Abstract:Temple and Villanova universities collected monitoring and assessment data along the I-95 corridor to evaluate the performance of current stormwater control design and maintenance practices. An extensive inventory was developed that ranks plants in the basins according to their health and location. Three plant species performed poorly in bioretention design and alternatives are proposed. Grab samples were collected for storms approximately monthly and analyzed for a variety of road runoff constituents. Although a full year of data was not yet available, annual loading for total suspended solids (TSS) and nutrients were estimated. LiDAR data helped show that variations in basin performance occurred due to changes in stormwater capture during construction. Simulated runoff tests (SRTs) were conducted to study response during a large volume event. These SRTs were valuable in quantifying drainage areas and improving monitoring strategies. Recommendations are provided on hydrologic design, potential contaminant mobility, planting, and maintenance.
