SUBJECT: 1997 SEWER FUND RATE REVIEW
CAO RECOMMENDATION
1. Review and discuss the 1997 annual sewer fund report; and
2. Adopt a resolution increasing sewer service charges by-two and one-half percent (2.5%),
effective July 1, 1997; and by one and one-half percent(1.5%), effective July 1, 1998.
DISCUSSION
Overview
This report presents the 1997 review of the sewer fund and requests adoption of increases to the
sewer service charges by 2.5 percent, effective July 1, 1997; and 1.5 percent, effective July 1,
1998. This analysis shows that these modest rate increases will result in revenues matching
expenditures in 1998-99, and no rate increases are projected for 1999-00 and 2000-01. This is a
significant achievement, after a number of challenging years for the sewer fund. It represents the
Department's ongoing efforts to contain operating costs and to recommend prudent capital
expenditures to ensure infrastructure reliability and reduce emergency expenditures.
Within this analysis are two prior years of financial information, an update to projections for the
1996-97 year end, and a forecast for the next four years through 2000-01. In summary, this
analysis confirms the sewer fund meets the fiscal policies established by the City and can support
the recommended operating budgets and capital improvement plan contained in the preliminary
1997-99 Financial Plan.
Background
As Council recalls, the sewer fund has gone through nearly ten years of being hard hit to pay for
$35 million of infrastructure improvements to ensure the City complies with the State Regional
Water Quality Control Board's discharge requirements. This has resulted in a treatment process
that produces a high quality effluent that can be recycled and used as a new source of supply for
the City. It also resulted in fiscal challenges to the sewer fund that were met through systematic
rate increases and, finally, through the$3.049 million equity contribution from Cal Poly.
Council Agenda Report- 1997 Sewer Fund Rate Review
Page 2
While the equity contribution ensured fund stability, one key issue remains:. how to most
appropriately close the remaining small gap between expenditures and revenues.
If fund balance alone is used to meet expenses (with no rate increase), over$2 million of the fund
balance will be consumed over a four year period. Under this scenario, the modeling predicts that
revenues and expenditures will not meet until the year 2000. On the other hand, under the
recommended scenario (see Exhibits B.1, B.2 and B.3), rate adjustments cover ongoing operating
expenses; revenues meet expenses in 1998-99; and fund balance is used for one-time capital
expenses.
When is it appropriate to use fund balance to meet the deficit between revenue and
expenditures?
City policy has been that is it not appropriate to use fund balance as an ongoing strategy for
ensuring revenues meet expenditures. Rather, routine operating costs must meet revenue
projections. In line with this, city policy has been that it is appropriate to use fund balance to pay
for one-time capital expenses. Appropriate use of capital funding in this manner often results in
an ongoing reduction to operating costs.
What is the appropriate working capital level(`fund balance') in the sewer fund?
In this analysis fund balance exceeds the 20% of operating expense requirements. Using surplus
fund balance to reduce or eliminate projected rate increases is not recommended because
significant infrastructure costs may be identified in the Sewer Master Plan.
Being developed in conjunction with Airport Area Specific Plan, the Sewer Master Plan will
address capacity demand issues in the Edna-Islay, Tank Farm area and system improvements
necessary to meet full General Plan build-out projections. It will identify system deficiencies and
provide recommendations, cost estimates, and a phasing strategy for system improvements. The
Plan is expected to take up to two years to complete and should recommend a number of
improvements which are likely to be costly to implement.
Following the completion of the Sewer Master Plan, staff will return to Council with a thorough
discussion of appropriate levels of fund balance for the Sewer Fund and recommendations for
setting a revised fund balance policy, if necessary.
Rate Review Exhibits and Objectives
The proposed 1997-98 and 1998-99 sewer service charges are provided in Exhibit A. Financial
schedules providing detail for the sewer fund analysis are provided in Exhibits B.1 through B.3.
The rate review is to be conducted within the framework of the following 1988 Council approved
objectives:
a- a
Council Agenda Report- 1997 Sewer Fund Rate Review
Page 3
■ Comply with legal requirements
■ Ensure revenue adequacy to fully meet system operating and capital needs
■ Encourage conservation
■ Provide equity and fairness between classes of customers
■ Result in rate structures that are easy to understand by our customers and easy to
administer
■ Provide for ongoing review to facilitate rate stability
Rate Setting Methodology
In determining sewer revenue requirements and setting recommended rates, the following general
methodology is used:
Step 1: Determine Sewer Fund revenue requirements for:
■ Operations and maintenance
■ Capital improvements and replacements
■ Debt service obligations (existing and projected)
Step 2: Subtract from this amount "non-rate revenues" such as:
■ Interest earnings
■ Connection fees
■ Other service charges (lateral installations and abandonments, etc.)
Step 3: Identify sewer rate requirements:
■ Revenue needed to be generated from sewer rates is the difference between
sewer revenue requirements (Step 1) and "non-rate" revenues (Step 2).
Step 4. Determine new rates:
■ Model the rate base(consumption and customer account assumptions) against
the existing rate structure and rate requirements identified in Step 3.
Capital Improvement Plan
Capital improvements for the sewer system are a critical component of Utilities' expenditures.
The consequences of inadequate capital replacement of aging infrastructure can be catastrophic
failure, high cost emergency repair, loss of service and potential fines from regulatory agencies.
To ensure adequate capital replacement of infrastructure, staff has recommended and Council has
adopted a 2% replacement strategy. This is based on a goal of infrastructure replacement on a
50-year cycle, generally considered to be the useful life of most sewer infrastructure. Following
this strategy allows us to systematically attain our capital improvement goals, while avoiding
significant rate increases associated with system failure or"catch-up" CII'.
In the sewer system, this strategy translates into annual goals of$750,000 for pipeline
replacement (current requests are at the $650,000 level because $100,000 has been identified for
the Lateral Rehabilitation Program) and reclamation facility maintenance of$250,000 per year.
Vehicles are replaced as part of the sewer fund's CIP, on a schedule adopted in the Fleet
Management Policy.
�-3
Council Agenda Report- 1997 Sewer Fund Rate Review
Page 4
For 1997-98, staff is recommending a one-time increase to the target funding for the reclamation
facility. The preliminary sewer capital improvement plan(Exhibit B-3) identifies $707,800 for
structural improvements to the Water Reclamation Facility, including $360,000 for paving the
biosolids handling area. The recommended level of capital expenditure exceeds the target amount
by$457,000, and consistent with the previously discussed policy, staff is recommending that fund
balance be used to fund this important capital project in 1997-98.
Other projects included in the Sewer CIP are a proportionate share of projects originating in other
departments and $30,000 for an upgrade to the Hansen software used to maintain the collection
system.
Ongoing levels of recommended expenditures are under review and will be further refined in the
facility-specific CIP management plans which Utilities is developing. Aimed at ensuring sound
and adequate CIP planning and programs, these plans should avoid any one-time revenue
shortfalls associated with a piling up of Capital improvement projects in any one financial plan.
Summary of Key Assumptions
Based upon the assumptions in Exhibit B.2 and the factors discussed above, the financial position
projections indicate that sewer rates require an increase of 2.5% in 1997-98 and 1.5% in 1998-99.
The following is a summary of key assumptions for expenditures and revenues:
■ Operations and maintenance costs are based on the preliminary 1997-99 Financial Plan
with an inflation rate of 3%thereafter.
■ Sewer customer growth rate is projected at less than 1% until 2000-01.
■ Capital improvement charges (development impact fees) are estimated based on
inflationary and customer growth adjustments to the base year(1992-93)projection of
$583,200, which assumed annual growth of 1% in the City. These impact fees are
projected at $202,700 in 1997-98 and $349,800 in 1998-99.
■ Annual debt service payments of$2,135,900 are to repay the State Revolving Loan Funds
received by the City for the construction of the Unit 3 and 4 improvements to the Water
Reclamation Facility and collection system improvement("Relief Sewer Main").
FISCAL IMPACT
The proposed 2.5% rate increase will establish monthly sewer rates of$21.47 for single family
dwellings in July 1997. This is an increase of 52 cents over the 1996 single family monthly
charge. The proposed 1.5% rate increase will establish monthly sewer rates of$21.79 for single
family dwellings in July 1998. This is an increase of 32 cents over the recommended 1997 single
family monthly charge.
