What is Green

Infrastructure?

Green Infrastructure (GI) is naturally-occurring vegetation and

soils that mimic natural ecological processes to aid in water

management and create healthier ecosystems.

Poor stormwater

management leads to�.

● Downstream flooding

● Habitat destruction

● Infrastructure damage

● Combined Sewer Overflows

● Contaminated waterways

Good GI leads to*.

Lower energy consumption, lower costs

Reduces flooding and infrastructure to near zero

Cleaner waterways

Retention vs. Detention
