Introducing the Stormwater Heatmap 

What if we could see where pollution was generated across the entire landscape? What if we could identify hotspots of pollution in our region before it entered natural waterways? How might we change our approach to stormwater and pollution management so that people and nature can thrive? By making the invisible visible the Puget Sound Stormwater Heatmap is designed to help communities take targeted, high impact action on rolling back a legacy of pollution.
