Validate that the modeling method recommendation accurately results in the minimum BMP cost for 45 facilities of widely varying climatic and regional conditions.The demonstration will take place in two phases: The toolbox identifies the most cost-effective modeling method based on a facilityвЂ™s local conditions, provides a range of modeling platform sophistication, and facilitates ease of implementation. This project will demonstrate a Stormwater Management Optimization Toolbox that is specifically designed to help DoD facilities achieve compliance with regulatory stormwater requirements for the minimum cost possible. The demonstration took place in two phases: (1) demonstrate that the Model Selection Tool (MST) recommendation accurately results in the minimum BMP cost for 45 facilities of widely varying climatic and regional conditions, and (2) demonstrate SMOT at two facilities to showcase the capabilities of the model platforms, illustrate the ease of implementation, and ultimately validate the model selection element. This project demonstrated a Stormwater Management Optimization Toolbox (SMOT) that was specifically designed to help DoD facilities achieve compliance with regulatory stormwater requirements for the minimum cost possible. As a result, many DoD facilities over-build or over-size these BMPs to ensure compliance. These requirements can be complicated, contradictory, and difficult to plan for. This oftentimes requires facilities to plan, design, and implement structural best management practices (BMPs) to capture, filter, and/or infiltrate runoff. As stormwater regulations become increasingly stringent for hydrologic and water quality control, Department of Defense (DoD) facilities are faced with the daunting task of simultaneously complying with multiple laws and regulations, such as the Energy Independence and Security Act (EISA) of 2007, Clean Water Act Total Maximum Daily Loads (TMDLs), and Municipal Separate Storm Sewer Systems (MS4) permits.
