“Retrofitting Our Legacy” is a new report from TNC Washington that offers five common-sense policy strategies for cities and counties to ramp up their use of green solutions to tackle runoff pollution at the scale of our road system.

The Stormwater Heatmap imperviousness data layer now represents the most detailed rendering ever made of impervious surfaces in the Puget Sound region.

Workforce development is a roadblock in the effort to implement nature-based solutions for climate resilience within Washington State and across the country. To address this challenge, experts and collaborations have identified challenges and solutions for workforce development within the green stormwater infrastructure (GSI) field.

Researchers at the University of Washington use a technique known as Q-methodology to understand perspectives on stormwater solutions among community members and practitioners.

Researchers at the University of Washington use a method called Multi-Objective Prioritization to understand how stormwater solutions can be used to benefit both people and salmon.

Researchers at the University of Washington use a method known as Qualitative Network Modeling to understand the interactions between stormwater, stormwater solutions and the surrounding environment.

It has been 50 years since the Clean Water Act was passed and while substantial progress has been made for the health of waterways, people, and the planet there is still more work to do. Green infrastructure such as bioswales and rain gardens are one tool that can help the Puget Sound region support people and Salmon.

Saving salmon and solving stormwater is a complicated business, but green infrastructure tools like rain gardens provide a first step to reducing the influx of toxins into local waterways.

Local and national partners work together to produce adetailed toolkit that support a healthy urban tree canopy in Central Puget Sound – and a model that regions around the country can replicate.

Trees provide a multitude of benefits in our urban environments, but as climate change progresses choosing the right tree will become increasingly important.

The Stormwater Heatmap harnesses the power of big data to model where stormwater pollution is generated across the landscape — helping public municipalities plan for the future. As a living tool continually updated with the latest data, it’ll be exciting to see how communities, academics, and policymakers can use this to create lasting impact.

A neglected parking lot has transformed into vibrant urban agricultural land and a leading example of how green stormwater infrastructure can be implemented at the community level.

Seven years later, and over $200 million dollars spent in Floodplains by Design alone, we are seeing a new level of resilience, creativity and impact in our floodplains across the state.
