All trees are identified with numbered metal Arborist tags with green survey tape. Tree # 39 is on the adjacent property to the east but the radial drip line extends more than 20 feet onto the above parcel and will need to be protected if any further excavation occurs unless the property owner agrees for removal. Tree # 40 and # 41 are native trees to this region. Trees # 42 - 48 are not native to this area. Tree # 48 is considered an invasive tree species. `Radial drip line Deodar Cedar Western Red Cedar Dogwood .Japanese Maple Stewartia Magnolia Leyland cypress Ailanthus Cedrus deodara Thuja plicata Cornus nuttali Acer palmatum Stewartia pseudocamellia Magnolia Chamecyparis leylandii Ailanthus altissma TREE SURVEY No. Species DBH Ht.

The trees are numbered (see site plan). Signage should be posted indicating the tree protection zone outside the drip line (Outer Root Zone) .The trunk to the drip line is also referred to as the (Inner Root Zone) Fencing should be provided at no closer to the trunk than the drip line to prevent soil compaction by unnecessary foot traffic or construction machine activity. Any excavation within the Inner Root Zone is to should be performed by hand_ The fence should be 4- 6 feet high metal fencing. The fence posts should be located as not to damage any large anchor roots. The addition of 6 inches of bark mulch may be needed in some areas to prevent compaction. Soil compaction damages surface roots making them unable to absorb water and air normally. No building materials should be stored under the trees. The trenchless method for installing underground utilities should be used when possible as opposed to open ditch excavation to prevent and minimize damage to tree roots. Pruning may be needed to prevent any accidental damage to some of the lower branches. Any pruning should be performed by an experienced professional.
