October 2020 Webinar - General First Street Flood Model Methodology

The October 2020 Webinar gave an overview of the general First Street Flood Model methodology. A link to this webinar can be found here; if you are interested in accessing the presentation follow this link.  

This webinar provides an overview of First Street Foundation, who we are, why we exist, and the key differences between First Street Foundation Flood Model and FEMA. The webinar explains the data currently available (as of October 2020) including Flood Factor V1.0, significant findings from our national report, and AWS and data access.

  • Flood Factor V1.0: First Street walks through the incorporation of climate data for future prediction of flood risk. Combining flood risk (tidal, pluvial, fluvial, and surge) is also discussed as well as the incorporation of adaptation into the First Street model.
  • National Report: First Street discusses Risk Factor and its business model centering around transparent, open data. First Street gives an overview of its findings in its national report and gives a deeper look into Florida.
  • AWS and data access: Information on creating an AWS account and accessing First Street’s aggregate data.

The webinar concludes with a discussion about Flood Factor V1.1 and data changes, Data resource sharing, and finally ending in a Q&A.

  • Flood Factor V1.1: This version update covered more properties and refined the data further.
  • Data resource sharing: First Street discusses ways in which users can help improve their flood model.
