Summary Title: FY 2018 Wastewater Collection Financial Plan and Rate
Proposals
Title: Utilities Advisory Commission Recommendation That the City Council
Adopt a Resolution Approving the Fiscal Year 2018 Wastewater Collection
Financial Plan
From: City Manager
Lead Department: Utilities
Recommendation
Staff and the Utilities Advisory Commission (UAC) request that the Finance Committee
recommend that the Council:
1. Adopt a resolution (Attachment A) approving the fiscal year (FY) 2018 Wastewater
Collection Financial Plan (Attachment B);
Executive Summary
The FY 2018 Wastewater Collection Utility Financial Plan includes projections of the utility’s
costs and revenues through FY 2027. Treatment costs are projected to rise substantially over
the forecast period due to increasing operating costs and capital replacement needs at the
Regional Water Quality Control Plant, as well as gradually increasing capital and operating cost
increases for the wastewater collection system. However, this utility’s Operating Reserves are
higher than required by the reserve guidelines due to a one-time savings resulting from delays
in the utility’s annual main replacement program. As a result, staff projects the need for no
wastewater rate increase in FY 2018. Rate increases of 7% are projected for FY 2019 through FY
2023. Rates for FY 2024 and beyond are projected to increase by 3 to 5%.
The UAC reviewed the Wastewater Collection Financial Plan and Rate Proposals at its meeting
on March 1, 2017, and unanimously recommended approval of the proposed financial plan.
Background
Every year staff presents the Financial Plans for its Electric, Gas, Water, and Wastewater
Collection Utilities and recommends any rate adjustments required to maintain their financial
health. These Financial Plans include a comprehensive overview of the utility’s operations,
City of Palo Alto Page 2
both retrospective and prospective, and are intended to be a reference for UAC and Council
members as they review the budget and staff’s rate recommendations. Each Financial Plan also
contains a set of Reserves Management Practices describing the reserves for each utility and
the management practices for those reserves.
The Finance Committee reviewed preliminary financial forecasts at its March 21, 2017 meeting.
Staff has not revised the preliminary projections presented at that meeting.
Discussion
Staff’s annual assessment of the financial position of the City’s wastewater collection utility is
completed to ensure adequate revenue to fund operations, in compliance with the cost of
service requirements set forth in the California Constitution (Proposition 218). This includes
making long-term projections of market conditions, the physical condition of the system, and
other factors that could affect utility costs, and setting rates adequate to recover these costs.
The current rates are based on the methodology described in the 2011 Wastewater Collection
Utility Cost of Service and Rate Study completed by Utility Financial Solutions (Staff Report
1399).
Proposed Actions for FY 2018
1. No rate increase
These proposed actions are described in more detail in the FY 2018 Wastewater Collection
Financial Plan (Attachment B).
Staff proposes no adjustments to wastewater rates at this time. Current rates are shown in
Table 1 below.

continues to maintain it in case there is a need for the rate schedule in the
future.
FY 2018 Financial Plan’s Projected Rate Adjustments for the Next Five Fiscal Years
Table 2 shows the projected rate adjustments included in the Wastewater Collection Utility
Financial Plans and their impact on a residential wastewater bill.

FY 2018 FY 2019 FY 2020 FY 2021 FY 2022
Wastewater Utility 0% 7% 7% 7% 7%
Estimated Bill Impact for
Residential Customers ($/mo) $- $2.44 $2.61 $2.79 $2.99
The main drivers for the increase in the Wastewater Collection Utility’s costs (and therefore
rates) over the next several years are the costs for wastewater treatment, which are projected
to go up by 5 to 6% per year as the Regional Water Quality Control Plant makes several
upgrades to their facilities, as well as capital improvement costs for the wastewater collection
system. Operating and CIP costs are projected to rise roughly 2%-4% annually.
As mentioned above, staff is not proposing a rate increase for FY 2018 because the Wastewater
Collection Utility’s Operations Reserve is well above the target level set forth in the Reserve
Guidelines. The Operations Reserve is projected to be $5.3 million, as compared to the reserve
target of $4.6 million. Wastewater main replacement projects are temporarily delayed for a
variety of reasons: The University Avenue Business District project is taking longer to coordinate
than planned; fewer, more expensive competitive bidders on proposed projects have required
staff to re-plan those projects; and hiring and retention of qualified staff has been an issue.
There is uncertainty related to capital costs for the Wastewater Collection Utility in coming
years. Wastewater main replacement costs have risen substantially in recent years, and it is
possible higher CIP expenditures will be required in the future.

Commission Review and Recommendation
The UAC reviewed this proposal at its March 1, 2017 meeting. Staff noted that the rate
projection had changed since the February 1, 2017 meeting, as a further review of Operations
reserves indicated a 2% increase was not required at this time.
After the presentation, the UAC voted to recommend that the Council adopt the resolution
approving the FY 2018 Wastewater Collection Financial Plan. The vote was unanimous (7-0).
The draft excerpted minutes from the UAC’s March 1, 2017 meeting are provided as
Attachment C.
Timeline
City of Palo Alto Page 5
As no rate changes are being proposed at this time, no public noticing is required by Article
XIIID of the State Constitution (added by Proposition 218). The proposed Financial Plan will be
considered by the City Council with the FY 2018 budget.
Resource Impact
See the FY 2018 Wastewater Collection Utility Financial Plan (Attachment B) for a more
comprehensive overview of projected cost and revenue changes for the next five years.
Policy Implications
The proposed Wastewater Collection Financial Plan is consistent with Council-adopted Reserve
Management Practices.
Environmental Review
The Finance Committee’s review and recommendation to Council on the proposed FY 2018
Wastewater Collection Financial Plan does not meet the definition of a project requiring
California Environmental Quality Act (CEQA) review, under California Public Resources Code
21065 and CEQA Guidelines Section 15378(b)(5), because it is an administrative governmental
activity which will not cause a direct or indirect physical change in the environment.

Resolution No. ____
Resolution of the Council of the City of Palo Alto Approving the
FY 2018 Wastewater Collection Utility Financial Plan
R E C I T A L S
A. Each year the City of Palo Alto (“City”) assesses the financial position of its utilities
with the goal of ensuring adequate revenue to fund operations. This includes making long-term
projections of market conditions, the physical condition of the system, and other factors that
could affect utility costs, and setting rates adequate to recover these costs. It does this with the
goal of providing safe, reliable, and sustainable utility services at competitive rates. The City
adopts Financial Plans to summarize these projections.
B. The City uses reserves to protect against contingencies and to manage other aspects
of its operations, and regularly assesses the adequacy of these reserves and the management
practices governing their operation. The status of utility reserves and their management
practices are included in Reserves Management Practices attached to and made a part of the
Financial Plans.
The Council of the City of Palo Alto does hereby RESOLVE as follows:
SECTION 1. The Council hereby approves the FY 2018 Wastewater Collection Utility
Financial Plan.
SECTION 2. The Council finds that the adoption of this resolution does not meet the
definition of a project requiring California Environmental Quality Act (CEQA) review, under

SECTION 2: EXECUTIVE SUMMARY AND RECOMMENDATIONS
This document presents a Financial Plan for the City of Palo Alto’s Wastewater Collection Utility
for the next ten years. The Financial Plan provides revenues to cover the costs of operating the
utility safely over that time while adequately investing for the future. It also addresses the
financial risks facing the utility over the short term and long term, and includes measures to
mitigate and manage those risks.
SECTION 2A: OVERVIEW OF FINANCIAL POSITION
Overall costs in the Wastewater Collection Utility are expected to rise by about 6% per year
from fiscal year (FY) 2017 to FY 2027. Excluding FY 2018 (which, unlike a normal year, does not
include a sewer main replacement project), wastewater treatment and CIP costs are projected
to rise by five to six percent annually through the projection period, with other costs rising at
roughly three percent per year. The costs for the Wastewater Collection Utility are shown in
Table 1 below.

year’s financial plan. Going forward, to ensure that revenues cover rising costs and reserves
remain healthy, the financial plan includes the rate trajectory shown in Table 2. The table also
shows rate projections from last year’s Financial Plan. Last year’s plan projected earlier, more
aggressive rate increases. However, the delay of the planned FY 2017 and FY 2018 sewer main
replacement projects resulted in an increase in reserves, which enabled the more gradual
increases projected in the current plan.

The Wastewater Collection Utility has a small balance in its Rate Stabilization Reserve. This
reserve is used to phase in rate increases over several years. The FY 2017 Financial Plan
proposed a $342,000 transfer from the Rate Stabilization Reserve, but in the proposed FY 2018
Financial Plan this transfer is moved to later years. Due to the delays in main replacement
noted above, the Operations reserve is above its target level, and will rise again in FY 2018
before beginning to decline. This Financial Plan projects that the Rate Stabilization Reserve will
not be needed until FY 2020.

SECTION 2B: SUMMARY OF PROPOSED ACTIONS
Staff proposes no rate changes or transfers for the Wastewater Collection Utility in FY 2017 and
FY 2018.
SECTION 3: DETAIL OF FY 2018 RATE AND RESERVES PROPOSALS
SECTION 3A: RATE DESIGN
The Wastewater Collection Utility’s rates are evaluated and implemented in compliance with
the cost of service requirements and procedural rules set forth in the California Constitution
(Proposition 218). Current rates were structured based on staff’s annual assessment of the
wastewater utility’s financial position, as well as the methodology from the January 2011
Wastewater Collection Utility Cost of Service & Rate Study completed by Utility Financial
Solutions (Staff Report 1399). Staff plans to review and update this cost of service study in FY
2018 or FY 2019, unless any major changes occur to the utility’s operations or customer base
that would necessitate an earlier study. Before conducting any new cost of service study, staff
will review current rates and the scope of the study with the Utilities Advisory Commission
(UAC) and Council to determine the City’s policy priorities.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 6 | Page
SECTION 3B: CURRENT AND PROPOSED RATES
The current rates were adopted July 1, 2016, when the City increased sewer rates by 9%.
CPAU has three sewer rate schedules: one for residents (S-1), one for commercial customers
(S-2), and a special schedule for restaurants (S-6), which discharge higher than average amounts
of grease and oil and, therefore, have a greater impact on the sewer system. Residential
customers are billed a monthly service charge, while commercial customers are billed based on
their dry month water usage (previous January through March). This closely approximates non-
irrigation water consumption, which represents actual sewer use. Restaurant customers are
billed monthly based on water usage. CPAU also maintains a rate schedule for industrial
dischargers (S-7), but there are currently no customers required to be on this rate schedule.
CPAU us not proposing any rate changes for FY 2018 at this time. Table 4, below, summarizes
the current rates for all customer classes. Comparisons with neighboring communities are
discussed in Section 4F: Competitiveness.

S-2 (Commercial) $/CCF 6.71
S-6 (Restaurant) $/CCF 10.38
S-7 (Industrial) $/CCF 3.08
SECTION 3C: PROPOSED RESERVE TRANSFERS
In the FY 2017 Financial Plan, staff recommended a $1.95 million transfer from the Rate
Stabilization Reserve in FY 2016. This left a small amount, $342,000, which was originally to be
transferred in FY 2017 and bring the Rate Stabilization Reserve balance to zero.
With main replacement projects being deferred in FY 2017 and FY 2018, the Operations reserve
will not require a transfer from the Rate Stabilization Reserve. It is now anticipated that the
remaining $342,000 will not need to be transferred until FY 2020.
These transfers are included in the financial projections in this Financial Plan, and will enable
CPAU to maintain adequate Operations Reserve levels while moderating the pace of increase in
Wastewater Collection rates. The impact of these transfers on reserves levels can be seen in
Appendix A: Wastewater Collection Financial Forecast Detail.

SECTION 4: UTILITY OVERVIEW
This section provides an overview of the utility and its operations. It is intended as general
background information and to help readers better understand the forecasts in later sections.
SECTION 4A: WASTEWATER UTILITY HISTORY
The Wastewater Utility commenced operation in 1899 to serve Palo Alto and Stanford. In its
first three decades the system grew to 60 miles of sewers. Raw sewage was discharged into
Mayfield Slough at the edge of the Bay. In the 1930s, at the behest of the State Department of
Health, Palo Alto built the South Bay’s first wastewater treatment plant. At that time the sewer
system served 20,500 Stanford and Palo Alto residents and a cannery. The plant was upgraded
twice in the 1940s and 1950s to increase capacity.1 At the same time, the postwar population
and industrial boom in the 1950s required rapid expansion of the sewer system. In the first half
of the 1960s Palo Alto’s area doubled, as did wastewater flows, overwhelming the capacity of
several of the utility’s “trunk lines,” which are the largest diameter main sewer lines carrying
wastewater to the treatment plant. This prompted the City, in 1965, to perform the first of its
sewer master plans to identify needed capacity improvements. At that point the Wastewater
Utility’s system comprised more than 150 miles of sewer mains.2
In 1968 the City signed agreements with the Cities of Mountain View and Los Altos to build a
new regional treatment plant, the RWQCP, which is still in operation today. Since 1940 the City
had been providing treatment services to the East Palo Alto Sanitary District through an existing
agreement, and was also serving Stanford University by transporting wastewater across the
City’s sewer system to the treatment plant. Both of these organizations became partners in the
RWQCP as well. At the same time the Town of Los Altos Hills became the sixth partner as it
signed an agreement with the City to connect the Town’s sewer system to the City’s sewer
system to carry wastewater to the new RWQCP. The current agreements for the RWQCP
extend through 2035.3
In the 1980s the City directed increased attention to the condition of its sewer system,
performing a series of studies of groundwater inflow and infiltration into the system. The
studies found high rates of infiltration, estimating that as much as 40% of the water going to
the RWQCP from Palo Alto’s system was groundwater and stormwater rather than
wastewater.4 In some parts of Palo Alto the land surface had subsided due to groundwater
pumping by the water utility, and though that practice had ceased many years earlier as the
water utility switched to the Hetch Hetchy Regional Water System, parts of the city had already
subsided two to five feet. This subsidence had damaged several parts of the sewer collection
system, leading to reduced slopes for sewer mains that caused reductions in capacity. In

WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 8 | Page
response to these studies the City commenced an accelerated sewer system rehabilitation
program.5 At that point the sewer system comprised over 190 miles of mains.6
A Master Plan study in 1988 recommended a variety of capacity expansions, and in the 1990s
the City completed about half of them. However, a 2004 Master Plan update found that the
accelerated sewer rehabilitation plan started in the early 1990s had substantially reduced
infiltration, easing the capacity problems that had led the to the recommended capacity
increases in the 1988 study. Several of the outstanding projects were canceled and replaced
with a different set of projects.7 At the same time the City updated its hydraulic model and
developed greater capacity to do system planning in house.
SECTION 4B: CUSTOMER BASE
The City of Palo Alto’s Wastewater Collection Utility provides sewer service to the residents and
businesses of Palo Alto. It is distinct from the Wastewater Treatment Utility, which provides
treatment services for surrounding communities in addition to Palo Alto. Nearly 23,300
customers are connected to the sewer system, approximately 21,450 (92%) of which are
residential and 1,850 (8%) of which are non-residential. Residential customers pay a flat fee for
service. Non-residential customers are billed for sewer service based on their metered winter
water usage. There is little variability in revenues for this utility.
SECTION 4C: COLLECTION SYSTEM
The Wastewater Collection Utility delivers all the wastewater it collects to the Regional Water
Quality Control Plant (RWQCP) operated by the City of Palo Alto under a partnership agreement
with several surrounding communities. Palo Alto is responsible for 35% to 40% of the
wastewater sent to the RWQCP. The cost of running the RWQCP is contained in the
Wastewater Treatment Utility and is not described in detail in this Financial Plan, but since
these costs are a major driver of CPAU’s sewer rates, there is some discussion of future trends
in treatment costs in Section 6A: Wastewater Treatment Costs. Treatment costs make up
nearly half of the Wastewater Collection Utility’s expenses as shown in Table 1 above.
To collect wastewater from its customers and deliver it to the RWQCP, CPAU owns roughly
18,100 sewer laterals (which collect wastewater from customers’ plumbing systems) and 217
miles of sewer mains (which transport the waste to the treatment plant). These laterals and
mains, along with the associated manholes and cleanouts, represent the vast majority of
infrastructure used to collect wastewater in Palo Alto. CPAU conducts a sewer rehabilitation
and replacement program to replace mains over time as they deteriorate or to increase
capacity. For more discussion of this program, see Section 6C: Capital Improvement Program
(CIP). CIP expense accounts for roughly a quarter of the utility’s expenditures.
In addition to its CIP, CPAU performs various maintenance activities on the sewer system.
These include inspecting and repairing sewer laterals, responding to sewer overflows, regularly

WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 9 | Page
cleaning sections of the system heavily impacted by fats, oils, and grease (FOG), and building
and replacing sewer laterals for new or redeveloped buildings. The utility also shares the costs
of other operational activities (such as customer service, billing, equipment maintenance, and
street restoration) with the City’s other utilities. These maintenance and operations expenses,
as well as associated administration, debt service, rent, and other costs, make up another
quarter of the utility’s expenses.
SECTION 4D: COST STRUCTURE AND REVENUE SOURCES
In FY 2016, treatment costs represented nearly half of the Wastewater Collection Utility’s costs
(47%), followed by Capital (27%) and Operations costs (26%). These expenditures are shown in
Figure 1. The utility’s revenue in FY 2016, shown in Figure 2, came primarily from sewer charges
(94%), with the remainder coming mainly from capacity and connection fees and other sources
(6%).
Figure 1: Cost Structure (FY 2016) Figure 2: Revenue Structure (FY 2016)
SECTION 4E: RESERVES STRUCTURE
CPAU maintains six reserves for its Wastewater Collection Utility to manage various types of
contingencies. These are summarized below, but see Appendix C: Wastewater Collection Utility
Reserves Management Practices for more detailed definitions and guidelines for reserve
management:
• Reserve for Commitments: A reserve equal to the utility’s outstanding contract
liabilities for the current fiscal year. Most City funds, including the General Fund, have a
Commitments Reserve.
• Reserve for Reappropriations: A reserve for funds dedicated to projects reappropriated
by the City Council, nearly all of which are capital projects. Most City funds, including
the General Fund, have a Reappropriations Reserve.
• Capital Improvement Program (CIP) Reserve: The CIP reserve can be used to
accumulate funds for future expenditure on CIP projects and is anticipated to be empty
unless a major one-time CIP expenditure is expected in future years. It also acts as a
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 10 | Page
contingency reserve for the CIP. This type of reserve is used in other utility funds
(Electric, Gas, and Water) as well.
• Rate Stabilization Reserve: This reserve is intended to be empty unless one or more
large rate increases are anticipated in the forecast period. In that case, funds can be
accumulated to spread the impact of those future rate increases across multiple years.
This type of reserve is used in other utility funds (Electric, Gas, and Water) as well.
• Operations Reserve: This is the primary contingency reserve for the Wastewater
Collection Utility, and is used to manage yearly variances from budget for operational
costs. This type of reserve is used in other utility funds (Electric, Gas, and Water) as well.
• Unassigned Reserve: This reserve is for any funds not assigned to the other reserves
and is normally empty.
SECTION 4F: COMPETITIVENESS
Table 6 shows the monthly sewer bills for residential customers compared to what they would
be in surrounding communities. The annual sewer bill for a Palo Alto customer is $418 under
current rates, 31% lower than the average neighboring community. Palo Alto has the fourth
lowest bill of the group.

Table 7 compares the sewer bills for two classes of commercial customers to what they would
be under surrounding communities’ rate schedules. Note that other communities often have
specific rates for industrial customers that discharge high intensity wastewater, such as food
processors or chemical or electronics manufacturers, but Palo Alto does not currently have any
customers that require these special rates. Palo Alto is less competitive with surrounding cities
with regards to commercial sewer rates, but is not the most expensive jurisdiction in all cases.

SECTION 5: UTILITY FINANCIAL PROJECTIONS
SECTION 5A: FY 2012 TO FY 2016 COST AND REVENUE TRENDS
Figure 3 shows the Wastewater Collection Utility’s actual expenses and revenues for the past
five years and projections through FY 2027. Operations costs were low in FY 2012, but in
general expenses have grown with inflation at around 2% per year. Capital Investment grew on
average by around 3%, with FY 2014 and FY 2015 seeing a reduction in investment mainly due
to delayed main replacement projects. Treatment costs stayed relatively flat during this time
frame.
Since the revenue for this utility is very stable, revenue changes closely follow rate changes. The
other large revenue item of note is the continued connection and capacity fees from new
construction. These fees have grown dramatically since FY 2010, and it is uncertain when this
trend may dampen.

Actual Costs through FY 2016 and Projections through FY 2027
SECTION 5B: FY 2016 RESULTS
Forecasted revenues for FY 2016 were lower than projected ($16.6 million actual vs. $18 million
projected), but expenses related to Administration and Customer Service activities came in well
below expected budget as well. Total FY 2016 expenses were $18.5 million compared to
projections of $19.9 million in the FY 2017 Financial Plan. Table 8 summarizes the variances
from forecast.

SECTION 5C: FY 2017 PROJECTIONS
The most notable change from the FY 2017 budget identified at this time is the deferral of
Wastewater Collection System Rehabilitation Project 28. Originally budgeted at $3.5 million,
this project is now anticipated to start in FY 2019. Also deferred to FY 2019 will be the design
phase of Project 29, budgeted at $328,000. Capital Improvement issues are further discussed in
Section 6c below.
SECTION 5D: FY 2018 – FY 2027 PROJECTIONS
Staff has prepared a forecast of costs and revenues through FY 2027. As shown in Figure 3
above (and, in more detail, in Appendix A: Wastewater Collection Financial Forecast Detail), the
Wastewater Collection Utility’s total costs are projected to increase by roughly 6% per year on
average for FY 2017 through FY 2027. The majority of this increase is due to projected
treatment cost increases. The treatment plant itself is facing the need for major upgrades in
coming years, both due to age of equipment and constantly changing environmental
regulations. While the costs of the plant are shared among member agencies, Palo Alto is still
expected to see average cost increases of 5% per year over the forecast horizon.
Revenues are shown by the red line in Figure 3, and what is notable here is that costs have
been generally higher than revenue. Some relief was experienced during times of lower CIP
expenditures, and this is projected to be seen in FY 2017 and 2018. The trend of under-
collection picks up in the future, however, resulting in a fairly rapid reduction of reserves. A
path of 7% annual rate increases in the near term, decreasing to more inflationary increases in
outer years, is required to keep reserves from dropping too low. Figure 4 below shows the
relative drop in reserves, only showing slowing replenishment after the projected increase in FY
2021.

SECTION 5E: RISK ASSESSMENT AND RESERVES ADEQUACY
The Wastewater Collection Utility currently has one contingency reserve, the Operations
Reserve, and this Financial Plan maintains reserves within the approved guideline levels
throughout the forecast period, as shown in Figure 5 below. Reserve levels also exceed the
short term risk assessment for the utility.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 15 | Page
Figure 5: Operations Reserve Adequacy
Staff performs an annual assessment of risks for the Wastewater Collection Utility. For this
evaluation, staff estimates the revenue shortfall due to:
1. the maximum observed budget-to-actual variance in one year during the past five years;
2. an increase of 10% in system improvement CIP expenditures for the year; and
3. an increase of 10% in treatment costs.
Table 9 summarizes the risk assessment calculation for the Wastewater Collection Utility
through FY 2022. The Operations Reserve is projected to be adequate to manage these levels
of risk over the entire forecast period.

SECTION 5F: ALTERNATE SCENARIOS
At its February 2017 meeting, staff presented an earlier scenario with a 2% rate increase in FY
2018 followed by 6% rate increases in outer years. However, with the Operations reserve
projected to be above the target level and well within the guideline levels adopted by Council,
staff no longer sees the need for an increase at this time.
SECTION 5G: LONG-TERM OUTLOOK
In the longer term (5 to 35 years) the primary factor that could lead to increased costs for the
Wastewater Collection Utility are major upgrades at the RWQCP, a share of which will be
allocated to the utility as part of treatment costs. These upgrades includes replacement or
rehabilitation of the parts of the facility that pump raw sewage to the main treatment works
(the headworks), separate out primary sludge (the primary settling tank), process sludge (the
bio-solids facility), and treat wastewater (the fixed film reactors). Upgrades to the laboratories
and operational buildings are planned as well. In addition, the 72-inch regional trunk sewer line
flowing into the plant needs to be evaluated and rehabilitated.
SECTION 6: DETAILS AND ASSUMPTIONS
SECTION 6A: WASTEWATER TREATMENT COSTS
Treatment expenses represent the Wastewater Collection Utility’s share of the costs of
operating the RWQCP. Per the partnership agreements between Palo Alto and its partner
agencies, these charges are assessed based on a formula that takes into account the total
amount of wastewater delivered, the amount of organic material in it, its ammonia content,
and the total suspended solids it is carrying. The Wastewater Collection Utility’s assessed share
of the RWQCP’s revenue requirement fluctuates in the 38% to 40% range. Mountain View is
the other large agency served by the RWQCP (39% of the revenue requirement for FY 2014)
with the smaller agencies (Stanford, Los Altos, East Palo Alto, and Los Altos Hills) making up the
remainder of the flow to the treatment plant.
Based on detailed project cost projections provided by RWQCP staff, treatment costs are likely
to continue to increase by roughly 5% per year through at least 2030. Wastewater Treatment
Fund costs are increasing due to rising salary and benefit costs as well as the attendant
allocated charges for centralized city services needed by the Fund. Additional expenses include
increased water and air permitting fees from the Regional Water Quality Control Board and the
Bay Area Air Quality Management District. Commodity and utility rates to operate the facility
are also increasing with the largest increases in FY2018 for electrical, water, refuse, and storm
rates. Chemical commodity expenses, needed to adjust water quality and meet permit
requirements, are also increasing modestly per latest chemical market conditions and
procurement contract conditions.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 17 | Page
Capital projects, parts, and materials are increasing about 3% to keep up with ongoing
replacement of aging equipment. Larger increase to capital expenses are expected to begin in
FY2020 in the form of new debt service for major projects to implement the Plant’s capital
program. The Plant’s major project in FY2018 will be making progress constructing the Sludge
Dewatering and Truck Loadout Facility, which will allow (in about 2019) the retirement of the
Plant’s two sewage sludge incinerators that have been in operation since 1972.
SECTION 6B: OPERATIONS
Operations costs include the Customer Service, Distribution Operations, Engineering, and
Allocated Charges categories in Appendix A: Wastewater Collection Financial Forecast Detail.
Debt service, rent, and transfers are also included in this category. Customer Service costs are
primarily related to the call center and collections on delinquent accounts. The Distribution
Operations category includes preventative and corrective maintenance on sewer mains and
laterals, investigation of sewer overflows, regular cleaning of heavily impacted sections of the
sewer system, and services shared with other utilities (such as street restoration and
equipment maintenance). Allocated Charges include the costs of accounting, purchasing, legal,
and other administrative functions provided by the City’s General Fund staff, as well as shared
communications services and Utilities Department administrative overhead and billing system
maintenance costs.
Operations costs are projected to increase by 3% per year, on average, over the forecast period.
Underlying these projections are salary and benefit, consumer price index, and other cost
projections used in the City’s long-range financial forecast.
SECTION 6C: CAPITAL IMPROVEMENT PROGRAM (CIP)
The Wastewater Collection Utility’s CIP consists of the following programs:
• The Sewer System Replacement/Rehabilitation Program, under which the Wastewater
Collection Utility replaces aging sewer mains.
• Customer Connections, which covers the cost when the Wastewater Collection Utility
installs new services or upgrades existing services at a customer’s request in response
to development or redevelopment. CPAU charges a fee to these customers to cover
the cost of these projects.
• Ongoing Projects, which covers the cost of replacing degraded manholes and sewer
laterals, as well as the cost of capitalized tools and equipment.
The Sewer System Replacement and Rehabilitation Program funds the replacement of
deteriorating sewer mains and projects to increase capacity in various parts of the sewer
system. The sewer system consists of over 217 miles of mains, and CPAU uses a variety of tools
to establish which sections are in need of replacement. Maintenance statistics (such as records
of the location and number of sewer overflows on the system) and videotape of sewer mains
during regular cleaning can reveal areas with large amounts of deteriorating pipe. CPAU uses a
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 18 | Page
scoring system to prioritize which mains to replace first, and coordinates with the Public Works
street maintenance program to avoid cutting into newly repaved streets. A major goal of the
program is to minimize groundwater and rainwater infiltration. As mains deteriorate they
begin to allow groundwater and rainwater to infiltrate the system. Some level of infiltration is
expected on any sewer system, but if there is too much, the combined flow of wastewater and
groundwater/rainwater can overwhelm the capacity of various parts of the sewer system.
Reducing infiltration can reduce the need to expand the system to accommodate increased
flow. To achieve this goal, deteriorating mains are either repaired with a plastic lining or
replaced. CPAU replaces or repairs approximately 25,000 feet of main per year, or 2.5% of the
system.
The CIP program also funds sewer capacity improvements. CPAU uses a hydraulic model, data
from various flow meters on the system, and land use data to identify sections of the system
that are being overloaded. When sewer mains are operating at or above their capacity on a
regular basis it will increase the likelihood of sewer overflows. CPAU also does occasional
comprehensive master planning studies to identify necessary capacity improvements. The most
recent study, in 2004, identified eight projects, three of which have been completed. The
remaining four projects are low priority projects and will be scheduled and planned as the need
arises.
Over the last few years, main replacement costs have been increasing for Wastewater as well
as the Gas and Water utilities. The replacement cost per linear foot has increased by between
25 and 50% in some cases. Several factors may be contributing to this. Economic recovery in
the Bay Area, as well as a greater focus on infrastructure improvement by many municipal
agencies and utilities could be creating high demand for contractors in this field. There may be
ongoing greater costs for newer, more leak resistant pipe materials. Should these trends prove
to be less than short-term phenomena, wastewater main replacement budgets may need to be
increased by $1.5 to $1.7 million more per year to maintain the current pace of replacement.
This increase in cost is a partial reason for the two year delay in projects. The most recent
project, when put out for bid, resulted in very few contractors competing, and project bids
larger than budgeted. Staff will redesign this and future projects into smaller segments to keep
budgets lower, while not compromising on overall system integrity. The other reason for delay
is the University Avenue Business District project, and getting coordination amongst all
departments is taking more time than expected. Finally, there has been an ongoing issue with
keeping and maintaining qualified staff to design and work on projects.
Customer Connections costs are projected to increase steadily by around 3% each year through
the end of the forecast period. Actual expenses for these projects fluctuate annually depending
on how many defective laterals and manholes are discovered during routine maintenance, as
well as how much development and redevelopment is going on that prompts the replacement
or upgrade of sewer laterals. It is worth noting that property owners pay a fee for sewer lateral
replacement or expansion during redevelopment, so when the number of projects increases, so
does fee revenue.
Projected CIP spending is displayed in Table 10 for the 5-year financial forecast period.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 19 | Page
Table 9: Projected CIP Spending
Aside from Customer Connections, the CIP plan for FY 2018 to FY 2022 is funded by sewer rates
and capacity fees. The details of the plan are shown in Appendix B: Wastewater Collection
Utility Capital Improvement Program (CIP) Detail.
SECTION 6D: DEBT SERVICE
The Wastewater Collection Utility currently pays its share of one bond issuance, the 1999 Utility
Revenue Bonds, Series A, which is due to be retired in 2024. This $17.7 million issuance
refinanced various earlier Storm Drain, Wastewater Treatment, and Wastewater Collection
Utility bond issuances. The Wastewater Collection Utility’s share of the issuance was roughly
$1.9 million. This amount represented the second refinancing of the remaining principal of a
1990 bond issuance which itself was a refinancing of a 1985 issuance that financed a variety of
improvements to the sewer system. The cost of debt service for the Wastewater Collection
Utility’s share of this bond issuance for the financial forecast period is roughly $128,000 per
year as shown in Table 11 below.

1999 Utility Revenue Bonds, Series A 128 128 128 129 129 129
The 1999 Utility Revenue Bonds include two covenants stating that 1) the Wastewater
Collection Utility will maintain a debt coverage ratio of 125% of debt service, and 2) that the
City will maintain “Available Reserves”8 equal to five times the annual debt service. The current
financial plan maintains compliance with both covenants throughout the forecast period.
Compliance with covenant one is shown below in Table 12, below. Due to the small size of the
annual debt service payment for these bonds, the Wastewater Collection Utility’s Operations
Reserve alone more than satisfies the second covenant at more than 30 times annual debt
service throughout the forecast period.
8 Available Reserves as defined in the 1999 Utility Revenue Bonds included reserves for the Water, Wastewater
Treatment, Wastewater Collection, Refuse, Storm Drain, Electric, and Gas Utilities
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 20 | Page
Table 11: Debt Service Coverage Ratio ($000)

Coverage Ratio 2479% 2363% 2866% 3186% 3407% 4084%
The Wastewater Collection Utility’s reserves (but not its net revenues) are also considered
security for the Storm Drain and Wastewater Treatment Utilities’ shares of the debt service on
the 1999 bonds. Throughout the term of the bonds there remains a small risk that the
Wastewater Collection Utility’s reserves could be called upon to make a debt service payment
on behalf of one of those utilities if it cannot meet its debt service obligations. Staff does not
foresee this occurring based on the current financial condition of those utilities. If the
Wastewater Collection Utility’s reserves were used this way, any amounts advanced would
have to be repaid by the borrowing utility.
One other bond series is secured by the net revenues (but not the reserves) of the Wastewater
Collection Utility. The 1995 Series A Utility Revenue Bonds issued for the Storm Drain utility
was secured by the net revenues of the City’s “Enterprise,” which was defined as the City’s
water, gas, wastewater, storm drain, and electric utilities, and are senior to the 1999 bonds
referenced above. Debt service payments of roughly $680,000 per year are made on the 1995
Series A bonds by the City’s Storm Drain Utility, and staff does not currently foresee any risk of
that utility being unable to make payment.
SECTION 6E: OTHER REVENUES
The utility has seen substantial increases in connection and capacity fee revenues in recent
years, offsetting the need for increased sales revenue in the past, and these are assumed to
continue, albeit slightly reduced from current levels. Income from interest and transfers in are
projected to remain steady through the forecast horizon.
SECTION 7: COMMUNICATIONS PLAN
The FY 2017 Wastewater Collection Utility communications strategy covers three primary areas:
rates, maintenance and operations, and safety. Communication about wastewater rate
adjustments will highlight the important infrastructure and operations upgrades that are
occurring at the Regional Water Quality Control Plant to improve wastewater collection utility
services. To keep customers apprised of the status and accomplishments of CIP projects, a
network of project web pages are maintained and updated as needed. Traffic is driven to the
website via ads in newspapers and local publications, utility bill inserts, social media and email
newsletters.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 21 | Page
An important communications topic for the wastewater utility is avoiding sewer back-ups due
to FOG (fats, oil and grease) and trash being dumped down drains and toilets. Safety topics are
emphasized year-round. Staff continues its outreach goal of educating customers about the
utility’s gas-sewer line cross-bore inspection program, including the importance of calling
Utilities prior to clearing sewer lines in the event of a sewer back-up.
Promotional activity about wastewater utility maintenance and safety operations includes use
of bill inserts, ads in local print publications, website pages, email newsletters and social
media. While print materials and website pages feature prominently, CPAU is increasing the
outreach emphasis on more direct communication with customers, including through use of
social media, email newsletters, digital ads, videos and short commercials on the local
television channels. Staff is also attending more community safety/emergency preparation
events and neighborhood meetings.

APPENDIX C: WASTEWATER COLLECTION UTILITY RESERVES
MANAGEMENT PRACTICES
The following reserves management practices shall be used when developing the Wastewater
Collection Utility Financial Plan:
Section 1. Definitions
a) “Financial Planning Period” – The Financial Planning Period is the range of future fiscal
years covered by the Financial Plan. For example, if the Financial Plan delivered in
conjunction with the FY 2015 budget includes projections for FY 2015 to FY 2019, FY
2015 to FY 2019 would be the Financial Planning Period.
b) “Fund Balance” – As used in these Reserves Management Practices, Fund Balance refers
to the Utility’s Unrestricted Net Assets.
c) “Net Assets” - The Government Accounting Standards Board defines a Utility’s Net
Assets as the difference between its assets and liabilities.
d) “Unrestricted Net Assets” - The portion of the Utility’s Net Assets not invested in capital
assets (net of related debt) or restricted for debt service or other restricted purposes.
Section 2. Reserves
The Wastewater Collection Utility’s Fund Balance is reserved for the following purposes:
a) For existing contracts, as described in Section 3 (Reserve for Commitments)
b) For operating and capital budgets re-appropriated from previous years, as described in
Section 4 (Reserve for Re-appropriations)
c) For cash flow management and contingencies related to the Wastewater Collection
Utility’s Capital Improvement Program (CIP), as described in Section 5 (CIP Reserve)
d) For rate stabilization, as described in Section 6 (Rate Stabilization Reserve)
e) For operating contingencies, as described in Section 7 (Operations Reserve)
f) Any funds not included in the other reserves will be considered Unassigned Reserves
and shall be returned to ratepayers or assigned a specific purpose as described in
Section 8 (Unassigned Reserves).
Section 3. Reserve for Commitments
At the end of each fiscal year the Reserve for Commitments will be set to an amount equal
to the total remaining spending authority for all contracts in force for the Wastewater
Collection Utility at that time.
Section 4. Reserve for Re-appropriations
At the end of each fiscal year the Reserve for Re-appropriations will be set to an amount
equal to the amount of all remaining capital and non-capital budgets, if any, that will be re-
appropriated to the following fiscal year in accordance with Palo Alto Municipal Code
Section 2.28.090.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 26 | Page
Section 5. CIP Reserve
The CIP Reserve is used to manage cash flow for capital projects and acts as a reserve for
capital contingencies. Staff will manage the CIP Reserve according to the following
practices:
a) The following guideline levels are set forth for the CIP Reserve. These guideline levels
are calculated for each fiscal year of the Financial Planning Period based on the levels of
CIP expense budgeted for that year.
Minimum Level 12 months of budgeted CIP expense
Maximum Level 24 months of budgeted CIP expense
b) Changes in Reserves: Staff is authorized to transfer funds between the CIP Reserve and
the Reserve for Commitments when funds are added or removed from to that reserve
as a result of a change in contractual commitments related to CIP projects. Any other
additions to or withdrawals from the CIP reserve require Council action.
c) Minimum Level:
i) Funds held in the Reserve for Commitments may be counted as part of the CIP
Reserve for the purpose of determining compliance with the CIP Reserve minimum
guideline level.
ii) If, at the end of any fiscal year, the minimum guideline is not met, staff shall present
a plan to the City Council to replenish the reserve. The plan shall be delivered by the
end of the following fiscal year, and shall, at a minimum, result in the reserve
reaching its minimum level by the end of the next fiscal year. For example, if the CIP
Reserve is below its minimum level at the end of FY 2017, staff must present a plan
by June 30, 2018 to return the reserve to its minimum level by June 30, 2019. In
addition, staff may present, and the Council may adopt, an alternative plan that
takes longer than one year to replenish the reserve, or that does so in a shorter
period of time.
d) Maximum Level: If, at any time, the CIP Reserve reaches its maximum level, no funds
may be added to this reserve. If there are funds in this reserve in excess of the
maximum level staff must propose to transfer these funds to another reserve or return
them to ratepayers in the next Financial Plan. Staff may also seek City Council to
approve holding funds in this reserve in excess of the maximum level if they are held for
a specific future purpose related to the CIP.
Section 6. Rate Stabilization Reserve
Funds may be added to the Rate Stabilization Reserve by action of the City Council and held
to manage the trajectory of future year rate increases. Withdrawal of funds from the Rate
Stabilization Reserve requires Council action. If there are funds in the Rate Stabilization
Reserve at the end of any fiscal year, any subsequent Wastewater Collection Utility
Financial Plan must result in the withdrawal of all funds from this Reserve by the end of the
Financial Planning Period.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
February 2016 27 | Page
Section 7. Operations Reserve
The Operations Reserve is used to manage normal variations in costs and as a reserve for
contingencies. Any portion of the Wastewater Collection Utility’s Fund Balance not
included in the reserves described in Section 3-Section 6 above will be included in the
Operations Reserve unless this reserve has reached its maximum level as set forth in Section
7(d) below. Staff will manage the Operations Reserve according to the following practices:
a) The following guideline levels are set forth for the Operations Reserve. These guideline
levels are calculated for each fiscal year of the Financial Planning Period based on the
levels of Operations and Maintenance (O&M) and commodity expense forecasted for
that year in the Financial Plan.
Minimum Level 60 days of O&M and commodity expense
Target Level 105 days of O&M and commodity expense
Maximum Level 150 days of O&M and commodity expense
b) Minimum Level: If, at the end of any fiscal year, the funds remaining in the Operations
Reserve are lower than the minimum level set forth above, staff shall present a plan to
the City Council to replenish the reserve. The plan shall be delivered within six months
of the end of the fiscal year, and shall, at a minimum, result in the reserve reaching its
minimum level by the end of the following fiscal year. For example, if the Operations
Reserve is below its minimum level at the end of FY 2014, staff must present a plan by
December 31, 2014 to return the reserve to its minimum level by June 30, 2015. In
addition, staff may present, and the Council may adopt, an alternative plan that takes
longer than one year to replenish the reserve.
c) Target Level: If, at the end of any fiscal year, the Operations Reserve is higher or lower
than the target level, any Financial Plan created for the Wastewater Collection Utility
shall be designed to return the Operations Reserve to its target level within four years.
d) Maximum Level: If, at any time, the Operations Reserve reaches its maximum level, no
funds may be added to this reserve. Any further increase in the Wastewater Collection
Utility’s Fund Balance shall be automatically included in the Unassigned Reserve
described in Section 8, below.
Section 8. Unassigned Reserve
If the Operations Reserve reaches its maximum level, any further additions to the
Wastewater Collection Utility’s Fund Balance will be held in the Unassigned Reserve. If
there are any funds in the Unassigned Reserve at the end of any fiscal year, the next
Financial Plan presented to the City Council must include a plan to assign them to a specific
purpose or return them to the Wastewater Collection Utility ratepayers by the end of the
first fiscal year of the next Financial Planning Period. For example, if there were funds in the
Unassigned Reserves at the end of FY 2015, and the next Financial Planning Period is
FY 2016 through FY 2020, the Financial Plan shall include a plan to return or assign any
funds in the Unassigned Reserve by the end of FY 2016. Staff may present an alternative
plan that retains these funds or returns them over a longer period of time.

UTILITIES ADVISORY COMMISSION
ITEM 4. ACTION: Staff Recommendation that the Utilities Advisory Commission Recommend
that the City Council Adopt: (1) a Resolution Approving the Fiscal Year 2018 Wastewater
Collection Financial Plan
Acting Senior Resource Planner Eric Keniston presented on the Wastewater Collection Financial
Plan. He said no rate increase was proposed for the Wastewater Collection Utility. Wastewater
collection capital investment was projected to increase in the future, and wastewater
treatment capital investment and operating costs were projected to increase in the future.
Commissioner Trumbull noted citizens were voting for a parcel tax to extend the storm drain.
He asked whether that was reflected in the summary of all rate increases shown in the staff
presentation, and what the impact to residential rates would be if the parcel tax were not
approved.
Keniston said that the numbers were provided for context, but staff did not have information
on hand to address the storm drain rate changes.
Assistant Director of Resource Management Jonathan Abendschein said the ballot for the
parcel tax would be the best source of information.
Commissioner Schwartz asked about basement dewatering. The water went to the storm drain.
She asked whether the storm drain parcel tax was linked to the issue of basement dewatering.
Utilities Director Ed Shikada said the two issues were not linked.
Commissioner Danaher said the issue had been discussed at a prior meeting.
ACTION: Commissioner Schwartz moved, seconded by Commissioner Ballantine to recommend
that the City Council adopt the staff recommendation. The motion carried unanimously (6-0,
with Vice Chair Danaher and Commissioners Trumbull, Forssell, Danaher, Schwartz, Ballantine,
and Johnston voting yes and Commissioner Cook absent).
