Certified arborists also document findings and help ensure local compliance where permits or records are required.
Certified Arborist Assessment for Tree Removal
Has been determined to be such by a certified arborist. If the tree has been determined to be dead, removal is permitted under Section 8.10.050 of the Palo Alto Municipal Code.
Tree Technical Manual, 2001
These professional standards reduce risk and support efficient removal operations.
Removal work follows a clear sequence to protect property and meet requirements.
Understanding these steps helps owners plan scheduling, costs, and any restoration.
Emergency removal is needed for storm-damaged trees, fallen limbs blocking access, or trees posing imminent collapse risk. Dunbar prioritises site safety and rapid mitigation.
A rapid-response team secures the scene and removes hazards efficiently.
Emergency operations use structured risk assessment and protective measures to safeguard crews and the public.
These protocols minimise injuries and property damage while enabling safe operations.
Dunbar maintains staffing, equipment, and dispatch procedures to respond quickly after storms.
This approach reduces additional damage and speeds site recovery.
Professional trimming corrects structure, removes deadwood, and reduces branch-failure risk to protect people and property.
Regular trimming supports structural stability and long-term tree health.
Certified pruning follows ANSI A300 standards to preserve form and encourage healthy regrowth.
Following certified methods helps maintain safe, resilient trees.

Late winter to early spring, while trees are dormant, is generally best to reduce pruning stress and promote healthy regrowth.
Coordinate timing with an arborist for species-specific recommendations.
Stump grinding removes visible stumps, improving safety and aesthetics while freeing space for landscaping.
Specialised grinders typically remove the stump to below grade for smooth reintegration with the yard.

Overall, stump grinding supports safer, more usable outdoor space.
Dunbar pairs commercial-grade stump grinders with ISA-certified arborists to remove stumps efficiently while protecting the surrounding site.
This combination minimises disturbance and returns the site to usable condition.
Check certifications, insurance, and references; confirm ISA-certified arborist availability and get written estimates to compare scope and cost.
Typically at least once per year; frequency varies with species, growth rate, and tree condition—your arborist can recommend intervals.
Look for decay, persistent dead limbs, severe lean, major storm or pest damage, or conflict with structures—an arborist should assess and advise.
Homeowners can do minor pruning, but elevated, large, or complex work should be handled by professionals for safety and long-term tree health.
Costs depend on size, location, and condition; residential removals commonly vary widely—obtain multiple quotes to compare services and pricing.
Clear obstacles, notify neighbours if needed, keep pets and children indoors, and confirm whether permits or utility notifications are required.
