If you notice a street tree that has been damaged or knocked over by a vehicle, or vandalized, or that has dropped a limb or fallen over, or looks like it might fall over, please report it!
Friends of the Urban Forest can provide emergency care for small young trees (for about the first five years after planting). But FUF is not equipped to care for mature trees. Thanks to voter approval of the Healthy Trees and Safe Sidewalks initiative (Proposition E) in 2016, the City of San Francisco has funding to maintain all mature street trees in the City (and to repair tree-related sidewalk damage).
Report problems with mature street trees to SF311, the city’s “customer service” department, by calling 311 from any 415 area code phone, or via their website, or via the SF311 mobile app. If you submit a report via their website or app, it’s helpful to also submit photos that show the problem.
