When tree work is happening on private property, the process can be fairly straightforward. But when a tree is near a roadway, requires equipment in the street, or affects the flow of cars and pedestrians, the project may require more than just the tree work itself. In Seattle, work that affects a public street can involve permits, traffic-control planning, review by the appropriate city agency, and a final traffic-control implementation plan before the tree work can safely happen.

That is why we do not always know the final traffic-control cost at the moment a tree estimate is first prepared. The work itself is one part of the project. The permit process, traffic-control plan, and actual street management on the work day are separate pieces that may require their own review and pricing.

At Washington Tree Services, we handle this process for our customers. We help coordinate the steps, review the site conditions, prepare the needed documentation, and make sure the project is set up properly before the work begins.

Step 1: Determine whether traffic control is required

Not every tree project needs traffic control. Some jobs can be completed entirely on private property with no public street impact. But other projects may require temporary restriction, management, or closure of a portion of a public street.

This can happen when:

• A tree is close to the roadway
• Limbs or sections of the tree need to be lowered toward or across the street
• Equipment needs to operate from the roadway
• A crane, bucket truck, chip truck, or other equipment affects the travel lane
• Workers need a protected work area
• Pedestrians or vehicles need to be redirected
• A lane or roadway may need to be temporarily closed

The exact traffic-control requirements depend on the location, the road configuration, the amount of traffic in the area, the work being performed, and the requirements imposed by the permitting authority. A quiet residential street may need a simpler traffic-control setup than a project along a busy arterial or a more complicated intersection.

Step 2: The $250 permit submission fee

Once we determine that a project may involve public-roadway impacts, Washington Tree Services begins the permitting process with a $250 permit submission fee.

This fee is separate from several other project costs, and it is important to understand the difference.

It does not equal the government permit charge. It does not include the cost of preparing the traffic-control plan. It does not include the cost of actual traffic-control implementation on the day of the job. And it does not include the tree work itself.

The $250 fee covers Washington Tree Services' permit-submission and administrative process. It is the cost associated with beginning the process and gathering the information needed for review. The final costs for the city or agency, the traffic-control plan, and the on-site traffic control are separate.

Step 3: Traffic mitigation and traffic-control plan

In many public-street projects, a traffic-control plan or traffic mitigation plan must be prepared. This document shows how vehicles, pedestrians, workers, equipment, lanes, signs, cones, flaggers, and the work zone will be managed during the project.

This is a very important part of the process. It is not just a generic form. The plan may need to show how the work area is protected, how traffic moves around the work zone, and what equipment or people will be used to keep the street safe.

At Washington Tree Services, our pricing for preparing the plan is:

• 1 page: $300
• 2 pages: $600
• 3 pages: $900
• 4 pages: $1,200

The pricing is $300 per plan page. The required number of pages is not chosen arbitrarily. It depends on the complexity of the project and the requirements imposed during review.

Step 4: Government permit fees

Any applicable Seattle DOT or city permit charges are separate from Washington Tree Services' $250 submission fee and the cost of preparing the traffic-control plan.

Those government fees are passed through or charged as applicable. We do not publish a specific Seattle permit fee unless the current amount has been independently verified. Government fees and requirements can change, and the exact amount depends on the project and the applicable agency requirements.

Step 5: Submission and review

Once the required information and traffic-control documents are prepared, the permit package is submitted for review. The reviewing agency may approve the submission, or it may ask for clarification, corrections, or additional information.

This is a normal part of the permitting process. It does not necessarily mean anything was done incorrectly. Reviews often lead to simple edits, additional details, or adjustments to the plan.

Corrections and plan revisions

If requested corrections can be handled within the scope of the original plan and the plan remains within the originally contemplated page count, those normal corrections are handled as part of completing the plan.

If the corrections materially expand the scope of the work or require additional plan pages, additional preparation charges may apply at $300 per additional page.

Step 6: Permit approval and traffic-control requirements

Once the permits and the approved traffic-control plan are in hand, Washington Tree Services can determine what will actually be required on the day of the tree work.

This is a critical point in the process.

We generally cannot provide a reliable final traffic-control implementation price until we have the permit requirements and traffic-control plan in front of us. Until then, any quote would be a guess.

The actual traffic-control cost can depend on several factors, including:

• Number of flaggers
• Signs
• Cones and channelizing devices
• Barricades
• Lane closures
• Pedestrian routing
• Traffic-control vehicles or equipment
• Setup and breakdown time
• Duration of the work
• Required work hours
• Number of intersections affected
• Detours or other special requirements

Step 7: Traffic-control plan vs. traffic-control implementation

This is one of the most important concepts to understand.

The traffic-control plan is the document that shows how traffic will be controlled. It is the written plan explaining the traffic management strategy.

The traffic-control implementation is the actual people, equipment, signs, cones, barricades, flaggers, setup, operation, and removal of the traffic-control system on the actual day of the job.

Those are two different services and two different costs.

Step 8: Customer approval and scheduling

Once the permit requirements and traffic-control plan are known, Washington Tree Services can build the traffic-control implementation quote. That quote is then presented to the customer for review and approval.

After approval, we coordinate:

• Permit requirements
• Traffic-control provider
• Washington Tree Services crew
• Equipment
• Schedule
• Work dates and hours

Step 9: The day of the tree work

On the day of the project, the traffic-control team arrives and establishes the approved work zone. Depending on the approved plan, this may include signs, cones, barricades, flaggers, lane restrictions, pedestrian controls, temporary traffic stoppages, or other required measures.

Once the work zone is properly established, Washington Tree Services performs the tree work. After the tree operation is complete and the roadway can safely return to normal operation, the traffic-control equipment is removed and the roadway is reopened according to the applicable requirements.

A simple example

Here is a simple, hypothetical example to make the process easier to understand.

How long does the process take?

The timeline depends on the project. There is no single guaranteed turnaround time for every Seattle tree-removal project. Timing can vary based on:

• Project complexity
• Plan preparation time
• Agency review time
• Whether corrections are requested
• Complexity of those corrections
• Permit approval timing
• Traffic-control provider availability
• Washington Tree Services scheduling

Some projects move faster than others. A simple residential tree job may take less time than a more complicated project involving a busy road, public sidewalks, pedestrian routing, or lane restrictions.

Why can’t you give me the traffic-control price up front?

This is one of the most common questions we hear, and it is a fair one.

The reason is that we first need to know what the approved traffic-control plan requires. If we guessed too early, we could give a customer a number that turns out to be wrong. A traffic-control plan can require more flaggers, more signage, different lane configurations, specific pedestrian controls, or a larger closure than expected.

If we gave a number based on an assumption and then the approved plan required more work, the estimate would not be accurate. We would rather determine the actual requirements and then provide a realistic traffic-control quote.

What am I paying for?

1. Tree work: The actual tree removal, pruning, hazard mitigation, or other service being performed.
2. $250 permit submission fee: Washington Tree Services' administrative and submission portion of the permitting process.
3. Traffic-control plan: Preparation of the required traffic-control or mitigation documentation. Pricing is $300 per page.
4. Government permit fees: Any applicable Seattle or city fees, charged separately.
5. Traffic-control implementation: The actual people, equipment, signage, cones, barricades, flaggers, setup, operation, and removal required to implement the approved traffic-control plan on the day of the project.

Final takeaway

When tree work affects a Seattle street, there can be more involved than simply showing up and cutting the tree. There may be route planning, traffic-control documentation, agency review, corrections, permit approvals, and then the actual field implementation needed to keep the public safe.

Washington Tree Services helps customers navigate that process. We evaluate the project, determine when public-street impacts are involved, begin the permitting work, prepare the traffic-control plan, coordinate with the permitting authority, and then move to the final traffic-control implementation quote once the requirements are known.

That process is why we often cannot tell you the exact traffic-control price before the permit requirements and plan are complete. We would rather do the work correctly, with the right plan and the right traffic-control setup, than guess and give you an inaccurate number.

If your Seattle property has a tree near the roadway, sidewalk, or a public street, contact Washington Tree Services so we can evaluate the tree, the access needs, the equipment requirements, and any potential traffic-control needs before the work begins.

Frequently Asked Questions

Why do I need traffic control for tree removal?

Because the work may affect public travel, pedestrian movement, or the safe use of a roadway. If a tree is near a street or requires equipment in the road, traffic control may be necessary.

Who determines whether traffic control is required?

The project conditions, site layout, and permitting requirements help determine this. Washington Tree Services evaluates the site first, and the reviewing authority may also impose requirements.

Is the $250 permit submission fee the same as the Seattle permit fee?

No. The $250 fee is Washington Tree Services' permit-submission and administrative fee. City or agency permit charges are separate.

How much does a traffic-control plan cost?

The pricing is $300 per plan page, with example pricing of $600 for a two-page plan and $900 for a three-page plan.

Why don’t I know how many pages my plan will require immediately?

Because the number of pages depends on roadway complexity, lane configuration, pedestrian needs, equipment placement, and permit review requirements.

What is the difference between a traffic-control plan and the traffic-control crew?

The plan is the written document detailing how traffic will be managed. The crew is the actual field team that installs the signs, cones, barricades, and flaggers on the day of the job.

Can Washington Tree Services tell me the final traffic-control cost before permit approval?

Usually not. The final implementation cost often depends on the approved permit requirements and plan.

What happens if Seattle requests corrections?

Normal corrections may be included within the original plan scope. If the corrections expand the plan significantly, additional page charges may apply.

How long does the permitting process take?

It depends on project complexity, agency review, corrections, and scheduling. There is no single guaranteed processing timeline for every project.

Does every tree removal project need traffic control?

No. It depends on whether the project affects a public street, travel lane, sidewalk, or other public-right-of-way conditions.
