CITY COUNCIL OF ARROYO GRANDE
SPECIAL STUDY SESSION
APRIL 12, 1988 6:30 P.M.
COUNCIL CHAMBERS, 215 E. BRANCH STREET
ARROYO GRANDE, CALIFORNIA
The City Council met in special study session with Mayor Howard Mankins
presiding. Also present were Council Members Dorace Johnson, Mark Millis,
Gene Moots and D. G. Porter.
Paul Karp, Director of Public Works, referred to his memo of April 5, 1988
regarding the City Water Master Plan Update. He said that update of data
and a review of current quality standards and production capabilities have been
condensed into a single report which recommends a capital improvement program
for the City's water system. About 3/4 million dollars in Safe Drinking Water
Bond monies is available. That money may be borrowed from the State over an
extended period of time at about 8 1/2 % interest.
Interim City Manager Chris Christiansen introduced Jim Garing of Garing,
Taylor & Associates who gave a presentation on Phase 1 Water System Study Update.
He explained that the first exhibit showed population trends. Today the population
is at about 13,720. The projection is for growth at about 3% per year. The ultimate
buildout is expected to be 20,000 as early as 1995 under some growth scenarios.
Water use today is about 190 gallons per person per day.
The City receives its domestic water from two sources which include Lopez,
2,290 acre feet, which is 50.5% and groundwater from Arroyo Grande Sub Basin wells
within the city. The current total available resource from the Lopez prOject
and Zone Three extractions is 3,492 acre feet per year. The City has the
physical ability to pump 5,217 acre feet per year but this capability should be
used only to meet peak instantaneous demand. He saic that the City had agreed in
past not to pump in excess of 1,202 acre feet of ground water in any year. The
purpose of the agreement among public agencies extracting drinking water from the
Arroyo Grande Basin was to preserve groundwater being extracted for agricultural uses
Not all of the water produced is sold. Some is lost to meter errors,
flushing hydrants, water in parks that don't have meters. The difference varies
up to 7% on an annualized basis
Starting at today's usa~e of water, and growing at 2 1/2 %, we will use up our
water just prior to 1995 or pI' or to 1991 if 9rowth rate is 5%, he said.
One recommendation is to look for another resource. The possibility of
developing an additional groundwater resource exists in the Oak Park/Rancho Grande
area. To meet peak demand a new shallow well in the Elm Street Park should produce
approximately 900 gallons per minute, he said.
Paul Karp, in his summary, reemphasized the availability of the 3/4 million
dollars for ensuring a continued reliable source of domestic water which meets
State standards for quality. The money is in addition to normal funding. This
study was done to project the City's needs so that a decision can be made before
May 1, 1988.
Mr. Christiansen explained that the repayment of the funds at 8~ percent
for 35 years would be $75,000.00 per year, and would add approx.lmately $14.00
per year or a little over $1.00 per month to the average customer.
Mayor Mankins thanked Jim Garing and Paul Karp for their reports and
advised the Council that a decision must be made by May 1, 1988.
The meetin~ was adjourned at 7:25 P.M. to the Regular Council Meeting at
7:30 P.M. Aprll 12, 1988.
