Which description best defines green infrastructure?

• A. A policy that mandates dense zoning within the urban core.
• B. Network of natural and semi-natural elements that deliver ecosystem services; benefits include stormwater management, cooling, biodiversity, recreation.
• C. A system of gray infrastructure focusing on pipes and culverts.
• D. An aesthetic plan for designing parks.

Answer: (B)

Green infrastructure is a network of natural and semi-natural elements that deliver ecosystem services in urban areas. The essential idea is to use natural processes to manage water, cool cities, support wildlife, and provide opportunities for people to enjoy open spaces. This approach contrasts with gray infrastructure, which relies on pipes and concrete to move water. It’s more than just parks for aesthetics; it’s an integrated system where connected green and blue spaces work together to provide multiple benefits, including stormwater management, cooling, biodiversity, and recreation.
