Abstract
Although green infrastructure is accepted as a technique to reduce runoff and improve water quality, questions remain about its effectiveness in the field. This study has three components: a quantitative assessment of runoff reduction in two municipal parking lots, a qualitative assessment of design features, and an analysis of the history of the Tannery Brook to provide context for modern restoration. In fall 2016, two municipal parking lots in Kingston, NY were reconstructed with several green infrastructure practices. Water level within 2 rain gardens, 3 bioretention areas, and 5 dry wells was measured for 28 storms May-November 2017 to better understand runoff reduction. Although certain maintenance issues have been identified, the practices are overall performing very well. The Tannery Brook is an excellent case study of the ways that we have perceived and managed water in cities over time. Its history and present state provide context for modern stream and stormwater management. By sharing the Tannery Brook's story, we can better understand urban waterbodies and what it might take to improve them in the future.
