Green City... Clean Water

  1. 1. Green City… Clean Water Blending interests of land and water Howard M. Neukrug, PE Director, Office of Watersheds City of Philadelphia
  2. 2. Philadelphia Water Department Office of Watersheds • An integrated utility: • Drinking Water • Wastewater • Stormwater • A new integrated approach: • Land • Waterways • Infrastructure • Community
  3. 3. Philadelphia Water Department Office of Watersheds Combined Sewer Overflow Long Term Control Plan Update (CSO LTCPU) • $1.6 billion, 20 year program • Upgrade WPCP wet-weather capacity • Restore and protect all urban streams • “Green” 1/3rd of the city in 20 years • Reduce overflow volume by half
  4. 4. Philadelphia Water Department Office of Watersheds Weaknesses of the plan: • Overflows will continue • Costs will exceed affordable limits • Upstream – no changes • The plan relies on strong utility leadership, partnerships, fiscal responsibility, innovation and.. • a city that is striving to become a growing, sustainable city (we need a sustainable city to have a sustainable utility and the city needs this plan to become sustainable)
  5. 5. Why is Green Infrastructure Critical to Philadelphia? • Continuing the old approach is unsustainable • Environmental justice • Shrinking cities • Old infrastructure • Large percentage of low income households • New opportunities • The Greenest City in America • Time of large-scale community renewal • New focus of sustainability, urban waters, open space, Climate change
  6. 6. Vacant land becomes the Lower Mill Creek Garden
  7. 7. A new approach for SUSTAINBLE Cities!! MSU Green Roof Research Program (courtesy Old House Journal)
  8. 8. Innovations
  9. 9. Depaving Party in Portland, Oregon Brent Wojahn / The Oregonian “Breaking stuff is fun!”
  10. 10. Air Gardens Image: Todo Design and Das Studio
  11. 11. Green Roofs around the world Fukuoka City, Japan. A garden roof with 35,000 plants in low, landscaped terraces that step down into a park.
  12. 12. New Thinking About Philly Streetscapes
  13. 13. The History of Water Guns
  14. 14. Springside School
  15. 15. Greywater Guerillas
  16. 16. Urban Farmers: Vacant lots to Markets Photo by Hannah Y Juan/ Plantings by displaced people in Bogota’s main plaza Todd Heisler/The New York Times
  17. 17. Biomimicry Janice Konstantinidis Long as I remember the rain been comin’ down. Clouds of mystry pourin confusion on the ground. Good men through the ages, tryin to find the sun; And I wonder, still I wonder, who’ll stop the rain? -Creedence Clearwater Revival
  18. 18. si x a r P n n e P d n a T R W f o y s e t r u o C Sustainable Site Design
  19. 19. Planning for land can improve our water
  20. 20. Planning for our water can improve our land Civic Vision for the Central Delaware
  21. 21. The old approach to managing water
  22. 22. Crooked Streams are a menace to life and crops… In addition, much of the dirt is loosened and later scoured out by the water …which rushes swiftly through the straightened channel
  23. 23. There are significant issues ahead of us for improving the water environment PLUS: LTCPU, 308 letter, state COA, new permits
  24. 24. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer Photo: Black & Veatch
  25. 25. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer • Spend capital dollars above the ground, not below it
  26. 26. Chicago’s Millennium Park
  27. 27. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer • Spend capital dollars above the ground, not below it • Restore the urban waterways
  28. 28. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer • Spend capital dollars above the ground, not below it • Restore the urban waterways • Recognize that for PWD to be a sustainable utility, our city must be sustainable
  29. 29. Percentage of income •
  30. 30. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer • Spend capital dollars above the ground, not below it • Restore the urban waterways • Recognize that for PWD to be a sustainable utility, our city must be sustainable • Solve multiple problems at once
  31. 31. The Public is equally interested in all things water Streamflow and Living Resources, 12% Quality of Life, 12% Flooding, 11% Stream Corridors, 11% Stewardship, 11% Pollutant Loads, 10% Stream Habitat and Aquatic Life, 9% Water Quality, 9% Coordination, 8% Stream Channels and Banks, 7%
  32. 32. Example of How Benefits are Linked Tree planting Air quality Cooling Aesthetics Water quality Energy Reduced savings heat stress Health Energy cost Reduced GHG Enhanced benefits savings emissions property values
  33. 33. Triple Bottom Line Economic/Environmental/Social Benefits • Costs • Ecological Benefits • Recreation • Heat Stress Mortality • Energy Savings • Air Quality • Carbon Footprint • Aesthetics • Jobs • Property Value
  34. 34. TBL Benefits • Jobs - 250 people employed annually • Recreation - 10% more recreation and stream related visits • Property Values - $390M increase to homes near parks and green areas • Heat Related Fatalities - 140 fewer • Premature Deaths - 1-2 avoided / yr • Asthma Attacks - 20 avoided / yr • Missed Days of School / Work - 250 fewer / yr • Carbon Dioxide Emissions - 1.5 Billion lbs avoided/absorbed • Water Quality and Habitat Improvements - $8.5M • 45 acres of restored wetlands • 148 acres of wetlands created • 11.1 miles of streams restored
  35. 35. Total Benefits of Green City, Clean Waters over the next 40 years $2,500,000,000 Reduction in Construction- Related Disruptions (0.2%) Carbon Footprint Reduction $2,000,000,000 (0.6%) Energy Savings (1.0%) $1,500,000,000 Avoided Social Costs from Green Jobs (3.7%) Air Quality (4.6%) $1,000,000,000 Water Quality and Habitat (14.5%) Property Value Added (18%) $500,000,000 Recreation (22%) Heat Stress Mortality $- Reduction (35%) 1
  36. 36. Our Approach…. • Capture the first inch of each storm from 1/3rd of the City’s impervious cover over the next 20 years
  37. 37. Our Approach…. • Capture the first inch of each storm from 1/3rd of the City’s impervious cover over the next 20 years • Achieve continuous improvement
  38. 38. Green Infrastructure = Continuous Improvement 85% 80% Performance 75% 70% 65% 60% 55% 0 5 10 15 20 Time Centralized Storage Green Infrastructure Green/Transmission/Treatment
  39. 39. Our Approach…. • Capture the first inch of each storm from 1/3rd of the City’s impervious cover over the next 20 years • Achieve continuous improvement • The more change that occurs through normal urban renewal, the less it will cost
  40. 40. Philadelphia’s 2006 Stormwater Regs have already reduced runoff by (almost) 1 BG per year
  41. 41. Philadelphia Highlighted Stormwater Projects Submitted Stormwater Projects Combined Sewer Area
  42. 42. Highlighted Projects
  43. 43. The Radian • 39th St & Walnut St • 12,000 sq ft. Green Roof
  44. 44. The Radian
  45. 45. Wexford Science Center • 37th St & Market St • 34,000 sq ft Green Roof
  46. 46. Wexford Science Center
  47. 47. Drexel Millennium Hall • 34th St & Race St • 5,000 sq ft Green Roof
  48. 48. Drexel Millenium Hall
  49. 49. Our Approach…. • Capture the first inch of each storm from 1/3rd of the City’s impervious cover over the next 20 years • Achieve continuous improvement • The more change that occurs through normal urban renewal, the less it will cost • Use incentives to increase the rate of change
  50. 50. Create Financial Incentives for Better Land Management
  51. 51. Create Financial Incentives for Better Land Management Gross Area = 13.5 acres Imperv Area = 11.5 acres
  52. 52. Create Financial Incentives for Better Land Management Top 500 parcels in the combined sewered area make up 12.3% of total impervious area Gross Area = 13.5 acres Existing Charge = $ 5,000 Imperv Area = 11.5 acres New Charge = $ 30,000
  53. 53. Rewarding the Urban Form Gross Area = 24,000 sq ft Existing Charge = $ 56,500 Imperv Area = 24,000 sq ft New Charge = $ 1,400
  54. 54. Concept Design & Cost Analysis
  55. 55. Putting it all together • Green streets • Green homes • Green schools • Green commerce • Green institutions • Green alleys • Green parking
  56. 56. Overwhelming Public Support “I love the idea! Please give us a greener Philadelphia. It would make us healthier and happier all around.” - Response to the question, “Are you in favor of greening?” (PWD “Green Neighborhoods through Green Streets Survey.”)
