Risk and Safety FAQs

A tree risk assessment is a structured evaluation of tree defects, site conditions, and targets to determine practical risk mitigation options.

• We inspect the crown, trunk, unions, and root zone for defects and contributing factors
• We consider site exposure, soil conditions, and how often targets are present
• We provide mitigation options such as pruning, support systems, monitoring, or removal when warranted
• The goal is practical risk reduction, not fear-based decisions

Tree risk is the combination of failure potential, the chance of impact, and the severity of consequences.

• A defect alone does not define risk, targets and occupancy matter
• A tree over a play area is different from the same tree over an unused corner of a yard
• Risk changes over time with growth, weather, soil moisture, and site changes

Certain changes justify a prompt on-site evaluation, especially when targets exist.

• Fresh cracks in trunk or major limbs
• A new or increasing lean, especially with soil movement
• Soil lifting, sinking, or newly exposed roots on one side
• Large dead limbs over driveways, sidewalks, roofs, or play areas
• Mushrooms or conks at the base, particularly on large mature trees
• Recent construction or trenching within the root zone followed by decline

Yes. Some failures occur from hidden defects, root problems, or sudden weather loads.

• Internal decay can exist with minimal external symptoms
• Root damage and poor soil conditions are often not obvious from the canopy alone
• Some species have known failure patterns, especially with poor structure or past topping
• A professional assessment focuses on structure and site context, not just leaf color

A target is anything that can be damaged or injured if the tree or a part of it fails.

• Common targets include homes, cars, sidewalks, patios, play areas, and utility services
• Target occupancy matters, how often people are present changes the risk profile
• Good mitigation planning prioritizes risk reduction where targets are highest

Cracks can indicate stress, separation, or an active failure process, and they should be evaluated promptly.

• Fresh cracks, widening cracks, or cracks with movement are higher concern
• Cracks near major unions, especially with included bark, can be significant
• If there is audible creaking, visible separation, or hanging limbs, restrict access and schedule urgently

A lean can be normal, or it can indicate root failure potential, depending on whether it is recent and whether the root plate is moving.

• A long-standing lean with stable soil and good root anchorage may be manageable
• A new lean after rain or wind, especially with soil disruption, is a higher concern
• Lean direction relative to targets affects mitigation priority
