Flood Protection Standards

We worked with Natural Resources Defense Council to create an animated web map and charting application that allows visitors to explore how $48.6 billion in FEMA Public Assistance Grants were spent in the wake of floods each year from 1998 to 2014.  This tool will be used by both the public and by policy makers to inform decisions about national Flood Protection Standards.
​
This project gave us the opportunity to play with animating semi-transparent polygon maps, including some unique methods for blending colors as the map layers were added and removed throughout the animation.  CartoDB's SQL API gave us a quick and easy way to store and pull the data for each year in the animation.  We used chart.js to display an animated bar chart of annual grant expenditures, and lots of jQuery to provide easy data interactivity, including the ability to select and receive additive statistics for multiple polygons and switch between county and state boundary maps.
