freeway and major community resources. Major arterial roadway cross-sections are shown on Figure 3-6.

Minor Arterial
Minor arterials are undivided 4-lane roadways that
provide left-turn pockets where needed for access.

They carry moderate volumes of vehicular traffic
and generally consist of less active frontages than
major arterials. Figure 3-7 depicts cross-sections of
designated minor arterial roadways.

Collector
Collectors are undivided 2-lane roadways that provide left-turn pockets where needed for access.

These roadways are intended to carry lower volumes
of vehicular traffic with lower posted speed limits.

Figure 3-8 displays collector roadway cross-sections.

Goods Movement
Goods movement routes play a pivotal role in maintaining economic vitality, ensuring efficient transportation, preserving infrastructure, enhancing safety, minimizing environmental impact, improving
quality of life, and supporting emergency response
efforts.

Goods movement at the intersection of Palomar Street and Wildomar Trail.

Proper planning and management of these routes
contribute to the City’s overall functionality and
well-being. The City of Wildomar does not have
designated goods movement routes. As part of this
planning effort, a review of goods movement patterns in Wildomar was conducted, and based on the findings, a network of goods movement routes has
been recommended, as shown on Figure 3-9.

Infrastructure and Utilities
The California Government Code stipulates that in
addition to transportation routes, the circulation element must identify the location and necessity of public utilities and facilities. The Elsinore Valley
Municipal Water District (EVMWD) provides
wastewater collection and treatment services, and
both EVMWD and the Farm Mutual Water Company supply potable water to city residents and businesses. CR&R Environmental Services collects solid and recycled waste, Southern California Edison
(SCE) provides electricity, and Southern California
Gas Company (SoCalGas) provides natural gas.

The Plan recognizes that a robust infrastructure and
utility network is paramount to accommodate the
growth and development that could occur from
buildout of the Land Use Plan. Systems that provide
for efficient management of water, wastewater,
stormwater drainage, solid waste, energy, and telecommunications will continue to be expanded concurrently with new development, population, and employment growth.

Figures 3-5 through 3-8), including the new “Rural
Collector” classification.

Policy CI 5.4
Level of Service Threshold. Although Vehicle
Miles Traveled (VMT) will be utilized as the traffic
impact metric for California Environmental Quality
Act (CEQA) review process, Level of Service (LOS)
is still a critical measure and indicator of traffic operations. LOS D shall be the threshold for all Circulation Element roadways and intersections, consistent with Transportation Impact Analysis (TIA) Guidelines adopted by the City Council, unless otherwise approved by the City Engineer.

Policy CI 5.5
Vehicle Miles Traveled Threshold. All projects in
the City shall be in compliance with Resolution No.
2020-40, Vehicle Miles Traveled (VMT) CEQA
Threshold Policy Guidelines. Efforts should be made
to reduce VMT by prioritizing pedestrian and bicycle travel and/or incorporating active transportation enhancements, to the extent feasible. Efforts to reduce VMT may not necessarily have to be implemented on-site; instead, in coordination with city staff, off-site projects can be identified that would
offset the VMT increase caused by a particular project. Applicants/developers would have the option to either construct the project/improvement or calculate
the costs associated with the construction of the project/improvement and pay that as an in-lieu fee.

Policy CI 5.6
Achieve Level of Service Threshold. All development projects shall achieve the LOS threshold identified in Policy 5.4; otherwise, the City reserves the right to request the proposed development to amend
existing roadway designations to ensure roadways
and intersections can adequately handle volumes of
traffic generated by the development.

Policy CI 5.7
Evaluate Roadway Network. As development occurs, evaluate the need to designate additional roads as Circulation Element roadways, or amend existing
designations to help enhance vehicle circulation, reduce congestion, and increase connectivity throughout the city. Measures shall not come at the
expense of pedestrian and/or bicycle safety, mobility, and access unless approved by the City Engineer.

Policy CI 5.8
Evaluate Intersections. Evaluate intersection geometrics and treatments at the intersections of Crescent Avenue/Elberta Road and Crescent Avenue/Olive Street to improve safety and operations. This could include, but not limited to, Crescent Avenue
Road closure to vehicular traffic at its northern (Elberta Road) and southern (Olive Street) ends.

Policy CI 5.9
Connect Lake Elsinore to Interstate 15. Continue
to coordinate with the City of Lake Elsinore and respective property owners in Wildomar to identify a preferred connection between Lake Elsinore and Interstate 15 via Bundy Canyon Road, or alternatives.

This connection could help reduce cut-through traffic on local or Collector streets in Wildomar and capitalize on the region’s investment in Bundy Canyon Road.

Policy CI 5.10
Interchange Projects. Ensure that future interchange projects, such as the Bundy Canyon Road and Wildomar Trail Project Study Reports, incorporate recommended bicycle network and pedestrian route type features, to the extent possible.

Policy CI 5.11
Evaluate Traffic along Bundy Canyon. Evaluate
local and regional traffic as development continues
along the Bundy Canyon Road/Scott Road corridor
to ensure adequate north-south connectivity along
the corridor to facilitate expected traffic volumes
and circulation and determine when improvements
are warranted to proposed or potential north-south
connections, as shown on the Proposed Network exhibit (as shown on Figure 3-4).

Policy CI 5.12
Utilize Transportation Demand Management.

Regularly update the Transportation Demand Management (TDM) ordinance to include best E-78

4. Economic Development
Element

4.1 Vision
This Element supports the economic health and resilience of Wildomar’s businesses, residents, and City finances in myriad ways. Wildomar will continue to support the growth of existing businesses and new start-ups by improving access to business
management, financing, and marketing training and
assistance. Economic development efforts will focus
on businesses that bring new dollars into the local
Wildomar economy and that capitalize on unique assets in and near Wildomar. The City will collaborate with schools and colleges to encourage training and
jobs for residents. It will also support access to resources and education for entrepreneurs.

The City will embrace innovative and creative approaches to nurturing a vibrant local economy while remaining fiscally responsible. Existing commercial
areas will be transformed and new commercial areas
developed, with a focus on experience-oriented
shopping. Emerging creative and artisan fabricator
economies and ancillary retail sales and services will
be accommodated in light industrial districts. The
City will also leverage the benefits from commuting
residents working from home and spending more
money locally.

4.2 Purpose
Because an economic development element is optional under California planning requirements, there are no legal standards for what the element should
contain. Although economic growth is essential to a
fiscally sustainable city, there are limitations on
what a city can do to promote and support economic
development.

In addition to identifying goals, policies and implementation actions the City will undertake to advance economic development, this element also outlines
the structure of how Wildomar will pursue and invest in economic development. There are two key reasons for this. First, much of the work of economic
development is conducted by local and regional partners, with the city playing a coordinating and supporting role. And second, most of the economic development programs and projects in which the City will invest will be formulated, implemented, and
evaluated through an economic development strategic plan, which the City will adopt and periodically update. The Economic Development Element provides policy guidance for economic development partnerships and for economic development strategic
planning.

4.3 Planning Context and
Approach
A market study was conducted to support the preparation of the General Plan. Rather than discussing the market conditions at that time—market conditions that will change often over the life of the Plan—there are three (3) broad trends that will influence growth and land development over the long term.

Smaller Households and Fewer Children
From 2010 to 2020, the number of households in
Wildomar with children at home declined—for both
married couples and single parents. This is a trend
throughout most of Western Riverside County, reflecting declining birth rates since 2007 and the lowest fertility rates ever in the US. The California Department of Finance (DOF) projects continuing declines in the number of Riverside County residents aged 18 and under and those aged 18 to 24. Reflecting these changes, the Southern California Association of Governments (SCAG) is projecting a longterm decline in the average household size.

E-83
1859
Wildomar 2040 General Plan
Public Hearing Draft

This shift in household size and type has implications for housing development. With cities accommodating fewer and fewer families with children, the regional market will shift towards producing a variety of housing types instead of predominantly large single-family detached houses, such as smaller
houses, multigenerational housing, and more attached and multifamily housing. This shift also has implications for the types of businesses—retail, dining, entertainment, and recreation—that will fill commercial buildings and be successful in Wildomar. Finally, this shift will have implications for the types of public facilities and services the City
will be expected to provide.

Changing Retail Environment
The 20+ year trend of retail spending shifting from
bricks-and-mortar stores to online purchasing accelerated with the COVID-19 pandemic (beginning in 2020). At the time this General Plan is being prepared, most chain retailers are highly focused on omni-channel retailing—creating multiple pathways
to retail sales, including in-store shopping and online sales with store pickup, delivery, and shipping from
centralized warehouses—which will reduce the need
for more physical stores. Even though Wildomar is
underserved by retail businesses (and so residents
often go to other cities to purchase goods), the proximity of competing shopping centers close to Wildomar will further diminish future demand for more commercial development in the City.

The Barn business plaza (top) and Montague Brothers Coffee (bottom).

To be competitive in the regional market and in the
changing retail environment, the City will need to
facilitate the transformation of existing commercial
areas and the development of new ones, with a focus
on experience-oriented shopping (shopping where
socializing, entertainment, activities, and the overall experience are as important, if not more so, as the
purchase of goods). Promoting the creation of new
local businesses will help expand offerings for shopping, dining, entertainment, and recreation in Wildomar.

Changing Office Use
The COVID-19 pandemic forced the development of
technology and changes in common business
To be competitive in the regional
market and in the changing retail
environment, the City will need to
facilitate the transformation of existing commercial areas and the development of new ones, with a
focus on experience-oriented
shopping (shopping where socializing, entertainment, activities, and the overall experience are as
important, if not more so, as the
purchase of goods).

practices to deal with employees forced to work
from home. Although businesses are still adjusting
to the new realities, it appears that some office workers may continue to work at home with a limited amount of in-office work. However, some officebased sectors of the economy will continue to operate primarily in offices. This includes medical services, which are forecast to account for the largest share of job growth.

City Hall is co-located with other offices in the Oak Creek shopping center.

Because Wildomar has a limited amount of office
space, it is unlikely to be impacted by a regional lack of demand for offices as businesses decrease their
office footprints when current leases expire. The
City will benefit from commuting residents working
from home and consequently spending more money
locally. And the demand for medical office space
can support mixed-use development in areas this
Plan designates for such development.

Industrial Land Use
Even though there is strong regional demand for
warehousing development, there is little land area
suitable for large warehouses in Wildomar, and
significant growth in warehousing is not consistent
with the community’s character and vision. Instead,
this General Plan focuses on supporting and facilitating light industrial/flex space, which offers smaller tenant spaces, and small- to medium-sized manufacturing facilities. This Plan also proposes to expand what “light industrial use” encompasses to include
the creative and artisan fabricator economies and ancillary retail sales and services. Implementation of the Economic Development Element should focus
on attracting relevant businesses, supporting entrepreneurs wanting to start new businesses, and maintaining the affordability of light industrial building space. Economic development efforts will focus on
businesses that bring new dollars into the local Wildomar economy and that capitalize on unique assets in and near Wildomar.

4.4 Economic Development
Strategic Planning
This Economic Development Element is predicated
on the City adopting, implementing, and periodically
updating an economic development strategic plan.

The strategic plan will identify specific projects, programs, and other investments that are realistic for the City to complete in three to five years. The strategic
plan will also establish an evaluation framework and
metrics to measure the effectiveness of the plan. And
with the information from implementation, the City
will adjust and amend the strategic plan.

This Plan also proposes to expand
what “light industrial use” encompasses to include the creative and artisan fabricator economies and
ancillary retail sales and services.

4.5 Economic Development
Partners
The City may partner with stakeholders that include
but are not limited to, existing businesses, property
owners, real estate brokers and developers, and other
community organizations. Other stakeholders are
key assets that economic development efforts will
capitalize on, such as Inland Valley Hospital. Other
stakeholders who do not necessarily have economic
development as a primary function will still likely be
engaged because they have a vested interest in
growth and diversification of the local economy and
are committed to the future of Wildomar. The City
will engage stakeholders through the strategic planning process, and the economic development strategic plan will reflect the specific projects and programs to which these stakeholders are committed.

In addition, the City will need to collaborate with a
wide variety of economic development organizations
and service providers to leverage their expertise and
federal, state, and non-profit funding. Through these
partnerships, the City will seek to connect existing
businesses, firms interested in locating in Wildomar,
and local entrepreneurs starting new businesses, with
training and assistance. A partial list of partners includes the Economic Development Coalition, Riverside County Office of Economic Development, Riverside County Workforce Development (RCWD), Inland Empire Small Business Development Center,
Inland Empire Center for Entrepreneurship, Murrieta/Wildomar Chamber of Commerce, Lake Elsinore Unified School District, and Mt. San Jacinto Community College District. The list is expected to
change over the lifetime of the General Plan.

5. Open Space and
Conservation Element

5.1 Vision
The open space and conservation element seeks to
balance human activities with the integrated ecosystem of plants and animals that use the same air, water, energy, and natural resources.

Wildomar has the good fortune to contain a bounty
of natural resources and open spaces. It is home to
scores of native animals and plants and the habitats
that nurture their lives. And it is shaped by natural
features—from the hillsides to the valleys to the watercourses that give the City its unique form and character. The land also bears the traces of people
who inhabited the area in times past.

The policies in this element recognize that Wildomar’s unique natural and cultural resources are irreplaceable and seek to minimize impacts on them from the daily activities of its human inhabitants so
that they can be enjoyed by subsequent generations
of residents.

5.2 Purpose
This element responds to the requirements in the
California Government Code §65560 et seq. and
§65302(d). It overlaps with several other elements,
most notably the Land Use Element when determining the suitability of sites for future development; the Recreation and Community Services Element
when considering access to open spaces for recreation, parkland, and trails; and the Safety Element to address open space for health and safety.

Residents value Wildomar’s open spaces and natural features.

Relationship to Other
Planning Efforts
The policies in the Open Space and Conservation Element support the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) and Stephens’ Kangaroo Rat Habitat Conservation
Plan (SKRHCP), which seeks to protect habitat for
the Stephens’ kangaroo rat, an important keystone
species.

Western Riverside County Multiple Species
Habitat Conservation Plan
The MSHCP focuses on conserving species and their
habitats in western Riverside County. In conjunction
with other habitat conservation plans in Southern
California, the goal of the MSHCP is to maintain biological and ecological diversity within a rapidly urbanizing region. MSHCP-conserved lands in the City are shown on Figure 5-1.

The policies in this element recognize that Wildomar’s unique natural and cultural resources are irreplaceable and seek to minimize impacts on them from the daily activities of its human inhabitants… E-93

5.3 Planning Context and
Approach
Open Spaces and Natural
Resources
The City of Wildomar is nestled in a valley bordered
by rolling hills to the east and the Cleveland National Forest and Santa Ana and Elsinore mountains to the west. Murrieta Creek and its important riparian corridor runs north-south through the City. The surrounding natural topography and environment afford views of natural open spaces, a rich biodiversity, and miles of mountain ridgelines, which this Plan endeavors to protect as scenic resources.

As shown on Figure 5-1, 1,122 acres of wildlife conservation areas are scattered throughout the northeastern part of the City. These conserved open spaces serve multiple functions, including the protection of natural open areas, watersheds, environmentally sensitive areas such as creeks and riparian areas, wildlife habitats, hillsides, and visual resources.

The City’s distinct vegetation communities are
shown on Figures 5-2a through 5-2d. A total of 36
special-status plant species and 42 special-status
wildlife species have been documented to occur in
the City or may be potentially affected by activities
in the City. Critical habitats for the City’s sensitive species are shown on Figure 5-3. Aquatic resources
are shown on Figure 5-4. These features have the potential to provide corridors that encourage the movement of wildlife and provide habitat for sensitive wildlife and plant species. Because these sensitive
habitats are generally limited to the natural drainages and conserved areas where development is limited,
they are deserving of continued protection.

Wild poppies color the City’s open spaces in spring.

Mineral Resources
The City is designated as Mineral Resources Zone 3
(MRZ-3), which indicates that significance of mineral deposits cannot be determined from the available data. A mining pit, Bundy Canyon Pit, is currently operational. Additionally, a federal lode mining claim, the Baxty Queen, conducts small-scale prospecting and mining for mineral resources, including rare earth elements (REEs) and precious gem materials. These facilities are depicted on Figure 5-5.

Air Quality
Clean air is a critical component for everyday living.

Wildomar is under the jurisdiction of the South
Coast Air Quality Management District (AQMD),
which includes Los Angeles, Orange, Riverside, and
San Bernardino Counties. South Coast AQMD is responsible for controlling emissions from stationary sources of air pollution.

E-94

Wildomar 2040 General Plan
Public Hearing Draft

Exposure to high levels of air pollution can result in
severe health impacts, such as respiratory and cardiovascular disease, asthma, and premature death. Protecting the City’s air is thus a vital part of promoting community health. However, air doesn’t recognize
municipal boundaries. So the policies and programs
in this element encourage responsible air management through collaboration with local and state air quality agencies, imposing air pollution regulations
on new construction, and paving the way to use lesspolluting vehicles and outdoor equipment.

Water Supply and Quality
In addition to clean air, the City needs a clean and
adequate supply of water. The Elsinore Valley Municipal Water District (EVMWD) provides water services to Wildomar. EVMWD’s water supply is a
blend of local groundwater, surface water from Lake
Elsinore and Railroad Canyon Reservoirs (Canyon
Lake), and imported water.

While EVMWD provides the water, the City is responsible for ensuring that water is used responsibly.

This Plan ensures both the protection of water quality in the City and continued collaboration with EVMWD to reduce water use.

Energy
Energy resources provide the power to keep our
electronics running and buildings operating, help us
keep cool in the summer heat, and power our critical
and emergency services. Most of the energy used in
Wildomar’s buildings is in the form of electricity,
provided by Southern California Edison (SCE), and
natural gas, supplied by Southern California Gas
Company (SoCalGas).

Wildomar promotes energy efficiency and conservation through participation in the Western Riverside Energy Partnership, a Western Riverside Council of
Governments (WRCOG) initiative that brings SCE
and SoCalGas together with local jurisdictions to
achieve energy savings, reduce energy bills, and improve building comfort.

The General Plan’s energy policies and implementation programs support the development of affordable, reliable, and independent local power. Policies to promote energy conservation will help lower bills
for energy customers, ensure that buildings remain
comfortable during all weather conditions, and manage the transition to move diverse power sources.

Solid Waste
Proper solid waste treatment and disposal contribute
to safer and healthier environments for people to live
in. In Wildomar, CR&R Services collects and disposes of solid waste generated by households and businesses. CR&R provides trash collection, recycling, and organics processing services and employs anaerobic digestion techniques to produce natural
gas from organic waste.

The solid-waste-related policies and implementation
programs in this element aim to help reduce the
amount of waste that Wildomar sends to landfills.

This includes efforts to divert organic materials and
other recyclables into composting or other recycling
programs as well as overall waste reduction efforts.

Greenhouse Gas Emissions
The buildup of greenhouse gases (GHG) in the atmosphere is a factor in climate change. Climate change is responsible for an increase in severe
storms and weather that can make some natural hazards, such as floods, droughts, and wildfires, occur more frequently and with greater intensity. Activities
that produce GHGs include the use of gas-powered
vehicles such as cars and trucks, electricity and natural gas use in local buildings, and the decomposition of materials in landfills. California is working toward a goal of carbon neutrality by 2045, and Wildomar has a role to play in meeting those targets by reducing GHG emissions.

As with other communities across California, Wildomar has a responsibility to reduce GHG emissions and improve climate resiliency. Policies and implementation programs in this element will help guide the reduction of GHG emissions and provide a path
E-104
1880

5. Open Space and Conservation Element
Public Hearing Draft
October 2024 Page 5-13
to increased resiliency to climate hazards like drier
summers, more intense flooding, and more frequent
wildfires. Policies in other elements, such as Safety,
work in concert to reduce vulnerability to climate
hazards. Through these policies and implementation
programs, along with the efforts in the Subregional
Climate Action Plan, Wildomar can significantly reduce its GHG emissions and support progress toward California’s adopted GHG reduction targets.

Cultural and Historical
Resources
Wildomar is part of the ancestral lands of the
Pechanga and Soboba Tribes, both federally recognized tribes. For more than 10,000 years, the Pechanga People have called the Temecula Valley,
which includes Wildomar, their home. The Soboba
tribe has lived within the present-day San Jacinto
Valley and surrounding areas for centuries.

The Built Environment Resources Database lists 14
properties in the City whose dates of occupancy or
construction are between the years 1885 and 1940,
and which range in type from single-family homes to
health resorts, as shown in Table 5-1. Although none
are currently listed on the California Register of Historical Resources (CRHR) or National Register of Historic Places (NRHP), four resources have been
evaluated as potentially eligible for listing, with a
status code of 3S.

6. Recreation and
Community Services
Element

6.1 Vision
Parks, trails, recreation facilities and programs, and
community services nurture the social, physical, and
mental well-being of Wildomar’s residents. The
Recreation and Community Services Element supports
a vision of an expanded network of parks and trails,
enhanced recreation activities, and robust community
services that continue to support the healthy lifestyles of Wildomar’s current and future generations.

The City will provide a network of parks and
recreational facilities that contribute to individual
health by supporting physical activity and access to the mentally restorative powers of nature. Public facilities and community services such as libraries, schools, and
arts and cultural programs will enrich the mind and
connect neighbors with each other. Wildomar will
work with its partners to provide a backbone of public
safety and medical services that maintain a high
quality of life for the City’s residents.

6.2 Purpose
This element addresses California Government Code
requirements (§ 65560 et. seq.) to assess open space
for outdoor recreation and works in concert with the
Land Use Element and Open Space and Conservation
Element. Other topics addressed in the element are not
required by government code but represent the City’s
commitment to maintaining and improving
recreational and community facilities and programs to
support the social, physical, and mental well-being of
its residents.

Relationship to Other Planning Efforts
This element is intended to set the overall policy
framework for the growth and development of
recreational and community services in Wildomar.

However, it builds upon several other important
planning and policy documents.

Wildomar Parks Master Plan
The City prepared the Wildomar Parks Master Plan
(WPMP) in 2015. The plan offers a vision and specific
actions that the City can undertake to acquire land and build a parkland system that meets residents’
recreational needs.

Wildomar Active Transportation Plan
The Active Transportation Plan (Wildomar ATP)
contains strategies and recommendations for multi-use
trails, including equestrian access, as well as bicycle and pedestrian networks for both recreation and
mobility purposes.

Murrieta Creek Regional Trail Project
Wildomar is a partner in the regionwide Murrieta
Creek Regional Trail Project. The project envisions a
multi-use, non-motorized trail system along the creek
that connects the cities of Temecula, Murrieta,
Wildomar, and Lake Elsinore, and echoing the route of
the historic Butterfield Overland Trail.

This Element supports a vision of an
expanded network of parks and
trails, enhanced recreation
activities, and robust community
services that continue to support
the healthy lifestyles of Wildomar’s
current and future generations.

6.3 Planning Context and
Approach
Parks and Recreation
The City’s current parkland system and recreational
open spaces consist of four public parks, recreation
facilities at the parks and on joint-use land, and trails that serve as recreational and transportation routes.

The four parks in the city are Marna O’Brien Park,
Regency-Heritage Park, Windsong Park, and Malaga
Park, and they cover more than 15 acres of parkland.

Play structure at Marna O’Brien Park.

The City has three new parks in the planning stages. A
27-acre park is planned adjacent to Ronald Reagan
Elementary School, and an 11-acre park is planned
along Grand Avenue, adjacent to David A. Brown
Middle School. Both parks are planned for a mix of
active and passive elements. A 20-acre park is planned
on the eastside of Palomar Street, generally south of
Pasadena Street adjacent to Gierson Avenue. The park
has been proposed as a passive nature park with trails
and supporting amenities.

Existing and proposed parkland facilities are shown on
Figure 6-1.

The City has several facilities for organized sports
play or other recreational activities. Marna O’Brien
Park has three (3) baseball fields with spectator and
player benches, two (2) full basketball courts, two
large multi-use soccer fields, and sports field lighting; while Regency Heritage Park has two (2) basketball
half courts and a dog park. Both parks have a tot-lot.

There are also recreational facilities owned by other
entities that help to meet the community’s recreational needs. These include the ball fields at the Wildomar
Cemetery and recreational amenities at public school
grounds that may be made available to the public after
school hours on weekdays and on the weekend.

The goals and policies in this Element supplement the
Wildomar Parks Master Plan (WPMP) by providing an
overall vision for the provision of parks and
recreational facilities in the City and addressing topics not included in the WPMP. New parks will be
designed to be safe, sustainable, and inclusive to
accommodate residents of all ages, backgrounds, and
abilities. While expanding access to such facilities, the City will strive to serve neighborhoods with the
highest unmet needs. This expansion will be abetted
by creative approaches to joint use opportunities and
funding sources.

Trails
Wildomar has a network of multi-use and equestrian
trails that serve as both recreational facilities and
transportation routes for pedestrians, hikers, and
cyclists. The trails connect to different parts of
Wildomar and regional trail networks. Existing and
proposed trails are shown on Figure 6-2.

The vision for managing noise in
Wildomar is to allow the ”good
noises” associated with a vibrant
city full of life and limit the impact
of the ”bad noises”

7. Noise Element

7.1 Vision
The vision for managing noise in Wildomar is to
allow the ”good noises” associated with a vibrant
city full of life and limit the impact of the ”bad noises” that occur infrequently as a part of that life so that there are still quiet places to sleep, relax, and
recharge.

People’s relationship to noise can be complicated.

Certainly, noise can be unwelcome at times, but
places that are full of life are often noisy. People
make noise going about their daily routines as they
move about, use equipment, build things, talk, sing,
shout, and laugh. People also play music, cheer for
sports, have dogs, and generally make themselves
known. These are sounds of life and are welcome in
most instances. Anyone with children or experience
near a school during recess understands. To most,
these are good sounds and would not be considered
noise in the right context.

Noise becomes a nuisance when it regularly disturbs
sleep, discourages the enjoyment of the outdoors,
and affects the daily routine of residents. When this
occurs, it is essential to lower the level of noise.

7.2 Purpose
California Government Code § 65302(f) requires
municipalities to prepare and adopt “a Noise Element that shall identify and appraise noise problems in the community.” The Noise Element supports development locations of planned noise-sensitive land uses and facilitates noise levels for sensitive noise
receivers. For purposes of this Noise Element,
"noise-sensitive areas and uses" include residential
areas, parks, schools, churches, hospitals, and longterm care facilities. It is also important that noise generating uses such as industrial and commercial be
protected from incursion of noise-sensitive uses to
avoid noise complaints that may affect the operation
of these fixed noise sources.

7.3 Noise
At the basic level, noise is defined as unwanted
sound and is known to have several adverse effects
on people, including hearing loss, speech and sleep
interference, physiological responses, and annoyance. Although sound can be easily measured, the perception of noise and the physical response to
sound complicate the analysis of its impact on people. People judge the relative magnitude of sound sensation in subjective terms such as “noisiness” or
“loudness.”
Noise also uses specific terminology to describe levels of noise and how measurements are taken and compared. Noise also reacts to the environment and
can be reduced through barriers such as walls, buildings, and topography. The most obvious noise source in the City is traffic from I-15 and major roadways
such as Clinton Keith, Bundy Canyon, and Wildomar Trail.

7.4 Terminology
Like many technical fields, specific terms are used
to explain different aspects of analysis. For noise,
understanding the following terms will help when
reading this element.
• Decibel (dB)
This is a unit for measuring the amplitude of a
sound that is based on a logarithmic scale, which
E-125
1901
Wildomar 2040 General Plan
Public Hearing Draft

compresses the wide range of sound pressure
levels to a more usable range of numbers.
• A-weighted decibels (dBA)
This refers to the sound pressure level in decibels as measured on a sound level meter using the A-weighting network. This method deemphasizes the very low and very high frequency components of the sound, placing greater emphasis on frequencies within the sensitivity
range of the human ear.
• Day-Night Average Sound Level (Ldn)
This noise measurement describes the average
noise level over a 24-hour period after the addition of 10 decibels to sound levels after 10 p.m. and before 7 a.m. The 10 dBA adjustment accounts for our greater sensitivity to nighttime noise and the fact that lower ambient levels at
night tend to make noise events, such as aircraft
flyovers, more intrusive.
• Community Noise Equivalent Level (CNEL)
Similar to Ldn, the CNEL is the 24-hour average
noise level after the addition of 5 dB to sound
levels from 7:00 p.m. to 10:00 p.m. and 10 dB to
sound levels between 10:00 p.m. and 7:00 a.m.
• Equivalent Continuous Noise Level (Leq)
Leq is a noise descriptor that can be thought of
as the average noise level during a period of
time. The average noise level is based on the energy content (acoustic energy) of the sound. It is typically computed over 1-, 8-, and 24-hour
sample periods.
• Noise Contours
Noise contours are a graphical representation of
projected noise exposure levels associated with
noise sources such as roadways, aircraft, and
railroad operations. They are expressed as the
physical distance from the noise source at which
different noise levels can be heard.

7.5 Noise Environments &
Measurements
All sound levels referred to in this element are Aweighted to de-emphasize the very low and very high frequencies in a manner similar to the human
ear. A-weighting gives a better measurement for human annoyance and some health effects.

Ambient noise, which is the total noise in an environment, is usually measured with an A-weighted decibel scale (dBA). However, ambient noise varies
over time; therefore, other metrics that give an average noise level over a specified period of time are used. Such metrics include the energy-equivalent
noise level (Leq), the day-night average noise level
(Ldn), and the community noise equivalent level
(CNEL). Leq is an hourly average, and Ldn and
CNEL are 24-hour weighted averages.

Ambient noise monitoring was conducted in October
2022 to determine a baseline noise level for different
environments. The results of the noise measurements
can be found in Appendix 5.13-1 of the General Plan
Environmental Impact Report.

7.6 Planning Context
Generally, Wildomar is a quiet town, and most noise
is associated with traffic. In a real sense, this means that noise levels are less during nights, weekends,
and holidays when traffic is less than normal daily
volumes. Tables 7-1 and 7-2 show the ambient noise
measurements recorded during preparation of this
element. Figure 7-1 shows the locations where
measurements were recorded. Roadway noise and
ambient noise are both important to understand because road noise helps guide land use decisions, and ambient noise provides a measurement against
which future noise generating uses will be measured.

7.7 Noise Standards
Interior Noise Standards
The State of California’s noise insulation standards
are codified in the California Code of Regulations,
Title 24, Building Standards Administrative Code,
Part 2, California Building Code. These noise standards are applied to new construction for the purpose of providing suitable interior noise environments.

Noise studies must be prepared when a project seeks
to place people near major transportation noise
sources, and where such noise sources create an exterior noise level of 60 dBA CNEL or higher. A project must demonstrate that structures have been designed to limit interior noise in habitable rooms.

Exterior Noise Standards
Table 7-3 provides the City with a tool to gauge the
compatibility of land uses relative to existing and
future noise levels. The noise standards can be modified for areas that already have higher noise, and for activities like festivals, markets, and outdoor performances. Generally, there is more flexibility for outdoor noise than indoor, and design features such
as berms, walls, windows, and setbacks will all be
factored into review of the project.

7.8 Noise Contours
Figure 7-2 shows the projected noise following the
roadways and potential segments of transportation
based on the traffic analysis prepared for the land
use diagram (Figure 2-2). The contours are calculated using predicted traffic data for the City roadways and do not factor in topography, other buildings, or
noise attenuation. While the contours may not be
able to precisely predict noise levels, they can be
used as a general guide to consider noise levels for
any future projects.

Aircraft Noise Levels
The closest airport to the City is the Skylark Airport
(Skydive Elsinore), a private airstrip with minimal
air traffic approximately 425 feet northwest of Wildomar’s western boundary. Air traffic is primarily from the 25 aircraft owned by Skydive Elsinore,
which are used to provide skydiving and gliding services. The small aircraft and limited flight operations do not generate significant noise affecting the City.

The nearest public airport is approximately 4.8 miles
southeast of Wildomar and is known as the French
Valley Airport.

Airport noise contours do not extend into the City’s
sphere of influence, and airport noise does not significantly affect nearby sensitive receptors (i.e., all residences are outside of the 55 and 60 dBA Ldn
noise contours. Therefore, while aircraft overflights
will be heard, the noise generated does not result in
the need to adjust land uses or activities in the City.

Roadway Noise Levels
Vehicular noise on roadways depends on speed, volume, and traffic conditions. Typically, vehicles moving slower in high traffic generate less noise than cars operating fast under low or no traffic conditions.

E-132

To establish the baseline noise conditions, traffic
data representing annual average traffic volumes for
existing conditions on major roadways were obtained from the regional traffic model to allow calculations for existing and projected traffic volumes.

Distances from the centerlines of selected roadways
to the 60, 65 and 70 dB CNEL contours are summarized in Table 7-4. These distances should be treated as estimates; actual distances may vary due to factors such as road curvature, roadway grade, shielding by local topography or structures, and elevated roadway.

7.9 Stationary Noise
Primary stationary noise sources during operation in
commercial and industrial zones could include loading docks, large mechanical equipment, and fabrication. Ideally these uses and activities are located away from sensitive receptors. Other noise sources
that affect people include nightclubs, outdoor dining
areas, gas stations, car washes, drive throughs, fire
stations, air conditioning units, swimming pool
pumps, school playgrounds, athletic and music
events, and public parks.

While new noise should be minimized, placing new
noise-sensitive land uses in areas subject to noise
currently or in the future should also be discouraged.

Noise-generating uses are often those that provide
jobs, manufacture goods, and services. It is important to protect these types of land use because encroachment of people into existing noise environments often shortens the longevity of the noisegenerating land use.

For future noise-generating uses, a project that cannot contain its noise within the property boundaries will need physical and operational features to address its noise. Ideally, these measures would be integrated with the overall project design and not added as an afterthought.

7.10 Construction Noise
Construction occurs as the City continues development and growth. Although beneficial to the City, the process generates temporary construction noise.

Noise from construction depends on the size of the
E-137
1913
Wildomar 2040 General Plan
Public Hearing Draft

project and how long it takes to build it, which could
be several years. Methods to minimize the impacts
of construction noise, such as setting reasonable
construction times and ensuring that mufflers and
noise suppression features of equipment are working, can help limit noise intrusion into adjacent areas. Engagement with the community is crucial for explaining noise and addressing noise concerns.

Even though construction noise is considered temporary, it can still result in impacts to adjacent uses.

The City’s noise ordinance restricts certain activities to specific days and times, but construction noise
may still disturb existing residents.

7.11 Vibration
Sources of vibration include natural phenomena
(e.g., earthquakes, volcanic eruptions, sea waves,
landslides) and those introduced by human activity
(e.g., explosions, machinery, traffic, trains, construction equipment). Vibration sources may be continuous (e.g., operating factory machinery) or transient (e.g., construction).

Usually vibration is a minor annoyance, but with
fragile buildings or certain sensitive uses, vibration
can cause damage or disrupt operations. Vibration
amplitudes are commonly expressed in peak particle
velocity (PPV) or root-mean-square (RMS) vibration
velocity. PPV and RMS vibration velocity are normally described in inches per second (in/sec) or in millimeters per second. PPV is defined as peak rate
of speed at which soil particles move (e.g., inches
per second) due to ground vibration, which shows
the maximum instantaneous positive or negative
peak of a vibration signal. PPV is typically used
when monitoring transient and impact vibration and
correlates well to the stresses experienced by buildings.

However, PPV is not always suitable for evaluating
human response. It takes time for the human body to
respond to vibration signals. The human body responds to average vibration amplitude. As with airborne sound, the RMS velocity is often expressed in decibel notation as vibration decibels (VdB). The
typical background vibration velocity level in residential areas is approximately 50 VdB. Ground vibration is normally perceptible to humans at approximately 65 VdB. For most people, a vibration velocity level of 75 VdB is the approximate dividing line between barely perceptible and distinctly perceptible
levels.

One of the impacts of construction is vibration that
people can feel. Vibration can be a short-term sensation, like when a heavy truck passes, but if several trucks were to pass by or machinery nearby creates a
constant vibration, the vibration can have negative
effects on people. What starts as a minor irritation,
over time turns into feelings of unease, disrupts
sleep, and becomes a constant annoyance that reduces the enjoyment people have in their homes. Vibration can also disrupt delicate procedures such as surgery and manufacturing.

Vibrations generated by construction activity can be
transient, random, or continuous. Transient construction vibrations are generated by blasting, impact pile driving, and wrecking balls. Continuous vibrations
result from vibratory pile drivers, large pumps, and
compressors. Random vibration can result from
jackhammers, pavement breakers, and heavy construction equipment. Table 7-5 describes the general human response to different ground vibrationvelocity levels.

7.12 Goals and Policies
GOAL N 1
A City with appropriate noise and vibration
levels that supports a range of places to promote the health, safety, and general welfare of the public and protects from adverse noise
impacts.

Policy N 1.1
Sound Design. Require the use of integrated designrelated noise reduction measures for interior and exterior areas prior to using noise barriers, buffers, or walls to reduce noise levels generated by or affected
by new development.

Policy N 1.2
Noise Compliance. Continue to require developments to comply with local, regional, and state building code regulations and standards, including
but not limited to the City's municipal code; Title 24
of the California Code of Regulations, including the
California Green Building Code; Occupational Safety and Health Administration, Federal Transit Administration, and Federal Highway Administration regulations; and subdivision and development codes.

Policy N 1.3
Noise Boundaries. Coordinate with the County of
Riverside and the cities of Lake Elsinore, Menifee,
and Murietta to minimize noise impacts from adjacent land uses along the City's boundaries, especially its rural edges.

Policy N 1.4
Noise Barriers. Discourage use of noise barriers and
walls constructed exclusively for noise-attenuation
purposes where possible. In instances where noise
barriers cannot be avoided, consider the use of site
planning and building material/design features in
conjunction with barriers to mitigate visual impacts
and reduce the size of barriers.

Policy N 1.5
Temporary Noise. Regulate temporary noise, such
as party noise, live events, playground noise, construction during the day and night (including concrete slab pouring), and barking dogs, through the City's municipal code.

Policy N 1.6
Construction Noise. Require development to minimize the exposure of neighboring properties to excessive noise levels from construction-related activity during all phases of construction.

Policy N 1.7
Vibration Assessment. Restrict the placement of
sensitive land uses in proximity to vibrationproducing land uses.

Policy N 1.8
Vibration Velocity Level. Require new development to generate operational and/or construction vibration levels no greater than 75 VdB at the property line of a sensitive receptor where feasible, as indicated in Table 7-4.

E-139
1915
Wildomar 2040 General Plan
Public Hearing Draft

GOAL N 2
Promote existing and future land compatibility with current and projected local and regional noise conditions.

Policy N 2.1
Land Use Compatibility. Require future developments to adhere to the land use compatibility standards in Table 7-3.

Policy N 2.2
Protect Noise-Sensitive Land Uses. Discourage
noise-sensitive uses in areas in excess of the listed
noise levels in Table 7-3.

Policy N 2.3
Guide Noise-Tolerant Use. Plan and promote noisetolerant land uses in noise-generating areas such as transportation corridors adjacent to I-15.

Policy N 2.4
Secure Noise-Producing Areas and NoiseSensitive Land Uses. Minimize nonresidential noise impacts on residential use and preserve areas of
noise-generating uses by limiting the incursion of
residential and noise-sensitive uses.

Policy N 2.5
Development Near Transportation Corridors. For
development in infill areas; near Riverside Transit
Agency Bus Lines (RTA bus); or along highways,
arterials, and collectors, allow an exemption from
exterior noise standards for secondary open space
areas (such as front yards, parking lots, stoops,
porches, or balconies) if noise standards can be met
for primary open space.

GOAL N 3
Promote reduction of noise from nontransportation-related sources on sensitive receptors.

Policy N 3.1
Noise Compliance. Ensure compliance with standards and procedures for mitigating constructionrelated activities that introduce excessive noise levels.

Policy N 3.2
Non-transportation Operation. Continue to require
future developments involving the use of stationary
equipment to comply with standards for regulating
noise levels for operation of the project and thresholds for any noise-sensitive receivers.

GOAL N 4
Curb traffic level noise increases near sensitive receivers and areas exceeding noise level standards by promoting safe and reasonable
truck traffic routes, alternative modes of
transportation, and adherence to regulations
for existing and future transportation noise
sources.

Policy N 4.1
Transportation Compliance. Require that future
transportation noise sources comply with the City’s
exterior noise levels.

Policy N 4.2
Truck Delivery Transport. Require that commercial or industrial truck delivery hours be limited when adjacent to noise-sensitive land uses unless
there is no feasible alternative or there are overriding transportation benefits.

10. Implementation
This section serves as a working checklist of
implementation programs for city staff and local
decision makers to ensure that the General Plan vision
is realized. An implementation program is an action,
procedure, program, or technique that carries out goals and policies. Implementation measures are
comprehensive in nature, encompassing amendments
of existing and preparation of new plans, ordinances,
and development of design standards; administration
of city procedures and development review and
approval processes; and interagency coordination.

The following tables describe the relevant actions and
programs to implement the Plan’s goals and policies
and identifies the corresponding policies, responsible
city departments, and the time frame for application.

The latter are expressed in four general time periods:
short refers to immediately following to within two
years of the General Plan’s adoption, medium refers to
three to five years, long to five years and longer, and ongoing to those actions that continue or are
periodically implemented through the life of the
General Plan.

The described programs and actions are intended to
inform and guide the development of the city’s annual
budget. During that time, city staff will review and
prioritize the level of expenditure necessary to carry
out the prescribed action and program. Completion of
a recommended implementation program will depend
on a number of factors such as citizen priorities,
finances, and staff availability.

To enable Wildomar’s General Plan to serve its
purpose effectively, the list of programs and actions
need to be reviewed, maintained, and implemented in
a systematic and consistent manner. At a minimum,
the programs and timeframes described in this chapter
should be comprehensively reviewed and updated at
least once every five (5) years to reflect available
fiscal resources, community needs, and priorities.

Revisions to these shall not constitute an amendment
of the General Plan, provided that they are consistent
with the Vision Statement and carry out its goals and
policies. As such, future revisions to this
Implementation Plan will not necessitate

However, Gov. Code § 65302(h)(1) requires that environmental justice goals, policies, and objectives integrated in other elements shall address the following:
a. Identify objectives and policies to reduce the unique or compounded health risks in disadvantaged communities by means that include, but are not limited to, the reduction of pollution exposure, including the improvement of air quality, and the promotion of public facilities, food access, safe and sanitary homes, and physical activity.
b. Identify objectives and policies to promote civic engagement in the public decision-making process. c. Identify objectives and policies that prioritize improvements and programs that address the needs of disadvantaged communities.

RE: Wildomar GPU – Goods Movement Memorandum

BACKGROUND
The goods movement sector plays a critical role in the local economy with 1 out of 7 jobs in Southern California involved in international trade. The Southern California Association of Governments (SCAG) region which encompasses the counties of: Los Angeles, Orange, Riverside, San Bernardino, and Ventura, is highly competitive in goods movement with its extensive network of seaports, airports, roadways, railways and intermodal transfer facilities. One of the most prevalent ways to transport goods is in the form of freight trucks, which typically navigate the transportation network of cities and counties via goods movements routes.

Goods movement routes hold significant importance due to several key factors:

Economic Vitality: Truck routes ensure the smooth flow of goods and services, which is crucial for maintaining a thriving local economy. These routes facilitate the movement of products to and from businesses, industries, and distribution centers, supporting commerce, trade, and job creation.

Transportation Efficiency: Designated truck routes are strategically planned to accommodate the larger size and weight of commercial vehicles. By guiding trucks along specific routes, traffic congestion can be minimized, preventing bottlenecks and delays. This leads to more efficient and reliable transportation of goods, reducing the time and costs associated with shipping and delivery.

Infrastructure Preservation: Heavy trucks can exert significant wear and tear on roads and infrastructure. By directing trucks to designated routes, cities can better manage and maintain their roadways. This helps prevent premature deterioration of streets and reduces the need for frequent repairs, ultimately saving taxpayer money.

Safety: Truck routes are designed with safety considerations in mind. These routes often avoid densely populated residential areas and prioritize roads with wider lanes and suitable turning radii for larger vehicles. This reduces the risk of collisions, ensures safer road conditions for both truck drivers and other motorists, and minimizes the impact on local communities.

Environmental Impact: Properly planned truck routes can help mitigate the environmental effects of heavy vehicle traffic. By guiding trucks away from sensitive areas and residential neighborhoods, air quality can be preserved, noise pollution can be minimized, and the overall environmental impact of goods movement can be reduced.

Goods Movement Memorandum
Quality of Life: Effective truck route planning enhances the quality of life for residents by minimizing the negative impacts of commercial traffic. Reducing congestion, noise, and pollution improves the overall living conditions in cities, making it a more desirable place to live and work.

Emergency Response: Clearly designated truck routes assist emergency responders by providing them with reliable pathways during crises. Unobstructed truck routes enable quicker responses to accidents, natural disasters, and other emergencies, ensuring the safety and well-being of residents.

In summary, truck routes play a pivotal role in maintaining economic vitality, ensuring efficient transportation, preserving infrastructure, enhancing safety, minimizing environmental impact, improving quality of life, and supporting emergency response efforts. Proper planning and management of these routes contribute to the cities’ overall functionality and well-being.

PURPOSE
Currently, the City of Wildomar does not have designated goods movement routes. Therefore, the purpose of this technical memorandum is to present a review of goods movement patterns for the City of Wildomar, to inform the technical analysis and planning process to identify and recommend goods movement routes.

LITERATURE REVIEW
The Literature Review discusses the following sources:
 City of Wildomar, California Municipal Code
 City of Wildomar, California Pavement Management Plan  City of Wildomar, California Pavement Management Report (2019)  City of Wildomar, California Pavement Management Program Update (2021)  California Vehicle Code (current)
 California Manual of Uniform Traffic Control Devices 2014 (revised March 30, 2021)  Design and Access Management Guidelines for Truck Routes: Planning and Design (2020) City of Wildomar, California Municipal Code (as of 4/12/2023) – This document contains two sections relevant to trucking activities on City roads: Regulations of Oversize and Overweight Vehicles (Title 10), and regulations of noise in the City (Title 9). Oversize and Overweight Vehicles are a subset of the trucking population that would utilize truck routes. 10.08.010 establishes that oversize and overweight vehicles require permits to move a load “along or across any City road.”

10.08.080 establishes that the Road Commissioner shall prepare regulations for the purpose of protecting the public, road surfaces, and overhead utilities “within a City road or adjacent thereto,” as well as protecting private and public property, that repairs be made by the permittee for any damages, and that fees be collected. 10.08.110 requires permittee to protect road facilities to the satisfaction of their owners and at permittee’s expense.

Public Peace and Welfare Chapter 9.48 Noise Regulation establishes maximum decibel levels for the times 7:00am – 10:00pm (daytime), and 10:00pm – 7:00am (overnight). The City’s noise ordinance focuses on sounds coming from properties. Maximum daytime decibels depend on the General Plan foundation component (community developments of various densities, as well as rural settings), and range from 55 to 75 decibels. The community developments with the highest permitted decibel E-172
C R
1948
Wildomar GPU Page 3
Goods Movement Memorandum
levels are light and heavy industrial areas, while the lowest maximums are for residential areas.

Typically, overnight decibels levels are between 10 and 20 decibels less than daytime levels.

However, “Sound emanating from. . . motor vehicles” is exempt from the City’s noise ordinance (with the exceptions of off-highway vehicles and motor vehicle sound systems).

City of Wildomar, California Pavement Management Plan – This document establishes processes for the maintenance of the City’s transportation system. It is a multi-year work plan that contains methods for guiding the determination of maintenance priorities, and in relation to funding availabilities.

City of Wildomar, California Pavement Management Report (2019) – This document presents a “Pavement Condition Index” (PCI), which supplies the framework for evaluating the condition of road surfaces in the City (and is used throughout the state of California). A new road surface would score 100 on the PCI, while a failed road surface would score 15 or less. The City of Wildomar’s average PCI is 68, which is slightly higher than the State’s average of 65. The City and all of Riverside County share an average PCI score of 68. This scoring suggests an overall need for “preventative maintenance” that pavement surfaces are “in need of surface sealing or thin overlay.” This document also assesses the condition of particular streets throughout the City of Wildomar and presents that data graphically in the form of useful maps. The document also presents five-year budget scenario plans that identify the prioritization of street treatments.

City of Wildomar, California Pavement Management Program Update (2021) – This document presents an update to the 2019 Pavement Management Report and supplies new pavement condition assessments (as of November 2021), as well as five-year budget scenarios plans identifying the prioritization of street treatments.

California Vehicle Code (website accessed 4/15/2023 and 4/17/2023) – The California Vehicle Code (CVC) provides the following 3-Step Guide for determining routes a truck may legally use are:

Step 1: Determining the truck category -- “Green” Surface Transportation Assistance Act (STAA) trucks, and “Black” California Legal trucks. There are two categories of truck tractor-semitrailers in California: (1) “Green” trucks, which are Interstate “STAA” (Surface Transportation Assistance Act) trucks; and (2) “Black” California Legal trucks. Maximum lengths of the trucks and their trailers are specified.

Step 2: Determine the state routes one can use. The Guide states the “California Truck Network Map” for State highways is the official government source for truck route information.

Step 3: Determine the local roads one can use based on destination, local terminal access and truck route maps, local truck routes, local terminal access routes, local contacts, and signs. About Local Truck Routes, the CVC states “Most cities and counties allow only the "black" California Legal trucks, and only on certain "truck routes" which are posted with "truck route" signs.” The CVC also presents California Truck Network Map and a District 8 Map. The CVC also specifies Special Route Restrictions. Two route restrictions are within District 8; both are in Upland, California.

E-173
C R
1949
Wildomar GPU Page 4
Goods Movement Memorandum
Finally, the CVC discusses the legal basis for truck restrictions. The CVC notes that “most truck ban requests arise from noise complaints.” However, given the fact that “overland trucking is a primary means for moving goods in the United States” and that “commerce and trade have state and federal legal protection,” truck bans require “substantial supporting evidence such as accident data and a reasonable alternate route.” The same conclusion is presented in the CVC’s discussion of “Peakhour Truck Restrictions.” California Manual of Uniform Traffic Control Devices 2014 (revised March 10, 2023) – This document (hereafter CAMUTCD) contains seven sections (six specifying signage, one specifying a plaque) related to trucks. They are:
 Section 2b.61 Truck Route Signs (and related)
 Section 2c.49 Truck Crossing Warning Sign
 Section 2d.16 Alternative Route Signs including Truck Routes o Section 2d.16 Auxiliary Signs for Alternative Routes (M4 Series) o Section 2d.20 Truck Auxiliary Sign
 Section 2I.03 General Service Signs for Freeways and Expressways  Section 6f.36 Motorized Traffic Signs
 Section 2B.13 Speed Limit Sign (R2-1)
 Section 2B.14 Truck Speed Limit Plaque (R2-2P)
Of these CAMUTCD regulations, the first, Truck Route Signs (and related), warrants specific mention.

It states that Caltrans is not unilaterally authorized to prohibit truck travel on State highways, that local ordinances cannot apply to State highways, and that any local ordinance restricting or banning trucks must supply an unrestricted alternate route.

Design and Access Management Guidelines for Truck Routes: Planning and Design (2020) (National Cooperative Highway Research Program) – This guide (hereafter “Guide”) presents “a broad ranges of issues related to access management and design for truck routes and site layout” (Foreword). The Guide’s intended readers are planners and engineers in transportation agencies and consulting firms.

The Guide addresses truck route access and design through four chapters (plus an introduction).

These chapters cover: Truck Operational Challenges and Needs, Truck Routes, Geometric Design and Access Management, and Balancing Truck Considerations with Other Modes. Issues addressed include land use and zoning impacts on truck movement, strategies for goods movement, assessment of benefit-cost differentials for accommodation of trucks, guidelines and strategies for truck routes and networks, and design and operations policies and practices.

The Guide provides guidelines on the following aspects of truck routes design and implementation:
 Defining a truck route as routes that carry ‘a substantial number of trucks”  Design of roadways intended to serve as truck routes including storage lengths, bridge clearances, and truck turning movements.

E-174
C R
1950
Wildomar GPU Page 5
Goods Movement Memorandum
 Limiting truck routes through residential areas whenever possible  Other topics discussed in the Guide include enforcement, violations, weigh stations, roadway maintenance, permits, and routing considerations (such as bridges (and their weight limits), overhead structures, cross-section widths, overhead traffic signals, roundabouts, route continuity, intersection design, and truck parking (including loading zones).  The final chapter of the Guide discusses the interaction between trucks and other modes, with the focus on pedestrians, bicyclists, and transit users.

Data Collection
Vehicle classification traffic counts were conducted at the thirteen (13) locations throughout the City.

Data was collected between May 19th and May 25th, 2023 except for Bundy Canyon Road between Monte Vista Drive and Oak Canyon Drive. Data for this segment was partially collected during the aforementioned dates and partially between July 22nd and July 25th due to rupture of the equipment3.

The new data was analyzed and compared to the May 2023 data as well as 2019 data. The results of this validation effort concluded that the traffic counts were deemed appropriate as there was a difference of roughly 4 percent. Full traffic count data can be provided on request by City staff.

Classification counts were collected at the following locations:
 Bundy Canyon Road between Mission Trail and I–15 SB Ramps  Bundy Canyon Road between I-15 NB Ramps and Monte Vista Drive  Bundy Canyon Road between Monte Vista Drive and Oak Canyon Drive  Bundy Canyon Road east of Oak Canyon Drive
 Clinton Keith Road between Palomar Street and I-15 SB Ramps  Clinton Keith Road between I-15 NB Ramps and Wildomar Trail  Corydon Road between Grand Avenue and Mission Trail
 Grand Avenue between Wildomar Trail and Corydon Road
 Mission Trail between Corydon Road and City Limits
 Palomar Street between Mission Trail and Clinton Keith Road  Palomar Street south of Clinton Keith Road
 Prielipp Road between Inland Valley Drive and Jackson Avenue  Wildomar Trail between Palomar Street and I-15 SB Ramps 3 This occurrence is not uncommon as the equipment used can be fragile (pneumatic tubes made of polyurethane).

Safety
Collision data can be used to identify potential deficiencies or safety issues related to vehicular travel. The collision review draws from five years of data (2018-2023) obtained from the SWITRS.

Additionally, data from the city’s Crossroads database was included in the analysis. For the purpose of determining goods movement routes, only collisions involving heavy vehicles were examined.

Figure 3 displays locations of collisions involving heavy vehicles. As shown, this type of collision has primarily occurred on Bundy Canyon Road and Mission Trail over the past five years.

Table 3 shows the top corridors in terms of number of heavy vehicle collisions.

This may be due to the lack of friction elements (i.e., sidewalks, bike lanes, medians, on-street parking, etc.) along the roadway which tends to give drivers an “open road” feeling, hence, creating an environment for speeding. Additionally, a significant portion of Bundy Canyon Road heading westbound is on a downgrade and could also contribute to unsafe speeds.

Bundy Canyon Road is identified as a 6-Lane Primary Arterial roadway with a Raised Median in the City of Wildomar Mobility Element (2021). Additionally, sidewalks and a Class I multi-use path are planned along Bundy Canyon Road which will add friction elements to the roadway and accompanied with appropriate signage and striping, should create an environment prone to less speeding occurrences.

Currently, Bundy Canyon Road has been widened and improved from Cherry St to approximately 1600’ east of Oak Canyon Drive from a 2-Lane roadway to a 4-Lane roadway with turn lanes where the bike lanes will be connected to a planned Class 1 pedestrian/bike trail, as part of the Bundy Canyon Road Improvement Project, Segment 1 (CIP 026-1).

Adjacent Cities
An important aspect of planning for goods movement routes is not only to ensure connectivity within Wildomar but also with other cities in the region. Therefore, the goods movement routes for the neighboring cities of Lake Elsinore, Murrieta and Menifee were also taken into consideration to ensure that any recommendations of potential Wildomar goods movement routes were consistent E-184
C R
1960
Wildomar GPU Page 15
Goods Movement Memorandum
with currently existing routes. Currently, Mission Trail is designated as a goods movement route by the City of Lake Elsinore and the same is true about Bundy Canyon Road in the City of Menifee (in the City of Menifee Bundy Canyon Road changes to Scott Road). Truck routes for the surrounding cities can be found in Attachment A.

Summary
The proposed goods movement routes were developed based on a variety of factors including collected data, the calculated truck volume percentages, a desire for connectivity within the region, surrounding cities truck routes, and a desire to increase roadway safety. Once implemented, these routes will allow for the consolidation and increased efficiency of goods movement throughout the city.

Figure 4 displays the recommended goods movement routes within the City of Wildomar, proposed land uses, as well as truck routes from adjacent cities. While currently both Wildomar Trail and Clinton Keith Road do not currently have significant heavy vehicle traffic both were included in the recommendation because of their connectivity (both to nearby cities as well as regional networks) and their anticipated future cross sections. Based on preferred future land uses these roadways are also anticipated to be adjacent to industrial, retail, and construction land uses.

It is important to note that a roadway not being designated a goods movement route does not mean that trucks or other heavy vehicles making deliveries/pick-ups to specific locations on a roadway are prohibited as that would be in violation of the California Vehicle Code. However, cut-through or passthrough traffic from trucks or other heavy vehicles would be prohibited along the proposed routes.

These recommendations (Figure 4) are consistent with the City of Wildomar Municipal Code section

10.20.150 subsection C regarding commercial vehicles.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-1

1. INTRODUCTION

PURPOSE, SCOPE, AND CONTENT
The Safety Element conveys the City of Wildomar’s (City’s) goals, policies, and actions to minimize the hazards to safety in and around Wildomar. This Safety Element will replace the 2003 County/City Safety Element upon adoption. It identifies the natural and human-caused hazards that affect existing and future development and provides guidelines for protecting residents, employees, visitors, and other community members from injury and death. It describes present and expected future conditions and sets policies and standards for improved public safety. The Safety Element also seeks to minimize physical harm to the buildings and infrastructure in and around Wildomar to reduce damage to local economic systems, community services, and ecosystems.

Some degree of risk is inevitable because the potential for many disasters cannot be completely eliminated and the ability to predict such disasters is limited. The goal of the Safety Element is to reduce the risk of injury, death, property loss, and other hardships to acceptable levels. One of the fundamental values of the Vision for Wildomar, as adopted by the City Council on April 12, 2017 (via Resolution No. 2017-12), highlights the importance of safety to the people of Wildomar:
“The City of Wildomar will be a safe and active community with responsible growth and quality infrastructure while keeping a hometown feel.”
This “value” underlies the policy direction of the Safety Element and is further defined by the following Vision statement:
“Considerable protection from natural hazards such as earthquakes, fire, flooding, slope failure, and other hazardous conditions is now built into the pattern of development authorized by the General Plan.”
Based on the direction provided by the Vision, and in compliance with state law, the primary objective of the Safety Element is to “reduce death, injuries, property damage, and economic and social impact from hazards.” The Safety Element serves the following functions:
• Develops a framework by which safety considerations are introduced into the land use planning process.

c======================-=-=-=- 1977

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-2 • Facilitates the identification and mitigation of hazards for new development, and thus strengthens existing codes, project review, and permitting processes. • Presents policies directed at identifying and reducing hazards in existing development. • Strengthens earthquake, flood, inundation, and wildland fire preparedness planning and post-disaster reconstruction policies.
• Identifies how hazards are likely to increase in frequency and intensity in the future and provides policies to increase community resilience.

REGULATORY FRAMEWORK
Under state law, all counties and incorporated communities in California must prepare a General Plan, which must address several topics, one of which is public health and safety. The Safety Element addresses this topic in accordance with state requirements, which are laid out in California law, particularly Section 65302(g) of the California Government Code. State law requires that the Safety Element address the following:
• Protect the community from risks associated with a variety of hazards, including seismic activity, landslides, flooding, and wildfire, as required by the California Government Code Section 65302(g)(1). • Map and assess the risk associated with flood hazards, develop policies to minimize the flood risk to new development and essential public facilities, and establish effective working relationships among agencies with flood protection responsibilities, as required by California Government Code Section 65302(g)(2).
• Map and assess the risk associated with wildfire hazards, develop policies to reduce the wildfire risk to new land uses and essential facilities, ensure there is adequate road and water infrastructure to respond to wildfire emergencies, and establish cooperative relationships between wildfire protection agencies, as required by California Government Code Section 65302(g)(3). • Assess the risks associated with climate change on local assets, populations, and resources. Note existing and planned development in at-risk areas and identify agencies responsible for providing public health and safety and environmental protection. Develop goals, policies, and objectives to reduce the risks associated with climate change impacts, including locating new public facilities outside of at-risk areas, providing adequate infrastructure in at-risk areas, and supporting natural infrastructure for climate adaptation, as required by California Government Code Section 65302(g)(4). c======================-=-=-=
F-6
- 1978

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-3 • Identify residential developments in any hazard area identified that do not have at least two emergency evacuation routes, as required by California Government Code Section 65302(g)(5).

RELATIONSHIP TO OTHER DOCUMENTS
The Wildomar Safety Element does not exist in a vacuum but is instead one of several plans that address public safety and related topics. The Safety Element must be consistent with these other plans to minimize conflicts between documents and ensure that the City has a unified strategy to address public safety issues. The Safety Element incorporates information, technical analyses, and policies from these other documents where appropriate to help support this consistency.

OTHER GENERAL PLAN ELEMENTS
The Safety Element is one of several elements of the Wildomar General Plan. Other social, economic, political, and aesthetic factors must be considered and balanced with safety needs. Rather than compete with the policies of related elements, the Safety Element provides policy direction and designs safety improvements that complement the intent and policies of other General Plan elements. Crucial relationships exist between the Safety Element and the other General Plan elements. How land uses are determined in areas prone to natural hazards, what regulations limit development in these areas, and how hazards are mitigated for existing development, are all issues that tie the elements together. For instance, Land Use Element diagrams and policies must consider the potential for various hazards identified in the Safety Element and must be consistent with the policies to address those hazards. The Multipurpose Open Space Element is also closely tied to the Safety Element. Floodplains, for example, are not only hazard areas, but often serve as sensitive habitat for threatened or endangered species or provide recreation or passive open space opportunities for residents and visitors. As such, flood and inundation policies balance the need to protect public health and safety with the need to protect habitat and open space. Safety Element policies, especially those concerning evacuation routes and critical facilities, must also be consistent with those of the Circulation Element. The City’s Circulation Plan routes are considered the backbone routes for evacuation purposes. Policies and information in this Safety Element should not conflict with those in other elements.

CITY OF WILDOMAR LOCAL HAZARD MITIGATION PLAN
The City of Wildomar’s Local Hazard Mitigation Plan (LHMP) is a plan to identify and profile hazard conditions, analyze risk to people and facilities, and develop mitigation actions to reduce or eliminate hazard risks in Wildomar. The City prepared the LHMP in accordance with the federal Disaster Mitigation Act of 2000 c======================-=-=-=
F-7
- 1979

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-4 and the Federal Emergency Management Agency’s (FEMA’s) LHMP guidance. The mitigation actions in the LHMP include both short-term and long-term strategies, and involve planning, policy changes, programs, projects, and other activities. The LHMP and Safety Element address similar issues, but the Safety Element provides a higher-level framework and set of policies, while the LHMP focuses on more specific mitigation, often short-term, actions. The LHMP, as its name implies, focuses on mitigation-related actions, while the Safety Element also includes policies related to emergency response, recovery, and preparation activities. The current LHMP, as certified by FEMA, is incorporated into this Safety Element by reference, as permitted by California Government Code Section 65302.6. It is available online at: https://www.cityofwildomar.org/314/LocalHazard-Mitigation-Plan.

RELATIONSHIP TO THE EMERGENCY MANAGEMENT DEPARTMENT
The County of Riverside Emergency Management Department (EMD) is responsible for providing emergency management services. EMD has four divisions that combine traditional emergency management, public health disaster management, and emergency medical services into a single, comprehensive, all hazards department.

EMD works with local cities such as Wildomar, fire and law enforcement agencies, and special districts to support and implement emergency mitigation and preparation activities across Riverside County, secure resources for first responders, and coordinate with state and federal emergency agencies. EMD’s emergency preparation and response activities, including many of the Safety Element policies implemented by the City in coordination with EMD, are laid out in this Safety Element.

HAZARD REDUCTION
Hazard-reduction programs are designed to improve the safety of existing development. For example, older structures, built to superseded code standards, may need seismic upgrading. Owners of older structures may voluntarily upgrade, be strongly incentivized to upgrade, or be required to do so. Additional examples of hazardreduction programs include:
• Strengthening pipelines and developing emergency back-up capability by public utilities serving the City of Wildomar;
• Collaborating with water purveyors to ensure adequate fire flow during emergencies; • Creating defensible space around buildings to prevent damage from wildfires; c======================-=-=-=
F-8
- 1980

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-5 • Planning for emergency response at the government and individual level to reduce the risk to the public from hazards; and
• Identifying unsafe structures and posting public notices.

To reduce hazards in areas mapped as hazard zones, the City of Wildomar uses a combination of methods:
• Special investigation and reporting requirements;
• Land use planning;
• Real-estate disclosure;
• Incentives to encourage hazard mitigation;
• Public education; and
• Disincentives, including fines and fees for those who choose to take the risk of that hazard.

VULNERABLE COMMUNITIES
Due to financial limitations, mobility challenges, and lack of access to medical care, the most vulnerable populations to environmental pollution and other hazards include households in poverty, seniors living alone, outdoor workers, and persons experiencing homelessness. Based on the CalEnviroScreen 3.0 model, which uses pollution and population characteristic indicators to assess pollution burden within communities, overall pollution burden is relatively low.
1 However, there are communities that may be disproportionately impacted by pollution and hazards.

Low-income communities in Wildomar provide an effective lens for assessing where pollution and hazards may disproportionately be affecting vulnerable communities. Therefore, this Safety Element defines vulnerable communities as low-income areas that are disproportionately affected by environmental pollution and other hazards that can lead to negative health effects. A low-income area is defined as an area with household incomes at or below 80 percent of the statewide median income or with household incomes at or below the threshold 1 California Office of Environmental Health Hazard Assessment. 2018. CalEnviroScreen 3.0. https://oehha.ca.gov/calenviroscreen/report/calenviroscreen-30. c======================-=-=-=
F-9
- 1981

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-6 designated as low income by the Department of Housing and Community Development’s list of state income limits, which is approximately $59,993 in Wildomar.

Vulnerable communities in Wildomar are particularly affected by pollution and hazards in the northwest region of the city, along Corydon Road and Mission Trail. Vulnerable communities are often affected first and at greater levels by pollution and climate-related impacts. These communities are burdened with poorer air quality and pollution and face a higher risk of flood and wildfire hazards. More specifically, air quality impacts are associated with elevated concentration levels of diesel particulate, ozone, and particulate matter 2.5 (PM2.5).

Although flood risk is present, the 100- and 500-year flood zone is limited to areas along the city boundary, near Corydon Road and Mission Trail. To the east of Interstate 15 (I-15), vulnerable communities are within a very high wildfire hazard severity zone.

Some hazards, such as toxins or traffic hazards, may be dangerous enough to harm human health in isolation.

However, some hazards may not be harmful to health by themselves, but become harmful when combined with other health risks to a community. This is a compounded health risk, often referred to as cumulative risk. Today, people are often exposed to multiple health risks, such as ozone and particulate matter, while concurrently living in unhealthy housing conditions and/or experiencing poverty and other socioeconomic stressors that are associated with negative health outcomes. These conditions are experienced more often by vulnerable communities.
“Environmental justice” is defined in California law as the fair treatment of people of all races, cultures, and incomes with respect to the development, adoption, implementation, and enforcement of environmental laws, regulations, and policies. “Environmental justice” includes, but is not limited to, all of the following:
• The availability of a healthy environment for all people. • The deterrence, reduction, and elimination of pollution burdens for populations and communities experiencing the adverse effects of that pollution, so that the effects of the pollution are not disproportionately borne by those populations and communities. • Governmental entities engaging and providing technical assistance to populations and communities most impacted by pollution to promote their meaningful participation in all phases of the environmental and land use decision-making process.
• At a minimum, the meaningful consideration of recommendations from populations and communities most impacted by pollution into environmental and land use decisions. c======================-=-=-=

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-8 Environmental justice in the community can be implemented in various ways, such as through policies and actions that improve sustainability and resilience, protect community health, and prioritize safety. This Safety Element identifies where vulnerable communities experience existing and likely future hazardous conditions and other public safety issues in Wildomar and incorporates environmental justice into its policies and actions to address specific hazards for vulnerable communities in Wildomar. These policies and actions aim to reduce the unique or compounded health risks.

CLIMATE CHANGE VULNERABILITY
Changes to the global climate system are expected to affect future occurrences of natural hazards in and around Wildomar. Many hazards are projected to become more frequent and more intense in coming years and decades, and in some cases, these trends have already begun. According to California’s Fourth Climate Change Assessment,2 Wildomar can expect the following changes to climate-related hazard events:
• Both droughts and floods are expected to become more frequent as precipitation is expected to occur in fewer, more intense storms due to climate change. Although Wildomar is likely to experience little change in overall precipitation levels from climate change, the region is also expected to see an increase in the number of extreme precipitation events. As a result, floods are expected to occur more often in Wildomar, and climate change may expand the parts of the city that are considered flood-prone. Climate change is expected to increase the frequency and severity of droughts that cause soil to dry out and condense. When precipitation does return, more water runs off the surface rather than being absorbed into the ground, which can lead to floods.
• Warmer temperatures are projected to cause an increase in extreme heat events. Because extreme heat is relative to the area, this means that extreme heat events may occur anywhere in Riverside County. The number of extreme heat days, defined in Wildomar as a day when the high temperature is at least 105 degrees Fahrenheit (°F), is expected to rise from a historical annual average of 4 to between 25 and 37 by the middle of the century (2041 to 2060), and to between 34 and 58 by the end of the century (2070 to 2099). In addition to the increases in extreme heat events, Wildomar is expected to see an increase in the average daily high temperatures. Extreme heat poses a significant human health risk, especially to senior citizens, outdoor workers, and persons who do not have access to adequate cooling, including 2 Bedsworth, Louise, Dan Cayan, Guido Franco, Leah Fisher, Sonya Ziaja.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-9 people experiencing homelessness. Some buildings and infrastructure systems may be damaged by very high temperatures, constraining their ability to meet community needs. • Climate change can increase the rates of infection for various diseases because many of the animals that carry diseases are more active during warmer weather. There are a number of diseases that are linked to climate change and can be harmful to the health of Wildomar community members, such as hantavirus pulmonary syndrome, Lyme disease, West Nile fever, and influenza. Many of these diseases are carried by animals, such as mice and rats, ticks, and mosquitos, which are usually seen as pests even if they do not cause infections. Warmer temperatures earlier in the spring and later in the winter can cause these animals to be active for longer periods, increasing the time that these diseases can be transmitted. • Wildomar is expected to see an increase in wildfires due to hotter, drier weather. Although the risk is greatest in the forested areas of western Riverside County along the San Jacinto Mountains, Wildomar may still experience an increase in wildfire activity. More frequent regional wildfires may also create poor air quality. Wildfire activity across Riverside County is expected to increase approximately 16 percent above historic levels by the middle of the century. • Severe weather events, such as strong storms and high winds, may become more frequent and intense due to climate change. Climate change is expected to cause an increase in intense rainfall, which is usually associated with strong storm systems. Heavy rainfall may also contribute to an increased risk of landslides in the hills around Wildomar. In western Riverside County, most severe weather is linked to high winds. The types of dangers posed by severe weather vary widely and include injuries or deaths, damage to buildings and structures, fallen trees, roads blocked by debris, and fires sparked by lightning.

VULNERABILITY ASSESSMENT RESULTS
Under California law, the Safety Element is required to include a vulnerability assessment that looks at how people, buildings, infrastructure, and other key community assets may be affected by climate change. The City conducted a Climate Change Vulnerability Assessment in spring of 2021, to analyze Wildomar’s susceptibility to climate-related hazards. The City of Wildomar’s vulnerability assessment, prepared in accordance with the most recent available guidance in the California Adaptation Planning Guide, assesses how eight different climate-related hazards (air quality, drought, extreme heat, flooding, human health hazards, landslides, severe weather, and wildfire) may affect 56 different population groups and community assets. Each population or asset received a score of V1 (minimal vulnerability) to V5 (severe vulnerability) for each climate-related hazard.

The Climate Change Vulnerability Assessment indicates that Wildomar’s populations and assets are most vulnerable to wildfires, extreme heat, severe weather, and drought. c======================-=-=-=

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-10 Populations in Wildomar tend to be vulnerable to extreme heat, human health hazards, and wildfire, which directly affect health outcomes. As discussed previously, the most vulnerable communities include households in poverty, seniors living alone, outdoor workers, and persons experiencing homelessness. Vulnerable populations, especially those located on single-access roads, are also highly vulnerable to hazards, such as landslides, severe weather, flooding, and wildfire.

Citywide, energy delivery is vulnerable to multiple hazards, including severe weather, such as high winds that can trigger public safety power shutoff (PSPS) events, extreme heat that reduces the capacity and strains the system, and wildfires that damage the system, ultimately disrupting energy service. These conditions can damage communication infrastructure, decreasing network capacity. There may be a higher demand for communication services during severe weather, potentially putting stress on the network and increasing the risk of service interruptions. Furthermore, energy delivery services, specifically electricity delivery, is subject to harm during extreme heat events. Extreme heat can lead to power outages by causing mechanical failure of grid equipment, heat damage to power lines, and by creating a high demand for electricity to power air conditioners, all of which place stress on the network. This is likely to lead to greater service disruptions.

An increase in droughts, extreme heat, and wildfire create higher vulnerabilities for chaparral, woodland, and grassland habitat. Drought and extreme heat can stress vegetation, weakening or killing a variety of native species and habitats. Although chaparral, woodland, and grassland in the region are adapted to infrequent, lowintensity wildfire, many native species are still vulnerable to large and intense wildfire events. Moreover, grasslands pose an extreme risk due to their high, easily ignitable fuel loads and the invasion of non-native species has greatly increased the risk of severe wildfire events. Pests, such as shot hole borers, have increased due to drought and higher temperatures that impact tree health and make them more vulnerable to pests. Such pests can decimate woodland habitats and these species may not be able to recover. This can in turn affect local economic activities in Wildomar, such as outdoor recreation activities and commercial activity from visitors that travel through the city to get to state and national parks and forests.

PSPS events can also create vulnerabilities for Wildomar community members. The vast majority of homes and businesses do not have backup power supplies, so a loss of electricity can cause a loss of refrigeration for food and medical supplies, limit cooking, cause loss of heating or cooling (particularly dangerous during extreme heat or cold events), lighting, and limited or no access to the Internet or other information systems. Many businesses are forced to close during a PSPS, causing economic hardships and depriving community members of important services, such as grocery stores, gas stations, and banks/ATMs. PSPS events may also be harmful to people who depend on electrically powered medical devices. Some property owners have purchased backup power generators, although these produce high levels of noise, pollution, and odors. c======================-=-=-=

Wildomar Safety Element – Adopted October 13, 2021 SE-12 vulnerability assessment prepared for western Riverside County as part of the Resilient IE project. This Vulnerability Assessment refines the findings from Resilient IE to focus on the City of Wildomar, thus more accurately reflecting the conditions and characteristics unique to Wildomar.

The Vulnerability Assessment considers the threats from all relevant climate-related hazards, which are events or physical conditions that have the potential to cause harm or loss and emphasizes changes to hazard frequency and severity due to climate change. The Vulnerability Assessment also assesses populations or assets facing potential harm from the hazards. This includes the risk of physical damage to buildings and infrastructure, social vulnerability of persons likely to be disproportionately harmed by hazards, potential disruption to the City’s economic engines, loss of important services, and damage to sensitive ecosystems. The results of the Vulnerability Assessment are integrated into the hazards and other public safety issues previously mentioned.

A full list of the Vulnerability Assessment results is also provided in Appendix A.

CODE CONFORMANCE AND DEVELOPMENT REGULATIONS
The City of Wildomar Department of Building and Safety provides technical expertise in reviewing and enforcing the City Building and Fire Codes. These codes establish site-specific investigation requirements, construction standards, and inspection procedures to ensure that development does not pose a threat to the health, safety, and welfare of the public. Every three years, the City’s Building and Fire Codes are adopted from the California Building and Fire Codes. These codes contain baseline minimum standards to guard against unsafe development.

At a minimum, it is imperative to enforce the most recently adopted regulatory codes for new development and significant redevelopment, including the City’s Zoning Ordinance and Land Use Ordinance (e.g., WaterEfficient Landscape Ordinance), which support the California Building and Fire Codes. The California Environmental Quality Act (CEQA) adds another level of safety review, requiring that environmental constraints be considered prior to approval of development projects. Additional guidelines and standards are introduced through the Safety Element. Special development regulations can reinforce and augment existing code standards by raising the level of hazard-conscious project design and mitigation engineering. Examples include additional geologic/geotechnical investigation and additional reinforcement of foundations in areas of potential ground failure.

While foundation investigations are required by the City of Wildomar’s Building Code, it is important to emphasize expected levels of investigation and protection. Furthermore, some requirements may only apply to critical facilities, such as detailed seismic analyses, could be expanded to include other structures and lifelines. c======================-=-=-=

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-13 Where engineering methods cannot mitigate the hazards, avoidance of the hazard is appropriate, such as where ground rupture along active or potentially active fault traces are identified during project investigation. Special minimum setbacks away from active faults, which are already required for critical facilities, can also be defined for other structures and lifelines.

GOAL S-1: To provide development regulations consistent with State of California requirements and best practices.

POLICY S-1 Enforce state laws aimed at identification, inventory, and retrofit of existing vulnerable structures and mitigate hazard impacts through adoption and strict enforcement of current building codes, which will be amended as necessary when local deficiencies are identified.

POLICY S-2 Continue to enforce penalties against grading without permits and ensure the restoration of land damaged or degraded from grading activities. Continue to educate the public about the benefits of grading with permits and the penalties for grading without them. If the penalties are determined to be ineffective, explore whether levying greater penalties would be more effective in deterring illegal grading and ensuring proper restoration of damaged lands.

POLICY S-3 Incorporate the current City of Wildomar Local Hazard Mitigation Plan, as adopted by the Federal Emergency Management Agency, into this Safety Element by reference, as permitted by California Government Code Section 65302.6.

POLICY S-4 Require structural and non-structural assessment and, when necessary, mitigation of other types of potentially hazardous buildings that:
(1) Are undergoing substantial repair or improvements resulting in more than half of the assessed property value, or
(2) Are considered an element of blight in a redevelopment district. Potential implementation measures may include:

Use of variances, tax rebates, fee waivers, credits, or public recognition as incentives.

SEISMIC AND GEOLOGIC HAZARDS
Seismic and geologic hazards are risks caused by the movement of different parts of the Earth’s crust, or surface.

Seismic hazards include earthquakes and hazardous events caused by them. Geologic hazards are other hazards involving land movements that are not linked to seismic activity and are capable of inflicting harm to people or property.

SEISMIC HAZARDS
Seismic activity occurs along boundaries in the Earth’s crust, called faults. Pressure along the faults build over time and is ultimately released, resulting in ground shaking that we refer to as an earthquake. Earthquakes can also trigger other hazards, including surface rupture (cracks in the ground surface), liquefaction (causing loose soil to lose its strength), landslides, and subsidence (sinking of the ground surface). Earthquakes and other seismic hazards often damage or destroy property and public infrastructure, and falling objects or structures pose a risk of injury or death.

While Wildomar is at risk from many natural and human-caused hazards, the event with the greatest potential for loss of life or property and economic damage is an earthquake. This is true for most of Southern California, since damaging earthquakes affect widespread areas, trigger many secondary effects that can overwhelm the ability of local jurisdictions to respond. In Wildomar, earthquake-triggered effects include ground shaking, fault rupture, landslides, liquefaction, subsidence, and seiches. Earthquakes can also cause human-caused hazards such as urban fires, dam failures, and toxic chemical releases.

Earthquake risk is very high in the western portion of Riverside County, including the City of Wildomar, due to the presence of two of California’s most active faults, the San Andreas and San Jacinto Faults. Most of the loss of life and injuries from earthquakes are due to damage and collapse of buildings and structures. Building codes for new construction have generally been made more stringent following damaging earthquakes. However, in F-18

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-15 Wildomar, structures built prior to the enactment of these improved building codes have generally not been upgraded to current standards and are vulnerable in earthquakes. Comprehensive hazard mitigation programs that include the identification and mapping of hazards, prudent planning and enforcement of building codes, and expedient retrofitting and rehabilitation of weak structures can significantly reduce the scope of an earthquake disaster.

Western Riverside County contains parts of several known active and potentially active earthquake faults, including the San Andreas Fault, San Jacinto Fault, and Elsinore Fault. The San Andreas Fault, the largest fault in California, runs from the Salton Sea north along the east side of the Coachella Valley, continuing north along the Transverse and Coast Ranges until running offshore in Mendocino County. The San Jacinto Fault runs from the Imperial Valley northwest through western Riverside County until it ends at the Cajon Pass. The Elsinore Fault zone extends from western Imperial County to the Chino Hills and runs along Riverside County’s western border with Orange County. Historically, the San Andreas Fault is the most active among the fault network that cuts through rocks of the California coastal region. The San Jacinto Fault has had a higher level of moderate to large earthquakes during the past 50 to 100 years, although the rate of slip is not as high. The main trace of the Elsinore Fault zone has only seen one historical event greater than magnitude 5.2 – the earthquake of 1910, a magnitude 6 near Temescal Valley. Wildomar has experienced several noticeable ground movement incidents over the past years, but no local damage was sustained. Active faults located in close proximity to the city or that can cause damage to the city, include the following:
• Elsinore Fault Zone: This fault zone, which includes the Wildomar and Wolf Valley Faults, passes through the city on the west side of I-15. The fault zone is capable of generating earthquakes ranging in magnitude between 6.5 and 7.5.
• Wildomar Fault: As depicted on Figure 1-0, this fault strand of the Elsinore Fault zone runs northwest/southeast and is located in the city approximately 2,000 to 4,000 feet west of I-15. The areas adjacent to the fault are within a “Special Studies Zone,” as designated under the Alquist-Priolo Special Study Zone Act of 1972.
• San Andreas Fault Zone: This fault zone, located approximately 50 miles northeast of the city, is the dominant active fault in California. The maximum credible earthquake from this fault zone is a magnitude 8.3.
• San Jacinto Fault Zone: This fault zone is located approximately 30 miles northeast of the city and has a maximum credible earthquake magnitude of 7.5.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-16 In addition to these active faults, two potentially active faults, the Agua Caliente Fault zone and the Murrieta Hot Springs Fault, are also located near the city. In the event of an earthquake, the location of the epicenter, as well as the time of day and season of the year, would have a profound effect on the number of deaths and casualties, as well as property damage. There are a number of small-scale earthquakes that happen weekly, but larger scale or catastrophe shaking is less likely. Property and human life in Wildomar are at risk for a significant earthquake causing catastrophic damage and strains on response and mitigation resources. The county experiences hundreds of minor quakes and tremblers each month from the myriad of faults in the area. Studies indicate that stress is building up in major faults like the San Andreas. A major quake could happen at any time.

The San Andreas, San Jacinto, and Elsinore Faults are all capable of producing significant earthquakes, with a magnitude of 6.7 or greater. Table S-1 shows the chances of a major earthquake on these three faults within Riverside County by 2045, according to the Third California Earthquake Rupture Forecast. Other faults, both in and outside Riverside County, may also be capable of generating significant earthquakes with damaging effects in the county.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-18 Portions of the city are susceptible to liquefaction, which is a potentially destructive secondary effect of strong seismic shaking. Liquefaction occurs primarily in saturated, loose, fine- to medium-grained soils in areas where the groundwater table is within approximately 50 feet of the surface. Shaking causes the soils to lose strength and behave as liquid. Excess water pressure is vented upward through fissures and soil cracks and can result in a water-soil slurry flowing onto the ground surface. Liquefaction-related effects include loss of bearing strength, ground oscillations, lateral spreading, and flow failures or slumping. Site-specific geotechnical studies are the only practical and reliable way of determining the specific liquefaction potential of a site; however, a determination of general risk potential can be provided based on soil type and depth of groundwater. The City has delineated areas of known and suspected liquefaction hazard. In general, liquefaction susceptibility ranges from very low in the former lake footprint to moderate on much of the remainder of the valley floor and very high in the valley floor corridor formerly occupied by the axial riverine drainage. Areas identified as susceptible to liquefaction are identified in Figure 2-0.

Areas are susceptible to liquefaction based on a combination of known factors in some areas and the absence of known factors in other areas. Additionally, these potential hazard zones are not an absolute indication that the hazard truly exists nor are they an indicator of the extent of damage that may or may not occur at a given site.

Research confirms there is a potential for liquefaction to occur; however, this research also confirms minimal liquefaction-induced ground settlement is anticipated to occur for the areas that were studied. In most cases, proper design and construction of subgrade soils and building foundations provides a mechanism to mitigate the risk of seismic hazards to an acceptable level in conformance with the California Building Code. The representation of areas having a liquefaction potential is only intended as notification to seek further site-specific information and analysis of this potential hazard as part of future site development. It should not be solely relied upon, without site-specific information and analysis, for design or decision-making purposes.

GEOLOGIC HAZARDS
Geologic hazards, such as landslides and erosion, depend on the geologic composition of the area. Landslides and rock falls may occur in sloped areas, especially areas with steep slopes, and usually in areas of loose and fragmented soil. Landslides, rockfalls, and debris flows occur continuously on all slopes; some processes act very slowly, while others occur very suddenly, often with disastrous results. They often occur as a consequence of seismic activity or heavy rainfall, either of which may cause slopes to lose structural integrity and slide. There are predictable relationships between local geology and landslides, rockfalls, and debris flows. Slope stability is dependent on many factors and interrelationships, including rock type, pore water pressure, slope steepness, and natural or human-made undercutting. Figure 3-0 shows the landslide risk in and around Wildomar.

Landslide risk is greatest south of Grand Avenue and throughout a majority of the land east of I-15, particularly along hillsides. Landslide susceptibility presents a significant risk to vulnerable communities as well. The highest threat for these communities occurs in the northern region of the city, north of Lemon Street and to the west and east of I-15.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-21 Expansive soils have a significant amount of clay particles that can give up water (shrink) or take on water (swell). The change in volume exerts stress on buildings and other loads placed on these soils. The occurrence of these soils is often associated with geologic units having marginal stability. Expansive soils can be widely dispersed and can be found in hillside areas as well as low-lying alluvial basins. Although expansive soils are now routinely alleviated through the City’s adopted Building Code, problems related to past, inadequate codes constantly appear. Expansive soils are not the only cause of structural distress in existing structures. Poor compaction and construction practices, settlement, and landslides can cause similar damage, but require different mediation efforts. Once expansion has been verified as the source of the problem, mitigation can be achieved through reinforcement of the existing foundation, or alternatively, through the excavation and removal of expansive soils in an affected area.

Hydroconsolidation, or soil collapse, typically occurs in recently deposited, Holocene (less than 10,000 years old) soils that were deposited in an arid or semi-arid environment. Soils prone to collapse are commonly associated with human-made fill, wind-laid sands and silts, and alluvial fan and mudflow sediments deposited during flash floods. When saturated, collapsible soils undergo a rearrangement of their grains, and the water removes the cohesive (or cementing) material. Rapid, substantial settlement results. In Wildomar, collapsible soils occur predominantly at the base of the mountains, where Holocene-age alluvial fan and wash sediments have been deposited during rapid runoff events. Typically, differential settlement of structures occurs when lawns or plantings are heavily irrigated in close proximity to the structure’s foundation. Forensic indications of collapsible soils include tilting or sagging floors, cracking or separating structures, and windows and doors that cannot open due to shifts in the building.

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as water or wind, causing the soil to deteriorate. Eroded topsoil can be transported into streams and other waterways. Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. The severity of water erosion is influenced by slope, soil type, soil water storage capacity, nature of the underlying rock, vegetation cover, and rainfall intensity and period. The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Wind erosion is a serious environmental problem attracting global attention. Soil movement is initiated as a result of wind forces exerted against the surface of the ground. Dust particles in the air create major health problems. Atmospheric dust causes respiratory discomfort, may carry pathogens that cause eye infections and skin disorders, and reduces highway and air traffic visibility. Dust storms can cause additional problems. Buildings, fences, roads, crops, trees, and shrubs can all be damaged by abrasive blowing soil.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-22 Slope instability can include deep-seated landslides, rockfalls, soil slumps, and debris flows. Without the presence of extensive flood-control devices, including large debris basins, areas with slope instability may be subject to debris flow inundation. Most often, debris flow inundation results in roadways and improvements blocked by boulders. Rarely do debris-flow-generating storms affect Wildomar. However, most areas with slope instability are within areas designated for open space or rural development.

Subsidence refers to the sudden sinking or gradual downward settling and compaction of soil and other surface material with little or no horizontal motion. It may be caused by a variety of human and natural activities, including earthquakes and water saturation. Areas identified as susceptible to subsidence are identified in Figure 3-0. Land subsidence and related issues have been well-documented in western Riverside County. Most of the early documented cases of subsidence affected only agricultural land or open space. As urban areas have expanded, so too have the impacts of subsidence on structures for human occupancy. Ground subsidence and associated fissuring in Wildomar have resulted from both falling and rising groundwater tables. In addition, many fissures have occurred along active faults that bound the San Jacinto Valley and Elsinore Trough.

Subsidence typically occurs throughout a susceptible valley. In addition, differential displacement and fissures occur at or near the valley margin and along faults. In western Riverside County, the worst damage to structures as a result of regional subsidence may be expected at the valley margins. Alluvial valley regions are especially susceptible. Figure 4-0 shows the subsidence zones in and around Wildomar. As illustrated in Figure 4-0, areas near Palomar Street, Corydon Road, and Bundy Canyon Road are within a subsidence zone. Notably, vulnerable communities in the city reside in this subsidence zone and are at risk to ground subsidence impacts. c======================-=-=-=

POTENTIAL CHANGES TO GEOLOGIC AND SEISMIC RISK IN FUTURE YEARS Likelihood of Future Occurrence
Seismic Risk
Earthquakes are likely to continue to occur on an occasional basis and are likely to be small. They may cause no substantive damage and may not even be felt by most people. Major earthquakes are rare, but a possibility in the region. No major earthquakes have been recorded with epicenters within the city, although the city has felt ground shaking from earthquakes with epicenters located elsewhere. Large earthquakes from faults such as the San Andreas Fault may cause significant damage to homes and businesses in the city. Based on historical data and the location of Wildomar relative to active and potentially active faults, the city will likely experience a significantly damaging earthquake in the next two decades.

If serious shaking does occur, newer construction is in general more earthquake resistant than older construction because of improved building codes. Manufactured housing is very susceptible to damage because the foundation systems are rarely braced for earthquake motions.

Geologic Risk
Minor landslides have occurred in the past, probably over the last several hundred years, as evidenced by both past deposits exposed in erosion gullies and recent landslide events. Western Riverside County has a history of landslides during seasons of high precipitation. With significant rainfall, additional failures are likely in landslide hazard areas and minor landslides will likely continue to impact the area when heavy precipitation occurs, as they have in the past. In addition, areas affected by recent fires show an increased landslide risk.

Climate Change and Geologic and Seismic Hazards
While climate change is unlikely to increase earthquake frequency or strength, the threats from seismic and geologic hazards are expected to continue. Climate change may result in precipitation extremes (i.e., wetter rainfall periods and drier dry periods). While total average annual rainfall may not change significantly, rainfall may be concentrated in more intense precipitation events. Heavy rainfall could cause an increase in the number of landslides or make landslides larger than normal. Increased wildfire frequency can destabilize hillsides due to loss of vegetation and change soil composition, which can contribute to greater runoff and erosion. The combination of a generally drier climate in the future, which will increase the chance of drought and wildfires, and the occasional extreme downpour, is likely to cause more mudslides and landslides. Impacts from these conditions would compound landslide potential for the most susceptible locations.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-25 GOAL S-2: To avoid the loss of life and injury and minimize property damage from seismic and related geological hazards.

Fault Rupture
POLICY S-5 Minimize fault rupture hazards through enforcement of Alquist-Priolo Earthquake Fault Zoning Act provisions and the following policies:
(1) Require geologic studies or analyses for critical structures, and lifeline, highoccupancy, schools, and high-risk structures, within 0.5 miles of all Quaternary to historic faults shown on the Earthquake Fault Studies Zones map. (2) Require geologic trenching studies within all designated Earthquake Fault Studies Zones, unless adequate evidence, as determined and accepted by the City of Wildomar Engineering Geologist, is presented. The City of Wildomar may require geologic trenching of non-zoned faults for especially critical or vulnerable structures or lifelines.
(3) Require that infrastructure systems, such as energy, communications, and transportation infrastructure, be designed to resist, without failure, their crossing of a fault, should fault rupture occur.
(4) Support efforts by the California Department of Conservation, California Geological Survey, to develop geologic and engineering solutions in areas of ground deformation due to faulting and seismic activity, in those areas where a fault cannot be reliably located.
(5) Encourage and support efforts by the geologic research community to better define the locations and risks of faults in and around the City of Wildomar. Such efforts could include data sharing and database development with regional entities, other local governments, private organizations, utility agencies or companies, and local universities.

POLICY S-6 Require automatic natural gas shutoff earthquake sensors in high-occupancy industrial and commercial facilities, as well as new homes, and encourage them for all existing residences.

POLICY S-8 Require that a state-licensed civil engineer investigate the potential for liquefaction in areas designated as underlain by “Susceptible Sediments” and/or “Shallow Groundwater” for all general construction projects and proposed critical facilities, except for accessory buildings.

POLICY S-9 Require that engineered slopes be designed to resist seismically-induced failure as appropriate. For lower-risk projects, this may include requiring slope design to be based on pseudo-static stability analyses using soil engineering parameters that are established on a site-specific basis. For higher-risk projects, appropriate standards may include requiring the stability analyses to factor in the intensity of expected ground-shaking.

FLOOD AND INUNDATION HAZARDS
Flooding is considered the rising and overflowing of a body of water onto normally dry land. History highlights floods as one of the most frequent natural hazards impacting communities in western Riverside County. Floods are among the costliest natural disasters in terms of human hardship and economic loss nationwide, causing substantial damage to structures, landscapes, and utilities, as well as life-safety issues. Flooding can be extremely dangerous, and even six inches of moving water can knock a person over given a strong current.

Floodwaters can transport large objects downstream, which can damage or remove stationary structures, such as dam spillways. Ground saturation can result in instability, collapse, or other damage. Objects can also be buried or destroyed through sediment deposition. Floodwaters can also break utility lines and interrupt services.

Standing water can cause damage to roads, foundations, and electrical circuits.

Floods are usually caused by large amounts of precipitation, either from a period of very intense precipitation or a long period of steady precipitation. Historically, Wildomar has been at risk of flooding primarily during the winter and spring months when stream systems swell with heavy rainfall. This type of flood results from prolonged, heavy rainfall and is characterized by high peak flows of moderate duration and by a large volume of runoff. Flooding is more severe when prior rainfall has resulted in saturated ground conditions. Flooding susceptibility in Wildomar is primarily associated with the Murrieta Creek as well as smaller-scale and flash flood events.

Flash flooding is a common problem for western Riverside County and typically associated with short-duration, high-intensity precipitation events often during summer thunderstorms. Such events can occur even during a drought. Localized flooding also occurs in Wildomar at various times throughout the year, especially in the western side of the city and along Murrieta Creek. These areas are primarily a result of little or no drainage infrastructure, undersized pipes where runoff exceeds pipe capacity even for minor storms, obstructions, or damaged drainpipes. The majority of the damaged lines are on the west side of the city, where there are limited storm drainpipes and some of the oldest infrastructure in the system.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-29 Historically, precipitation in and around Wildomar has been low to moderate. Precipitation occurs mainly in the fall, winter, and spring months, from November through April. Although Wildomar occasionally experiences periods of significant drought, the city can also experience periods of substantial rainfall. When Wildomar does experience heavy rain, or rain over a period of days or weeks, many areas of the city are subject to flooding.

Runoff from rain drains either naturally into creeks or flood-control facilities.

Both earthquake faults and developments reduce the total ground absorption area. Earthquake faults include bedrock features that create barriers to subsurface percolation, thus increasing the velocity and erosive capacity of stormwater runoff on hillsides. Development also creates impermeable surfaces (structures, pavement, streets). Stormwater runoff is augmented by water flows from development contributing to street flooding.

Moreover, developed areas generate irrigation water runoff from landscaping, which may channel stormwater and other runoff flows into nearby underdeveloped areas and street gutters. Areas at an elevated risk of flooding are generally divided into 100- and 500-year flood zones. A 100-year flood zone has a 1-percent chance of experiencing a major flood in any given year, a 200-year flood zone has a 0.5-percent chance of flooding in any given year, a 500-year flood zone has a 0.2-percent chance of flooding in any given year. Figure 5-0 shows the 100- and 500-year flood zones in and around Wildomar, as well as the flood hazard zones overlayed by vulnerable communities. The highest threat for these communities occurs in the northwestern region of the city, along Corydon Road and Mission Trail. A small portion of this community along Corydon Road is within the 500-year flood zone and to the north along Mission Trail, a small portion is within both the 100- and 500-year flood zone.

Agencies responsible for flood control in Wildomar include FEMA, the Federal Insurance Administration (FIA), and the Department of Water Resources (DWR).
• FEMA: FEMA manages the National Flood Insurance Program (NFIP), providing insurance to the public in communities that participate in the program. FEMA is the main federal government agency contact during natural disasters and publishes the Flood Insurance Rate Maps (FIRM), which identify the extent of flood potential in flood-prone communities based on a 100-year flood (or base flood) event. • FIA: The FIA is the primary agency that delineates potential flood hazard areas and floodways through the FIRMs and the Flood Boundary and Floodway Map. Flood insurance is required of all homeowners who have federally subsidized loans.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-32 Dam failure also poses a risk to the City of Wildomar. Dam break floods are usually associated with intense rainfall or prolonged flood conditions. A dam failure is an uncontrolled release of water from a reservoir through a dam as a result of structural failures or deficiencies in the dam. Dam failures can range from fairly minor to catastrophic and can potentially harm human life and property downstream from the failure. In addition, ecosystems and habitats are destroyed as a result of waters flooding them. Although dam failures are very rare, these events are not unprecedented. Additionally, the older that dams get, the more potential exists for catastrophic dam failures. There are four major causes of dam failures, which include the following:
• Overtopping: These failures occur as a result of poor spillway design, leading to a reservoir filling too high with water, especially in times of heavy rainfall. Other causes of this type of failure include settling of the crest of the dam or spillway blockage.
• Foundation defects: These failures occur as a result of settling in the foundation of the dam, instability of slopes surrounding the dam, uplift pressures, and seepage around the foundation. All of these failures result in structural instability and potential dam failure. • Piping and seepage failures: These failures occur as a result of internal erosion caused by seepage and erosion along hydraulic structures such as the spillways. As well, erosion as a result of animal burrows and cracks in the dam structure contribute to these failures. • Conduit and valve failure: These failures occur as a result of problems with valves and conduits.

Other dam failures arise as a result of other miscellaneous causes. Many dam failures are also the secondary result of other natural disasters, such as earthquakes, landslides, extreme storms, or heavy snow-melt. Other causes include equipment malfunction, structural damage, and sabotage.

In Wildomar, a major earthquake could cause a dam failure. Dams are constructed with safety features known as “spillways” that allow water to overtop the dam if the reservoir fills too quickly. Spillway overflow events, often referred to as “design failures,” result in increased discharges downstream and increased flooding potential. In a dam failure scenario, the greatest threat to life and property typically occurs in those areas immediately below the dam since flood depths and discharges generally decrease as the flood wave moves downstream. The primary danger associated with dam failure is the high-velocity flooding downstream of the dam and limited warning times for evacuation. The Diamond Valley Dam presents a downstream hazard to the City of Wildomar. Figure 6-0 identifies the areas at risk from dam failure. Dam failure risk extends from Mission Trail, in the northern portion of the city, to Grand Avenue, in the southern portion of the city. A majority of the area at risk is adjacent to Murrieta Creek. Dam failure presents a significant risk to vulnerable communities as F-36

POTENTIAL CHANGES TO FLOOD RISK IN FUTURE YEARS
Likelihood of Future Occurrence
Wildomar is traversed by Murrieta Creek and is at risk to both creek flooding and localized stormwater flooding.

Historically, Riverside County and the City of Wildomar have been subject to previous flooding events primarily during the winter and spring months when river systems swell with heavy rainfall runoff. Normally, stormwater is kept within defined limits by a variety of storm drainage and flood-control measures. Occasionally, extended heavy rains result in floodwaters that exceed normal high-water boundaries and cause damage. Flooding has occurred both within the 100- and 500-year floodplains and in other localized areas. As land uses and climate conditions shift and as improvements are made to flood-control channels, the size of these flood zones is likely to change.

In the City of Wildomar, much of the flood damage occurs in the floodplains of Murrieta Creek. Other problems connected with flooding and stormwater runoff include erosion, sedimentation, degradation of water quality, losses of environmental resources, and certain health hazards.

Climate Change and Flooding
Floods are among the most damaging natural hazards in Riverside County, and climate change is expected to make flood events worse. Although climate change may not change average precipitation levels significantly, scientists expect that it will cause more years with extreme precipitation events. This means that more years are likely to see particularly intense storm systems that drop enough precipitation over a short enough period to cause flooding. Although Southern California is likely to experience a decrease in overall precipitation levels from climate change, the region is also expected to see an increase in the number of extreme precipitation events.

A meteorological phenomenon known as the “atmospheric river,” a narrow stream of extremely moist air, is frequently responsible for the more intense storms that strike California. Atmospheric rivers generally deliver high levels of precipitation, up to 50 percent of the state’s total precipitation in any given year.

Because of this, floods are expected to occur more often in Wildomar and climate change may expand the parts of the city that are considered flood-prone. Although there are no specific flooding projections for the city, flood events are expected to become more frequent, and it is possible that the areas subject to flooding will expand.

There are some indirect effects of climate change that may also increase flooding in the city. Climate change is expected to increase the frequency and severity of droughts that cause soil to dry out and become hard. When precipitation does return, more water runs off the surface than is absorbed into the ground, which can lead to F-39

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-36 floods. Wildfires, which are also expected to become more frequent due to climate change, cause a similar effect by baking the surface of the ground into a harder and less-penetrable layer. Trees and other vegetation help slow water down, which lets the water absorb into the soil and prevents it from turning into runoff. Because of this, the loss of trees and other plants from wildfires, or other climate-related exposures can also increase flooding risk.

While the risk and associated short- and long-term impacts of climate change are uncertain, experts in this field tend to agree that among the most significant impacts include those resulting from increased heat and precipitation events that cause increased frequency and magnitude of flooding. Increases in damaging flood events will cause greater property damage, public health and safety concerns, displacement, and loss of life.

Displacement of residents can include both temporary and long-term displacement, increase in insurance rates, or restriction of insurance coverage in vulnerable areas.

GOAL S-3: To avoid the risk of loss of life and injury, and minimize the risk of damage to property, and economic and social dislocations resulting from flooding and inundation hazards.

FIRE HAZARDS
Fire hazards include both wildfires and urban fires. California is recognized as one of the most fire-prone and consequently fire-adapted landscapes in the world. The combination of complex terrain, Mediterranean climate, and productive natural plant communities, along with ample natural ignition sources, has created conditions for extensive wildfires. Wildfire is an ongoing concern for the City of Wildomar. Generally, the fire season extends from early spring through late fall of each year during the hotter, dryer months. Fire conditions arise from a combination of high temperatures, low-moisture content in the air and plant matter, an accumulation of vegetation, and high winds. Three types of fires are of concern to Wildomar: (1) wildfires, (2) wildland-urban interface fires, and (3) structural fires.

WILDFIRES
Wildfires occur on mountains, hillsides, and grasslands. Vegetation, wind, temperature, humidity, and slope are all factors that affect how these fires spread. In Wildomar, native vegetation, such as chaparral, sage, and grassland provide fuel that allows fire to spread easily across large tracts of land. These plant species are capable of regeneration after a fire, making periodic wildfires a natural part of the ecology of these areas. Portions of the city are undeveloped and consist of rugged topography with highly flammable vegetation. In particular, the hillside terrain in the southwestern region near the Elsinore Mountains, as well as the hillside terrain east of I15, have a substantial fire risk. Undeveloped hillside areas in and adjacent to the city present a serious hazard because of the potential for large-scale wildland fires. Fire potential for Riverside County is typically greatest in the months of August, September, and October, when dry vegetation coexists with hot, dry Santa Ana winds.

However, in Wildomar, fires with conflagration potential can occur at any time of the year. Seasonal drought conditions exacerbate fire hazards.

WILDLAND-URBAN INTERFACE FIRES
The wildland-urban interface is an area where buildings and infrastructure (e.g., cell towers, schools, water supply facilities) mix with areas of flammable wildland vegetation. The WUI is made up of three distinct zones.

The intermix zone contains housing development or improved parcels interspersed in an area dominated by wildland vegetation subject to wildfire. The interface zone contains dense housing next to vegetation, but not dominated by wildland vegetation, that can burn in a wildfire. The influence zone contains wildfire-susceptible vegetation within 1.5 miles from the WUI or wildland-urban intermix zones. Hundreds of homes now border major forests and brush areas. With thousands of people living near and visiting wildland areas, the probability of human-caused fires is growing. Wildfires and urban interface fires have occurred close to or encroached into the city, especially in large areas of grassland, scrub, and chapparal. The most recent fire was the 2019 Tenaja F-45

2017

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-42 Fire, located south of Wildomar in the rural community of La Cresta. The fire burned approximately 1,926 acres and damaged three structures but did not encroach into the city. Other notable fires that occurred within Wildomar are listed in Table S-2.

In the wildland-urban interface, efforts to prevent ignitions and limit wildfire losses hinge on hardening structures and creating defensible space through a multi-faceted approach, which includes engineering, enforcement, education, emergency response, and economic incentive. Different strategies in the defense and threat zones of the wildland-urban interface help to limit the spread of fire and reduce the risk to people and property.

Wildfire threat within California is described by Wildfire Hazard Severity Zones, which designate hazardous areas within State Responsibility Areas (SRAs) as moderate, high, or very high. However, incorporated areas such as Wildomar are considered Local Responsibility Areas (LRAs) and only designate very high fire hazard severity zones. Significant portions of the city are located within a very high fire hazard severity zone. Figure 7-0 shows the wildfire risk zones in and around Wildomar and Figure 8-0 identifies the wildland-urban interface.

The highest threat occurs along the eastern side of I-15, as well as the western side of Grand Avenue, on land that is on and adjacent to hillsides with large areas of dry grass and chapparal. Areas adjacent to the city that are susceptible to wildfires are also of concern as these conditions could exacerbate vulnerabilities within the city.

As illustrated in Figure 7-0, the highest threat for vulnerable communities occurs in the northern region of the city, north of Lemon Street and east of I-15. These communities are entirely within a very high fire hazard severity zone.

STRUCTURAL FIRES
Urban fires occur in built-up environments, destroying buildings and other human-made structures. These disasters are often due to faulty wiring or mechanical equipment, combustible construction materials, or the absence of fire alarms and fire sprinkler systems. Structural fires are largely from human accidents, although deliberate fires (arson) may be a cause of some events. Older buildings that lack modern fire safety features may face greater risk of damage from fires. To minimize fire damage and loss, the City’s Fire and Building Codes, based on the California Fire and Building Codes, sets standards for building and construction. It requires the provision of adequate water supply for firefighting, fire-retardant construction, and minimum street widths, among other things. Fire prevention awareness programs and fire drills are conducted to train residents to respond quickly and correctly to reduce injury and losses during fires.

FIRE PROTECTION
Fire protection in Wildomar is provided by the Riverside County Fire Department and the California Department of Forestry and Fire Protection (CAL FIRE). The City has a partnership with the Riverside County Fire Department and CAL FIRE to provide fire suppression, emergency medical, technical rescue, fire prevention, and related services to the city. The Riverside County Fire Department and CAL FIRE participate in a Cooperative Fire Response Agreement, where fire agencies have agreed to automatically support each other on incidents using the closest available resource.

The Riverside County Fire Department is one of the largest regional fire service organizations in California. It is staffed with a combination of County of Riverside and CAL FIRE personnel and responds to both urban and wildland emergencies. The Riverside County Fire Department serves a vast geographic area and diverse communities. Wildomar Fire Station 61 is located at 32637 Gruwell Street in the City of Wildomar.

POTENTIAL CHANGES TO FIRE RISK IN FUTURE YEARS
Likelihood of Future Occurrence
Wildomar is at a high risk from wildfire, especially in the areas of grassland and chapparal along hillsides. High fuel loads in the city, along with geographical and topographical features, create the potential for both natural and human-caused fires that can result in loss of life and property. These factors, combined with natural weather conditions common to the area, including periods of drought, high temperatures, low relative humidity, and periodic winds, can result in frequent and sometimes catastrophic fires. During the historic fire season, August to October, the dry vegetation combined with continued growth in the wildland-urban interface areas, resulted in wildfire ignitions. Any fire, once ignited, has the potential to quickly become a large, out-of-control fire. As development continues throughout the city, especially in these interface areas, the risk and vulnerability to wildfires will likely increase.

Fire hazard is among the highest-priority hazards in the city and is the hazard with the greatest potential for catastrophic loss. Wildfires can cause short-term and long-term disruption to the City, such as devastating effects on watersheds through loss of vegetation and soil erosion, which may impact the city by changing runoff patterns, increasing sedimentation, reducing natural and reservoir water storage capacity, and degrading water quality. Fires may also result in casualties and can destroy buildings and infrastructure. c======================-=-=-=
F-51
- 2023

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-48 Although the physical damages and casualties arising from wildland-urban interface fires may be severe, it is important to recognize that they also cause significant economic impacts by resulting in a loss of function of buildings and infrastructure. In some cases, the economic impact of this loss of services may be comparable to the economic impact of physical damages or, in some cases, even greater. Economic impacts of loss of transportation and utility services may include traffic delays/detours from road and bridge closures and loss of electric power, potable water, and wastewater services. Fires can also cause major damage to power plants and power lines needed to distribute electricity to operate facilities. The effects can be far-reaching in terms of the number of acres involved, the toll on human life, and the economic consequences. Fire will continue to be a high-risk hazard for the City of Wildomar.

Climate Change and Wildfire
Changing climate conditions are expected to increase the wildfire risk in and around Wildomar. Warmer temperatures brought on by climate change can exacerbate drought conditions. Droughts can kill or dry out plants, creating more fuel for wildfires. Warmer temperatures are also expected to increase the number of pest outbreaks, such as the shot hole borer, creating more dead trees and increasing the fuel load. Warmer temperatures are also expected to occur later in the year, extending the wildfire season, which is likely to begin earlier in the year and extend later than it has historically. Wildfire occurring later or earlier in the year are more likely to occur during Santa Ana wind events, which can cause wildfires to move more quickly and increase the likelihood to burning in the wildland-urban interface areas. According to the California Fourth Climate Change Assessment, overall burned area may increase by as much as 60 percent during Santa Ana wind events (typically October to March), and 75 percent during periods without Santa Ana winds (typically April to September).

GOAL S-4: To avoid the risk of loss of life and injury and minimize risk of property damage, community disruption, and economic loss resulting from urban and wildland fires.

AIR POLLUTION
Healthy air quality can be defined as the degree to which ambient air is pollution free. Although air pollution has been regulated for decades, California still has some of the worst air in the country. Air pollution can cause many serious health effects. For example, inhaling small particles called particulate matter can lead to asthma attacks and heart and lung disease with smaller particles capable of traveling farther into the lungs.

The specific pollutants of concern in Wildomar include diesel particulate, ozone, and PM2.5. Diesel particulate is considered a toxic air contaminant (TAC). TACs are air pollutants that can cause serious health effects from exposure at extremely low levels – a safe level of exposure may not even exist. Diesel particulate is a particulate matter from diesel-fueled engines. Ozone and PM2.5 are two of six criteria air pollutants that harm health and the environment for which the US Environmental Protection Agency (EPA) and California set acceptable concentration levels for ambient air. Criteria and toxic air pollutants can cause some of the most severe health impacts.
• People exposed to diesel particulate at sufficient concentrations and durations may have an increased chance of getting cancer or experiencing other serious health effects. Health effects can include damage to the immune system as well as neurological, reproductive (e.g., reduced fertility), developmental, respiratory, and other health problems. Almost all diesel exhaust particles are 10 microns or less in diameter. Because of their extremely small size, these particles can be inhaled and eventually trapped in the bronchial and alveolar regions of the lungs. Long-term (chronic) inhalation of diesel particulate matter is likely a lung cancer risk. Short-term (i.e., acute) exposure can cause irritation and inflammatory responses and may exacerbate existing allergies and asthma. • Ozone is a key ingredient of “smog” and is a gas that is formed when volatile organic compounds (VOCs) and oxides of nitrogen (NOX), both by-products of internal combustion engine exhaust, undergo photochemical reactions in sunlight. Ozone is a secondary criteria air pollutant. Ozone concentrations are generally highest during the summer months when direct sunlight, light winds, and warm temperatures create favorable conditions for its formation. Ozone poses a health threat to those who c======================-=-=-=

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-55 already suffer from respiratory diseases as well as to healthy people. Breathing ozone can trigger a variety of health problems, including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ground-level ozone also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue. Ozone also affects sensitive vegetation and ecosystems, including forests, parks, wildlife refuges, and wilderness areas. • PM2.5 is a suspended particulate matter that consists of finely divided solids or liquids such as soot, dust, aerosols, fumes, and mists. Inhalable fine particles, or PM2.5, have an aerodynamic diameter of

2.5 microns or less (i.e., ≤2.5 millionths of a meter or 0.0001 inch). Particulate discharge into the atmosphere results primarily from industrial, agricultural, construction, and transportation activities.

PM2.5 may adversely affect the human respiratory system, especially in people who are naturally sensitive or susceptible to breathing problems. The EPA’s scientific review concluded that PM2.5, which penetrates deeply into the lungs, is more likely than PM10 to contribute to health effects and at far lower concentrations. These health effects include premature death in people with heart or lung disease, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function, and increased respiratory symptoms. Particulate matter can also cause environmental effects, such as visibility impairment, environmental damage, and aesthetic damage.

Vulnerable communities in Wildomar face compounded health risk from exposure to elevated concentration levels of diesel particulate, ozone, and PM2.5. These communities are exposed to multiple health risks from pollutants such as these, while concurrently living in unhealthy housing conditions and/or experiencing poverty and other socioeconomic stressors that are associated with negative health outcomes. Although these conditions can occur anywhere throughout Wildomar, they are more often experienced by vulnerable communities. As illustrated in Figures 10-0 through 12-0, air pollution impacts to vulnerable communities is greatest in the northwest region of the city, along Corydon Road and Mission Trail. According to these figures, over 15 percent of the population’s income in this region is below the 2019 poverty level.

Figure 10-0 shows that the diesel particulate percentile is 1 to 20 percent (lowest scores) for vulnerable communities living near Palomar Street, Corydon Road, and Bundy Canyon Road. To the north of Lemon Street (Sedco Hills), diesel particulate percentile is 41 to 60 percent for vulnerable communities living to the west and east of I-15.

Figure 11-0 shows that the ozone percentile is 71 to 80 percent for vulnerable communities living near Palomar Street, Corydon Road, and Bundy Canyon Road. To the north of Lemon Street (Sedco Hills), ozone percentile is 81 to 90 percent for vulnerable communities living to the west and east of I-15. c======================-=-=-=

POLICY S-69 Require a cumulative health risk assessment, including consideration of truck traffic impacts, when a project potentially affects sensitive receptors in vulnerable communities, and require appropriate mitigation based on the findings of the assessment.

POLICY S-70 Require new development to locate sensitive receptors, such as homes, schools, playgrounds, sports fields, childcare centers, senior centers, and long-term health care facilities as far away as possible from significant pollution sources.

POLICY S-71 When evaluating air quality impacts of projects in vulnerable communities, use thresholds of significance that match or are more stringent than the air quality thresholds of significance identified in the current South Coast Air Quality Management District (SCAQMD) Air Quality Guidelines.

POLICY S-72 Preserve, restore, and enhance natural landscapes in and near vulnerable communities for their role in improving air quality and community health.

POLICY S-73 Prioritize new street tree plantings and increase the tree canopy in vulnerable communities, in particular areas with high elevated concentration levels of diesel particulate, ozone, and PM2.5.

HAZARDOUS WASTE AND MATERIALS
Hazardous materials are materials that pose a significant risk to public safety or human or environmental health.

These include toxic chemicals, flammable or corrosive materials, petroleum products, and unstable or dangerously reactive materials. They can be released through human error, malfunctioning or broken equipment, or as an indirect consequence of other emergencies (e.g., if a flood damages a hazardous material storage tank).

Hazardous materials can also be released accidentally during transportation, as a consequence of vehicle accidents.
c======================-=-=-=
F-64
- 2036

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-61 A release or spill of bulk hazardous materials could result in fire, explosion, toxic cloud, or direct contamination of water, people, and property. The effects may involve a local site or many square miles. Health problems may be immediate, such as corrosive effects on skin and lungs, or gradual, such as the development of cancer from a carcinogen. Damage to property could range from immediate destruction by explosion to permanent contamination by a persistent hazardous material.

Most hazardous materials in the region are being transported on truck routes along major roadways, such as I15. Southern California Edison is currently in the process of decommissioning the San Onofre Nuclear Generating Station. The site is in Pendleton, California, approximately 22 miles southwest of Wildomar.

Decommissioning is a well-defined Nuclear Regulatory Commission process that involves safely transferring the used nuclear fuel into storage, followed by the eventual removal and disposal of radioactive components and materials from the site. Decommissioning removes radiological material from the site and eliminates potential industrial hazards. Radiological material, including low-level radioactive waste from the site, and other hazardous materials could potentially be transported via I-15 through Wildomar to be disposed of in other locations. The most vulnerable areas along this route are considered the on-/off-ramps and interchanges. Since 1970, there have been no reported roadway hazardous materials incidents.

Several state agencies monitor hazardous materials/waste facilities. Potential and known contamination sites are monitored and documented by the Regional Water Quality Control Board (RWQCB) and the Department of Toxic Substances and Controls (DTSC). A review of the leaking underground storage tank list produced by the RWQCB and the DTSC EnviroStor database indicates two leaking underground storage tanks in the city at 33986 Orange Street and 36485 Inland Valley Drive and three school investigation cleanup sites at La Estrella Road/George Porras Road, 35450 Frederick Street, and Bundy Canyon Road/Orchard Street.

If an imminent public health threat is posed by an outside factor, the City will support local regulating agencies in notifying the public. The transport of hazardous materials/wastes and explosives through the city is regulated by the California Department of Transportation (Caltrans). I-15 is open to vehicles carrying hazardous materials/wastes. City streets are generally not designated as hazardous materials/waste transportation routes, but a permit may be granted on a case-by-case basis. Transporters of hazardous wastes are required to be certified by the United States Department of Transportation (DOT) and manifests are required to track the hazardous waste during transport. The danger of hazardous materials/waste spills during transport does exist and will potentially increase as transportation of these materials increase on I-15. The Riverside County Sheriff’s Department, Riverside County Fire Department, CAL FIRE, Riverside County EMD, and Riverside County Division of Environmental Health are responsible for hazardous materials accidents at all locations within the city.

Wildomar Safety Element – Adopted October 13, 2021 SE-62

POTENTIAL CHANGES TO HAZARDOUS MATERIALS IN FUTURE YEARS Likelihood of Future Occurrence
Given that there have been no hazardous materials incidents in transport through the city in the past 50 years, it is unlikely a hazardous materials incident will occur in Wildomar every year. Moreover, according to Caltrans, most incidents are related to releases of fluids from the transporting vehicles themselves and not the cargo, thus the likelihood of a significant hazardous materials release within the city is more limited and difficult to predict.

Climate Change and Hazardous Materials
Climate change is unlikely to affect hazardous materials transportation incidents. However, increases in the frequency and intensity of hazards, such as floods, landslides, and severe storms, may create a greater risk of hazardous materials releases during these events.

GOAL S-6: To avoid the risk of loss of life, injury, and serious illness and minimize damage to property and economic and social dislocations resulting from the use, transport, treatment, and disposal of hazardous materials and hazardous materials wastes.

POLICY S-74 Enforce land use policies and siting criteria related to hazardous materials and waste through ongoing implementation of the programs identified in the County of Riverside Hazardous Waste Management Plan (CHWMP).

POLICY S-75 Review all proposed development projects that manufacture, use, or transport hazardous materials for compliance with the CHWMP. Such projects shall provide a buffer zone, to be determined by the City, between the installation and property boundaries sufficient to protect public safety.

POLICY S-76 Require that applications for discretionary development projects that will generate hazardous wastes or use hazardous materials include detailed information on hazardous waste reduction, recycling, and storage.

POLICY S-80 Identify sites that are inappropriate for hazardous material storage, maintenance, use, and disposal facilities due to potential impacts on adjacent land uses and the surrounding natural environment. Prohibit the siting of new or expanded hazardous material sites on such sites, including areas identified as vulnerable communities.

POLICY S-81 Ensure that the use and disposal of hazardous materials in Wildomar complies with local, state, and federal safety standards.

POLICY S-82 Require commercial businesses, utilities, and industrial facilities that handle hazardous materials to install automatic fire and hazardous materials detection, reporting, and shut-off devices, and install an alternative communication system in the event power is out or telephone service is saturated following an earthquake, as required by the Wildomar Fire Code.

POLICY S-83 Prohibit any new facilities using, storing, or producing hazardous materials from being located directly adjacent to existing residential or school uses.

POLICY S-84 Encourage use of on-site green infrastructure to protect and enhance community water quality with landscape design (e.g., berms, grasslands, plantings) to either contain released hazardous materials or to process and/or absorb pollutants from infiltrating the soil or watershed.

DISASTER PREPAREDNESS, RESPONSE, AND RECOVERY
Riverside County Emergency Services establishes the responsibilities of the various Riverside County agencies in times of a disaster. Disaster preparedness and response planning includes identifying short-term actions to reduce the scope of an emergency and managing necessary resources in the event of a disaster. After any disaster, particularly an earthquake, short-term disaster recovery requires many operations that are less urgent than fire suppression or medical attention but are equally important.

EMERGENCY PREPAREDNESS
Emergency preparedness activities in Wildomar are conducted through the County of Riverside EMD. EMD, in cooperation with the City, and fire and law enforcement agencies, provides emergency management services.

EMD prepares emergency and contingency plans, ranging from evacuation plans to emergency operations plans that help specify the roles and responsibilities of first responders and emergency management personnel for an incident. Moreover, EMD plans and organizes trainings and exercises involving the City of Wildomar as well as other local, state, federal, and regional agencies.

The Riverside County Fire Department and CAL FIRE are prepared to handle most everyday emergencies, such as all types of fire, medical, or hazardous situations. However, during a disaster, the number and scope of incidents may exceed the fire department’s and CAL FIRE’s ability to provide effective emergency services.

For this reason, Wildomar provides the public with access to a community emergency response team (CERT) training program. The CERT Program provides for community and employee self-sufficiency to meet the general public’s urgent life-saving and sustenance needs until emergency personnel arrive. The CERT Program educates people about disaster preparedness and trains them in basic response skills, such as fire safety, light search and rescue, and disaster medical operations. CERT members assist their fellow citizens/coworkers in their community or workplace following a disaster. CERT members take an active role in their community by preparing for a disaster, thus reducing their own impact risk.

The City of Wildomar uses Alert RivCo, a phone alert system to alert residents and businesses in Riverside County who are affected, threatened, or might be endangered by an emergency event or a disaster, such as wildfires, floods, hazardous materials, severe weather, and certain law enforcement incidents. Alert RivCo is c======================-=-=-=

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-65 part of a group of alert and warning tools used in the county. Other systems include the Emergency Alert Systems (EAS) and the Emergency Digital Information System (EDIS).

The EAS is a national public warning system commonly used by state and local authorities to deliver important emergency information, such as weather and AMBER alerts, to affected communities. EAS participants – radio and television broadcasters, cable systems, satellite radio and television providers, and wireline video providers.

FEMA, the Federal Communications System, and National Oceanic and Atmospheric Administration’s (NOAA’s) National Weather Service (NWS) work collaboratively to maintain the EAS and Wireless Emergency Alerts, which are the two main components of the national public warning system and enable authorities at all levels of government to send urgent emergency information to the public. The EDIS is a wireless data cast-based emergency and disaster information service operated by the State of California Governor’s Office of Emergency Services and is an enhancement to the EAS. These systems are available in multiple languages. With advanced warning, evacuation can be effective in reducing injury and loss of life during a catastrophic event. Figure 13-0 shows residential parcels with evacuation constraints. All parcels within an evacuation constraint are located in a least one hazard-prone area and may have only one emergency evacuation route. The lack of multiple emergency access points limits roadway access for these properties, which may create difficulties if there is a need to evacuate, especially in vulnerable communities. Notably, the Farm Specific Plan project area (east of I-15 and south of Bundy Canyon Road) is within a hazard-prone area that lacks multiple emergency access points.

DISASTER PREPAREDNESS
In recent years, the County of Riverside has expanded its emergency preparedness planning. The County of Riverside is required under state law to prepare and maintain a Standardized Emergency Management System (SEMS) Multi-hazard Functional Plan. The California Governor’s Office of Emergency Services has extensive guidelines outlining the requirements of the Riverside County SEMS.

PUBLIC SAFETY POWER SHUTOFFS
The City of Wildomar is served by Southern California Edison (SCE). Electricity utilities throughout California, including SCE, have begun to occasionally “de-energize,” or turn off the electricity for, power lines that run through areas where there is an elevated fire risk. This is intended to reduce the risk of power lines sparking or being damaged and starting a wildfire. These activities, called public safety power shutoffs (PSPSs), result in a loss of power for customers served by the affected power lines. A PSPS may occur at any time of the year, usually during high wind events, high temperatures, and dry conditions. PSPS events may be limited to specific communities or they may affect broad swaths of the state. c======================-=-=-=
F-69
- 2041

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-66 In January 2021, SCE conducted one large-scale event in response to a Santa Ana wind event, shutting off power to approximately 114,000 customers, including those in Riverside County. In December 2020, SCE conducted two large-scale events shutting off power to approximately 95,000 customers, including those in Riverside County. The largest PSPS event during this time occurred on December 4 and ended on December 14, 2020.

During this event, 197,729 customers in seven counties (San Bernardino, Riverside, Orange, Kern, Los Angeles, Tuolumne, and Ventura) were identified as under consideration for PSPS. During this event, SCE de-energized circuits not originally in scope when unexpected high wind conditions were observed in the areas of concern.

Ultimately, SCE proactively de-energized 73,137 customers in areas of Inyo, Kern, Mono, Los Angeles, Orange, Riverside, San Bernardino, and Ventura Counties.

In October 2019, SCE conducted four large-scale events, shutting off power to approximately 160,000 customers, including those in Riverside County. The largest PSPS event during this time occurred on October 27 and ended on October 31, 2019. During this event, 498,660 customers in 12 counties (Fresno, Inyo, Kern, Los Angeles, Madera, Mono, Orange, Riverside, San Bernardino, Tulare, Tuolumne, and Ventura) served by 352 distribution circuits and seven transmission lines were identified as under consideration for PSPS.

Ultimately, proactive de-energization was required for 126 circuits (including three transmission lines) affecting 126,364 customers, including some in Riverside County, over two weather systems. PSPS events can impact emergency management activities. A loss of power can make it more difficult for homes or businesses to receive emergency notifications if needed. PSPS events can also create vulnerabilities for community members that lack backup power supplies and depend on electricity for heating or cooling homes and buildings, lighting, and internet. PSPS events may also be harmful to people who depend on electrically powered medical devices.

Additionally, community members may be faced with economic hardships and be deprived of important services, such as grocery stores, gas stations, and banks/ATMs. Traffic lights and other traffic control systems may not work, which can complicate any evacuation needs and may hinder emergency response (see Figure 13- 0 for evacuation constraints). Although critical public health and safety facilities often have backup generators, the loss of power may also disable other key infrastructure systems.

MUTUAL-AID AGREEMENTS
Additional emergency management and response services in Wildomar are provided through a mutual-aid agreement with the Riverside County Fire Department and CAL FIRE. The Riverside County Fire Department and CAL FIRE provide a variety of public safety services, including fire protection, medical aid, rescue, hazardous materials response, and educational safety programs. c======================-=-=-=

ADDITIONAL CLIMATE-RELATED HAZARDS

DROUGHT
A drought is a long period when precipitation levels are well below normal. Wildomar chronically experiences drought cycles. Since the 1950s, Riverside County has received an average of 8 inches of rainfall per year, although that number can vary greatly between years.

Drought makes less water available for people, businesses, agricultural activities, and natural systems. Less snow falling in mountainous areas causes water levels in lakes and reservoirs to drop, which can affect recreation activities. Local ecosystems that are not well adapted to drought conditions can be more easily harmed by it.

During drought events, the flow of water in creeks and streams is reduced, creating more slow-moving or standing water. This can concentrate sediment and toxins in the low water levels, causing harm to plants and animals. Many fish species also prefer specific stream flow speeds, especially for spawning and egg incubation, and changes to stream velocity as a result of drought conditions can affect reproduction. Droughts can also indirectly lead to more wildfires, and the stress caused by water shortages can weaken plants, making them more susceptible to pests and diseases.

The U.S. Drought Monitor recognizes a five-point scale for drought events: D0 (abnormally dry), D1 (moderate drought), D2 (severe drought), D3 (extreme drought), and D4 (exceptional drought). According to the U.S.

Drought Monitor, the most intensive drought conditions in recent years occurred during most of 2007, when all of Riverside County was classified as being in “extreme” drought. As of spring 2021, western Riverside County, including Wildomar, was classified as being in “moderate” drought. For 74 percent of the time since 2000, at least half of Riverside County has been under some level of drought conditions and 48 percent of the time since 2000, all of Riverside County has faced drought conditions. These figures do not include times when sources of Riverside County’s imported water may have also been under drought events.

Potential Changes to Drought in Future Years
Likelihood of Future Occurrence
Drought is different than many of the other natural hazards in that it is not a distinct event and usually has a slow onset. Drought can severely impact a region both physically and economically. Drought affects different sectors in different ways and with varying intensities. Adequate water is the most critical issue for commercial and domestic use. As the population in the city continues to grow, so will the demand for water. c======================-=-=-=
F-78
- 2050

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-75 Based on historical information, the occurrence of drought in California, including Riverside County, is cyclical, driven by weather patterns. Drought has occurred in the past and will occur in the future. Periods of actual drought with adverse impacts can vary in duration, and the period between droughts is often extended. Although an area may be under an extended dry period, determining when it becomes a drought is based on impacts to individual water users. The impacts of Wildomar to drought include reduction in water supply and an increase in dry fuels.

Most of the imported water used comes from the State Water Project via the Sierra Nevada range and the Colorado River Aqueduct. Reduced winter precipitation levels and warmer temperatures have greatly decreased the size of the Sierra Nevada snowpack (the volume of accumulated snow), which in turn makes less fresh water available for communities throughout California. Continued decline in the Sierra Nevada snowpack volume is expected, which may lead to lower volumes of available imported water.

Climate Change and Drought
Although droughts are a regular feature of California’s climate, scientists expect that climate change will lead to more frequent and more intense droughts statewide. Overall, precipitation levels are expected to stay similar, and may even increase in some places. However, the state’s current data say that there will be more years with extreme levels of precipitation, both high and low, as a result of climate change. This is expected to cause more frequent and intense droughts compared to historical norms. Higher air temperatures are expected to increase evaporation, causing more water loss from lakes and reservoirs, exacerbating drought conditions.

EXTREME HEAT
While there is no universal definition of extreme heat, California guidance documents define extreme heat as temperatures that are hotter than 98 percent of the historical high temperatures for the area, as measured between April and October of 1961 to 1990. Days that reach this level are called extreme heat days. In Wildomar, the extreme heat threshold is 105°F. An event with five extreme heat days in a row is called a heat wave.

Health impacts are the primary concern with this hazard, though economic impacts are also an issue. The Centers for Disease Control and Prevention (CDC) recognizes extreme heat as a substantial public health concern.

Historically, NOAA data indicates that about 175 Americans succumb to the demands of summer heat, although this number has increased in recent years. From 2004 to 2018, studies by the U.S. Department of Health and Human Services indicate that there is an average of 702 deaths annually that are directly or indirectly linked to extreme heat.
c======================-=-=-=
F-79
- 2051

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-76 Extreme heat events are dangerous because people exposed to extreme heat can suffer a number of heat-related illnesses, including heat cramps, heat exhaustion, and (most severely) heat stroke. Elderly persons, small children, chronic invalids, those on certain medications or drugs, and persons with weight and alcohol problems are particularly susceptible to heat reactions. The elderly and individuals below the poverty level are the most vulnerable to extreme heat. Nursing homes and elder-care facilities are especially vulnerable to extreme heat events if power outages occur, and air conditioning is not available. In addition, individuals below the poverty level may be at increased risk to extreme heat if use of air conditioning is not affordable. Areas with lower extreme heat thresholds are not necessarily at lower risk, as persons and community assets used to cooler temperatures may be less prepared for extreme heat events.

Very high temperatures can harm plants and animals that are not well adapted to them, including natural ecosystems. Extreme heat can increase the temperature of water in lakes, streams, creeks, and other water bodies, especially during drought events when water levels are lower. In some cases, water temperatures may exceed comfortable levels for a number of plants and animals, causing ecological harm. Outdoor workers in construction or landscaping are also much more exposed to the elements than most people, so they are more susceptible to extreme heat conditions and the potential illnesses associated with very high temperatures.

Indirectly, extreme heat puts more stress on power lines, causing them to run less efficiently. The heat also causes more demand for electricity (usually to run air conditioning units), and in combination with the stress on the power lines, may lead to brownouts and blackouts.

Potential Changes to Extreme Heat in Future Years
Likelihood of Future Occurrence
Extreme heat tends to occur on an annual basis and is likely to continue occurring annually. As Wildomar is located in western Riverside County and at relatively low elevation, extremely high temperatures will continue to be a more common occurrence than cold temperatures.

Climate Change and Extreme Heat
The warmer temperatures brought on by climate change are likely to cause an increase in extreme heat events.

Depending on the location and emissions levels, the state Cal-Adapt database indicates the number of extreme heat days is expected to rise from a historical annual average of 4 to between 25 and 37 by the middle of the century (2041 to 2060), and to between 34 and 58 by the end of the century (2070 to 2099). c======================-=-=-=
F-80
- 2052

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-77 Overall, Wildomar is expected to see an increase in the average daily high temperatures. Although the temperature increases may appear modest, the projected high temperatures are substantially greater than historical norms. These increases also make it more likely that an above-average high temperature will cross the extreme heat threshold. As temperatures increase, Wildomar will face increased risk of death from dehydration, heat stroke, heat exhaustion, heart attack, stroke, and respiratory distress caused by extreme heat.

SEVERE WEATHER
Severe weather is generally any destructive weather event, but usually occurs in Wildomar as localized storms that bring heavy rain, hail, lightning, and strong winds. Severe weather is usually caused by intense storm systems, although types of strong winds can occur without a storm. The types of dangers posed by severe weather vary widely and may include injuries or deaths, damage to buildings and structures, fallen trees, roads and railways blocked by debris, and fires sparked by lightning. Severe weather often produces high winds and lightning that can damage structures and cause power outages. Lightning from these storms can ignite wildfires and structure fires that can cause damage to buildings and endanger people. Objects can also be struck directly, which may result in an explosion, burn, or total destruction. Lightning happens occasionally and there have been six injuries and one death reported from lightning events since 1950. Hail events are rare and there have been no reported injuries from hail in Wildomar. In Riverside County, most severe weather is linked to high winds.

High winds, often accompanying severe storms, can cause significant property and crop damage, threaten public safety, and have adverse economic impacts from business closures and power loss.

Santa Ana winds have caused large amounts of damage and increased the fire damage level dramatically. Santa Ana winds are generally defined as warm, dry winds that blow from the east or northeast (offshore). These winds occur below the passes and canyons of the coastal ranges of Southern California. Santa Ana winds often blow with exceptional speed in the Santa Ana Canyon. The complex topography of Southern California, combined with various atmospheric conditions, creates numerous scenarios that may cause widespread or isolated Santa Ana events. Commonly, Santa Ana winds develop when a region of high pressure builds over the Great Basin (the high plateau east of the Sierra Nevada and west of the Rocky Mountains, including most of Nevada and Utah). Santa Ana winds commonly occur between October and April with December having the highest frequency of events. Summer events are rare. Wind speeds are typically north to east at 40 miles per hour (mph) through and below passes and canyons with gusts to 58 mph. Stronger Santa Ana winds can have gusts greater than 69 mph over widespread areas and, in rare instances, gusts greater than 115 mph in specific areas. Frequently, the strongest winds in the basin occur during the night and morning hours due to the absence of a sea breeze.
c======================-=-=-=
F-81
- 2053

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-78 All wind events, including Santa Ana winds, pose several different types of threats. By themselves, the winds pose a threat to the health of people and structures in the county. Dust and plant pollen blown by the wind can create breathing problems. The winds can blow roofs off buildings and cause tree limbs to fall on structures.

High winds also increase the threat of wildfires. Winds may dry out brush and forest areas, increasing the fuel load in fire-prone areas. Winds may spark wildfires by knocking down power lines or causing them to arc. If fires do start, high winds can push flames quickly into new areas, contributing to rapid spread of wildfires and making them harder to control.

Potential Changes to Severe Weather in Future Years
Likelihood of Future Occurrence
According to historical hazard data, severe weather is an annual occurrence in western Riverside County.

Damage and disaster declarations related to severe weather have occurred and will continue to occur in the future. Heavy rain and thunderstorms are the most frequent type of severe weather occurrences in the county.

Wind and lightning often accompany these storms and have caused damage in the past. However, actual damage associated with the primary effects of severe weather have been limited. It is the secondary hazards caused by severe weather, such as floods and fire, that have had the greatest impact on the county. In general, any severe storm that affects Riverside County has local effects in Wildomar as well. Thunderstorms, high winds, and lightning can each have localized impacts on infrastructure, properties, and public safety. Transportation, including freight shipping, faces increased congestion when severe storms occur.

Climate Change and Severe Weather
Climate change is expected to cause an increase in intense rainfall, which is usually associated with strong storm systems. This means that Wildomar could see more intense storms in the coming years and decades. Such an increase may not affect all forms of severe weather and may not always be apparent.

While average annual rainfall may increase only slightly, climate change is expected to cause an increase in the number of years with intense levels of precipitation. Heavy rainfall can increase the frequency and severity of other hazards, including flooding and landslides. Climate change is also expected to increase the total number of intense storms that affect Wildomar, possibly causing an increase in the frequency of severe weather events and any associated hazards. Some already-rare forms of severe weather, such as tornados, are not expected to increase in a noticeable way.

SAFETY ELEMENT
Wildomar Safety Element – Adopted October 13, 2021 SE-90 APPENDIX A: VULNERABILITY ASSESSMENT RESULTS
The table below shows the results of the Vulnerability Assessment prepared for Wildomar, in accordance with the requirements of Senate Bill 379. For each population or asset that may be vulnerable to each climate-related hazard, the population or asset is scored on a scale of zero to five:
0: Not vulnerable
V1: Minimal vulnerability
V2: Low vulnerability
V3: Moderate vulnerability
V4: High vulnerability
V5: Severe vulnerability
The vulnerability scores reflect both the severity of climate-related impacts and the ability of populations and assets to resist and recover from these effects. Refer to the “Climate Change” and “Vulnerable Populations and Assets” sections of the Safety Element for additional details on the Vulnerability Assessment method.

1. Introduction

1.1 PURPOSE OF MITIGATION MONITORING AND REPORTING

PROGRAM
The City of Wildomar (City) is the lead agency for the City of Wildomar Proposed General Plan (proposed project) and has developed this Mitigation Monitoring and Reporting Program (MMRP) as a vehicle for monitoring and ensuring the successful implementation of mitigation measures outlined in the City of Wildomar Proposed General Plan EIR, State Clearinghouse No. 2023090064. As the lead agency, the City is responsible for implementing the MMRP, which has been prepared in conformance with Section 21081.6 of the California Public Resources Code, as follows:
(a) When making findings required by paragraph (1) of subdivision (a) of Section 21081 or when adopting a mitigated negative declaration pursuant to paragraph (2) of subdivision (c) of Section 21080, the following requirements shall apply:
(1) The public agency shall adopt a reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment. The reporting or monitoring program shall be designed to ensure compliance during project implementation. For those changes which have been required or incorporated into the project at the request of a responsible agency or a public agency having jurisdiction by law over natural resources affected by the project, that agency shall, if so requested by the lead or responsible agency, prepare and submit a proposed reporting or monitoring program. (2) The lead agency shall specify the location and custodian of the documents or other material which constitute the record of proceedings upon which its decision is based.

The MMRP consists of mitigation measures that avoid, reduce, and/or fully mitigate potential environmental impacts. The mitigation measures have been identified and recommended through preparation of the EIR and drafted to meet the requirements of Public Resources Code, Section 21081.6.
