A social threat analysis examines how hazard events are likely to impact different demographic populations in Pasadena 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 often 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. Figure 5-2 below demonstrates the total number of people with a disability by census tract in the City of Pasadena.
• Income levels: Lower-income households are less likely to have the financial resources to implement mitigation activities on their residences. They may also struggle with having the necessary time to find and access educational resources discussing hazard mitigation strategies. Furthermore, lower-income households are less likely to be able to move to safer areas that are less at risk of being impacted by a hazard.
• 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 5-2 shows the number of people in Pasadena who meet at least one of the criteria for threatened or vulnerable populations. For more detailed demographic information, please refer to Section 3. Figures 5-3 – 5-5 provide further information of vulnerable populations in the City of Pasadena.

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 is not readily available, there is no definitive way to determine the amount of these persons in areas of elevated risk, so this assessment will discuss how these other threatened groups may be affected on a general level.

5.2.1 Data Limitations and Notes on Vulnerability Figures The planning team used City provided demographic data to determine the percentage of residents with a disability. This 2017 data (the latest available) showed that 10.2 % (percent) of the population had a disability. The team also considered using the 2020-23 U.S. census data for this purpose. The census data listed 5.3% (percent) of the population with a disability. Census data only provides information on disabilities for people under 65. The planning team selected the 2017 data point as being more inclusive. Both data sets used the Six Standard Questions Census criteria for determining a disability.
5.3 Identification of Critical Facilities and Assets
The location and operations of high-risk facilities such as critical infrastructures and key assets in or near the City are a significant concern with respect to a disaster. The planning team used FEMA's “Public Assistance Guide” (FEMA 322) 22 that defines critical facilities like data centers, utility plants, or highly hazardous materials facilities.
They also used the FEMA Hazard Mitigation Handbook, which describes three (3) categories of facilities for analysis to revise this list: critical facilities for City operations; high potential loss facilities and facilities with hazardous materials; and critical infrastructure such as police/fire stations, streets and bridges, reservoirs, and pump stations.
5.4 Other Assets
In addition to the City’s designated inventory of CFs/FOC and vulnerable populations, hazard events could threaten other important assets to Pasadena. 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.
5.5 Risk Assessment and Potential Loss
The risk assessment and potential losses for physical damage for City facilities are listed in the tables below. Because the City provides a critical lifeline infrastructure support system, potential losses beyond physical damage must be considered. Loss of potable water service due to non-destructive events results in community hardship, economic loss, and reputational damage. Computing potential losses from these risks is beyond the scope of this LHMP and must be considered in the context of the impact on the entire City.

5.6 Analysis of Potential Losses by Hazard
Dam Failure
Physical Threat
Various factors, such as the amount of water released, the distance between the dam failure site, and the topography of the surrounding land, will influence the extent to which physical assets in Pasadena are threatened. Devils Gate Dam and Eaton Wash Dam have large storage capacities that could cause localized inundation in Pasadena if the reservoir waters are released due to a dam breach. Table 5-3 identifies the physical assets in Pasadena that are threatened by the potential failure of Devils Gate and Eaton Wash Dam. Based on this analysis, dam inundation would affect 4 CFs and 2 FOCs within the City, with the potential to cause approximately $437 million in damage, based on available information. Figure 5-6 shows the location of the identified CFs and FOCs within these dam inundation zones.

Dam failure hazards in the City would impact various downstream properties and the residents that live there. Table 5-4 identifies these potential dam failure impacts caused by the Devils Gate and Eaton Wash Dam. Failure of the two (2) dams would affect almost 10% of the population and inundate 5% of the acreage in the City of Pasadena.

Other Threats
Dam failures are often triggered by other events (e.g., seismic shaking, intense rainstorms, etc.). There would most likely be service disruptions in Pasadena if this type of event occurred. Floodwater could quickly inundate the city, disrupting utilities such as water, power, and other services (communications or transportation infrastructure).
Residents may find street lighting and traffic signals are temporarily disabled. Debris carried by the rapid inundation may result in injury of death, destroyed structures and facilities and damage to transportation systems.
Changes in Population Patterns and Land Use and Development Population in the inundation zone may choose to move out of the City or out of the inundation area if the impacts of dam failure are great enough. Those renting homes within the City (61% of households within the City) have little control over the rebuilding process of a home that has been affected by inundation and, therefore, may be forced to move out of the inundation area or out of the City.
Dam failure is unlikely to affect land use and development because the development review process will take steps to mitigate or minimize flood-related impacts. Areas inundated within the City would not be significantly altered, requiring changes in land use and development patterns
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
172
Drought
Physical Threat
Since the primary threat from drought is reduced water supply and availability, there are no foreseeable threats to any of the City’s physical assets. It is possible that any water delivery infrastructure not used or used less than usual may fall into some degree of disrepair if maintenance is deferred. Lower water pressures may cause some aged water pipes to release rust particles into the water supply. Amenities within facilities, like water features and landscaping, could be affected by reduced watering. If dead or dying vegetation becomes a nuisance, the City may have to replace or retrofit locations affected.
Social Threat
Droughts are unlikely to cause serious social threats to households in Pasadena, though residents and business owners in the City may experience financial impacts associated with water conservation efforts. Those with less access to financial resources, such as low-income households or seniors, could be harder hit if higher water rates or additional fees are imposed during a severe drought event.
Other Threats
A typical drought is not anticipated to lead to any outages in service in Pasadena.
However, an exceptional drought may lead to restricted water use for residents or businesses in the City. Trees that are not adequately adapted to lower irrigation levels could perish, altering the City’s aesthetic appearance and long-term air quality. Any open spaces with extensive lawns may start to die, turning brown, which could discourage residents from using these parks and open spaces. In addition, long-term drought conditions can change and reduce soil’s ability to absorb water. When this occurs, water runoff from these areas may increase, which could cause downstream flooding and erosion in some areas.
Changes in Population Patterns and Land Use and Development Droughts occur periodically (primarily during the Summer/Fall months) and generally do not affect populations to the degree that they would need to migrate in and out of the City. The anticipated population growth in Pasadena is unlikely to have any significant effect on population growth.
It is unlikely that drought will affect land use and development because the development review process will take steps to mitigate or minimize the impacts and vulnerability of drought in Pasadena.

Earthquake
Physical Threat
Seismic Shaking
Many physical assets in the City are estimated to experience the same seismic shaking intensity, ranging from 85 to 95% (shaking intensity in relation to the earth’s gravity).
Therefore, all facilities could be damaged during a significant seismic event, which would 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 $252 million.
Underground physical assets, like pipelines or utilities, could be damaged if seismic shaking were strong enough to cause a rupture. In such a scenario, natural gas and water delivery service to Pasadena homes and businesses would be incapacitated until repairs are completed. Table 5-5 displays these potential scenarios and losses that could incur should shaking reach the described threshold. Figure 5-7 displays the CFs and FOCs within the City’s seismic shaking potential hazard zones.

** Based on the City of Pasadena insured replacement values Figure 5-7: Earthquake Threat Map with City infrastructure Subsidence
Subsidence can influence both the built and natural environment. Because water lines are gravity-driven, a change in elevation due to subsidence could make the system more inefficient. Structures built in areas that experience subsidence may require retrofitting or relocation. Subsidence could also irreversibly decrease an aquifer’s capacity to store water. Table 5-6 shows 107 CF, and 50 FOC could be affected by land subsidence in the City, resulting in a loss of almost $1,261,099,373. Figure 5-8 displays the CFs and FOC within the City’s land subsidence hazard zones.

Social Threat
The risk of a seismic event is a danger to all groups in Pasadena though some are more threatened than others.
Seismic Shaking
Seniors, pregnant women, and persons with disabilities are more threatened by seismic shaking since they may have limited mobility and may be unable to reach shelter in time. Even if these groups reach shelter in time, they may find themselves trapped if furniture or building components have fallen around them. Renters and low-income people are also more threatened by seismic shaking since these groups may live in homes that are not properly retrofitted to survive the stresses of a seismic event. These groups may not be able to absorb the costs associated with repairing their homes or looking for new housing should their existing one be too damaged for occupancy. Table 5-7 displays the threatened populations in Pasadena associated the seismic shaking scenarios.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
176
Subsidence
While subsidence can cause significant issues with physical infrastructure, many of the social impacts can be related to where people live and work. Subsidence can impact the safety of homes and businesses. Buildings could gradually sink due to subsidence, causing minor issues such as cracks or misalignments of doors and windows or more costly problems such as sinkholes. These issues could impact residents living in older homes, which may not have been built with foundations reinforced with steel. Because insurance companies may not cover damages caused by subsidence or other geologic hazards, lower-income households may find it financially difficult to cope with subsidence. Table 4-26 displays the populations characteristics of those in Pasadena threatened by land subsidence. Approximately 80% of the City’s residents live in an area with land subsidence and share similarities with the demographics of the entire City.
Other Threats
Seismic Shaking
With early earthquake warning systems becoming operational, it can be expected that utilities will take advantage of these advance warnings to shut off gas, water, and power transmission to control any potential leaks following the seismic shaking. Authorities may have enough time to halt the use of infrastructure or move workers to safe locations away from hazardous conditions. Workers could cease their activity and take shelter until they can be safely evacuated. Therefore, all services could be non- operational during the shaking event and remain inactive until authorities are confident that it is safe to reactivate utilities and return employees to their workplaces. The length of this time would vary depending on the magnitude of the event. A significant earthquake would likely put utilities out of commission and halt any employment activity in the City for a few hours or several days. The City and the region would experience reduced economic activity during the outage period, which would not be felt for weeks, months, or years later. Structures such as telephone poles or power transmission towers felled by the shaking could block roadways and prevent emergency response teams from reaching victims or evacuees who need assistance.
Subsidence
If subsidence occurred in Pasadena, causing impacts to homes and businesses, the City would need to identify the locations of impact and potential triggering event.
Damage to roads, rail lines, and underground pipes (water, wastewater, and natural gas) is likely to be impacted during a subsidence event. As a result, the areas impacted CITY OF PASADENA 2025 Local Hazard Mitigation Plan
177
by these effects could experience a loss of City services and potential congestion if roadways are impacted.
Changes in Population Patterns and Land Use and Development Seismic Shaking
It is not anticipated that population patterns will change 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 may be impacted more severely than newer structures in the City.
Subsidence
Although subsidence is being monitored throughout the City, its effects happen very slowly, and the impacts cause minor damage to structures that can be repaired.
Because of this, subsidence is unlikely to cause changes in population patterns as well as land use and development. The City’s development review process will identify steps to mitigate or prevent future subsidence.
Extreme Weather (Severe Winds, Extreme Heat, Severe Rainstorms) Physical Threat
Severe Winds
Intense winds likely present the greatest threat to physical structures, particularly from trees or branches that fall on buildings/vehicles, causing 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. Often utility poles and trees suffer impacts during high wind events if they occur after a significant rain event. During these events, saturated soils around the base of the tree/pole may be unable to hold up to the strains placed on it by strong winds causing it to fall over.
Trees, tree branches, and other objects have the potential to fall on powerlines and other electrical infrastructure during a severe windstorm, causing power outages throughout the City. Another physical threat of severe wind is wildfire impacts during the summer months.
Extreme Heat
Extremely high temperatures can cause roads to deform and buckle as the pavement expands in the heat, especially in areas that have not been maintained well. Power lines and other electrical grid components become less effective in higher temperatures and CITY OF PASADENA 2025 Local Hazard Mitigation Plan
178
may be damaged due to stress during extreme heat events. Urban heat islands occur when natural land cover is replaced with concentrations of pavement, buildings, or other surfaces that absorb and retain heat. Buildings with dark pavement will absorb more heat than surfaces with vegetation or lighter materials that are better at reflecting the sun’s energy. This urban heat island effect is strongest during the summer when solar radiation is strongest.
Severe Rainstorms
Physical threats associated with severe rainstorms are similar in nature to those identified in the Flood discussion below.
Social Threat
Severe Wind
Severe wind events can harm people throughout Pasadena but have a greater effect on the safety of people experiencing homelessness and those working outdoors.
Populations that work outside or have respiratory illnesses may be impacted by severe wind events as they can generate dust and other contaminants that can affect the health of residents and workers. Lower-income residents, who may not have the financial resources to purchase homes (or are renting homes) that are not built or retrofitted to withstand powerful winds, could also have difficulty recovering from wind events.
Extreme Heat
Whereas a heat event can be relatively harmless for those with a reliable means of staying hydrated and cool, the event can be deadly for others. Young children, the elderly, or people suffering from serious medical conditions are physiologically more vulnerable to heatstroke. Some senior citizens also take medicines that can make it harder for their bodies to maintain a safe internal temperature, creating an additional threat from extreme heat events. Young children may not be aware of the signs of dehydration or ways of protecting themselves from heatstroke.
People living in homelessness are at a high risk of health complications during heat waves, especially if they are unsheltered. According to Pasadena homelessness count, in 2025, there were approximately 556 individuals experiencing homelessness in the City, with 57% percent unsheltered. This population is very vulnerable to heatstroke during a heatwave, especially if they cannot reach a cooling center.
Sudden spikes in heat can catch people by surprise. Stores can rapidly sell out of fans, air-conditioning units, or drinking water during a heatwave. Many lower-income households live in older, poorly insulated, and energy-inefficient housing and cannot CITY OF PASADENA 2025 Local Hazard Mitigation Plan
179
afford to run their air conditioning, which can be further compounded by the threat of power outages due to heat/rolling blackouts. During these events, extreme heat impacts may affect larger portions of the City and populations that would not be viewed as vulnerable under normal circumstances.
Sever Rainstorm
Social threats associated with sever rainstorms are similar in nature to those identified in the Flood discussion below. The following populations are most vulnerable to severe weather:
• Households with financial instability.
• People that spend an extended amount of time outdoors. • People with existing health conditions or limited mobility. • People with language barriers and citizenship uncertainty. • People living in mobile homes.
• Overcrowded households.
Other Threats
Severe Wind
Southern California and the City all suffer from seasonal Santa Ana Winds and will for the near future. Extreme wind events can worsen other risks, such as wildfires.
Extreme Heat
Extreme Heat for any length of time can also affect other hazards and risks within the City. For example, it can create a spike in electricity demand leading to power loss/failure, food insecurities, and a rise in vector-borne disease transmission. Coupled with extreme wind, it can cause or spread urban fires and jeopardize additional neighborhoods/ communities.
Severe Rainstorm
Other threats associated with sever rainstorms are similar in nature to those identified in the Flood discussion below. Severe rain can lead to debris flows in wildfire affected areas of the City and cause significant property damage to areas of the City.
Changes in Population Patterns and Land Use and Development Severe Wind
Severe winds 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.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
180
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 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.
Extreme Heat
Based on the recent update to TOP 2050 (General Plan), it is not anticipated that population patterns will change over the next 20 years. There could be minor changes in population patterns due to extreme heat if people cannot continue to live in older structures with limited insulation and older cooling units.
It is unlikely that extreme heat will affect land use and development because the development review process will take steps to mitigate or minimize impacts from extreme heat. While it is unlikely that extreme heat will affect land use and development, it is possible that additional investment in older parts of the City will occur to modify structures to handle these conditions.
Severe Rainstorm
Severe rainstorms occur periodically (primarily during the winter months) and generally do not affect populations to the degree that they would need to migrate in and out of the City. However, in rare circumstances, there may be the need to evacuate households for a short period of time until the flooding recedes.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
181
Flooding
Physical Threat
No portions of the City are located within the 100-year flood zone (1.0% Annual Chance of Flooding) and the 500-year flood zone (0.2% Annual Chance of Flooding). Although not a “priority” hazard, it is worth to note aspects of the Flood hazard. Flooding in the City of Pasadena is generally related to urban flooding, not riverine flooding. Although the City has gone through several flood events in which properties have experienced repetitive loss, there are no properties that fall under the NFIP definition of Repetitive Loss Properties. The City of Pasadena has two (2) repetitive loss properties, both residential properties. One property has two (2) claims and is located on the southern boundary of Eaton Canyon Park; the other property has three (3) claims and is located just west of the Rose Bowl.
Any physical assets within these mapped boundaries can potentially be inundated if enough precipitation falls, exceeding the storm drain infrastructure design capacity in these areas. Electronic or mechanical equipment on the ground could be impacted causing it to fail. Table 5-8 identifies that one (1) physical asset within the City is located in the 100-year flood zone. Table 5-8 - 5-9 identifies 3 physical assets within the City located in the 500- year flood zone. In total, these facilities are valued at over $12 million. Figure 5-9 depicts the locations of CFs and FOCs located in FEMA- designated flood zones, which include the 100-Year Flood Hazard (blue), 500-Year Flood Hazard (orange), and Areas with Reduced Flood Risk Due to Levee (yellow).

CITY OF PASADENA 2025 Local Hazard Mitigation Plan
183
Social Threat
Floodwaters in both the 100-year zone and the 500-year zone are anticipated to rise to a depth of no more than one foot above the base flood elevation. 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, people with disabilities, and low-income people are also likely to be impacted during these events. Figure 5-9 shows the proportion of Pasadena’s vulnerable populations that face a greater threat from a flood event. Based on the information in Table 5-10, the median household income in both the 100-year and 500-year flood zones is higher than the citywide average.
People experiencing homelessness who are outside during flood conditions may experience property damage or be unable to access shelter. Though floodwaters in Pasadena are not expected to exceed a depth of one foot in many areas, six inches (6 in.) of floodwater may render any makeshift structures uninhabitable during a flood event. Possessions such as sleeping bags or electronic devices may be damaged or swept away by these floodwaters.
Additionally, the 2022 Vulnerability Assessment has identified the following populations as flood-threatened populations:
• Households with financial instability.
• People that spend an extended amount of time outdoors. • People with existing health conditions or limited mobility. • People with language barriers and citizenship uncertainty. • People living in mobile homes.
• Overcrowded households.
Other Threats
Flooding may temporarily stop any type of transportation in the City. Debris from floodwaters can block roadways, hinder vehicle access, and potentially affect emergency response services. One foot of rushing water is enough to carry small vehicles, depending on the velocity. 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.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
184
Changes in Population Patterns and Land Use and Development It is unlikely that flooding will affect land use and development patterns in affected areas because the median income in impacted areas is higher than the City average.
Additionally, the development review process ensures flood related impacts are mitigated or minimized.

Public Health Incidents: Pandemics, Epidemics
Physical Threat
Public Health events will not harm buildings or infrastructure within the City. However, the regional or global nature of public health incidents might incur indirect costs through personnel death and disease, absenteeism, and reduced efficiency. Public health incidents will likely threaten the city’s administrative and facilities operations, whereas automated services and infrastructure itself will not be significantly impacted.
Social Threat
Pandemics can overwhelm healthcare systems, creating shortages of medical supplies and causing significant morbidity and mortality. In addition to the physical health impacts such as respiratory distress, organ failure, and long-term complications for survivors, healthcare workers face an increased risk due to their exposure to infected individuals.
Beyond these immediate health impacts, pandemics disrupt daily life, leading to school closures, business interruptions, and economic downturns. The psychological toll on individuals and communities can be profound, with increased levels of anxiety, depression, and stress. These factors contribute to changes in population, influencing migration patterns, birth rates, and mortality rates, thereby altering the demographic landscape.
Fire
Physical Threat
Wildland Fire
The California Department of Forestry and Fire Protection has mapped Very High Fire Hazard Severity Zones (VHFHSZ) within the City’s Local Responsibility Area (LRA). 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 5-10 identifies these zones and the City’s CFs and FOCs within the area. All structures within this fire zone are at an elevated risk of wildfire impacts.
All structures located within this zone are at an elevated risk of wildfire impacts. Table 5- 11 identifies 4 CFs and 7 FOC within the wildfire hazard zone, resulting in a potential loss of approximately $145 million based on available replacement values. Additional losses associated with the loss of homes and schools in these areas could also occur resulting in a significant amount of cost.
While these areas have a high degree of vulnerability to wildfire, other areas of the City may also be susceptible to ember cast. These areas, typically referred to as the WUI CITY OF PASADENA 2025 Local Hazard Mitigation Plan
186
(Wildland Urban Interface), are vulnerable if the right conditions exist. Typically, the WUI is impacted if adequate fuels are combined with dry conditions and strong winds.
Sometimes, the ignition of a wildfire may occur if power lines around overgrown trees cause a spark and catch the tree on fire.

Urban Fire
Structures and physical assets in Pasadena 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, or may not meet current code requirements and regulations. While all structures can be impacted by urban fire, older structures may have increased vulnerability to this hazard. Power lines located around overgrown trees, where the tree crown envelops part or all the power lines, are also at risk of catching fire. When the wires overheat, they may ignite a fire in the tree, spread back to the power lines themselves, and burn the power line infrastructure.
Underground utilities, like water delivery systems, residential electrical systems, or natural gas pipelines, are not threatened by the occurrence of fire since any urban fires that emerge in Pasadena are likely to occur on the surface.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan

Figure 5-11: Critical Facilities and Facilities of Concern (Previous adopted fire hazard map)
Social Threat
A fire hazard most immediately threatens seniors and people with disabilities. These groups may have limited mobility and reduced environmental awareness. For example, a senior who lives alone may not be aware that a fire has been ignited in their house until the room begins to fill with smoke or even flashover, at which point escape may be more difficult or impossible. Therefore, a fire that starts in or spreads to any senior residences in Pasadena could be highly threatening to those populations. People with disabilities may require special mobility devices or caregiver assistance to go outside, which may not be readily available if a fire occurs. Other groups with increased threat levels include lower- income people and renters. These people may live in substandard housing with outdated materials known to be flammable. Renters and lower-income persons may also live in housing units with improperly designed or maintained electrical
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
189
or heating systems that could lead to a fire. Additionally, these groups may not possess enough financial resources to rebuild their homes or search for new homes after a fire occurs.
Other Threats
Fires can consume power lines and force utility operators to shut off electrical and gas transmission activity, leading to utility outages in Pasadena homes and businesses. Any streets surrounded by blazes or blocked by burning debris would hinder transportation, prevent people from evacuating, and block emergency response crews from reaching the source of the fire. Anyone living at the end of a cul-de-sac faces an elevated threat of being trapped if the fire occurs or spreads in a way that blocks evacuation. Fires that destroy trees or vegetation (especially within parks and open space areas) could limit or prevent the use of these areas, affecting future recreational opportunities for residents.
Outreach to residents and businesses to help them understand and prepare for these future events will become an important aspect of the City’s overall hazard mitigation strategy.
Changes in Population Patterns and Land Use and Development If a large urban fire were to occur, it is feasible that changes in population patterns could occur. Land use and development patterns could change if a large urban fire were to occur that impacted older parts of the City. After that type of event, the City would rely on a redevelopment process to determine how best to rebuild.

Human-Caused Hazards
Physical Threat
Air Quality
Air pollution exposure is associated with oxidative stress and inflammation in human cells, which may lay a foundation for chronic diseases and cancer. In 2013, the International Agency for Research on Cancer of the World Health Organization (WHO) classified air pollution as a human carcinogen. Short-term exposure to higher levels of outdoor air pollution is associated with reduced lung function, asthma, cardiac problems, emergency department visits, and hospital admissions.
Air pollution and climate change affect each other through complex interactions in the atmosphere. Air pollution is intricately linked with climate change because both problems come largely from the same sources, such as emissions from burning fossil fuels. Both are threats to people’s health and the environment worldwide.
Civil Disturbance
Civil disturbance, depending on the cause and effect, could have a considerable impact on the population, built environment, lifeline infrastructure, economy, and the environment. Downtown Los Angeles is a frequent site of demonstrations due to its high profile and presence of government buildings. It is conceivable that a demonstration could turn to violence and begin spreading into neighboring communities. While the City does not have a history of riots, it also has a high profile and has several events which attract large crowds. This coupled with increased causes creating disharmony within society may provide opportunities for some individuals.
Cyber Attack
A significant cyber event could have considerable impact on the population, built environment, lifeline infrastructure, environment, and the economy. Most jurisdictions have several levels of security in place, dependent upon security levels of individuals and the geographical locations (onsite or remote). Many also have redundant dispatch centers with separate systems that can function if the primary center isn’t functioning.
Cyber-attacks can infiltrate many institutions including banking, medical, education, government, military, and communication and infrastructure systems. Most of the effective malicious cyber- activity has become web based. Recent trends indicate that hackers are targeting users to steal personal information and targeting computers to cause system failures. The duration of a cyber-attack is dependent on the complexity of the attack, how widespread it is, how quickly the attack is detected, and the resources available to aid in restoring the system. A cyber-attack could be geared toward one CITY OF PASADENA 2025 Local Hazard Mitigation Plan
191
organization, one type of infrastructure and/or a specific geographical area. The affected area could range from small to large scale. Cyber-attacks generated toward large corporations can negatively affect the economy. A 2014 report from the MacAfee Corporation stated that the annual global loss to the global economy is between $375B and $500B. Attacks geared toward critical infrastructure and hospitals can result in the loss of life and the loss of basic needs, such as power and water, to the public. Cyber- attacks can lead to the loss of operational capacity.
Hazardous Materials Release (Pipeline Failure, Oil Spill, Transportation Incident) Hazardous materials can cause damage to physical assets in Pasadena if they are released into the environment. Corrosive hazardous materials can damage the exteriors of buildings or structures. Flammable hazardous materials can be ignited and cause damage to nearby structures. Generally, sites closer to the origin of the release of hazardous materials are more at risk than those further away.
The total potential losses associated with these assets are over $59 million based on replacement costs.
Transportation incidents typically threaten infrastructure like roadways, bridges, and utilities that may be adjacent or co-located with these facilities. Depending on the nature of the event surrounding structures and uses may also be impacted; however, to what degree it is difficult to identify at this time. While many incidents within the City may be considered minor, if one were to occur at a key intersection or interchange, traffic, and commerce within the affected area could be impacted significantly for hours or days, depending on the severity of the incident.
Power Outage
Energy shortage/outages (disruptions) are considered a form of lifeline system failure and could have a significant impact on the population, built environment, infrastructure, and the economy. Disruptions can be the consequence of another hazard, or can be the primary hazard, absent of an outside trigger. Pasadena and Southern California as a whole have experienced population growth, coupled with changes to daily lifestyles and weather have contributed to a heavy demand for power over recent years.
There are two (2) factors to consider: 1) increased demand within the City; and 2) increased demand elsewhere. Because Pasadena is connected to the Southern Californian Edison (Edison) power grid, increases in other parts of the state could curtail the energy available to Pasadena. This vulnerability is compounded by the reality that our communities have become more reliant on power for gadgets and appliances to perform basic daily activities. This loss of power will not only be an inconvenience but CITY OF PASADENA 2025 Local Hazard Mitigation Plan
192
could become a life-threatening experience. Many citizens rely on power to operate medical machinery to survive (i.e., oxygen tanks, dialysis machines).
Climate change considerations indicate that as the weather conditions change, there could be an increase in energy needs. This could be from both the potential increase in heat and cold. These predicted increases will put ever greater strain on Pasadena’s energy supply.
Terrorism
There is no way to predict which of Pasadena’s facilities or assets may be impacted by an act of terrorism since the motivation behind the incident is often complex and not easily understood. Generally, these 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. The financial losses that may result from this type of incident would depend on the degree of destruction associated with the activity. If the incident involves the destruction of physical assets, the cost to the City or property owners in Pasadena could be significant.
Social Threat
Air Quality
Air pollution exposure is associated with oxidative stress and inflammation in human cells, which may lay a foundation for chronic diseases and cancer. In 2013, the International Agency for Research on Cancer of the World Health Organization (WHO) classified air pollution as a human carcinogen. Many studies have established that short-term exposure to higher levels of outdoor air pollution is associated with reduced lung function, asthma, cardiac problems, emergency department visits, and hospital admissions. Mortality rates related to air pollution are also a concern. Exposure to the air pollutant PM2.5 is associated with an increased risk of death. Public health concerns related to high air pollution exposures include cancer, cardiovascular disease, respiratory diseases, diabetes mellitus, obesity, and reproductive, neurological, and immune system disorders.
Civil Disturbance
Since civil disturbance events can occur anywhere in the City, all groups are potentially threatened by the impacts of these incidents; however, the extent of the threat would be much greater to businesses. For example, in May of 2020, the George Floyd protest turned into civil disturbance and impacted hundreds of businesses in Southern California. Additionally, there have been isolated incidents of individuals ransacking businesses around the Country.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
193
Cyber Security Incident
Cities like Pasadena are an attractive target for criminals and cyber threat actors to exploit vulnerable systems to steal critical infrastructure data and proprietary information, conduct ransomware operations, or launch destructive cyberattacks.
Successful cyberattacks against cities could lead to disruption of infrastructure services, significant financial losses, exposure of citizens’ private data, erosion of citizens’ trust in the smart systems themselves, and physical impacts to infrastructure that could cause physical harm or loss of life.
Hazardous Materials Release (Pipeline Failure, Transportation Accidents, Oil Spills) 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, sewer mains, and transportation incidents that produce hazardous material spills. Table 4-14 shows the city’s vulnerable populations living within 500 feet of a hazardous materials storage/waste site. The median household income in these locations is almost $25,000 less than the rest of the city. This suggests that lower-income populations may be living near locations that store or use hazardous materials. Pasadena residents living next to major transportation infrastructure such as highways or major roadways also face a greater risk of being affected by hazardous materials release if vehicles transporting these materials accidentally release their contents into the environment.
Groups such as the elderly, low-income, and 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 relocate to a home farther from the potential sources of hazardous materials.
Residents and businesses located near major transportation infrastructure may be at greater risk of impact from these types of incidents. For residents that rely on the transportation network to get to work, any closures or impacts to that network could have a negative impact on their daily lives and well-being. At the same time, businesses could be impacted if employees and customers are unable to reach their place of business due to an incident. While many incidents would be short-term, reducing impacts to the community, if a significant issue were to occur, the impact could be longer, which could have economic impacts for both residents and businesses.
Power Outage
Power outages most immediately threaten seniors, people with disabilities, and those with home medical equipment. These groups often face the greatest threat during a power outage, during extreme heat.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
194
Terrorism
Since mass casualty incidents/acts of terrorism could occur anywhere in Pasadena, 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 buildings, financial institutions 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 hospitals than other subpopulations in the city. If an incident occurs at the hospital or within the community (overwhelming hospital 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 at Pasadena City Hall or bank locations in the City can be expected to be more of a threat to these groups. Seniors and people 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.
Changes in Population Patterns and Land Use and 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.
It is not anticipated that population patterns will change over the next 20 years. A change in population pattern would only occur if a hazardous materials release was severe enough to require people to move for a prolonged period of time due to soil contamination.
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.

SECTION 6: MITIGATION STRATEGY
Federal regulations require local mitigation plans to identify goals for reducing long-term vulnerabilities to the identified hazards in the planning area (Section 201.6(c)(3)(i)).
A hazard mitigation plan’s primary focus is the mitigation strategy. It represents the efforts selected by the City to reduce or prevent losses resulting from the hazards identified in the risk assessment. The strategy includes mitigation actions and projects to address the risk and vulnerabilities discovered in the risk assessment. The mitigation strategy consists of the following steps:
• Identify and profile hazards and risk within the City • Identify projects and activities that can prevent or mitigate damage and injury to the population and buildings
• Develop a mitigation strategy to implement the mitigation actions • Develop an action plan to prioritize, implement, and administer the mitigation actions
• Implement the LHMP mitigation action plan
A capability assessment was conducted of City authorities, policies, programs, and resources. Based upon this assessment and the hazard analysis and risk assessment, goals, and mitigation actions were developed. The planning team also developed a process to prioritize, implement, and administer the mitigation actions to reduce risk to existing facilities and new development
6.1 Hazard Mitigation Statement
The 2025 LHMP represents the City’s commitment to create a safer, more resilient community by taking actions to reduce risk and by committing resources to lessen the effects of hazards on the people and property of the city.
6.2 Hazard Mitigation Goals and Objectives
Mitigation goals are guidelines that represent what the community wants to accomplish through the mitigation plan. Goals are broad statements that represent a long-term, community-wide vision. The planning team reviewed the example goals and objectives from the previous LHMP and determined which goals best met the City’s objectives for mitigation. In addition to the overarching hazard mitigation goals, the City worked to CITY OF PASADENA 2025 Local Hazard Mitigation Plan
196
develop the strategies aligned with the CIP and other planning mechanisms that relate to hazard mitigation. Overall, mitigation priorities did not change for the City of Pasadena, the city continues to be very concerned about wildfire and earthquake risks.
The 2025 LHMP was revised to focus on the communities’ priorities as they relate to Climate Change, Wild/Urban Fire, and their commitment to involving vulnerable populations to the planning process. Table 6-1 lists the goals for the 2020 LHMP .
Table 6-1: Hazard Mitigation Goals
2025 Goals
Goal 1: Protect life and property, and reduce potential injuries from natural, technological, and human-caused hazards
Goal 2: Improve public understanding, support of, and need for hazard mitigation measures
Goal 3: Promote disaster resilience for the City’s natural, existing, and future built environment
Goal 4: Strengthen partnerships and collaboration to implement hazard mitigation activities
Goal 5: Enhance the City’s ability to effectively and immediately respond to disasters
6.3 Mitigation Actions/Projects and Implementation Strategy Mitigation actions are specific activities or projects that serve to meet the goals that the community has identified. Mitigation actions and projects are more specific than goals or objectives and often include a mechanism, such as an assigned timeframe, to measure the success and ensure the actions are accomplished. The planning team conducted a review of the mitigation actions and strategies from the State Hazard Mitigation Plan and from other cities’ planning efforts to develop new mitigation actions and projects to reduce the effects of hazards, with emphasis on new and existing buildings and infrastructure.
The requirements for prioritization of mitigation actions, as provided in the federal regulations implementing the Stafford Act as amended by DMA 2000, are described below.
Based on these criteria, the City prioritized potential mitigation projects and included them in the action plan discussed below in Table 6-3. The mitigation action plan CITY OF PASADENA 2025 Local Hazard Mitigation Plan
197
developed by the planning team includes the action items that the City intends to implement during the next five (5) years, assuming funding availability. The action plan includes the implementing department, an estimate of the timeline for implementation, and potential funding sources.
6.4 Previous Mitigation Actions/Projects Assessment
The 2018 HMP contained 62 mitigations actions. Many of the mitigation actions were completed or carried out to some degree or are considered ongoing. Some of the mitigation actions were duplicative, others were better categorized as emergency preparedness or recovery activities, and others were either not addressed during the time period or were not feasible to accomplish. Table 6-2 provides the status of mitigation actions from the 2018 HMP.

6.4.1 New Mitigation Actions
Mitigation actions are specific activities or projects that serve to meet the goals that the community has identified. Mitigation actions and projects are more specific than goals or objectives and often include a mechanism, such as an assigned time period, to measure the success and ensure the actions are accomplished. The planning team conducted a review of the mitigation actions and strategies from the 2018 HMP. With information from the risk assessment, capability assessment, and status of the actions implemented since the 2018 HMP, the planning team developed 32 new ongoing mitigation actions and projects to reduce the effects of hazards, with emphasis on new and existing buildings and infrastructure.
Table 6-3 lists the initial, potential mitigation actions developed by the planning team.
For each mitigation action, the following information is listed: type of mitigation project; hazard(s) addressed, type of development affected by action; and the source of the mitigation project idea.

6.4.2 Mitigation Action Plan
The mitigation action plan developed by the planning team includes the action items that the City intends to implement during the next five (5) years, assuming funding availability. The action plan, shown in Tables 6-4 to 6-13, includes the implementing department, an estimate of the timeline for implementation, and potential funding sources.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
205
The new mitigation actions include a broad range of approaches to hazard mitigation such as retrofitting, code enforcement, development of new regulations, public education, development of redundant facilities, and others. Measures are included to mitigate risks to existing buildings and infrastructure, as well as new buildings and infrastructure. The mitigation action plan assigns primary responsibility for each of the action items to an implementing department. The implementing department is the controlling department that will assign funding and oversee activity implementation, monitoring, and evaluation.
The planning team does not presume the expertise to prescribe which projects will be implemented. Prioritization of projects in the LHMP is a means to provide a basis for implementing the mitigation strategies, but all new mitigation actions and projects will be formally prioritized and selected by the implementing department. This will accommodate the project funding, schedule of the department, staff requirements, and ability to integrate the new project into existing and ongoing projects. Departments will consider the funding source, the cost-effectiveness of the project, alternative projects, the compatibility of the new project with ongoing projects, the extent to which the project addresses the risks assessed in Section 4, and the potential of economic and social damage.
Prioritization
To assist with implementing the mitigation action plan, the planning team used the following ranking process to provide a method to prioritize the projects for the Action Plan. Designations of High, Medium, and Low priorities have been assigned to each action item using the following criteria.
Does the action
• Solve the problem?
• Address vulnerability assessment.
• Reduce the exposure or vulnerability to the highest priority hazard? • Address multiple hazards?
• Offer benefits that equal or exceed costs?
• Implement a goal, policy, or project identified in the General Plan or Capital Improvement Plan?
Can the action
• Be implemented with existing funds?
• Be implemented by existing state or federal grant programs? CITY OF PASADENA 2025 Local Hazard Mitigation Plan
206
• Be completed within the five (5)-year life cycle of the LHMP? Will the action
• Be implemented with currently available technologies? • Be accepted by the community?
• Be supported by community leaders?
• Adversely affect segments of the population or neighborhoods. • Require a change in local ordinances or zoning laws?
• Result in a positive or neutral impact on the environment? • Comply with all local, state, and federal environmental laws and regulations? Is there
• Sufficient staffing to undertake the project?
• Existing authority to undertake the project?
Each positive response is equal to one point. Answers to the criteria above determined the priority according to the following scale:
1–6 = Low priority
7–12 = Medium priority
13–18 = High priority
Benefit-Cost Analysis
Conducting benefit/cost analysis for a mitigation activity can assist the City in determining whether a project is worth undertaking now in order to avoid disaster-related damages later. Cost- effectiveness analysis evaluates how to best spend a given amount of money to achieve a specific goal. Determining the economic feasibility of mitigating hazards can provide decision-makers with an understanding of the potential benefits and costs of an activity, as well as a basis for comparing alternative projects.
Funding
The funds required to implement the mitigation action plan will come from a variety of sources, including Federal Hazard Mitigation Grants, City budget, bonds, fees and assessments, and others. Some projects are (or will be) included in capital improvement budgets, while some, especially ongoing projects, are included in department operating budgets.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan
207
Prior to beginning a project or when federal funding is involved, the implementing department will use a FEMA approved benefit/cost analysis approach to identify the actual costs and benefits of implementing these mitigation actions. For non-structural projects, implementing departments will use other appropriate methods to weigh the costs and benefits of each action item and then develop a prioritized list.
Implementation
Mitigation projects were assigned to one of three (3) categories as a tentative schedule for implementation: short-range, mid-range, and long-range. Projects that are currently being implemented by various departments are assigned to the ongoing category.
Implementation of short-range projects will typically begin within the next three (3) years.
Mid-range projects will require some planning and likely require funding beyond what is currently allocated to the various departments in the City’s Operations and Maintenance budget. Projects in the mid-range category will generally begin implementation in the next three (3) to five (5) years. Long-range projects will require great planning and funding and will generally begin implementation within five (5) years and beyond.
Incorporation into Other Plans
The 2025 LHMP will be coordinated with and integrated into the following other planning mechanisms.
• The City EOP contains a list of hazards. The LHMP provides a similar, more detailed description of these hazards. Updates to the LHMP can inform revisions to the EOP. Hazards in both plans should be corroborated. • The American Water Infrastructure Act Risk required Risk and Resiliency Assessment (RRA) and the LHMP both should use the same source data and similar language to describe hazards that are contained in both. Hazard analysis and risk/vulnerability updates to one document should be reviewed for inclusion in both. For the 2021 LHMP, the planning team used portions of the RRA to develop new mitigations actions.
• The City will review the mitigation action plan in the LHMP as it updates its CIP.
Several mitigation actions address facility improvement and resiliency. Grant funding for these projects may support CIP project.

SECTION 7: PLAN MAINTENANCE PROCEDURES
Implementation and maintenance of the plan is critical to the overall success of hazard mitigation planning. This section details the process that the City will use to monitor, update, and evaluate the plan within the five-year cycle of the plan’s revision to ensure the LHMP remains an active and relevant document. The format of the plan aligns with the regulation checklist and is divided into sections of information. When it is time to maintain or revise the LHMP, data can be easily located and incorporated, resulting in an easy method to keep the plan current and relevant.
The planning team represents City staff from each department and other stakeholders that contributed to the development of the 2025 LHMP. The planning team oversaw the development of the plan and made recommendations on key elements of the plan, including the maintenance strategy.
It was important to the City that each department be represented in the planning team and given the opportunity to provide input during the plan’s development. This philosophy will continue for future plan revisions through evaluations, maintenance, and updates of data, processes, and programs. The planning team will convene annually to perform annual reviews of the LHMP and its implementation. The planning team will include representation from residents, citizen groups, partner agencies and stakeholders within the planning area.
If planning team members can no longer serve the planning team, the City Manager will assign another staff person to be on the planning team so that every City department is represented.
7.1 Monitoring and Evaluation
The hazard mitigation plan includes a range of action items to reduce losses from hazard events. Together, the action items provide a framework for activities that the City can choose to implement over the next five years. The effectiveness of the plan depends on the incorporation of the action items into existing City plans, policies, and programs. Although the City Fire Department will have primary responsibility for the LHMP’s continual review, coordination, and promotion, plan implementation, and evaluation will be a shared responsibility among all departments and agencies that contributed to the mitigation action plan.
The City Emergency Manager and Department Supervisors will be jointly responsible for the plan’s implementation and maintenance through existing City programs.
Department Supervisors will be responsible for implementing mitigation strategies and CITY OF PASADENA 2025 Local Hazard Mitigation Plan
223
actions specific to their department operations. The City Emergency Manager will assume the lead responsibility for facilitating plan maintenance and coordinating the planning team.
Each April, the planning team will begin the process of reviewing the LHMP and the implementation of mitigation actions to develop an annual progress report. This process can also assist the budget review process by providing information on mitigation projects and activities that have been completed or implemented. The annual progress report process will serve to align annual reviews of the hazard mitigation plan and to incorporate information. As updates to the LHMP are completed, the public will be made aware of the changes to the LHMP and make recommendations or comments.
The planning team will monitor and evaluate the hazard mitigation strategies during the year, and at a meeting held in January of each year, team members will provide information for the evaluation of the progress of the 2025 LHMP. The Emergency Manager will convene the planning team and lead the effort for the annual evaluation.
This evaluation will include:
• A summary of any hazard events that occurred during the prior year and their impact on the planning area
• A review of successful mitigation initiatives identified in the 2025 plan • A brief discussion about the targeted strategies that were not completed • A re-evaluation of the action plan to determine if the timeline for identified projects needs to be amended, and the reason for the amendment, e.g., funding issues
• Any recommendations for new projects
• Any changes in or potential for new funding options (grant opportunities) • Any impacts of other planning programs or initiatives in the City that involve hazard mitigation
The planning team will write a progress report that will be provided to the City’s budget planning team for review and incorporation in the budget process as mitigation projects are completed or implemented. The hazard mitigation plan progress report will also be posted on the City website on the page dedicated to the hazard mitigation plan, provided to the local media through a press release, and presented in the form of a report to the City Council. The planning team will strive to complete the progress report process by March of each year.
CITY OF PASADENA 2025 Local Hazard Mitigation Plan

7.2 Plan Update
Section 201.6.d.3 of 44CFR requires that local hazard mitigation plans be reviewed, revised as appropriate, and resubmitted for approval in order to remain eligible for benefits awarded under the Disaster Mitigation Act. The City intends to update its hazard mitigation plan on a five-year cycle. Based on needs identified by the planning team, the update will, at a minimum, include the following elements:
• The hazard risk assessment will be reviewed and updated using the most recent information and technologies
• The action plan will be reviewed and revised to account for any initiatives completed, dropped, or changed and to account for changes in the risk assessment
• Any new City policies identified under other planning mechanisms, as appropriate
• The draft LHMP update will be sent to appropriate agencies and organizations for comment
• The public will be given an opportunity to comment on the updated version prior to adoption
• The City Council will adopt the updated plan
At a minimum of six months before the expiration date of the 2025 LHMP, the planning team will implement a plan revision schedule to formally update the 2025 plan. The plan will be revised using the latest FEMA hazard mitigation guidance documents, such as the Mitigation Planning Tool and Regulation Checklist, to ensure compliance with current hazard mitigation planning regulations.
The overall success of the LHMP is through implementation of the plan’s hazard mitigation strategy and activities to reduce the effects of hazards, protect people and property, and improve the City’s efforts to respond to and recover from disasters.
Members of the public and the City will ultimately benefit from the implementation of the LHMP and must be given the opportunity to provide input to the continuous cycle of LHMP planning.
7.3 Continued Public Involvement
The overall success of the LHMP is through implementation of the plan’s hazard mitigation strategy and activities to reduce the effects of hazards, protect people and CITY OF PASADENA 2025 Local Hazard Mitigation Plan

property, and improve the City’s efforts to respond to and recover from disasters.
Members of the public and the City will ultimately benefit from the implementation of the LHMP and must be given the opportunity to provide input to the continuous cycle of LHMP planning.
The City will strive to keep the public aware of hazard mitigation projects that take place as a result of the LHMP. Public information will be released through press releases, City website announcements, public hearings as required, council meetings, social media, and press releases.
Projects that mitigate hazards are included in the City’s annual budget planning process. The public is made aware of the planning through City Council meetings and press releases during this time. The budget planning process will serve as an annual opportunity to conduct outreach to the public on updates to the hazard mitigation planning process.
A survey can be conducted to gather input on how the community feels about the progress being made on LHMP activities. The City will also provide press releases and information about hazard mitigation projects to the public regularly. At a minimum, the public will be engaged to learn about current LHMP activities and given the opportunity to provide comments and information on an annual basis to update and maintain the LHMP. The City PIO and the City Emergency Manager will be responsible for ensuring the public is included and involved in the annual public plan update and outreach.
When the time comes to begin revising the 2025 LHMP, the plan update process will be implemented, which will include continued public involvement and input through attendance at designated public meetings, web postings, through press releases to local media, community fairs, and events, and surveys. As part of this effort, a series of public meetings will be held, and public comments will be solicited on the revisions to the LHMP according to the five (5)-year cycle. Table 7-1 summarizes successful public involvement efforts previously conducted by the City, as well as proposed activities for public involvement and dissemination of information that shall be pursued whenever possible and appropriate.
