Eliminates untreated storm water and creates zero runoff. Directly recharges groundwater
Mitigates “first flush” pollution
Protects streams, watersheds, and ecosystems

Mimics the drainage and filtration of bioswales and natural soils Reduces surface temperatures and heat island effects
Provides a higher albedo surface reflectivity index (0.35 or higher) Eliminates need for expensive collection and detention systems

A pervious infrastructure is much more profitable for the developer
Eliminates time consuming and costly storm water detention vaults and piping systems Eliminates the cost of curb and gutter installations
