Design ecology a 21st century strategy

  1. 1. DESIGNECOLOGYA 21st Century Strategy
  2. 2. Existing Infrastructure• Straight Lines to Low Point Results in Flooding & Low Summer Stream Flows• Impacts to Habitat – poor water quality – loss of cover & biodiversity – low, warm stream flows, no O2• Impacts to Infrastructure – increased flooding with urbanization – combined sewer overflows – exceeded treatment capacity
  3. 3. Impervious Surfaces
  4. 4. Infrastructure Failures LOST BIODIVERSITY LOW STREAM FLOWS INCREASED HEAT MORE FLOODING THE RESULTS HAVE NOT BEEN GOOD ENERGY IMPACTS WATER QUALITY UNSAFE UNSANITARY
  5. 5. Integrated Systems
  6. 6. Bioswales
  7. 7. Flow-ThroughPlanters
  8. 8. Living Roofs residential
  9. 9. Living Roofs of Marin, Nueva School education: College

  12. 12. Living Walls• Water filtration• Storm-water conveyance• Storm-water detention• Reduction of cooling demand• Habitat for birds and butterflies• Air quality• Aesthetic benefit• Mitigate “Urban Heat Island”

  19. 19. Rainwater Harvesting Functional civic art in Seattle
  20. 20. ROOF CATCHMENT CALCULATIONS(CA) x (R) x (E) x (7.48 gal/cu. ft.) = GALLONSCA = CATCHMENT AREA (SQ. FT.)R = RAINFALL (FEET)E = EFFICIENCY 0.9 = STD ROOF 0.8 = GRAVEL ROOF 0.3 = GREEN ROOF EASY METHOD (standard roof only): each 1,000 SF of catchment area 1” of rainfall = 600 gallons
  21. 21. Infiltration Swales
  22. 22. Natural Swimming Pools • Natural Swimming Environment uses gravel, plants and light to keep pool clean • Chlorine-Free Water is healthy, clean and safe • Provides Wetland Habitat • Beautiful Landscape Element
  23. 23. NaturalSwimmingPools
  24. 24. Stormwater Mgt • Protect water quality • Reduce impacts to infrastructure • Reduce irrigation demand • Infiltration / recharge • Biofiltration
  25. 25. Stormwater MgtSEA Streets Seattle95% Runoff infiltrated to groundwater from 1.1 acre sub-basin
