COUNCIL AGENDA REPORT ITEM NUMBER:
FROM: William C. Statler, Director of Finance W�
Prepared by: Linda Asprion, Revenue Manager
SUBJECT: SEWER FUND RATE REVIEW
CAO RECOMMENDATION
Adopt a resolution setting sewer service charges for 1992-93 through 1994-95.
DISCUSSION
Overview
In June of 1990, the City Council approved a multi-year revenue program based on the
recommendations of Brown and Caldwell, consulting engineers, for the water reclamation
plant upgrade project. Under the adopted plan, sewer rates for single meter residential
(SMR) accounts would rise annually for four years by $2.00 per month, increasing from
$8.50 in 1989-90 to $16.50 by 1993-94. The primary purpose of these new revenues would
be to finance the construction and operation of major improvements in our treatment and
collection systems.
Since this revenue plan was originally prepared, we are now in a better position to fully
assess the capital and operating costs necessary to support these improvements. Based on
a detailed analysis of the sewer fund's financial requirements (Exhibit A), it is
recommended that SMR rates increase by an additional $ .50 in 1992-93 and $150 in
1993-94, resulting in a base rate of $18.50 per month in 1993-94 rather than the earlier
projection of $1650, an increase of 12%.
I
Summary of Changes in Key Assumptions
In preparing long-term revenue plans, it is necessary to develop a number of key
assumptions which are subject to change depending on their number and the level of
uncertainty associated with them. In preparing sewer rate projections, key assumptions
include:
■ Expenditure requirements for operations, capital outlay, and debt service
■ Customer service growth
■ Other revenues such as capital improvement charges and interest on investments
Exhibits A through C detail the rate requirements of the sewer fund through 1996-97
compared with original projections. As reflected in these exhibits, it is projected that sewer
fee revenues will be $560,000 less than required by 1993-94 (which is the 'base year" for
revenue requirements as operating and debt service costs associated with the treatment
and collection system improvements will be fully-developed by that time) under currently
scheduled rates.

COUNCIL AGENDA REPORT
A detailed summary of the changes in key assumptions that account for this shortfall is
provided in Exhibit C. As reflected in this summary, no one factor is responsible for this
shortfall, but rather, it is due to a combination of variances in several key assumption areas
for both revenues and expenditures. Major factors include:
■ Estimated revenues for 1993-94 under currently scheduled rates are 5% ($231,000)
less than projected by Brown and Caldwell. Staff believes that the primary factor
contributing to this shortfall is reduced effluent from non-residential customers due
to water conservation.
■ Projected revenues from interest earnings are lower than estimated by Brown &
Caldwell by $44,000.
■ The water reclamation program is estimated to cost $86,500 during 1993-94. Brown
and Caldwell did not include any costs for this program in their projections as the
program was developed after the completion of their report.
■ The pretreatment program is projected to have a net cost of $92,000 by 1993-94. It
was originally projected that this program would be fully-funded by user fees.
■ Ongoing capital maintenance requirements are $87,000 greater than projected by
Brown & Caldwell.
The revised projections include three key assumptions that continue to reflect high levels
of uncertainty:
Capital Improvement Charges Brown & Caldwell's and the revised projection reflect
comparable capital improvement charge revenues by 1994-95 ($620,900 vs $629,900).
However, this is based on a 1% growth rate. As reflected in the revised projection, only
$20,800 from this source is projected for 1992-93 and only $314,900 for 1993-94.
Cal Poly Charges. Staff is currently negotiating with Cal Poly to increase their rates based
upon the percentage of costs attributable to them for sewer treatment and collection
compared to total system costs. It is anticipated that this increase will be stepped in over
a five year period beginning in 1992-93. - Thereafter, Cal Poly rates will increase
concurrently with other customers. We anticipate submitting a new agreement with Cal
Poly reflecting this approach for Council approval in August of 1992.
Debt Service Requirements. As reflected in Exhibit A, our current projections assume that
repayment of the state loan will begin in 1992-93 at a cost of $251,500 for the relief sewer
main project only, with debt service for treatment plant units 3 and 4 beginning in 1993-94.
However, there is some uncertainty under current state guidelines concerning when
repayment should begin: upon completion of construction or within one year after the first
loan draw down. We believe that loan repayment should begin after completion of
construction, and staff is currently negotiating with the State to ensure that this repayment
schedule is followed. If the State requires payment within one year after the first loan draw
down, debt service costs for 1992-93 could increase by as much as $1.3 million; however,
there would be no impact on subsequent year debt service payments.

A COUNCIL AGENDA REPORT
FISCAL IMPACT
Compared with existing scheduled rate increases, the recommended rate structure would
increase monthly single meter residential (SMR) rates by an additional $ .50 in 1992-93 and
$1.50 in 1993-94, summarized as follows:
1992-93 1993-94
Currently Scheduled SMR Rate $14.50 $16.50
Recommended SMR Rate 15.00 18.50
For multi-family residential accounts, the rate structure is based on the concept of SMR
equivalencies using population per household ratios from the 1990 census:
1992-93
Monthly
Equivalency Rate
SMR Accounts 1.0 $15.00
Multi-Family Percent 0.8 12.00
Mobile Home Percent 0.6 9.00
For non-residential accounts, rates are adjusted on a percentage basis consistent with the
rate increase for SMR accounts.
After 1993-94, a modest rate increase of 5% is projected and is reflected in the
recommended rates for 1994-95.

1. The core of the sewer system's operating costs — treatment and collection — are very
close to the original projections,varying by only 2%.
2. The variance in A&E costs is primarily due to a change in the allocation of these costs
between sewer and water. When the projections were originally prepared, only 10% of
Utilities administrative and engineering costs were allocated to the Sewer Fund, with the
remaining 90% allocated to the Water and Whale Rock Funds. The sewer allocation has
been changed to 40% (with a commensurate reduction to the Water Fund)which better
reflects the allocation of the administrative workload between these two Divisions.
3. The pretreatment program was expected to be fully funded through industrial user fees; the
water reclamation program was implemented after the original projections were prepared.
4. Current projections for capital maintenance requirements are higher than original estimates.
5. Current revenue projections from the $16.50 rate are 5% less than the original estimates.
6. Revenues from this source are conceptually similar to the original estimates; howvever,
we are projecting revenues at a 1/2 percent growth rate rather than 1% for 1993-94.
Beginning in 1994-95, the 1%growth factor is used.
