| Welcome to the Consultant House! |   |
||||||||
David Reich, Lead Consultant CFI’s consultation services can be divided into four basic categories: |
|||||||||
We often provide project management and permit acquisition consultations
in conjunction with one another. |
|||||||||
Hazard Evaluation: |
|||||||||
A tree can either pose a hazard to adjacent property and persons because of its poor condition or because its position in a given landscape causes a hazardous condition. In other words, a healthy tree in sound structural condition can still cause a hazardous condition. A tree that interferes with power lines or obstructs traffic safety signals or motorists’ visibility exemplifies such a situation. Sometimes remedial action, like pruning, can correct such a hazard. Sometimes nothing short of removal will fix the problem. |
|||||||||
Typical situations that require our hazard evaluation services include the following:
|
|||||||||
CFI usually employs the hazard rating format developed by Clark and Matheny published by ISA, which has come to be the industry’s professional standard. Remember that without a target in striking range of a tree, little or no hazard exists. The rating system we use considers equally the target and the tree. |
|||||||||
Tree Appraisal and Expert Witness: |
|||||||||
Tree appraisal puts a monetary value on one or more trees or large woody shrubs. Typical situations that require our appraisal services include: |
|||||||||
|
|||||||||
The ISA publishes a guide for tree and plant appraisal called the Guide for Tree and Plant Appraisal (known as “the Guide”), updated most recently in 2000. Then Guide provides several different methods for proper evaluation of tree or plant damage depending on the nature of the damage and of the site. Importantly, the Guide details proper application of the Trunk Formula Method for appraising trees too large to evaluate any other way. |
|||||||||
Project Management: |
|||||||||
Wherever major land development impacts trees on or near the site, developers and/or public agencies will rely on a consulting arborist to manage the project as it affects those trees. Changes in sun and wind exposure and drainage patterns along with damage to large critical root zones constitute the major problems addressed by the arborist. Other situations that may require the management services of an arborist include: |
|||||||||
|
|||||||||
Professional services provided by a CFI consulting arborist to a developer or a public agency might include: |
|||||||||
|
|||||||||
Permit Acquisition: |
|||||||||
Some governing agencies now require a well-qualified arboricultural review of any project that impacts, or may impact, trees. In order to accelerate the permitting process, we provide a hazard evaluation to hasten the removal of a dangerous tree or a full-blown restoration plan for a greenbelt clear-cut. A CFI consulting arborist can acquire the needed permits on your behalf with a minimum of inconvenience and wasted time at the permit counter. |
