What Commercial Tree Work Can We Handle on Mercer Island?

We combine tree work that would otherwise require several separate service calls into one commercial scope.

That can include:

• Scheduled commercial tree trimming and pruning
• Dead and broken branch removal
• Clearance over buildings, sidewalks, parking, and access routes
• Tree risk assessments
• Commercial tree removal
• Commercial stump grinding
• Storm-damaged tree work
• Parking-lot tree care
• Approved lot and site clearing
• Tree inventories
• Construction-related tree work
• Landscape restoration after removal
• Recurring commercial tree-maintenance contracts

The scope should identify the trees or areas involved, what work is authorized, how debris will be handled, what requires separate approval, and any access or scheduling restrictions.

For broader regional commercial service information, see our King County commercial tree care.

Tree Care for Mercer Island HOAs and Multifamily Properties

HOA and multifamily tree care works best when the property is managed as a tree population instead of a series of unrelated calls.

Common areas may contain mature trees beside buildings, sidewalks, parking, play areas, drive aisles, neighboring properties, and resident gathering spaces.

We can help boards and property managers separate immediate concerns from planned maintenance.

Typical scopes include:

• Common-area pruning
• Deadwood removal
• Parking and walkway clearance
• Building clearance
• Assessment of damaged, leaning, or declining trees
• Planned removals
• Stump grinding
• Storm work
• Multi-tree assessments
• Tree inventories
• Recurring maintenance

What Is a Tree Inventory?

A tree inventory is a documented record of trees on a property that helps managers organize condition, priority, and recommended work.

Depending on the agreed scope, it may include:

• Location
• Species
• Approximate size
• Condition
• Priority
• Recommended work
• Previous work where records are available

An inventory is most useful when it leads to decisions.

It can help the board distinguish a broken limb that needs immediate attention from routine pruning that can be planned for a later budget cycle.

Where a particular tree needs formal risk documentation, we can determine whether a separate arborist consultation or tree risk assessment is appropriate.

When Does a Commercial Property Need a Tree Maintenance Agreement?

A recurring tree-maintenance agreement makes sense when a property has enough predictable work that quoting every pruning or maintenance visit separately creates unnecessary administration.

MTS Tree and Landscape offers ongoing commercial contracts with scheduled service, documented work, and after-hours scheduling for qualifying projects.

Scope structure	Useful when	How work is authorized
Recurring maintenance scope	The property has predictable pruning and maintenance	Agreed work is scheduled, with separate approval for additions
Site-specific annual plan	HOA or manager wants to prioritize multiple trees	Work is organized by condition, priority, and available budget
On-call commercial service	Tree needs are occasional	Individual jobs are quoted or authorized as needed
Construction/project scope	Tree work follows a defined development or renovation	Work is authorized by project phase and approved tree plans

A commercial agreement should not simply say “maintain trees as needed.”

It should define what is included and how additional work gets approved.

What Should a Commercial Tree-Care Proposal Include?

A useful proposal gives the board, manager, GC, and tree crew the same understanding of the job.

Before approving a commercial tree-service proposal, confirm:

• Property addresses included
• Trees or work areas included
• Pruning, removal, assessment, or stump scope
• Debris and wood handling
• Access requirements
• Parking restrictions
• Pedestrian or tenant restrictions
• Permitted work windows
• Permit responsibility
• Additional-work approval
• Emergency contact process
• Pricing structure
• Required documentation
• Insurance or COI requirements
• Important exclusions

This becomes especially important when bids look different.

One contractor may include stump grinding, debris haul-away, traffic control, after-hours work, or site restoration while another does not.

Compare the scope before comparing the total.

Commercial Tree Pruning, Removal, and Stump Grinding

A commercial tree project often combines several services in one mobilization.

Commercial Tree Trimming and Pruning

The pruning objective should be written into the scope.

That may include:

• Deadwood removal
• Structural pruning
• Building clearance
• Parking-lot clearance
• Walkway clearance
• Corrective pruning
• Selective crown reduction
• Storm-damaged branch removal

A tree beside a parking lot may only need lower branches raised. Another tree may need one overextended branch reduced rather than the entire canopy thinned.

See our tree trimming and pruning services for more detail on pruning methods.

Commercial Tree Removal

Commercial tree removal can involve climbing, rigging, crane support, occupied areas, vehicles, buildings, narrow access, or phased cleanup.

The proposal should state what happens from setup through final debris removal.

See our tree removal services for broader removal capabilities.

Commercial Stump Grinding

Stump grinding can be included with removal or quoted separately.

The intended use of the area matters. A stump in a future planting bed, lawn, walkway, parking improvement, or construction area may require a different scope.

Commercial properties should also confirm whether chip removal, backfill, utility locating, and restoration are included.

How Much Does Commercial Tree Care Cost on Mercer Island?

Commercial tree care is usually quoted from the defined scope, but current MTS regional pricing gives useful planning ranges. Routine tree pruning often starts around $150 to $1,500 or more per tree, standard removals commonly run $500 to $5,000 or more, and commercial stump grinding generally runs $200 to $1,500 or more per stump.

Very large or technically difficult work can exceed those figures substantially.

Service	MTS regional planning range
Routine pruning	$150-$1,500+ per tree
Large or complex pruning	$1,500-$3,500+ per tree
Standard tree removal	$500-$5,000+ per tree
Very large or complex removal	$5,000-$15,000+
Commercial stump grinding	$200-$1,500+ per stump
Recurring commercial maintenance	Site-specific proposal
Multi-tree or construction scope	Site-specific proposal

These are regional planning ranges, not fixed Mercer Island commercial rates.

Commercial pricing changes with:

• Tree count and size
• Pruning versus removal
• Rigging or crane requirements
• Site access
• Occupied buildings
• Parking or traffic control
• After-hours scheduling
• Debris volume
• Stump work
• Permit requirements
• Construction coordination
• Required documentation

For recurring properties, the better question is usually not “What is the price per tree?” but “What work belongs in this year's approved scope?”

Request a commercial site walk-through or bid.

Tree Risk Assessments and Work Planning

A tree risk assessment evaluates the tree in relation to the people, structures, vehicles, or other targets that could be affected if part of it fails.

The purpose is not to label every mature tree dangerous.

The recommendation may be:

• Pruning
• Monitoring
• Managing access beneath the tree
• Additional investigation
• Removal where appropriate

Our team includes Alexander Lasko, ISA Certified Arborist PN-7704A (TRAQ).

For a property with many trees, an inventory and risk-based work plan can help separate urgent findings from maintenance that can be scheduled.

Tree Care for Construction Projects on Mercer Island

Tree decisions should be resolved before clearing, grading, trenching, and excavation begin.

Mercer Island regulates development-related tree removal and tree protection, and the approved plans may determine which trees remain, which can be removed, and how retained trees must be protected.

Our construction tree scope can include:

1. Reviewing the approved tree-work requirements
2. Completing permitted removals
3. Working around required Tree Protection Zones
4. Selective site and lot clearing
5. Stump grinding
6. Tree work coordinated with access, utilities, and grading
7. Post-construction pruning or landscape restoration where included

The City provides current development-tree requirements through its tree permits related to development proposals.

Arborist Reports and Tree Protection Plans

Formal development-arborist work is a separate professional scope.

Mercer Island has specific qualification requirements for arborists preparing development reports and prescribing construction-tree protection.

If your project requires an arborist report, tree-protection plan, monitoring, or formal City documentation, send us the City's request and project documents before assuming that work is included.

We can confirm our qualified scope and coordinate tree operations with the project's separate qualified arborist when one is required.

Mercer Island Tree Permits and Right-of-Way Work

Commercial ownership does not create an exemption from Mercer Island's tree rules.

Trees on Private Commercial Property

For non-development work, the City's current rules generally require a tree permit when removing:

• A tree 10 inches DBH or larger
• An exceptional tree
• A tree in a critical area

Small trees outside critical areas may qualify for an exemption.

Normal pruning on private property can also be permit-exempt when it stays within Mercer Island's definition of normal maintenance, including the City's 25% leaf-area limit.

Review current requirements on the City's tree permit page before removal.

Street and Right-of-Way Trees

The City right-of-way can include streets, sidewalks, paths, shoulders, and sometimes an area that visually appears to be part of the adjacent property.

Trees in the ROW are regulated by the City.

Before pruning or removing one, the City requires approval. If the proposed work is allowed, the applicant must submit the appropriate ROW tree application and ROW Use permit.

See Mercer Island's street tree pruning and removal guidance.

Do not schedule a suspected ROW tree as ordinary private-property work until ownership and permit requirements have been confirmed.

Can Work Be Scheduled Around Residents, Tenants, and Business Operations?

Yes, commercial tree work can often be scheduled around site operations, and MTS Tree and Landscape offers after-hours scheduling for qualifying projects.

The proposal should identify constraints such as:

• Resident parking
• Customer traffic
• Loading zones
• Deliveries
• Pedestrian routes
• Gate access
• Noise restrictions
• Equipment staging
• Areas that cannot be blocked

The more of those restrictions we know before pricing, the more accurately the proposal can reflect the real job.

Why Work With MTS Tree and Landscape?

We've served King County since 2005 and provide commercial tree service for HOAs, property managers, office and retail properties, multifamily communities, and construction projects.

MTS Tree and Landscape is licensed, bonded, and insured in Washington under contractor registration SOUNDPL826DZ and UBI 603554491.

Commercial clients can also verify Washington contractor registration through the Department of Labor and Industries.

For commercial work, the important difference is coordination.

We can build a scope around:

• What needs to be done
• Which trees take priority
• Who can authorize additional work
• How crews access the property
• When work can occur
• What cleanup is included
• What documentation is expected
• Which permits or approvals apply

That gives the board, property manager, or project team a clearer basis for approving and managing the work.

Mercer Island Commercial Tree Care FAQs

How much does commercial tree care cost on Mercer Island?

Commercial tree care on Mercer Island commonly starts around $150 to $1,500 or more per tree for routine pruning, $500 to $5,000 or more for standard removal, and $200 to $1,500 or more for commercial stump grinding. Large, complex, multi-tree, and recurring scopes are quoted from a site assessment.

What is included in a commercial tree-maintenance contract?

A commercial tree-maintenance contract can include scheduled pruning, inspections, removals, stump grinding, documented work, cleanup, and a defined process for approving additional services. The agreement should also state the properties covered, access restrictions, work windows, emergency contacts, pricing structure, and exclusions.

Can commercial tree work be scheduled outside normal business hours?

Yes, MTS Tree and Landscape offers after-hours scheduling for qualifying commercial tree projects. Availability depends on the site, equipment, local work restrictions, crew schedule, and scope. Tell us about tenant, resident, customer, parking, or delivery constraints before the proposal is prepared.

Does MTS Tree and Landscape provide construction arborist reports?

MTS Tree and Landscape can provide arborist services within our qualified scope, but Mercer Island has additional qualification requirements for certain development reports. Send us the City's request first so we can confirm whether we can prepare the document or should coordinate with the project's separate qualified arborist.

How early should a construction project address tree work?

Construction teams should resolve retained trees, approved removals, Tree Protection Zones, access, and stump conflicts before clearing or excavation begins. Addressing trees during pre-construction planning reduces the risk of discovering permit restrictions or root-protection requirements after grading, utilities, and site access have already been laid out.

How do we request a commercial tree-care proposal?

Call (425) 369-8733 or submit the MTS Tree and Landscape contact form to request a commercial site walk-through or bid. Provide the property address, number of sites, known tree work, access restrictions, bid deadline, insurance requirements, and any tree, permit, or construction documents already available.
