Using Green Infrastructure to Manage Stormwater

DEP has a broad citywide effort to better manage stormwater using a variety of innovative, sustainable green infrastructure. Improved stormwater management is an important component of Mayor Bloomberg's PlaNYC initiative and Sustainable Stormwater Management Plan.  Green infrastructure, or source controls, are a set of techniques that detain or retain stormwater runoff through capture and controlled release, infiltration into the ground, vegetative uptake and evapotranspiration thereby reducing the need for end-of-pipe stormwater storage and treatment systems.

Benefits of Green Infrastructure

Benefits of Green Infrastructure
Green infrastructure substantially advances Mayor Bloomberg’s PlaNYC, a multi-pronged sustainability effort that will reduce the urban heat island effect, enhance recreational opportunities, improve quality-of-life, restore ecosystems, improve air quality, save energy, and mitigate and adapt to climate change. These goals, as well as improved water quality, are substantially advanced by green infrastructure in ways that traditional grey infrastructure cannot match.
