Green Infrastructure Federal Collaborative

In May of 2021, EPA launched the Green Infrastructure Federal Collaborative. This cooperative effort fosters engagement and cooperation between agencies that actively work to promote the implementation of green infrastructure.

Collaborative members work closely to align knowledge and resources to build capacity for green infrastructure implementation. These coordinated efforts provide a platform to publicize the multiple environmental, economic, and social benefits of green infrastructure. In addition, the collaborative seeks to facilitate strategies that foster climate resilience and encourage the equitable implementation of green infrastructure in all communities.

Background

The Water Infrastructure Improvement Act of 2019 (pdf) sparked the formation of the federal collaborative by directing EPA to coordinate efforts with federal, state, tribal, and local governments to increase the use of green infrastructure, providing an impetus for collaborative efforts to continue to evolve. Although EPA primarily uses the term "green infrastructure" as defined under the Clean Water Act, other government and nongovernmental organizations use other terms to describe the similar nexus of nature and man-made systems:

  • nature-based solutions
  • engineering with nature
  • natural infrastructure
  • green stormwater infrastructure
  • low-impact development

The first of these listed terms, nature-based solutions, is an umbrella term that 193 member nations agreed upon in March 2022 at the Fifth United Nations Environment Assembly. On November 8, 2022, the White House released a report titled Opportunities to Accelerate Nature-Based Solutions: The Roadmap for Climate Progress, Thriving Nature, Equity, and Prosperity (pdf). Developed in partnership with Green Infrastructure Federal Collaborative members, the report provides five recommendations to accelerate nature-based solutions to confront climate change and other major challenges. A companion to the report, the Nature-Based Solutions Resource Guide (pdf), includes 30 case studies of federal agencies supporting green infrastructure, as well as more than 170 knowledge resources, tools, guidance, and technical assistance opportunities.

EPA defines nature-based solutions as actions that protect, conserve, restore and sustainably manage natural or modified ecosystems. They use natural features or processes to address public health and environmental challenges while providing multiple benefits to people and nature. Visit the Green Infrastructure Resources page for other EPA programs that promote these types of solutions.

As nature is seen as a critical infrastructure that provides fundamental services to protect human health, restore our ecosystems, and create resilient communities, the use of "nature-based solutions" across federal programs is common. Nature-based solutions can encompass a wide range of actions that may include planning, design and maintenance of engineering practices that restore, use or enhance natural processes (e.g. green infrastructure, agricultural conservation practices, coastal restoration) and/or protect natural features to preserve ecosystem function (e.g., wetlands, forests, riparian areas, coral reefs).

In 2023, FEMA and EPA updated a Memorandum of Agreement (MOA) to work together on several fronts including conducting benefit analyses of nature-based solutions for building long-term resilience.

The U.S. Army Corps of Engineers has an initiative, Engineering With Nature®, to align processes of nature with engineering to provide more sustainable delivery of economic, social and environmental benefits associated with infrastructure.

The Department of Interior released a Nature-Based Solutions Roadmap (pdf) to provide staff with consistent and credible information about nature-based solutions, such as what benefits they are likely to provide, example projects, and additional resources for project planning, construction, and monitoring.

Federal Funding Resources

Fall 2024 Navigating Technical Assistance for Green Infrastructure and Nature-Based Solutions

The Green Infrastructure Federal Collaborative is presenting a series of technical assistance opportunities for green infrastructure and nature-based solutions. These technical assistance opportunities are free and available for assessments, designing and planning green infrastructure projects. They can also provide general technical assistance for navigating funding options, stakeholder engagement and project visioning.

Fall 2024 Federal Funding Opportunities Webinar

Navigating Federal Funding for Green Infrastructure and Nature-Based Solutions Table

The Green Infrastructure Federal Collaborative understands that one of the barriers accessing federal funding is the complexity of navigating the available opportunities. To support communities, the Collaborative compiled and periodically updates the Navigating Federal Funding for Green Infrastructure and Nature-Based Solutions (pdf) table, which is a comprehensive list of green infrastructure federal funding opportunities.

Common Terms

When applying for federal funding and technical assistance it is important to understand which terms are specified in each Notice of Funding Opportunity or Request for Applications. Below are examples of various terms Green Infrastructure Federal Collaborative members use.

Agency Used Term(s)
FEMA Nature-Based Solutions
U.S. Army Corps Engineering with Nature and Nature-Based Solutions
USDA Conservation, Urban Forests and Restoration Practices
Department of Defense Nature-Based Solutions and Natural Infrastructure
Housing and Urban Development Green Infrastructure
General Services Administration Green Infrastructure
Department of State Green Infrastructure
EPA Green Infrastructure, Nature-Based Solutions and Low Impact Development
NOAA Green Infrastructure and Coastal Restoration

Department of Defense Resilience Project Funding Guide

On April 11, 2023, the U.S. Department of Defense Readiness and Environmental Protection Integration Program (REPI) (pdf) released the 2023 Resilience Project Funding Guide (pdf).

In coordination with federal agencies of the Green Infrastructure Federal Collaborative, REPI created a guide that provides 27 funding programs for nature-based solutions to improve resilience in communities and military installations. It contains a calendar, descriptions, eligibility requirements, and application information for each funding program. It also aligns each program with climate hazard categories: Drought, Wildfire, Coastal Hazard, Riverine Flooding, and Land Degradation.

Federal Permitting

Federal Permitting and Environmental Reviews for Nature-Based Solutions: A Best Practices Guide (pdf) (5.6 MB, January 2025, EPA 833-R2-4002)

The GIFC developed this guide to identify ways to accelerate federal permitting and environmental reviews for nature-based-solutions (NBS) projects. This document is intended to provide federal agencies involved in the review of NBS projects with an overview of the federal permitting and environmental review processes related to NBS implementation; best practices recommendations; and examples of NBS projects and successful federal agency permitting networks that have navigated and streamlined these reviews and processes.

Navigating Federal Funding for Green Infrastructure and Nature-Based Solutions

During this webcast, members of the Green Infrastructure Federal Collaborative discussed funding and technical assistance opportunities that advance the implementation of green infrastructure and nature-based solutions. Attendees learned how federal programs are helping build vibrant and resilient communities with programs that support designing, constructing, and maintaining green infrastructure. Breakout sessions hosted by Collaborative members provided attendees with the opportunity to pose questions and interact directly with relevant federal agencies.
