Summary Title: FY 2017 Wastewater Financial Plan and Rate Proposals
Title: Utilities Advisory Committee Recommendation that the City Council
Adopt: (1) a Resolution Approving the Fiscal Year 2017 Wastewater Collection
Utility Financial Plan; and (2) a Resolution Increasing Wastewater Collection
Rates by Amending Rate Schedules S-1 (Residential Wastewater Collection
and Disposal), S-2 (Commercial Wastewater Collection and Disposal), S-6
(Restaurant Wastewater Collection and Disposal) and S-7 (Commercial
Wastewater Collection and Disposal – Industrial Discharger)
From: City Manager
Lead Department: Utilities
Recommendation
Staff and the Utilities Advisory Commission (UAC) recommend that the Finance Committee
recommend that the City Council:
1. Adopt a resolution (Attachment A) approving the fiscal year (FY) 2017 Wastewater
Collection Financial Plan (Attachment B); and
2. Adopt a resolution (Attachment C) increasing wastewater rates by amending Rate
Schedules S-1 (Residential Wastewater Collection and Disposal), S-2 (Commercial
Wastewater Collection and Disposal), S-6 (Restaurant Wastewater Collection and
Disposal) and S-7 (Commercial Wastewater Collection and Disposal – Industrial
Discharger) (Attachment D).
Executive Summary
The FY 2017 Wastewater Collection Utility Financial Plan includes projections of the utility’s
costs and revenues through FY 2026. Expenses have been higher than revenues for several
years, depleting reserves. In addition, costs are projected to rise substantially for the next
several years due primarily to increasing treatment costs. As a result, staff recommends a 9%
wastewater rate increase in FY 2017 and forecasts the need for rate increases ranging from 6%
to 10% through FY 2021. Rates for FY 2022 and beyond are projected to increase by 4%
annually.
City of Palo Alto Page 2
The UAC reviewed the FY 2017 Wastewater Collection Financial Plan and proposed rates at its
meeting on March 2, 2016 and unanimously recommended that Council approve staff’s
recommendations.
Background
Every year staff presents 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, both
retrospective and prospective, and are intended to be a reference for UAC, Finance Committee
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 financial
reserves for each utility and the management practices for those reserves.
The Finance Committee reviewed preliminary financial forecasts and rate projections for the
four Utilities funds at its March 1, 2016 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 projecting revenues and retail rates adequate to
recover these costs. The recommended rate adjustments 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 2016
1. Increase to $3.95 million the Transfer from the Rate Stabilization Reserve to the
Operations Reserve ($2 million was proposed in the FY2016 Financial Plan).
Proposed Actions for FY 2017
1. Transfer the remaining $394,000 from the Rate Stabilization Reserve to the Operations
Reserve.
These proposed actions are described in more detail in the FY 2017 Wastewater Collection
Financial Plan (Attachment B). These transfers will enable staff to maintain adequate
Operations Reserve levels while spreading the required rate increases for the wastewater
collection utility over several years.
Staff proposes to increase wastewater rates, as shown in Table 1 below, effective July 1, 2016.
The adjustments will increase the system average rate by roughly 9%. These rate changes are
included in the amended rate schedules (Attachment D).

FY 2017 Financial Plan’s Projected Rate Adjustments for the Next Five Fiscal Years
Table 3 shows the projected rate adjustments included in the Wastewater Collection Utility
Financial Plans and their impact on a residential wastewater bill.

Wastewater Utility 9% 10% 9% 7% 6%
Estimated Bill Impact for
Residential Customers ($/mo) $2.88 $3.48 $3.45 $2.92 $2.68
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 6% to 7% per year as the Regional Water Quality Control Plant makes several facility
City of Palo Alto Page 4
upgrades, as well as capital improvement costs for the wastewater collection system.
Operating and CIP costs are projected to rise roughly 2%-4% annually.
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. Staff plans to perform an
updated master plan for the wastewater collection system, and expects better information
about future main replacement costs when that plan is completed. Staff does not anticipate
this study to commence until sometime in 2016.
Wastewater Bill Comparison with Surrounding Cities
The annual sewer bill for a Palo Alto resident is $383 under current rates, 32% lower than the
average neighboring community. Table 4 shows the monthly sewer bills for residential
customers compared to what they would be in surrounding communities.

If the proposed wastewater rate change is adopted by Council, and assuming other agencies do
not change their sewer rates, Palo Alto would be 26% lower than the average neighboring
community. Staff has no information at this time as to whether or when the surrounding
communities are planning wastewater rate changes.
Changes from Prior Financial Forecasts
For the last several years, staff has projected wastewater rate increases for FY 2017 through FY
2019. Table 5 compares current long-term rate projections to those projected in the last two
year’s Financial Plans. As shown, the FY 2017 rate projections are the same as projected last
year. In the FY 2015 Financial Plan, the rate increase projections were lower than current
projections, but the FY 2017 projections reflect current information available regarding the cost
of capital improvements at the Regional Water Quality Control Plant.

Commission Review and Recommendation
The UAC reviewed the staff proposal at its March 1, 2016 meeting. When the UAC reviewed the
preliminary financial forecasts at its February 3, 2016 meeting, the UAC requested a more in
depth discussion of treatment costs as these are a major cost driver in the wastewater
collection utility. Jamie Allen, Manager of the Regional Water Quality Control Plant, described
the components of the treatment plant costs that are passed on the plant partners, including
Palo Alto. He explained that treatment plan operations costs are expected to grow at the same
rate they have for the last 5 years—about 5.5% per year—and that CIP costs grow at the rate of
inflation, about 2.6% per year. Debt service for major CIP projects is for planned plant upgrades
and is expected to increase from about $500,000 per year to $2 million per year in FY 2019
when the dewatering and sludge haul-off facility will be built allowing the destruction of the
incinerator.
Much discussion centered on the fact that Wastewater Collection Utility expenses were
abnormally low for FY 2014 (due to a hiatus in new funding for CIP expenses to allow staff to
catch up with CIP projects in process) and FY 2015 (due to a one-time change in accounting for
allocated charges). Staff explained that despite costs increasing at about 4.5% per year from FY
2016 to FY 2021, rate increases of 9%, 10%, 9%, 7% and 6% were required for each of these
years. Staff provided a detailed discussion of the cost drivers, reserve levels, and actual
revenues and expenses over the last five years, demonstrating hat, excluding the two
anomalous years of FY 2014 and FY 2015, costs have risen over time and rate increases have
been able to be deferred while financial reserves were drawn down to cover the difference
between revenues and expenses. However, at this point, rates must rise so that revenues begin
to catch up with projected expenses. The UAC noted that the public has been largely insulated
from the increasing costs as reserves have cushioned the impact.
The UAC voted to recommend that Council adopt resolutions to approve the proposed
Wastewater Collection Financial Plan and to increase wastewater rates by amending Rate
Schedules S-1, S-2, S-6 and S-7 as proposed. The vote was unanimous (5-0) with Chair Foster,
Commissioners Ballantine, Danaher, Eglash, and Schwartz voting yes and Vice Chair Cook and
Commissioner Hall absent. The draft excerpted minutes from the UAC’s March 2, 2016 meeting
are provided as Attachment E.
Timeline
Assuming the Finance Committee supports the proposed rate adjustments, notification of the
potential rate increases will be sent to customers as required by Article XIIID of the State
Constitution (added by Proposition 218). The proposed Financial Plans and amended rate
schedules will be considered by the City Council with the FY 2017 budget, at which time the
public hearing required by Article XIIID of the State Constitution will be held. All residents and
other interested persons may submit written or oral testimony at the hearing, and may also
submit written protests to any or all of the proposed rate increases. Council may adopt the
proposed rates unless written protests are filed by a majority of the affected customers.
City of Palo Alto Page 6
Resource Impact
Normal year revenues for the Wastewater Collection Utility are projected to increase by
roughly 9% ($1.45 million) in FY 2017 as a result of the proposed rate increases. See the FY 2017
Wastewater Collection Utility Financial Plan (Attachment B) for a more comprehensive
overview of projected cost and revenue changes for the next ten years.
Policy Implications
The proposed water rate adjustments are consistent with Council-adopted Reserve
Management Practices that are part of the Financial Plans and are developed using a cost of
service study and methodology that is consistent with the cost of service requirements of
Proposition 218.
Environmental Review
The Finance Committee’s review and recommendation to Council on the proposed FY 2017
Wastewater Collection Financial Plan and rate adjustments do not meet the definition of a
project, pursuant to Section 21065 of the California Environmental Quality Act, thus no
environmental review is required.

Resolution No. _________
Resolution of the Council of the City of Palo Alto Approving the
FY 2016 Wastewater 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 2017 Wastewater Utility Financial
Plan.
SECTION 2. The Council hereby approves the transfer of $3.95 million in FY 2016 from
the Rate Stabilization Reserve to the Operations Reserve, as described in the FY 2017
Wastewater Utility Financial Plan approved via this resolution.

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. It 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 5% per year
from fiscal year (FY) 2016 to FY 2026. The primary driver is wastewater treatment costs, which
are projected to rise by 7% in FY 2017 and 6% per year thereafter, with other costs rising at
roughly 3% to 4% per year. The costs for the Wastewater Collection Utility are shown in Table 1
below.

Expenses continue to be higher than revenues, and the Rate Stabilization Reserve has been
drawn down in lieu of having larger rate increases. To ensure that revenues cover these 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. Note that the rate
increase for FY 2017 is the same as projected in the FY 2016 Financial Plan.

The FY 2016 Financial Plan projected that reserves would fall nearly to the minimum reserve
levels. However, as costs are increasing faster than projected last year, higher rate increases are
required to keep pace.
The Wastewater Collection Utility’s Rate Stabilization Reserve is being used to spread the
projected cost increases over several years. The FY 2016 Financial Plan proposed a $2 million
transfer from the Rate Stabilization Reserve, but staff recommends increasing this to $3.95
million. This Financial Plan projects that the Rate Stabilization Reserve will be exhausted by FY
2017.

SECTION 2B: SUMMARY OF PROPOSED ACTIONS
Staff proposes the following actions for the Wastewater Collection Utility in FY 2016:
1. Transfer $3.95 million from the Rate Stabilization Reserve to the Operations Reserve.
See Section 3D: Proposed Reserve Transfers for more details.
Staff proposes the following actions for the Wastewater Collection Utility in FY 2017:
1. Increase the Wastewater Collection rates as shown in Section 3B: Current and Proposed
Rates. The changes are projected to increase average system revenues by 9% effective
July 1, 2016.
2. Transfer $342,000 from the Rate Stabilization Reserve to the Operations Reserve. See
Section 3D: Proposed Reserve Transfers for more details.
SECTION 3: DETAIL OF FY 2017 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 FINANCIAL PLAN
F e b r u a r y 2 0 1 6 6 | P a g e
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 2 to
3 years, 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.
SECTION 3B: CURRENT AND PROPOSED RATES
The current rates were adopted July 1, 2015, when the City increased sewer rates by 9%.
CPAU’s sewer rates for commercial customers are based on the previous winter’s water use.
This closely approximates non-irrigation water consumption, which represents actual sewer use.
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 (January through March). 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.
Table 4, below, summarizes the current and proposed rates for all customer classes.
Comparisons with neighboring communities are discussed in Section 4F: Competitiveness.

SECTION 3D: PROPOSED RESERVE TRANSFERS
In the FY 2016 Financial Plan, several transfers between reserves were approved. Funds related
to CIP’s in the Reappropriations Reserve were transferred to the CIP reserve, to comply with
updated accounting practices. Staff also proposed a $2 million transfer from the Rate
Stabilization Reserve to the Operations Reserve.
In this FY 2017 Financial Plan, staff recommends an additional $1.95 million transfer from the
Rate Stabilization Reserve in FY 2016. This will leave a small amount, $342,000, to transfer in FY
2017, which will result in a zero balance in the Rate Stabilization Reserve at the end of FY 2017.
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

through 2-2

F e b r u a r y 2 0 1 6 8 | P a g e
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 study
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 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 37% 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
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 2015, treatment costs represented nearly half of the Wastewater Collection Utility’s costs
(53%), followed by Operations (25%) and Capital costs (22%). These expenditures are shown in
Figure 1. The utility’s revenue in FY 2015, shown in Figure 2, came primarily from sewer charges
(86%), with the remainder coming mainly from capacity and connection fees and other sources
(14%).

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
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 $383 under
current rates, 32% lower than the average neighboring community. Palo Alto has the third
lowest bill of the group.

If the proposed rate change discussed in Section 3B: Current and Proposed Rates is adopted by
Council, and assuming other agencies do not change their sewer rates, Palo Alto would be 26%
lower than the average neighboring community and retain the third lowest bill.
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.

SECTION 5: UTILITY FINANCIAL PROJECTIONS
SECTION 5A: FY 2011 TO FY 2015 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 2026. For FY 2011 through FY 2015, Operations costs
grew at about the pace of inflation, at around 2% per year. Capital Investment expenses
actually saw a slight contraction over this period, but this was partially due to backlogged
projects necessitating a short term lowering of CIP budgets. Treatment costs during this time
rose by 4% annually on average.
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
F e b r u a r y 2 0 1 6 12 | P a g e
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 2015 and Projections through FY 2026
SECTION 5B: FY 2015 RESULTS
Forecast sources of funds for FY 2015 were higher than projected by $137,000, but expenses
related to Administration and Customer Service activities came in well below expected budget.
Total FY 2015 expenses were $16.15 million compared to projections of $18.64 million in the FY
2016 Financial Plan. Table 8 summarizes the variances from forecast.

SECTION 5C: FY 2016 PROJECTIONS
There are no notable changes from the FY 2016 budget identified at this time.
SECTION 5D: FY 2017 – FY 2026 PROJECTIONS
Staff has prepared a forecast of costs and revenues through FY 2026. 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 4.4% per year on
average for FY 2016 through FY 2026. The majority of this increase is borne by 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 6.3% 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. While some relief was experienced during times of lower
CIP expenditures, this trend of under-collection continues into the future, resulting in a rapid
reduction of reserves. A path of 9% and 10% 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 10% increase in FY 2018.

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.

F e b r u a r y 2 0 1 6 15 | P a g e
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 2021. 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 2016 meeting, the UAC suggested that staff prepare two alternate scenarios for
rate increases. The first (“Target”) scenario keeps the Operations Reserve at or near the Target
level during the forecast period. The second (“Minimum”) scenario tries to mitigate rate
increases and get as near to the minimum reserve level as possible for five years before moving
to Target level. Rate trajectories for both alternate scenarios as well as the proposed rate
adjustments are shown in Table 10 below.
Staff also modeled a scenario with no wastewater rate increase in FY 2017. This scenario
decreases the Operations Reserve to the Risk Assessment value, and requires a 25% in FY 2018
to keep reserves at that value for one more year, before net revenue growth starts.

Minimum 5% 19% 4% 4% 6% 6% 6% 6% 5% 4%
The Target scenario, represented in Figure 6 below, requires a 16% rate increase (larger than
the proposed 9% increase) in FY 2017, but reduces the rate increase slightly in FY 2018. The
Minimum scenario, represented in Figure 7 below, allows a lower rate increase in FY 2017, but
requires a significant rate increase (19%) in FY 2018.
Staff recommends a 9% wastewater rate increase in FY 2017 to smooth the rate increases over
the next two years while keeping the Wastewater Collection Operations Reserve at healthy
levels.

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.
Due to the ongoing drought and reduced wastewater flows to the plant, concentrations of
chemicals and solids have increased. The amount of chemicals needed to counteract and treat
this more concentrated wastewater increases and the cost of those chemicals has gone up in
recent years. Therefore, FY 2017 treatment costs are projected to increase by 7%, while over
the forecast horizon in general treatment costs are expected to rise by 6% per year. The longer
term cost increases are primarily due to increased CIP spending by the RWQCP.
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. Two of Palo Alto’s
comparison cities, Mountain View and Los Altos, are partners in the RWQCP and will see similar
increases, but other comparison agencies may not.
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
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
F e b r u a r y 2 0 1 6 19 | P a g e
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
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
WASTEWATER COLLECTION UTILITY FINANCIAL PLAN
F e b r u a r y 2 0 1 6 20 | P a g e
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.
Since the last master plan study was updated over a decade ago, and due to these escalating
costs, staff is considering a new wastewater collection system master plan study, tentatively
planned for 2016, to evaluate the current state of the sewer system and determine the optimal
rate of main replacement in future years. The process may reveal a need for a higher or lower
replacement, or possibly target areas for more urgent focus. In the case that prices remain high
and the updated plan shows a need for similar rates of replacement that CPAU had previously
planned, CIP costs will rise.
Customer Connections costs are projected to increase steadily by around 3% each year through
the end of the forecast period. Ongoing projects are seeing a temporary surge in FY 2016 but
are expected to drop by $200,000 in FY 2017, then resume a path of cost increases similar to
Customer Connections. 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 11 for the 5-year financial forecast period.
Table 11: Projected CIP Spending
Aside from Customer Connections, the CIP plan for FY 2017 to FY 2021 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 12 below.

1999 Utility Revenue Bonds, Series A 128 128 128 128 128 128
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 13, 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.

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.
8 Available Reserves as defined in the 1999 Utility Revenue Bonds included reserves for the Water, Wastewater

F e b r u a r y 2 0 1 6 22 | P a g e
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, operations and infrastructure, 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 publications, newspaper inserts, social media and email blasts.
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 first when there is 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 blasts and social
media. While print materials and website pages feature prominently, CPAU is increasing the
outreach emphasis on use of direct mail, social media and digital advertising including 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
F e b r u a r y 2 0 1 6 27 | P a g e
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
F e b r u a r y 2 0 1 6 28 | P a g e
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.

EXCERPTED DRAFT MINUTES OF THE MARCH 2, 2016
UTILITIES ADVISORY COMMISSION MEETING
ITEM 1: ACTION: Staff Recommendation that the Utilities Advisory Commission Recommend
that the City Action Council Adopt: (1) a Resolution Approving the Fiscal Year 2017 Wastewater
Collection Financial Plan; and (2) a Resolution Increasing Wastewater Rates by Amending Rate
Schedules S-1 (Residential Wastewater Collection and Disposal), S-2 (Commercial Wastewater
Collection and Disposal), S-6 (Restaurant Wastewater Collection and Disposal) and S-7
(Commercial Wastewater Collection and Disposal – Industrial Discharger)
Acting Rates Manager Eric Keniston provided a summary of the written report. He said that the
forecast of costs and rate changes has not changed from what the UAC saw last month when it
reviewed the preliminary financial projections. He said that the primary driver for the 9% rate
increase requested as well as the rate increases projected for the next several years is that the
costs of wastewater treatment are rising quickly. He noted that the Rate Stabilization Reserve
would be exhausted by the end of fiscal year (FY 2016 and that the Operations Reserve is being
drawn down as well. He said that the long-term rate projections assumed continuing increases
in treatment costs as well as operational costs.
Keniston noted that the 9% rate increase proposed is exactly what was projected in last year’s
Financial Plan. He noted that the rate trajectory in this year’s Financial Plan result in the
Operations Reserve going down to the minimum level in FY 2018 and FY 2019 before increasing
to the target level by FY 2022. He said that the 9% increase is the same for all customer groups
and that the increase for residential customers is $2.88 per month.
Keniston said that at its meeting last month, the UAC asked for scenarios showing the
Operations Reserve held to the minimum level and at the target level. He showed the in the
minimum reserve scenario, the FY 2017 rate increase could be held to 5% instead of 9%, but
that the rate increase for FY 2018 would be 19%. For the target reserve scenario, the FY 2017
rate increase would have to be 16% for FY 2017, following by a 9% increase in FY 2018 with
somewhat lower rate increases in the following years. After developing these alternate
scenarios, staff did not change its recommendation for a 9% rate increase for FY 2017.
Commissioner Danaher, noting that the reserve minimum is only about $2 million, asked what
would be done if the revenues were not sufficient and more money was needed. Keniston said
that a rate increase would be pursued if that ever arose. Such a mid-year rate increase would
need to go through the normal review process starting with the UAC, then consideration by the
ATTACHMENT E
Finance Committee—and the Proposition 218 45-day noticing process—with final decision by
the Council. Commissioner Ballantine asked if there is always enough notice of what its needs
are going to be. Keniston noted that in the Wastewater Collection Utility, the expense profile is
fairly flat and known ahead of the year and there shouldn’t be a surprise need for extra money.
Commissioner Ballantine asked if revenues could fall due to drought due to lowered water
usage. Keniston said that rates for this fund are generally independent of water usage with
only the commercial wastewater collection customers having revenues depend on relatively
steady wintertime water usage. Residential revenues are the majority of the fund’s revenues
and are based on a flat monthly charge so there is no variability due to changes in water usage.
Commissioner Danaher asked, if usage falls, do costs go down. Keniston responded that the
costs are fixed and revenues are also mostly fixed in the Wastewater Collection Utility and,
therefore, not dependent on the flow rate. Keniston said that the residential rates have no
element that is based on water flows.
Commissioner Eglash noted that the real cause for the dramatic rate increase seems to be the
wastewater treatment costs. He asked why those costs rose so much from FY 2014 to FY 2015
and from FY 2015 to FY 2016.
Keniston introduced Jamie Allen, Regional Water Quality Control Plant Manager, to describe
the components of the treatment plant costs that are passed on the plant partners, including
Palo Alto. Allen explained that there was an accounting change that lowered the costs for one
year in FY 2014 so that year’s costs are anomalous. He said that the majority of the wastewater
treatment costs are operations costs with two categories of capital improvement program (CIP)
costs—“minor”, or rate-funded CIP and major CIP debt service. Operations costs are expected
to grow at the same rate it has for the last 5 years—at about 5.5% per year and CIP costs are
discussed with the plant partners and minor CIP costs grow at about the rate of inflation, about
2.6% per year. Major CIP debt service is for planned plant upgrades.
Allen showed a breakdown of the FY 2017 wastewater treatment costs: 47% for salaries and
benefits for operators, engineers, chemists, etc.; 12% for allocated charges for services
provided by the City such as HR, attorney, IT, finance, etc.; 9% for utilities expenses (electric,
gas, water); 11% for minor CIP projects; 7% for contract services; 3% for debt service for major
CIP projects; and 10% for general expense and supplies and materials.
Commissioner Eglash summarized this to say that minor CIP are only modestly growing, major
CIP expenses are growing from about $0.5 million per year to $2 million per year and that
operations expenses are growing by 5.5% per year, a modest and steady rate. He noted that the
charts showed that expenses were lower than revenues for FY 2014 and FY 2015, which
replenished the reserves. In FY 2016, costs were above revenues. He said that rate increases on
the order of 9% per year for the forecast horizon period don’t make sense and are impossible to
explain to the public when treatment costs are only rising 5.5% per year. Keniston said that CIP
expenditures were lower for the wastewater collection (not for wastewater treatment) in FY
2014 and FY 2015, but that CIP costs are projected to increase over the forecast period.
Commissioner Eglash concluded that, based on the numbers, an increase in treatment cost is
not the real cause of the high rate increases forecast, but instead there was a period of time
when costs were rising, but no rate increases were put into place, which resulted in a drawing
down of reserves. Keniston said that reserves will be drawn down in FY 2016 through FY 2018
until revenues balance expenses. Commissioner Eglash agreed that reserves have been
depleted over time.
Commissioner Danaher asked for an explanation of the difference between wastewater
treatment costs and wastewater collection costs. Keniston said that the wastewater treatment
fund’s expenses are paid by the plant partners including Palo Alto and that those wastewater
treatment costs are an expense for the wastewater collection utility. Interim Utilities Director
Shikada said that the wastewater conveyance is a Utilities activity and that wastewater
treatment is a Public Works activity and that the combined costs are paid for by ratepayers.
Wastewater Collection Utility expenses include the treatment costs, which are a pass through
expense from the wastewater treatment plant.
Commissioner Schwartz noted that the wastewater collection operations costs increased
significantly from FY 2015 to FY 2016. Keniston said that this was due to a one-year accounting
anomaly. Assistant Director Jane Ratchye said that the three primary costs buckets for the
wastewater collection fund include: 1) operations costs for wastewater collection, which are
rising at 2-3% per year; 2) CIP costs for wastewater collection, which are rising at 2-3% per year;
and 3) wastewater treatment costs, which are rising at 5-6% per year. The treatment costs that
are passed through to the wastewater collection utility are the main driver for increasing
costs—and, therefore, rates.
Allen pointed out that his breakdown of the wastewater treatment expenses showed the costs
in terms of operations, minor CIP and major CIP debt service. He noted that there was a major
jump in major CIP debt service in FY 2019 when the dewatering facility would go on line.
Commissioner Eglash reiterated the difficulty in explaining that total wastewater collection
expenses are rising at 4-5% per year, but we are asking for rate increases of 9-10% per year
without driving the reserves below the minimum. He said that a better explanation must be
forthcoming or the projected expenses should be reduced.
Public Comment
Herb Borock said that wastewater treatment plant costs estimates for the future are increasing
dramatically, but that no explanation has been provided for the CIP plans at the treatment
plant. He said that Council has approved a plan to replace the incinerator with a dewatering
and load-out facility and that the current plan is to have an anaerobic digester at the plant. He
said that the cost for the anaerobic digester keep increasing dramatically. He said it’s unclear
what assumption is in the cost projections regarding what happens after the incinerator is
dismantled – will we keep using the haul out facility, or will something be built on site to handle
the sludge. Trying to predict future costs depends on the plan and how easy it would be for
Council to change direction. He said that the long-term facilities plan at treatment plant should
be reviewed again by Council since there are choices about what to do that have impacts on
greenhouse gas emissions. He also commented on the Proposition 218 noticing process saying
that the Council should support the rate proposals prior to staff issuing the Proposition 218
notices.
Commissioner Eglash said that in order to support the proposal, he would need a better
understanding of the revenues and expenses over the years. Ratchye pointed to page 24 of the
Wastewater Collection Financial Plan (Appendix A: Wastewater Collection Financial Forecast
Detail) that is attached to the UAC memo and reminded the UAC that the reserve structure was
changed in FY 2015 to lower the reserve amounts and that at the time of the change, there was
significant money in the reserves that was placed initially in the new Rate Stabilization Reserve,
which would normally have a zero balance. Over FY 2015 and FY 2016, all the funds in the Rate
Stabilization Reserve will be drawn down to zero. She said that reserves were being drawn
down in FY 2011, FY 2012, and FY 2013, then there were two anomalous lower cost years—in
FY 2014 when there was a one-year hiatus in new CIP budgeting and in FY 2015 when reduced
operations expenses due to an accounting anomaly—when reserves were somewhat
replenished. However, underlying those anomalies, costs were rising and revenues were not
keeping pace. As shown on page 24 of the plan, reserves will be drawn down again in FY 2016,
FY 2017 and FY 2018 before revenues catch up with expenses. She said that rate increases
need to be significant to get revenues to the levels that are needed to cover expenses.
Commissioner Eglash said that his understanding from that explanation is that we’ve allowed
revenues to fall below expenses during the last few years and we did that because costs were
increasing steadily and we chose not to increase rates. The reason we did not increase rates is
that reserves were available to draw on. In addition, there were two years with anomalously
low cost that somewhat replenished reserves, but we are now at the point when we must
increase revenues. He said that he can now see this on page 24 of the plan (line 20: into/(out
of) reserves), which shows that reserves were drawn down in FY 2011 through FY 2013, were
replenished in the anomalous years of FY 2014 and FY 2015, but that reserves will be drawn
down again in FY 2016, FY 2017 and FY 2018 before revenues cover expenses. He said that
reviewing line 18: (total uses of funds) shows that expenses increased slightly from FY 2012 to
FY 2013, but increased about $3.6 million from FY 2013 to FY 2016 ignoring the anomalous
years of FY 2014 and FY 2015. Then costs increase by about 5% from FY 2017 and onward. He
said that the costs increases have been hidden from customers. He said that even with adding
$4 million to reserves in FY 2014 and FY 2015, that a 9% increase in revenue is needed. He said
that it seems like with costs increasing at about 5% per year, we should be fine with 5% per
year rate increases. Ratchye pointed out that a one-time adjustment into reserves doesn’t help
much with ongoing cost increases whereas a 9% rate increase raises revenue to a new base
level upon with a subsequent 9-10% rate increase will increase revenues even more with the
power of compounding.
Commissioner Eglash said that he was beginning to understand the issue by examining the lines
on page 24 of the plan showing the “Total Sources of Funds” and the “Total Uses of Funds,”
which show that revenues have not been keeping up with expenses for years. Keniston says
that revenues have not kept up with expenses for a period beyond the years shown on the
chart on page 24 and was the case in FY 2009 and FY 2010 as well. Commissioner Eglash said
that we have been in a long period when rates provided insufficient revenues to cover normal
year expenses (ignoring FY 2014 and FY 2015). He asked how revenues could lag expenses for
up to 7 years. Ratchye said that the answer to that question is that reserves were high and that
the anomalous two years of lower expenses made calling for rate increases hard to justify. In
addition, the change to the reserve structure in FY 2015 lowered the amount of reserves that
were considered sufficient—and this is the case for all funds, not just the Wastewater
Collection Fund.
Commissioner Eglash said that the reserves were reduced when we realized that we had more
than we needed and we’ve been slowing consuming them over the years and that all customers
have been the beneficiaries for several years of holding the line on rates by using the financial
reserves. The day of reckoning has been delayed due to the two anomalous years of low
expenses. He said that with no rate increase, we would have a $3 million deficit and we don’t
have enough reserves to cover that and we need to get back to a place where income covers
expenses and staff’s proposal phases in rate increases so that we don’t get to that place until FY
2019.
Commissioner Schwartz agreed that the public has been insulated from the increasing costs so
now we need to raise rates to cover costs. This can be presented as saving the customers over
the last several years when rate increases were low.
Commissioner Eglash said that a chart comparing revenues to costs would show the years when
there was a deficit and costs were not covered by revenues and for how long this went on. It is
the same as if your salary was staying the same, but rent climbs and when you deplete your
savings, you have a problem and can’t afford the rent.
Chair Foster said that the Council made decisions in past to delay rate increases and now the
rates must increase. He said that he recalls that in the past several years, moderate rate
increases could have been proposed, but the case for them was somewhat borderline and that
there was value in a zero rate increase for the community knowing that, sooner or later, the
rates would have to increase. Ratchye agreed and recalled that these conversations occurred
every year; for example, last year, staff proposed a 3% gas rate increase followed by a 4%
increase the following year, but the feedback was that a 3% increase was so low that it’s not
worth it and would be better to have no rate increase and a 7% in the following year. Chair
Foster said that there is a desire to insulate customers from rate increases and that, even with a
delayed higher rate increase, the customers are not actually paying more over the whole
period.
Commissioner Ballantine noted that (on the chart on page 24) the allocated charges (line 12)
are anomalously low in FY 2015 and that for FY 2016 and forward, those costs are rising. He
said that the low cost in FY 2015 could be due to an operational cost saving that year that could
be found in future years, but the future forecasts do not include any cost savings that may
actually accrue.
Commissioner Eglash pointed out the reduced cost for FY 2014 could be repeated in the future,
but that the projections show costs only increasing, which may not reflect reality. Ratchye
pointed out that the reduced CIP costs in FY 2014 was a cause for consternation in the past as
the UAC and Council was concerned that it signaled a slowdown in infrastructure replacement.
However, it was only a pause in new funding for CIP to allow staff to catch up to CIP projects in
the queue. She also pointed out that the allocated cost line item referred to by Commissioner
Ballantine is not related to operational cost savings, but are the costs allocated from the
services provided by the City such as HR, City attorney, finance department, etc. and that the
reduced charges in FY 2015 were related to an accounting anomaly. Both these one-time cost
reductions are not related to finding efficiencies were found and that these efficiencies won’t
be found in the future.
Commissioner Eglash said that he was now adequately satisfied with the explanations for the
need for the rate increase and supports going forward with the staff recommendation.
ACTION:
Commissioner Danaher made a motion that the UAC recommend that the Council adopt
resolutions approving the FY 2017 Wastewater Collection Financial Plan and increasing
wastewater rates by amending Rate Schedules S-1 (Residential Wastewater Collection and
Disposal), S-2 (Commercial Wastewater Collection and Disposal), S-6 (Restaurant Wastewater
Collection and Disposal) and S-7 (Commercial Wastewater Collection and Disposal – Industrial
Discharger). Commissioner Schwartz seconded the motion. The motion carried unanimously
(5-0) with Chair Foster, Commissioners Ballantine, Danaher, Eglash, and Schwartz voting yes
and Vice Chair Cook and Commissioner Hall absent.
