Frequently Asked Questions

Street trees are planted in two locations along city streets. Some are planted in the “landscape strip,” the open space that runs between the curb and the sidewalk. Where a landscape strip doesn’t exist, street trees are planted behind the sidewalk and are located in the front yard of the property owner. If you are unsure if a tree is a street tree, contact Public Works at (209) 895-8060 or by email at publicworks@ci.patterson.ca.us. A crew member will be happy to verify your city tree.

The Urban Forestry Division trims, plants and removes dying, damaged or diseased street trees. Property owners are not permitted to trim street trees. Please contact the Public Works Department at (209) 895-8060, or by email at publicworks@ci.patterson.ca.us for service requests.

Please contact the Public Works Department at (209) 895-8060, by email at publicworks@ci.patterson.ca.us or through our online reporting system at link . Staff will be happy to provide information on your street tree or make a site visit to evaluate the tree.

Approximately 17,000 street and park trees are trimmed on a 5 – 7 year cycle. Trees ranking as critical or high priority are scheduled for service first. Trees may be trimmed more frequently depending on the species and growth rate of the tree. Contact the Public Works Department for more information. Exceptions are made for safety hazards.

Call the Public Works Department to request a tree. Staff will evaluate your property to see if there is appropriate planting space. Considerations for planting include spacing, proximity to sewer, gas and water service lines, as well as proximity to sidewalks, driveways, streetlights, etc. City tree planting is typically scheduled in the fall and spring.

The city has a master tree list that has been approved by the City Council. Only trees approved for that street will be planted if replacement is necessary. This master street tree list has tree species selected for each street in Patterson.

The property owner is responsible for watering young city trees. The first two years are critical and the tree will need to be watered weekly from spring through fall.

The property owner is responsible for damage caused by tree roots and for mitigating root issues on private property. The city may repair damage caused by roots to public improvements such as sidewalk, curb and gutter.

Normally, a city tree is removed only if it is dead, dying, structurally unsound, or creating a problem that cannot be resolved without causing great harm to the tree. City tree removal requests are processed on a case-by-case basis which includes a site inspection. The decision is made by the City Arborist.

In most cases, no. Typically, only trees that are dead, dying or structurally unsound will be removed. Contact Public Works at (209) 895-8060 or by email at publicworks@ci.patterson.ca.us if you would like your tree evaluated.

Generally, no. All trees provide a benefit to the community but there can be a cost associated with the benefit. The cost may be leaf litter, fruit or pod droppings or root issues. In most cases, these are not sufficient reasons to remove a street tree. The city provides a leaf pickup program during the fall.

The Urban Forestry Division crews treat specific trees by request. When there is a request for pest control, division staff will evaluate each situation to determine if treatment is required. If action is recommended, treatment will be scheduled and the resident will be advised.

The city will perform safety trimming if crews are in the area performing regular maintenance on city approved trees.
