Proposed Duwamish Floating Wetland Design
THIRTEEN oC DESIGN REFLECTIONS Pros
Stensland Creek: -Inexpensive -Simple -Natural + available materials -Easy construction -Movable Duwamish: -Durable -Abundant biofilm surfaces -Adjustable heights for differing shoreline conditions -Reusable materials
Cons
Stensland Creek: -The timeline it would take for plant growth and to fully be a useful means for shading -Unsure of plant growing capabilities -Durability -Bird use Duwamish: -Expensive materials -Construction cost -Material availability -Unsure of plant growing capabilities -Hard to transport out of water -Maintenance -Bird use
Questions
Stensland Creek: -Will the willow and dogwood clippings sprout, and if so is the layer of emergent plants or the coir necessary? -Will the plants thrive? -How buoyant or stable is the bamboo structure? -Are the extra floating devices needed? Duwamish: -How well can a plant community establish itself in the synthetic planting matrix? -What about invasive species? -How can this design be more aesthetically pleasing? -How can ecological literacy be present in the design, since it will be highly visible by boaters?
