Street Tree Program 

red maple tree.jpg
A street tree is any tree located within the public right-of-way, generally located between the sidewalk and street, within ten feet of the curb, or even in some areas where curbs and sidewalks do not exist.  Street trees are protected by ordinance and are considered public property by the City of Napa. The Parks and Recreation Services Department can provide residents with information on a particular right-of-way location to determine if you have a Street Tree. The overall responsibility for the maintenance, removal, and planting of street trees is the responsibility of the City. The City prunes the trees for street and sidewalk clearance, and for the removal of dead, weak or hazardous limbs. While pruning conforms to accepted professional standards, street trees are not pruned for aesthetic purposes. Pruning may be done by the adjacent property owner with a permit from the Parks and Recreation Services Department. Pruning must adhere to City standards in order to protect the health and vitality of public trees.
