Online Resources, Photos and Talks from GSI Summit

This past February the City of Seattle was pleased to join Stewardship Partners, The Nature Conservancy, Washington Environmental Council, Washington State University, MIG-SvR Design, Boeing, Vulcan, and many other collaborators and sponsors to co-host the first Puget Sound Green Infrastructure Summit.

Resources, photos and talks from this Summit are now available on-line at:

Green Stormwater Infrastructure – A Key Tool to Cleaning Our Waterways

Green Stormwater Infrastructure (GSI) is a term being used more frequently in Seattle and the Greater Puget Sound area—and that’s a good thing. GSI is the use of natural drainage systems like rain gardens and cisterns to slow, capture, and clean polluted runoff before it harms our lakes, rivers, and streams. By mimicking the way forests manage rainwater, GSI also brings natural beauty and a host of other benefits to our neighborhoods and homes.

The science is clear:  polluted stormwater runoff from our roads and roofs is the greatest threat to water quality in Puget Sound and directly endangers our salmon populations. But by using green infrastructure, together with other smart urban strategies like street sweeping and forest protection, we can prevent this pollution and provide broader community value.  It’s a true win win.

That’s why Seattle has deepened its commitment as a national leader in this area by setting a goal to manage 700 million gallons of polluted runoff  with GSI annually by 2025. We’re committed to using natural approaches to manage stormwater wherever we can, because we know these approaches protect our waters and make our neighborhoods better.

In order to help catalzye innovative partnerships and accelerate GSI implementation across Puget Sound, the City of Seattle is pleased to join with Stewardship Partners, The Nature Conservancy, Washington Environmental Council, Washington State University, MIG-SvR Design, Boeing, Vulcan, and many other collaborators and sponsors  to co-host the first Puget Sound Green Infrastructure Summit.

The Summit will take place Feb. 24th from 9 am to 4:30 pm at the Mountaineers Club, and will bring together diverse leaders from government, academia, business, and non-profit organizations from across Puget Sound.  Participants will  map the strategic role of green infrastructure in our cities, towns and communities and in Puget Sound’s clean water future.

Reducing water pollution with green approaches

Polluted stormwater runoff is the leading water quality threat to Puget Sound, the City has released a draft citywide Green Stormwater Infrastructure Strategy, outlining plans to accelerate green approaches for preventing this type of water pollution.

Rainfall rushing off hard surfaces like roads and parking lots can overwhelm our piped drainage system and cause back-ups and combined sewer overflows. The runoff also carries pollution directly into creeks, lakes, and other waterways. Green stormwater infrastructure (GSI) prevents overflows and pollution much like a forest would – by slowing and cleaning the water, and either reusing it or allowing it to soak back through the soil. Examples of GSI include roadside bioretention swales and street trees that manage street runoff; raingardens and cisterns that manage roof runoff; and green roofs and permeable pavement that are self-managing.

The draft Strategy sets an interim goal of managing 400 million gallons of stormwater runoff annually with GSI by the year 2020, summarizes progress to date, outlines a set of strategies and planned investments for accelerating the adoption of GSI in Seattle, and articulates a two-year work plan for City of Seattle departments.

The draft 5-year GSI Implementation Strategy is available for public comment through August 26. For more information, contact Pam Emerson, Green Stormwater Policy Advisor,, 206.386.4507.

Open House Event for Environmentally Critical Areas

(re-posted from DPD’s blog)

Seattle has five environmentally critical areas such as wetlands and wildlife habitat areas. How do we protect these environmentally critical areas (ECAs)? DPD is hosting an open house event for the update to our ECA regulations on Wednesday, February 25, 5:30-7:00pm in the Bertha Knight Landes Room at City Hall.    

The presentation will explain what and where environmentally critical areas are, how we incorporate Best Available Science, and how the ECA regulations protect critical areas. Learn about the Growth Management Act and how it influences updates and changes to ECA regulations. This event will help guide the effectiveness of our ECA policies and regulations.

In Seattle, environmentally critical areas include the following: wetlands, fish and wildlife habitat conservation areas, geologic hazard areas, flood-prone areas, and abandoned landfills.

More information about the ECA update is here.
