenue bonding of $34.92 million (85 percent) and cash funding of $6.35 million
(15 percent). Annual debt service for existing and bond issuances is forecasted to total
approximately $2.69 million in 2015, increasing to $4.87 million by 2021.
Operating expenses for the Utility, including annual debt service and rate - funded system
reinvestment, is forecasted to increase from approximately $13.67 million in 2015, to
$18.05 million by 2021.
To fund these financial obligations, the primary source of revenue for the utility is collections
from water service charges. Total revenues are forecasted to provide $13.85 million in 2015
and increase to $18.45 million by 2021. The forecasted revenues were developed using the
approved 3.5 percent annual increase in rates from 2015 through 2017 and an additional
average 5.7 percent annual increase starting in 2018. As a result, the financial condition is
forecasted to end 2015 with a surplus of about $171,873 increasing to approximately
$410,176 by 2021.

ES.12 MAINTENANCE AND OPERATIONS
The Maintenance and Operations (M &O) Water Division is led by the Assistant Director of
Public Works Operations, the Water Manager, Water Operations Supervisor, and the Water
Distribution Supervisor. The Water Manager is designated as the individual responsible for
the water system M &O staff. The Water Manager is designated as manager of the Water
Distribution Supervisor and Water Operations Supervisor.
The City maintains a robust communication system to contact Water Utility personnel
during normal work -hours and after - hours. This system is necessary to respond to
customer requests, routine maintenance, or emergency situations. Maintenance staff
vehicles and other rolling stock are all equipped with radios and personnel carry cellular
phones. The Water Utility also has access to an inventory of portable emergency use radio
units should they be required.
Primary operation of the City's Water System is maintained via the SCADA computerized
control system. A software program called "Wonderware" works in association with SCADA
to provide real time graphical display of system data for staff monitoring and control. The
City's SCADA system is located in the Public Works M &O Building, and responsibility for
the system falls under the Water Operations Manager and associated staff.
The Water Operations Division maintains an active and ongoing program of water quality
monitoring and reporting to ensure a safe, high quality water supply. Two staff members are
responsible for water quality monitoring, sampling, control, and record keeping. The Water
Operations Division also receives assistance from the Engineering Services - Water Quality
Program Coordinator.
The City's Public Works Department has prepared a Public Works Emergency Response
Manual as a guide for management of emergency situations. The manual is a valuable tool
for responding to emergency situations. The primary objectives of the Manual are the
protection of life and property and restoration of essential services.
