While many municipalities are implementing and advancing components of asset management for green stormwater infrastructure (GSI) assets, for example, developing asset inventories and maintenance protocols, few have made the leap from managing assets to asset management, in other words, creating and implementing an asset management plan. The Green Stormwater Infrastructure Asset Management Resources Toolkit (the Toolkit) was born out of the need to provide more specific guidance and case studies on how to incorporate GSI into asset management.
The development of Toolkit was funded by Green Infrastructure Leadership Exchange (“Exchange”) and involved a collaborative effort among six Exchange members: the City of Toronto, Ontario; City of Vancouver, British Columbia; City of Atlanta, Georgia; City of Portland, Oregon; Metropolitan Sewer District of Greater Cincinnati, Ohio; and City of Palo Alto, California, as well as two subject matter experts: the Southwest Environmental Finance Center (SWEFC) and the Green Infrastructure Ontario Coalition (GIO).
SWEFC developed a free, online Integrated Asset Management Framework for combining green and gray assets into asset management which was released in 2021. The GSI Asset Management Resources Toolkit project aimed to build upon this work by beta testing SWEFC’s Framework and applying it to GSI assets that are commonly used within the right-of-way: pervious pavement, bioretention planters, and stormwater trenches, as well as streams, which provide essential stormwater services. These asset types represent a cross section of assets ranging from entirely engineered/built (permeable pavement) to natural (streams), with bioretention planters in the middle.
The major goal of this project was to develop a toolkit that includes guidance on establishing a GSI asset management program and case studies sharing outcomes, tools, progress, challenges, and lessons learned from participating agencies developing their asset management plans for GSI.
