Short summary

The goal of this study was to compare how differences in urban stream restoration and sanitary infrastructure affect sources and fluxes of water and nutrients. Stream restoration reduced peak discharge and lowered nutrient export compared to unrestored streams, but was similar to a stream with upland stormwater management. The primary source of nitrate at all sites was leaky sanitary sewers, suggesting that combining stream restoration with sanitary pipe repairs may help reduce nutrient loads.
