The property at Village Green has many trees that, with the proper techniques, can be saved for future generations. The trees that surround the creek area are important for the health of the creek and for wildlife habitat. Planning for the preservation of these trees is the first step to ensuring their survival through the construction process. Protective fencing should be placed five feet outside of the canopy of each tree to keep all construction related activity outside of the root systems on these trees. Protecting the trees in groups will provide greater protection. An aerial photograph and a site plan are shown in Appendix A. Tree preservation is a group effort. To insure success, the preservation project needs the cooperation of all contractors involved. Everyone needs to understand the importance of the keeping all activity outside of the root zones of these trees. Following this tree preservation plan will maximum these tree's chances for survival and allow us all to benefit from them for years to come. We appreciate this opportunity to work with you. Please contact us with any questions about this work or any other services we can offer. Si gerely, f `` S ec7'T ++ `I Judson R.

To insure success, the preservation project needs the cooperation of all contractors involved. Everyone needs to understand the importance of the keeping compaction out of the root zones of these trees. Planning and implementing tree preservation plans before, during and after construction will reduce replacement costs and tree health maintenance. Following this tree preservation plan will assure maximum returns from the trees that remain. Assignment Our assignment is to prepare a plan to preserve the trees before, during and after the construction of the Frenzel .residence. Specific concerns include: 1. Tree preservation fencing installation 2. Tree preservation signage installation 3. Pre -construction meeting with builders for tree preservation 4. Site specific written Tree Preservation Plan 5. 10 site inspections during construction phase 6. Attend any necessary zoning meetings We are to advise the client, architect, landscape architect, builder and contractors on processes that may impact the trees within the construction zone or nearby. Our goal is to prevent or lessen the impact of the construction to help preserve the trees. (Discussion Only half of a tree is above the ground but, since the roots aren't seen, they are often overlooked. The roots are just as important as the branches and the leaves. The greatest damage during construction often comes from injury to the unseen root systems. Many construction processes require extensive amounts of excavation or soil compaction. Excavation within root zones removes both support roots and absorbing roots. The tree suffers decreased stability and water stress making the tree more likely to fail or fall. Soil compaction is also common. Soil compaction decreases the amount of air and water available to the roots, limits root growth, and can lead to decay, decline, and death. For structural stability, compaction is required for buildings, roads, footings, sidewalks, etc. Compaction is also caused by equipment moving over the ground and material storage. All soil compaction activities should be kept at least five feet beyond the dripline of all trees. This includes all grade changes. Vine & Branch, Inc. Drees Homes/Village Green TPP Judson R. Scott, RCA #392 3.28.2006 317.846.1424 Page 3 of 15 Tree Biology and Construction Impacts Construction often has a negative impact on trees. When changes are planned, we must plan tree preservation procedures to be performed before, during, and after construction to give the trees a better chance at survival. In wooded areas, trees live in harmony, protecting and supporting each other, where there tends to be less disturbance from environmental factors like wind, ice, and snow. The root systems of mature trees are shaded and protected. In mature landscapes, existing trees have been relatively undisturbed for many years providing them with a "wooded area" environment. Therefore, any construction procedures that come near the root system of any existing tree will cause stress. One common problem during construction is mechanical damage (physical injuries/wounds to the tree) to the trunks and limbs. When wounded, trees are structurally unable to heal as humans and animals do. As trees can not replace damaged tissue, they must wall off the area using a process called Compartmentalization of Decay in Trees (CODIT). Using this process, the damaged cells of Figure 1 trees put up chemical and physical barriers in all directions to block the spread of disease and decay after being wounded. Trees are capable of compartmentalizing small wounds quickly. Large wounds, however, are much more difficult and take a lot longer. In fact, a trunk wound removing as little as 30% of the bark may be fatal. The CODIT process also uses great amounts of energy. Trees are weakened due to the amount of energy required to try to compartmentalize the wound. Wounds are also an entrance for decay and disease to enter the tree. Decay structurally weakens trees, which may eventually be unable to support their own weight, putting people and property at risk. Protecting the trunk and limbs from damage is crucial. Another significant problem caused by construction is damage to the root systems of the trees. There is a classic misconception that roots are "as deep as the tree is tall". They are not! The root systems of most trees are very shallow. Roots generally grow within the first 12-18 inches of the original grade; with a large majority of the fibrous roots within the first 6-8 inches of the soil (see Figure 1). There are two major types of roots. The large woody roots most of us are familiar with that provide anchorage, storage, and conduction. Trees also have small, non -woody roots called feeder roots. These roots provide absorption, pulling water and nutrients from the soil, both of which are necessary for photosynthesis and respiration. In order for roots to grow, they need both moisture and oxygen. Roots can extend long distances from the trunk, often two to three times the radius of the dripline, depending on the environment and where oxygen and water are available. Changes in the root system of a tree can cause serious, long-term problems, including trunk decay, decline, and death. Besides mechanical and root damage, trees will also be exposed to environmental factors such as changes in water sources and exposure to sunlight. Stress is created when trees need to acclimate to a new environment created by a change in any one of these factors. During construction, many factors become a concern at the same time, making preservation planning very necessary. It is our goal to help the trees whenever possible. The procedures we will recommend are to limit stress to the trees to be preserved. Vine & Branch, Inc. Drees Homes/Village Green TPP Judson R. Scott, RCA #392 3.28.06 317.846.1424 Page 4 of 15 In protecting the trees from construction, our main focus will be shielding the critical zone of the root system from damage. There are various means of protecting the trees and their roots during the construction process, including: • Installation of fencing to protect the root zone. • Installation of signage for preservation zones. Pre -construction fertilization of key trees. ® Root pruning during construction after roots are damaged. • Implementation of a watering program. Site visits during the construction process. • Post -construction vertical mulching in areas of high soil compaction. ■ A post -construction planning for continued preservation efforts. Although there is no way to guarantee the trees will not die during or after the process, we should do our best to protect the trees and give them a fighting chance. Best Management Practices BMP's for inclusion on engineered drawin s: Before Construction: • The trees within the zone shall be fertilized before construction begins to increase their vigor. This will increase their ability to handle stress from construction. • All site contractors shall meet with the Consulting Arborist at the site prior to beginning work to review all work procedures, access and haul routes, and tree protection measures. • Tree protection fencing shall be installed at the dripline of the trees in the buffer zone and proper "Tree Preservation Zone" signs affixed. During Construction: • Any damage to trees shall be reported to the Consulting Arborist within b hours so that remedial action can be taken. Timeliness is critical to tree health. No materials, spoil, washout water, waste or equipment, (especially concrete equipment and tools) shall be deposited, stored, or parked within the tree protection zone (fenced area). • The Consulting Arborist should monitor any grading, construction, demolition, or other work that is expected to encounter tree roots. • Spoil from the building foundation shall not be placed within the tree protection zone, either temporarily or permanently. It is suggested that the spoil be placed in a space away from the trees. • The preserved trees shall be irrigated so that they will receive 1-1.5 inches of water per week during dry periods. • All underground utilities, downspouts or irrigation lines and landscape lighting shall be routed outside the tree protection zone. If utility lines must cross through the protection area, they shall be tunneled or bored under the tree. • There is to be no parking or equipment storage of any kind within the tree protective zone. Post Construction recommendations: • All trees should have a post -construction evaluation performed by a qualified arborist to determine any remedial actions necessary to maintain tree health. • Vertical mulching for any trees within 20 feet of construction activities, especially those with any compacted soils or altered drainages. Vine & Branch, Inc. Drees Homes/Village Green TPP Judson R. Scott, RCA #392 3.28.06 317.846.1424 Page 5 of 15 Regular mulching for any trees outside of the compacted areas that do not have regular leaf litter anymore. The mulch will give the trees optimal conditions for their roots to recover from the stress of construction. The Tree Preservation Specifications section has more explanation on each of the above concerns. Vine & Branch Fact Sheets on each subject are also available. Site visits by the Consulting Arborist are helpful in monitoring the above concerns. He can then advise as to any further procedures necessary to protect the tree. The site visits should be regular to increase the protection provided to the tree. Finally, the end of construction does not mean the end of tree preservation. The first five years following construction are critical in the health of the tree and present a window in which further care is to be undertaken. Tree preservation is an ongoing effort. Watering, fertilization and necessary pruning should be undertaken. Conclusion The property at Village Green has many trees that, with the proper techniques, can be saved for future generations. There are several large trees in the lawn area that is near the creek. The trees that surround the creek area are important for the health of the creek and for wildlife habitat. Planning for the preservation of these trees is the first step to ensuring their survival through the construction process. Protective fencing should be placed five feet outside of the canopy of each tree to keep all construction related activity outside of the root systems on these trees. Protecting the trees in groups will provide greater protection. An aerial photograph and a site plan are shown in Appendix A. Tree preservation is a group effort. To insure success, the preservation project needs the cooperation of all contractors involved. Everyone needs to understand the importance of the keeping compaction out of the root zones of these trees. We thank you for your cooperation and consideration in this project. Planning and implementing tree preservation plans before, during and after construction will reduce replacement and/or maintenance costs. Following this tree preservation plan will maximum these tree's chances for survival and allow us all to benefit from them for years to come. We should all feel pride as we watch these trees continue to thrive in their new environment. Vine & Branch appreciates this opportunity and looks forward to working with you in the future. I certify that all the statements of fact in this Tree Preservation Plan are true, complete and correct to the best of my knowledge and belief, and that they are made in good faith. Judson R.
