RECOMMENDATION
1. Receive a presentation on the 2020 Urban Water Management Plan and Water Shortage
Contingency Plan; and
2. Provide comments and direction to guide final Water Shortage Contingency Plan
development.
REPORT-IN-BRIEF
As an urban water supplier serving more than 3,000 water service connections, the City is
required to adopt and submit to the state Department of Water Resources (DWR) an Urban
Water Management Plan (UWMP) every five years. The City Council adopted the 2015 UWMP
on June 14, 2016 and is scheduled to consider the 2020 UWMP for adoption on June 15, 2021.
In this Study Session, staff will present 2020 UWMP and Water Shortage Contingency Plan
(WSCP) requirements, including a new requirement for a six-stage WSCP. Focus areas for City
Council discussion include water shortage management actions by stage, enforcement actions,
exemptions, and requirements for new development.
DISCUSSION
Current City Water Supply Status
With the recent rains, the City has over 17,000 acre-
feet of water in storage at Salinas Reservoir and its
proportional share of Whale Rock Reservoir is
15,553 acre-feet. The City has also requested its full
contractual allocation of 5,482 acre-feet of water
from Nacimiento Reservoir for 2021. Although the
region has seen below average rainfall recently, the
City has a diverse and reliable water supply with
more than ten years of water available under today’s
water supply and demand conditions.

Background
The California Urban Water Management Planning Act is a part of California Water Code
sections §10610-10656 and §10608 and requires urban water suppliers to adopt and submit an
updated plan to DWR every five years. Urban water suppliers are defined as agencies that
provide water for municipal purposes to more than 3,000 customers or supply more than 3,000
acre-feet of water annually (the City meets both criteria).
The City adopted its first UWMP in November 1994 and updated the UWMP in 2000, 2005,
2010, and 2016.1 The City Council adopted the 2015 UWMP by Resolution 10726 (Attachment
A) on June 14, 2016. By adopting a technically compliant UWMP, the City remains eligible for
State grants, low interest loans, and other assistance.
2020 UWMP Requirements
State legislation adopted in 2018 established new requirements for 2020 UWMPs, including
standardized requirements for water shortage contingency planning and drought risk
assessments. Under the State requirements, water suppliers must now plan for a dry period that
lasts for five consecutive years, an increase from the previous requirement of three years. Other
required elements of UWMPs include:
1. Assessment of the reliability of water supply sources over a 20-year time frame
2. A description of demand management measures, also known as conservation measures
3. A discussion of local water supplies, with a long-term forecast for each source, including
climate change
4. Demonstrated compliance with - Senate Bill X7-7 20202
5. A lay person’s description of water reliability
6. Incorporation of projected land use changes in demand forecasting
7. Seismic risk assessment and mitigation
8. A water energy analysis
9. Water savings from codes/standards/etc.
10. Five previous years of system water losses
The California Water Code requires that 2020 UWMPs are consistent with Groundwater
Sustainability Plans (GSP) in areas where those plans have been completed. As the City’s
Groundwater Sustainability Plan is not scheduled to be complete until 2022, and the City does
not depend on groundwater at this time, staff plans to include a schedule for GSP completion
within the 2020 UWMP, as well as the link to the City’s SGMA website.
Projecting Water Demand
To comply with State requirements, the City’s 2020 UWMP will look ahead twenty years to
project water demand through 2040. As this period extends beyond the 2035 horizon of the
City’s General Plan, staff will use population projections from the City’s Land Use Element of
57,200 persons in 2035 and assume a one percent population growth annually for five years to
2040. This projection yields a future population of 60,118 in 2040.
1 For the 2015 UWMP, the state legislature extended the filing deadline to July 1, 2016.
2 Senate Bill X7-7 is a California state law that requires the state to reduce urban water consumption by 20 percent
by the year 2020.
Item 3
Packet Page 28
Consideration of Climate Change
To comply with State requirements, the 2020 UWMP must consider climate change as it relates
to water use, water supply, resiliency, and drought risk. The City is well positioned to meet these
requirements by utilizing prior work efforts. The City first declared Climate Action a Major City
Goal during its 2017-19 Financial Plan.
On May 15, 2018, the City Council adopted Resolution 10893 amending the General Plan
WWME to reflect a 2,030-acre-foot per year reduction in available City water supply. The
amendment was a result of the 2018 update to the City’s safe annual yield computer model for
Whale Rock and Salinas Reservoirs which updated the model with climatic data from the
drought that ended in 2016 and local impacts of climate change3, consistent with WWME
program A 3.3.24 and program A 3.3.35.
Although this was a significant reduction in safe annual yield, the City has a multi-source water
supply capable of meeting the City’s future water demand (primary water supply and reliability
reserve) under the City’s General Plan. This analysis will be reflected in the 2020 UWMP as it
relates to climate change.
Water Shortage Contingency Plan (WSCP)
As part of the 2015 UWMP, the City modified its WSCP (Attachment B) which had not been
updated since 2000. The existing WSCP includes a monitoring stage and a five-staged demand
management response with each stage requiring more stringent Water Shortage Response
Actions (i.e., escalating water demand reductions). While the City’s WSCP is an important tool
to help plan for period of drought or loss of supply, it provides the flexibility for Counci l to take
the appropriate type and level of action needed in relation to the specifics of any type of water
shortage.
It is anticipated that as conservation programs mature, sources of supply are expanded, and the
community is engaged regarding drought, the WSCP will provide guidance on how to
appropriately respond to a water shortage. A specific scenario may require a mix of actions
contained within the plan or actions not considered within this plan.
The WSCP describes the City’s use of a water projection model to test both hypothetical and
actual water demand scenarios, to analyze current water storage at each reservoir, and to predict
how long the water supplies are available. The model accounts for the storage in the three
reservoirs, in conjunction with other available resources, needed to meet the City’s water
demand. The model uses historical hydrologic information based on the worst drought period
(2012 to 2014).
3 The City analyzed three climate change scenarios as part of the 2018 update to the safe annual yield model by the
U.S. Environmental Protection Agency, San Luis Obispo Council of Gover nments, and Nature Communications.
Each climate projection was applied to the historical dataset for Whale Rock and Salinas reservoir’s inflow,
precipitation, and evaporation. The City’s 2018 model was then used to calculate a revised safe annual yield
assuming these conditions had prevailed during the historical period of record.
4 WWME program A 3.3.2 states “The City will update the safe annual yield computer model for Salinas and Whale
Rock Reservoirs following severe drought periods to determine if any changes are necessary to the safe annual yield
amount.”
5 WWME program A 3.3.3 states “The City will monitor ongoing research on the potential for long-term impacts
associated with climate change to water supply resources.”
Item 3

The Water Code now includes standardized requirements for the 2020 WSCP including th e
following:
1. A Water Supply Reliability Analysis
2. Annual Water Supply and Demand Assessment Procedures
3. Six Standard Water Shortage Stages6
4. Shortage Response Actions
5. Communication Protocols
6. Legal Authority, Compliance, and Enforcement
7. Financial Consequences of WSCP
8. Monitoring and Reporting
9. WSCP Update Procedures
10. Special Water Feature Distinction
11. Plan Adoption, Submittal, and Availability
The City’s existing WSCP will need to be modified to comply with the 2020 requirements. As
shown in Table 3, staff proposes the addition of an Alert stage and the alignment with State
required reduction stages.

FOCUS AREAS FOR COUNCIL DISCUSSION
Although many of the legal mandates found in the UWMP and WSCP are highly prescriptive in
nature, the City has control over many elements of the two plans. Below are suggested focus
areas for City Council discussion at the Study Session.
6 Like in the 2015 UWMP, the City’s Monitor Stage is in place at all times to continue to monitor the City’s
compliance with water conservation mandates and goals.
7 General Plan, Water and Wastewater Management Element, Policy A 6.3.2 related to Short -term Water Shortages
states that “Mandatory water conservation measures as described in the City’s Water Shortage Contingency Plan,
included in the City’s Urban Water Management Plan, may be implemented when the City's water supplies are
projected to last five years or less.”
Item 3
Packet Page 30
Equitable Water Shortage Management Actions
When the City has less than five years of water available the WSCP requires Water Shortage
Management Actions (Management Actions) that increasingly reduce the community’s water
demand as water supplies are further stressed. Management Actions can also include bringing
new water supplies online such as an expansion of the City’s groundwater pumping program or
recycled water system expansion. The City has focused on Management Actions that are
equitable between residential and non-residential customer classes while ensuring that new
development being considered during drought periods does not further reduce the City’s
available water supplies. A comprehensive list of Management Actions, as well as additional
details about the proposed Water Shortage Contingency Plan, can be found in (Attachment C).
During the “Watch” and “Warning” stages, which occur when less than five and less than four
and one-half years of water supplies remain, the City focuses efforts on increased public
outreach and water conservation messaging to the community. Concurrently, the City
implements internal measures to ensure adequate staffing levels, budgets, rates, and work
programs are in place leading into the next four stages. The main differentiation between the
“Watch” and “Warning” stages is the implementation of time of use irrigation restrictions (No
irrigation between 7:00 AM and 7:00 PM) and the option to begin the Water Demand Offset
Program (Offset Program) within the “Warning” stage. The Offset Program requires
development projects that have not yet been through the entitlement process to offset their water
demand prior to connecting to the City’s water system. More detail on the Offset Program can be
found within the “New Development” focus item below.
The “Alert” stage, which is designated when the City has less than four years of available water
supply, provides additional irrigation restrictions. Specifically, this stage limits outdoor
irrigation to four days per week and requires new development that has not been through the
entitlement process to either defer landscape installations or to install landscaping that provides a
50 percent or greater reduction in Maximum Applied Water Allowance (MAWA). This stage
also includes large public outreach efforts to the community as staff prepare for more restrictive
measures in the final three stages.
The “Severe” stage occurs when the City’s available water supplies provide less than three and
one-half years of water to the community. During this stage, major changes include a reduction
in allowable watering days from four days per week to three days per week, the option for
Council to require a more stringent Offset Program (1.5:1 or 2:1 offset ratio), and the initiation of
the City’s Water Allotment Program. The Water Allotment Program sets a maximum water use
for each residential property based on the number of residents living in that home and allows
businesses to reduce water use by a percentage based on their business category or to a “baseline
consumption”. The intent of the initial stage of the Water Allotment Program is to restrict the
water use of the City’s most inefficient water users. It is important to understand that this
program does not give a larger volume of water to properties with larger yards or more irrigation
but rather ties the allotment to the number of people living within the home.
Item 3
Packet Page 31
The “Extreme” stage occurs when the City has less than three years of water supply available.
Notable actions in this stage include a reduction in allowable watering days from three days a
week to two days a week and a smaller per-person water allotment. A reduced per-person water
allotment would be based upon already achieved demand reduction and specific rainfall forecasts
and time of year.
The final stage of the WSCP, the “Critical Stage” occurs when the City has two and one-half
years or less of available water supply. Notable actions within this stage include the option to
cease outdoor irrigation and prohibit new connections to the City’s water system, as well as a
reduction in the City’s Water Allotment Program, allowing each residential property the
minimum amount of water to ensure the health and safety of the occupants.
Community Priorities and Water Shortage Action Exemptions
As the community was impacted by the 2011-2015 drought and irrigation restrictions were put
into place, community members advocated for certain exemptions related to water use
restrictions. Staff believes that a series of minor exemptions will help ensure the health and well -
being of the community while not making a substantial impact on available water supplies. Staff
supports the following water use restriction exemptions and variances:
Sites Using Recycled Water
Per the existing WSCP, sites utilizing recycled water are exempt from irrigation restr ictions.
These sites include major City parks, such as Damon Garcia Park, French Park, Islay Park,
Laguna Lake Park, Laguna Hills Park, De Vaul Park, the Laguna Lake Golf Course, and Laguna
Middle School, as well as many multifamily and commercial properti es. It is important to
acknowledge that all of the City’s recycled water customers are located on the southern side of
the City due to delivery limitations of the City’s recycled water system, thus not providing equal
opportunities for safe play and recreation across the community.
Irrigation Exceptions at Specific Facilities
During the most recent drought, Public Works Parks Maintenance staff and community members
provided feedback that City parks with inadequate irrigation allotments could lead to hazardous
conditions at recreation and play environments. To address these concerns, and to provide
communal spaces for recreation during times when many homes allowed landscapes to die, in
2016 the City Council approved an amendment to Chapter 13.07.030 of the Municipal Code,
allowing for daily irrigation at designated City facilities during turf renovation, and three times
per week thereafter (Attachment D). Staff recommends that this exemption be expanded to
include schools within the City’s boundaries as they are used for recreation in a similar manner
to City parks, specifically during school hours. As proposed, this exemption would only go into
place in the stages of the WSCP when irrigation days are restricted. It is anticipated that this
exemption would constitute a net increase of under 75 acre-feet per year versus no exemption.
This constitutes approximately 1.5 percent of the City’s total water use.
Item 3
Packet Page 32
Irrigation of Trees
During the 2011-2015 drought, the City heard from many customers who opted to cease
irrigation of their trees to reduce their water demand. Unlike turf, shrubs, and other groundcover,
trees take a great amount of time to grow and provide substantial ecological, environmental,
practical, and economic value to the community. Staff recommends an exemption to irrigation
restrictions to allow for the use of a hose and shutoff nozzle to hand water trees.
Hospitals, Healthcare Facilities, and other Specific Business Types
Staff proposes that hospitals, healthcare facilities, and other businesses requiring water for the
health and safety of at-risk people may apply for an exemption or allocation adjustment for
indoor water use on a case-by-case basis. This exemption may be granted at the discretion of the
Utilities Department Director or his/her/their designee.
New Development
The City utilized water demand offset programs in the past to continue to permit new
development during periods of restricted water availability. Water offset programs require new
development to conduct water savings projects within the City in order to offset the new demand
that is created by the project. An example of a highly successful water offset program was the
toilet retrofit offset program implemented by the City in the 1990s. As a result of this highly
successful program, most toilets in the City today meet low-flow requirements, thus limiting the
potential of future toilet retrofit offset programs.
While water offsets are identified in the City’s existing WSCP, staff is proposing an offset
program that begins as a “net neutral” water savings program in which new water demand must
be offset at a 1:1 ratio. During later stages of the WSCP staff recommends that the City Council
retain the ability to require a 1.5:1 and 2:1 “net benefit” water offset ratio. Examples of water
offsets include an in-lieu fee to support the City’s water supply expansion projects, indoor water
fixture replacements, and turf replacements. During the Critical stage of the WSCP, staff
recommends that no new connections to the City’s water system be permitted since water offsets
do not technically create more water, they simply expedite water supply and water conservation
programs, essentially making them happen sooner. The City must meet Water Code Section 350
and Government Code Section 65858 requirements to trigger a cessation in new connections,
otherwise commonly referred to as a “building moratorium”. While legally complex, for a
building moratorium to be legally sound, specific findings must be made to demonstrate a
“current and immediate threat to the public health, safety, or welfare, and that the approval of
additional subdivisions, use permits, variances, building permits, or any other applicable
entitlement for use which is required in order to comply with a zoning ordinance would resul t in
that threat to public health, safety, or welfare.”
Outreach to the Community
Communication on water resources remains important both during times of adequate water
availability and during water shortages. The community will benefit equally during rob ust water
supply periods, and any possible water shortage periods that may be experienced. Broadened
communication will be accomplished through expanded public outreach programs aimed at
educating and informing the public about the City’s water supplies and water resource
availability, planning and housing policies, and water resource and infrastructure resiliency.
Item 3
Packet Page 33
Methods staff utilize for public outreach include use of the City’s website and social media
platforms, attendance at community events such as Farmers’ Market, the SLO Home Exposition,
the Disaster Preparedness Exposition, and Earth Day, and in-person meetings with community
members to help them meet their water conservation goals. Additionally, staff will include
regular outreach on video and audio streaming services, television, radio, and through other paid
advertising and direct mail pieces such as the Resource Newsletter.
When entering periods of drought or water shortage, one of the most essential roles the City
plays is to ensure that the community has an overall awareness of the current situation and the
need for voluntary conservation measures in order to avoid more strict mandatory measures.
During a water shortage, defined as the City having less than five years of water available, the
City would expand its existing outreach program and more directly focus this outreach on
customer classes and water users with the largest potential for water savings. Increased outreach
is a time intensive activity and would require additional funding associated with this expanded
work effort.
Examples of the type of measures the City would take to increase outreach to the community
include but are not limited to the following:
• Increased presence at public events (Home Expo, Farmers Market, Earth Day, etc.)
• Increased direct contact with residential advocacy groups, business advocacy groups,
and irrigation industry groups
• Increased use of printed advertising such as newspapers, billing inserts, direct mail
• Use of radio and digital audio streaming service advertising (Spotify/Pandora)
• TV and digital video streaming advertising (YouTube)
• Use of visual cues such as banners, flyers, and signs in public spaces such as parks
and City offices
Enforcement Actions
Utilities Department staff is seldom required to assess financial penalties to customers who are in
violation of the City’s Municipal Code as most violations are not intentional and are easily
resolved. However, as the City learned in the 2011-2015 drought, more stringent restrictions can
result in customers choosing to not follow the City’s more restrictive demand reduction measures
during a water shortage, especially in the stages that require significant reductions in outdoor
irrigation.
The current process for reaching out to customers who are in violation is as follows:
First Violation (Courtesy Notification): Customer receives a “courtesy notification” by
staff regarding the violation that was observed, and the Water Shortage Response Actions
currently in place. The customer is provided with educational material and resources to
help them comply with the requirements, if possible. Examples of a “courtesy
notification” include door tags containing educational information, educational
pamphlets, mailed letters, and/or a phone call by staff.
Item 3
Packet Page 34
Second Violation (Issuance of Notice of Violation): Customer is issued a written notice
of violation (NOV), which describes the specific violation, date, and time the violation
was observed, and consequences of subsequent violations.
Subsequent Violations (Penalty/Fine): Customer may be issued a penalty/fine for
violation in accordance with the City’s Municipal Code.
As water supply declines and the community has more opportunity to understand and
implement new restrictions, staff recommends a penalty structure in which penalties for
violations double within the final two WSCP stages. Staff also recommends ceasing the use
of a “Courtesy Notification” during the final two WSCP stages.
Policy Context
The City’s General Plan Water and Wastewater Management Element Pr ogram A 5.3.3 requires
the City to “Prepare and update the Urban Water Management Plan every five years as
required by the State.”
The requirements for UWMPs are found in two sections of California Water Code, §10610-
10656 and §10608, which are available at the links below:
https://leginfo.legislature.ca.gov/faces/codes_displayexpandedbranch.xhtml?lawCode=WAT&di

https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=10608.&lawCo
de=WAT
The 2020 UWMP and WSCP are consistent with the City’s Charter and General Plan. Added in
1996, Section 909 (“Use of Reliability Reserve”) of the City’s Charter states:
As identified in the Water Management Element of the General Plan, the City shall
strive to acquire additional water supplies as a “reliability reserve” to protect the City
from future water shortages. Once the City has acquired a portion or all of the
reliability reserve, the additional water supply shall only be used to meet City needs
during unpredictable changes such as a new worst-case drought, loss of one of the
City’s water sources, contamination of a source, or failure of a new source to provide
projected yield, and not to allow additional development.
The City’s General Plan, Water and Wastewater Management Element, Policy A 5.2.3 provides
the methodology for determining the City’s reliability reserve. The policy states “The City will
establish a reliability reserve that is 20-percent of the water use rate established in Policy A
5.2.18 multiplied by the current population. The water supply designated as the reliability
reserve may not be used to serve future development.”
8 General Plan, Water and Wastewater Management Element, Policy A 5.2.1 states “The City will utilize the per
capita water use rate allowed by Senate Bill X7-7 for projecting future potable water demand established as 117
gallons per capita per day.”

Chapter 8: Water Shortage Contingency Plan
Developing and maintaining a multi-source water supply portfolio to increase resiliency against water
shortages has been a City priority for many years. A water shortage occurs when water supplies are
insufficient to support demand. A water shortage could occur due to drought, earthquake, infrastructure
failure, or other emergency. Droughts occur with unpredictable frequency, intensity, and duration. The
Department of W ater Resources defines drought as “A deficiency of precipitation over an extended period
of time resulting in a water shortage for some activity, group, or environmental sector.”
This Water Shortage Contingency Plan (WSCP) provides the foundation for a staged response to
worsening water shortage conditions. A draft Water Conservation Ordinance, to update Chapter 13.07 of
the City’s Municipal Code, is proposed to establish the regulations and procedures for implementing this
Plan. The draft Water Conservation Ordinance is provided in Appendix VI.
8.1 WATER SHORTAGE DETERMINATION
The degree of the water supply shortage determines the necessary level of response from the City and
customers. When determining a water shortage stage the City evaluates the following:
• Water demand across customer categories
• Water availability at each supply source
• Available water supply options including supplemental water supplies
The City utilizes a water projection model, testing both hypothetical and actual water demand scenarios,
to analyze current water storage at each reservoir and to predict how long the water supplies are
available. The model accounts for the total storage in the three reservoirs, in conjunction with other
available resources, needed to meet the City’s
water demand. The model uses historical hydrologic
information based on the average for the worst
drought period (2012 to 2014). Other data included
in the model are:
• Water Entitlement (contractual or
percentage)
• Current reservoir level
• Gallons per capita per day water demand
• Rainfall
• Temperature
• Evaporation
• Existing population
• Future population growth
Utilizing a water projection model as part of its
water supply management enables the City to
foresee whether a water supply shortage is
anticipated in any given year, and the severity of a
shortage based on the availability of the City’s
different sources of supply and water demand
trends. The City uses the model to study the
potential impacts of climate change using increased
temperature and evaporation rates, along with
decreased precipitation.

8.2 WATER SHORTAGE RESPONSE
A water shortage response relies on the City’s ability to temporarily augment supply and/or reduce water
demand. The City’s water shortage response would combine a variety of elements from outreach to
enforcement, each increasing in intensity as the shortage persists. The City’s demand reduction targets
focus on water use limits and prohibitions that will reduce non-essential use, such as imposition of
restrictions on outdoor irrigation. Implementation of these restrictions is necessary to conserve the City’s
water supply for the greatest public benefit regarding domestic use, sanitation and fire protection. This
section reviews the general strategies the City will employ to mitigate the impacts of water shortage on
the community.
Voluntary Reduction Measures
All customers may be asked to voluntarily reduce their water usage during a water shortage. The City
may provide water conservation tips and suggestions through various public outreach methods,
encourage and distribute conservation devices such as low flow shower heads and faucet aerators,
discourage excessive outdoor watering, and encourage landscaping with drought tolerant plants.
Voluntary reductions measures are described in more detail in Section 8.3
Mandatory Reduction Measures
The City may place mandatory reduction measures on certain uses, such as restricting outdoor watering
to prescribed times and number of days per week beginning in the Watch Stage, with days and times for
landscape watering further limited in later stages. Mandatory reduction measures may limit specific
methods of irrigation (i.e., sprinkler ban).
The seasonal increase in water demand underscores the importance of implementing outdoor landscape‐
focused reduction programs. An average of approximately 50 percent of residential water use in San Luis
Obispo is for landscape irrigation. Therefore, restrictions on outdoor water use are generally highly
effective in reducing water demand. Outdoor uses are typically considered to be discretionary or
nonessential for health and safety purposes, are highly visible and relatively easy to monitor, and often
are a substantial component of water demand, particularly during the summer months when drought
conditions are often most severe.
Prohibitions
Prohibitions will vary by drought stage, with the fundamental purpose of prohibiting non‐essential uses not
required for basic health and safety. During a declared water shortage, specific prohibitions would be
described in a Water Shortage Ordinance adopted by the City Council. In the Critical Stage, all non‐
essential outdoor water use, except recycled water or grey water, may be prohibited.
The City will adopt regulations at the appropriate water shortage stage that require customers to take
certain measures to promote water conservation, such as posting signage at various establishments,
undergoing a water audit to maximize or demonstrate water conservation, and prescribing to customer‐
specific water budgets.
Supplemental Water Supply Options
During a water shortage emergency, the City may also utilize supplemental water supply options, or
acquiring a new supply as warranted by the current situation. Currently, this might include requesting all
5,482 afy of the City’s Nacimiento Reservoir allocation. In the future, this may include utilizing more
groundwater and/or utilizing highly treated wastewater in a potable reuse system. These water supply
options may be less desirable during normal operations due to increased operation costs.
8.3 WATER SHORTAGE STAGES
The goals of the City’s Water Shortage Contingency Plan are to extend the City’s available water
resources long enough to gain another winter rainfall period which could serve to add to reservoir
storage. Extending available water resources through water demand reduction provides time for the City
to bring on supplemental water supplies to meet demand. It is the City’s goal to implement water demand
reduction programs that will achieve measurable water savings without affecting customers’ lifestyles. In
the higher water shortage stages lifestyle and habit changes will be necessary.
Item 3
Packet Page 41
2015 Urban Water Management Plan
8-3
This section identifies the measures that may be taken at each stage to achieve desired water use
reduction levels. The purpose of establishing water shortage stages is to clearly define the severity of the
shortage and establish appropriate targets for demand reductions. Defining these stages allows the City
to respond to worsening conditions, with each stage “triggering” different actions. The multi‐stage
approach provides different levels of response for a water shortage event ranging from a ten percent
supply deficiency up to a 50 percent or greater deficiency.
Table 32 provides a quick reference guide to the City’s Water Shortage Contingency Plan, though City
Council may adopt variations of these stages, independent from the stage resulting from the use of the
Water Projection Model, to strategically address the current water shortage situation. Each stage
describes increasing levels of water demand reduction and water supply augmentation methods. As
stated previously, during an actual water shortage emergency, other measures may be imposed.
Water Shortage Response Stage: MONITOR
San Luis Obispo has made water conservation an integral part of the community’s culture and policy
context for managing its water resources. The community has demonstrated a high commitment to
reducing its water usage during water shortages. Although not a true declaration of a water shortage, the
Water Shortage Contingency Plan’s Monitor Stage remains in place at all times along with voluntary
conservation and implementation of the California Urban Water Conservation Council’s Best
Management Practices. A complete description of the City’s water conservation program is included in
Chapter 7.
This stage is focused on achieving voluntary compliance, as opposed to a mandatory demand reduction
programs. To ensure the City is using water responsibly and remains in compliance with the SB X7-7
requirement to not exceed 117 gpcd, the City continually assesses available water supply levels, monitors
customer water demand trends, conducts water loss audits, and evaluates potential supplemental
supplies. The following are examples of measures that may be taken to facilitate water conservation
consistent with CUWCC best management practices:
• Implement public outreach and communication programs (bill stuffers, social media, etc.)
• Participate in trade shows, home shows, and special community events
• Identify largest water users in each sector and offer complementary water audits
• Identify and notify customers of possible leaks and inefficient uses of water
• Encourage the use of drip irrigation and drought tolerant plants
• Implement school (K-12) education programs related to water conservation
• Enforce the toilet retrofit upon sale program
•
Actions at the Monitor Stage would also include active enforcement of the City’s water waste prohibitions,
such as those adopted by the Governor in 2016, from Chapter 13.07 of the City’s Municipal Code, which
defines water waste as follow (See also Table 32):
13.07.020 – Water runoff prohibited.
A. No person shall cause any water delivered by the city water system to flow away from property owned,
occupied or controlled by such person in any gutter, ditch or in any other manner over the surface of the
ground, so as to constitute water waste runoff.
B. “Water waste runoff” means water flowing away from property and which is caused by excessive
application(s) of water beyond reasonable or practical flow rates, water volumes or duration of application.
(Ord. 1089 § 1 (part), 1987)

Water Shortage Response Stage: WATCH
When the City’s available water supply would provide less than five years of water, a recommendation
would be made to the City Council that a water shortage be declared. The City Council would be asked to
adopt a resolution declaring the City enter the Watch Stage and urge the public to reduce water use by
approximately 8.5 percent from 117 gpcd to 107 gpcd.
During the “Watch” Stage, the demand management measures utilized during the Monitor Stage above
will increase along with a continued focus on voluntary compliance. The City will also increase public
outreach, implement system and operational changes, increase enforcement actions, and undertake
other administrative actions. These program expansions and changes may include:
Water Demand Reduction Programs:
• Accelerate water audit programs for all customer classes
• Identify largest water users in each sector and contact for complementary water audits
• Increase water waste patrols
• Conduct water use surveys
• Implement rebate programs
• Consider the use of irrigation limitations
Public Outreach Programs:
• Issue a press release following Watch Stage declaration
• Include information in quarterly Resource Newsletter
• Update City website and create a page dedicated to information on details of WSCP Watch Stage
• Consider use of billing inserts to notify public of current situation and needs
• Coordinate with regional partners on messaging and outreach
• Develop outreach program for City staff to promote consistent messaging related to water supply
and water conservation
• Increase outreach at public events such as Farmers Market, SLO Home Show, and home owners
association board meetings
• Focus social media platforms on issues consistent with needed demand reductions
System and Operational Changes:
• Reduce water usage for main flushing and hydrant flushing
• Reduce distribution system pressure where feasible
• Increase leak detection, water meter testing, and water meter replacement
• Decrease allowable time for repairing leaks in distribution system
• Require use of non-potable water sources for all street sweeping and hydrocleaning
• Activate the Drought Taskforce
Enforcement Actions:
• Actively enforce water waste prohibitions
• Update online forms for reporting water waste and move forms to front page of website
• Continue to follow City’s policy for code violations and issue Notices of Violation and
Administrative Citations where deemed necessary
Other Administrative Actions:
• Begin drafting ordinance revisions and code changes that would go into effect in subsequent
water shortage stages
• Plan for the funding and implementation of specific conservation programs launched in
subsequent water shortage stages
Item 3
Packet Page 44

• Review potential fiscal impacts of drought (i.e., increased water supply, operational, and capital
costs); and demand reductions (reduced revenue)
• Prepare for implementation of next water shortage stage
• Identify and plan for the need for additional staff. In planning for additional staff, consideration
should be given to funding, available office space, vehicles, training, and other needed supplies
and support
• Consider need for drought surcharge to stabilize revenue
• Consider deferring previously scheduled capital projects as necessary to invest in acquisition of
needed water supply sources and demand reductions
• Review available supplemental water supply options, such as increased use of groundwater,
utilization of potable reuse, and implementation of a recycled water filling station
Water Shortage Response Stage: WARNING
When the City’s available water supply would provide less than four years of water, a recommendation
would be made to the City Council to move to the next water shortage stage. The City Council could be
asked to adopt a resolution declaring the City enter the Warning Stage and urge the public to reduce
water use by an additional approximately 11 percent from 107 gpcd to 95 gpcd including mandatory
conservation measures.
The water conservation measures described in the Monitor and Watch Stages above may increase during
the Warning Stage, with an increased focus on limiting outdoor water uses. System and operational
changes would remain in place. These increases and additions to programs may include:
Water Demand Reduction Programs:
• Continue implementation of and possible increase of all demand reduction programs listed in
Watch Stage
• Limit outdoor watering to two or three days a week and only between the hours of 7:00 p.m. and
7:00 a.m.
• Defer landscape installations for new development or require development to install landscaping
that provides a significant reduction in water demand ( e.g. a minimum of 50%) as compared to a
conventional drought tolerant landscaping during normal water years
• Require hotels/motels/inns to offer the option to opt out of laundry services
• Require restaurants to only serve water upon request
• Restrict use of decorative water features and fountains
• No watering within 48 hours of measureable rainfall
• No washing down of sidewalks, driveways, parking lots or other hardscape areas unless
necessary to protect public health and safety
• No exterior washing of buildings, dwelling and other structures, except for pre-approved uses
• No vehicles washing except at commercial car washing facilities or by use of a bucket and/or
hose equipped with a shut off nozzle
Public Outreach Programs:
• Continue implementation of and possible increase of all public outreach programs listed in Watch
Stage
• Issue a press release following Warning Stage declaration
• Target outreach to customers with large landscapes regarding irrigation restrictions
• Use of billing inserts, postcards, and direct mail pieces to inform customers of new requirements
and prohibitions
• Coordinate with local business groups such as the Chamber of Commerce and landscaping
associations to help encourage conservation among commercial customers
Item 3
Packet Page 45
2015 Urban Water Management Plan
8-7
• Coordinate with home owners associations, property rental agencies, and other local groups to
help encourage conservation among residential customers
Increased Enforcement Actions:
• First Violation: Customer notification and education
Customer will be notified by staff of the particular violation observed, and the demand reduction
programs currently in place. The customer will be provided with needed resources to help them
comply with requirements. Examples of notification include: door tags containing violation
information, mailed letter, and/or personal phone call by staff
• Second Violation: Issuance of Notice of Violation
Customer will be issued a written notice of violation (NOV), notifying the customer of specific
violation, date and time the violation was observed, and consequences of subsequent violations
• Subsequent Violations: Customer may be issued a penalty/fine for violation
Other Administrative Actions:
• Continue implementation of and possible increase of all
other administrative actions listed in Watch Stage
• Prepare utility billing system and bill format for water
allocations and reductions listed in subsequent stages.
• Establish appeals committee for customers who
exceed allotments in subsequent stages or receive
fines from violating water waste prohibitions
• Increase utility billing training and support to address
additional requirements of Warning Stage and future
stages
• Begin preparing for Severe Stage
Implementation of a Water Demand Offset Program:
During the Warning Stage, the City may consider implementing
a water demand offset program. Water demand offset
programs are designed to require new development that
causes increased water demand to offset such demand through
conservation or acquisition/development of new supplies. The
goal of an offset program is to ensure that a new development
does not increase current and future water demands.
At the Warning stage the City may choose to implement a neutral offset program, requiring that new
demands offset usage at a rate of 1:1. Future stages of the WSCP may suggest a more aggressive, “net
positive” water demand offset program. A “net positive” water demand offset program would require a
positive offset of a project’s water demand. An example of this would be a project required to offset its
water demand at a ratio higher than 1:1, such as 1.5:1 or 2:1.
There are several types of offset programs in use across California and the United States. Examples of
potential offset programs are listed below.
• Toilet replacements
• Smart irrigation controllers
• Onsite reuse systems
• Submetering
• In-lieu fee
• Irrigation system retrofits
• Waterless urinals
• Rainwater capture

Water Shortage Response Stage: SEVERE
When the City’s available water supply would provide less than three years of water, a recommendation
would be made to the City Council to move to the next water shortage stage. The City Council would be
asked to adopt a resolution declaring the City enter the Severe Stage and urge the public to reduce water
use by an additional approximately five percent from 95 gpcd to 90 gpcd.
At this water shortage response stage, the City would continue implementation of demand reduction,
public outreach, and enforcement programs described in prior stages. System and operational changes
would remain in place. At the Severe Stage, a water offset program may increase to a “net positive”
program, such as 1.5:1 or 2:1 and the City may implement a water allotment program. The following
allotment method may be used:
Customer Classification Severe Stage Allotment
Single Family Residential and
Multi-family Residential
A per capita allotment of 64 gppd,
verification of persons per household may
be requested
Commercial and Institutional Baseline allocation or allocation based on
percent reduction from normal usage
Landscape Meters
Allocation based on percent reduction from
normal usage; the City could consider
prohibiting outdoor irrigation
Excessive water use penalties may be imposed as outlined in the City’s Municipal Code.
At this stage, due to the limited water supplies that remain, the City could consider prohibiting outdoor
irrigation and the cessation of new connections to the water distribution system.
Water Shortage Response Stage: EXTREME
When the City’s available water supply would provide less than two years of water, a recommendation
would be made to the City Council to move to the next water shortage stage. The City Council would be
asked to adopt a resolution declaring the City enter the Extreme Stage and urge the public to reduce
water use by an additional approximately five percent from 90 gpcd to 85 gpcd.
At this water shortage response stage, the City would continue implementation of demand reduction,
public outreach, and enforcement programs described in prior stages. System and operational changes
would remain in place. At the Extreme Stage, a “net positive” water offset program may continue to be
offered and outdoor irrigation may be prohibited. The following allotment method may be used:
Customer Classification Extreme Stage Allotment
Single Family Residential and
Multi-family Residential
A per capita allotment of 56 gppd,
verification of persons per household
may be requested
Commercial and Institutional
Baseline allocation or allocation
based on percent reduction from

Excessive water use penalties may continue to be imposed as outlined in the City’s Municipal Code.
At this stage, due to the limited water supplies that remain, the City could consider the cessation of new
connections to the water distribution system.

Water Shortage Response Stage: CRITICAL
When the City’s available water supply would provide less than one year of water, a recommendation
would be made to the City Council to move to the next water shortage stage. The City Council would be
asked to adopt a resolution declaring the City enter the Critical Stage and urge the public to reduce water
use by an additional approximately 12 percent from 85 gpcd to 75 gpcd.
At this water shortage response stage, the City would continue implementation of demand reduction,
public outreach, and enforcement programs described in prior stages. System and operational changes
would remain in place. At the Critical Stage, a water offset program may no longer be offered and outdoor
irrigation may continue to be prohibited. The following allotment method may be used:
Customer Classification Critical Stage Allotment
Single Family Residential and
Multi-family Residential
A per capita allotment of 48 gppd,
verification of persons per household
may be requested
Commercial and Institutional
Baseline allocation or allocation
based on percent reduction from
normal usage
Excessive water use penalties may continue to be imposed as outlined in the City’s Municipal Code.
At this stage, due to the limited water supplies that remain, the City would consider the cessation of new
connections to the water distribution system.
8.4 REVENUE AND EXPENDITURE IMPACTS
During a water shortage, revenues from water sales can be reduced but the City’s operations and
maintenance costs would not reduce accordingly. In fact, during the these periods, the City’s operations
budgets can increase due to the implementation of water demand reduction measures, public outreach,
enforcement, groundwater exploration, water quality concerns, and other actions taken by the City during
the crisis. The reduction in revenues resulting from decreased water use may result in the need to raise
water rates during that period.
Under the City’s water rate structure, bills are based mainly on customer usage choices and resulting
demand on the water systems. Water Fund revenue is collected from multiple sources, but approximately
90 percent of revenue is directly tied to water service charges including the base fee.
To minimize the need to raise rates during water shortages, the City has a policy that requires a minimum
reserve of twenty percent of the Water Fund’s operating budget. While this is a minimum amount, the
reserve amount is typically above this minimum policy level.
City staff provides ongoing tracking of revenues and evaluates the potential impacts associated with
changes in water demand assumptions used in the Annual Water Fund Analysis. The City Council
considers the water rates necessary to provide water service to the community on an annual basis and
approves water rate changes as needed.
As part of the 2015-17 Financial Plan, the City included a base fee and tiered drought surcharge as water
demand was projected to reduce by 12 percent as a result of State water use reduction mandates. The
surcharge was proposed to offset the loss in revenue associated with the State order as the City was still
responsible for the costs of the City’s multi-source water supply and debt payments. In addition to water
supply, Water Fund revenue supports ongoing maintenance and operating programs needed to ensure
Item 3
Packet Page 48
2015 Urban Water Management Plan
8-10
that the water treatment and delivery systems meet all federal and state water treatment regulations and
are operated and maintained to provide safe and reliable service.
8.5 CATASTROPHIC WATER SUPPLY INTERRUPTION
The City has an Emergency Response Plan to cover a variety of potential disasters including:
earthquakes, floods, wildland fires, etc. The Plan identifies resources available to the City from other
agencies or private companies in the area. Additionally, the City of Morro Bay and the Whale Rock
Commission (of which the City of San Luis Obispo is a member) executed an agreement in June of 2000
which provides for Mutual Aid between the agencies during disruption of water deliveries or lack of
available water supplies. The agreement provides a general framework for exchanging water between
agencies in the event of emergencies or other water disruptions. The agreement is voluntary based on
each agency’s ability to assist at any point in the future.
In relation to providing water service, the City would utilize portable generators to minimize water
disruptions during an extended power outage. These generators are maintained and available to the City
at any time and are stored at the City Corporation Yard.
The City is a member of the Water Agency Response Network (WARN). WARN is a statewide
organization of water agencies and companies that have entered into a mutual aid agreement to assist
other water agencies during emergencies or other water related situations. The agreement provides the
frame work for providing assistance and provides a key contact to initiate a multiple agency response to a
water emergency situation.
8.6 MINIMUM SUPPLY NEXT THREE YEARS
Consistent with section 6.6, Water Supply Reliability Analysis, in Chapter 6, the City’s multiple dry year
scenario was determined to be 2012 to 2014 as the combined rainfall total for those three years was the
lowest on record. Available water supplies during this period assume the City’s safe annual yield from
Salinas and Whale Rock Reservoirs, contractual supply from Nacimiento Reservoir, and recycled water
supply are available totaling 12,622 acre feet of available supply, as shown in Table 33.
As directed by DWR, this section was prepared based on what is known by the City at the time the
UWMP was prepared. After the current drought has a “bookend” the safe annual yield of Salinas and
Whale Rock reservoirs will be recalculated. Related changes to safe annual yield will be incorporated into
planning scenarios.

Draft 2020 Water Shortage Contingency Plan
WSCP-1
Draft 2020 Water Shortage Contingency Plan
Developing and maintaining a multi-source water supply portfolio to increase resiliency against water
shortages has been a City priority for many years. A water shortage could occur due to drought, earthquake,
infrastructure failure, or other emergency. Droughts may occur with unpredictable frequency, intensity, and
duration. The Department of Water Resources defines drought as “A deficiency of precipitation over an
extended period of time resulting in a water shortage for some activity, group, or environmental sector.”
This Water Shortage Contingency Plan (WSCP) provides the foundation for a staged response to
worsening water shortage conditions. A draft Water Conservation Ordinance, to update Chapter 13.07 of
the City’s Municipal Code, will be proposed to establish the regulations and procedures for implementing
this Plan.
1. WATER SUPPLY RELIABILITY ANALYSIS
Assessing water supply reliability is the fundamental purpose of the City’s Urban Water Management Plan
(UWMP). Water service reliability is the City’s ability to meet the water needs of its customers under varying
conditions. Chapter 6 of the City’s UWMP assesses water supply reliability by analyzing plausible
hydrological variability, regulatory variability, climate conditions, and other factors that may affect the City’s
water supplies and customer water uses. The analysis looks beyond the City’s past experience and
considers what could be reasonably foreseeable in the future.
2. ANNUAL WATER SHORTAGE ASSESSMENT
The City performs a water shortage assessment each year, and more frequently in drought conditions, to
review available water supplies and confirm its approach for the coming year. The degree of the water
supply shortage determines the necessary level of response from the City and customers, if any. This
assessment includes evaluation of the following:
a. Current year water demand across customer categories
b. Water availability at each supply source
c. Available supplemental water supply options
d. Infrastructure considerations, including planned maintenance, repairs, and upgrades
The City utilizes a water projection model, testing both hypothetical and actual water demand scenarios to
analyze and predict how long the water supplies will be available under specific conditions. The model
accounts for the storage in the three reservoirs, in conjunction with other available resources, needed to
meet the City’s water demand. The model uses historical hydrologic information based on the average for
the worst drought period (2012 to 2014). Other data included in the model is:
a. Water Entitlement (contractual or percentage)
b. Current reservoir levels
c. Average gallons per capita per day community water demand
d. Rainfall
e. Temperature
f. Evaporation
g. Existing population
h. Population growth
Utilizing a water projection model as part of its water supply management enables the City to foresee
whether a water supply shortage is anticipated in any given year, and the severity of a shortage based on
the availability of the City’s different sources of supply and water demand trends. The City uses the model
to study the potential impacts of various intensities of drought conditions, including increased temperature
and evaporation rates, along with decreased precipitation.
In accordance with new UWMP requirements, each year the City will prepare a water supply and demand
assessment, present it to the City Council for review, and submit its annual Water Shortage Assessment
Item 3
Packet Page 53
Draft 2020 Water Shortage Contingency Plan
WSCP-2
Report to DWR. The Assessment will be conducted based on the use of the City’s water projection model
and the key data inputs described above to characterize near-term water supply conditions (i.e., for the
next 12 months).
3. WATER SHORTAGE RESPONSE
A water shortage response is dependent on the City’s ability to temporarily augment supply and/or reduce
water demand. The City’s water shortage response would combine a variety of elements from outreach to
enforcement, each increasing in intensity as the shortage persists. The City’s demand reduction targets
focus on water use limits and prohibitions that will reduce non-essential use, such as imposition of
restrictions on outdoor irrigation. Implementation of these restrictions is necessary to conserve the City’s
water supply for the greatest public benefit regarding domestic use, sanitation, and fire protection. This
section reviews the general strategies the City will employ to mitigate the impacts of water shortage on the
community.
Voluntary Reduction Measures
All customers may be asked to voluntarily reduce their water usage during a water shortage. The City may
provide water conservation tips and suggestions through various public outreach methods, encourage and
distribute conservation devices such as low flow shower heads and faucet aerators, discourage excessive
outdoor watering, and encourage landscaping with drought tolerant plants. Voluntary reductions measures
are described in more detail in Section 3.
Mandatory Reduction Measures
The City may place mandatory reduction measures on certain uses, such as restricting outdoor watering to
prescribed times and number of days per week beginning in the Warning Stage, with days and times for
landscape watering further limited in later stages. Mandatory reduction measures may limit specific
methods of irrigation (i.e., sprinkler ban).
The seasonal increase in water demand underscores the importance of implementing outdoor irrigation‐
focused reduction programs. An average of approximately 50 percent of residential water use in San Luis
Obispo is for landscape irrigation. Therefore, restrictions on outdoor water use are generally highly effective
in reducing water demand. Many outdoor uses are considered discretionary, or nonessential for health and
safety purposes, are highly visible and relatively easy to monitor, and often are a substantial component of
water demand, particularly during the summer months when drought conditions are often most severe.
Water Use Prohibitions
Water use prohibitions will vary by drought stage, with the fundamental purpose of restricting or prohibiting
non‐essential uses that are not required for basic health and safety. During a declared water shortage,
specific prohibitions would be described in a Water Shortage Ordinance adopted by the City Council. In the
Critical Stage, all non‐essential outdoor water use, except recycled water or grey water, may be prohibited.
The City will adopt regulations at the appropriate water shortage stage to promote water conservation, such
as posting signage at various establishments, offering water audits to maximize water conservation, and
prescribing to customer‐specific water budgets (i.e., water allocations).
Supplemental Water Supply Options
During a declared water shortage emergency, the City may also utilize supplemental water supply options,
or acquire a new supply as warranted by the current situation. This may include utilizing more groundwater
and/or utilizing highly treated wastewater in a potable reuse system. These water supply options may be
less desirable during normal operations due to increased operational costs.

WSCP-3
4. WATER SHORTAGE STAGES
The goals of the WSCP are to extend the City’s available water resources long enough to gain another
winter rainfall period which could serve to add to reservoir storage. Extending available water resources
through water demand reduction provides time for the City to bring on supplemental water supplies to meet
demand. It is the City’s goal to implement water demand reduction programs that will achieve measurable
water savings without requiring customers to make significant lifestyle changes. In the more advanced
water shortage stages lifestyle and habit changes will be necessary.
This section identifies the measures that may be taken at each stage to achieve desired water use reduction
levels. The purpose of establishing water shortage stages is to clearly define the severity of the shortage
and establish appropriate targets for demand reductions. Defining these stages allows the City to respond
to worsening conditions, with each stage “triggering” different actions. The multi‐stage approach provides
different levels of response for a water shortage event ranging from a ten percent supply deficiency up to a
50 percent or greater deficiency.
Table 1 provides a quick reference guide to the WSCP, though City Council may adopt variations of these
Water Shortage Response Actions, independent from the stage resulting from the use of the Water
Projection Model, to strategically address the current water shortage situation. Each stage describes
increasing levels of water demand reduction and water supply augmentation methods. As stated previously,
during an actual water shortage emergency, other measures may be imposed.

Water Shortage Response Stage: MONITOR
San Luis Obispo has made water conservation an integral part of the community’s culture and policy context
for managing its water resources. The community has demonstrated a high commitment to reducing its
water usage during water shortages. Although not a true declaration of a water shortage, the Water
Shortage Contingency Plan’s Monitor Stage remains in place at all times along with voluntary conservation.
This stage is focused on achieving voluntary water savings, as opposed to a mandatory demand reduction
programs. To ensure the City is using water responsibly and remaining in compliance with water efficiency
goals are regulations, the City continually assesses available water supply levels, monitors customer water
demand trends, conducts water loss audits, and evaluates potential supplemental supply projects. The
following are examples of measures that may be taken to maintain water use efficiency goals:
1. Implement public outreach and communication programs (bill stuffers, social media, etc.)
2. Participate in trade shows, home shows, and special community events
3. Offer complimentary water audits
4. Identify and notify customers of possible leaks and inefficient uses of water
5. Encourage the use of drip irrigation and drought tolerant plants
6. Implement school (K-12) education programs related to water conservation
7. Enforce the water efficiency retrofit program (toilet retrofit upon sale program)
Actions at the Monitor Stage would also include active enforcement of the City’s water waste prohibitions,
such as those from Chapter 13.07 of the City’s Municipal Code, which defines water waste as follow (See
also Table 1):
Water Shortage Response Stage: WATCH
When the City’s available water supply would provide less than five years of water, a recommendation
would be made to the City Council that a water shortage be declared. The City Council would be
recommended to adopt a resolution declaring the City enter the Watch Stage and urge the public to reduce
water use by approximately ten percent.
During the “Watch” Stage, the demand management measures utilized during the Monitor Stage above will
increase along with a continued focus on voluntary water use reduction. The City will also increase public
outreach, implement system and operational changes, increase enforcement actions and patrols, and
undertake other administrative actions. These program expansions and changes may include:
City of San Luis Obispo, Municipal Code
13.07.020 – Water runoff prohibited.
A. No person shall cause any water delivered by the city water system to flow away
from property owned, occupied or controlled by such person in any gutter, ditch or
in any other manner over the surface of the ground, so as to constitute water waste
runoff.
B. “Water waste runoff” means water flowing away from property and which is caused
by excessive application(s) of water beyond reasonable or practical flow rates,
water volumes or duration of application. (Ord. 1089 § 1 (part), 1987)

Item 3
Packet Page 58
Draft 2020 Water Shortage Contingency Plan
WSCP-7
G. Review available supplemental water supply options, such as increased use of groundwater,
utilization of potable reuse, and implementation of a recycled water filling station
Water Shortage Response Stage: WARNING
When the City’s available water supply would provide less than 4.5 years of water, a recommendation
would be made to the City Council to move to the Warning water shortage stage. The City Council could
be recommended to adopt a resolution declaring the City enter the Warning Stage and urge the public to
reduce water use by an additional 10 percent including mandatory conservation measures.
The water conservation measures described in the Monitor and Watch Stages above may increase during
the Warning Stage, with an increased focus on limiting outdoor water uses. System and operational
changes would remain in place. These increases and additions to programs may include:
1. Water Demand Reduction Programs:
A. Continue implementation of and possible increase of all demand reduction programs listed in Watch
Stage
B. Limit outdoor watering to between the hours of 7:00 p.m. and 7:00 a.m.
C. Require restaurants to only serve water upon request
D. Restrict use of decorative water features and fountains
2. Public Outreach Programs:
A. Continue implementation of and possible increase of all public outreach programs listed in Watch
Stage
B. Issue a press release following Warning Stage declaration
C. Target outreach to customers with large landscapes regarding irrigation restrictions
D. Use of billing inserts, postcards, and direct mail pieces to inform customers of new requirements
and prohibitions
E. Coordinate with local business groups such as the Chamber of Commerce and landscaping
associations to help encourage conservation among commercial customers
F. Coordinate with homeowners associations, property rental agencies, and other local groups to help
encourage conservation among residential customers
3. Enforcement Actions (Same as previous stage)
4. Other Administrative Actions:
A. Continue implementation of and possible increase of all other administrative actions listed in Watch
Stage
B. Begin preparing for the Alert Stage.
5. Optional Implementation of a Water Demand Offset Program:
During the Warning Stage, staff will begin updating the Water Demand Offset Program and messaging
about the program to the development community. The City may consider implementing a water
demand offset program during this stage. Water demand offset programs are designed to require new
development that causes increased water demand to offset such demand through conservation or
acquisition/development of new water supplies. The goal of an offset program is to ensure that new
development does not increase current water demands. It should be noted that offset programs simply
expedite water efficiency measures and thus create water savings in the short term. Depending on the
nature of the offset, long-term savings may not be realized.
At the Warning stage the City may choose to implement a “net neutral” offset program, requiring that
new demands offset usage at a rate of 1:1. Future stages of the WSCP may suggest a more aggressive,
Item 3
Packet Page 59
Draft 2020 Water Shortage Contingency Plan
WSCP-8
“net positive” water demand offset program. A “net positive” water demand offset program would require
a positive offset of a project’s water demand. An example of this would be a project required to offset
its water demand at a ratio higher than 1:1, such as 2:1 or 3:1.
There are several types of offset programs in use across California and the United States. Examples
of potential offset programs are listed below.
A. Toilet replacements
B. Smart irrigation controllers
C. Submetering
D. In-lieu fees (fees are used to support new water supply projects)
E. Irrigation system retrofits
F. Waterless urinals
G. Rainwater capture
H. Recycled Water Retrofit Projects
Water Shortage Response Stage: ALERT
When the City’s available water supply would provide less than four years of water, a recommendation
would be made to the City Council to move to the Alert water shortage stage. The City Council could be
recommended to adopt a resolution declaring the City enter the Alert Stage and urge the public to reduce
water use by an additional 10 percent including mandatory conservation measures.
The water conservation measures described in the Stages above may increase during the Alert Stage, with
an increased focus on limiting outdoor water uses. System and operational changes would remain in place.
These increases and additions to programs may include:
1. Water Demand Reduction Programs:
A. Limit outdoor watering to four days a week and only between the hours of 7:00 PM and 7:00 AM.
B. Defer landscape installations for new development or require development to install landscaping
that provides a 50 percent reduction in Maximum Applied Water Allowance (MAWA). This would
not apply to sites irrigated with recycled water.
2. Public Outreach Programs:
A. Continue implementation of and possible increase of all public outreach programs listed in previous
stages
B. Issue a press release following Alert Stage declaration
C. Utilize water use allocation software to identify inefficient water users and make direct contact with
these properties.
3. Enforcement Actions (Same as previous stage)
4. Other Administrative Actions:
A. Continue implementation of and possible increase of all other administrative actions listed in prior
stages
B. Prepare utility billing system and bill format for water allocations and reductions listed in subsequent
stages.
C. Establish appeals committee for customers who exceed allotments in subsequent stages, request
health and safety variances, or receive fines from violating water waste prohibitions
D. Increase utility billing training and support to address additional requirements of future stages
E. Begin preparing for Severe Stage
Item 3
Packet Page 60
Draft 2020 Water Shortage Contingency Plan
WSCP-9
Implementation of a Water Demand Offset Program:
At the Alert stage the City may choose to implement a “net neutral” offset program or increase a
previously approved program to a “net positive” program (ex: 1.5:1 or 2:1 offset ratio). Future stages of
the WSCP may suggest a more aggressive, “net positive” water demand offset program.
Water Shortage Response Stage: SEVERE
When the City’s available water supply would provide less than 3.5 years of water, a recommendation
would be made to the City Council to move to the Severe water shortage stage. The City Council would be
recommended to adopt a resolution declaring the City enter the Severe Stage and urge the public to reduce
water use by an additional approximately 10 percent.
At this water shortage response stage, the City would continue implementation of demand reduction
measures, public outreach, and other responses and programs described in prior stages. System and
operational changes would remain in place. At the Severe Stage, a water offset program may increase to
a “net positive” program, such as 1.5:1 or 2:1 ratio.
Previous Water Demand Reduction Programs should be increased to include:
• Limit outdoor watering to three days a week and only between the hours of 7:00 PM and 7:00 AM.
During the Severe, Extreme, and Critical stages of the WSCP the City may adopt a Water Allotment
Program, restricting the water use on an account-by-account basis. The following allotment method may
be used:
Customer Classification Severe Stage Allotment
Single Family Residential and
Multi-family Residential
A per capita allotment allowing for indoor
use and a minimal outdoor irrigation budget.
Verification of persons per household may
be requested
Commercial and Institutional Baseline allocation or allocation based on
percent reduction from normal usage
Landscape Meters Allocation based on percent reduction from
normal usage;

WSCP-10
Water Shortage Response Stage: EXTREME
When the City’s available water supply would provide less than three years of water, a recommendation
would be made to the City Council to move to the Extreme water shortage stage. The City Council would
be recommended to adopt a resolution declaring the City enter the Extreme Stage and urge the public to
reduce water use by an additional 10 percent.
At this water shortage response stage, the City would continue implementation of demand reduction
measures, public outreach, and other responses and programs described in prior stages. System and
operational changes would remain in place. At the Severe Stage, a water offset program may increase to
a “net positive” program, such as 1.5:1 or 2:1 ratio.
Previous Water Demand Reduction Programs should be increased to include:
• Limit outdoor watering to two days a week and only between the hours of 7:00 PM and 7:00 AM.
• Optional implementation of additional restrictions on turf and/or spray irrigation.
Customer Classification Extreme Stage Allotment
Single Family Residential and
Multi-family Residential
A per capita allotment allowing for indoor
use and a reduced outdoor irrigation budget
versus the Severe stage. Verification of
persons per household may be requested
Commercial and Institutional
Reduced baseline allocation or allocation
based on percent reduction from normal
usage
Landscape Meters Reduced allocation based on percent
reduction from normal usage;
At this stage, due to the limited water supplies that remain, the City could consider removal of the “courtesy
notification”.
Water Shortage Response Stage: CRITICAL
When the City’s available water supply would provide less than 2.5 years of water, a recommendation
would be made to the City Council to move to the Critical water shortage stage. The City Council would be
recommended to adopt a resolution declaring the City enter the Critical Stage and urge the public to reduce
water use by an additional approximately 10 percent.
At this water shortage response stage, the City would continue implementation of demand reduction
measures, public outreach, and other responses and programs described in prior stages. System and
operational changes would remain in place. At the Severe Stage, a water offset program may increase to
a “net positive” program, such as 1.5:1 or 2:1 ratio.
Previous Water Demand Reduction Programs should be increased to include:
• Cessation irrigation for all customers, minus specific exemptions.
Customer Classification Critical Stage Allotment
Single Family Residential and
Multi-family Residential
A per capita allotment allowing for indoor
water use. Irrigation not permitted.
Item 3

Verification of persons per household may
be requested
Commercial and Institutional
Reduced baseline allocation or allocation
based on percent reduction from normal
usage. Irrigation not permitted.
Landscape Meters Not Permitted
At this stage, due to the limited water supplies that remain, the City would consider the cessation of new
connections to the City’s water system.
5. WSCP EXEMPTIONS AND APPEALS
As the community was impacted by the 2011-2015 drought and irrigation restrictions were put into place,
community members advocated for certain exemptions related to water use restrictions. The following
series of exemptions will help ensure the health and well-being of the community while not making a
substantial impact on available water supplies.
Sites using Recycled Water for Irrigation
Sites utilizing recycled water are exempt from irrigation restrictions due to their reliance on recycled water
in place of potable water. These sites include major City parks, such as Damon Garcia Park, French Park,
Islay Park, Laguna Lake Park, Laguna Hills Park, De Vaul Park, the Laguna Lake Golf Course, and Laguna
Middle School, as well as many multifamily and commercial properties.
Irrigation Exceptions at Specific Facilities
During the recent drought City staff and community members provided feedback that City parks with
inadequate irrigation allotments could lead to hazardous conditions at recreation and play environments.
To address these concerns, and to provide communal spaces for recreation during times when many
homes allowed landscapes to die, in 2016 the City Council approved an amendment to Chapter 13.07.030
of the Municipal Code, allowing for daily irrigation at designated City facilities during turf renovation, and
three times per week thereafter. This exemption is recommended to be expanded to include schools within
the City’s boundaries as they are used for recreation in a similar manner to City parks. This exemption
would only go into place in stages of the WSCP requiring irrigation restrictions.
Irrigation of Trees
During the 2011-2015 drought, the City heard from many residents who opted to cease irrigation of their
trees in order to reduce their water demand. Unlike turf, shrubs, and other groundcover, trees take a great
amount of time to grow and provide substantial ecological, environmental, practical, and economic value to
the community. An exemption to irrigation restrictions allowing for the use of a hose and shutoff nozzle to
hand water trees will allow the community to preserve this precious multi-benefit resource.
Hospitals, Healthcare Facilities, and other Specific Business Types
Hospitals, healthcare facilities, and other businesses requiring water for the health and safety of at-risk
people may apply for an exemption on a case by case-basis. This exemption may be granted at the
discretion of the Utilities Director or his/her/their designee.
Appeals
Appeals related to water use restrictions within the WSCP and associated penalties may be appealed to
the Utilities Director or his/her/their designee.
6. REVENUE AND EXPENDITURE IMPACTS
During a water shortage, revenues from water sales can be reduced but the City’s operations and
maintenance costs would not reduce accordingly. In fact, during these periods, the City’s operations
budgets can increase due to the implementation of water demand reduction measures, public outreach,
enforcement, groundwater exploration, water quality concerns, and other actions taken by the City during
the crisis. The reduction in revenues resulting from decreased water use may result in the need to raise
water rates during that period.
Item 3
Packet Page 63
Draft 2020 Water Shortage Contingency Plan
WSCP-12
Under the City’s water rate structure, bills are based predominately on customer usage and resulting
demand on the water system.
To minimize the need to raise rates during water shortages, the City has a policy that requires a minimum
reserve of twenty percent of the Water Fund’s operating budget.
City staff provides ongoing tracking of revenues and evaluates the potential impacts associated with
changes in water demand assumptions used in the Water Fund Analysis. The City Council considers the
water rates necessary to provide water service to the community on an annual basis and approves water
rate changes as needed.
In addition to securing water supplies, Water Fund revenue supports ongoing maintenance and operating
programs needed to ensure that the water treatment and delivery systems meet all federal and state water
treatment regulations and are operated and maintained to provide safe and reliable service.
7. MONITORING, REPORTING, AND REFINEMENT PROCEDURES
The City reads water meters monthly to ensure water consumption data is collected for tracking, analysis,
and to meet state reporting requirements. Monitoring and reporting key water use metrics is fundamental
to water supply planning and management. Monitoring is also essential to ensure that the response actions
are achieving their intended water use reduction purposes, or if new actions need to be considered.
Compliance tracking is also necessary for an effective enforcement program.
To evaluate the functionality of the WSCP and ensure strategies are effective, staff will monitor community
response to water demand reduction measures, public outreach, enforcement, and other administrative
actions at each water shortage response stage. This will include review of monthly water consumption data
for each customer class and monitoring associated fiscal and expenditure impacts. Staff will make
recommendations on program refinements to the City Council with water shortage stage progression.
8. CATASTROPHIC WATER SUPPLY INTERRUPTION
The City has an Emergency Response Plan to cover a variety of potential disasters including earthquakes,
floods, wildland fires, etc. The Plan identifies resources available to the City from other agencies or private
companies in the area. Additionally, the City of Morro Bay and the Whale Rock Commission (of which the
City of San Luis Obispo is a member) executed an agreement in June of 2000 which provides for Mutual
Aid between the agencies during disruption of water deliveries or lack of available water supplies. The
agreement provides a general framework for exchanging water between agencies in the event of
emergencies or other water disruptions. The agreement is voluntary based on each agency’s ability to
assist at any point in the future.
In relation to providing water service, the City would utilize electrical portable generators to minimize water
disruptions during an extended power outage. These generators are available to the City at any time.
The City is a member of the Water Agency Response Network (WARN). WARN is a statewide organization
of water agencies and companies that have entered into a mutual aid agreement to assist other water
agencies during emergencies or other water related situations. The agreement provides the framework for
providing assistance and provides a key contact to initiate a multiple agency response to a water emergency
situation.
