Case Study: City of Kent, WA preserves a historic cedar tree with Davey Resource Group

City of Kent, WA preserves historic cedar with Davey in a 13-point risk assessment

The City of Kent, WA contracted Davey Resource Group (DRG) to perform a Level 3 tree risk assessment on a historic Deodar cedar in a public park. The tree had a noticeable lean and visible decay, posing a potential safety hazard to nearby roads and parked cars, which led to an initial high-risk rating from a visual inspection.

Davey conducted detailed resistance drilling at 13 points on the tree to assess wood strength and decay. Their analysis determined the tree had a low overall risk of trunk failure and was stable for the foreseeable future. DRG's solution provided specific recommendations for annual inspections and park modifications to mitigate risk and preserve the historic tree while improving its growing conditions.
