Informational Site Visit:

An Informational Site Visit with Cerified Arborist Andrew Craig provides homeowners and property managers with the information they need to make informed decisions about Tree Care, as well as the health and vitality of their entire landscape. During an Informational Site Visit, property owners create their own documentation and notes as needed to fulfil their landscaping and tree care plans.

Perfect for homeowners and property managers who need information and guidance regarding landscaping plans, tree health, plant & shrub selection, or tree hazard analysis, an Informational Site Visit is an inexpensive alternative to our Formal Consultations that do include a written report. Site Visits generally provide ample time to discuss one or many aspects of your landscape and tree health.

Certified Arborist Formal Site Consultation with Written Report:

For any construction project, insurance claim, or other formal site planning or evaluation, written reports and documentation by a Certified Arborist are often neccessary. Formal Site Consultations with a Written Report include the documentation that is required to support building permits, homeowners claims, or even litigation. For more than 20 years, Springwater Arboriculture has provided trusted and accurate documentation and reports for Portland, Oregon area developers, homeowners, property managers, and goverment agencies, including:

  • tree protection plans
  • risk rating assessments and target evaluations
  • tree canopy surveys, tree map reports
  • Tree appraisals
  • insurance claims
  • timber trespass reports

Features & Benefits of Certified Arborist Site Consultations:

Tree & Plant Identification / ID

Because many aspects of tree and plant care is species-specific, it is important to be able to identify the genus, and even better: the species and cultivar of the tree or plant. Accurate identification helps determine proper pruning regimes, and other ‘cultural’ aspects such as water-needs, soil tolerance, common pests, sun or shade exposure.

Tree selection:

With an onsite evaluation we can recommend an appropriate tree for mitigation purposes or for an addition to your landscape. We believe in the power of the Right Tree in the Right Place.

Tree Health and Plant Health / Disease and decay diagnosis:

Concerns the health of trees and plants can include symptoms like chlorotic foliage, dripping from leafs, early needle or leaf drop, abnormal growth, sap flowing from bark, or maybe your tree just looks bad. With a simple Informational Site Visit, many problems can be accurately diagnosed, and a plan of action recommended.
If further information is warranted, leaf, root, tissue and soil samples can be collected and sent to a lab for a more thorough diagnosis. We will provide appropriate collection of samples and their delivery to the lab, and meet with you when a diagnosis is rendered. At this time an accurate plan of action can begin.

Tree and infrastructure conflicts;

When tree roots encounter sidewalks, driveways and foundations, an on-site assessment can help determine a safe course of action, and also provide any documentation that may bee needed for tree- or root-cutting permits or insurance claims.

Tree and plant appraisal; Insurance Assessment and Evaluation:

When a loss of a large tree occurs, or damage is so extensive removal is necessary, we can help establish lost value and replacement value. If damaged trees and shrubs are smaller and commercially available we can determine replacement value. We also provide any documentation that may be needed for tree-cutting/removal permits, and also the assessment and evaluation needed for homeowners insurance claims. If a loss occurs we can prepare a report that describes tree and condition prior to loss and the tree’s value.

Construction planning and protection:

For construction and property development projects, building permits require site work involving an inventory of all trees 6-in DBH and greater, mapping of tree locations, and a condition report. The tree map and inventory is then compared to site development plans, and recommendations are made for tree retention and protection or tree removal. Recommendations are also made concerning tree pruning, and hazard mitigation of retained trees. A protection plan is made outlining tree protection, fencing, and instructions for protecting tree from site development, building construction and landscape installation.

Tree risk assessment:

Assesing the risk a tree poses, either in general or to a ‘target’ structure, can be simple or extremely complex; Springwater Arboriculture is able to provide the level of risk assessment scope as desired by the property owner, but usually do include a written report valid for the date of assessment.
During a tree risk assessment, we visually inspect the tree from its root zone, up the trunk, to the crown, looking for defects. Defects are noted and risk is assigned depending on size of defect, probability of failure and presence of a target. If a visual inspection still leaves too much uncertainty, we are able to provide more advanced assessment techniques, such as sounding with a mallet, using a probe or core sampler, and sonic tomography.

Tree risk mitigation:

When a Tree risk assessment yields a discenable risk, we can recommend actions that mitigate that risk. While the only way to completely eliminate a risk is to remove a tree, there is often a very workable plan of action that effectively mitigates risks to safety or property while preserving your tree; while Springwater will never fail to recommend removals when warranted, we pride ourselves in finding solutions that encourage life and vitality in your landscape. We can act as a neutral party, providing a report for mitigation measures, or we can provide a written estimate for a risk mitigation plan based on our report.

Certified Arborist Site Consultations and Reports are appropriate for:

portland metro area tree-cutting permits:

Most cities in the Portland Metro area now require permits to remove street trees and private trees on some properties. It is sometime necessary to provide these government agencies a report provided by a Certified Arborist in order to obtain such permits. These reports can include hazard assessments and any necessary mitigation measures that are required.

property development

When properties are entered into development, municipalities require detailed tree inventories and plans detailing any tree removal and protection. In some cases they require mitigation plans that include replanting and specific protections for trees when the property is being re-landscaped.

homeowner’s associations and other planned communities:

We provide a number of HOA and planned communities with tree surveys for common areas. These surveys include species identification, mapping, condition assessments, and prescribing specific actions. The surveys are valuable documents that help communities manage street trees, woodland areas, and common spaces, and keeps these shared assets safe and productive. Reports also provide such communities with the tools they need to budget for tree maintenance.


Much like the way that a home inspector provides detailed professional assessments of the elements of the house itself, a Certified Arborist provides a detailed professional assessment of the trees on the property. We provide realtors with useful and current information detailing tree health, hazards, and maintenance costs that help their clients understand what’s in store if they purchase the property.
