We also sincerely thank Christina Queen, who provided insight into how repetitive loss and severe repetitive loss properties are tracked within NFIP data systems. We are grateful to the FEMA regional staff and community-level officials whom we interviewed to gain essential context for understanding the complexities of addressing multiple loss properties. The report was improved through the insightful comments of our peer reviewers-Paul Osman (Oz Consulting and former floodplain manager at the Illinois Department of Natural Resources), Chad Berginnis (Executive Director of the Association of State Floodplain Managers), Jason Barnosky (senior political scientist, RAND Corporation), and Susan Resetar (senior operations researcher, RAND Corporation). Finally, we thank Maria Vega for her thorough edit of the document.
