Sherburne County Multi -Hazard Mitigation Plan, 2020 4.2 Future Development Because Sherburne County is vulnerable to a variety of natural hazards, the county government —in partnership with the state government —must make a commitment to prepare for the management of these events. Sherburne County is committed to ensuring that county elected and appointed officials become informed leaders regarding community hazards so that they are better prepared to set and direct policies for emergency management and county response. At the local jurisdictional level, several communities did note an increase in development overthe last five years as a factor for an increase in vulnerability to severe weather or disaster events (see Section 4.1.2, Vulnerability Assessment by Jurisdiction). In the development of local mitigation actions, all jurisdictions were encouraged to consider hazard mitigation strategies that would reduce risk in relation to future development, such as the update of local comprehensive plans, enforcement of ordinances and incorporation of infrastructure improvements to reduce local vulnerabilities. (See Appendix G Mitigation Actions by Jurisdiction). The Sherburne County Emergency Management Director will work to keep the jurisdictions covered by the Multi -Hazard Mitigation Plan engaged and informed during the plan's cycle. By keeping jurisdictional leaders involved in the monitoring, evaluation and update of the MHMP, they will keep their local governments aware of the hazards that face their communities and howto mitigate those hazards through planning and project implementation. Section 6 of this plan further outlines the process by which Sherburne County will address the maintenance of this plan, including monitoring, evaluation, and update of the plan, as well as implementation and continued public involvement. 4.3 Hazard Profiles As part of the risk assessment, each natural hazard that poses risk to the county was independently reviewed for its past hazard history, relationship to future trends, and jurisdictional vulnerability to future events. A capabilities assessment was also conducted by the county to review the plans and programs that are in place or that are lacking (program gaps or deficiencies) for the implementation of mitigation efforts, as related to each natural hazard. An assessment was also conducted for local jurisdictions to identify the plans, policies, programs, staff and funding they have in place in order to incorporate mitigation into other planning mechanisms (see Section 5.3. Community Capability Assessments and Appendix K. Local Mitigation Survey Report). Summer Storms, all given a risk severity of "high" by the planning team, are profiled separately as Tornadoes, Windstorms, Lighting and Hail in sections 4.3.3.through 4.3-4. 4.3.1 Tornadoes Tornadoes are defined as violently -rotating columns of air extending from thunderstorms to the ground, with wind speeds between 40-300 mph. They develop under three scenarios: (i) along a squall line; (2) in connection with thunderstorm squall lines during hot, humid weather; and (3) in the outer Page141
