Green Infrastructure

Viewing communities from above would reveal a network of green between the gray infrastructures of the streets, buildings and parking lots. This green is referred to as green infrastructure (GI). Associating greenspace with infrastructure implies that it is a basic requirement to support a community. By considering greenspace as part of the community’s infrastructure, it becomes part of a network of interconnected systems requiring a budget for regular maintenance, development, and improvement. 

Overall, green infrastructure strategies actively seek to understand, leverage, and value the different ecological, social, and economic functions provided by natural systems. Doing so guides efficient, sustainable land use and development patterns, and protects natural ecosystems. 

Most Vermont communities have village greens, parks, street trees, town forests, and open space; which were originally conceived to provide the community with amenities. These amenities were established without considering their provided ecological services or their role in forming a networked infrastructure. Viewed as green infrastructure, urban and community forests can improve quality of life in Vermont’s cities, towns and villages. This is ensured through comprehensive planning that connects, conserves, manages, and enhances the natural resources within green inftrastructure. Explore the following resources to learn more about the value of green infrastructure and planning for it. 

Green Infrastructure is a topic paper in Vermont's Land Use Planning Manual that provides an overview of green infrastructure and local implementation in Vermont.

Tree Canopy Assessments provides a top down approach to plan for protection and improvements of green infrastructure.

Green Infrastructure A website through the American Society of Landscape Architects (ASLA) provides a thorough overview of green infrastructure and resources.

The Green Infrastructure Name Game

In recent years green infrastructure has also been defined as, mostly notabely by the Environmental Protection Agency (EPA), a stormwater management strategy that uses or mimics natural processes. To help avoid confusion of the various GI definitions and related terms, Vermont's Green Infrastructure Roundtable provides the following definitions for use in Vermont:

Green Infrastructure is a wide range of multi-functional, natural, and semi-natural landscape elements located within, around, and between developed areas at all spatial scales. This includes everything from forests and meadows to wetlands, floodplains, and riparian areas.

Low Impact Development (LID)

Low Impact Development (LID) is an innovative land planning and design approach which seeks to maintain a site’s pre-development, ecological and hydrological function through the protection, enhancement, or mimicry of natural processes. There are many reasons to use LID, but stormwater management is typically the primary use.

Green Stormwater Infrastructure (GSI)

Green Stormwater Infrastructure (GSI) are systems and practices that restore and maintain natural hydrologic processes in order to reduce the volume and water quality impacts of the built environment while providing multiple societal benefits. Trees are the ultimate GSI.
