Green City... Clean Water
- 1. Green City… Clean Water Blending interests of land and water Howard M. Neukrug, PE Director, Office of Watersheds City of Philadelphia
- 2. Philadelphia Water Department Office of Watersheds • An integrated utility: • Drinking Water • Wastewater • Stormwater • A new integrated approach: • Land • Waterways • Infrastructure • Community
- 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. 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)
- 6. 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

- 31. The old approach to managing water
- 37. 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
- 39. There are significant issues ahead of us for improving the water environment PLUS: LTCPU, 308 letter, state COA, new permits
- 41. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer Photo: Black & Veatch
- 42. Our Approach for investing in CSO reductions • Keep stormwater out of the sewer • Spend capital dollars above the ground, not below it
- 50. 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
- 54. 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
- 56. 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
- 57. 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%
- 58. 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
- 59. Triple Bottom Line Economic/Environmental/Social Benefits • Costs • Ecological Benefits • Recreation • Heat Stress Mortality • Energy Savings • Air Quality • Carbon Footprint • Aesthetics • Jobs • Property Value
- 60. 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

- 62. Our Approach…. • Capture the first inch of each storm from 1/3rd of the City’s impervious cover over the next 20 years
- 63. 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
- 64. 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
- 65. 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
- 66. Philadelphia’s 2006 Stormwater Regs have already reduced runoff by (almost) 1 BG per year
- 67. Philadelphia Highlighted Stormwater Projects Submitted Stormwater Projects Combined Sewer Area
- 69. The Radian • 39th St & Walnut St • 12,000 sq ft. Green Roof
- 70. The Radian
- 71. Wexford Science Center • 37th St & Market St • 34,000 sq ft Green Roof

- 75. 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
- 76. Create Financial Incentives for Better Land Management
- 77. Create Financial Incentives for Better Land Management Gross Area = 13.5 acres Imperv Area = 11.5 acres
- 78. 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
- 79. Rewarding the Urban Form Gross Area = 24,000 sq ft Existing Charge = $ 56,500 Imperv Area = 24,000 sq ft New Charge = $ 1,400
- 80. Concept Design & Cost Analysis
- 81. Putting it all together • Green streets • Green homes • Green schools • Green commerce • Green institutions • Green alleys • Green parking
- 82. 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.”)
