Tree Trimming

The street tree in front of 25 Clark St is dead and appears to have been that way for several seasons. I'd like to request it be removed. The tree is on a fairly heavily used street, as people often park and walk on it to access the restaurants on State Street. In addition to being an eyesore, I'm concerned that the tree may pose a hazard as any falling branches are likely to land on parked cars. Some lower branches have already broken off. The dead tree is ~25 feet tall, and was a maple. Thank you!
