Tree Removal

Don’t go out on a limb – know the laws about tree removal.

“City in a park” is not just a marketing slogan for Bellevue, with abundant trees on public and private property helping make the city beautiful and healthful.

The city’s trees aren’t just pretty; they absorb stormwater runoff and carbon dioxide and other pollutants while producing oxygen. Preserving Bellevue’s tree canopy was identified as a priority when the City Council launched an environmental stewardship initiative in 2007.

A variety of rules protect trees in Bellevue. Under certain conditions, residents must obtain a permit to cut or prune trees on their property. It is illegal to remove, prune, or “top” trees on public property; and the penalties are stiff.

The city receives many questions about tree regulations. Here are answers to some of the most frequent ones regarding tree removal:

FAQs for Tree Removal on Private Property

Do I need a permit to remove one or more trees from my property?

In most cases, the answer is No. A permit, however, is required if one or more of the following conditions are true:

  • Tree removal results in removal or destruction of more than 1,000 square feet of existing soil cover, which includes tree canopy.
  • The property is part of a designated critical area or buffer.
  • The tree removal includes more than five (5) significant trees.
  • The tree is in a native growth protection area or a retained vegetation area.
  • The tree is on the city’s right of way.
  • The property is located in Bridle Trails.

What is existing soil cover?

It is the vegetative or non-vegetative material that is covering the soil before the tree removal project, and which provides a barrier against erosion.  

  • Vegetative soil cover includes vegetation such as grass, weeds, groundcover, brush, shrubs, and tree canopy.
  • Non-vegetative soil cover includes material such as rocks, mulch (wood, bark, rock, stone, etc.), wood, asphalt or cement concrete, metal, plastic, and lumber.

How do I estimate how much existing soil cover will be removed or destroyed as a result of tree removal?

The bulk of soil cover that is lost due to tree removal is generally from the canopy of the trees that are removed. The tree canopy is the layer of leaves, branches, and stems that cover the ground when view from above.  

The area of tree canopy can be estimated based on measurements at the ground level from directly below the tips of the outermost branches.  A recent aerial photo can also be used to estimate canopy area.

Any other areas of soil cover loss during tree removal, such as removal of grass, landscaping, structures, etc. must be counted as part of the total removal of soil cover.

What are “critical” areas?

The city of Bellevue regulates six types of critical areas in its Land Use Code:

  • Streams and riparian areas
  • Wetlands
  • Habitats for species of local importance
  • Geological hazard areas
  • Flood hazard areas
  • Shorelines

These areas are given special protection because they provide unique environmental functions that are difficult, if not impossible, to replace and because they ensure public health, safety, and welfare.

Who can I contact to obtain a permit?

Visit Permit Processing in Development Services or contact them at 425-452-4898 or permits@bellevuewa.gov.

What if I am concerned about the health or safety of my trees?

One of the leading reasons given for tree removals is safety. To ensure you are not needlessly removing an otherwise healthy tree, it pays to talk with a qualified certified arborist or certified forester. There are two websites that can help. Contact the International Society of Arboriculture at www.treesaregood.org or the Society of American Foresters at www.safnet.org.

What if I have a dispute with my neighbor about a tree?

Tree “ownership” is determined by whose property the trunk stands completely on. If the tree is a boundary tree (the trunk straddles a property line), it is owned jointly. In most cases, property owners may trim branches and roots which encroach on their property if they stay within certain guidelines: trim only up to the property line; do not enter the owner’s property without permission; do not destroy or damage the tree by trimming roots or branches.

If you have a dispute with your neighbor, call the Mediation Program at 425-452-4019. They can help you explore your alternatives, coach you on how to negotiate with your neighbor, or provide free mediation to help you and your neighbor find a workable solution.

FAQs for Tree Removal on Public Property

May I remove trees adjacent to my property, either in a public right of way or a park?

No. The public is not authorized to remove (or reduce) any vegetation-including trees-from any public property. Please refer to your property title report, or e-mail either rightofwayuse@bellevuewa.gov or parksweb@bellevuewa.gov to help determine whether a tree is on public or private property.

I noticed that some public trees look unhealthy. What can I do?

The city has foresters and arborists on staff to respond to your concerns. To report a potentially unhealthy tree on park property, call 425-452-6855 or email parksweb@bellevuewa.gov . To report a potentially unhealthy tree in the public right of way, call 425-452-7840.

What happens if I remove, top, or otherwise prune a tree on city property without permission?

You may face civil penalties, including fines up to three times the assessed value of the trees involved. Depending on the circumstances, criminal charges may also be brought.
