The incorporation of vegetated roofs into a region's stormwater management plan may be an efficient method of managing flooding issues and combined sewer outflow system maximum loads. Currently, vegetated roofs are not widely used within New England as a common stormwater Best Management Practice. My research explores vegetated roof stormwater retention performance in the Seacoast New Hampshire region. This research experimentally quantified the complete water balance of a vegetated roof system in an outdoor, rooftop setting, developed a predictive vegetated roof stormwater retention model and modeled retention for an eight year period from 2002 to 2009. This eight year model was applied to downtown Portsmouth, NH by identifying the roof top area potentially capable of supporting vegetated roofs and quantifying the volumetric stormwater reduction.
