T1 Acer Pseudoplatanus, insufficient rooting area with a poor quality soil substrate contributing to a reduced overall lifespan coupled with a decreased ability to withstand biotic and abiotic factors. T1 Shows an unfavourable safety of 1.29, accepted calculated safety factor is 1.5. To increase the Safety factor to the 1.5 will require a reduction of a minimum of 2m (8% reduction in height), however with the previously passed cyclical lateral reduction to ensure 1.5m of clearance from the building there is the high likelihood that the combined reduced canopy area will severly compromise the trees health. T2 Acer Pseudoplatanus, insufficient rooting area with a poor quality soil substrate contributing to a reduced overall lifespan coupled with a decreased ability to withstand biotic and abiotic factors. T2 Shows an unfavourable safety of 0.9, accepted calculated safety factor is 1.5. The level of height reduction required to increase the safety factor to 1.5 would require a 4m height reduction, resulting in a significant loss of photosynthetic area and would compromise the tree's health severely. T002 has a non-tolerable risk level when utilising The VALID methodology of Tree risk/benefit and a Tolerable by Agreement risk level if using QTRA. As we cannot impart an "agreement" with passing vehicles or pedestrians this risk level must be downgraded to "risk will not ordinarily be tolerable".
