DALTON MULTI-HAZARD MITIGATION PLAN UPDATE 2018 Town of Dalton, Massachusetts December 2018 Acknowledgements The Dalton Multi-Hazard Mitigation Plan Update has been made possible with the financial support of a Pre-Disaster Mitigation Competitive Grant (PDMC 16-9), issued by the Federal Emergency Management Agency and administered by the Massachusetts Emergency Management Agency. The Town of Dalton would like to Dalton Emergency Management Advisory Council, who served as the Advisory Committee for the plan update, particularly Danial Filiault, Emergency Management Director and Chairman of the Council, who oversaw the planning process and completion of the plan update. The Berkshire Regional Planning Commission provided technical assistance to the Advisory Council throughout the planning process. Table of Contents Section 1.

INTRODUCTION AND BACKGROUND 1.1. Purpose of the Dalton Multi-Hazard Mitigation Plan According to FEMA a hazard is defined as “an event or physical condition that has the potential to cause fatalities, injuries, property damage, infrastructure damage, agricultural loss, damage to the environment, interruption of business, or the types of harm or loss.” Hazard mitigation is defined as a “sustained action taken to reduce or eliminate the long-term risk to people and property from hazards and their effects.” The Federal Disaster Mitigation Act of 2000 mandated that all localities prepare local hazard mitigation plans to be eligible for future FEMA funding from the newly established Pre-disaster Mitigation (PDM) grant program and for the existing post-disaster Hazard Mitigation Grant Program (HMGP), the latter of which is a mainstay of the FEMA grant programs. This Multi-Hazard Plan is an update of the Berkshire County Hazard Mitigation Plan, dated November 5, 2012, a regional plan in which the Town of Dalton was included with 18 other Berkshire County municipalities. Geographically this current plan update is a plan involving a single municipality, the Town of Dalton, Massachusetts. During the development of this plan other hazard mitigation plans in the region were consulted, including the neighboring communities of Cheshire, Lanesborough, Hinsdale and Pittsfield. The Plan is designed to serve as a tool to help town officials identify hazard risks, assess the town’s vulnerability to hazardous conditions, consider measures that can be taken to minimize hazardous conditions, and develop an action plan that can reasonably be implemented to mitigate the impacts of hazards in the region. This plan should be used in conjunction with other local and regional plans, specifically other hazard mitigation plans, the Town of Dalton Master Plan of 2016, Complete Streets Policy Plan, and a soon-to-be drafted open space and recreation plan. It is expected that this updated plan will be a foundation upon which to build a Municipal Vulnerability Preparedness Plan, which the Town expects to undertake in 2018-19. 1.2. Background The Town of Dalton is located in central Berkshire County, Massachusetts. Settled in 1755, Dalton is bordered by the City of Pittsfield and Town of Lanesborough to the west, the Town of Cheshire to the northwest, Towns of Windsor and Hinsdale to the east, and Washington to the south. The Town is located along the East Branch of the Housatonic River, which bisects the Town at its center. The Town is characterized by a forested, mountainous landscape historically suited to the development of water- powered mill industries, along the swift-moving Housatonic river and its tributaries. The well drained, glacial soils provide rich farmland to the Town’s interior, and the many tributaries, flood plains, reservoirs and wetland areas provide the Town with natural beauty, recreational opportunities and access to ample water resources. These same positive attributes also provide increased risk for flooding hazards, property damage and increased vulnerability in the more heavily populated areas, if not properly assessed, monitored and mitigated. As noted in the Town’s Master Plan and according to the U.S. Census Bureau’s American Communities Survey, in 2013 Dalton had a year-round population of approximately 6,744 persons, making it the 6th 1 largest community in the County. Census data indicates that the town population decreased from 7,155 to 6,756 residents between 1990 and 2010. This amounts to a 5.6% decrease in population over the 20- year period. Additionally, Dalton’s population is projected to decrease in the future. The Donahue Institute at UMass Amherst projects that Dalton will shrink by roughly 300 residents over the next two decades, approaching 6,379 year-round residents by 2035. The median age of Dalton residents is 46.9 years old. Between 2000 and 2013, the number of residents below the age of 45 decreased, while the number over the age of 45 increased. The town is expected to lose population over the next two decades, by about 365 residents. The aging and decline of the population follows a region-wide trend, that is expected to continue for the next four decades. According to 1999 land use, Dalton is Figure 1.1. Topographical Map of Dalton largely forested (76% land use coverage), with a mix of urban and suburban residential uses accounting for 9.3% of the developed acreage. The balance of acreage is devoted to a mix of institutional, commercial or industrial uses. Historically, development within the town has been concentrated around Main Street and the areas around the mills. These neighborhoods typically contain homes of older building stock. Dense residential neighborhoods radiated out around the town center. In the 1950s/60s modest, suburban developments occurred outside the town center, and in subsequent decades scattered single family homes and neighborhoods of larger lot, less dense residential development has occurred. Land use in Dalton is regulated through the town’s zoning bylaws, that includes four residential districts, two business districts and three industrial districts, as well as several overlays governing open space, flood plains and scenic viewsheds. 2 According to the Town’s Master Plan, Dalton has approximately 50 miles of roads, of which 2.5 miles are unpaved roads. Of the paved roads, MassDOT maintains approximately 6.6 miles, involving the major transportation corridors that are known as Routes 8 & 9. 3 SECTION 2. PLANNING PROCESS 2.1. Planning Committee The Dalton Emergency Management Department took the lead in developing the Dalton Multi-Hazard Mitigation Plan Update, creating an advisory committee that consisted of municipal department heads, representatives from various town boards and committees, and representatives from the Central Berkshire Regional School District, the Dalton Fire and Water District, and local businesses. Members of the Dalton Emergency Management Advisory Council are listed below, Table 1. Technical Assistance for the development of this plan were provided by the Berkshire Regional Planning Commission (BRPC). Table 2.1.

During the convening months the Advisory Council met four times to discuss data provided by BRPC, to gather more detailed and site-specific information, to discuss opportunities for improved preparedness and mitigation, and to begin to identify potential action strategies. All Council meetings were open to the public and complied with the Massachusetts Open Meeting Law. Town officials and the public were kept informed of the planning process through a variety of media, including posting of all meetings and meeting minutes on the Town’s website, and periodic updates were posted on the Emergency Management Department’s facebook page. The Emergency Management Director made periodic update reports to the Dalton Select Board, the meetings of which are televised on the local community television station. Additionally the EMD spoke to senior residents about emergency preparedness and the hazard mitigation planning process twice, one of which was televised. To garner further public input, the Advisory Council held a public forum to unveil the formal public review process for the draft plan. The forum, held on June 12, 2018, provided the public with an overview of the types of natural
