INTRODUCTION
1. INTRODUCTION
Safety is an important indicator of a community's quality of life. Moorpark residents
recognize that limited or controlled exposure to hazardous environmental conditions and
good emergency response services contribute to the overall livability of their community.
The Safety Element addresses safety issues arising from both naturally occurring and
human - caused conditions, and presents goals and policies focused on reducing the
potential risk of death, injuries, property damage, and economic and social dislocation
resulting from hazards. Examples of ways Moorpark can use the Safety Element
analysis include: (1) identifying fault zones to guide development approaches; (2)
determining the probability and location of flooding to help identify properties most likely
impacted by flood events; and (3) identifying the use of hazardous materials in
commercial, industrial, and household products to help reduce the risk of hazardous
waste contamination and accidents.
Hazards include earthquakes, dam or reservoir failure, contamination of soil and local
water resources, hazardous materials associated with commercial and industrial
business activity, and fire. These hazards can impact the lives of residents and
business employees within Moorpark by triggering the disruption of essential facilities
and systems such as water, sewer, gas, electricity, transportation, communications,
irrigation and drainage systems.
Public safety and service issues relevant to Moorpark are:
➢ Geologic and Seismic Hazards
➢ Hazardous Materials and Wastes
➢ Flooding and Water Contamination
➢ Fire Hazards
➢ Emergency Preparedness
The Safety Element presents the City's approaches to addressing these issues in the
context of goals and policies. Goals are overall statements of purpose and direction.
The policies serve as guidelines for reducing the risk associated with natural and human
activity hazards, and also direct and maximize community emergency preparedness.

IMPORTANT TERMS AND CONCEPTS
(1^ 2. IMPORTANT TERMS AND CONCEPTS
This Element uses the following technical terms to discuss earthquakes and flood
conditions.
A. Earthquake Magnitude
Moorpark lies within a region where earthquakes are not an uncommon occurrence.
Earthquakes result from a shift or movement along weak points or contacts of geologic
formations or structures. Scientists use the term magnitude to describe the relative
energy release by such movement. An earthquake's magnitude is based on the size of
the earthquake's seismic waves, which are recorded on a seismograph. Magnitude
generally is related and expressed using a logarithmic scale.
The amount of energy released, for example, from a 6.0 earthquake is 10 times greater
than that associated with a 5.0 event. Scientists consider a large earthquake as one
having a magnitude of 7.0 or greater. For purposes of comparison, the 1987 Whittier
earthquake registered a 5.9 magnitude, while the 1994 Northridge temblor measured 6.7
magnitude.
Magnitude differs from earthquake intensity, which is the physical, observable effects an
earthquake has on structures and people. News media generally do not report
earthquake intensity according to scales or references; instead, the media rely upon
pictures and comparisons to past events to show how an earthquake affects people and
` property. The Modified Mercalli scale has been developed to describe an earthquake's
intensity relative to its magnitude. Table 2 -1 presents the Modified Mercalli scale.
The Modified Mercalli Scale represents a subjective measurement or description of
ground shaking associated with a seismic event. The peak (maximum) horizontal
ground acceleration, or PGHA, is used by seismologists to quantitatively measure
ground shaking at particular locations. These values - expressed in units of g, which is a
fraction or percentage of gravitational acceleration - provide useful information for
determining how buildings must be constructed to withstand collapse or other damage in
the event of an earthquake.
B. Flood Events
The Federal Emergency Management Agency (FEMA) is mandated by the National
Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973 to evaluate
flood hazards and provide Flood Insurance Rate Maps for local and regional planners to
promote sound land use and floodplain development. Using information gathered in
engineering studies, FEMA engineers and cartographers determine Special Flood
Hazard Areas (SFHAs). SFHAs are those areas that have a 1 % chance of a major flood
event occurring in any one year. This type of flood is referred to as the "base flood" or
100 -year flood. The base flood is a regulatory standard used by the National Flood
Insurance Program as the basis for insurance requirements nationwide. Flood hazard
planning practices addresses such storms, as well as, for example, 50 -year and 500 -
year events.

RELATED PLANS AND PROGRAMS
f. 3. RELATED PLANS AND PROGRAMS
Regional plans and programs related to public safety include the State Seismic Hazards
Mapping Act, the California Environmental Quality Act (CEQA) Law and Guidelines, the
Alquist - Priolo Earthquake Fault Zoning Act, the Uniform Building Code, and the Federal
Emergency Management Agency (FEMA) Flood Insurance Program. Other plans and
programs are important to consider to ensure that the City has strong, comprehensive,
and compatible tools to guide development decisions. Also, pursuant to State law, the
City has developed a comprehensive emergency response plan.
A. California Seismic Hazards Mapping Act
California's Seismic Hazards Mapping Act of 1990 requires the State Geologist to
compile maps identifying and describing seismic hazards zones throughout
California. Guidelines prepared by the State Mining and Geology Board identify the
responsibilities of State and local agencies in the review of development within
seismic hazard zones. Development on a site that has been designated as a
seismic hazard zone requires a geotechnical report and local agency consideration
of the policies and criteria established by the Mining and Geology Board. Over the
years, the program has expanded to include mapping of seismic - related hazards
such as landslide -prone areas.
B. The Alquist- Priolo Earthquake Fault Zoning Act
'1 The Alquist - Priolo Special Studies Zones Act was signed into law in 1972 (in 1994 it
was renamed Alquist - Priolo Earthquake Fault Zoning Act). The primary purpose of
the Act is to mitigate the hazard of fault rupture by prohibiting the location of
structures for human occupancy across the trace of an active fault. The Act only
addresses the hazard of surface fault rupture and is not directed toward other
earthquake hazards.
f
C. FEMA Flood Insurance Program
The National Flood Insurance Act includes provisions for the National Flood
Insurance Program (NFIP). Participating jurisdictions must exercise land use
controls and purchase flood insurance as a prerequisite for receiving funds to
purchase or build a structure in a flood hazard area. The NFIP provides federal flood
insurance subsidies and federally financed loans for eligible property owners in flood -
prone areas.
D. Uniform Building Code
The Uniform Building Code (UBC) is the primary tool used by local agencies to
ensure seismic safety in structures. The code defines minimum lateral forces to
resist seismic shaking, the use and purpose of the structure, the seismic zone, and
four types of soil which effect degrees of shaking.

RELATED PLANS AND PROGRAMS
E. California Environmental Quality Act (CEOA)
The State legislature adopted CEQA in 1970 to ensure that environmental protection
received due consideration in the planning and development process. CEQA
requires a thorough analysis of potential environmental consequences which could
result from a development project or plan that guides future development. CEQA
provides a means by which City officials and the public can identify the potential
impacts a project will have on a community, and to allow for mitigation or avoidance
of such impacts.
City of Moorpark 3 -2 Safety Element
GEOLOGIC AND SEISMIC HAZARDS
�. 4. GEOLOGIC AND SEISMIC HAZARDS
A. Local Geologic Conditions
Moorpark is located in the Transverse Ranges physiographic province of southern
California. The characteristic landforms that define this province are a series of
predominantly east -west trending mountain ranges and their intervening valleys. The
ranges encompass Ventura County, as well as parts of San Bernardino, Riverside, Los
Angeles and Santa Barbara counties. At the base of the mountains, in the southern part
of the Moorpark area, the floodplain of the Arroyo Simi forms the Little Simi Valley.
Elevations along the valley floor range from about 400 to 600 feet.
Moorpark is underlain by primarily two types of geologic units: relatively weak semi -
consolidated sedimentary bedrock in the hilly and mountainous areas, and loose,
unconsolidated, often saturated, alluvial sediments in the valleys and canyon bottoms.
Volcanic rock has been mapped locally in the Tierra Rejada area.
In general, the City lies between two active fault systems; the Oak Ridge fault on the
north and the Simi -Santa Rosa fault on the south. The surface trace of the Oak Ridge
fault is located at the foot of the Oak Ridge Mountains in the Santa Paula Valley and
therefore does not traverse the City. The Simi -Santa Rosa fault passes longitudinally
through the Las Posas Hills. The geologic structure between the two fault zones
consists of fold and thrust terrain. In general, this terrain is more complex and less well
understood than that associated with other types of fault systems, and often includes
�^ areas of secondary faulting. Such secondary features are not capable of generating
earthquakes on their own, but instead are deforming the ground in response to regional
stresses and movements on the larger, mountain - bounding fault system.
rI--
B. Seismic Hazards
Movement along a fault releases stored energy and tension, thereby producing
earthquakes. While the Moorpark area is at risk from many natural and man -made
hazards, the event with the greatest potential for loss of life or property and economic
damage is an earthquake.
1. Faults and Earthquakes
Moorpark lies within a region with several active faults and therefore is subject to the
risk and hazards associated with earthquakes. Faults that have the greatest impact
on the Moorpark area include:
San Andreas Fauk Zone — The San Andreas fault is the principal boundary
between the Pacific and North American Plates and is comprised of five
segments. The Carrizo and Mojave segments, which extend from central
California to San Bernardino, are closest to the Moorpark area, where they join
near the Tejon Pass (approximately 35 miles away). These segments are
City of Moorpark 4 -1 Safety Element
GEOLOGIC AKD SEISMIC HAZARDS
estimated capable of producing magnitude 7.2 and 7.1 earthquakes,
respectively. A rupture of either segment would result in peak ground
accelerations in Moorpark ranging from about 0.06 g to 0.10 g.
Simi -Santa Rosa Fault Zone - The Simi -Santa Rosa Fault Zone consists of a
series of closely spaced faults that extend in an east - northeast direction across
the central part of Ventura County for a distance of more than 25 miles. In the
Moorpark area, numerous subparallel, discontinuous faults have been mapped
within the fault zone, as well as several fault splays that branch off the main
faults to the northeast. Seismic activity along the fault zone appears to be
relatively low, although the data is very limited. Evidence does suggest,
however, a compressional stress system.
In the southern part of Moorpark, the California Division of Mines and Geology
has designated an Alquist - Priolo Fault Zone for many of the traces of the Simi -
Santa Rosa fault zone. The City requires development proposal involving large
structures or subdivisions of more than four units to be accompanied by a
geology report that locates any surface trace of the Simi -Santa Rosa Fault and
designates appropriate setback distances from the surface traces of the fault.
Figure 4 -1 shows the Alquist Priolo Earthquake Fault zones in Moorpark and its
area of interest.
Oak Ridge Fault - The Oak Ridge fault extends from the Santa Susana
Mountains westward, along the southern margin of the Santa Clara Valley,
across the Oxnard Plain, and into the Santa Barbara Channel. Like the San
Andreas, the Oak Ridge fault has been divided into segments, the closest of
which is about 3 miles (5 km) away from the northern part of Moorpark. Although
the fault is considered to be a significant seismic source, most of it has not been
assigned to an Alquist Priolo Earthquake Fault Zone. The magnitude 6.7
Northridge Earthquake of January 17, 1994 is believed to have occurred on the
eastern extension of the Oak Ridge fault, in the Santa Clarita area. Minor
landsliding and ridge -top shattering were observed in the hills above Moorpark as
a result of this earthquake.
San Cayetano Fault - The San Cayetano fault is one of the two deeply rooted,
north - dipping thrust faults that form the northern boundary of the Ventura basin.
At its closest point, this fault is approximately 5 miles (9km) from the City.
Several small earthquakes have been associated with this active fault.
Santa Susana Fault - The Santa Susana fault merges with the Oak Ridge fault
on the west and the San Fernando fault zone on the east. The fault is located
about 4 miles (6 km) east - northeast of the Moorpark area. This fault is estimated
capable of generating a magnitude 6.6 earthquake that would result in ground
accelerations ranging from about 0.29 g to 0.60 g.
2. Seismic- related Hazards
Local geologic conditions can create additional hazards associated with seismic
activity. Unstable soils on steep slopes may fail under the stress of a tremor. In
(' locations where high groundwater levels interact with loose, unconsolidated soils,

GEOLOGIC AND SEISMIC HAZARDS
r, a condition called liquefaction can occur, whereby such soils lose cohesion —
and their ability to support structures — when subjected to strong ground motion.
Strong ground shaking of relatively long duration can be expected to occur in the
Moorpark area as a result of an earthquake on any of the several active faults in
the region. Loose, recently deposited sediments consisting primarily of silty sand
and sand occur in a large portion of the valley floors and in the larger canyon
bottoms. Water - saturated within about 50 feet of the surface have historically
been present in the lowlands of Moorpark, including the Little Simi Valley, the
Tierra Rejada Valley, and the elevated valley traversed by Broadway Street.
Under certain conditions, strong ground shaking can cause the densdication of
soils, resulting in local or regional settlement of the ground surface. Those
portions of the Moorpark Area that may be susceptible to seismically induced
settlement are generally the floodplains and larger drainages that are underlain
by late Quaternary alluvial sediments (similar to the liquefaction - susceptible
areas). Sites near the base of natural hills (valley margins) may be particularly
vulnerable.
The hilly and mountainous areas of Moorpark are underlain by soft sedimentary
bedrock. Earthquake- induced landslides could also impact developments
adjacent to the mountain front the northern portion of Moorpark would be most
vulnerable to seismically induced slope failure, due to the steep terrain and the
presence of weak sedimentery rock units. Slopes adjacent to or within
developments should be evaluated for these geologic conditions. Figure 4 -2
shows areas mapped by the state as having a potential for liquefaction
susceptibility and seismically induced landsliding.
Goals and Policies
Goal 1.0
Minimize the potential damage to structures and loss of life that could result from
earthquakes.
Policy 1.1: Continue to implement Uniform Building Code seismic safety
standards for construction of new buildings, and update the City's
codes as needed in response to new information and standards
developed at the State level.
Policy 1.2 Require the preparation of detailed geologic studies for any
development proposal within seismic hazard zones and liquefaction
hazard areas.
Policy 1.3: Perform a building inventory to locate, count, and identify buildings by
structural type and occupancy.
Policy 1.4: When modifications to existing older buildings are proposed,
determine whether an engineering evaluation is required to identify

seismic retrofit needs. Require that corrections be made to buildings
deemed unsafe.
Policy 1.5: Encourage residential property owners to implement seismic safety
improvements in older buildings, such as anchoring buildings to
foundations, bolting water heaters to walls, and performing other
preventative measures.
Policy 1.6: Participate in local, county, and State - sponsored earthquake
preparedness programs.
Policy 1.7: Continue to monitor groundwater levels in all potential liquefaction
areas. If the water levels reach within 40 feet of the surface, the City
Engineer shall require appropriate mitigation to alleviate the hazard to
large structures as necessary.
Goal 2.0
Ensure that all residents and business owners in Moorpark have full and equal
access to information regarding seismic hazards.
PolicyZl: Promote earthquake preparedness with publications available in the
predominant languages spoken in the community.
Policy 2.2. Provide earthquake preparedness information at City - sponsored
events.
C. Geologic Hazards
The following describes the non - seismic geologic hazards affecting Moorpark.
1. Landslides
Landslides are movement of relatively large landmasses, either as a nearly intact
bedrock blocks or as jumbled mixes of bedrock blocks, fragments, debris, and soils.
Considering the abundance of hillside terrain, the occurrence of landslides in
Moorpark is notably infrequent as shown in Figure 4 -3. Landsliding has occurred in
isolated locations throughout the area. These locations include the mid reach of the
Gabbert Canyon stream, a large slide complex present south of the Arroyo Las
Poses, the south flank of Big Mountain, the Arroyo Simi, and the Las Posas Hills
northeast of the Tierra Rejada Valley in the vicinity of the Simi -Santa Rosa fault
zone.
2. Debris Flow
A debris flow (also called mudflow, mudslide, or debris avalanche) is a rapidly
moving slurry of water, mud, rock, vegetation, and debris. Failure occurs during an
intense rainfall event, following saturation of the soil from previous rains. Hazard

mapping by the California Division of Mines and Geology placed most of the hillsides
in Moorpark in a high mudslide risk zone, as well as unincorporated properties to the
City's west and southeast. Most of the hillside areas have been reclassified as
"marginally susceptible" to debris flow. Localized areas have been classified as
"most susceptible" based on relatively common evidence for past debris flow. City
review of development proposals includes consideration of debris flow.
3. Expansive Soils
Fine - grained soils such as silts and clays may contain variable amounts of expansive
clay minerals. These minerals can expand when wetted and contract when dried.
The upward pressures induced by the swelling of expansive soils can have
significant harmful effects upon structures and other surface improvements.
Sedimentary units that are composed primarily of granular soils underlie most of
Moorpark. Such units are typically in the low to moderately -low range for expansion
potential. However, every such sedimentary unit contains lenses or layers of finer -
grained soils (clays and silty clays) that typically are in the moderate to highly
expansive range. Potentially expansive layers may be exposed at the surface by
erosion or may be uncovered by grading cuts made for developments. Procedures
that provide safe designs for expansive soils are incorporated in the Building and
Safety Department and the City Engineer review process.
4. Ground Subsidence
Ground subsidence is the gradual settling or sinking of the ground surface with little
or no horizontal movement. In the areas of Southern California where significant
ground subsidence has been reported, this phenomenon is usually associated with
the extraction of oil, gas, or groundwater from below the ground surface. Historically,
no regional subsidence has been reported for the Moorpark area. However, the thick
alluvial deposits underlying Little Simi Valley and Tierra Rejada Valley may be
susceptible to subsidence should rapid groundwater withdrawl occur beneath the
area in response to an increasing population. Possible measures to manage
subsidence include increased use of reclaimed water, storm water, and imported
water; protection of groundwater quality; and determining the safe yields of
groundwater basins so that the available supplies can be balanced with groundwater
extraction.
Goals and Policies
Goal 3.0

HAZARDOUS MATERIALS AND WASTES
5. HAZARDOUS MATERIALS AND WASTES
In Moorpark, commercial and industrial businesses that use hazardous materials'
include dry cleaners, film processors, auto service providers, landscape contractors,
among many others. Residences also generate household hazardous wastes in the
form of paints, thinners, pesticides, fertilizers, etc. Hazardous waste generators and
users are required to comply with regulations enforced by several federal, state, and
county agencies. The regulations aim toward reducing risk associated with human
exposure to hazardous materials and minimizing adverse environmental effects.
The Fire Protection District for the County of Ventura functions as part of the City
Government, similar to other departments within the City. The County Fire
Protection District coordinates hazardous material and disaster preparedness
planning and appropriate response efforts with City departments, as well as local and
state agencies. Businesses within Moorpark that handle hazardous materials submit
a business plan, including a chemical inventory, to the County Fire Protection
District.
Despite all efforts to guard against health risks associated with hazardous materials,
such materials can be released accidentally into the environment as a result of a
natural disaster or improper storage and handling. The City's Standardized
Emergency Management System (SEMS) Multihazard Functional Plan prepares City
staff to react quickly and specifically to any hazardous materials accident. The
SEMS designates Ventura County as the administering agency for hazardous
�- materials in the City.
To address proper handling and disposal of household hazardous wastes, the City
has adopted a Household Hazardous Waste (HHW) Element in accordance with the
California Integrated Solid Waste Management Act of 1989. HHW drop -off facilities
located in Thousand Oaks and Simi Valley are staffed by contracted personnel and
are free to Moorpark residents.
Goals and policies
Goal 4.0
Protect residents and business employees from potential hazards associated with
the use, storage, manufacture, and transportation of hazardous materials in and
through the City.
Policy 4.1: Continue to participate in the Standardized Emergency Management
System and the Ventura County Stormwater Program [local enforcer
of the National Pollutant Discharge Elimination System (NPDES)
program].
Policy 4.2: Educate the community regarding the proper storage, handling, use,
and disposal of hazardous household materials.
r The California Health and Safety Code defines a hazardous material as any material that, because of its quantity, concentration,
or physical or chemical characteristics, poses a significant potential hazard to human health and safety or to the environment.

FLOODING
(1- 6. FLOODING
N
A. Historic Flood Flows
Moorpark is drained by a system of streams that are part of the Calleguas Creek
watershed. Calleguas Creek is locally referred to as Arroyo Simi (to the west, from
Hitch Boulevard to Somis, it is called Arroyo Las Poses). The Arroyo Simi originates
in the Santa Susana Mountains and drains an area of approximately 112 square
miles at the confluence with Happy Camp Canyon.
Three types of storms produce precipitation in Ventura County: winter storms, local
thunderstorms, and summer tropical storms. Winter storms are characterized by
heavy and sometimes prolonged precipitation over a large area. Local thunderstorms
can occur at any time, but usually cover relatively small areas. These storms are
usually prevalent in the higher mountains during the summer. Tropical rains are
infrequent, but typically occur in the summer or early fall. Yearly precipitation in the
Moorpark area averages 14 inches. However, rainfall is extremely variable from year
to year, ranging from one -third the normal amount to more than double the normal
amount. This unpredictable seasonal range in rainfall, coupled with geographic and
geologic conditions, makes Moorpark extremely vulnerable to flooding, erosion, and
mudf lows during the winter storm season.
The City participates in the National Flood Insurance Program. Figure 6 -1 indicates
those areas of the City and within the sphere of influence subjected to flooding.
Most of the Little Simi Valley along and north of the Arroyo Simi is included in the
500 -year floodplain. Within this area are several critical facilities, including a
Southern California Edison Substation, the Police Service Center, Post Office,
Chapparel Middle School, and Flory School. Arroyo West School is situated at the
edge of the 100 -year floodplain for Peach Hill Wash, and the Amtrak Station is
situated at the edge of the 500 -year floodplain for the Arroyo Simi. The Moorpark
Water Treatment Plant lies within the 500 -year flood boundary of Arroyo Las Posas.
In addition, numerous sites containing hazardous materials are within the 500 -year
flood boundary in Little Simi Valley, and several are at the edge of the 100 -year
boundary for the Arroyo Simi.
B. Inundation
One major dam, the Wood Ranch Reservoir, is located upstream from the Moorpark
Area within the Arroyo Simi. This dam is owned by the Calleguas Municipal Water
District. The earth -fill dam was built in 1965, is 146 feet (45m) high, and 24 feet (7m)
wide. The flood inundation plan, should the dam fail, is shown in Figure 6 -2. The
figure indicates that a large portion of Little Simi Valley would be flooded.
Other smaller flood control improvements, such as canals, culverts, and retention
basins may crack and suffer some structural damage during an earthquake,
especially in areas prone to ground failure. Seismically induced inundation can also
occur if strong ground shaking causes structural damage to above - groundwater

C. Flood Protection Measures
Previous flood disasters caused an increased awareness of the potential for public
and private losses, particularly in the highly urbanized parts of floodplains and
alluvial fans. Flooding in the area is difficult to predict and plan for because rainfall in
the area is extremely variable. Floods that impact the City are typically of short
duration, high peak volumes and high velocity.
The Ventura County Flood Control District has jurisdiction over the watercourses in
the Moorpark area, as well as the regional flood control system in the county. An
extensive municipal storm drain network operated by the City provides flood
protection for urbanized areas. While these flood control structures have provided
significant protection from uncontrolled flooding, additional protection is needed.
Outside of the Little Simi Valley and nearby hills, undeveloped and agricultural lands
are slated for long -term development.
Goals and Policies
Goal 5.0
Reduce the risk to the community from hazards related flooding.
Policy 5.1: Continue to participate in the National Flood Insurance Program.
Policy 5.2: Ensure that future projects include mitigation for hydrological impacts.
Mitigation can include catch basins, stormwater pipelines, and
detention basins.
Policy 5.3: Consider floodway management design that includes areas where
stream courses are left natural or as developed open space.
Policy 5.4: Improve flood control structures, including modification of the Walnut
Canyon and Gabbert Canyon debris basins, addition of new detention
basins, channel reconstruction, and diversion systems.
Policy 5.5.- Encourage property owners with buildings located within a Special
Flood Hazard Area to have all components of the property's electrical
system raised at least one foot above the 100 -year flood level.

FIRE HAZARDS
7. FIRE HAZARDS
Fire hazards of concern in the City are those associated with structures and brush, as
well as earthquake- induced fires. The Ventura County Fire Protection District (also
known as the Ventura County Fire Department) provides contract fire protection services
to the City. Fire potential for the Moorpark region is typically greatest in the months of
August, September, and October, when dry vegetation, combined with offshore dry
Santa Ana winds, create a high potential for spontaneous fires. The hillsides and steep
slopes facilitate rapid fire spread. Figure 7 -1 shows fire susceptibility in the Moorpark
area.
A. Wildland Fires
The Ventura County Fire Protection District has responsibility for wildfire
suppression. The undeveloped hills in the City and surrounding sphere of influence
area are rated as a potential wildland fire area by the State of California Department
of Forestry and Fire Prevention. In these areas, special state statutes govern
development and the maintenance requirements of property owners. Figure 7 -1
shows wildland areas and very high fire hazard severity zones.
To help minimize the impact of fire
requirements for structures located
include approved materials for roof
spaces, and patio covers.
B. Fire Prevention
in these zones, Ventura County has included
in high hazard regions. These requirements
and exterior wall coverings, decks, underfloor
Two stations located within the City limits — the Mountain Meadows Station (No. 40)
at 4185 Cedar Springs Street and the Moorpark Station (No. 42) within the
Downtown Specific Plan Area — provide direct response to incidents in the City. For
larger scale incidents, companies from stations in surrounding jurisdictions may
respond as well.
The County of Ventura administers the Uniform Fire Code (UFC) and the Uniform
Building Code (UBC) by updating the Ventura County Fire Protection Ordinance.
This ordinance is updated every four years to incorporate the most recent versions of
the UFC and UBC. The UFC includes requirements for minimum fire -flow rates for
water mains. The requirements are a function of building size, type, material,
purpose, location, proximity to other structures, and the type of fire suppression
systems installed. The various water districts in the County are required to test fire
protection capability for the various land uses per the flow requirements of the UFC.

EMERGENCY PREPAREDNESS
�., 8. EMERGENCY PREPAREDNESS
Major emergencies occur periodically in all communities. Proper emergency planning is
an essential action to minimize the disruption, personal injury, and property damage
associated with such events. Preventative measures and preparatory responses before
an emergency occurs will hasten recovery.
A. Earthquake Preparedness
Following an earthquake, the ability of roads and critical facilities to support response
and recovery operations affects the ultimate level of upset. Critical facilities are
those parts of the infrastructure that must remain operational to provide shelter,
medical services, law enforcement, fire protection, and similar public safety
functions. Critical facilities include schools, hospitals, fire and police stations,
emergency operation centers, and communication centers. Figure 8 -1 illustrates the
locations of Moorpark's fire stations, police stations, schools, and other essential
facilities in relation to local seismic hazards.
Lifelines are those services critical to the health, safety, and functioning of the
community, and are particularly essential for emergency response and recovery after
an earthquake. Lifeline systems include water, sewage, electrical power,
communication, transportation, natural gas, and liquid fuel systems.
In Moorpark, several critical facilities and lifeline systems are located within the 100 -
and 500 -year floodplain (see Section 6, Flooding of this element). These include the
Southern California Edison Substation, the Amtrak Station, the Moorpark Water
Treatment Plant, Police Service Center, Post Office, Chapparel Middle School, and
Arroyo West School.
B. Hazardous Materials Preparedness
As discussed in Section 5 of this Safety Element, several programs are in place to
reduce the risks of hazardous materials, including a Household Hazardous Waste
Element and regulations set forth by the Ventura County Fire Protection District. The
Moorpark Administrative Services Department has included an Emergency
Management Plan to enhance the City's Multihazard Functional Plan. Moorpark
participates in a County -wide interagency coalition to better utilize the expertise and
equipment that exists within all participating fire departments. The County of Ventura
coalition is considered a full- service Hazardous Materials Division.
C. Fire Preparedness
Section 7 of this Element outlined the fire hazards within Moorpark and programs for
fire prevention and suppression. Each Spring, the Ventura County Fire Protection
District inspects properties and notifies owners of fire hazards and compliance
requirements. The Ventura County Sheriff's Department Office of Emergency
Services provides public information on emergency response notification,
evacuation, and sheltering due to fire.
