Grigsby, City Manager Date: August 16, 2012 Initiated By: Dana McDaniel, Deputy City Manager/Director of Economic Development Re: Resolution 44-12 - Franklin County Natural Hazards Mitigation Plan Update Background The Federal Emergency Management Agency requires local communities to adopt a natural hazards mitigation plan as a condition of eligibility to receive federal funds available through the agency. Franklin County Emergency Management and Homeland Security (FCEM&HS) first adopted a plan five years ago and for the past year has been working on an update to the plan. It now needs its member communities to adopt the plan update. The Natural Hazards Mitigation Plan Update was completed by FCEM&HS with a committee of multi -disciplinary subject matter experts from across the county and representatives from all 42 jurisdictions. The Natural Hazards Mitigation Plan Update is designed to serve as a guide to local jurisdictions on efforts to mitigate the loss of life and property from natural hazards faced by Franklin County. It contains details on hazards and possible strategies to reduce their impacts. Each jurisdiction was invited to participate by creating projects individualized for their specific needs to reduce the impact of hazards on its citizens. The Natura/Hazards Mitigation Plan Update has been approved by the Ohio Emergency Management Agency and the Federal Emergency Management Agency and now must be adopted by the Franklin County Board of Commissioners and all cities and villages in Franklin County. This plan must be adopted by formal resolution voted on by City Council to meet applicable legal requirements. The City is not required to take any actions or fund any projects identified in the plan. The plan serves as a guide to mitigation actions, but is not a mandate to act. Adopting the plan assures the City's eligibility to receive federal mitigation funds as they become available. Communities not participating in the County plan are required to complete their own plans in order to receive funds. Recommendation Staff recommends Council approval of Resolution 44-12, adopting the Natura/Hazards Mitigation Plan Update. �v1� SOU EMCTgenCy 'Management and 1Hlumrne➢and Security ONTO Michael R.

The Mitigation (flan has been approved by the Ohio Emergency Management Agency and the Federal Emergency Management Agency and now must be adopted by the (Franklin County Board of Commissioners and all Cities and Villages in Franklin County. Townships may adopt the plan as a show of support for countyide mitigation, and we welcome the support. However, adoption by the County [hoard of Commissioners is considered adoption on behalf of the townships. This plan must be adopted by formal resolution voted on by the governing body of your jurisdiction in order to meet applicable legal requirements. Adoption of this plan ensures your jurisdiction is eligible to receive federal mitigation grant dollars as they become available. Were it not for their participation in the County plan, each jurisdiction would be required to complete its own mitigation plan to receive funds. We thank you on advance for your participation with us as we finalize this important plan. What does `adoption' really mean? Adoption of the Franklin County Natural Hazards Mitigation Plan is C,Jtical and means: We are in compliance with the Disaster Mitigation Act of 2000 (DMA2K). DMA2K requires local jurisdictions adopt the plan in order to be eligible to receive federal mitigation grant funds. • You have the opportunity to advocate the plan, encourage mitigation and implement building standards for hazard areas in your jurisdiction. © You value mitigation by supporting the mitigation projects created in your jurisdiction. Adoption does not mean you agree to take any actions or fund any projects identified in the plan. This plan serves as a guide to mitigation actions and is in no way a mandate to act.

Mapping Annex Risk Assessment all Mitigation Plan The Franklin County Natural Hazards Mitigation Plan was first developed and adopted for implementation by Franklin County, Ohio in 2007. This version serves as the 2012 update. This plan must be updated and adopted by all particrisdictions every 5 years. Historical information shows that Franklin County is at risk of damage from a variety of natural hazards: flooding, severe winter weather, tornadoes, severe summer storms, drought, and invasive species. This plan explains a��orous analysis of t e potential effects of these natural hazards on the structures a Krastrncture with Franklin County and proposes measures to reduce the risk of a natural hazard leading aster including property loss, business disruption, or n loss of lif . Most recently Franklin County has experienced severe winter sand severe su r storms, but history demonstrates that Franklin Count seep ible to floodin and damage resulting from high winds or tornadoes. nted Presidential Disaster Declarations for Franklin County um the County's su ility to in types of natural hazards as seen in Table 1 b lthough it is impo to predict when these disasters may occur, planning and c operation mak le to minimize the effects of natural disasters.

Real estate parcels located in floodplains and floodways were identified by the Franklin County Auditor, repetitive flood loss data in Franklin County was obtained from the Federal Emergency Management Agency (FEMA), and maps were created using the Franklin County Emergency Management & Homeland Security (FCEM&HS) Geographic Information System IS). Several regional development plans served as resources, as well as local jurisd c floodplain management and zoning standard guidelines. Finally, historical information provided by the National Weather Service, Franklin County publications and loca library research were included in the final document. The Risk Assessment for Franklin County serves as the found% n for the and risk data found in this plan. This document details risks4faced by Franklin County including detailed histories and impacts. Pleas e Attachment # 2 for a copy o is document. 1.1 Purpose of the Plan As the cost of natural disasters c tinues to rise, FEMA lemented programs to identify effective ways to reduce n bility from disa With FEMA grant assistance, Franklin County has bee blydinate the cr natural hazards mitigation plan to assist communitiesore e their risk from ral hazard events. This natural hazards mitigation plan is used to develop strate Ls risk reduction and to serve as a guide for all mitigation activities throughout the Cou This plan inc s a lis on items deve ed by the Local Mitigation Core Group to reduce ris natura azards through blic education and outreach, new and enhance s and implementation of p ative activities. Fra ounty is highly urbanize y It a population that exceeds one million sists of 15 cities, 9 -v'ffWs and 17 townships. All Franklin County jurisdictioiI91110hipated in the development of this plan and are considered throughout Although the p oes not eish development requirements, the background information and r ces pro ided in the plan are useful in determining land use strategies in un-dev ed areas of incorporated and unincorporated parts of Franklin County. All mitigati efforts are local, and the primary responsibility for development and land use policie curs at the local level. Adoption ofUran ensures Franklin County and participating jurisdictions continue to remain eligibylo apply for and receive Federal mitigation grant funds administered by the State of hio on behalf the Federal Emergency Management Agency (FEMA). This plan complies with the requirements set forth in the Disaster Mitigation Act of 2000 and its implementing regulations published in Title 44 of the Code of Federal Regulations (CFR) Section 201.6. 1.2 Organization of the Plan 1.2.1 Action Plan Strategies The initial development of the Franklin County Natural Hazards Mitigation Action Plan was in response to the passage of the Disaster Mitigation Act of 0 (DMA2K). DMA2K is a federal effort to stem the losses from disasters, reduipRETNpublic and private expenditures, and to speed up response and recovery from disasters. The act establishes a requirement for local governments to prepare a Natural H arc Plan in order to be eligible for mitigation related funding from FEMA. The Franklin County Natural Hazard Mitigation PlAias eveloped blueprint for coordinating a countywide planning process that promotes from a wide variety of organizations, disciplines and representatives of the while complying with the DMA2K. The plan identifies the hazards that can county and our vulnerability to these events. The plan includes countywide mitigation goals and strai�gies as well as loca based projects. The next phase o itigation planning will be to continue working with individual local jurisdictions on ng local mitigation strategies and activities, using the ODNR Structure Inventory 1111 ly update the local risk Asessments, and coordinate local mitigation strategNwi anklin Co)y Natural Hazards Mitigation Plan. 1.2.2 Original Plpment V IF This plan was originally completed and adopted in 2007 using a countywide approach. Franklin County has 42 separate jurisdictions, mad1pup of cities, villages, and townships and County government. In 1988 all jurisdictions in Franklin County entered into an agreement establishing a countywmergency management agency as provided for in Revised Code Section 550 . This agreement states: "...the Franklin County mergency Management Age cy, being hereby established, shall perform the service of coordinating the emergency e ent activities of Franklin County and the political subdivisions which enter into t agreement..." and ..."the (individual jurisdiction e) desires to enter into is agreement with the Franklin County Board of o missioners and the Chie Executives of the other political subdivisions within Franklin County. All jurisdictions w f nvited to participate in plan development and the creation of the mitigation strategy. The original plan included all Franklin County jurisdictions with the exception of theVCity of Westerville, which was at the time a Project Impact Community. All participating jurisdictions were asked to adopt the plan and all did- including each township that participated. The Franklin County Natural Hazards Mitigation Plan is the result of a collaborative effort between Franklin County citizens, public agencies, the private sector and regional planning representatives. 0 1.2.3 Update Development Franklin County applied for and received Hazard Mitigation Grant Funding (FY2010) to prepare the FEMA required update of the Franklin County Natural Hazards Mitigation Plan. Work began on this plan update in March of 2011 with the first Core Group Meeting. During the March 2011 Core Group meeting it was decidednew format would be utilized for greater clarity and organization of the overall Fr lin County Natural Hazards Mitigation plan. The FEMA Mitigation Crosswalk was utilized throughout this planning process to ensure that all of the requirements were met. The plan is formatted in such a way that it follows the Cros alk to make the State and Federal review process easier. _ Since the creation of the original plan, the Mitigation Grant Funding to develop a strate Whitehall. That document has been incorp� will be used by the City in conjunction w repetitive flooding issue in the area. WhiiMhall received 7 uate tooding within th this p as Addendum an to ess and mitil The City of Westerville had a starone mitigation plan created in 2007, but is included as part of the Franklin County Natu ds Mitigation Plan for this update. After this mitigation plan is approved, Westery t the plan and will be.001isidered part of the Franklin County Natural Hazards tiga The City of W terville's Hazards Mitigation Plan was used in the up proc plan and was used in the coordination of Westerville's Action Ite 1.2.4 Imple ation, ring and Evalilation The Plan ai*nance Section of this documeils the process to keep the Franklin County Natural'Hazards Mitigatign Plan an ac document.

The Franklin County Board of Commissioners and part icliuffrisdictions will be responsible for re -adopting the Franklin County Natural Hazards—Mitigation Plan upon FEMA approval. These governing bodies have the authority to4advocate the plan, encourage and promote natural hazard planning, and implement building standards for hazard areas identified within their boundaries. 9 Economic Analysis of Mitigation Projects The Federal Emergency Management Agency's approach to natural hazard mitigation strategies typically involves a benefit/cost analysis. Conducting benefit/cost analysis for a mitigation activity can assist communities to determine whether a project is worth undertaking now to avoid disaster related costs later. Determm the economic feasibility of mitigation projects provides decision -makers with a which to compare alternative projects. Public Involvement FCEM&HS will be responsible for plan mainteriancejonoLuNn and public comments. FCEM&HS will continue to include public com nts anR suggestions into reviews and/or updates of the All Natural Hazards Mitigation Plan. his plan will be housed on the FCEM&HS website for download by the public at any tim 1.2.5 Evaluation of the Plan Plan Outline To make the plan easier to follow and to have a more comprehensi)iit*nalysis of each hazard, this updated plan references tj Franklin County 2010 Risk Assessment that was created by Franklin County Emergency Management and Homeland Security.

Officials of Delaware, Licking, Fairfield, Pickaway, Madison, and Union counties were notified and invited to participate in the planning process. While none of these neighboring counties participated in plan development, each is aware of the planning effort. Franklin County has existing mutual aid agreements withCalso e adjacent counties and works with representatives regularly. A lettert to these counties on August 11, 2011 to notify them ofthe planning erticipation and comment. The letter can be found in Appendix II. As part of the update, the Core Group decidZthistlisn e t1 plan to simpler to follow. Another item that was addressed i eluded reviews 2010 Risk Assessment. The Core Group utilized Assessment to help e the hazards addressed in this plan. At the second Core Group meeting the group went t of th�short term andRong term action items and made reference to the status h one. Action items were approved to be prioritized basethat the existing hazar ng from the 2010 Risk Assessment. The consensus was th t ction items would oritized based off the ranking of the hazards. Therefore, all t ng action items would liave the greatest priority since flooding is the highest nki The group�o discussed current land use trends within Franklin County. 2.2.2 2011 Jurisarticipation During the process of updating the plan, ea eeting of the Core Group was open to representatives of participating jurisdictions. ntatives were invited to attend the meetings in person or to send a 'aison to addr any comments or concerns they may have. nMarc 2011, representatives of each organization participated that participated in the previous re Group, as well as pay new organization that would be beneficial to the process were invited by e-mail and certified letter to join a Core Group meeting on April 7, 2011. The meeting include�"an overview of the Risk Assessment, an explanation of the hazard mitJce cess, a description of the Core Group commitment requirements to the plan uphe update process of the action items. During this meeting the group supporteto the plan format to increase organization and improve clarity. Meeting minutas a list of attendees for this meeting and all other Meetings are in Appendix I A meeting for the jurisdictions was held in the morning of May 25, 2011 at the FCEM&HS building. Representatives from each participating jurisdiction were invited by a FCEM&HS official by certified letter, e-mail and telephone to participate in this meetings; a copy of the e-mail invitation, sign -in sheet, and meeting minutes are included in Appendix III. The meeting started with an overview of the previous plan and past 14 action items. Then the representatives joined in to a discussion on the mitigation action items that have been accomplished and emergency operations plans that have been developed in the past 4 years. FCEM&HS contacted jurisdictions not present at this meeting to ensure countywide participation. Jurisdictions were given the opportunity to update their previous action items and to develop new action items by emailing updates to FCEM&HS by June 24, 2011. All jurisdictions participated in the planning process even though the majority were not present at the jurisdictional meeting. Jurisdictions participated by phone or email. The City of Westerville has been added to the plan during this update. One jurisdiction was removed from this plan, the Village of New Rome which was dissince the creation of the plan. 2.2.3 2011 Public Involvement A notice about updating the Franklin County Natuul Hazards Mitigation Plan was pojFd on FCEM&HS's website throughout the planning process which is included in AppAdix IV. Residents of Franklin County, volunteer watershed groups, and neighboring communities with an interest in trocess were invited to contact the Franklin County Mitigation Officer and were invite cipate in the process through plan comment or attendance at meetings. An invitation to t blic to review and ent on the draft plan was posted on the home page Fra my Emerge Management and Homeland Security's Website on 11/10/11 an onlin oughout the entire process. A screen shot of the Web page is lisp d in IV. I FCEM&Xpease ess release in ng review nd comment on the plan on 11/10/11lease was sent to all dia outlets and all local jurisdictions. A copy oft is displayed in Appen er receiving anressing pu group comments, the draft of the updated teI Non FCEM& e for final public comment. Once approved, plan de available to the public in its final form. Other Planning isms During the process pdatmg the plan, the consultant coordinated with the Franklin county Planning De ment and the Core Group by reviewing the existing planning mechanisms to as ain community capabilities and identify opportunities for implementing miti on actions. Documents consulted included existing municipal and county zoning subdivision regulations and flood damage prevention ordinances; the existing comp ensive plans; county building code; and Flood Insurance Rate Maps, which were revised in 2008 and are currently continuing to the review as part of the FEMA Map Modernization Program. 15 Gathering New Data Gathering and analyzing new data about natural hazards and the community was critical to the process of updating the plan. New data used for the plan are identified throughout the plan; however, because flooding is both the most common and the most costly natural hazard that occurs in Franklin County, particular attention was provide athering new data about structures that have been damaged repeatedly by flood'n The first step in the process of gathering data to fully understand the problem of repetitive flood losses was for FCEM&HS to request data about repetitive flood loss properties from the Federal Emergency Management en Region,V. This data is made available to the local community by FEMA andeprevious flood insurance claim payments made for buildings and contents, e locations of the structutaks that policies cover, base flood elevations at those locations, as well as information about construction dates, number of floors, type o0tructre, and *aunt of money provided previously through insurance claims. IL e The second step in the process was to review the data ded by FEMA to reconcile any discrepancies between prope ddresses provided by and those found in the Franklin County Geographic Infor stems (GIS) info A third step was utilize a software elo EMA and the tional Institute of Building Sciences (NIBS) call HAZ S. HAZUS is a program that is capable of simulating a designed scenario to identify the losses and potential risks associated with 16 3.1 Planning for Natural Hazards in Franklin County Natural hazards impact citizens, property, the environment and the eco of Franklin County. Franklin County is susceptible to flooding, high winds, tornadoes, ere winter storms, droughts, periods of intense heat, and earthquakes.

The National Flood Insurance Pro g FIP) Community System (CRS) was implemented in 1990 as a progr nizing and en mg community floodplain management activities that ceed them um NFIP standards. Under the CRS, flood insurance premium rates e adjusted reflect the reduced flood risk resulting from community activities tha eet the thre oals of the CRS: (1) reduce flood losses; (2) facilitate accurate insura e rating; and 43fpromote the awareness of flood insura e. Discounts on premiums ay range from 5% to 45% based on the actions to in each community.

Between 1964 and 2011, nine al disaster declarations have been declared in Ohio for flooding, high wind damaoes and severe winter weather. The late spri and early summer is when Franklin County traditionally experiences high wind and tornado activity. Two deaths have been recorded from tornadoes in Franklin County since 1916. Since 1950, more accurate information regarding injuries to citizens and damage to property has been recorded. Seven injuries were reported from a tornado in Franklin County on February 22, 1971, and nine injuries reported from tornadoes occurring in May 1973. 17 In January 1978, Franklin County experienced record cold and snowfall totaling more than 34 inches. The blizzard of 1978 began as rain and changed over to snow, resulting in more than 10 inches of snow. Wind gusts up to 69 MPH contributed to significant blowing and drifting of snow across much of the county. January 1978 holds the monthly snowfall record in Franklin County at 34.4 inches. The coldest winter season (December through February) occurred in 1976/1977, with an average temperatur 20.9 degrees. Prior to 1978, Franklin County had not experienced this level of snoWffffNSTjV1910. 2 Franklin County is predominantly urban, encompasses 543 square miles and consists of 42 jurisdictions.

Central Ohio continues to experience steady development, as well as shifts in the distribution of population and jobs in the region. Historically, ethe h in central Ohio has occurred in a radial pattern, with population moving oucentral city, to the inner suburbs and then to outer suburban areas. Beand 2009 Delaware County, just north of Franklin County, grew by 54.10rowth rate of any county in Ohio. Based on U.S. Census figures, Franklin County has xpienced s�population growth and can expect continued development and popu atio growth. After the 1990 and 2000 U.S. Census, Franklin County's population totaled 961,437 and 1,068,978, respectively. Based on 2010 U.S. Census figures, the co ty's population surpassed 1,163,414, an 8.1 percent increase. This growth rate is co rable to the 10 percent growth between 1990 and 2000. Other notable informatio ted to population in Franklin County is the fact that the age group from 20-24 years is t e largest. The large number of residents in this category can most likely be attributed to the presence of The Ohio State University. The cottity also continues to exp, ' nc, an increase in the number of residents aged 62 or older. Ink erms of race and Franklin County is experiencing steady increases in populaf all minority ost notably the Hispanic and Somalian communities.

Unincorporated areas are subject to zoning regulations adopted by the Franklin County Board of Commissioners or local townsl*Ts, and are enforced by the Franklin County Economic Development and Planning Department or township zoning officials. Most of the new development in central Ohio is occurring near or outside of the I-270 outer -belt. Despite significant development in the downtown area, rapid suburban 22 development has reduced the central city's "market share" of regional population and jobs. In addition, the "inner ring" suburbs (Upper Arlington, Bexley, Whitehall and Grandview Heights) are losing their market share of non-residential tax base to new development in the newer city and suburban county. An analysis of the population statistics in Table 2 reflects an enormous amount of growth during the last 10 years in younger municipalities in Franklin County, most notably the Cities New Albany, Dublin and Grove City. With the exception of the City of Columb o the older, land -locked municipalities have experienced little to no growth. This trend is also reflected in the population of unincorpora owns reas of Franklin County in Table 4. Although significant growth as curred many of the unincorporated townships, the decrease of popula ' these area results from annexation of the unincorporated areas to a municipa y. example of this is reflected in the 89% decrease in population of Washington Township between 1990 and 2000. Large portions of Washington Township we * -annexed to the City of Dublin during t 10 year period. Significant housing development and constructio m the City of Dub n during this period contributed to a 40% increase in its population. 3.4.2 Community Development & Annexation The stable, yet diverse economy of Franklin County has contributot to the strong business and residential growth it ha experienced over the past decade. As home to Ohio's Capital, government employ t accounts for approximately 16% of the workforce in Franklin County. The sta ity of the local konomy combined with low interest rates has to a strong re 1 estate market. JV The average sales price o residential ho m Franklin County during 2009 was $153,700. This figure has d re over thecae years with residential properties showing a 3% decrease over ime. There a urrently more than 388,994 real estate parcels in Franklin County a an 4manufactured homes. According to the ounty Auditor, the 2008 esse value of residential real estate in Franklin ounty totals $54.7 billion. Commercial and industrial properties were values at $19.1 billion and $4.04 billion, respectively for a total assessed value of $77.84 billion. The Community anonomi�evelopment (CED) office for Franklin County serves as a representative o e Board of Commissioners on community and economic development issues. e CED office coordinates Housing and Urban Development (HUD) and Communft Development Block Grants (CDBG) for the county to assist with home buyer counseling and down payment assistance. The office also focuses on strengthening business/industry growth in Franklin County by establishing community reinvestment areas and the use of incentives such as tax abatements for expanding businesses. dearly every municipality located in Franklin County employs a community and economic development official, dedicated to focusing on the growth of their community. Ohio's home -rule statute has contributed to many municipalities' ability to plan and prepare for growth in their community. 23 Annexation has had a significant impact on development in Franklin County. The City of Columbus has expanded into developing areas that are more typically in suburban areas. In 1950, Columbus covered 39.9 square miles. By 2007, the city exceeds 213 square miles. During the period covering 1992-98, the City of Columbus acquired 48% of the 22,103 acres annexed in Franklin County. The Village of New Albany annexed 20%; Grove City annexed 10%; and Hilliard annexed 5% of all land anne in the county during this period. The City of Columbus also has a very strong historic preservation community. There are currently 19 historic districts, and 34 individual proper4s listed on the Columbus Register of Historic Places which are overseen by theT istoric Resources Commission. The four primary historic districts formally reco bity Coun Jude the Brewery District, German Village, Italian Village a ictorin Village. 3.4.3 New Development Active development has occurred in newer areas of Columbus. Durinfthe period of 1993 to 1998, more than half of all new singl3wy housing units in Franklin County were located within the er city. Comparatively, only 4% were for homes located in the older city of Columb ti -family housing development continues to be concentrated in the newer city. Muc o evelopment has bated near other newer city development, including TutSe n and Easto Mid -Ohio Regional Planning Commissio (MORPC) has prelWd development forecasts for the Columbu area MORP projects the majdfity of growth in retail and Office develo nt wi r in the northern tier of the region, while new industrial wareho^ha�lt, ribution centers will be located in the southern half of the county.

Greenways Plan The Franklir}County Greenways Plan provides a comprehensive view of river and stream management, focusing on ecological, environmental and conservation interests. However, several recommendations made in the Greenways Plan are consistent with the goals and objectives established in the Franklin County Natural Hazards Mitigation Plan. 24 Recommendations from the Franklin County Greenways Plan that are consistent with the objectives of this plan include: • A more consistent, regional approach to river related development including subdivision, stormwater management, erosion, and sediment control regulations. • Encourage countywide participation in the Community Ratin em (CRS) of the National Flood Insurance Program (NFIP). Currently y Village of Obetz participates in the Community Rating System. • Implementation of a regulatory floodplain for Franklin • Lower tax rates for floodplain properties to en ge o to leave the floodplain in a natural state. 3.5 Capability Assessment The purpose of the Capability Assessment is to identify strengths and weaknesses that will affect the ability of the County and participating jurisdictions to implement mitigation actions. Capabilities de a variety of regul 'ons, existing planning mechanisms, and administrative c provided throu ablished agencies or authorities. 3.5.1 Regulatory Capabilities A zoning ordinance specifies the types f development Rat can occur in particular locations. The Franklin County Zoning R lution applies to unincorporated land in Blendon, Brown, Clinton, Franklin, Hamilt Madison, Mifflin, Norwich, Pleasant, Sharon and Truro Townships. The remainin #*Wnships all have adopted township zoning: Jackson, Jefferson, Perry, Plain, Prairie and Washington Townships. Subdivision re ns further spe ' y how development can occur. Franklin County and all 16 ve adopted qWrvision Regulations. The Franklin County Subdivision Regulations apply to uninqWrated land in all townships. The Franklin Con ecia�Ynictilpalities on NFIP Regulation applies to unincorporated land in all townships. f the in Franklin County participate in the NFIP and have adopted oodplain management ordinance. Greater detail of the participating conuu s and regulatory compliances are located in the flooding section, Section 5.0. Stormwatergement regulations provide for the conveyance of stormwater to decrease floolffig. Stormwater Management requirements are covered in the Franklin County Sub ivision Regulations, Franklin County Zoning Resolution, the township zoning resolutions, and the Franklin County Greenways Plan. Stormwater regulations vary greatly from jurisdiction to jurisdiction and unincorporated Franklin County currently lacks strict stormwater regulations. 25 Adoption and enforcement of building codes ensure that both residential and commercial structures are safe. Every municipality in Franklin County has adopted the 2009 International Code Council (ICC) Family of Model Codes including the 2009 International Residential Code (IRC). A local historic district ordinance enables a community to regulate elopment in a specific, designated area of historic significance. Table 5 identifies planning mechanisms for Franklin Co summarizes the regulatory tools used in Franklin County and partic' ng ctions. These regulations support the goals of this hazards mitigation p n d provide unities for further mitigating the potentially negative effects of n az%ds throu ation.

A list of the number and types of critical infrastructure is shown in Table 6. The locations of many critical facilities and infrastructure are considered protected information under state law so they are listed below in general term Table 6: Critical Facilities or Infrastructure Aap book has been developed to Idencritical facilities and some infrastructure n Franklin County and can be found as Attachment 41 to this plan.

Other plans can support the goals of this hazards mitigation plan and provide opportunities for integrating actions that will mitigate the potentially negative effects of natural hazards with actions designed to achieve other goals. The Mitigation OR Core Group, which has many representatives involved in the planning mechanisms denoted in this plan, suggested a process for incorporating mitigation alternatives and strategies into other existing planning efforts. The process includes coordination between the agencies involved in the developing the planning mechanisms for Franklin County and the participating jurisdictions. As part of their continued commitment to be on the Mitigation Core Group, each member will evaluate the mitigation alte bes, short and long term and the jurisdictional alternatives to potentially add to their e ' ting plans. Many of the plans already denote the Franklin County Mitigation Plan as reference for the County and jurisdictions. As part of the Mitigation Plan monitoring and evaluation efforts the Mitigation Core Group will then validate the incorporation of key mitigation alternatives into the planning mechanisms during the Mit' atioPlan updating process. The Columbus Comprehensive Plan was co m eted nd adopted in 1993. A comprehensive plan is a policy document identifying community goals and objectives for future growth and development. The Plan is intended to serv*& as a guide with which to protect and enhance the quality of life in Columbus. It accomplishes this by fostering orderly, manageable, and cost-effective growth and'establishing alfamework for flfure land use decisions. FCEM&HS was established acco dit Ohio Revised Co RC) Section 5502.26 governing countywide emergency management. The countywi agreement between all 42 jurisdictions in Franklin County establishCEM&HS as the emergency management agency for the entire county was sign 988 and is on file at the offices of FCEM&HS. This Franklin County Emergency Operations Plan (EOP) serves as the legally requirds emergency operations plan for all 42 jurisdictions within Franklin County and i ced by FCEM&HS. The Franklin County EOP addresses Franklin County's planned response to extraordinary emergency situations associated with all hazards such as natural disasters, technological emergencies and acts of civil hostility. When confronted with minor emergency, local agencies routinely carry out their responsibilities independ other agencies or with pre-existing mutual aid ments. However, large-scale ergencies and disasters often create situations equiring Aned, coordinated responses by multiple agencies and jurisdictions. Such disasters and emergencies pose major threats to life and property and have long-term economic, politic and/or environmental implications Emergency Actionns have been prepared according to state law for high hazard dams located in Fra County as well as those for which the inundation area includes parts of Franklin Co . Each Emergency Action Plan addresses ways to safeguard lives and reduce propertamage within the inundation area, procedures for effective dam surveillance; procedures for prompt notification of emergency management officials; warning and evacuation procedures; and emergency response actions that will be taken in the event of potential or imminent failure of the dam. Plans have been prepared, reviewed by Franklin County officials, and are on file at the FCEM&HS Office for the following dams: • Hoover Dam- operated by the City of Columbus • O'Shaughnessy Dam- operated by the City of Columbus 019 • Griggs Dam- operated by the City of Columbus • Delaware Dam- operated by the Army Corps of Engineers • Alum Creek Dam- operated by the Army Corps of Engineers Franklin County and the City of Columbus address regional planning concerns by participating in planning activities with the Mid -Ohio Regional Pla Commission (MORPC). There are currently 52 comprehensive area plans with' e ty, shown in Figure 2. Many are multi -jurisdictional and most address land ssues.

Hazards require different levels of risk assessment depending on the extent of the impact they can have on the community. A hazard that is unlikely to happen (and if it does, causes very little damage) will not require the same level of assessment as one that happens frequently and causes severe damage. 32 Steps in Hazard Identification 1. Identification and classification of hazards. 2. Determination of appropriate risk analysis level, based on potential impact and data available. 3. Identification and characterization of hazard -prone locations. 4. Estimation of the probability of occurrence. AL 5. Estimation of possible magnitude. Hazard identification describes and assesses the frequency of occurrence, at a specific place, at a specific time, and with a specific intensity and duration, for a vulnerable population, property, economy and environment.

According to the Glossary of Meteorology (AMS 2000), a tornado is "a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud." A funnel cloud rotates but has no 33 ground contact or debris and creates no damage. A funnel cloud is not associated with strong winds at the surface. Tornadoes often begin as funnel clouds with no associated strong surface winds; however, not all of these funnel clouds evolve into atomado. Most tornadoes produce strong winds at the surface while the visible funnel is still above ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.

Two events that have caused substantial economic and environmental damage in Ohio are the introduction of zebra mussels into waterways and the incursion of the emerald ash borer, responsible for killing ash trees. 34 Earthquakes Earthquakes are caused by the movement of the earth's crustal plates along faults. Franklin County is not located on a fault line, nor have any epicenters been located in Franklin County. Earthquakes occurring in other areas have been felt in Franklin County; 35 5.1 Flooding Update Because flooding is a site specific hazard, data about the location and types of structures and infrastructure in the County were reviewed to identify changes in filnerability. HAZUS was utilized to generate specific data in relation to flooding risks. Although the FEMA Map Modernization process was completed for Fra m County during the last planning cycle, it was recognized by the leadership in Fr in County that there were significant errors in the mapping products. Currently there i�s an ongoing effort called "Map Modernization" under consideration for the Count) tN re-evaluate the current effective NFIP maps for Franklin County. Since the Risk Map has not taken place yet for Franklin County, the County must utilize the best data for flo in management purposes Information about flood loss was augmented in order to comp y with the modifications of 44 CFR Part 201.6 that became effective in October 2007. Regulations now require that local hazards mitigation plans plat cial emphasis on the mit' ation of Repetitive Loss Structures, which are structures ins e NFIP that have least two paid flood losses of more than $1,000 each in an_ iod since 197 . 5.2 HazardProfile- Floodin 5.2.1 Composite of Franklip County , Franklin has an unusually high numb of stream corridors, more than 330 plus river mil s. act combined with histori ents, general weather patterns and urbanization he tify flood' as the gr est natural hazard threat to Franklin Co Plannin documents clet the City of Columbus, and various d watershed groups, are r enced in this chapter. The Franklin County eenway referenced significantly in this section because many of its objectives are consistent the Franklin County Natural Hazards Mitigation Plan: integrated watershed mana ment, stormwater management and flood control, restricted Le-lopment in inappropriateArrain and increased participation in the Community 11W System (CRS1. In urbanized areas, Cages in stream hydrology caused by stormwater and development related to filling iw ithin the floodplain results in higher quantities of water and changes in peak flows. Affece Franklin County is highly urbanized, this plan has been written by focusing on r s, hazards and vulnerabilities located in four quadrants of Franklin County: no west, northeast, southeast and southwest. The plan will focus on flood, development, and water quality issues relative to each of these areas to provide a more detailed analysis of the problems identified, and provide a basis for the communities located in each region to plan future mitigation strategies. W 5.2.2 National Flood Insurance Program The National Flood Insurance Program (NFIP) was established by the National Flood Insurance Act of 1968, and was strengthened by the Flood Disaster Protection Act of 1973. Both the City of Columbus and Franklin County participate in the National Flood Insurance Program and over 3,000 properties in the county are covered 16this program. Participation in the NFIP ensures affordable flood insurance is availabe ommunity residents in flood -prone areas. In return, communities adopt floodplain regulations into zoning codes that meet minimum criteria established by FEM For example, Columbus requires that buildings, including basement levels, be eleva t least 1.5 feet above the base flood elevation in the floodway fringe. Franklin Co nt zoning requires a minimum elevation of one -foot above the base flood elevaf INLAIthough requirements vary somewhat between the City of Columbus and Fr in Co ty, buildings designed for human habitation and the storage of hazardous materials are prohibited in the floodway. There are currently three jurisdictions in the county that do not participate in the National Flood Insurance Program: Brice, Harrisburg and New Albany. Sine flooding is listed as the number one hazard of concern in Franklin County, the FCEM&PN plans to workCth these communities to bring them into compliance. The Mitigation Core Group alonNFlo alN acknowledges that flooding is the number one conklavirig all the local jurisdictions participate in the Naancritical to reducing the potential damaging effects ofhe County. The short and long term action items as well as the jurisdictional action items support the identification, and prioritization of % compliance the NFIP. A Flood Insurance Rate Map (FIRM) is th fficial map produced by FEMA which delineates where NFIP regulations apply.

The of CR�,are to reduce flood losses and to promote the awareness of flood insurance. mmunrty can benefit from actions it takes above and beyond the Federal minimum req ements of the National Flood Insurance Program. In a CRS participating communi , the cost of flood insurance for residents is reduced by 5% to 45% based on the number of activities it undertakes and the points it receives for those activities. Currently, only the Village of Obetz in Franklin County participates in the Community Rating System. 5.2.4 Waterway Locations All of Franklin County lies within the drainage basin of the Scioto River, which drains directly into the Ohio River. The three other rivers in the county Darby, Olentangy, and 37 Big Walnut, which drain into the Scioto River, the largest of which is the Olentangy River. The Olentangy River, Alum Creek, Big Walnut Creek, Blacklick Creek, and the Big Darby Creek all flow through Franklin County and eventually empty into the Scioto River. The various tributary streams and creeks generally flow north to south, from the west central part of the state towards the Scioto River. Scioto River and Olentar%W River are the largest tributaries in the County. Ad Of the 42 municipalities within Franklin County, the City glifflumBIWthe near west side, has suffered the most severe damage from flooding lvh he levee in 1913. Table 8 shows which tributaries have the pote ' to lead to flooding in particular jurisdictions; there is a potential for floodin;i�ra to rivers and streams in almost all jurisdiction in the county. Please refer to lin Co Map Book located in Attachment 41 for a detailed delineation of unty' d prone areas as well the FEMA designated floodplains.

This is a constant concern within the County upstream of overpass and railroad bridges. It has the potential to trap debris and create m, which was the case along the Blacklick Creek. IVINNINLexacerbate flooding n insignificant rain events into substantial flooding encs pstream of the affected area, while significant rain events can cause large devastation to an even larger area. Floodplain Data Based on data provid y the Franklin County Auditor's Office there are 14,199 parcels, with a total appraisecj lue of $4,132,173,100 located in areas currently identified as the 100 -year floodplain. Typical land use within the floodplain includes agricultural, golf courses, vacant land and single family homes. Public entities, charitable organizations and/or churches make up approximately 75% of the parcels located in the designated floodplain. 14rur cemeteries also fall in the floodplain category, as well as four mobile home parks. Eleven parcels classified as quarries, of which most are located in the predominantly undeveloped south end of Franklin County. As part of the 2011 Franklin County Natural Hazards Mitigation Plan Update it was decided that utilizing HAZUS would benefit Franklin County and the other jurisdictions 0 involved to determine loss estimates for this site specific hazard. These loss estimates are utilized primarily to plan and stimulate efforts to reduce risks from natural hazards and to prepare for emergency response and recovery. Since flooding is a site-specific hazard HAZUS was utilized for this particular hazard in order to generate more specific loss estimations for the planning effort. Although HAZUS was an important component of the flooding analysis r Franklin County it is important to note that Franklin County completed a Risk Assessment in 2010 and this information was utilized throughout this process as the basis of all the analyzes conducted on the hazards in Franklin County and is detailed in Attachment 42. 5.2.7 Analysis An analysis of the parcel data provided by the Franklin C there is a significant amount of undeveloped land located floodplain zones.

Other mitigating concepts include an "impact fee" stormwater utility assessment which is based upon the impervious coverage of the property. khe Darby Creek hed S� water Management Strategies and Standards for New Development, dated uary 2001 and prepared for the Darby Creek Watershed Task Force, recognizes t managing stormwater for new development is critical for the protection and conse ation of the Darby watershed. This planning document encourages communities within the Darby Creek watershed to work with local departments to incorporate mitigation strategies into future development to reduce runoff from impervious surfaces. Suggestions include: • Reduce minimum road requirements. • Allow for the use of "queuing streets", narrow roadways which contain a single travel lane. 40 • Reduce street length by examining alternative street layouts. • Incorporate graded, landscaped islands to receive stormwater runoff from adjacent paved roads. • Utilize dry swales and grass channels to convey and treat stormwater runoff. This planning document also makes recommendations for stream b,&%,:pen space development and post construction stormwater runoff control. The Columbus Comprehensive Plan makes recommendatio concerning stormwater management within the City of Columbus; however si ater management crosses jurisdictional boundaries. As such, The Columbus Comprehensive Plan recommends the Mid -Ohio Regional Planning Commission encourage and promote continued cooperation on issues related to stormwater planning and management. Also, local governments throughout central Ohio should promote the establishme t of regional stormwa er districts, or other cooperative arrangements. 400 00' Finally, the Franklin County Greenways Plan encourages regi nal st dards for rive and watershed related land development regulations. Over three dozen political jurisdictions use a wide array of subdivision,�stormwater management, erosion and sediment control regulations. Developing regional andards for as m these regulations as possible would ensure minimum standa iparian areas istency for the development industry. 5.2.9 Previous Oc*Fra es The worst flood ini County\histoccurred in arch 1913. A levee break flooded the near west side (Franklintoulting in the flooding of more than 4,000 homes and the loslolf5 lives. The second m"boding event occurred in 1959 when high water fromrains on ozen groun caused another levee break. Flooding occ again onar west an sides of Columbus. A review of historic weather events recorded by the National Weather Service from January 1993 through December 2010 indicates that flash flooding occurs most frequently and i4reing enced at various locations countywide. Flash Flood events in Franklin Countyy occyv as a result of heavy rainfall in a short period of time, or snow melts. DaPresidential disaster declarations in Ohio from 1964 through 2011 shows thatn County has been included in six flooding declarations costing more t4im $100 Appendix 14Wall previous hazard occurrences recorded by the NCDC for Franklin County; incl ng flooding, which spans the years 1993 through 2011. Many snow storms incluIre some flash floods; for this analysis, these are presented as both flood and flash flood occurrences. 41 5.2.10 Probability of Future Flooding Using HAZUS, approximately 10.2 percent of the buildings within Franklin County have been determined to be within a flood -prone area with at least a 1 -percent chance of flooding in any given year. In this plan, the term special flood hazard area is used rather than floodplain to clarify that the area under consideration is ident ' on the Flood Insurance Rate Maps as having at least a 1 -percent chance of floodi a iven year. Historically, the area with a 1 -percent chance of flooding in a iven year has been called the "100 -year floodplain." kL Another way of considering the probability of damaging flSoding occurring somewhere in the County is to review past occurrences. The NCDC website identifies a total of 53 significant flood events in Franklin County between 1993 and 2011 for an avge of 2.94 significant flood events per year. This suggests that the probability of od occurring somewhere in Franklin County is over 100 per t ven year. 5.3 Vulnerability Assessment —Flooding 5.3.1 Overview of Vulnerability Flood vulnerability is described in terl infrastructure lay in locations where vulnerability overview of damage due to Summary of ►structures, and 9 provides a CD, estimated sign property damage in Franklin County eaributabl*eooding during the years 1993 through 2011 is $3,860,000. Thus the average annual loss for these 18 years is $3,860,000 / 18 = $214,444. The vulnerability to ding for each jurisdiction is dependent upon the amount of land, the number of criticalWilities, and the number of homes within the floodplain. The first two can be assessed m Attachment 41, E.O.P. Mapping Annex. From this map book the total number 6f critical facilities can be calculated and a visional assessment can be made the amount of land that has the potential to flood. Currently, the number of I ca be calculated based off each jurisdiction. For planning purposes, an estimate can made using the Attachment 41 and the HAZUS information. 5.3.2 Identifying Structures The Ohio Department of Natural Resources (ODNR) developed a statewide GIS map of the identified 100 -year floodplains.

This 100 -year flood hazard area map was combined 42 with aerial photography to identify the structures located within the flood hazard area. Every structure in or near the 100 -year floodplain is identified by a checkmark and is assigned a structure identification number. According to the ODNR Structure Inventory, Franklin County has 11,820 flood -prone structures, more than any other Ohio county. With a median value of ofupied housing units at $116,200, the total estimated value of flood -prone structures is $3,484,000. These numbers are somewhat overstated due to the building of the Franklinton Flood Wall. The maps reflect the 100 -year floodplain prior to the wall construction. Please note that this is one data point and the use of HAZUS as part of the flooding analysis generated different numbers of at -risk structures than th ODNR Structure I ventory. It is still important to know that this tool is out there anc] be updated to rethe more accurate information contained in HAZUS. �� 5.3.3 Plan Update Notes The initial version of this mitigation plan revealed1hav strAtures in the CAnty were located in Special Flood Hazard Areas. Currenfiled using HAZUS shows that 6,270 structures are located i e floodplain anst a 1 -percent chance of flooding in any given year. The d difference in the of structures can be attributed to several factors. 1. The elimination of the hazardNinv uctu ed b the Franklinton Flood Wall. 2. New and urate flood inc rate maps. 3. New an ore rate structurory, 4. Utilization of HAZUS which gives ommunity a very distinct snap shot of structures within site-specific hazard ar h as floodplains. 5.3.4 Exposure of Asting Buildi s Due to Flooding AZUS estimates that there are 386,078 buildings in the region which have an aggregate total replacement value of 91,875 million (2006 dollars, 2011 values are not available in HAZUS). For a 100 -year flood, HAZUS estimates that about 3,930 buildings will be at least moderately damaged. Thi is 1.0 1 % of the total number of buildings in the scenario. There are an estimated ,266 buildings that will be completely destroyed by having over 50% damage to the cture. Table 10, shows an estimated percent of damage to each structure exposed an estimated total damage for each occupancy type within Franklin County that can b xpected from a 100 -year flood event.

Special Flood Hazard Area development regulations relate to the base flood elevation, which is the estimated level of flooding that has a 1 -percent chance of being equaled or exceeded in any given year. Because Special Flood Hazard Area or floodplain development regulations specify that residential structures must be elevated to or above the base flood elevation and commercial structures must either be elevated or flood -proofed to or above this level, the degree to which future structures are exposed to flood damages should be minimal. 45 However, calculations of base flood elevations are based on models that rely upon data about previous flood events; should future floods be greater than those experienced in the past, the base flood elevation may not provide sufficient protection. Therefore a mitigation strategy of this plan includes that communities adopt more stringent Special Flood Hazard Area or floodplain development regulations causing future structures to be built with freeboard, i.e. above the current base flood elevation. AL� 5.3.7 Estimating Potential Loss Methodology The method utilized for estimating potential Losse due historical data provided by NCDC and HAZUS. ages the County have varied from no cost for damage $1.0 mi According to NCDC, estimated property amage in Fra flooding or flash floods over the period 199 provided from NCDC are used to estimate the Estimated Potential Dollar Losses Since the total loss over these $3,860,000 / 18 = $214,444.

In this 2011 update, features of winter storms thaUmay cause damage are treated separately; heavy snow or ice is discussed as one hazard because damage from either of these hazards is due to their weight on power lines and roofs. Damage caused by high winds, another potentially damagi4ature of winter weather, is described in the section about Severe Summer Weather. While temperatures during winter weather can be very low, Franklin County has no history of structural damages due to extremely cold temperatures, and cold temperature has never been considered a hazard for Franklin County. r AVERAGE ANNUAL SNOWFALL (IN INCHES) _ :ft MN Cuswn00/. ••.u_ OO{RN[O wPOa 4Nwan{v !RN NIMRY WRRN YRN �• P l[N!<w MYRPN i XlYOOR }'.1 MMM +L� VM g W61XIif�{ NiM/pl NO{N[{ Oy 14NX04 {PGN j'j NNO% iN!!%Y f y{wNyX!

Rain, freezing rain, ice, snow, extremely cold temperature wind are all associated with severe winter storms. Ice storms can impact trees, power lines and utilities systems. As recently as December 2010, freezing rain resulted in the accumulation of 1/4 to '/2 inch of ice on power lines and tree limbs.

The whole e was covered with nearly two feet of snow and hazardous snow dr ormed all over state. During the period )vering January 1993 to December 2002, there were more than four instances of snow and ice storms resulting in traffic accidents, power outages and trees collapsing. In 1996, Franklin County was under winter storm related warnings five times in the montrof January alone. Damage in 1996 included a roof collapse from heavy snow, and flooding resulting from melting snow. Property damage estimates for these events totaled more than $16 million. There were three instances of extreme cold that resulted in multiple car accidents, burst water pipes, and two deaths from exposure. v' 48 What is being called the blizzard of 2008 was not officially called a blizzard due to wind speeds not reaching 35 mph. However, during this event a record setting 20 inches fell in central Ohio. Port Columbus International Airport had to cancel the majority of the flights on March 8a. This storm system caused most of Ohio counties to go into at least level two snow emergency and five deaths were linked to this storm (Ohio History Central).

Strong winds can knock down trees, utility poles and .tr cold can cause frostbite or hypothermia and become life an nd the elderly. Freezing temperatures can cause pipes to freeze in freezing and thawing rivers, resulting in flash flooding. Winter storm n also bring heavy accumulations of ice which can down trees, electrical wires, tele one poles and lines, and communication towers. Utilities and communications can be impacted for several days. Heavy snowfall can immobilize a community and create economic impacts related to the cost of snow removal and loss of business. Most deaths related to severe winter weather result from traffic accidents on 49 icy roads, heart attacks while shoveling snow and hypothermia from prolonged exposure to the cold. Vulnerability to the effects of winter storms on buildings is considered to be somewhat dependent on the age of a building because as building codes become more stringent, buildings are capable of supporting heavier loads and as building a arious factors may deteriorate their structural integrity. Vulnerability also depe p he type of construction and the degree to which a structure has been aimed. Commercial buildings, warehouses, and municipal structures with large spa e also susceptible to a collapse under the weight of heavy snow or ice buildup. 6.3.2 Potential Impact of Severe Winter Weather In Franklin County, accumulations of snow and/ ce during winter months are expected and normal. The most common detrimental f snow a or ice are not collapsed structures but traffic accidents and interrup ions wer s and communications services.

Data is only available for housing units. TWrefore, only housing unit structures will be evaluated. It is not nec rily the case that older structures are at greater risk of damage due to heavy snow4Fr ice. There are 12.1 percent of structures standing in Franklin County that were built before 1939 and about a third of the structures in the County are more than 50 years old, and these have withstood many heavy snow and ice storms. Nevertheless, for this review, because the National Trust for Historic Preservation identifies structures greater than 50 years old as being eligible for designation as historic, the assumption is M made that structures built before 1960 are at some risk of at least minor damage due to heavy snow and/or ice. There are 169,283 structures in the County that were built before 1960, thus the percent of structures considered to be particularly vulnerable to damage due to heavy snow or ice is 32.5 percent. Figure 3 shows the number of structures built in Franklin County and illustrates the fact that a large number of structures in the County are more than 50 years old.

This analysis is based on the perception that building codes h come more stringent and that new buildings can withstand the 30 pol�nds per squar oot snow loads expected for Ohio. To estimate the commercial values, the same percentage of structures will be assumed to be built over 50 years ago, which i 2.5%. With the total value of residential and commercial structures being $56 billion IV16 billion, the estimated maximum damage that is expected for a worst case scenario winter storm is $18.2 billion and $5.2 billion, respectively. This estimate does not represent the total cost associated with the winter storm, which will also include damaged utilities and emergency services. Exposure of Future Buildings to Severe Winter Weather All structures and 'tructunrin Franklin County will be exposed to heavy snow and ice. However, Fra-I'mounty adopted in 2009 the International Building Code (IBC) and International Rial Code (IRC) standard. It is assumed buildings built after this date can further wit heavy snow and ice loads. 6.3.4 Estimatli Wotential Loss Methodology According to NCDC, estimated property damage in Franklin County attributable to major heavy snow and/or ice storms over the period 1993 through 2011 is $16,656,000. Past 51 losses provided in NCDC are used to estimate the potential for annual losses due to heavy snow and/or ice. Estimated Potential Dollar Losses Since the total loss over these 18 years is $16,656,000, the avera nnual loss is $16,656,000 / 18 = $925,333. 52 7.1 Tornadoes Update In the previous version of this plan, the Tornado portion had me] Microbursts.

Prior to 2007, the Fujim Scale was commonly used to describe magnitude. This enhanced scale is based on new information about the relationship between wind speed given in miles per hour (mph) and corresponding damages. The EF Scale categorizes tornadoes from EFO to EF5 with ETD being the most commonly occurring type of tornado with the lowest wind speed and least damage. The most damaging and deadliest tomado recorded in Franklin Comely was an F3 tornado on the old Fujim. Table 12 shows the relationship between the Fujim and the Enhanced Fujim Scales. More than 900 tornadoes have struck down in Ohio, with 191 deaths and 4,441 injuries between 1950 and 2010. Of all the counties in Ohio, Franklin Comfy has had the most tornadoes with 29. From these tomadoes, no deaths had been recorded. For all tornadoes hi Ohio about 90% occur while the majority of the population is awake and about 60 happen between 2p.m. and 6p.m. The larges tornado in Franklin Courtly was an F-3 in 1971, which would be an EF -4 with the new scale.

Franklin County has had the highest recorded number of tornado sightings in Ohio, 22 since 1950, with only 2 recorded deaths since 1916 and none since 1950. However, Franklin County has not experienced maximum tornado damage. Historic weather events collected by the National Weather Servic m uary 1993 through December 2008 indicate the most recent tornado touchd in Franklin County occurred within Mudsock near Hilliard on May 11, 2008. F received minor damage and property loss estimates totaled more than 00. tornado event registered F-0 on the Fujita. Appendix V lists previo s urrences of tornadoes in Franklin County; data is from NCDC'which covers t rs 93 through 2011. Many snow storms include some ice; for this analysis, th re presented as both snow and ice occurrences. 7.2.4 Probability of Future Tornadoes JK There were 29 damaging tornadoes reported by the Weather Service National Climatic Data Center for FrankF ounty for the entir -2010 period. Thus the calculated probability of a damagin do in the County iven year is 29/60 = 0.48 or 48 percent. 1 7.3 Vulnerability Assessment —Tornadoes Ir 7.3.1 Overview ownera bi I ity Anything int path of tornado is at ris For tornadoes, aged and dilapidated structure or tures not built to applicabl ing codes are more susceptible to damage. Mobile omes and campgrounds are ecially susceptible to damage due to tornado. Strong winds can rip roofs off of an ilapidated structures and overturn mobile ural areas are ore�bsed tornadoes, but the destructive capability cr�i eases urban areas, as demonstrated in Xenia, Ohio. While the county records of deaths after 1950 is zero (2 deaths in 1916) and a low her of injuries from tornadoes, the potential for severe destruction and death remains. ation increases and further expansion of the outdoor siren warning system will also one to a continued emphasis on public education. 7.3.2 tial lnwct of Tornadoes Vulnerability the effects of a tornado is somewhat dependent upon the age of a structure be use as building codes become more stringent, buildings are more capable of enduring greater wind forces. In a worst case scenario, Franklin County could be hit with an EF -5 tornado that would travel from one side of the county to the other. No matter what the path, if an EF -5 went -M through the County tens of thousands of buildings would be destroyed. Even with the current building codes, most buildings cannot withstand the forces of an EF -5. Apart from the devastation within the path of the tornado, large regions of the county can be expected to be without power. 7.3.3 Identifying Structures Exposure of Existing Buildings to Tornadoes The methodology for identifying structures potentially at riskof damagetid e to tornadoes is the same as the methodology used for identify structu es potenally of damage due to heavy snow or ice. All structures and infrastructure has the pote to be e osed to tNeecof a tornado. Depending upon the severity of a any e ing structures co damaged or destroyed. However, in Franklin Co here e 9,283 structures t were built before 1960. Thus the percentage of exist s co sidered at part ular risk of damage due to tornado or high wind is 32.5 perc To predict the structural cost associated ith a worst case io for a tornado; an analysis will be run with an EF -5 tomad ing on a straight ough the most densely populated and developed area wit nty. This ana sis uses a tornado with a destructive path of three quarters of a mile e while traveling approximately 25 miles across Franklin County from the Southw ide to the Northeast side of the county. To perform this sis a GIS query was onclucted. In T,Able 14, an assessment shows the amount o age that is expectedper e of structu%. It also shows the value of damage that is expected for this worst cases ario. The degrees of damage in the table are from4Destroyed to Affected and the mon ry amage associated with the damage corresponds to the degree of damage. For example a destroyed home was calculated at a it was totally destroyed, where as a home merely affected only as damages. 57 Table 14: Damage Assessment for an EF -5 Tornado through Franklin County Exposure of Future Buildings to Tornadoes Any future structures have the sam tentialfor this hazard does not occur in sped ocation F resistant to the effects of tornado or igh wi building code requirements for bracing d roof des i 01 The Franklin Co is ent data is used support the NCDC data to estimate OOt1 osses fr ecific hazard.

This section h been hanced to include high winds, hail, and microbursts. The 2010 Franklin County Risk Assessment and the NCD site ed to capture the data used in this document. 8.2 Hazard Profile -Severe Summer Weather 8.2.1 Location Severe thunderstorms, lightning and hail can pose a threat to li e an property in any part of Franklin County by creating conditions that disrupt essential services. High winds have destructive impacts to tree power lines and other ities, which ultimately impacts residents. In July 2003, a serie f severe thunders with extraordinarily high winds downed numerous tree thr Franklin Con lting in power outages affecting more than 100,000 usto a period ee to five days. Downed trees also blocked roadways ougho ch had to be cleared quickly to ensure emergency response vehicl ad ac ss. e damage and potential impacts from se ere thundekorms and hig\vinds should be underestimated. A weathe t which appears commonl n Franklin County is the microburst. Microbu is g ly occur within an isolated ut can cause damage similar to that of a tornado. Allikilillilkbd Dama Severe summe s occ out the State of Ohio. All of Franklin County is exposed to the ha associa ith severe summer storms. These storms can contain hail, wind, tornadjser robu and thunder and lighting. k High winds froweather that move in a straight line can cause extensive damage, much linado. High winds are defined as sustained wind speeds of 40 mph or greater la1 hour or more, or winds of 58 mph or greater for any duration. Microbursts lso known as downbursts) are powerful downdrafts associated with thunderston rain showers and particularly hail. Microburst winds can equal that of small tornadoes and the damage looks as if a tornado went through the area. Wind speeds above 120 mph in microbursts are not uncommon. M 8.2.3 Previous Occurrences During the period from January 1950 to March 2010, there were more than 388 weather events involving severe thunderstorms, hail and lightning resulting in property damage estimates totaling over 319 million dollars in Franklin County. The majority of damage resulting from these events is downed trees and power lines. OtV ages include roofs being blown off, semi -tractor trailers being knocked overig ng strikes. Based on the 2010 Risk Assessment, four deaths have occurredndividuals being struck by lightning over a 60 year period. More than 56 people were injured and four people were killed between January 1950 to March 2010 Ault of thunderstorms and high winds. Although damage from severe thunderstorms and lightnik has occurre out Franklin County, the majority of damage reports have come f om the northern h he county. The northwest and northeast quadrants of Fra County are the populous, rapidly growing areas. The conclusion co be dr that as the popul n increases and more development occurs, more dama erty ay occur and ore lives may be at risk from thunderstorms and lightning. t FEMA Region V provides information reLarding the types a uency of disasters in Ohio. Table 14 provided by FEMA V illikogs the Franklin atural Hazards Mitigation Plan's emphasis on floodinVn s in Frank ounty. Table 15: Flooding and Nere Storm County Pr 8.2.4 Probability of Future Severe Summer Weather There were 258 thunderstorm and high wind events reported in Franklin County for a period from 1950-2010. Thus the calculated probability of a damaging tornado in the county in any given year is 258/59 = 4.37 or 437 percent. Thus, the average number of damaging thunderstorms and high wind events for the county is 4.37 storms per year.

Thus, the average number of damaging thunderstorms and high wind events for the county is 4.37 storms per year. So M the probability of the occurrence of a damaging thunderstorm or high wind event in Franklin County in any given year is 100 percent. 8.3 Vulnerability Assessment —Severe Summer Weather 8.3.1 Overview of Vulnerability Not all thunderstorms carry risks to property and lives. They bring needed rain to farmlands and reservoirs. No place in the United States is completely immune to the threats of severe thunderstorms. Thunderstorms can produce several severe weather conditions that are harmful to life and property includ�sh flooding, lightning, hail, high winds and tornadoes. History tells us that Franklin County has always experienced thunderstorms and always will. Storm severity cannot be predicted, but improved ather radar and public warnings may lessen the impacts of these stor allow' sidents to be better prepared. 8.3.2 Potential Impact of Severe Summer Weather The National Weather Service (NW that over 100,000 thmAerstorms occur each year on the U.S. mainland. Ap xi percent are classified as "severe." Thunderstorms can produce deadly, d da ing tornadoes, hailstorms, intense microburst winds, lightning and flash ds. ce 1975, severe thunderstorms were involved in more than 327 Federal disast clarations.ery thunderstorm produces lightning, wh' ills ilad ple each year ban tornadoe .

The most common detrimental effects are ptions in po r upply and communications services due to downed wires and b roadways due downed trees. i As seen in a large portion of Ohio, including Franklin County, Tropical Depression Ike passed through Ohio with devastating force leaving hundreds of thousands without power with thousanr5f trees blown down. In a worst case scenario, a severe summer storm could pass er Franklin County causing large power outages leaving hundreds of thousands without power. Large quantities of trees and large limbs will fall down potentially destroying everything that they fall on to, which will include structures, power lines, and vehicles. Downed trees will also have the potential to obstruct emergency routes delaying emergency response times. The wind forces from a worst case scenario 61 event like this will have the potential to knock over dilapidated buildings and cause exterior damage to a vast number of buildings within the County. 8.3.3 Identifying Structures Exposure of Existing Buildings to Severe Summer Weather I The methodology for identifying structures potentially at xisk of damage due to severe summer storms is the same as the methodology usedfor 'den y structures potentially at risk of damage due to heavy snow or ice. All structures and infrastructure within Frankli unty cou d be exposed to the effects of severe summer storms. Depending upo verity o he storm, any existing structures might be damaged to some extent. in in County, there are 169,283 structures that were built before 1960. Thus er tage f existing buillmgs considered at particular risk of damage due to severe summer storms is 32.5%. t To predict the structural cost associatediLa worst case scenario for a severe summer storm (which could include wind, hail an ); it is assumed th structures older than 50 years will be significantly dalged. is analysis is based he perception that building codes have become more stringent and that new building ill withstand all wind forces expected in Ohio. To estimate the commerci'aNvalues, the same percentage of structures will b to be built over 0 years ago, which is 32.5%. With the total value of residen sal an commercial struct r s being $5t billion and $16 billion, the estimated maximum damage that is expect for worst case scenario wind and hail damage is $18.2 billion and $5.2 billion, respec Exposure of Future Bings to Se*ftVoreather y futur es could be exposed to severe summer storms as this hazard does not occur in specs tions. However, future buildings may be less likely to be damaged by the effects of summer storms as they will meet the most current building code �uirein for br roof design, and electrical grounding. Loss According tc the NCDC, estimated property damage in Franklin County attributable to the four hazards associated with summer storms are thunderstorms, lightning, high winds, and hail account for $188,818,000 in damage. Damage attributable to thunderstorms from 1950 through 2011 is $7,482,000. Damage attributable to lightning from 1993 through 2011 is $25,000. Damage attributable to high winds from 1993 through 2011 is 62 $130,700,000. Damage attributable to hail from 1950 through 2011 is $181,311,000. This data is used to estimate potential annual dollar losses due to severe summer storms. Estimated Potential Dollar Losses Due to severe summer storms combining four hazards that have en historically documented over different periods of time, the potential dollar es4om severe summer storms will be broken down into each specific dollar The total loss for thunderstorms over 61 years is $7,482,000, the average annu is $7,482,000 / 61 = $122,655. The total loss for lightning over 61 years is $25, the a rage annual loss is $25,000 / 18 = $1,388. The total loss for high winds over 1 ears is 130 00,000, the average annual loss is $130,700,000/ 18 = $7,261,11. Them ' rity of highds costs are associated with one event that totaled 98% of total costs. The total loss for hail over 61 years is $181,311,000, the average nual loss is $181,311,000 / 61 = $2,972,311. The majority of the costs asso ith hail damages are contributed to two large hail events that caused excessive damag The total average estimated annual cost to all severe'l weather is $10,357,465. curate depiction of the 63 9.1 Drought Update The drought section for this plan was created for the 2011 plan t hazard had been identified in the previous plan, there was no hazard.

Economic effects in Franklin County would include crop loss. No structural damage due to drought is anticipated in Franklin County. 67 9.3.2 Potential Impact of Drought Negative impacts of drought would be experienced by agricultural interests, and some communities would need to reduce water usage in times of severe drought. Communities reliant on reservoirs built to endure times of drought may endure the impacts of drought better. The major crops in Franklin County are soybeans, corn, and w with totals of 24,455, 17,868, and 2,334 acres, respectively, harvested in 2007.

Due to a rapid multiplication, a town off Lake Michi lost water for three days when a colony of zebra mussels clogged their water -int e. Zebra mussels are easily transported on vessel hulls and multiply fairly rapidly. Any ash tree within the state of Ohio has the potential to bfected by the emerald ash borer. It is not a question of if the emerald ash borer evil ect an ash tree but rather when. The population is increasing and it is only a m tter of Ae till it affects all the ash trees in the state. The emerald ash borer is a beetle t cheA the inner bark and phloem of the ash trees. The feeding of the beetle creat oles that cut the flow of nutrient and water to the rest of the tree. 10.3.2 Potential Impact of Invasive Species � The replacement of all the ash within Ohio parks, streets and on private property is expected to cost betweei s pillion and $29 bi Although zebra mussels have impacte h, Franklin Co has seen minimal impacts of this species. Those that are ected ters facilities that utilize water from the affected water bodies have bee le the introduction of this species. 10.3.3 Exposui identified as potentially 311Wdamage due to invasive species are ones ound in odies of water, like water intake pipes. Therefore, if zebra mussels are known to be in the same water ways as an inoke, regular maintenance can prevent damage to the facility using the intake. There is no current data shown for effects of invasive species on buildings. Even though mvasiv ecies are an ever changing list, at the current time, no invasive species are shown to se damage to any type of existing structures. Exposure o uildings to Invasive Species Damages Future buil gs should have the same vulnerability to invasive species as existing buildings. Currently, there are no buildings that are affected by any invasive species. Therefore, no damage is expected by invasive species. 70 10.3.4 Estimating Potential Loss Methodology The 2010 Risk Assessment estimates that the cost to Ohioans can be as much as $4.2 billion and as little as $1.0 billion for the replacement of the ash trees to other resistant trees. The price will ultimately be dependent on the timeframe d the ounts that municipalities will be able to afford for the replacement of the rees. To obtain an estimated amount for Franklin County, these amounts will b de up over 10 years and the 88 counties.

I k* 11.2 Hazard Profile -Earthquake 11.2.1 Location` An earthquake could affect any part of Franklin County. Franklin CouNiscated on a fault line, nor have any epicenters been located in Fr lin Coulosest significant fault that might contribute to an earth ke in Fr lin County is the New Madrid Fault, located in Missouri. 11.2.2 Extent of Damage Although Ohio is not thought of as an earthquake-proNstaleast 160 earthquakes with epicenters in Ohio have been felt since 1 Most have been fell/nly locally and have caused no damage or injuries. Ie la rg c earthquake in the state occurred in 1937. This event had an estimated magnitude nd caused considerable damage in the town of Anna and in several other wes m Ohi ommunities. Ohio is on the periphery of the New NALd Seismic Zone, an area in Mi�sturi and adjacent states that was the site.40F the 1 arthquake sequence to occur in historical times in the continenta ited States. 980, an earthquake with a magnitude of 5.3 on the Richter Scale an centered in Sh burg, Kentucky, watstrongly felt throughout Ohio and caused minor damage in communities along the Ohio River in southwestern Ohio. In 199 2 magnitude earthquake occurrewestern Pennsylvania and caused some %ind central area. Three regions of the state have been identified as susceptiblmic activity; however neither Franklin County nor its contiguous counties ain these regions. re are two d' ways � scribing the magnitude of an earthquake. One way res peak grou celeration. Peak ground acceleration is the maximum horizontal gr acceleration asured in centimeters per second per second (cm/sec). Peak ground acceleration range from zero for an earthquake that is noticed by very few people to 350, whic would a catastrophic event. A peak ground acceleration of 10 cm/sec2 mean the shaking is equivalent to about 1 percent of the acceleration due to gravity. Gen y, ground acceleration must exceed 15 cm/sec for significant damage to occur. Accolvding to the U.S. Geological Survey (USGS) Earthquake Hazard Program and as shown in Figure 8, peak ground acceleration in Franklin County during an earthquake would measure around 6 cm/sec, as it is located near where the colors in the Figure 8 change from light blue to gray. 72 42"N 40'N 38'N 84'W 82`W 80V DetroR � a� 0 r 0 m oa iY COLUMBUS ANAP US CHARLESTO FR NKFO 42'N 40'N 38°N 84'W 82'W 80'W Peak Acceleration (%g) with 2% Probability of Exceedance in 50 Years site: NEHRP B -C boundary National Seismic Hazard Mapping Project (2908) Figur USGS Seismic and Map —Ohio of measuring the i an earthquake is the Modified Mercalli enst easures on this scale range from 1, an earthquake that is not generally noticeable, to 12, an earthquake that auses complete destruction.

USGS data identify that there has been zero earthquakes with the fticenter within Franklin County. USGS data shows only 43 earthquakes impactin o ween 1776 and 2007 with a magnitude of at least 3.5. 11.2.4 Probability of Future Damaging Earthquakes Given that USGS identifies Franklin County as havin a 2% chance over 51! years to have an earthquake with a ground acceleration of 6 c �. It can be concluded that to get ground acceleration large enough to cause sig ant damage, 15 cm/sec, the *any would be less than 2% over 50 years. The estimated probability of a damaging earthqua Fra lin County given year is estimated at less than 1 percent per year. is based on the analysis by USGS estimating a 2% chance o 0 year, which is a chance of occurrence in one year. As part of the 2011 Franklin Count Natural Hazards Mitigatio an Update it was decided that utilizing HAZUS would benefit Franklin County and t e other jurisdictions involved to determine loss estimates for this regional hazard. These loss estimates are utilized primaril and stimulate efforts to reduce risii� from natural hazards and to prepare for emergenc esponse and recovery. Since an earthquake is a wide spread hazard HAZUS was utilized for this particular azard in order to generate more accurate loss estimations for the planning effort. 111610 11.3 Vulnerability Assessment —90&qu 11.3.1 OvAl4ew of Vulne All structures and infrastructu anklin County are equally at risk of experiencing an Shq,ake uHoweven a mi earthquake of the magnitude typically experienced in nostructural dage is anticipated. In other cases, damages are expected to be nd examplescipated damages are broken dishes and windows and toppled 11.3.2 Pof�act of Earthquake Based on thrhistory of earthquakes in Ohio, no structural damages are anticipated in Franklin County. However, for earthquakes, the available history covers a period of just over 200 years, which is relatively short period of time for an examination of earthquakes. Large earthquakes may only affect a location every several centuries or millennia. 74 A very large earthquake affecting Franklin County might cause structural damage in dilapidated structures or structures that do not meet current building codes. Roads and bridges might be damaged and trees and power lines might fall. Thus the impact of an earthquake might range from negligible to minor damage. Based on over 200 years of experience in Franklin County, there will most likely be no damage or very slight damage. If in the worst case scenario amagnitud 5.4 eAVquake, the strongest earthquake in Ohio's history, were to have an epicenter ' he center of Franklin County, then moderate damage would be expected. HAZUS estimates that there are 386,000 buildings in the region which have an aggregate total replacement value of 91,875 million. For a 5.4 magnitude earthquake, HAZUS estimates that about 54,130 buildings will be at least moderately damaged. This is 14.0% of the total number of buildings in the scenario. There are an estimated 10,219 buildings that will be completely destroyed by having over 50% damage to the structure. Table 17, shows an estimated total damage for each occupancype wFranklin ranklin County that k can be expected.

Table 17 shows that Franklin County can expect the greatest losses from flooding. Annualized anticipated losses due o flooding are more than all other losses combined. The next biggest estimated a dollar loss is severe summer weather. The estimated annual cost of severe sum weather is due to two significant hail events. Annualized anticipated losses due rnado are comparable to the anticipated losses due to severe winter weather, but ave a lesser annual probability of occurring. Even though the potential for a 100 -ye d to occur is only 1%, the risk of billions of dollars in damage for that event ma a very devastating hazar Thus, the majority of actions proposed in this mitigaf lan addr ss potential dama to flooding.

This makes it extremely dif is t when asse the val*Ao each facility. For each hazard, aside from flooding and tornadoes, all c cilities are assumed to withstand normal forces and events based on the hazards a mg Franklin County. This is assumed because these facilities are typically designed meet building code and they are typically maintained by the personnel occupying the building. Therefore, no damages are assutped for these types of facilities. In the as of flooding, HAZUS has assigned a value of damage to only the structures that wiles M cted. This value indicates that the critical facilities will only be slightly impaired d not completely damaged. To evaluate critical facilities in�fhe worst case scenario for a tornado, each )st destruction was evaluated on an individual basis. This is the structures wre evaluated on.

This section summarizes the process used to develop the Actio an for the four natural azards identified in the mitigation plan including flood i evere thunderstorms and liing, tornadoes and severe winter weather. The mission of the Franklin County Natural HaitigVIMKlan is to provoF a comprehensive view of natural hazards in Franklin ty and make recommendations designed to protect citizens, essential facilities, infrastr cture and private property from natural hazards. This can be ac eved by incorporating these ideas into existing and future land use planning docume identi ing at -risk infrasNoture�and increasing public education about natural hazard The Core Group examined existing and repetitivifPMft and the mitigation oals were identified based on thf a specific area umbrella over several pro goal. ingsKng in Franklin County .

This section focuses on the types of actions communities have specifically identified to mitigate risks and potential losses. The following mitigation actions are discussed in four primary areas: preventative measures, property protection, resource protection and structural projects. 13.3.1 Preventative Measures Preventative measures are those) measures put in place to protect new and future development from potential hazards.

Various local planning documents are referenced in the flooding chapter of this plan. EX Zoning ordinances or resolutions provided criteria for how land should be used within a zoning district. 13.3.5 Property Protection Property protection measures are used to modify buildings or property ect to damage to lessen its impact. Flood proofing a structure is a form of propert e . A flood proofed structure is designed to allow the structure to flood with imal damage, so the structure is usable relatively quick after the event. 13.3.6 Physical Barriers A number of alternatives exist to protect property in the'ects of floodi rriers can be created to keep a flood hazard away. Th anklinton Floodwall is an e of a flood barrier. Completed in 2004, this st s design to re -direct the 8 water away from improved properties in low-lyin Re n, building elev on and demolition are other alternatives available to re isk s ctures from h and areas. 13.3.7 Retrofitting Retrofitting involves modifying a pro y or site to minimize or p nt damage. Flood retrofitting measures can include both ry and wet flood proofing. n dry flood proofing, walls are coated with waterproofing compounds and an�Ropenings are closed. Wet flood proofing ^the umption tha ooding will our and everything that could be damaemoved or elevated above the flood level. Structural componevel are replaced i� th materials that are not subject to water damage.L; rce Protection RTesource`PN! ection involves preserving natural areas such as fields, floodplains and wetlands in a natural state. This c4pter covers the resource protection programs and standards that can help mitigate the impact of natural hazards, while improving the Lrall environment. Many of these issues have been touched upon in the hazard specific Wetlands arrally found in floodplains and depression areas of a watershed. Wetlands se as a depository for floodwaters, which reduces the flow of water downstream. They also serve as a natural filter, which helps to improve water quality, and provide habitat for fish, wildlife and plants. Wetlands that are determined to be part of the waters of the United States are regulated by the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency 81 under Section 404 of the Clean Water Act. Before a "404" permit is issued, the plans are reviewed by several agencies, including the Corps and the U.S. Fish and Wildlife Service. Each of these agencies must sign off on individual permits. There are also nationwide permits that allow small projects that meet certain criteria to proceed without individual permits. Wetlands not included in the Corps' jurisdiction or that are addressed by a nationwide permit may be regulated/etland uthoritiE. If a permit is issued by the Corps or the county, the the development is typically required to be mitigated. Wetland mitigation careation, restoration, enhancement or preservation of wetlands elsewhere �mitigation is often accomplished within the development site, however, /litigation is allowed off-site and sometimes in another watershed. When a wetland is mitigated at another site there are drawbacks to consider. First, it takes many years for a new wggtland to approach the same quality as an established one. Second, a nwetland in Odifferent location will not necessarily have the same flood damage reduction benefts as t e orieal one did. 40 13.3.10 Erosion and Sedimentation Control Farmland,, water rur waterway. velocity o osed soil.

A key component of these efforts is to use appropriate native 82 plantings along the banks that resist erosion. This may involve retrofitting the shoreline with willow cuttings, wetland plants and rolls of landscape material covered with a natural fabric that decomposes after the banks are stabilized with plant roots. Restoring the right vegetation to a stream helps reduce the amount of sediment entering the water, can reduce flood damage by slowing the velocity of water a n reduce long term maintenance costs. 13.3.12 Structural Projects Structural projects are usually funded by public agen ies� cons to protect people and infrastructure from damage due to natura s. loodwate agement is the primary focus of structural projects.

"Debris s to wide range of blockage materials that may include tree limbs and branches t ulate naturally, or large items of trash or lawn waste accidentally or I ped into channels, drainage swales or detention basins. Maintenance activities do of alter the shape of the channel or pond, but they do affect how well the drainage system can do its job. Sometimes there is a fine line that separates debris that should be removed from natural materials that helps form habitat. Therefore, written procedures that are consistent with state laws and environmental concerns are usually needed. 83 For each goal, the Core Group Committee used the results of the risk assessment to identify action items that might move the County toward achieving its long-term goals. Goals and action items were modified slightly based on the results o updated Risk Assessment. 14.1 Mitigation Action Items Update At the June, 2011 meeting, the Core Group Committee an*articipaJing jurisdictions reviewed mitigation objectives. Some objectives were idenillQe3las having been achieved in Franklin County since the initial version olihis plan was prepared. Completed objectives for the County remain and are brie scribed i discussions below w mitigation accomplishments since the initial VPdevelope 14.2 Mitigation Action Items Prioritization Proc 14.2.1 Prioritization Methodology IV R The Mitigation Core Group began the prioritization process by examining the action items from the original version of th�plan and taking a risk based approach. The risk based approach agreed upon by the committee was to utilize the hazard ranking from the Risk Assessment fo Franklin County and gr the ac*n items based on the hazard they address. FA ample, Short-term action item #1 addvZes flooding and flooding is the #1 bazar ranklin County, so that project is ranked as a #1 priority project. In the Risk Asse for Franklin County the hazaYds were carefully ranked according to a pre -deter ine thodology with the assistance CO subject matter experts, so the Core Group adopted that methodology to ensure consistency across all plans. This process geaiwwliLresults that the Mitigation CorOrifoup and Franklin County Emergency Homeland Security felt represented the true intent of the prioritization Action Ite JK an was desig to serve as a county -wide strategic plan which jurisdictions can ide local ation efforts. Included in this plan are short-term action items, tion It nd jurisdiction based action items. The core group vKrked to define the short-term and long-term action items. The short- term action Pms were considered the higher priority items in that they addressed a specific proglem, they could be completed in less than five years and funding could be reasonably expected. The long-term action items are those items considered to be continuous or take more than five years. Funding requirements range from very little (planning issues) to very expensive (replacing aging infrastructure). 84 14.2.3 Natural Hazards Mitigation Plan Action Items This mitigation plan identifies short and long-term action items developed through core group activities, research and data collection. These activities may require federal and state grant funding, or be implemented at the local level through partnerships and cooperation. Each Action Item is separated into four components t include the following: • Ideas for Implementation: Actions that can be takeND als of the action item • Coordinating Organization: Organizations willing tresources, identify funding sources (if necessary) and monitor activityion • Timeline: An estimate of the amount of time needed to implement the action • Plan Goals Addressed: This identifies the specific goal the action item ad4resses • Benefit Cost Review: Provides a comprehensive review of monetary and non - monetary costs and benefits associated with each action. A*Benefit Cost Review for all the short-term and long-term action items was conducted. In addition to the action items dev d by the core group, .urisdictions were asked to update and create action items pecifically to the icti ns. They were given copies of the goals and action developed by the core n order to guide their efforts. Based on the goals identi d, there are en short-te and five long-term action items developed by the Core up Com le nal local jurisdiction Action Items are lis the section, Juri dictional Mitigions. Since the Core Group Action Items were devel ped in the previous plan, some have been addressed�nd are as follows: • Short-term Action Item 41: This new ction item involves the purchasing of property along Whims Ditch tor repeat property damage due to flooding. Short-term Action Item 42: This ew action item encourages more storm water retention to reduce the amount of flooding and bank erosion. • Short-term Action Item 43: The purchase of new sirens in halfway complete to cover the remaining parts of the County. Short-term on Item 46: This new action item is to develop a system to better help emergen esponders evacuate the population with transportation needs. ng -term Action Item 41: MORPC was added as an advocate to the plan. • Long-term Action Item 42: MORPC was added as a coordinating organization. • Long-term Action Item 45: FEMA kits were added to awareness efforts. • Long-term Action Item 46: The number of repetitive loss properties was updated. Since the previous Plan a few of the Core Group Action Items have been completed. The description of completed action items can be found in Appendix VI. Here is a list of the completed action items: 85 • Completed Action Item 41: Flooding in the City of Whitehall has been alleviated by the removal of debris from nearby ditches and streams. • Completed Action Item 42: The Blacklick logjam has been removed. • Completed Action Item 43: The Reverse 911 System has been purchased in cooperation with the Ohio State University and distributed.

The plan maintenance process includes #hedule for monitoring and evaluating the plan and producing a plan revision every five years. Public meetings and participation will be integrated into the plan maintenance process. The FCEM&HS will continue to work with regional planning representatives local governments and developers to incorporate mitigation strategies o current and future p nning mechanisms. 16.2 Monitoring Mitigation Actions 16.2.1 Plan Adoption The plan will be adopted by all jurisdicti s choosing to partilipate. A sample resolution is included in Appendix I. Once all j tions adopt the updated plan, their signed resolutions will be found in Appen x effort will be made to secure the participation of all jurisdictions in the county. Ian has been submitted to the State Hazard Mitigation Officer at the Ohi me anagement Agency and approved, the plan ��adopted by each ju diction. hio EMA will submit the plan to the Federal Emergency Management Agency EMA) for review. Upon acceptance by FEMA, Franklin County willeligibility for Hazard Mitigation Grant Program funds. 16.2.2 Coordinating Body 777Rklin County Hazard Mitigation Core Group will be responsible for monitoring of plan and undertaking the formal review process. FCEM&HS has formed a Hazard igation Core Group that cons' of members from local agencies, organizations and lens. The Core Group include the following: WAppointed Officials • Fire Officials • Emergencynagement • Natio na ather Service • Geogra is Information System (GIS) • Mid -Ohio Regional Planning Committee (MORPC) • Building and Zoning Officials • Service Departments • Utilities Officials • Insurance Industry 139 16.2.3 Monitoring Mitigation Projects The Franklin County Mitigation Officer will monitor the progress made on the implementation of the identified action items. Jurisdictions will be responsible for updating FCEM&HS on mitigation actions taken. By monitoring mitigation actions, when the plan is next updated, information about the status of proposed mitigation actions will be readily available. The updated plan will include a section explaining if previously proposed mitigation actions have been implemented, completed, or deferred. The updated plan will identify actions that are no longer appropriate for the community and should be deleted. The updated plan will identify obstacles to implementation that caused proposed actions to be deferred and will recommend strategies for overcoming those obstacles. The Core Group will not only monitor the implementation of mitigation actions proposed in this plan, but will also monitor actions of participating jurisdictions and surrounding communities that may affect the ability of Franklin County to withstand the effects of natural hazards or to recover from a disaster in the future. The method for gathering information about actions beyond those proposed in this plan will be informal; as active members of the Franklin County community, Core Group members will bring their own knowledge of the area to monitoring meetings to provide information about actions of participating jurisdictions as well as of nearby communities. 16.2.4 Implementation through Existing Programs, Communities & Organizations Planning is conducted at the municipal level for cities and villages in Franklin County. The Franklin County Economic Development and Planning Department provides planning services for the unincorporated areas in Franklin County. The Mid -Ohio Regional Planning Commission (MORPC) provides planning, programming, and brokerage services for housing, transportation, water, land use, zoning, environmental, and technology issues within Central Ohio. The All Natural Hazards Mitigation Plan includes recommendations that can be accomplished by including mitigation activities into current and future regional planning initiatives. 16.3 Evaluating the Plan 16.3.1 Annual Review Process The Franklin County Natural Hazards Mitigation Plan will be evaluated on an annual basis to determine the effectiveness of programs, and to reflect changes in land development or programs that may affect mitigation priorities. FCEM&HS, with consultation and collaboration from the Core Group, maintains overall responsibility for monitoring and evaluating the progress of the mitigation strategies in the Plan. All jurisdictions will be encouraged to attend a yearly plan update meeting. These meetings will track project progress and discuss any new projects that need to be added. This will provide an opportunity for jurisdictions to discuss any current or new problems and prioritize future funding. They can also share their successes. 140 The committee will review the goals and action items to determine their relevance to changing situations in the county, as well as changes in State or Federal policy, and to ensure they are addressing current and expected conditions. The coordinating organizations responsible for action items will present the status of their action item, the implementation processes and the difficulties encountered, at which time strategies may need to be revised. 16.4 Updating the Plan This plan must be updated within 5 years and again adopted by the County and participating jurisdictions in order to maintain compliance with the regulations stated in 44 CFR Part 201.6 and ensure eligibility for applying for and receiving certain Federal mitigation grant funds. Monitoring and evaluation will identify necessary modifications to the plan including changes in mitigation strategies and actions that should be incorporated in the next update. The Franklin County Mitigation Officer will initiate the process of updating the plan in sufficient time to meet State and Federal deadlines. 16.5 Continued Public Involvement The public will continue to have the opportunity to provide feedback about the Plan. Copies of the plan will be available through Ohio EMA and the FCEM&HS websites. The Franklin County Mitigation Officer will provide access to of the plan to key Franklin County offices. The adopted plan will be posted on the FCEM&HS and OEMA website so that the public has electronic access to the plan. The Web site will include contact information for anyone to provide comment so that residents, business owners, and others who read the plan will be able to provide a comment about the plan or about the mitigation strategies. The Mitigation Planning Officer will maintain these comments and will provide them to the Mitigation Core Group for consideration during the update process The Franklin County Mitigation Officer will post notices of mitigation plan update meetings using the usual methods for posting meeting announcements in the County to invite the public to participate. In addition to posting announcements on the FCEM&HS website, social media will also be used to announce the opportunity to participate. The Franklin County Mitigation Officer will document the number of people who participate in the annual meetings and the results of the meeting for inclusion in the plan during the process. In this way, the public will have an opportunity to become involved in the planning process and to influence mitigation planning decisions. 141 • Alum Creek Lake, Dam Safety Emergency Action Plan, U.S. Army Corps of Engineers • American Association of States Climatologists.

The area boundaries are Mound Street on the south, Broad Street on the north, Beechwood Avenue on the east and Maplewood Avenue on the west. Two creeks, Turkey Run and Mason Run, flow through the area which is a flat plain. The area contains single-family homes and two mobile home parks. Heavy rains totaling two inches or more cause the creeks to overflow, resulting in flooding four to five times per year. The problem is compounded by debris collecting on a culvert grate. The manufactured home parks have been evacuated several times. Other problems include flooded railroad underpasses and flooding at police/911 headquarters. Action Item: Develop a comprehensive plan for addressing habitual flooding problems in the City of Whitehall. IDEAS FOR IMPLEMENTATION: • Forma group of stakeholders to determine the extent and cause of the problem. • Formalize procedures for early notification of incoming rainfall from the Emergency Management Agency to the Whitehall Fire Department in order to have time to remove any debris from the culvert drain. • Evaluate potential solutions for technical feasibility, costs/benefit and environmental impact. • Research and secure funding for potential solutions. COORDINATING ORGANIZATION(S): • Franklin County Emergency Management & Homeland Security (FCEM&HS) • Whitehall Fire Department • City of Whitehall TIMELINE: Completed: The City of Whitehall Mitigation Plan is in Attachment #3 to this Plan. PLAN GOALS ADDRESSED: • Manage Debris Along Streams and Waterways • Minimize Damage to Public and Private Property 177 COMPLETED SHORT-TERM ACTION ITEM 42 PROBLEM: Debris has accumulated in Blacklick Creek resulting in restriction of flow, increase backwater levels upstream, and bank erosion near the blockage. The debris is mostly woody material but also contains trash and litter. The area of blockage is located in the Village of Groveport, between Hamilton Road and Ebright Road, just south of U.S. Route 33. The blockage of Blacklick Creek is a potential threat to private property, public property and road rights-of-way. During times of heavy rain and/or snowmelt, backwater threatens development upstream of the blockage and the bridge carrying U.S. Route 33 over the creek The area north of U.S. Route 33 is an area of considerable new and continuing development in the City of Columbus. Action Item: Identify resources and strategies to remove the Blacklick log jam. IDEAS FOR IMPLEMENTATION: • Conduct a study to identify the extent of the problem, the necessary permit requirements and explore potential solutions. • Evaluate potential solutions for technical feasibility, costs/benefit and environmental impacts. • Research and secure funding for potential solutions COORDINATING ORGANIZATION(S): • Village ofGroveport • Franklin County Soil and Water District • Franklin County Emergency Management & Homeland Security (FCEM&HS) TIMELINE: Complete: The Blacklick log jam has been removed. PLAN GOALS ADDRESSED: • Minimize Damage to Public and Private Property • Manage Debris Along Streams and Waterways 178 COMPLETED SHORT-TERM ACTION ITEM 43 PROBLEM: Technology is available that can automatically call people via their phone lines to alert them to a weather emergency. The system, called Reverse 911, has the same capabilities as the 911 system. Action Item: Establish Reverse 911 capabilities in Franklin County. IDEAS FOR IMPLEMENTATION: Research, secure funding and purchase Reverse 911 system to supplement current warning capabilities. COORDINATING ORGANIZATION: • Franklin County Emergency Management & Homeland Security (FCEM&HS) TIMELINE: Complete: The Reverse 911 System has been purchased in cooperation with the Ohio State University and distributed. PLAN GOALS ADDRESSED: • Minimize Loss of Life from Severe Weather Hazards 179 COMPLETED SHORT-TERM ACTION ITEM 44 PROBLEM: NOAA weather alert radios activate upon a severe weather watch or warning and are beneficial in providing early warning, especially in schools and office buildings. Many schools, offices and critical care facilities do not currently have NOAA weather alert radios on site. Action Item: Purchase NOAA weather alert radios for every hospital, parks and recreation center, public utility facility, large -population venue, private/public school and government building accessed by the public in Franklin County. IDEAS FOR IMPLEMENTATION: • Research, secure funding and purchase NOAA weather alert radios to supplement current warning capabilities. COORDINATING ORGANIZATION(S): • National Weather Service • Emergency Management Agency for Franklin County TIMELINE: Complete: FCEM&HS has a complete list of where the radios were distributed to. PLAN GOALS ADDRESSED: • Minimize Loss of Life from Severe Weather Hazards 180
