In 2009, a TMDL for Moon Brook – an impaired stream in Rutland, Vermont – was established to reduce the impacts from stormwater runoff. The city wanted to leverage its robust urban forest program and canopy to help meet its reduction goals. Viewed as the most cost-efficient solution, they conducted an analysis of the existing canopy as well as areas where canopy could be expanded with maximum impact on the Moon Brook watershed.
They found that the city was maintaining 37% urban canopy, with another 51% of city area that could support trees. This data was integrated into a parcel-scale GIS layer of the city’s decision support system. With this type of high resolution mapping, the town was able to target where conservation and expansion of canopy would be most effective, considering zoning requirements and planting efforts within the watershed.
