Green Stormwater Infrastructure

We provide guidance for modest to grand transformations of Seattle’s urban landscape, creating green elements that welcome the rain – storing, draining, and cleaning it.

In 2013, the City Council and the Mayor directed city departments to work together to achieve Seattle’s goal of managing 700 million gallons of stormwater runoff using green infrastructure.
