![]() ![]() Calculates the stormwater runoff volume reduction performance goal for a site.Below is a detailed discussion of the main objectives of the MIDS calculator and the calculations that take place to meet those objectives. A detailed overview of individual input parameters and workflows is presented in the MIDS Calculator User Documentation. Results include pollutant removal rates and loads, annual volume reduction, as well as conformance to the MIDS performance goal. Finally, in the “Results” tab, results are displayed for the entire site as well as individual BMPs. In the “BMP Properties” window the user enters land use areas, routing information, and design parameters specific to an individual BMP. The “Schematic” tab is where the user adds or removes BMPs to the site and provides a visual diagram of all BMPs and routing between BMPs. This includes information used to calculate annual precipitation for the study area, average pollutant concentrations in runoff from the entire site, as well as land used areas for the entire study area. The “Site information” tab is where the user enters information for the entire site being studied. The MIDS calculator is divided into four main components: the “Site information” tab, “Schematic” tab, “BMP Properties” window, and “Results” tab. The Excel spreadsheet conducts the calculations and stores parameters, while the GUI provides a platform that allows the user to enter data and presents results in a user-friendly manner. The MIDS calculator is designed in Microsoft Excel with a graphical user interface (GUI), packaged as a windows application, used to organize input parameters. The MIDS calculator estimates the stormwater runoff volume reductions for various BMPs based on the MIDS performance goal (1.1 inches of runoff off impervious surfaces) and annual pollutant load reductions for total phosphorus (including a breakdown between particulate and dissolved phosphorus) and total suspended solids (TSS). Note that Version 3 files cannot be used in Version 4 but you can have Versions 3 and 4 loaded on your computer at the same time.Ī Minimal Impact Design Standards (MIDS) best management practice (BMP) calculator was developed to assist designers and regulators in determining conformance to the MIDS performance goals The MIDS BMP calculator is a tool used to determine stormwater runoff volume and pollutant reduction capabilities of various low impact development (LID) BMPs.
