Challenges / Problems Addressed
• Urban flooding due to stormwater runoff
• Water pollution from surface contaminants
• Urban heat island effect due to conventional impermeable surfaces
Context / Scope of Application
• Urban and suburban environments
• Roads, parking lots, sidewalks, bike paths, and driveways
NBS Solution
• Pavements designed with porous materials (e.g., porous asphalt, permeable pavers, pervious concrete) that allow water to infiltrate the ground
• Reduces surface runoff and filters pollutants before reaching groundwater
Impact / Success Indicators and Results
• Reduction in surface runoff and flood risks
• Improvement in water quality through natural filtration
• Enhanced groundwater recharge
