On Tuesday, June 12, the certified arborist was on-site monitoring during the concrete curb/asphalt removal activities around three street trees. These trees are located on the west side of Main Street/Hwy 101 south of Sherwood Road, in front of the Willits Taco House.
Two of the three trees were determined to be able to survive the excavation work required for the new sidewalk and curb. One tree (tree #2) needed a number of large structural roots to be removed to allow enough room for the sub-grade of the new curb and sidewalk. It was determined that this tree would not survive the severed roots.
Following the tree removal protocol, the City of Willits was notified and City Planner, Dusty Duley came out to the site to review the trees. The City reviewed the arborist report and agreed with the recommendation to remove tree #2 due to the fact that the structural integrity of the tree has been comprised and will pose a hazard to the public.
Tree #2 is scheduled to be removed Friday, June 15. There are plans to designate a landscape area at that location to give the opportunity for planting more trees and/ or plants at a later date.
From the arborist’s report:
“During the removal of the asphalt sidewalk and curb around Tree # 1, a minimal amount of small feeder roots were exposed. During the excavation down to sub-grade for the curb, many small feeder roots were exposed and severed. During the excavation down to sub-grade for the sidewalk only one tree root that was less than 1 inch in diameter was severed and a minimal amount of small feeder roots were severed. No large anchor roots were exposed.
During the removal of the asphalt sidewalk and curb around Tree # 2 a large quantity of small feeder roots were exposed. During the excavation down to sub-grade for the curb, a number of large structural roots were exposed and needed to be severed to allow room for the installation of the new curb.
During the removal of the asphalt sidewalk and curb around Tree # 3, a minimal amount of small feeder roots were exposed. During the excavation down to sub-grade for the curb and sidewalk, only a few small feeder roots were exposed and severed. No large anchor roots were exposed.
Due to the significant loss of feeder roots and the severing of a significant amount of very large structural roots during the excavation activities, it is recommended that Tree # 2 be removed. The cutting of the large roots may impact the structural integrity of the tree and the cut has opened up a wound across a large surface area of the tree root. It is highly likely that the wound will open the tree to infection and disease and the potential for the tree to recover is slim. In order to avoid the inevitable risk of tree failure causing damage to infrastructure or pedestrians, the removal of this tree is recommended.
The impacts to Tree # 1 and Tree # 3 due to the excavation activities to sub-grade were minor. As such, these two trees are not recommended for removal and their survival is fully expected.”
