2 Dummerston Town-Specific Plan INTRODUCTION AND PURPOSE This appendix, when used with the appropriate sections of the basic plan, is an All-Hazard Mitigation Plan for the town of Dummerston. The purpose of this plan is to assist the town of Dummerston in identifying all of the hazards facing the town and to identify strategies to begin reducing risks from identified hazards. Hazard mitigation is any sustained action that reduces or eliminates long-term risk to people and property from natural and human-caused hazards and their effects. Based on the results of previous Project Impact efforts, FEMA and state agencies have come to recognize that it is less expensive to prevent disasters than to repeatedly repair damage after a disaster has struck. This plan recognizes that communities have opportunities to identify mitigation strategies and measures during all of the other phases of Emergency Management preparedness, response and recovery. Hazards cannot be eliminated, but it is possible to determine what the hazards are, where the hazards are most severe and identify local actions that can be taken to reduce the severity of the hazard. Hazard mitigation strategies and measures alter the hazard by eliminating or reducing the frequency of occurrence, averting the hazard by redirecting the impact by means of a structure or land treatment, adapt to the hazard by modifying structures or standards or avoid the hazard by stopping or limiting development, and could include projects such as: Flood-proofing structures Tying down propane/fuel tanks in flood-prone areas Elevating furnaces and water heaters Identifying and modifying high traffic incident locations and routes Ensuring adequate water supply Elevating structures or utilities above flood levels Identifying and upgrading undersized culverts Proactive land use planning for floodplains and other flood-prone areas Proper road maintenance and construction Ensuring critical facilities are safely located Establish and enforce appropriate building codes Public information Local Planning Process The planning process with the Town of Dummerston began in July of The plan was submitted to FEMA Region 1 by the end of the year of 2009, with comments received by FEMA wanting to have aspects of the plan more thoroughly explained. The planning process resumed in June 2011 with a meeting where mitigation strategies were discussed in detail, and a plan of action to make public participation a part of the planning process. (See the Public Participation section.) The local planning process followed the steps listed in the Regional All-Hazard Mitigation Plan in Section 2. Work commenced with the Local Emergency Management Organization of Dummerston, acting as the local Hazard Mitigation Planning Committee. The Town of Dummerston will continue to work with the Windham Regional Commission to monitor, evaluate, and update the plan throughout the next 5 year cycle. A review of the plan will take place each year by the emergency planner at the Windham Regional Commission along with the Town s EMD and Planning Commission Chair to update any funding received from FEMA, to record any hazard related events, and to determine if the town plans to apply for grant funding. Normal review of the plan will also take active involvement on the part of both the Selectboard Chair and the Planning Commission Chair, working with Windham Regional Commission staff to Annex B Page 2

3 identify and plan for ongoing hazard mitigation work and coordination among stakeholders to identify structures and engineering projects that can help mitigate future hazardous events; e.g. bridge and culverts replacements, road replacements and grading, as well as any repetitive loss structures that may be in the Special Flood Hazard Area as identified on FEMA Flood Maps (e.g. FHBM and FIRM maps). The following hazard mitigation planning meetings were held: Dummerston Center Fire Station, July 21, 2009, 6:30pm Dummerston Center Fire Station, September 22, 2009, 6:30pm Dummerston Center Fire Station, June 20, 2011, 6:30 pm Hazard Mitigation Goals Reduce the loss of life and injury resulting from all hazards. Reduce the impact of hazards on the town s water bodies, natural resources, and historic resources. Reduce the economic impacts from hazard events. - Minimize disruption to the road network and maintain access - Mitigate financial losses incurred by municipal, residential, industrial, agricultural and commercial establishments due to disasters. - Ensure that community infrastructure is not significantly damaged by a hazard event. Encourage hazard mitigation planning to be incorporated into other community planning projects, such as the Town Plan, Capital Improvement Plan, Rapid Response Plan and Town Emergency Plan. Ensure that members of the general public continue to be part of the hazard mitigation planning process. The Hazard Mitigation Goals as outlined above where developed by consensus among the emergency management committee during meetings on the town of Dummerston local hazard mitigation plan. Acknowledgements Town residents who took part in the planning process for developing the Pre-disaster Hazard Mitigation Plan for Dummerston tend to be affiliated with more than one association for the town. In rural areas of Vermont, it is typical that people who are most interested in the safety, health and welfare of their community will preside on more than one board, as well as hold the role, for example, of Fire Chief, or school teacher, or be a small business owner, in addition to owning personal property in the town. Therefore, although the meetings may not have had as many in attendance as in a more populated community, those present at the meeting are representing not only a variety of roles, but many roles that would be held by individuals in a more populated town or city. The following people were involved in the hazard mitigation planning process: Committee Member Dawn Hubbard Lee Chamberlin Marty Forret Affiliations Emergency Management Director Highways Department Foreman Fire Chief Home Dummerston, VT Dummerston, VT Dummerston, VT Annex B Page 3

Copies of the Draft plan were made available for public review at the Town Meeting in March A link to the plan is located on the Dummerston Town website where citizens are provided the opportunity to make comment on the plan The plan was advertised in the Dummerston Views newsletter, asking town folk to come to the Town Offices, review the plan and make comment. The Windham Regional Commission also hosts a meeting every other month for the Road Foremen in the small towns within the region to discuss various issues involving roads, culverts, ditches and hazards that create negatives. Such a meeting was held October 21, At the beginning of the meeting, an introduction to the Pre-disaster Hazard Mitigation Planning process was presented by Dinah Reed with copies of town hazard plans. The purpose, planning process and grant funding that becomes available once the plan has been approved by FEMA and adopted by the Town, was explained and made aware to members of the community. The Town of Dummerston had representation at this meeting. (see attached sign-in sheet). Annex B Page 4

5 TOWN PROFILE Dummerston s Unique Sense of Place The Town of Dummerston is geographically unique in that the town is divided in two by the West River. There are only two bridges that serve as crossings between the two sides to town. Both of those bridges are historical and one lane. Presently one of those bridges, The Green Iron Bridge, is closed for reconstruction. It is determined that even after it s renovation, large vehicles, such as fire trucks and school buses, will not be able to cross this bridge. If something were to happen to the covered bridge where it is not useable, all vehicles would have to go south on either Rt. 30 or Rt. to Brattleboro and back north to reach either side of the town. Community Background Dummerston is a rural hill town of 19,200 acres or 30 square miles in southern Windham County. Dummerston is bordered to the north by Putney and Brookline, Newfane and Marlboro the West, and Brattleboro to the South. State highway 5 runs north/south through Dummerston and state highway 30 runs east/west through town. Interstate 91 also runs north/south through the eastern section of Dummerston. Dummerston s population as of 2006 was 1,952 persons. Evacuation Route and Evacuation Plans for an incident at Vermont Yankee Nuclear Power Plant are on file with the Fire Department. The physical characteristics of Dummerston are dominated by two rivers: the Connecticut River, which forms the eastern boundary of the Town, and the West River, which flows through Dummerston before joining the Connecticut River in Brattleboro. The topography of Dummerston is varied, being relatively flat in the Connecticut River Valley and quite hilly elsewhere in Town. The highest point is Dummerston Hill at an elevation of just over 1,600 feet., a dominant landmark located between the river valleys in the southern part of Town. Smaller hills include Prospect Hill, Black Mountain and Wickopee Hill. Land use in Dummerston is characterized by large rural areas in which compact settlement exists chiefly in West Dummerston, Dummerston Center, and Slab Hollow. Elsewhere homes and commercial establishments are located along rural routes in a linear pattern. Woodlands are predominant in Dummerston and cover a vast acreage of land. These forestlands provide the scenic backdrop for the Town and provide wood products, game for hunting, maple products and recreation. Most forestland is private, non-industrial ownership. Approximately 6,600 acres mostly forested are actively managed under the Vermont Current Use Value Appraisal Program. Approximately 7,885 acres both forested and farmland are conserved in Dummerston (2007 acreage data). Development Trends The 2000 Census indicates a population of 1,915 and a growth rate of 3 percent over the 1990 population. This is lower than the 8.2 percent growth rate for the State, but higher than the 5 percent growth rate for Windham County during the same period. Since 1980, Dummerston has experienced a 22 percent increase in population. As of the summer of 2009, there are no appreciably large scale residential or commercial developments slated for permitting or construction. In recent years, The Development Review Board has issued permit approvals for only a handful of projects. In 2008, there were only 7 projects approved, while two were denied and one was withdrawn. Future development is expected to be minimal. Any new single family dwellings that have been built over the past few years have been built out of the floodplain. The Town Officials are presently in the process of taking a closer look at the land capacity and suitability along the major State roads Rt. 30 and Rt. 5, to determine what the most appropriate uses are for those corridors, i.e. commercial, industrial or residential.

6 COMMUNITY HAZARD INVENTORY AND VULNERABILITY ASSESSMENT Methodology A vulnerability analysis for each community begins with an inventory of possible hazards and an assessment of the risk that they pose. These are the questions to be answered. What hazards can affect your community? How bad can it get? How likely are they to occur? What will be affected by these hazards? How will these hazards affect you? The magnitude (percentage of the community affected) of the impact of the hazard can be classed as follows: Negligible: < 10% of properties damaged/minimal disruption to quality of life. Limited: 10% to < 25% of properties damaged/loss of essential facilities/services for up to 7 days/few (< 1% of population) injuries possible. Critical: 25% to 50% of properties damaged/loss of essential facilities/services for > 7 days < 14 days/major (< 10% of population) injuries/few deaths possible. Catastrophic: > 50% of properties damaged/loss of essential facilities/services for > 14 days/severe (> 10% of population) injuries/multiple deaths possible. The frequency of occurrence (Likelihood) is classified as shown: Unlikely: < 1% probability in the next 100 years. Possible: 1% to 10% probability in the next year, or at least one chance in the next 100 years. Likely: 10% to 100% probability in the next year, or at least one chance in the next 10 years. Highly Likely: Near 100% probability in the next year. Additionally, seasonal patterns that may exist are considered, what areas are likely to be affected most, the probable duration of the hazard, the speed of onset (amount of warning time, considered with existing warning systems). The combination of the magnitude of the hazard and the frequency was used to determine the community vulnerability as HIGH, MODERATE or LOW. For example, a flood event is highly likely (nearly 100% probability in the next year) in many communities but the degree of impact varies. A highly likely flood with critical or catastrophic impact rates the community vulnerability as HIGH. Another community with a highly likely or likely (at least one chance in the next 10 years) flood with a limited impact would receive a vulnerability rating of MODERATE. The vulnerability of a community having the occurrence of an event as possible or unlikely with limited or negligible impact would be LOW. Likelihood: U = unlikely P = possible L = likely HL = highly likely Impact: N = negligible L = limited CR = critical CA = catastrophic Possible Hazard Likeli Community Most vulnerable facilities and hood Impact Vulnerability populations Tornado/Microburst U L Low Roads, Bridges, Culverts Flood (25 Year) L L Low Low lying hills, West River Corridor 100-year flood P L Moderate Low lying hills, West River Corridor Drainage Ditches, West River Flash flood L L Moderate Corridor Annex B Page 6

Flash floods typically occur during summer when a large thunderstorm or a series of rain storms result in high volumes of rain over a short period of time. Higher-elevation drainage areas and streams are particularly susceptible to flash floods. Flash floods are likely in Dummerston, and potential damage to Route 5 or Route 30 could limit access to Town, as they are the major transportation corridors through the community. Some of the highest hazard areas associated with flash floods are Dummerston and Spaulding Hills, Camp Arden Rd. and areas along the West River floodplain corridor. These areas have all seen damage in recent years with flooding and severe thunderstorms that have been a part of Presidentially declared disasters. Other areas of concerning during flooding events are homes located along the Connecticut River Valley FEMA defined floodplain, residences along or adjacent to Catherine Meadows, and the end of Dummerston Station Rd. NFIP Compliance The Town of Dummerston has a Flood Hazard Area Regulations as a stand-alone ordinance and currently participates in the National Flood Insurance Program which was updated in September The town has a Zoning Administrator who enforces the flood hazard regulations. Fluvial Erosion Hazard Zones (FEH) In acknowledgement that existing technical resources and land use guidance or regulatory authorities, such as the National Flood Insurance Program, do not adequately identify high risk areas for development along riparian corridors with respect to fluvial erosion hazards it is therefore deemed a high priority of this Hazard Mitigation Plan to provide the technical support for, and to develop and implement protection mechanisms at the local level that will serve to avoid land use investments that would be, over time, endangered by, incompatible or in conflict with fluvial adjustment and erosion processes. VT ANR is in the process of conducting fluvial geomorphic assessments on certain sections of the West River. Annex B Page 7

8 After a fluvial geomorphic assessment, the town, under contract with the Regional Planning Commission, or other GIS mapping service provider, shall develop a fluvial erosion map. Such map shall be consistent with mapping standards and protocols developed by VT ANR. Winter Storms/ Ice Storms Winter storms, with snow, ice and freezing temperatures in varying combinations, are fairly commonplace in Dummerston and occur town wide. Heavy wet snows of early fall and late spring, as well as ice storms, often result in loss of electric power, leaving people without adequate heating capability. The other threat from these storms is downed trees, resulting in power failures and impassable roads or driveways. An Ice Storm which crossed the region in December of 2008 caused widespread downed trees and power outages in Windham County, The total cost of damages across the region crossed the one million dollar threshold which allowed for a Presidential Disaster Declaration DR Damage across the region mostly consisted of road being blocked for shorts periods of time due to downed trees and utility lines. Thousands lost power for varying lengths of time and several shelters were opened in Windham County. Compared to neighboring southern New Hampshire communities, Dummerston and Windham County fared relatively well from the damage inflicted by the Ice Storm. Wildfire / Structure Fire Wildfires can spread to residential areas, thus forcing whole communities to evacuate. When fires are followed by heavy rains, the potential for mudslides and flooding is increased. Most of Dummerston is heavily forested. Hence, the potential, given the right conditions, for widespread forest fires is great. However, wildfire conditions do not occur frequently due to the relatively high annual precipitation level. Northern New England did experience some large forest fires in the late 1940s. Portions of the Vermont forest are now beyond the natural burn cycle. Communities or residents located in or along the edges of forested areas are particularly at risk. Wildland fires are most likely in the summer and fall months. Structure fires are highly likely but not common in Dummerston. Structure fires can result in loss of property and/or life. They can affect a single residential structure or spread to other homes, businesses or apartment complexes. Residential fires kill more people in the U.S. each year than all natural disasters combined. In Vermont, 12 fatal fires resulting in 22 civilian deaths occurred in The most significant common factor in fire fatalities in Vermont continues to be the absence of a functioning smoke detector in the sleeping area of residential structures. Fires can be caused by improperly disposing of ashes with live coals from wood stoves or faulty electrical wiring. Power Failure Power failure is a common event in Dummerston and can occur anywhere in town. Power failures are typically the result of power lines damaged by high winds or heavy snow/ice storms. During Ice Storms the higher elevation locations in Town are most susceptible to power failures. Sunset Lake Rd., Cemetery Rd., and Stickney Brook Rd. are areas of Town where it would be common for power line failures to occur and cause power disruptions to residential dwellings. Power failures may also result from disruptions in the New England or national power grid, as indicated by the widespread power outages in Dead or dying trees in close proximity to power lines pose a particular threat for power failure. High Wind High wind events are highly likely in Dummerston, with the potential for limited resulting damage. The mostly likely local threats for high winds are from nor easters, hurricanes, downbursts or wind shear. Trees downed by high winds can block roads, and down power and communications lines. Mobile home parks and houses on ridge lines are at greater risk from wind damage. Most high winds events in Dummerston have resulted in minor damage from downed trees and power lines. Annex B Page 8

9 Risk Assessment - Potential Loss Estimates In order to determine potential dollar losses to vulnerable structures due to natural and manmade hazards, each higher-risk hazard type was analyzed below. Human losses are not calculated during this exercise, but could be expected to occur depending on the type and severity of the hazard. Potential loss estimates are based on vulnerability and risk discussions held during Dummerston Hazard Mitigation Committee meetings. Flash floods Flash floods typically occur in high elevation drainage areas as a result of summer thunderstorm activity. Damage from flash floods is difficult to predict since, flash flood areas are not mapped at this time. Infrastructure and structures along higher elevation streams and drainage areas are most susceptible to damage from flash flooding. Drainage ditches and culverts are the biggest concern for local flash flooding events. Dummerston and Spaulding Hills have seen some of the most recent damage from springtime rain on snow events. Due to their higher elevation, flash floods can potentially cause severe flood damage in these areas of Town. There have been several Presidentially Declared Disasters in recent years for Windham County which have included severe thunderstorms and associated flooding, Windham County, including the Town of Dummerston, In 2003 nearly constant rain and thunderstorms affected Dummerston from the period of July 21 through August 18. FEMA Declaration DR 1488 was associated with this event. Many roads were washed out and culverts needed replacing throughout Town. The following year, another severe period of flooding and thunderstorms, which lasted from the period of August 12- September 12 engendered Presidential Disaster Declaration DR These two events allowed for funding from the FEMA Public Assistance Program to flow into town and help pay for embankments that were associated with a washout on Camp Arden Rd. FEMA covered 75% of the cost of repairs, giving Dummerston $150,410. The total cost of repairs on the road was just over $200,000. In 2007, another flooding event occurred which was associated with flash floods and inundation flooding over a period of several days in the spring (April 15-21). Rain and snow caused damage to roads and utility lines across Windham County and Dummerston. Across, the State, nearly 3.6 million dollars was obligated as part of the FEMA Public Assistance Program. While it is not normal for the Town to receive this type of damage from severe flooding and thunderstorms on an annual basis, road washouts and culvert repairs from these associated events have ranged in the ballpark of $200,000 to $400,000. Wildfires / Structure Fires Damage from wildfires is difficult to project. Forest fires are more likely during years of drought or during drier seasons (late summer or fall). Fire danger is generally universal and can occur practically at any time. Damage would depend upon the extent of the fire, the number and type of buildings damaged and the contents destroyed within the structures. Structure fires are highly likely, but are typically not an annual event in Dummerston. With an average median residential value of ($ 208,500) in April 2008, and assuming one structural fire resulting in the total loss of a structure happens on average once every two years, structural fires could result in ($ 104,250 ) in damage in an average year. Winter / Ice Storms Damage from heavy snow and ice storms can vary depending upon wind speeds, snow or ice accumulation, storm duration, and structural conditions (such heavy snow and ice accumulation on large, flat roofed structures). The assessed value of all residential and commercial property is ($ 262,468,600 ) Assuming a range of town-wide damage of 1% to 5%, a heavy snow or ice storm could result in ($ 2,624,686 ) to ($13,123,430 ) of total damage. Annex B Page 9

10 Power Failure Potential loss estimates are difficult to predict for power failures, which typically are isolated in geographic area and short in duration. Therefore, they often have only minimal impact to people and property. Power failures usually result in minor inconveniences to residents; however, longer duration events might result in the loss of perishable items and business losses. Power outages in winter months could result in the loss of home heating, bursting water pipes and resulting structural water damage.

The first is a Spill Prevention Plan that identifies components of the Treatment Facility and collection system that may be prone to failure, which if would cause a significant release of untreated or partially treated sewage into waterways. The Town also has an Emergency Action Electric Power Failure Plan to deal with potential long term power outages. This plan includes the Treatment Plan and each pumping station calculating the amount of storage each location has and how long of a period they can go without power before pumping is needed. There is back up power at the treatment plant and a portable generator that can be taken to each pumping station to provide enough power to pump down to a normal level. Identified Hazard Mitigation Programs, Projects, and Activities The Dummerston Hazard Mitigation Committee identified the following new hazard mitigation activities based on an evaluation of hazard event vulnerability not addressed by existing hazard mitigation initiatives and the feasibility of new activities. Mitigation strategies for existing buildings and infrastructure: The Town of Dummerston has a lengthy comprehensive list of mitigation projects for the next 25 years. These are areas in the town where they know either road stabilization, culvert replacement, bridge work or road repair needs to be addressed and fixed. They are listed by the town in the order of priority based on the basic principles of safety and general welfare for the town. 1) Quarry Road 6 x 35 Arch culvert replacement. This project has had an hydraulic study completed in August 2009 by Hydraulic Engineers recommending replacement of current arch. The estimated cost is $175,000, estimated to be replaced by Annex B Page 12

13 2) Stickney Brook Road Replacement of 6 x 6 arch by the year 2015, cost $80,000. 3) Dutton Farm Rd - There are no culverts in a large section of the road. The Town would like to put in culverts as well as a Basin in the drainage ditch to alleviate siltation in the brook. Estimated cost would be $175,000 by ) Parklaughton Road Replacement of 6 Arch. Estimated cost $65,000 by ) Stickney Brook Road #2 Replacement of 8 Arch. Estimated cost $75,000 by ) Covered Bridge on Rt. 30 Retaining Walls The bridge needs retaining walls as soon as funding allows. 7) NIMS/ICS training for Town Officials such as Selectboard. Dummerston does not have a Town Manager, but does have an EMD. Mitigation strategies for new buildings and infrastructure: Not applicable at this time. Implementation Schedule for Prioritized Mitigation Projects 1 The following implementation schedule was developed by the Town Road Foreman and is directly taken from the current Bridge and Structure Inventory for the Town of Dummerston. Mitigation actions are listed in priority order, with the most critical needs listed at the top of the list. The Road Foreman used criteria such as the age of the structure, structural safety and adequacy and serviceability to determine the condition of structures. The most critical need is listed as number 1 with the least critical need ranking at 6. The ranking of these criteria is largely based on the best available information and best judgment as many projects are not fully scoped out at this time. The actions are listed in the table below in order of how they scored based upon the ranking given by the Road Foreman. The following list of mitigation strategies was put together in DATE by the Planning Commission of Dummerston, VT. At the time of applying for FEMA s PDM-C, FMA or HMGP grant programs, each project listed below will undergo full benefit-cost analysis (BCA) methodology, version 4.5 or higher to maximize savings.
