They may have some special circumstances. If the situation doesn't improve, call the Health and Safety Department at 221-6615. An inspector will come out and investigate within 24 hours, and if a problem is found, will give a 7 day warning to the owner. If after 7 days, no action has been taken by the owner, the City could choose to issue a ticket or have the property mowed and bill the owner. Although beautiful, trees and shrubs can be hazards for motorists, cyclists, and pedestrians.
Corners can be a particular problem.
Shrubs and trees must be trimmed so that you can easily see around the corner when approaching it. If a tree hangs out over the street, the bottom branches must be at least 14 feet high for vehicle clearance. All shrubs and low growing vegetation must be kept back from the edge of the sidewalk so it is completely open. If so, talk with your neighbor about how to handle this. You do have the right to trim their tree back to the edge of your property line as long as you do not damage the health or aesthetics of the tree.
