Abstract
Vegetative roofs’ capacity to decrease the rate and volume of roof runoff is dependent on a range of factors related to climate and roof system characteristics. An experimental setup constructed by the author at Virginia Tech is testing the effects of system depth and presence of vegetation on runoff reduction. Data collection began in April 2011, and results from selected storms will be presented. The expected outcome of the study is a model that will enable vegetative roof system designers, building owners, and policymakers to more confidently anticipate the benefits of installing modular vegetative roof systems for stormwater mitigation.
