Recommendations of the Expert Panel to Define Removal Rates for Urban Filter Strips and Stream Buffer Upgrade Practices

This expert panel report (2014) establishes pollutant removal crediting methods for urban filter strips, recommending runoff reduction and treatment-based load reduction rates derived from a synthesis of literature and stormwater design guidance across the Chesapeake Bay watershed. It concludes that urban filter strips can be credited when specific qualifying conditions are met and verified post-construction, while finding insufficient evidence to support crediting stream buffer upgrades as a distinct urban BMP.
