OSCEOLA COUNTY HAZARD MITIGATION PLAN INFORMATION HAZARD MITIGATION PLAN: The Osceola County Hazard Mitigation Plan was adopted in 2015 and will expire in 2020. The plan organized the hazards into 11 major hazard considerations: Mass Casualty Incidents, Infrastructure Failure, Inclement Weather, Tornadoes, Severe Winter Weather. FLOODING: Flooding and flood related hazards were ranked as a high priority for most of the jurisdictions in the Osceola County. The county has had 11 significant flood events occur on 10 different dates between 1996 and late 2013. Most of the flooding is related to heavy rainfall events. Osceola County has five properties that have been identified by the National Flood Insurance Program as having suffered repetitive losses from flood damages. This plan recommends the prioritization of flood mitigation activities for these repetitive-loss properties, as feasible. DAM FAILURE: Osceola County classifies Dam Failure in the same major hazard consideration as flooding. Dam failure is a collapse or failure of an impoundment that causes downstream flooding. Osceola County does have dams but none of them have been prioritized in this plan.

OSCEOLA COUNTY | MICHIGAN RISK MAP: DISCOVERY WHAT IS RISK MAP?
THE MUSKEGON RIVER WATERSHED
The FEMA Risk Mapping, Assessment, and Planning (Risk MAP) program provides communities with hazard information and tools they can incorporate into existing planning efforts to reduce risk. The Risk MAP program is composed of a series of meetings, data collection, and assessment phases.
The Muskegon Watershed is located in northcentral Michigan, and has a drainage area of approximately 2,738 square miles, making it one of the largest in the state. There are 12 counties and 133 communities that are within the Muskegon Watershed. Of these counties, large portions of Roscommon, Missaukee, Clare, Osceola, Mecosta, Newaygo, and Muskegon Counties are drained, as well as are smaller portions of Kalkaska, Crawford, Wexford, Lake, and Montcalm Counties.
WHAT IS DISCOVERY? This first phase of Risk MAP is Discovery, which has the following three areas of focus: • Working closely with each community to identify areas at risk from natural hazards • Gathering local data • Reviewing mitigation plans to understand local mitigation capabilities and exploring potential solutions for reducing risk
WHY PARTICIPATE? By participating in Discovery you will:
THE DISCOVERY MEETING FEMA hosts an in-person Discovery Meeting to discuss and explore the opportunities for a Risk MAP project. The goal of the meeting is to: • Continue the discussion of natural hazard risks and ways to mitigate those risks • Discuss and connect to various risk assessment tools available from FEMA to support and enhance resilience efforts
• Build relationships and collaborate with local, State, and Federal agencies
• Prioritize areas of potential studies and projects that will be considered for scoping a Risk MAP project
• Gain access to quality data, maps, updated flood studies, risk assessments, and outreach strategies
WHO SHOULD PARTICIPATE?
• Become connected to training opportunities and community outreach resources
Federal, State, regional, academic, non-profit, and other community-based organizations interested in hazards and/or land use.
AFTER THE DISCOVERY MEETING FEMA uses the information gathered to prioritize scoping efforts to fund future mapping, risk assessments, and/or mitigation planning assistance through a Risk MAP project.

FLOOD RISK REVIEW Community officials review and provide initial feedback on the work maps and engineering decisions. FEMA uses the feedback to modify the maps and develop the preliminary Flood Insurance Rate Map (FIRM). Using this information, officials begin to identify and advance mitigation action in their community.

PRELIMINARY MAP RELEASE • Community Coordination and Outreach Meeting Community officials learn the implications of the updated map and the steps and timeline to adopt the updated map. • Open House Citizens learn about their local flood risks, and what resources are available from the State, FEMA, and other partners to reduce risk.
90-DAY APPEAL AND COMMENT PERIOD Following two public notices, community members can submit technical data to support a request to revise the FIRM though the 90-day appeals process. All appeals, including all supporting documentation, must be submitted through the appropriate community official.
6
ADOPTION & COMPLIANCE
7
Communities participating in the NFIP must adopt a compliant floodplain management ordinance by the map effective date to remain in good standing as an NFIP participant.
8
RESILIENCE MEETING (OPTIONAL)
After all appeals are resolved, FEMA sends a Letter of Final Determination, kicking off a six-month period for communities to adopt the new flood maps.
9
FEMA, State and local officials, and partners work to identify and review resilience strategies, planning options, and potential actions to reduce risk.
LETTER OF FINAL DETERMINATION
EFFECTIVE MAPS Once effective, new maps and products are available through FEMA’s Flood Map Service Center. The new data will inform flood insurance decisions and local building regulations. Community members can submit data to amend or revise the FIRM as part of a Letter of Map Change (LOMC) process.
