The Cedar River Watershed is the primary source of water for 70 percent of the 1.3 million people living in the greater Seattle area...Each year over 30,000 visitors come to the Cedar River Watershed Education Center to learn about the human and natural infrastructure for water.
In the design of the Education Center, as many features as possible were incorporated towards educating visitors about the ecology of the watershed. The result was a long list of various sustainable techniques and strategies, and care was taken to ensure the visibility of these features.
Among the ecological design features are:
1. A "living" roof system (eco-roof) whose soil and plants retain rainwater and naturally filter it.
2. A constructed stream which collects the surface drainage and roof water. Drainage is channeled into bioswales which filter and purify the water before it reaches the Rattlesnake Lake resvoir.
3. Organic mulches, Waterless urinals, rain barrels to catch water for reuse as irrigation
4. Green building materials such as formaldehyde-free medium-density fiberboard
