3. Our Mission Conduct a Flood Risk Index (FRI) Pilot Study Create Guidelines to Assist Communities Generate Recommendations for the City of Cape Town Worcester Polytechnic Institute

4. Information Collection • Settlement Visits • On-Site and City Interviews • Case Study Research • GIS and Rainfall Data Analysis • Brainstorming Worcester Polytechnic Institute

5. Incoming Residents are Unaware of High Risk Areas Addressing the Issues Associated with Flooding Poor Location Infrastructure Blockages Lack of Resources Increased Flood Risk within the Informal Settlements Worcester Polytechnic Institute

6. Flood Risk Index – Pilot Study Prototype Flood Risk Index Purpose: • To prioritize settlements at higher flood risk for housing upgrade • To determine appropriate community capacity measures to be implemented in a settlement • How it works: • Based on measurable indicators • Probability of a flooding event • Topography • House structure susceptibility • Community capacity and awareness

7. Flood Risk Index – Pilot StudyMapping High-Risk Areas • Purpose: • Indicate areas with high flood risk based on topographical location • Use findings for topographical indicator in the FRI

8. Flood Risk Index – Pilot Study Flood Incident Reporting Worcester Polytechnic Institute

9. Improved topographical data collection methods More precise records of displaced residents Flood marshals Flood Risk Index – Pilot StudyRecommendations Worcester Polytechnic Institute

10. Flood Risk Index – Pilot StudyFlood Marshals • Sets foundation for FRM at community level • Consistent data collection • Community education Worcester Polytechnic Institute
