WATER SHORTAGE CONTINGENCY PLAN (AMENDED)
LAY DESCRIPTION – CHAPTER 8
WATER SHORTAGE CONTINGENCY PLAN
Chapter 8 (Water Shortage Contingency Plan) of the City’s 2020 Plan discusses and provides the following:
• The City’s Water Shortage Contingency Plan is a detailed approach which presents how the City intends to act, or respond, in the case of an actual water shortage contingency.
• Preparation of the City’s “Annual Water Supply and Demand Assessment” (or Annual Assessment) is discussed. Commencing July 1, 2022, the City is required to submit the Annual Assessment. The Annual Assessment will include a review of the City’s “unconstrained” water demands for the current year and for a potential upcoming single dry year. Unconstrained water demands represent the City’s water demands prior to any “response actions” the City may invoke pursuant to the City’s Water Shortage Contingency Plan.
• The City will manage water supplies to minimize the adverse impacts of water shortages. The City’s plan for water usage during periods of shortage is designed to incorporate six standard water shortage levels corresponding to progressive ranges from up to a 10, 20, 30, 40, and 50 percent shortage, and greater than a 50 percent shortage.
• For each declared water supply shortage level, customers will be required to reduce their consumption by the percentage specified in the corresponding water supply shortage level.
2020 Urban Water Management Plan
City of Manhattan Beach
• For each declared water supply shortage level, the City has established response actions to reduce demand on water supplies and to reduce any shortage gaps in water supplies. These demand reduction actions include irrigation and other outdoor use restrictions, rate structure changes, and other water use prohibitions. • The operational changes the City will consider in addressing water shortages on a short-term basis are discussed and include improved monitoring, analysis, and tracking of customer water usage to enforce demand reduction measures. • The City’s Emergency Response Plan is summarized. The Emergency Response Plan provides the management, procedures, and designated actions the City and its employees will implement during emergency situations ( including catastrophic water shortages) resulting from natural disasters, system failures, and other unforeseen circumstances.
• The preparation of the City’s seismic risk assessment and mitigation plan is discussed. The locations of earthquake faults in the vicinity of the City’s water service area are provided.
• The effectiveness of the shortage response actions for each of the City’s standard water shortage levels is presented. The City has been able to provide sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands.
• The communication protocols implemented by the City when it declares any water shortage level are presented.
• The compliance and enforcement procedures associated with City’ s standard water shortage levels are presented.
• The legal authorities associated with City’s standard water shortage levels are presented.
• The financial consequences associated with City’s standard water shortage levels are presented.
• The City will evaluate the need for revising the Water Shortage Contingency Plan in order to resolve any water shortage gaps, as necessary. The steps necessary

ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES
________________________________________________________________________
CWC 10632.
(a)(2) The procedures used in conducting an annual water supply and demand assessment that include, at a minimum, both of the following:
(A) The written decision-making process that an urban water supplier will use each year to determine its water supply reliability.
(B) The key data inputs and assessment methodology used to evaluate the urban water supplier’s water supply reliability for the current year and one dry year, including all of the following:
(i) Current year unconstrained demand, considering weather, growth, and other influencing factors, such as policies to manage current supplies to meet demand objectives in future years, as applicable.
(ii) Current year available supply, considering hydrological and regulatory conditions in the current year and one dry year. The annual supply and demand assessment may consider more than one dry year solely at the discretion of the urban water supplier.
(iii) Existing infrastructure capabilities and plausible constraints.
(iv) A defined set of locally applicable evaluation criteria that are consistently relied upon for each annual water supply and demand assessment.
(v) A description and quantification of each source of water supply.
CWC 10632.1.
An urban water supplier shall conduct an annual water supply and demand assessment pursuant to subdivision (a) of Section 10632 and, on or before July 1 of each year, submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the supplier’s water shortage contingency plan. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later.
________________________________________________________________________
Commencing July 1, 2022, the City is required to submit an “Annual Water Supply and Demand Assessment” (Annual Assessment) in accordance with DWR’s guidance and requirements. The Annual Assessment will include a review of the Cit y’s unconstrained water demands (i.e. water demands prior to any projected response actions the City may
2020 Urban Water Management Plan
City of Manhattan Beach
trigger under this Water Shortage Contingency Plan) for the current year and the upcoming (potential single dry) year. The City will also include information regarding anticipated shortages, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the Cit y’s Water Shortage Contingency Plan.
For each Annual Assessment, the City plans to prepare a preliminary assessment which evaluates the adequacy of its water supplies for the current and upcoming years by April of each year. The preliminary assessment will include a review of water supplies for at least a single dry year.
The components of Annual Assessment consist of the following:
• A written decision-making process
• Key data inputs and assessment methodology
DECISION MAKING PROCESS
The City pumps and treats groundwater from the West Coast Basin and purchases imported water supplies from WBMWD as its primary source s of water supply.
Consequently, during the third quarter of each fiscal year the City will review its water demands from the initial six months along with the current groundwater basin conditions and local hydrology. This information will be used to help develop the Annual Assessment. A draft of the Annual Assessment will be circulated internally within the City for peer review and comment. Based on comments received, a redraft will be prepared and provided to the City’s Public Works Director during the Spring of each year. The draft will subsequently be provided to the City Manager for final review. Subsequently, a final draft of the Annual Assessment will be provided to the City Council for review and included
2020 Urban Water Management Plan
City of Manhattan Beach
in the agenda as part of a City meeting such that it can be approved and any recommended specific shortage response actions may be enacted. The final Annual Assessment will be provided to DWR no later than July 1 of each year.
The Annual Assessments will be instrumental in providing guidance to the City for decisions regarding potential declarations of a water supply shortage and implementation of water reduction stages, instituting mandatory water restrictions, promoting water use efficiency and conservation programs, water rates and drought rate surcharges, and the necessity of pursuing alternative water supplies. This process will help ensure adequate water supplies resources are available to the City.
DATA METHODOLOGIES
The key data inputs and methodologies which will be evaluated by the City during the preparation of the preliminary assessment will include the following:
1) Evaluation Criteria: The locally applicable evaluation criteria used to prepare the Annual Assessment will be identified. The evaluation criteria will include, but is not limited to, an analysis of current local hydrology (including rainfall and groundwater levels), current water demands, a review of water system improvement plans which may impact infrastructure availability, and water quality regulations which may impact groundwater availability.
2) Water Supply: A description of each available water supply source will be provided.
The descriptions will include a quantification of each available water supply source and will be based on review of current production capacities, historical production, Urban Water Management Plans, and prior water supply studies (including Water Supply Assessments and/or Master Plans).
2020 Urban Water Management Plan
City of Manhattan Beach
3) Unconstrained Water Demand: The potential unconstrained water demands during the current year and the upcoming (potential single dry) year will be reviewed. The review will include factors such as weather, existing and projected land uses and populations, actual customer cons umption and water use factors, monthly Urban Water Supplier Monthly Reports, existing water shortage levels (see Section 8.3), and existing water conservation ordinances (see Section 9.2.1).
4) Planned Water Use for Current Year Considering Dry Subsequent Year: The water supplies available to meet the demands during the current year and the upcoming (potential single dry) year will be considered and identified by each type of supply.
The evaluation will include factors such as estimated water demands, weat her, groundwater basin operating safe yields, water quality results, existing available pumping capacities, imported water allocations, contractual obligations, regulatory issues, use of emergency interconnections, and the costs associated with producing each water supply source.
5) Infrastructure Considerations: The capabilities of the water distribution system infrastructure to meet the water demands during the current year and the upcoming (potential single dry) year will be considered. Available production capacities (e.g. groundwater well capacities) and distribution system water losses (see Section
4.2.4) will be reviewed. In addition, capital improvement and replacement projects, as well as potential projects which may increase water system and product ion capacities (see Section 6.2.8), will be considered.
6) Other Factors: Additional local considerations, if any, which can affect the availability of water supplies will be described.

SIX STANDARD WATER SHORTAGE LEVELS
________________________________________________________________________
CWC 10632.
(a)(3)(A) Six standard water shortage levels corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and greater than 50 percent shortage. Urban water suppliers shall define these shortage levels based on the suppliers’ water supply conditions, including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indicative of the water supply available for use.
Shortage levels shall also apply to catastrophic interruption of water supplies, including, but not limited to, a regional power outage, an earthquake, and other potential emergency events.
(B) An urban water supplier with an existing water shortage contingency plan that uses different water shortage levels may comply with the requirement in subparagraph (A) by developing and including a cross -reference relating its existing categories to the six standard water shortage levels.
________________________________________________________________________
The City will manage water supplies prudently to minimize the adverse impacts of water shortages. The City’s plan for water usage during periods of shortage is designed to incorporate six standard water shortage levels corresponding to progressive ranges from up to 10, 20, 30, 40, and 50 percent shortages and greater than a 50 percent shortage.
The City’s Ordinance No. 15-0008, adopted in 2015, previously established five (5) water shortage levels. A copy of Ordinance No. 15- 0008 is provided in Appendix M. In accordance with the California Water Code in which urban water suppliers are required to define six standard water shortage level, the City has developed the crosswalk illustrated below that translated the City’s previously established shortage levels to the mandated standard shortage levels.

SUPPLY AUGMENTATION
The City does not plan to add a new source of water supply to address customer demands, but instead will consider increased supplies from existing sources. Table 8- 3 reflects this approach and does not identify any new supplies. Instead, the City will focus
2020 Urban Water Management Plan
City of Manhattan Beach
on demand reduction measures in the event existing sources of supply are not sufficient to meet customer demands. As discussed in Chapter 6, the City’s sources of water supply include groundwater produced from the West Coast Basin, imported sur face water purchased from MWD through WBMWD, and recycled water supplies provided by LACSD. As noted in Section 8.2, beginning July 1, 2022, the City will prepare and submit an Annual Assessment which will include a review of water supplies available to meet water demands for the current and upcoming years. If the City is currently in, or considers entering into, one of the standard water shortage levels identified in Section 8.3, the City will consider the water supply (augmentation) actions described below.
For each water shortage level discussed in Section 8.3, the City will increase groundwater production from the West Coast Basin to the extent possible . In addition the City will consider supplementing its existing water supplies through purchase of additional imported water supplies. Due to previous critically dry conditions, MWD developed the “Water Supply Allocation Plan” whereby available supplies are equitably allocated to its member agencies, including WBMWD. The WSAP establishes ten different sh ortage levels and a corresponding drought allocation to each member agency. Based on the shortage level established by MWD, the WSAP provides a reduced drought allocation to a member agency for its Municipal and Industrial (M&I) retail demand. The ratio of MWD water supply drought allocation to local water supply will change based on the WSAP stage. The MWD drought allocation can be used to make Full Service water deliveries at the Tier 1 rate up to a Tier 1 allocation. Any Full Service water delivered in excess of a drought allocation is subject to a penalty rate in addition to the normal rate paid for the water.
In addition to the WSAP, MWD describes supply augmentation actions in its Regional 2020 UWMP, which is incorporated by reference. MWD’s primary first response to any gap between core supplies (from the State Water Project and Colorado River) and demand is to make optimal use of its supply augmentation options, consisting of drawing from flexible supply programs and storage reserves. MWD has devel oped and actively
2020 Urban Water Management Plan
City of Manhattan Beach
manages a portfolio of water supply programs including water transfer, storage, and exchange agreements. MWD pursues voluntary water transfer and exchange programs to help mitigate supply/demand imbalances and provide additional dry -year supply sources. In addition, MWD has developed significant storage capacity in reservoirs, conjunctive use, and other groundwater storage programs totaling approximately 6.0 million AF. Pursuant to MWD’s “Emergency Storage Objective”, updated in 2019, approximately 750,000 AF of total stored water is emergency storage reserved by MWD for use in the event of supply interruptions. Based on MWD’s historical and on-going water supply and storage programs and management practices, the City can potentially continue relying on purchased imported water supplies from MWD through WBMWD for adequate supply augmentation in response to each of the standard water shortage levels identified in Section 8.3.

NOTES: The City will consider increased production from the West Coast Basin using existing facilities to address increased demands.
In addition, the City will consider supplementing its existing water supplies through purchase of additional imported water supplies.
As noted on Table 8-2, the City plans to implement demand reduction measures in the event water supplies from existing sources are not sufficient to meet anticipated demands.
2020 Urban Water Management Plan
City of Manhattan Beach
OPERATIONAL CHANGES
During a water supply shortage situation, the City will manage its water supply resources to provide sufficient water supplies capable of meeting the demands of its customers.
Section 8.4.1 describes the City’s standard water shortage levels and associated demand reduction measures. Section 8.4.2 describes the City’s water supply sources and water supply augmentation actions available. The supply augmentation actions and demand reduction measures, when implemented, may potentially result in short -term operational changes which are necessary to allow the City to utilize all available water supply sources in response to water shortage situations.
As noted in Section 8.2, beginning July 1, 2022, the City will prepare and submit an Annual Assessment which will include a review of the water supplies available to meet water demands for the current and upcoming years. Preparation of the Annual Assessment will assist the City in determining any potential operational changes. In addition, the City’s standard water shortage levels and the associated demand reduction measures, in conjunction with the City’s existing Demand Management Measures (discussed in Chapter 9), will be essential to the City in reducing water demands during any water shortage period. The operational changes the City will consider in addressing non-catastrophic water shortages on a short-term basis include the following:
• Improved monitoring, analysis, and tracking of customer water usage to enforce demand reduction measures
• Optimized production from existing available water supply sources • Potential use of emergency supply sources, including emergency interconnections • Potential blending of water supply resources
• Improved monitoring, maintenance, and repairs to reduce water distribution system losses
2020 Urban Water Management Plan
City of Manhattan Beach
ADDITIONAL MANDATORY RESTRICTIONS
The mandatory restrictions which are implemented by the City to reduce customer demands are discussed in Section 8.4.1. There are no additional mandatory restrictions planned at this time.
EMERGENCY RESPONSE PLAN
Catastrophic water shortages are incorporated in the City’s standard water shortage levels (identifi ed in Section 8.3) and the associated demand reduction measures (described in Section 8.4. 1). In addition to the water supply augmentation actions (Section 8.4. 2) and potential operational changes (Section 8.4.3) which the City may consider in order to continue providing sufficient water supplies, the City will review and implement any necessary steps included in its “Emergency Response Plan”.
As part of the “America’s Water Infrastructure Act of 2018”, community water systems serving a population greater than 3,300 people, including the City, are required to review and update their “Risk and Resilience Assessment” (RRA) and the associated “Emergency Response Plan” (ERP) every five (5) years. However, due to security concerns regarding the submitting of these reports, water systems are required to submit certifications to the United States Environment Protection Agency (USEPA), from March 31, 2020 and December 30, 2021, confirming the current RRA and ERP have been reviewed and updated.
The City’s RRA, prepared in June 2021, evaluates the vulnerabilities, threats, and consequences from potential hazards to the City’s water system. The City prepared its RRA (which is incorporated by reference) by evaluating the following items:
• Natural hazards and malevolent acts (i.e., all hazards);
2020 Urban Water Management Plan
City of Manhattan Beach
• Resilience of water facility infrastructure (including pipes, physical barriers, water sources and collection, treatment, storage and distribution facilities, and electronic, computer and other automated systems);
• Monitoring practices;
• Financial systems (e.g., billing systems);
• Chemical storage and handling; and
• Operation and maintenance.
The City’s RRA evaluated a series of potential malevolent acts, natural hazards, and other threats in order to est imate the potential “monetized risks” (i.e. associated economic consequences to both the water system and surrounding region, and the likelihood of occurrence) associated with the City’s water facility assets. The cost -effectiveness of implementing potential countermeasures to reduce risks was also reviewed.
The City’s ERP, which is currently being prepared and will be completed in 202 1, will provide the management, procedures, and designated actions the City and its employees will implement during emergency situations (including catastrophic water shortages) resulting from natural disasters, system failures and other unforeseen circumstances. The City’s ERP (which is incorporated by reference) will provide the guidelines for evaluating an emergency situation, procedures for activating an emergency response, and details of the different response phases in order to ensure that customers receive a reliable and adequate supply of potable water. The scope of the ERP includes emergencies which directly affect the water system and the ability to maintain safe operations (such as a chlorine release, and earthquake or a threat of contamination). The ERP will also incorporate the results of City’s RRA and includes the following:
• Strategies and resources to improve resilience, including physical and cybersecurity
• Plans and procedures for responding to a natural hazard or malevolent act
2020 Urban Water Management Plan
City of Manhattan Beach
• Actions and equipment to lessen the impact of a natural hazard or malevolent act • Strategies to detect natural hazards or malevolent act
The City will review the ERP for procedures regarding the utilization of alternative water supply sources in response to water supply shortages, including during the standard water shortage levels. The City will also review applicable procedures descr ibed in the ERP regarding any necessary temporary shutdown of water supply facilities, including appropriate regulatory and public notifications.
SEISMIC RISK ASSESSMENT AND MITIGATION PLAN
________________________________________________________________________
CWC 10632.5.
(a) In addition to the requirements of paragraph (3) of subdivision (a) of Section 10632, beginning January 1, 2020, the plan shall include a seismic risk assessment and mitigation plan to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities.
(b) An urban water supplier shall update the seismic risk assessment and mitigation plan when updating its urban water management plan as required by Section 10621.
(c) An urban water supplier may comply with this section by submitting, pursuant to Section 10644, a copy of the most recent adopted local hazard mitigation plan or multihazard mitigation plan under the federal Disaster Mitigation Act of 2000 (Public Law 106- 390) if the local hazard mitigation plan or multihazard mitigation plan addresses seismic risk. ________________________________________________________________________
The City prepared a “Local Hazards Mitigation Plan” which was approved by the Federal Emergency Management Agency (FEMA) in 2017. The Hazard Mitigation Plan identifies effective ways to assess the significant natural hazards (including earthquakes) that may affect the City and its residents. The Hazard Mitigation Plan provides resources, information, and strategies to reduce the City’s vulnerability to these hazards, while providing guidance for the coordination of mitigation activities throughout the City . The Hazard Mitigation Plan includes mitigation projects necessary to reduce seismic risk to the City’s water distribution system facilities (including its distribution system pipelines,
2020 Urban Water Management Plan
City of Manhattan Beach
groundwater wells, booster pumps, and storage reservoirs) and potential disruptions in providing water service. The City’s Hazard Mitigation Plan is provided in Appendix N.
The County of Los Angeles prepared a “All -Hazards Mitigation Plan” in 2019 which identified methods to assess significant natural hazards (including earthquakes) affecting areas throughout Los Angeles County, and the mitigation strategies necessary to reduce risks, including seismic risk. The County’s All -Hazards Mitigation Plan is provided in Appendix O.
The California Geological Survey has published the locations of numerous faults which have been mapped in the Southern California region. Although the San Andreas fault is the most recognized and is capable of producing an earthquake with a magnitude greater than 8 on the Richter scale, some of the lesser -known faults have the potential to cause significant damage. The locations of these earthquake faults in the vicinity of the City’s water service area are provided in the figure below. The faults that are located in close proximity to and could potentially cause significant shaking in the City’s water service area include the San Andreas fault, the Charnock fault, the Newport-Inglewood fault, the Palos Verdes fault, and the Santa Monica Fault.

The following figure provides the relative intensity of ground shaking in the vicinity of the City’s service area from anticipated future earthquakes. The locations of relatively long - period (1.0 second) earthquake shaking, including the City’s service area, are provided.
Long-period shaking affects tall, relatively flexible buildings, but also correlates with earthquake damage. The shaking potential is calculated based on the level of ground motion that has a 2 percent chance of being exceeded in 50 years (or the level of ground- shaking with an approximate 2,500- year average repeat time). As discussed in Section
8.4.5, the City is currently preparing an Emergency Response Plan which will provide the management, procedures, and designated actions the City and its employees will implement during emergency situations resulting from natural disasters, including during earthquakes, to ensure that customers receive a reliable and adequate supply of potable water. The City’s ERP is incorporated by reference.

SHORTAGE RESPONSE ACTION EFFECTIVENESS
The effectiveness of the shortage response actions for each of the standard water shortage levels identified in Section 8.3 is evident in the City’s historical ability to meet its customer’s water demands in response to a water supply shortage. In addition, the City imposes water consumption regulations and restrictions, and supports local agencies in efforts to enforce regulations and prohibitions on water use. The effectiveness of each of the City’s shortage response actions, in order to reduce any potential gaps between City’s Service Area
2020 Urban Water Management Plan
City of Manhattan Beach
supply and demand, has been quantified in the expected demand reduction provided in Table 8-2 and Table 8-3.
Section 6.1 provides a tabulation of the City’s historical annual water demands for each water supply source. Dur ing the past 10 years, the City experienced a five consecutive year drought within its service area from CY 2011 to CY 2015. Throughout this extended dry year period, the City’s annual water production ranged from 4,878 AF to 5, 924 AF, with an average of approximately 5,595 AF. In addition, historical records indicate the City previously produced a maximum of up to 5,924 AF during CY 2012. The City has been able to provide sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years, including during the summer months.
The City’s water demands during the most recent five years (from CY 2016 to CY 2020) averaged approximately 5,021 AFY. Due to conservation efforts and demand management measures (discussed in Chapter 9), the City’s recent water demands have been significantly less than its historical water dem ands, including during long -term droughts. The City’s projected water demands (during normal, single dry, and multiple dry years) are provided in Section 7.2.3 and are anticipated to incorporate similar reductions in water use rates as a result of the shortage response actions, ongoing conservation efforts, and demand management measures. Because the City’s projected water demands are less than its historical water demands, it is anticipated the City will be able to continue providing sufficient water supplies to its customers to meet projected water demands, including during long-term droughts. In addition, as discussed in Section
8.4.2, based on historical and on- going management practices, the City will be able to continue relying on its water supply source from West Coast Basin for adequate supply augmentation in response to each of the standard water shortage levels identified in Section 8.3.
2020 Urban Water Management Plan
City of Manhattan Beach
Based on the City’s ability in meeting water demands during past water supply shortages, adopted water shortage levels, adjusted operating safe yields, and long-term droughts, it is anticipated that the City will be able to continue providing sufficient water supplies to its customers during any of its standard water shortage levels. Although adequate supplies are anticipated, the cost of those water supplies may become incrementally more expensive. The City will enact varying levels of its water shortage contingency plan to encourage retail customers to reduce water consumption and at the same time reduce the need to use the more expensive water supplies. Notwithstanding, the effectiveness of each of the City’s shortage response actions, in order to reduce any potential gaps between supply and demand, has been quantified in the expected demand reduction provided in Table 8-2 and Table 8-3. The effectiveness of the City ’s shortage response actions is based on the City’s water demands prior to 2015 (unconstrained demands).
The City reduced its water demands in 2015 in response to the Governor’s April 1, 2015 Executive Order B-29-15 which mandated statewide reduction in water use of 25 percent.
The City’s actual water demand reduction during this period was used to estimate the extent of water use reductions for the City’s Water Shortage Levels . The City’s Water Shortage Levels 1, 2, 3, 4, 5, and 6 are expected to reduce water demands by up to 10%, 20%, 30%, 40%, 50%, and greater than 50%, respectively.

The City takes several steps to monitor water consumption during various stages of water supply shortage. The reduction monitoring procedure is described below.
2020 Urban Water Management Plan
City of Manhattan Beach
1. Water Supply Report
Potable water production figures are recorded daily. Totals are reported monthly to the City’s Water Distribution Supervisor are incorporated into a Water Supply Report. This report is then forwarded to the WBMWD and the WRD. With this data it is possible to develop trends for monthly water production and use.
2. Water Usage Records
The City maintains water use records on each individual customer account.
Exceptionally high usage is identified at the time the meter is read. These accounts are investigated for potential water loss or abuse. Additionally, water use graphical trends are recorded on a customer’s water bill, comparing water use for the current billing cycle to the same billing cycle of the previous year.
3. Monthly Water Production Report
During all stages of a water shortage, daily production figures are reported to and monitored by the City’s Water Distribution Supervisor. The Water Distribution Supervisor compares the monthly production to the target monthly production to verify that the reduction goal is being met.

and demands. The City will evaluate the need for revisi ng the Water Shortage Contingency Plan in order to resolve any shortage gaps, as necessary. The City will consider the following potential revisions in the event of a potential shortage gap:
• Implementation of additional public outreach, education, and com munication programs (in addition to the programs discussed in Chapter 9). • Implementation of more stringent water use restrictions under the standard water shortage levels (discussed in Section 8.4.1)
• Implementation of stricter enforcement actions and penalties (discussed in Section
8.6)
• Improvements to the water supply augmentation responses (discussed in Section
8.4.2), as well as any associated operational changes (discussed in Section 8.4.3) which may be required
• Incorporation of additional actions recommended by City staff or other interested parties
The City will use the monitoring and reporting data to evaluate the ability for these potential revisions to resolve any shortage gaps which may occur within the standard water shortage levels.
This Water Shortage Contingency Plan is adopted as part of the City’s 2020 Urban Water Management Plan adoption process discussed in Section 10.3. It is anticipated the City will review, revise, and adopt an updated Water S hortage Contingency Plan as part of preparing its 2025 Urban Water Management Plan as necessary. However, the City will continue to review the monitoring and reporting data, and if needed, update the Water Shortage Contingency Plan more frequently. Any updates to the City’s Water Shortage Contingency Plan will include a public hearing and adoption process by the City Council (see Section 8.12).

SPECIAL WATER FEATURE DISTINCTION
_______________________________________________________________________
CWC 10632.
(b) For purposes of developing the water shortage contingency plan pursuant to subdivision (a), an urban water supplier shall analyze and define water features that are artificially supplied with water, including ponds, lakes, waterfalls, and fountains, separately from swimming pools and spas, as defined in subdivision (a) of Section 115921 of the Health and Safety Code.
________________________________________________________________________
The City’s Water Shortage Contingency Plan defines “decorative water features” as water features which are artificially supplied with water, including ponds, lakes, waterfalls, and fountains, but excluding pools and spas. In general, there are additional health and safety considerations in the water supplied to pools and spas compared to decorative water features. As a result, the City’s Water Shortage Contingency Plan has reviewed the response actions, enforcement actions, and monitoring and reporting programs separately for decorative water features and for pools and spas, as applicable. Under the City’s Municipal Code 7.44.020, no person shall fill any water feature unless the water feature is constructed with a water recirculation system or fill any water recreation facility.
