TREE RISK ASSESSMENT
We perform tree risk assessments to help clients understand and manage risk present in urban trees. Trees near homes and public areas carry risk along with their many benefits. Trees can fail, whether in whole or in art and cause significant damage.
Managing risk is typically a top priority for any tree owner or manager. Because urban trees are typically in close proximity to people and priority, they must be maintained so that the level of risk present is at an acceptable level.
A typical tree risk assessment includes an evaluation of the tree and surrounding site conditions, and then details appropriate recommendations. A written report is provided detailing all aspects of the assessment. A tree risk assessment can be performed on its own, or as part of a tree inventory, urban forest management plan or tree preservation plan.
We follow ANSI A300 Part 9 standards for tree risk assessment. There are three levels of risk assessment within the ANSI Standards:
Level 1: Limited Visual Assessment - an assessment of a population of trees from a specified perspective in order to identify obvious defects or specified conditions.
Level 2: Basic Risk Assessment - a detailed assessment of a tree and its surrounding site, plus a synthesis of the information collected to make management decisions.
Level 3 - Advanced Risk Assessment - an assessment consisting of a Level 2 Assessment in conjunction with advanced equipment or analysis. This type of assessment might use decay detection devices such as a Resistograph in order to determine the structural integrity of a tree.
