Green Infrastructure


LID Design Competition   Brainerd Airport SEP

Green infrastructure is a form of Low Impact Development (LID) that utilizes vegetation and natural hydrologic processes to manage and treat stormwater. The goal of green infrastructure is to capture rainwater where it falls in urban spaces, providing benefits for both the community and environment. On the localized scale, rain gardens or bioretention ponds, wetlands, riparian zones, permeable pavement, green roofs, rainwater harvesting, sidewalk trees and urban agriculture are all examples of green infrastructure.

Green infrastructure is beneficial for both the environment and society as it catches pollutants and cleans water, decreases runoff volumes and adds aesthetic value to neighborhoods. On the regional scale, green infrastructure preserves, conserves and restores natural landscapes and is often connected to corridors for people and wildlife.

With aging infrastructure, increasing populations and a need for results that are collaborative and efficient with financial resources, green infrastructure is becoming the standard for stormwater management throughout the country. Whether encouraged by compliance, community activism or natural disaster response, communities are creating natural environments for proactive management of urban waters. As small as rain gardens or raised garden beds and as large as regional corridors or parks, green infrastructure endeavors are varied and individual.

You can help! Catch the rain at your house, support urban gardens, and dissipate or infiltrate the rain water hitting your property as much as possible.

Chattanooga's new stormwater ordinance financially incentivizes new and redevelopment sites to capture increased amounts of stormwater onsite. This new program supports the mindset that stormwater is not a nuisance, but a resource. Checkout Resource Rain and the Rain Management Guide (RMG), to see guidelines for new development design.

For more information on this topic, see the EPA or American Rivers definitions of green infrastructure.

Stay tuned and be patient with us. We are updating our site and will soon give you pictures of our endeavors and links to the challenges and many successes facing green infrastructure across the nation.
