CC - Item 5C - Adoption of Rosemead Natural Hazard Mitigation Plan
TO: THE HONORABLE MAYOR AND CITY COUNCIL FROM: GLORIA MOLLEDA, CITY MANAGER Ojv DATE: OCTOBER 23, 2018 SUBJECT: ADOPTION OF RESOLUTION NO, 2018-63 APPROVING THE CITY OF ROSEMEAD NATURAL HAZARD MITIGATION PLAN SUMMARY The federal Disaster Management Act of 2000 (DMA 2000), which amended the Robert T. Stafford Disaster Relief and Emergency Assistance Act, requires every local, county and state government to have an approved Hazard Mitigation Plan. In addition to minimizing the impact of major hazard events on the community, completion of the Plan also maintains eligibility for future hazard mitigation funding following any significant disasters. As a result of the DMA 2000 legislation, hazard mitigation is now considered to be the first step in preparing for emergencies, rather than the final step in recovery. The consequences of not having an approved Hazard Mitigation Plan are significant. Without one, the City will be ineligible for FEMA mitigation programs including the Hazard Mitigation Grant Program, Flood Mitigation Assistance Program, and most importantly, the potential loss of public assistance for damaged facilities following a disaster. As an example, the County of Los Angeles received approximately $500 million in FEMA mitigation money following the 1994 Northridge Earthquake. Development of the Plan is in accordance with Strategy 6 of the City's Strategic Plan ("Increase the City's level of Emergency Preparedness") and corresponding action items. STAFF RECOMMENDATION It is recommended that the City Council Adopt the City of Rosemead Local Hazard Mitigation Plan ("Plan") and adopt City Council Resolution No. 2018-63. Adoption legitimizes the plan and authorizes departments and their staffs to executive their responsibilities. The 2018 Plan is an update to the Council -adopted 2012 Plan. AGENDA ITEM NO. 5.0 City Council Meeting October 23, 2018 Page 2 of 3 ANALYSIS Emergency Planning Consultants was contracted to assist the City in drafting the Plan. A Planning Team was formed consisting of representatives from Parks & Recreation, City Clerk's Office, Public Works, Community Development, Human Resources, Finance, Administration, and Public Safety. The Team met a total of three times to examine hazards and impacts, update and develop mitigation actions, develop a strategy for public input, and review the First Draft Plan. Information required for the Hazard Mitigation Plan was drawn from a variety of sources including the Los Angeles County All -Hazards Mitigation Plan. As mentioned above, it was important to provide an opportunity for the general public as well as interested external agencies (e.g. adjoining jurisdictions, special districts, etc.) to participate in the planning process. This was accomplished through posting of the Second Draft Plan and distribution of invitations via the City's website and invitational emails. Tonight's meeting is another critical component of the planning process as another opportunity for participation by the public and stakeholders. Tonight's meeting was announced on the City's website and other routine postings. PLAN STRUCTURE The Hazard Mitigation Plan documents the mitigation planning process including how it was developed, the planning timeframe, and who was involved in drafting the document. A risk assessment was conducted and details the type of natural hazards that can affect the jurisdiction. The Plan also includes information on previous occurrences of hazard events and the probability of future events. The City's essential and critical facilities were assessed as to vulnerability. Demographic and land use data was also important in identifying present day and future vulnerabilities. The core of the Plan is the Mitigation Strategy which outlines the City's blueprint for reducing the potential losses identified in the risk assessment, based on existing authorities, policies, programs, and resources, and its ability to expand on and improve these existing tools. FINDINGS The Plan identifies a broad range of mitigation action items, including assigned departments, timelines, and priorities. The mitigation action items are aimed at activities that will minimize or eliminate the impact of hazards on the community and its vital resources. City Council Meeting October 23, 2018 Page 3 of 3 The Third Draft Plan was submitted to Cal OES for input and forwarding to FEMA Region IX for a determination of Approval Pending Adoption. The City Council is requested to adopt the Final Draft Plan, Proof of the Council's adoption will be forwarded to FEMA along with a request for a Notice of Final Approval. RECOMMENDATIONS Staff recommends that the City Council adopt the 2018 Hazard Mitigation Plan. PUBLIC NOTICE PROCESS This item has been noticed through the regular agenda notification process. FISCAL IMPACT There is no direct fiscal impact as a result of adopting the proposed Plan, however, such adoption and subsequent submittal to Federal Emergency Management Agency (FEMA) is a prerequisite for receiving any future disaster relief or mitigation funds.

Q: Does the plan list thejurisdiction(s) participating in the plan that are seeking approval? (Requirement §201.6(c)(1)) A: See Introduction below. The Hazard Mitigation Plan (Mitigation Plan) was prepared in response to Disaster Mitigation Act of 2000 (DMA 2000). DMA 2000 (also known as Public Law 106-390) requires state and local governments to prepare mitigation plans to document their mitigation planning process, and identify hazards, potential losses, mitigation needs, goals, and strategies. This type of planning supplements the City's comprehensive land use planning and emergency management planning programs. This document is a federally mandated update to the City of Rosemead 2012 Hazard Mitigation Plan and ensures continuing eligibility for Hazard Mitigation Grant Program (HMGP) funding. DMA 2000 was designed to establish a national program for pre -disaster mitigation, streamline disaster relief at the federal and state levels, and control federal disaster assistance costs. Congress believed these requirements would produce the following benefits: • Reduce loss of life and property, human suffering, economic disruption, and disaster costs. • Prioritize hazard mitigation at the local level with increased emphasis on planning and public involvement, assessing risks, implementing loss reduction measures, and ensuring critical facilities/services survive a disaster. • Promote education and economic incentives to form community-based partnerships and leverage non-federal resources to commit to and implement long-term hazard mitigation activities. The following FEMA definitions are used throughout this plan (Source: FEMA, 2002, Getting Started, Building Support for Mitigation Planning, FEMA 386-1): Hazard Mitigation — "Any sustained action taken to reduce or eliminate the long-term risk to human: life and property from hazards". Planning — "The act or process of making or carrying out plans; specifically, the establishment of goals, policies, and procedures for a social or economic unit."' Planni : ngApproach The four -step planning approach outlined in the FEMA publication, Developing the Mitigation Plan: Identifying Mitigation Actions and Implementing Strategies (FEMA 386-3) was used to develop this plan: a Hazard Mitigation Plan 12018 IntroductiO17 Is- OSE • Develop mitigation goals and objectives - The risk assessment (hazard characteristics, inventory, and findings), along with municipal policy documents, were utilized to develop mitigation goals and objectives. • Identify and prioritize mitigation actions - used on the risk assessment, goals and objectives, existing lite ratu re/resou rces, and input from participating entities, mitigation activities were identified for each hazard. Activities were 1) qualitatively evaluated against the goals and objectives, and other criteria; 2) identified as high, medium, or low priority; and 3) presented in a series of hazard -specific tables. • Prepare implementation strategy - Generally, high priority activities are recommended for implementation first. However, based on community needs and goals, project costs, and available funding, some medium or low priority activities may be implemented before some high priority items. • Document mitigation planning process - The mitigation planning process is documented throughout this plan. Huard Land Use Policy In Callfownia Planning for hazards should be an integral element of any City's land use planning program. All California cities and counties have General Plans (also known as Comprehensive Plans) and the implementing ordinances that are required to comply with the statewide land use planning regulations. The continuing challenge faced by local officials and state government is to keep the network of local plans effective in responding to the changing conditions and needs of California's diverse communities, particularly in light of the very active seismic region in which we live. Planning for hazards requires a thorough understanding of the various hazards facing the City and region as a whole. Additionally, it's important to take an inventory of the structures and contents of various City holdings. These inventories should include the compendium of hazards facing the City, the built environment at risk, the personal property that may be damaged by hazard events and most of all, the people who live in the shadow of these hazards. Such an analysis is found in this hazard mitigation plan. State and Federal Partners In Hazard Mitigation All mitigation is local and the primary responsibility for development and implementation of risk reduction strategies and policies lies with each local jurisdiction. Local jurisdictions, however, are not alone. Partners and resources exist at the regional, state and federal levels. Numerous California state agencies have a role in hazards and hazard mitigation. Some of the key agencies include: • California Office of Emergency Services (Cal OES) is responsible for disaster mitigation, preparedness, response, recovery, and the administration of federal funds after a major disaster declaration; • Southern California Earthquake Center (SCEC) gathers information about earthquakes, integrates information on earthquake phenomena, and communicates this to end-users and the general public to increase earthquake awareness, reduce economic losses, and save lives. Hazard Mitigation Plan 1 2018 Intruduction MR ✓ California Department of Forestry and Fire Protection (CAL FIRE) is responsible for all aspects of wildland fire protection on private and state properties, and administers forest practices regulations, including landslide mitigation, on non-federal lands. ✓ California Division of Mines and Geology (DMG) is responsible for geologic hazard characterization, public education, and the development of partnerships aimed at reducing risk. • California Division of Water Resources (DWR) plans, designs, constructs, operates, and maintains the State Water Project; regulates dams; provides flood protection and assists in emergency management. It also educates the public, serves local water needs by providing technical assistance • FEMA provides hazard mitigation guidance, resource materials, and educational materials to support implementation of the capitalizedDMA 2000. • United States Census Bureau (USCB), provides demographic data on the populations affected by natural disasters. • United States Department of Agriculture (USDA) provides data on matters pertaining to land management. Q&A I ELEMENT A: PLANNING PROCESS I A3 Q. Does the Plan document how the public was involved in the planning process during the drafting stage? (Requirement §201.6(b)(1)) A: See Stakeholders below. Stakeholders A Hazard Mitigation Planning Team (Planning Team) consisting of department representatives from City of Rosemead staff worked with Emergency Planning Consultants to create the updated Plan. The Planning Team served as the primary stakeholders throughout the planning process. The general public, CONNECTIONS Forum, Business Watch Group, Rosemead Advanced CERT and HAM, Chamber of Commerce, City of Rosemead Emergency Communication Team (Co ECT), and external agencies served as secondary stakeholders with an opportunity to contribute to the plan during the Plan Writing Phase of the planning process. As required by DMA 2000, the Planning Team involved the "general public" by making the Second Draft Plan available online during the plan writing phase. I:n addition, Planning Team Mandy Wong provided a PowerPoint briefing on the Second Draft Plan during a monthly meeting of the City's CONNECTIONS Forum. The Public Safety Department's CONNECTIONS Forum is a group of community organizations and individuals, including the City of Rosemead, the Sheriffs Department, school districts, and faith -based organizations who are committed to educating parents, grandparents, and other caregivers of their responsibilities in helping young people avoid negative consequences associated with alcohol and drug use. The mission of CONNECTIONS is to: Serve as a community "think tank" and "information clearinghouse" to prevent crime and combat drugs and alcohol abuse; Develop and promote positive and wholesome recreational activities and community service opportunities for young people and their families; Hazard Mitigation Plan 12018 Introduction 4 R,(�JsE MEAD * Coordinate with organizations that address human and social services needs to promote a healthy community; and ® Promote and encourage emergency preparedness by all community members. The briefing to CONNECTIONS was conducted on January 25, 2018. Also, the Planning Team notified the Business Watch Group, Rosemead Advanced CERT and HAM members, and the Chamber of Commerce of the Draft's online availability. Lastly, external agencies (including utility providers, special districts and adjoining jurisdictions) were directed to the Second Draft Plan via an email invitation. The Second Draft Plan was announced and posted on the City's website on December 18, 2017 and again on February 23, 2018 along with a request to forward any comments to the Planning Team Chair Mandy Wong. A hard copy of the Second Draft Plan was available to the public at the Public Safety Department's reception counter. lNebsite Screenshots-- I-ebruary 23, 201 - Landling Page and Access to Plan 0 C) Q,, 11 WFLCONICs TO THE CITY OF ROSEMEAD TEMPORARY SITE.

Stafford Disaster Relief and Emergency Act, commonly referred to as the Stafford Act. In 1988, Congress established the Hazard Mitigation Grant Program (HMGP) via Section 404 of the Stafford Act. Regulations regarding HMGP implementation based on the DMA 2000 were initially changed by an Interim Final Rule (44 CFR Part 206, Subpart N) published in the Federal Register on February 26, 2002. A second Interim Final Rule was issued on October 1, 2002. The HMGP helps states and local governments implement long-term hazard mitigation measures for natural hazards by providing federal funding following a federal disaster declaration. Eligible applicants include state and local agencies, Indian tribes or other tribal organizations, and certain nonprofit organizations. In California, the HMGP is administered by Cal CES. Examples of typical HMGP projects include: • Property acquisition and relocation projects • Structural retrofitting to minimize damages from earthquake, flood, high wind, wildfire, or other natural hazards v/ Elevation of flood -prone structures V Vegetative management programs, such as: 1-Mi'm rnnergency plowl"ti ConBullonts Hazard Mitigation Plan 12018 Inti,oduction ISM • Brush control and maintenance • Fuel break lines in shrubbery • Fire-resistant vegetation in potential wildland fire areas Pre -Disaster Mifxgatioo Program The Pre -Disaster Mitigation Program (PDM) was authorized by §203 of the Stafford Act, 42 United States Code, as amended by §102 of the DMA 2000. Funding is provided through the National Pre -Disaster Mitigation Fund to help state and local governments (including tribal governments) implement cost-effective hazard mitigation activities that complement a comprehensive mitigation program. In Fiscal Year 2009, two types of grants (planning and competitive) were offered under the PDM Program. Planning grants allocate funds to each state for Mitigation Plan development. Competitive grants distribute funds to states, local governments, and federally recognized Indian tribal governments via a competitive application process. FEMA reviews and ranks the submittals based on pre -determined criteria. The minimum eligibility requirements for competitive grants include participation in good standing in the National Flood Insurance Program (NFIP) and a FEMA -approved Mitigation Plan. (Source: http://www.fema.gov/fima/pdm.shtm) Flood Mitcqation Assistance Program The Flood Mitigation Assistance (FMA) Program was created as part "Floods and hurricanes of the National Flood Insurance Reform Act (NFIRA) of 1994 (42 happen. The hazard itself U.S.C. 4101). Financial support is provided through the National is not the disaster - it's our Flood Insurance Fund to help states and communities implement measures to reduce or eliminate the long-term risk of flood damage habits, it's how we build to buildings, manufactured homes, and other structures insurable and live in those under the NFIP. areas ... that's the disaster." Three types of grants are available under FMA: planning, project, and technical assistance. Planning grants are available to states and communities to prepare Flood Mitigation Plans.

Technical assistance grants in the amount of 10 percent Of Administrator the project grant are available to the state for program administration. Communities that receive planning and/or project grants must participate in the NFIP. Examples of eligible projects include elevation, acquisition, and relocation of NFIP-insured structures. (Source: http://www.fema.gov/fima/fma.shtm) Q&A I ELEMENT C. MITIGATION STRATEGY I C2 Q: Does the Plan address each jurisdiction's participation in the NFIP and continued compliance i with NFIP requirements, as appropriate? (Requirement §201 6(c)(3)(ii)) A. See NFIP Participation below. ii Hazard Mitigation, Plan 12018 Introduction Elm I=— National Rood Insurance Program Established in 1968, the NFIP provides federally -backed flood insurance to homeowners, renters, and businesses in communities that adopt and enforce floodplain management ordinances to reduce future flood damage. The City of Rosemead adopted a floodplain management ordinance and has Flood Insurance Rate Maps (FIRM) that show floodways, 100 -year flood zones, and 500 year flood zones. The Community Development Director is designated as the floodplain administrator. The City will maintain its participation with NFIP by continuing to enforce the Zoning Ordinance. Enforcement takes place when a prospective developer submits a permit request or building plans and the Community Department staff member looks up the zoning on the property. If the property is located in or near a designated floodplain, the applicant is provided with an NFIP brochure. NFIP Participation The City of Rosemead participates in NFIP and the FEMA FIRM maps for the City of Rosemead were last updated September 26, 2008. These studies and maps represent flood risk at the point in time when FEMA completed the studies and does not incorporate planning for floodplain changes in the future due to new development. Although FEMA is considering changing that policy, it is optional for local communities. According to FEMA, the City of Rosemead is designated a No Special Flood Hazard Area (NSFHA). A Non -Special Flood Hazard Area (NSFHA) is an area that is in a moderate- to low-risk flood zone (Zones B, C, X Pre- and Post - FIRM). The City of Rosemead is located within flood Zones X and D. The NSFHA is not in any immediate danger from flooding caused by overflowing rivers or hard rains. However, it's important to note that structures within a NSFHA are still at risk. In fact, over 20% of all flood insurance claims come from areas outside of mapped high-risk flood zones. Q&A I ELEMENT B: HAZARD IDENTIFICATION AND RISK ASSESSMENT I B4 Q: Does the Plan address NFIP insured structures within thejurisdiction that have been repetitively damaged by floods? (Requirement §2011.6(c)(2)(ii)) A: See Repetitive Loss Properties below. Repetitive Loss Propedies Repetitive Loss Properties (RLPs) are most susceptible to flood damages; therefore, they have been the focus of flood hazard mitigation programs. Unlike a Countywide program, the Floodplain Management Plan (FMP) for repetitive loss properties involves highly diversified property profiles, drainage issues, and property owner's interest. It also requires public involvement processes unique to each RLP area. The objective of an FMP is to provide specific potential mitigation measures and activities to best address the problems and needs Of communities with repetitive loss properties. A repetitive loss property is one for which two or more claims of $1,000 or more have been paid by the National Flood' Insurance Program (NFIP) within any given ten-year period. According to FEMA resources, there are no Repetitive Loss Properties (RLPs) within the City of Rosemead. State and Federal Guidance In Hazard Mitigation ii Hazard Mitigation Plan 12018 Introdtiction (m, While local jurisdictions have primary responsibility for developing and implementing hazard mitigation strategies, they are not alone. Various state and federal partners and resources can help local agencies with mitigation planning. The Mitigation Plan was prepared in accordance with the following regulations and guidance documents: * DMA 2000 (Public Law 106-390, October 10, 2000) * 44 CFR Parts 201 and 206, Mitigation Planning and Hazard Mitigation Grant Program, Interim Final Rule, October 1, 2002 * 44 CFR Parts 201 and 206, Mitigation Planning and Hazard Mitigation Grant Program, Interim Final Rule, February 26, 2002 * How -To Guide for Using HAZUS-MH for Risk Assessment, (FEMA 433), February 2004 * Mitigation Planning "How-to" Series (FEMA 386-1 through 9 available at: http://www.fema.gov/fima/planhowto.shtm) * Getting Started: Building Support for Mitigation Planning (FEMA 386-1) * Understanding Your Risks: Identifying Hazards and Estimating Losses (FEMA 386-2) Developing the Mitigation Plan: Identifying Mitigation Actions and Implementing Strategies (FEMA 386-3) V Bringing the Plan to Life: Implementing the Mitigation Plan (FEMA 386-4) Using Benefit -Cost Review in Mitigation Planning (FEMA 386-5) ✓ Integrating Historic Property and Cultural Resource Considerations into Mitigation Planning (FEMA 386-6) • Integrating Manmade Hazards into Mitigation Planning (FEMA 386-7) • Multi -Jurisdictional Mitigation Planning (FEMA 386-8) ✓ Using the Mitigation Plan to Prepare Successful Mitigation Projects (FEMA 386-9) • State and Local Plan Interim Criteria Under the DMA 2000, July 11, 2002, FEMA • Mitigation Planning Workshop for Local Governments -Instructor Guide, July 2002, FEMA • Report on Costs and Benefits of Natural Hazard Mitigation, Document #294, FEMA • LHMP Development Guide — Appendix A - Resource, Document, and Tool List for Local Mitigation Planning, December 2, 2003, Cal OES Local Mitigation Plan Review Guide (FEMA 2011) V Local Mitigation Planning Handbook (FEMA 2013) How is the Plan 0irganized?

Next, following any necessary revisions, a Second Draft Plan was shared with the secondary stakeholders - general public, local community groups, and external agencies (utilities, special districts, adjoining jurisdictions) during the plan writing phase. The comments gathered from the secondary stakeholders were incorporated into a Third Draft Plan which was submitted to Cal CES and, FEMA. Next, the Planning Team completed any mandated amendments to satisfy input from Cal OES and FEMA. Following receipt of FEMA's "Approval Pending Adoption", the Final Draft Plan was posted as per jurisdictional practices in advance of the City Council meeting. Any questions or comments gathered in advance of the City Council meeting were incorporated into the City Council Staff Report. Following consideration and adoption by the City Council, proof of the Plan's adoption was forwarded to FEMA along with a request for final approval.

Hazard Mitigation Plan 12018 Planning Process -37- Part 11: RISK ASSESSMENT Community Profile Geography and the Environment According to the City of Rosemead's General Plan (2010), the City is approximately 5.2 square miles in size and located in the San Gabriel Valley, approximately 11 miles east of downtown Los Angeles. Rosemead has easy accessibility to several freeways that connect it to the City of Los Angeles and the larger Los Angeles metropolitan region. The San Bernardino Freeway (Interstate 10) runs east -west through the City, and the Pomona Freeway (State Route 60) runs through the southern portion. Interstate 710 to the west provides direct access to Long Beach, and Interstate 605 to the east connects to Huntington Beach. Interstate 210 to the north provides east -west connection to the San Fernando Valley and the Inland Empire. =I, According to the National Weather Service, the City has a moderate climate, including dry summers with an average temperature of about 71'F and cool, wet winters with an average temperature of 58°F. The average annual rainfall for the region is between 14-18 inches. As the State of California and the Los Angeles region has undergone a several -year drought, rainfall has been much lower in the City. However, rainfall totals should increase as the City is expected to be in an El Nifio year for 2017. Furthermore, actual rainfall in the Southern California region tends to fall in large amounts during sporadic and often heavy storms rather than consistently over storms at somewhat regular intervals. In short rainfall in Southern California might be characterized as feast or famine within a single year. Population and Demographics According to the City's General Plan, the City was incorporated in 1959 with a population of 15,476. According to the California Department of Finance (2017), the population has grown to 54,984 as of 2017. From 2000 to 2017, the City has experienced an average growth rate of 0.13 percent annually. Similarly, the population of Los Angeles County experienced a growth rate of 0.4 percent per year. Despite being home to Southern California Edison, the City has experienced relatively slow economic growth. According to the California Department of Finance (2015), the demographic makeup of the City is as follows: Hazard Mitigation Plan 12018 CommuffitY Proffle selm Table.

The 1-10 and SR -60 freeways are both east -west trending facilities within the City that have access ramps at major north -south roadways. These freeways link Rosemead residents and businesses to destinations throughout the Los Angeles area and the Southern California region. Rosemead Boulevard, Walnut Grove Avenue, San Gabriel Boulevard, and Del Mar Avenue are the major north -south roadways within the City.All four -major north -south roads provide connections to Interstate 10. In addition, San Gabriel Boulevard connects to SR -60 within the southern area of the city. Valley Boulevard, Garvey Avenue, Graves Avenue, and Rush Street are the major east -west roadways within the City. Although these arterials often act as relief valves to the freeways during peak commute periods, they also provide good alternative travel routes to destinations throughout the San Gabriel Valley. Rosemead is served by a basic network of regional transit lines and the local shuttle lines operated by the City. Fixed route transit is provided by the Metropolitan Transit Authority.

Maps are used in this plan to display hazard identification data. The City of Rosemead utilized the categorization of hazards as identified in California's State Hazard Mitigation Plan, including: Earthquakes, Floods, Levee Failures, Wildfires, Landslides and Earth Movements, Tsunami, Climate -related hazards, Volcanoes, and Other Hazards (including Drought). Next, the Planning Team reviewed existing documents to determine which of these hazards posed the most significant threat to the City. In other words, which hazard would likely result in a local declaration of emergency. a Cal OFS GFNERAL PLAN UPRATE 0=1 =UIP, "IraLl RisA Assessmeot SHE 001 KOISE EAD (15� The geographic extent of each of the identified hazards was identified by the Planning Team utilizing maps and data contained in the City's General. In addition, numerous internet resources and the County of Los Angeles All -Hazards Mitigation Plan served as valuable resources. Utilizing the Calculated Priority Risk Index (CPRI) ranking technique, the Planning Team concluded the following hazards posed a significant threat against the City: The hazard ranking system is described in Table: Calculated Priority Risk Index, while the actual ranking is shown in Table: Calculated Priority Risk Index Ranking for City of Rosemead. .11 Hazard Mitigation Plan 12018 Risk Assessment Irm I LO cm FL .2 C14 CIO z3- m Q3 U) O 2 4) 2 co U) cn m m 70 :t-_ CD 0 cn AD Cl7 C6 V) 0 (D 0 0 C6 753 2 L) U) En 0 C15 0 (D co ocm -0 CD LD cn _0 L) >O N 42 U5 Cy C4 U) L) figM io U) > Cl)CU U, -F 45 CD CD -0C 0 42O o C- = 0 = M M 0 c U) CD cz, LO M cn (D C:5 E :3 (13 >Z, z- -0 --= C17F= 0 co n r fiY f6 G75 CI]0 L) ;; _0 -0 := = := U) �Ei = ff 0 E rt:� - -a ui (D3 C (D -LD CD C:�- 0 CD E U, 0 0 c a) Lo - = 2 2 w cn c E '.

(Requirement ;,,§201.6(c)(2)(ii)) A: See Critical Facilities below. ... . ...... . Critical Facilities FEMA separates critical buildings and facilities into the five categories shown below based on their loss potential. All of the following elements are considered critical facilities: Essential Facilities are essential to the health and welfare of the whole population and are especially important following hazard events. Essential facilities include hospitals and other medical facilities, police and fire stations, emergency operations centers and evacuation shelters, and schools. Transportation Systems include airways — airports, heliports; highways — bridges, tunnels, roadbeds, overpasses, transfer centers-, railways — trackage, tunnels, bridges, rail yards, depots; and waterways — canals, locks, seaports, ferries, harbors, dryclocks, piers. Lifeline Utility Systems such as potable water, wastewater, oil, natural gas, electric power and communication systems. High Potential Loss Facilities are facilities that would have a high loss associated with them, such as nuclear power plants, dams, and military installations. Hazardous Material Facilities include facilities housing industrial/hazardous materials, such as corrosives, explosives, flammable materials, radioactive materials, and toxins. Table: Impacts to Critical Facilities illustrates the hazards with potential to impact critical facilities owned by or providing services to the City of Rosemead.

This level of analysis involves using mathematical models. The two measurable components of risk analysis are magnitude of the harm that may result and the likelihood of the harm occurring. Describing vulnerability in terms of dollar losses provides the community and the state with a common framework in which to measure the effects of hazards on assets. For each hazard where data was available, quantitative estimates for potential losses have been included in the hazard assessment. Data was not available to make vulnerability determinations in terms of dollar losses for all of the identified hazards. The Mitigation Actions Matrix includes an action item to conduct such an assessment in the future. r(n 5) Assessing Vulnerabifilylh?al' ing Development T Inds YZ This step provides a general description of City facilities and contents in relation to the identified hazards so that mitigation options can be considered in land use planning and future land use decisions. This Mitigation Plan provides comprehensive description of the character of the City of Rosemead in the Community Profile Section. This description includes the geography and environment, population and demographics, land use and development, housing and community development, employment and industry, and transportation and commuting patterns. Analyzing these components of the City of Rosemead can help in identifying, potential problem areas and can serve as a guide for incorporating the goals and ideas contained in this mitigation plan into other community development plans. Hazard assessments are subject to the availability of hazard -specific data. Gathering data for a hazard assessment requires a commitment of resources on the part of participating organizations and agencies. Each hazard -specific section of the plan includes a section on hazard identification using data and information from City, County, state, or federal sources. Regardless of the data available for hazard assessments, there are numerous strategies the City can take to reduce risk. These strategies are described in the action items detailed in the Mitigation Actions Matrix in the Mitigation Strategies Section. Mitigation strategies can further reduce disruption to critical services, reduce the risk to human life, and alleviate damage to personal and public property and infrastructure. Land and Development The City of Rosemead General Plan provides the framework for the growth and development of the City. This Plan is one of the City's most important tools in addressing environmental challenges including transportation and air quality; growth management; conservation of natural resources; clean water and open spaces. According to the City's General Plan (2010), the City is designated into five major land use categories: (1) residential, (2) commercial, (3) office/light industrial, (4) mixed-use, and (5) public facilities. Many residential neighborhoods in Rosemead are fully developed and not expected to experience any significant new development or "recycling" (e.g. where an existing structure is removed and a new structure is built in its place).

(Requirement §201.6(c)(2)(i)) A: See Previous Occurrences of Earthqualces in the City of Rosemead below. The following earthquake events significantly impacted the region surrounding the City of Rosemead. In October 1987, the moderate, magnitude 5.9 Whittier Narrows Earthquake, struck the Southern Gabriel Valley with an estimated epicenter in the City of Rosemead. According to Caltech, the earthquake occurred on a previously unknown, concealed thrust fault. It resulted in eight fatalities and $358 million in property damage. Severe damage was confined mainly to communities near the epicenter. ............ Residences that sustained damage usually were . . . . . . . . . . . . 1.1,1111-11111'', constructed of masonry, were not fully anchored to foundations, or were houses built over garages with large door openings. Many chimneys collapsed and in some cases, fell through roofs. Wood frame residences sustained relatively little damage. Since the writing of the 2012 Mitigation Plan, there have been no significant earthquake events in the City of Rosemead. Previous Occurrences of Earthquakes On Los, Angeles County Southern California has a history of powerful and relatively frequent earthquakes, dating back to the powerful magnitude 8.0+ 1857 San Andreas Earthquake which did substantial damage to the relatively few buildings that existed at the time. Paleoseismological research, indicates that large magnitude (M8.0+) earthquakes occur on the San Andreas Fault at intervals between 45 and 332 years with an average interval of 140 years. Other lesser faults have also caused very damaging earthquakes since 1857. Notable earthquakes include the 1933 Long Beach Earthquake, the 1971 San Fernando Earthquake, the 1987 Whittier Earthquake and the 1994 Northridge Earthquake. Scientists have stated that such devastating shaking should be considered the norm near any large thrust earthquake. Recent reports from scientists of the U.S. Geological Survey and the Southern California Earthquake Center say that the Los Angeles Area could expect one earthquake every year of magnitude 5.0 or more for the foreseeable future. a 'ZFFFWo11MMM, MURT71ME Earlhquake I iazards SAM IL,&A I ELEMENT B: HAZARD IDENTIFICATION AND RISK ASSESSMENT I Bla. ,�Q: Does the plan include a general description of alll natural hazards that can affect each jurisdiction?

Is there a description of each identified hazard's overall vulnerability (structures, systems, , populations, or other community assets defined by the community that are identified as being 00 susceptible -to damage and loss from hazard events) for each jurisdiction? (Requirement J§201.6(c)(2)(ii)) A. See Local Conditions below. Local Conditions According to the City of Rosemead General Plan (2010), the City lies within a metropolitan area that has historically been seismically active. Faults are prevalent throughout California and are commonly classified as, either "active" or "potentially active." An active fault is a break that has moved in recent geologic time (the last 11,000 years) and that is likely to move within the next approximately 100 years. Active faults are the primary focus of concern in attempting to prevent earthquake hazards. A potentially active fault is one that has shifted but not in the recent geologic period (or, between 11,000 and 3,000,000 years ago) and is therefore considered dormant or unlikely to move in the future. Several active faults have been identified within close proximity or within the City boundaries which, most importantly, indicates that the community falls under the State Earthquake Fault Zoning Act and the State Hazards Mapping Act. These Acts require that local governments, in the general plan update process, adopt policies and criteria to ensure the structural adequacy of buildings erected across active faults for human occupancy. In some cases, the development of structures must be prohibited. Earthquakes that could affect the City would most likely originate from the San Andreas (M8.0), Sierra Madre (M7.2), or Puente Hills (M7.1) Faults. These faults are close enough in proximity or expected to generate strong enough shaking that could significantly affect the City. Additional faults located within 25 miles of Rosemead include the Whittier (M6.8), Upper Elysian Park (M6.4), Raymond (M6.5), Verclugo (M 6.9), San Jose (M6.4), Hollywood (M6.4), and Clamshell-Sawpit (M6.5) faults. The only known active fault at the surface within the City is the Alhambra Wash fault (zoned as an Alquist-Priolo Earthquake Fault Zone ® APEFZ) as shown on Map: Alquist-Priolo Earthquake Fault Zone. This designation implies the fault is well known, its location is well defined, and potential surface rupture exists. San Andreas Fault Zone The, San Andreas Fault Zone is located approximately 28 miles northeast of the City of Rosemead. This fault zone extends from the Gulf of California northward to the Cape Mendocino area where it continues northward along the ocean floor. The total length of the San Andreas Fault Zone is approximately 750 miles. The activity of the fault has been recorded during historic events, including the 1906 (M8.0) event in San Francisco and the 1857 (M7.9) event between Cholame ii Hazard Mitigation Plan 12018 Earthquake Hazards am and San Bernardino, where at least 250 miles of surface rupture occurred. These seismic events are among the most significant earthquakes in California history. Geologic evidence suggests that the San Andreas Fault has a 50 percent chance of producing a magnitude 7.5 to 8.5 quake (comparable to the great San Francisco earthquake of 1906) within the next 30 years. Sierra Madre Fault Zone The Sierra Madre Fault Zone is located approximately 7 miles north of the City of Rosemead. This fault zone is a series of moderate angle, north -dipping, reverse faults (thrust faults). Movement along these frontal faults has resulted in the uplift of the San Gabriel Mountains. According to the Southern California Earthquake Data Center, rupture on the Sierra Madre fault zone (theoretically) could be limited to one segment at a time, it has recently been suggested that a large event on the San Andreas fault to the north (like that of 1857) could cause simultaneous rupture on reverse faults south of the San Gabriel Mountains — the Sierra Madre fault zone being a prime example of such. Whether this could rupture multiple Sierra Madre fault zone segments simultaneously is unknown. Seismic activity on the Sierra Madre Fault is expected to have a maximum magnitude of 7.2. Puente Hifls Faul't The Puente Hills fault is located approximately 8 miles south of the City. According to USES, the Puente Hills Fault was most recently responsible for the M5.1 La Habra earthquake on March 28, 2014 which caused an estimated $2.6 million in damage. The USGS estimates that a future, larger M7.5 earthquake along the Puente Hills fault could kill 3,000 to 18,000 people and cause up to $250 billion in damage. In contrast, a larger M8.0 quake along the San: Andreas would cause an estimated 1,800 deaths. Alhafnbrci Wash Fault The Alhambra Wash fault is a short northwest -southeast -trending fault in the southern part of the San Gabriel Valley. The fault is approximately 1.5 miles long and extends from 1-60 on the southeast to San Gabriel Boulevard on the northwest. The potential for surface displacement on the Alhambra Wash fault is poorly known, and must be based on empirical fault length/earthquake magnitude relationships. According to these empirical relationships, the maximum magnitude of an event on the Alhambra Wash fault could be about 6.25.

(Requirement §201.6(c)(2)(ii)) A: See Impact of Earthquakes in the City of Rosemead below. Pimpact of Earthquakes In the City of Rosemead Based on the risk assessment, it is evident that earthquakes will continue to have potentially devastating economic impacts to certain areas of the City. Impacts that are not quantified, but can be anticipated in future events, include: V Injury and loss of life; ,/ Commercial and residential structural damage; v' Disruption of and damage to public infrastructure; V Secondary health hazards e.g. mold and mildew; ✓ Damage to roads/bridges resulting in loss of mobility; ✓ Significant economic impact (jobs, sales, tax revenue) upon the community; V Negative impact on commercial and residential property values; and v/ Significant disruption to students and teachers as temporary facilities and relocations would likely be needed. Eard'iquake-Induced I andslidos Earthquake -induced landslides are secondary earthquake hazards that occur from ground shaking. They can destroy the roads, buildings, utilities, and other critical facilities necessary to respond and recover from an earthquake. Many communities in Southern California have a high likelihood of encountering such risks, especially in areas with steep slopes. Seismically induced landslides have the potential to occur in a limited area in the south of Rosemead, but proper geotechnical investigation and mitigation will minimize these secondary seismic hazards. Liquefaction Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other events. Liquefaction occurs in saturated soils, which are soils in which the space between individual soil particles is completely filled with water. This water exerts a pressure on the soil particles that influences how tightly the particles themselves are pressed together. Prior to an earthquake, the water pressure is relatively low. However, earthquake shaking can cause the water pressure to increase to the point where the soil particles can readily move with respect to each other. Because liquefaction only occurs in saturated soil, its effects are most commonly observed in low lying areas. Typically, liquefaction is associated with shallow groundwater, which is less than 50 feet beneath the earth's surface. According to the City of Rosemead's General Plan (2010), liquefaction presents the most prominent secondary earthquake ground failure issue in the City. Liquefaction -related lateral spreads can occur adjacent to stream channel's and deep washes that provide a free face toward which the liquefied mass of soil fails. Lateral spreads can cause extensive damage to pipelines, utilities, bridges, roads and other structures.

L3luilding Inventory HAZUS estimates approximately 93% of the building stock within the City of Rosemead is residential housing consisting of wood frame construction. Critical Facifity Inventory HAZUS breaks critical facilities into two (2) groups: essential facilities and high potential loss facilities (HPL). Essential facilities include hospitals, medical clinics, schools, fire stations, police stations and emergency operations facilities.

These times represent the periods of the day that different sectors of the community are at their peak occupancy loads. The 2:00 AM estimate considers that the residential occupancy load is maximum, the 2:00 PM estimate considers that the educational, commercial and industrial sector loads are maximum and 5:00 PM represents peak commute time. Building -Related Losses Building losses are broken into two categories: direct building losses and business interruption losses. The direct building losses are the estimated costs to repair or replace the damage caused to the building and its contents. The business interruption losses are the losses associated with inability to operate a business because of the damage sustained during the earthquake. Business interruption losses also include the temporary living expenses for those people displaced from their homes because of the earthquake.

Buildings that collapse can trap and bury people. Lives are at risk, and the cost to clean up the damages is great. In most California communities, including the City of Rosemead, many buildings were built before 1993 when building codes were not as strict. In addition, retrofitting is not required except under certain conditions and can be expensive. Therefore, the number of buildings at risk remains high. The California Seismic Safety Commission makes annual reports on the progress of the retrofitting of unreinforced masonry buildings. According to the City of Rosemead General Plan (2010), the City of Rosemead had seven unreinforced masonry structures however five have been strengthened and two were demolished. Implementation of earthquake mitigation policy most often takes place at the local government level. The City of Rosemead Building and Safety Unit enforces building codes pertaining to earthquake hazards. Additionally, the City has implemented basic building requirements that are above and beyond what the State demands for hazard mitigation. Newly constructed buildings in Rosemead that are built in an area subject to Earthquake -induced landslide or liquefaction are typically built with extra foundation support. Such support is found in the post -tension reinforced concrete foundation; this same technique is used by coastal cities to prevent home destruction during cases of liquefaction. Generally, these codes seek to discourage development in areas that could be prone to flooding, landslide, wildfire and/or seismic hazards; and where development is permitted, that the applicable construction standards are met. Developers in hazard -prone areas may be required to retain a qualified professional engineer to evaluate level of risk on the site and recommend appropriate mitigation measures.

Q� Does the plan include information on previous occurrences of hazard events for each jurisdiction? (Requirement §201.6(c)(2)(i)) JA: See Previous Occurrences of Flood in the City of Rosemead below.... PIrevious Occurrences of Flooding in the City of Rosemead Flooding has not been a serious hazard to Rosemead in several decades, and the risk of serious flooding in, the City is considered minimal. Rosemead does not lie within a 100- or 500- year floodplain, as delineated by the Federal Emergency Management Agency (FEMA). However, the potential for a localized flood event still exists within Rosemead, and it is an important hazard to be addressed in the City's Hazard Mitigation Plan. Since the writing of the 2012 Mitigation Plan, heavy rains in January and February of 2017 resulted in flooding to several streets and underpasses in the City of Rosemead. Revious Occurrences of Floodingin Los Angeles County Los Angeles County records reveal since 1861, the Los Angeles River has flooded 30 times, on average once every 6.1 years. But averages are deceiving, for the Los Angeles basin goes through periods of drought and then periods of above average rainfall. Between 1889 and 1891 the river flooded every year, from 1941 to 1945, the river flooded 5 times. Conversely, from 1896 to 1914, and again from 1944 to 1969, a period of 25 years, the river did not have serious floods. Average annual precipitation in Los Angeles County ranges from 13 inches on the coast to approximately 40 inches on the highest point of the Peninsular Mountain Range that transects the County. Several factors determine the severity of floods, including rainfall intensity and duration. A large amount of rainfall over a short time span can result in flash flood conditions. A sudden thunderstorm or heavy rain, dam failure, or sudden spills can cause flash flooding. The National Weather Service's definition of a flash flood is a flood occurring in a watershed where the time of travel of the peak of flow from one end of the watershed to the other is less than six hours. The towering mountains that give the Los Angeles region its spectacular views also wring a great deal of rain out of the storm clouds that pass through. Because the mountains are so steep, the rainwater moves rapidly down the slopes and across the coastal plains on its way to the ocean. Naturally, this rainfall moves rapidly downstream, often with severe consequences for anything in its path. In extreme cases, flood -generated debris flows will roar down a canyon at speeds near 40 miles per hour with a wall of mud, debris and water, tens of feet high. Flooding occurs when climate, geology, and hydrology combine to create conditions where water flows outside of its usual course. lu_�01=39MLIUL.

(Requirement §201.6(c)(2)(ii)) �A- See Local Conditions below. Local Conditions According to the City of Rosemead's General Plan (2010), Rosemead does not have any natural floodplain areas, although it is bordered by the Rio Hondo flood control channel on its eastern and southeastern boundaries. According to FEIVIA, the City of Rosemead is designated a No Special Flood Hazard Area (NSFHA). A Non -Special Flood Hazard Area (NSFHA) is an area that is in a moderate- to low- risk flood zone (Zones B, C, X Pre- and Post-F'IRM). According to Map: Flood Insurance Rate Map, the built areas of the City are in "Flood Zone X" and "Flood Zone V. Zone X is defined as the area outside the 500 -year flood and protected by levee from 100 -year flood. Zone D is defined as areas in which flood hazards are undetermined (no analysis of flood hazards has been conducted), but possible. An NSFHA is not in any immediate danger from flooding caused by overflowing rivers or hard rains. However, it's important to note that structures within a NSFHA are still at risk. In fact, over 20 -percent of all flood insurance claims come from areas outside of mapped high-risk flood zones. Any low-lying urban area is prone to flooding. With Rosemead's geographic location approximately seven to eight from the foot of the San Gabriel mountains, there is a remote possibility of flooding. Flooding in urban areas is likely when water generated by runoff exceeds the storm -drain system's capacity to remove it. National Flood Insurance Program The City participates in the National Flood Insurance Program (NFIP). Created by Congress in 1968, the NFIP makes flood insurance available in communities that enact minimum floodplain management rules consistent with the Code of Federal Regulations §60.3.

Since the writing of the 2012 Mitigation Plan, there have been no dam failure incidents that have impacted the City of Rosemead. PreVious Occurrences of Dain Faflure W Los Angeles County There are a total of 103 dams in Los Angeles County, owned by 23 agencies or organizations, ranging from the Federal government to Home Owner Associations. These dams hold billions of gallons of water in reservoirs. Releases of water from the major reservoirs are designed to protect Southern California from flood waters and to store domestic water. Seismic activity can compromise the dam structures, and the resultant flooding could cause catastrophic flooding. Following the 1971 Sylmar earthquake the Lower Van Norman Dam showed signs of structural compromise, and tens of thousands of persons had to be evacuated until the dam could be drained. The dam has never been refilled. Q&A I ELEMENT B: HAZARD IDENTIFICATION AND RISK ASSESSMENT I Bla.

Because dam failure has severe consequences, FEMA requires that all dam owners develop Emergency Action Plans (EAP) for warning, evacuation, and post -flood actions. Although there may be coordination with county officials in the development of the EAP, the responsibility for developing potential flood inundation maps and facilitation of emergency response is the responsibility of the dam owner. a I'MMMINUITUMUF Mllvlllfl� Dain F-ailure Hazards SIAM 'TableDarns Near, City of Roseinead Garvey Reservoir I Metropolitan Water District I Water Supply Storage Santa Fe Dam Santa Fe Dam and Reservoir is a flood control project in the Los Angeles County Drainage Area (LACDA) flood control system. The dam's embankment is a horseshoe -shaped, curved gravity structure, located on the San Gabriel River, south of Azusa. The project was completed in January 1949. The primary purpose of the dam is to provide flood risk management to the communities along the San Gabriel River downstream of the basin. A total of 2,554 acres was acquired in fee for construction, operation, and maintenance of the Dam. The Corps reserves 1,272 acres exclusively for Dam operations. The remaining 1,282 acres are available for compatible purposes with a p,reference towards recreational purposes. The Corps granted a lease of approximately 836 acres in the Reservoir for recreation purposes to the County of Los Angeles. Whittier Narrows Dam According to the U.S. Army Corps of Engineers, Whittier Narrows Dam is a flood risk management and water conservation project constructed in 1957 and operated by the U.S. Army Corps of Engineers, Los Angeles District. The project is located, as its name implies, at the "Whittier Narrows," a natural gap in the hills that form the southern boundary of the San Gabriel Valley. The Rio Hondo and the San Gabriel rivers flow through this gap and are impounded by the reservoir. Whittier Narrows Dam, a typically dry flood risk management structure located 11 miles east of downtown Los Angeles, has been reclassified from Dam Safety Action Classification (DSAC) 2 to DSAC 1. The DSAC 1 rating indicates that the U.S. Army Corps of Engineers considers the incremental risk — the combination of life or economic consequences with the likelihood of failure — to be very high. The reclassification as DSAC 1 identifies the dam as one of the highest priority dam safety projects in the Corps' portfolio of dams.

The Los Angeles District is currently working with a nationwide team of experts to develop a plan to reduce the risk associated with the spillway. The Corps anticipates that some of the potential solutions will be in operation prior to the 2016-2017 winter rains; other measures will likely be installed before the end of 2017. Gamey Reservoir Garvey Reservoir, owned by the Metropolitan Water District of Southern California (MWD), stores municipal water supplies for MWD customers.

(Requirement §201.6(c)(2)(i)) �A: See Previous Occurrences of Drought in the City of Rosemead below. Previo�City of Rosemead Fortunately, there is no history of severe drought (e.g, restaurants with restricted hours, emergency water distribution to residents, etc.) within the City of Rosemead. However, the City is designated on the U.S. Drought Monitor as having experienced "exceptional drought". This designation comes from a combination of a significant decrease in rain combined with water supply restrictions resulting from the state-wide California drought. These conditions were increasingly evident from 2012 to early in 2017. Since the writing of the 2012 Mitigation Plan, there have been no significant damages to the City from a drought. Previous Occurrences of Drought W Los Angeles County The region's Mediterranean climate makes it especially susceptible to variations in rainfall. Though the potential risk to the City of Rosemead is in, no way unique, severe water shortages could have a bearing on the economic well-being of the community. Comparison of climate (rainfall) records from Los Angeles with water well records beginning in 1930 from the San Gabriel Valley indicates the existence of wet and dry cycles on a 10 -year scale as well as for much longer periods. The climate record for the Los Angeles region beginning in 1890 suggests drying conditions over the last century. With respect to the present day, climate data also suggests that the last significant wet period was the 1940s. Well level data and other sources seem to indicate the historic high groundwater levels (reflecting recharge from rainfall) occurred in the same decade. Since that time, rainfall (and groundwater level trends) appears to be in decline. This slight declining trend, however, is not believed to be significant. Climatologists compiled rainfall data from 96 stations in the State that spanned a 100 -year period between 1890 and 1990. An interesting note is that during the first 50 years of the reporting period, there was only one year (11890) that had more than 35 inches of rainfall, whereas the second 50 -year period recording of 5 -year intervals (1941, 1958, 1978, 1982, and 1983) that exceeded 35 inches of rainfall in a single year. The year of maximum rainfall was 1890 when the average annual rainfall was 43.11 inches. The second wettest year on record occurred in 1983 when the State's average was 42.75 inches. The driest year of the 100 -year reported in the study was 1924 when the State's average rainfall was only 10.50 inches. The region with the most stations reporting the driest year in 1924 was the San Francisco Bay area. The second driest year was 1977 when the average was 11.57 inches. The most recent major drought (1987 to 1990) occurred at the end of a sequence of very wet years (1978 to 1983). The debate continues whether "global warming" is occurring, and the degree to which global climate change will have an effect on local micro -climates. The semi -arid southwest is particularly susceptible to variations in rainfall. A study that documented annual precipitation for California since 1600 from reconstructed tree ring data indicates that there was a prolonged dry spell from about 1755 to 1820 in California. Fluctuations in precipitation could contribute indirectly to a number of hazards including wildfire and the availability of water supplies. Hazard Mitigation Plan 12018 Otought Hazards Imm Ax4h R6)s vrr jQ: Does the plan include a general description of all natural hazards that can affect each juriscliction? (Requirement §201.6(c)(2)(i)) O'A: See Local Conditions below. Is there a description of each identified hazard's overall vulnerability (structures, systems, populations, or other community assets defined by the community that are identified as being so susceptible to damage and loss from hazard events) for each jurisdiction? (Requirement §201.6(c)(2)(ii)) A: See Local Conditions below. Local Conditions According to the City of Rosemead General Plan, water resources are limited to the groundwater basins that provide a local source of water to the City and the surrounding region. Rosemead is located above the San Gabriel Basin, a groundwater basin drained by the San Gabriel River and the Rio Hondo. The groundwater basin is bounded by the San Gabriel Mountains to the north, San Jose Hills to the east, Puente Hills to the south, and Raymond Fault to the west. Local groundwater accounts for a major portion of the area's water supply. Three of the groundwater purveyors in the City are the Upper San Gabriel Valley Municipal Water District, the South San Gabriel System (serves half of Rosemead), and the California Water Service Company. A significant drought has hit the state of California since 2012. The drought has depleted reservoir levels all across the state. In January of 2014, Governor Brown declared a state of emergency and directed state officials to take all necessary actions to prepare for water shortages. As the drought prolonged into 2015, to help cope with the drought, Governor Brown gave an executive order in April 2015 which mandated a statewide 25 percent reduction in water use. In January of 2016, the DWR and the U.S. Bureau of Reclamation have finalized the 2016 Drought Contingency Plan that outlines State Water Project and Central Valley Project operations for February 2016 to November 2016.1The plan was developed in coordination with staff from State and federal agencies. Although the drought has more significantly impacted surfaces waters and other agencies that use water for agriculture, the City of Rosemead is still affected by the drought, primarily due to reduced reliability of imported water. In 2015, the City Council passed a Water Conservation Ordinance identifying 3 phases of conservation depending on severity of conditions as per the determination of the State Water Resources Control Board. An additional concern relating to water resources is the existence of pollution in the groundwater. The General Plan notes that due to past San Gabriel Valley industrial practices, the basin has been contaminated with a variety of pollutants ranging from pesticides to industrial chemicals and solvents. According to the Environmental Protection Agency (EPA), over 30 square miles of San Gabriel Valley groundwater may be contaminated. The contaminated sites underlie Rosemead and other San Gabriel Valley communities. Although the federal government is responsible for cleanup of the area and initiated a comprehensive remediation program in 1994, Rosemead is committed to reducing the further contamination of underground water. The City a Hazard Mitigation Plan 12018 Drought Hazards 5ME KO.S & 4EAA D participates in Los Angeles County's NPDES program to reduce the amount of water polluted by pesticides, engine oil, and household chemicals that run into the storm drain system and pollute groundwater. As part of this effort, the City must comply with the County's Stormwater Quality Management Program and implement Best Management Practices (BMPs) in several areas including public outreach, planning and construction, public agency activities, business inspections, and illicit connection and flow. A &A I ELEMENT B: HAZARD IDENTIFICATION AND RISK ASSESSMENT I 133a, Q: Is there a description of each hazard's impacts on each jurisdiction (what happens to structures, infrastructure, people, environment, etc.)? (Requirement §201.6(c)(2)(ii)) A: See Impact of Drought in the City of ??? below. Impacts of Drought"On the City of Rosemead Based on the risk assessment, it is evident that drought events continue to have the potential to yield devastating economic impacts to the City. Impacts that are not quantified, but can be anticipated in future events, include: • Injury and loss of life • Disruption of and damage to public infrastructure • Significant economic impact (jobs, sales, tax revenue) upon the community • Negative impact on commercial and residential property values ,/ Uncontrolled fires and associated injuries and damage a Hazard Mitigation Plan 12018 Drooght Jr-lazards 9RE OVOPAGW of mit1gation Strategy As the cost of damage from natural disasters continues to increase nationwide, the City of Rosemead recognizes the importance of identifying effective ways to reduce vulnerability to disasters. Mitigation Plans assist communities in reducing risk from natural hazards by identifying resources, information and strategies for risk reduction, while helping to guide and coordinate mitigation activities throughout the City. The plan provides a set of action items to reduce risk from natural hazards through education and outreach programs, and to foster the development of partnerships. Further, the plan provides for the implementation of preventative activities, including programs that restrict and control development in areas subject to damage from natural hazards. The resources and information within the Mitigation Plan: 1. Establish a basis for coordination and collaboration among agencies and the public in the City of Rosemead; 2. Identify and prioritize future mitigation projects; and 3. Assist in meeting the requirements of federal assistance programs The Mitigation Plan is integrated with other City plans including the City of Rosemead Emergency Operations Plan, General Plan as well as department -specific standard operating procedures. Mitigation Measure Categories Following is FEMA's list of mitigation categories. The activities identified by the Planning Team are consistent with the six broad categories of mitigation actions outlined in FEMA publication 386-3 Developing the Mitigation Plan; Identifying Mitigation Actions and Implementing Strategies. • Prevention. Government administrative or regulatory actions or processes that influence the way land and buildings are developed and built. These actions also include public activities to reduce hazard losses. Examples include planning and zoning, building codes, capital improvement programs, open space preservation, and storm water management regulations. • Property Protection: Actions that involve modification of existing buildings or structures to protect them from a hazard, or removal from the hazard area. Examples include acquisition, elevation, relocation, structural retrofits, storm shutters, and shatter -resistant glass. ✓ Public Education and Awareness: Actions to inform and educate citizens, property owners, and elected officials about hazards and potential ways to mitigate them. Such actions include outreach projects, real estate disclosure, hazard information centers, and school-age and adult education programs. V Natural Resource Protection: Actions that, in addition to minimizing hazard losses preserve or restore the functions of natural systems. Examples include sediment and Hazard Mitigation Plan 12018 h4itigafion shategies INM erosion control, stream corridor restoration, watershed management, forest and vegetation management, and wetland restoration and preservation. Emergency Services: Actions that protect people and property during and immediately following a disaster or hazard event. Services include warning systems, emergency response services, and protection of critical facilities. ✓ Structural Projects: Actions that involve the construction of structures to reduce the impact of a hazard. Such structures include dams, levees, floodwalls, retaining walls, and safe rooms. Q&A I ELEMENT C. MITIGATION STRATEGY I C3 Q: Does the Plan include goals to reduce/avoid long-term vulnerabilities to the identified i hazards? (Requirement §201.6(c)(3)(i)) A: See Goals below. Goals In the 2012 HMP, the Planning Team identified the overall goal of avoiding or reducing long-term vulnerabilities to hazards. The Team agreed to maintain the overall ------ - --- ... . .......... --------- goal as well as the five mitigation goals identified below. FEMA defines Goals as The goals are based on the risk assessment and Planning Team input, and represents a long-term vision for hazard reduction or enhanced mitigation capabilities. They are compatible with community needs and goals expressed in other planning documents prepared by the City. Each goal is supported by mitigation action items. The Planning Team developed these action items through its knowledge of the local area, risk assessment, review of past efforts, identification of mitigation activities, and qualitative analysis. The five mitigation goals and descriptions are listed below. Protect Life, ar'0 Property Implement activities that assist in protecting lives by making homes, businesses, infrastructure, critical facilities, and other property more resistant to losses from natural, human -caused, and technological hazards. general guidelines that explain what you want to achieve., They are usually broad policy -type statements, long-term, and represent global visions. FEMA defines Mitigation Activities as specific actions that help you achieve your goals and objectives, Improve hazard assessment information to make recommendations for avoiding new development in high hazard areas and encouraging preventative measures for existing development in areas vulnerable to natural, human -caused, and technological hazards. a Hazard Mitigation Plan 1 2018 Mitigation Strategies E'nhance Public Awareness Develop and implement education and outreach programs to increase public awareness of the risks associated with natural, human -caused, and technological hazards. Provide information on tools; partnership opportunities, and funding resources to assist in implementing mitigation activities. Presei ve Natutal Systeuis Support management and land use planning practices with hazard mitigation to protect life. Preserve, rehabilitate, and enhance natural systems to serve hazard mitigation functions. Encourage Paitnierships and Itriplee eritation Strengthen communication and coordinate participation with public agencies, citizens, non-profit organizations, business, and industry to support implementation. Encourage leadership within the City and public organizations to prioritize and implement local and regional hazard mitigation activities. Strengthen EmergencY Senlices Establish policy to ensure mitigation projects for critical facilities, services, and infrastructure. Strengthen emergency operations by increasing collaboration and coordination among public agencies, non-profit organizations, business, and industry. Coordinate and integrate hazard mitigation activities where appropriate, with emergency operations plans and procedures. The Planning Team also developed hazard -specific mitigation goals, which appear in the Mitigation Strategies Section. How are the Mitigation Action Items Owganlzed? The action items are a listing of activities in which City agencies and citizens can be engaged to reduce risk. Each action item includes an estimate of the timeline for implementation. The action items are organized within the following Mitigation Actions Matrix, which lists all of the multi -hazard (actions that reduce risks for more than one specific hazard) and hazard -specific action items included in the mitigation plan. Data collection and research and the public participation process resulted in the development of these action items. The Matrix includes the following information for each action item: Funding Source The action items can be funded through a variety of sources, possibly including. operating budget/general fund, development fees, Community Development Block Grant (CNBC), Hazard Mitigation Grant Program (HMGP), other Grants, private funding, Capital Improvement Plan, and other funding opportunities. Mitigation stra'tegies IMN Coordinatirig Organization The Mitigation Actions Matrix assigns primary responsibility for each of the action items. The hierarchies of the assignments vary — some are positions, others departments, and other committees. The primary responsibility for implementing the action items falls to the entity shown as the "Coordinating Organization". The coordinating organization is the agency with regulatory responsibility to address hazards, or that is willing and able to organize resources, find appropriate funding, or oversee activity implementation, monitoring, and evaluation. Coordinating organizations may include local, County, or regional agencies that are capable of or responsible for implementing activities and programs. Plan Goals Addressed The plan goals addressed by each action item are included as a way to monitor and evaluate how well the mitigation plan is achieving its goals once implementation begins. The plan goals are organized into the following five areas: ✓ Protect Life and Property ✓ Enhance Public Awareness ✓' Preserve Natural Systems ✓ Encourage Partnerships and Implementation ✓ Strengthen Emergency Services Pk,inning Mechanisin it's important that each action item be implemented. Perhaps the best way to ensure implementation is through integration with one or many of the City's existing "planning mechanisms" including the General Plan, Capital Improvement Program, General Fund and Grants. Opportunities for integration will be simple and easy in cases where the action item is already compatible with the content of the planning mechanism. As an example, if the action item calls for the creation of a floodplain ordinance and the same action is already identified in the General Plan's policies, then the General Plan will assist in implementation. On the contrary, if preparation of a floodplain ordinance is not already included in the General Plan policies then, the item will need to be added during the next update to the General Plan. The General Plan was last updated in 2010 and was used as a resource throughout the Mitigation Plan. The next General Plan update will likely not take place for another 20 years. The Capital Improvement Program, depending on the budgetary environment, is updated every 5 years. The CIP includes infrastructure projects built and owned by the City. As such, the CIP is an excellent medium for funding and implementing action items from the Mitigation Plan. The Mitigation Actions Matrix Includes several items from the existing CIP. The authors of the CIP served on the Planning Team and are already looking to funding addition Mitigation Plan action items in future CIPS. The General Fund is the budget document that guides all of the City's expenditures and is updated on an annual basis. Although primarily a funding mechanism, it also includes descriptions and details associated with tasks and projects. a Hazard Mitigation Plan 12018 Uifryation Sirategies sum M Grants come from a wide variety of sources — some annually and other triggered by events like disasters. Whatever the source, the Town uses the General Fund to identify successful grants as funding sources. Bijildit'ig and Infaistructure, This addresses the issue of whether or not a particular action item results in the reduction of the effects of hazards on new and existing buildings and infrastructure. Corriments The purpose of the "Comments" is to capture the notes and status of the various action items. Since Planning Team members frequently change between plan updates and annual reviews, the Comments provide a sort of history to help in tracking the progress and status of each action. Comments are expressed in terms of Completed, Revised, Deleted, New, Deferred', and Notes. ��- �Urmt�= Allili�gafioo Strategies 9NM Q&A I ELEMENT C. MITIGATION STRATEGY I CSa. Q: Does the plan explain how the mitigation actions and projects will be prioritized (including cost benefit review)? (Requirement §201.6(c)(3)(iv)); (Requirement §201.6(c)(3)(iii)) A: See Benefit/Cost Ratings and Priority Rating below. Benefill(Ast Ratings The benefits of proposed projects were weighed against estimated costs as part of the project prioritization process. The benefit/cost analysis was not of the detailed variety required by FEMA for project grant eligibility under the Hazard Mitigation Grant Program (HMGP) and Pre -Disaster Mitigation (PDM) grant program. A less formal approach was used because some projects may not be implemented for up to 10 years, and associated costs and benefits could change dramatically in that time. Therefore, a review of the apparent benefits versus the apparent cost of each project was performed. Parameters were established for assigning subjective ratings (high, medium, and low) to the costs and benefits of these projects. Cost ratings were defined as follows: High: Existing jurisdictional funding will not cover the cost of the action item so other sources of revenue would be required. Medium: The action item could be funded through existing jurisdictional funding but would require budget modifications. Low: The action item could be funded under existing jurisdictional funding. Benefit ratings were defined as follows: a High: The action item: will provide short-term and long-term impacts on the reduction of risk exposure to life and property. MediumThe action item will have long-term impacts on the reduction of risk exposure to life and property. Low: The action item will have only short-term impacts on the reduction of risk exposure to life and property. Hazard Mitigation Plan 12018 MitkIation Strategies sm Priority Rating Going beyond rating "benefit and cost" as used in the 2.012 HMP, the Planning Team adopted the following process for rating the "priority" of each mitigation action item. Designations of "High", "Medium", and "Low" priority have been assigned to each action item using the following criteria: Does the Action: [I solve the problem? L address Vulnerability Assessment? El reduce the exposure or vulnerability to the highest priority hazard? F-1 address multiple hazards? E benefits equal or exceed costs? Ll implement a goal, policy, or project identified in the General Plan or Capital Improvement Plan? Can the Action: Ei be implemented with existing funds? Ll be implemented by existing state or federal grant programs? Li be completed within the 5 -year life cycle of the LHMP? F1 be implemented with currently available technologies? Will the Action: Li be accepted by the community? Li be supported by community leaders? F -I adversely impact segments of the population or neighborhoods? Li require a change in local ordinances or zoning laws? Ll positive or neutral impact on the environment? L comply with all local, state and federal environmental laws and regulations? Is there: E sufficient staffing to undertake the project? L existing authority to undertake the project? As mitigation action items were updated or written, the Planning Team, representatives were provided worksheets for each of their assigned action items. Answers to the criteria above determined the priority according to the following scale. 0 1-6 = Low priority 0 7-12, = Medium priority 0 13-18 = High prio rity Hazard Mitigation Plan 12018 Mitigation Strategies 31M m LM, Q&A I ELEMENT C.

Q: Does the plan identify how, when, and by whom the plan will be monitored (how will implementation be tracked) over time? (Requirement §201.6(c)(4)(i)) A: See Method and Scheduling of Plan Implementation below. IV Method and Scheduling of Plan Implementatioll The Planning Team that was involved in research and writing of the Plan will also be responsible for implementation. The Planning Team will be led by the Planning Team Chair (Mandy Wong - Public Safety Department - Public Safety Supervisor) who will be referred to as the Local Mitigation Officer. Monitoring and Implementing the Plan The City Council will be responsible for adopting the Mitigation Plan. This governing body has the authority to promote sound public policy regarding hazards. Once the plan has been adopted, the Local Mitigation Officer will be responsible for submitting. it to the State Hazard Mitigation Officer at California Office of Emergency Services (Cal OES). Cal OES will then submit the plan to the Federal Emergency Management Agency (FEMA) for review and approval. This review will address the requirements set forth in 44 C.F.R. Section 201.6 (Local Mitigation Plans). Upon acceptance by FEMA, City of Rosemead will gain eligibility for Hazard Mitigation Grant Program funds. Local Mitigation Officer Under the direction of the Local Mitigation Officer, the Planning Team will take responsibility for plan maintenance and implementation, The Local Mitigation Officer will facilitate the Planning Team meetings and will assign tasks such as updating and presenting the Plan to the members of the Planning Team. Plan implementation and evaluation will be a shared responsibility among all of the Planning Team members. The Local Mitigation Officer will coordinate with City leadership to ensure funding and support for 5 -year updates to Plan as required by FEMA. a Hazard Mitigation Plan 12018 Plan Mainteoalr1ce MILM P", G The Planning Team will be responsible for coordinating implementation of plan action items and undertaking the formal review process. The Local Mitigation Officer will be authorized to make changes in assignments to the current Planning Team. The Planning Team will meet no less than quarterly to review the status of the mitigation action items. Meeting dates will be scheduled once the final Planning Team has been established. These meetings will provide an opportunity to discuss the progress of the action items and maintain the partnerships that are essential for the sustainability of the mitigation plan. Q&A ELEMENT C. MITIGATION STRATEGY I Cha. Q: Does the plan identify the local planning mechanisms where hazard mitigation information and/or actions may be incorporated? (Requirement §201.6(c)(4)(ii)) f A: See Implementation through Existing Program below. Implementation through Existing Progratris The City of Rosemead addresses statewide planning goals and legislative requirements through its Generali Plan, its Capital Improvement Plan, and the State's Building and Safety Codes. The Mitigation Plan provides a series of recommendations - many of which are closely related to the goals and objectives of existing planning programs. The City of Rosemead will incorporate hazard information and implement recommended mitigation, action items through existing programs and procedures. The City of Rosemead Community Development Department is responsible for adhering to the State of California's Building and Safety Codes. In addition, the Planning Team will work with other agencies at the state level to review, develop and ensure the adopted Building and Safety Codes are adequate to mitigate or present damage by hazards. This is to ensure that life -safety criteria are met for new construction. Some of the goals and action items in the Mitigation Plan will be achieved through activities recommended in the CIP. Various City departments develop the CIP and review it on an annual basis. Upon annual review of the CIP, the Planning Team will work with the City departments to identify areas that the Mitigation Plan action items are consistent with CIP goals and integrate them where appropriate. Upon FEMA approval, the Planning Team will begin the process of incorporating existing planning mechanisms at the City level. The meetings of the Planning Team will provide an opportunity for Planning Team members to report back on the progress made on the integration of mitigation planning elements into City planning documents and procedures. Upon FEMA approval, the Planning Team will begin the process of incorporating risk information and mitigation action items into existing planning mechanisms including the General Plan, Capital Improvement Program, and other planning mechanisms (see Mitigation Action Matrix for links between individual action items and associated planning mechanism). The meetings of the Planning Team will provide an opportunity for Planning Team members to report back on the progress made on the integration of mitigation planning elements into City planning documents and procedures. a Hazard Mitigation Plan 12018 Plan Maintenance milm Specifically, the Planning Team will utilize the updates of the following documents to implement the Mitigation Plan: • Risk Assessment, Community Profile, Planning Process (stakeholders) — General Plan Land Use Element, City's Emergency Operations Plan • Community Profile — General Plan Housing Element • Risk Assessment, Hazard -Specific Sections, General Hazard Overviews — General Plan Safety Element • Mitigation Actions Matrix — Annual Budget, Capital Improvement Program rg F -V f NOW FA1re1'11T`q1110WA W 141# es Ptu'U1641 111"T'l I&I TIT d 16-4T *1 We 1[11LISd EA _7f_dV,0f_ specifically identified as coming from the 2012 Hazard Mitigation Plan. i-conornic Anal.ylsis of Mitigafion Pro.*ts FEMA's approach to identify the costs and benefits associated with hazard mitigation strategies, measures, or projects fall into two general categories: benefit/cost analysis and cost-effectiveness analysis. Conducting benefit/cost analysis for a mitigation activity can assist communities in determining whether a project is worth undertaking now, in order to avoid disaster -related damages later. Cost-effectiveness analysis evaluates how best to spend a given amount of money to achieve a specific goal. Determining the economic feasibility of mitigating hazards can provide decision - makers with an understanding of the potential benefits and costs of an activity, as well as a basis upon which to compare alternative projects. Given federal funding, the Planning Team will use a FEMA -approved benefit/cost analysis approach to identify and prioritize mitigation action items. For other projects and funding sources, the Planning Team will use other approaches to understand the costs and benefits of each action item and develop a prioritized list. The "benefit", "cost", and overall "priority" of each mitigation action item was included in the Mitigation Actions Matrix located in Part III: Mitigation Strategies. A more technical assessment will be required in the event grant funding is pursued through the Hazard Mitigation Grant Program. FEMA Benefit -Cost Analysis Guidelines are discussed below. FIEWA Be ne fit- Cost Analysis Guidelines The Stafford Act authorizes the President to establish a program to provide technical and financial assistance to state and local governments to assist in the implementation of hazard mitigation measures that are cost effective and designed to substantially reduce injuries, loss of life, hardship, or the risk of future damage and destruction of property. To evaluate proposed hazard mitigation projects prior to funding FEMA requires a Benefit -Cost Analysis (BCA) to validate cost effectiveness. BCA is the method by which the future benefits of a mitigation project are estimated and compared to its cost. The end result is a benefit -cost ratio (BCR), which is derived from: a project's total net benefits divided by its total project cost. The BCR is a numerical expression of the cost effectiveness of a project. A project is considered to be cost effective when the BCR is R! ",'a, Hazard Mitigation Plan 12018 Felin Maintenance Sam 1.0 or greater, indicating the benefits of a prospective hazard mitigation project are sufficient to justify the costs. Although the preparation of a BCA is a technical process, FEMA has developed software, written materials, and training to support the effort and assist with estimating the expected future benefits over the useful life of a retrofit project. It is imperative to conduct a BCA early in the project development process to ensure the likelihood of meeting the cost-effective eligibility requirement in the Stafford Act. The BCA program consists of'guidelines, methodologies and software modules for a range of major natural hazards including: • Flood (Riverine, Coastal Zone A, Coastal Zone V) • Hurricane Wind ✓ Hurricane Safe Room • Damage -Frequency Assessment • Tornado Safe Room • Earthquake V Wildfire The BCA program provides up to date program data, up to date default and standard values, user manuals and training. Overall, the program makes it easier for users and evaluators to conduct and review BCAs and to address multiple buildings and hazards in a single BCA module run. Q&A I ELEMENT A: PLANNING PROCESS I A6a. Q: Does the plan identify how, when, and by whom the plan will be monitored (how will implementation be tracked) over time?

Does the plan identify how, when, and by whom the plan will be updated during the 5 -year cycle? (Requirement §201.6(c)(4)(i)) I A: See Evaluating and Updating the Plan below. Eg and Updating the Plan The Planning Team will be responsible for coordinating implementation of plan by monitoring the progress of the mitigation action items and documenting progress notes for each item. It will be up to the Local Mitigation Officer to hold either a live meeting versus tasking the coordinating agencies with status updates on their own assigned mitigation action items. The monitoring meetings will take place no less than quarterly. These meetings will provide an opportunity to discuss the progress of the action items and maintain the partnerships that are essential for the sustainability of the mitigation plan. See the Quarterly Implementation Report discussed below which will be a valuable too] for the Planning Team to measure the success of the Hazard Mitigation Plan. The focus of the quarterly meetings will be on the progress and changes to the Mitigation Action Items. Hazard Mitigation Plan 12018 Ran Allainteoance Quarterly Implementation Report The Quarterly Implementation Report is the same as the Mitigation Action Matrix but with a column added to the far right to track the quarterly status of each Action Item. Upon approval and adoption of the Plan, the entire Quarterly Implementation Report will be added to the Appendix of the Plan. Following is a view of the Quarterly Implementation Report: An equally part of the monitoring process is the need to maintain a strategic planning process which needs to include funding and organizational support. In that light, at least one year in advance of the FEMA -mandated 5 -year submission of an update, the Local Mitigation Officer will convene the Planning Team to discuss funding and timing of the updater planning process. On the fifth year of the planning cycles, the Planning Team will broaden its scope to include discussions and research on all of the sections within the Plan with particular attention given go goal achievement and public participation. Q&A JELEMENT A: PLANNING PROCESS I A6b- Q: Does the plan identify how, when, and by whom the plan will be evaluated (assessing the effectiveness of the plan at achieving stated purpose and goals) over time? (Requirement §201.6(c)(4)(i)) A: See Evaluation below. At the conclusion of the 4th Quarterly Report meeting each year, the Local Mitigation Officer will lead a discussion with the Planning Team on, the success (or failure) of the Mitigation Plan to meet the Plan Goals. The results of that discussion will be added to the 4th Quarterly Report and inclusion in the 5 -year update to the Plan. Efforts will be made immediately by the Local Mitigation Officer to address any failed Plan Goals. ii Hazard Mitigation Plan 12018 Plan Maiotenance MUM. Fonnal Update Process The Mitigation Plan will be monitored on a quarterly basis to determine the effectiveness of mitigation action items and to reflect changes in land development or programs that may affect mitigation actions or their priorities. The evaluation process includes a firm schedule and timeline, and identifies the agencies and organizations participating in plan evaluation. The Local Mitigation Officer or designee will be responsible for contacting the Planning Team members and organizing the quarterly meeting. Planning Team members will also be responsible for participating in the formal update to the Plan every fifth year of the planning cycle. The Planning Team will review the goals and mitigation action items to determine their relevance to changing situations in the City, as well as changes in State or Federal policy, and to ensure they are addressing current and expected conditions. The Planning Team will also review the Plan's Risk Assessment portion of the Plan to determine if this information should be updated or modified, given any new available data. The coordinating organizations responsible for the various action items will report on the status of their projects, including the success of various implementation processes, difficulties encountered, success of coordination efforts, and which strategies should be revised. Amending will be made to the Mitigation Actions Matrix and other sections in the Plan as deemed necessary by the Planning Team. Q&A I ELEMENT A: PLANNING PROCESS I AS Q� Is there discussion of how the community(ies) will continue public participation in the plan maintenance process? (Requirement §201.6(c)(4)(iii)) A. See Continued Public Involvement below. Continued Public Involvement The City of Rosemead is dedicated to involving the public directly in the continual review and updates to the Mitigation Plan. Copies of the plan will be catalogued and made available at City Hall and at all City operated public libraries. The existence and location of these copies will be publicized in City newsletters and on the City website. This site will also contain an email address and phone number where people can direct their comments and concerns. A public meeting will also be held after each evaluation or when deemed necessary by the Planning Team. The meetings will provide the public a forum in which they can express their concerns, opinions, or ideas about the Plan. The Local Mitigation Officer will be responsible for using City resources to publicize the annual public meetings and maintain public involvement through the public access channel, web page, and newspapers. Hazard Mitigation Plan 12018 Plan Maintenance Elm MR, Earthquake Hazards Measuring and Describing Earthquakes An earthquake is a sudden motion or trembling that is caused by a release of strain accumulated within or along the edge of the Earth's tectonic plates. The effects of an earthquake can be felt far beyond the site of its occurrence. They usually occur without warning and, after just a few seconds, can cause massive damage and extensive casualties. Common effects of earthquakes are ground motion and shaking, surface fault ruptures, and ground failure. Ground motion is the vibration or shaking of the ground during an earthquake. When a fault ruptures, seismic waves radiate, causing the ground to vibrate. The severity of the vibration increases with the amount of energy released and decreases with distance from the causative fault or epicenter. Soft soils can further amplify ground motions. The severity of these effects is dependent on the amount of energy released from the fault or epicenter. One way to express an earthquake's severity is to compare its acceleration to the normal acceleration due to gravity. The acceleration due to gravity is often called "g". A ground motion with, a peak ground acceleration of 1 00%g is very severe. Peak Ground Acceleration (PGA) is a measure of the strength of ground motion. PGA is used to project the risk of damage from future earthquakes by showing When afault ruptures, earthquake ground motions that have a specified probability (10%, 5%, or 2%) of being exceeded in 50 years. These ground motion seismic waves radiate, values are used for reference in construction design for earthquake causing the ground to resistance. The ground motion values can also be used to assess relative hazard between sites, when making economic and safety vibrate. The severity of the decisions. vibration increases with Another tool used to describe earthquake intensity is the Magnitude the amount of energy Scale. The Magnitude Scale is sometimes referred to as the Richter released and decreases Scale. The two are similar but not exactly the same. The Magnitude Scale was devised as a means of rating earthquake strength and is with distance from the an indirect measure of seismic energy released. The Scale is causative fault or logarithmic with each one -point increase corresponding to a 10 -fold increase in the amplitude of the seismic shock waves generated by epicenter. the earthquake. In terms of actual energy released, however, each one -point increase on the Richter scale corresponds to about a 32 - fold increase in energy released. Therefore, a Magnitude 7 (M7) earthquake is 100 times (10 X 10) more powerful than a M5 earthquake and releases 1,024 times (32 X 32) the energy. An earthquake generates different types of seismic shock waves that travel outward from the focus or point of rupture on a fault. Seismic waves that travel through the earth's crust are called body waves and are divided into primary (P) and secondary (S) waves. Because P waves move faster (1.7 times) than S waves, they arrive at the seismograph first. By measuring the time delay between arrival of the P and S waves and knowing the distance to the epicenter, seismologists can compute the magnitude for the earthquake. lm� =1119 MMUo Gemeral Hazard Oveiviews I Eadhquake !..Wards 91" The duration of an earthquake is related to its magnitude but not in a perfectly strict sense. There are two ways to think about the duration of an earthquake. The first is the length of time it takes for the fault to rupture and the second is the length of time shaking is felt at any given point (e.g. when someone says, "I felt it shake for 10 seconds" they are making a statement about the duration of shaking). (Source: www.usgs,gov) The Modified Mercalli Scale (MMI) is another means for rating earthquakes, but one that attempts to quantify intensity of ground shaking. Intensity under this scale is a function of distance from the epicenter (the closer to the epicenter the greater the intensity), ground acceleration, duration of ground shaking, and degree of structural damage. The Modified Mercalli Intensity Scale below rates the level of severity of an earthquake by the amount of damage and perceived shaking. fable: n/iodified i4ercall!

The severity of these hazards depends on several factors, including soil and slope conditions, proximity to the fault, earthquake magnitude, and the type of earthquake. Ground Shaking Ground shaking is the motion felt on the earth's surface caused by seismic waves generated by the earthquake. It is the primary cause of earthquake damage. The strength of ground shaking depends on the magnitude of the earthquake, the type of fault, and d,istance from the epicenter (where the earthquake originates). Buildings on poorly consolidated and thick soils will typically see more damage than buildings on consolidated soils and bedrock. Seismic activity along nearby or more distant fault zones are likely to cause ground shaking within the City limits. Ear,t1Jqijake-1nduc(,:.,d L.aridsfide Potential Generally, these types of failures consist of rock falls, disrupted soil slides, rock slides, soil lateral spreads, soil slumps, soil block slides, and soil avalanches. Areas having the potential for earthquake -induced landslides generally occur in areas of previous landslide movement, or where local topographic, geological, geotechnical, and subsurface water conditions indicate a potential for permanent ground displacements. Liquefaction Liquefaction occurs when ground shaking causes wet granular soils to change from a solid state to a liquid state. This results in the loss of soil strength and the soil's ability to support weight. Buildings and their occupants are at risk when the ground can no longer support these structures. Liquefaction generally occurs during significant earthquake activity, and structures located on soils such as silt or sand may experience significant damage during an earthquake due to the instability of structural foundations and the moving earth. Many communities in Southern California are built on ancient river bottoms and have sandy soil. In some cases, the soil may be subject to liquefaction, depending on the depth of the water table. a Hazard Mitigation Plan ll 2018 General Hazard Overviews I Earthquake [4azatds SHE M Flood Hazards Flood Terminology Floodplain A floodplain is a land area adjacent to a river, stream, lake, estuary, or other water body that is subject to flooding. This area, if left undisturbed, acts to store excess flood water. The floodplain is made up of two sections: the floodway and the flood fringe. I 00 -'Year Flood The 100 -year flooding event is the flood having a one percent chance of being equaled or exceeded in magnitude in any given year. Contrary to popular belief, it is not a flood occurring once every 100 years. The 100 -year floodplain is the area adjoining a river, stream, or watercourse covered by water in the event of a 100 -year flood, Schematic: Floodplain and Floodway shows the relationship of the floodplain and the floodway. Figure: l9oodpWn and floodway (SOUrce: F'EMA IHow-To-Guide Assessh'ug Hazards) The 100 -year flooding event is the flood having a 1% chance of being equaled or exceeded in magnitude in any guven year. The floodway is one of two main sections that make up the floodplain. Floodways are defined for regulatory purposes. Unlike floodplains, floodways do not reflect a recognizable geologic feature. For NFIP purposes, floodways are defined as the channel of a river or stream, and the overbank areas adjacent to the channel. The floodway carries the bulk of the flood water downstream and is usually the area where water velocities and forces are the greatest. NFIP regulations require that the floodway be kept open and free from development or other structures that would obstruct or divert flood flows onto other properties. General Hazard Ovendews G Flood Hazards M Base Rood Elevation (BFE) The term "Base Flood Elevation" refers to the elevation (normally measured in feet above sea level) that the base flood is expected to reach. Base flood elevations can be set at levels other than the 100 -year flood. Some communities use higher frequency flood events as their base flood elevation for certain activities, while using lower frequency events for others. For example, for the purpose of storm water management, a 25 -year flood event might serve as the base flood elevation; while the 500 -year flood event serves as base flood elevation for the tie down of mobile homes. The regulations of the NFIP focus on development in the 100 -year floodplain. Types of Hooding Two types of flooding can affect the City of Rosemead: slow -rise or flash flooding. Slow -rise floods in Rosemead may be preceded by a warning period of hours or days. Evacuation and sandbagging for slow -rise floods have often effectively lessened flood related damage. Conversely, flash floods are most difficult to prepare for, due to extremely limited, if any, advance warning and preparation time. Unlike most of California, the areas of Los Angeles County that are subject to slow -rise flooding are not associated with overflowing rivers, aqueducts, canals or lakes. Slow -rise flooding in Rosemead is usually the result of one or a combination of the following factors: extremely heavy rainfall, saturated soil, area recently burned in wild fires with inadequate new ground cover growth, or heavy rainfall with runoff from melting, mountain snow. L)rban Flooding As land is converted from fields or woodlands to roads and parking lots, it loses its ability to absorb rainfall. Urbanization of a watershed changes the hydrologic systems of the basin. Heavy rainfall collects and flows faster on impervious concrete and asphalt surfaces. The water moves from the clouds, to the ground, and into streams at a much faster rate in urban areas. Adding these elements to the hydrological systems can result in flood waters that rise very rapidly and peak with violent force. The City of Rosemead has a high concentration of impermeable surfaces that either collect water, or concentrate the flow of water in unnatural channels. During periods of urban flooding, streets can become swift moving rivers and basements can fill with water. Storm drains often, back up with vegetative debris causing additional, localized flooding. Drainage systems within the City of Rosemead have been, updated and it is anticipated that they would be fully functional in an emergency. Riverine Flooding Riverine flooding is the overbank flooding of rivers and streams. The natural processes of riverine flooding add sediment and nutrients to fertile floodplain areas. Flooding in large river systems typically results from large-scale weather systems that generate prolonged rainfall over a wide geographic area, causing flooding in hundreds of smaller streams, which then drain into the major rivers. Shallow area flooding is a special type of riverine flooding. FEMA defines shallow flood hazards as areas that are inundated by the 100 -year flood with flood depths of only one to three feet. These areas are generally flooded by low velocity sheet flows of water. Hazard Mitigation Plan 12018 Gen eial HaZa�r-d Overvie ws I Flood Flazards Definitions of FEMA Hood Zone Designations Flood zones are geographic areas that the FEMA has defined according to varying levels of flood risk. These zones are depicted on a community's Flood Insurance Rate Map (FIRM) or Flood Hazard Boundary Map. Each zone reflects the severity or type of flooding in the area. Modenate to Low Ris-k Areas In communities that participate in the NFIP, flood insurance is available to all property owners and renters in these zones: Area of moderate flood hazard, usually the area between the limits of the 100 -year and 500- B. and X year floods. B Zones are also used to designate base floodplains of lesser hazards, such as (shaded) areas protected by levees from 100 -year flood, or shallow flooding areas with average depths of less than one foot or drainage areas less than I square mile. Area of minimal flood hazard, usually depicted on FIRMS as above the 500 -year flood level. C and X Zone C may have ponding and local drainage problems that don't warrant a detailed study or (unshaded) designation as base floodplain. Zone X is the area determined to be outside the 500 -year flood and protected by levee from 100 -year flood. H�gh Risk Areas In communities that participate in the NFIP, mandatory flood insurance purchase requirements apply to all of these zones: Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30- A year mortgage.

Undeten-mined Risk Areas Genera/ Hazard Overviews I Flood 1--k-)zanls i Darn I allure Hazards Hazard Characteristics Definition Dams are man-made structures built for a variety of uses including flood protection, power, agriculture, water supply, and recreation. When dams are constructed for flood protection, they usually are engineered to withstand a flood with a computed risk of occurrence. For example, a dam may be designed to contain a flood at a location on a stream that has a certain probability of occurring in any one year. If a larger flood occurs, then that structure will be overtopped. Overtopping is the primary cause of earthen dam failure in the United States. Failed dams, can create floods that are catastrophic to life and property as a result of the tremendous energy of the released water. A catastrophic dam failure could easily overwhelm, local response capabilities and require mass evacuations to save lives. Dams typically are constructed of earth, rock, concrete, or mine tailings. Two factors that influence the potential severity of a full or partial dam failure are the amount of water impounded and the density, type, and value of development and infrastructure located downstream. Dam failures can result from any one or a combination of the following causes: ✓ Prolonged periods of rainfall and flooding, resulting in excess overtopping flows ✓ Earthquake ✓ Inadequate spillway capacity, resulting in excess overtopping flows ✓ Internal erosion caused by embankment or foundation leakage or piping * Improper design * Improper maintenance V Negligent operation V Failure of upstream dams on the same waterway Since 1929, the State of California is responsible for overseeing dams to safeguard life and property (California Department of Resources, 1995). This legislation was prompted by the 1928 failure of St. Francis Dam. In 1965, the law was amended to include off stream storage reservoirs due to the 1963 failure of Baldwin Hill Reservoir. In 1973, Senate Bill 896 was enacted to require dam owners, under the direction of Cal OES, to show the possible inundation path in the event of a dam failure. Governmental assistance could be required and continued for an extended period. These efforts are required to remove debris and clear roadways, demolish unsafe structures, assist in reestablishing public services and utilities, and provide continuing care and welfare for the affected population including, as required, temporary housing for displaced persons. Hazard Mitigation Plan 12018 General Hazard Overviews I Dam Failure Hazards Windstorm Hazards Hazard Characteristics Santa Ana wind conditions results in two general disaster conditions. The most common is fire fanned by the high winds. This was the situation in 1993 in Laguna Beach when a massive fire destroyed a number of homes in the surrounding hills. Wind driven flames again caused the destruction of more than 3,000 homes in Southern California in October of 2003. Other forms of disaster would be direct building damage, damage to utilities and infrastructure as a result of the high winds. This has occurred in the past few years in many southland communities including Los Angeles County. Santa Ana winds commonly occur between October and February, with December having the highest frequency of events. Surnmerevents are rare. Wind speeds are typically north to east at 35 knots through and below passes, and canyons with gusts to 50 knots. Stronger Santa Ana winds has gusts greater than 60 knots over widespread areas, and gusts greater than 100 knots in favored areas. Frequently, the strongest winds in the basin occur during the night and morning hours due to the absence of a sea breeze. The sea breeze which typically blows onshore daily, can moderate the Santa Ana winds during the late morning and afternoon hours. Santa Ana winds are an important forecast challenge because of the high fire danger associated with them. Also, unusually high surf conditions on the northeast side of the Channel Islands normally accompany a Santa Ana event. The Beaufort Scale below, coined and developed by Sir Francis Beaufort in 1805, illustrates the effect, that varying wind speed can have on sea swells and structures: '11 aNe: Boaufort Scale (Source : NOAA Storm Genter) r'Lmopf/ U . . . . . . . . . .

In addition, the City is increasingly concerned with "global warming" ramifications and potential increases in wind related events., What are Santa Ana Winds.? "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 and in the Los Angeles and Orange County basins. Santa Ana winds often blow with exceptional speed in the Santa Ana Canyon (the canyon from which it derives its name). Forecasters at the National Weather Service offices in Oxnard and San Diego usually place speed minimums on these winds and reserve the use of "Santa Ana" for winds greater than 25 knots." These winds accelerate to speeds of 35 knots as they move through canyons and passes, with gusts to 50 or even 60 knots. "The complex topography of Southern California combined with various atmospheric conditions create 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 Mountains and west of the Rocky Mountains including most of Nevada and Utah). Clockwise circulation around the center of this high-pressure area forces air downslope from the high plateau. The air warms as it descends toward the California coast at the rate of five degrees F per 1,000 feet due to compressional heating. Thus, compressional heating provides the primary source of warming.

Hazard Mitigation Plan 12018 General I-lazard Ovenliewsl Windstorm Hazards These regional winds typically occur from October to March, and, according to most accounts are named either for the Santa Ana River Valley where they originate, or for the Santa Ana Canyon, southeast of Los Angeles, where they pick up speed. What are Tornados? Tornadoes are spawned when there is warm, moist air near the ground, cool air aloft, and winds that speed up and change direction. An obstruction, such as a house, in the path of the wind causes it to change direction. This change increases pressure on parts of the house, and the combination of increased pressures and fluctuating wind speeds creates stresses that frequently cause structural failures. In order to measure the intensity and wind strength of a tornado, Dr. T. Theodore Fujita developed the Fujita Tornado Damage Scale. This scale compares the estimated wind velocity with the corresponding amount of suspected damage. The scale measures six classifications of tornadoes with increasing magnitude from an "FO" tornado to a "F6+" tornado. TaNe� IFujita "t"ornado Damage Scale (Source: NOAH Storm Predictioin Center) Light damage, Some damage to chimneys and TV antennas; breaks twigs off trees; pushes over shallow -rooted trees.

Inconceivable damage. Should a tornado with the maximum wind speed in excess of F5 occur, the extent and types of damage may not be conceived.

Hazard Mitigation Plan 12018 IR Genera/ Hazard Ovenliews I Windstorni Hazards traer Plan an Knl)cfY -129- conwilaills m1crobairsts Unlike tornados, microbursts are strong, damaging winds which strike the ground and often give the impression a tornado has struck. They frequently occur during intense thunderstorms. The origin of a microburst is downward moving air from a thunderstorm's core. But unlike a tornado, they affect only a rather small area. University of Chicago storm researcher Dr. Ted Fujita first coined the term "downburst" to describe strong, downdraft winds flowing out of a thunderstorm cell that he believed were responsible for the crash of Eastern Airlines Flight 66 in June of 1975. A downburst is a straight -direction surface wind in excess of 39 mph caused by a small-scale, strong downdraft from the base of convective thundershowers and thunderstorms. In later investigations into the phenomena he defined two sub -categories of downbursts: the larger macrobursts and small microbursts. IVlacrobursts are downbursts with winds up to 117 mph which spread across a path greater than 2.5 miles wide at the surface and which last from five to 30 minutes. The microburst, on the other hand is confined to an even smaller area, less than 2.5 miles in diameter from the initial point of downdraft impact. An intense microburst can result in damaging winds near 270 km/hr (170 mph) and often last for less than five minutes. Downbursts of all sizes descend from the upper regions of severe thunderstorms when, the air accelerates downward through either exceptionally strong evaporative cooling or by very heavy rain which drags dry air down with it. When the rapidly descending air strikes the ground, it spreads outward in all directions, like a fast -running faucet stream hitting the sink bottom. When the microburst wind hits an object on the ground such as a house, garage or tree, it can flatten the buildings, and strip limbs and branches from the tree. After striking the ground, the powerful outward running gust can wreak further havoc along its path. Damage associated with a microburst is often mistaken for the work of a tornado, particularly directly under the microburst. However, damage patterns away from the impact area are characteristic of straight-line winds rather than the twisted pattern of tornado damage." Tornados, like those that occur every year in the Midwest and Southeast parts of the United States, are a rare phenomenon in most of California, with most tornado-like activity coming from micro -bursts. What Is Susceptible -to Windstorm? Life and Property Based on the history of the region, windstorm events can be expected, perhaps annually, across widespread areas of the region which can be adversely impacted during a windstorm event. This can result in the involvement of City emergency response personnel during a wide-ranging windstorm or microburst tornadic activity. Both residential and commercial structures with weak reinforcement are susceptible to damage. Wind pressure creates a direct and frontal assault on ii Hazard Mitigation Plan 12018 General Hazard Oven/ioiw3 I Windsionn Hazards a structure, pushing walls, doors, and windows inward. Conversely, passing currents creates lift suction forces that pull building components and surfaces outward. With extreme wind forces, the roof or entire building can fail causing considerable damage. Debris carried along by extreme winds can directly contribute to loss of life and indirectly to the failure of protective building envelopes, siding, or walls. When severe windstorms strike a City, downed trees, power lines, and damaged property can be major hindrances to emergency response and disaster recovery. Utilities Historically, falling trees are the major cause of power outages in, the region. Windstorms such as strong microbursts and Santa Ana Wind conditions cause flying debris and downed utility lines. For example, tree limbs breaking in winds of only 45 mph can be thrown over 75 feet, overhead power lines are damaged, even in relatively minor windstorm events. Falling trees bring electric power lines down to the pavement, creating the possibility of lethal electric shock.

During wet winters, saturated soils cause trees to become less stable and more vulnerable to uprooting from high winds. Increased Fire, Threat Perhaps the greatest danger from windstorm activity in Southern California comes from the combination of the Santa Ana winds with the major fires that occur every few years in the urban/wildland interface. With the Santa Ana winds driving the flames, the speed and reach of the flames is even greater than in times of calm wind conditions. Transportation Windstorm activity impacts local transportation in addition to the problems caused by downed trees and electrical wires blocking streets and highways. During periods of extremely strong Santa Ana winds, major highways can be temporarily closed to truck and recreational vehicle traffic. However, typically these disruptions are not long lasting, nor do they carry a severe long term economic impact on the region. a Hazard Mitigation Plan 12018 General Flazard Overviews I Windstonn lazards ENR Drought 1-lazards Hazard Chavacteristics Definition; Drought is defined as a deficiency of precipitation over an extended period of time, usually a season or more. This deficiency results in a water shortage for some activity, group, or environmental sector. Drought should be considered relative to some long-term average condition of balance between precipitation and evapotranspiration (i.e., evaporation + transpiration) in a particular area, a condition often perceived as "normal". It is also related to the timing (e.g., principal season of occurrence, delays in the start of the rainy season, occurrence of rains in relation to principal crop growth stages) and the effectiveness of the rains (e.g., rainfall intensity, number of rainfall events). Other climatic factors such as high temperature, high wind, and low relative humidity are often associated with it in many regions of the world and can significantly aggravate its severity. Drought should not be viewed as merely a physical phenomenon or natural event. Its impacts on society result from the interplay between a natural event (less precipitation than expected resulting from natural climatic variability) and the demand people place on water supply. Human beings often exacerbate the impact of drought, Recent droughts in both developing and developed countries and the resulting economic and environmental impacts and personal hardships have underscored the vulnerability of all societies to this "natural" hazard. One dry year does not normally constitute a drought in California but serves as a reminder of the need to plan for droughts. California's extensive system of water supply infrastructure - its reservoirs, groundwater basins, and inter -regional conveyance facilities - mitigates the effect of short-term dry periods for most water users. Defining when a drought begins is a function of drought impacts to water users. Hydrologic conditions constituting a drought for water users in one location may not constitute a drought for water users elsewhere, or for water users having a different water supply. Individual water suppliers may use criteria such as rainfall/runoff, amount of water in storage, or expected supply from a water wholesaler to define their water supply conditions. Many governmental utilities, the National Oceanic and Atmospheric Administration (NOAA), and the California Department of Water Resources, as well as academic institutions such as the University of Nebraska -Lincoln's National Drought Mitigation Center and the National Drought Mitigation Center, generally agree that there is no clear definition of drought. Drought is highly variable depending on location., DrOLght Threat The region's Mediterranean climate makes it especially susceptible to variations in rainfall. Severe water shortages could have a bearing on the economic well-being of the community. Comparison of climate (rainfall) records from Los Angeles with water well records beginning in 1930 from the San Gabriel Valley indicates the existence of wet and dry cycles on a 10 -year scale as well as for much longer periods. The climate record for the Los Angeles region beginning in 1890 suggests drying conditions over the last century. With respect to the present day, climate data also suggests that the last significant wet period was the 1940s. Well level data and other sources seem to indicate the historic high groundwater levels (reflecting recharge from rainfall) occurred in the same decade. Since that time, rainfall (and groundwater level trends) appears to be in decline. This slight declining trend, however, is not believed to be significant. Climatologists compiled rainfall data from 96 stations in the State that spanned a 100 -year period between 1890 IMF Hazard Mitigation Plan 12018 Genelral hiazaid Ovewiews I Drought 1-lazards =A and 1990. An interesting note is that during the first 50 years of the reporting period, there was only one year (1890) that had more than 35 inches of rainfall, whereas the second 50 -year period recording of 5 -year intervals (1941, 1958, 1978, 1982, and 1983) that exceeded 35 inches of rainfall in a single year. The year of maximum rainfall was 1890 when the average annual rainfall was 43.11 inches. The second wettest year on record occurred in 1983 when the State's average was 42.75 inches. The driest year of the 100 -year reported in the study was 1924 when the State's average rainfall was only 10.50 inches. The region with the most stations reporting the driest year in 1924 was the San Francisco Bay area. The second driest year was 1977 when the average was 11.57 inches. The most recent major drought (1987 to 1990) occurred at the end of a sequence of very wet years (1978 to 1983). A study that documented annual precipitation for California since 1600 from reconstructed: tree ring data indicates that there was a prolonged dry spell from about 1755 to 1820 in California. Fluctuations in precipitation could contribute indirectly to a number of hazards including wildfire and the availability of water supplies. Gemeral Situation Figure: Water Supply Conditions below illustrates several indicators commonly used to evaluate California water conditions. The percent of average values are determined for measurement sites and reservoirs in each of the State's ten major hydrologic regions.

Although droughts are sometimes characterized as emergencies, they differ from typical emergency events. Most natural disasters, such as floods or forest fires, occur relatively rapidly and afford little time for preparing for disaster response. Droughts occur slowly, over a multiyear period. There is no universal definition of when a drought begins or ends. Types of Drought There are four different ways that drought can be defined: (1) Meteorological - a measure of departure of precipitation from normal. Due to climatic differences what is considered a drought in one location may not be a drought in another location. (2) Agricultural - refers to a situation when the amount of moisture in the soil no longer meets the needs of a particular crop. (3) Hydrological - occurs when surface and subsurface water supplies are below normal. (4) Socioeconomic - refers to the situation that occurs when physical water shortage begins to affect people. Hazard Mitigation Plan 12018 General Hazai d Overviews [ Drought Flazarcls Historical Califbmia D -oughts A significant drought, reported by many of the ranchers in southern California, occurred in 1860. The great drought of the 1930s, coined the "Dust Bowl," was geographically centered in the Great Plains yet ultimately affected water shortages in California. The drought conditions in the plains resulted in a large influx of people to the west coast. Approximately 350,000 people from Arkansas and Oklahoma immigrated mainly to the Great Valley of California. As more people moved into California, including Los Angeles County increases in intensive agriculture led to overuse of the Santa Ana River watershed and groundwater resulting in regional water shortages. Several bills have been introduced into Congress in an effort to mitigate the effects of drought. In 1998„ President Clinton signed into law the National Drought Policy Act, which called for the development of a national drought policy or framework that integrates actions and responsibilities among all levels of government. In addition, it established the National Drought Policy Commission to provide advice and recommendations on the creation of an integrated federal policy. The most recent bill introduced into Congress was the National Drought Preparedness Act of 2003, which established a comprehensive national drought policy and statutorily authorized a lead federal utility for drought assistance. Currently there exists only an ad-hoc response approach to drought unlike other disasters (e.g., hurricanes, floods, and tornadoes) which are under the purview of FEMA. Droughts exceeding three years are relatively rare in Northern California, the source of much of the State's developed water supply. The 1929-34 droughts established the criteria commonly used in designing storage capacity and yield of large Northern California reservoirs. The driest single year of California's measured hydrologic record was 1977. According to USES, California's most recent multi-year droughts occurred between 1987-92, 2006-2010 and 2012-2016. Past Calihmnia DroLfghts The historical record of California hydrology is brief in comparison to the time period of geologically modern climatic conditions. The following samplings of changes in climatic and hydrologic conditions help put California's twentieth century droughts into perspective, by illustrating the variability of possible conditions. Most of the dates shown below are approximations, since the dates must be inferred from indirect sources. 11, 000 years befoie present Beginning of Holocene Epoch- Recent time, the time since the end of the last major glacial epoch. 6,000 years before. present Approximate time when trees were growing in areas now submerged by Lake Tahoe.

Norse colonies in Greenland failed near the start of the time period, as conditions became too cold to support agriculture and livestock grazing. The Anasazi culture began to decline about 1300 and had vanished by 1600, attributed in part to drought conditions that made agriculture infeasible. Mid -1500s, . D. Severe, sustained drought throughout much of the continental U.S., according to dendrochronology. Drought suggested as a contributing factor in the failure of European colonies at Parris Island, South Carolina and Roanoke Island, North. Carolina. '1850sAR Sporadic measurements of California precipitation began. Long-term stream flow measurements began at a few California locations. Of the many varied indexes used to measure drought, the "Palmer Drought Severity Index" (PDSI) is the most commonly used drought index in the United States. Developed by meteorologist Wayne Palmer, the PDSI is used to measure dryness based on recent temperature compared to the amount of precipitation. It utilizes a number range, 0 as normal, drought shown in terms of minus numbers, and wetness shown in positive numbers. The PDSI is most effective at analyzing long-range drought forecasts or predications. Thus, the PDSI is very effective at evaluation trends in the severity and frequency of prolonged periods of drought, and conversely wet weather. The National Oceanic and Atmospheric Administration (NOAAA) publish weekly Palmer maps, which are also used by other scientists to analyze the long-term trends associated with global warming and how this has affected drought conditions. The University of Nebraska -Lincoln has published many of these Palmer Drought Index maps analyzing trends over the past one hundred years (National Drought Mitigation Center 2045; Figure 1). In coastal southern California, from 1895 to 1995, severe draughts occurred ten to 15 percent of the time.. From 1990 to 1995, severe droughts occurred ten to 20 percent of the time and as recently as 1989, a severe drought was documented that lasted for six years. More recently, between 1999 and 2004, a six-year drought on the Colorado River basin has resulted in a drawdown of Colorado River water storage by more than 50 percent. Based on these trends, severe droughts can readily occur in southern California. According to the California Natural Resources Conservation Service (NRCS), the current drought in southern California has caused extensive devastation to forests in the mountains of San Bernardino, San Jacinto and Palomar Mountains. Drought weakens trees which make them susceptible to infestation by bark -beetles.. In turn dry vegetation and beetle infested trees are more susceptible to fire than healthy forests.
