The tree is surrounded by a rockery that creates a raised bed approximately 8-10' in diameter with asphalt pavement all around the planting bed. Western hemlock is a shallow rooted species, intolerant of drought, and prone to root disease. This tree has dropped a dozen or so branches in the recent past, one of which totaled a resident's vehicle. The branch drop is the result of drought stress and limited soil volume created by the relatively small planting bed and amplified by the reflective heat from the volume of asphalt and proximity to the building. The drought damage has accumulated over several years and has degraded the already limited root system. There is little to no new growth and shoot and tip dieback. Tree is declining due to the poor growing conditions and lack of available water. Recommendations: Future branch breakage is probable and will have a significant consequence. Overall risk is high. To prevent future damage and to mitigate risk the tree should be removed as soon as practical. Unfortunately, pruning is not a viable option as the tree is in a state of decline. The removal of the tree will not adversely affect the twelve remaining significant trees. Replacement requirements to be determined by city review.
