SHORTAGE CONTINGENCY PLAN AND WATER
CONSERVATION REGULATIONS, ADDING THE
PROGRAM TO THE ADMINISTRATIVE CODE, AND
RESCINDING ORDINANCE 2015-01
WHEREAS, the San Dieguito Water District ("District") is a California irrigation district
organized and operating according to California law; and
WHEREAS, periodic droughts are a historic fact in the State of California; and
WHEREAS,the District derives a portion of the water that it delivers to its customers from
waters imported from outside District boundaries; and
WHEREAS, the quality and quantity of imported water is under the control of other
agencies, and may be subject to conditions beyond the control of those other agencies or the
District; and
WHEREAS, California Constitution Article X, section 2 and California Water Code
section 100 provide that because of conditions prevailing in the state of California("State"), it is
the declared policy of the State that the general welfare requires that the water resources of the
State shall be put to beneficial use to the fullest extent of which they are capable, the waste or
unreasonable use of water shall be prevented,and the conservation of such waters is to be exercised
with a view to the reasonable and beneficial use thereof in the interest of the people and the public
welfare; and
WHEREAS,pursuant to California Water Code section 106, it is the declared policy of the
State that the use of water for domestic use is the highest use of water and that the next highest use
is for irrigation; and
WHEREAS,pursuant to California Water Code section 375-378,the District is authorized
to adopt and enforce a water conservation program to reduce the quantity of water used by persons
within its jurisdiction for the purpose of conserving the water supplies of the District; and
WHEREAS, California, including San Diego County, experienced significant dry year
conditions in 2012-2017, which led local water agencies to declare water shortage conditions that
triggered drought actions; and
WHEREAS, beginning on January 17, 2014, with the Governor Brown proclaimed
condition of statewide drought, the District experienced a direct impact on the reliability of
available water supplies.The District's reliability was increased through customer curtailment due
to demand management measures implemented; and
WHEREAS, following the end of the statewide drought conditions, the California
Legislature amended the Urban Water Management Planning Act in 2018 to include additional
water shortage planning requirements. Water Code Section 10632 now mandates the adoption of
Water Shortage Contingency Plans ("WSCP") with prescribed elements, and the District must
describe in its WSCP the legal authorities that empower the District to enforce shortage response
actions identified in its WSCP; and
WHEREAS, because of the prevailing conditions in the State and the declared policy of
the State, the District hereby finds and determines that it is necessary and appropriate for the
District to amend, adopt, implement, and enforce a water conservation program to reduce the
quantity of water used by consumers within the District to ensure that there is sufficient water for
human consumption, sanitation, and fire protection and to ensure the District can implement and
enforce the shortage response actions specified in its WSCP; and
WHEREAS, pursuant to California Water Code section 350, the Board of Directors is
authorized to declare a water shortage emergency to prevail within its jurisdiction when it finds
and determines that the District will not be able to or cannot satisfy the ordinary demands and
requirements of water consumers without depleting the water supply of the District to the extent
that there would be insufficient water for human consumption, sanitation,and fire protection,and
as more fully set forth in this chapter, based upon the occurrence of one or more of the following
conditions or circumstances:
A. A general water supply shortage due to increased demand and/or limited supplies.
B. Distribution or storage facilities of the District, or any agency supplying water to the
District, become inadequate or are restricted.
C. A major failure of the supply, storage, and/or distribution facilities of the District or any
agency supplying water to the District.
D. Contamination of the water supply, storage, and/or distribution facilities of the District or
any agency supplying water to the District.
E. Act of nature which in the opinion of the District constitute an emergency situation or
which require special water conservation actions.
WHEREAS, in the event the District determines that it is necessary to declare that a water
shortage emergency exists, this Ordinance authorizes the District to implement certain shortage
response measures and a water conservation and regulatory program to regulate water
consumption activities within the District and ensure that the water delivered in the District is put
to beneficial use for the greatest public benefit, with particular regard to domestic use, including
human consumption,sanitation,and fire protection,and that the waste or unreasonable use of water
is prevented; and
WHEREAS, the District is authorized to prescribe and define by ordinance restrictions,
prohibitions,and exclusions for the use of water during a threatened or existing water shortage and
adopt and enforce a water conservation and regulatory program to:(i)prohibit the waste of District
water or the use of District water during such period;(ii)prohibit use of water during such periods
for specific uses that the District may from time to time find nonessential; and (iii) reduce and
restrict the quantity of water used by those persons within the District for the purpose of conserving
the water supplies of the District; and
WHEREAS,the District hereby finds and determines that the District shall: (i) implement
water conservation and water shortage response measures; (ii) regulate the water consumption
activities of persons within the District for the purposes of conserving and protecting the District's
water supplies, reducing the quantity of water consumed, and deterring and preventing the waste
or unreasonable use or unreasonable method of use of valuable water resources; and(iii)establish
and collect regulatory fees and impose administrative penalties as set forth herein to accomplish
these purposes and/or recover the costs of the District's water conservation and regulatory
program; and
WHEREAS,the District hereby finds and determines that it is desirable to codify the rules
and regulations governing its actions,and the actions of persons using and consuming water within
the District, particularly during declared water shortages and water shortage emergencies, to
protect the general welfare and the District's water supplies, and to reduce water consumption in
accordance with the declared policies and laws of the State;and
WHEREAS,the District desires to adopt a Water Shortage Response Program in the form
attached hereto as Exhibit A, and by this reference, incorporated herein, and thereby desires to
establish standards and procedures to enable implementation and enforcement of local water
shortage contingency measures.These measures align with the California Water Code Section 353
which specifies that"when the governing body has so determined and declared the existence of an
emergency condition of water shortage within its service area, it shall thereupon adopt such
regulations and restrictions on the delivery of water and the consumption within said area of water
supplied for public use as will in the sound discretion of such governing body conserve the water
supply for the greatest public benefit with particular regard to domestic use, sanitation, and fire
protection."
NOW THEREFORE, it is hereby ordained by the Board of Directors of the San Dieguito
Water District as follows:
Section 1. Ordinance No. 2015-1 is hereby rescinded and replaced with this
Ordinance.
Section 2. The District hereby adopts the Water Supply Shortage Response Program
in the form attached hereto as Exhibit A, and by this reference, such Water Supply Shortage
Response Program is incorporated as if fully set forth herein. This Ordinance, including the Water
Supply Shortage Response Program attached hereto and incorporated herein, shall serve as the
District's Water Shortage Contingency Plan and as the District's Water Conservation Ordinance
in accordance with section 375 et seq. of the California Water Code.
Section 3. Article 30 of the District's Administrative Code is hereby amended in its
entirety and replaced with the attached Water Supply Shortage Response Program in the form
attached hereto as Exhibit A.
Section 4. The adoption of this Ordinance is not subject to the requirements of CEQA,
or alternative, is exempt from CEQA. As only water conservation would result from the
implementation of the Ordinance's provisions,the Ordinance would not commit the District to any
action that would result in any significant environmental effects. As a result, per State CEQA
Guidelines §15378,the Ordinance does not constitute a project subject to requirements of CEQA.
Alternatively,the adoption of this Ordinance is exempt from CEQA under State CEQA Guidelines,
§15061 (b)(3) and §15308 because CEQA only applies to projects that have the potential for
causing a significant effect on the environment and it can be seen with certainty that there is no
possibility that the Ordinance will have a significant effect on the environment, and because the
Ordinance would result in the conservation of water, a limited and currently scare resource, and
would, therefore, have a beneficial effect on the environment. On this basis, and the on the basis
of the information contained in the whole of the administrative record, the adoption of this
Ordinance requires no further analysis under CEQA.
Section 5. If any provision of this Ordinance or the application thereof to any person
or circumstance is held invalid, such invalidity shall not affect other provisions or applications of
the Ordinance which can be given effect without invalid provision or application, and to this end
the provisions of this ordinance are severable. The Board hereby declares that it would have
adopted this Ordinance irrespective of the invalidity of any particular portion thereof.
Section 6. This Ordinance shall become effective immediately upon adoption.
PASSED AND ADOPTED at a meeting of the Board of Directors of San Dieguito Water
District held on the 191 day of May, 2021.

Water Shortage Contingency Plan
Article 30 Water Supply Shortage Response Program
This Water Supply Shortage Response Program serves as the San Dieguito Water District's
(District) Water Shortage Contingency Plan(WSCP).
CWC 10632
(a)Every urban water supplier shall prepare and adopt a water shortage contingency plan as part of
its urban water management plan...
(c) The urban water supplier shall make available the water shortage contingency plan prepared
pursuant to this article to its customers and any city of county with which it provides water supplies no
later than 30 days after adoption of the water shortage contingency plan.
The Urban Water Management Planning Act (UWMP Act), enacted in 1983, requires water
suppliers to conduct shortage contingency planning analyses that outline specific actions a supplier
will take in response to short-term water supply shortages caused by droughts and/or catastrophic
supply interruptions. Droughts have increased in frequency and severity throughout Southem
California over the past few decades, triggering the District to implement water conservation
measures to achieve demand reductions in order to meet available supplies. The District has
experienced three droughts over the past few decades— one in the 1990s, one in the late 2000s,
and the most recent one that occurred between 2014 and 2017—where supply deficiencies were
significant enough to necessitate mandatory water use restrictions. In the 1990s, a statewide
drought halted operation of the State Water Project (SWP) and, simultaneously, a local drought
significantly reduced flows into Lake Hodges. At that time, SDCWA informed its member
agencies that a mandatory 20%reduction in demand was needed.
Between 2007 — 2011, mandatory water use restrictions implemented in response to another
statewide drought,combined with litigation that impacted operation of the SWP in the Bay-Delta,
substantially reduced pumping volumes from the SWP. In April 2007, MWD notified its member
agencies (including the SDCWA) that it expected to face challenges in meeting demands due to
insufficient imported water supplies from the SWP and the Colorado River Aqueduct (CWA).
MWD, the SDCWA, and the District all adopted voluntary and mandatory water use restrictions
as dry conditions persisted into 2009. In April 2009, MWD's Board of Directors voted to allocate
urban water deliveries to its member agencies in FY 2010 for the first time in decades. In turn,the
SDCWA allocated water deliveries to its member agencies. The SDCWA's long-term strategy to
improve water supply reliability by diversifying the region's water supply portfolio helped offset
some of the required cutbacks from MWD. Residences and businesses responded to the call for
conservation and urban water use dropped throughout San Diego County. Although hydrologic
conditions began to improve in 2010, storage reserves remained low, and allocations continued
into FY 2011 to help restore storage reserves and prepare for a potential dry water year.
In response to the most recent severe drought that occurred between 2012 and 2017, water
suppliers implemented the strictest water use restrictions to date through activation of drought
response levels. Drought response levels are enacted to reduce a supplier's total urban water use
through encouragement and enforcement of several voluntary and mandatory shortage response
actions to achieve a specified reduction. The District defines and activates its drought response
levels in accordance with drought response levels defined and activated by the SDCWA. The
SDCWA's Water Shortage and Drought Response Plan defines its drought response levels,which
can be activated by its Board of Directors as needed to reduce water use in response to drought
Draft Page 30-1
San Dieguito Water District
Water Shortage Contingency Plan
conditions. Upon being activated, the Board of Directors will set forth a drought level for the
SDCWA, and the SDCWA will encourage its member agencies to adopt similar drought levels.
The District has responded to drought conditions by adopting a drought management plan,
implementing mandatory and voluntary water use restrictions, and implementing new water
conservation programs. The District's drought management plan is currently incorporated in the
District's Administrative Code as Article 29 (Water Supply Shortage Response Program)and will
be updated and replaced by Article 30. This Water Supply Shortage Response Program, also
known as the District's Water Shortage Contingency Plan (WSCP), establishes regulations on
water management by the District and progressive restrictions on water use to be implemented for
responding to water supply limitations resulting from declared water shortages or declared water
shortage emergencies.
In April 2015,the Govemor of California issued an executive order declaring a State of Emergency
requiring the California State Water Resources Control Board (State Board) to implement
regulations and restrictions to achieve a 25% reduction in potable water use statewide, though
individual agencies were required to achieve varying reductions based on existing per capita water
use. To address this executive order, the State Board then amended its emergency drought
regulations requiring the District to reduce its water use by 28% compared to its 2013 water use.
In response to these state actions,the District revised its Water Supply Shortage Response Program
(Article 29) in April 2015 to enforce a water allocation program to reduce the District's overall
water use to meet the State requirements. Additional revisions included water waste prohibitions
and the establishment of penalties for violation of implemented water allocations during Level 3
and Level 4 drought conditions.
In response to the drought, the District activated Water Shortage Response Level 2 in June 2014
and increased to a Water Shortage Response Level 3 in May 2015,increasing water use restrictions
and prohibitions. The District began to relax water use restrictions as supplies began to recover
and drought conditions improved. In April 2016, the District went from a Water Shortage
Response Level 3 to a Level 2.Three months later, in July 2016,the District further relaxed water
use restrictions and declared a Level 1 Shortage, which encourages but does not mandate water
use restrictions. In April 2017, the Governor of California issued an executive order lifting the
drought emergency water restrictions in San Diego County and the District followed by ending its
Level 1 restrictions.
The District will update its Water Supply Shortage Response Program (Article 29 to new Article
30) again in May 2021 to comply with new 2018 legislation that was adopted in response to the
recent severe drought. Pursuant to the 2018 legislation, water suppliers must address several new
requirements with prescriptive elements in their water shortage contingency plans, including, but
not limited to:
• Describe key attributes of and procedures for conducting an annual water supply reliability
assessment;
• Update to six standard water shortage response levels (progressive ranges of 10%, 20%,
30%,40%, 50•/u, and greater than 50%shortage);
• Quantify estimated water savings associated with each shortage response action;
• Describe communication protocols and public outreach measures;
Draft Page 30-2
San Dieguito Water District
Water Shortage Contingency Plan
• Identify monitoring and reporting procedures to track compliance;and
• Discuss methods to reevaluate and improve the water shortage contingency plan.
This WSCP contains a detailed discussion of the water shortage contingency planning undertaken
by the District to prepare for,and implement during,a drought or another catastrophic interruption
of water supplies. The WSCP also describes the District's annual water supply reliability
assessment procedures and addresses the District's mandatory prohibitions and penalties
associated with excess water use.
CWC 10644(a)(2)
The plan,oramendments to the plan,submitted to the department..shall include any standardized forms,
tables, or displays specified by the department.
It should be noted that DWR requires water suppliers to use their standardized submittal tables
within this WSCP. Some of the tables provided in this WSCP have titles that are designated by
DWR to ensure compliance with Water Code section 10644(a)(2).
30.1 Water Supply Reliability Analysis
CWC 10632(a)(1)
The analysis of water supply reliability conducted pursuant to Section 10635.
The District conducted a water supply reliability analysis in its 2020 Urban Water Management
Plan for three scenarios for the planning period of 2025—2045. The scenarios evaluated included
a normal year, a single dry-year, and five consecutive dry years (multiple dry-year scenario).
Because the District relies on the San Diego County Water Authority(SDC WA)to meet demands
that cannot be met using local supplies (e.g., Lake Hodges, non-potable recycled water), the
District's reliability analysis as described in its 2020 UWMP tiers off of SDCWA's reliability
analysis included in the San Diego County Water Authority2020 Urban Water Management Plan.
SDCWA's modeling found that demands across the region are projected to increase between 7%
and 9% over normal year conditions in the single dry-year and multiple dry-year scenarios
evaluated for 2025-2045. The District's reliability analysis assumes that changes in regional
demand stemming from dry conditions would be experienced at similar rates at the local level
because dry conditions would generally be experienced across the entire region. Supply
availability during dry conditions varies depending on the type of supply being considered. In
SDCWA's analysis, groundwater and recycled water supplies are considered reliable under all
scenarios,while availability of surface water supplies,including the District's Lake Hodges,would
decrease in the single and multiple dry-year scenarios. As demand increases under dry conditions
and local supply availability decreases, member agency purchases from SDCWA would increase.
SDCWA's analysis found that there would be sufficient supplies available through local and
imported sources,or from storage,to meet demands across all of its member agencies in all years
of each scenario.As such,the District anticipates 100%reliability under all scenarios as evaluated
in the 2020 UWMP.
In addition to the water supply reliability analysis that considered normal, single dry-year, and
multiple dry-year scenarios over the 2025-2045 planning period, the District's 2020 UWMP
included a Drought Risk Assessment (DRA) for the next five years (2021-2025). As with the
supply reliability analysis,the District tiered off of SDCWA's DRA(included in San Diego County
Draft Page 30-3
San Dieguito Water District
Water Shortage Contingency Plan
Water Authority 2020 Urban Water Management Plan), because the District would increase
purchases from SDCWA to meet local demands that cannot be met with Lake Hodges or recycled
water. The DRA analysis projected demand increases between 8%and 25%over 2020 demands,
based on the five driest consecutive years on record, which were 2014-2018.
30.2 Annual Water Supply and Demand Assessment Procedures
CWC 10632.1
An urban water supplier shall conduct an annual water supply and demand assessment pursuant to
subdivision(a)ofSecdon 10632and,on or before July I ofeachyear,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 watershortage conungencyplan.An urban watersupplier that relies on imported waterfrom
the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand
assessment within 14 days ofreceivingits final allocation, orbyJulyl ofeachyear, whicheveris later.
CWC 10632(a)(2)
The procedures used in conducting an annual water supply and demand assessment that include, at
minimum, both of the following:
(A) The written decision makingprocess 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
reliability for the current year and one dry year, including all of the following:
(B)(i)Currentyear unconstrained demand, considering weather,growth,and otheriniluencingfactors,
such as policies to manage current supplies to meet demand objectives in future years,as applicable.
(B)(ii)Cunentyearavailable supply,considering hydrological and regulatory conditions in the current
yearand one dryyear. The annual supplyand demand assessment may considermore than one dryyear
solely at the discretion of the urban water supplier.
(B)(ld)Existinginfrastructure capabilities and plausible constraints.
(B)(iv)A defined set of locally applicable evaluation criteria that are consistentlyrelied upon for each
annual water supply and demand assessment.
(B)(v)A description and quantification of each source of water supply.
Beginning in 2022,pursuant to the new requirements discussed in CWC 10632.1,water suppliers
will be required to submit a water supply and demand assessment report(Annual Assessment) to
DWR on or before July 1 st of each year. The Annual Assessment will be used to evaluate short-
term water supply reliability for the upcoming fiscal year and will discuss the District's existing
and projected water supply sources (including imported water from SDCWA), unconstrained
customer demand,planned water use for the current year assuming that the following year will be
dry, infrastructure capabilities and constraints, and any other local factors that may influence or
disrupt water supplies. Because the District purchases water from the SDCWA, the Annual
Assessment will be conducted in coordination with the SDCWA's annual assessment. As
described in SDCWA's San Diego County Water Authority 2020 Urban Water Management Plan,
SDCWA's annual assessment will consider municipal and industrial supplies and projected
demands, which includes a wide range of uses, including residential demand as well as
commercial, industrial, and institutional use. SDCWA's short-term forecast model considers
Draft Page 30-4
r
San Dieguito Water District
Water Shortage Contingency Plan
historic water demand patterns, weather, local economic index, and anticipated conservation
levels, as well as member agency local supplies that may be affected by weather or other factors.
The District will perform its water supply and demand assessment annually in spring each year to
assess short-term reliability for the upcoming fiscal year. Results of the annual analysis will be
discussed in a report and presented to the District's Board in June.If the analysis projects a supply
deficit, the Board will vote to determine the appropriate shortage response level and associated
actions necessary to reduce demand to ensure adequate supply.Because the District will coordinate
its Annual Assessment with SDCWA's annual assessment, the timeline for conducting the
District's Annual Assessment is based on the SDCWA's timeline. The District's timeline for
developing its Annual Assessment is presented in Table 30-1.

30.3 Six Standard Water Shortage Levels and Shortage Response
Actions
CWC 10632(a)
Every urban water supplier shall prepare and adopt a water shortage contingency plan as part of its
urban water management plan that consists of each of the following elements:
(3)(A)Sir 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 percemage 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.
(3)(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 District's WSCP is currently incorporated into its Water Supply Shortage Response Program
(Article 29) and will be replaced with this WSCP (Article 30) to comply with state regulations.
The WSCP is designed to establish priorities and restrictions during various types of water
shortages, including 10% to greater than 50% reductions in water supply. The WSCP specifies
watering restrictions for outdoor irrigation (including golf course, park, school, agriculture, and
commercial uses), mobile equipment washing, pool refilling, over-irrigation, and hardscape
maintenance.
The District's WSCP establishes levels of water supply shortage response actions to be
implemented in times of anticipated shortages.As discussed in the preceding section,the District
sets its drought response levels in accordance with drought response levels determined by the
SDCWA and defined in SDCWA's Water Shortage and Drought Response Plan. The District has
developed this WSCP to update its shortage response levels from four to six stages of action to
align its plan with the SDCWA's levels and to comply with CWC 10632(a)(3)(A). The District
will recommend that the District Board adopt this Plan in May 2021.
Upon activation of SDCWA's drought response levels, its Board of Directors will set forth a
drought level, and the SDCWA will encourage its member agencies to adopt similar drought
levels.The District's six stages of actions(Levels l —6),as shown in Table 30-2,are a sequential,
regulatory program of increasingly stringent water use restrictions. When the District declares that
a particular shortage level is in effect, District customers must comply with all regulations
contained in the declared stage or face a potential penalty.

water services and new temporary and permanent meters unless the District
provides a program to offset new water demands equal to the new use. The
District may also establish a water allocation policy for properties served and
suspend considerations of annexations to its service area.

The District will compare its projected local and imported water supplies against its projected
water demands. If the District's water supply and demand assessment anticipates that available
supplies will be less than projected demands, it will then determine the percentage reduction in
demands that is required to offset water supply shortages. The District will trigger the appropriate
shortage response stage to achieve the required demand reductions, in conjunction with the
SDCWA and MWD.
The demand reduction actions associated with each of the District's six shortage levels are
described in more detail in Section 30.2.1.
30.2.1 Shortage Response Actions
CWC 1063z(a)(4)
Shortage response actions that align with the defined shortage kvels and hidude, at a minimum,all of

CWC 10632(b)
For purposes of developmg the water shortage contingency plan pursuant to subdivision(a), an urban
water supplier shall analy2e 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.
Health and Safety Code Section 115921
As used in this article the following terms have the following meanings:
(a) "Swimming pool"or "pool"means any structure intended for swimming or recreational bathing
that contains water over 18 inches deep. "Swimming pool" includes in ground and aboveground
structures and includes, but is not limited to, hot tutu, spas,portable spas, and non-portable wading
pools.
Voluntary or mandatory water use restrictions and prohibitions to be implemented for each stage
are discussed below and listed in Table 30-3.
Water Shortaae Response Level 1 (10% Reduction)
Level 1 may apply when there is a reasonable probability that there will be water supply shortages
and that a consumer demand reduction of up to 10% is required. At this stage restrictions are
voluntary, and the District would increase its public education and outreach efforts to encourage
customers to take actions to conserve water. A Level 1 condition is declared by the General
Manager upon a written determination of the existence of the facts and circumstances supporting
the determination. Some voluntary measures under Level 1 include stop hosing down paved

30.4 Water Shortage Emergency Response
The District has taken significant steps to ensure it is prepared for catastrophic water supply
interruption, including implementing local measures to increase supply reliability, developing
planning documents that outline contingency actions,and coordinating with the SDC WA and other
member agencies.
Local Supply Reliability Measures
In addition to water demand reductions that would be implemented during a catastrophic supply
interruption, the District maintains partial ownership of the Badger Plant and access to substantial
raw water reserves. The District also has access to potable water SDCWA connection and
numerous emergency interconnections with OMWD. The District installed an additional
emergency interconnection with OWMD at Manchester Avenue in 2013 to ensure sufficient water
for fire protection and to add redundancy to the District's water system. Construction of a parallel
54-inch transmission supply pipeline from the R.E. Badger Filtration Plant to SDWD's water
system also increased reliability and redundancy of the District's supplies.
Three active water reservoirs utilized for storage of water supplies are located within the District,
two of which the District has fiill ownership of (Balour Reservoir and the Encinitas Ranch
Reservoir). The District shares ownership of the Badger Clearwell and the Wanket Tank;however,
the Wankel Tank is currently out of service.
The City of Encinitas has also adopted the National Incident Management System(NIMS),which
establishes procedures and training programs for emergency response.
Emergency Response Plan
The District is currently updating its Emergency Response Plan pursuant to Section 2013(b)of the
American Water Infrastructure Act (AWIA) of 2018, which requires that community water
suppliers serving populations greater than 3,300 develop or update an Emergency Response Plan
that incorporates the findings of their risk and resilience assessments. The District's Emergency
Response Plan is expected to be completed by December 2021.
Draft Page 30-13
San Dieguito Water District
Water Shortage Contingency Plan
Emergency Storage Proiect and Suooly Reliability
In order to provide sufficient emergency water storage to supply to its member agencies during an
extended period, the SDCWA implemented the Emergency Storage Project (ESP) in 2014. The
ESP is a system of reservoirs, pipelines, pump stations, and other conveyance facilities intended
to improve San Diego's regional water storage capacity and allow stored emergency water to be
delivered to SDCWA's member agencies within San Diego County during a prolonged regional
interruption. The pipelines that carry imported water from MWD to San Diego cross several major
fault lines on their way to San Diego County. Consequently, an earthquake, drought, or other
disaster could interrupt San Diego County's imported water supply for up to six months. The ESP
facilities can be used to help deliver emergency water supplies to member agencies during two-
and six-month emergency events in which the region is either completely unable or only partially
able to receive imported water deliveries due to a disaster that renders their transmission system
inoperable. By providing interconnections within regional facilities, the ESP is designed to make
water available to the San Diego region even during catastrophic conditions when there is an
interruption in imported water deliveries.
The regional emergency water supply reservoirs(with their ESP capacity)are Olivenhain(18,000
AF),Lake Hodges(20,000 AF),and San Vicente(52,100 AF). The actual amount of ESP water to
be delivered to a particular member agency during an emergency event will depend on many
factors such as member agency demands, local supplies, infrastructure, availability of MWD
supplies, and duration of emergency. The ESP was designed to provide a total of 90,100 AF of
stored water to meet the region's emergency needs through at least 2030 and recent trends in
regional water demand indicate this volume of emergency storage will serve the region beyond
2045. SDCWA's Board of Directors may also authorize that supplies from the ESP be used in a
prolonged drought or other water shortage situations where imported and local supplies do not
meet 75%of the SDCWA's member agencies urban demands.
As discussed in the District's 2020 UWMP(Chapter 6—Water Supply Reliability Assessment),
the SDCWA anticipates that it will have more than enough available supply to meet its own
demands and the demands of its member agencies under a five-year multi-year drought scenario.
Therefore, if the District anticipates that its available local surface water supply (Lake Hodges)
will be less than projected, the District can augment supply and offset the anticipated deficit by
purchasing more water from the SDCWA.
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 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 muldhazard 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.
Draft Page 30-14
San Dieguito Water District
Water Shortage Contingency Plan
CWC 10632.5 requires an urban water supplier to include within its UWMP 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. Pursuant to CWC 10632.5(c), an urban water
supplier may comply with this requirement by submitting a copy of the most recently adopted
multi-hazard mitigation plan under the federal Disaster Mitigation Act of 2000 (Public Law 106-
390) if the multi-hazard mitigation plan addresses seismic risk.
Attachment A includes a copy of Section 4.3.4 of the Multi-Hazard Mitigation Plan for San Diego
County(MHM Plan),which addresses seismic risk,as well as Section 5.8 of the MHM Plan which
summarizes the potential hazards for the City of Encinitas and related goals, objectives, and
actions. The MHM Plan was prepared with input from the Water Authority and under the federal
Disaster Mitigation Act of 2000.
30.5 Communication Protocols
CWC IW32(a)(5)
Communication protocols and procedures to inform customers, the public interested parties,and local,
regional, and state governments,regarding, at a minimum,all of the following:
(A) Any current or predicted shortages as determined by the annual water supply and demand
assessment described pursuant to Section 10632.1.
(B)Any shortage response actions triggered or anticipated to be triggered by the annual water supply
and demand assessment described pursuant to Section 10632.1.
(C)Any other relevant communications.
Upon a water shortage declaration action by the General Manager (Level 1), the District will
increase its public education and outreach efforts to emphasize increased public awareness of the
need to implement the voluntary water conservation practices. Upon a water shortage declaration
action by the Board of Directors (Levels 2-6), the District will expand its public information
campaign to notify the public of the mandatory water conservation measures. The District would
need to provide notice of the water shortage rules and regulations to all residents and businesses
within its service area in the City of Encinitas, in addition to its customers of record, through a
variety of media and communications methods, such as print or internet.
Upon declaration of a Level I shortage, the General Manager may publish a notice of the
determination in one or more newspapers, including a newspaper of general circulation within the
District.Upon declaration of Level 2-6 shortage or Water Shortage Emergency,the District shall
coordinate with the City Manager of the City of Encinitas and shall publish a copy or summary of
the resolution in a newspaper used for publication of official notices at least one time within five
(5) days of the declaration. If the District establishes a water allocation under Water Shortage
Response Levels 4-6,the District shall provide notice of the allocation by including it in the regular
billing statement for water service fees or charges or by any other mailing to the address to which
the SDWD customarily mails the billing statement for fees or charges for ongoing water service.
Upon declaration of any water shortage condition level, the District may also post notice on its
website.
If possible, the District should activate its public information campaign prior to a formal water
shortage declaration to provide customers with advanced notice of impending water use
restrictions. The District could continually update its webpage to notify residents of current and
Draft Page 30-15
San Dieguito Water District
Water Shortage Contingency Plan
planned shortage levels and modify and expand the webpage, as necessary. During the recent
drought, the District utilized bill inserts to inform its customers of water shortage levels and the
associated mandatory demand reduction actions. Other actions that suppliers may take to increase
public outreach are contacting large water users and businesses that are most likely to be seriously
affected directly in writing and/or providing public notifications for non-English speakers.
Because the District aligns its water shortage response levels with the SDCWA, public outreach
and messaging campaigns conducted by SDCWA will also benefit the District as it triggers
different levels.
30.6 Compliance and Enforcement
CWC 10832(a)(6)
For an urban water supplier customer compliance, enforcement, appeab and exemption procedures
for tr/gpred shortage response actions as determined pursuant to Section 10632.2.
Any person who uses, causes, or permits the use of water in violation of the District's WSCP is
guilty of an offense punishable as established by the provisions of Article 30. Each day that a
violation of this ordinance occurs is counted as a separate offense. Violation of Article 30 may
result in issuance of a warning notice,fines,restriction of service,and/or discontinuance of service.
Administrative fines may be levied for each violation of a provision of this ordinance as shown in
Table 30-4.
Violation of a provision of Article 30 is also subject to enforcement through installation of a flow-
restricting device on the meter. Each willful violation of this ordinance may be prosecuted as a
misdemeanor punishable by imprisonment in the county jail for not more than 30 days and/or a
fine not exceeding S1,000, as authorized in CWC section 377. A willful and excessive violation
of the mandatory conservation measures and water use restrictions as set forth in Section 30.3 may
result in a discontinuance of service.

30.7 Consumption Reduction Methods
In addition to water use restrictions and prohibitions, the District implements consumption
reduction methods to reduce water demands within its service area. When a Level 1 condition is
declared, the District will expand its public education and outreach efforts to increase public
awareness of the need to implement water conservation practices. The District will continue to
increase public outreach and engagement efforts as needed upon triggering progressive water
shortage levels.
The District, in conjunction with local agencies and MWD, offers several ongoing rebate and
incentive programs to help its customers reduce water use,which in turn help the District reach its
targeted water use reductions. Actions taken by the District to reduce demands during each
shortage stage are presented in Table 30-5. The District's consumption reduction methods,
including rebate and incentive programs, are discussed in more detail in the District's UWMP.

30.8 Legal Authorities
CWC 10632(a)(7)
((A)A description of the legal authorities that empower the urban water supplier to implement and
enforce its shortage response actions specified in paragraph (4)that may include, but are not limited
to,statutory authorities, ordinances,resolutions, and contract provisions.
((B)A statement that an urban water supplier shall declare a water shortage emergency in accordance
with Chapter 3(commencing with Section 350)of Division 1. (see below)
((C)A statement that an urban water supplier shall coordinate with any city or county within which it
provides watersupplyservices for the possible proclamation of local emergency,as defined in Section
8558 of the Government Code.
Water Code Division 1,Section 350
Declaration of a water shortage emergency condition. The governing body of distributor of a public
watersupply, whether publicly or privatelyowned and including a mutual water company,shall declare
a water shortage emergency condition to prevail within the area served by such distributor whenever it
fords and determines that the ordinary demands and requirements of water consumers cannot be
satisfied without depleting the water supply of the distributor to the extent that there would be
insufiictent water for human consumption,sanitation, and fire protection.
The District has the legal authority to implement and enforce its water shortage contingency plan.
California Constitution article X, section 2 and CWC section 100 provide that water must be put
to beneficial use, the waste or unreasonable use or unreasonable method of use of water shall be
prevented, and the conservation of water is to be exercised with a view to the reasonable and
beneficial use thereof in the interest of the people and the public welfare.In addition,CWC section
375 provides the District with the statutory authority to adopt and enforce water conservation
restrictions, and CWC sections 350 et seq. authorize the District to declare a water shortage
emergency and impose water conservation measures when it determines that the District may not
be able to satisfy ordinary demands without depleting supplies to an insufficient level.
If necessary,the District shall declare a water shortage emergency in according with CWC Chapter
3 (commencing with section 350)of Division 1. Once having declared a water shortage, the Dis
is provided with broad powers to implement and enforce regulations and restrictions for managing
a water shortage. For example: CWC section 375(a)provides:
Notwithstanding any other provision of the law, any public entity which supplies
water at retail or wholesale for the benefit of persons within the service area or area
of jurisdiction of the public entity may, by ordinance or resolution adopted by a
majority of the members of the governing body after holding a public hearing upon
notice and making appropriate findings of necessity for the adoption of a water
conservation program, adopt and enforce a water conservation program to reduce
the quantity of water used by those persons for the purpose of conserving the water
supplies of the public entity.
(CWC section 375(a).) CWC section 375(b) grants the District with the authority to set prices to
encourage water conservation.
Under California law, including CWC Chapters 3.3 and 3.5 of Division 1, Parts 2.55 and 2.6 of
Division 6, Division 13, and article X, section 2 of the California Constitution, the District is
authorized to implement the water shortage actions outlined in this WSCP. In water shortage
Draft Page 30-18
San Dieguito Water District
Water Shortage Contingency Plan
cases, shortage response actions to be implemented will be at the discretion of the District and will
be based on an assessment of the supply shortage, customer response, and need for demand
reductions as outlined in this WSCP.
It is noted that upon proclamation by the Governor of a state of emergency under the California
Emergency Services Act(Chapter 7 (commencing with section 8550) of Division I of Title 2 of
the Government Code) based on drought conditions, the state will defer to implementation of
locally adopted water shortage contingency plans to the extent practicable.
30.9 Monitoring and Reporting
CWC 10632(a)(9)
For an urban retail water supplier, monitoring and reporting requirements and procedures that ensure
appropriate data is collected, tacked, and analyzed for the purposes of monitoring customer compliance
to meet state reporting requirements.
The methods for determining actual water use reductions are implemented on an ongoing basis.
All water received from the SDCWA is metered and monitored. Additionally,the District is fully
metered.The meters measure and record the water used by each connection within its service area
and keeps good records of the water meter readings. Water use from all customers can be retrieved
from these historical water meter records. The District also regularly performs meter accuracy
testing and meter replacement to ensure the accuracy of meter readings. When water use
restrictions are in place, and specifically when water allocations have been implemented, the
District closely monitors water use to ensure compliance with restrictions and to verify that
customers are not exceeding their set allocations. Because the District collects water use data on a
regularly scheduled basis as part of its customer billing process, it can calculate a baseline to
compare to current water use during times of drought, which can then be used to estimate actual
reductions in water use. If the trend in consumption is such that demand is greater than anticipated
supply,the Board of Directors will be notified so that corrective action(such as increased publicity
and enforcement or consideration of declaring the next higher stage)can be taken.
30.10Refinement Procedures
CWC 10632(a)(10)
Reevaluation and improvement procedures for systematically monitoring and evaluating the
functionality of the water shortage contingency plan in order to ensure shortage risk tolerance is
adequate and appropriate water shortage mitigation strategies are implemented as needed.
The District's WSCP is a living document and will need to be responsive to the effectiveness of
conservation measures in the midst of a water shortage. The District will analyze monthly
monitoring data and convene the Board of Directors to determine if adaptive measures need to be
taken to achieve the necessary shortage reduction levels. In the case that the water shortage
response measures are not working as planned, the District will add new actions or refine current
actions to achieve greater savings. Measures from a higher stage could be adopted into the current
stage, such as requiring leak repairs within 24 hours for Stages 3 and 4 rather than 48 hours. When
updates are needed,the District will coordinate with all appropriate City of Encinitas Departments
to refine the plan and provide updated information and measures to the Board of Directors for
approval.

(A) A description of potential revenue reductions and expense increases associated with activated
shortage response actions described in paragraph(4).
0 A description of mitigation actions needed to address revenue reductions and expense increases
associated with activated shortage response actions described in paragraph(4).
(C)A description of the cast of compliance with Chapter 33(commencing with Section 365)ofDivision
1.
In the event of a water shortage emergency,the District's WSCP would be activated to respond to
the applicable level of the shortage. With the activation of the District's drought policies, the
drought response stage water conservation measures would go into effect and the District would
be operating with reduced water sales. The amount of decreased water sales would depend on the
drought response stage under which the District would be operating.
With the implementation of the water conservation measures associated with the drought response
levels, the District may incur additional expenses. Some of these additional expenditures may
come from increased staffing, increased staff time needed to implement measures, or increased
costs of new supplies, transfers, or exchanges (by either the District or the SDCWA). Increased
expenses may be recovered b implementing demand reduction rates (drought rates volumetric

penalties, and civil penalties. When allocations are implemented, any person that uses water in
excess of the allocation shall be subject to a penalty in the amount of twice the District's existing
customers class commodity rate if under 115% of the allocation and four times the District's
existing customers class commodity rate if over 115%in excess of the allocation. The penalty for
excess water usage shall be cumulative to any other remedy or penalty that may be imposed for
violation of Article 30, as discussed in Section 30.6. Additionally, the District may use reserve
funds or defer non-critical maintenance or projects to help reduce expenses in the face of reduced
water sales during a water shortage emergency or to reallocate staff efforts to support drought
response actions.
The price of water is increasing, both as a commodity and with an overall decrease in available
supplies. If necessary, the District's water rates would be adjusted in response to the increasing
cost of water. Adjustments to the District's rate structure may offset potential losses in revenue
due to reduced sales. The District is currently in the process of conducting a rate study in
accordance with Proposition 218 and plans to coordinate this rate study with any rate adjustments
associated with this ordinance.
30.12 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 artificlallysupplied 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.
Draft Page 30-20
San Dieguito Water District
Water Shortage Contingency Plan
The District uses the term "ornamental" when referring to water features that are artificially
supplied with water and are not swimming pools or spas (e.g., ornamental fountains, ornamental
pond, ornamental like), as well as the term "decorative water feature". Table 30-3 specifies
shortage response actions that are applicable to these ornamental water features, distinct from
pools or spas. Water shortage response actions also distinguish between ornamental water features
and artificial water features that support aquatic life or livestock in the action itself.

4.3.4 Earthquake
4.3.4.1 Nature of Hazard
An earthquake is a sudden motion or trembling that is caused by a release of strain accumulated within or
along the edge of the Earth's tectonic plates. The effects of an earthquake can be felt far beyond the site of
its occurrence.They usually occur without warning and,after just a few seconds,can cause massive damage
and extensive casualties. Common effects of earthquakes are ground motion and shaking, surface fault
ruptures,and ground failure.Ground motion is the vibration or shaking of the ground during an earthquake.
When a fault ruptures, seismic waves radiate, causing the ground to vibrate. The severity of the vibration
increases with the amount of energy released and decreases with distance from the causative fault or
epicenter. Soft soils can further amplify ground motions. The severity of these effects is dependent on the
amount of energy released from the fault or epicenter. One way to express an earthquake's severity is to
compare its acceleration to the normal acceleration due to gravity.The acceleration due to gravity is often
called"g".A 100%g earthquake is very severe.More damage tends to occur from earthquakes when ground
acceleration is rapid. Peak ground acceleration(PGA) is a measure of the strength of ground movement.
PGA measures the rate in change of motion relative to the established rate of acceleration due to gravity
(980 cm/sec/sec).PGA is used to project the risk of damage from future earthquakes by showing earthquake
ground motions that have a specified probability(101/o, 5%, or 2%)of being exceeded in 50 years. These
ground motion values are used for reference in construction design for earthquake resistance. The ground
motion values can also be used to assess relative hazard between sites,when making economic and safety
decisions.
Another tool used to describe earthquake intensity is the Richter scale. The Richter scale was devised as a
means of rating earthquake strength and is an indirect measure of seismic energy released. The scale is
logarithmic with each one-point increase corresponding to a 10-fold increase in the amplitude of the seismic
shock waves generated by the earthquake. In terns of actual energy released, however, each one-point
increase on the Richter scale corresponds to about a 32-fold increase in energy released. Therefore, a
magnitude(M)7 earthquake is 100 times(10 X 10)more powerful than a M5 earthquake and releases 1,024
times (32 X 32) the energy. An earthquake generates different types of seismic shock waves that travel
outward from the focus or point of rupture on a fault.Seismic waves that travel through the earth's crust are
called body waves and are divided into primary(P)and secondary(S)waves.Because P waves move faster
(1.7 times)than S waves they arrive at the seismograph first.By measuring the time delay between arrival
of the P and S waves and knowing the distance to the epicenter, seismologists can compute the Richter
scale magnitude for the earthquake.
The Modified Mercalli Scale (MMI) is another means for rating earthquakes, but one that attempts to
quantify intensity of ground shaking. Intensity under this scale is a function of distance from the epicenter
(the closer to the epicenter the greater the intensity),ground acceleration, duration of ground shaking, and
degree of structural damage. This rates the level of severity of an earthquake by the amount of damage and
perceived shaking(Table 4.3-1).

Appendix A - Excerpts from San Diego County Multi-Hazard Mitigation Plan
Several major active faults exist in San Diego County, including the Rose Canyon, La Nacion, Elsinore,
San Jacinto, Coronado Bank and San Clemente Fault Zones. The Rose Canyon Fault Zone is part of the
Newport-Inglewood fault zone, which originates to the north in Los Angeles, and the Vallecitos and San
Miguel Fault Systems to the south in Baja California(see Figure 4.3.3). The Rose Canyon Fault extends
inland from La Jolla Cove, south through Rose Canyon, along the east side of Mission Bay, and out into
San Diego Bay. The Rose Canyon Fault is considered to be the greatest potential threat to San Diego as a
region,due to its proximity to areas of high population.The La Nacion Fault Zone is located near National
City and Chula Vista. The Elsinore Fault Zone is a branch of the San Andreas Fault System. It originates
near downtown Los Angeles,and enters San Diego County through the communities of Rainbow and Pala;
it then travels in a southeasterly direction through Lake Henshaw, Santa Ysabel, Julian; then down into
Anza-Borrego Desert State Park at Agua Caliente Springs,ending at Ocotillo,approximately 40 miles east
of downtown. The San Jacinto Fault is also a branch of the San Andreas Fault System. This fault branches
off from the major fault as it passes through the San Bernardino Mountains. Traveling southeasterly, the
fault passes through Clark Valley, Borrego Springs, Ocotillo Wells, and then east toward El Centro in
Imperial County.This fault is the most active large fault within County of San Diego.The Coronado Bank
fault is located about 10 miles offshore. The San Clemente Fault lies about 40 miles off La Jolla and is the
largest offshore fault at 110 miles or more in length (Unified San Diego County Emergency Services
Organization Operational Area Emergency Plan,2014).
4.3.4.2 Disaster History
Historic documents record that a very strong earthquake struck San Diego on May 27, 1862, damaging
buildings in Old Town and opening up cracks in the earth near the San Diego River mouth.This destructive
earthquake was centered on either the Rose Canyon or Coronado Bank faults and descriptions of damage
suggest that it had a magnitude of about 6.0(M6).The strongest recently recorded earthquake in San Diego
County was a M5.3 earthquake that occurred on July 13, 1986 on the Coronado Bank Fault,25 miles west
of Solana Beach. In recent years there have been several moderate earthquakes recorded within the Rose
Canyon Fault Zone as it passes beneath the City of San Diego. Three temblors shook the city on 17 June
1985(M3.9,4.0,3.9)and a stronger quake occurred on 28 October 1986(M4.7)(Demere,SDNHM website
2003). The most recent significant earthquake activity occurred on June 15, 2004 with a M5.3 on the San
Diego Trough Fault Zone approximately 50 miles SW of San Diego. It was reported as an IV on the MMI
(Southern California Seismic Network).
4.3.4.3 Location and Extent/Probability of Occurrence and Magnitude
Figure 4.3.3 displays the location and extent of the profiled earthquake hazard areas for San Diego County.
This is based on a USGS earthquake model that shows probabilistic peak ground acceleration for every
location in San Diego County.Since 1984,earthquake activity in San Diego County has increased twofold
over the preceding 50 years(Demere, SDNHM website 2003). All buildings that have been built in recent
decades must adhere to building codes that require them to be able to withstand earthquake magnitudes that
create a PGA of 0.4 or greater.Ongoing field and laboratory studies suggest the following maximum likely
magnitudes for local faults: San Jacinto(M6.4 to 7.3),Elsinore(M6.5 to 7.3), Rose Canyon(M6.2 to 7.0),
La Nacion(M6.2 to 6.6),Coronado Bank(M6.0 to 7.7),and San Clemente(M6.6 to 7.7)(Demere,SDNHM
website 2003).
Appendix A - Excerpts from San Diego County Multi-Hazard Mitigation Plan
Data used to profile earthquake hazard included probabilistic PGA data from the United States Geological
Survey (USGS) and a Scenario Earthquake Shake map for Rose Canyon from the California Integrated
Seismic Network(CISN)(refer to Attachment A for complete data matrix). From these data,the HMWG
determined that risk level for earthquake is determined to be high if an area lies within a 0.3 or greater PGA
designation. Earthquakes were modeled using HAZUS-MH, which uses base information to derive
probabilistic peak ground accelerations much like the PGA map from USGS that was used for the profiling j
process.
The potential for an earthquake in the San Diego region is considered somewhat likely.

4.4.2.4 Earthquake, Liquefaction and Earthquake-Induced Landslides
The data used in the earthquake hazard assessment were: 100-, 250-, 500-, 750-, 1000-, 1500-, 2000-,and
2500-year return period USGS probabilistic hazards. Soil conditions for San Diego County as developed
by USGS were also used,which allowed for a better reflection of amplification of ground shaking that may
occur.The HAWS software model,which was developed for FEMA by the National Institute of Building
Services as a tool to determine earthquake loss estimates,was used to model earthquake and flood for this
assessment. This software program integrates with a GIS to facilitate the manipulation of data on building
stock, population, and the regional economy with hazard models. PBS&J updated this model in 2003 to
HAZUS-MH (Multiple Hazard), which can model earthquake and flood, along with collateral issues
associated with each model, such as liquefaction and landslide with earthquakes. This software was not
released prior to the beginning of the planning process;however,PBS&J performed vulnerability and loss
estimation models for earthquakes and flood for this project using the newer model.
Additionally, the earthquake risk assessment explored the potential for collateral hazards such as
liquefaction and earthquake-induced landslides.Three cases were examined,one case with shaking only,a
second case with liquefaction potential, and a third with earthquake-induced landslides. Once the model
was complete, the identified vulnerable assets were superimposed on top of this information, resulting in
three risklloss estimates: 1) the aggregated exposure and building count (both dollar exposure and
population) at the census block level for residential and commercial occupancies, 2) the aggregated
population at risk at the census block level, and 3) the critical infrastructure at risk (schools, hospitals,
airports, bridges, and other facilities of critical nature). These results were then aggregated and presented
by hazard risk level per jurisdiction. Results for residential and commercial properties were generated as
annualized losses, which average all eight of the modeled return periods (100-year through 2500-year
events). For critical facility losses it was helpful to look at 100-and 500-year return periods to plan for an
event that is more likely to occur in the near-term. In the near term, a 500-year earthquake would cause
increased shaking,liquefaction and landslide,which would be expected to increase loss numbers.Exposure
for annualized earthquake included buildings and population in the entire county because a severe or worst
case scenario earthquake could affect any structure in the County. Furthermore,the annualized earthquake
loss table also shows potential collateral exposure and losses from liquefaction and landslide separately;
this is the additional loss from earthquake due to liquefaction or landslide caused by earthquakes and should
be added to the shaking-only loss values to get the correct value.(The collateral liquefaction and landslide
loss results for critical facilities were included with earthquake in Tables 4.4-11 and 4.4-12,to plan for an
event that is more likely to occur in the near-term as discussed above).
Table 4.4-10 provides a breakdown of potential exposure and losses due to annualized earthquake events
by jurisdiction. Tables 4.4-11 and 4.4-12 provide a breakdown of infrastructure and critical facility losses
from 100-year and 500-year earthquakes, respectively. Approximately 2,800,000 people may be at risk
from the annualized earthquake and earthquake-induced liquefaction hazards. In addition, special
populations at risk that may be impacted by the earthquake hazard in San Diego County include 13,689
low-income households and 24,316 elderly persons.

The City of Encinitas (Encinitas) reviewed a set of jurisdictional-level hazard maps including detailed
critical facility information and localized potential hazard exposure/loss estimates to help identify the top
hazards threatening their jurisdiction. In addition, LPGs were supplied with exposure/loss estimates for
Encinitas summarized in Table 5.8-1. See Section 4.0 for additional details.

Data consistent with the Encinitas-Solana Beach Coastal Storm Damage Reduction Project
" Represents best available data at this time.
After reviewing the localized hazard maps and exposure/loss table above, the following hazards were
identified by the Encinitas LPG as their top six, based on their probability and potential impact. A brief
rationale for including each of these is included.
• Earthquake: On November 22, 1800, a 6.5 magnitude occurred on the Rose Canyon fault
offshore from Oceanside. It cracked adobe walls at the missions of San Diego de Alcala and
San Juan Capistrano. Other notable local earthquakes include a magnitude 6.0 earthquake
centered on the Rose Canyon or Coronado Band faults on May 27, 1862, and a magnitude 5.4
earthquake centered off the coast of Oceanside on the Coronado Bank Fault on July 13, 1986.
The geographic extent of this hazard is citywide. A greater percentage of the city's population
is potentially exposed to this hazard relative to other hazards, and potential losses from an
earthquake would be comparatively larger in most cases.
City of Encinitas I
Appendix A - Excerpts from San Diego County Multi-Hazard Mitigation Plan
SECTIONFIVE Goals,objectives and Actions
The Rose Canyon Fault lies offshore (2.5 miles west of the city at its closest point) and is
capable of generating a magnitude 6.2 to 7.2 earthquake that could potentially damage
dwellings and infrastructure throughout the city. A magnitude 6.9 earthquake on the Rose
Canyon Fault could potentially result in a peak ground acceleration of .40 within downtown
Encinitas and the Coast Highway 101 corridor. These areas of the city are more likely to suffer
heavier damage and greater human losses than other parts of the city because of the presence of
older buildings (including 19 unreinforced masonry buildings and 27 two-story, multi-unit
buildings constructed prior to 1976), a relatively higher population density and softer soils
susceptible to liquefaction,lurch cracking,lateral spreading and local subsidence.
• Wildfire: A significant number of Encinitas residents live within the wildland-urban interface.
The geographic extent of this hazard includes the following areas of the city, for the most part:
1) Saxony Canyon; 2) South El Camino ReaUCrest Drive; and 3) Olivenhain. Properties in
these and other smaller areas are susceptible to wildfire because they are situated near open
space and canyons containing heavy fuel loads. Reoccurring periods of low precipitation have
increased the risk of wildfires in the region. A greater percentage of the population is
potential) exposed to wildfires and potential losses from this hazard are comparatively larger
Y P P P Y
than those associated with a dam failure, flooding, coastal bluff failures or hazardous materials
incidents. Recent wildfire events in Encinitas include the Harmony Grove Fire in 1996, which
resulted in the loss of three homes and evacuation and sheltering of hundreds of residents.
• Dam Failure: Geologists estimate that a magnitude 7.5 earthquake from the Elsinore Fault 11
miles east of Lake Wohlford could result in a failure of its hydraulic fill dam. The geographic
extent of this hazard is limited to the persons and properties within the inundation path
surrounding Escondido Creek and San Elijo Lagoon. The dam inundation path is larger than the
Escondido Creek 100-year floodway and a greater number of persons and properties are
exposed to this hazard compared to coastal bluff failures and flooding. Major arterials within
the inundation path include El Camino Del Norte, Rancho Santa Fe Road, Manchester Avenue
and Coast Highway 101. The failure of Wohlford Dam (1895) and Dixon Reservoir Dam
(1970) could possibly threaten city facilities and infrastructure (including the San Elijo Water
Reclamation Facility, Cardiff and Olivenhain sewer pump stations and the San Dieguito Water
District 36 high pressure supply line) and educational facilities (Mira Costa College) located
in and adjacent to the inundation pith. Although exposure to loss of property is significant,the
potential for loss of life is limited because of the length of time before flood wave arrival
(approximately 1 % hours) allowing for aggressive warning and evacuation measures to be
initiated by the city.
The Olivenhain Dam (2003) is a concrete gravity dam located on a tributary of Escondido
Creek,just west of Lake Hodges, holding 24,000 acre feet. Stanley Mahr Reservoir(1981) is a
small, earth filled embankment dam located on a tributary of Encinitas Creek in San Marcos
with a capacity of approximately 200 acre feet. A failure of Mahr Reservoir in Carlsbad would
produce flooding along Encinitas Creek (which flows into Batiquitos Lagoon) in the northern
portion of the city. Emergency Action Plans have been developed for these dams. The risk of
failure of both dams in relatively low due to their age and construction and existing surveillance
and inspection measures.
• Coastal Bluff Failures: Geographic extent of the hazard is limited primarily to the Encinitas
coastal sandstone bluffs. After the El Nino storms of 1982-1983, Encinitas beaches were
stripped of vertical sand up to 20 feet deep putting the coastal bluffs and homes in jeopardy of
City of Encinitas 2
Appendix A - Excerpts from San Diego County Multi-Hazard Mitigation Plan
SECTIONFIVE Goals,Objectives and Actions
collapsing into the sea. Furthermore, the shoreline segments at Moonlight Beach and Cardiff-
by-the-Sea are extremely vulnerable to coastal inundation from potential future sea level rise.
In 2000, unstable cliffs at Beacon's Beach in Encinitas caused a landslide that killed a woman
sitting on the beach. The recreational bicycle path along the seaside of Highway 101 was
undermined in 2010.
Erosion studies have been conducted for Encinitas, Solana Beach and Del Mar.Various degrees
of coastal bluff erosion occur annually and coastal bluff failures have resulted in limited loss of
life. As a result, negotiations with the California Coastal Commission are underway to develop
a comprehensive coastal bluff policy towards coastal bluff top development. A smaller
percentage of the population is exposed to this hazard relative to earthquakes, wildfires and
dam failures and the potential for losses is comparatively less.
• Flooding: The geographic extent of this hazard is limited to 1)Encinitas coastline, particularly
"Restaurant Row" in Cardiff(south of San Elijo State Beach Campgrounds); 2) Escondido,
Encinitas and Cottonwood Creeks; and 3) low-lying areas of Leucadia and Old Encinitas. The
city has experienced some property-related losses resulting from localized flooding in Leucadia
and coastal flooding in Cardiff, but not loss of life. Winter storms in 1997, 2005-2006 and
2010-2011 resulted in significant damage and required emergency protective measures, debris
removal and reconstruction of infrastructure. The associated recovery costs (FEMA public
assistance)for the 2005-06 event was over$500,000.
• Hazardous Materials: One major freeway (Interstate 5), one railway and a major liquefied
petroleum transmission pipeline pass through the community. This hazard is addressed in
Attachment A.

5.8.4 Goals, Objectives and Actions
Listed below are Encinitas' specific hazard mitigation goals, objectives and related potential actions. For
each goal, one or more objectives have been identified that provide strategies to attain the goal. Where
appropriate,the City has identified a range of specific actions to achieve the objective and goal.
The goals and objectives were developed by considering the risk assessment findings, localized hazard
identification and loss/exposure estimates, and an analysis of the jurisdiction's current capabilities
assessment. These preliminary goals, objectives and actions were developed to represent a vision of long-
term hazard reduction or enhancement of capabilities. To help in further development of these goals and
objectives, the LPG compiled and reviewed current jurisdictional sources including the City's planning
documents, codes, and ordinances. In addition,City representatives met with consultant staff'and/or OES
to specifically discuss these hazard-related goals, objectives and actions as they related to the overall
Plan. Representatives of numerous City departments involved in hazard mitigation planning provided
input to the Encinitas LPG. The San Dieguito Water District is a subsidiary district to the City of
Encinitas and its goals,objectives and actions are included in this document.The Encinitas LPG members

5.8.5 Prioritization and Implementation of Action Items
Once the comprehensive list of jurisdictional goals, objectives, and action items listed above was
developed, the proposed mitigation actions were prioritized. This step resulted in a list of acceptable and
realistic actions that address the hazards identified in each jurisdiction. This prioritized list of action items
was formed by the LPG weighing STAPLEE criteria.
The Disaster Mitigation Action of 2000 (at 44 CFR Parts 201 and 206) requires the development of an
action plan that not only includes prioritized actions but one that includes information on how the
prioritized actions will be implemented. Implementation consists of identifying who is responsible for
which action, what kind of funding mechanisms and other resources are available or will be pursued, and
when the action will be completed.
The prioritized actions below reflect progress in local mitigation efforts as well as changes in
development.

Coordinating Individual/Organization: Public Works Department
Potential Funding Source: Grant Funding
Implementation Timeline: January 2015—2020
Description: The coastal community of Leucadia has a chronic history of rainwater
flooding. This occurs primarily in the vicinity of its main north-south
routes, N. Coast Highway 101 and N. Vulcan Avenue. This long-term
project is contingent on significant grant funding(due to its overall cost)
and seeks to construct an underground storm drain system(using 3 phase
conventional methods) along Highway 101 with the capacity to convey
the peak flow rate from the 100 year frequency storm event.
