Tree Management Plan Summary
The residents and the City Council of Redwood City have made trees a priority
for the environmental and quality of life benefits they provide. Two ordinances
have been enacted to protect the presence and value of trees in the community.
- A Street Tree Ordinance protects all street trees growing on public property
adjacent to roadways throughout the city.
- A Tree Preservation Ordinance protects all trees growing on private property
with trunk sizes that exceed 38 inches in circumference (twelve inches in
diameter) measured between six inches and 36 inches above ground.
This management plan describes the tree objectives, management guidelines
and practices that are being implemented
to sustain the urban forest within Redwood City. City Council priorities created
the vision (how the urban forest should look), and Urban Forestry Practices
provided the guidelines for achieving the vision. This plan is a living document,
it will evolve over time as new tree species are developed and industry standards
and practices advance.
- To maintain a safe urban forest.
- To have a fully stocked urban forest consisting of an acceptable blend
of species diversity, mixed-age, and large shade tree varieties.
- To budget effectively to maintain these resources and to follow a planned
- To maintain the Tree City USA designation which requires:
- A minimum budget.
- An Arbor Day celebration.
- A tree ordinance.
- A citizen tree-oversight body.
- To perform maintenance activities to accepted arboricultural industry standards
- American National Standards Institute A-300 Pruning Standards
- International Society of Arboriculture Best Management Practices.
- UC Davis planting and staking standards published by Dr. Richard
- To communicate with the residents and businesses in Redwood City about
tree maintenance activities in a timely and professional manner.
- To practice an Integrated Pest Management (IPM) approach to insect and
disease control. IPM uses predatory insects and non-chemical controls first
and low toxicity chemicals only when necessary.
Tree Management Guidelines
The following guidelines are based on Urban Forestry scientific principles.
- Provide adequate space for a tree to develop – both above and below
- Provide the proper environment – protect from damage, provide appropriate
soil conditions, select the proper tree for the climate.
- Maintain a planned level of shade coverage for a street. Balance mixed-age
trees, ranging from about one-third mature shade trees, with one-third middle-aged
trees, and one-third young trees.
- Apply professional standards for tree care and management.
