Urban Stormwater Impacts Water Quantity: Urban Flooding Costly interruptions of urban transportation and other activities. Damage to property and infrastructure. Water Quality: Urban stormwater is listed as the primary source of impairment for 13% of all rivers, 18% of all lakes, and 32% of all estuaries. In 2010, stormwater caused more than 8,700 beach closing and advisory days; sewage spills and overflows caused more than 1,800. Hydrologic, Geomorphic, and Biological Impacts: Increased stormwater volume and velocity causes flooding, reduced bank stability, and channel erosion. Impaired habitat and water quality impact fisheries and shellfish harvesting.
Approaches to Managing Stormwater The Conveyance Approach Rapidly remove stormwater from impervious surfaces to receiving streams by way of engineered drainage systems (e.g., culverts, storm drains, and channelized streams). The Infiltration Approach () Retain stormwater as close as possible to its originating source(s), infiltrating as much as possible into the soil by using best management practices and strategies.
Comprehensive Urban Stormwater Treatment & Analysis Tool is a decision support system to systematically evaluate the benefits (runoff and pollutant load reductions) and costs associated with various GI implementation scenarios (location, number, type, and size of GIs), and identify the most costeffective options for achieving desired flow mitigation and pollutant reduction. Answers Key Questions: o How effective are GIs (LIDs and BMPs) in reducing runoff and pollutant loadings o What are the most costeffective solutions for meeting water quality and quantity objectives? Low Impact Development/BMP Siting Tool o And where, what type, and how extensive should the GIs be?

What are BMPs, LIDs, SUDS? What is? is a decision support system that assists stormwater management professionals with developing and implementing plans for flow and pollution control measures to protect source waters and meet water quality goals. It allows watershed and stormwater practitioners to develop, evaluate, and select optimal BMP/LID/GI combinations at various watershed scales based on cost and effectiveness. It extends the capabilities and functionality of InfoSWMM by providing integrated analysis of water quantity, quality, and cost factors. Definitions: o BMP: Best Management Practice o LID: Low Impact Development o GI: Green Infrastructure o SUDS: Sustainable Urban Drainage Systems o SUSTAIN*: System for Urban Stormwater Treatment and Analysis Integration *Developed by EPA's Office of Research and Development (ORD)
