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. City of Moorpark 1 -1 Safety Element 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 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. City of Moorpark 3 -1 Safety Element r f 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.

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 City of Moorpark 4 -4 Safety Element Liquefaction source: Areas where historic occurrence of liquefaction, or local geological, geotechnical and groundwater conditions indicated a potential for permanent ground displacements such that mitigation, as defined in Public Resources Code Section 2693c, would be required.

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 City of Moorpark 4 -6 Safety Element r" _ 9 O Z3 I s .

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 Protect public and private properties from geologic hazards associated with steep slopes, unstable hillsides, and subsidence. Policy 3.1: Reduce the risk of impacts from geologic hazards by applying proper engineering, building construction, and retrofitting requirements to the development process. City of Moorpark 4 -8 Safety Element GEOLOGIC AND SEISMIC HAZARDS f, Policy 3.2: Require that slope stability analyses be conducted for new development in hillside areas. Policy 3.3: Require that hillside developments incorporate measures that mitigate slope failure potential and provide for long -term slope maintenance. Policy 3.4: Participate in regional measures aimed at reducing the risk of subsidence throughout the City of Moorpark, the sphere of influence, and area of interest. City of Moorpark 4 -8 Safety Element 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. City of Moorpark 5 -1 Safety Element e HAZARDOUS MATERIALS AND WASTES Policy 4.3. Require business owners to incorporate into their business plans submitted to the County Fire Protection District those measures necessary to minimize hazardous materials accidents due to intense ground shaking potential and flooding Policy 4.4: Continue to participate in the County -wide interagency coalition to better utilize the expertise and equipment that exists within all participating fire departments. City of Moorpark 5 -4 Safety Element 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 City of Moorpark 6 -1 Safety Element N Thousand Oaks _ Areas within 100 -year flood zone ® Areas with a less severe risk of flooding (between 100- and 500 -year flood zones, flooding with average depths of less than one foot, contributing drainage area is less than one square mile, and /or protected by levee from the 100 -year flood) City Boundary Area of Interest PSA Dr. SimiI Source: Earth Consultants International; FEMA, 1985o,b,c,d,e; 1986b; 1990; and 1998 Figure 6 -1 North a 11 s miles FIRM Flood Zones City of Moorpark 6 -2 Safety Element M > %/o i. rs %� IMI ro m -0 ® Dom or Reservoir Failure Inundation Path R -X • Water Reservoir (tank) City Boundary Area of Interest Nom 0 1 City of Moorpark Y miles 6 -3 Source: Earth Consultants International; Ventura County Waterworks District No. 1 Figum 6-2 Dam Inundation • Res • • e Safety Element ("— tr FLOODING tanks. Figure 6 -2 shows above - ground tank locations in the City, its sphere of influence, and area of interest. 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. city of Moorpark 6 -4 Safety Element 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.

Key provisions include the following clearance requirements: • Clearance around structures shall be not less than 100 feet. • Single specimens of trees, ornamental shrubbery, or ground covers are permissible, provided they do not form a means of rapidly transmitting fire from the native growth to any structure. Such specimens shall be spaced a minimum of 15 feet from other specimens, structures, or surrounding native brush. ■ Roof surfaces shall be maintained free of accumulations of leaves, needles, twigs, or any other combustible materials. • Clearance should be 10 feet around propane tanks. • Access roads shall be maintained with a minimum 10 -foot clearance on each side of the traveled section. • Large vacant parcels located in Hazardous Watershed Fire Areas bordering on developed areas (urban /wildland interface) shall have a 100 -foot fuel break cleared along the entire interface border. Goals and Policies Goal 6.0 Reduce the risk to the community from hazards related to wildfires and structural fires. Policy 6.1: Continue to implement the fire hazard reduction goals and policies set forth in the Ventura County General Plan. Policy 6.2: Develop education and mitigation strategies that focus on enhanced hazards in the months of August, September, and October, when dry vegetation and Santa Ana winds coexist. Policy 6.3: Continue to require noncombustible roofing materials for new or replacement roofing. City of Moorpark 7 -3 Safety Element FIRE HAZARDS Policy 6.4: Continue a public education through the County Fire Protection i^ District's Community Education /Public Information Division to inform residents as to how they can help reduce fire hazards. City of Moorpark 7 -4 Safety Element 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.

Emergency Services EMERGENCY PREPAREDNESS Moorpark has developed an Emergency Services Program to maintain a responsible level of emergency preparedness in the City. The program includes the following components. • City staff receives training in emergency preparedness, management, and mitigation. • The City maintains an Emergency Operations Center. • The City Organizes and trains a Disaster Assistant Response Team (DART) comprised of Moorpark resident volunteers. • The City promotes emergency planning, training, public awareness, and education for emergency preparedness. Goals and Policies Goal 7.0 Improve the ability of the City to respond effectively to natural and human - caused emergencies. Policy 7.1: Continue the development of local preparedness plans and multi - jurisdictional cooperation and communication for emergency situations. Policy 7.2: Educate residents and businesses regarding appropriate actions to safeguard life and property during and immediately after emergencies. Policy 7.3: Develop flood warning systems and evacuation plans for those portions of the 100- and 500 -year flood zones that have already been developed (especially important for areas near the Arroyo Simi and for existing critical facilities and lifeline systems). Policy 7.4: Ensure that new critical facilities are not permitted in floodplains unless they are elevated above the projected inundation depths and/or otherwise protected.
