Gold River, CA
We conducted a risk assessment and developed management guidelines for 352 trees belonging to the Gold Spike Village Association. The report we provided characterized tree health, assessed the risk the trees posed to people and property, and indicated their potential for damaging hardscape. We also offered specific recommendations to improve tree health and reduce the risk of damage by the trees.
San Jose, CA
The Santa Clara Valley Water District hired Tree Associates to provide a risk assessment and hazard abatement recommendations for four California sycamores located in their corporation yard. We made a visual inspection of the trees, removed soil pneumatically to inspect the roots near the base of the trunks, and assessed internal decay of roots, limbs, and trunks using a Tree Radar Unit and a drill. Our report documented the extent of decay and other tree defects, indicated the hazard the trees pose to people and property, and recommended corrective actions to eliminate or mitigate risks.
Shields Oak Grove Case Study, University of California, Davis
The UC Davis Shields Oak Grove is the only large collection of mature oaks in the western United States. In order to ensure the long term preservation of these valuable trees, the University Arboretum asked Tree Associates to evaluate the condition and management of the Grove, which was established in the 1960s.
The following items were of specific interest to the Arboretum staff:
• The current health of the trees
• The impact of large numbers of nesting herons on the health of the trees
• The structural integrity of the trees and associated risk to the public
• Current management of the grove (irrigation, pruning, fertilization, etc.)
• Treatments to improve tree condition for the long term
