In 2013 our hometown of Boulder, Colorado was hit with one of the worst floods in the last hundred years. Widespread devastation led to lives being lost and entire roads disappearing altogether. Though much of the city has since been rebuilt, signs left from the flood’s terror remain as do the memories of its destructive path. Fortunately, Boulder has worked hard through new infrastructure initiatives and research to prepare the city for its next encounter with Mother Nature. In this map, the widest extent of the 2013 flood is overlaid on layers of Boulder’s building footprints and regular creek paths, providing a much clearer picture of the widespread flooding. Compare this visual representation with a mere table of statistics to see the storytelling power of maps. Moreover, this map acts as an example of Map Mavin’s excellent applicability to emergency response. With features like Screen Share that lets users join the same map and edit it simultaneously while also using a built-in chat option, members of a response team can stay quite literally “on the same page”.
