What is Green Infrastructure?Green infrastructure techniques are cost-effective, sustainable strategies that manage stormwater where it falls, through natural processes such as infiltration and evapotranspiration.

Why is NYC implementing it?New York City Department of Environmental Protection (DEP) is leading the New York City Green Infrastructure Program, a multi-agency investment to improve water quality and distribute the co-benefits that come along with green infrastructure across the city.

This program aligns with other citywide greening initiatives, such as Local Laws No. 92 and 94 of 2019, which require certain roof installations and replacements to include solar or green roofs. Together these programs seek to strengthen the community’s resilience to climate change and improve New York Harbor’s water quality.

Available Financial ResourcesDEP and others are providing financial incentives for installing green infrastructure, or stormwater source controls, on private property in New York City.

• Green Infrastructure Grant Program providesfunding for green roof retrofits with 5,000 SF ormore of planted area.

• Green Roof Tax Abatement provides a one-timeproperty tax abatement for properties that have greenroofs.

• Private Incentive Retrofit Program aims to retrofitproperties 50,000 square feet or larger with greeninfrastructure through a contractor incentive.

• NYS DEC Green Innovation Grant Program (GIGP)supports projects across New York State that utilizeunique stormwater infrastructure design and createcutting-edge green technologies.

How does Green Infrastructure work?

GREEN ROOFS ARE VEGETATED SYSTEMS BUILT ON ROOF TOPS, DESIGNED TO CAPTURE AND MANAGE STORMWATER RUNOFF BEFORE IT ENTERS THE SEWER SYSTEM.

PERMEABLE PAVERS OR POROUS CONCRETE ALLOW FOR WATER TO SEEP IN BETWEEN THE PAVING MATERIALS AND BE ABSORBED INTO THE GROUND.

SUBSURFACE STORMWATER SYSTEMS ARE PERFORATED STRUCTURES SURROUNDED BY GRAVEL THAT PROVIDE TEMPORARY STORAGE OF STORMWATER RUNOFF UNDERGROUND AND HAVE INFILTRATION CAPABILITIES.

BIORETENTION SYSTEMS ARE RAIN GARDENS AND BIOSWALES, WHICH REDUCE FLOODING BY ALLOWING RAIN TO BE NATURALLY ABSORBED INTO THE GROUND.
