Tree Risk Assessment, Arboricultural Consulting & Permit Acquisition
Posted by xanthocyparis
We offer a number of consulting services for homeowners and property managers. Whether you require a Certified Arborist report, a Tree Hazard Evaluation report, a tree disease diagnosis, a tree inventory or management plan, the arborists at Ward Tree Care can help you. We are available for free estimates on all work, and can provide professional tree care advice for individual trees to large tree collections.
We offer Tree Risk Assessments by a Certified Arborist having Tree Risk Assessment qualifications administered by the International Society of Arboriculture. In addition to visual tree assessment (usually all that is needed), we can arrange more advanced techniques of structural analysis including sonic tomography and resistograph measurement should they prove necessary. Here is a link to a video we took of the use of sonic tomography on a large cavity in a Grand Fir in West Linn. The homeowner chose to retain the tree.
Many municipalities in the Portland Metro area require a permit for removing or pruning trees. Permitting can be based on the size and the location of the tree, whether the tree is a hazard, whether it is a street tree, an invasive species, dead or dying, or whether your property adjoins other environmental overlays such as greenspaces or wetlands. The arborists at Ward Tree Care can help you determine whether permits apply and assist you in obtaining the relevant permits. Below are a few links to help you in determining what permits may be needed.
