Understanding RiskMAP: Enhancing Flood Hazard Mapping and Community Engagement

RiskMAP (Risk Mapping, Assessment, and Planning) is a nationwide initiative led by FEMA to strengthen flood hazard mapping and community resilience. It involves collaboration with local communities to address gaps in flood data, enhance public awareness, and support hazard mitigation plans. Key phases include watershed selection, data collection, and public engagement, culminating in detailed flood maps. Utilizing tools like Hazus for damage estimation, RiskMAP aims to improve data management and distribution, ensuring communities are better prepared for flood risks through informed decision-making.

  1. SARA RiskMAP Efforts FY 2012/2013

  2. What is RiskMAP? • Risk Mapping, Assessment and Planning • Nationwide program – builds on MapMod products • Collaboration between FEMA and local communities

  3. RiskMAPGoals • Address gaps in flood hazard data • DFIRM, LOMRs, GIS, terrain, etc. • Public awareness/outreach • measurable • Hazard Mitigation Planning • Risk-based • Enhanced Digital Platform • Improvement management and distribution of data • Alignment and Synergies • Risk analysis programs, community synergies

  4. FEMA Regions http://www.ncep.noaa.gov/newsletter/current/printable.shtml http://riskmap6.com/Home.aspx

  5. Phases • Watershed Selection – San Antonio River Watershed HUC8 • Discovery – data collection (starting Oct. 2012) • Project selection and meetings • Preliminary map issuance • CCO meeting • Public comment period • Revised preliminary maps issued • LFD, Effective Map issuance • Map maintenance

  6. San Antonio HUC8 Watershed

  7. SARA RiskMAP Tracks • Hazus • H&H • Non-regulatory products

  8. What is Hazus-MH? • FEMA’s methodology for estimating potential losses from disasters • Earthquake, Wind, Flood • Software application • GIS-based • Physical, economic, social impacts

  9. Impacts • Physical • Buildings, schools, critical facilities, infrastructure • Economic • Lost jobs, business interruptions, repair and re-construction costs • Social • Shelter requirements, displaced households, population exposure to hazards

  10. Damage Centers • Identified in Watershed Master Plans • Upper San Antonio River • Salado Creek • Annualized damage estimates • 10-yr, 50-yr, 100-yr, 500-yr flood events • Only consider structural damages • Flood reduction ratios for CIPs • Similar to a benefit/cost ratio • (damage reduction/CIP cost)

  11. Damage Centers

  12. Hazus – Bexar County Projects

  13. Hazus – Bexar County Projects

  14. Hazus – Bexar County Projects

  15. Bexar County DFIRM • Effective Sept. 2010 • Detailed Studies – Zone AE’s • Digital Conversions/Redelineations • Zone AE’s • Zone A’s • Limited Detailed Studies – Zone A’s • Approximate Studies – Zone A’s

  16. Potential H&H Deliverables Refined/updated: • Models • Maps (LOMCs) • Data
