Comprehensive Figures Appendix C: Barnstable Town Council Resolution Town of Barnstable (233963.00) 1-1 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 1. THE PLANNING PROCESS The Town of Barnstable (the “Town” or “Barnstable”), located in Barnstable County, Massachusetts, has developed this Hazard Mitigation Plan (HMP) update to identify and profile the town’s risk and vulnerability to potential natural hazards and to build upon the resiliency efforts first outlined in its 2010 HMP. Specifically, this update assesses the potential impacts of shoreline change/coastal erosion, hurricanes, dam failure, earthquakes, drought/wildfire, flooding, winter storms, tornadoes, and tsunami and identifies properties, resources, and critical facilities which may be impacted by these hazard events. The update identifies mitigation strategies and actions aimed at reducing the loss of or damage to life, property, infrastructure and natural, cultural, and economic resources. A corresponding implementation plan has been prepared to address the prioritization and administration of the identified strategies and actions. Lastly, the update includes a schedule for monitoring, evaluating, and further updating the plan in the future. This plan was prepared in compliance with the Robert T. Stafford Disaster Relief and Emergency Assistance Act, the Disaster Mitigation Act of 2000, and 44 CFR §201.6. Furthermore, this plan was developed in collaboration with the Cape Cod Commission (CCC), the Cape’s regional land use planning and regulatory agency. 1.1 PURPOSE OF THE PLAN Hazard mitigation is defined as any sustained action to reduce and/or eliminate short or long-term risk to life and property from natural hazards. The purpose of this plan update is to lessen the impact of a disaster before it occurs and provide the following benefits to the Town of Barnstable: 1. Protect lives and reduce social, emotional, and economic disruption following a disaster event; 2. Prevent the loss of property, infrastructure, and natural and cultural resources from natural disasters; 3. Increase public awareness of risk and vulnerability to natural disasters; 4. Increase access to funding sources for hazard mitigation projects; and 5. Improve the ability to implement post-disaster recovery projects. These disaster mitigation goals are an effort to reduce or avoid both short and long-term vulnerabilities to the identified hazards. The objectives of the proposed mitigation strategies will include a section that identifies specific mitigation actions and analysis to reduce the effects of each hazard with particular attention on new and existing buildings and structures. 1.2 THE PLANNING TEAM The hazard mitigation planning team consisted of representatives from a comprehensive range of Town Departments and local agencies dealing with issues related to hazard mitigation and risk assessment. The team was comprised of the following members that either attended the HMP update workshop at Town Hall or participated via separate virtual meeting session with Woodard & Curran and the Planning Staff for the Town of Barnstable: Workshop Attendees: Elizabeth Jenkins, AICP, Director of Planning & Development Kate Maldonado, Assistant Director Planning & Development James Kupfer, AICP, MPA, Senior Planner, Planning & Development Derek Lawson, Marine and Environmental Affairs Director Brian Taylor, Harbor Master, Marine and Environmental Affairs Peter Burke, Hyannis Fire Chief Town of Barnstable (233963.00) 1-2 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 David Wedd, Hyannis Fire Department Megan Savage, Safety Officer Gordon Starr, Town Council Mary House and Matthew Jones, Woodard & Curran Joe Maruca, West Barnstable Fire Chief Amber Unruh, Senior Project Manager, DPW Nathan Collins, Assistant Town Engineer, DPW Darcy Karle, Conservation Administrator Jeff Carter, Deputy Director, Inspectional Services Nina Z Coleman, Natural Resources Director/Sandy Neck Park Manager Virtual Meeting Attendees: Shannon Hulst, Deputy Director; Floodplain Specialist & CRS Coordinator, Cape Cod Cooperative Extension & Woods Hole Sea Grant Greg Berman, Coastal Processes Specialist, Cape Cod Cooperative Extension & Woods Hole Sea Grant Heather McElroy, Natural Resources Specialist, Cape Cod Commission Chloe Schaefer, Chief Planner, Cape Cod Commission Martha Hevenor, Planner, Cape Cod Commission 1.3 THE PLANNING PROCESS The Town’s Planning & Development Department oversaw the development of this HMP plan update. The Planning & Development project lead, James Kupfer, identified the HMP update team and convened the team at a half day workshop on November 8, 2021, to review the 2010 HMP and evaluate hazards, risks, and vulnerabilities and recommend and prioritize mitigation actions. An HMP team was originally assembled in 2004, in conjunction with the Cape Cod Commission’s initiative to develop a multi-jurisdictional multi-hazard mitigation plan in compliance with the Disaster Management Act of 2000. The Town of Barnstable Planning Department (GMD) completed a considerable amount of work on a local HMP plan during 2004, but the plan was never locally adopted or submitted to FEMA for certification. The GMD resumed the HMP planning process in 2010 by reviewing and updating the original draft of the plan and reconvening the HMP team. The following provides a summary of the planning process. The HMP team first identified and reviewed the goals of the multi-hazard mitigation plan for the Town of Barnstable and reviewed the natural hazards that could potentially affect the Town. In the initial planning stages, the MHM team accomplished the following: A review of a history of past events, which are represented primarily by the Regional Hazard Risk Maps. An evaluation of the risk or frequency of each hazard occurring. An evaluation of the potential extent, or severity, of each identified hazard. A determination of the scope of potential damage that could be inflicted by each identified hazard. The HMP team reviewed the Town’s overall vulnerability to the hazards addressed in this plan and the Hazard Identification Matrix to ensure the scope and severity of potential disasters were accurately represented. The team reviewed the Risk and Vulnerability Assessment Map and Regional Hazard Risk Maps to ensure they represented all specific geographic locations that are vulnerable for the identified hazards. An existing list of critical facilities was Town of Barnstable (233963.00) 1-3 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 reviewed, updated, and analyzed for this plan. The Town’s GIS department conducted an analysis of structures vulnerable to flooding. Finally, the Town’s participation in the National Flood Insurance Program was reviewed. Led by the Town’s Planning & Development department with outside support from Woodard & Curran, an update to the 2010 HMP was attempted and several of the plan’s components were completed in 2016, but the HMP was not finalized or submitted. At this time, a workshop was held with key stakeholders to obtain input on hazards, vulnerabilities and critical facilities and develop mitigation actions. Goals and objectives were revised to be more comprehensive and encompass the top hazards identified. In 2018, the Town received a grant from the Massachusetts Executive Office of Energy and Environmental Affairs Municipal Vulnerability Preparedness (MVP) Program to identify vulnerabilities from natural hazards and climate change and develop actions to mitigate the hazards. The Town of Barnstable contracted with staff from the Cape Cod Commission and Woods Hole Sea Grant & Cape Cod Cooperative Extension to guide the process to become an MVP certified community and engage community stakeholders through a community resilience building workshop held on March 29, 2019. The 2010 Hazard Mitigation Plan was relied upon greatly to support the MVP effort and was used to review critical facilities, past hazard events and impacts, and mitigation goals and actions. Subsequently, The Town published the findings from the community resilience building workshop and achieved its MVP designation. In 2021, the Town’s Planning & Development department contracted with Woodard & Curran to revisit the work completed in 2016 and to refresh and finalize an update to the 2010 HMP. The Town of Barnstable held a half day workshop with the planning team on November 8, 2021, to discuss the 2022 HMP update. At this meeting, the Town of Barnstable reviewed the components of previous hazard mitigation documents, discussed proposed revisions and project timelines, presented major hazard concerns, identified asset changes, reviewed recent emergency events and planned preventative actions, discussed repetitive losses, and determined mitigation projects to continue and introduce in the 2022 update. To close out the meeting, the Town of Barnstable discussed the next steps for public involvement, formal adoption, and submission to MEMA and FEMA. On November 19, 2021 and December 10, 2021 members of the Cape Cod Cooperative Extension and the Cape Cod Commission respectively, had a virtual meeting to provide input into the plan. Conversations focused on crucial mitigation project interests and implementation. 1.4 REGIONAL COOPERATION The Cape Cod Commission (CCC) led a regional effort to develop a multi-jurisdictional hazard mitigation plan for Barnstable County. The Barnstable County Natural Hazards Pre-Disaster Mitigation Plan (the Regional PDM plan) addresses natural hazards affecting all of Cape Cod. The Town of Barnstable has maintained continuing representation on the regional Multiple Hazard Community Planning Team. The regional team consists of representatives from all 15 Cape Cod communities and representatives from regional environmental, social, and emergency management groups. The CCC began the process to update the 2004 regional plan in June of 2009 and has provided ongoing technical support for the development of this plan, and other local plans. 1.5 PUBLIC PARTICIPATION This plan update was formulated and reviewed by the Town’s HMP Team, but also benefited from review by the general public. A Public review process is essential to the development of an inclusive and effective plan. A draft of the plan was made available for review on the Town website on February 22, 2022 and a public comment period was open through March 21, 2022. Town of Barnstable (233963.00) 1-4 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 The Town of Barnstable Site Plan Review Committee and Planning Board are the two primary local reviewing authorities responsible for regulating development in the town. The Site Plan Review Committee is an administrative committee made up of various town departments such as Building, Fire, Health, and Planning. All applicable departments sat on and played a vital role for the Hazard Mitigation Update Team. In addition, the Cape Cod Commission is a regional planning and review authority. The Commission played an important role in providing early review of the draft plan and provided important comments that were integrated in the final update. The draft plan was presented to the Town of Barnstable Planning Board at its March 14, 2022 regularly scheduled meeting of the Planning Board staff and the Town’s consultant, Woodard & Curran. The meeting was advertised, televised and open to the public for public comment. Planners from surrounding communities were invited by special invitation and included the Town of Yarmouth, Town of Sandwich and Town of Mashpee. The contents of the plan were reviewed with the Board at the meeting and the Planning Board provided feedback. Comments regarding the accessibility to future funding were addressed. Appendix A provides documentation on the public engagement process. 1.6 USES OF THE 2010 HAZARD MITIGATION PLAN The 2010 Hazard Mitigation Plan was used for multiple purposes in various Town planning initiatives. It has been referred to numerous times to guide emergency responses efforts and to examine potential impacts to critical facilities during hazard events. The Town has taken steps to implement the findings of the plan into the newly adopted Floodplain bylaws, the low-lying streets study, certification to become a Complete Streets certified community and to support the development of mitigation actions under the Municipal Vulnerability Preparedness Program.

GOALS AND OBJECTIVES This section outlines the goals and objectives identified by the Town of Barnstable to guide its philosophy and approach to creating a more resilient community. The goals were expanded significantly from the 2010 HMP to more directly address the top priority hazards faced by this coastal community. 2.1 HAZARD IDENTIFICATION According to FEMA guidance documentation, a goal serves as a general guideline that explains what a community would like to achieve and an objective defines a specific strategy or implementation step that will help reach a specific goal. The following goals and objectives in Table 2-1 are reflective of goals articulated in Barnstable’s previous hazard mitigation plans and include changes and updates based on stakeholder and staff input to guide the implementation of the 2022 Hazard Mitigation Plan. Table 2-1: Barnstable 2022 Hazard Mitigation Plan Goals Goal #Details Goal 1 Protect public safety and welfare during and following disaster events. Goal 2 Prevent or reduce the loss of property, infrastructure, and natural and cultural resources from natural disasters. Goal 3 Increase public awareness of risk and vulnerability to natural disasters. Goal 4 Increase access to funding sources for hazard mitigation projects. Goal 5 Improve the ability to implement post-disaster recovery projects. Barnstable reviewed the 2010 Mitigation Strategies and made some modifications including referring to them in this 2022 plan update as objectives to accompany and help achieve the identified goals. The strategy for the goals and objectives is to address the threat and impact of natural hazard events through preventative regulations, property and natural resource protection, structural improvements and increased public awareness. Mitigation Objectives were reviewed and revised for this 2022 Barnstable Hazard Mitigation Plan update, which are shown in Table 2-2. Table 2-2: Barnstable 2022 Hazard Mitigation Plan Objectives Objective #Details Objective 1 Preserve the natural and beneficial functions of the town’s floodplain, wetlands, beaches and dunes through continued support of natural resource protection. Objective 2 Limit development in high hazard and environmentally-sensitive areas to minimize loss of life and structures, reduce erosion and prevent other environmental damage resulting from natural hazards. Objective 3 Support the protection and restoration of barrier beaches and coastal banks to the greatest extent possible to protect important wildlife habitat from storm surge, preserve recreational amenities and enhance these natural features that provide flood protection. Objective 4 Reduce wildfire hazard within vulnerable open space lands and urban interface zones through integrated and proactive land management programs as well as education and outreach efforts. Objective 5 Adopt and/or amend (re)development regulations applicable to land, structures and wastewater systems in hazard-prone areas to ensure structures are designed to withstand potential events and to prevent the disturbance of natural areas.

NATURAL HAZARDS The Town of Barnstable has the potential to be impacted by a wide range of natural hazards and each one presents certain risks to life and property. Understanding what specific hazards have and may impact the community is required by FEMA regulations and guidance detailed in the Disaster Mitigation Act of 2000. This section identifies the natural hazards that have impacted Barnstable in the past and those that could affect the community in the future. 3.1 HAZARD IDENTIFICATION The term hazard in this plan is defined as an extreme natural event that poses a risk to people, infrastructure, property or resources. The natural hazards identified and included in this plan received their initial consideration from FEMA Guidance documentation. The hazards were then further researched by utilizing current and historical data points from various sources including but not limited to NOAA, US Census, FEMA Disaster Declarations and other regional/state planning documents, including the Massachusetts Hazard Mitigation Plan (2013). The Town of Barnstable reviewed the findings of each identified natural hazard and considered them against local knowledge to finalize the list of natural hazards that have impacted Barnstable in the past or could impact the community in the future. 3.1.1 Natural Hazards Impacting Barnstable Table 3-1 identifies hazards that may affect the Town of Barnstable, a profile of the associated risks, and a record of previous occurrences.

General descriptors to discuss the probability of these natural hazard events for the purposes of this planning effort include: Highly likely – Hazard event occurs every 1-10 years. Likely – Hazard event occurs every 10-50 years. Unlikely – Hazard event occurs infrequently and greater than every 50 years. Unknown – Insufficient data exists to make a more specific determination. In some instances, a natural hazard event is more likely to occur during a specific time of year such as a winter storm or hurricane and this additional information is included in the individual hazard profiles. 3.2 HAZARD PROFILES 3.2.1 Coastal Erosion/Shoreline Change In general, coastal erosion refers to the wearing away of land that may result in the removal of beaches, dunes or other shoreline vegetation by substantial wave action, tidal currents or drainage. Coastal erosion may result in long-term sediment, rock and sand loss or the redistribution of these features. In severe cases, the shoreline can be temporarily displaced landward and cause damage to personal property. Shoreline structures are a method of mitigation but while they may protect some structures and assets, they can also cause more damage in other areas as a result. Town of Barnstable (233963.00) 3-6 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 In Barnstable, the coastline is constantly changing, but long-term trends indicate that 73% of Barnstable’s shores are experiencing erosion and 25% are experiencing accretion. Shoreline change, specifically erosion, can result in a direct threat to waterfront property and indirectly impacts the developed environment by increasing vulnerability to storm damage and flooding. Erosion and accretion are important natural processes that mitigation actions must respect to protect the long-term health of Barnstable’s beaches and dunes. Shoreline change can result from both natural and human activity. Gradual sea-level rise and coastal storms are the primary natural causes of erosion. The extent of the erosion or accretion in a particular location is affected by several variables, including the site’s exposure to storms and waves and sediment size and transport rates. Human-induced shoreline change results from the interruption of sediment sources by armoring coastal bluffs and the interruption of longshore sediment transport by the construction of jetties and groins. 3.2.1.1 Hazard Location Coastal erosion and accretion rates along Barnstable’s coast are represented in Figure 1 in Appendix B. Areas most adversely impacted by erosion are found on Sandy Neck Beach and the north shore west of Barnstable Harbor where rates of erosion exceed two feet per year. On the south shore of Barnstable, areas with the most extreme erosion impacts are found in small areas west of Hyannis Point and along the west side of Long Beach in Centerville Harbor. Figure 1 and Figure 2 illustrate the historic shoreline change in Barnstable using data from the Massachusetts Ocean Resource Information System (MORIS). Figure 1: Historic Shoreline Change for Barnstable, MA (North Coast) Town of Barnstable (233963.00) 3-7 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 2: Historic Shoreline Change, Barnstable, MA (South Coast) 3.2.1.2 Previous Occurrences, Severity & Extent of the Hazard In Massachusetts, the shoreline is eroding and has been over a long period of time at a rate of approximately .56 feet per year1. A study of shoreline change in Massachusetts by the USGS survey, Woods Hole Oceanographic Institution Sea Grant Program, and Cape Cod Cooperative Extension reveals that approximately 68 percent, or 513 miles, of Massachusetts' ocean-facing shore exhibits a long-term erosion trend, 30 percent, or 226 miles, shows long-term accretion, and two percent, or 15 miles, shows no net change. In December 2015, the Report of the Massachusetts Coastal Erosion Commission Volume 1: Findings and Recommendations was released which is the work, findings, and recommendations of the Massachusetts Coastal Erosion Commission. The tasks of the Commission included making a reasonable assessment of coastal erosion and corresponding financial damage, making a reasonable estimate of damages to occur in the next 10 years under current conditions, evaluating current rules, regulations and laws governing shoreline management, and examining possible changes and cost-effective measures to improve the potential to reduce or eliminate impacts of coastal erosion. Shoreline change analysis was conducted for each community covered by the Shoreline Change Project and the results for Barnstable are included in Table 3-2. Table 3-2: Barnstable Average Shoreline Change Rates and Uncertainty Short Term Rate Long Term Rate Mean (ft/yr)Standard Dev (ft/yd) Mean (ft/yr)Standard Dev (ft/yr) Entire Town 0.4 5.2 -0.4 2.2 Cape Cod Bay 1.1 7.2 -0.2 2.3 Nantucket Sound -0.3 2.1 -0.7 2.0 1 Woods Hole Oceanographic Institute, “Shoreline Change and the Importance of Coastal Erosion,” [http://www.whoi.edu/seagrant/page.do?pid=51817&tid=282&cid=88713], 2021 Town of Barnstable (233963.00) 3-8 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Barnstable has experienced coastal erosion throughout the community due to its coastal location. Since 2013, the Town has taken emergency parking lot stabilization efforts by bringing in over 28,000 cubic yards of sediment in the Sandy Neck beach area. 3.2.1.3 Impact & Vulnerability The Town of Barnstable is vulnerable to coastal erosion in the future. Erosion is a natural process, however when it occurs near coastal property, infrastructure or natural resource areas, damage can occur. Coastal erosion in general does not necessarily have an immediate impact on life, property or operations. The impacts of this hazard are a result of repeated occurrences over time of coastal storms that can result in property loss or severe consequences that often require hard infrastructure solutions to protect the built environment. However, coastal erosion and shoreline change can cause significant economic loss due to destruction of buildings, roads, infrastructure, natural resources and habitat areas either through one storm event or through repetitive storm events over time. In 2018, the Town collaborated with the University of Massachusetts to identify landscape-based adaptations for sea level rise documented in “At the Water’s Edge” report. 3.2.1.4 Probability of Future Occurrence According to FEMA, there has never been a Presidential Disaster Declaration made for coastal erosion in the State of Massachusetts. The NCDC Storm Database does not keep record of erosion events, and the data in this section is anecdotal and research based. According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of a future coastal erosion in Barnstable is highly likely. High rates of coastal erosion occur most frequently along long sections of shoreline which are consistently subjected to high wave energy and coastal storms. The factors that determine whether or not a community or area may exhibit greater probability for long term coastal erosion include: Exposure to high-energy storms; Exposure to high-energy storm waves; Sediment size and composition of eroding coastal landforms adjacent to shorelines; Relative sea level rise, and Human interference with sediment supply (seawalls, jetties). 3.2.2 Hurricane Hurricanes are characterized by a sustained wind speed of 74 miles per hour or more, wind that blows in a large spiral motion around a rotating “eye” (calm center of the storm), and an expansive reach that can extend for hundreds of miles. Powerful in nature, hurricanes can be short in duration or last for several days impacting numerous states, counties and towns along the coastline. The aftermath of a hurricane frequently causes additional damage due to lasting high winds, storm surge, and flooding. Storms that have associated wind speeds between 39 mph and 73 mph are classified as tropical storms. The Atlantic hurricane season runs from June 1st through November 30th. Based on the number and intensity of storms, mid-August through mid-October is defined as the peak period. 3.2.2.1 Hazard Location Barnstable is susceptible to experiencing hurricane events. According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the entire state is susceptible to hurricanes and tropical storms, but the coastal areas are more susceptible due to the combination of high winds and surge. Figure 3 shows the historical hurricane tracks that have impacted Barnstable. A map showing Hurricane Inundation Zones is located in Appendix B. Town of Barnstable (233963.00) 3-9 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Since hurricane tracking began, there have been 10 direct hurricane hits to the Massachusetts coastline. The only other New England state to have as many direct hits was Connecticut. A “direct hit” means that the core of strong winds and/or storm surge was experienced. The Town of Barnstable, as a coastal community, is subject to flooding, storm surge, episodic erosion, tornadoes, and wind damage from hurricanes. Figure 3: Historical Hurricane Tracks Source: NOAA Office for Coastal Management 3.2.2.2 Previous Occurrences, Severity & Extent of the Hazard Since 1954, there have been six Major Disaster Declarations in the State of Massachusetts due to a hurricane or tropical storm and four of those have resulted in Barnstable County receiving a designated area status from FEMA (see Table 3-3). Historically, the Town of Barnstable has been directly impacted by at least 3 hurricanes and 1 Tropical Storm (Irene), the most recent storm to impact Barnstable was Hurricane Sandy in 2012.

Hurricane 22 9/2/1954 9/2/1954 Unknown There was heavy storm surge to Narragansett Bay and New Bedford Harbor. Source: FEMA Major Disaster Declarations 1954 – 2021 Some of the more notable hurricane events include: Hurricane Sandy (2012) – In the fall of 2012, Hurricane Sandy had a major impact on the New York and New Jersey coastline. The storm broke an all-time record for storm surge height in New York harbor, caused over 100 fatalities, and has reached a cost of over $79 billion for federal aid to cover damages, recovery and mitigation measures. In Massachusetts, Sandy knocked out power to over 200,000 customers, disrupted travel and closed schools. Downed trees, power lines and flooding were also present during and after the storm. Heavy coastal flooding impacted 3,662 properties in Barnstable County while high winds caused destruction and downed utilities. Hurricane Bob (1991) – This was a costly hurricane at approximately $1.5 billion and left extensive damage throughout New England. The loss of life and most of the damage occurred as a result of high winds and rough seas. There were six confirmed tornadoes during its passage. Power outages and a lack of running water were universal across Cape Cod, even at shelters. The Bourne and Sagamore Bridge were closed by officials, isolating the Cape from the mainland. Southern-facing shorelines experienced the most significant erosion, up to 50 feet in some places. Telephone lines were unreliable, if operable, and shelters across the Cape were overfilled with vacationers and boat residents, as well as those who lost their homes in the storm. Hurricane Gloria (1985) – A storm that hit Long Island, NY and New Jersey that caused minor storm surge, erosion damage and substantial wind damage. Gloria made landfall in the Outer Banks of North Carolina and was a fast-moving hurricane that struck at low tide, reducing storm surges and passing quickly before inflicting maximum wind damage to coastal communities. Its main track passed over eastern Massachusetts, sparing Cape Cod from any significant damage. For reference and tracking purposes, hurricanes are categorized by class in accordance with the Saffir-Simpson Hurricane Wind Scale (SSHWS) summarized in Table 3-4. The SSHWS uses a 1-minute sustained wind speed at a Town of Barnstable (233963.00) 3-11 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 height of 33 feet over open water as the sole parameter to categorize storm damage potential.2 A storm with organized circulation and sustained winds below a Category 1 Hurricane threshold (winds range from 39 to 73 mph) is categorized as a tropical storm. Table 3-4: Saffir-Simpson Hurricane Wind Scale (SSHWS) Category Wind Speed Storm Surge (feet above normal sea level) Expected Damage 1 74-95 mph 4-5 feet Minimal: Damage is done primarily to shrubbery and trees, unanchored mobile homes are damaged, some signs are damaged, damage to structures is minimal or none. 2 96-110 mph 6-8 feet Moderate: Some trees are toppled, some roof coverings are damaged, and mobile homes may have major damage. 3 111-130 mph 9-12 feet Extensive: Large trees are toppled, some structural roof damage occurs, mobile homes are destroyed, structural damage to small homes and utility buildings is possible. 4 131-155 mph 13-18 feet Extreme: Extensive damage is done to roofs, windows and doors; roof systems on small buildings completely fail; some curtain walls fail. 5 > 155 mph > 18 feet Catastrophic: Roof damage is considerable and widespread, window and door damage is severe, there are extensive glass failures, and entire buildings could fall. It is important to note that lower category storms, including tropical storms, can inflict greater damage than higher category storms depending on where and when the storm strikes. Tropical storms have been known to produce significant damage and loss of life, mainly due to flooding. 3.2.2.3 Impact & Vulnerability Barnstable is vulnerable to hurricanes due to its proximity to the coast. According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, impacts to the state in addition to a direct hit can include effects from tropical remnants such as heavy rain, localized flooding and storm surge. The greatest impacts from hurricanes to property and infrastructure include wind and water damage: flooding, utility failure, building damage, shoreline erosion, natural resource damage; interruptions with emergency, fire, and police services, and economic loss due to business property damage and loss of inventory. A hurricane can have devastating effects on a large area if directly in the path of a hurricane causing long term affects to the local economy and environment. One unique impact to Barnstable is that ferry service to Nantucket and Martha’s Vineyard operate from the Hyannis Terminal in the inner harbor. During a large-scale hurricane event which would require evacuating these communities, Barnstable would be impacted by a large influx of residents and visitors who may have to leave abruptly and require emergency shelter or other services. Barnstable serves as a lifeline to these two island communities. There is a general concern about the damage that would occur in the inner harbor during a substantial hurricane. The potential impacts 2 FEMA Coastal Construction Manual, 2011 Town of Barnstable (233963.00) 3-12 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 to the hospital could also be problematic. If a hurricane does impact Barnstable, areas could be cut off from services, which could impact emergency shelters or the ability to evacuate neighborhoods, most specifically, Osterville Grand Island and could reach the hospital itself. The U.S. Army Corps of Engineers (USACE) has recently updated the hurricane inundation maps for coastal Massachusetts. Each community received a map created using a Sea, Land, and Overland Surges from Hurricanes (SLOSH) model developed by the National Weather Service. The model estimates the potential for storm surge for categories 1-4 hurricanes. Figure 4 shows the varying degrees of inundation Barnstable may be able to expect from each type of hurricane. Access to Osterville Grand Island, which was previously mentioned as an area of concern, would potentially become limited or impossible during even a Category 1 event. Figure 4: Hurricane Inundation Zones Source: Massachusetts Hurricane Inundation Zones (arcgis.com) 3.2.2.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of Barnstable experiencing a hurricane is highly likely. Based on NOAA’s Adapting to Climate Change Guide3, the power and frequency of Atlantic Ocean hurricanes has increased in recent decades and the intensity of Atlantic hurricanes is likely to increase over the extended long term. Figure 5 shows the Number of Hurricanes for 100-year Return Period along the eastern seaboard. The light blue area over Massachusetts represents that the state can expect 20 to 40 hurricanes over a 100- year return period. 3 Source: NOAA’s Adapting to Climate Change: A Planning Guide for State Coastal Managers (2010) Town of Barnstable (233963.00) 3-13 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 5: Number of Hurricanes for a 100-year Return Period Source: 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan NOAA published a map (Figure 6) showing the possibility that a tropical storm or hurricane will affect a given area during the hurricane season. Based on this research, Massachusetts has a 6 to 30 percent chance of a tropical storm or hurricane impacting the state in any given year. There is a greater probability along the coast. Town of Barnstable (233963.00) 3-14 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 6: Probability of Hurricane or Tropical Storm Events across Massachusetts Source: http://www.aoml.noaa.gov/hrd/tcfaq/G11.html 3.2.3 Dam Failure Dam failures are a catastrophic type of failure characterized by the sudden, rapid, and uncontrolled release of water. They can result from natural events, human-induced events, or a combination of the two. Failures due to natural events such as prolonged periods of rainfall and flooding can result in overtopping, which is the most common cause of dam failure. 3.2.3.1 Hazard Location Barnstable currently has 10 dams in the community and three have been assigned a hazard potential classification of “significant.” The State determined that the Town is responsible for the ownership, maintenance, and operation of the Wequaquet Lake and Mill Pond Dams. The Lumbert Pond Dam is under private ownership. The Santuit Pond Dam in Mashpee has also been identified as a potential hazard for the town of Barnstable should the dam fail. Wequaquet Lake Dam - Wequaquet Lake is the largest lake in the Town of Barnstable and the third largest on Cape Cod. The 654-acre lake is located south of Route 6 and Route 132 in Centerville. The lake has 7.5 acres of shoreline that is heavily developed with cottages and year-round homes. The lake discharges through a man-made channel into Long Pond and ultimately to the Centerville River. The Wequaquet Lake dam consists of a concrete box culvert extending 37 feet under Phinney’s Lane with a concrete retaining wall on either side of the road. Although the dam carries a hazard ranking of “significant”, as of 2009, the condition of the dam is in satisfactory condition with no major deficiencies. Mill Pond Dam - Mill Pond is located northwest of the intersection of Route 28 and Route 149 in Marstons Mills. The warm-water pond is fed by the Marstons Mills River and discharges into wetlands adjacent to Prince Cove and ultimately to the Three Bays. The Mill Pond dam is 52 feet in length and located at the southeast end of the pond, just east west of Route 149. The dam structure consists of an uncontrolled spillway, a tier pool, and a fish ladder pool outlet. Flows then pass through a trash rack and a 4’ pipe culvert Town of Barnstable (233963.00) 3-15 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 extending 280 feet under Route 149. Although the dam carries a hazard ranking of “significant”, the dam is in fair condition, as determined by a December 2009 inspection. Santuit Pond Dam - Santuit Pond is located just west of Barnstable in the Town of Mashpee; however, the Santuit Pond dam is a potential hazard for the Town of Barnstable should this dam fail. Santuit Pond is a 172-acre warm-water pond approximately a mile north of Route 28 and east of Route 130. The MCDR has assigned the Santuit Pond dam a hazard ranking of significant. In 2013, a new fish ladder and dam separating the Santuit River from Santuit Pond was completed. A map showing the location of dams in Barnstable is located in Appendix B. 3.2.3.2 Previous Occurrences, Severity & Extent of the Hazard According to FEMA, there has not been a Presidential Disaster Declaration made for dam failures in the State of Massachusetts since 1953 nor have there been any instances in Barnstable. The Massachusetts Office of Dam Safety is responsible for maintaining records of dams statewide. The Office ensures compliance with practices pertaining to dam inspection, maintenance, repair and operation. As displayed in Table 3-5, the State utilizes the USACE classification system for the hazard potential of dam failures. The classification system outlines the expected impacts should a dam failure occur. Table 3-5: USACE Hazard Potential Classification Hazard Type Description High Hazard Refers to dams located where failure will likely cause loss of life and serious damage to home(s), industrial or commercial facilities, important public utilities, main highway(s) or railroad(s). Significant Hazards Refers to dams located where failure may cause loss of life and damage home(s), industrial or commercial facilities, secondary highway(s) or railroad(s) or cause interruption of use of service of relatively important facilities. Low Hazard Refers to dams located where failure may cause minimal property damage to others. Loss of life is not expected. According to Massachusetts State law, dam owners are required to prepare, maintain, and update Emergency Action Plans for all High Hazard Potential dams and certain Significant Hazard Potential dams. The Emergency Action Plans include the following information: Identification of equipment and materials required and available to execute the plan; Notification procedures for informing local emergency agencies; An inundation map that identifies potential flood areas; and A process for warning nearby residents if failure of the dam is imminent including a list of addresses and phone numbers for property owners who may be affected in the event of a dam failure. 3.2.3.3 Impact & Vulnerability The Town of Barnstable is vulnerable to dam failures. According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, as infrastructure ages and maintenance and inspection costs increase, there is an increased likelihood of higher risk for full or partial dam failures. The location of several significant hazard dams in Barnstable contributes its dam failure vulnerability. Should a dam failure occur, it would likely cause serious damage and potentially loss of life to the surrounding area. Town of Barnstable (233963.00) 3-16 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 3.2.3.4 Probability of Future Occurrence Based on the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future dam failures in Barnstable is unknown. Likelihood would increase if the following events did occur: Natural hazards such as an earthquake/flood; Deliberate acts of sabotage; Structural failure of dam materials; Dam structures are overtopped or about to be overtopped due to floodwaters; Earth embankments breached by erosion or slope failure; and Spillways are blocked or seepage exists downstream. 3.2.4 Earthquake Earthquakes are the result of a release of energy (which can be observed by shifting and fracturing of rock materials beneath the surface) in the Earth’s crust that creates seismic activity. Seismic activity is defined by the frequency, type and size of earthquakes that occur. Earthquakes are measured by the Richter magnitude scale or the Maximum Modified Mercalli Intensity Scale (MMI Scale) that assign a value number to each earthquake event as a form of measuring the energy released. Unfortunately, earthquakes can be large in magnitude, impact thousands of square miles and cause billions of dollars in damage to property. 3.2.4.1 Hazard Location Earthquakes are possible in Massachusetts, including Barnstable. The Northeast States Emergency Consortium map in Figure 7 indicates where the epicenters of specific events have occurred in the past. While an epicenter can be located far from Barnstable and still produce a Barnstable-affecting earthquake, the earthquake hazard possibility is low for the Northeast region in general. The rate of earthquakes in the Northeast is about 1% of the earthquake rate in California. A strongly damaging earthquake is expected once every 200-300 years in the Northeast. Town of Barnstable (233963.00) 3-17 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 7: Earthquakes in the Northeastern US and Adjacent Canada Source: Earthquakes Hazards: Northeast States Emergency Consortium (nesec.org) 2021 The 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan notes that the New England epicenters do not follow major mapped faults of the region, nor are they confined to specific geologic structures or terrain. In addition, past earthquakes in New England have not aligned along fault lines that are known or mapped by geologists. Due to the wide-ranging occurrences of earthquakes in New England, it is suspected that a strong event could occur anywhere in the region. 3.2.4.2 Previous Occurrences, Severity & Extent As of 2021, there has never been an earthquake recorded in the Town of Barnstable. According to FEMA, there has never been a Presidential Disaster Declaration made for an earthquake in the State of Massachusetts. Between 1668 - 2021, Massachusetts experienced 379 earthquakes of varying magnitudes.4 According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the last major earthquake to affect Massachusetts was more than 200 years ago in 1755 with an estimated magnitude of about 6.0 to 6.25. The epicenter was probably located off the coast of Cape Ann, north of Boston. The area of greatest damage in Massachusetts stretched along the northern coast of the state from Cape Ann to Boston. Figure 8 shows earthquakes in New England, the United States, and Canada from 1990-2010. Other earthquake events relevant to the Barnstable area are listed in Table 3-6. 4 The Northeast States Emergency Consortium, “Earthquakes,” [http://nesec.org/earthquakes-hazards/], 2021 Town of Barnstable (233963.00) 3-18 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 8: Earthquakes in New England, United States and Canada (1990 – 2010) Table 3-6: Earthquake Events Greater Than Magnitude 2.0 in Massachusetts Date Magnitude Location November 8, 2020 3.6 Bliss Corner December 3, 2019 2.1 Plymouth December 23, 2018 2.2 Gardner December 21, 2018 2.1 Templeton April 2012 4.4 Offshore May 15, 2011 2.1 Buzzard’s Bay July 22, 2003 3.6 Offshore October 25, 1965 5 Nantucket April 24, 1925 5 Wareham January 7, 1925 5.0 Cape Ann August 8, 1847 4.2 Brewster Town of Barnstable (233963.00) 3-19 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Date Magnitude Location January 2, 1785 5.4 Offshore November 18, 1755 6.0 Cape Ann Figure 9: Massachusetts Seismicity (1973 – 2021) Source: Information by Region - Massachusetts | U.S. Geological Survey (usgs.gov) Figure 9 is an earthquake hazard map, commonly referred to as a PGA map, for Massachusetts that shows ground motion values with a 2% probability in 50 years. For moderate earthquakes, PGA is the best determinate of damage. According to Figure 10, Barnstable has a 2% probability of having ground movement with a severity of 14 to 20%, equivalent to a VI on the MMI Scale.

According to the analysis there is a 66% chance that the next earthquake of magnitude 2.7 or greater in the region will occur in one of the green areas in Figure 11. Barnstable is in a higher probability area. Figure 11: Spatial Probabilities for New England Source: 2013 Massachusetts State Hazard Mitigation Plan Town of Barnstable (233963.00) 3-21 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Earthquake impacts are measured by how much energy releases from the epicenter of the event and how far any given location is from the epicenter. Severity can be expressed for an earthquake by comparing the acceleration of the event to normal acceleration due to gravity. Peak ground acceleration (PGA) is how the strength of the ground movements can be measured and is expressed as a percent of the established rate of acceleration due to gravity. A common method used to describe the severity of an earthquake is the MMI Scale (see Table 3-7). The MMI Scale has preceded the Richter Scale (used until 1970) to measure the size of earthquakes in terms of how much energy is released. The scale identifies 12 increasing levels of intensity which are designated by a Roman numeral. Table 3-7: Modified Mercalli Intensity Scale – Earthquake Intensity MMI Scale Number Typical Earthquake Impacts I Not felt except by a very few under especially favorable conditions. II Felt only by a few persons at rest, especially on upper floors of buildings. III Felt quite noticeably by persons indoors, especially on upper floors of buildings. Many people do not recognize it as an earthquake. Standing motor cars may rock slightly. Vibrations similar to the passing of a truck. Duration estimated. IV Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound. Sensation like heavy truck striking building. Standing motor cars rocked noticeably. V Felt by nearly everyone; many awakened. Some dishes, windows broken. Unstable objects overturned. Pendulum clocks may stop. VI Felt by all, many frightened. Some heavy furniture moved; a few instances of fallen plaster. Damage slight. VII Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken. VIII Damage slight in specially designed structures; considerable damage in ordinary substantial buildings with partial collapse. Damage great in poorly built structures. Fall of chimneys, factory stacks, columns, monuments, walls. Heavy furniture overturned. IX Damage considerable in specially designed structures. Damage great in substantial buildings, with partial collapse. Buildings shifted off foundations. X Some well-built wooden structures destroyed; most masonry and frame structures destroyed with foundations. Rails bent. XI Few, if any (masonry) structures remain standing. Bridges destroyed.

Can totally destroy communities near the epicenter.One every 5 to 10 years 3.2.4.3 Impact & Vulnerability Barnstable is vulnerable to earthquakes according to data provided by Weston Observatory and USGS earthquake hazard maps. In general, earthquake vulnerability is based on cross referencing the built environment with the population for an area. Developed areas in high hazard zones are the most vulnerable due to their densely developed nature, age of structures and infrastructure and number of people. Structures that are newer construction are more resistant to earthquakes than older construction due to updated building codes and enforcement. Common impacts of an earthquake may include building and infrastructure damage or failure, rupture of underground utilities, fire, landslides and other disruptions. Secondary impacts of earthquakes can be just as serious and may include dam failure or explosions. 3.2.4.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future earthquakes in Barnstable is likely even though they cannot be predicted and may occur anytime. The State Plan also reports there have been 366 earthquakes of varying degrees recorded from 1627 to 2012 in Massachusetts. Due to inferior recording and reporting instruments, prior to the 20th century, it is difficult to estimate the probability of future occurrences based on historical data. As also noted in the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, a 1994 USGS report found that the probability of a magnitude 5.0 or greater earthquake centered in New England in a 10-year period is about 10%-15%. The probability is expected to rise to 41% - 56% for a 50-year period. The last earthquake with a magnitude above 5.0 took place in New Hampshire’s Ossipee Mountains in 1940. 3.2.5 Wildfire Wildfires are typically non-structural fires that occur in vegetated areas such as grass, shrubs and forested areas. In Massachusetts, the cause of a wildfire can either be the result of human impacts or natural events such as a lightning strike. Drought and/or windstorm conditions can fuel wildfires or cause them to spread rapidly. Wildfires not only destroy the vegetated areas where they occur, but they can also impact the built environment including structures, if in close proximity. 3.2.5.1 Hazard Location According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the southern part of Massachusetts is particularly susceptible to wildfire due to the availability of fuel, impact of offshore winds and increasing development. The Plan notes that a US Forest Service study identified Barnstable and Plymouth Counties as the most fire-prone due to their vegetation, sandy soil, and the presence of a drying wind. Pitch pine and oak forests are especially susceptible to wildfires. Areas on Cape Cod have some high susceptibility and in Barnstable, this is particularly true along the north coast of the community. Figure 12 displays the wildfire throughout the state by Census block. Town of Barnstable (233963.00) 3-23 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 12: Wildfire Hazard Areas The 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan outlines regions from no risk to extreme risk of wildfire. Barnstable’s vegetated areas are at high risk of wildfire, while the salt marsh regions are at no risk of burning as show in Figure 13. Figure 13: Wildfire Risk Areas for the Commonwealth of Massachusetts Town of Barnstable (233963.00) 3-24 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 3.2.5.2 Previous Occurrences, Severity & Extent According to FEMA, there have been no Presidential Disaster Declarations made for wildfire in Massachusetts since 1953. The NCDC tracks storm events and there have been no reported instances of wildfire in Barnstable County. The 2013 Massachusetts State Hazard Mitigation Plan mapped the number of wildfire events statewide from 2001 to 2009 in Figure 13b. The figure illustrates, based on best available data, there were between 0-20 fires burning less than 100 acres during the eight-year span and some of the more substantial ones were in or near Barnstable. Figure 13b: Locations of Historical Wildfires and Acres Burned in Massachusetts (2001-2009) Source: 2013 Massachusetts State Hazard Mitigation Plan 3.2.5.3 Impact & Vulnerability Over the course of Barnstable’s development, urban areas, both residential and commercial, have encroached into natural wildlife areas. People, structures, and facilities in urban/wildland interface areas are at the greatest risk from wildfires. The vast majority of wildfires are started by humans; some fires are attributable to accidents and negligence, but historically almost half have been attributed to arson. Although most wildfires begin unnaturally, it is important to keep in mind that wildfires can play an important role in the natural cycle of plant succession and can have positive impacts on wildlife areas. These benefits should be considered when developing mitigation actions and response strategies. Barnstable is vulnerable to wildfires because of the type and amount of potential fuel in the community for this type of natural hazard event. The Cape is one of the highest risk areas for wildfire in the state; a U.S. Forest Service study found that Barnstable and Plymouth counties, with their sandy soils, drying winds and fuel types are as wildfire prone as the often fire ravaged regions of southern California. According to the Massachusetts Executive Office of Public Safety and Security, there are three classes of wildfires: surface fire, ground fire and crown fire. Crown fires would likely have the greatest probability of causing the greatest losses because of the speed at which the fire spreads. Town of Barnstable (233963.00) 3-25 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 The 2012 Barnstable County Wildfire Preparedness Plan included the preparation of wildfire risk areas (shown in Figure 14) which illustrates the areas of greatest wildfire risk on Cape Cod and in Barnstable. According to the assessment, portions of Barnstable are classified as “high” risk wildfire areas or areas for mitigation activities. Figure 14: Wildfire Risk Areas 3.2.5.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future wildfires in Barnstable is likely. Wildfires are likely to most often occur in Barnstable County (including Barnstable) from late March to early June. 3.2.6 Flood A flood is when there is a high flow or inundation of water that submerges land which is normally dry and causes or threatens damage. The most frequently flooded type of area is land adjacent to a water body and in a defined floodplain. Flooding can either be coastal, riverine or shallow flooding (associated with ponding or urban drainage). Flooding situations can develop slowly or very quickly in a situation known as a flash flood. Floods can be dangerous because the flow of water can be rapid and either impact a neighborhood, community or the larger watershed area. Varying types of floods can occur including5: Coastal Flood: Flooding of coastal areas due to the vertical rise above normal water level caused by strong, persistent onshore wind, high astronomical tide, and/or low atmospheric pressure, resulting in damage, 5 National Weather Service Instruction 10-1605 (August 17, 2007), Operations and Services Performance, NWSPD 10-16 Storm Data Preparation document (http://www.nws.noaa.gov/directives) Town of Barnstable (233963.00) 3-26 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 erosion, flooding, fatalities, or injuries. Coastal areas are defined as those portions of coastal land zones (coastal county/parish) adjacent to the waters and bays of the oceans. Farther inland, flood events are defined as Flash Flood or Flood. Terrain (elevation) features determine how far inland the coastal flooding extends. Flash Flood: Rapid and extreme flow of high water into a normally dry area, or a rapid water level rise in a stream or creek above a predetermined flood level, beginning within six hours of the causative event (e.g., intense rainfall, dam failure, ice jam-related), on a widespread or localized basis. Ongoing flooding can intensify to flash flooding in cases where intense rainfall results in a rapid surge of rising flood waters. Flash floods do not exist for two or three consecutive days. Riverine Flooding: The flooding of rivers and streams over their pre-defined banks. In coastal regions, the riverine floodplain is generally a flat area along a larger river or in low-lying coastal areas. The volume that is manageable depends on the watershed, and climate and land use characteristics. Spring snowmelt, frozen ground conditions, and strong storms may all lead to riverine flooding. Urban Flooding: In densely developed areas, heavy rains/precipitation can produce flooding when groundwater levels are high and there is insufficient drainage infrastructure in place. Other terminology frequently used to describe flood conditions includes: Base Flood (100 Year Flood) – Flood that has a 1% chance of being equaled or exceeded in any given year. A 100 Year flood can occur more than once in a short period of time. The term measures the size of the flood, not frequency of occurrence. 500 Year Flood – Flood that has a .2% chance of being equaled or exceeded in any given year. The 500- Year flood is an infrequent event and can occur between once in eight years to once in fifty years. The term does not mean a flood occurs once in 500 years. 3.2.6.1 Hazard Location Flooding is a regular occurrence in Massachusetts and is also one of the highest impact hazards. This type of natural hazard event typically occurs during other weather events like a hurricane, nor’easter, winter storm or heavy rain. The 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan indicates that flooding affects the majority of communities in the state. FEMA defines flood hazard areas on the Flood Insurance Rate Maps (FIRMs) as Special Flood Hazard Areas (SFHA). A SFHA is an area that will be inundated or impacted by the flood event that has a 1% chance of happening during the year. At times, the 1% annual chance of flood is called the base flood. The flood areas are defined as follows: Special Flood Hazard Areas o Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, Zone V1-V30 Moderate Flood Hazard Areas o Zone X (areas between the base flood and the .2% annual chance (or 500-year flood) Areas of Minimal Flood Hazard o Zone X (areas of minimal flood hazard, outside the SFHA and higher than the elevation of the .2% annual chance of flood) Areas at risk for flooding are shown in Appendix B. According to the Barnstable County Flood Insurance Study (2016), flooding in the Town of Barnstable is generally limited to coastal areas where waters can inundate during high tide conditions. The NFIP tracks information regarding the number of flood insurance policies in force, the dollar value in force, total losses and total payments as shown in Table 3-9. Town of Barnstable (233963.00) 3-27 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Table 3-9: National Flood Insurance Program (NFIP) – Barnstable # Policies in Force Premium Coverage Total Claims 1978-2016 Total Payments 1978-2016 1,189 $341,069,900 301 $3,058,512 3.2.6.2 Previous Occurrences, Severity & Extent In the past 50 years, there have been 20 major flood events in Massachusetts. The coastal counties experienced the greatest number of federal declarations. According to FEMA, there have been 17 Presidential Disaster declarations for a flooding incident in Massachusetts and six of those have impacted Barnstable County (see Table 3-10).

Widespread power outages accompanied high winds (greater than 60mph) and nearly two feet of snowfall. March 2, 2018 – Nor-easter brought floodwaters making Route 6A impassable and flooding the Barnstable Marine parking area. Waterflow was under and around buildings and damaged windows and sidings. Beaches and dunes suffered erosion and overwashing after water breached barrier beaches. Wrack infiltrated wetlands. January 4, 2018 – The storm of record, bringing high waters up to 100-year floodplain and damaging winds. Structures had waterflow around and under them and damage affected stairs, decks, windows, sidings, walls, and roofs. Other effects included eroded beaches, damaged sand fencing, overwashed dunes, and wrack in wetlands. The Milway neighborhood experienced major damage and most structures were flooded. November 11, 2014 – Heavy rain and strong wind impacted Cape Cod and two cars became stuck in flood waters on Megan Road in Hyannis. January 3, 2014 – Moderate coastal flooding impacted various parts of Cape Cod. June 3, 2012 – Sandy Neck Road in Barnstable was flooded and impassable due to minor coastal flooding. February 6-7, 1978 – Blizzard of the century permanently altered the shape of Cape Cod and nearly one hundred lives were lost across the Massachusetts coastal region. Waves as high as thirty feet and a seventeen-foot tide caused extensive flooding damage. Heavy snow and rain fell across the cape and many residents experienced power outages, stranded vehicles, and property damage. 3.2.6.3 Impact & Vulnerability The Town of Barnstable is highly susceptible to coastal flooding, but inland flooding is also a risk. Flooding results from heavy rains and storm surges and can be exacerbated by tidal restrictions and coastal erosion. The most dangerous type of flooding occurs from storm surges, which can accompany hurricane and nor’easter events. Storm surge is a dome of water that comes ashore during or after a hurricane event. Flooding from storm surges poses the greatest risk to life during hurricanes and necessitates evacuation of vulnerable areas. Storm surges can wash out roads, damage infrastructure, overwhelm storm sewers, and contaminate drinking water. Local staff noted that Hyannis Harbor and the surrounding area floods on a consistent basis. Flooding occurrences can have devastating impacts on life, property and operations in a community – particularly if the proper flood insurance is not in place. Throughout Massachusetts, there are no areas that are exempt from flooding Town of Barnstable (233963.00) 3-29 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 impacts, what varies is the type of flooding. Flooding can also alter the natural landscape and habitat areas and in Barnstable, this has been seen in the Sandy Neck area of the community on the northern coastline. Barnstable’s pump stations have flooded in the past. The community has set up a system where if a storm event may be predicted which could result in flooding, they have the ability to vacuum shut pump stations with the proper advanced warning. Other emergency systems in place include the use of installed and portable generators. During a large storm event, staff may intentionally and strategically shut down some pump stations. There are also health impacts which can be associated with flooding, such as potential exposure to mold, pathogens in flood waters and long-term mental health issues. Rebuilding homes and buildings impacted by flooding can be extremely costly and time consuming. There is also a risk that rebuilding costs may be repetitive as often the same locations can be impacted more than once. 3.2.6.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of Barnstable experiencing a flood event is highly likely. The historical record indicates that the State experienced 20 flood-related disaster declarations from 1955 to 2012. Therefore, based on statistics, a flood event of disaster declaration proportions may occur somewhere in Massachusetts once every three years. 3.2.7 Nor’easter/Coastal Storm A nor’easter is a non-tropical storm that produces gale-force winds and precipitation in the form of heavy rain or snow. Nor’easters (also referred to as coastal storms) are common occurrences in the eastern United States. Events may cause substantial damage to coastal (and at times, inland) areas due to strong winds (can be hurricane force), storm surge and substantial rainfall or snow amounts. A storm is specifically a Nor’easter when the wind blows in from the northeast and pushes the storm up the east coast of the United States. Due to the slow movement of these weather events, storm surge can be in excess of 2 feet above normal high tide and impact the coastline over multiple high tide cycles making coastal erosion and flooding a common secondary effect of these storm events. These types of storms can occur anytime of the year but are more common in the winter months. 3.2.7.1 Hazard Location In Massachusetts, typically one or two nor’easter events impact the coastline between October and April each year which may cause flooding, property damage and coastal erosion. The coastal areas of Barnstable are susceptible to property and natural resource damage from storm surge and wind while the entire community is often impacted by heavy rain, flooding and snow associated with nor’easter events. 3.2.7.2 Previous Occurrences, Severity & Extent Nor’easters are the most frequently occurring natural hazard in the state. According to FEMA, there have been four Presidential Disaster Declarations made for “Coastal Storms” in the State of Massachusetts. In Barnstable, there have been varying degrees of impacts from the storms listed (Table 3-11). Town of Barnstable (233963.00) 3-30 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Table 3-11: Massachusetts Coastal Storm Major Disaster Declarations (1953 – Present) Disaster No.Incident Period Date Disaster Declared Barnstable County a Designated Area?

The following is a list of some nor’easter events that have impacted Barnstable County in the past. January 2015 – Winter storm Juno impacted New England and a state of emergency was declared for Massachusetts. In Barnstable County, there were power outages, shelters were opened and there was heavy snow, storm surge, coastal flooding and erosion throughout Cape Cod. This event resulted in a federal disaster declaration (FEMA DR-4214). In Barnstable, shelters were open and over 200 people were served. October 29, 2012 – Hurricane Sandy brought high winds and coastal flooding to the area with storm surge reports of 2.5 – 4.5 feet. April 15-16, 2007 – Nor’easter caused widespread impacts to portions of Massachusetts. Some areas were impacted by coastal flooding while others experienced debris, snow, river and stream flooding. October-November 1991 – A large nor’easter occurred, and it was unusual because it moved south and strengthened when it joined with Hurricane Grace producing what is known as the “perfect storm”. Winds measured over 80 mph with waves over 30 feet high in some parts of the coastline. February 1978 – A blizzard/nor’easter produced 8-12 inches of snow, ice and flooding and damaged buildings and infrastructure across Barnstable County. 3.2.7.3 Impact & Vulnerability Barnstable is vulnerable to nor’easter occurrence events in the future as they will continue to impact the community and all of Cape Cod. Impacts will be seen from the heavy rain, wind, snow, storm surge, flooding and erosion from this type of weather events. Depending on the length and strength of the storm, death or serious injury, property damage and operations of local government and businesses can all occur. A common secondary impact of a coastal storm is short- and long-term electrical power outages. Nor’easters are a serious concern because of the damage potential and frequent rate of occurrence. Town of Barnstable (233963.00) 3-31 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 3.2.7.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of Barnstable experiencing a nor’easter is highly likely. The historical record for the State indicates that there have been three nor’easter-related federally declared disasters between 1954 and 2012. The State Plan notes that this figure likely underestimates how often nor’easters occur and impact Massachusetts. 3.2.8 Windstorm In general, wind is the horizontal motion of the air past a given point. Wind is in constant motion and windstorms can occur suddenly and without warning. Differences in air pressure is how a wind event begins and pressure that is higher at one place versus another sets up a force that pushes from the high toward the low pressure. Wind is used to describe the prevailing direction from which the air is blowing with the speed given usually in miles per hour or knots. Extreme wind events are more often associated with a larger meteorological event such as a winter storm, hurricane, tornado, nor’easter or severe thunderstorm. In the absence of accompanying characteristics of these other events, the event would be considered a windstorm. 3.2.8.1 Hazard Location According to FEMA’s Winds Zone map (see Figure 15), the entire state of Massachusetts is susceptible to wind speeds. The map indicates various areas of the United States and their susceptibility to wind speeds in addition to highlighting Special Wind and Hurricane-Susceptible regions. Barnstable is located in a Zone II, as is the rest of the state, which means the community is susceptible to winds of up to 160 mph and is also located in a hurricane susceptible region. Town of Barnstable (233963.00) 3-32 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 15: Wind Zones in the United States 3.2.8.2 Previous Occurrences, Severity & Extent Windstorm occurrences may be classified by the NWS as a Wind Advisory (winds sustained at 31-39 mph for at least an hour or gusts of 46-57 mph) or a High Wind Warning (sustained winds 40+ mph or gusts of 58+mph). Wind that is measured at less than 30 mph does not typically create a hazardous condition. Windstorm events can occur regularly in Barnstable. The entire State of Massachusetts is susceptible to both extreme wind events such as hurricanes and tornadoes but also windstorms that do not have any other associated characteristics other than the movement of air (i.e., no precipitation). Impacts of a high wind event may include fallen trees or power lines, roof damage and dangerous marine conditions. According to the Massachusetts Hazard Mitigation Plan, the state is susceptible to high winds from extreme weather events and before and after frontal systems. The information in Table 3-12 was available for high wind (wind gusts greater than 55 knots) occurrences in Barnstable County from February 2006 to February 2016.

Impacts may include power outages that can impact residents and businesses, downed power lines, severe marine forecast that could damage coastal infrastructure and downed trees and branches. 3.2.8.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future windstorms in Barnstable is highly likely. The community is also susceptible to other natural hazards that typically have wind associated characteristics. Town of Barnstable (233963.00) 3-34 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 3.2.9 Tornado Tornadoes typically appear as a violently rotating visible funnel cloud that is a rotating air column in contact with the ground. A loud, freight train-like, roaring noise will accompany a tornado. Wind speeds can range from 40 mph to 300 mph and are measured on what is known as the Fujita scale. Tornadoes generate in strong atmospheric winds where cool, dry air meets warm, humid air. Damage from a tornado can vary widely and be minimal to completely catastrophic. On a local level, a tornado is the most destructive of all atmospheric conditions. In Massachusetts, tornadoes are not a common occurrence, with an average of 1.7 events per year, mostly in central counties. 3.2.9.1 Hazard Location Barnstable County is vulnerable to tornadoes. Based on the wind zone map provided earlier in the Windstorm section, Massachusetts is in wind zone II that can include winds up to 160 mph which may be associated with tornadoes. Tornadoes can occur in any region of Massachusetts. According to Figure 16, Massachusetts experienced one tornado event annually between 1991 and 2010. Figure 16: Annual Average Number of Tornadoes (1991 – 2010) Source: http://www1.ncdc.noaa.gov/pub/data/cmb/images/tornado/clim/ann-avg-torn1991-2010.gif 3.2.9.2 Previous Occurrences, Severity & Extent Since 1950, two F1 tornadoes have been recorded in Barnstable County (August 9, 1968 and August 22, 1977). There were no fatalities associated with the events. One occurrence was directly in Barnstable while the other was in nearby Osterville (see Figure 17). Town of Barnstable (233963.00) 3-35 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 17: Barnstable County Tornadoes (1950 – 2021) Source: Barnstable County Tornadoes, 1950 – 2021, Massachusetts Tornadoes (tornadoproject.com) Since 1954, there have been two Major Disaster Declarations in the State of Massachusetts for Tornadoes (see Table 3-13). The State Hazard Mitigation plan indicates that a tornado may occur anywhere in Massachusetts with the right atmospheric conditions and typically, there are 1-3 tornados in New England per year. Table 3-13: Massachusetts Tornado Major Disaster Declarations (1954 – Present) Disaster No.Incident Period Date Disaster Declared Barnstable County a Designated Area?

The degree of damage helps to define the rating of an individual storm. The EF-scale below (Figure 18) has been updated and in use since 2007. Town of Barnstable (233963.00) 3-36 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 18: Enhanced Fujita Scale NOAA Storm Prediction Center issues tornado watches and warnings. A watch means tornadoes are possible and a warning means a tornado has been sighed or indicated by weather radar. The current average lead time for tornado warnings is only 13 minutes resulting in greater emphasis being placed on a watch for tornado preparedness compared to other hazards. 3.2.9.3 Impact & Vulnerability Barnstable is vulnerable to tornadoes and in Barnstable County, since 1951, there have been two recorded F1 tornadoes. The impact of a tornado can be sudden and significant with regard to property, human life and infrastructure. Heavy winds and hail are often associated with a tornado and injuries and fatalities can result from flying debris, building damage or being outside without cover. Post tornado, there are still dangerous situations due to damaged buildings, power outages and downed power lines and either delayed or inability to receive emergency services. Property and operation impacts include damage to residential and commercial buildings, trees and vegetation, and exposed infrastructure that can be destroyed by a tornado. Damaged bridges and infrastructure may be weakened for use resulting in delays for individuals to move within the community to receive basic services. Although tornadoes are confined to certain areas, the impacts on communities affected can be devastating with major damage and destruction. 3.2.9.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future tornadoes in Barnstable is unlikely. NOAA’s National Severe Storm Laboratory (NSSL) has estimated the likelihood for a tornado on a given day in the United States. The probability for a tornado in Massachusetts is 0.2 to 0.4 days per year based on tornado data from 1995 to 2020. Figure 19 shows tornado tracks across the United States from 1950-2019. Town of Barnstable (233963.00) 3-37 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 19: Tornadoes in the United States 3.2.10 Drought Drought occurs when there is an insufficient amount of moisture that has adverse impacts on people, animals or vegetation over a geographic area. Drought can occur over a prolonged period of time where the lack of precipitation directly impacts the hydrologic balance of the environment. Examples of impact include water supply shortages, dry soils which may result in crop failure and changed fish and wildlife behavior including death. Other weather characteristics like consistently high temperatures and low humidity can exacerbate the problem. Results of prolonged drought periods can also have a disastrous economic impact on communities and regions that rely upon water for agriculture and tourism. 3.2.10.1 Hazard Location Massachusetts generally receives between 40 and 50 inches of precipitation on an annual basis, but it is not immune from experiencing drought conditions which often occur when there has been a dry winter. Barnstable and all of Cape Cod could be affected by drought. Figure 20 indicates the number of drought occurrences based on precipitation indices for each of the six drought regions in Massachusetts. Town of Barnstable (233963.00) 3-38 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 20: Drought Emergencies Per 100 Years in Massachusetts Source: 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan 3.2.10.2 Previous Occurrences, Severity & Extent According to FEMA, there has never been a Presidential Disaster Declaration made for drought in the State of Massachusetts. The NCDC Storm Events Database listed the following two drought occurrence in Barnstable County: April to May 2012 – The U.S. Drought Monitor declared a severe drought across the eastern half of Massachusetts, Rhode Island and a portion of Connecticut from April 12 – May 15, 2012. Precipitation had been half of the normal amount between January 2012 and April 2012, which caused rivers and streams to run at low levels during the spring run-off season. One major impact of this meteorological drought was an increase in fire danger. August to November 2016 – The U.S. Drought Monitor expanded the ongoing drought in New England to include Barnstable County of August 30th, 2016, after a month of receiving below-average rainfall. The designation for Barnstable was upgraded to a Severe Drought (D2) at the beginning of October through October 11 when it was downgraded to Moderate Drought (D1). The Moderate Drought continued through the end of November 2016 as rainfall and streamflow continued at below-normal levels. The most severe drought, on record, in Massachusetts occurred from 1961 - 1969. The eastern portion of the state experienced two drought scenarios in the past ten years, or an average of 0.18 drought events per year. As noted in the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the drought in 2016 was the most extensive drought event in Massachusetts since the 1960s. According to the Massachusetts Drought Management Plan, a number of drought indices are available to assess the various impacts of dry conditions. The state uses a multi-index system that takes advantage of several of these indices to determine the severity of a given drought or extended period of dry conditions. Town of Barnstable (233963.00) 3-39 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 3.2.10.3 Drought Indices6 Palmer Drought Index (PDI) – an index that reflects soil moisture and weather conditions, available from the National Weather Service or National Climate Data Center. Crop Moisture Index (CMI) – an index that reflects short-term soil moisture conditions as used for agriculture, available from the National Climate Data Center. Fire Danger – the fire danger level reflects how favorable conditions are for brush fires. Data factored into the index include weather conditions and available fuel. This is a short-term index, which can change daily. The duration of the index will be used to determine relative drought levels. Precipitation – a comparison of measured precipitation amounts to 30-year averages. Cumulative amounts for 3, 6 and 12-month periods are factored into the drought determination. This data is available from the DCR, Office of Water Resources. Groundwater Levels – a drought level determination is based on the number of consecutive months groundwater levels are below normal (lowest 25% of period of record). Groundwater conditions maps showing areas of above normal, normal and below normal are provided monthly by the USGS. Streamflows – a drought level determination is based on the number of consecutive months streamflow levels are below normal (lowest 25% of period of record). Streamflow condition maps showing areas of above normal, normal and below normal are provided monthly by the U.S. Geological Survey. Reservoirs – a drought level determination will be based on the level of small, medium and large index reservoirs across the state. The reservoir level relative to normal conditions will be considered. DCR and Office of Water Resources, as part of its monthly conditions report, will maintain a list of index water supply reservoirs and their percent full. Table 3-14 defines the drought indices for Massachusetts according to the 2013 Drought Management Plan. 6 Massachusetts Drought Management Plan, 2013, website: http://www.mass.gov/eea/docs/eea/wrc/droughtplan.pdf Town of Barnstable (233963.00) 3-40 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Table 3-14: Drought Index Indices (Massachusetts Drought Management Plan, 2013) Drought Level PDI CMI* Fire* Precipitation Groundwater Streamflow Reservoir Normal -1.0 to –1.99 0.0 to -1.0 slightly dry Low 1 month below normal 2 consecutive months below normal** 1 month below normal** Reservoir levels at or near normal for the time of year Advisory -2.0 to -2.99 -1.0 to –1.9 abnormally dry Moderate 2 month cumulative below 65% of normal 3 consecutive months below normal** At least 2 out of 3 consecutive months below normal** Small index Reservoirs below normal Watch -3.0 to 3.99 -2.0 to –2.9 excessively dry High 1 of the following criteria met: 3 month cumulative. < 65% or 6 month cumulative < 70% or 12 month cumulative < 70% 4-5 consecutive months below normal** At least 4 out of 5 consecutive months below normal** Medium index Reservoirs below normal Warning -4.0 and below < -2.9 severely dry V.

According to the Massachusetts Department of Conservation and Recreation, the Cape receives on average, 44 inches of precipitation. Barnstable is vulnerable to drought which can cause public safety, health and social impacts. Drought can impact agriculture, wildlife, recreation, energy usage, municipal business, fish and wildlife and their associated habitats. The majority of the Town of Barnstable, with the exception of west Barnstable, receives its water from the Hyannis Water System which consists of four water treatment facilities, two storage tanks, 12 well pumping stations and 107 miles of distribution system. Supplying its drinking water from ground sources, the Hyannis Water System draws about 2.77 million gallons per day (MGD) from wells with an annual production of 902 million gallons. The Hyannis Water System is currently registered through the Department of Environmental Protection (DEP) to withdraw water from twelve groundwater wells. The duration and frequency of drought is what would determine how it would impact the water supply. Decreasing flow of streams and rivers due to a lack of precipitation can secondarily impact drinking water supplies, wildlife and recreational activities. It can also affect other users such as power generation and water and wastewater utilities. In Barnstable, drought conditions could impact landscaping, and potable water for homeowner and business use. 3.2.10.5 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future drought events in Barnstable is likely. The 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, designated drought as a low frequency hazard even though there is a potential for widespread impact. 3.2.11 Severe Winter Weather Winter storms typically consist of varying forms of precipitation including snow, sleet, freezing rain or a mix of these wintry conditions. Blizzards are the most dangerous and severe type of winter storm and are characterized by strong, sustained winds of at least 35 mph that last for a prolonged period of time – typically 3 hours or more. An ice storm is another form of winter storm that is defined as an event which results in the accumulation of at least .25-inch of ice on exposed surfaces and they occur when moisture falls and freezes immediately upon impact on trees, power lines, roads, structures and other surfaces. These types of storms can down trees, cause lengthy, widespread power outages, damage property and even cause fatalities. 3.2.11.1 Hazard Location Winter storms are common on an annual basis throughout Massachusetts. Figure 21 represents the normal (30-year average) annual snow totals in New England. The entire State of Massachusetts is at risk of snow, higher snow accumulations appear to be more common at higher elevations in Western and Central Massachusetts. Despite the ocean moisture and coastal proximity, Barnstable is susceptible to a combination of both snow and coastal flooding during a winter storm event.

Gusts of wind were measured at 64 mph. January 2015 – Blizzard conditions occurred on Cape Cod including at the Barnstable municipal airport. Between fourteen and thirty inches of snow fell across Cape Cod. March 2014 – This storm consisted of strong winds (gusts of over 80 mph) and heavy snow. Town of Barnstable (233963.00) 3-44 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 NOAA’s NCDC has implemented the Regional Snowfall Index (RSI) to categorize significant snowstorms that impact the eastern two thirds of the United States. RSI includes a regional index for the northeast that includes Massachusetts and replaced with the Northeast Snowfall Impact Scale (NESIS) to account for snowfall accumulations, population data, and area affected (see Table 3-17). The index is similar to the Fujita scale for tornadoes or the Saffir-Simpson scale for hurricanes. Table 3-17: NCDC Regional Snowfall Index (RSI) Category RSI Value Description 1 1-3 Notable 2 3-6 Significant 3 6-10 Major 4 10-18 Crippling 5 18.0+Extreme 3.2.11.3 Impact & Vulnerability Barnstable is vulnerable to winter storm events. Winter storm events on Cape Cod are typically associated with heavy snow, high winds, storm surge and flooding which makes the coastline especially vulnerable to flooding. The Barnstable County Hazard Mitigation Plan notes that winter storms that impact Cape Cod tend to have the most effect on the north shore. As a developed coastline, particularly in Barnstable, infrastructure is at risk and may be impacted directly by the winter storm event or by associated power outages and the inability to use safe transportation routes. Route 6 is the main roadway in and out of Cape Cod and it also serves as the evacuation route but during winter storm events, may become impassable. Impacts to property and operations are usually temporary and include snow removal. However, heavy snow can lead to significant snow removal costs, infrastructure damages (such as weight of snow on roofs), and loss of business that can financially impact communities. Other potential impacts include knocked down trees, power lines, and utility poles. Freezing temperatures can result in downed trees, power lines, utility poles, ice jams that can cause flooding, and building pipe bursts due to poor insulation or lack of heat. Risks related to snow and ice are most often associated with automobile accidents followed by individuals caught outside in the storm. Winter storms can also result in fatalities that are most often not directly related to the storm itself. Fatalities due to traffic accidents on icy roads, heart attacks from excessive shoveling, and hypothermia from prolonged exposure to the cold are typical. Fatalities due to cold exposure are most often associated with infants and the elderly that are most susceptible. During winter storm Juno in January 2015, Barnstable sheltered over 200 residents. In reflecting on this event, local staff indicated a challenge in the community is the number of older or elderly residents that don’t require hospitalization but have medical conditions or medications that need to be taken. A potential collaboration with Cape Cod hospital to monitor these residents as “social admits” in the future may be necessary. The DPW Director noted during the discussion of whether or not the community should reconsider opening shelters for each village in the community that it is hard for DPW to keep roads open during a winter storm if there are many shelters open. It is easier to focus on one facility and the need to keep that access point open during an emergency. Another area of concern is long term power loss because much of West Barnstable is served by wells, and if residents lose the ability to have clean water, water quality could quickly become a problem. In the summer of 2015, the Barnstable DPW conducted a Snow and Ice workshop to discuss snow and ice operations in the community. Some of the outcomes included adoption of a GPS based form of snow management and snow removal crew management and rest policies. Communicating through the Town website has been effective but there Town of Barnstable (233963.00) 3-45 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 should also be a way for citizens to call and hear a recorded version of the website message for those that do not have computer access. Better utilization of Channel 18 and radio announcements could also enhance communication efforts. 3.2.11.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of Barnstable experiencing a winter storm is highly likely. Research indicates that the entire state is at risk for frequent winter storms. Moderate storms frequently impact Cape Cod and in addition to snow and ice accumulation and wind hazards, winter storms can produce storm surges and coastal erosion, particularly affecting Barnstable’s north coast. 3.2.12 Tsunami A tsunami occurrence is typically characterized by a series of waves that are generated by an undersea disturbance such as an earthquake, landslide, meteorite impact, glacier calving, or volcanic eruption. According to NOAA, the speed of a tsunami can range from 500 miles per hour to 20-30 miles per hour in shallower coastline conditions. A tsunami is different from a regular ocean wave because it is associated with a current that travels from the water surface down to the ocean floor. As tsunami waves approach shore, they slow down and cause a “wave pile-up” which causes wave heights to increase along with a continuously flowing “wall of water” which can cause devastating damage in coastal areas. Tsunamis are rare, but not unprecedented in the Atlantic Ocean. For a tsunami to cause major damage, there must be an earthquake of a magnitude of at least 7 with an epicenter in the ocean. This is rare on the East Coast. 3.2.12.1 Hazard Location The largest source region for tsunamis is the Pacific Ocean with approximately 70 percent of all world occurrences. Within the continental United States, the most vulnerable states are those located near the Pacific Ocean. Figure 22 shows seven earthquake events that have caused tsunamis in the United States. The coastal areas of Massachusetts are exposed to the threat of tsunamis. Tsunamis on the East Coast of the United States are rare and the primary source of tsunamis is from landslides that occur along the continental slope in the Atlantic Ocean. Town of Barnstable (233963.00) 3-46 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 22: Earthquake Generated Tsunamis in the United States from 1900 to 1964 3.2.12.2 Previous Occurrences, Severity & Extent According to FEMA, there has not been a Presidential Disaster Declarations made for tsunamis in the State of Massachusetts since 1953. A significant tsunami has never struck the Massachusetts coast. The NCDC Storm Events Database does not report a tsunami occurring in any part of Massachusetts. Figure 23 displays how many tsunami events have occurred in the Atlantic Ocean causing run-up heights of 0.01 m to greater than 3.0 m for U.S. states and territories. The figure shows how there have been no occurrences of tsunamis along the Eastern continental U.S. Town of Barnstable (233963.00) 3-47 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Figure 23: Total Number of Tsunami Events According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future tsunamis in Barnstable is unlikely. The likelihood of damaging tsunami along the Massachusetts coastline is low compared to other hazards; however, the impacts could be very high. Most destructive tsunamis are classified as local or regional and caused by earthquakes. A tsunami is classified according to its intensity; often characterized by one of the following types: Microtsunami – tsunami with a small amplitude that must be observed with instruments but is not observed visually. Local Tsunami – tsunami with destructive effects confined to the coast, usually caused from a nearby source less than 200 km (124 miles) away. Tsunami is usually generated by a small earthquake or landslide. Regional Tsunami – tsunami capable of destruction in a geographic region, generally within 1,000 km (621 miles) of its source. Pacific-wide tsunami – tsunami capable of widespread destruction in an immediate region or across the Pacific Ocean. 3.2.12.3 Impact & Vulnerability Impacts of a tsunami vary depending on the size of the occurrence and can vary from minor damage to coastal infrastructure to complete destruction of everything in its path including buildings and severe land erosion. Tsunamis Town of Barnstable (233963.00) 3-48 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 can also impact human life and cause long term social and economic impacts depending on how much damage they cause. While not common, tsunamis are possible in the Atlantic Ocean and the Massachusetts Hazard Mitigation Plan notes that all of the coastal areas of the state are exposed to the threat of a tsunami event which could occur from a local offshore earthquake or from a major earthquake across the Atlantic Ocean. 3.2.12.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. The probability of future tsunamis in Barnstable is unlikely. The likelihood of damaging tsunami along the Massachusetts coastline is low compared to other hazards; however, the impacts could be very high. According to Boston College research, the most probable cause of a tsunami on the East Coast could be from eruptions or underwater landslides of volcanic islands on the other side of the Atlantic Ocean, such as the Canary Islands. Historical frequency of tsunamis on the East Coast is approximately one event every 39 years, based on data from 1668-2017. 3.2.13 Extreme Temperatures Extreme temperatures include both cold and hot events, which can have significant effects on human health, commercial businesses and primary or secondary impacts on infrastructure. An extreme cold event is recognized when temperatures drop below normal and increased wind speeds can cause harmful wind-chill factors. Wind Chill Advisories are issued if wind chill is forecasted to dip below -15*F for at least three hours. An extreme heat event for Massachusetts is defined as three or more days above 90*F. 3.2.13.1 Hazard Location The National Oceanic and Atmospheric Administration (NOAA) has identified 359 climate divisions nationwide, which typically coincide with county lines. Massachusetts has been divided into three regions; Barnstable is located in Region 3 as shown in Figure 24. Figure 24: NOAA’s Massachusetts Climate Regions Source: 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan Extreme temperatures can occur anywhere in Massachusetts. Colder temperatures are most common in higher elevations. Even though coastal areas may also have lower daily temperatures, they do not typically sustain them for as great an amount of time. Inland urban areas are more prone to extreme heat events due to the increased population, dark colored infrastructure and limited vegetation. Town of Barnstable (233963.00) 3-49 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 3.2.13.2 Previous Occurrences, Severity & Extent According to FEMA, there has never been a Presidential Disaster Declaration made for an extreme temperature event in the State of Massachusetts. The NCDC Storm Events Database listed the following as extreme temperature events in Barnstable County: February 4, 2016 – Extremely cold wind chills impacted New England and wind chills as low as 32 below zero were reported in Falmouth and Hyannis. Additional extreme temperature events were highlighted in the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan. Since 1994, there have been 33 cold weather events and 43 warm-weather events. Over the last two decades, an average of 1.5 extreme cold weather events (below 0 degrees Fahrenheit with wind chill) and an average of 2 extreme hot weather events (over 90 degrees Fahrenheit) have occurred in the state annually. The severity of extreme cold temperatures is generally measured using NOAA’s National Weather Service (NWS) Wind Chill Temperature Index provided in Figure 25. The index uses advances in science, technology, and computer modeling to provide an accurate, understandable and useful formula for calculating the dangers from winter winds and freezing temperatures. Extreme cold temperatures are characterized by the air temperature dropping to approximately 0 degrees Fahrenheit or below. Figure 25: NOAA’s National Weather Service Wind Chill Chart The severity of extreme heat temperatures is generally measured using NOAA’s NWS Heat Index. The Heat Index provided as Figure 26 assigns indices of caution, extreme caution, danger, and extreme danger based on relative humidity and temperatures. The Heat Index is derived for shady, light wind conditions. Exposure to full sunshine can increase the index values by up to 15 degrees.

According to the National Weather Service, in 2013, cold weather events resulted in 24 fatalities with an average of 27 cases from 2004 to 2013. In the same year, there were 92 heat-related fatalities with 123 average cases from 2004 to 2013. The most prominent impact of extreme temperatures is on human health. The Centers for Disease Control and Prevention (CDC) identified populations most at risk from extreme cold or heat to include the following: the elderly, infants and children under four years of age, individuals who are physically ill, low-income persons who cannot afford proper heating or cooling, and the general public who may overexert themselves during times of extreme heat or experience hypothermia during extreme cold events. 1 In Barnstable, according to the 2010 US Census, 21% of the population is age 65 and older while 4.6% is five years old or younger. Extreme high temperatures have also resulted in power failures due to high demand for air conditioning. During extended power outages, the lack of refrigeration results in food spoilage, transportation problems, closure of schools and businesses, and places the sick at greater risk. Extended power failures associated with blackouts can result in significant property damage. 3.2.13.4 Probability of Future Occurrence According to the 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, the probability of future occurrences is defined by the number of events over a specified period of time. For the purpose of this plan, the probability of future extreme temperature events in Barnstable is likely. The CDC indicates that climate change will result in longer, more severe, and more frequent extreme temperature events. Studies have shown that by the end of the century, the number of days with temperatures reaching 100 degrees Fahrenheit or more is projected to increase 1 2018 Massachusetts Integrated State Hazard Mitigation and Climate Adaptation Plan, website: https://www.mass.gov/files/documents/2018/09/17/SHMCAP-September2018-Chapter4.pdf Town of Barnstable (233963.00) 3-51 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 dramatically in the United States. Climate change is predicted to increase the frequency and intensity of heat waves, with significant increases in heat-related deaths. 3.2.14 Sea Level Rise Sea level rise is the increase in mean sea level over time. During the last century, tide gauges and satellites recorded measurements that indicate an acceleration of sea level rise relative to the past rate globally, including Cape Cod. Relative sea level rise refers to the combination of eustatic, isostatic, and other effects at a specific location. Eustatic contributions to sea level rise are global‐scale changes and include thermal expansion of seawater as it warms and the addition of water volume from melting land‐based glacial ice sheets. Isostatic effects are more localized changes in land surface elevations (e.g., subsidence or sinking) 3.2.14.1 Hazard Location Resilient MA Climate Change Clearinghouse for the Commonwealth provides sea level rise projections under a range of scenarios. The intermediate-high scenario projects 1.7’ by 2050 and 5.1’ by 2100. The high emission scenario projects 2.4’ of sea level rise by 2050 and 7.7’ by 2100 for Barnstable (see Figure 27). While the “bathtub” or still-water models of sea level rise provide estimations for salt-water inundation over a broad area, continually changing factors such as groundwater depth and geomorphology ought to be looked at when considering sea level impacts in a specific area. A community wide sea level rise map is included in Appendix B. Figure 27: Sea Level Rise Inundation – Long Term Scenario 3.2.14.2 Previous Occurrences, Severity & Extent Contributing to the severity of coastal storms is climate change and sea level rise which increase the volume of water in the ocean from melting ice sheets and glaciers. According to a report by the Massachusetts Office of Coastal Zone Management (CZM) the relative sea level has risen approximately 9 inches during the 20th century. A sea level rise of two feet will eliminate an estimated 10,000 square miles of land, including up to 43% of the country’s current wetlands. Town of Barnstable (233963.00) 3-52 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 The Intergovernmental Panel on Climate Change (IPCC) has predicted that sea level rise and the risks that it poses to the shoreline communities will continue to accelerate. Cape Cod and the Mid-Atlantic will likely be disproportionately affected, as threats of sea level rise are accompanied by observed subsidence of coastal land. 3.2.14.3 Impact & Vulnerability In Barnstable, sea level rise will have a direct and indirect impact. One reason is that there will be an increased risk of flooding inland is due to sea level rise reducing the ability of rivers and streams to absorb water during precipitation events and potentially raising groundwater levels. A high groundwater level limits the capacity of water bodies and natural resource areas to absorb water during a storm event which can cause more severe inland flooding. Additional development in Barnstable could also contribute to the problem by increasing stormwater runoff and eliminating open spaces that may serve as natural water storage areas for excess precipitation. Salt-water intrusion of estuarine habitats poses a threat to native species and their ecosystems, as well as fresh-water resources for drinking water. The increasing sea level will increasingly impact homes, businesses, roads, utilities, infrastructure, wastewater treatment plants, and natural habits. These impacts are already evident in Millway and adjacent neighborhoods where beach access stairs are submerged during king tides. In time, the temporarily inaccessible roads and power outages experienced during storms will become the constant norm in increasingly widespread areas of Barnstable County. Storm surges will inundate increasingly larger areas and will occur more frequently. Elderly, disabled, and impoverished residents along the coast will be the most sensitive to the impacts of sea level rise due to a disproportionate lack of adaptive capacity and resources. However, all coastal residents will be impacted to some degree. The adverse effects of rising waters are evidenced by the submersion of low-lying lands, erosion of beaches, conversion of wetlands to open water, and exacerbated coastal flooding. Rising seas can inundate coastal areas, increase storm-surge flooding, erode shorelines, and increase the salinity of estuaries and aquifers. A report by the EPA entitled “Coastal Sensitivity to Sea Level Rise” highlights the increased flooding risks associated with sea-level rise: “Rising sea level increases the vulnerability of coastal areas to flooding because higher sea level increases the frequency of floods by providing a higher base for flooding to build upon. Erosion of the shoreline could also make flooding more likely because erosion removes dunes and other natural protections against storm waves. Higher sea level also raises groundwater levels, which can increase basement flooding and increase standing water. Both the higher groundwater tables and higher surface water levels can slow the rate at which areas drain, and thereby increase the flooding from rainstorms.” A major challenge for Barnstable in the future will be evaluating the ecological and social impacts of sea level rise and developing planning and adaption strategies that will address both environmental and human interests. 3.2.14.4 Probability of Future Occurrence The 2020 MIT Joint Program on the Science and Policy of Global Climate Change indicates that sea level rise is expected to significantly increase flood risks along both the north and south shores of town. Higher sea levels will also mean higher storm surges during severe weather events. In high and low emission scenarios, the projections show ongoing sea level rise throughout the century. For long term planning purposes, sea level in Barnstable has the potential to rise by 7.7 feet in the high emission scenario. The probability of future sea level rise in Barnstable is highly likely. 3.2.15 Climate Change Climate is defined as average temperature and precipitation and includes the type, frequency, and intensity of weather events. At the local, regional and state level, climate change will alter the number and severity of extreme weather events, particularly those associated with high winds and precipitation. Understanding the impacts to infrastructure, Town of Barnstable (233963.00) 3-53 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 environment and human life is critical to developing a full picture of what climate change impacts will be. In general, the earth’s average temperature has risen by 1.5 degrees Fahrenheit in the past 100 years, and it is expected to continue that trend. In 2014, Barnstable worked with the MIT Collaborative Consensus Building Institute on a summary Climate Change Risk Assessment for the community. The report acknowledges Barnstable faces a number of climate related risks, some of which include increased occurrences of flooding, more intense coastal storms and more extreme and frequent precipitation events. These climate changes will have a direct impact on the local population, buildings, infrastructure and natural resources. The report indicates the following climate projections for Barnstable, they include: Hotter Annual Temperatures – The average annual maximum temperatures could increase between 2.9- and 6.4-degrees Fahrenheit More Extreme Heat Events, Less Extreme Cold Events – Barnstable historically experienced on average 2 extreme heat events per year (when temperatures rise above 90 degrees Fahrenheit), long term projections indicate Barnstable may see as many as 27 extreme heat events per day under high emission scenarios. Barnstable may experience between 20-40 fewer annual extreme cold events which is far below the historic average of 103 events per year. More Annual Precipitation – Barnstable may see as much as 2.8 additional inches of annual precipitation per year. More Extreme Precipitation – In the past, Barnstable has experienced an average of 1.8 events per decade where 4 inches of precipitation were present in 48 hours. Under the high emissions scenario, Barnstable could see as many as 4.1 events per decade. Wetter Winters, Drier Summers – Under the high emissions scenario, Barnstable may see up to 2.2 inches of precipitation during the winter. According to the MIT report, major risks for Barnstable include: Flooding – Coastal and inland flood hazard risk will increase which is a concern because flooding is already one of the predominant natural hazards in the community and region. Drought – With a reduction in precipitation and higher temperatures possible due to climate change, drought could cause water supply shortages or water quality issues in Barnstable as well as increase the risk of wildfires. Tourism & Economic Conditions – Barnstable relies on a strong tourism economy. Longer summers and warmer winters may offer the opportunity to extend the season for residents and visitors. The potential downside to climate change impacts are impacts climate change may have on the local beaches and natural resource areas which would limit the public’s ability to enjoy these areas. Barnstable has residential homes and commercial properties in floodplain areas (including coastal) vulnerable to flooding and sea level rise. As a part of the residential tax base, any damage to these properties could impact the tax base. Ecosystem Change – Barnstable is home to an abundance of natural resource areas including coastal habitats, freshwater wetlands and a designated Area of Critical Environmental Concern (ACEC). These areas will be impacted by climate change when sea level rise inundates coastal habitats and freshwater wetlands, threatening the plant and animal species that live there and impacting water quality.

VULNERABILITY ASSESSMENT Vulnerability refers to the susceptibility of the Town’s residents, infrastructure and natural, cultural, and historic resources to hazard events. Vulnerability indicates what is likely to be damaged by a hazard and how severe the damage might be. The vulnerability assessment conducted for the Town of Barnstable includes a profile of the Town’s existing development patterns and natural environment. Critical facilities such as hospitals, public safety facilities, and schools are identified, mapped, and surveyed for potential vulnerability. GIS analysis was used to assess vulnerability of existing structures to flooding and estimates potential dollar losses. Finally, a review of the Town’s participation in the National Flood Insurance Program is included. 4.1 COMMUNITY PROFILE The Town of Barnstable is located in Barnstable County in Cape Cod, Massachusetts. The total land area of the Town is approximately 40,000 acres. Barnstable is one of the most urbanized towns on the Cape and is a regional center of administrative and commercial activity. Hyannis Village functions as a regional commercial center and Barnstable Village is the Barnstable County seat. Originally founded in 1639, the Town contains numerous historic resources; there are more than 40 known Native American archaeological sites, 14 national historic districts, two local historic districts, and an additional 74 individually designated sites. The town’s coastal location, wetland habitats, and forested open spaces collectively create a high susceptibility to natural hazards. Specific information assembled by the Town’s GIS Department is provided below: Population 228,996 (2020 census) Acres of Developed Land 11,812 Acres of Conservation Land 9,922 Miles of Coastline 104 (saltwater), 76 (freshwater) Centerline Miles of Roads 542 (303 public, 239 private) Acres of Open Water 7,197 (including inland bays), 2,971 (excluding inland bays) Number of Great Ponds 13 Acres of Forested Woodland 17,653 Acres of Salt Marsh 3,946 Acres of Fresh Marsh 864 Acres of Cranberry Bogs 864 Acres of Shrub Swamp 434 Acres of Barrier Beach/Dunes 1,776 Acres in Hurricane Surge Zones 9,834 Acres in Flood Zones 15,240 Hazardous Waste Sites 10 Critical Facilities 109 Repetitive Loss Properties [insert current data] Town of Barnstable (233963.00) 4-2 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 4.2 CRITICAL FACILITIES INVENTORY A critical facilities inventory was compiled for the Town of Barnstable. Critical facilities identified within the Town of Barnstable include: Emergency Facilities/Shelters Public Safety Services Hospitals Town Government Facilities Wastewater Infrastructure Transportation Facilities Hazardous Material Facilities Schools Nursing Homes/Elderly Housing Group Day Care Facilities Senior/Youth/Recreation Facilities Designated Emergency Animal Shelters Marinas/Boat Yards The critical facilities inventory is represented on the Critical Facilities Map in Appendix B.

The regional facilities are the American Red Cross, the Barnstable County Complex, Cape Cod Hospital, Barnstable Municipal Airport, Cape Cod Community College, the Barnstable County Fire and Rescue Training Academy, the Humane Society, and the MSPCA Animal Shelter. 4.3 HURRICANE SURGE INUNDATION AREAS Hurricane Surge Inundation Areas, also known as Sea, Lake, and Overland Surges from Hurricanes (SLOSH) zones, are based on a computer model designed by the National Weather Service to forecast storm surges and potential flooding from hurricanes that may make landfall in New England. Surge limits shown on the community maps represent potential flooding that may occur from critical combinations of hurricane track direction, forward speed, landfall location, and high astronomical tide. The Town of Barnstable has approximately 15 square miles (9,834 acres) of property in Hurricane Inundation zones. In addition, critical facilities located in Hurricane Inundation zones are represented on the Risk Assessment and Vulnerability Map and as follows: Data: Town of Barnstable GIS # of Critical Facilities in Hurricane Zone # of Critical Facilities in Flood Zones Total # of Critical Facilities Regional Critical Facilities in Hurricane Zone Total # of Regional Critical Facilities 27 23 109 2 1 Town of Barnstable (233963.00) 4-3 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 23 Cape Cod Hospital, Hyannis (Regional) 31 Barnstable Housing Authority, Hyannis 47 Pope John Paul II High School, Hyannis 71 Hyannis Head Start, Hyannis 83 Humane Society of the US, Barnstable 86 Anchor and Marine Ltd, Hyannis 87 Barnstable Harbor Marina, Barnstable 88 Barnstable Marine Service, Barnstable* 89 Bismore Park Marina, Hyannis 90 Crosby Yacht Yard, Osterville* 91 Gateway Marina, Hyannis 92 Hyannis Marine, Hyannis* 95 Millway Marina, Barnstable 96 Nauticus Marina, Osterville 97 Oyster Harbors Marine, Osterville 98 Sandy Neck Gatehouse, West Barnstable 99 West Bay (Oyster Harbors) Bridge, Osterville 100 Harbormaster’s Building and Visitors Center, Hyannis 101 South Street Pump Station 102 Mill Way Pump Station 103 Steamship Authority, Hyannis 104 Lewis Bay Boat Ramp, Hyannis 105 Blish Point Boat Ramp, Barnstable 106 Bay Shore Road/Old Harbor Road Boat Ramp 4.4 WILDFIRE HAZARDS AREAS A significant percentage of the Town’s total acreage is identified as a wildfire hazard area. Wildfire hazard areas are defined as unfragmented forest habitat greater than 40 acres in size or salt marsh areas greater than three acres in size. There are 13 Critical Facilities located in wildfire hazard areas or in wildfire/urban interface zones in the Town of Barnstable. 12 Osterville Elementary 26 Barnstable Water Department at 1841 Phinney’s Lane 29 Cotuit Water Department 33 Hyannis Water Department 38 Town Offices – Marine and Environmental Affairs at 1189 Phinney’s Lane 45 Cape Cod Academy 52 Cape Cod Community College 62 Bright Promises Preschool 64 Cape Cod Conservatory Preschool 78 West Parish Family School 82 Bayview Kennels 83 Humane Society of the U.S. 85 Special K Kennels Town of Barnstable (233963.00) 4-4 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 4.5 FLOOD ZONES – VULNERABILITY ANALYSIS [TO BE UPDATED] To assess the vulnerability of the Town’s built environment to flood hazards, an analysis of the structures and land uses in FEMA flood zones was conducted by the Town’s GIS Department1. The following table summarizes that analysis; the table represents the number of parcels located in FEMA A and V flood zones, building square footage, and assessed building values. The vulnerability analysis was conducted using the [update] FEMA Flood Insurance Rate Maps. Although these maps were not officially adopted by the Town at the time of the analysis, they provided the opportunity for the most accurate analysis.

Town of Barnstable (233963.00) 4-5 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 As expected, residential properties are the most vulnerable to flood damage in terms of numbers, square footage, and assessed value; 1,114 housing units totaling over $425.9 million in value are located in flood hazard areas. Potential commercial losses from flooding total over $38 million, not including commercial enterprises that might be included in the mixed-use category. Many of these uses are likely marine-related businesses that rely on having good access to the water. A closer evaluation of the locations and functions of these commercial properties would be valuable and facilitate efforts to minimize economic losses after major flood events. The Village of Hyannis has the greatest number of structures vulnerable to flood damage; many of these structures are located around the Inner Harbor, Lewis Bay, Hyannis Harbor, and Stewart’s Creek. The Village of Osterville faces the greatest potential dollar losses from flooding. The average assessed value of a structure in the flood zone in Osterville is almost $800,000. This data reflects the vulnerability of high dollar homes located on Vineyard Sound and the Three Bays. The Village of Centerville also has a high number of structures vulnerable to flooding; these properties are located primarily around the Centerville Harbor and Centerville River. In addition to concerns regarding vulnerability of structures, the MHM Planning Team identified several roads that are prone to flooding. Flooding of these roadways could potentially interfere with travel of emergency vehicles and evacuation of residents. The following areas are of concern: Route 6 in Barnstable (evacuation route) Mill Way in Barnstable Commerce Road in Barnstable West Bay (Oyster Harbors) Bridge (also vulnerable to wind hazards) 4.6 NATIONAL FLOOD INSURANCE PROGRAM AND REPETITIVE LOSS PROPERTIES The Town of Barnstable participates in the National Flood Insurance Program (NFIP). The most recently available data associated with NFIP is dated March 2010. As of March 31, 2010, the town had 1,065 NFIP policies in force, totaling $288,793,300 of coverage. Between 2002 and 2010, the number of policies held in Barnstable increased by 123, increasing the total coverage amount in force by $106,065,100. From the inception of NFIP in 1972 to March 31, 2010, 277 loss claims were filed in the Town; 115 of those claims were paid totaling $2,901,868. Repetitive loss properties have been paid two or more claims by the NFIP worth at least $1,000 each over a ten-year rolling period. The Town of Barnstable has 27 repetitive loss properties, which is a significant increase from the 17 repetitive loss properties present in 2010. The properties are located in Cape Cod Bay near Barnstable Harbor, on Nantucket Sound with a concentration on Centerville Harbor, and in the Village of Hyannis, near the intersection of Route 28 and Bearse’s Way. Some of the repetitive loss properties are located in “A” zones and one in a “V” zone. One property has 5 paid loss claims (a non-residential property), one has 4, and two have three paid loss claims. The areas where repetitive loss properties are located are shown on the Risk and Vulnerability Assessment Map. Barnstable’s floodplains are managed through zoning, wetlands, and health regulations. The Local Capital Improvement Plan outlined undersized culverts that will be improved upon to reduce flooding. The Town also regularly completes significant catch basin cleaning in flood prone areas. Any new construction in flood areas is managed through the newly adopted Floodplain bylaws and are reviewed by the Conservation Commission. The Town is committed to the ongoing enforcement of these regulations and will continue to review and enhance requirements to best protect the environment and vulnerable properties. Additionally, the Town is engaged in public outreach programs to promote private floodplain management best practices and continued participation in the NFIP. Town of Barnstable (233963.00) 4-6 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 community development The maps in Appendix B show flood zones and sea level rise projections for the Town. Due to the coastal nature of the community, coastal areas are those most impacted by flooding. Approximately 20% of the critical facilities are located in flood zones and are carefully managed to reduce vulnerabilities to the extent possible. Sine the 2010 Hazard Mitigation Plan was developed, there have been no significant increases in development in these areas for critical facilities or in general. In addition, there are no current plans for significant future development in hazard areas. The Town recently updated its floodplain bylaw which requires any new development in the floodplain to have a review by the Conservation Commission and approval under the Wetlands Protection Act. Overall, Barnstable’s potential future development would not significantly increase the Town’s vulnerability if existing regulations are adhered to. The Town is also actively, studying low lying roads, will assist in prioritizing areas to consider for further reduced development and improve infrastructure. 4.7 COMMUNITY DEVELOPMENT The maps in Appendix B show flood zones and sea level rise projections for the Town.

The Town is also actively, studying low lying roads, will assist in prioritizing areas to consider for further reduced development and improve infrastructure. 4.8 FUTURE PLANNING This Hazard Mitigation Plan update will be incorporated into future planning mechanisms as applicable, most immediately the low-lying roads work and the upcoming Comprehensive Plan update. The update will inform and work in conjunction with the low-lying roads initiative to identify and prioritize areas to consider for further reduced development and areas in need of infrastructure improvements. The update will also be used to provide valuable insights to the Comprehensive Plan that will target potential areas for development and planning around critical facilities and community needs. The update will continue to be a tool to support the Local Capital Improvement Plan that identifies culverts to be upsized to address flooding. As always, we will rely on the update to inform emergency management and hazard mitigation and response. 942 1,065 NFIP Policies in Force 2010 2002 $182,728,200 $288,793,300 NFIP Coverage Amount in Force 2010 2002 Town of Barnstable (233963.00) 5-1 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 5. MITIGATION ACTIONS This section describes the mitigation actions identified to contribute to the Town of Barnstable’s resiliency and the capabilities available within the Town to implement the mitigation actions. The capabilities reside in Town leaders that are committed to resiliency and strong partnerships that support regional hazard mitigation planning efforts. The mitigation actions identified area intended to be comprehensive and far reaching to address the identified Town goals and objectives. 5.1 CAPABILITIES ASSESSMENT Barnstable’s commitment to hazard mitigation has been reinvigorated since the development of the 2010 plan based on new resources available within the Town departments and a strong commitment to support the community’s resilience. Barnstable recognizes its coastal location presents added challenges for resilience. Barnstable has strong capabilities, such as plans, policies, staff, funding and other related resources, to continue to work toward resiliency. These existing capabilities, as well as opportunities to expand or improve these capabilities, are described below. 5.1.1 Plans and Policies Barnstable has a variety of planning documents and policies that address natural hazards. These documents incorporate aspects of Barnstable’s hazard mitigation plan goals and mitigation strategies. As Barnstable continues to implement these plans and policies, resiliency will be advanced and vulnerabilities will be reduced. These plans and policies include: Local Comprehensive Plan (2010, update in process) – The Plan describes actions and strategies the Town should implement to attain a better balance between land use and community resources and to ensure a sustainable future. This plan also refocuses on the need to direct growth to designated areas, protect and reconnect sensitive habitat areas, protect and improve drinking water, fresh water and coastal water quality, manage traffic to improve congestion and preserve heritage and community character. A major emphasis of this plan is implementation, the specific actions to be taken to turn the visions of this plan into a reality for a sustainable future. As part of the current update, Barnstable’s hazard mitigation strategies will be incorporated and advanced. Comprehensive Wastewater Management Plan (CWMP) (2020) - The CWMP addresses various wastewater related issues within the community. The primary focus is nutrient removal, particularly nitrogen removal, as nitrogen has been shown to be causing eutrophication in coastal embayments. The prevalence of nitrogen has become an issue due to the widespread reliance on on-site septic systems as a means of addressing wastewater. The Plan also addresses nutrient contamination of ponds and Contaminants of Emerging Concern which have been affecting drinking water sources within the community. Open Space and Recreation Plan (2018) – The purpose of the Plan is to guide the Town’s plans, investments, policies and regulations in support of protecting and enhancing open space and recreation resources. Specific goals are to: Protect and maintain a maximum amount of open space to enhance environmental protection, recreational opportunities and community character; use land protection to protect water supply, protect fresh and marine surface waters, preserve historic, scenic and cultural resources, and provide opportunities for farming and agriculture; provide diverse recreational opportunities and access throughout Barnstable and ensure that the current and future needs of all user groups are met appropriately; provide adequate public access to and safe enjoyment of the Town’s open space and recreational resources and programs, particularly its fresh and marine shoreline areas, and promote greater coordination and communication about community open space and recreation needs within government and among stakeholder groups in the Town. Town of Barnstable (233963.00) 5-2 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Town of Barnstable Comprehensive Emergency Management Plan (CEMP) (2020) – The CEMP provides a framework for community-wide emergency management and pre-planning for designated events. The plan is designed to support the welfare and safety of the community during times of disaster and series emergencies. Disaster events can take a variety of forms, including natural disasters. The plan outlines the roles and responsibilities of various departments and resources needed in times of emergencies. EPA’s MS4 Stormwater Bylaws. Barnstable follows the requirements outlined in the MS4 bylaws that include pollution prevention measures, treatment or removal techniques, monitoring, use of legal authority, and other appropriate measures to control the quality of storm water discharged to the storm drains and waters of the United States. Town of Barnstable Zoning Ordinance. The Zoning ordinance promotes the health, safety, convenience, morals and general welfare of the inhabitants of the Town, protects and conserves the value of the property within the Town, increases the amenities of the Town, and secures safety from seasonal or periodic flooding, fire, congestion or confusion, all in accord with the General Laws, Chapter 40A, as amended. The Floodplain ordinance was recently updated and adopted this year. Municipal Vulnerability Preparedness (MVP) Program Plan (2020) – The MVP plan identifies vulnerabilities from natural hazards and climate change and developed actions to mitigate the hazards. The process resulted in Barnstable becoming an MVP certified community. These plans provide a strong foundation to continue to advance hazard mitigation planning and address challenges specific to Barnstable including flooding, coastal erosion, sea level rise and climate change. Future planning documents can continue to be more specific regarding means to address the highest ranked natural hazards identified in this plan, means to achieve identified hazard mitigation goals, and specific mitigation measures. The proposed mitigation actions outlined in Sections 5.2 and 5.3 provide specific and actionable recommendations which will help toward a current and focused approach to hazard mitigation. Many of the existing Town policies and ordinances provide further support to mitigate hazards. Barnstable follows the Massachusetts state building code to ensure new buildings and structures incorporate hazard preparedness. Specifically, Barnstable has a floodplain district that includes all special flood hazard areas within the Town designated as Zone AE, AO, or VE on the Barnstable County Flood Insurance Rate Map (FIRM) issued by FEMA for the administration of the NFIP. There are also groundwater protection overlay districts to protect the public health, safety, and welfare by encouraging nonhazardous, compatible land uses within groundwater recharge areas. For both he floodplain and groundwater protection districts, special provisions are outlined for each to ensure appropriate protections. As Barnstable continues to advance its mitigation planning efforts, these codes and bylaws could be further enhanced for greater hazard mitigation. 5.1.2 Financial Capabilities While Barnstable continues to strive to identify and establish funding mechanisms to implement mitigation actions, there are existing mechanisms in place that have and will continue to be used to advance Barnstable’s hazard mitigation goals. Barnstable has the following potential funding sources to implement hazard mitigation actions: FY 2022 Capital Budget and FY 2022 – 2026 Capital Improvement Plan – The Town Administration has implemented a review process for capital submissions requesting financing that scores projects twice and then averages the rank from each process to determine an overall ranking. The highest priority ranking addresses public health and safety risks or alleviates an emergency service disruption. Fees from water and sewer services – A percentage of water and sewer fees are dedicated to upgrading infrastructure that will assist in reducing vulnerabilities. Town of Barnstable (233963.00) 5-3 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Incurring debt through general obligation bonds – Barnstable routinely bonds for large infrastructure improvement projects to reduce vulnerabilities. Community Preservation Act Funding – A percentage of the Community Preservation Act funding is used to preserve open space to limit development. While Barnstable can independently fund some mitigation actions, other outside funding will be necessary to advance all of Barnstable’s mitigation actions. In 2018, Barnstable received a grant from the Massachusetts Executive Office of Energy and Environmental Affairs Municipal Vulnerability Preparedness (MVP) Program to identify vulnerabilities from natural hazards and climate change and develop actions to mitigate the hazards. Barnstable has also received funding from the Massachusetts Coastal Zone Management (CZM) program for the Fiscal Year 2022 Coast Pollutant Remediation Grant. Additional grant funding will be required to implement the mitigation actions outlined in Sections 5.2 and 5.3, especially for the project requiring larger funding allocations. Table 5-5 identified possible funding sources that could be accessed, and Table 5-2 matches those funding sources with the identified mitigation actions. 5.1.3 Department Staffing Barnstable has various departmental and staffing resources to help implement the goals and actions outlines in this plan. In addition, Barnstable is committed to adding a Certified Floodplain Manager to its existing capabilities. Specific departmental and regional capabilities are discussed below. Planning & Development The Town of Barnstable has a strong Planning & Development department and committed Director that has spearheaded this planning effort. Recent staff additions have included a Senior Planner that has experience in hazard mitigation planning, having led this effort at a previous municipality. Planning & Development also led the charge for the 2019 Municipal Vulnerability Planning effort and became designated as a MVP community. The department is also in the process of updating its 2010 Local Comprehensive Plan, with climate change as being one of the major drivers for the update. These efforts demonstrate the department’s commitment to resiliency and its willingness to dedicate resources toward this effort. Marine and Environmental Affairs The Marine and Environmental Affairs Department strives to protect and preserve the Town’s waterways and natural resources. Natural Resource officers patrol town conservation areas and beaches to enforce local by-laws and state and federal wildlife, fisheries, and environmental regulations. The program provides support for over sand operations at Sandy Neck, including environmental functions associated with endangered species and resource management. The Harbormaster is also very focused on community education associated with storm events. These resources are important in Barnstable’s overall climate resiliency efforts. Public Works The Barnstable Department of Public Works mission is to preserve and improve the Town's infrastructure and related assets in a manner which meets and enhances the current and future social and economic needs of the community, to contribute to a healthy, safe, and quality environment for the town's citizens and visitors, and to provide a cost effective and environmentally sound means of disposing of solid waste and wastewater. Public Works is very involved in wastewater and clean water management and recycling. They are focused on driving resiliency in the Town’s infrastructure. Police and Fire Departments The Barnstable Police and Fire are very active partners in the path toward resilience. The department utilize CodeRED as its emergency notification service by which town officials can notify Barnstable residents and businesses by Town of Barnstable (233963.00) 5-4 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 telephone, cellular phone, text message, or electronic mail about time‐sensitive emergency situations or important community alerts.

Implementation of projects and mitigation activities were prioritized by a qualitative ranking of high, medium or low. STAPLEE criteria was applied to the extent possible to all of the projects and mitigation activities that have been identified in the Hazard Mitigation Plan and priorities were evaluated based on need, cost-effectiveness, number of hazards addressed, number of objectives met and funding eligibility. Town of Barnstable (233963.00) 5-25 Woodard & Curran 2022 Hazard Mitigation Plan Update June 2022 Barnstable utilized a qualitative assessment (high, medium, low) for prioritizing projects and mitigation activities for this plan. · High Priority – Denotes a project or mitigation activity that meets multiple plan objectives, addresses multiple hazards, has benefits that outweigh potential costs, has funding secured or is able to be funded through the municipal budget and may be eligible for grant funding. Projects of high priority have the potential to be completed within the next 5 years. · Medium Priority – Denotes a project or mitigation activity that meets some goals and objectives, addresses some hazards, has benefits that outweigh potential costs, funding is not in place but could be through municipal allocation or grant funding. · Low Priority – Denotes a project that meets at least one goal/objective, addresses at least on hazard, costs may outweigh the benefits, funding has not been secured and grant eligibility is unclear and the timeframe for completion is probably long term. Plan implementation will focus on the projects and mitigation activities that have the highest level priority associated with them. Over time and as the plan is implemented, priorities may change due to new funding sources, information or future hazard events. During the annual review of this Plan there will be a specific review of the list of projects and mitigation activities to make sure that the prioritization ranking for each one is still the most appropriate. Table 5-4 indicates the project number, responsible party and whether or not the project meets each individual STAPLEE criteria at a high, medium or low level. After taking this information into consideration, each project was given a qualitative high, medium or low ranking.

The HMP team, led by the Planning and Development department, will also evaluate the Plan after disaster events to examine the effectiveness of mitigation strategies and the impact of disasters on critical facilities and other infrastructure. An additional evaluation will be initiated if any funding opportunities are introduced. If necessary, recommendations for revisions or amendments should be made in response to the evaluation. Any revisions or amendments made to the Plan should be done with the approval of the Town Council. Proposed amendments should be distributed to all relevant Town Departments and other interested parties for review. The public should be made aware of pending changes through traditional channels and an open review and comment period should be established. Proposed and adopted amendments should be sent to the Cape Cod Commission and to MEMA. The HMP team, led by the Planning and Development department, will also evaluate the Plan and prepare an update at least every five years in accordance with FEMA requirements under 44 CFR § 201.6(d)(3) and MEMA and FEMA program requirements. This is essential in order to continue eligibility for FEMA hazard mitigation project grant funding. The HMP team, led by the Planning and Development department, will reconvene to reevaluate the Town’s risks and vulnerabilities. The team will evaluate new development patterns, increased exposure to risk, advances in mitigation capabilities or techniques, or changes in Federal, State, or County legislation. An analysis of the plan mitigation strategy and action items will be conducted to ensure all measures are appropriate. This plan will be made available to the public on the Town of Barnstable’s website. 6.2 LOCAL ADOPTION Once the 2022 HMP update is determined to be Approved Pending Adoption (APA) by FEMA, the proposed mitigation approach will be put into action and the plan will be adopted. Adoption must occur within one calendar of FEMA’s approval. Plan implementation progress will be contingent on the availability of staff and funding towards mitigation. On [date] the Barnstable Town Council voted to pass a resolution adopting the 2022 Barnstable Hazard Mitigation Plan as presented (Appendix C).

March 15, 2022 Sarah White Massachusetts Emergency Management Agency 400 Worcester Road Framingham, Massachusetts 02114 On behalf of the Town of Barnstable Planning Board, I would like to express our support for the Town of Barnstable (Barnstable) 2022 Hazard Mitigation Plan Update and recommend its approval by the Federal Emergency Management Agency and Massachusetts Emergency Management Agency. We believe the Barnstable 2022 Hazard Mitigation Plan Update acknowledges the town’s risk and vulnerability to potential natural hazards and to build upon the resiliency efforts by identifying key mitigation strategies and actions aimed at reducing the loss of or damage to life, property, infrastructure and natural, cultural, and economic resources. The plan provides a valuable implementation strategy to guide the community in the coming years.
