EPA Phase II Stormwater Rulue

Designed for Duluth, Lakewood, and Rice Lake Townships (in the Duluth Metropolitan Area)- Minnesota

Greenview is a mapping tool that provides a user friendly front-end to information needed for stormwater management. This tool allows you to zoom in and out on your property, measure distance and area, and view different layers of data including topography, soils, watersheds, zoning, aerial photographs. It is also designed to provide inputs to stormwater management programs developed by federal and state agencies...see National Stormwater Calculator and MIDS Calculator below.

Launch Greenview Mapping Tool


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.

EPA Phase II Stormwater Rulue

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

EPA Phase II Stormwater Rulue
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.

I&I
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.

RSPT
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).

site design toolkit
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.

From June 17th through June 20th 2012, record rainfall caused the biggest flooding event ever recorded in the City of Duluth and surrounding communities. Learn more about the "Solstice Flood", including photo and video tours, agency reports, and other flood-related links.
