There has been alot of talk about "green infrastructure" over the last several years--and communities all across the nation are slowly moving towards this more natural approach.
At the largest scale, the preservation and restoration of natural landscape features (such as forests, floodplains and wetlands) are critical components of green stormwater infrastructure. By protecting these ecologically sensitive areas, communities can improve water quality while providing wildlife habitat and opportunities for outdoor recreation. On a smaller scale, green infrastructure practices include rain gardens, porous pavements, green roofs, infiltration planters, trees and tree boxes, and rainwater harvesting for non-potable uses such as toilet flushing and landscape irrigation.
In Pennsylvania, these ideas are really starting to take hold. The Philadelphia Water Department is at the forefront of using green solutions to meet the challenges presented by rain, and we're thrilled to be working to document and share the many innovative practices that are being put into place.
This 3 minute promo offers an exciting vision of what a City can be:
We've developed an entire series of videos in partnership with PWD and others to show not only how the cityscape is changing, but how neighborhoods are being popisitively impacted by the Green Tools that are being used to deal with rainwater. Below is a small sampling; go to Case Studies to check out the rest:
