AMES, IOWA MARCH 29, 2005
WATER & SEWER RATE WORKSHOP
The Ames City Council met in special session at 5:00 p.m. on the 29th day of March, 2005, in
Conference Room 235 of the City Hall, 515 Clark Avenue, pursuant to law with Mayor Tedesco
presiding and the following Council members present: Cross, Mahayni, Vegge, and Wirth. Council
Member Goodman arrived at 5:15 p.m. Council Member Goodhue was absent.
City Manager Steve Schainker explained that this Workshop would serve to inform the City Council
about different rate structures in an attempt to assist them in making a decision on how to fund an
approximate 10% increase that will be needed by July 1, 2005.
Water and Pollution Control Director Tom Neumann summarized the guidance given to staff since
1992 pertaining to water and sewer rate adjustments. He stated that sewer rates had not been
increased since 1995, and water rates had not been increased since 2000. Mr. Neumann explained
the steps taken by staff to determine rates, i.e., forecast of customers, volumetric sales, and revenues;
forecast of expenditures and determination of revenue needs; and, equitable allocation of the revenue
requirements to customer classes. Mr. Neumann advised that Ames currently charges a flat rate to
the different classes of customers (residential, commercial, and industrial). He pointed out that not
all customers consume service in the same manner or require the same facilities to be served.
The City was informed that cost classification was determined by dividing all costs among average
capacity (commodity), peak capacity (capacity), number of customers, and public fire protection
(water only). Mr. Neumann advised that many municipal utilities have different rate arrangements
for metered customers and contract customers. The basis for the differential is based on cost of
service, wholesale vs. retail, and inside/outside city limits. There are options for designing the rates:
fixed vs. variable charges or customer/commodity rates could be adjusted so that the end result of
revenue would be the same, e.g., a base rate plus a certain amount per 100 cubic feet of water
consumed. According to Mr. Neumann, last year, the City had approximately 100 customers/month
who did not use any water (were not at their residences); however, their meters still needed to be
read each month. He said that without a minimum rate, expenses would be incurred without any
revenue being generated.
Mr. Neumann described the financial policies for “minimum” reserve levels: operating reserve,
capital reserve, emergency reserve, and bond reserve. He reviewed the types of rate designs and
gave the positive and negative aspects of each. According to Mr. Neumann, June thru September
is the time of year when Ames incurs the highest demand for water; that is also the time when
overhead is the highest due to the cost of electricity being higher. It was stated that Ames has never
adopted a seasonal rate.
The Council was advised that water and sewer rate surveys have been conducted every two years
from Iowa cities over 10,000 population. Eighteen (18) cities assess a minimum bill with an
allowance, and 17 cities charge a service charge without an allowance. Mr. Neumann stated that
Ames has a median usage of approximately 550 cubic feet/customer. Eighty-five percent (85%) of
Ames’ customers use less than 1,000 cf/month. It was pointed out that 31 of the 35 cities surveyed
have a flat-rate structure; four cities have other rate structures, such as minimum bills with either
declining or inclining blocks. Ames assesses a minimum bill of $5.50/month with no allowance.
John Dunn, Assistant Director of Water and Pollution Control, reviewed data for Ames and fund
projections. Seventy-nine percent (79%) of the sewer fund projected revenues in 2004/05 came
from metered sales. According to Mr. Dunn, the growth rate in customer accounts is more than five
times the growth rate in billed volume. Assistant City Manager Bob Kindred explained that that was
an outgrowth of the apartment-to-condominium conversions. Mr. Dunn briefly explained the
2004/05 Sewer Fund projected expenses and Sewer Fund balances for years 2001/02 thru 2009/10.
He described several options for sewer rate adjustments. Still unknown are the requirements for
WPC Plant renovations/expansion that may be imposed on the City after receipt of the NPDES
permit.
Mr. Dunn advised that the current sewer revenue (FY 2003/04) is generated from assessing a
minimum bill of $5.50/month and $1.41/100 cf. With a ten percent increase, $340,000 in additional
funds would be generated. He then reviewed estimates for cost of service based on average
capacity, peak capacity, and the number of customers.
Potential rate structures were explained, as follows:
1. Raise minimum bill from $5.50 to $7.10/month and keep unit rate at $1.41/100 cf
2. Keep minimum bill at $5.50/month and increase unit rate from $1.41/100 cf to $1.61/100 cf
3. Allow cost of service to determine allocation, which would raise the minimum bill to
$7.35/month and decrease the unit rate to $1.38/100 cf
Comparisons of Alternatives 1 through 3 had been made and were explained by Mr. Dunn. Finance
Director Duane Pitcher described the overall impacts on utility bills for each of the three options.
Mr. Dunn said that it would also be possible to raise the minimum bill by ten percent (10%) and
increase the unit rate by ten percent (10%) to yield the desired increase in revenue. Staff did not
include this option in the comparison of alternatives, but could get information on this option to the
City Council if they so desired.
Mr. Dunn explained that they were requesting guidance from the City Council in establishing rates
that would generate an additional ten percent (10%) increase in revenue. Staff would then prepare
an ordinance and present it to the Mayor and Council. According to Mr. Dunn, Option 3 would most
closely meet the criterion that the minimum bill be set to closely recover actual costs.
Mr. Schainker suggested that the City Council members review the prior guidance that they had
given staff to ascertain if they still agreed with that direction.
Moved by Mahayni, seconded by Goodman, to reaffirm the Council guidance that was given since
1992.
Vote on Motion: 5-0. Motion declared carried unanimously.
Mr. Schainker informed the City Council that a decision on the specific rate structure needed to be
made at their next meeting.
Moved by Cross, seconded by Mahayni, to direct staff to present an alternative rate increase that
would allow for a ten percent increase in the minimum bill and a ten percent (10%) increase in the
unit rate.
Vote on Motion: 5-0. Motion declared carried unanimously.
COMMENTS: Moved by Wirth, seconded by Goodman, to place the issue of the Octagon billing
on the next agenda.
Vote on Motion: 5-0. Motion declared carried unanimously.
ADJOURNMENT: 7:12 p.m.
