The pruning program would target those trees in the public right-of-way that are most in need of pruning (Priority 1). The initiative is also focused on the larger of the city’s street trees – those bigger than 20 inches in diameter. Those are the trees that have the greatest impact on the mitigation of stormwater.
According to the staff memo accompanying the resolution, the city of Ann Arbor has over 46,600 street trees, counting street trees and those in parks. According to the staff memo: “Those trees intercept over 65 million gallons of stormwater annually and remove pollutants, such as fertilizer, oils, and pesticides, before they can enter local water bodies (USDA Forest Service i-Tree Streets Analysis of Ann Arbor, 2009).
