Revision as of 20:34, 19 January 2022

This page contains information on webinars for the Minnesota Stormwater Manual. Please note that the PowerPoint files may contain links. To make the links live you must be running the Powerpoint slide show.

January 19, 2022 - Pretreatment

Overview: While the benefits of pretreatment are well understood, we continue to see ineffective pretreatment as a result of poor design or construction, inadequate maintenance, incorrect choice of practice, inadequate sizing, and so forth. The objectives for this webinar are to reiterate the role and importance of pretreatment, provide examples of good and recommended practices, and discuss some common concerns with pretreatment implementation.


  • Introduction to and importance of pretreatment: Dr. John Chapman, Department of Bioproducts and Biosystems Engineering, University of Minnesota
  • Examples of selection, implementation and efficient maintenance of pretreatment practices
    • Noah Czech, Stormwater Compliance Specialist, City of St. Cloud, Minnesota
    • Mike Isensee, CPESC, Administrator, Carnelian Marine St. Croix Watershed District
  • Observation of pretreatment practices - the good, bad, and ugly
    • Chris French, Regulatory Manager, Bio Clean Environmental

May 26, 2021 - Engineered media

Overview: Engineered media and designs with media amendments are increasingly being used to meet water quality targets for stormwater runoff. This webinar will highlight on-going work related to bioretention and engineered media.


  • U of M research on engineered media: Andy Erickson
  • On-going research
    • Biochar: Ed Matthiesen (Wenck Environmental Consulting and Engineering, now a part of Stantec)
    • Spent lime in permeable barriers: Keith Pilgrim (Barr Engineering)
    • Layered systems: Curt Coudron (Dakota County)
    • Compost: Andy Erickson (University of Minnesota)
    • Peat, taconite: Meijun Cai (University of Minnesota Duluth)

May 13, 2021 - Street Sweeping

Overview: This webinar will provide information on the importance and value of street sweeping for controlling nutrient loading to receiving waters, an overview of a new street sweeping crediting tool for phosphorus, a discussion of street sweeping guidance, and a discussion of additional research needs. The tentative agenda is as follows.


  • Opening statement - the importance and value of street sweeping: Randy Neprash, PE, Minnesota Cities Stormwater Coalition, Stantec
  • Discussion of trees as a source of nutrients in urban stormwater, focused on impacts of trees: Dr. Sarah Hobbie, Distinguished McKnight University *Professor, Dept. of Ecology, Evolution & Behavior, University of Minnesota
  • Overview of recently developed street sweeping calculator: Aileen Molloy, Tetra Tech
  • Overview of draft guidance for street sweeping: Hillary Yonce, Tetra Tech
  • Discussion of additional research needs: William Selbig, Research Hydrologist, USGS Upper Midwest Water Science Center

June 18, 2019 - Minnesota Stormwater Manual updates on Stormwater Pretreatment Practices

Overview: This webinar covered material developed through multiple work orders during 2018-2018. The objective was to update the pretreatment information in the Minnesota Stormwater Manual, which included information on vegetated filter strips, settling practices, case studies, and a tool for selecting the appropriate pretreatment practice.


  • Forrest Kelley (Capitol Region Watershed District) - local perspective on pretreatment
  • Katy Thompson (RESPEC) - case studies
  • Dr. Scott Struck (Geosyntec) - pretreatment practices and pretreatment selection tool
  • Dr. John Gulliver - pretreatment sizing
  • Dr. Andy Erickson - pretreatment filter strips

February 27, 2019 - Infiltration at sites with potential contamination

The MPCA hosted a live webinar on February 27, 2019, 8:30-11:30. The presenter was Mike Trojan from the MPCA and the webinar was attended in person by several stormwater representatives.

August 7, 2018 - Stormwater management for Solar Projects

The Minnesota Pollution Control Agency (MPCA) hosted a live webinar on Tuesday, August 7, 10:00-11:00 (Central time). Abstract:


  • Logan Quiggle - Stormwater Engineer; MPCA


January 9, 2018 - Maximizing stormwater BMPs for phosphorus removal

The Minnesota Pollution Control Agency (MPCA) hosted a live webinar on Tuesday, January 9, 1:30-3:30 (Central time).

Abstract: Despite our best intentions, sometimes our stormwater Best Management Practices do not do what we want or expect of them. This is particularly true for stormwater management of phosphorus. We have invited three expert speakers to discuss three particularly important and perhaps not fully understood BMPs – wet ponds, bioretention, and street sweeping/litter management. The speakers will discuss why these BMPs have often not achieved water quality goals for phosphorus and present approaches to maximizing their pollutant removal effectiveness.


  • Joe Bischoff - Principal Aquatic Ecologist; Wenck Associates, Inc.
  • Dr. Andy Erickson - Research Associate; St. Anthony Falls Laboratory; University of Minnesota
  • Dr. Sarah Hobbie – Professor; Ecology, Evolution, and Behavior; University of Minnesota


May 30, 2017 - Bioretention From the Ground Up

The MPCA hosted a live webinar on updates to the MIDS Calculator (Version 3). This webinar focused on bioretention media, bioretention vegetation, and tree-based bioretention. Guest speakers included:

  • Fred Rozumalski, Registered Landscape Architect- Barr Engineering
  • Marcy Bean, Professional Landscape Architect-Mississippi Watershed Management Organization and
  • Mike Isensee-Administrator, Middle St. Croix Watershed Management Organization


March 15, 2017 - Updates to the Minimal Impact Design Standards (MIDS) Calculator

The MPCA hosted a live webinar on updates to the MIDS Calculator (Version 3). This webinar focused on recent updates to the MIDS Calculator and included example applications and a tour of the supporting information in the Minnesota Stormwater Manual. The webinar included the following topics:

  • Using the new underground infiltration BMP
  • Using the updated harvest and use BMP
  • Using the new impervious surface disconnection BMP
  • Several other minor changes will be briefly discussed (see Updates to the MIDS Calculator)


January 25, 2017 - Stormwater Harvest and Use/Reuse

December 15, 2016 - Infiltration Practices

Professional development hours

Attendance at a Stormwater Manual webinar, MIDS Calculator training, or Simple Estimator training qualifies for Professional Development Hours (PDH) for the Minnesota Board of AELSLAGID. Look for links to certificates with each qualifying webinar (above). The event may qualify for other professional development credit, but be aware that we have not verified that with other licensing organizations.

Note that it is your responsibility to attend the webinar and document your attendance, including downloading the certificate. The MPCA documents people who attended the webinar or training, including the times they were logged in to the event, and will provide this information to certifying boards if requested. We cannot document people who have viewed recorded webinars. We provide a form summarizing the justification for offering pdhs.
