NTM Stormwater Designer Amanda Hess, PhD, EIT presented at the 2017 Villanova Urban Stormwater Partnership (VUSP) Pennsylvania Stormwater Symposium on Wednesday, October 11, 2017. The symposium took place at Villanova University from October 10-12. The purpose of the symposium is to advance the knowledge and understanding of sustainable stormwater management for those dealing in all aspects of planning, design, construction, maintenance, operations, and regulatory compliance.
Amanda’s presentation, “Rain Garden Evapotranspiration Accounting Method,” focused on the current rain garden design in Pennsylvania and how the current approach does not consider dynamic processes, such as infiltration and evapotranspiration (ET). The current practices encourage an overdesign of rain gardens, which is not sustainable and results in fewer rain gardens being implemented. She discussed a proposed accounting method with results that can easily be incorporated into current rain garden design in PA to provide more accurate and higher void space credits.
Amanda also served as the moderator for a technical session on “Leveraging Green Infrastructure (GI).” NTM Senior Project Manager Mark D. Bowen, PE, CFM also served as moderator for a technical session on “Vegetated Infiltration.”
