Purposefully, our emergency management forefathers put the word mitigation first as a “means” to prevent or minimize the effects of disasters. Mitigation is commonly defined as sustained actions taken to reduce or eliminate long-term risk to people and property from hazards and their effects. Hazard mitigation focuses attention and resources on community policies and actions that will produce successive benefits over time. A mitigation plan states the aspirations and specific courses of action that a community intends to follow to reduce vulnerability and exposure to future hazard events. These plans are formulated through a systematic process centered on the participation of citizens, businesses, public officials, and other community stakeholders. Mitigation forms, or should form, the very foundation of every emergency management agency. To reduce, minimize, or eliminate hazards in their communities, emergency management agencies adopt and implement mitigation practices. The Federal DMA 2000 sets the benchmark and outlines the criteria for communities with the vision to implement hazard mitigation practices in their communities. Walton County and its municipalities realize the benefits achieved by the development and implementation of mitigation plans and strategies in their community. Walton County’s elected officials, public safety organizations, planners, and many others have proven that by working together towards the development and implementation of this plan, they can reduce the loss of life and property in their communities. The jurisdictions covered by this plan include the following: Walton County City of Monroe City of Loganville City of Social Circle Town of Between Town of Good Hope Town of Jersey Town of Walnut Grove ---PAGE BREAK--- 12 I Page Walton County Hazard Mitigation Plan Update 2020 Table of Contents Resolution – Walton County 3 Resolution – Walton County Municipalities 4 Preface 11 CHAPTER ONE - INTRODUCTION 15 Summary Of Updates For Chapter One 16 Introduction 17 Authority 18 Funding 19 Scope 20 Purpose 21 Consistency with Federal and State Mitigation Policies 22 Plan Review 24 Hazard Mitigation Plan Update Committee 26 Public Participation 35 Documentation of Public Meeting Notice 37 Multi-jurisdictional Considerations 38 Incorporation of Existing Plans, Studies, and Resources 39 CHAPTER TWO – WALTON COUNTY PROFILE 41 Summary of Updates for Chapter Two 42 Past Hazards 43 History 44 Past Events 46 Demographics 49 Economy 50 Government 51 Transportation 52 Climate 53 Utilities 54 NFIP Compliance 54 Municipal Information 55 CHAPTER THREE – HAZARD PROFILES 66 Summary of Updates for Chapter Three 67 Risk Assessment 69 ---PAGE BREAK--- 13 I Page Walton County Hazard Mitigation Plan Update 2020 CHAPTER THREE – HAZARD PROFILES (CONTINUED) Natural Hazards 70 Thunderstorm 70 Winter Storm 81 Flooding 87 Tornado 101 Drought 108 Wildfire 114 Earthquake 131 Tropical Cyclone 136 Extreme Temperatures 143 Technological Hazards 147 Hazardous Materials Incident 147 Dam Failure 149 Transportation Incident 152 Terrorism 154 Infrastructure Failure 156 Emerging Infectious Disease 157 CHAPTER FOUR – HAZARD MITIGATION STRATEGIES 161 Summary of Updates to Chapter Four 162 Goals and Objectives 163 Identification and Analysis of Mitigation Techniques 165 Mitigation Strategies 167 Natural Hazards 167 Technological Hazards 185 Completed Mitigation Strategies 188 Deleted Mitigation Strategies 188 CHAPTER FIVE – PLAN IMPLEMENTATION AND MAINTENANCE 189 Summary of Updates to Chapter Five 190 Maintenance 191 Plan Distribution 193 Implementation 194 Evaluation 197 Peer Review 198 Plan Update 199 Conclusion 200 ---PAGE BREAK--- 14 I Page Walton County Hazard Mitigation Plan Update 2020 APPENDICIES Appendix A – Walton County Dams Information 201 Appendix B – Hazard Mitigation Plan Update Committee Sign-In Sheets 202 Appendix C – Walton County Critical Facilities Information 220 Appendix D – Natural Hazard Data Tables 223 Appendix E – Walton County Worksheet 3As 238 Appendix F – Documentation of Peer Review 262 Appendix G – Walton County HAZUS Report 268 Appendix H – Documentation of Municipal Participation 302 ---PAGE BREAK--- 15 I Page Walton County Hazard Mitigation Plan Update 2020 Chapter One - Introduction ---PAGE BREAK--- 16 I Page Walton County Hazard Mitigation Plan Update 2020 Summary of Updates for Chapter One The following table provides a description of each section of this chapter and a summary of the changes that have been made to the Walton County Hazard Mitigation Plan 2016. Chapter 1 Section Updates Introduction • Identification of Mitigation Goals Authority • Verbiage updated Funding • Verbiage updated Scope • Verbiage updated Purpose • Verbiage updated Consistency with Federal Guidelines • Verbiage updated Plan Review • Verbiage updated • Updated mitigation meeting dates for 2019-2020 planning process Hazard Mitigation Plan Update Committee • Updated committee list to match the 2019-2020 planning participants • Updated to meet Federal guidelines Public Participation • Updated to match the 2019-2020 planning process Multi-Jurisdictional Considerations • Updated with requirement descriptions Incorporation of Existing Plans, Studies, and Resources • Updated with new plan, study, and resource incorporations ---PAGE BREAK--- 17 I Page Walton County Hazard Mitigation Plan Update 2020 Introduction The Walton County Hazard Mitigation Plan Update is the first phase of a multi- hazard mitigation strategy for the entire community. This Plan encourages cooperation among various organizations and crosses political sub-divisions. As written, this Plan fulfills the requirements of the Federal DMA 2000. DMA 2000 provides federal assistance to state and local emergency management agencies and other disaster response organizations to reduce damage from disasters. The Act is administered by GEMA and FEMA. It is important that state and local government, public-private partnerships, and community citizens can see the results of these mitigation efforts; therefore, the goals and strategies need to be achievable. Walton County’s Hazard Mitigation Plan Update Committee adopted the following goals during plan development: GOAL 1 Maximize the use of all resources by promoting intergovernmental coordination and partnerships in the public and private sectors GOAL 2 Harden communities against the impacts of disasters through the development of new mitigation strategies and strict enforcement of current regulations that have proven effective GOAL 3 Reduce and, where possible, eliminate repetitive damage, loss of life and property from disasters GOAL 4 Bring greater awareness throughout the community about potential hazards and the need for community preparedness This plan complies with all requirements and scope of work as described in Walton County’s Hazard Mitigation Grant application. ---PAGE BREAK--- 18 I Page Walton County Hazard Mitigation Plan Update 2020 Authority In the past, federal legislation has provided funding for disaster relief, recovery, and some hazard mitigation planning. The DMA 2000 is the latest legislation to improve the planning aspect of that process; it reinforces the importance of mitigation planning and emphasizes planning for disasters before they occur. The DMA 2000 establishes a pre-disaster hazard mitigation program and designates new requirements for the national post-disaster Hazard Mitigation Grant Program (HMGP). Section 322 identifies the new requirements for planning activities and increases the amount of HMGP funds available to states that have developed a comprehensive mitigation plan prior to the disaster. State and local communities must have an approved mitigation plan in place prior to receiving post-disaster HMGP funds. Local mitigation plans must demonstrate that their proposed mitigation measures are based on a sound planning process that accounts for the risk to and the capabilities of the individual communities. To implement the new DMA 2000 requirements, FEMA prepared an Interim Final Rule, published in the Federal Register on February 26, 2002 at 44 CFR Parts 201 and 206, which establishes planning and funding criteria for states and local communities. Developed in accordance with current state and federal rules and regulations governing local hazard mitigation plans, Walton County’s Updated Hazard Mitigation Plan will be brought forth to each participating jurisdiction in Walton County to be formally adopted. The Plan shall be routinely monitored and revised to maintain compliance with the following provisions, rules, and legislation: Section 322, Mitigation Planning, of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, as enacted by Section 104 of the Disaster Mitigation Act of 2000 (P.L. 106-390); and FEMA's Interim Final Rule published in the Federal Register on February 26, 2002, at 44 CFR Part 201. ---PAGE BREAK--- 19 I Page Walton County Hazard Mitigation Plan Update 2020 Funding Walton County was awarded a $44,000 Hazard Mitigation Planning Grant by FEMA through GEMA for the update of Walton County’s 2015 Hazard Mitigation Plan. FEMA contributed 75% and GEMA contributed 10% of the total cost of the Plan Update. The Hazard Mitigation Planning Grant required a 15% match by Walton County. This match was fulfilled entirely (100%) by In-Kind contributions – time spent by county and municipal employees, local stakeholders, representatives from organizations, and citizen volunteers updating the Plan was provided instead of cash from the County’s budget. ---PAGE BREAK--- 20 I Page Walton County Hazard Mitigation Plan Update 2020 Scope The scope of the Walton County Hazard Mitigation Plan Update encompasses all areas of Walton County, including municipalities. The Plan identifies all natural and technological hazards that could threaten life and property in Walton County. The scope of this Plan includes both short and long-term mitigation strategies with implementation and possible sources of project funding. The Hazard Mitigation Plan Update is organized to incorporate the requirements of Interim Final Rule 44 CFR 201.4. Chapter One includes an overview of the Hazard Mitigation Plan Update, the overall goals of the plan, and details of the planning process as required by Interim Final Rule 44 CFR 201.4(c)(1). Chapter Two of the Plan details the Walton County profile, including the demographics, municipalities, and history of the county. Chapter Three identifies the risk assessment process, past natural hazard events with associated losses, and current natural hazard risks. Potential losses are also analyzed as required by Interim Final Rule 44 CFFR 201.4(c)(2). Additionally, Chapter Three identifies and analyzes potential technological hazards faced by Walton County. Chapter Four identifies Walton County’s hazard mitigation goals and objectives, mitigation strategies and actions, and sources of potential funding for mitigation projects as required by Interim Final Rule 44 CFR 201.4(c)(3). Chapter Five identifies the maintenance and implementation strategies for the Plan. The process for evaluation of the Hazard Mitigation Plan implementation progress is also detailed as required by Interim Final Rule 44 CFR 201.4(c)(4) and ---PAGE BREAK--- 21 I Page Walton County Hazard Mitigation Plan Update 2020 Purpose The purpose of the Walton County Hazard Mitigation Plan Update is to: • Protect life, promote safety and preserve property by reducing the potential for future damages and economic losses that result from natural and technological hazards; • Make communities in Walton County safer places to live, work, and play; • Qualify for grant funding in both the pre-disaster and post-disaster environments; • Speed the recovery and redevelopment process following future disaster events; • Demonstrate a firm local commitment to hazard mitigation principles; and • Comply with state and federal legislative requirements for local multi- jurisdictional hazard mitigation plans. ---PAGE BREAK--- 22 I Page Walton County Hazard Mitigation Plan Update 2020 Consistency with Federal and State Mitigation Policies The Plan is intended to enhance and complement state and federal recommendations for the mitigation of natural and technological hazards in the following ways: • Substantially reduce the risk of life, injuries and hardship from the destruction of natural and technological disasters on an ongoing basis; • Create greater public awareness about the need for individual preparedness and about the need to build safer, more disaster resistant communities; • Develop strategies for long-term community sustainability during community disasters; and, • Develop governmental and business continuity plans that will continue essential private sector and governmental activities during disasters. FEMA publishes several guidance documents for local governments on mitigating natural disasters. The updated Walton County Hazard Mitigation Plan recognizes, adopts, incorporates, and endorses the following principles: • Develop a strategic mitigation plan for Walton County; • Enforce current building codes; • Develop incentives to promote mitigation; • Incorporate mitigation of natural hazards into land use plans; • Promote awareness of mitigation opportunities and programs throughout our community on a continual basis; and, • Identify potential funding sources for mitigation projects. The private sector is often an overlooked segment of the community during disasters. It is vital that this sector of a community is included in mitigation efforts that are consistent with state and federal recommendations, such as the following: • Develop mitigation incentives with insurance agencies and lending institutions; ---PAGE BREAK--- 23 I Page Walton County Hazard Mitigation Plan Update 2020 • Encourage the creation of a business continuity plan for the continuance of commerce during and following a disaster; and, • Partner with local businesses to educate customers about potential hazards in the community and possible mitigation ideas. Individual citizens must be made aware of the hazards they may encounter. Additionally, they must be educated on how to protect themselves from the hazards they face. They must be shown that mitigation is an important part of reducing loss of life and property in their community. Their support is critical to the success of any mitigation effort. The updated Walton County Hazard Mitigation Plan supports the following FEMA recommendations regarding individual citizens: • Become educated on the hazards that may impact your community; • Become part of the process by supporting and encouraging mitigation programs that reduce vulnerability to disasters; and, • An individual’s responsibility is to safeguard his/her family, as well as themselves, prior to a disaster event. ---PAGE BREAK--- 24 I Page Walton County Hazard Mitigation Plan Update 2020 Plan Review Requirement §201.6(c)(1) The contractor, Lux Mitigation and Planning, had the primary responsibility for collecting updated information and presenting pertinent data to the Plan Update Committee. An online, Dropbox folder was created for Walton County’s Plan Update. The approved 2016 Hazard Mitigation Plan was uploaded to the Dropbox folder, and the link to the folder was emailed to all members of the Hazard Mitigation Plan Update Committee. Each chapter of the 2016 Plan was reviewed. Hazard vulnerability and risk assessment data was updated, as was critical infrastructure information. Special attention and consideration were given to the review and edit of mitigation strategies listed in the 2016 Plan. The Plan Update Committee examined each strategy and determined whether the strategy had been completed, needed to be modified, was in progress, or no longer applied. The Committee was highly encouraged to create new mitigation strategies to meet the current needs of the county and municipalities. Mitigation strategies from other Georgia counties were reviewed to help with the creation of new strategies. When the Committee agreed a new mitigation action would be beneficial, it was tailored to Walton County’s needs and was included in the 2020 Plan. The contractor sent the Committee, including sporadically attending participants, regular emails which contained a Dropbox link to the most updated version of the Plan and encouraged the Committee to thoroughly critique each version. Due to the COVID-19 Pandemic, the 5th and final meeting was held virtually through the Zoom platform. During this meeting, the Hazard Mitigation Plan Update committee completed the review of the previous mitigation strategies, identified new strategies, and reviewed the rough draft of the 2020 Walton County Hazard Mitigation Plan. Walton County’s Hazard Mitigation Plan Update Meeting Dates: Friday, September 27, 2019 Kick-Off Meeting Friday, October 25, 2019 Hazard Identification and Prioritization; Update Critical Facilities Information Friday, January 24, 2020 Analysis of Hazard Profile Research; Review and Edit 2016 Hazard Mitigation Strategies (Public Meeting ---PAGE BREAK--- 25 I Page Walton County Hazard Mitigation Plan Update 2020 Friday, February 28, 2020 Continue to Review and Edit 2016 Hazard Mitigation Strategies; Identify New Hazard Mitigation Strategies (Public Meeting Wednesday, July 29, 2020 Continue to Review and Edit 2016 Hazard Mitigation Strategies; Risk Assessment Analysis; Presentation of 2019 Hazard Mitigation Plan - Rough Draft (*Virtual Meeting due to Covid-19 pandemic) Each section of Walton County’s 2016 Hazard Mitigation Plan has been revised in some manner. Therefore, a summary of those changes will be listed in the first section of each chapter. Significant additions/modifications to this Plan include the following: • Tropical Cyclone added to Natural Hazards • Extreme Temperatures added to Natural Hazards • Infrastructure Failure added to Technological Hazards • Communications Failure removed as a stand-alone hazard and incorporated into Infrastructure Failure • Emerging Infectious Diseases added to Technological Hazards ---PAGE BREAK--- 26 I Page Walton County Hazard Mitigation Plan Update 2020 Hazard Mitigation Plan Update Participants Requirement §201.6(b)(2) The following 81 participants contributed to the update of Walton County’s 2016 Hazard Mitigation Plan: (in alphabetical order) David Adcock Supervisor City of Social Circle Street Department John H.

Witcher Citizen; Former Councilmember; Former Interim Mayor City of Walnut Grove Greg Yevick Director of Facilities Walton County School District The Plan Update Committee relied on their consultant to guide them through the update process. During meetings, the participants had productive discussions, expanded their professional networks, asked thoughtful questions, made important decisions, and provided critical input during key stages in the update process. Efforts were made to involve all county and municipal departments, as well as community organizations and local businesses, that may have a role in the implementation of mitigation actions and/or policies. These efforts included sending invitations via email to attend the Kick-off Meeting, sending reminder emails before each upcoming meeting, emailing pertinent information throughout the process, and requesting the review and critique of each chapter in the updated Plan. The municipalities of Between and Jersey did not have direct representation who attended meetings of the Walton County Hazard Mitigation Planning Committee. Both municipalities were included in all communication regarding the planning ---PAGE BREAK--- 34 I Page Walton County Hazard Mitigation Plan Update 2020 process, invitation emails, and drafts sent by both Lux Mitigation and Planning and Walton County Emergency Management Agency. However, Walton County provides most services, include emergency management, fire protection, and law enforcement, for these two municipalities. As such, representation of Between and Jersey was provided by EMA Director Carl Morrow, Walton County Sheriff’s Office Uniform Patrol Division Captain Ty Vance, and Walton County Fire Chief Kevin Haney during the meeting process. In August 2020, Jersey and Between were provided a “City/Town Worksheet” and a copy of the updated Walton County Hazard Mitigation Plan to ensure their participation in the process and their review of the document. Upon completion, information provided by the municipalities, including capabilities and services, notable past hazard events, and any new municipal-specific strategies were added to the 2020 Walton County Hazard Mitigation Plan. Mayor Robert J. Post completed this participation document on behalf of the Town of Between. City Clerk Susan Head completed this participation document on behalf of the Town of Jersey. All neighboring counties – Barrow, Gwinnett, Morgan, Newton, Oconee, and Rockdale – were asked to peer review the 2020 Mitigation Plan draft. The Plan was sent to each County EMA office. Walton County had significant support and contribution to the Hazard Mitigation Plan Update process from surrounding jurisdictions. Representatives from Newton County EMA and Fire Department, the City of Madison (Morgan County), the City of Lawrenceville (Gwinnett County), the City of Winder (Barrow County), and the Gwinnett County Office of Emergency Management all attended meetings of the Walton County Hazard Mitigation Planning Committee and contributed to discussions regarding potential hazards and mitigation strategies. Additionally, the EMA Directors from surrounding counties were asked to attend Plan Update Committee meetings in hopes they would share mitigation ideas from their own counties. ---PAGE BREAK--- 35 I Page Walton County Hazard Mitigation Plan Update 2020 Public Participation Requirement §201.6(b)(1) State Requirement Element F2 Public awareness is a key component of any community’s overall mitigation strategy. As citizens become more involved in decisions that affect their safety, they may develop a greater respect for the natural hazards present in their community, and thus, may take the steps necessary to reduce potential impacts of those hazards. Private citizens participated in the Walton County Hazard Mitigation Plan Update Committee meetings on several occasions throughout the process. Citizens attended the 1st, 4th, and 5th meetings and were full participants in the meeting process. These citizens contributed to the overall review of the mitigation strategies in the previous Walton County Hazard Mitigation Plan and helped to identify new mitigation strategies during the 4th and 5th meetings of the Walton County Hazard Mitigation Plan Update Committee. The following local organizations and businesses participated in the update of Walton County’s 2016 Mitigation Plan: Alternative Energy Southeast, American Red Cross, East Georgia Local Emergency Planning Committee, Hitachi Automotive, Lighthouse World Outreach Center, The Partnership, Piedmont Walton Hospital, Takeda, and the University of Georgia. The Plan Update Committee took it upon themselves to ensure the processes undertaken for the development, implementation, and maintenance of the 2020 Hazard Mitigation Plan adequately considered public needs and viewpoints. A list of public outreach initiatives can be found below: - Email reminders were sent to all Plan Update Committee members, as well as other stakeholders, prior to every meeting. Recipients were encouraged to share the meeting invitation with anyone they thought would be an asset to the Plan Update process or anyone who may want to learn more about what a Hazard Mitigation Plan is. - All of Walton County’s meetings were advertised on the Walton County government calendar, which was visible on the front page of the Walton County, Georgia website. - The January 24, 2020 meeting was advertised on the front page of the Walton County government website in the official government calendar and on the Walton County Government Facebook page. ---PAGE BREAK--- 36 I Page Walton County Hazard Mitigation Plan Update 2020 - The February 28, 2020 meeting was advertised on the front page of the Walton County government website in the official government calendar. ---PAGE BREAK--- 37 I Page Walton County Hazard Mitigation Plan Update 2020 Documentation of Public Meeting Notice Front Page of Walton County website (shows January 2020 and February 2020 meeting information) Walton County Government Facebook Page (January 24, 2020 Meeting Notice) ---PAGE BREAK--- 38 I Page Walton County Hazard Mitigation Plan Update 2020 Multi-Jurisdictional Considerations FEMA does not require cities and towns to adopt a local Hazard Mitigation Plan. However, the Federal DMA 2000 requires that all municipalities, wishing to be eligible to receive Hazard Mitigation Grants through FEMA, must adopt a local multi-hazard mitigation plan and must update that plan every five years. Walton County’s most recent Hazard Mitigation Plan was approved by FEMA in 2016. The 2020 Mitigation Plan is the third five-year update. This FEMA-approved 2020 Hazard Mitigation Plan makes Walton County, the City of Monroe, City of Loganville, City of Social Circle, Town of Between, Town of Good Hope, Town of Jersey, and the Town of Walnut Grove eligible for FEMA’s Hazard Mitigation Grant Program, Flood Assistance Mitigation Grants, and Pre-Disaster Mitigation Grants. As set forth by Georgia House Bill 489, the Emergency Management Agency is the implementing agency for projects pertaining to hazard mitigation. Walton County is dedicated to work in the best interests of the County, as well as, its municipalities. A few mitigation strategies in Walton County’s 2020 Mitigation Plan apply to a specific municipality. Unless noted otherwise, mitigation strategies apply equally to all jurisdictions. During the creation and update of this Plan, Walton County Emergency Management Agency solicited and received participation from the following Walton County municipalities: Monroe, Loganville, Social Circle, Between, Good Hope, Jersey, and Walnut Grove.

Chapter 2 Section Updates Past Hazards • This information involved a review of the hazards listed in the previous plan. • Information was updated for the last 50 years History • Expanded and updated from previous plan Past Events • Identification of major hazard events in Walton County for the last 50 years • Focus on Federal Declarations and events since the last Hazard Mitigation Plan Update Demographics • Updated data to the 2017 Census estimate information Economy • Updated data and information Government • Updated verbiage Municipalities • New Section – Not a standalone section in 2016 Plan Transportation • Updated data and information Climate • Updated data and information Utilities • Updated data and information NFIP Compliance • New Section – Not a standalone section in 2016 Plan ---PAGE BREAK--- 43 I Page Walton County Hazard Mitigation Plan Update 2020 Past Hazards Walton County, Georgia, has faced many natural hazards in its long history. Severe thunderstorms have been the most prevalent of these hazards. In the last 50 years, Walton County has been subjected to 157 documented severe thunderstorm events. These events include torrential rainfall, hail, thunderstorm-force winds, and lightning. Tornadoes, which can sometimes spawn from severe thunderstorms, have also occurred, although with much less frequency. In Walton County, there have been 8 documented tornadoes in the last 50 years. Because of heavy rainfall, either within Walton County or upstream, flooding has also occurred. In the National Climactic Data Center (NCDC) databases of the National Weather Service, there is documentation of 9 flooding events for Walton County. Winter storms and heavy snowfall have affected Walton County over the last 50 years. Because these natural events are barely an annual occurrence, the pre- planning and preparedness component of emergency management is not as robust as northern or western states that routinely see this type of weather. The NCDC recorded 22 winter storms or heavy snow events for Walton County with four of those events occurring in the last five years. Walton County has been impacted by other less severe or less frequent hazards in the past. These hazards include, but are not limited to, the following: drought, excessive heat, tropical cyclones, earthquakes, and wildfires. Walton County has had 11 Presidential Disaster Declarations (FEMA-declared major disasters) – four of which have occurred since the adoption of the 2016 Hazard Mitigation Plan (two for Hurricane Irma in 2017 and two for COVID-19 in 2020). ---PAGE BREAK--- 44 I Page Walton County Hazard Mitigation Plan Update 2020 History Walton County, forty-five miles east of Atlanta in Georgia's Piedmont region, is the state's forty-third county. Comprising 329 square miles, it was created on December 15, 1818, from land originally held by both the Cherokee and Creek Indians and was named for George Walton, a signer of the Declaration of Independence and briefly a Georgia governor. (There was a previous Walton County created by the state legislature in 1803, but its location became part of what is now North Carolina when a dispute over the state line was settled in 1811.) The county seat is Monroe, where the current county courthouse (the third) was built in 1884; since that time the structure has undergone major restorations and additions. According to the 2010 U.S. census, Walton County's population was 83,768, an increase from the 2000 population of 60,687. Monroe, first called Walton Court House, received its new name (honoring the fifth U.S. president, James Monroe) upon its designation as the county seat. The town was incorporated in 1821. Other incorporated communities are Between, Good Hope, Jersey, Social Circle, Walnut Grove, and part of Loganville. The town of Between was incorporated in 1908, though it had been settled during the 1850s. The name was chosen for its location halfway between Monroe and Loganville. Good Hope and Jersey were incorporated in 1905. Good Hope bears the aspirations of its founders in its name. The first non-Indian residents arrived there during the 1830s, settling about a mile east of the town's current location. Jersey was first called Centerville, for its equidistance from the towns of Monroe, Covington (in Newton County), and Social Circle. During the early 1880s, when the townspeople were arranging for a post office, the discovery that another Centerville already existed prompted them to change the town's name. A local merchant and planter, T. M. Abercrombie, had recently imported a Jersey bull, which became the talk of the town, and a half-jokingly made suggestion that the community take its new name from the animal was accepted. Loganville, incorporated as a town in 1887 and then as a city in 1914, was first called Buncombe. It was renamed in 1851 to honor an early settler, James Harvie Logan, who had arrived in 1842, bought sixty-two and a half acres, built a house, and set up shop as a shoemaker. Others soon settled nearby. Loganville is now one of the fastest-growing communities in Georgia, its population having increased by more than 70 percent between 1990 and 2000. Social Circle was founded in 1820 by several men who obtained the land by lottery. It was centered at the junction of two Indian trails known today as Cherokee Road and Hightower Trail (perhaps a corruption of Etowah). Incorporated in 1832 as a village and in 1869 as a town, Social Circle, situated at the highest point of the ---PAGE BREAK--- 45 I Page Walton County Hazard Mitigation Plan Update 2020 Georgia Railroad, was a transportation hub for the area before the Civil War (1861- 65). Its lines were destroyed during the war by Union general William T. Sherman's troops on their March to the Sea, but the town recovered and prospered after the war was over. Walnut Grove was incorporated in 1905 and has been the site of a U.S. post office since 1850. The first settlers in Walton County were almost all farmers, along with an occasional doctor or lawyer. But merchants soon arrived to do business in the area as well. Cotton, various grains, potatoes, and some tobacco were the main cash crops. Cotton mills were the first industry to be established in the county, beginning in the 1840s. These were soon followed by gristmills. Steam mills were established just before the Civil War, but factory work did not become a standard option for employment in the county until after the war. Despite the postwar rise of industry in the county, many of the area's freed slaves became sharecroppers. The 1890s saw a boom in the number of textile mills, leading to prosperity and growth until the devastation wrought by the boll weevil, soil erosion, and the Great Depression of the 1930s caused an economic downturn. The conversion from agriculture to industry picked up again during World War II (1941-45), and the county recovered its economic strength by embracing a diversified manufacturing base. There are twenty-seven sites in Walton County on the National Register of Historic Places. Nineteen of them are in Monroe, including nine historic districts, while the others are shared among some of the smaller towns. The McDaniel-Tichenor House in Monroe was restored as a house museum by the Georgia Trust. ---PAGE BREAK--- 46 I Page Walton County Hazard Mitigation Plan Update 2020 Notable Past Events • 2020, COVID-19 Pandemic (Federal Declaration x2) • 2018, Tornado (EF1) • 2018, Thunderstorm Wind Event • 2017, Tornado (EF1) • 2017, Hurricane Irma (Federal Declaration x 2) • 2014, Severe Winter Storm (Federal Declaration) • 2011, Hail Event • 2009, Hail Event • 2008, Hail Event • 2005, Tornado (F0) • 2005, Thunderstorm Wind Event • 2005, Winter Storm • 2000, Ice Storm (Federal Declaration) • 1997, Thunderstorm Wind Event • 1997, Thunderstorm Wind Event • 1994, Tornadoes (F1 and F0) • 1993, Severe Storms/High Wind Event (Federal Declaration) • 1993, Blizzard (Federal Declaration) • 1990, Tornado (F1) • 1977, Drought (Federal Declaration) • 1973, Tornado (F1) • 1973, Tornado (F3) (Federal Declaration) • 1973, Tornado (F2) ---PAGE BREAK--- 47 I Page Walton County Hazard Mitigation Plan Update 2020 Federal Disaster Declarations Source: Federal Emergency Management Agency (FEMA) ---PAGE BREAK--- 48 I Page Walton County Hazard Mitigation Plan Update 2020 Source: 2019 State of Georgia Hazard Mitigation Strategy and Enhanced Plan ---PAGE BREAK--- 49 I Page Walton County Hazard Mitigation Plan Update 2020 Demographics County 2000 Census 2010 Census 2017 Census Estimates Population 60,687 83,768 88,695 White 83.0% 80.1% 79.0% African American 14.4% 15.6% 16.6% Hispanic/Latino 1.9% 3.2% 4.0% Asian 0.7% 1.1% 1.2% American Indian 0.3% 0.3% 0.2% Two or More Races 0.9% 1.5% 1.5% Median Age 33.9 38.1 38.9 Median Household Income $46,479 $52,369 $55,876 Persons in Poverty 8.0% 13.8% 12.8% Homeowners 76.5% 75.5% 73.0% Municipalities 2000 Census 2010 Census 2017 Census Estimates Monroe 11,407 13,234 13,298 Loganville 5,435 10,438 11,355 Social Circle 3,379 4,262 4,389 Between 148 296 277 Good Hope 210 274 329 Jersey 163 137 116 Walnut Grove 1,241 1,330 1,221 ---PAGE BREAK--- 50 I Page Walton County Hazard Mitigation Plan Update 2020 Economy Walton County’s economy is primarily agricultural with some light industry.

Although each County Commissioner is elected as a representative from their respective districts, they represent the interests of the entire county and all its citizens. The main duties of the Board of Commissioners is to pass local laws, known as ordinances, that regulate a variety of things that promote the health, safety and welfare of the citizens covered by them; to pass a balanced budget each year that funds its own operations as well as to allocate funds to the four Constitutional Officers, other elected officials, the courts and a variety of programs put in place by the State but funded locally; to ensure that necessary services are funded and provided; to set the millage rate for the County government and many other secondary duties. The Board of Commissioners sets the County millage rate each year to fund a portion of the County budget. They also receive the millage rate that is set by the Board of Education and an assessment by the State which is submitted to the Georgia Department of Revenue each year. The Board receives, deliberates and passes local ordinances each year and amends many others to reflect the changing times. Both require that a public hearing be held, and these are normally held during the regular Commission meetings. They also pass several resolutions and proclamations throughout the year. Generally, with some exceptions, the Board can pass any local law and ordinance they feel is needed for the County so long as it does not violate the laws of the State or Federal government or the Constitutional rights of any individual. These are researched thoroughly by legal staff before ever being brought to a hearing. The Board of Commissioners provide many services that citizens expect through the revenues that are raised annually. These include Fire and Ambulance protection; E-911 dispatch services; Zoning and Planning; Inspections; Code Enforcement; Animal Control; Public Library; Public Works; and agencies that service all of these such as Building Maintenance, Vehicle Maintenance, and Emergency Management Services. The budget also funds state mandated services such as Law Enforcement and Detention; Superior, Probate, Magistrate and Juvenile courts; Tax Assessment and Tax Collection services; Elections management; District Attorney (shared with other counties) and some smaller funding for local agencies under the State of Georgia. ---PAGE BREAK--- 52 I Page Walton County Hazard Mitigation Plan Update 2020 Transportation Walton County’s transportation system consists primarily of state highways and county-maintained roads. Interstate 20, US Highways 78 and 278, as well as Georgia State highways 10, 11, 12, 20, 81, 83, 138, and 186 are major transportation routes that carry the majority of passenger and commercial traffic in and out of Walton County. Congestion in these transportation corridors create traffic problems, primarily as a result of population growth. There are no interstate or mass transit systems servicing Walton County. Freight rail lines operated by the Great Walton Railroad and Central of Georgia railroad traverse Walton County. The Monroe-Walton County Airport has one paved 5,000-foot runway that services charter and private aircraft. There are no commercial flights into or out of Monroe- Walton Airport. ---PAGE BREAK--- 53 I Page Walton County Hazard Mitigation Plan Update 2020 Climate Walton County, like much of Georgia, enjoys a temperate climate with four well- defined seasons: warm to hot summers; brisk fall temperatures; relatively brief, cool winters; and a warm spring season. As a result, there exists a long growing season in Georgia, perfect for ornamental and economic-boosting agricultural plants.

The land was fertile from the Apalachee, Alcovy, and Yellow Rivers and newcomers began to settle into the area and work the land. Walton County was laid out by the Lottery Act of 1818, was organized in 1819, and named in honor of George Walton, one of the three Georgians who signed the Declaration of Independence. The first court held in Walton County was at Cow Pens, about three miles southeast of the present courthouse, and Judge John M. Dooley from the northern district presided. Cow Pens is said to have gotten its name from its use at the time by Richard Easley of Athens, GA. Easley owned large herds of cattle and came into possession of lands surrounding the spot where Cow Pens is now located. He sent his herd there to graze, erecting sheds and pens for their protection and later building a log cabin for his herdsmen. Since Easley owned several grazing places, when speaking of this particular place, he would call it the “Cow Pens” and so it became commonly known by that name. Later, the location of a county seat came into question and Walter J. Colquitt, a lawyer, and Dr. Thomas Moody took up their residence at Cow Pens, believing it would be the county seat and the name was consolidated into one word, Cowpens. ---PAGE BREAK--- 56 I Page Walton County Hazard Mitigation Plan Update 2020 At the same time, a doctor by the name of Johnson and a lawyer, whose name is unknown, took up their residence at “Spring Place,” now the City of Monroe. They thought that the county seat would be located there. Elisha Betts of Virginia offered a gift of land for county buildings, private and public cemeteries, and six acres surrounding “Spring Place,” this being a public gathering place for citizens in the surrounding community. This benefactor also suggested to give the town the name of “Monroe” in honor of James Monroe, fifth president of the United States. His offer was accepted, and Monroe became known as the county seat of Walton County in 1820. The City of Monroe was incorporated in 1821. Elisha Betts aided the erection of log and frame houses, stores, and a tavern known as “Major Humphries Assembly Room,” which was used for public meetings, dancing, and other forms of amusement. His own two-story log house is said to have stood on the lot at the corner of Broad and Washington Streets. A fire in 1857 swept the entire downtown area of Broad Street between the streets now known as Spring and Washington. The Courthouse was the only building left standing. Following the fire, the first brick buildings were erected, many of which are still present in one form or another today. The original City Hall building erected during the late 1800's still stands at the corner of Spring Street and Wayne Street, as does the second City Hall which was built in 1939 on South Broad Street. Many other homes and storefronts from the late 1800's and early 1900's still exist here today. Monroe became a bustling cotton/textiles mill town during the early half of the 20th century, as well as attracting local industries and building a strong business presence both downtown and from one end of town to the other. It is known as one of Georgia’s most civil-minded and cultured smaller cities. Monroe also proudly claims the honor of being the “City of Governors,” having furnished seven men to act as Governor of Georgia. Monroe also claims a native son who left Monroe for the West and later became Governor of Texas. The citizens of Monroe are governed by a mayor and eight councilmembers. The mayor is elected citywide and each councilmember is elected by voters in each of the 8 geographic districts. The City of Monroe provides many services to its citizens. These include administrative, code enforcement, economic development, fire protection, law enforcement, sold waste, public works, water, stormwater, wastewater, natural gas, and electric services. Monroe occupies 10.5 square miles and serves as the county seat for Walton County. Monroe has seen steady population growth since its incorporation in the 1820s. ---PAGE BREAK--- 57 I Page Walton County Hazard Mitigation Plan Update 2020 City of Loganville The City of Loganville took its name from James Harvie Logan, who moved to the area from Tennessee in 1842 and purchased of 62.5 acres described as Land Lot No. 186 in the Fourth Land District for the sum of $150.00! Logan was a farmer and shoemaker and built the family home with the help of his son, James Harvie Logan, Jr. During the next several years, as other families settled in the area, the population swelled to about 500 residents. Loganville was first incorporated in 1887 with its original limits extending a half mile in every direction from the well pictured here. Loganville was the last stop on the Seaboard Airline Railroad from Atlanta to Lawrenceville. Local entrepreneurs capitalized on the rail line and built a depot for the Loganville & Lawrenceville Railroad Company in 1898. The Depression shut the railroad down in 1932. The years brought both growth and change. Cotton was no longer king after a bout with the boll weevil which swept through the area. A review carried in the Walton Tribune in 1958 stated: "old buildings have all been replaced by modern business structures: a new bank building, doctor’s building, American Legion, cafés, motel, theatre, cotton warehouse, gins, and many lovely residences. The streets have been paved, waterworks and sewage systems installed, electricity, gas and manufacturing plants built. Nothing adds more to the name of a town than its churches and schools. What more enduring monument could a man desire that his name and ---PAGE BREAK--- 58 I Page Walton County Hazard Mitigation Plan Update 2020 memory be linked with the destiny of a town populated with intelligent, cultured, patriotic and resolute citizens, a majority of whom are united in an endless endeavor to render (Loganville) a highly desirable location for the home-seeker, the manufacturer and the enterprising businessman. Loganville shall continue to grow and expand through the coming years and stand as a monument to the wisdom of the man who selected this place as a site for a town." The City of Loganville is governed by a mayor and six councilmembers. The City of Loganville provides many services to its citizens. These include administrative, planning and development, fire marshal services, law enforcement, public works, water, sanitation, and wastewater. Loganville occupies 7.4 square miles in northwest Walton County and straddles the Walton-Gwinnett County line. The City of Loganville has seen significant population growth since 1980 and has increased its population nearly 6-fold in that time. ---PAGE BREAK--- 59 I Page Walton County Hazard Mitigation Plan Update 2020 City of Social Circle When Mr. Joel Strickland of Tattnall County learned that he had drawn Lot Number 96, First District of Walton County, in the 1820 Lottery, he and his wife, Elizabeth talked it over and decided not to keep the property. Mr. Strickland was soon offered $118 for the 250 acres, and just five days after Christmas, Joel and Elizabeth signed the warranty deed making three men owners of the tract in southern Walton, on which the town of Social Circle was to evolve. The second co-owner ran in into debt and in 1824 his one-third interest was bought at a sheriff’s sale by John P. Blackmon, one of the other original purchasers, for $11 or approximately thirteen cents an acre. Blackmon was able to buy the remaining one-third share, giving him sole ownership. John Blackmon brought and sold several tracts in the new county, but he was especially pleased with Lot Number 96. On this property was an excellent spring, near which the important north-south Rogue Road was intersected by the best- known route from the southwestern part of the county, Hightower Trail. Near the latter’s ford on the Alcovy was the recently vacated campsite of a band of Creek Indians, whose choice of the location in itself spoke well for the region’s fertility and comfort. Blackmon added his own dwelling to those standing near the crossroads and donated a nearby parcel as site for a Methodist Church. Soon a small storehouse, the meeting house, and a shop gave the little settlement 10 miles south of the county seat the semblance of a village. It was a likely spot for business, for at the junction of the two old routes travelers often paused to rest, friends frequently met, either by design or accident, and newly formed acquaintances were often renewed by the patterns of their travel habits. ---PAGE BREAK--- 60 I Page Walton County Hazard Mitigation Plan Update 2020 Legend says that the settlement received its name when a new traveler, impressed by the exuberant hospitality of a little group of congenial pioneers, remarked enthusiastically, “This sure is a social circle!” This may be true; however, a less colorful explanation should not be ignored. Another community by the name of Social Circle was brought to this section by a former citizen of the older village. Early in January 1826, Blackmon and Augustine B. Pope stuck a chestnut stake in the ground and measured off an acre to include the shop already standing. Blackmon specified in the sale of the property that Pope “not carry on any business of a public nature only such pertains exclusively to an apothecary (drug) shop.” The two men had discussed a site for a post office on the settlement and, on January 5, 1826, government authorization came through. John Blackmon was designated as Social Circle’s first postmaster. In 1832, Social Circle was incorporated. New settlers continued to move in, and, in June 1836, Mr. John Dally opened a grocery store in the city limits. During 1845, the Georgia Railroad reached this community as it advanced westward. The coming of the railroad was probably the most influential event in Social Circle’s early history and marked this city as the county’s first rail center. A Masonic Lodge was established in 1848 and the first officer was the engineer who had surveyed for the Georgia Railroad. In 1869 Social Circle was incorporated as a town and limits extended to one-half mile from the center of town in all directions. Town ordinances of 1869 required merchants to close at 10:00 p.m. and any person found on the streets thereafter must give a satisfactory account of himself or spend the night in the guard house. Playing marbles on the Sabbath was prohibited and sale of liquor on election days was illegal. Fines were given out for cock fighting, fastening horses to shade trees or fences and for riding a horse in a “disorderly manner.” The head of each household was required to keep a strong ladder long enough to reach the top of the highest building on his lot as a precautionary measure in case of fire, and dwellings on public streets had to be underpinned as to keep out hogs and help abate the flea nuisance. Social Circle was highly publicized by a Supreme Court case shortly before the turn of the century, when the town became the center of a freight-rate controversy of national importance, where the railroads challenged a finding of the then-relatively new Interstate Commerce Commission. The Court decision in this instance indirectly brought about another challenge of the Commission’s powers, with the result that Social Circle’s name was widely mentioned and repeated across the country for periods of years. ---PAGE BREAK--- 61 I Page Walton County Hazard Mitigation Plan Update 2020 In 1904, Social Circle surrendered her 1869 charter and was subsequently incorporated as a city. Limits were one mile from the public well at the intersection of Madison, Monroe, Covington, and Gibbs Streets. Social Circle is governed by a mayor, who is elected at-large, and four city councilmembers who are elected by district. The City of Social Circle provides many services to its citizens. These include fire protection, law enforcement, bus services, water, wastewater, trash and recycling, and natural gas. Social Circle occupies 11.2 square miles near the southern tip of Walton County and borders Newton County to the west. After having a rather steady population from 1920 to 1970, Social Circle has seen steady growth since that time. Over the last 40 years, the population of Social Circle has doubled. ---PAGE BREAK--- 62 I Page Walton County Hazard Mitigation Plan Update 2020 Town of Between The Town of Between is a uniquely named town in west central Walton County. It has been suggested that the town got its name because it is equidistance between Athens and Atlanta. Other theories suggest that its name was derived by being in between Walton County’s two largest cities – Loganville and Monroe. The population of this small town ebbed and flowed from its incorporation in 1908 until the late 1990s. Since that time, Between has seen dramatic population growth, at least percentage wise. From 1990 to today, Between has seen its population increase 300%. The Town of Between is governed by a Mayor and four council member. All elections are held town-wide and elected officials serve 4-year, staggered terms. The Town of Between mostly provides administrative services and road construction/maintenance services to its citizens. The Walton County Splash Park is currently under construction within the Town limits of Between. The Town of Between occupies less than one square mile. ---PAGE BREAK--- 63 I Page Walton County Hazard Mitigation Plan Update 2020 Town of Walnut Grove The inviting shade of a group of walnut trees was the site of the little store which marked the beginning of one of Walton's older communities. Situated in the extreme western part of the county, approximately nine miles from Monroe, the location is almost equidistant from each of the communities of Loganville, Social Circle, Covington and Conyers. Legend says that Thomas Evans, who set up shop there long ago, referred to the crossroads spot as "the walnut grove." Consequently, this was the appellation used when a post office was established. Walnut Grove is situated on 1.5 square miles and was incorporated in 1905 by the Georgia General Assembly. The town has seen significant growth over the last 25 years and has seen its population increase 4-fold since 1990. The Town of Walnut Grove is governed by a mayor and three councilmembers. Walnut Grove provides a few services to its citizens, including administrative, public works, code enforcement, and sanitation. ---PAGE BREAK--- 64 I Page Walton County Hazard Mitigation Plan Update 2020 Town of Good Hope The Town of Good Hope sits on 1.8 square miles of land in west central Walton County. It was incorporated by the Georgia General Assembly in 1905. Its name is derived from the first settlers having “good hope” their town would grow to become prosperous. Good Hope has seen its population ebb and flow between 150 and 300 since its incorporation. Good Hope is governed by a mayor and five council members. The Town mostly provides administrative services, such as planning and zoning, to its citizens. ---PAGE BREAK--- 65 I Page Walton County Hazard Mitigation Plan Update 2020 Town of Jersey The Town of Jersey occupies 0.8 square miles in southwest Walton County. The town was incorporated in 1905 by the Georgia General Assembly. Jersey has had a steady population between 130 and 200 since its founding. The Town is home to Buckeyes Restaurant. Jersey is governed by a mayor and four councilmembers. All elections are city- wide. The mayor and councilmembers serve four year terms that all expire during the same election cycle. The Town of Jersey provides administrative, fire protection, street construction and maintenance, code enforcement, planning and zoning, utility service, and water services to its citizens. ---PAGE BREAK--- 66 I Page Walton County Hazard Mitigation Plan Update 2020 Chapter Three - hazard Profiles ---PAGE BREAK--- 67 I Page Walton County Hazard Mitigation Plan Update 2020 Summary of Updates for Chapter Three The following table provides a description of each section of this chapter, and a summary of the changes that have been made to the Walton County Hazard Mitigation Plan 2015.

This assessment developed the hazard basis for this plan. The assessment includes the following components for each hazard: 1. Hazard Identification: The Walton County Hazard Mitigation Planning Committee identified nine natural hazards and six technological hazards for this Hazard Mitigation Plan. This is an increase of two natural hazards and one technological hazard from the previous iteration of the plan. Each hazard was identified using statistical data and records from a variety of sources. The list of hazards is based upon frequency, severity of impact, probability, potential losses, and vulnerability. 2. Hazard Description: Each hazard was described in detail. Many hazard descriptions came from the Georgia Hazard Mitigation Plan since many of the hazards that could impact the state could also potentially impact Walton County. 3. Profile of Hazards: Each hazard was profiled as to how it could potentially impact Walton County. 4. Assets Exposed to the Hazard: The plan considers critical facilities and infrastructure as part of the vulnerability assessment. This assessment determines the vulnerability of the municipalities and attempts to identify the populations most vulnerable to each hazard, although many have potential countywide impacts. 5. Estimated Potential Losses: Using critical facility and past history data, an estimation of potential losses due to a particular hazard event were determined. 6. Land Use and Development Trends: Land use trends were considered when determining the potential future impacts of each hazard. This is of particular importance regarding flooding and dam failure events. 7. Multi-Jurisdictional Concerns: Each jurisdiction was considered when determining the potential hazard impact. ---PAGE BREAK--- 70 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Hazard Description This section provides general and historical information about thunderstorms, including high wind, lightning, and hail. Other elements of thunderstorms, such as tornadoes and flooding, are addressed in their own sections. Thunderstorms are formed when moist air near the earth’s surface is forced upward through some catalyst (convection or frontal system). As the moist air rises, the air condenses to form clouds. Because condensation is a warming process, the cloud continues to expand upward. When the initial updraft is halted by the upper troposphere, both the anvil shape and a downdraft form. This system of up-drafting and down-drafting air columns is termed a “cell.” As the process of updrafts and downdrafts feeds the cell, the interior particulates of the cloud collide and combine to form rain and hail, which falls when the formations are heavy enough to push through the updraft. The collision of water and ice particles within the cloud creates a large electrical field that must discharge to reduce charge separation. This discharge is the lightning that occurs from cloud to ground or cloud to cloud in the thunderstorm cell. In the final stage of development, the updraft weakens as the downdraft-driven precipitation continues until the cell dies. Each thunderstorm cell can extend several miles across its base and to reach 40,000 feet in altitude. Thunderstorm cells may compound and move abreast to form a squall line of cells, extending farther than any individual cell’s potential. In terms of temporal characteristics, thunderstorms exhibit no true seasonality in that occurrences happen throughout the year. Convectively, driven systems dominate the summer while frontal driven systems dominate during the other seasons. The rate of onset is rapid in that a single cell endures only 20 minutes. ---PAGE BREAK--- 71 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm However, various cells in different stages of development may form a thunderstorm that lasts up to a few hours as it moves across the surface. In terms of magnitude, the National Weather Service defines thunderstorms in terms of severity as a severe thunderstorm that produces winds greater than 57 mph and/or hail of at least 1 inch in diameter and/or a tornado. The National Weather Service chose these measures of severity as parameters more capable of producing considerable damage. Therefore, these are measures of magnitude that may project intensity. Lightning Lightning occurs when the difference between the positive and negative charges of the upper layers of the cloud and the earth’s surface becomes great enough to overcome the resistance of the insulating air. The current flows along the forced conductive path to the surface (in cloud to ground lightning) and reaches up to 100 million volts of electrical potential. In Georgia, lightning strikes peak in July, with June and August being second highest in occurrence. Hail Hail is a form of precipitation that forms during the updraft and downdraft-driven turbulence within the cloud. The hailstones are formed by layers of accumulated ice (with more layers creating larger hailstones) that can range from the size of a pea to the size of a grapefruit. Hailstones span a variety of shapes but usually take a spherical form. Hailstorms mostly endanger cars but have been known to damage aircraft and structures. ---PAGE BREAK--- 72 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Hazard Profile Severe thunderstorms, including high winds, hail and lightning, are a serious threat to the residents and infrastructure of Walton County. Severe thunderstorms are one of the most frequently occurring natural hazards in Walton County. Many of these storms include high winds, lightning, and hail. Hail up to 3 inches was recorded in Walton County on several occasions, most recently in 2009. Thunderstorm winds of 115 mph have been reported in Walton County, most recently in 1993. While there have been dozens of documented thunderstorm events affecting Walton County over the last 50 years, it is likely that the official number is a low estimate due to poor record keeping in decades past. For example, only 28 thunderstorms events were recorded between 1970 and 1990, likely a vast underestimation of actual events. Most of the available information relating to severe thunderstorm events in Walton County fails to describe damage estimates in any detail. With each thunderstorm event, there are likely unreported costs related to infrastructure costs, public safety response costs, utility repair costs, and personal home and business repair costs. ---PAGE BREAK--- 73 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Thunderstorms have occurred during all parts of the day and night and in every month in Walton County. The Walton County Hazard Mitigation Plan Update Committee utilized data from the National Climatic Data Center, the National Weather Service, numerous weather-related news articles, and the Walton County LEOP in researching severe thunderstorms and their potential impacts on the county. All information has been gathered on a countywide basis. All thunderstorm hazard data included for Walton County is limited to countywide data and is not broken down by jurisdiction. During the last 50 years, 159 thunderstorm events were recorded in Walton County, with 131 of those occurring in the last 30 years. This number includes 62 hail events and only 8 lightning reports. According to these records, Walton County has a 1.2% chance daily of a thunderstorm event based upon data from the last 30 years. Over the last 10 years, Walton County has averaged 4.1 thunderstorm events per year (41 events). Due to improved record keeping protocols, the Walton County Hazard Mitigation Plan Update Committee believes the data from the last ten years provides a more accurate representation of the thunderstorm threat to the county. The Walton County Hazard Mitigation Plan Update Committee has also determined that the lightning threat is severely under-reported, as shown in the NCDC data numbers. For additional historical data, please see Appendix D. The City of Monroe suffered a significant Thunderstorm wind event in February of 1993. This event had reported winds of 115 mph, destroyed 6 homes and 18 businesses, and caused major damage to an additional 154 homes and 21 business as well as several municipal buildings and the county jail in Monroe. Overall, 253 structures suffered damage as a result of this event. The City of Monroe suffered approximately $50 million in damages from this event. As indicated by the below graphics, Walton County averages between 6 and 12 flashes of cloud to ground lightning per square mile per year. That equals a 1.6% to 3.3% chance of a cloud-to-ground lightning strike on any given day. This shows a much higher indication of lightning occurrences than has been reported to the National Weather Service and the National Climatic Data Center. It is the determination of the Walton County Hazard Mitigation Plan Update Committee that this data shows a more accurate representation of the scope of the threat that lightning poses to the citizens and infrastructure of Walton County. ---PAGE BREAK--- 74 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Severe thunderstorm winds, which are defined as winds of at least 58 mph in conjunction with a convective event, have occurred with many thunderstorms that have affected Walton County. These winds can exceed 100 mph and cause damage comparable to weak tornadoes. Below are two maps that identify the wind risk and the hazard wind score for the State of Georgia, including Walton County.

When only the last 30 years are considered, annual estimated damage increases significantly to $1,882167. These numbers are thought to be a gross underestimation of actual past damages. ---PAGE BREAK--- 78 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Source: 2019-2024 State of Georgia Hazard Mitigation Strategy and Enhanced Plan ---PAGE BREAK--- 79 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Land Use & Development Trends Walton County currently has no land use trends related to Thunderstorms beyond continued population growth – particularly in and around the Cities of Loganville and Monroe and in areas of northwest Walton County near the Gwinnett County line. Multi-Jurisdictional Considerations Thunderstorm events have occurred across all areas of Walton County. Crop damage from thunderstorm events would likely have the greatest impact in the rural areas of Walton County. However, property damage numbers would be highest in more heavily populated areas due to greater population density. This is especially true for areas in and around the Cities of Loganville and Monroe and in areas of northwest Walton County near the Gwinnett County line. Additionally, Walton County’s tourism industry could be significantly impacted by thunderstorm events and any widespread damage associated with those events. Thunderstorms have the potential to impact all areas of Walton County. Hazard Summary Thunderstorm events pose one of the greatest threats of property damage, injuries, and loss of life in Walton County. Thunderstorm events are the most frequently occurring weather event that threatens Walton County. As a result, the Walton County HMPC recommends that the mitigation measures identified in this plan for thunderstorms should be aggressively pursued due to the frequency of this hazard and the ability for this hazard to affect any part of Walton County. ---PAGE BREAK--- 80 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Severe Thunderstorm Severe Thunderstorm Events in Walton County Since 2015 Location Date Time Type Mag Dth Inj PrD CrD Totals: 0 0 177.00K 0.00K MONROE 07/05/2016 14:00 Thunderstorm Wind 50 kts.

There are many types of frozen precipitation that could create a severe winter weather event. Freezing rain consists of super cooled falling liquid precipitation freezing on contact with the surface when temperatures are below freezing. This results in an ice glazing on exposed surfaces including buildings, roads, and power lines. Sleet is easily discernable from freezing rain in that the precipitation freezes before hitting the surface. Often this sleet bounces when hitting a surface and does not adhere to the surface. However, sleet can compound into sufficient depths to pose some threat to motorists and pedestrians. A heavy accumulation of ice, which is often accompanied by high winds, can devastate infrastructure and vegetation. Destructiveness in the southern states is often amplified due to the lack of preparedness and response measures. Also, the infrastructure was not designed to withstand certain severe weather conditions such as weight build-up from snow and ice. Often, sidewalks and streets become extremely dangerous to pedestrians and motorists. Primary industries, such as farming and fishing, suffer losses through winter seasons that produce extreme temperatures and precipitation. Severe winter weather exhibits seasonal qualities in that most occur within the months of January to March, with the highest probability of occurrence in February. The rate of onset and duration varies from storm to storm, depending on the weather system driving the storm. Severe winter weather rarely frequents the State of Georgia. However, the impacts of the storms substantiate severe winter weather’s inclusion in the risk assessment. Hazard Profile While winter storms are not as frequent of an occurrence in Walton County as they are in areas in the Northern US, they still have the potential to wreak havoc on the community when they do occur. Winter storms in Walton County typically cause drastic damage to infrastructure, such as roads, power lines, and bridges. They also can cause damage to private property, businesses, and trees throughout the county. The large number of trees in Walton County can also become a hazard when the tree limbs become weighed down with snow and ice and begin to break and fall to the ground, potentially damaging private property, public property, or injuring people and animals. ---PAGE BREAK--- 82 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Winter Storm Source: 2019-2024 State of Georgia Hazard Mitigation Strategy and Enhanced Plan ---PAGE BREAK--- 83 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Winter Storm During the past 25 years, documentation exists for 22 winter storm events in Walton County. No comprehensive data can be located prior to this timeframe. On average, Walton County averages a winter storm every 1.1 years. This equates to an 88% chance of a winter storm occurring in any given year in Walton County. Due to improved record keeping techniques, the HMPC believes that looking at the record for the last 25-year period provides a more accurate representation of the threat of winter storms for Walton County. All winter storm data has been gathered on a countywide basis. For additional historical data, please see Appendix D. All winter storm hazard data included for Walton County is limited to countywide data and is not broken down by jurisdiction. Individual events of Winter Weather can be drastically different depending on many factors, including the duration of the event, the type of precipitation involved, and the depth of the precipitation. Winter Storm events can be a light dusting of snow, ¼ inch of ice, or over a foot of snow. Other factors, such as wind, can influence the strength of these events. In the 1973 and 1993 Winter Storm events, snow accumulations in excess of 10 inches were reported in areas of Walton County with almost all areas receiving over 5 inches of snow.

Estimated Potential Losses Total estimated losses for winter storm events of the last 50 years indicate a total of over $1.1 million in losses. Extrapolated over 50 years, this averages out to $23,880 per year. However, all the documented winter storms with loss information have occurred over the last 20 years. As such, the average loss per year for the last 20 years is $59,700 per year. It is estimated that these numbers are a gross underestimation of the impact of past winter storms and caution is expressed when using these figures to make loss determinations for winter storms in Walton County. Land Use & Development Trends Walton County currently has no land use trends related to Winter Storms beyond continued population growth – particularly around the Cities of Loganville and Monroe and in areas in northwest Walton County near the Gwinnett County line. The large forested areas within Walton County increase the likelihood of major travel impacts as a result of winter storm events. Multi-Jurisdictional Considerations All portions of Walton County could potentially be impacted by a winter storm, including freezing rain, sleet, and snow. Therefore, all mitigation actions identified regarding winter storms should be pursued on a countywide basis and including all municipalities. Hazard Summary Winter storms, which can include freezing rain, sleet, or snow, typically afford communities some advance warning, which is different from many other severe weather phenomena. The National Weather Service issues winter storm watches, advisories, and warnings as much as a day before the storm’s impacts begin. Unfortunately, communities in the Southern United States are oftentimes not equipped to handle winter storms due to their relative infrequent nature. Walton County HMPC recognizes the potential threats winter storms could have on the community and have identified specific mitigation actions as a result. ---PAGE BREAK--- 86 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Winter Storm Winter Storm Events since 2015 in Walton County Location Date Time T.Z.

The causes of flooding include mass sources of precipitation, such as tropical cyclones, frontal systems, and isolated thunderstorms combined with other environmental variables, such as changes to the physical environment, topography, ground saturation, soil types, basin size, drainage patterns, and vegetative cover. Adverse impacts may include structural damages, temporary backwater effects in sewers and drainage systems, death of livestock, agricultural crop loss, loss of egress and access to critical facilities due to roads being washed-out or over-topped and unsanitary conditions by deposition of materials during recession of the floodwaters. Floods are loosely classified as either coastal or riverine. Coastal flooding occurs when normally dry, low-lying land is flooded by sea water. Coastal flooding is usually associated with tropical cyclones in Georgia. Riverine flooding occurs from inland water bodies such as streams and rivers. Riverine flooding is often classified based on rate of onset. The first is slow to build, peak, and recede, often allowing sufficient time for evacuations. The other type of riverine flood is referred to as a “flash” flood, which rapidly peaks and recedes, thus giving insufficient time for evacuations. Flash floods are typically considered the most dangerous. On a broad scale, flooding can occur around any body of water or low-lying surface given enough precipitation or snowmelt. The spatial extent of the flooding event depends on the amount of water overflow but can usually be mapped because of existing floodplains (areas already prone to flooding). Flooding in Georgia is highly dependent on precipitation amounts and is highly variable. Certain seasons are more prone to flooding to a greater likelihood of excessive precipitation. Typically, the wet seasons are during the winter, early spring, and midsummer. Late spring and fall are usually drier seasons. Hazard Profile The Walton County HMPC researched flooding information for the last fifty years. The main sources of information used by the Walton County HMPC came from the National Climatic Data Center, the Walton County Emergency Operations Plan, and news media sources. It was determined that flooding has caused significant damage on many occasions over the last 20 years. One significant flooding event that affected Walton County occurred in 2009. This event was the result of up to 8 inches of rain in Walton County. ---PAGE BREAK--- 88 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Flooding During this event, the Alcovy River reached moderate flood levels and washed out at least one road. While data was collected for the entire 50-year timeframe, little information was available regarding flood events over that period, possibly due to poor record keeping. All flood data was gathered on a countywide basis. Flood events within Walton County are typically associated with areas of special flood hazard as identified on Flood Rate Insurance Maps (FIRMs) published by FEMA. Relatively little information is available regarding flooding damage estimates. However, with each flooding event, it is likely that significant costs arose related to road repair, infrastructure repair, and public safety response operations. Most of the flood damage in Walton County’s history appears to be related to roads and culverts washing out as a result of flood waters. All flooding hazard data included for Walton County is limited to countywide data and is not broken down by jurisdiction. The Brushy Fork Creek gauge near Loganville provides adequate data to show how a flood near that area would impact the jurisdiction. When Brushy Fork Creek reached 9 feet, flood stage begins with the flooding of woodlands and fields from the gauge. At 11 feet, moderate flood stage is reached and outbuildings from the creek begin to be inundated with water. At this point, water will reach the bottom of the bridge on Beaver Road. At 13 feet, outbuildings will be inundated with 2 feet of water and the creek will begin to top the bridge at Beaver Road. At 16 feet, Major flood level is reached, and Brushy Fork Creek will overtop Beaver Road by 3 feet. Outbuildings from the gauge will be under 5 feet of water. For the City of Social Circle, direct flooding impacts would be relatively minor. The most significant potential flooding would likely occur near the Little River tributary along Dove Way and Dove Lane where 3-4 houses would be inundated with up to 6 inches of water. For the Town of Good Hope, the most significant impact would be the flooding of surrounding access points. In a 100-year flood event, Good Hope would only be accessible on Highway 186 from the northeast. All other access points would be blocked. Homes on Pleasant Valley Road would likely face the greatest direct threat from a flood event. One home near Jack’s Creek Tributary could be inundate with up to 2 feet of water. The Town of Between would potentially be cut off from the rest of Walton County during a 100-year flood event as Highway 78 would become blocked to the northwest and southeast. Direct impacts for residents in the Town of Between ---PAGE BREAK--- 89 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Flooding would likely be limited to crawl spaces and basements potentially seeing 2-3 inches of water on New Hope Church Road. The Town of Walnut Grove would potentially have a few homes directly impacted by a 100-year flood event. Homes on Cambridge Drive, Emerald Drive, and Greenhill Way could be inundated with 2-3 inches of water, which would mostly impact non-living spaces such as garages and basements. The City of Loganville could see significant direct impacts from a flood event, although most of the damage would likely be in the Gwinnett County side of the city. For the Walton County side of Loganville, impacts would likely include homes on Bay Creek Falls and Bay Creek Lodge being impacted by up to 6 inches of water. Additionally, Homes on Ivy Creek Drive, Doe Lane, and Tucker Lane could all be impacted by 2-3 inches of water, although most of these impacts would be in non-living areas of the homes such as garages and basements. The City of Monroe is the Walton County municipality most susceptible to direct flooding impacts. In a 100-year flood event, water levels from Mountain Creek would likely reach 2-3 feet deep on West Springs Street near Mountain View Drive and several businesses would be inundated with up to 2 feet of water. Additionally, many homes in the area of Grubby Creek and the Grubby Creek Tributary (Ash Lane, West Creek Circle, Kendall Court, Mill Stone Bluff, Store House Court, Old Mill Point and Wheel House Lane) would be inundated with up to 1 foot of water. There is no 100-year floodplain area in the Town of Jersey. Flood events are limited to heavy rain events with local ponding of water in low-lying areas that have little to no impact on the community. There are 10 documented flood events over the last 50 years. Based on the 50-year record, it can be inferred that such an event is likely to occur every 5 years in Walton County. This relates to a 20% chance of a flood event occurring in a given year. However, all flooding events have occurred over the last 20 years. This would increase the documented likelihood of a flooding event to 50%. Walton County’s unincorporated areas, particularly those along the Alcovy River in central Walton County and Apalachee River in eastern Walton County, are most at risk for riverine flood events. The municipality most at risk for these types of flood events is the City of Monroe due to the proximity of the Alcovy River and Mountain Creek to the western areas of Monroe. For the municipalities of Loganville, Social Circle, Jersey, Between, Good Hope, and Walnut Grove, flash flooding events caused by significant rainfall occurring in a short period of time is the most likely source of direct flood impacts in these jurisdictions. ---PAGE BREAK--- 90 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Flooding For additional historical data, please see Appendix D. Assets Exposed to the Hazard To evaluate the assets that would potentially be impacted by flooding, the Walton County HMPC attempted to identify known structures within, or close to, the 100- year floodplain.

Extrapolated over 50 years, this results in an annual average of $180 per year. However, all reported damages have occurred in the last 10 years. As a result, the average over the last 10 years is $900 annually.

The County (CID No. 130185B) first entered the NFIP on February 16, 1990. According to the NFIP guidelines, the County has executed a Flood Damage Prevention Ordinance. This ordinance attempts to minimize the loss of human life and health as well as minimize public and private property losses due to flooding. The ordinance requires any potential flood damage be evaluated at the time of initial construction and that certain uses be restricted or prohibited based on this evaluation. The ordinance also requires that potential homebuyers be notified that a property is located in a flood area. In addition, all construction must adhere to the Georgia State Minimum Standard Codes and the International Building Codes. Currently, the Walton County municipalities of Between, Good Hope, Loganville, Monroe, Social Circle, and Walnut Grove also participate in NFIP through the application of appropriate NFIP-compliant ordinances and regulations. There are no 1% (100-year) flood plain areas in the Town of Jersey. There are two residential repetitive loss properties identified in Walton County. These properties have a total loss value of $66,794. Multi-Jurisdictional Considerations During a large-scale flood event, many portions of Walton County would potentially be impacted by flooding. However, the area’s most prone to flooding have historically been those areas located within the 100-year floodplain – particularly those areas along the Alcovy and Apalachee Rivers and their tributaries and distributaries. All of Walton County, including all municipalities, could potentially be impacted. Hazard Summary Flooding has the potential to inflict significant damage within Walton County, particularly along the Alcovy and Apalachee Rivers and their tributaries and distributaries. However, the Walton County HMPC recognizes the significant threat that flash flooding poses to Walton County due to the local topography. Mitigation of flood damage requires the community to be aware of flood-prone areas, including roads, bridges, and critical facilities. The Walton County HMPC identified flooding as a hazard requiring mitigation measures and identified specific goals, objectives, and action items they deemed necessary to lessen the impact of flooding for their communities. These maps were updated since the previous plan. There are 2 repetitive loss properties identified in Walton County. ---PAGE BREAK--- 95 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Flooding Flood Events since 2015 in Walton County Location Date Time T.Z.

Exceptionally large tornadoes may not exhibit the classic “funnel” shape, but may appear as a large, turbulent cloud near the ground or a large rain shaft. Destructive because of strong winds and windborne debris, tornadoes can topple buildings, roll mobile homes, uproot vegetation and launch objects hundreds of yards. Most significant tornadoes (excluding some weak tornadoes and waterspouts) stem from the right rear quadrant of large thunderstorm systems where the circulation develops between 15,000 and 30,000 feet. As circulation develops, a funnel cloud, a rotating air column aloft, or tornado descends to the surface. These tornadoes are typically stronger and longer-lived. The weaker, shorter-lived tornadoes can develop along the leading edge of a singular thunderstorm. Although tornadoes can occur in most locations, most of the tornado activity in the United States in the Midwest and Southeast. Tornadoes can occur anywhere within the State of Georgia. In terms of the continuum of area of impact for hazard events, tornadoes are fairly isolated. Typically ranging from a few hundred to one or two miles across, tornadoes affect far less area than larger meteorological events such as tropical cyclones, winter storms and severe weather events. An exact season does not exist for tornadoes. However, most occur between early spring to mid-summer (February-June). The rate of onset of tornado events is rapid. Typically, the appearance of the first signs of the tornado is the descending funnel cloud. This sign may be only minutes from the peak of the event, giving those in danger minimal sheltering time. However, meteorological warning systems attempt to afford those in danger more time to shelter. The frequency of specific tornado intensities is undetermined because no pattern seems to exist in occurrence. Finally, the duration of tornado events ranges from the few minutes of impact on a certain location to the actual tornado lasting up to a few hours. Tornadoes are measured after the occurrence using the subjective intensity measures. The Enhanced Fujita Scale describes the damage and then gives estimates of magnitude of peak 3-second gusts in miles per hour. ---PAGE BREAK--- 102 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Tornado Hazard Profile All areas within Walton County are vulnerable to the threat of a tornado. Due to the indiscriminate and unpredictable nature of tornadoes, there is no reliable method to determine where or when a tornado will strike. There have been 8 documented tornadoes in the last 50 years in Walton County. It is likely that other tornadoes have occurred within this timeframe, but available records are limited in nature. Based on the 50-year information available for Walton County, a tornado occurs every 6.25 years. On an annual basis, Walton County has a 16% chance of being impacted from a tornado event.

This holds true for Walton County, as well. The strongest documented tornado to impact Walton County was EF3 in 1983. This storm traveled 8.9 miles through Walton and Oconee Counties and caused damages in excess of $25 million. The costliest tornado to ever impact Walton County occurred in 1973. This F2 tornado was on the ground for 22 miles through north central Walton County. Damages for this tornado exceeded $250 million. The Walton County Hospital reported treating over 100 patients as a result of this storm. For additional historical data, please see Appendix D.

Additionally, tourist areas throughout Walton County would see significant impact from a direct tornado strike or damage in infrastructure from a tornado strike elsewhere in Walton County. Multi-Jurisdictional Considerations All portions of Walton County could potentially be impacted by a tornado due to the indiscriminate nature of tornadic events. Therefore, all mitigation actions identified regarding tornadoes should be pursued on a countywide basis and included all municipalities. Hazard Summary Walton County remains at risk to potential damage from tornadoes, especially considering the average of one tornado every 6.25 years over the last 50 years. Should a tornado strike in densely populated areas of the county, significant damage or loss of life could occur.

This deficiency results in a water shortage for some social or environmental sector. Drought should be judged relative to some long-term average condition of balance between precipitation and evapotranspiration in a particular area that is considered “normal.” Drought should not be viewed as only a natural hazard because the demand people place on water supply affects perceptions of drought conditions. From limited water supplies in urban areas to insufficient water for farmland, the impacts of drought are vast. Droughts occur in virtually every climatic zone and on every continent. Because the impacts of drought conditions are largely dependent on the human activity in the area, the spatial extent of droughts can span a few counties to an entire country. Temporal characteristics of droughts are drastically different from other hazards due to the possibility of extremely durations as well as a sluggish rate of onset. Drought conditions may endure for years or even decades. This factor implicates drought as having a high potential to cause devastation on a given area. The duration characteristic of droughts is so important that droughts are classified in terms of length of impact. Droughts lasting 1 to 3 months are considered short term, while droughts lasting 4 to 6 months are considered intermediate and droughts lasting longer than 6 months are long term. With the slow rate of onset, most populations have some inkling that drought conditions are increasingly present. However, barring drastic response measures, most only must adapt to the changing environment. Seasonality has no general impact on droughts in terms of calendar seasons. However, “wet” and “dry” seasons obviously determine the severity of drought conditions. In other words, areas are less susceptible to drought conditions if the area is experiencing a wet season. The frequency of droughts is undetermined, since the hazard spans such a long period of time. However, climatologists track periods of high and low moisture content similarly to the tracking of cooling and warming periods. Hazard Profile The Walton County HMPC reviewed data for the last 50 years regarding drought conditions. Historically, agricultural losses have accounted for the vast amount of losses related to drought conditions. ---PAGE BREAK--- 109 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Drought Due to poor record keeping and the unpredictable nature of drought conditions, reliability of historical data for the last 50 years is low. Walton County has been impacted by 8 drought events in the last 20 years, according to data from the National Climatic Data Center. This amounts to a 40% chance of a drought for a given year over the last 20 years. The economic impact of these droughts, including crop damage, is not available for most of these droughts. However, documentation does show over $6 million in crop losses due to the 2000 drought and $1.5 million in losses for the 1997 drought. This is the only drought with documented economic loss estimations. All drought hazard data included for Walton County is limited to countywide data and is not broken down by jurisdiction. There have been two recent examples of “exceptional” drought events affecting Walton County. These events occurred in 2007 and 2016. Both events reached the D4 (Exceptional Drought) designation, according to data from the United States Drought Monitor. Below are maps of these two events. Source: USDA Drought Monitor – University of Nebraska-Lincoln ---PAGE BREAK--- 110 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Drought Source: USDA Drought Monitor – University of Nebraska-Lincoln Events of this extent can cause water shortages for residential and corporate needs, as well as affecting the ability for firefighting operations to be properly effective. Drought conditions of this extent can have devastating effects on the local agricultural industries, which has occurred in previous D4 level droughts. Assets Exposed to the Hazard While drought conditions do not typically pose a direct threat to structures, secondary hazards from drought such as increased wildfire threat, does pose a significant threat to all public and private property in Walton County, including all critical facilities. Water resources could also become scarce during a drought, a condition that would potentially affect all Walton County residences and critical facilities. Estimated Potential Losses No damage to structures or critical facilities is expected as a direct result of drought conditions. However, crop damage and subsequent losses can be expected to occur as a result of drought conditions. The degree of losses would depend on the duration of the drought, severity of the drought, temperatures during the drought, season in which the drought occurs, and the specific needs of the involved crops. Water system shortages and need for supply assistance for those systems could also lead to economic losses associated with the drought. ---PAGE BREAK--- 111 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Drought According to the 2017 Agriculture Census data, Walton County’s market value of products sold was $26,613,000. $6,134,000 of that total represented crop sales, accounting for 23% of the total. Livestock sales accounted for 77%, or $20,479,000, of the total value.

This increased pull on these resources in Walton County could quicken or deepen the impacts of a drought for residential, commercial, and industrial areas. Additionally, the local crop industry could see particularly significant impacts from a drought. With over $60 million in annual sales, crop damage as a result of a prolonged drought could prove to be particularly crippling to the Walton County economy. Multi-Jurisdictional Considerations All portions of Walton County could potentially be impacted by a drought, but agricultural areas of the county are potentially more at risk. Therefore, all mitigation actions identified regarding drought should be pursued on a countywide basis and include all municipalities. ---PAGE BREAK--- 113 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Drought Hazard Summary Drought conditions can cause significant economic stress on the agriculture and forestry interests of Walton County. The potential negative secondary impacts of drought are numerous. They include increased wildfire threat, decreased water supplies for residential and industrial needs, stream-water quality, and water recreation facilities. The Walton County HMPC recognizes the potential threats drought conditions could have on the community and have identified specific mitigation actions as a result.

Wildfires can consume large areas, including infrastructure, property, and resources. When massive fires, or conflagrations, develop near populated areas, evacuations could possibly ensue. Not only do the flames impact the environment, but the massive volumes of smoke spread by certain atmospheric conditions also impact the health of nearby populations. Wildfires result from the interaction of three crucial elements: fuel, ignition (heat), and oxygen. Natural and manmade forces cause the three crucial elements to coincide in a manner that produces wildfire events. Typically, fuel consists of natural vegetation. However, as the urban and suburban footprint expands, wildfires may utilize other means of fuel, such as buildings. In terms of ignition or source of heat, the primary source is lightning. However, humans are more responsible for wildfires than lightning. Manmade sources vary from the unintentional, such as fireworks, campfires or machinery, to intentional arson. With these two elements provided, the wildfires may spread as long as oxygen is present. Weather is the most variable factor affecting wildfire behavior. Strong winds propel wildfires quickly across most landscapes unless firebreaks are present. Shifting winds create erratic wildfires, which can complicate fire management efforts. Dry conditions provide faster-burning fuels, either making the area more vulnerable to wildfire or increasing the mobility of preexisting wildfires. Wildfires are notorious for spawning secondary hazards, such as flash flooding and landslides, long after the original fire is extinguished. Both flash flooding and landslides result from fire consuming the natural vegetation that provides precipitation interception and infiltration as well as slope stability. All of Georgia is prone to wildfire due to the presence of wildland fuels associated with wildfires. Land cover associated with wildland fuels includes coniferous, deciduous, and mixed forest; shrubland; grassland and herbaceous; transitional; and woody and emergency herbaceous wetlands. The spatial extent of wildfire events greatly depends on both the factors driving the fire as well as the efforts of fire management and containment operations. ---PAGE BREAK--- 115 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Wildfire In terms of seasonality, wildfires can occur during any season of the year. However, drier seasons, which vary within the State of Georgia, are more vulnerable to severe wildfires because of weather patterns and the abundant quick- burning fuels. In terms of rate of onset and duration, wildfires vary depending on the available fuels and weather patterns. Some wildfires can engulf an area in a matter of minutes from the first signs whereas others may be slower burning and moving. The frequency of wildfires is not typically measured because of the high probability of human ignition being statistically unpredictable. Magnitude and intensity are typically only measured by size of the wildfire and locations of burning. Three classes of fires include understory, crown, and ground fires. Naturally- induced wildfires burn at relatively low intensities, consuming grasses, woody shrubs, and dead trees. These understory fires often play an important role in plant reproduction and wildlife habitat renewal and self-extinguish due to low fuel loads or precipitation. Crown fires, which consist of fires consuming entire living trees, are low probability but high consequence events due to the creation of embers that can be spread by the wind. Crown fires typically match perceptions of wildfires. In areas with high concentrations of organic materials in the soil, ground fires may burn, sometimes persisting undetected for long periods until the surface is ignited. Hazard Profile Wildfires pose a serious threat to Walton County. This is a result of the high amount of forestland and vegetation available to fuel potential wildfires. Also, there is an increasing amount of wildland-urban interface (WUI) in Walton County, which is defined as areas where structures and other human development meets undeveloped wildland properties. 99.3% of Walton County’s population lives within the WUI.

However, according to the 2018 Georgia Forestry Commission Walton County Community Wildfire Protection Plan, Walton County had 183 wildfires from 2007-2017 – an average of 16.6 fire per year. This equates to a 4.6% chance of a wildfire on any given day in Walton County. These 183 wildfires burned a total of 505.2 acres – or 45.93 acres per year. For this timeframe, debris burning was the most common cause of fire and was the source of 34% of wildfires from 2007 to 2017. Georgia Wildfire Ignition Density Source: Southern Group of State Foresters Wildfire Risk Assessment Portal Assets Exposed to the Hazard All public and private property located within the Wildland-Urban Interface, including critical infrastructures, are susceptible to impacts from wildfires. Due to the large area of wildland area in Walton County and the large amount of WIU, all public and private property, including critical infrastructures, could be directly or indirectly impacted by the threat of wildfire. ---PAGE BREAK--- 117 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Wildfire Estimated Potential Losses Little information is available regarding damages, in terms of dollars, for wildfire losses in Walton County. According to the 2017 Ag Census by the USDA, Walton County has $6,134,000 in annual crop sales. These areas would potentially be impacted by a wildfire event. Fire Occurrence Map for Walton County (2007-2016) Land Use & Development Trends With the continued increase in population, Wildland-Urban Interface (WUI) is increasing in Walton County. The WUI creates areas where fire can easily move from wildland areas into developed areas and threaten structures and human life. The expansion of the WUI in Walton County complicated wildland fire management operations and planning initiatives. This development trend is expected to continue in the future. Multi-Jurisdictional Considerations All portions of Walton County, including all municipalities, could potentially be impacted by a wildfire due to the large amount of Wildland-Urban Interface, but the less developed areas of the county are more vulnerable. Therefore, all mitigation actions identified regarding wildfires should be pursued on a countywide basis and include all municipalities. ---PAGE BREAK--- 118 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Wildfire Hazard Summary Wildfire is a significant threat to Walton County due to the increased amount of Wildland-Urban Interface.

This release typically manifests on the surface as ground shaking, surface faulting, tectonic uplifting and subsidence, or ground failures, and tsunamis. In the United States, earthquake activity east of the Rocky Mountains is relatively low compared to the Western states because it is away from active plate boundaries and the plate interior strain rates are known to be very low. The physical property of earthquakes which cause most of the damage within the United States is ground shaking. The vibrations from the seismic waves that propagate outward from the epicenter may cause failure in structures not adequately designed to withstand earthquakes. Because the seismic waves have different frequencies of vibration, the waves disseminate differently through sub-surface materials. For example, high frequency compression and shear waves arrive first, whereas lower frequency Rayleigh and love waves arrive later. Not only are the speeds varied between seismic waves, but also the types of movement. The surface vibration may be horizontal, vertical, or a combination of the two, which causes a wider array or structures to collapse. Another manifestation of earthquakes is surface faulting. This phenomenon is defined as the offset or tearing of the earth’s surface by a differential movement across a fault. Structures built across active faults tend to sustain damage regularly. There are no active faults within or near Georgia. Distinct inactive faults are known within the state north or the Columbus to Macon to Augusta fall line and running generally northeast-southwest. The third earthquake phenomenon that causes damage is tectonic uplift and subsidence. Tectonic uplift can cause shallowing of the harbors and waterways while tectonic subsidence can cause permanent or intermittent inundation. Due to the association of tectonic uplift and subsidence with active faults, Georgia is not at risk to these phenomena. The fourth earthquake damage-causing phenomena are earthquake-induced ground failures, including liquefaction and landslides. During an earthquake, the areas that are rich in sand and silt have groundwater within 30 feet of the surface temporarily behave as viscous fluids during strong ground shaking. Structures built on these materials can settle, topple, or collapse as the ground “liquefies” beneath it. Landslides can also form when earthquake shaking or seismic activity dislodges rock and debris on steep slopes, triggering rock falls, avalanches, and slides. ---PAGE BREAK--- 132 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Earthquake Also, unstable, or nearly unstable slopes, consisting of clay soils, may lose shear strength when disturbed by ground shaking and fail, resulting in a landslide. Georgia is at very low risk of seismic induced liquefaction or landslides. The last of the earthquake-induced phenomena are tsunamis, which are large, gravity-driven waves triggered by the sudden displacement of a large volume of water. The waves produced travel in all directions from the origin at speeds of up to 600 miles per hour. In deep water, tsunamis normally have small wave heights. However, as the waves reach shallower water near land, the wave speed diminishes, and the amplitude drastically increases. Upon impact with a shoreline, the waves can inundate land rapidly, engulfing everything in its path. Successive wave crests follow, typically arriving minutes to hours later, frequently with later arrivals being more dominant. Frequently, the first tsunami waves are downward, causing dramatic exposure of the beach. Because of this, people are often killed trying to collect newly exposed seashells when the positive waves then arrive. Although large tsunamis are rare in the eastern coast of the US, the possibility of such events occurring anywhere along the Atlantic and Gulf coast exists.

In reviewing data of the last 50 years, no earthquakes have originated from within Walton County. However, earthquakes with a magnitude of 2.0 or greater have occurred as close as 14 km ENE of Madison GA (2019). 14 earthquakes have originated within 50 miles of Monroe, GA in the last 50 years. The strongest earthquake to occur within this radius was a 2.6 that occurred near Eatonton, GA in 2015. This equates to a 28% chance of an earthquake occurring from within 50 miles of Walton County in any given year. Historically, the 1886 Charleston, SC earthquake, estimated to be between 6.6 and 7.3 on the modern Richter Scale, likely caused impacts to Walton County. Although no historical records exist exhibiting any damages, Walton County was estimated to be in a level VI area of the Modified Mercalli Intensity scale for this event. This would indicate strong shaking felt by everyone inside and outside at the time of the event and characterized by broken windows, movement of heavy furniture, and slight to moderate damage for poorly built buildings. Even with this low number of occurrences, it was determined that if earthquakes occur within or close to the jurisdiction of Walton County, significant damage could occur. Therefore, the Walton County HMPC has determined the threat of earthquakes to be higher than the statistics would indicate.

Tropical Disturbance: A discrete tropical weather system of apparently organized thunderstorms – generally 100 to 300 nautical miles in diameter – originating in the tropics or subtropics, and maintaining its identity for 24 hours or more. Tropical Depression: An organized system of clouds and thunderstorms with a defined circulation and maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm: An organized system of strong thunderstorms with a defined circulation and maximum sustained winds of 39 mph to 73 mph (34-63 knots). Hurricane: An intense tropical weather system with a well-defined circulation, producing maximum sustained winds of 74 mph (64 knots) or greater. Hurricane intensity is classified into five categories using the Saffir-Simpson Hurricane scale. Winds in a hurricane range from 74-95 mph for a Category 1 hurricane to greater than 156 mph for a Category 5 hurricane. ---PAGE BREAK--- 137 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Tropical Cyclone Tropical cyclones can cause catastrophic damage to coastlines and areas several hundred miles inland. Tropical cyclones can produce sustained high winds and spawn tornadoes and microbursts. Additionally, tropical cyclones can create storm surges along the coast and cause extensive damage from heavy rainfall. Floods and flying debris from the excessive winds are often the deadly and destructive results of these weather events. Slow moving tropical cyclones traveling into mountainous regions tend to produce especially heavy rain. Excessive rain can trigger landslides or mudslides. Flash flooding can also occur due to intense rainfall. Each of these hazards present unique characteristics and challenges; therefore, the following have been separated and analyzed as individual hazards: Tropical cyclones, Thunderstorms, Tornadoes, and Flooding. This section will focus on the direct effects of tropical cyclones. ---PAGE BREAK--- 138 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Tropical Cyclone Hazard Profile Tropical cyclones have directly impacted Walton County on an infrequent basis over the last 50 years. However, the possibility of a hurricane or tropical storm retaining their wind strength as far inland as Walton County is possible. There have been 15 documented impacts from Topical Cyclones in Walton County. This equates to a 30% chance of a tropical cyclone impacting Walton County in any given year. The Walton County Hazard Mitigation Update Committee believes this percentage is more representative of the potential impact. Two tropical cyclones – Tropical Storm Beryl in 1994 and Tropical Storm Jerry in 1995 – have had a track that directly dissected Walton County in the last 50 years. All tropical cyclone hazard data included for Walton County is limited to countywide data and is not broken down by jurisdiction. Even with the infrequent occurrences, the impacts that would result from hurricane or tropical storm forces on the citizens, infrastructure, and critical facilities of Walton County could be potentially catastrophic in nature.

Multi-Jurisdictional Considerations All of Walton County, including all municipalities, could potentially be threatened by tropical cyclones. As such, all tropical cyclone mitigation actions should be pursued on a countywide basis and include all municipalities. Hazard Summary Even with the relative infrequency of tropical cyclone impacts in Walton County in the recent past, the potential losses and impacts associated with the event would severely damage the infrastructure and economic viability of Walton County and all municipalities. Walton County’s proximity to the Atlantic coast increases the likelihood of a tropical cyclone impacting the area. The mitigation measures identified in this plan for tropical cyclones should be pursued based on the high impact potential of this hazard and the ability for tropical cyclones to inflict widespread devastation anywhere in Walton County. Walton County has had five Federally Declared Disaster related to Tropical Cyclones, most recently in 2017 (Hurricane Irma). ---PAGE BREAK--- 143 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Extreme Temperatures Hazard Description Extreme temperatures – both hot and cold – can pose a significant threat to an underprepared population. This is particularly true in areas where a population has a large elderly population, a large population of small children, and a population with lower socioeconomic status. The term extreme heat can be subjective to a degree. FEMA, in their “Mitigation Ideas” publication defines extreme heat as “the condition where temperatures consistently stay ten degrees or more above a region’s average high temperature for an extended period.” The key to this definition is, extreme heat is relative to the average temperature, regardless of the time of year. For example, the National Center for Environmental Information (NCEI) records heat events in Georgia with 60- and 70-degree temperatures in December and January, simply because they are significantly higher than the average temperature for that time of year. According to www.ready.gov/heat, FEMA also offers another definition of extreme heat: “In most of the United States, extreme heat is defined as a long period (2 to 3 days) of high heat and humidity with temperatures above 90 degrees.” This definition can also lead to some subjectivity in the term “extreme.” For example, people that live in the southern parts of the country are more adapted to temperatures in the 90s and 100s than people that live in the more northern tiers. This is not to say those temperatures are not still dangerous. Notably, in recent years, more heat related deaths have occurred in the southern tier states than the northern tiers. The National Weather Service, however, focuses on “Excessive Heat,” defining it as heat indices of 105 degrees or more using a combination of temperature and humidity as a “real feel.” Just as extreme heat can be subjective, so can extreme cold. Just as the National Weather Service utilizes heat index to attempt to quantify extreme heat, wind chill is often utilized to quantify extreme cold. Prolonged and/or unprotected exposure to extreme cold can be detrimental to people and animals. Additionally, it can be detrimental to exposed infrastructure, as well. Hazard Profile According to the National Climactic Data Center, Walton County have been exposed to extreme cold/wind chill and excessive heat events on 22 occasions since 1996. This means that Walton County has had 1.1 extreme temperature events per year since 1996. This included 10 extreme cold events and 12 excessive heat events. This averages out to an extreme cold event every 2.4 years (42% annual chance) and an excessive heat event every 2 years (50% annual chance). ---PAGE BREAK--- 144 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Extreme Temperatures In August of 2007, Atlanta had 8 days that cleared 100 degrees and set eight maximum temperature records during the month. On August 22nd, temperatures reached 104 degrees, which set a record for the month of August. The temperature on August 10th was recorded at 105 degrees. The all-time high for Atlanta was set on June 30, 2012 as temperatures reached 106 degrees. Walton County has also been exposed to many extreme cold events. Due to its lower latitude and position within Georgia, Walton County is able to avoid much of the extreme cold temperatures that sometimes plague the mountainous regions of northeast Georgia. However, Walton’s location and lack of widespread exposure to such events increases the impact those events could have if they were to occur. In 2014, an artic front sent temperatures into the single digits across north Georgia, including Walton County. This event was accompanied by high winds, which pushed wind chills to -10 degrees in the early morning hours. ---PAGE BREAK--- 145 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Extreme Temperatures Source: 2019-2024 Georgia Hazard Mitigation Strategy and Enhanced Plan Source: National Weather Service ---PAGE BREAK--- 146 I Page Walton County Hazard Mitigation Plan Update 2020 Natural Hazard: Extreme Temperatures Assets Exposed to the Hazard The Walton County HMPC determined that all critical facilities and all public and private property within Walton County are susceptible to the direct and indirect impacts of an extreme temperature event. Estimated Potential Losses Little information is available regarding damages, in terms of dollars, is available for excessive temperature losses in Walton County. Most losses for these events have been labeled under other impacts, such as drought and severe winter storms. Land Use and Development Trends Walton County currently has no land use trends related to extreme temperatures beyond increased population growth. Multi-Jurisdictional Considerations All of Walton County, could potentially be threatened by extreme temperatures. As such, all extreme temperature mitigation actions should be pursued on a countywide basis. Hazard Summary Incidents of extreme temperatures – both hot and cold – pose a significant threat to the citizens of Walton County. Walton County’s geographical location increases the likelihood of extreme temperature events with extreme heat events generally considered to be more likely. However, the lack of direct preparation for extreme cold events could lead to greater direct impacts. ---PAGE BREAK--- 147 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Hazardous Material Incident Hazard Description Hazardous materials, or hazmat, refers to any materials that may pose a real hazard to human health and/or the environment because of its quantity, concentration, and/or physical or chemical characteristics. Hazardous materials include explosives, flammables, combustibles, oxidizers, toxic materials, radioactive substances, and corrosives. Specific federal and state regulations exist regarding the transport and storage of hazardous materials. A hazardous materials spill or release occurs when a hazardous material gets into the environment in an uncontrolled fashion. Response to a hazmat spill or release depends greatly on the type of material involved and the subsequent physical and chemical characteristics. Major sources of hazardous materials spills include transportation accidents on roadways and railways, pipeline breaches, and spills into rivers and creeks. Jurisdictions with facilities that produce, process, or store hazardous materials are at risk, as are facilities that treat or dispose of hazardous materials. Hazard Profile Data from the United States Coast Guard National Response Center was reviewed regarding hazardous materials spill history in Walton County. Data is available from 1990 to 2019 and all available data was reviewed. There were 37 NRC reported hazardous materials spills or releases in Walton County over a 29-year period. It is anticipated that many more hazardous materials incidents have occurred over the last 29 years but have not been reported. According to the NRC data, Walton County averages 1.3 hazardous materials incidents of a reportable amount every year. The greatest threat for a hazardous materials spill comes from the transportation of materials through Walton County. This is particularly true for the US Highway 78 and 278 corridors that run through the center of the county. Hazardous materials releases can also be the result of railway or fixed facility incidents. Fixed facilities continue to be an increasing concern due to Walton County’s growing industrial footprint. Of particular concern to the Walton County Hazard Mitigation Committee is the exposure of water sources to potential hazardous materials incidents. A spill affecting water sources could have significant impacts on Walton County. ---PAGE BREAK--- 148 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Hazardous Material Incident Assets Exposed to Hazard The environment is particularly vulnerable to the threat posed by hazardous materials. Waterways are at a high risk for contamination from hazardous materials. Water contamination is of particular concern to the Walton County HMPC. Public and private property located near fixed hazardous materials facilities are also a greater risk than the general population of Walton County. Estimated Potential Losses Estimation of potential losses is difficult regarding hazardous materials due to the vast array of potential types of hazardous materials that could be involved in the incident and unknown costs regarding environmental damages. No recorded information was found regarding the losses associated with hazardous materials incidents in Walton County. However, a hazardous materials release, whether in transport or at a fixed facility, would incur significant costs regarding emergency response, potential road closures, evacuations, watershed protection measures, expended man-hours, and cleanup materials, equipment, and personnel. Land Use and Development Trends Walton County currently has no land use trends related to Hazardous Materials beyond continued population growth – particularly in and around the Cities of Monroe and Loganville and in areas in northwest Walton County near the Gwinnett County line. Multi-Jurisdictional Considerations All of Walton County, including all municipalities, are vulnerable to both fixed facility and transportation-related hazardous materials releases. However, areas along the US Highway 78 and 278 corridors, including the Cities of Monroe and Loganville and the Town of Between, are at the greatest risk. Hazard Summary Hazardous materials incidents pose a significant threat to the citizens, infrastructure, and critical facilities of Walton County. Unknown quantities of hazardous materials are transported daily through Walton County and all municipalities. These materials are transported via highways, with US Highway 78 being of greatest concern. Water contamination as a result of a hazardous materials spill is of significant concern to the Walton County HMPC. As a result of the threat posed by hazardous materials, the Walton County HMPC has identified mitigation actions directly related to this threat. ---PAGE BREAK--- 149 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Dam Failure Hazard Description Georgia law defines a dam as any artificial barrier, which impounds or diverts water, is 25 feet or more in height from the natural bed of a stream or has an impounding capacity at maximum water storage evaluation of 100 acre-feet or more. Dams are generally constructed to provide a ready supply of water for drinking, irrigation, recreation, and other purposes. Dams can be constructed from earth, rock, masonry, concrete or any combination of these materials. Dam failure is a term used to describe a significant breach of a dam and the subsequent loss of contained water. Dam failure can cause significant damages to structures, roads, utilities, and crops. Dam failure can also put human and animal lives at risk. National statistics indicate that one-third of all dam failures in the United States are caused by overtopping due to inadequate spillway design, debris blocking spillways, or settlement of the dam crest. Another third of all US dam failures are the result of foundation defects, including settlement and slope instability. Hazard Profile There are 3 category I and 28 category II dams located within Walton County. Category I dams are those that would pose a possible threat to human life if a failure were to occur. All category I dams must be inspected annually according to Georgia’s Safe Dams Act. The threat of a dam failure in Walton County could potentially lead to flooding. This flooding would have many of the same hazards as a flood event, but with the onset of such an event being much quicker than in a typical flood event. Assets Exposed to Hazard To evaluate the assets that would potentially be impacted by a dam failure, the Walton County HMPC attempted to identify known structures within, or close to, the 100-year floodplain. All municipalities could be exposed to the hazards of other dams or face secondary hazards from the category I dams. Estimated Potential Losses Loss estimations are not applicable since it is not known which dam will fail and how significant of failure will occur. ---PAGE BREAK--- 150 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Dam Failure Source: 2014 State of Georgia Hazard Mitigation Strategy (most up-to-date version) ---PAGE BREAK--- 151 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Dam Failure Land Use and Development Trends Walton County participates in the National Flood Insurance Program (NFIP) and follows the program’s guidelines to ensure future development is carried out in the best interests of the public. The County (CID No. 130185B) first entered the NFIP on February 16, 1990. According to the NFIP guidelines, the County has executed a Flood Damage Prevention Ordinance. This ordinance attempts to minimize the loss of human life and health as well as minimize public and private property losses due to flooding. The ordinance requires any potential flood damage be evaluated at the time of initial construction and that certain uses be restricted or prohibited based on this evaluation. The ordinance also requires that potential homebuyers be notified that a property is located in a flood area. In addition, all construction must adhere to the Georgia State Minimum Standard Codes and the International Building Codes. Currently, the Walton County municipalities of Between, Good Hope, Loganville, Monroe, Social Circle, and Walnut Grove also participate in NFIP through the application of appropriate NFIP-compliant ordinances and regulations. There are no 1% (100-year) flood plain areas in the Town of Jersey. Multi-Jurisdictional Considerations During a dam failure event, many portions of Walton County would potentially be impacted by flooding. However, the area’s most prone to flooding have historically been those areas located within the 100-year floodplain and from dams. Hazard Summary Dam failure poses a threat to Walton County and its citizens, infrastructure, and critical facilities. A dam failure could prove catastrophic for areas of the dam, particularly if the failure were to occur at any of the 3 Category I or 28 Category II dams located in Walton County. As a result, mitigation efforts for dam failure should be focused in this potentially affected area. ---PAGE BREAK--- 152 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Transportation Incident Hazard Description There are many secondary hazards that could be associated with transportation incidents. Injuries or deaths can occur as a result of the impact of a transportation accident, by a hazardous materials release as a result of a transportation incident, or by other related transportations hazards. Transportation can occur via roadways, highways, interstates, railways, air or navigable waterways. Each transportation type poses their own unique hazard issues and consequences. Roadway hazards are most likely to be caused by a motor vehicle accident involving one or more cars, trucks, vans, or transport vehicles. These incidents can have injuries as a result of the impact of the MVA or a hazardous materials release into the local environment, including waterways. Railway incidents pose many of the same dangers as motor vehicle accidents. However, the threat of a hazardous materials release is greatly increased when railway transportation incidents are considered. Air accidents can include commercial airplanes, private airplanes, hot air balloons, helicopters, or other forms of air travel. Each of these incidents can cause a significant threat to human life as well as posing a hazardous material threat due to the cargo being transported or the fuel being used. Navigable waterway incidents can create formidable incidents for response organizations. Because of the waterway, technical expertise is needed to carry out rescue operations, especially in swift-moving waterways. Also, any incident in a waterway is likely to have environmental impacts. Hazard Profile Transportation incidents are of a significant concern in Walton County. Passing through Walton County are Interstate 20, US Highways 78 and 278, and Georgia Highways 10, 11, 12, 20, 81, 83, 138, and 186. Monroe-Walton County Airport located one mile southeast of downtown Monroe, services Walton County with one asphalt runway. There are no navigable waterways in Walton County. Assets Exposed to Hazard All assets and critical facilities located along or near any transportation route could potentially be impacted by a transportation incident. Areas within Walton County that are not located along or near a transportation route could still face residual impacts. ---PAGE BREAK--- 153 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Transportation Incident Estimated Potential Losses Estimated potential losses cannot be anticipated with this event due to the vast number of differing scenarios regarding transportation incidents. Land Use and Development Trends Walton County currently has no land use trends related to Transportation Incidents beyond an increase in overall population which, in turn, increases the likelihood and potential impact of a transportation incident. The primary areas of growth have been in and around the City of Americus. Multi-Jurisdictional Considerations Walton County as well as all municipalities could potentially be impacted by a transportation incident. However, areas along US Highway 19 are the greatest at risk, including the City of Americus. Hazard Summary The Walton County HMPC has determined that transportation incidents pose a high risk to their jurisdictions due to the unpredictable nature and likelihood of the incident. As a result, the Walton County HMPC has developed mitigation strategies and actions with transportation incidents in mind. ---PAGE BREAK--- 154 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Terrorism Hazard Description The Federal Bureau of Investigation (FBI) defines terrorism as violent acts or acts dangerous to human life that violate federal or state law, appear to be intended to intimidate or coerce a civilian population, affect the conduct of a government by mass destruction, assassination or kidnapping, and is calculated to influence or affect the conduct of a government by intimidation or retaliate against government conduct. Terrorism is usually referenced as being premeditated and politically motivated. Terrorist acts are, by their very nature, designed and carried out with the intention of inflicting mass casualties and extensive property damage. When an act of terrorism is carried out in a jurisdiction, it will likely be necessary to implement multiple aspects of the emergency management system and summon additional resources from local, state, and federal partners. Terrorism is generally divided into two types: domestic terrorism and international terrorism. Domestic terrorism is defined as terroristic acts focused on facilities and populations without foreign direction. International terrorism involves activities that are foreign-based and/or sponsored by organizations outside of the United States. Terrorists often use threats to create fear among the public, to convince citizens that government is powerless to prevent terrorism and to get immediate publicity for their causes. Weapons of Mass Destruction (WMDs), including incendiary, explosive, chemical, biological, radiological and nuclear agents, have the capability to cause death or serious bodily injury to a significant number of people, thus posing the threat of a catastrophic incident. Terrorism can also include arson, agro- terrorism, armed attack, intentional hazardous materials release, water or food contamination, and attacks on infrastructure and electronic information systems. Hazard Profile Terrorism targets have historically been facilities that make a large economic or social impact on the targeted government or jurisdiction. In Walton County, all critical facilities could be seen as potential targets. Terrorism includes a multitude of potential approaches, including agro-terrorism, which is terrorism targeted toward agriculture. Due to the high economic impact (over $25 million in annual agriculture-related sales) of agriculture in Walton County, agro-terrorism could be of particular concern. ---PAGE BREAK--- 155 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Terrorism While active shooter situations are not always classified as terrorism, for this plan, the Walton County HMPC has chosen to classify them as such. Active shooter situations can occur in any location, including businesses, schools, government buildings, and public spaces. Schools are seen as particularly vulnerable to these types of situations due to the high publicity of recent active shooter events. While active shooter events and other acts of terrorism occur worldwide, they have low probability for Walton County but would have devastating impacts if they were to occur. To help mitigate some of these impacts, Walton County has exercised an active shooter response in the past to better prepare for any such event. Civil unrest is another particular act that is of concern to the Walton County Hazard Mitigation Planning Committee. While not generally associated with terrorism, this hazard is encompassed here due to the high economic and social impact civil unrest could have on Walton County. Assets Exposed to the Hazard Due to the unpredictable nature of terrorism, all public and private structures are threatened by the terrorism hazard. This includes all critical facilities. Estimated Potential Losses Losses due to terrorism are difficult to estimate due to the unpredictable nature of terrorism. The type of terrorist act carried out, location of the act, and the impact of the act would all affect the potential losses. Please see the critical facilities information for estimated potential losses for each critical facility. Land Use and Development Trends Walton County currently has no land use trends related to Terrorism. Multi-Jurisdictional Considerations All of Walton County, including all municipalities, are vulnerable to potential acts of terrorism. However, critical facilities and their surrounding areas are considered to be at the greatest risk. Hazard Summary Terrorism, while a low-probability hazard, would have devastating effects on Walton County and all municipalities. These impacts would be immediate and long-lasting and could be potentially economically crippling. ---PAGE BREAK--- 156 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Critical Infrastructure Failure Hazard Description Infrastructures, such as utilities and communication infrastructures, are particularly vulnerable to both natural and manmade hazards. While a communications or utility failure would most likely be a secondary hazard of one of the other hazards identified in this plan, an infrastructure failure could be a solo incident itself. A lack of communication with outside sources or a long-duration lack of utility service could lead to public panic, poor emergency response capabilities, and other domino hazards. These events pose a significant threat to many jurisdictions. Hazard Profile In case of any failure of a utility or communication infrastructure, general difficulties would be exacerbated for both emergency responders and for the general public. The reliance on wireless communications, particularly for the public safety sector, increases the vulnerability of Walton County’s emergency response agencies to a utility failure. Assets Exposed to Hazard All assets and critical facilities within Walton County could potentially be impacted by an infrastructure failure or could be the source for the infrastructure failure. Estimated Potential Losses Estimated potential losses cannot be anticipated with this event due to the vast number of differing scenarios regarding infrastructure failures. Land Use and Development Trends Walton County currently has no land use trends related to infrastructure failures beyond continued population growth. Multi-Jurisdictional Considerations Walton County as well as all municipalities could potentially be impacted by an infrastructure failure. However, the Cities of Loganville and Monroe are particularly vulnerable due to population density and higher reliability on technology. Hazard Summary The Walton County HMPC has determined that infrastructure failures pose a high risk to their jurisdictions due to the unpredictable nature of the incident. As a result, the Walton County HMPC has developed mitigation strategies and actions. ---PAGE BREAK--- 157 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Emerging Infectious Disease Hazard Description Microorganisms, such as bacteria, viruses, parasites, fungi, or prions, surround us within the environment. They can even be found within our own bodies. Most microorganisms are completely harmless, and many are actually beneficial. However, some of these organisms are pathogenic, meaning they cause or can cause disease. Infectious diseases are caused by these pathogenic organisms and are communicable – meaning they can be spread from person to person either directly or indirectly. Direct transmission of the disease occurs through actual physical contact with an infected person or their bodily fluids. Indirect transmission of a disease occurs when an infected person contaminates a surface by sneezing, coughing, etc., and a non-infected person comes into contact with that infected surface. Another means of indirect transmission includes vectors, such as mosquitos, flies, mites, ticks, fleas, rodents, or dogs, which may carry the pathogenic microorganism and transmit it to people via a bite. Infectious diseases can also impact animal populations, particularly livestock and other farm animals. Even though these diseases may not directly affect humans, the economic impact of these diseases can be just as harmful, if not more so, to the community. Infectious diseases can occur as primary events or they may occur as a cascading result of another disaster, such as a tornado, flood, or winter weather. Infectious diseases can vary greatly in severity and magnitude. According to the World Health Organization, infectious diseases account for three of the ten leading causes of death worldwide – HIV/AIDS, lower respiratory infections, and diarrheal disease. These three events, combined with tuberculosis and malaria, account for 20% of deaths globally. In Western countries, the impact of infectious diseases has diminished greatly over the last 75 years due to improved sanitation, personal hygiene, vaccinations, and the use of antibiotics. In the United States, only two infectious diseases – seasonal influenza and pneumonia – rank in the top ten leading causes of death. Annually, there are 1,500 deaths in the United States from seasonal influenza and another 52,000 from pneumonia. Children and older adults are the greatest at risk for both. Emerging infectious diseases are those that are appearing in a population for the first time. Re-Emerging infectious diseases are those that may have previously existed in a population, but levels had dropped to the point where it was no longer considered a public health problem until levels once again began increasing. ---PAGE BREAK--- 158 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Emerging Infectious Disease During the last 25 years, Emerging and re-emerging infectious diseases have been on the rise. The below table outlines some of the contributing factors to this rise: Contributing Factors to Increasing Occurrence of Emerging Diseases Agent-Related Factors • Evolution of pathogenic infectious agents • Development of resistance to drugs • Resistance of disease carriers to pesticides Host-Related Factors • Human demographic changes (humans inhabiting new areas) • Human behavior (sexual practices and drug use) • Human susceptibility to infection Environment-Related Factors • Economic development and land use patterns • International travel and commerce • Deterioration of surveillance systems Due to a lack of ready-made vaccines for these diseases and a lack of immunity in the population, emerging and re-emerging infectious diseases are much more likely to escalate to pandemic levels rapidly. CDC-Identified Emerging and Re-Emerging Infectious Diseases Drug-resistant Infections Mad Cow/Variant Creutzfeldt-Jakob Diseases Campylobacteriosis Chagas Disease Cholera Cyclosporiasis Cysticercosis Dengue Fever Diphtheria Ebola Hemorrhagic Fever Group B Streptococcal Infection Hantavirus Pulmonary Hepatitis C Hendra Virus Infection Histoplasmosis HIV/AIDS Influenza Lassa Fever Legionnaires’’ Disease and Pontiac Fever Leptospirosis Listeriosis Lyme Disease Malaria Marburg Hemorrhagic Fever Measles Meningitis Monkeypox MRSA Nipah Virus Infection Norovirus Infection Pertussis Plague Polio Rabies Rift Valley Fever Rotavirus Infection Salmonellosis SARS Shigellosis Smallpox Sleeping Sickness (Trypanosomiasis) Tuberculosis Tularemia Valley Fever (Coccidioidomycosis) VISA/VRSA Staphylococcus Aureus West Nile Virus Infection Yellow Fever ---PAGE BREAK--- 159 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Emerging Infectious Disease Hazard Profile Emerging Infectious diseases are of significant concern to the Walton County HMPC, particularly those that would have an impact on the human population or animal population of Walton County. Walton County would likely see significant economic impacts from an outbreak involving animal populations, such as an Avian Flu, due to the large economic base agriculture provides (over $25 million in annual sales). The lack of current vaccines and preparatory activities for these diseases has created a situation where the potential impact to Walton County of a pandemic or epidemic could be catastrophic. The most recent pandemic scare in the Central Georgia area was the 2009-2010 H1N1 Swine Flu. There were 1,286 cases of H1N1 in Georgia in 2009-2010 and 33 deaths. The majority of registered cases occurred with people between the ages of 5 and 29. This equates to a mortality rate of just over 2.5% - which is lower than the 3% rate of the 1918-1919 Spanish Flu Pandemic. In 2020, the COVID-19 Pandemic, caused by the SARS- CoV2 Virus, impacted communities worldwide, including Walton County. As of June 23, 2020, there were over 9.1 million cases reported worldwide with over 470,000 deaths. In Walton County, 346 cases had been reported with 25 deaths. Over the last 25 years, emerging infectious disease outbreaks have occurred in other parts of the country. These include: • 1993 Outbreak (Milwaukee, Wisconsin – 403,000 people ill and 100 deaths) • 2010 Whooping Cough Outbreak (California – 9,500 people ill and 10 infant deaths) • 2014 Measles (Nationwide – 334 cases from January to May 2014 – most in 20 years) • 2015 H5N2 Avian Flu Outbreak (Midwest – over 25 million chickens and turkeys destroyed as a precautionary measure at 83 locations) Assets Exposed to the Hazard Due to the unpredictable nature of emerging infectious diseases, all public and private structures are threatened by the hazard. This includes all critical facilities. Additionally, Walton County has over $25 million in annual agricultural sales, which could see significant impacts from any agriculture-related Emerging Infectious Diseases. Estimated Potential Losses Losses due to emerging infectious diseases are difficult to estimate due to the unpredictable nature of the hazard. The type of emerging infectious disease, location of the outbreak, and the impact of the outbreak would all affect the ---PAGE BREAK--- 160 I Page Walton County Hazard Mitigation Plan Update 2020 Technological Hazard: Emerging Infectious Disease potential losses. Please see the critical facilities information for estimated potential losses for each critical facility. Land Use and Development Trends Walton County currently has no land use trends directly related to emerging infectious diseases. Multi-Jurisdictional Considerations All of Walton County, including all municipalities, are vulnerable to emerging infectious diseases. However, livestock and other farm animals are considered to be the greatest at risk, along with areas with large, concentrated human populations, such as schools. Hazard Summary An emerging infectious disease would have devastating effects on Walton County and all municipalities. These impacts would be immediate and long-lasting and could be potentially economically crippling. Of particular concern to the Walton County HMPC is impacts to Walton County’s large agricultural business population (over $25 million in annual sales). Because of these considerations, the Walton County HMPC has developed mitigation actions with emerging infectious diseases in mind. ---PAGE BREAK--- 161 I Page Walton County Hazard Mitigation Plan Update 2020 Chapter Four - hazard mitigation strategies ---PAGE BREAK--- 162 I Page Walton County Hazard Mitigation Plan Update 2020 Summary of Updates to Chapter Four The following table provides a description of each section of this chapter, and a summary of the changes that have been made to the Walton County Hazard Mitigation Plan 2015. Chapter 4 Section Updates Goals and Objectives • Updated goals to match the needs of Walton County and all municipalities Identification and Analysis of Mitigation Techniques • Content Revised • Reviewed mitigation strategies identified in the 2015 plan and made updates • Identified mitigation strategies that were completed • Identified mitigation strategies to be removed ---PAGE BREAK--- 163 I Page Walton County Hazard Mitigation Plan Update 2020 Goals and Objectives Requirement §201.6(c)(3) Requirement §201.6(c)(3)(i) It is important that State and local government, public-private partnerships, and the average citizen can see the results of these mitigation efforts, therefore, the goals and strategies need to be achievable. The mitigation goals and objectives form the basis for the development of specific mitigation actions. County and municipal officials should consider the listed goals before making community policies, public investment programs, economic development programs, or community development decisions for their communities. The goals of Walton County have changed in the last five years (since 2015) due to specific threat events, such as Hurricane Irma in 2017. Because of the recentness of the impacts of these hazards and the devastation that occurred, these types of events have taken a greater priority, particularly in the increased priority of mitigation strategies directly related to these events and the development of new mitigation strategies related to these hazards. Each jurisdiction covered by the Walton County Hazard Mitigation plan update – Walton County and the Municipalities of Between, Good Hope, Jersey, Loganville, Monroe, Social Circle, and Walnut Grove – has limited ability to fully implement the mitigation actions described in this plan. These jurisdictions are severely hampered by their small population and tax base when attempting to raise enough revenue to pursue many of these actions. All jurisdictions lack the needed financial strength and staffing to implement all the actions described in this plan. Many of the actions will be pursued through grant programs and by partnering with public and private organizations who can supplement the needed resources to accomplish the goals outlined in this plan. For actions where grant funding or partnerships are not available, Walton County or municipality revenue streams may be supplemented through Special Purpose Local Option Sales Tax (SPLOST) funds, which are voted on by the electorate. GOAL 1 Maximize the use of all resources by promoting intergovernmental coordination and partnerships in the public and private sectors GOAL 2 Harden communities against the impacts of disasters through the development of new mitigation strategies and strict enforcement of current regulations that have proven effective GOAL 3 Reduce and, where possible, eliminate repetitive damage, loss of life and property from disasters GOAL 4 Bring greater awareness throughout the community about potential hazards and the need for community preparedness ---PAGE BREAK--- 164 I Page Walton County Hazard Mitigation Plan Update 2020 These objectives state a more specific outcome that Walton County strives to accomplish over the next five years. Action steps are the specific steps necessary to achieve these objectives. Objectives are not listed in order of importance. OBJECTIVE 1 Reduce damage to property and loss of life through the utilization of preventative activities OBJECTIVE 2 Minimize the damage to property and loss of life through property protection measures OBJECTIVE 3 Minimize the damage to property and loss of life through natural resource protection activities OBJECTIVE 4 Reduce damage to property and loss of life through the utilization of structural mitigation projects OBJECTIVE 5 Increase the ability of Walton County, its municipalities, and its citizens to respond to natural and manmade hazards through emergency service measures OBJECTIVE 6 Increase public education and awareness of natural hazards OBJECTIVE 7 Implement additional protective measures and capabilities in response to manmade incidents OBJECTIVE 8 Increase public awareness of local manmade hazards and proper response to those hazards ---PAGE BREAK--- 165 I Page Walton County Hazard Mitigation Plan Update 2020 Identification and Analysis of Mitigation Techniques Requirement §201.6(c)(3)(iv) Requirement §201.6(c)(3)(iii) In updating Walton County’s mitigation strategy, a wide range of activities were considered to help achieve the mitigation goals and objectives. This includes the following activities as by the Emergency Management Accreditation Program (EMAP): 1) The use of applicable building construction standards; 2) Hazard avoidance through appropriate land-use practices; 3) Relocation, retrofitting, or removal of structures at risk; 4) Removal or elimination of the hazard; 5) Reduction or limitation of the amount or size of the hazard; 6) Segregation of the hazard from that which is to be protected; 7) Modification of the basic characteristics of the hazard; 8) Control of the rate of release of the hazard; 9) Provision of protective systems or equipment for both cyber and/or physical risks; 10) Establishment of hazard warning and communication procedures; and 11) Redundancy or duplication of essential personnel, critical systems, equipment, and information materials. Part of the prioritization includes a general assessment according to the STAPLEE criteria, which stands for Social, Technical, Administrative, Political, Legal, Economic and Environmental. This process led to three designated priorities: High, Medium, and Low. Most items that require grant funding must undergo a full Benefit Cost Analysis to determine the action’s actual cost effectiveness prior to funding. This process will be completed as part of the grant opportunity application process. ---PAGE BREAK--- 166 I Page Walton County Hazard Mitigation Plan Update 2020 Strategy Priority Priority Description Strategies within this priority LOW Low priority strategies are those strategies that will have less direct impact on mitigating Walton County’s hazards, are in the early stages of strategy development, or score poorly on a preliminary cost-benefit analysis 2.g; 5.m; 5.n; 5.s; 5.v; 5.w; 5.bb; 5.ll; 5.pp; 5.qq; 6.b; 7.a MEDIUM Medium priority strategies are those strategies that will have a direct impact on mitigation Walton County’s hazards, but will not have as large of an anticipated impact as High Priority strategies or may be focused on hazards that are not as potentially impactful or prevalent for Walton County.

Prioritization was determined based on many factors. These include the likelihood of the event, the potential impact of the event, the current readiness posture of Walton County for the event, the all-hazard impact of the mitigation strategy, and a cost-benefit analysis for the mitigation action. For example, mitigation actions that address high-likelihood, high-impact events with a low cost would rate higher than low-likelihood, high-impact events with a high cost.

Plan maintenance protocols identified during the 2016 Walton County Hazard Mitigation Plan was followed, to the best abilities of Walton County. This most importantly included an increased attempt for public participation and inclusion in the planning process. The Walton County Hazard Mitigation Plan Update Committee will reconvene annually in February to monitor and evaluate the progress of the mitigation strategies in the Plan. Walton County’s Emergency Management Director, Carl Morrow, will be responsible for implementing this meeting. The Committee will discuss the following questions annually: - Do the goals address current and expected hazards and conditions? - Are the goals and objectives still relevant to the County? - Has the nature or magnitude of risks changed? - Does the risk assessment portion of the Plan need to be updated or modified? - Are the goals and objectives meeting changes in state and federal policy? - Are the current resources appropriate for implementing the Plan? - Are there local implementation problems, such as technical, political, legal, or coordination issues with other agencies? - Did the jurisdictions, agencies, and other partners participate in the plan implementation process as proposed? The responsible parties for various mitigation strategies will provide a report during this annual meeting regarding the following: - How well did the implementation processes work? - Were any difficulties encountered during implementation? - Are there any suggestions for revision of any strategies? Walton County’s Emergency Management Director will send the minutes from this annual meeting to Walton County Board of Commissioners and the municipalities of Between, Good Hope, Jersey, Loganville, Monroe, Social Circle, and Walnut Grove for review. If there are any updates or modifications to the Walton County Hazard Mitigation Plan, the Emergency Management Director will forward the changes to the Georgia Emergency Management Agency’s Hazard Mitigation Officer. All annual reviews of the Walton County Hazard Mitigation Plan will be open to the public. These meetings will be advertised both in the local newspapers, but also on signage in the publicly used facility hosting the meeting. ---PAGE BREAK--- 192 I Page Walton County Hazard Mitigation Plan Update 2020 Maintenance Log Revision Date Revised Section Reason for Revision Revised By 2019-2020 Five Year Hazard Mitigation Plan Update FEMA Requirement Walton County Hazard Mitigation Planning Committee with assistance from Lux Mitigation and Planning ---PAGE BREAK--- 193 I Page Walton County Hazard Mitigation Plan Update 2020 Plan Distribution This Plan will be distributed, but not limited, to the following departments and organizations within Walton County: Walton County Board of Commissioners Walton County Fire Department Walton County Emergency Management Agency Walton County Sheriff’s Office Walton County Public Works Walton County Planning and Zoning Walton County Code Enforcement Walton County Board of Education City of Loganville City of Monroe City of Social Circle Town of Between Town of Good Hope Town of Jersey Town of Walnut Gove A printed copy of the approved Plan will be available for viewing at the Walton County Commissioner’s Office located at 303 South Hammond Drive, Suite 330 in Monroe. A printed copy of the approved Plan will also be available for viewing at the Monroe-Walton County Library located at 217 West Spring Street in Monroe. The existence and location of these copies will be publicized in the County’s local newspaper, The Walton Tribune. All comments, questions, concerns, and opinions about the Plan will be directed to Director Carl Morrow of the Walton County Emergency Management Agency for follow-up. ---PAGE BREAK--- 194 I Page Walton County Hazard Mitigation Plan Update 2020 Implementation Requirement §201.6(c)(4)(ii) Each jurisdiction participating in the Walton County Hazard Mitigation Plan is responsible for implementing specific mitigation actions as prescribed in this plan. In the Mitigation Strategies section, every proposed strategy is assigned to a specific local department or agency to assign responsibility and accountability and increase the likelihood of subsequent implementation. In addition to the designation of a local lead department or agency, some strategies have secondary or assisting department or agencies listed as well. This allows for a sharing of responsibility and coordination of effort for some of the identified strategies that cross lines of departmental responsibility. The completion date has been assigned to assess whether identified mitigation strategies are being implemented in a timely fashion. Walton County and all municipalities will seek outside funding sources to implement mitigation projects in both the pre-disaster and post-disaster environments. When applicable, potential funding sources have been identified and targeted for the proposed actions listed in the mitigation strategies. It will be the responsibility of each participating jurisdiction to determine additional implementation procedures beyond those listed within the Walton County Hazard Mitigation Plan. This plan, as a joint effort between Walton County and the Municipalities of Between, Good Hope, Jersey, Loganville, Monroe, Social Circle, and Walnut Grove will serve as a comprehensive mitigation plan. The mitigation strategies, hazard identification, and other information identified in this plan will be integrated into all comprehensive Walton County plans, as well as all municipality plans in the future. Incorporation of these strategies will occur, as necessary, throughout this planning cycle covered by this Hazard Mitigation Plan Update. Aspects of this plan will be integrated into the Walton County Comprehensive Plan during the next planning cycle. Identified hazards and mitigation strategies of the 2015 Walton County Hazard Mitigation plan were integrated into the Local Emergency Operations Plan, multiple County and City SOPs and SOGs, and future planning and zoning plans. Walton County will integrate mitigation strategies identified in this plan into the Walton County Comprehensive Plan, Community Wildfire Protection Plan, Continuity of Operations Plan, and other future plans. Strategies identified in the previous plan were applied to grant applications, building and zoning requirements, and development planning considerations for Walton County and all municipalities. ---PAGE BREAK--- 195 I Page Walton County Hazard Mitigation Plan Update 2020 Many of these strategies will be applied using previously identified policies and ordinances, including the NFIP compliance ordinances and water-use ordinances, which have now been applied countywide. All jurisdictions have the authority to adopt locally binding ordinances and policies to enhance the mitigation strategies in their jurisdiction. The Legal and Regulatory Capability survey documents authorities available to the jurisdiction and/or enabling legislation at the state level affecting planning and land management tools that support local hazard mitigation planning efforts. The identified planning and land management tools are typically used by states and local jurisdictions to implement hazard mitigation activities. Opportunities to integrate the requirements of this Plan into other local planning mechanisms shall continue to be identified. Some mitigation strategies may be included in the Walton County Joint Comprehensive Plan, the Walton County Community Wildfire Protection Plan, and will be considered during future land use and capital improvement planning initiatives. All municipalities participate as part of the Walton County Joint Comprehensive Plan. Although it is recognized that there are many possible benefits to integrating components of this Plan into other local planning mechanisms, the development and maintenance of this stand-alone Hazard Mitigation Plan is deemed by the Walton County Hazard Mitigation Planning Committee to be the most effective and appropriate method to implement local hazard mitigation actions at this time.

These revisions should also consider any potential changes in the hazard vulnerability and mitigation priorities of Walton County. The Walton County Hazard Mitigation Plan Update Committee will meet annually to review the Walton County Hazard Mitigation Plan. During this annual review, mitigation strategies will be reviewed to evaluate the progress that has occurred for each identified mitigation strategy. The Walton County Hazard Mitigation Plan Update Committee will also meet following any disaster event to review the identified mitigation strategies for that hazard and determine if timelines should be adjusted or additional mitigation strategies should be identified and added to the plan. These steps will ensure that the Walton County Hazard Mitigation Plan is continuously updated to allow for changes in hazard vulnerabilities and identified mitigation strategies. The Walton County Hazard Mitigation Plan Update Committee will complete all evaluations of the Walton County Hazard Mitigation Plan. ---PAGE BREAK--- 198 I Page Walton County Hazard Mitigation Plan Update 2020 Peer Review State Requirement Element F1 To maintain standards of quality, improve performance, and provide credibility to the Walton County Hazard Mitigation Plan Update, representatives of local emergency management agencies bordering Walton County conducted a peer review of the Plan. The peer review of this Plan constitutes a form of self- regulation, accountability, and new insights offered by qualified professionals in neighboring communities, which face many of the same natural and man-made hazards. Walton County Hazard Mitigation Plan Update was peer reviewed by: Greg Swanson Date Director Gwinnett County Office of Emergency Management Jody Nolan Date Director Newton County Emergency Management Agency Gwen Ruark Date Director Morgan County Emergency Management Agency Penny Clack Date Director Barrow County Emergency Management Agency ---PAGE BREAK--- 199 I Page Walton County Hazard Mitigation Plan Update 2020 Plan Update Requirement §201.6(c)(4)(i) The Federal Disaster Mitigation Act of 2000 requires that the Hazard Mitigation Plan be updated at least once every five years. The Walton County Emergency Management Agency is the department responsible with ensuring this requirement is met. The Walton County Hazard Mitigation Plan Update Committee will be involved in this future process and will aid the Walton County Emergency Management Agency in ensuring that all jurisdictions provide input into the planning process. The public will be invited to participate in the planning process through public hearings to be held whenever major updates to this plan are needed and during annual review meetings. This plan will expire in the fourth quarter of 2025; therefore, the approval and adoption of the next plan update must be completed before that time. In the first quarter of 2023, Walton County plans to begin the Hazard Mitigation Plan Update process for the fourth time. This planning process will include bi- meetings to accomplish the identified goals of the Walton County Hazard Mitigation Plan Update. This process will be headed up by the Walton County Emergency Management Agency. The Walton County Hazard Mitigation Planning Committee will follow a similar process as was undertaken during this planning cycle to complete all FEMA and GEMA requirements for the Hazard Mitigation Plan Update. This process will be completed by the third quarter of 2024 to meet all identified planning deadlines. ---PAGE BREAK--- 200 I Page Walton County Hazard Mitigation Plan Update 2020 Conclusion As a result of the hazard mitigation planning process, Walton County, and all municipalities therein, as well as additional participating organizations have obtained a great deal of information and knowledge regarding Walton County’s disaster history, natural and technological hazards, vulnerabilities, and potential strategies to lessen the impacts of the identified hazards. One consistent theme identified by the Walton County Hazard Mitigation Planning Committee was the inability to consistently identify geographic locations that were more vulnerable to most hazards due to the widespread potential effects and random impact areas each hazard could have. This was exceedingly true for most natural hazards. Recognizing this challenge, the Walton County Hazard Mitigation Plan Update Committee determined it was best to identify many mitigation goals, objectives, and strategies that were both general and specific in nature. These strategies allow the Walton County Hazard Mitigation Plan Update Committee to adopt strategies that will have the greatest positive effect on the greatest amount of the population. ---PAGE BREAK--- 201 I Page Walton County Hazard Mitigation Plan Update 2020 Appendix A – Walton County Dams Information Category I Dams Name Latitude Longitude Height (feet) Storage (acres) Buccaneer Lake Dam 33.817910 -83.716260 38.00 1300.00 Hard Labor Creek Reservoir Dam 33.681667 -83.632222 97.00 76420.00 Jt Briscoe Reservoir Dam 33.830000 -83.767222 32.00 3036.00 Category II Dams Name Latitude Longitude Height (feet) Storage (acres) Adcock Dam 33.700556 -83.680000 35.00 187.00 Arnold Dam 33.706667 -83.740000 24.00 126.00 Aycock Lake Dam 33.813611 -83.689444 25.00 68.00 Big Bass Lake Dam 33.817778 -83.718611 24.00 201.00 Bradley Dam 33.638333 -83.665833 18.00 115.00 Bruce Lake Dam 33.854444 -83.757222 30.00 182.00 Calhoun Dam 33.731944 -83.858333 28.00 99.00 Camp Dam 33.772222 -83.769444 20.00 77.00 Lake Dam Lower 33.700556 -83.680000 29.00 65.00 Lake Dam Upper 33.700556 -83.680000 44.00 120.00 Emerald Cove Lake Dam 33.749167 -83.859444 28.00 94.00 Fairweather Farms Irrigation Lake Dam 33.720556 -83.681944 36.00 295.00 Henderson Dam 33.765833 -83.920000 28.00 102.00 Hickman Dam 33.769444 -83.909722 23.00 121.00 Kelly Lake Dam (Lower) 33.736111 -83.729722 14.00 82.00 Lake Monroe Dam 33.800833 -83.769722 22.00 174.00 McGarity Dam 33.691667 -83.720833 28.00 131.00 Monroe Mountain Creek Oxidation Pond 33.766667 -83.069444 15.00 275.00 Porterfield Lake Dam 33.781111 -83.638611 31.00 90.00 Proposed Danielly Lake Dam 33.748333 -83.912500 37.00 270.00 Rainbow Lake Dam 33.778056 -83.791111 26.00 99.00 Roberts Irrigation Lake Dam 33.750000 -83.783333 24.00 840.00 Shephard Dam 33.693611 -83.818611 31.00 160.00 Trucker Farm Pond 33.810278 -83.832194 19.00 132.00 Wellman Lake Dam 33.727222 -82.738889 26.00 225.00 West Lake Dam 33.789444 -83.906944 38.00 120.00 Whitley Dam 33.688889 -83.758611 21.00 107.00 Williams Lake Dam 33.721389 -83.723611 38.00 248.00 Wood Lake Dam 33.699167 -83.642500 50.00 460.00 ---PAGE BREAK--- 202 I Page Walton County Hazard Mitigation Plan Update 2020 Appendix B – Walton County Hazard Mitigation Planning Committee Sign-In Sheets ---PAGE BREAK--- 203 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 204 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 205 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 206 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 207 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 208 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 209 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 210 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 211 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 212 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 213 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 214 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 215 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 216 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 217 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 218 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 219 I Page Walton County Hazard Mitigation Plan Update 2020 ---PAGE BREAK--- 220 I Page Walton County Hazard Mitigation Plan Update 2020 Appendix C – Walton County Critical Facilities Name Jurisdiction Facility Types Jersey Christian Academy Jersey town NGO, Private Grand Haven Good Hope town Medical, ALF Good Hope City Hall Good Hope town Government, Government Offices George Walton Academy Walton County NGO, Private GA Forestry Commission -
