For traffic control devices to be visible this will mean the landscaping will have to be maintained at a height greater than seven feet.
The land between the street and private property line is part of the public right-of-way. However, City Codes require the adjacent property owner or resident to maintain this area, including the adjacent sidewalk.
In nearly all cases the offending tree, shrub, fence, etc. is either on private property or was placed on the public right-of-way by the adjacent property owner or resident. It is, therefore, the property owner's or resident's responsibility to maintain the area so it does not cause problems. That is just being a good neighbor.
We try to notify the property owner or resident of the need to correct a problem and give them a reasonable time to make the necessary corrections.
