Welcome to the Minnesota Stormwater Manual website. The Manual is designed to be user-friendly and flexible to guide users directly to the information they need, depending upon the question they need to answer or Best Management Practice (BMP) they need to design. This website was developed in an interactive wiki format to make it easy for the user to get to the subject of interest and to move between subjects.

Acknowledgements

This Manual was initiated by the Minnesota Stormwater Design Team, which evolved into the Minnesota Stormwater Steering Committee (SSC). Manual production was directed by the SSC’s Manual Sub-Committee (MSC). A listing of contributors and participants in the process appears in the Acknowledgements section.

Overview

Throughout the production of the Manual, one singular goal was kept in mind – to produce a useful product that helps the everyday user better manage stormwater. The purpose, goal, vision and tenets were developed by the original Stormwater Design Team. Although stormwater management to control the pollution of receiving waters has been around in earnest for over 30 years in Minnesota, the advent of many new programs means that guidance is needed more than ever. Such programs as the NPDES (National Pollutant Discharge Elimination System) Phase I and II program, the TMDL (Total Maximum Daily Load) program, and strong runoff control programs at the local and watershed levels have all contributed to the need for this information to be compiled in a comprehensive, technically sound document.

The directive the Manual Sub-Committee received from the SSC was to produce a document that could be used as a single source to guide stormwater managers through the maze of regulations, Best Management Practices (BMPs) designs, models/techniques and terminology that constitute good stormwater management. It does not address the requirements of other non-stormwater related regulatory programs that can have an effect on stormwater. Related to this was the charge to produce a Manual that does not duplicate the many good sources of information already available. Because Minnesota is fortunate enough to have had many additional tools created over the years, the Manual will often forego detailed explanation of a particular element and send the user directly to another resource via electronic linkage or cited reference. These linked resources provide information that Minnesota stormwater managers can put to use in conjunction with this Minnesota Stormwater Manual. The Manual is intended to be flexible, easily updated and responsive to the needs of the Minnesota stormwater community.
