Tree Inventory

The purpose of tree inventory is to provide a baseline upon which management of the trees will occur.  In the inventory, a health assessment and location of trees is inspected and collected. Notes are provided for care options ranging from pruning, cultural care, removal, new plantings, or tree protection. The number of trees can range from a few to hundreds of thousands, all depending on the client’s needs.

The general process is as follows:

  • Identify and GPS locate trees;
  • Assess condition of trees and site;
  • Provide maintenance options including cultural practices to improve health; and
  • Prioritize trees based upon tree health and structural findings.

Tree Risk Assessment

The purpose of a tree risk assessment is to inspect and assess in detail the structure and quality of the tree, tree parts, surrounding targets, and environmental conditions. This assessment will provide the tree owner with options for mitigating or reducing risk associated with the tree. This service follows the ISA Tree Risk Assessment Best Management Practices, and is performed by ISA TRAQ Qualified Certified Arborist to assess the trees. The assessment protocol has 3 levels depending on the client needs, and can range from an individual tree to a full population of trees. Contact us to determine which level is right for you.

The general process is as follows:

Risk Assessment

  • Understand the Tree Manager’s risk tolerance for tree failure
  • Assess tree structure, target, and risk analysis;
  • Provide mitigation options to reduce risk; and/or
  • Prioritize population by risk ratings.

Failure Investigation

  • Investigate cause of tree, branch, or tree part failures;
  • Provide thorough objective report; and
  • Provide management options for other trees and/or conditions on the site.

Tree Protection during Construction, with Specifications

The purpose of tree protection specifications is to help protect trees from adverse site modifications during construction that would be detrimental to the health and survival of the tree. These specifications include the services provided under the Tree Inventory service with additional information and recommendations on which trees to preserve or remove, with or without mitigation requirements based on the tree ordinances for the governing agency.

The general process is as follows:

  • Review development plans to determine the need for construction protection;
  • GPS locate, map, tag, and measure trees;
  • Develop General Tree Protection measures;
  • Coordinate with engineers or planners to assess impacts and mitigation requirements;
  • Review site plans to assure protection measures are established and implemented; and
  • Monitor tree preservation on site.

Tree Appraisal

The purpose of a tree appraisal is to determine the monetary value that a tree has for replacement, negotiation, and litigation. This appraisal is valuable for clients that have trees impacted during fire, storms, trespassing or other causes. CalTLC follows industry protocols to determine the value and clearly describes the process used to formulate the value. The thorough description of the process to determine the value is typically what supports the stated values.

The general process is as follows:

  • Understand the assignment, or need for the appraisal;
  • Determine the appropriate Method for appraising value;
  • Provide expert data collection for appraisal;
  • Provide a monetary value for the tree; and
  • Provide a written report explaining the appraisal.

The purpose of providing expert witness and consulting services is to provide an objective research and testimony for litigation cases involving tree related issues. These services may arise for tree appraisals, sidewalk or pavement damage, causes of tree failure, comparing work procedures to industry standards, and incidence or cause of disease or insect infestations.

The general process is as follows:

  • Determine objectives of clients’ needs;
  • Conduct field research;
