Council Meeting: September 8, 1992 Santa Monica, California
TO: Mayor and City council
FROM: City staff
SUBJECT: Recommendation to Set Public Hearing on city's Urban
Water Management Plan for October 13, 1992
Introduction
This report recommends that the City council set a public hearing
for October 13, 1992, to receive public input regarding the
City's Urban Water Management Plan.
Background
In 1983 the State of California adopted the Urban Water
Management Planning Act which required every urban water supplier
serving more than 3,000 customers to prepare and adopt a one-time
five-year Urban Water Management Plan (UWMP) no later than
December 3l, 1985. On December 10, 1985, the city council held a
public hearing, received comments from the public, and adopted a
plan covering the years 1980-1985. The plan was subsequently
submitted to the state. The UWMP Act was to remain in effect
until January 1, 1991.
Amending legislation adopted by the state of California in 1990
required urban water suppliers to prepare and adopt an UWMP every
five years.
This report recommends that the city Council set a public hearing
for October 13, 1992, to receive comment on the 1985-l99Q Urban
Water Management Plan. A notice will be published in the Outlook

and the UWMP will be available for public review for thirty days
prior to the public hearing.
Discussion
The UWMP is intended to provide a level of water management
planning COIDmensurate with the number of customers served and the
volume of water supplied. The document is intended to provide
guidance in providing water utility service. The plan outlines
and reviews all aspects of the City'S past, current and future
water management practices including supply, demand,
administration, relevant city policies and conservation efforts.
Guidelines for preparing the 1985-1990 UWMP were prepared by both
the state of California Department of Water Resources and
Metropolitan Water District. The Department of Water Resources
also provided each agency with a copy of a custom software
package to determine the cost and benefit of each water
conservation activity. The software was used in the City's
report and the results are included as an appendix.
Included in the 1985-1990 plan is a residential and commercial
population growth projection which was used to forecast future
water demand. The growth projections were developed by City
staff and also were used in the city's Master Environmental
Assessment adopted by Council in February 1992.
During the preparation of the 1985-l990 UWMP, the City entered
into mandatory water conservation, adopted the Memorandum of
understanding Regarding Urban Water Conservation in California,
and began other important water operation and conservation

projects in ~991 which delayed the completion of the 1985-1990
plan. The activities which began in 1992 are included in the
plan as future activities and results ~"ill be included in the
1990-1995 Urban Water Management Plan.
The City will continue to improve the qual i ty and quantity of
existing water supply sources and manage demand through the
various aggressive water conservation activities to meet
projected residential and commercial water use.
Attached to the staff report is the Executive Summary of the City
of Santa Monica's 1985-1990 Urban Water Management Plan which
summarizes the contents of the plan. The Plan will be presented
to City Council prior to the October 13, 1992 pUblic hearing.
BUdget/Financial Impact
There is no budget or financial impact associated with this staff
report.
Recommendation
It is recommended that the city Council set a public hearing for
October 13, 1992, to receive public input regarding the 1985-1990
Urban Water Management Plan.
