Expand/Contract Questions and Answers
- The weeds growing in the planting strip are the responsibility of the property owner adjacent to the strip. Mulch and other similar deterrents can be added to fill in the tree grates. Using plant-killing chemicals around a tree is not advised since it is dangerous to the tree’s health.
- Yes, when the threshold of the infestation creates a health or safety issue for the tree or residents. City personnel will not spray every time a pest is observed. This would not be a responsible use of pesticides. Whenever possible, natural predators are used for insect control. If chemicals are required, we use the least toxic materials available. Redwood City applies an Integrated Pest Management (IPM) approach to pest control (see Redwood City’s Tree Pest Management Philosophy). The objective is to control pests while minimizing the use of chemicals.
- City personnel perform routine maintenance on the approximately 18,000 street trees and 15,000 park trees. Due to the magnitude of the inventory, the most critical and high priority work is scheduled first. We perform as much work as possible in the more efficient block pruning approach. A long-term maintenance schedule is not available at this time.
- During normal business hours please call 650-780-7464.
- If it is an emergency, threatening life or property, call 911. During normal working hours please call 650-780-7464 to report the address and circumstances. For non-emergency situations, go to the Report Problems web page and submit a report.
- City personnel are maintaining existing trees. Funds are budgeted to preserve this natural asset. However, with budgetary limitations, there is always more that can be done. We encourage property owners to help by watering their newly planted trees.
- City personnel only spray trees by request. When responding to requests for pest control, city personnel will evaluate the situation and determine if the threshold of the pest warrants spraying. If chemicals are warranted, the treatment will be scheduled and the resident will be advised about the pesticide being used, any cautions related to the treatment and the proposed schedule.
- See Aphid Control.
- City personnel are maintaining existing trees. New trees will supplement the existing canopy, enhancing the city’s beauty. However, the canopy develops over time, it will not occur overnight. We have modified the pruning strategies for new trees to avoid some of the structural issues we have experienced with our older trees.
Pruning
Expand/Contract Questions and Answers
- In most circumstances, No! Tree topping is generally discouraged throughout the arboricultural industry (see Best Management Practices). City policy encourages the growth of tall spreading shade trees. Our pruning methods comply with the International Society of Arboriculture best management practices and the ANSI A 300 Standards.
- The actual time to prune a tree may range from 30 minutes to 4 hours depending on the needs of the tree.
- City-owned trees are those trees growing within the public Right-of-Way. Most trees along Redwood City’s streets in the strip of land between the street and the sidewalk are city-owned. Where this strip doesn’t exist, city-owned trees may be planted behind the sidewalk. A representative from the City will visit your location and determine if the trees in question belong to the city.
- The Public Works Department maintains and prunes all city-owned trees based on available resources. If you wish to accelerate the pruning cycle, you may secure a permit and have the tree pruned to the City’s standards by a reputable arborist.
- City staff only maintains city-owned trees. It is the responsibility of the property owner to maintain trees on private property.
Planting
Expand/Contract Questions and Answers
- No, the property owner cannot choose what type of tree the city plants. Only tree types designated for a particular block will be planted.
- We will plant as many trees as space and proper tree care allow. Trees will not be planted under the following conditions:
- New tree would be closer than 15 feet from an existing tree.
- New tree would be closer than 8 feet from a fire hydrant.
- New tree would be closer than 4 feet from a water meter box or utility vault.
- New tree would be closer than 15 feet from a street light.
- New tree would be closer than 8 feet from a sewer line.
- New tree would be too close to an intersection. It would eventually create an across-the-intersection vision problem.
- Tree planting is performed when enough requests are received to justify an order from the nursery. Typically, large tree planting events are scheduled in the spring and fall.
- City planting policies require the planting of medium large tree species. Generally, each block will have the same species to maintain the character of the street. Only tree types designated for a particular block will be planted.
- City personnel determine which trees are for a particular street and where the tree will be planted. Considerations for the location include: spacing, sewer lines, proximity to concrete improvements, street lights, etc.
- Yes. City staff will plant a 15 gallon tree, free of charge.
Removal
Expand/Contract Questions and Answers
- The wood from city-owned trees belongs to the citizens of Redwood City. Usable wood is left along the public thoroughfare. Citizens may pick up the wood on a first come first serve bases after the crew has left the job site.
- In most cases, no. Generally, only trees found to be dead, dying, structurally unsound, causing structural damage to private property, obstructing a permitted improvement such that it will be killed or become structurally unsound when the improvement is implemented, or other compelling reason approved by the City are approved for removal. Certain construction permits may cause the removal of a tree. There will be a replanting condition based on the size of the tree removed.
- In most cases, messiness is not sufficient cause to remove a tree. Place tree trimmings in the green organics cart to be turned into compost.
- Please complete a tree permit application and submit it to the Public Works Department. Information about tree permits can be found on the Tree Maintenance web page.
- A tree is only removed that is dead, dying, structurally unsound, causing structural damage to private property, obstructing a permitted improvement such that it will be killed or become structurally unsound when the improvement is implemented, or other compelling reason approved by the City. Trees are inspected and the decision to remove is made on a case-by-case basis.
- The City has a Tree Preservation Ordinance protecting trees growing on private property that are greater than a minimum size. Please see Tree Maintenance for an overview.
Tree Preservation Ordinanace
Expand/Contract Questions and Answers
- City personnel will not recommend one tree company over another. It is recommended that you solicit more than one estimate prior to hiring a company and that you feel comfortable that the company you hire can perform the work to the ANSI A-300 Pruning Standards. All tree companies operating in Redwood City must have a current Redwood City business license. If the job is over $500, the state also requires the company to have a State Contractors License. Redwood City does not enforce the State requirement.
- You can do the work yourself. Tree maintenance can be very dangerous. Homeowners need to evaluate their skills and capabilities before endangering themselves. City staff will provide specifications for pruning and provide you a copy of the ANSI A-300 Pruning Standard and International Society of Arboriculture best management practices to guide you.
- Yes. All trees require a permit to prune or remove if they are larger than 38 inches in circumference. If branches or roots are overhanging your property line from a neighbor’s tree, you are not required to have a permit to trim encroaching branches or roots back to the property line. It is your right to remove overhanging branches or encroaching roots provided such pruning does not kill or severely compromise the tree. However, it is recommended to inform your neighbor of the pending work.
- Go to the Tree Maintenance web page.
- In most cases it takes 10 working days to process a permit. If there is an emergency situation, staff will respond as soon as time and resources allow, often the same day. When non-emergency applications are submitted as an emergency, they will not receive priority approval.
- There is no fee for a permit to prune or remove a tree at this time.
- Measure the tree trunk at its largest point between six and 36 inches above the ground.
- In 1970 the City Counsel passed the Tree Preservation ordinance to protect trees growing on private property. The ordinance requires a permit to prune or remove any tree larger than 38 inches in circumference measured between 6” and 36” above ground.
