Regenerative parks and parkways

  1. 1. Regenerative Parks and Parkways: Local Harvests and Enhancements in Our Community Commons by Brad Lancaster www.HarvestingRainwater.com www.DesertHarvesters.org
  2. 2. What is the story of your place? What is your role in that story? What is the role of your public land (parks, parkways, rights-of-way) in that story? 2
  3. 3. Sponge Drain 1904 Tucson, Arizona, U.S.A and the Santa Cruz river 2007
  4. 4. Floods that occurred every 100 years begin to occur every 10 years - after development paves the watershed and increases the rate and volume of stormwater running off site
  5. 5. Distance is energy We ignore, deplete, or pollute our local waters — then import ever more distant water The largest consumer of electricity (and single source producer of carbon) in Arizona is the pumping of water
  6. 6. The average annual rainfall in Tucson is (280 mm) 11 inches Yet more rain falls on the surface area of Tucson in a year of average rainfall, than the annual consumption of Tucson’s water-utility water Said another way, in you were to divide the average annual precipitation falling on Tucson by its population, then divide again by 365 days a year, and you get:
  7. 7. Harvest and utilize on-site water (rainwater, stormwater, greywater, c ondensate, etc) as close as possible to where it falls within the oasis zone - within 30’ (9 m) of catchment surface
  8. 8. Path to Scarcity Path to Abundance • Turns resources into wastes • Relies on the costly and imported • Consumes more than it produces • Disintegrated Drains • Turns ―wastes‖ into resources • Relies on the free and local • Produces more than it consumes • Integrated Harvests
  9. 9. Cutting street curb
  10. 10. In Tucson, AZ (receiving 11 inches [280 mm] of annual rainfall) One mile of an average residential street drains over ONE MILLION GALLONS of rainfall per year. That’s enough water to sustainably irrigate 400 native food trees per mile, or one tree every 25 feet on both sides of the street - irrigated by the street.

  13. 13. Curb cuts legalized in 2007 $45 permit
  14. 14. Curb core hole 4-inch (100-mm) diameter
  15. 15. Prunings from tree used as mulch to fertilize tree and increase soil moisture 12 to 14% of the city’s solid ―waste‖ stream is yard trimmings Brush and Bulky transformed into Chipped and Mulchy
  16. 16. Chipped and Mulchy
  17. 17. Mitchell Pavao-Zuckerman, PhD Biosphere 2 & School of Natural Resources and Environment University of Arizona mzuckerman@arizona.edu • Trees associated with mulched water-harvesting earthworks are able to grow 33% larger than those without. This more than doubles the trees’ potential sequestration of atmospheric carbon, passive cooling, and food production • The presence of more organic matter in the soil enables the soil itself to sequester additional carbon • The natural pollutant- filtering/bioremediation ability of the soil mulched with organic material was ten times greater than that of rock- or gravel-mulched soil

  21. 21. The neighborhood now annually harvests over 660,000 gallons (2 acre feet) of stormwater in the public right-of-way within 10 water-harvesting traffic circles, 33 chicanes, and 85 street-side basins fed by 50 curb cuts and 35 cores But we could, and need to, increase that harvest by at least 30 times Before chicane ^ After chicane >

  24. 24. Scarcity – heat island Abundance – cool island 5.5 ˚C (10˚F) increase of summer temperatures 5.5 ˚C (10˚F) decrease of summer temperatures
  25. 25. Scarcity – heat island Abundance – cool island 5.5 ˚C (10˚F) increase of summer temperatures 5.5 ˚C (10˚F) decrease of summer temperatures

  27. 27. Public right-of-ways must not be limited to private utility rights-of-ways
  28. 28. Green Streets Portland, Oregon
  29. 29. City of Portland, Oregon Sustainable Stormwater Overlays courtesy of Dave Elkin City is divided up into subwatersheds, and those of highest need are identified. Combined Sewer Overflowsand flooding are the typical problem
  30. 30. Conventional drainage design cost $144 million
  31. 31. Plan with sustainable stormwater strategies cost $86 million. $58 million savings due to the reduction of needed pipe replacement

  35. 35. Death According to Grave Matters, today the U.S. funeral industry buries over 3 pounds of the formaldehyde-based ―formalin‖ with every embalmed body (totaling 800,000 gallons [3,028,000 liters] of formaldehyde a year) Over time the typical ten-acre [4 ha] swath of cemetery ground contains enough coffin wood to construct more than forty houses, nine hundred-plus tons [816,000 kg] of casket steel, and another twenty thousand tons [18,143,000 kg] of vault concrete
  36. 36. To Life A green burial does not allow toxic embalming, concre te vaults, or elaborate caskets, which can reduce the cost of a burial by $8,000 to $12,000
  37. 37. Honey Creek Woodlands Georgia’s First Conservation Burial Ground It is part of an 8,000-acre conservation effort known as the Arabia Mountain Heritage Area along the South River www.GreenBurials.org
  38. 38. What could be the story of your place? What will be your role in that story? What will be the role of your public land (parks and parkways) in that story?
