Tree City USA

The City of Napa is recognized by the National Arbor Day Foundation as a Tree City USA, learn more on the National Arbor Day Foundation website. The City strives to maintain this honor through tree preservation, care and reforestation programs such as Arbor Day. There are a number of City ordinances that protect both public and private trees. These regulations are included in Street Tree, Protected Native Tree, and Significant Tree Programs. The Tree Advisory Commission works with City staff and advises the Council on all issues involving trees, both public and private, throughout the community. The Commission may also serve as an appeals board on tree related matters.

Street Tree Program

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 City is responsible for the maintenance, removal, and planting of street trees as well as pruning the trees for street and sidewalk clearance, and 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. Applications and appropriate fees will need to be submitted in person at the Parks and Recreation Services office. Learn more on the Tree Advisory Commission page.

Master Tree List

The City values the right tree for the right place when it comes to new plantings. The City of Napa maintains a Master Street Tree List that consists of trees that can be planted within the City right-of-way. The location of utilities, soil type, and available planting areas are all part of this criteria.

Arbor Day

Arbor Day has been celebrated in the City of Napa since 1990. The City is recognized by the National Arbor Day Foundation as a Tree City USA for its commitment to urban forestry. Each year City staff and the Tree Advisory Commission plant trees with help from the community in a public place, such as parks and schools. It is estimated that over 800 trees have been planted as part of this annual celebration since 1990.

Protected Native Tree Program

The removal or pruning of a protected native tree is prohibited unless a permit is first applied for by the property owner or person authorized by the property owner. Applications will be reviewed by City staff to determine whether it is part of a discretionary development application or if the application will need to be brought before the Tree Advisory Commission for a final determination.

Protected native trees are specific species of trees located on private property one acre in size or larger, zoned for residential or agricultural purposes, or located on property zoned for commercial or industrial purposes. In establishing this protection of specified trees, it is the City’s intent to promote a healthy urban forest that contributes to clean air, soil conservation, energy conservation, scenic beauty, enhanced property values, and quality of life; ensuring that Napa will continue to be a desirable place to live and work. Section 12.45 of the municipal code regulates Protective Native Trees.
