Franklin County Hazard Mitigation Plan Update Risk Assessment

Franklin County Hazard Mitigation Plan Update Risk Assessment 1

What are we going to talk about? ü What is Mitigation ü The Disaster Mitigation Act of 2000 ü Franklin County’s response to DMA ü Why Update ü The Plan Update Process ü The Risk Assessment

What is Mitigation? Preparedness Mitigation Response Recovery “Sustained action taken to reduce or eliminate long-term risk to life and property” (Prevention)

What is the Disaster Mitigation Act (DMA)? Federal legislation that establishes a predisaster hazard mitigation program and new requirements for the national post-disaster Hazard Mitigation Grant Program (HMGP) NO PLAN, NO MONEY!!

What is Required in a DMA Plan? According to Section 201. 6, 44 CFR, an approved plan must: n Engage the public through all phases of the plan’s development n Review and incorporate plans and programs that can support/enhance hazard mitigation n Assess risk to natural hazards that impact a planning area n Identify a plan maintenance strategy n Identify and prioritize actions

A Multi-Jurisdictional Plan n Preferred format by FEMA n Identifies/creates the partnerships that enhance grant funding opportunities n For multi-jurisdictional plans, all participating jurisdictions must: • Participate in the process • Rank Risk • Perform a capability assessment • Identify/Prioritize jurisdiction specific actions

Benefits of Hazard Mitigation Plans n Establish / maintain eligibility for grant funds n Preparedness: pro-active vs. reactive n Sustainability n Key element in emergency management n Can set the course for response and recovery to impacts from natural disasters n Requires commitment and support from both the political faction and your constituency

Response to the DMA in Franklin County adopted its first hazard mitigation plan in 2009. n Following the expiration of that plan, Franklin County received funding to update the plan in 2015. n The current Franklin County Hazard Mitigation Plan was approved by FEMA and adopted by participating jurisdictions in 2017. n The current plan expires November 19, 2022.

Why Update? Because it is required. Section 201. 6 44 CFR states that approved HMP’s must be updated at least every 5 years to remain eligible under the DMA. Because plans are no good if they sit on a shelf. Effective plans are dynamic which means they are reviewed and enhanced regularly.

The Plan Update Process n n n n Task 1: Determine Planning Area and Resources Task 2: Build Planning Team and Create Outreach Strategy Task 3: Review Community Capabilities Task 4: Conduct Risk Assessment Task 5: Develop Mitigation Strategy Task 6: Review, Revise, and Submit Plan Task 7: Adopt Plan

Risk Reduction To reduce Risk: F Manipulate the Hazard: • F Reduce Exposure: • F property acquisition Reduce Vulnerability: • F structural flood control retrofitting Increase capability: • $, preparation, technical assistance, planning

Steps of the Franklin County Risk Assessment 1. Describe Hazards (location, extent, previous occurrences, probability of future events) 2. Identify Community Assets (people, economy, built and environment) 3. Analyze Risk 4. Summarize Vulnerability
