The water quality benefits of trees have been documented, but we are still working on quantifying the runoff and pollutant-reducing impacts of trees as a stormwater best management practice (BMP). Part of this uncertainty is how to “credit” urban trees for runoff and pollutant load reduction. This webcast will review ways to model these effects of urban trees and provide examples of their integration into state and local compliance systems for stormwater management, TMDLs and other water quality requirements. The webcast will highlight application of the Center for Watershed Protection’s stormwater performance-based credit to quantify the impact of urban trees on reducing combined sewer overflows in the City of Buffalo, NY, and the Green Infrastructure Center’s modeling of trees’ ability to reduce runoff in Charleston, SC.
