With a revised MS4 permit in 2017, revised construction, commercial, and industrial stormwater permits,  and a new Stormwater Quality Manual going into effect in March, there has been a move to use lower impact approaches to stormwater management. This webinar will cover takeaways, challenges, and opportunities from this approach. What is working, what is a work in progress, and what is coming?
