Partner Identification Community Outreach Discovery Meeting Discovery Report in good standing as an NFIP participant RESILIENCE MEETING FEMA, State and local officials, and partners work to identify and review resilience strategies. planning options, and potential actions to reduce risk. 2 ENGINEERING & MODELING FEMA analyzes the information gathered during Discovery and develops the first draft of the maps, called "work maps." communities to adopt the new flood maps. EFFECTIVE MAPS 9 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.

The Discovery process of FEMA's Risk MAP program helps communities identify areas at risk for flooding and solutions for reducing that risk. Discovery Next Step Risk MAP Discovery Capturing a More Complete Picture of Your Watershed#15• • Discovery Holistic view of a geographic area; watersheds cross jurisdictional borders - Ownership of Risk Develop partnerships, combine resources, share flood risk information, develop a vision for the watershed - Whole Community Identifying and empowering communities to take action to reduce their flood risk Resiliency#16Why is Discovery Important?
