Additional Benefits of LID
• Case Studies Analyzing the Economic Benefits of Low Impact Development and Green Infrastructure Programs (EPA, 2013)
• Reducing Stormwater Costs through Low Impact Development Strategies and Practices (EPA, 2007)
Reduced Construction Costs
• A 2008 study in Seattle found neighborhoods with LID practices increased property values by 3.5-5% (The Effect of LOD on Property Values, Water Environment Federation)
Increased Property Values
