  • Watershed boundaries shows the larger drainage basin. For more information see King County watersheds. 
  • Council districts show the areas for the nine elected King County Council Members.
  • Streams shows the location and names of streams. You must zoom in to see this feature.

To zoom in or out, click on the + or - icon on the upper left corner of the map. You can also re-position by clicking and dragging, or re-center by clicking the home button.
