My work explores the application of GIS in flood risk communication. Specifically examining the layering of quantitative and qualitative data from various sources I implemented a proof-of-concept project in Boulder County, Colorado. First, I analyzed the success of various interpolation methods in creating a continuous raster layer of the 100-year flood, where pixel values denote water surface elevation, from NFHL cross-sections. The best output was then used injunction with building footprint data to provide residences with structure-specific information. Secondly, utilizing focus groups, I researched local knowledge and communication and data preference for bottom-up data contributions. Lastly, combining these parts, I created a web app title 'Flood Risk Information System', which aims to serve as a replicable communication tool between stakeholders and fill existing gaps in flood risk perception.
