394567 - Performance Metrics of GSI in 23 American Cities in the 100 Resilient Cities Network

Tuesday, June 5
10:30 AM - 12:00 PM
Location: Mirage Room

There are 23 US cities in the Rockefeller Foundation funded 100 Resilient Cities Network. The 23 US cities are: Atlanta, Berkley, Boston, Boulder, Chicago, Dallas, El Paso, Honolulu, Los Angeles, Louisville, Miami, Minneapolis, Nashville, New Orleans, New York city, Norfolk, Oakland, Pittsburgh, San Francisco, Seattle, St. Louis, Tulsa, Washington DC. Not all cities list stormwater management as their primary resilience concern, but each has implemented some form of Green Stormwater Infrastructure (GSI). This study asked two questions. First - what policy framework drives the design standards in the resilient cities? ARUP’s criteria for resilience, developed for the 100 Resilient Cities network was contrasted with existing design standards for GSI. Second – what are the performance metrics that are used to assert the resilience of these installations. Five GSI practices were assessed for each of the 23 cities, and reviewed for the criteria the cities are using for performance measurement. These were contrasted with recommendations of GSI performance metrics found in literature, ranging from severity of failures, maintenance, repair frequency, repair rates, etc.

A number of cash starved municipalities are looking to GSI as a climate resilient, low-cost alternative to traditional stormwater infrastructure. However, there is no uniform engineering standard to design these systems to be climate resilient or formal metrics to assess their performance or resiliency. This work provides recommendations based on practices in the resilient cities in the US.
