Display Materials:

Additional Resources:
  • WaterMaps – This online GIS mapping tool was created by King County and is what IslandWood used to create most of the school-specific pipe maps.  If is designed for teacher and student use, but we are still refining some of the usability features.  If you have access to a couple students that would benefit from a more open ended challenge, you could provide it to them to explore. Here are directions for using WaterMaps.
  • Seattle Public Utilities Citywide Stormwater Map 
  • Combined Sewer Overflows Status (live) – Teaching about stormwater during a big rainstorm?  This King County website shows you which CSOs in Seattle are currently overflowing or have overflowed in the last 48 hours!
