AGENDA ITEM
DATE: June 19, 2024
TO: Mayor and City Council
FROM: Ann Eifert, Director of Financial Services/City Treasurer
SUBJECT: APPROPRIATIONS LIMIT – FISCAL YEAR 2024-25
Recommended Action:
Adopt a Resolution setting the Proposition 4 (GANN) Appropriations limit for Fiscal Year (FY) 2024-25 at $58,378,143.
Fiscal Impact:
None.
Background:
Pursuant to Article XIIIB of the California Constitution, the City must compute an annual appropriations limit (known as the Gann Limit), which places a ceiling on the total amount of tax revenues the City can appropriate annually. The limit is adjusted each year using the following factors: 1) the percentage change in California Per Capita Income, or the change in the City’s Assessed Valuation due to new non-residential construction, whichever is greater; and 2) the percentage change in the Citywide, or Countywide population, whichever is greater. As required by Government Code Section 7910, the City Council is being asked to formally adopt by resolution the Appropriations Limit for FY 2024-25.
Discussion:
The California per capita personal income percentage change as provided by the Department of Finance is 3.62% for FY 2024-25. The percentage change in the local assessment roll from the preceding year for the City due to the addition of local non- residential new construction is 1.44%. Section 7901 of the Government Code allows entities to use either the population increase within the City or the increase within the County. This year the estimated population change for the City was negative 0.43% and the County was 0.31%.
26
It is recommended that the City Council adopt the percentage change in the County population and the percentage change in the California per capital personal income from the preceding year for use in the adjustment of the Appropriations Limit for Fiscal Year 2024-25. The appropriations limit for FY 2024-25 is $58,378,143 and the budget subject to the limit is $19,534,385; therefore, the City is in compliance with Government Code requirements. For FY 2024-25, the City will be utilizing 33.46% of its appropriations limit.

AGENDA ITEM
DATE: June 19, 2024
TO: Mayor and City Council
FROM: Ann Eifert, Director of Financial Services
SUBJECT: AGREEMENT WITH PROCURE AMERICA, INC. FOR COST
REDUCTION CONSULTING SERVICES
Recommended Actions:
1. Approve an agreement with Procure America, Inc. for cost reduction consulting services; and
2. Authorize the City Manager to execute a professional services agreement with Procure America, Inc. in the amount not-to-exceed $55,000 for five years.
Fiscal Impact:
Procure America proposes to review the City’s electric, gas, and water utility rates, and will receive 30% of the savings realized by the City for a period of five years. The City’s utility payments total approximately $0.7 million for the current year and Procure America has estimated that about 5% or $35,000 can be saved annually. If savings are achieved, Procure America will receive about $10,500 annually, or $55,000 over the next five years.
The review of the City’s utility payments is at no cost to the City if savings are not identified.
Background:
Procure America, Inc. provides government agencies with services designed to identify cost savings in utilities, telecommunications, print management, and other services.
Procure America achieves savings for agencies by having subject matter experts review and analyze invoices and billing rates and working with the utility companies to set forth changes to the City’s current rate structures.
Discussion:
The City’s Purchasing Policy allows competitive bidding requirements to be waived if there is an advantage to utilizing an existing competitively bid agreement issued by another agency. In 2019, the County of Orange established a Regional Cooperative 38
Agreement with Procure America for cost reduction consulting services. The City’s proposed agreement utilizes the terms and conditions negotiated by the County. Procure America has also provided similar services to the City of Yorba Linda, City of Irvine, City of San Clemente, and the County of San Diego.
In an effort to reduce costs within the City, Staff is recommending that an agreement be approved to review the City’s electric, gas, and water utility payments. Procure America will waive any fees associated with the review if no savings are realized.

AGENDA ITEM
DATE: June 19, 2024
TO: Mayor and City Council
FROM: Captain Alan Villanueva, Chief of Police Services Sarah Limones, Sr. Emergency Management Program Coordinator SUBJECT: LOCAL HAZARD MITIGATION PLAN ADOPTION
Recommended Action:
Adopt the 2024 City of Aliso Viejo Local Hazard Mitigation Plan (LHMP).
Summary:
The City initiated the preparation of its first Local Hazard Mitigation Plan (LHMP) to become eligible for FEMA hazard mitigation grants. The preparation of this plan included the creation of a Hazard Mitigation Planning Committee (HMPC) from across the various City departments, key stakeholders, and the public. To assist with the preparation, the City selected Atlas Planning Solutions through a competitive bid process. The consulting firm was tasked with managing the update process with assistance from the HMPC which provided current and outstanding data, input on goals and policies, reviewed working drafts once available, and ultimately assisted in authoring the LHMP. The plan was also required to be made available to the public during the planning process to allow for input, questions, review and comment.
Fiscal Impact:
The City received a FEMA Hazard Mitigation Planning Grant in the amount of $125,000 to cover the costs associated with plan preparation. As required by the grant, a local match of 25% of total funding was provided by the City, which was met through in-kind contributions, which included staff time. There is no additional financial impact to adopt the LHMP.
Background:
The City of Aliso Viejo prepared its first LHMP to ensure that the natural and human- caused hazards the City faces are adequately understood and analyzed. In 2023 the City initiated the preparation of the LHMP. The City felt that completing this plan would allow for a better understanding of the issues and concerns associated with hazards, allow for 60
development of goals and strategies to address these hazards, and create opportunities to better integrate the plan into other planning documents and City functions.
The LHMP is governed by the Federal Emergency Management Agency (FEMA), under the Stafford Act as amended by the Disaster Mitigation Act of 2000 (DMA 2000). The City’s Local Hazard Mitigation Plan is required to be updated to ensure that a community focuses on the reduction of loss of life and property, human suffering, and economic disruption, and provides disaster assistance for costs resulting from natural disasters.
This must be done in order to maintain eligibility for federal grant opportunities under the Hazard Mitigation Grant Program (HMGP), Flood Mitigation Assistance (FMA), and Building Resilient Infrastructure and Communities (BRIC) programs.
One of the many requirements to receive State and Federal approval includes incorporating community feedback, as well as developing a robust planning team of key community stakeholders with expertise on local hazards. Input was received from community members through on-line surveys and outreach events conducted within the City. The first planning meeting took place on April 12, 2023. The 2024 LHMP received approval (pending adoption) from the Federal Emergency Management Agency on May 23, 2024. Once adopted, the final resolution (attached) will be submitted to FEMA to meet the continual update requirements of the Disaster Mitigation Act of 2000 and maintain the City's eligibility for mitigation grant funding.

68 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
1 CHAPTER 1 – INTRODUCTION
PLAN PURPOSE AND AUTHORITY
Hazard events can lead to injuries or death, affect the overall health and safety of a community, damage or destroy public and private property, harm ecosystems, and disrupt key services.
Although the hazard event often gets the most attention, it is only part of a larger emergency management cycle.
Emergency planners and
responders can take steps during
the cycle's response, recovery,
mitigation, and preparedness
phases to minimize the harm
caused by a disaster. The City of
Aliso Viejo 2023 Local Hazard
Mitigation Plan (LHMP) focuses on
optimizing the mitigation phase of
the process . Mitigation involves
making a community more resilient so that when hazard events do ultimately occur, the community suffers minor damage and can recover more quickly and effectively. Mitigation differs from preparedness, which involves advanced planning for how best to respond when a disaster occurs or is imminent. For example, a policy to make homes structurally stronger so they suffer minor damage during an earthquake is a mitigation action, while fully equipping emergency shelters to accommodate people who lose their homes in an earthquake is a preparedness action. Some activities may qualify as both.
Like other communities, the City of Aliso Viejo (City) could potentially suffer severe harm from hazard events. Although large disasters may cause widespread devastation, minor disasters can have more substantial effects. The City cannot make itself completely immune to hazard events, but this LHMP can help make the community a safer place to live, work, and play. This LHMP provides a comprehensive assessment of the c ity’s threats from natural and human-caused hazard events and a coordinated strategy to reduce these threats. It identifies resources and information to help community members, City staff, and local officials understand local threats and make informed decisions. The LHMP can also support increased coordination and collaboration between the City, other public agencies, local employers, service providers, community members, and other key stakeholders.
FEDERAL AUTHORITY
The City is not required to prepare an LHMP, but state and federal regulations encourage it. The federal Robert T. Stafford Disaster Relief and Emergency Act, amended by the Disaster Management Act of 2000, creates a federal framework for local hazard mitigation planning. It states that jurisdictions that wish to be eligible for federal hazard mitigation grant funding must prepare a hazard mitigation plan that meets a particular set of guidelines and submit this plan to

2 the Federal Emergency Management Agency (FEMA) for review and approval. The following regulations and guidelines apply to this plan:
Federal Laws
• Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act), as amended.
Federal Regulations
• 44 CFR Part 201 Mitigation Planning.
• 44 CFR, Part 60, Subpart A, including § 60.3
Flood plain management criteria for flood-
prone areas.
• 44 CFR Part 77 Flood Mitigation Grants.
• 44 CFR Part 206 Subpart N. Hazard
Mitigation Grant Program.
Federal Guidance
• FEMA Local Mitigation Planning Policy
Guide (FP 206-21-0002), effective April 19,
2023
STATE AUTHORITY
California Government Code Sections 8685.9 and
65302.6
California Government Code Section 8685.9 (also
known as Assembly Bill 2140) limits the State of
California's share of disaster relief funds paid out to local governments to 75 percent of the funds not paid
for by federal disaster relief efforts unless the jurisdiction has adopted a valid hazard mitigation plan consistent
with the Disaster Management Act of 2000 and has
incorporated the hazard mitigation plan into the
jurisdiction's general plan. The State may cover over 75 percent of the remaining disaster relief costs in these cases.
All cities and counties in California must prepare a general plan, including a safety element that addresses various hazard conditions and other public safety issues. The safety element may be a stand-alone chapter or incorporated into another section, as the community wishes. California Government Code Section 65302.6 indicates that a community may adopt an LHMP into its safety element if the LHMP meets applicable state requirements. This allows communities to use the LHMP to satisfy state requirements for safety elements. As the General Plan is an overarching long-term plan for community growth and development, incorporating the LHMP into it creates a stronger mechanism for implementing the LHMP.
California Government Code Section 65302 (g)(4)
California Government Code Section 65302 (g)(4), also known as Senate Bill (SB) 379, requires that the safety element of a community's general plan address the hazards created or exacerbated by climate change. The safety element must identify how climate change is expected to affect hazard conditions in the community and include measures to adapt and be more resilient to these anticipated changes.
FEMA Local Mitigation Planning Policy
Guide provides the official policy and
interpretation of the applicable statutes
and mitigation planning regulations in 44
Code of Federal Regulations
70 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
3 Because the LHMP can be incorporated into the safety element, including these items in the LHMP can satisfy the state requirement. SB 379 requires that climate change be addressed in the safety element when the LHMP is updated after January 1, 2017, for communities that already have an LHMP or by January 1, 2022, for communities without an LHMP.
This LHMP is consistent with current standards and regulations, as outlined by the California Office of Emergency Services (Cal OES) and FEMA. It uses the best available science, and its mitigation actions/strategies reflect best practices and community values. It meets the requirements of current state and federal guidelines and makes the City eligible for all appropriate benefits under state and federal law and practices. Note that while FEMA is responsible for reviewing and certifying this LHMP, and Cal OES is responsible for conducting a preliminary review, it does not grant FEMA or Cal OES an increased role in the governance of the city or authorize either agency to take any specific action in the community.
PLAN ORGANIZATION AND USE
The Aliso Viejo LHMP is both a reference document and an action plan. It has information and resources to educate readers and decision-makers about hazard events and related issues and a comprehensive strategy that the City and community members can follow to improve resilience in the city. It is divided into the following chapters:
Chapter 1: Introduction. This chapter describes the Plan's background, its goals and objectives, and the process used in its development.
Chapter 2: Community Profile. This chapter discusses Aliso Viejo's history , physical setting, land use, demographics, and other important community characteristics.
Chapter 3: Hazard Assessment. This chapter identifies and describes the hazards that threaten Aliso Viejo and discusses past and future events and the effects of climate change.
Chapter 4: Vulnerability Assessment. This chapter describes each hazard's threat to Aliso Viejo’s key facilities and community members, including socially vulnerable individuals.
Chapter 5: Mitigation Strategy. This chapter lists the mitigation actions to reduce Aliso Viejo’s vulnerability to hazard events and provides an overview of the community's existing capabilities to improve hazard resilience.
Chapter 6: Plan Maintenance. This chapter summarizes implementing, monitoring, and updating the LHMP and opportunities for continued public involvement.
PREVIOUS ALISO VIEJO LHMP
This is the City of Aliso Viejo’s first LHMP, which will open the eligibility, once approved, and adopted by the City Council, to apply for FEMA grants for hazard mitigation projects and monetary relief during emergency situations.
PREVIOUS PLAN INTEGRATION
As this is Aliso Viejo’s first LHMP, the City will be looking to integrate this document into other planning documents and processes. To ensure this future integration occurs, Chapter 6 of this plan includes additional guidance on how to best integrate the LHMP into the General Plan Safety Element, Emergency Operations Plan, and other planning mechanisms used by the City. 71 City of Aliso Viejo 2024 Local Hazard Mitigation Plan

PLAN GOALS
This Plan was developed to increase resilience in Aliso Viejo broadly, relying on the following goals:
GOAL-1: Protect against threats from natural hazards to life, injury, and property damage for Aliso Viejo residents and visitors.
GOAL-2: Increase public awareness of potential hazard events.
GOAL-3: Preserve critical services and functions by protecting key facilities and infrastructure.
GOAL-4: Protect natural systems from current and future conditions.
GOAL-5: Coordinate mitigation activities among City departments, neighboring jurisdictions, and with federal agencies.
GOAL-6: Prepare for long-term changes in hazard conditions. 72 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
5 As the City’s first LHMP, these goals shall serve as the foundation for all subsequent versions of this plan as it is updated every five years to maintain FEMA grant eligibility and maintain alignment with the City and its communities’ focus. With these newly established goals, these new priorities are anticipated to help inform and ensure greater consistency with the City's General Plan Safety Element over the next five years.
PLANNING PROCESS
State and federal guidance for LHMPs does not require that jurisdictions follow a standardized planning process. FEMA encourages communities to create a planning process that reflects local values, goals, and characteristics. FEMA does suggest a general planning process that follows the steps identified below:
The planning process used to create this plan for the City of Aliso Viejo is described below.
HAZARD MITIGATION PLANNING COMMITTEE
The City established a Hazard Mitigation Planning Committee (hereafter referred to as the HMPC). The HMPC comprises representatives from key city departments and stakeholders from local and regional agencies and companies that are key to hazard mitigation activities. Table 1-2 identifies the members who were invited and/or attended HMPC meetings.

HMPC Meeting #1 (April 12, 2023): The HMPC members confirmed the project goals and responsibilities. They revised the community engagement and outreach strategy, confirmed, prioritized the hazards included in the Plan, and identified critical threat assessment facilities.
HMPC Meeting #2 (May 25, 2023): Members held a detailed discussion about the hazard prioritization, results of the hazards assessment and mapping, and the risk assessment that showed the areas, populations, and assets facing elevated risk and vulnerability.
HMPC Meeting #3 (June 19, 2023): The HMPC discussed and reviewed mitigation actions and strategies, made revisions, and assigned priorities.
Invitations and materials for meetings were provided via email. Appendix A contains copies of invitations, meeting agendas , sign-in sheets, and other relevant materials distributed for these meetings.
PUBLIC ENGAGEMENT
Under FEMA guidelines, local hazard mitigation planning processes should create opportunities for the public to be involved in plan development—at a minimum, during the initial drafting stage and plan approval. The HMPC chose to go beyond minimum standards and conduct more extensive community outreach to help ensure that the LHMP reflects community values, concerns, and priorities. The HMPC developed a community engagement and outreach strategy to guide all public engagement activities. To ensure all residents were aware of the project, Aliso Viejo staff conducted the following activities:

• LHMP city webpage (see below)
• eNews newsletters
• English and Spanish flyers at city facilities
• Promotion at City Meetings/ Events (see below)
• Promotion at City Facilities (City Hall, etc…) with signage on plan review content and QR codes for the Hazard Mitigation Survey were posted at the front desk. • Information included in community brochure mailed to every residence in the city • Information shared with Schools; and
• Information shared with businesses via the Chamber of Commerce
STAKEHOLDER ENGAGEMENT
As part of the plan update process the City invited stakeholders to review and comment on the Public Review Draft of the LHMP. These stakeholders included neighboring jurisdictions, utility providers, the local school district, the Aliso Viejo homeowners’ association, local water districts, and County agencies. Information regarding this engagement opportunity can also be located in Appendix B of the document. All jurisdictions and stakeholders were invited via email, and/or direct communication via telephone from Aliso Viejo’s Senior Emergency Management Program Coordinator. The following is a list of those stakeholders invited to participate in the plan development process and review.

Vulnerable Populations Outreach
Signage was posted at all city facilities with information on both the Public Review LHMP and the Hazard Mitigation Survey. This included the Iglesia Park Community Center, which houses the Boys and Girls Club program for the surrounding neighborhood. Having the signage and information on the LHMP and feedback survey posted at the Iglesia Park Community Center was a focus that ensured this portion of the community is aware of the plan and the city’s request for feedback. This area is unique in that it is the only Census tract in the C ity that, according to the OC Health Care Agency’s Equity Map
, is “very underperforming” in the following areas: having internet access, having a broadband subscription, and having one or more types of computing devices in the home. It was important that the City didn’t solely rely on online sources to publicize LHMP process and plan. The information was also placed at Aliso Viejo Ranch, which the City felt was important because the facility hosts events, classes, and community programs for residents of varying ages. Over 1000 people visit the Aliso Viejo Ranch each month.
Future Outreach Opportunities
Recognizing that other vulnerable populations may exist in the City, this plan focused on the populations identified by OC Health Care Agency’s Equity Map. C ontinued outreach that occurs 75 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
8 during implementation and future updates will continue to refer to this resource to help identify vulnerable populations and key issues affecting their vulnerability.
Community Meetings and Events/Public Engagement Opportunities The City regularly conducts community meetings and events intended to provide useful information to participants/ attendees. During the planning process, three outreach meetings and events were held, where City staff discussed the plan and process currently underway and provided opportunities for feedback. Over 500 people attended these meetings and events. The following information provides dates for each meeting:
• Aliso Viejo City Council Meetings on Wednesday, May 17, 2023, and December 6, 2023
• Furry Friends Pet Fair on Saturday, September 9, 2023 • Health and Safety Fair on Saturday, November 4, 2023
ONLINE ENGAGEMENT
The City conducted a variety of online engagement activities that support the hazard mitigation planning process. The following are key activities conducted:
LHMP Project Webpage
The City created a page on the City’s website dedicated to the Local Hazard Mitigation Plan development to reach a broad audience and increase public engagement and participation. The webpage is a simple, one stop location for community members to learn about the LHMP. The webpage explains what an LHMP is, why the City should have one, how it is developed, and how the public can participate in the planning process including a link to the LHMP survey described in the next section. The webpage can be found at www.AVcity.org/LHMP .
Online Survey
The City released an online survey to community members to gather feedback on the planning process and hazards of concern. The survey was advertised via the City and Orange County Sheriff’s Department Aliso Viejo Police Services social media channels; on the city website; via the City’s online newsletter; in the City’s printed brochure that was mailed to every residence in the City; via local schools and churches; posted at City facilities in English and Spanish; and at community events and meetings.
At the time of the Public Review Draft release, the City had received a total of 45 responses from community members and stakeholders during the survey period. Responses were received from all areas within Aliso Viejo, ensuring that geographically, the entire City was represented. Based on these responses, the following information was shared with the City:
• Nearly 56% of respondents live in Aliso Viejo, with an additional 24 % that both love and work in Aliso Viejo.
• Approximately 18% of respondents have been impacted by a natural hazard in their residence.
• The top three hazards of concern for respondents include: Wild land and Urban Fires, Severe Weather Hazards (Severe Wind, Drought, and Winter Storms), Seismic Hazards (Seismic Shaking and Liquefaction) . These responses confirmed that the concerns identified by City staff during the planning process were similar to residents that responded.
• Approximately 76% of respondents are very or somewhat concerned that climate change will create new or worsen existing hazard conditions.
76 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
9 • 31% of respondents are familiar with the special needs of their neighbors in the event of a disaster situation (special needs may include limited mobility, severe medical conditions, and memory impairments).
• Approximately 16% of respondents are members of the Aliso Viejo Community Emergency Response Team (CERT). 42% of respondents indicated that they are not members of the CERT Team, but would like to learn more about CERT.
As part of the outreach strategy, a QR code was created that could be used on promotional materials and handouts at fairs and booths used by City staff at community events. This QR Code provided quick access to the City's Online Survey.
The results from the survey were provided to the HMPC. The data was then analyzed, reviewed, and incorporated by the HMPC within the LHMP content.
The data provided by the survey presented unique local insight into hazard concerns, and assessed the overall opinion and perception of the public when it comes to the hazards that affect Aliso Viejo. The full hazard mitigation survey results and copies of all materials used for public outreach, are provided within Appendix B of the LHMP, including the survey questions and answers.
Social Media Outreach
The City promoted and provided information on both the Hazard Mitigation Survey and the LHMP Public Review Draft on multiple social media platforms. • The City of Aliso Viejo eNews subscribers (total of 3,279 subscribers) were provided information on multiple occasions.
• City of Aliso Viejo X (formerly known as Twitter) account has 7,758 followers. • City of Aliso Viejo Instagram account with 7,965 followers. • City of Aliso Viejo – Local Government Group Facebook account with 7,800 followers. • City of Aliso Viejo Nextdoor account which received 240 impressions (views/interactions) on its post
PUBLIC REVIEW DRAFT
On November 15, 2023, the City released a draft copy of the LHMP for public review and comment. The document was posted electronically on the City’s LHMP Project website and social media accounts. The release also included flyers at City facilities, released on OCSD Aliso Viejo Police Services social media accounts, and promoted at the Health and Safety Fair on November 4th. The City also distributed notifications about the public review draft via local schools and churches as well as the Chamber of Commerce business distribution list. The Public Review Draft period extended from November 15, 2023, through December 15, 2023.
PLAN REVISION AND ADOPTION
The City received only 1 response from a stakeholder on the plan during the public review period from November 15, 2023, through December 15, 2023, however the response didn’t require any edits or modifications to the plan content or major revisions. Following public comment, the City submitted the plan to Cal OES and FEMA, initiating their review process. Upon completing this review process, City staff transmitted the final plan to the City Council for final adoption. The Aliso Viejo City Council adopted the final LHMP on [Month, Day, 2024] . Appendix C contains a copy of the adoption resolution.

11 CHAPTER 2 – COMMUNITY PROFILE
The Community Profile section of the LHMP describes Aliso Viejo, including information about the community's physical setting, history, economy and demographics, current and future land uses, and key infrastructure. The Community Profile helps establish the baseline conditions in Aliso Viejo, which informs the development of the hazard mitigation strategies and actions in Chapter 5.
SETTING AND LOCATION
Aliso Viejo is a city located in southern Orange County California. The city is roughly bisected by Highway 73 with the cities of Laguna Beach bo rdering to the west, Laguna Woods to the north, Laguna Hills to the east, and Laguna Niguel and unincorporated County lands to the south. A primarily residential community, Aliso Viejo offers a wide variety of housing opportunities and has adequate schools, employment, parks and open space for recreation, and shopping.
The city experiences an average of 281 sunny days per year, compared to a national average of 205 days. There is rarely any recorded snowfall in Aliso Viejo, ranking it as one of the least snowy places in California. Aliso Viejo experiences about 13.2 inches of rain every year, compared to the national average of 38 inches per year.
3 The average temperature in Aliso Viejo ranges
between 70-85°F for most of the year. Like most of Southern California, Summers in Aliso Viejo are hotter on average.
HISTORY
The first known inhabitants of the Aliso Viejo area were members of the Juaneno and Acjemem Native American tribes. The Spaniards founded nearby Mission San Juan Capistrano in 1776, and ruled the region until 1782, when California became Mexican territory and was divided into several large ranchos. In 1842, the Mexican government granted the land to Juan Avila, and in 1848 the Guadalupe Hidalgo treaty was signed, making California a territory of the United States.
In 1890, the Moulton family took title to approximately 22,000 acres of land, naming the area Moulton Ranch.
Over the years, portions of the ranch were sold and became Laguna Hills, Laguna Niguel, and Leisure World (now part of Laguna Woods). Development of the private retirement community of Leisure World began in the early 1960s on 2,095 acres of the Moulton Ranch just north of the current City. In 1976, the Mission Viejo Company purchased the last remaining 6,600 acres of the Moulton Ranch, located adjacent to Laguna Beach, just west of Mission Viejo. The Company then drew up plans for a 20,000-unit master-planned community named Aliso Viejo. Aliso Viejo means "Old Sycamore" in Spanish. Alder trees continue to dot the creek beds of Aliso Creek, which runs through the city.
The master plan was designed to meet the needs of a broad range of new home buyers, but also called for a delicate balance of retail and open space, resulting in a community where people really can live, work, and play in the same place. In 1979, the County of Orange approved the Aliso Viejo Planned Community development plan, and the first residential units were offered for sale in March 1982. The first residents moved in that November.
In February of 1995, a Self-Governance Subcommittee of the Governmental Affairs committee of the Aliso Viejo Community Association (AVCA) began pushing to make Aliso Viejo a city. AVCA is one of the first community-wide property owners' associations of its kind in California, operating
3 “Best Places to Live”, 2022, https://www.bestplaces.net/climate/city/california/Aliso_viejo 79 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
12 in many ways like a city government, but without the authority and ability to provide municipal services. AVCA's function is to oversee the many parks, slopes, and some open space areas that are funded through residential and commercial property assessments. In October 1997, the Self- Governance Subcommittee broke away from AVCA and became the Aliso Viejo Cityhood 2000.
The goal of this organization was to incorporate the area and form a city.
In March 1999, Aliso Viejo Cityhood 2000 kicked off a petition drive to put the question of incorporation to a community vote. In March 2001, voters went to the polls and chose to make Aliso Viejo the 34th city in Orange County. The City of Aliso Viejo officially incorporated on July 1, 2001, and established a 5-member City Council. Residents and community leaders gathered that day under tents and along the steps of Grand Park's amphitheater for the inaugural City Council meeting.
MINERALS AND SOILS
The characteristics of the minerals and soils present in the City of Aliso Viejo indicate the potential types of hazards that may occur . Rock hardness and soil characteristics can determine whether an area will be prone to geologic hazards such as earthquakes, liquefaction, and landslides. Soils within Aliso Viejo consist of Sorrento-Mocha and Alo- Bosanko associations, which are generally well drained with moderately rapid permeability. Slopes in the City are generally in a north-south direction with some portions greater than 30 percent. It is noted that some liquefaction potential exists along the creek beds where there is no existing or planned development.
There are no unique qualities associated with geological composition in the city . There are no known landfills or alluvial collection points. The great majority of the developed land in the city has been mass graded in the past 30 years and areas of potential landslides have been stabilized through removal and engineering fill. There are relatively small areas in the Northwest quadrant of the city, which appear to have some non-substantive shallow instability due to quality control problems during mass grading. Understanding the geologic characteristics of Aliso Viejo is an important step in hazard mitigation and avoiding at-risk development.
DEMOGRAPHICS
The data used in this section comes from the most comprehensive American Community Survey 2016 - 2021(ACS), administered by the United States Census Bureau (U.S. Census) completed in 2022, and the California Department of Finance (DOF). Based on this dataset, Aliso Viejo’s projected population is 51,943, with a median age of 37.4. This median age is approximately 1.8 years younger than the average median age in Orange County (39.2). The percentage of children under the age of 10 is slightly higher at 14.7% when compared to the rest of Orange County, which 11.2%. The percentage of senior residents (aged 65 and older) in the city is 7% lower than the rest of Orange County. Aliso Viejo residents have a higher median income than the rest of Orange County. In addition, a slightly lower proportion of Aliso Viejo’s residents rent their homes (43.1%) than the rest of Orange County residents (43.5%).
Table 2-1 identifies the basic demographics for Aliso Viejo and Orange County according to the 2021 ACS 5-year projections. Note that these statistics may vary from the demographic information used in Chapter 4, Threat Profiles , as that data set comes directly from ESRI’s Business Analyst Tool.
In terms of its racial and ethnic composition, Aliso Viejo is a white-majority city, with 65.0% of all Aliso Viejo residents identifying as white. According to the ACS, this population makeup is similar to Orange County as a region, with some variations in the overall percentages. Table 2-2 shows the racial and ethnic composition of all groups in the Aliso Viejo and Orange County region.
Aliso Viejo residents have attained higher education levels in comparison to Orange County. For example, a higher percentage of the city’s population has earned a bachelor’s degree (34.9%) 80 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
13 compared to the rest of Orange County (26.6%). Similarly, a higher percentage of the city has attained a graduate or professional degree (21.3%) as compared to Orange County (15.5%).
Other categories also differ, such as a lower percentage of people not having education past ninth grade and a lower percentage of people not having graduated high school. However, a lower percentage of the city’s population has a higher High school graduate or equivalent level of education than Orange County. Table 2-3 shows all levels of educational attainment of residents 25 years of age or older in both Aliso Viejo and Orange County, according to the American Community Survey as of 2021.
Aliso Viejo has a wide range of non-English languages spoken at home among its residents, with varying proficiency levels. Generally, Spanish is the second most spoken language in Aliso Viejo, with approximately 34.7% that speak English less than “very well.” Asian and Pacific Islander languages are the third most-spoken languages in Aliso Viejo, with slightly over 45.7% that speak English less than “very well.” This is similar to populations in Orange County, where slightly over 37% of Spanish language speakers speak English less than “very well.” According to the ACS, Table 2-4 shows the most spoken languages and the levels of fluency among speakers aged five years and older in Aliso Viejo and Orange County.

16 DEVELOPMENT TRENDS
Aliso Viejo is located within a dense part of southern Orange County that has experienced significant growth and development over the past 50 years. Aliso Viejo was officially incorporated in 2001, the population at the time was 40,166. The city's population has grown by approximately 11,777 residents (approximately 22.7%), to 51,943 residents in the past 20 years. While growth within the city is anticipated to increase, the number of viable parcels to build on continues to shrink as the community approaches buildout.
According to the 2021-2029 City of Aliso Viejo Housing Element, the city has a state mandated regional housing needs allocation (RHNA), residential development requirement of 1,195 units.
The RHNA process is the part of Housing Element Law used to determine how many new homes, and the affordability of those homes, each local government must plan for in its Housing Element.
Currently the City does not have an adequate number of residential sites that are appropriately zoned to accommodate all income categories of the RHNA requirement. To accommodate all its RHNA requirements the City has developed specific action programs to create the space needed for development. This will include amendments to the Aliso Viejo General Plan and zoning regulations to accommodate 100% of the shortfall in residential units. The city has identified candidate sites to potentially be rezoned and facilitate the development of affordable multi-family housing, by supporting funding applications, allocating funds from the Affordable Housing Trust Fund, and/or approving modifications to development standards. The city has other strategies outlined in the Housing Programs section of the 2021-2029 Housing Element, which can be accessed here
. Figure 2-1 identifies the current land uses designated within the City.
VULNERABILITY AND RISK REDUCTION
All new development occurring in the amended zoning areas will provide hazard vulnerability and risk reduction for the city. This reduction will occur due to the anticipated improvements and investments implemented in the older parts of the City because of these amendments to the General Plan and zoning regulations. In addition, the new developments that will be built will comply with the most up-to-date building codes and use the latest techniques, further reducing vulnerabilities throughout the city.
MAJOR COMMUNITY COMPONENTS
OPEN SPACE AND CITY PARKS
The City of Aliso Viejo prides itself on its beautiful scenery, open spaces, and 23 immaculate arks.
The City owns and manages both Vista Park as well as Iglesia Community Center and Park. The 21 other parks are managed by the Aliso Viejo Community Association (AVCA), whom is also responsible for approximately 600 acres of landscape within the community.
Aliso Viejo Ranch
In the spring of 2019, the Aliso Viejo City Council approved the construction contract for the city’s Aliso Viejo Ranch plan, paving the way for an historic project on the last remaining parcel of the 22,000-acre Moulton Ranch. The multi -disciplinary Aliso Viejo Ranch project preserves and restores historically significant buildings, artifacts, and farming implements from the 1800s and highlights the importance of the agricultural past of Orange County, the state of California and Western United States while demonstrating the future of sustainable agriculture and aquaponics.
A long time in the making, this unique plan includes the rehabilitation and adaptive reuse of the existing barn and bunkhouse along with a working farm with fruit and nut tree orchards, raised - bed vegetable gardens and several fishponds . The locally sourced food grown onsite will be donated – at no cost – to food banks and will provide farm -to-table food for school culinary programs and community classes and functions. The site will feature hands -on community educational programs on sustainable farming operations and will provide an opportunity for onsite 84 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
17 FIGURE 2-1: ALISO VIEJO LAND USE POLICY MAP
85 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
18 STEM, biological science, horticultural and urban educational classes and community programs, farm-to-table dinners, and special events. It will showcase Orange County’s development – from its agricultural roots to becoming the world’s 45th largest economy – and highlights the agricultural history of the United States.
Aliso and Wood Canyon Wilderness Park
The Aliso and Wood Canyon Wilderness Park is located partially within the City, as well as the neighboring communities of Laguna Niguel, Laguna Hills, Laguna Beach, and Dana Point. The park is approximately 4,500 acres of wilderness and natural open space land. Originally, part of the Juaneno or Acajchemem tribal land, it later was owned by Don Juan Avila, Louis Moulton, The Mission Viejo Company and now is under the jurisdiction of OC Parks. Within the park lands are mature oaks, sycamores, and elderberry trees, two year round streams and more than 30 miles of official trails. Many rare and endangered plants and animals make this park their home.
This park is designated as a wildlife sanctuary. Located within the state responsibility area (SRA) and under the jurisdiction of CalFire, the parks are considered to be in a fire hazard severity zone.
This is important as wildfire can spread from the park into the cities in which the park is located.
INFRASTRUCTURE ASSESSMENT
Infrastructure plays a vital role in mitigating the effects of hazard events. When infrastructure fails, it can exacerbate the effects of a hazard event or create complications for rescue workers trying to reach victims. For example, fallen utility poles resulting from strong winds or seismic activity can obstruct roadways and prevent emergency vehicles from reaching affected areas . The following are Aliso Viejo's electrical, gas, water and wastewater, and infrastructure transportation networks.
ELECTRICITY SERVICE
Electricity is provided to the city by both Southern California Edison (SCE) for residents and businesses west of Alicia Parkway, and by San Diego Gas & Electric (SDG&E) for residents and businesses east of Alicia Parkway . Both companies’ source electricity from power plants throughout California and neighboring states and deliver it through a network of large-scale power lines and substations. They are committed to delivering power reliably every day of the year, even during unusual events like heat waves. The threat of wildfires in California is real and growing.
One critical tool used to prevent wildfires is the Public Safety Power Shutoff (PSPS) circuits, in which power providers may temporarily shut off power to circuits during dangerous weather conditions to prevent their electric system from becoming a source of ignition, resulting in a wildfire. These safety shutoffs are a measure of last resort for keeping residents and the community safe. There is one PSPS circuit that can affect the flow of power to a section of the city, fortunately it has not been required to activate resulting in a loss of power to the city.
NATURAL GAS
The Southern California Gas Company (SoCalGas) provides natural gas to Aliso Viejo and surrounding jurisdictions . To ensure sufficient natural gas trans mission throughout the region, SoCalGas owns and operates trans mission lines throughout Orange County. If these lines are damaged, there is potential to interrupt the flow and delivery of natural gas throughout the region.
Additionally, natural gas ignites easily . Any rupture in a trans mission line could cause additional damage to properties in the vicinity of the leak due to fire from the escaped natural gas. The presence of this infrastructure creates unique challenges for the city from an emergency management perspective. The inclusion of hazards associated with damage to this infrastructure is an important element of an effective response to future incidents involving natural gas use and transmission.
86 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
19 WATER SERVICE
Water for City residents is supplied by the Moulton-Niguel Water District (MNWD), which serves all the city except for the Via Iglesia area, and the El Toro Water District (ETWD), which serves the Via Iglesia area. The two districts treat and distribute water purchased from the Metropolitan Water District, which imports water from northern California and the Colorado River. As with sewer lines, water trans mission, pumping, and storage facilities are expanded as necessary to accommodate future growth. Domestic water supply is not expected to limit development during the planning period.
WASTEWATER TREATMENT
Sewage collection and treatment in Aliso Viejo is provided by the S outh Orange County Wastewater Authority (SOCWA). SOCWA was created on July 1, 2001, to facilitate and manage the collection, transmission, treatment, and disposal of wastewater for more than 500,000 homes and businesses across South Orange County. SOCWA also manages production of recycled water for irrigation and commercial uses, which saves approximately 1.6 billion gallons of domestic water each year that otherwise would be used for those purposes, which is equivalent to 16,259-acre feet of water. SOCWA is a Joint Powers Authority with ten member agencies, consisting of local retail water agencies and cities that provide water to their residents. It operates three treatment plants and two ocean outfalls, in addition to multiple programs to meet the needs of its member agencies and the requirements of the Clean Water Act and applicable National Pollutant Discharge Elimination System (NPDES) permits.
STORM WATER DRAINAGE
The City has developed a Stormwater Program, which is a comprehensive pollution prevention program under its local implementation plan (LIP). Since its incorporation in 2001, the City has cooperated with the County of Orange, the Orange County Flood Control District, and the other cities in Orange County (collectively the Orange County Stormwater Program or “Program”). The result of this cooperation has been the development of a series of model stormwater program elements that comprise the county -wide Drainage Area Management Plan (DAMP). The City’s goal is to continue to educate the community on ways to protect and preserve our environment by eliminating urban runoff and implementing more “eco-friendly” lifestyles through an array of programs and special events.
TRANSPORTATION SYSTEM
Private automobiles are the dominant means of transportation in Southern California and in the City of Aliso Viejo. However, the City of Aliso Viejo meets its public transportation needs through a mixture of a regional transit system (OCTA) and various city contracted transportation services for seniors and access and functional needs patrons. According to the U.S. Census Bureau, about 92% of employed Aliso Viejo residents worked in Orange County, and approximately 29 % of all workers were employed within the city limits. City infrastructure accommodates regional through traffic originating in other communities on the San Joaquin Hills Transportation Corridor (SR -73) and other major regional parkways. In addition, a healthy local economy depends on the ability of businesses to move their goods, and the ability of employees living throughout the region to get to and from employment locations within the city.

20 CHAPTER 3 – HAZARD ASSESSMENT
HAZARD PROFILES
This chapter discusses the types of hazards that might reasonably occur in Aliso Viejo. It describes these hazards and how they are measured, where they may occur, a history of these hazards in and around the city , and the future risk they pose. The discussion of future risks includes changes to the frequency, intensity, and/or location of these hazards due to climate change. This chapter also discusses how the HMPC selected and prioritized this Plan's hazards.
HAZARD IDENTIFICATION
FEMA guidance identifies several hazards that communities should evaluate for inclusion in a hazard mitigation plan. Communities may also consider additional hazards for their plans. The HMPC reviewed an extensive list of hazards and excluded those that do not pose a significant threat to Aliso Viejo. Table 3-1 lists the hazards considered and explains the reasoning for inclusion/exclusion. For context, this table also shows if a hazard is recommended for consideration by FEMA, if it is included in the 2018 California State Hazard Mitigation Plan (SHMP), and if it is included in the Orange County Hazard Mitigation Plan (OC HMP). This table does not include all potential impacts; the table is based upon FEMA and State guidance and the most probable impacts within Aliso Viejo. As a result, some hazards like war or foreign invasion are better addressed at the Federal level.
TABLE 3-1: HAZARD EVALUATION FOR ALISO VIEJO LHMP
Hazard Recommended
for
Consideration
Included
in this
LHMP?
Reason for Inclusion or Exclusion
Agricultural
Pests
SHMP No Aliso Viejo has minimal agricultural uses within the city that contribute to the economy.
Concerns regarding agricultural pests are not a
significant concern citywide.
Air Pollution SHMP No Air pollution is a state and regional issue that is addressed through plans and regulations
administered by the South Coast Air Quality
Management District and/or California Air
Resources Board. Since the City has little
control over regulating air quality, this hazard
was not included.
Aircraft Incident SHMP No The city is located approximately 12 miles from John Wayne Airport. Given the distance and
lack of history associated with this hazard in the
city, it was determined that this hazard should
not be included in the plan.
Aquatic Invasive
Species
SHMP No There are no lakes within the City that could be impacted by invasive aquatic species.
Avalanche FEMA guidance
SHMP
No There is no potential for avalanches to occur
within the city.
Civil Disturbance
or Riot
SHMP No The city does not contain any major tourist
destinations or facilities that allow large crowds
of people to assemble or a history of civil
disturbances.
Climate Change SHMP
OC HMP
Yes Climate change is a concern identified by the
HMPC and has been included within each
hazard profile, where relevant.
88 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
21 Coastal Flooding
and Storm
FEMA guidance
SHMP
No Based on its distance from the coast, coastal
flooding and storms are not a concern for the
city.
Cyber Threats SHMP Yes The growing threat of cyber security and data breaches has increasingly become a potential
hazard of concern for cities.
Dam Failure FEMA guidance
SHMP
OC HMP
No There are no dams or reservoirs that would
affect the city in the event of failure. Given the
lack of this potential, the HMPC did not identify
dam failure as a hazard of concern.
Drought SHMP
OC HMP
No Droughts are a recurring hazard in Aliso Viejo
and Southern California and can affect city
water supplies. The City’s water supply comes
from multiple water districts, which purchase
water from other sources/purveyors. Drought is
addressed in the Urban Water Management
Plans and Hazard Mitigation Plans of both
water districts and supported by the city. The
Aliso Viejo City municipal code chapter 7.30
outlines the water efficient landscape
regulations put in place by the city to aid in
drought mitigation. As the water supply for the
city is out of their control, and current policies
are in place by the both the city and the water
districts’, drought was not identified as a hazard
that should be addressed in the City’s Hazard
Mitigation Plan.
Energy Shortage SHMP No Aliso Viejo’s electrical power is provided by Southern California Edison, and San Diego
Electric and Gas Company, which both have a
long history of reliability, and therefore the
HMPC decided that this is not a concern for the
city.
Epidemic,
Pandemic,
Vector-Borne
Disease
SHMP No Although epidemic, pandemic, and vector-borne
diseases can occur in the City, there are no
major tourist attractions that could be point
sources for major infection events or historic
issues with this type of hazard.
Erosion FEMA guidance
SHMP
No The city has not experienced major cases of
erosion; therefore, the HMPC decided it was not
a concern for the city.
Expansive Soil FEMA guidance No The City does not experience a significant issue with expansive soils.
Extreme Cold FEMA guidance
SHMP
No Temperatures in Aliso Viejo do not fall to a level
that would be considered a danger to public
safety.
Extreme Heat FEMA guidance
SHMP
No Extreme heat conditions have occurred in the
city and are expected to be a future recurring
issue. However, the City did not identify this as
a concern due to the relatively newer housing
stock and higher adaptive capacity of residents
within the City.
Fault Rupture FEMA guidance
SHMP
OC HMP
No There are no known active faults that could
rupture within the city.
89 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
22 Flooding FEMA guidance
SHMP
Yes The city experiences periods of heavy rainfall
between October and April, which combined
with the hillside topography within the
community, could cause flooding in key areas of
the city.
Fracking SHMP No Fracking does not occur in Aliso Viejo.
Hail FEMA guidance No Hail that is severe enough to pose a threat to people and property is not a concern identified
by the HMPC.
Hazardous
Materials release
SHMP Yes The threat posed by hazardous materials
release incidents occurring is low, given the
presence of commercial centers and
businesses however, the potential does exist.
This is a hazard of concern for the city.
Hurricane FEMA guidance
SHMP
No Hurricanes do not occur with any frequency in
Aliso Viejo and are not a concern for the City.
Infrastructure
Failure
SHMP Yes Infrastructure failure poses a threat to people and property in Aliso Viejo. While not a stand-
alone hazard of concern, it is recognized and is
discussed as a function of other hazards.
Landslide FEMA guidance
SHMP
Yes Areas of the city have varying degrees of
landslide potential. As a result, the HMPC
identified this as a hazard of concern within the
plan.
Levee Failure SHMP No The HMPC identified flooding as a hazard of concern, given the lack of levees within the city
however, this was not identified as a hazard of
concern.
Lightning FEMA guidance No Although lightning occasionally occurs in Aliso Viejo, it does not pose a significant threat to
people or property.
Liquefaction FEMA guidance
SHMP
OC HMP
Yes According to the California Geological Survey,
portions of the city are located within
liquefaction-prone areas. Based on this
mapping, the HMPC identified liquefaction as a
hazard of concern.
Methane-
containing Soils
OC HMP No The city does not have a history of incidents involving methane-containing soils and is not a
hazard of concern identified by the HMPC.
Natural Gas
Pipeline Hazards
SHMP No Natural gas transmission pipelines are located
within the city and could pose a danger to
people and property if they breach and release
their contents into the community. However, the
HMPC did not identify this as a hazard of
concern to the city.
Oil Spills SHMP No This is not a hazard of concern as there is no oil drilling occurring within the city.
Power Failure SHMP No Aliso Viejo’s electrical power is provided by Southern California Edison and San Diego Gas
and Electric which has a long history of
reliability, and therefore the HMPC decided that
this is not a concern for the city. PSPS circuits
are discussed in the wildfire section as a
90 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
23 potential source of power interruption during
wildfire and high wind conditions.
Radiological
Accidents
SHMP No There are no known major radiation sources in
Aliso Viejo or the immediate surrounding area
that could seriously threaten the community.
Sea-level Rise FEMA guidance
SHMP
No Aliso Viejo is not located within close proximity
to the ocean.
Seiche FEMA guidance
SHMP
No There are no major bodies of water in Aliso
Viejo that could be subjected to seiche,
therefore this hazard was not deemed a
concern by the HMPC.
Seismic Shaking FEMA guidance
SHMP
OC HMP
Yes Aliso Viejo is in a seismically active area where
shaking can be severe enough to damage
property or cause loss of life. For this reason,
the HMPC determined it should be addressed in
this plan.
Severe Wind FEMA guidance Yes Windstorms are a common occurrence within the city and southern California. This hazard is
included in the Severe Weather profile, referred
to as windstorms. Severe wind events typically
occur during Santa Ana wind conditions.
Severe Weather

FEMA guidance
SHMP
OC HMP
Yes Severe Weather includes discussions regarding
severe wind (windstorms), and rain, which are
weather-related hazards that are most common
in Aliso Viejo and a concern for the city.
Storm Surge FEMA guidance No The HMPC did not identify this as a hazard of concern since the city is not located near the
California coastline.
Subsidence FEMA guidance No The HMPC did not identify subsidence as a hazard of concern.
Mass-Casualty
Incident
(Terrorism)
SHMP Yes The HMPC identified mass-casualty incidents
and terrorism as potential hazards of concern.
This hazard is addressed in the Human-Caused
Hazards section.
Thunderstorm SHMP No Thunderstorms that cause damage and endanger public safety are rare in this part of
Southern California.
Tornadoes FEMA guidance
SHMP
No Tornadoes were not considered a hazard that
could impact the city regularly and were not
included in this LHMP.
Transportation
Accidents
SHMP No Given the lack of major transportation routes
through the city, the HMPC did not identify this
hazard as a concern for this plan.
Tree Mortality SHMP No While the city’s tree inventory is a significant asset at risk, it was not identified as a hazard of
concern by the HMPC.
Tsunami FEMA guidance
SHMP
No The HMPC did not identify tsunamis as a
hazard of concern since the city is not located
near the California coastline.
Urban Fire SHMP
OC HMP
Yes The HMPC identified urban fires as a risk to
property and life in Aliso Viejo, and therefore
was included in this plan as a part of the wildfire
hazard discussion.
91 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
24 After hazard evaluation and the organizational changes were made by the HMPC , this Plan discusses eight broad hazard types with their respective sub-categories, including climate change, which is discussed in each hazard profile:
Hazard Type Sub-Categories
Earthquake Seismic Shaking, Liquefaction
Wildfire/Urban Fire
Human Caused Hazards Cyber Threat/Terrorism, Haz Mat Release Severe Weather Windstorms, Winter/Coastal Storms
Landslide
Flood
Climate Change Discussed in each relevant Hazard Profile
HAZARD SCORING AND PRIORITIZATION
The HMPC followed FEMA guidance for hazard mitigation plans and prioritized each of the eight hazards and their respective subcategories. In the initial step, it assigned a score of 1 to 4 for each of the hazards for the following criteria:
• Probability: The likelihood that the hazard will occur in Aliso Viejo in the future. • Magnitude/Severity: The severity of the direct damage of the hazard to Aliso Viejo. • Warning Time: T he time the city has before a disaster event/hazard impacts Aliso Viejo.
• Duration: The time that the disaster event will affect Aliso Viejo.
The HMPC assigned a weighting value to each criterion, giving a higher weight to the criteria deemed more important and multiplied the score for each criterion by weighing the factor in determining the overall score for each criterion.
FEMA recommended the weighting values:
• Probability: 45%
• Magnitude/Severity: 30%
• Warning Time:
15%
• Duration: 10%
Table 3-2 shows the Criterion Scoring used to assign a score for each criterion.
Volcano SHMP No There are no volcanoes near Aliso Viejo to pose a reasonable threat.
Wildfire FEMA guidance
SHMP
Yes The HMPC identified wildfire as a major threat
to the city, and therefore was included in this
plan.
92 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
25 After calculating the total impact score for each hazard (sum of the probability, magnitude/severity, warning time, and duration). FEMA guidance recommends multiplying the total impact score by the overall probability to determine the final score for each hazard.

27 EARTHQUAKE HAZARDS (SEISMIC SHAKING, LIQUEFACTION)
DESCRIPTION
An earthquake is a sudden motion or trembling 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 can cause massive damage and extensive casualties after just a few seconds. 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. This sudden discharge of energy into the crust can lead to rupturing of land that sits on top of fault lines, liquefaction in areas with wet soil, or landslides in hilly or mountainous areas.
Seismic Shaking
Seismic shaking is the motion felt on the earth’s surface caused by an earthquake. In most cases, earthquakes are not powerful enough to feel the shaking. However, particularly powerful earthquakes can generate significant shaking, causing widespread destruction resulting in property damage.
Liquefaction
Occurs when seismic energy is released within an area with low-density, fine grain soil, like sand or silt, which is saturated with water. Liquefaction takes place when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking.5 During liquefaction events, the liquified soil can lose most of its stability which can cause damage to buildings and infrastructure built upon it. In severe cases, some buildings may completely collapse. Pipelines or other utility lines running through a liquefaction zone can be breached during a liquefaction event, potentially leading to flooding or the release of hazardous materials.
LOCATION AND EXTENT
Earthquakes are considered a major threat to the City of Aliso Viejo due to the proximity of several fault zones, notably the San Andreas Fault Zone, the San Joaquin Hills Fault Zone, the Newport- Inglewood Fault Zone, Elsinore Fault, and the Puente Hills Fault. Aliso Viejo has two known faults, the Aliso and the Cristianitos, both of which are considered to be inactive. However, should an earthquake occur along one of these faults it could be particularly damaging to the City. There are no known active faults to pass through the City. The closest faults to the city are the Elsinore, Whittier, and the Newport-Inglewood Faults. A significant earthquake along one of the major faults could cause substantial casualties, extensive damage, and other threats to life and property. The shaking of the ground can also damage or destroy underground utilities or pipelines, potentially leading to releases of hazardous materials and flooding if water lines are breached.
Depending on the magnitude and duration of an earthquake along one of the faults in the region, Aliso Viejo can expect to see varying degrees of damage citywide. As part of a master planned community, the topography of the city means there are areas of the community constructed on slopes meaning these areas may be subject to earthquake induced landslides (reference the landslide hazard profile for further discussion).
5 USGS Definition of Liquefaction
95 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
28 Seismic Shaking
Southern California, including Aliso Viejo, is a highly seismic area due to the major faults that run through the region and is subject to experiencing seismic shaking. The intensity of seismic shaking is usually measured with the Modified Mercalli Intensity (MMI) scale, which is based on the amount of observed damage. The MMI scale has replaced the Richter scale, which is no longer used since it loses effectiveness when measuring larger earthquakes. Since the degree of shaking, and consequently damage, generally decreases as the seismic energy travels further away from the fault rupture’s point of origin, different sections of a city or region can report different MMI measurements in different locations. The MMI scale uses Roman numerals on a 12-point scale to measure each degree of shaking intensity. Table 3-4 shows the MMI scale, while Table 3-5 lists the earthquake faults that can impact the City.
Another scale for measuring seismic shaking is the moment magnitude scale (MMS, denoted Mw or simply M). The MMS measures the energy released by the fault rupture beginning at 1.0 and increasing as the earthquake's energy grows. The MMS is a logarithmic scale, meaning that the difference between numbers on the scale multiplies as they increase. An earthquake with 5.0 M is approximately 1.4 times greater than 4.9 M, 32 times greater than 4.0 M, and 1,000 times greater than 3.0 M.
Seismic shaking can also be measured in relationship to the force of Earth’s gravity (g), or percent g. This method is useful for geographically displaying areas of seismic shaking potential. Percent g is computed by determining the acceleration of the earthquake’s motion relative to the force of gravity. The acceleration of gravity is 980 centimeters per second, so if, for example, an earthquake’s acceleration is measured at 765 centimeters per second, the shaking is modeled as 765/980, or .781 g (78.1% g). Figure 3-1 shows the seismic hazard zones and associated faults in and around Aliso Viejo, while Figure 3-2 shows the seismic shaking potential in the City.
TABLE 3-4: MODIFIED MERCALLI INTENSITY SCALE
Rating Intensity Description
I Instrumental Felt only by a very few people, under especially favorable conditions.
II Feeble Felt only by a few people at rest, especially on the upper floors of buildings.
III Slight Noticeable by people indoors, especially on upper floors, but not always recognized as an earthquake.
IV Moderate Felt by many indoors, and by some outdoors. Sleeping people may be awakened.
Dishes, windows, and doors are disturbed.
V Slightly strong Felt by nearly everyone, and many sleeping people are awakened. Some dishes and windows broken, and unstable objects overturned.

32 Liquefaction
Occurs when ground shaking causes wet granular soils to change from a solid state to a liquid state. This results in the loss of soil strength and the soil's ability to support weight. Buildings and their occupants are at risk when the ground can no longer support these structures. Liquefaction generally occurs during significant earthquake activity, and structures located on soils such as silt or sand may experience significant damage during an earthquake due to the instability of structural foundations and the moving earth. Many communities in Southern California are built on ancient river bottoms and have sandy soil. In some cases, this ground may be subject to liquefaction, depending on the depth of the water table. Figure 3-3 shows the liquefaction zones in Aliso Viejo as designated by the California Geological Survey.
Liquefaction zones are located along the eastern and western borders of the city. The liquefaction susceptible areas on the western border are located along the length of El Toro Rd (County Route S-18), which travels along a valley on its way towards the coast. While on the eastern border of the city the liquefaction susceptible areas are found primarily along the Aliso Creek watershed as it travels through the city on its course to the Pacific Ocean. Large portions of these areas are located in open space and parks, including the Aliso and Wood Canyons Wilderness Park. As seen in Figure 3-3, the liquefaction threat is generally located in these portions of the city, and the threat is ranked as having high liquefaction potential in these areas, while the rest of the city generally has a minimal liquefaction potential.
PAST EVENTS
Since seismologists started recording and measuring earthquakes, there have been tens of thousands of recorded earthquakes in Southern California, most with a magnitude below three.
No community in Southern California is beyond the reach of a damaging earthquake. Table 3-6 shows all earthquakes in Southern California with a magnitude of 5.0 or higher.

Seismic Shaking
Aliso Viejo has undoubtedly felt the shaking of
regional earthquakes , some stronger than others.
The nearest earthquake event to Aliso Viejo that
caused significant damage throughout the Southern
California region was the 1933 Long Beach
earthquake. The actual epicenter of the quake was in
the City of Huntington Beach; however, most of the
damage occurred in areas north of the epicenter. The
event caused more than $50 million in property
damage and resulted in the deaths of 120 people.
Most of the deaths and damage from the 1933 Long
Beach Earthquake occurred because of collapsing
unreinforced masonry buildings.
Other strong, regional earthquakes have occurred in
Southern California, but their epicenters have been so distant from Aliso Viejo that seismic shaking generated by the earthquake did not cause significant property damage or harm to the City. For example, the 2014 La Habra earthquake caused major damage in Fullerton, La Habra and Brea, though it was only considered to be light shaking in Aliso Viejo.
The most recent significant earthquake event affecting Southern California was the Northridge Earthquake's January 17, 1994. At 4:31 A.M. on Monday, January 17, a moderate but very damaging earthquake of 6.7 M struck the San Fernando Valley. In the following days and weeks, thousands of aftershocks occurred, causing additional damage to affected structures. Fifty-seven people were killed, and more than 1,500 people seriously injured. For days afterward, thousands of homes and businesses were without electricity; tens of thousands had no gas, and nearly Seismic shaking primarily affects unreinforced masonry
buildings, as seen here with this Long Beach middle school damaged by the 1933 Long Beach earthquake.

35 50,000 had little or no water. Approximately 15,000 structures were moderately to severely damaged, leaving thousands of people temporarily homeless; 66,500 buildings were inspected, nearly 4,000 were severely damaged, and over 11,000 were moderately damaged. Several collapsed bridges and overpasses created commuter havoc on the freeway system. Extensive damage was caused by ground shaking, but the earthquake triggered liquefaction, and dozens of fires also caused additional severe damage. This extremely strong ground motion in large portions of Orange County resulted in record economic losses. Table 3-7 shows significant earthquakes – magnitude 6.0 Mw or greater – that have occurred within 100 miles of Aliso Viejo since the beginning of the 20th century. Aliso Viejo, while not officially incorporated at the time, had no significant reported incidents of damage, authorities made disaster declarations in Orange County for the 1994 Northridge Earthquake and 1987 Whittier Narrows Earthquake.
Liquefaction
There is limited information available on the occurrence of past liquefaction events in Aliso Viejo.
Since these events occur in conjunction with strong earthquakes, the nearest and most recent liquefaction event would have occurred near the mouth of the San Gabriel River at Alamitos Bay because of the Long Beach Earthquake in 1933. It was reported that pavement buckled, cracks appeared in the ground, and “mud volcanoes” erupted in the Los Alamitos area. 6 TABLE 3-7: SIGNIFICANT EARTHQUAKES (6.0+ MW) WITHIN 100 MILES OF ALISO VIEJO Event Name Distance (Miles)* Magnitude

RISK OF FUTURE EVENTS
Seismic Shaking
Historical and geological records show that California has a long history of seismic events.
Southern California is probably best known for the San Andreas Fault, a 400-mile -long fault running from the Mexican border to a point offshore, west of San Francisco. Geologic studies show that over the past 1,400 to 1,500 years, large earthquakes have occurred at about 130-year intervals on the Southern San Andreas Fault. As the last large earthquake on the Southern San Andreas occurred in 1857, that section of the fault is considered a likely location for an earthquake within the next few decades. The Third Uniform California Earthquake Rupture Forecast (UCERF3) was released in 2015 and is the most recent assessment of the probability of a major

The U.S. Geological Survey scenarios show that the San Joaquin Fault could cause the strongest seismic shaking in Aliso Viejo, followed by San Andreas and the Newport-Inglewood faults. The more distant faults like the San Jacinto and San Andreas faults can produce more intense earthquakes but are less like to cause damage in Aliso Viejo due to their greater distance from the City. However, as noted in Table 3-8, the likelihood of a powerful earthquake occurring along the majority of these faults within the next 25 years is generally very low (excluding the San Andreas).
Liquefaction
Soil liquefaction is a seismically induced form of ground failure, which has been a significant cause of earthquake damage in southern California. During the 1971 San Fernando and 1994 Northridge earthquakes, significant damage to roads, utility pipelines, buildings, and other structures in the Los Angeles area was caused by liquefaction. Research and historical data indicate that loose, granular materials situated at depths of less than 50 feet with fine (silt and clay) contents of less than 30%, which are saturated by a relatively shallow groundwater table, are most susceptible to liquefaction. These geological and groundwater conditions exist in parts of southern California and Aliso Viejo, typically in valley regions, stream and river watersheds, and alluvial floodplains.
For liquefaction to occur, three general conditions must be met. The first condition – strong ground shaking of relatively long duration – can be expected to occur in the Aliso Viejo area because of an earthquake on any of the several active faults in the region. The second condition – loose, or unconsolidated, recently deposited sediments consisting primarily of silt and sand – occurs in a large portion of the valley floors and the larger canyon bottoms prevalent throughout Orange County. The third condition is water -saturated sediments within about 50 feet of the surface.
Liquefaction could occur but defining the precise likelihood isn’t possible. Refer to Table 3-8 for the probability of a major earthquake occurring in faults close to Aliso Viejo.
CLIMATE CHANGE CONSIDERATIONS
Seismic Shaking
There is no direct link between climate change and seismic activity, so climate change is not expected to cause any changes to the frequency or intensity of seismic shaking. Some research 104
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
37 indicates that climate change could result in “isostatic rebounds,” or a sudden upward movement of the crust because of reduced downward weight caused by glaciers. As glaciers are known to melt when global temperatures increase, climate change could indirectly lead to increased seismicity in Southern California.
7 Liquefaction
While climate change may not impact seismic shaking, it can directly impact liquefication. Climate change is anticipated to change the usual precipitation patterns in Southern California. Periods of both rain and drought are anticipated to become more intense and frequent. This means that more precipitation will likely occur during rainy periods, and drought is expected to last even longer. As a result, the water table along the creeks and canyons in Aliso Viejo could rise during intense periods of precipitation. Alternatively, a longer -lasting drought may lead to more groundwater withdrawal and could lower the water table. Therefore, climate change could potentially increase or decrease the risk of liquefaction in Aliso Viejo, depending on the circumstances. Prolonged droughts can decrease groundwater levels if additional water extraction occurs, decreasing the potential for liquefaction. While an increase in precipitation intensity and frequency could increase groundwater levels, potentially increasing liquefaction potential.
WILDLAND/URBAN FIRE
DESCRIPTION
Wildland Fire
Wildfires are fires that burn in largely undeveloped and natural areas, and they are a regular feature of ecosystems throughout California. These fires help to clear brush and debris from natural areas and are necessary for the health of many ecosystems and various species' life cycle. However, since the early twentieth century, the common practice was to suppress naturally occurring fires in wildland areas, allowing dry plant matter and other fuels to build up.
At the same time, human activity has caused changes in the buffer zone between urbanized and undeveloped areas, known as the wildland-urban interface (WUI). The more natural setting of a WUI can make these zones highly desirable places to live. In many parts of California, the WUIs have become developed, albeit at lower densities than fully urbanized areas. However, this development activity has brought more people into wildfire-prone areas. The availability of fuel and increasing encroachment into the WUI, together with a changing climate, have made wildfires among the most common and dangerous natural hazards in California.
Lightning, accidents, or arson can spark wildfires. The size and severity of any fire depend on fuel, weather conditions, and topography availability. However, wildfires in the WUI do not need to be large to be damaging. In Oakland, the 1991 Tunnel Fire was relatively small, only 1,600 acres, but it was one of California's deadliest and most destructive wildfires. 8 The flames from
wildfires create severe risks to property and lives. Smoke and other particulate matter from wildfires pose a health risk, even to those not near the blaze. Burned areas can be more susceptible to flooding and landslides because wildfires destroy the vegetation that helps slow down water runoff and hold slopes together.
9 The ground may repel water rather than absorb it
when faced with ash deposits. Due to the change in the landscape structure after a fire, repelled water can carry debris into water reservoirs.

38 Urban Fire
An urban fire is a fire that causes damage to buildings or infrastructure in an urbanized area. In some minor situations, the fire prompts the evacuation of the building’s occupants, and the fire is contained within a short amount of time by firefighting teams or the building’s fire suppression systems. In severe cases, the fire leads to the complete destruction of the building and can spread to other surrounding properties. Common causes of urban fires include stoves that are accidentally left on, short-circuited electrical equipment, or mishandling of household tools. Larger urban fires may be caused by breaches in gas pipelines, large transportation accidents, or downed electrical transmission wires. Fires may also be intentionally started by arsonists.
LOCATION AND EXTENT
Wildland Fire
Wildfires are not measured on a specific scale and are usually classified by size (e.g., acres burned) or impact (buildings destroyed or damaged, injuries or deaths, cost of damage, etc.). The California Department of Forestry and Fire Protection (Cal Fire) defines the wildfire hazard zones on a three-tier scale of fire hazard severity zones (FHSZs): very high, high, and moderate. These zone classifications do not correspond to a specific risk or intensity of fire but are qualitative terms that consider many factors. Fire-prone areas are also classified by the agency responsible for fire protection. Federal Responsibility Area (FRA) falls to federal agencies such as the US Forest Service, the Bureau of Land Management, and the National Park Service. State Responsibilities Area (SRA), which includes unincorporated land within counties that has statewide watershed value, falls to the Cal Fire. Local Responsibility Area (LRA), which includes portions of incorporated cities with identified wildfire hazard zones, falls to local governments. Only the very high FHSZs located within the LRA are identified and mapped by Cal Fire. However, in the SRA, high and moderate FHSZs are also mapped by Cal Fire.
Due to the San Joaquin Hills’ topography, Aliso Viejo is susceptible to wildfires. The community of Aliso Viejo is located in the San Joaquin Hills and portions of the city are located within the wildland-urban interface (WUI). The WUI is the zone of transition between the wilderness and human-developed lands. Wildfires present a significant threat to the city and the County located in or near the WUI, as it is a region of r elatively high temperatures, low humidity, and low precipitation during the summer. The fall brings with it the Santa Ana winds, which exacerbate the area's already dry conditions, increasing the foothills' susceptibility to wildfire. Fire threat assessment and Geographic Information System (GIS) mapping for Aliso Viejo identifies the WUI as the area with the city that has the highest risk of fire. Figure 3-4 identifies portions of the city located within the WUI as well as historic fire perimeters in the city.
According to Cal Fire FHSZ mapping of the city, the western and southern borders of the city are located within a Very High Fire Hazard Severity Zone (VHFHSZ) falling under the jurisdictional responsibility of the City as it is located in the LRA. The potential for wildfire is even greater considering that these same western and southern border s are also adjacent to the VHFHSZs and HFHSZs of the SRA along the city limits. The potential for a wildfire to begin in the SRA and spreading into the LRA of the cit y has a high probability if the fire cannot be contained with the SRA. Figure 3-5 identifies the fire hazard zones within the city and the surrounding area, including the state responsibility areas (SRA) and the local responsibility areas (LRA). The zones depicted include the SRA, which is primarily unincorporated Orange County, under the jurisdiction of CAL Fire, while the LRA is under the control of the Orange County Fire Authority (OCFA). 106

41 The city’s sphere of influence extends into the SRA and the Very High Fire Hazard Severity Zones (VHFHSZ) associated with this area. Development requirements within this area are regulated and must meet the development requirements for areas located within VHFHSZs.
A fire can only ignite if three elements are present: heat, fuel, and oxygen. If any one of these elements is removed, the fire will extinguish itself. In Aliso Viejo, there are copious amounts of fuel given to the thousands of structures which makes them extremely flammable. Activity that creates intense heat that is unmonitored or unregulated may lead to the ignition of a fire. The National Institute of Standards and Technology, Fire Research Division has developed a scale that measures the increase in temperature and the kind of fire response that develops. Table 3- 9 shows the progression of temperature relative to fire response.
TABLE 3-9: FIRE SUSCEPTIBILITY BASED ON TEMPERATURE INCREASE Temperature (°F) Response
98.6 °F Average normal human oral/body temperature.
101 °F Typical body core temperature for a working fire fighter. 109 °F Human body core temperature that may cause death. 111 °F Human skin temperature when pain is felt.
118 °F Human skin temperature causing a first-degree burn injury. 130 °F Hot water causes a scald burn injury with 30 s exposure. 131 °F Human skin temperature with blistering and second degree burn injury. 140 °F Temperature when burned human tissue becomes numb. 162 °F Human skin temperature at which tissue is instantly destroyed. 212 °F Temperature when water boils and produces steam. 482 °F Temperature when charring of natural cotton begins. >572 °F Modern synthetic protective clothing fabrics begin to char. ≥752 °F Temperature of gases at the beginning of room flashover. ≈1832 °F Temperature inside a room undergoing flashover.
Once a fire has been ignited, it could conceivably grow to an indefinite size if abundant fuel and oxygen are available. For example, a fire that ignites in one house could hypothetically continue to expand and even spread to other adjacent houses if there was enough fuel to link the structures together. Fires in confined spaces may occasionally burn so intensely that they consume all the oxygen available and burn out before they can expand.
Urban Fire
Most of Aliso Viejo’s buildings consist of wooden-frame construction, which is susceptible to catching fire. Even structures that do not have wooden frames, such as large medical facilities or office towers, are at risk of urban fires. These locations contain furniture, papers, plant material, textiles, and other objects that can be ignited. Given that a significant portion of Aliso Viejo is developed, urban fires can occur at any location in the city since any one of these structures has the potential to burn.
Fires are also likely to occur where significant pieces of infrastructure are located, such as gas pipelines, power lines, or highways. SoCalGas operates large high-pressure gas pipelines that run underneath streets and sidewalks of the city. If a pipeline were to breach and the released gas ignites, any structures located along the extent of the breach would likely catch fire. SoCal Edison owns and operates above-ground, high-voltage transmission lines strung from towers on 109
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
42 a right-of-way through the city. While there are no structures directly beneath the towers in the utility right- of-way, several trees and an extensive lawn could ignite if a downed power line encountered them. If this landscaped space caught fire, it could spread to surrounding homes and buildings if hot cinders from the fire came in contact with the buildings. State Route 73 also runs through the city and carries thousands of vehicles every day. If a major transportation accident were to occur on this highway, it could potentially cause a fire. Given that the highway is non-flammable, it is anticipated that a fire that begins on the highway would most likely be contained to the highway. It is possible that an intense fire on this highway could spread to nearby homes, businesses, and landscaping that runs along SR-73.
PAST EVENTS
Wildland Fire
October 27, 1993 – A massive wildfire called the Laguna Beach Firestorm, started as a brush fire in Laguna Canyon, when embers jumped a firebreak into Laguna Beach and Emerald Bay, spreading into the Laguna Coast Wilderness Park just west of what is now Aliso Viejo. The fire burned some 16,000 acres, spread north across S -73, east to the S -133 (Laguna Canyon Rd) and as far south as PCH (S -1). The fire destroyed or severely damaged over 400 homes and caused approximately $528 million dollars in damage.
October 21, 2007 - Orange County’s Santiago Fire burned 28,400 acres and 15 homes were lost and 8 damaged. Fortunately, there were no deaths in Orange County. Orange County Sheriff’s Department personnel serving the City were deployed to help with evacuations and fire watch duty to look for hot spots in coordination with Orange County Fire Authority (OCFA) personnel.
Fortunately, there was no damage in the City of Aliso Viejo.
June 2, 2018 – The Aliso Fire broke out along a trail in the Aliso Woods Canyon near Aliso Viejo’s Soka University of America. The fire burned over 200 acres and was driven unpredictably by winds in the area. The fire prompted evacuations in both Aliso Viejo and Laguna Beach and was responded to by more than 400 firefighters comprising of eight fire strike teams, including six air tankers and four helicopters to combat the fire. Fortunately, no injuries or structural damage were reported.
August 14, 2021 – A brush fire near Pacific Park Drive and Alicia Parkway was quickly contained in the city. Responding fire crews were able to contain the blaze to only 2 acres and no residents or structures were reported as harmed or damaged.
May 11, 2022 – A fire began in the Aliso and Wood Canyons Wilderness Park quickly spreading into the canyon area between Laguna Niguel and Aliso Viejo. The fire burned over 200 acres, destroyed 20 structures, and damaged 12 others, resulting in mandatory evacuations, and over 550 firefighters responded and battled the blaze until it was fully contained on May 17.
Urban Fire
February 18, 2020 - A fire started after a natural gas line was accidentally ruptured by construction crews. Fire crews were able to contain the fire until the gas company was able to arrive and shut off the gas. A neighboring gas station and strip mall were evacuated as a precaution. No injuries were reported.
February 2, 2021 – Fire crew responded to an apartment fire on the 23000 block of Windsong, near Aliso Creek Rd, the crew extinguished the flames in 24 minutes and were able to keep the 110
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
43 fire from spreading to nearby units. Unfortunately, one person was found deceased inside the unit.
September 9, 2021 – Lightning struck the garage of a home on Birchmont in Aliso Viejo, setting it on fire. When fire crews arrived, they found the garage fully engulfed in flames, but the main part of the home was saved due to the fire crew’s quick actions. The vehicle within the garage was fully charred.
RISK OF FUTURE EVENTS
Wildland Fire
The history of wildfires in Orange County , Laguna Canyon, the San Joaquin Foothills, and the area surrounding Aliso Viejo, and continued development within the City’s WUI, which includes the very high fire hazard severity zones (VHFHSZ), indicates that wildfire events are likely to occur in the future. Since 2001, several major wildfire events have affected the city, equating to a return interval of approximately one fire every five years. This risk is expected to remain highest in the undeveloped land in the foothills and canyons within both the city and the county's unincorporated areas, as well as the wilderness parks surrounding the city.
Urban Fire
If the conditions for an urban fire exist in Aliso Viejo, the city will forever be at risk of experiencing an urban fire event. It is impossible to predict the precise likelihood of an urban fire emerging in the city, given how each fire event has unique origins. Some areas, however, are at an increased risk of an urban fire igniting, including the buildings along the SoCalGas pipeline’s course through the City, in addition to the landscaping and properties along State Route 73. Given that no records of urban fire outbreaks in Aliso Viejo could be found, the overall likelihood of an urban fire starting in Aliso Viejo is exceptionally low.
CLIMATE CHANGE CONSIDERATIONS
Wildland Fire
Climate change is expected to cause an increase in temperatures and more frequent and intense drought conditions. This increase will likely increase the amount of dry plant matter available for fuel, increasing wildfire risk statewide. Climate change is ex pected to increase the number of acres burned annually in the San Joaquin Foothills, which are already highly prone to wildfires.
However, increases in fuel supplies could cause wildfires to move faster or spread into more- developed areas, increasing the future threat to Aliso Viejo and other surrounding communities.
Urban Fire
While climate change has been linked to a potential increase in wildfire events, it is not clear exactly how climate change could influence the ignition or behavior of urban fires in Aliso Viejo.
HUMAN-CAUSED HAZARDS (MASS CASUALTY INCIDENT (TERRORISM), CYBER
THREAT)
The Human-Caused Hazards profile discusses mass casualty incidents (terrorism), and cyber threats.
DESCRIPTION
Mass Casualty Incident
Terrorism is the use or threat of force to achieve a particular social or political outcome. The goals of terrorism may sometimes be the overturning of a government, the reversal of a public policy, the release of political prisoners, and other such motives. Acts of terror may overlap with acts of 111
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
44 war or hate crimes. Generally, terrorism involves an attempt to kill or seriously harm people or disrupt civil society by destroying property or infrastructure, attacking government operations at all levels, interrupting essential public services, creating chaos, or a combination of some or all these goals. Firearms and explosives are the most common weapons used among terrorists. In extreme situations, terrorists may gain access to weapons of mass destruction, including bioweapons, chemical agents, radioactive materials, or high-yield explosives. It should be noted that these events are very rare. While incidents of terror caused by foreign individuals or groups receive significant media and public attention, most acts of terror in the United States have been caused by domestic terrorists.
A mass casualty incident describes an incident within the United States in which emergency medical service resources, such as personnel and equipment, are overwhelmed by the number and severity of casualties. The more commonly recognized events of this type include building collapses, active shooter incidents, train and bus collisions, plane crashes, earthquakes, and other large-scale emergencies. The most common types are generally caused by terrorism, mass- transportation accidents, or natural disasters. Events such as the Oklahoma City bombing in 1995 and the September 11 attacks in 2001 are well-publicized examples of mass casualty incidents.
Cyber Threat
Cyber threats are when an individual or a group threatens or attempts to disrupt the operations and functioning of the computer systems belonging to private citizens, religious groups, educational institutions, government agencies, or businesses. These thr eats take the form of online harassment, hacking, or in-person tampering with electronic equipment. Successful cyber threats can lead to service disruptions, infrastructure damage, theft and may cause injury or death in severe instances.
LOCATION AND EXTENT
Mass Casualty Incident
Mass Casualty Incidents can occur anywhere, although public spaces and locations where many people congregate (parks, schools, places of worship, government facilities, shopping centers, and areas of public gathering) are most common. Key locations in Alis o Viejo may be large shopping and entertainment centers (i.e., Aliso Viejo Town Center), governmental facilities (i.e., City Hall), universities (i.e., Soka University of America), schools, medical facilities, and parks (i.e., Grand Park).
Acts of terrorism may occur at the locations listed above; however, the perpetrators may also choose high-value targets such as electric substations, water treatment plants, levees or reservoirs, airports, highways, and other facilities that could impact governmental services.
Mass Casualty Incidents and acts of terrorism are typically measured by the fatalities, injuries, and destruction they cause, but no universal scale is used to measure these events.
Cyber Threat
Since computers are so ubiquitous, a cyber threat could appear in virtually any part of the city. In extreme circumstances, a threat could impact the entire city. Cyber threats vary in their length and severity in impact. A minor threat could cause computer systems to slow down for a few minutes and not behave as responsively. On the other hand, a major cyber threat could cause a complete shutdown of critical systems, including those used by banks, healthcare institutions, universities, major businesses, and city governments.
Cyber threats are not measured on any scale, but they can be assessed by determining:
The type of incident (website defacement, denial of service, unauthorized surveillance) The use of malicious software
The level of security countermeasures that failed in preventing the cyber threat 112
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
45 The duration of the cyber threat (a few hours, a few days, several weeks, etc.)11 Globally, cyber threats are increasing and becoming more sophisticated. The most common types of attacks include:
Phishing
Ransomware
Intellectual Property Theft
Spyware/Malware
Unpatched Software
To understand the status of cyber threats, the Index of Cyber Security (Figure 3-6) can be referenced. The Index of Cyber Security is a measure of perceived risk. A higher index value indicates a perception of increasing risk, while a lower index indicates the opposite. The Index of Cyber Security aggregates the views of information security industry professionals as expressed through a monthly survey.
The Index of Cyber Security will directly:
Assess the level of risk as perceived by practicing security professionals Communicate their combined opinion to the larger community Provide a baseline status against which other individual practitioners can compare their own views
Since 2015 this index has trended upward and appears to have doubled in this timeframe.

46 PAST EVENTS
Mass Casualty Incident
The following mass casualty incidents/ terrorism events have occurred within Aliso Viejo, Orange County, the State, or the Country and may be relevant to the community:
October 1 8, 1970 - Bombing of the Stanford Research Institute facility, which caused approximately $500,000 in property damage. No injuries or deaths occurred during this incident.12 October 26, 1970 - Bombing of a Bank of America Branch, which caused approximately $500,000 in property damage. No injuries or deaths occurred during this incident13 April 19, 1995 - Timothy McVeigh detonated a bomb outside the Alfred P . Murrah Federal Building in Oklahoma City, OK. The blast was so powerful that the Federal Building was destroyed, and more than 300 nearby buildings were damaged or destroyed. The bombing killed 168 people, including 19 children. Timothy McVeigh’s motive for bombing the Federal Building was that he hoped to inspire a revolution against the federal government.14 September 11, 2001 - Terrorists hijacked four commercial airliners. The hijackers flew two of the planes into the twin towers at the World Trade Center in New York City and one into the Pentagon in Arlington, VA. The fourth plane crashed in a field in rural Pennsylvania. The attacks on 9/11 killed 2,976 people and injured thousands more.15
April 15, 2013, - Two bombs detonated near the finish line of the Boston Marathon. The explosion killed 3 spectators and wounded more than 264 other people. Police captured 19-year -old Dzhokhar Tsarnaev in connection with the bombing; the second suspect, Tamerlan Tsarnaev, died following a shootout with law enforcement. Investigators concluded that the Tsarnaev brothers planned and carried out the attack on their own and were not connected to any specific terrorist group.16
December 2, 2015 - A terrorist attack, consisting of a mass shooting and an attempted bombing, occurred at the Inland Regional Center in San Bernardino, California. The perpetrators, Syed Rizwan Farook and Tashfeen Malik, a married couple living in the city of Redlands, targeted a San Bernardino County Department of Public Health training event and Christmas party of about 80 employees in a rented banquet room. Fourteen people were killed, and twenty-two others were seriously injured. Farook was a U.S.-born citizen of Pakistani descent, who worked as a health department employee.17
October 1, 2017 - Stephen Paddock opened fire on the Route 91 Harvest Festival concert in Las Vegas, from an elevated position at the Mandalay Bay Hotel. The attack resulted in 61 people killed (including two victims who died in 2019 and 2020, and Paddock himself) and 867 injured.
Paddock shot and killed himself before responding officers reached him. The FBI Behavioral Analysis Unit determined that there was no clear motivation for the attack. Although this attack did not occur in California, many California residents were affected by the event as more than half the 61 people killed were from California.18
May 15, 2018 – A bomb explodes at the Magyar Kozmetica spa in Aliso Viejo. The resulting explosion killed the owner and seriously injured two clients of the day spa. Witnesses said that the explosion occurred when the owner opened a cardboard box. Stephen Beal, co-owner of the spa and ex -boyfriend, was arrested as a suspect in the explosion. Chemicals used to create explosives were found in his home and were similar to those detected at the explosion site, as

47 well as bits of wire and other materials that were used in the bomb’s construction. Beal was charged for the crime. He was convicted and found guilty of 4 felonies in July of 2023 and faces a minimum of 30 years in prison.19
Cyber Threat
The City of Aliso Viejo has not experienced cyber incidents directly. However, several jurisdictions in southern California and across the country have. Several recent incidents local to the city include:
December 24, 2019 - The City of Seal Beach was the victim of a ransomware attack that affected City computer systems. The attack was targeted at the City’s Information Technology service provider, which allowed the hackers to encrypt City computers with the malware, primarily impacting city email and voicemail functions.
December 4, 2019 - The Cucamonga Valley Water District disclosed a data breach that occurred between August 26, 2019, and October 14, 2019. The breach occurred on a server used to accept one-time credit card payments from customers.
March 11, 2019, the Orange County Sanitation District was the victim of a phishing data breach.
Over 1,000 employee records were accessed as part of the breach through the District deferred compensation plan.
April 23, 2023 – The San Bernardino County Sheriff’s Department was hit with a cyberattack, when a hyperlink loaded with malicious malware was clicked, which resulted in the sudden encryption of many of the department’s systems and subsequent ransom demand to restore functionality. San Bernardino County paid a $1.1 million ransom to the hacker, approximately half of which was covered by insurance as the County had anticipated the possibility of such an attack.
In addition to these, recent, notable cybersecurity events in the US include the Colonial Pipeline incident, JBS (the world’s largest meatpacker), and the Washington DC Metropolitan Police Department. These attacks have resulted in the shutdown or delay in critical services and functions that have increased the cost of goods/services, financial losses, and operational delays.
RISK OF FUTURE EVENTS
Mass Casualty Incident
Given that mass casualty incidents and acts of terrorism stem from a variety of factors: economics, societal pressures, mental health, global geopolitics, warfare, and religion, etc.—it is impossible to predict when an incident occurs. While Aliso Viejo does not feature critical national or state facilities, future incidents would likely originate domestically and are less likely to attract the attention of international terrorist groups. Incidents of these types are more likely to be conducted by smaller o rganizations or individuals aligned with greater -known organizations, although the effects may be no less significant.
Cyber Threat
Due to the integrated nature of technology into the everyday lives of Aliso Viejo ’s residents, businesses, and government operations, it is possible that a cyber threat could emerge in the future. While no cyber threats are publicly known to have disrupted the City’s normal operations in the past, the likelihood of a cyber threat affecting the residents, businesses, and/or governmental operations in the future is increasing.
For all of these hazards the combined future probability is greater than 90% each year, mainly due in part to the threat of cyber intrusion. This occurs on an ongoing basis. However, recent civil disturbance incidents during the COVID pandemic highlight the prevalence of this threat to the city. While terrorist/mass -casualty incidents have not occurred and are considered a low

City of Aliso Viejo 2024 Local Hazard Mitigation Plan
48 probability threat, the city has several locations that could be targets for these types of activities, which increases the concern associated with this type of incident.
CLIMATE CHANGE CONSIDERATIONS
Mass Casualty Incident
The link between mass casualty incidents/terrorism and climate change is not well understood.
However, it has been suggested that the impacts of a changing climate may exacerbate existing social, political, religious, and ethnic tensions. For example, longer, more intense droughts may restrict food supply or limit economic growth for cities, regions, or even whole countries.
Nevertheless, the likelihood of climate change impacting mass casualty incidents/acts of terrorism in Aliso Viejo is negligible since these changes are more likely to impact developments on the national or international level.
Cyber Threat
Climate change is not likely to impact cyber threats in the future within Aliso Viejo.
SEVERE WEATHER (WINDSTORM, WINTER/COASTAL STORMS)
DESCRIPTION
Windstorms
Windstorms and severe weather pose a risk to life and property in the region by creating conditions that disrupt essential systems such as public utilities, telecommunications, and transportation routes. High winds can and do occasionally cause tornado-like damage to local homes and businesses. Severe windstorms can present a very destabilizing effect on the dry brush that covers local hillsides and urban wildland interface areas. High winds can have destructive impacts, especially to trees, power lines, and other utility services. In Aliso Viejo, severe weather patterns, such as Santa Ana Wind conditions are a recognized hazard.
Wind is simply the movement of air caused by differences in atmospheric temperature. High- pressure air will naturally move to areas of low pressure. Usually, the distance between these high- and low-pressure zones is far; however, on occasion, these low - and high-pressure zones may be near one another. When this happens, air will flow dramatically, creating high-speed winds. The most common wind events in southern California are the “Santa Ana” wind conditions that typically occur in the fall and winter.
When winds are fast enough, they can
cause property damage to homes, public
facilities, utilities, and other
infrastructure. They can also uproot or
topple mature trees or pick up debris and
send it careening through the air. This
debris can injure or even kill bystanders
who may find themselves stranded
outside. High-speed winds can also
deposit this debris in the middle of rights-
of-way, such as roads, freeways, and
railways, blocking exit routes for would-
be evacuees or impeding access to first
responders trying to reach wounded
people.

49 Winter/Coastal Storms
Winter/Coastal storms are also known as thunderstorms. A thunderstorm is a storm with lightning and thunder, produced by a cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail. A typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes.
A thunderstorm is formed from a combination of moisture, rapidly rising warm air and a force capable of lifting air such as a warm and cold front, a sea breeze or a mountain. During severe weather events such as thunderstorms, rain can fall at such a high rate that it cannot drain away fast enough. The resulting heavy rain can cause flooding, leading to inundation and potential damage to buildings, road networks, public areas, utilities, and other critical pieces of infrastructure. In California, heavy rainfall events are often short, intense bursts of rain, but in some cases, heavy rain can persist for multiple days
All thunderstorms are dangerous. About 10% of the thunderstorms that occur each year in the United States are classified as severe. (A thunderstorm is considered severe if it produces hail at least 3/4 inch in diameter, winds 58mph or greater, or tornadoes.) Heavy rain from thunderstorms can lead to flash flooding (which is the number one thunderstorm killer.) Strong winds, hail, and tornadoes are also dangers associated with some thunderstorms.
LOCATION AND EXTENT
Windstorm
In Southern California, the most common type of severe wind event is called the Santa Ana winds.
During the fall and winter months, high pressure over Nevada and Utah forces air currents down from the high desert toward the ocean. As the winds descend, they heat up and increase in speed, sometimes carrying particulate matter and aggravating the respiratory health of those who have allergies.
20 The e ntirety of the City can be affected by windstorms, usually they cause minimal damage, however severe storms can cause massive damage to the City and personal property. Aliso Viejo is often affected by Santa Ana winds blowing through the San Joaquin Hills. Santa Ana winds are a leading cause of wildfires in California.
Generally, winds are measured using the Beaufort scale, developed in 1805, categorizing wind events on a force scale from 0 to 12 using their speed and impacts. Any wind that is classified as force nine or above is generally considered a severe wind event. Table 3-10 shows how the Beaufort scale classifies wind events in detail.

50 Winter/Coastal Storms
The location and size of a rain event vary depending on regional geography and regional and global weather events. For example, small precipitation events may occur in only one section of Aliso Viejo. In contrast, a large rain event could inundate a majority of Orange County and other parts of southern California. Understanding this, any part of the city could become inundated by rain, not one part of the city is more susceptible to rainfall than another.
California’s precipitation varies from year to year, depending on how much moisture the state receives from atmospheric rivers. Atmospheric rivers are corridors along which wet air travels from the tropics to continents. When the moisture arrives in California, it may precipitate as rain or snow. One of California's most known atmospheric rivers is the “Pineapple Express,” which brings moist air from the ocean surrounding Hawaii to California. An immense amount of moisture may be transported along the atmospheric rivers that cross over California during certain years, leading to severe rain.
21 Another weather phenomenon influencing rainfall in southern California is “El Niño,” officially referred to as the “Southern Oscillation” or “El Niño-Southern Oscillation (ENSO).” ENSO can cause increased rainfall, particularly during the winter months, caused by warming of the surface of the eastern tropical Pacific Ocean, leading to the evaporation of warm, moist air into the atmosphere. Winds bring this moisture to the eastern Pacific and the American continents, where it falls as rain. ENSO does not always lead to increased rainfall by default, but in general, it can increase the chances of winter with higher-than-usual precipitation. 22,23

54 RISK OF FUTURE EVENTS
Windstorm
Given the region’s history of severe wind events in nearby cities, it is very likely that wind events will continue to impact the city. The most probable source of wind events in the future will likely originate from the Santa Ana winds or extreme storms. All expectations are that the probability of windstorm events occurring again in the future is highly likely. As discussed in Table 3-2 , a probability of “highly likely” indicates that there is a greater than ten percent chance of windstorms occurring annually.
Winter/Coastal Storms
There is no indication that rainfall or severe rain hazards will abate either in Aliso Viejo or the greater region of Southern California in the future. While Aliso Viejo may experience prolonged periods of dry or wet years, all expectations are that the probability they will occur again in the future is highly likely and anticipated to increase in the future is highly likely. As identified in Tables 3-2 and 3-3, the future probability for this hazard is more than 90 percent chance each year.
CLIMATE CHANGE CONSIDERATIONS
Windstorm
It is anticipated that the atmospheric rivers that deliver storms to Southern California may intensify because of climate change. While the average number of storms in Southern California will remain the same, storms are expected to increase in intensity between 10 and 20 percent. 26 This increase
in storm intensity may also bring more intense winds to the Southern California region, including Aliso Viejo.
Studies indicate that Santa Ana wind events may be affected in varying ways by climate change, but it is unknown whether the frequency and intensity of events may be some of those ways.
According to one study that examined two global climate models, there is a projected increase in future Santa Ana events. However, other studies have found that the number of Santa Ana events may decrease by about 20% in the future.
27 Given the anticipated increases in temperatures
throughout the region, future events are anticipated to become more severe in some cases, even if the number of events decreases.
Winter/Coastal Storms
Climate change is expected to alter rainfall patterns in southern California, including Aliso Viejo.
As the climate warms, rain events are predicted to become more intense. Aliso Viejo will likely experience more rain inundation events that lead to flooding and erosion and increase the threat of dam failure, landslides, and other potential hazards within the community and surrounding area.
LANDSLIDE
DESCRIPTION
Landslides are a serious geologic hazard in almost every state in America. Nationally, landslides cause 25 to 50 deaths each year. The best estimate of direct and indirect costs of landslide damage in the United States range between $1 and $2 billion annually. As a seismically active region, California has had a significant number of locations impacted by landslides. Some landslides result in private property damage, other landslides impact transportation corridors, fuel and energy conduits, and communication facilities. They can also pose a serious threat to human

55 life.
Landslides occur when slopes become destabilized, typically after heavy rains. If precipitation saturates soils, they can become unstable, or landslides can occur when significant erosion from rainfall destabilizes the ground. Slopes that have recently bur ned face a greater risk from rain- induced landslides, as the loss of vegetation can de-stabilize the earth. Earthquakes may also be a source of landslides as the shaking can destabilize steep hillsides covered in loose soils and weak rock layers.
Landslides can be broken down into two categories: (1) rapidly moving (generally known as debris flows), and (2) slow moving. Rapidly moving landslides or debris flows present the greatest risk to human life, and people living in or traveling through areas prone to rapidly moving landslides are at increased risk of serious injury. Slow moving landslides can cause significant property damage but are less likely to result in serious human injuries.
LOCATION AND EXTENT
Identifying hazardous locations is an essential step toward implementing more informed mitigation activities. The City’s foothill areas along with the structures and people located in these areas are vulnerable to slope instability. According to the California Division of Mines and Geology, slope instability is a concern in the San Juan Capistrano Quadrangle and the Laguna Beach Quadrangle, which together encompass most of the City of Aliso Viejo. Slope stability hazards in the city correspond primarily to the City's undeveloped areas, as grading activities and soil remediation techniques have been used to help mitigate these hazards prior to development.
In the City of Aliso Viejo, land sliding and debris flows are the dominant geologic hazard risks.
This is based on abundant shales and siltstones that underlie the City’s hills that are highly porous and do not hold together well when wet. This can lead to slope instability and landslides. In addition, factors that contribute to slope instability and landslides include rainfall and earthquakes.
Debris flows can occur rapidly and without warning during periods of exceptionally high rainfall.
Although rockfall hazards are low in the city, mudflows are more likely to occur.
The potential for slope failure is dependent on many factors and their interrelationships. Some of the most important factors include slope height, slope steepness, sheer strength, and orientation of weak layers in the underlying geologic unity, as well as poor water pressures. Joints and shears, which weaken the rock fabric, allow penetration of water leading to deeper weathering of the rock along with increasing the pressures, increasing the plasticity of weak clays, and increasing the weight of the landmass. For engineering of earth materials, these factors are combined in calculations to determine if a slope meets a minimum safety standard. The generally accepted standard is a factor of safety of 1.5 or greater, where (1.0 equilibrium and less than 1.0 is failure). Although existing landslides are not widespread in the area, it is probable that many of the steeper hillsides do not meet the minimum factor of safety and slope stabilization may be needed if development reaches these areas. Natural slopes, graded slopes, or graded/natural slope combinations must meet these minimum engineering standards where they impact planned homes, subdivisions, or other types of developments. Slopes adjacent to areas where the risk of economic losses from land sliding is small, such as parks and mountain roadways, are often allowed a lesser factor of safety. Figure 3-7 shows the areas of the city mapped as landslide hazard zones.
While no definitive scale for measuring landslides exists, landslide events are usually measured using the amount of material that is displaced (i.e., the cubic feet of earth that moved). In addition, to these landslide hazards, the California Geological S urvey has mapped deep-seated landslide hazards, which uses a scale of landslide susceptibility that is based on slope steepness and the strength of the underlying rock, with 0 being no susceptibility and 10 being the highest 123
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
56 susceptibility. Figure 3-8 identifies these categories and where they are located within the city .
To make the map more accessible and eas ier to read, the risk values (0-10) were aggregated and placed into one of three categories, High Susceptibility (10-8), Medium Susceptibility (7-5), and Low Susceptibility (4-0).

59 PAST EVENTS
Aliso Viejo is located in the San Joaquin f oothills. The hilly topography of the city and the surrounding area make it susceptible to landslides. Given this topography there have been some major landslides within the county and in the region. Table 3-14 lists some of these major landslide events.
TABLE 3-14: MAJOR LANDSLIDE EVENTS IN AND AROUND ALISO VIEJO Date Event
10/02/1978
Bluebird Canyon, Laguna Beach - Unusually heavy rains in March of 1978 may have contributed to initiation of the landslide. Although the 1978 slide area was approximately
3.5 acres, it is suspected to be a portion of a larger, ancient landslide. 60 houses destroyed or damaged, causing at the time, over $52 million dollars in damages. 01/19/1993
Anaheim Hills - Following a major El Niño weather event, a bluff in east Anaheim Hills slid and prompted the evacuation of dozens of families, destroyed over 30 homes, and impacted over 200 other structures in the vicinity.28
12/06/1997
Orange County - Four homes were condemned and evacuated due to a mudslide and rockfall in Silverado Canyon. Floods and mudslides were reported in Costa Mesa, Irvine, Lake Forest, San Juan Capistrano, and Laguna Beach. Mudslides occurred in Black Star, Baker, and Santiago Canyons. Many road closures were reported along the Santa Ana Freeway at Laguna Freeway, Laguna Canyon Road, and Pacific Coast Highway in Newport Beach and in Huntington Beach.
12/23/1997
Anaheim Hills - Movement of an active landslide in Anaheim Hills accelerated. The landslide, which is located within a mapped landslide, had been active for the past two years. This "Vista Summit Way" landslide damaged two to three houses and affected three city blocks.
03/19/1998
Laguna Niguel - During the 1997/1998 El Nino Season heavy rainfall increased movement on the site of an ancient landslide in Laguna Niguel. The storms in December 1997 had accelerated its movement and in early 1998, a crumbling hillside forced the evacuation of 10 hill top homes and more than 10 condominium units resting below.
Ultimately four of the hilltop homes collapsed, falling down hillside into the void created by the slide area. The condominium complex has since been demolished and the site sits as open space.
Early 2005 Anaheim Hills - Three new multi -million-dollar homes along Ramsgate Drive were destroyed by this slow-moving landslide in 2004-05.
01/06/2005
Mission Viejo - The City experienced a large residential landslide between Ferrocarril and Encorvado Lane during the 2005 winter storms. This landslide consisted of an approximately 300 foot wide by 70-foot-high slope failure that occurred due to extreme rains that fell during the winter months. The failure occurred along a deep- seated slide plan along a clay bed that was lubricated by water saturation. 02/25/2005
Aliso Viejo – Two homes were left with a 17 by 70 feet wide gap a few feet from their homes along the Hollyleaf slope in the master planned community, when the slope suddenly collapsed. The Aliso Viejo Community Association (AVCA) was responsible for the maintenance and repair of the slope and was sued by two homeowners. The lawsuit was settled and dismissed in 2007.
2007-2008
(Post-Santiago
Fire)
2014-2015
(Post-
Silverado Fire)
Debris Flows
Orange County Canyon Communities - Following the 2007 Santiago Fire that stripped the vegetation bare in the canyon communities of Orange County, a debris flow task force was convened to address the potential impact that post-fire winter storms could have on the slopes in the burn areas. There have been several cases of mudslides that have damaged homes. It is expected that preparedness and mitigation measures will have to be instituted for up to five years after the fire.
Following the Silverado Fire in 2014, similar conditions were generated in the Silverado Canyon area of Orange County. While no major debris flows have been recorded in the year following the event, the threat will remain for several more years.

City of Aliso Viejo 2024 Local Hazard Mitigation Plan
60 RISK OF FUTURE EVENTS
The potential for landslides will continue to exist in areas of the city, especially those areas in Aliso Viejo located along the canyons and hillier sections of the city. All expectations are that the probability of a landslide occurring again in the future is likely. As discussed in Table 3-2 , a probability of “ likely” indicates there is between a one and ten percent chance of a landslide occurring annually.
CLIMATE CHANGE CONSIDERATIONS
Due to the wide variety of factors that can lead to landslides, it is possible that climate change could indirectly affect the conditions for landslides. Increased frequency and more intense storms may cause more moisture-induced landslides. Warmer temperatures and more frequent drought conditions may lead to more fires, destabilizing soil on slopes, and making future landslide events more likely.
HAZARDOUS MATERIALS RELEASE
DESCRIPTION
The state of California defines hazardous materials as substances that are toxic, ignitable, or flammable, reactive, and/or corrosive. The state also defines hazardous materials as substances that show high acute or chronic toxicity, are carcinogenic (causes cancer), have bio accumulative properties (accumulates in the body’s tissues), are persistent in the environment, or are water reactive. The primary concern associated with a hazardous materials release is the public's short and/or long-term effects from exposure to the hazardous material.
Hazardous materials release refers to a hazard event whereby harmful concentrations of hazardous or toxic substances are released into the environment. This occurs when storage containers of hazardous materials leak or fail. This can happen due to industrial accidents, vehicle crashes, as a direct result of other disasters (e.g., a flood or earthquake), or as a deliberate act.
The threat that hazardous materials pose to human health depends on the type of material, frequency, and duration of exposure, and whether chemicals are inhaled, penetrate the skin, or are ingested, among other factors. Exposure to hazardous materials can result in short- or long- term effects, including major damage to organs and systems in the body or death. Hazardous waste is any material with properties that make it dangerous or potentially harmful to human health or the environment and is no longer of use requiring disposal. Hazardous materials can also cause health risks if they contaminate soil, groundwater, and air, potentially posing a threat long after the initial release.
LOCATION AND EXTENT
Hazardous materials and chemicals are used daily in households and businesses throughout Aliso Viejo . In addition to the locations of large commercial and industrial uses, sources of hazardous materials can originate from seemingly harmless places such as gas stations, auto repair shops, dry cleaners, medical centers, and almost any industrial business. Hazardous waste can take the form of liquids, solids, contained gases, or sludge and can be the by -products of manufacturing processes or simply discarded commercial products, like cleaning fluids and pesticides.
In severe situations, Aliso Viejo may also be at risk of hazardous materials release events on a regional level. With the right prevailing wind conditions, airborne toxic material could spread to and impact various parts of the air basin, including areas of Aliso Viejo. 128
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
61 Figure 3-9 identifies stationary hazardous materials locations within Aliso Viejo that store, use, or produce hazardous materials regulated by the state. While these locations are fixed, roadways throughout the community are commonly used to transport hazardous materials and waste. These facilities are common locations for spills and releases. While there is no extent scale for hazardous materials release, the probability of an incident is anticipated to be occasional (less than 10% chance of occurrence) each year. Currently, the City has 231 facilities that are registered with the Environmental Protection Agency (EPA). According to the California State Water Resources Control Board, there are a total of 13 sites in the city that required cleanup activity, all 13 cases have been completed and all cases are closed.
PAST EVENTS
Aliso Viejo has experienced an average of 1.43
hazardous materials spills reported annually to the
Cal OES Spill Release Reporting database, Table
3-15 displays this data. Most of these incidents
involve the release of sewage and petroleum
products.
RISK OF FUTURE EVENTS
Most of the release events within Aliso Viejo have
occurred due to human error, malfunctioning
equipment, or as a deliberate act. Given this, it is
anticipated that future events within Aliso Viejo will
include minor incidents like the past occurrences
identified above. Activities to prevent future
releases, as well as response strategies, should
take this into consideration.
CLIMATE CHANGE CONSIDERATIONS
Climate-related natural hazard events, such as
increased precipitation and subsequent flooding,
could cause an increase in hazardous materials
release. Some of these incidents could result from
transportation crashes (due to poorer road
conditions) or damage to storage containers or
vessels containing these substances. Climate-related hazards could also exacerbate the effects and impacts of such events. For example, heavier rains could lead to more runoff from a contaminated site with hazardous materials. These issues should be monitored during the five- year implementation period of this plan.

63 FLOOD
DESCRIPTION
Flooding occurs when an area becomes inundated with more water than it can drain in a specified period. This can range from a small, confined area, such as a grassy field in a park that floods for a few hours after a rainstorm, to whole city sections, such as streets becoming impassable because of floodwaters. When floods are small, they may only represent a minor inconvenience as some recreational pathways and curb cuts become flooded. These smaller instances of flooding where water collects into a pool of standing water are referred to as “ponding.” On the other hand, larger flood events can hamper a city’s operations. For example, if multiple streets flooded simultaneously, the res ults could prevent emergency workers from reaching victims in need of assistance. Flooding also has the destructive potential to damage critical infrastructure. For instance, unprotected electronic equipment can short-circuit if it becomes inundated by floodwaters. This could lead to outages in street lighting, traffic signals, and even city and government computer systems.
Flooding has the potential to occur from multiple sources. In Southern California, the primary cause of flooding is usually heavy rain occurring during the winter storm season. Most precipitation in California arrives either via atmospheric rivers or the E NSO cycle. Atmospheric rivers are channels of moist air located high in the atmosphere. The ENSO cycle is a regional meteorological phenomenon in the southern Pacific Ocean consisting of ocean water and air temperature variations. These variations give ris e to two distinct phases known as El Niño, the warm and wet phase, or La Niña, the dry and cold phase. When the El Niño phase is active, California will likely receive higher than normal precipitation levels. These higher-than- normal levels of rainfall can quickly overwhelm the capacity of certain sections of land to drain the precipitation before the rainwater begins to pool effectively.
A failure in infrastructure may also cause flooding. For example, a water main or sewage pipeline that bursts could cause flooding if left uncontained for a significant period of time. A more serious infrastructure failure, such as the failure of dams, res ervoirs, or levees, could cause extensive flooding.
LOCATION AND EXTENT
The Federal Emergency Management Agency (FEMA) designates which areas in the United States are susceptible to flooding and how likely they are to experience flooding. FEMA uses a complex classification system to categorize the level of risk for each section of land. The two most well-known measures of flood event likelihood are known as the 100-year flood and 500- year flood zones. These designations do not refer to floods that occur every 100 or 500 years but instead to the likelihood of occurring each year. For example, a 100-year flood zone has a 1 in 100—or 1% chance—of occurring in any given year, while a 500-year zone has a 1 in 500—or
0.2% chance—of occurring in any given year. These likelihood measures are combined with each locale's specific geography to produce specific flood “zone” designations. Table 3-16 shows a detailed list of all the flood zone categories used by FEMA.
FEMA also uses Base Flood Elevation (BFE) to determine the minimum depth of the floodwaters during one of these flood events. An area with a BFE of three feet, for example, means that area can expect to see a minimum floodwater depth of three feet with potentially additional depth in particularly severe flood events.
FEMA has designated the vast majority of Aliso Viejo as lying within Zone “X,” generally meaning the city is not in danger of a 500-year flood. The majority of 100-year flood zones in the city are located along the base of the canyons and hills. The city i s at risk of flooding due to surface drainage through the streets and storm drains. The drainage pattern in the City varies, with most runoff conveyed on street surfaces and local storm drain facilities maintained by the 131
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
64 Environmental Services Division of the Public Works department through its stormwater management plan, to the regional facilities owned and maintained by the Orange County Flood Control District. 29 Ponding events occur on any flat surfaces where sufficient drainage is unavailable. These include parking lots, landscaped areas or lawns, or roadways. Since ponding is so small in scale, it is impossible to predict exactly where in the city they will occur or how severe they will be. Figure 3-10 depicts the 100-year and 500-year flood zones in the city as mapped by FEMA. These areas include the Aliso Creek channel located in the eastern portion of the city, adjacent to multiple parks and facilities including Aliso Viejo Community Park, Woodfield Park, Foxborough Park, Hillview Park, and Aliso Niguel High School. There other identified flood zone is located on the western border of the city along the Wood Canyon channel adjacent to El Toro Rd. Both FEMA flood zones cross underneath the SR-73, which in extreme situations could disrupt the City’s transportation network and evacuation capacity.

PAST EVENTS
Orange County is no stranger to flooding during massive storm systems and has experienced the destructive effects that occur as a result. Some flooding events have caused damage in the past in the City of Aliso Viejo.
Table 3-18 lists examples of significant historic flooding in the region, as well as some of the local flooding events in the city.30
RISK OF FUTURE EVENTS
Localized instances of ponding occur at least annually or even multiple times a year in cities across Southern California. During periods of drought, precipitation levels may decrease and lower the likelihood of ponding. In most years, though, it is almost certain that Aliso Viejo will experience some type of flood event. Larger -scale flood events have been rare in Aliso Viejo.
However, during a particularly severe rainstorm or after a dam failure, Aliso Viejo could experience some degree of large-scale flooding with inundation levels greater than one foot in depth. All expectations are that the probability of flood/storms occurring again in the future is likely. As discussed in Table 3-2, a probability of “likely” indicates that there is between a one and ten percent chance of floods/storms occurring annually.
CLIMATE CHANGE CONSIDERATIONS
Climate change is expected to exacerbate the conditions that lead to urban flooding in Aliso Viejo.
Climate change will cause more intense local, regional, and global weather patterns, intensifying atmospheric rivers. At this time, it is unknown exactly how climate change will impact ENSO frequency, but it is anticipated that its effects will become more intense. Winter storm precipitation amounts in Southern California will increase based on atmospheric rivers and ENSO changes.
This increases the likelihood of an exceptional rain event in Aliso Viejo that could overwhelm the capacity of the region’s flood control system to contain and drain all the precipitation.
Droughts are also expected to increase in length and frequency due to climate change. Soils dried by extensive drought periods are less able to absorb and drain water, likely increasing flood

67 possibility. Overall, climate change is expected to create conditions that will raise the likelihood of flooding in Aliso Viejo.
TABLE 3-18 HISTORICAL FLOODING IN ALISO VIEJO AND SURROUNDING REGION Date Event
December
1861 to
January
1862
There were 30 consecutive days of rain across Southern California from Los Angeles to San Diego. Thirty-five inches of rain fell in Los Angeles, causing mass flooding around the region’s rivers. Some rivers even changed course, and the mouth of the Los Angeles River shifted from Venice to Long Beach. In Orange County, the Santa Ana Riverbanks in Anaheim created a four-foot-deep layer of water that extended to the Coyote Hills in Fullerton. Twenty people were reported dead in Orange County.
February
to March
of 1938
A weakened tropical storm reached Southern California and dropped 11 inches of rain in Los Angeles and 30 inches in some mountain areas. Flood control infrastructure was overwhelmed with the surge of water, and the Los Angeles, San Gabriel, and Santa Ana Rivers flooded their banks. Two hundred and ten people were reported as dead or missing, including 45 people in Orange County.
April 1988
Heavy rains led to flooding across Southern California, including Orange County. In Los Angeles, 26 motorists were injured in a major collision. Uprooted and felled trees brought down power lines that caused outages in the region.
December
2010
Aliso Viejo, CA, received a record 14.90 inches of rain over a 6-day span, beginning Friday, December 17th through Wednesday, December 22nd. Woods Canyon Creek overflowed its banks. White foam was observed along its banks and believed to be the result of chemicals spilling into the creek from a water treatment plant, located upstream.
June 2014 A water main broke and flooded Alicia Parkway between Pacific Drive and Morning Ridge, causing the street to be closed to traffic until it was capped.

68 CHAPTER 4 – THREAT AND VULNERABILITY
THREAT ASSESSMENT PROCESS
The threat assessment process evaluates the harm Aliso Viejo may experience from a hazard event. Threat assessment does not consider a hazard’s likelihood, so it gives equal consideration to hazards that are more likely (e.g., earthquakes, drought) as well as hazards that are less probable (e.g., urban fire, dam failure). The threat assessment examines three aspects of each hazard: the physical threat to Critical Facilities (CFs) and Facilities of Concern (FOCs), the social threat to vulnerable populations, and the threat to any other assets.
CRITICAL FACILITIES AND FACILITIES OF CONCERN
Critical facilities consist of properties and structures that play important roles in government operations and their services to the community. Examples of CFs include local government offices and yards, community centers, public safety buildings like pol ice and fire stations, schools, and any other properties a city has deemed essential for its operations. C ritical Facilities may also serve dual roles if a city designates them as public assembly points during an emergency. The City often owns CFs, but many are also owned and operated privately, such as some utilities and telecommunication infrastructure. Facilities of concern are structures that play an important role in the city but are not critical to its function. These can be city-owned or privately owned facilities such as senior assisted living homes, parks, and storage facilities, to name a few.
The HMPC identified 8 CFs and 9 FOCs in Aliso Viejo that fall into three different categories based on their function or characteristics. Table 4-1 shows the number of CFs and FOC s in each category, the total estimated value of the facilities in each category, and examples of the facilities in each. Appendix D has a complete list of the CFs and FOCs.
The potential loss value is the total insured value of the CFs that fall within the hazard zone. It is intended to provide an estimate of a replacement cost if the property is completely or severely damaged. The actual repair costs could be smaller or larger than the provided estimate. The data relies on the City’s Insured Asset Values, and therefore, information for facilities not owned by the City is not shown (e.g., bridges, private buildings). In some instances, replacement cost information was not made available. Where this occurs, “N/A” has been used within the table.
Based on the available data provided by the City, there is a minimum of $52,950,504 worth of City-owned assets. The greatest potential for loss among the city -owned assets comes from the City Facilities (City Hall, Fire, Police) category. The next category with the greatest loss potential is the Community Centers category followed by the other facilities of concern category (these values were not available as they are not owned by the City). To better understand the magnitude of impacts, this plan identifies representative percentages of potential impact based on the total valuation of City assets. For planning purposes, it is reasonable to assume that impacts would not exceed 50% of the total asset value city wide. The following are parameters to help understand how much a proposed investment/improvement compares to the existing assets within the city:
1% Impact - $529,505
5% Impact - $2,647,525
10% Impact - $5,295,050
20% Impact - $10,590,101
50% Impact - $26,475,252
The likelihood that all facilities are completely damaged simultaneously is extremely remote. Most impacts are anticipated to be isolated to specific locations based on the hazard. This estimate does not include the value of underground infrastructure and surface drainage facilities owned and operated by the City.

VULNERABLE POPULATIONS
Factors such as age, physical and/or mental condition, socioeconomic status, access to key services, and many other factors affect the ability of people to prepare for and protect themselves and their property from a hazard event. Even though some hazard events may equally impact all parts of Aliso Viejo, people may experience the impacts differently. Higher -income households, for instance, are more likely to afford the cost of retrofitting their homes to resist flooding or move to a location that is less prone to flooding than a lower -income household. As a result, a higher- income household is less likely to experience significant damage during a flood event than a lower-income household, even if the same amount of rain falls on both.
A social threat analysis examines the ways hazard events are likely to impact different demographic populations in Aliso Viejo and where these different demographic populations live in the city. This includes assessing whether the people in an area of an elevated hazard risk are more likely than the average person to be considered a threatened population. The social threat analysis uses the following criteria to assess the threat to vulnerable populations:
• Disability status : Persons with disabilities may have reduced mobility and experience difficulties living independently. As a result, they may have little or no ability to prepare for and mitigate hazard conditions without assistance from others. • Income levels: Lower-income households are less likely to have the financial resources to implement mitigation activities on their residences. Another challenge may be finding adequate time to research and access educational resources about hazard mitigation strategies. Furthermore, lower -income households are less likely to have the necessary resources to move to safer areas that are less at risk of being impacted by a hazard. The national poverty limit standard for the U.S. for a four-person family is approximately an income of $35,750 or less. For Orange County, the FY 2022 Low-Income Limit for a four- person family, according to Housing and Urban Development (HUD), is $108,400. • Seniors (individuals at least 65 years of age): Seniors are more likely to have reduced mobility, physical and/or mental disabilities, and lower -income levels, all of which may decrease their ability to prepare for and mitigate a hazard event.
Table 4-2 shows the metrics for Aliso Viejo residents who meet at least one of the criteria for threatened, vulnerable populations. The social threat analysis also shows the threat other populations may encounter. For example, people experiencing homelessness or people without access to lifelines (vehicles or communication networks) may experience greater hardship in evacuating or recovering from a disaster. Since data for these groups are not readily available, there is no definitive way to determine the number of persons in areas of elevated risk, so this assessment will discuss how these other threatened groups may also be affected on a general level.

DATA LIMITATIONS AND NOTES ON VULNERABILITY TABLES
Due to data limitations, the data comparing the hazard zone population with the citywide population comes from two separate sources. The citywide data comes from the US Census Bureau’s American Community Survey (ACS), and the hazard zone population data comes from ESRI’s Business Analyst reports. As a result, there may be minor discrepancies in comparing the two data sets. The data relies on readily available 2022 US Census Survey Projections and 2017- 2021 U.S. American Community Survey. Chapter 2 identifies additional census -related information, which may be different from the data in this Chapter based on the data available for the analysis.
OTHER ASSETS
In addition to the City’s designated inventory of CFs/FOC s and vulnerable populations, hazard events could threaten other important assets to Aliso Viejo. These assets may include services, artistic or cultural landmarks, or local economic activities. The threat assessment describes the potential harm to these other assets based on available information.

71 EARTHQUAKE HAZARDS (SEISMIC SHAKING, LIQUEFACTION)
PHYSICAL THREAT
Seismic Shaking
Many physical assets in the city are estimated to experience the same seismic shaking intensity, ranging from 0.55 to 0.65g (shaking intensity in relation to earth’s gravity). Therefore, all facilities could potentially be damaged during a significant seismic event, which could be extremely costly for the City. If all facilities were damaged at the same time during a seismic shaking event, it can be assumed that the City would incur a percentage of the maximum potential loss of its physical assets. Assuming 20% of the City’s assets are impacted, this potential loss could amount to over $10.5 million. Underground physical assets, like pipelines or utilities, could be damaged if the intensity of the seismic shaking is severe enough. In such a scenario, natural gas and water delivery service to Aliso Viejo homes and businesses would not be available until repairs are completed. Table 4-3 displays the potential scenario and losses that could incur should shaking reach the described threshold. Figure 4-1 displays the CFs and FOCs located within the City’s Seismic shaking potential hazard zones.
Liquefaction
Due to the City’s location near so many regionally active faults capable of generating large earthquakes, the potential for CFs and FOCs to be affected by liquefaction is a concern. Like other cities in Orange County, Aliso Viejo is located in a geographical area where the soil makeup is conducive to liquefaction hazards in some areas. Table 4-4 identifies the CFs and FOC located within these areas, accounting for over $12.5 million in potential losses affecting 1 CF and 2 FOCs. Figure 4-2 displays the CFs and the FOCs that are located in liquefaction susceptible hazard zones within the city.

74 SOCIAL THREAT
The risk of a seismic event is a danger to all Aliso Viejo households and businesses; however, some populations are at higher risk than others.
Seismic Shaking
Seniors, pregnant women, and persons with disabilities may be at higher risk in a seismic shaking event as they may have limited mobility, which could delay or prevent safe evacuation. Renters and persons with lower incomes are also more threatened by seismic shaking since they may live in homes that are not properly retrofitted to withstand the stresses of a seismic event. These groups may not have the financial resources to repair their homes or move to new housing if their existing home becomes uninhabitable.
Data compares the populations within the seismic shaking hazard zones to the citywide population. Of the approximately 52,005 residents of Aliso Viejo, approximately 56.8% or 29,538 residents live within the 0.55 to 0.65g seismic shake zone. This equates to approximately 11,252, approximately 57.9%, of the City’s 19,431 households being located in a potential seismic shaking hazard zone.
Liquefaction
Just over 2.6 % of the City’s population is located within a designated zone of liquefaction, and over time, mitigation measures have been incorporated into most construction. Newer buildings constructed are anticipated to contain moderate and high-income tenants with greater amounts of disposable income, allowing them to recover after an incident. However, lower -income residents and residents located in areas of older construction may be more impacted, as they may not have the financial resources needed to make repairs and/or retrofit older buildings. Table 4-5 compares threatened populations living within the liquefaction hazard zones to the citywide population. As Aliso Viejo is a newer community, the housing stock is generally newer and the likely hood of retrofit and or repair is low.

OTHER THREATS
Seismic Shaking
Earthquake Warning California is the country’s first publicly available, statewide warning system that could give California residents crucial seconds to take cover before you feel shaking.
Managed by the Governor’s Office of Emergency Services (Cal OES), Earthquake Warning California uses ground motion sensors from across the state to detect earthquakes before humans can feel them and can notify Californians to “Drop, Cover and Hold On” in advance of an 142
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
75 earthquake. The goal of early earthquake warnings systems is to afford utility providers additional time that they may use to shut off gas, water, and power transmission to try and control potential leaks following the event. Authorities may also have enough warning to halt the use of bridges or safely shelter or evacuate workers away from hazardous locations. Therefore, the goal is to allow service providers to remain inactive reducing further impact, until authorities determine it is safe for employees to return and reactivate utilities. The length of this time will vary depending on the event's magnitude. A significant earthquake would necessitate utilities to remain off for a few hours or several days. The city and the region could lose the economic acti vity that normally occurs. In addition, structures such as downed telephone poles or power transmission towers could block roadways and prevent first responders from reaching victims or evacuees who need assistance.
Liquefaction
Services and mobility may be disrupted during and following a liquefaction event. Sidewalks, roadways, and pipelines may become fractured and disjointed because of the liquefying soils.
Severe liquefaction events may render roads and sidewalks impassable until they are repaired.
Broken gas and water pipelines could result in utility outages, with services delayed until the infrastructure is repaired or replaced. Damage to power lines is unlikely since they are not rigid structures and can move if any trans mission towers experience slight leaning. Homes and mid- rise office buildings may be unsafe for occupancy if the soil loses substantial strength.
CHANGES IN POPULATION AND LAND USE DEVELOPMENT
Seismic Shaking
Based on the current Aliso Viejo Housing Element, it is not anticipated that population patterns will change drastically over the next 20 years. While this may also be true concerning land use and development, if a strong earthquake impacts the city, there is the potential that older structures of the city may be impacted more severely than newer structures and developments in the city.
Liquefaction
Liquefaction is being monitored throughout hazard prone areas in the city, the impacts can cause damage to structures located within these zones. However, these zones are generally located in certain areas of the city, meaning that the damage potential is limited to these areas. Despite this potential, liquefaction is unlikely to cause changes in population patterns . However, land use designations and new development may be limited in these areas out of precaution, or subject to policies developed in City documents such as the LHMP, Land Use, Housing, and Safety Elements. The City’s development review process will identify steps to mitigate or prevent future liquefaction events.
WILDLAND/URBAN FIRES
PHYSICAL THREAT
Structures and physical assets in Aliso Viejo that are not equipped with fire suppression technology or design features that mitigate fire vulnerability are at risk of fire. Generally, these buildings are older, may not be well maintained, and may not meet current code requirements and regulations. While all structures can be impacted by either wildland or urban fire, older buildings may have increased vulnerability to these hazards.
The California Department of Forestry and Fire Protection has mapped Very High Fire Hazard Severity Zones (VHFHSZ) within both the City’s Local Responsibility Area (LRA) and the State Responsibility Area (SRA). The LRA is a government-designated area where a local agency, city, or county, NOT the State, is responsible for fire protection. An SRA is the opposite, where the State has responsibility for wildland fire protection. Figure 4-3 identifies these zones along with 143
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
76 FIGURE 4-3: CFS AND FOCS LOCATED IN FIRE HAZARD SEVERITY ZONES 144
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
77 the City’s CFs and FOCs located within the area. All structures within this fire zone are at an elevated risk of wildfire impacts. Figure 4-4 identifies Aliso Viejo’s wildland urban interface (WUI) area, including the CF’s and FOC’s located within it, in addition to the historic wildfire perimeters in and around the city. Table 4-6 identifies 1 CFs and four facilities of concern within these zones, which could result in a potential loss of approximately $6 million. While these areas have a high degree of vulnerability to wildfire, other areas of the city may also be susceptible due to ember cast. Sometimes the ignition of a wildfire may occur because of power lines located around overgrown trees, causing a spark, and catching the tree on fire.
SOCIAL THREAT
A fire hazard immediately threatens seniors and persons with disabilities. These groups may have limited mobility or diminished environmental awareness. For example, a senior who lives alone may not know if a fire ignites in their house until a room fills with smoke or a flashover occurs, at which point escape may be more difficult or impossible. Therefore, a fire that starts in or spreads to senior residences in Aliso Viejo could be highly threatening to those populations. Persons with disabilities may require special mobility devices or caregiver assistance to evacuate, which may not be readily available when a fire occurs. Other groups with increased threat levels include lower-income people and renters. These individuals may live in substandard housing with outdated materials that are known to be flammable. Renters and lower -income people may also live in housing units with improperly designed or unmaintained electrical or heating systems that could cause a fire. These groups may not possess the financial resources to rebuild their homes or relocate to new homes after a wildland or urban fire.
Aliso Viejo has a sizable portion of its residents located in the LRA, primarily within the City's western and southern portions in the community. Table 4-7 shows us that approximately 21.6% of the City’s population is located within Aliso Viejo’s LRA and the identified VHFHSZ. Of these households, the vulnerable populations represent approximately 12.9% of these households as having at least one person living there with a disability, 2.4% of these households live under the poverty limit, and 23.4% of these households have one-member aged over 65+; however, these households have a much higher median income than the City as a whole.

79 Aliso Viejo also has a sizeable portion of its residents located within the Wildland Urban Interface (WUI). Table 4-8 shows us that approximately 71.4% of the City’s population is located within Aliso Viejo’s WUI . Of these households, the vulnerable populations represent approximately
13.0% of these households as having at least one person living there with a disability, 4.8% of these households live under the poverty limit, and 17.7% of these households have one-member aged over 65+; however, these households have a slightly higher median income than the City as a whole.
OTHER THREATS
Wildfires and urban fires can consume power lines and force utility operators to shut off electrical and gas transmission activity, leading to utility outages in Aliso Viejo homes and businesses. Any streets surrounded by blazes or blocked by burning debris would hinder transportation, prevent victims from escaping, and block emergency response crews from reaching the source of the fire.
Anyone living towards the end of a cul-de-sac faces an elevated threat of being trapped if the fire occurs or spreads to the mouth of the street. Fires that destroy trees or vegetation (especially within parks and open space areas) could limit or prevent the use of these areas affecting Table 4-7: Very High Fire Hazard Severity Zone Threatened Populations Threatened Population Metrics LRA -

80 recreational opportunities for residents. Public Safety Power Shutoffs (PSPS) are a significant issue for many communities throughout California. There is one such circuit that can affect the city and has the potential for large-scale impacts to residents. In the event of a PSPS outage in neighboring cities near Aliso Viejo, the City’s resources could be strained as residents of affected areas seek refuge in communities that have power. Outreach to residents and businesses to help them understand and prepar e for these events will be an important aspect of the City’s overall hazard mitigation strategy.
CLIMATE CHANGE VULNERABILITY
Climate change will likely increase the city’s vulnerability to wildfire impacts because of increasing temperatures, which could change the moisture content of plant materials and potential increase future drought conditions.
CHANGES IN POPULATION PATTERNS AND LAND USE DEVELOPMENT If a large wildfire were to occur, it is feasible that changes to population patterns could fluctuate.
Future land use designations, re-development, or new development in these areas could be restricted or even prohibited, especially in the WUI and the VHFHSZ’s. The anticipated lack of population growth in the city over the next 20 years is not expected to have a significant impact on Aliso Viejo’s vulnerability to wildfire.
HUMAN-CAUSED HAZARDS (MASS CASUALTY INCIDENT (TERRORISM), CYBER
THREAT)
PHYSICAL THREAT
Terrorism/Mass-Casualty Incident
There is no way to predict which of Aliso Viejo’s facilities or assets may be impacted by a mass casualty incident/act of terrorism since the motivation behind the incident is often complex and not easily understood. Generally, these types of incidents occur at places of political, economic, or cultural importance. If the perpetrator's motives are to shut down city or regional government activity for a period, they may instead target pieces of infrastructure, like water systems, utility delivery systems, or transportation networks. In this situation, bridges may become prime locations for these types of activities. The financial losses that may result would depend on the degree of destruction associated with the activity. If the incident involves the destruc tion of physical assets, the cost to the City or property owners in Aliso Viejo could be significant.
Cyber Threat
Cyber threats would have a limited impact on physical assets. The extent of this impact would focus on City-owned computer and network infrastructure.
SOCIAL THREAT
Terrorism/Mass-Casualty Incident
Since mass casualty incidents/acts of terrorism could occur anywhere in Aliso Viejo , all groups are potentially threatened by the impacts of these incidents; however, the extent of the threat would depend upon the type and magnitude of the event. For example, an active shooter situation may be isolated to a single location, whereas a larger-scale incident may affect multiple locations.
Some locations are more likely to be targeted than others, including but not limited to medical facilities, government buil dings, or financial institutions. Populations that frequently visit these areas may face a greater threat than the average person. Seniors, pregnant women, and persons with disabilities, for instance, are more likely to frequently visit the local medical f acilities than other subpopulations in the city. If an incident occurs at a medical facility or within the community 148
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
81 (overwhelming medical resources), these groups are expected to face an increased impact from the incident.
An incident that occurs at a government building or financial institution may be more likely to threaten seniors or lower-income individuals that rely on in-person transactions in place of online options. As such, their use of these in-person services may place them in harm’s way. An incident that occurs at bank locations in the city can be expected to be more of a threat to these groups.
Seniors and persons with limited income may be challenged if there is a need to shelter in place or evacuate during an incident requiring additional services, assistance, and/or medical treatment.
Cyber Threat
Cyber threats may have an impact on residents and businesses throughout the city . While most cyber threats focus on large entities like major corporations and/or government agencies, all residents could become victims of cyber threats. If services affected by cyber incidents become delayed or are impacted, populations that rely on those services may be negatively impacted if no alternatives exist.
CLIMATE CHANGE VULNERABILITY
Climate change has no direct link to human-caused hazards and is not anticipated to increase the city’s vulnerability at this time.
CHANGES IN POPULATION PATTERNS AND LAND USE DEVELOPMENT The hazards identified under human-caused hazards will not affect population patterns or land use and development, as no connection can be drawn between these hazards and changes in population patterns or land use and development.
SEVERE WEATHER (WINDSTORM, WINTER/COASTAL STORMS)
PHYSICAL THREAT
Windstorm
Intense winds likely present the greatest threat to physical structures, particularly from trees or branches that fall on buildings and cause substantial damage. Older structures that have deferred maintenance or have not been retrofitted for high wind conditions may suffer greater damage than newer/updated structures. Utility lines and wooden utility poles face an elevated threat from wind, as do buildings without reinforced roofs.
Winter/Coastal Storms
There is no indication that rainfall or severe rain hazards will abate either in Aliso Viejo or the greater region of Southern California in the future. While Aliso Viejo may experience prolonged periods of dry or wet years, all expectations are that they will continue and increase severity. Rain could damage any structures with poorly constructed roofs and could also erode the soil around building foundations. Heavy rain could also lead to flooding, which would damage unelevated structures in flood zones. Landslides triggered by heavy rains would damage any structures located below the landslide’s starting point.
SOCIAL THREAT
Windstorm
Severe wind events can harm people throughout Aliso Viejo but have a greater effect on the safety of people experiencing homelessness and people who work outdoors. Lower -income 149
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
82 residents, who may not have the financial resources to purchase homes built or retrofitted to withstand powerful winds, could also have difficulty recovering from wind events.
Winter/Coastal Storms
Severe storms pose a threat to any groups in Aliso Viejo who cannot access adequate shelter.
Homeless people often live in tents or other informal structures that may protect against minor rains but are inadequate against heavy rain events. Heavy rain can lead to flooding, which could inundate or sweep away any informal dwellings. Additionally, vulnerable populations living in older homes with outdated building materials may experience damage during significant rain events. If affected groups have limited incomes or lack the resources to make necessary repairs or maintain the structures, retrofit of these structures may be hindered.
OTHER THREATS
Windstorm
The potential for windstorms to create a financial strain on both the public and the City exists in the event of utility infrastructure damage or loss of power. These windstorms can uproot trees and landscaping, further burdening the owners to replace or r epair the losses. Trees located in City parks may also be damaged or destroyed. Air quality can also be affected by these wind events, stirring up dust, pollen, debris, etc. Another threat associated with severe wind is wildfire impacts (discussed earlier) and the recent practice of electric utilities conducting Public Safety Power Shutoff activities. These shutoffs may affect electrical services during high wind events in parts of southern California. The City has one PSPS circuit that could affect power service to the City should it be activated to avoid a potential wildfire. PSPS circuits located in other parts of the County and region could impact the city in other ways , such as people relocating to Aliso Viejo temporarily due to power loss.
Winter/Coastal Storms
The potential for winter/coastal storms to create a financial strain on both the public and the City exists in the event of utility infrastructure damage and loss of power. Damage to roadway networks including bridges can interrupt effective transportation throughout the city , possibly hindering emergency equipment and first responder response capability. Major storm events can even impact the effectiveness of the evacuation capacity of the roadway network into and out of the City.
CLIMATE CHANGE VULNERABILITY
Windstorm
Climate change will likely increase the city’s vulnerability to severe weather impacts associated with the anticipated increase in future storm intensity and frequency, as well as increases in future temperatures.
Winter/Coastal Storms
Climate change is anticipated to change precipitation patterns and could cause greater incidence of extreme temperatures. If more intense storm events occur as a result or events change in frequency, portions of the City vulnerable to these conditions could experience greater impacts.
CHANGES IN POPULATION AND LAND USE DEVELOPMENT
Windstorm
Severe windstorms occur periodically (primarily during the Fall months) and generally do not affect populations to the degree that they would need to migrate in and out of the city.
It is unlikely that severe wind will affect land use and development because the development review process will take steps to mitigate or minimize the impacts of severe wind. There is the 150
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
83 potential that older structures in the northern part of the city may be impacted more severely than newer structures in the southern part of the city. The northern part of the city has overhead powerlines and mature trees, and older structures may not comply with current building codes.
The anticipated lack of population growth in the city over the next 20 years is not expected to have any impact on Aliso Viejo’s vulnerability to windstorms.
Winter/Coastal Storms
Based on the Housing Element, it is not anticipated that population growth patterns will change over the next 20 years.
It is unlikely that winter/coastal rainstorms will affect land use and development because the development review process will take steps to mitigate or minimize impacts from severe rainstorms. The City has invested significantly in its stormwater management infrastructure, which should protect much of the city from the effects of severe rainstorms. The anticipated lack of population growth in the city over the next 20 years is not expected to have any impact on Aliso Viejo’s vulnerability to winter/coastal storms.
LANDSLIDE
PHYSICAL THREAT
Landslides pose a threat to a variety of city and resident owned facilities. Table 4-9 identifies the city facility located within the mapped deep-seated landslide hazard zones. Much of the City is located within these landslide susceptible areas, especially in those areas characterized by steep slopes and canyons, which are vulnerable to landslides during long periods of rainfall or seismic events. Figure 4-5 displays these areas of the city along with the mapped CFs and FOCs that could potentially be damaged by landslide events.

SOCIAL THREAT
As shown in Table 4-10, the data set shows that 10,402 residents and 3,644 households are located within the deep-seated landslide hazard zone, which is approximately 11.2% of the city’s population. The median household income is higher in these zones, and the percentage of households living under the poverty limit is lower than the city overall. However, households with at least one person living with a disability is slightly lower, while the percentage of households with one-member aged 65+ is also slightly lower when compared to the city overall.
151
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
84 OTHER THREATS
Landslides may block roadways causing long-term disruptions to the roadway network, infrastructure systems, and city capabilities. Underground utility lines in slide -prone areas or above-ground lines built on or above them can be damaged in a landslide, causing service outages. Landslides could affect sensitive ecological areas around the community, causing localized harm to the region’s ecosystem, although widespread disruptions are unlikely. Homes and businesses are typically damaged or destroyed by landslides. In addition to potentially causing significant injuries or fatalities, this can cause economic harm and create a need for long- term emergency sheltering and temporary housing until these buildings can be reconstructed.
Utility lines, such as power lines or water pipes, may be broken by a landslide, interrupting important services.
CLIMATE CHANGE VULNERABILITY
Climate change could indirectly increase the city’s vulnerability to landslide impacts. Increased frequency and intensity of future storms may cause more moisture-induced landslides. Warmer temperatures and more frequent drought conditions may lead to more fires, destabilizing soil on slopes, and making future landslide events more likely.
CHANGES IN POPULATION AND LAND USE DEVELOPMENT
Land sliding is being monitored throughout the hazard prone areas in the city, the impacts can cause damage to structures located within these zones. However, these zones are generally located in certain areas of the city, meaning that the damage potential is limited to these areas.
Despite this potential, landslides are unlikely to cause changes in population patterns. However, land use designations and new development may be limited in these areas out of precaution, or subject to any policies developed in City documents such as the LHMP, Land Use, Housing, and Safety Elements. The City’s development review process will identify steps to mitigate or prevent future landslide events. The anticipated lack of population growth in the city over the next 20 years is not expected to have a significant impact on Aliso Viejo’s vulnerability to landslides.

86 HAZARDOUS MATERIALS RELEASE
PHYSICAL THREAT
Hazardous materials can cause damage to physical assets in Aliso Viejo if they are released into the environment. Corrosive hazardous materials can damage building exteriors of CFs or FOC s.
Flammable hazardous materials can potentially start fires and may cause any CFs or FOC s nearby to flashover and ignite. Generally, sites closer to the origin for the release of hazardous materials are threatened greater than those further away.
Table 4-11 shows the numbers of physical assets in Aliso Viejo threatened by a hazardous materials release within 500 feet of a site storing or using hazardous materials. There are 4 CFs composed of Vital City Operations located within 500 feet of a site with hazardous materials and 5 FOC within 500 feet of a site with hazardous materials. The total potential loss estimated for these locations is approximately $41.6 million. Figure 4-6 depicts these sites in relation to CFs and FOCs within the City.

Other Facilities of Concern** 0 5 $ -
Total 4 5 $ 41,673,906
* Based on the City of Aliso Viejo insured replacement values **Replacement Values are unavailable as they are not City owned.
SOCIAL THREAT
The threat of a hazardous materials release event affects those closest to a source of hazardous materials, including industrial sites, gas stations, gas transmission lines, or sewer mains. Table 4-12 shows the City’s vulnerable populations living within 500 feet of hazardous materials storage/waste sites. These site types, the median household income is approximately $12 ,000 less than the rest of the city. This suggests that more impoverished populations may be living near hazardous materials locations, indicating potential environmental justice concerns should be considered. This data also suggests lower percentages of households with at least one person living with a disability, higher percentages living under the poverty limit, and much higher percentages of households with one member aged 65+.
Aliso Viejo residents living next to major transportation infrastructures, such as highways or major arterial streets, also face a greater threat of being affected by a release of hazardous materials since vehicles transporting hazardous materials may release their contents into the environment if involved in a collision. Specifically, residents in Aliso Viejo living near the major transportation corridor running through the city (SR-73) are at greater risk of exposure from transportation- related hazardous material release than residents living in other parts of the city.
Groups such as the elderly, low-income persons, or renters face a greater risk of exposure since they may not have the financial resources necessary to retrofit their homes against infiltration by hazardous materials or move away to a home that is further from the potential sources of hazardous materials release events. Additionally, any public and private schools, preschools, and residential care and skilled nursing facilities located in this area are at risk of being impacted.
154
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
87 OTHER THREATS
Hazardous materials release could threaten the City’s, and potentially the region’s, transportation networks. Large areas of the local road may be closed to keep people away from areas contaminated with hazardous materials to allow remediation and cleanup activities to occur. If a highly corrosive hazardous material is released, it could potentially cause significant damage to the exteriors of any homes or businesses in the area surrounding the release. Hazardous materials could also harm the City’s urban forest, resulting in the premature death of vegetation in the affected areas.
CLIMATE CHANGE VULNERABILITY
Climate change could indirectly increase the city’s vulnerability to hazardous materials release impacts as climate-related hazard events occur. Precipitation events with increased intensity causing flooding or overwhelming infrastructure could cause an increase in hazardous materials release. Climate-related hazards could also exacerbate the effects and impacts of such events.
For example, heavier rains could lead to more runoff from a contaminated site with hazardous materials.
CHANGES IN POPULATION AND LAND USE DEVELOPMENT
A change in population pattern would only occur if a hazardous materials release was severe enough to require people to move. It is unlikely that hazardous materials release will affect land use and development because the development review process will take steps to mitigate or minimize impacts from a hazardous materials release event. Locations that store, produce, and dispose of hazardous materials are highly regulated within the city and monitored regularly.
Through this process, as well as the development review process, it is not anticipated that land use and development patterns will change. The anticipated lack of population growth in the city over the next 20 years is not expected to have a significant impact on Aliso Viejo’s vulnerability to hazardous materials release.

89 FLOOD
PHYSICAL THREAT
Any physical assets located within these mapped boundaries could be inundated if enough precipitation were to fall, exceeding the storm drain infrastructure design capacity in these areas.
Electronic or mechanical equipment on the ground could become waterlogged and nonfunctional.
Aliso Viejo is extremely fortunate in comparison to other cities, as they have no CFs and only 2 FOCs located within any mapped FEMA flood zones. Table 4-13 depicts these statistics for both the 100-Year and 500-Year FEMA Flood zones.
SOCIAL THREAT
Floodwaters in these areas, both the 100-year zone and the 500-year zone, are anticipated to rise to a depth of no more than one foot. Flooding of this type would likely inundate curb cuts and sidewalks to some extent. People who walk or bike as their primary form of transportation may encounter difficulties if they do not have access to an alternative means of transportation. Seniors, persons with disabilities, and low -income persons are also likely to be threatened. Additionally, persons experiencing homelessness who are outside during flood conditions may experience property damage or may not be able to access shelter. Though floodwaters in Aliso Viejo are not expected to exceed a depth of one foot, six inches of floodwater may render any makeshift structures uninhabitable during the flood event. Possessions such as sleeping bags or electronic devices may be damaged or swept away by the floodwaters.
OTHER THREATS
Flooding may temporarily stop any type of transportation in the city. Debris carried by floodwaters can block roadways, hinder access for vehicles, and potentially affect emergency response services. One foot of rushing water is enough to carry small vehicles. A severe flood situation may prevent people who own smaller vehicles from driving to work, leading to reduced economic activity. Severe flooding that causes serious damage to homes and businesses may also reduce economic activity until repair work is completed.
CLIMATE CHANGE VULNERABILITY
Climate change will likely increase the city’s vulnerability to flooding impacts associated with the anticipated increase to the intensity and frequency of local, regional, and global weather patterns, intensifying atmospheric rivers. This can increase the likelihood of an exceptional rain event in Aliso Viejo that could overwhelm the capacity of flood control infrastructure. Droughts are also Table 4-13: Critical Facilities and Facilities of Concern located in FEMA Flood Zones

City of Aliso Viejo 2024 Local Hazard Mitigation Plan
90 expected to increase in length and frequency due to climate change. Soils dried by extensive drought periods are less able to absorb and drain water, likely increasing flood potential.
CHANGES IN POPULATION AND LAND USE DEVELOPMENT
Given the lack of residents residing in FEMA flood zones it is highly unlikely that flooding will affect the City’s population patterns and growth. It is also unlikely that flooding will affect land use and development patterns because the development review process ensures flood related impacts are mitigated or minimized. The anticipated lack of population growth in the city over the next 20 years is not expected to have a significant impact on Aliso Viejo’s vulnerability to flooding.

92 CHAPTER 5 – HAZARD MITIGATION STRATEGY
STRATEGY DEVELOPMENT PROCESS
Aliso Viejo’s hazard mitigation strategy is a comprehensive set of actions intended to reduce the impact of hazard events. These hazard mitigation actions will help protect the safety and well -being of residents , visitors, CFs and FOC s, other buildings and structures, key services, the local economy, and other important community assets. Some actions will also help with emergency preparedness, allowing for a more effective community response to hazard events. Preparedness actions are not a required component of an LHMP, but they support and compl ement mitigation activities. The HMPC chose to include them as part of the overall hazard mitigation strategy.
USE OF HAZARD AND THREAT ASSESSMENT
The HMPC relied partly on the hazard profiles and threat assessments in this Plan to develop the mitigation strategy's actions. A comprehensive set of mitigation actions was prepared to respond to the relevant hazard situations and protect residents, businesses, and community assets in Aliso Viejo. The HMPC ensured that the mitigation actions w ould help reduce damage from the most frequent types of hazard events, the most significant that may reasonably occur, and those with the greatest potential to harm the community. The HMPC also drafted mitigation actions to help protect the most vulnerable community members and the most vulnerable local assets.
CAPABILITIES ASSESSMENT
As part of the effort to draft mitigation actions, the City completed a capabilities assessment, which included reviewing existing policies, personnel, and technical resources to support hazard mitigation activities in Aliso Viejo. The hazard mitigation actions build off the se resources' existing success and leverage their capabilities to support improved resiliency in the community. The capabilities assessment looked at the following types of resources:
Personnel resources: City employees and volunteers, and employees and volunteers at other agencies Plan resources: Advisory or enforceable plans adopted by the City or other agencies Policy resources: Policies adopted and implemented by the City or other agencies Technical resources: Data and tools available to the City Financial resources: Funding mechanisms available to the City that support mitigation activities.
CAPABILITIES IMPROVEMENT/EXPANSION
The ability to expand current mitigation capabilities will generally be reliant upon the budgeting allocated for each department/program for that fiscal year. The level at which these programs may or may not be expanded upon, will be dependent upon the amount of funding received. FEMA 160
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
93 has released a series of guides over the past few years which highlight some of the ways in which jurisdictions can expand mitigation. Some strategies for increasing current mitigation capabilities may include:
1. City should actively identify, adopt, and enforce the most current set of development codes and standards available. Strongly encouraging new development to be constructed to higher standards than currently required, increasing resilience within the community.
2. Engaging parts of the community that may not be actively involved in mitigation efforts.
3. Expanding the number and types of organizations involved in mitigation planning and implementation, increasing both efficiency and bandwidth.
4. Fostering new relationships to bring underrepresented populations and partners to the hazard’s mitigation planning process.
5. During the annual LHMP review, the committee should look for opportunities to fund and expand/enhance the effectiveness of current mitigation actions.
Table 5-1 shows the capabilities assessment for Aliso Viejo. Within each resource described a section titled “Expansion and Improvement” is provided, which helps the City recognize specific areas where each capability may be modified to align with mitigation priorities and actions to be taken in the future.

HAZARD MITIGATION STRATEGIES AND ACTIONS
Hazard Mitigation Goals
The goals identified in Chapter 1 help develop policies to protect community members, ecosystems, and other important assets from hazard events. These goals were developed to ensure consistency with the City’s General Plan Safety Element, which plays an important role in risk reduction within Aliso Viejo. These goals informed the development of mitigation actions and act as checkpoints to help City staff determine implementation progress.
Evaluation of Potential Hazard Mitigation Actions
The HMPC prepared a set of potential mitigation actions based on the hazard profiles, threat assessment, capabilities assessment, comm unity survey results, discussions among HMPC members, and existing best practices. Next, the HMPC evaluated these potential actions using the following criteria:
• FEMA requires local governments to evaluate potential mitigation actions' monetary and non- monetary costs and benefits. While local governments are not required to assign specific dollar values to each action, they should identify the general size of costs and benefits. • The HMPC may elect to include measures with a high cost or low benefits, but such measures should be beneficial to the community and appropriate use of local resources.
Also, FEMA directs local governments to consider the following questions as part of the financial analysis:
• What is the frequency and severity of the hazard type to be addressed by the action, and how vulnerable is the community to this hazard?
• What impacts of the hazard will the action reduce or avoid? • What benefits will the action provide to the community? The HMPC also chose to review and revise the potential hazard mitigation actions using the STAPLE/E (Social, Technical, Administrative, Political, Legal, Economic, and Environmental) criteria (Table 5-2). The HMPC did not formally assess every potential mitigation action under all STAPLE/E criteria but used the criteria to guide and inform the discussion. The HMPC also discussed how the criteria might evaluate grant applications the City may submit to receive funding for LHMP implementation.
170
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
103
Changes to Previous Mitigation Actions
As previously stated in Chapter 1, this is the City of Aliso Viejo’s very first adopted LHMP, therefore there were no previous mitigation actions to update, keep in place, or amend. The mitigation actions created and prioritized for this plan shall become the blueprint for all future iterations of this document and policies designed to mitigate the hazards present within the City. 2023 Hazard Mitigation Strategies and Actions
Table 5-3 identifies the 2023 mitigation strategies and actions proposed by the City as part of this LHMP update process. In addition to the list of actions, the table also identifies potential funding sources, responsible departments, relative cost estimates, timeframes, and priorities for these Table 5-2: STAPLE/E Criteria
Issues Criteria
Social Is the action socially acceptable to Aliso Viejo community members? Would the action mistreat some individuals?
Is there a reasonable chance of the action causing a social disruption? Technical Is the action likely to reduce the risk of the hazard occurring, or will it reduce the hazard's effects? Will the action create new hazards or make existing hazards worse? Is the action the most useful approach for Aliso Viejo to take, given the City and community members' goals? Administrative Does the City have the administrative capabilities to implement the action? Are there existing City staff who can lead and coordinate the measure's implementation, or can the City reasonably hire new staff for this role? Does the City have enough staff, funding, technical support, and other resources to implement the action? Are there administrative barriers to implementing the action? Political Is the action politically acceptable to City officials and other relevant jurisdictions and political entities? Do community members support the action?
Legal Does the City have the legal authority to implement and enforce the action? Are there potential legal barriers or consequences that could hinder or prevent the implementation of the action? Is there a reasonable chance that the implementation of the action would expose the City to legal liabilities? Could the action reasonably face other legal challenges? Economic What are the monetary costs of the action, and do the costs exceed the monetary benefits? What are the start-up and maintenance costs of the action, including administrative costs? Has the funding for action implementation been secured, or is a potential funding source available? How will funding the action affect the City’s financial capabilities? Could the implementation of the action reasonably burden the Aliso Viejo economy or tax base? Could there reasonably be other budgetary and revenue impacts to the City? Environmental What are the potential environmental impacts of the action? Will the action require environmental regulatory approvals? Will the action comply with all applicable federal, state, regional, and local environmental regulations? Will the action reasonably affect any endangered, threatened, or otherwise sensitive species of concern? 171

actions, which are described further below. In addition to mitigation action and strategies, several preparedness activities were identified and denoted with the letter “P.”
Potential Funding Sources
Table 5-3 identifies the potential funding sources that may be used to implement mitigation strategies. These funding sources include the following federal and state sources:
Building Resilient Infrastructure and Communities (BRIC): A competitive FEMA grant program to support states, local communities, tribes, and territories.
Flood Mitigation Assistance Program (FMA): A competitive grant program that provides funding to states, local communities, federally recognized tribes, and territories. Funds can be used for projects that reduce or eliminate the risk of repetitive flood damage to buildings insured by the National Flood Insurance Program.
Hazard Mitigation Grant Program (HMGP): Provides funding to state, local, tribal, and territorial governments to rebuild in a way that reduces or mitigates future disaster losses in their communities. This grant funding is available after a presidentially declared disaster.
Other Grants: Other grants may include State of California grants associated with climate change, water infrastructure, homeland security, transportation, or other funding sources that periodically become available. The list below provides some common sources:
1. Climate Adaptation Planning Sustainable Transportation Planning Grant Program - Department of Transportation
2. Sustainable Communities Competitive – Department of Transportation
3. CAL FIRE Wildfire Prevention Grants Program – Department of Forestry and Fire Protection
4. Integrated Climate Adaptation and Resiliency Program's Climate Adaptation Planning Grant – Office of Planning and Research
5. Small Community Drought Relief Program – Department of Water Resources
6. Addressing Climate Impacts – Department of Fish and Wildlife
7. Cleanup Loans and Environmental Assistance to Neighborhoods (CLEAN) Program – Department of Toxic Substances Control
8. Clean Water State Revolving Fund (CWSRF) Program Construction – State Water Resources Control Board
9. Drinking Water State Revolving Fund (DWSRF) Construction – State Water Resources Control Board
10. Water Recycling Funding Program (WRFP) Construction Grant – State Water Resources Control Board
11. Equitable Community Revitalization Grants (ECRG) – Department of Toxic Substances Control
12. Water Recycling Funding Program (WRFP) Planning Grant – State Water Resources Control Board
13. Infrastructure State Revolving Fund (ISRF) Program - Infrastructure and Economic Development Bank 172

Responsible Department
Table 5-3 includes the identification of key responsible departments that will be focused on future implementation of mitigation strategies and actions identified by the City.
Relative Cost Estimates
The HMPC identified relative cost estimates to meet the hazard mitigation planning process's cost estimation requirements bas ed on their understanding of the mitigation action intent and their experience developing identical or similar programs/implementing projects. Three cost categories based on the City’s typical cost criteria were used for budgeting purposes:
• Low cost ($): $50,000 or less
• Medium cost ($$): $50,001 to $249,999
• High cost ($$$): Greater than $250,000
Timeframes
Table 5-3 includes timeframes that provide general timing durations due to the nature of the mitigation actions identified by the City. The following timeframes are used based on the following conditions:
Ongoing (Annually): Actions that identify this timeframe are the types of actions that City staff would conduct on an annual basis.
Ongoing (As Needed): Actions that identify this timeframe include activities that City staff would conduct in response to a request by internal (City Departments) or external (Property Owners) forces.
Future Planning Process: Actions identified within this timeframe are considered low-priority actions that the City would like to continue to track but does not feel they would be able to implement in the current planning implementation timeframe.
For actions that use these terms, it is intended to identify that the action may add to existing capabilities and not have a particular start or end date or occur periodically. This is typically used for actions that include new policies, tasks, or standard operating procedures intended to mitigate future risks.
Prioritization
As part of the mitigation actions development and review, the HMPC also prioritized the actions. The prioritization efforts l ooked at the risks and threats from each hazard, financial costs and benefits, technical feasibility, and community values. HMPC members were asked to identify their priority actions through a voting exercise. Items are prioritized based on the number of votes the HMPC members receive. Thes e quantitative scores were then converted to qualitative categories of low, medium, and high priority. 173 City of Aliso Viejo 2024 Local Hazard Mitigation Plan

NATIONAL FLOOD INSURANCE PROGRAM
Aliso Viejo participates in the National Flood Insurance Program (NFIP), which was created by Congress in 1968 to provide flood insurance at subsidized rates to homeowners who live in flood-prone areas. Individual communities have the option to participate in the NFIP, although property owners who live in nonparticipating communities with flood-prone areas will not be able to buy flood insurance through the program. Additionally, nonparticipating communities with mapped floodplains cannot receive federal grants or loans for development activities in flood-prone areas and cannot receive federal disaster assistance to repair flood-damaged buildings in mapped floodplains.

Initial Flood Insurance Rate Map (FIRM) 02/18/04
NFIP Participation Date 06/18/09
Current Effective map Date 12/03/09
Although participation is not a dedicated hazard mitigation action, Aliso Viejo will continue to participate in the NFIP and comply with the program’s requirements through continued enforcement of the City’s Floodplain Management Regulations (Municipal Code Chapter 7.50:
Floodplain Management Overlay District).

City of Aliso Viejo 2024 Local Hazard Mitigation Plan 116
These regulations apply to all areas identified as flood-prone within the City. This chapter of the Municipal Code identifies the purpose of the regulation, methods of reducing flood losses, basis for establishing flood hazard areas, development permit requirements, duties and responsibilities of the City’s Floodplain Manager, development standards that apply in flood-prone areas, and required documentation and analysis for construction within these areas. As part of the City’s efforts to comply with NFIP, Aliso Viejo will make updates and revisions to the Floodplain Management regulations to minimize the threat of harm from flood events. These updates and revisions may be promoted by changes in local demographics, shifts in land use, changes to flood regimes such as frequency and intensity of flood events, and other factors that may warrant municipal action. The City will also continue incorporating any changes to mapped flood plains' locations and designations into future planning documents, including future updates to this Plan.
The City of Aliso Viejo contains Special Flood Hazard Areas (SFHA) and participates in the National Flood Insurance Program (NFIP), which currently includes 21 policies in force, amounting to roughly $9,432 in premiums paid annually. The types of uses on these insured properties are currently unknown by the City. Total insurance coverage for these policies amounts to $5,849,000. Aliso Viejo has no repetitive loss properties that FEMA identified; however, they have had a total of 1 closed Paid Losses cases totaling some $4,236.95 in damages paid out. Aliso Viejo is currently not rated on the CRS (Community Rating System). 32 A CRS rating entitles property owners
within the jurisdiction to a discount on insurance rates should their property be located within an SFHA and 5% if it is not. The City’s most current FIRM (Flood Insurance Rate Map) was adopted on December 03, 2009.

CHAPTER 6 – PLAN MAINTENANCE
For this LHMP to remain effective and useful to the community of Aliso Viejo, it must remain up to date. An updated version of the LHMP will continue to guide Aliso Viejo’s hazard mitigation activities and help keep the City eligible for state and federal hazard mitigation funding. The HMPC has structured this LHMP so individual sections can easily be updated as new information becomes available and new needs arise, helping to keep this Plan current.
This chapter discusses updating this Plan to comply with applicable state and federal requirements. This chapter also describes how the City can incorporate the mitigation actions described in Chapter 5 into existing programs and planning mechanisms and how public participation will remain an important part of Plan monitoring and future update activities.
COORDINATING BODY
The HMPC will remain responsible for maintaining and updating the Plan, including evaluating the Plan's effectiveness as needed. Members of the HMPC will also coordinate the Plan's implementation through their respective positions. Table 1-1 contains a list of current members.
In future years, staff and representatives (either current HMPC members or other individuals) from the following departments, districts, and agencies should be included in maintenance and update activities:
• Building and Safety
• City Clerk
• City Manager
• Code Enforcement
• Emergency Management
• Financial Services
• Fire Services
• Human Resources
• Information Technology
• Planning Services
• Police Services
• Public Works
• Public Information Officer
• Recreation & Community
Services
The staff member currently serving as the HMPC leader (the person responsible for coordinating future updates) is the Orange County Sheriff Department, Senior Emergency Management Program Coordinator. They will serve as the project manager during the updat e process or designate this role to another staff member. The HMPC leader or their designee will coordinate maintenance of this Plan, lead the formal Plan review and evaluation activities, direct the Plan update, and assign tasks to other members of the HMPC to complete these activities. Such tasks may include collecting data, developing new mitigation actions, updating mitigation actions, making presentations to City staff and community groups, and revising the Plan sections.
PLAN IMPLEMENTATION
The Plan's effectiveness depends on the successful implementation of the mitigation actions.
Implementation includes integrating mitigation actions into existing City plans, policies, programs, and other implementation mechanisms. The mitigation actions in this Plan are intended to reduce the damage from hazard events, help the City secure funding, and provide a framework for hazard mitigation activities. HMPC members prioritized the hazard mitigation actions in Table 5-3 in Chapter 5. These priorities will guide the implementation of these actions through new or existing City mechanisms as resources are available. The LHMP project manager is responsible for overseeing the implementation, promotion, and maintenance of this Plan and facilitating meetings and coordinating activities related to Plan implementation and maintenance. 185
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
118
The key City Plans that should incorporate content from this LHMP include:
• Aliso Viejo General Plan Safety Element – This element should incorporate relevant mapping and analysis in the Safety Element to ensure this plan's goals and policies are reinforced throughout future developments and projects proposed within the city. • Aliso Viejo Emergency Operations Plan – The EOP focuses on the effective preparedness and response to hazard events within the c ity. Incorporating relevant content from this plan into the EOP ensures consistency regarding the hazards addressed in both plans.
• Aliso Viejo Capital Improvements Program – The CIP identifies key infrastructure investments throughout the c ity, including hazard mitigation elements. Incorporati ng this plan into the CIP may enhance infrastructure investment through additional funding and/or modification of improvements to include hazard mitigation elements.
This integration of the LHMP into the Aliso Viejo General Plan also allows the City to comply with AB 2140 requirements, as identified in Chapter 1 of this plan.
FUTURE PLAN INTEGRATION
Integration of the Aliso Viejo LHMP into other plans is expected to occur either annually or on an as needed basis. The following are basic assumptions for these two categories:
Annual Integration – this is expected to occur with activities like Annual Budget Action Planning where a Department identifies priorities for the upcoming year and initiative to be achieved.
As Needed Integration – this is expected for updates to existing plans or the creation of new plans that should be connected to the LHMP. When existing plans like the General Plan, EOP, or CIP are updated information from this plan should be incorporated where applicable. When these updates occur, new relevant information should also be incorporated back into the LHMP ensuring greater consistency.
PLAN MAINTENANCE PROCESS
The City’s plan maintenance process will rely on the Aliso Viejo Mitigation Implementation Handbook, located in Appendix E . The handbook is intended to function as a stand-alone document that gives concise and accessible guidance to staff to implement and maintain the Plan.
A key component is the specific mechanisms that the City can use to integrate this plan into the other City planning mechanisms.
PLAN MONITORING AND EVALUATION
When members of the HMPC are not updating the Plan, they should meet at least once a year to go over mitigation action implementation and evaluate the Plan’s effectiveness. These meetings should include:
• Discussion of the timing of mitigation action implementation • Mitigation action implementation evaluation and determination of success • Mitigation action prioritization revisions, if deemed necessary • Mitigation action integration into other mechanisms, as needed The first of these meetings will be held in the 2023 -2024 fiscal calendar year. To the extent possible, HMPC meetings should be scheduled at an appropriate time in the City’s annual budgeting process, which will help ensure that funding and staffing needs for mitigation actions are considered.
When the HMPC meets to evaluate the Plan, members should consider these questions:
186
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
119
• What hazard events, if any, have occurred in Aliso Viejo in the past year? What were the impacts of these events on the community? Were the impacts mitigated, and if so, how?
• What mitigation actions have been successfully implemented? Have any mitigation actions been implemented but not successfully, and if so, why? • What mitigation actions, if any, have been scheduled for implementation but have not yet been implemented?
• What is the schedule for implementing future mitigation actions? Is this schedule reasonable? Does the schedule need to be adjusted for future implementation, and are such adjustments appropriate and feasible?
• Have any new concerns arisen, including hazard events in other communities or regions not covered by existing mitigation actions?
• Are new data available to inform the Plan's updates, including data relevant to the hazard profiles and threat assessments?
• Are there any new planning programs, funding sources, or other mechanisms to support hazard mitigation activities in Aliso Viejo?
• Is our approach to outreach connecting with vulnerable populations?
PLAN UPDATES
The information in this Plan, including the hazard profiles, threat assessments, and mitigation actions, is based on the best available information, practices, technology, and methods available to the City and HMPC when this Plan was prepared. As factors change, including technologies, community demographics and characteristics, best practices, and hazard conditions, it is necessary to update the Plan to remain relevant. Additionally, Title 44, Section 201.6(d)(3) of the Code of Federal Regulations requires that LHMPs be reviewed, revised, and resubmitted for approval every five years to remain eligible for federal benefits.
UPDATE METHOD AND SCHEDULE
The update process will begin no later than four years after this Plan is adopted, allowing a year for the update process before the Plan expires. However, it is recommended that you begin the update process three years after plan adoption if the funding source for the plan will be a mitigation grant. Depending on the circumstances, the LHMP project manager or their designee may also choose to begin the update process sooner . Some reasons for accelerating the update process may include:
• A presidential disaster declaration for Aliso Viejo or an area that includes part of or the entire City.
• A hazard event that results in one or more fatalities in Aliso Viejo.
The update process will add new and updated methods, demographic data, community information, hazard data and events, considerations for threat assessments, mitigation actions, and other necessary information, keeping the Plan relevant and current. The HMPC will determine the best process for updating the Plan, which should include the following steps: 187 City of Aliso Viejo 2024 Local Hazard Mitigation Plan
120
UPDATE ADOPTION
The Aliso Viejo City Council is responsible for adopting this Plan and all future updates. As previously mentioned, adoption should occur every five years. The City should begin the update process at least one year before expiration to ensure the plan remains active. If the City has a grant application that relies on the LHMP, an update to the plan should occur no later than 18 months before expiration. Adoption should take place after FEMA notifies the City that the Plan is Approved Pending Adoption. Once the City Council adopts the Plan following FEMA's approval, the adopted plan should be transmitted to FEMA.
CONTINUED PUBLIC INVOLVEMENT
The City will continue to keep members of the public informed about the HMPC’s actions to review and update the LHMP. The HMPC will develop a revised community engagement strategy that reflects the City’s updated needs and capabilities. The updated strategy should include:
• A tentative schedule and plan for public meetings , where input and feedback can be provided from residents, property owners, and businesses. • Recommendations for using the City website and social media accounts, • Content for public outreach documentation.
• The HMPC will also develop a short (3-5) question online survey that can be shared with the community to gather additional input during the implementation period, ensuring that the cities vulnerable populations are accommodated during this process The HMPC will then incorporate this content into the annual progress updates currently provided to the City Council. The HMPC or City Staff will then provide this information on the LHMP Webpage. When this update becomes available, the City will use its existing social media platforms and mailing lists to engage community members. These outreach opportunities will describe the actions taken by the City and ways that residents, property owners, and businesses can help further the City’s goals. This informati on can also be provided to the Aliso Viejo Engage the Hazard

WHAT IS THIS HANDBOOK?
The Local Hazard Mitigation Plan (LHMP) for the City of Aliso Viejo features an evaluation of the City's hazards as well as a variety of corresponding mitigation actions. These actions are intended to preserve public safety, maintain critical municipal government operations and services when hazard events emerge, and empower community members to take on haz ard mitigation at an individual level. This Implementation Handbook (Handbook) is intended for use by City staff and decision-makers after the LHMP is adopted. It will:
Give clear instructions following the adoption of the LHMP.
Simplify future updates to the LHMP.
Assist the City in preparing grant funding applications related to hazard mitigation.
Guide annual plan review actions.

WHAT TO DO WHEN A DISASTER HAS BEEN PROCLAIMED OR
DECLARED
Disasters may be proclaimed or declared by the Aliso Viejo City Council, the State of California, or the federal government. Responsibilities may differ depending on who proclaims or declares the disaster. If multiple organizations proclaim or declare a disaster, consult all applicable lists.
The Aliso Viejo City Council
If the Aliso Viejo City Council (or the Director of Emergency Services, if the City Council is not in session) proclaims a Local Emergency, take the following steps:
Update Attachment 1 with information about the disaster. Include information about cumulative damage, including any damage outside of Aliso Viejo.
Discuss opportunities for local assistance with the representatives from the California Office of Emergency Services (Cal OES).
If the disaster damages local infrastructure or City-owned facilities, repair or rebuild the structure to be more resilient, following applicable hazard mitigation actions. A list of actions, organized by hazards, is included in Attachment 4.
Chapter 6 of the Aliso Viejo LHMP states that the City should consider updating the LHMP if a disaster causes a loss of life in the community, even if there is no state disaster proclamation or federal disaster declaration that includes part or all of the city. If there is a loss of life in Aliso Viejo, consider updating the LHMP. Consult the section on updating the LHMP in this Handbook for details.
T
he County of Orange
If the County of Orange proclaims a Local Emergency, or a County wide disaster, take the following steps:
Update Attachment 1 with information about the disaster. Include information about cumulative damage, including any damage outside of Aliso Viejo.
Collaborate with the County of Orange Emergency Management Division to assess the damage from the event.
Discuss opportunities for local assistance with the representatives from the California Office of Emergency Services (Cal OES).
If the disaster damages local infrastructure or City-owned facilities, repair or rebuild the structure to be more resilient, following applicable hazard mitigation actions. A list of actions, organized by hazards, is included in Attachment 4.
Chapter 6 of the Aliso Viejo LHMP states that the City should consider updating the LHMP if a disaster causes a loss of life in the community, even if there is no state disaster proclamation or federal disaster declaration that includes part or all of the city. If there is a loss of life in Aliso Viejo, consider updating the LHMP. Consult the section on updating the LHMP in this Handbook for details.

The State of California
If the State of California proclaims a disaster for Aliso Viejo, or an area that includes part or all of Aliso Viejo, take the following steps:
Update Attachment 1 with information about the disaster. Include information about cumulative damage, including any damage outside of Aliso Viejo.
Collaborate with representatives from Cal OES to assess the damage from the event.
Discuss opportunities for local assistance with representatives from Cal OES.
If the disaster damages local infrastructure or City-owned facilities, repair or rebuild the structure to be more resilient, following applicable hazard mitigation actions. A list of actions, organized by hazards, is included in Attachment 4.
If the disaster may escalate into a federal disaster declaration, begin any necessary coordination with representatives from the Federal Emergency Management Agency (FEMA).
Chapter 6 of the Aliso Viejo LHMP states that the City should consider updating the LHMP if a disaster leads to a state disaster proclamation or federal disaster declaration that includes part or all of Aliso Viejo, even if there is no loss of life. Consider updating the LHMP.
Consult the section on updating the LHMP in this Handbook for details.
The Federal Government
If the federal government declares a disaster for Aliso Viejo, or any area that includes part or all of Aliso Viejo, take the following steps:
Update Attachment 1 with information about the disaster. Include information about cumulative damage, including any damage outside of Aliso Viejo.
Collaborate with Cal OES and FEMA representatives to assess the damage.
Determine if Aliso Viejo will be eligible for public assistance funds related to the federal disaster declaration. These funds can be used to reimburse the City for response and recovery activities. If the City is eligible, work with FEMA and Cal OES representatives to enact the necessary requirements and receive funding.
If the disaster damages local infrastructure or City-owned facilities, repair or rebuild the structure to be more resilient, following applicable hazard mitigation actions. A list of actions, organized by hazards, is included in Attachment 4.
The Hazard Mitigation Grant Program (HMGP) is a FEMA program that helps fund hazard mitigation activities after a disaster event. Aliso Viejo may be eligible for funding because of the federal disaster declaration, although not all activities may meet the program 's requirements. If Aliso Viejo is eligible, work with FEMA to apply for this funding.
Chapter 6 of the A
liso Viejo LHMP states that the City should consider updating the LHMP if a disaster leads to a state disaster proclamation or federal disaster declaration that includes part or all of Aliso Viejo, even if there is no loss of life. Consider updating the LHMP.

I WANT TO APPLY FOR MITIGATION GRANT FUNDING
There are three potential grant funding programs that FEMA administers for hazard mitigation activities. Two of these programs, the Building Resilient Infrastructure and Communities (BRIC) and Flood Mitigation Assistance (FMA) funding sources, are available to communities with an LHMP that complies with FEMA guidelines and has been adopted within the past five years. The third funding program is the Hazard Mitigation Grant Program (HMGP), which is available for communities that are part of a federal disaster declaration. This section discusses the BRIC and FMA programs and how to apply for them. The HMGP is discussed under the "Federal Government" subsection of the above "What to Do When a Disaster Has Been Proclaimed or Declared" section.
Building Resilient Infrastructure and Communities (BRIC) Building Resilient Infrastructure and Communities (BRIC) will support states, local communities, tribes, and territories as they undertake hazard mitigation projects, reducing the risks they face from disasters and natural hazards. BRIC is a FEMA pre-disaster hazard mitigation program that replaced the Pre-Disaster Mitigation (PDM) program.
The BRIC program's guiding principles are supporting communities through capability- and capacity- building; encouraging and enabling innovation; promoting partnerships; enabling large projects; maintaining flexibility; and providing consistency.
D
evelopment projects must be identified in a hazard mitigation plan that meets FEMA guidelines and has been adopted within the past five years. When applying to this program, review the list of hazard mitigation actions in Attachment 4 to see which projects may be eligible. Planning efforts for communities that lack a valid hazard mitigation plan may be eligible for funding if the effort would create a valid hazard mitigation plan. All BRIC grant applications are processed through the State.
To learn more, consult with Cal OES representatives or visit the FEMA webpage for the program.
At the time of writing, this webpage is available at https://www.fema.gov/grants/mitigation/building- resilient-infrastructure-communities.
TAKE THE FOLLOWING STEPS TO APPLY FOR BRIC FUNDING:
Confirm that the program is currently accepting funding applications. Check with representatives from Cal OES or consult the Cal OES webpage on the BRIC program. At the time of writing, this webpage is available at
https://www.fema.gov/grants/mitigation/building-resilient-infrastructure-communities.
Identify the actions from the hazard mitigation strategy (see Attachment 4) that call on the City to pursue funding or list grants as a potential funding source. Confirm that the actions are consistent with the requirements of the BRIC grant.
Coordinate with Cal OES representatives to compile and submit materials for the grant application.
Flood Mitigation Assistance
The FMA grant program is a competitive, national program that awards funding for physical development projects and planning efforts that mitigate against long-term damage from flooding. The funding is only available to communities participating in the National Flood Insurance Program (NFIP), which Aliso Viejo currently does. Communities must also have a valid hazard mitigation plan that meets FEMA guidelines to be eligible, and all projects must be consistent with the list of actions in the hazard mitigation strategy. When applying to this program, review the list of hazard mitigation 234
City of Aliso Viejo 2024 Local Hazard Mitigation Plan

actions in Attachment 4 to see which projects may be eligible. As with the BRIC program, applications for the FMA program must be processed through the State. To view more information, consult with Cal OES representatives or visit the FEMA webpage on the program. At the time of writing, this webpage is available at https://www.fema.gov/grants/mitigation/floods.
TAKE THE FOLLOWING STEPS TO APPLY FOR FMA FUNDING:
Confirm that the program is currently accepting funding applications. Check with representatives from Cal OES or consult the Cal OES webpage on the FMA program. At the time of writing, this webpage is available at
https://www.fema.gov/grants/mitigation/floods.
Identify the actions from the hazard mitigation strategy (see Attachment 4) that call on the City to pursue funding or list grants as a potential funding source. Confirm that the actions are consistent with the requirements of the FMA grant.
Coordinate with Cal OES representatives to compile and submit materials for the grant application.

ALISO VIEJO IS GOING THROUGH THE BUDGETING PROCESS
Aliso Viejo's budget process is an ideal opportunity to secure funding for hazard mitigation actions and to ensure that hazard mitigation efforts are incorporated into the City 's fiscal priorities. Aliso Viejo currently operates on an annual budget cycle that runs from July 1st to June 30th.
During this process, City staff should take the following steps to incorporate hazard mitigation into Aliso Viejo's annual budget:
Include hazard mitigation activities into Aliso Viejo's list of Capital Improvement Projects (CIP). Review the list of hazard mitigation actions in Attachment 4 and identify the projects that can be included in the CIP or can support efforts within the CIP.
Review the risk and threat assessments in the LHMP (Chapter 3 and Chapter 4) to ensure that all items in the CIP list are planned, designed, and constructed to minimize the threat from hazard events.
Identify opportunities to identify stand-alone hazard mitigation actions through the annual budget process. Include appropriate items from Attachment 4 in the budget as stand-alone line items, particularly items that the Hazard Mitigation Planning Committee ( Planning Committee) considered a high priority.
Set aside staff to conduct hazard mitigation activities, including time to participate in Planning Committee meetings and research, prepare, and submit BRIC and FMA grant opportunities (consult the "I Want to Apply for Mitigation Grant Funding" section above).
Ensure hazard mitigation activities are reflected in each department's priorities and earmarked time for specific goals.
ALISO VIEJO IS CONDUCTING ITS ANNUAL MEETING OF THE
HAZARD MITIGATION PLANNING COMMITTEE
The hazard mitigation planning process brings together representatives from multiple City departments as well as other relevant stakeholders . It provides a forum to discuss the hazards in Aliso Viejo and how to mitigate them effectively. As mentioned in Chapter 6 of the LHMP, the Planning Committee should meet at least once each year, beginning a year after the LHMP is adopted. During these meetings, the Planning Committee should discuss implementation progress and integration of hazard mitigation actions in other City documents. At these meetings, the Planning Committee can review the status of the hazard mitigation actions and discuss whether completed or in-progress actions are working as expected. These meetings also allow the Planning Committee to strategically plan for the upcoming year.
It may help for the Planning Committee to meet early in the year, in advance of annual budget activities. Attachment 3 contains an example of a Planning Committee Meeting Agenda.
The annual meeting should include representatives from City departments and other organizations that originally prepared the LHMP. Representatives from other relevant organizations should also be invited. During the preparation of the current LHMP, Table 1 was created that includes key staff that participated in the Planning Committee.
In advance of Planning Committee meetings, consider using Attachment 1 to maintain an accurate list of recent disaster events that have occurred in and around Aliso Viejo since the LHMP was adopted. At the Planning Committee meeting, review the Plan Maintenance Table (Attachment 2) to identify any gaps in the LHMP or any other component of the plan that needs updating. This also 236

ALISO VIEJO IS UPDATING ITS POLICY AND REGULATORY
DOCUMENTS
If Aliso Viejo is updating the LHMP, the Safety Element or Housing Element of the General Plan, or the Zoning Code, consult the following applicable section.
Local Hazard Mitigation Plan
All LHMPs should be updated every five years. This helps keep the plan up to date and ensures that it reflects the most recent guidance, requirements, science, and best practices. An updated LHMP also helps keep Aliso Viejo eligible for hazard mitigation grants that require a valid, recent LHMP (see "I Want to Apply for Mitigation Grant Funding"), along with an increased amount of post-disaster recovery funds.
The update process for the LHMP takes approximately one year. To ensure that a new LHMP comes into effect before the previous one expires, the update process should begin no later than 3.5 years after the plan is adopted. Updates may occur sooner at the City 's discretion. Potential reasons for updating the LHMP sooner may include a state disaster proclamation or federal disaster declaration that covers part or all of Aliso Viejo, or if a disaster leads to a loss of life in Aliso Viejo (see the "What to Do When a Disaster Has Been Proclaimed or Declared" section), as discussed in Chapter 6 of the LHMP.
Take the following steps to update the LHMP:
ASSEMBLE THE HAZARD MITIGATION PLANNING COMMITTEE
Convene a Planning Committee meeting no later than 3.5 years after the LHMP is adopted.
Invite the regular Planning Committee members, along with representatives from other organizations that may have a role to play in the update process. 237
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
E-9
Review the current status of mitigation actions, including if there are any that are not being implemented as planned or are not working as expected. Determine if there have been any changes in hazard events, regulations, best practices, or other items that should be incorporated into an updated LHMP.
Decide if there is a need for a technical consultant to assist with the LHMP update and conduct consultant selection activities if needed. If a consultant is desired, the selection process should begin a few months before the update begins.
Create and implement a community engagement strategy based on the strategy prepared for the existing LHMP. Describe in-person and online engagement strategies and materials, including ideas for meetings and workshops, draft community surveys, content for websites and press releases, and other materials that may be useful.
UPDATE THE RISK AND THREAT ASSESSMENTS
Review and update the risk assessment to reflect the most recent conditions in Aliso Viejo.
Consider recent hazard events, new science associated with hazards and climate change, new development and land use patterns, and other recent changes in local conditions.
Evaluate the status of all key facilities. Update this list if new facilities have been constructed or if existing facilities have been decommissioned. Re-assess the threat to key facilities.
Review the demographics of community residents and update the threat assessment for vulnerable populations and other community members.
Assess any changes to the threat to all other community assets, including key services, other facilities, and economic drivers.
U
PDATE THE MITIGATION ACTIONS
Update the existing hazard mitigation actions to reflect actions in progress. Remove actions that have been completed or revise them to increase their effectiveness. Revise actions that have been abandoned or delayed to make them more feasible or remove them from the list of mitigation actions if they are no longer appropriate for Aliso Viejo.
Develop mitigation actions to improve the status of hazard mitigation activities in Aliso Viejo by addressing any issues not covered by the existing LHMP.
The ability to expand current mitigation capabilities will generally be reliant upon the budgeting allocated for each department/program for that fiscal year. The level at which these programs may or may not be expanded upon, will be dependent upon the amount of funding received. FEMA has released a series of guides over the past few years which highlight some of the ways in which jurisdictions can expand mitigation. Some strategies for increasing current mitigation capabilities may include:
City should actively identify, adopt, and enforce the most current set of development codes and standards available. Strongly encouraging new development to be constructed to higher standards than currently required, increasing resilience within the community.
Engaging parts of the community that may not be actively involved in mitigation efforts. Expanding the number and types of organizations involved in mitigation planning and implementation, increasing both efficiency and bandwidth. Fostering new relationships to bring underrepresented populations and partners to the hazard mitigation planning process.
238
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
E-10
During the annual LHMP review, the HMPC should look for opportunities to fund and expand/enhance the effectiveness of current mitigation actions. During annual budgeting processes, the City should identify new funding sources (bonds, grants, assessment districts, etc.) that can be used to support existing capabilities enhancements.
Ensure that the feedback from the community engagement activities is reflected in the new and updated mitigation actions.
REVIEW AND ADOPT THE UPDATED PLAN
Review the other chapters and appendices of the LHMP to reflect any changes made through the update process.
Release the updated plan to the Planning Committee members and revise the plan to reflect any comments by Planning Committee members.
Distribute the updated Plan to any appropriate external agencies not included in the Planning Committee and revise the plan as appropriate in response to any comments.
Release the updated plan publicly for review and make revisions to the plan to reflect public comments.
Submit the plan to Cal OES and FEMA for approval and make any necessary revisions.
Submit the plan to the Aliso Viejo City Council for adoption.
The Safety Element of the General Plan
The Safety Element is a required component of Aliso Viejo's General Plan. It can be updated as a stand-alone activity or as part of a more comprehensive process to update multiple sections or all of the General Plan. The Safety Element does not need to be updated on any set schedule, but updates should be frequent enough for the element to remain cu rrent and applicable to the community.
Local communities can incorporate their LHMP into their Safety Element as allowed under Section 65302.6 of the California Government Code, as long as the LHMP meets minimum federal guidelines. This allows communities to be eligible for an increased share of post-disaster relief funding from the State if a hazard situation occurs, as per Section 8685.9 of the California Government Code.
Take the following steps to incorporate the LHMP into the Safety Element:
I
NCORPORATE NEW REQUIREMENTS INTO THE SAFETY ELEMENT, AND ENSURE THAT THE LHMP IS
CONSISTENT WITH THE SAFETY ELEMENT
Review the requirements for Safety Elements in Section 65302(g) of the California Government Code and for LHMPs in Section 65302.6. Ensure that both documents meet all state requirements.
Ensure that the information in both plans does not contradict each other and that any inconsistencies are corrected to use the most accurate and appropriate information. This information should include a community description, a risk assessment, and a threat assessment.
Ensure that the policies in the Safety Element support the LHMP and provide a planning framework for specific hazard mitigation actions.
239
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
E-11
The Housing Element of the General Plan
The Housing Element is a required component of Aliso Viejo's General Plan. Section 65583 of the California Government Code requires a Housing Element to analyze and plan for new residential growth in a community, including residential growth for households with an annual income below the area median. Like an LHMP, state regulations require the Housing Elements to be updated regularly to remain current and valid.
The Housing Element is not required to contain any information or policies related to hazards, although it may include policies that address retrofitting homes to improve resiliency. However, state law links the regular schedule of Housing Element updates to mandatory revisions to other General Plan elements. For example, Section 65302(g)(2) of the California Government Code requires that communities that update their Housing Element on or after January 1, 2009, also update their Safety Element to include s pecific information and policies related to flood protection. As the LHMP is incorporated into the Safety Element, updates to the Housing Element may indirectly trigger updates to the LHMP.
To update the LHMP concurrent with updates to the Housing Element, take the following steps:
E
NSURE THAT THE LHMP MEETS ANY NEW REQUIREMENTS FOR THE SAFETY ELEMENT THAT MAY BE
TRIGGERED BY A HOUSING ELEMENT UPDATE
Section 65302(g) of the California Government Code lists several requirements for the Safety Element of the General Plan. Some of these requirements are triggered by updates to the Housing Element. Check to see if there are any new requirements of this nature. Note that the requirement is linked to the new Housing Element's adoption date, not the date the update process begins.
Because the LHMP is incorporated into the Safety Element, any amendments or revisions to the Safety Element triggered by the Housing Element update may be made directly in the LHMP. Requirements triggered by the Housing Element are unlikely to require a full rewrite of the LHMP, but the process should fully involve the Planning Committee and include appropriate community engagement.
Adopt the updated LHMP and incorporate it into the Safety Element. If necessary, amend the Safety Element to ensure the two documents are consistent (review the "Incorporate New Requirements Into the Safety Element, and Ensure that the LHMP is Consistent with the Safety Element" subsection above).
The Aliso Viejo Municipal Code
Aliso Viejo's Municipal Code contains a set of standards that guide land uses and development in the community. These standards include where different types of buildings and land use activities may be located, how these structures must be built, and how they must be operated or maintained.
The Municipal Code may include requirements that structures (particularly new structures or those undergoing substantial renovations) incorporate hazard- resistant features, be located outside the most hazard-prone areas, or take other steps to reduce hazard vulnerability.
All communities in California are required to adopt the minimum state Building Standard Code (BSC), which includes some hazard mitigation requirements for new or significantly renovated structures. The BSC is generally updated every three years, with suppl emental code updates halfway into each update cycle. Title 13, "Buildings and Construction," of Aliso Viejo's Municipal 240
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
E-12
Code contains building regulations and incorporates the BSC. Other sections of the Code adopt additional standards as desired by the City that adapts the BSC to Aliso Viejo's local context.
As a participant in the National Flood Insurance Program (NFIP), Aliso Viejo is required to incorporate Floodplain Management Requirements in its Zoning Code, which is located in Chapter
7.50 – Floodplain Management Overlay District . These regulations establish standards for developing and operating facilities within mapped flood- prone areas. Other sections of the Aliso Viejo Municipal Code may include additional standards related to hazard mitigation activities.
With the exception of the Floodplain Management Regulations and the minimum standards in the BSC, Aliso Viejo is not required to incorporate hazard-related requirements in the Municipal Code.
However, the Municipal Code is an effective tool for implementing hazard mitigation measures related to the siting, construction, and operation of new buildings and other structures. Substantial updates to the Municipal Code, including the Buildings and Construction and Zoning Code sections, should be done in a way that is consistent with the LHMP.
I
NCLUDE HAZARD-RELATED REQUIREMENTS IN APPLICABLE SECTIONS OF THE ALISO VIEJO CODE OF
ORDINANCES
If the BSC is being updated, evaluate the hazard-related requirements of all sections in the new BSC. Identify any areas where it may be feasible to add or revise standards to help reduce the threat from hazard events. Ensure that these standards are consistent with the LHMP. Consider whether standards should be applied to all structures, to specific types of structures, or to structures in a limited area (such as a flood plain).
If the Zoning Code is being updated, ensure that all requirements do not expose community members or community assets to an excessive risk of harm. Where feasible, use the requirements to strengthen community resiliency to hazard events. Ensure that these standards are consistent with the LHMP. Consider possible standards such as overlay zones that strengthen zoning requirements in hazard-prone areas, landscaping and grading requirements that buffer development from hazards, siting, and design standards that make structures more resilient, and other strategies as appropriate. 241

ATTACHMENT 3: SAMPLE AGENDA AND TOPICS FOR THE
HAZARD MITIGATION PLANNING COMMITTEE
This attachment includes a sample agenda and discussion topics for the annual meeting of the Planning Committee. Meetings do not have to follow this order or structure, but the items included in this attachment should be addressed as part of the annual meeting. During the update process for the LHMP, it is likely that the Planning Committee will meet more frequently. The meetings of the Planning Committee during the update process will involve different discussion topics.
Item 1: Recent Hazard Events
1.1. What hazard events have occurred this past year in Aliso Viejo or nearby in a way that affected the community?
• Identify events that caused loss of life or significant injury to Aliso Viejo community members, significant property damage in Aliso Viejo , or widespread disruption to Aliso Viejo.
• More minor events should also be identified if there is a need for a community response to mitigate against future events.
1.2. What are the basic facts and details behind such hazard events? • Consider the size and location of the affected area, any measurements of severity, any injuries and deaths, the cost of any damage, the number of people displaced or otherwise impacted, and other relevant summary information.
• Ensure that these facts and details are clearly recorded for future plan updates, including using the Disaster Information Table ( Attachment 1).
Items 2: Mitigation Action Activities
2.1. What mitigation actions have been fully implemented? Are they working as expected, or do they need to be revised?
2.2. What mitigation actions have been started since the last Planning Committee meeting? Is implementation proceeding as expected, or are there any barriers or delays? If there are barriers or delays, how can they be removed?
2.3. What mitigation actions are scheduled to begin implementation in the next year ? Are there any factors that could delay implementation or weaken their effectiveness? How can these factors be addressed?
2.4. What resources are needed to support planned, in-process, or ongoing mitigation actions? Does the City have access to these resources? If not, how can the City obtain access to these resources?
Item 3: Information Sharing
3.1. Is the City communicating with all appropriate local jurisdictions, including neighboring communities, Orange County, and special districts? This should include information on specific hazard situations, mitigation actions, and other relevant information. 244
City of Aliso Viejo 2024 Local Hazard Mitigation Plan
E-16
3.2. Is the City communicating with the appropriate state and federal agencies? Is the City receiving information about new regulations, best practices, and data related to hazard mitigation activities?
3.3. Are there opportunities for the City to improve coordination with local, state, and federal jurisdictions and agencies?
Item 4: Budgetary Planning
4.1. What financial resources are necessary to support the implementation of planned, in - process, and/or ongoing mitigation actions ? Is there sufficient funding for all measures planned for the next year, including in- process and ongoing items? If sufficient funding is unavailable, how can the City obtain these funds?
4.2. If it is not feasible for the City to support all planned, in-process, or ongoing mitigation actions, which ones should be prioritized?
4.3. Are there hazard-related activities not included in the LHMP that should be budgeted for? Can the City obtain the necessary funding for these activities? Item 5: Strategic Planning
5.1. Which grants are available for hazard mitigation activities, and which activities are best positioned to secure funding?
5.2. How should the agencies and other organizations represented on the Planning Committee coordinate to maximize the chances of receiving funding?
5.3. Are there any scheduled or anticipated updates to other City documents that could relate to hazard mitigation activities? How can the Planning Committee share information with staff and any technical consultants responsible for these updates and ensure that the updates will enhance community resilience?
5.4. What capital projects are scheduled or anticipated? Are these capital projects being designed and built to be resistant to hazard events? Are there opportunities for these projects to support hazard mitigation activities?
5.5. How can Planning Committee members coordinate efforts with those responsible for capital projects to take advantage of economies of scale that will make implemention easier?
5.6. Has it been 3.5 years since the adoption of the LHMP? If so, lay out a timeline for plan update activities, including additional meetings of the Planning Committee. Identify if a technical consultant is needed and begin the contracting process.
5.7. Are there any other opportunities for Planning Committee members and the organizations they represent to coordinate efforts?
Items 6: New Business
6.1. Are there any other items related to the Planning Committee's mission?

Dear Sarah Limones:
The Federal Emergency Management Agency (FEMA) has completed its review of the City of Aliso Viejo Local Hazard Mitigation Plan 2024 and has determined that this plan is eligible for final approval pending its adoption by the City of Aliso Viejo.
Formal adoption documentation must be submitted to FEMA Region 9 within one calendar year of the date of this letter, or the entire plan must be updated and resubmitted for review. FEMA will approve the plan upon receipt of the documentation of formal adoption.
If you have any questions regarding the planning or review processes, please contact the FEMA Region 9 Hazard Mitigation Planning Team at [email protected].
Sincerely,
Alison Kearns

AGENDA ITEM
DATE: June 19, 2024
TO: Mayor and City Council
FROM: Mitzi Ortiz, Acting City Manager
SUBJECT: BIENNIAL REVIEW OF THE CITY’S CONFLICT OF INTEREST CODE Recommended Action:
Direct staff to review the City’s Conflict of Interest Code for updates and submit its findings to Council by October 1, 2024.
Fiscal Impact:
None.
Background:
Pursuant to the Political Reform Act, the City adopted a Conflict of Interest Code which consists of standard provisions contained in Section 18730 of Title 2 of the California Code of Regulations, as amended. The Code also designates City officials, officers, employees, and consultants who make or participate in making governmental decisions which may affect their financial interests, who must disclose those interests in certain financial disclosure statements, and who must disqualify themselves from making or participating in the making of governmental decisions affecting those interests.
The Political Reform Act requires the City Council, as the code reviewing body, to direct staff to review the Code by July 1 of each even-numbered year. Staff must then submit a biennial notice to Council by October 1 indicating whether amendments are needed. If so, the amended Code will be presented to Council for approval by resolution.
Discussion:
The City’s first Conflict of Interest Code was adopted in 2001. The Code has subsequently been reviewed biennially with the last amendment approved in 2022. With City Council direction, staff will begin a thorough review of the Code with assistance from the City Attorney’s office. Staff will submit its findings to the Council for consideration by October 1, 2024.

AGENDA ITEM
DATE: June 19, 2024
TO: Mayor and City Council
FROM: Ann Eifert, Director of Financial Services
SUBJECT: PROPOSED ANNUAL BUDGET FOR FISCAL YEAR 2024-25 Recommended Actions:
1. Adopt a Resolution adopting the Annual Budget for Fiscal 2024-25; and
2. Adopt a Resolution approving City Salary Schedules.
Fiscal Impact:
The proposed fiscal year (FY) 2024-25 budget includes appropriations for programs and projects necessary to provide essential services to the community. General Fund revenues are estimated to total $26.7 million. Staff is proposing a prudent General Fund expenditure budget with budget reductions across all departments. The total expenditure budget is approximately $27.1 million and includes all operating costs, capital improvement expenditures, debt service, and interfund transfers.
A General Fund operating budget surplus is estimated at $0.1 million with General Fund reserves anticipated to fund $0.5 million in capital improvement, resulting in a net decrease to fund balance of $0.4 million. The estimated year-end General Fund balance will decrease by approximately 1% to $34.3 million.
In addition to the General Fund, the City uses “Special Revenue Funds” to fund various City expenditures. Special Revenue Funds are typically restricted funds, such as Gas Tax, SB 1, Measure M, Federal Grants, and Other Grants. These funds can only be used for specific purposes. Revenue and appropriations for all Special Revenue Funds for FY 2024-25 are approximately $9.9 million and $9.1 million, respectively.
At the end of FY 2024-25 operations, the estimated fund balance for all City funds will be approximately $40.0 million.
