Tree inventories involve geo-locating trees and collecting data about size, species, health, condition, location, and/or impact from construction.
Accurate information about trees provides the property owner with knowledge that is essential to manage and maintain one of the most critically important natural resources on the site. In addition, many local ordinances require that a tree inventory and tree protection plan be completed before a site disturbance permit is issued. During the inventory process, all trees over a specified diameter will be identified and numbered with a small aluminum tag. Trees can be geo-located by a surveyor, or Arborguard’s Construction and Development Team (C&D Team) can locate the trees using our own GPS equipment. Once identified and tagged, trees are assessed by an Arborguard C&D Team Arborist for a variety of information fields that can be customized for the site or to comply with the requirements of any prevailing ordinance.
It’s critical that tree information is accurate and it takes an experienced Arborist to get it right.
In many cases, errors in information can cost money, either through fines, stop work orders, or by paying too much recompense. Many ordinances exclude certain species from their tree protection requirements and also delete recompense charges for trees that are dead, dying, or hazardous. (DDH trees) Its important that a qualified Arborist thoroughly inspect each tree or else the owner may be paying recompense charges for a tree that would otherwise be exempt. In many cases only an experienced Arborist can identify a hazardous tree, condemn the tree, support the analysis, and avoid recompense charges. It is not unusual for a client to save 30% or more in recompense charges with an accurate survey. On one large property Arborguard saved a developer over $250,000 in recompense just by reviewing the data collected by a survey crew and deleting DDH trees! With this effort alone, we paid for our fees for the entire project, 10 times over.
In addition, an accurate tree inventory can help designers place buildings and infrastructure in non-wooded areas or away from specimen trees. Critical root zones can also be identified using inventory information. This information can be used as part of a Tree Preservation Plan to protect and preserve existing trees to give the completed project a natural appearance that improves curb appeal, leasing, occupancy, sales, and increases property values. In some cases, by saving trees and protecting natural areas, LEED credits may be earned. Our C&D Team of Arborists includes a Registered Landscape Architect, a LEED Board Certified Master Arborist, and an ISA Certified Arborist who are all experts in construction and can work seamlessly with the rest of the development team. We have full Auto-cad software and in house plotter capabilities to process PDF files or to create full size blueprints, prepare documents, or modify existing design or construction drawings.
