Conventional stormwater conveyance systems have been primarily focused on removing excess runoff from urban and residential areas as quickly as possible. Conveyance practices have decreased the time of concentration of stormwater runoff, increased runoff volume and peak flow that together, create multifaceted problems on-site and downstream. Instead of rapid conveyance, scientific principles of ecosystem balance, including the concept of stormwater infiltration, are being emphasized as superior system management. This thesis will analyze and compare conventional conveyance strategies with on-site infiltration methods in an existing suburban residential subdivision in Athens-Clarke County, Georgia. Since the study site is post-developed, this research and design focus is on minimal site redesign to meet specific runoff limits that resemble the pre-developed landscape. The value in this research project will show that entire post-developed subdivisions can be revisited and corrected to meet pre-developed standards. With specific ecological design principles that imitate natural processes, conventional residential developments can be retrofitted to manage stormwater on site.
