Abstract
Stormwater management has been an innovative research topic in the past decade. The use of bioswales or permeable concrete is an advantageous way for managing stormwater pollution through Best Management Practices (BMPs). Permeable pavements are beneficial as they save space, reduce impervious drainage area, and allow more traffic in populated areas. Bioswales also provide great benefits as they are visually appealing, require less maintenance, and are generally cheaper. In this work, we compared traffic and drainage performance for an existing bioswale design and proposed permeable pavement designs. Traffic and drainage data were obtained from the City of Fremont and Alameda County Flood Control District (ACFD). Average daily volumes, different storm events, and three design alternatives are modeled in SYNCHRO and EPA-SWMM to understand the performance of permeable pavement and bioswales under different traffic and storm loads with and without maintenance. It was found that utilizing a hybrid design of about 50% permeable gave the best performance.
