Abstract
The goal of this case study was to evaluate the effectiveness a 275 m regenerative stream restoration design to mitigate stormwater runoff in a highly urbanized watershed. The restoration resulted in a wide, wetland-like floodplain, comprised of a rock base that was overtopped with a filtration media (approximately 30% woodchips and 70% topsoil). The creation of the floodplain-wetland complex in tandem with filtration media lead to increased storage capacity and an increase in hyporheic exchange within the system. Significant reductions were found for the storm hydrograph parameters volume, peak discharge, and time to peak. Reductions in baseflows were also noted for summer and fall months. Riparian (and in-channel) vegetation played a significant role in storm hydrograph and baseflow changes, likely the result of increased evapotranspiration rates and channel roughness. While water quality was assessed in a limited capacity, preliminary results are positive and are suggestive that the design promotes denitrification.
