1  Threats to Water Resources: Polluted Stormwater Water Resource Congress October 2014

2  Founded in 1973 to protect and restore America’s rivers  Headquartered in DC, American Rivers has offices across the country and more than 100,000 supporters, members, and volunteers nationwide

3 Why does Stormwater matter?

4 Credit: Conservation Trust for North Carolina

5 Runoff: a growing problem Development rates outpace population growth

6 Hydrological Impacts of Increased Runoff More Frequent F looding

7 Hydrological Impacts of Increased Runoff Credit: NRCS Increased Flood Peaks

8 Hydrological Impacts of Increased Runoff Lower Baseflow

9 Goal of Stormwater Management: Restore Natural Hydrology

10 Where is the Water Quality Management?

11 Traditional Infrastructure Modern Infrastructure

13 Environmental Economic Social Triple Bottom Line Analysis Recreational use Energy savings Improved air quality Fewer heat related fatalities Less time spent in traffic Green jobs Benefits of a Green Approach

18 Environmental Economic Social Triple Bottom Line Analysis

19 Cost-Effective Infrastructure Investments  Avoided costs at site and project levels  Reduced infrastructure, land costs  Community scale cost- efficiencies lower cost/gallon removal  Quantifiable benefits (offset costs, add value)  Likely lower O&M costs (less capital intensive)

20 Energy Savings, Fiscal Efficiency  Street trees shade, cool buildings, reduce heat loss. Improve energy efficiency by 5- 10%  Green roof energy efficiency gains can exceed 10%  Reduced demand reduces transport & treatment costs Photo: Mahan Rykiel Associates Inc.

21 Photo: Adam Kurbin Capturing Runoff Reduces Cost of Localized & Regional Flooding  2011 $ 8.41 billion flood damages  25% due to urbanized flooding  Long term indirect costs  Green infrastructure effective on multiple levels

22 Reducing Public Health Threats

23 What Is It Worth? Quantifying the economic value of local benefits

24 National Green Values Calculator Compares green & conventional ‘grey’ infrastructure: hydro impact life cycle costs benefits Adaptable to local ordinance compliance greenvalues.cnt.org

26 Valuing Green Infrastructure: How does it work? This guide focuses only on benefits – It’s not a cost/benefit analysis  Two step process – 1. Quantification 2. Valuation  Focus of equations on 4 areas 1. Water 2. Energy 3. Air Quality 4. Climate Change

27 Introducing the Market : the Emergence of Stormwater Credits  Alternative way of complying with on-site performance standard : DC  Credits against stormwater fee : Philadelphia

28  EPA estimates approximately $188.4 billion in capital investments needed for stormwater infrastructure  This doesn’t even include O&M, local needs or population growth  The size investment would generate:  $265.6 billion in economic activity Economic Impact Green Jobs
