The Plan was developed by the Wolfeboro Hazard Mitigation Planning Update Committee (the Committee) with assistance from the Lakes Region Planning Commission, and contains statements of policy adopted by the Board of Selectmen in Chapter VI. The Committee determined high and moderate natural and human-related risks, based on a ranking system detailed in Chapter III, and shown below: High Risk Moderate Risk Flood Earthquake Severe Winter Weather Tornado Power Outage Chemical Spill/Water Contamination Hurricane Drought/Water Shortage Severe Thunderstorm/Lightning Mass Casualty Pandemic/Epidemic HazMat (Transportation) Transportation Incident Intentional Water Contamination Population Surge Dam Failure Major Woodland Fire HazMat (Fixed location) The Committee identified numerous existing programs related to hazard mitigation including the following: Existing Plans, Regulations and Practices Supporting Hazard Mitigation Hazard Mitigation Plan 2007 Lakes Region Household Hazardous Product Facility Code Enforcement Public Health Emergency Preparedness Plan
