Our current street tree maintenance system is bad for many reasons. It jeopardizes the health of our urban forest, puts residents in danger of falling limbs, and dumps responsibility for trees onto property owners who didn't plant the trees and might not be able to take of them. We need a long-term solution to this issue that includes a dedicated funding source for tree maintenance so that the money isn't raided for other purposes.
I have announced plans to draft legislation and form a working group to determine the best way to create an Urban Forest Fund and how to fund it. San Francisco Weekly has published a story on this issue in their current issue, which you can read here.
