Environmental Economic Social Triple Bottom Line Analysis
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)
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.

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