  1. Sustainable Stormwater Sustainability for all the places between the buildings

  2. Today’s Agenda Best Management Practices (BMPs) to protect water quality • With Infiltration • Without infiltration

  3. N Best Management Practices (aka BMPs)Two Types

  4. The Water Balance ModelWater Quantity Before X” rainfallyearly avg 40% evaporation 35% groundwater (deep infiltration) 0.005% runoff 23% base flow(shallow infiltration)

  15. Impervious SurfacesA Watershed Perspective

  16. If you win the infiltration argument…

  17. Structural BMPsUnderground infiltration facilities anywhere

  18. Vegetated Filter Strips

  19. Structural BMPsPorous Pavement on Lot 2 • Look ma! No runoff!

  20. Structural BMPs - Rain Gardens on less occupied areas of Lot 2 & Lot 3

  21. Structural BMPsDownspout Disconnections to some areas of Lot 2

  22. Dispersion

  23. While you’re making the case for infiltration, you might advocate for…

  24. Non-structural BMPsReduce lawns

  25. Swales instead of pipes

  26. Non-structural BMPsPollutant Source Control

  27. Non-structural BMPsCultural Landscape Practices Use compost not nitrogen fertilizers Lawn senescence

  29. Protecting Soil Protects Watersheds Image from Soil Quality Information Sheet, U.S. Department of Agriculture

  30. Non-structural BMPsKeep Soil Covered Courtesy of James Santana

  31. Non-structural BMPsLimit Compaction

  32. RELATIONSHIP OF FISH ACTIVITY TO TURBIDITY DEATH TURBIDITY (LOG 10) REDUCED GROWTH RATES * DELAYED HATCHING * LONG TERM REDUCTION IN FEEDING COVER ABANDONED * AVOIDANCE * INCREASED RESPIRATION * REDUCED FEEDING * INCREASED COUGHING RATES STRESS TIME (LOG 10) Non-structural BMPsPrevent Erosion Courtesy of James Santana

  33. Non-structural BMPsAmend Disturbed Soils with Compost

  34. Protecting Air Protects Stormwater

  35. Non-structural BMPsShade south facing walls

  36. Non-structural BMPsShade air conditioners

  37. Non-structural BMPsSalvage Materials

  38. Non-structural BMPsRecycle Construction Materials

  39. The Hydrologic CycleA Definition The continuous movement of water through everything.
