On May 25th, SBN’s GSI Partners and DVGBC hosted the first of two peer-to-peer symposia to convene local industry professionals for a facilitated conversation around dynamic performance aspects of GSI. Truly green stormwater infrastructure (GSI), i.e. the vegetated practices, are systems that demonstrate the dynamic relationship between water, soil, and plants.
 
The first symposium explored technical aspects of soil performance as it relates to stormwater management.  Barrett Kays, Ph.D. presented findings from his research on sand-based structural soils and on enhanced infiltration through amending site soils. Tim Craul (Craul Land Scientists) presented a case study of Central Green, touching on site specific challenges and comparing and contrasting the soils approach with other sites he has worked on in the Philadelphia region.  Mark Highland, President of member firm, Organic Mechanics Soil Company, moderated.  The presentations were followed by a short tour of Central Green led by Kate Childers of Pennoni and Sarah Astheimer of James Corner Field Operations.  
 
Stay tuned for more information about the second event, which will be held in late June. 

The event series will culminate in a Fall 2016 release of a precedent library of exemplary GSI designs, systems, and approaches that will be used as a tool to help inform the approval of additional vegetated and innovative stormwater management projects in Philadelphia, and as a resource for industry professionals and other stakeholders to help increase the collective understanding of the dynamic capacity of GSI. The precedent library is being developed for the Sustainable Business Network’s GSI Partners in conjunction with DVGBC and a consultant team consisting of Meliora Design, Andropogon Associates, Roofmeadow, and SITE Green Solutions, with support from Indigo JLD.
