Assessing value of natural assets for stormwater services

Saini Sakshi and Amanjot Singh, Credit Valley Conservation Authority, Mississauga, ON, Canada


Natural assets like wetlands, woodlands, open green spaces, have significant stormwater benefits, some of these being flood and erosion control, groundwater recharge, and pollutant control. Municipalities are interested in valuating stormwater services of these assets to better account for natural assets in their asset management plans. The Credit Valley Conservation (CVC) has undertaken a study to model natural assets using EPA-SWMM to quantify water quality and quantity control, and what equivalent stormwater infrastructure would be needed to provide the same control. This presentation will discuss the approach to modeling one or more natural asset features in the credit valley jurisdiction. Results from a modeling study may be shared.
