In this webinar, attendees will explore cost-effective solutions to minimize or eliminate storm water discharge exceedances, as well as the risk of violations and fines. Larsen will discuss how a series of small, cost-effective best management practices (BMPs) such as sediment traps, bioretention media, vegetated percolation, and infiltration trenches close to the source can minimize or eliminate regulatory discharges. 

Three main categories of techniques are presented--infiltration, filtration and detention--as well as case studies, their violations and the preventative solutions in hindsight. Larsen will present several projects where plan review and simple measures prevented storm water discharges through containment or infiltration, saved thousands of dollars and eliminated risk. 

As a leader, creating a clear, compelling vision of storm water compliance success is essential. Storm water management and containment practices largely have been in response to growing community awareness of the environmental effects of urbanization on water quality. Larsen will articulate how goals and responsibilities can be informed by an interest in educating and creatively leading by example to minimize and eliminate pollutant sources in our storm water discharges.
