Important Notice

Until we can end physical distancing due to COVID-19 all of our classes are being conducted as live, interactive webinars.  Using GoToWebinar, we can create virtual classrooms with instructor-led training, and we can include input, questions, and feedback from each attendee.  If the device you connect with does not have a microphone and speaker, you can use a dial-in phone number to speak directly with us.  We have been conducting webinar-based training since 2010, and it seems that all of us will need to use this as platform well into the future.  We encourage you to give it a try - we think you'll enjoy the experience!

Here's some recent feedback on our webinars:

"The class reaffirmed most of what I am doing and filled in the gaps to everything I wasn’t sure about."

"I was concerned about this being in webinar format, but I think Jeff did a good job of asking for participation from all of us. It definitely made me stay focused on the content – even though I just wanted to be outside enjoying the nice weather on Tuesday!"

"Very interesting material. I wish there was a way to implement it without impeding upon the profit incentive of all the business people of the world.  I guess as the population on the earth increases, even doubling in the next 30 or so years, the need for clean water will become even more of a public incentive and it may become easier to get regulations in place that can help."

Training and Events

We offer a variety of courses on location, via webinar, and now as self-paced video learning from our website, all of which are instructor-led. Our instructors are former stormwater officials from the Federal or State level. Certification is valid for 5 years; graduates may take CSI – Recertification to extend their validation for an additional 5 years.

Permits require "Qualified Personnel" who conduct inspections be part of the Stormwater Team.  The National Stormwater Center certifies graduates.  This certification indicates that the services our graduates conduct are being performed by professionals who have met the established standards of knowledge, experience, and competence required in the field of stormwater inspections.  The National Stormwater Center's CSI-MS4 class has been an integral part of the success of 10,200 municipal inspectors across the country.
