Hydrology Environmental Management Social Research hydrology green infrastructure stormwater management stormwater retrofit water quality social survey Impervious surfaces in urban environments lead to greater runoff from storm events, overwhelm storm sewer systems, and degrade aquatic ecosystems. Disconnecting impervious surfaces from storm water systems and redirecting the flow to decentralized green infrastructure treatments can lessen the detrimental effects on urban streams. Most research on green infrastructure has focused on the performance of individual elements, whereas this project addressed the question of hydrologic impacts and pollution reduction of street-scale investments using green infrastructure, such as front yard rain gardens, street side bioretention gardens, and rain barrels. The West Creek Watershed is a 36 km2 subwatershed of the Cuyahoga River that contains ~35% impervious surface. Before-after-control-impact design paired two streets with 0.1-0.2 ha. lots and two streets with 0.05-0.075 ha. lots. Flow meters were installed to measure storm sewer discharge pre– and post- green infrastructure implementation. Peak discharge and total storm volume have been reduced with the addition of green infrastructure. Results for centroid lag-to-peak, centroid lag, lag-to-peak, and peak lag-to-peak show that lag times increased on the treatment streets. For peak discharge, total storm volume, and lag time, the presence or absence of underdrains from the design of the green infrastructure appeared to have an effect on the results. Water samples collected at the end of one set of treatment and control streets’ storm sewers were analyzed for heavy metal (Fe, Cu, Mn, Ni, Pb, and Zn) concentrations using ICP-OES. The pollution reduction potential of the green infrastructure treatments could not be determined due to the lack of pre-treatment sampling. However, concentrations of trace metals on both the treatment and control street were on the low end for typical urban runoff. Magnetics sampling concluded that anthropogenic inputs were present in both tree lawns and bioretention gardens. A survey of homeowners of both treatment streets was used to contribute to the understanding of social acceptability of large-scale green infrastructure implementation and the drivers of homeowner participation. Differences in attitudes, perception, and behaviors toward green infrastructure and stormwater management were observed between residents with green infrastructure on their property versus those without. Ultimately age, education, and years lived in home were the largest predictors to positive attitudes and perceptions toward green infrastructure and its implementation to help with stormwater management. 2015-04-20 English text Kent State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=kent1429133256 http://rave.ohiolink.edu/etdc/view?acc_num=kent1429133256 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
