Summary Report 02/15/2024
As part of my On-Call Arborist responsibilities with Yountville, I review trees at the request of Yountville Staff. John Ferons, DPW Director, contacted me about 15 Redwood Trees in the Oak Leaf Court area. I inspected the trees and site on February 7, 2024.
There had been several tree failures, causing some property damage.
This Arborist Report details my findings and recommendations. The site is west of Heather Street but past the street trees and over a flowing creek.
This photo shows Tree #10's trunk but reveals the creek level and the trees on Heather Street.

My survey started with the first Redwood next to the pedestrian bridge, the north end of the Redwoods. A tree service removed one large Redwood Tree and stump at the end of Oak Leaf. This Redwood had failed and damaged a parked vehicle. There had been other branch failures within the last week, which prompted my visit.

Conclusion
The past care for the redwood trees should change more positively for the Redwood Trees. Limbing up trees is not a good idea as it puts more force on the trunk and root system. Pruning, especially thinning, and removing whole branches should be avoided.
These trees are a mixed bag, some in poor condition and others pretty good. My recommendations below are just that; I can only advise and recommend. The Town of Yountville has to decide what their risk tolerance is. It's your decision, and since there have been several tree failures recently, the decision may be to remove all 15 trees.
Trees 1 through 3 are sustainable and low-risk trees. Trees 5, 6, 7, 8, 9, 10, and 15 are also low-risk and sustainable.
I recommend that Trees #4, 11, 12, 13, and 14 all be removed due to decay, included bark and weakly attached co-dominants.
