SUBJECT: 2010 URBAN WATER MANAGEMENT PLAN UPDATE
RECOMMENDATION
Adopt a resolution approving the 2010 update to the City of San Luis Obispo's Urban Water ,
Management Plan.
DISCUSSION
Background
The State of California Urban Water Management Planning Act (Act) requires every urban water
supplier providing water for municipal purposes to more than 3,000 customers, or supplying
more than 3,000 acre-feet of water annually, to prepare and adopt an Urban Water Management
Plan (Plan) every five years (years ending in -00 and -05). The City Council adopted the City's
first Plan in November 1994. Subsequent updates have been submitted to the state in 2000 and
2005. Because of the significant amendments made to the Act in late 2009, the state legislature
extended the filing deadline for the 2010 Plan to July 1, 2011.
Since the Act's passage, many changes have been made to the required content in the Plan. These
amendments are intended to encourage increased awareness of a water purveyor's responsibility
to effectively manage California's water resources. As a result, Urban Water Management Plans
in general have evolved to become the following:
1. Foundational documents and sources of information for Water Supply Assessments
(California Water Code Section 10613) and Written Verifications of Water Supply
(California Water Code Section 66473.7)
2. Long-range planning documents for water supply
3. Long-range planning documents for water use efficiency
4. Source data for the development of regional water plans
5. Source documents for cities and counties preparing their General Plans
6. A condition of eligibility for receipt of certain state loans and grant funds
The most significant changes in the 2010 Plan update are a comprehensive reorganization of the
sections to meet the requirements set forth under the Act, the elimination of the water policy
section, and the addition of the 2009 Water Conservation Act requirements (discussed later in
this report).
PH2-1
2010 Urban Water Management Plan Page 2
The City's guiding water policy document for water planning purposes is the Water and
Wastewater Management Element of the General Plan (WWME). In the past, the WWME was
fully incorporated into a water policies section of the Urban Water Management Plan. In the
2010 Plan update, the WWME is incorporated by reference. This allows a single policy
document to be updated if changes to water policy occur.
The specific purposes of the Plan are summarized as follows:
1. Document and assess current and future water use trends in the community
2. Describe the sources of water supply and the water system
3. Assess water supply reliability
4. Document the water demand management measures in place to balance supply and
demand
5. Act as a source document on the background and history of the water supply system
6. Demonstrate compliance with state law regarding water planning and water conservation
The Plan being presented to the City Council has been updated in accordance with all the
provisions of the Act (as amended).
Plan Organization
In order to present the material in a manner that best reflects the unique conditions within the
City of San Luis Obispo's water service area, the sections in the Plan are sequenced slightly
different than the guidance documents developed by the Department of Water Resources, The
Plan still meets the requirements set forth in the Act.
The Plan is organized into the following sections:
Section 1. Introduction
Section 2. Service Area and Water System Description
Section 3. Past, Current and Projected Water Demand
Section 4. Water Sources
Section 5. Recycled Water
Section 6. Water Supply Reliability
Section 7. Water Conservation
Section 8. Water Shortage Contingency Plan
Appendices
Section Summaries
The following information summarizes the content of each section of the Plan. A complete copy
of the Plan is located in the Council Reading File,
PH2-2

Section L Introduction
The introduction provides the framework for updating the plan, the City's coordination with
other agencies in preparing the Plan, and the process leading to adoption. It identifies the
responsible City staff for implementing the Plan.
Section 2. Service Area and Water System Description
The first part of this section provides a general description the City's service area including
climate, population, and demographics. This is followed by detailed explanation of the water
system including raw water transmission, water treatment (including treatment processes and
impacts of current and future regulations), groundwater resources, and a comprehensive
overview of the water distribution and meter reading operations.
Section 3. Past, Current and Projected Water Demand
Section 3 evaluates past water use trends in order to project future water demand in the
community including required elements such as water use projections for low income housing,
water losses through the water distribution system, and water supplied from the Nacimiento
Reservoir by the San Luis.Obispo County Flood Control and Water Conservation District.
The most important component of this section is the inclusion of the new state mandated water
use reduction requirements. The Water Conservation Bill of 2009 (SBx7-7) requires each urban
retail water supplier in California to develop urban water use targets to help meet the goal to
reduce the statewide average per capita daily water consumption by 20 percent by the year 2020
and an interim reduction goal by 2015. The legislation outlines four "target method" reduction
options that can be used by a water retailer to calculate the baseline and targets.
Using the guidance documents provided by the Department of Water Resources, Target Method
3, which uses a regional average for water use and creates a higher baseline, best aligns with the
investment the community has already made in water conservation. Using this target method
provides reasonable water use reduction Table 1- 2015 and 2020 Per. Capita Targets
goals for 2015 and 2020.
Table 1 shows the per capita targets the City Year Adjusted Per Capita Target
120 cd
must meet to be in compliance with the law. 2020 117 cd
Failure to meet the targets will result in the
City not being eligible for water or wastewater grants, State Revolving Fund loans, or other
assistance offered by the State Water Resources Control Board or the Department of Water
Resources. To put the 2015 and 2020 targets in context, the City's per capita rate for the year
2010 was 109 gallons per person per day.
Section 4. Water Resources
Section 4 provides a comprehensive overview of each of the City's water supply sources
including Salinas, Whale Rock, and Nacimiento Reservoirs, groundwater, and recycled water.
Background and historical information is also presented for each water supply source. It includes
brief discussions of water transfer and exchange opportunities, future water supply projects, and
the potential use of desalination as a water supply which are required sections per the Act.
PH2-3
2010 Urban Water Management Plan Page 4
Section S. Recycled Water
Extensive information about the City's wastewater collection and treatment operations, water
recycling system, and an explanation of current and potential uses of recycled water in.the future
is found in Section 5. It consolidates the information in a manner that it is easy to read and
understand.
Section 6. Water Supply Reliability
A narrative on each water source is provided in this section. The reliability of each supply to
provide water during single and multiple dry years is described. Much of the information and
data in the tables are required elements to include in the Plan. The resulting conclusion from this
data gathering exercise is that the City has highly reliable sources of water and policies in place
that ensure current and future residents and businesses have an adequate water supply.
Section 7. Water Conservation
Because of the City's affiliation with the California Urban Water Conservation Council (Urban
Council), the Act specifies that Urban Council members can submit their Best Management
Practices (BMPs) annual reports to comply with this portion of the law. Appendix V includes the
documentation of the City's ongoing water conservation program.
Section 8. Water Shortage Contingency Plan
The Water Shortage Contingency Plan remains relatively unchanged since the City Council
adopted it back in the year 2000. This plan was developed based on the experiences gained
during the City's water rationing program, which was in effect from 1989 through 1992. The
section was updated to reflect the required elements, mostly tables, in the Act.
Appendices
Appendices I through VII contain the supporting documentation for the various sections of the
Plan.
Environmental Determination
According to the Urban Water Management Act, Urban Water Management Plans are exempt
from the California Environmental Quality.Act. Chapter 4, section 10652 of the Urban Water
Management Planning Act states:
The California Environmental Quality Act (Division 13 (commencing with Section 21000) of the
Public Resources Code) does not apply to the preparation and adoption of Plans pursuant to this
part or to the implementation of actions taken pursuant to Section 10632 (Water Shortage
Contingency Plan). Nothing in this,part shall interpreted as exempting from the California
Environmental Quality Act any project that would significantly affect water supplies for fish and
wildlife, or any project for implementation of the plan, other than projects implementing Section
10632, or any project for expanded or additional water supplies.

Summary
The development and preparation of past updates of the Urban Water Management Plan played a
large role in the City's water supply planning, water operational program evaluation, and water
policy implementation. With a relatively secure and reliable water supply, which will meet the
current and future water demands of the community, the water supply evaluation and data
collection provision required by the Act are not as relevant to the City today as they were in the
past. The Plan documents the history of the City's water supply development and provides
detailed description of the water system. Most importantly, by adopting a compliant Plan, the
City will remain eligible for State Water Resources Control Board and Department of Water
Resources grants, low interest loans, and other assistance for both water and wastewater projects.
CONCURRENCES
The Community Development Department has reviewed the Plan for consistency with the
General Plan and supporting elements and concurs with the information provided.
FISCAL IMPACT
Adoption of the updated Urban Water Management Plan document does not directly create
additional fiscal impacts for the Water Fund. Any project or program that would stem from the
information contained in the Plan would be brought back to the City Council for approval as
appropriate.
