Each tree on site now sports numbered metal tags (20). 12 trees are slated for removal. 3 trees with DBH's below the required 8" are included on this list as we looked at every tree. These trees are not used in the computations for the "Tree Retention Worksheet" The International Society of Arboriculture Level 1 inspection method was used. All trees to be removed, to allow for the proposed development with numerous trees to be replanted. The trees that will remain are relatively young trees and should withstand the exposure clearing will create. The health of the trees is similar, again they are young trees to 40' in height with full if asymmetric crowns. No deadwood was found. These trees are a vigorous species will remain viable for many years. However, as the retained trees are all cottonwoods in the years to come they will pose increasingly elevated risk levels. The reasoning for this is, the species vigorous growth to 160' in height and relatively brittle wood. In advanced years, they are subject to summer limb drop endangering the parking and living spaces. Driplines were determined by visual observation of the existing tree limbs. It will be important to not disturb the root systems of the retained trees. This will start with stump grinding rather than pulling out of stumps for removals located in overlying dripiines. After that fencing, shall be installed at the outer limits of the dripline with signs stating that there is to be no excavation, parking, storing of materials or walking inside the protective fencing. There will be little to no adverse effects on trees of the abutting properties as they are already well spaced and away from site boundaries and trees. This isolation will leave the abutting tree roots untouched. The new building when complete will replace the wind screening lost from tree removals. Find listed the species, DBH measurements.
