Abstract
One of the factors that threaten freshwater quality is the input of anthropogenic nutrients, a problem heightened in urban areas with abundant impervious surfaces. The implementation of green infrastructure (GI) allows stormwater runoff to be filtered before entering waterways, reducing nutrient input. However, such installations can have the counter intuitive effect of gentrification, termed the ‘green space paradox’. The effects of the ‘green space paradox’ can be avoided through careful planning and targeted goals of GI execution. This study looks at the implementation of GI in the Arthur Kill watershed in New Jersey which covers an area of 337 square km and has 95% residential, commercial, and industrial developed space. The curve number method is utilized to determine the amount of stormwater runoff and nutrient loading historically observed in the watershed. Bias corrected rainfall projections from four Global Climate Models are used to determine projected stormwater runoff and nutrient loading. Results determine optimum GI execution and placement in the watershed to reduce stormwater runoff and nutrient loading with the added benefit of reducing the ‘green space paradox’.
