Designed for Duluth, Lakewood, and Rice Lake Townships (in the Duluth Metropolitan Area)- Minnesota Greenview is an online mapping tool that provides a user-friendly front end to information needed by homeowners interested in remodeling, new construction, or simply reducing stormwater runoff from their properties. The application provides parcel-level information on the amount of impervious surface (e.g. driveways, patios, rooftops), forest cover, wetland and green space, along with soil and topographic information. By summarizing data at the parcel level, homeowners can determine how future construction will affect runoff, and how structures such as green roofs or rain gardens can be used to reduce stormwater runoff. Tailored to townships on Lake Superior's north shore, GreenView provides inputs to stormwater management programs developed by federal and state agencies. At the broad scale, it creates a file that can be read by the EPA's National Stormwater Calculator (NSC). The NSC is a generalized application that estimates the annual amounts of rainwater and runoff anywhere in the United States, and demonstrates how low impact development techniques, from rain barrels to green roofs, can reduce that runoff. It also provides data for the MN Pollution Control Agency's more specific Minimum Impact Design Standards (MIDS) calculator, which allows evaluation of networks of LID and water retention features. |

EPA’s National Stormwater Calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States (including Puerto Rico). The user supplies information about the site’s land cover and selects the types of low impact development (LID) controls they would like to use. Intended users? Anyone interested in reducing runoff from a property, including site developers, landscape architects, urban planners, and homeowners. |

The MIDS calculator is a tool designed to quantify reductions in post-development runoff and pollutant loading using a variety of Low Impact Development practices. This graphic user interactive tool allows individuals to enter a project's site contitions and determine the amount of stormwater volume retention needed and the pollution loading (sediment and phosphorus). The calculator then provides a method to enter the users stormwater practices of choice and calculate the amount of stormwater volume and pollution reduction they can achieve. Intended Users? Minimal Impact Design Standards Calculator was developed for designers, engineers, planners, contractors, stormwater managers, landscape architects |

During storms, much water runoff enters the storm system from developed areas. The runoff picks up pollutants originating from motor vehicles and lawns and often carries them to streams and lakes. To address this concern, the EPA enacted new regulations in October 1999, known as the EPA Phase II Storm Water Rule. | ||||

What is I&I? I&I stands for Inflow and Infiltration. I&I is the process by which clear water enters the sanitary sewer system. |

In a long-term effort to promote positive community and individual activities to protect the waters of the region, 16 governments and groups combined in 2003 to form the Regional Stormwater Protection Team (RSPT). | ||||

This “toolkit” includes information associated with a new, comprehensive land planning and engineering design approach that aims to minimize stormwater impacts associated with water quality, hydrology (volume of water and peak flows), water supply, flooding and physical effects. | ||||
