Land Development and Trees
Helping People Make Informed Decisions About Trees
When proposing the construction of roads, buildings, landscape or additions near existing trees it is often necessary to have the project assessed by a qualified arborist.
Trees are assessed for size, health and condition and the proposed development project is assessed as to its impact on these existing trees (i.e. tree removal, root loss, etc...).
These arborist reports are often required by the governing body, such as the city or county, and as a condition of permit approval.
To find out if your project requires an arborist assessment check the City or County tree ordinances where the proposed project is located (See ORDINANCES in the RESEARCH area of this website).
  • Initial Tree Inventory and Assessment
    • All trees are individually identified and represented on a spreadsheet with summaries for quick analysis of the resource.
    • An up-to-date and accurate assessment of trees by their health and condition. They are given a rating of suitability for preservation and a tree protection radius. This provides the design team with a description of what trees can, or should be, preserved and how close to build without special considerations.
    • General guidelines with state of the art methodology to assist the design team when developing near preserved trees.
  • Design Assistance
    • Specific recommendations for architects and engineers concerning designing within the tree preservation zones including grading, foundations, soil fill, soil cuts, compaction, trenching, drainage, equipment access and storage, etc..
    • State of the art AutoCAD or hand-drawn formats available with written reports for ease of use with the design team and construction personnel,.
  • Follow-up Design Consultations
  • On-site Consultations when you need them!
  • Public appearances at meetings with planners, city councils and the public to answer questions about construction mitigation measures.

Damage/Loss Appraisals
"Helping People Make Informed Decisions About Trees"
Trees and landscape do have monetary values and there are industry standards to calculate their value and loss.
Tree appraisals are provided for assessing tree loss due to fire, storms, landslides, root damage, vehicle damage, vandalism, poisoning, disease, improper pruning or unapproved tree removal.
It is important to take pictures of loss or damage as soon as possible, then consult with an experienced arborist/horticulturalist.
If you currently have no damage at this time... take pictures anyway!
This information will help you document the contribution of trees and landscape on your property. Pictures should be taken from different areas of the home and property. Include how trees and landscape frame views, provide screening or privacy, and photos that can help give a visual record of the size and health of particular trees.
