Urban stormwater contributes to the deterioration of surface water quality across Canada. Low impact**development stormwater management technologies are an increasingly popular approach to decrease the impacts**of stormwater on the watershed. Bioretention systems, which are permeable vegetated road side depressions**designed to retain and improve the quality of stormwater, are one such technology for which demand is rapidly**growing. C.F. Crozier & Associates, a consulting engineering company focused on land development and water**resource projects, has identified the need for optimization of the composition of the engineered soil media used in**bioretention systems with respect to its ability to retain and remove contaminants from stormwater. Western**University researchers will combine evaluation of existing field-scale bioretention systems with advanced soil**column laboratory experiments to test and develop new bioretention soil compositions that address key**deficiencies identified in the performance of field-scale systems. C.F. Crozier & Associates will apply the project**findings in the design of future bioretention system installations to improve system performance, longevity and**reduce maintenance costs. This research initiative will help position C.F. Crozier & Associates as leaders in the**design and implementation of LID technologies. An elevated company image will enable C.F. Crozier & Associates**to retain more project contracts, attract new clients, employ additional highly qualified personnel, and ultimately**result in increased company revenues.
