What is Green Infrastructure?
Green infrastructure uses natural hydrologic features to manage water and provide environmental and community benefits.
Learn More

Why Green Infrastructure?
By improving the environment and preserving open space, green infrastructure supports sustainable communities.
Learn More

Green Infrastructure for Climate Resiliency
Climate change is affecting us now. As different parts of the country become drier, wetter or hotter, green infrastructure can help improve community resiliency today and into the future.

How Can I Overcome the Barriers to Green Infrastructure? 
Many of the barriers to green infrastructure arise from unfamiliarity with green infrastructure approaches, and can be overcome by consulting the experience of municipalities and developers familiar with green infrastructure.

Green Infrastructure Case Studies

Green infrastructure first emerged as an alternative approach to stormwater management in the early 1990s. Since then, stormwater professionals have accumulated an extensive body of knowledge on the design of green infrastructure practices that improve the triple bottom line, and on the development of policies that support this approach.

Case studies offer a particularly effective way of sharing this body of knowledge. By telling the story of how green infrastructure was planned, designed, and built in a particular location, case studies illustrate how the concept of green infrastructure can be adapted to particular contexts. To view case studies from your region, click on the appropriate area in the map below. To view national compilations of green infrastructure case studies, scroll to the bottom of the page.

Performance
A wealth of research has examined the performance of green infrastructure in reducing the discharge of pollutants to receiving waters, removing air pollutants, and even reducing energy use.

Groundwater Impacts

Green infrastructure allows more water to soak into the ground than traditional drainage infrastructure. A growing body of research examines the ability of green infrastructure to restore groundwater recharge, as well as its ability to attenuate pollutants.
Learn More

Community-Scale Studies

EPA is conducting case studies in several communities to assess the effectiveness of green infrastructure in protecting water quality while monitoring social and economic impacts.
Learn More

Economics and Policy
Many studies have examined the role that economics and policy play in implementing green infrastructure concepts.
Learn More

Research Programs
EPA's Safe and Sustainable Water Resources program is one of a growing number of university and government programs engaged in research that supports the design and implementation of green infrastructure.

Green Infrastructure Library

Since the early 1990s, the scientific, regulatory, and development communities have gained a wealth of experience with the implementation and impacts of green infrastructure. Much of this experience is documented in articles, reports, and manuals – but few resources are available that collect all of these materials in one place. This page is intended to fill this gap. Here we present all of the documents cited throughout this website and many more publications that did not fit. We believe this collection represents the latest and most significant publications developed by the scientific, regulatory, and development communities on green infrastructure. To submit a publication to our collection, please e-mail the citation and document to Tamara Mittman

Stormwater Impacts
Urban Stormwater Impacts
The scientific literature addressing the impacts of urbanization on water resources is extensive and conclusive. Large areas of connected impervious cover and changes in land use dramatically increase the volume and rate of stormwater discharges – leading to increased pollutant delivery, flooding, and erosion as well as decreased groundwater recharge. The publications below document the impacts of urban stormwater on aquatic ecosystems and human health.

Principles of Green Infrastructure
The following reports discuss how green infrastructure can mitigate the effects of urbanization on water quality. The goal of green infrastructure is to manage the small, frequent storms that account for the most pollution. These reports explain the importance of small storms, and describe how we can preserve and mimic nature to manage these small storms.

Many green infrastructure practices manage stormwater by allowing it to soak into the ground as it would in a natural setting. This approach has the potential to restore groundwater recharge rates, but also has the potential to introduce pollutants into the subsurface. The reports and articles below examine both the ability of green infrastructure to increase groundwater recharge, and the ability of green infrastructure to treat infiltrated water.

Habitat Impacts
Preserving and restoring open space within and beyond urban areas can provide habitat for wildlife and increase urban biodiversity, particularly when these areas are managed to support a variety of native plant species. The resources below address the ability of green infrastructure at the site and city scale to provide habitat for diverse fauna.

Design Manuals

Many states, regions, and cities have developed design manuals explaining how to site, size, and construct green infrastructure practices. Most are targeted towards designers and engineers, but some are targeted towards the homeowner. The resources below include a sample of these design manuals, as well as a few publications on construction, maintenance, and lessons learned.
