Establish a plan to prioritize and acquire undeveloped properties within flood zones throughout Town. Flooding zones Effective Undeveloped properties need to be re-identified. Prepare a priority list and seek funding through the Hazard Mitigation Grant Program (HMGP) for the replacement of undersized culverts throughout town, both those currently identified and culverts that have identified. Flooding Entire Town Effective Identify all undersized culverts. Drainage repairs on roads that consistently ice over to lessen the potential for future damage to Monson’s residents. Severe Snow/Ice Storms Select Roads Effective Prioritize repairs. Reverse 911 for mass notification in the event of a large catastrophic complication from a Hurricane, such as a dam breach. Hurricanes Entire Town Effective Incorporate with previous Reverse 911 strategy. Clear high-risk trees away from critical infrastructure and facilities to ensure that these will be most fully operational in all events, especially wind related events. Tornadoes Select Areas Effective None. Complete. Tornado education pamphlet to help residents identify tornado conditions as they might appear in Monson. Tornadoes Entire Town Not effective; no action ever taken. Create education pamphlet that is not specific to tornadoes. Continue to develop and distribute an educational pamphlet on fire safety and prevention. Wildfires/Brushfires Entire Town Effective. Wildfire hazard information is on town website. None. Wood in forests knocked down by tornado is decaying and less of a threat. Install sufficient back-up generator in all shelters and critical facilities to ensure operations in the event of a primary power failure. Earthquakes Entire Town Effective None. Back-up generator is effective. Map inundation zones to determine how heavily impacted critical facilities in the center of town would be in the event of a major dam breach. Dam Failure Select Areas Effective None. Complete.
Construct flood walls at critical facilities to lessen the impact of a major Dam Breach. Dam Failure Select Areas Not effective. None. Not cost effective. Establish action plan that addresses hazardous chemical spills and releases at EPA Tier II locations and on transportation routes. Man-Made Disasters Entire Town Effective. Action plan is part of CEMP. None. Complete. Deleted or Completed Mitigation Strategies Several mitigation strategies listed in the 2007 version of the Monson Hazard Mitigation Plan have been removed in this 5-year update. Strategies were deleted for one of two reasons: 1) They are determined as no longer effective to mitigate a hazard, 2) They are in need of replacement by a more specific mitigation strategy. Action Hazards Mitigated Responsible Agency Reason for Deletion Examine current notification system including feasibility of Reverse 911. Develop a preliminary project proposal and cost estimate. All EMD Reverse 911 has been adopted and is a capability. This strategy needs to be further defined to make the tool more Update Monson’s Natural Hazard Mitigation Plan every Five (5) Years. All EMD Strategy is too general and Monson updates its plan as a matter of course (existing capability).
