Low-Impact Development and Green Infrastructure Implementation: Creating a Replicable GIS Suitability Model for Stormwater Management and the Urban Heat Island Effect in Dallas, Texas

Buchholz, Nicole

The rapid expansion of developing cities has dramatically changed natural
landscapes, altering local ecosystem function characteristics. Changes in permeable surface through the expansion of roadways, parking lots, and other built structures has altered natural water flows, groundwater recharge, impacted water quality, and increased surface temperatures (i.e. the urban heat island effect). Green infrastructure (GI) and low-impact design (LID) mimic natural systems in order to mitigate these impacts, and have a myriad of social, environmental and economic benefits. Current literature on these design practices focuses primarily on the regulatory, managerial, perception, and financial barriers to integration. This thesis addresses the gap in the literature for technical and structural suitability through a replicable, GIS model, using the rapidly developing city of Dallas, Texas as a case study. The GIS model will integrate five key criteria in GI and LID suitability: land cover, tree canopy, soil, minority and poverty status, and land surface temperature (identifying “hot spots” of urban heat island effect). By providing a replicable GIS model that integrates traditional GI and LID purposes (stormwater management), with socio-economic factors, and emerging issues of climate variability (urban heat island effect), the analysis hopes to provide technical support for practitioners in urban areas and in order to increase the implementation of these
designs.
