Please refer to the photo documentation and additional materials (appendices A and B) when reading this report. An inventory of the large trees in the area of planned development was performed. A total of 66 trees were inventoried, with a total of 1397 diameter inches. There were eleven species recorded in the inventory. In the inventory 31 of the 66 trees received a condition rating of 4 (poor with serious problems). This indicates that 47% of these trees have serious structural problems and would not be good candidates for preservation. Many of the trees inventoried in this area could potentially pose a hazard to passerbys on 136th, the Monon and to the general public and therefore should be removed whether or not the development takes place. There were ten trees inventoried that were measured at 36" diameter at breast height (dbh) or greater. Six of these trees should be removed because of serious structural defects. As always, any trees that are preserved should be properly managed prior to clearing or construction including early fertilization, pruning and crown cleaning to reduce risk and liability. Trees should also be protected during all phases of development and construction to maximize their chances of survival. Please contact us if there are any questions about this work. We appreciate this opportunity to work with you. /~-(' 1; '1 ~v::>1. ff/~ Patrick Grecu, Natural Resource Specialist Indiana Accredited Horticulturalist # 1418 Judson R.

To inventory the mature trees located in the future construction area. 2. Determine which trees require a further structural analysis. 3. Perform structural analysis and visual tree assessments of the potentially hazardous trees in the planned construction area. Limitations Inspections were conducted March 22 and 23, 2006 with a covering of snow on the ground. Therefore, the findings in this report are limited by the time frame and present field conditions. Methodology All areas in the scope of work were inspected on foot. Tallies of the tree species were taken by species and size. The International Society of Arboriculture Tree Hazard Evaluation Form was used in the visual tree assessment of selected trees on the property. This protocol is exceptional for gathering data concerning a specific tree. The lane & Branch Threshold of Tolerance was then used to determine a risk rating for individual trees. This lane & Branch Threshold of Tolerance is part of the Tree Risk Advisory program for which Vine & Branch, Inc. has been awarded National Safety Awards by the Tree Care Industry Association (TelA) in 2003, 2004, and 2005. The lane & Branch Threshold of Tolerance is: Risk Rating . 1-5 - Tree presents limited risk under normal conditions. . 6-9 - Tree has structural problems and should be monitored. A routine inspection is recommended. . 10-12 - Tree or target should be removed. Other means of hazard abatement may be possible but must be used with extreme caution. Observations An inventory of the large trees in the area of planned development was performed. A total of 66 trees were inventoried, with a total of 1397 diameter inches. There were eleven species recorded in the inventory. Black walnut (Juglans nigra) comprises 33% of the total trees counted, and ash (Fraxinus sp.) accounting for 29%. Sycamore (Platanus occidentalis) and black cherry (Prunus serotina) each comprise 9%. Vine & Branch, Inc. Judson R.

In the inventory 31 of the 66 trees received a condition rating of 4 (poor with serious problems). This indicates that 47% of these trees have serious structural problems and would not be good candidates for preservation. Several of these trees could benefit from cabling or bracing to provide support to the potentially hazardous or weak part of the tree. Proper pruning would greatly benefit these trees, especially those trees where the potentially hazardous portion of the tree could be removed or reduced. Vine & Branch, Inc. Judson R. Scott, ReA #392 317.846.1424 Drees HomesNillage Green PJG 3.24.2006 Page 6 of 24 ;'" Ash accounts for a large percentage of the trees on the property, with 29% (19 of 66) of the trees in the inventory being ash. This represents a large portion of the population on the property. The future of ash trees remains uncertain with the discovery of the emerald ash borer in Hamilton and Marion counties. If the borer was to infest the area a large percentage of the total tree population would be lost. There were ten trees inventoried that were measured at 36" dbh or greater. Six of these trees should be removed because of serious structural defects. . The large American beech (# 17) south of the existing home has major structural problems resulting from decay and should be removed. . The chinkapin oak (#28) in the lawn area west of the home- has serious structural defects. . The black walnut (#31) in the lawn area west of the home both has serious decay that has compromised the structural integrity of the tree. . A large black willow (#50) is another tree that should be removed because of major decay, previous failure, and fungal fruiting bodies present. . A mature sugar maple (#60) located near the 136th street has a large cavity at the limb junction that compromises the structural integrity, and due to its location near the road it will either have to be cabled or removed to reduce the potential hazard. . The large sycamore (#64) has a major cavity that has developed at the root flare as well as a cavity in the trunk. This tree needs removed immediately. . The inventoried trees numbered 1, 5, 10, and 15-22 all pose a potential risk and are recommended for removal. There are two sycamores located east of the main drive (#6, #9) that show only minor problems and could be worthy of preserving. Another large sycamore in the southwest corner of the property (#65) only shows minor problems and is a nice tree worthy of preservation. A very large ash (#66) is located along the south property line that may require further inspection of the decay and deadwood that is present in the trunk and scaffold limbs. Many of the young evergreens along 136th street could possibly be preserved for the future development by transplanted them to a different area on the property. These trees would be an asset to the future residents because of the visual barrier and privacy that they would provide. Tree preservation is important to the community and the area wildlife, but it must be recognized that not every tree can be saved, especially those that could potentially pose a hazard to people. For those trees that are to be saved proper care will help maximize the long-term health of the trees and to minimize potential risks. Reasons for a Visual Tree Assessment Trees should be inspected help to reduce the potential for harm. To understand the need for a visual tree assessment you should be aware that in 1991, the Supreme Court of the State of Indiana upheld a lower court decision that a property owner was guilty of Vine & Branch. Inc. Judson R. Scott. ReA #392 317.846.1424 Drees HomesNillage Green PJG 3.24.2006 Page 7 of 24 'l negligence for leaving a dead tree on his property which eventually fell across a nearby highway and injured the driver of a passing car. The property owner had appealed a lower court decision and the Indiana Supreme Court upheld this earlier decision saying that the "possessor of land in an urban area is subject to liability to persons using a public highway for physical harm resulting from his failure to exercise reasonable care to prevent an unreasonable risk of harm arising from the condition of trees on the land near the highway." The Supreme Court also determined that it was the landowner's "duty...to perform periodic inspections to be sure that the premises do not endanger those using the highway." This ruling means that property owners are at risk of very costly negligence lawsuits for any harm resulting from trees falling into or across a highway or road. It also determined that property owners should perform periodic inspections of their trees to ensure there is no potential for risk. Vine & Branch, Inc. does not intend to provide legal opinion proper legal opinion should be sought from your attorney. Vine & Branch does have a concern that this definition of negligence has set a precedent for Arboriculturallaw which could be used to pertain to a tree such as yours. First and foremost no one wants a tree that could cause harm and secondly, the property owner's do not want to be exposed to negligence lawsuits. Vine & Branch, Inc. is also concerned by the general lack of understanding of how decay works in trees. A large tree with green leaves is not always a healthy one. Attached please find a brief discussion of decay that should be understood when determining the condition of a tree. Discussion of Decay There are many types of decay that can infect trees. Some attack the root system, while others attack the heartwood or sapwood. Decay is generally caused by a fungus that enters a tree through a stub, wound, or crack and weakens the woody tissue. Even though a tree may appear to be healthy, it may in fact have decay on the inside. Some signs of more serious decay are hollows and the presence of fungus growths such as conks (fruiting bodies of fungi). When wounded, trees are structurally unable to heal as humans and animals do. Because disease and decay can enter a tree through wounds, trees must be able to block the spread of decay. They do this by a process called Compartmentalization of Decay in Trees (CODIT). Once wounded, trees put up chemical and physical barriers in all directions to block the spread of disease. This CODIT process takes great amounts of energy from the tree. Trees are capable of compartmentalizing small wounds quickly while large wounds are much more difficult and take a lot longer, so decay is more likely to enter into these wounds. Trees are consequently weakened due to the amount of energy required to try to wall off the decay. Decay can structurally weaken trees, which may lesson their ability to support their own weight, putting people and property at risk. Vine & Branch, Inc. Judson R. Scott, ReA #392 317.846.1424 Drees HomesNillage Green PJG 3.24.2006 Page 8 of 24 .> . Visual Tree Assessment Procedure To assess the tree a nationally recognized protocol was used with the results being evaluated against the Wne & Branch Threshold for Tolerance. 1. First the tree was evaluated using the International Society of Arboriculture Tree Hazard Evaluation Form. This protocol is exceptional for gathering data concerning a specific tree. Part of this protocol is the use of a hazard rating. 2. To arrive at the hazard rating the following information is evaluated. · Failure potential (4 points) . 1- low . 2- medium . 3- high . 4- severe . The size of the defective part (4 points) . 1- most likely failure less than six inches . 2- most likely failure 6-18 inches . 3- most likely failure 18-30 inches . 4- most likely failure greater than 30 inches . Target rating (4 points) . 1- occasional . 2- intermittent . 3- frequent use . 4- constant use The hazard rating = Failure potential + size of part + target rating. 3. The final evaluation is to match the hazard rating against the Wne & Branch Threshold of Tolerance. This threshold has been developed through years of observing trees and uses the Risk Rating to set thresholds for tree retention. The Wne & Branch Threshold of Tolerance is: Risk Rating · 1-5 - Tree presents limited risk under normal conditions. . 6-9 - Tree has structural problems and should be monitored. A routine inspection is recommended. . 10-12 - Tree or target should be removed. Other means of hazard abatement may be possible but must be used with extreme caution. It should be noted that trees are living things abiding in harmony with nature. There are many circumstances that may arise that will cause a tree to fail. Not all of these circumstances can be foreseen. The only way to remove all potential for risk involving trees is to remove all the trees. This procedure is Vine & Branch, Inc. Judson R. Scott, ReA #392 317.846.1424 Drees HomesNillage Green PJG 3.24.2006 Page 9 of 24 .... not the goal or intention. The use of the visual tree assessment process is an attempt to provide useful information concerning trees and their risk potentials. This report is in no means a guarantee that a tree will or will not fail. Conclusion An inventory of the large trees in the area of planned development was performed. A total of 66 trees were inventoried, with a total of 1397 diameter inches. There were eleven species recorded in the inventory. Black walnut (Juglans nigra) comprises 33% of the total trees counted, and ash (Fraxinus sp.) accounting for 29%. Sycamore (Platanus occidentalis) and black cherry (Prunus serotina) each comprise 9%. In the inventory 31 of the 66 trees received a condition rating of 4 (poor with serious problems). This indicates that 47% of these trees have serious structural problems and would not be good candidates for preservation. Many of the trees inventoried in this area could potentially pose a hazard to passerbys on 136th, the Monon and to the general public and therefore should be removed whether or not the development takes place. There were ten trees inventoried that were measured at 36" dbh or greater. Six of these trees should be removed because of serious structural defects. Ash accounts for a large percentage of the trees on the property, with 29% (19 of 66) of the trees in the inventory being ash. The future of ash trees remains uncertain with the discovery of the emerald ash borer in Hamilton and Marion counties. If the borer was to infest the area a large percentage of the total tree population would be lost.

This feeding damages the sap wood of tree as the pest makes its feeding tubes. o Larva- over winters in the tree to emerge in May and June starting the cycle over. Vine & Branch, Inc. Judson R. Scott, ReA #392 317.846.1424 Drees HomesNillage Green PJG 3.24.2006 Page 22 of 24 Recommended Treatment Strategies First and foremost · Sound tree care will help Ash trees in general o Water- all trees need -1 inch of water per week. Especially June-September and right before going into winter. o Fertilize- A good granular fertilization or a professionally performed liquid ground injection once per year. o Tree preservation during construction- Take care when building around ash trees to do as little damage to the roots, trunk and crown as possible as Ash trees are not tolerant of construction damage. o General Care- Take care to keep the lawn mower and string trimmer away from the trunk of the tree. A light layer of mulch can protect the trunk from mechanical damage. · Realize that a weakened tree is a magnet for borers. o General Pruning- Remove dead and dying limbs from your mature trees. Cable trees with weak limb junctions. · Burn up your firewood every winter o Do not over-summer your left over wood. Especially Ash which is white wooded firewood. Don't be cheap buy more next year. o Do not transport wood to your campsite, lake house etc. Buy it in the county you are going to visit and leave leftovers there. If the ash borer is found in your area · Spray small trees with Tempo, Decathlon, Scimitar in early May and then 30 days later. · Larger trees may be treated with Imidicloprid products like Merit and Advanced Multi Insect Killer Concentrate. Check the label to make sure it is labeled for EAB. o Apply to the root zone of the trees in May and June or possibly in August and then again in May of the next year. o Always follow the manufacturer's directions. I.E. Do not over treat! · Larger trees may also warrant professional treatments with Arborject, Mauget or Koritz. · When in doubt call an expert who is a Certified or Registered Consulting Arborist. Removal Strategies · Remove small ash and replant with more appropriate species such as o Ginkgo 0 Tulip and others o Oak species o Maple species Vine & Branch, Inc. Judson R.
