Rangeline Rd. Carmel, IN 46033 Re: T~e Villas at Morgan's Creek By: Judson R. Sea Registered Consulting Ar American Society of C and Jeffrey Maddox, Ecol ISA Certified Arborist #IN- December 14, 2004 e e Executive Summary This plan is based upon the Landscape plan dated 10-22-04. All trees to be preserved should have protective fencing installed before clearing and construction begins. The trees between lots 6,7, & 8 and between lots 9 & 10 seem to be at the most risk due to the proximity of the construction. Assianment Our assignment is to prepare a plan to preserve the trees before, during and after the development of The Villas at Morgan's Creek Subdivision. Specific concerns include: 1. Contributing to the success of this development by retaining as many trees as possible. 2. Provide specifications for the preservation of those trees. 3. Educating all contractors about the importance of the trees to the success. We are to advise the client, architect, landscape architect, builder and contractors on processes that may impact the trees within the constructi9n zone or nearby. Our goal is to prevent or lessen the impact of the construction to help preserve the trees. Tree Biolcay and Construction Imoacts 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. There tends to be less disturbance to individual trees 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, changes this and causes 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 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 quicldy. Large wounds, however, are much more difficult and take a lot longer. In fact, a trunk wound removing as little as 300/0 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 Corbier Traditions - Tree Preservation 14 December 2004 page 2 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, induding trunk decay, decline, and death. e inches of the original grade; with a . large majority of the fibrous roots within the first 6-8 inches of the soil (see Figure 11). e ........ ....,. I ! Figure 1 Besides mechanical and root damage, trees will also be exposed to environmental factors such as changes in water sources and exposure to sunlight. Sb"ess is created when trees need to acclimate to a new environment created by a change in anyone 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 t~ limit stress to the trees to be preserved. 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, induding: . Installation of fencing to protect the root zone. . Installation of signage for preservation zones. . Pre-consb"uction fertilization of key trees. . Root pruning during construction after roots are damaged. . Implementation of a watering program. . Site visits during the construction process. . Post-consb"uction 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. Corbier Traditions - Tree Preservation 14 December 2004 Page 3 e a ., Site or Tree Analvsis The development of The Villas at Morgan's Creek will take place on a 6.44 acre site located at 14309 Gray road, approximately 0.25 miles south of 146th street in Carmel, Indiana. Also known as, part of the NW 1/4 of Section 21, Township 18N, Range 4E, 2nd PM, Indiana. It is a former residence with a house, barn and several out-buildings located in the western end of the property. This western half is a mixture of scattered mature trees, a few fruit trees, and open lawn. A creek runs north-south through the property separating the property roughly into two halves. The eastern half of the property was cleared and has regenerated into scrubby trees and invasive shrubs. There are some remaining trees around the perimeter and along the creek. The property is more fully described in the "Woodland Analysis" report completed by Vine & Branch in October of this year (2004). Discussion This plan is based upon the Landscape plan dated 10-22-04. This plan is general and does not address individual trees. The management needs of individual trees can be added to this plan as the project develops and individual trees are selected. All trees to be preserved should have protective fencing installed before clearing and construction begins. 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. It is important to take into consideration each species when preparing a tree preservation plan. Some of the species are generally considered to have moderate to good tolerance of construction,.including the oak species (Quercusspp.), American elm (Ulmus americana), hawthorn (Crataegusspp.), and crabapple (Malusspp.). Their response depends mostly on how much soil compaction, root disturbance, and water stress they receive. American elms are considered to be tolerant of site disturbance, their pest problems put them at greater risk. Elm bark beetles, which carry Dutch elm disease, are attracted to stressed trees. Care must be taken to keep the stress on the elm trees down. Some species are much less tolerant and will need strict care, including sugar maple (Acer Saccharum), American beeth (Fagus grandifoha), black walnut (Juglans nigra), and black cherry Corbier Traditions - Tree Preservation 14 December 2004 Page 4 e e (prunus serotina). Special attention will need to be placed on each of these species. They will require adequate water and care to have a chance at survival. Sugar maple, American beech, and black walnut are considered intolerant of flll. The grade should not be raised around these trees. It is imperative to keep the original grade within the critical root zones of these trees. American beech, black walnut, and black cherry are aU intolerant of mechanical injury due to poor compartmentalization. When the specific trees are identified for this project, we will add more detail to this plan. At this stage, trees will be protected by the general rule of installing protective fendng at, or beyond, the dripline of any tree. The trees between lots 6, 7, & 8 and between lots 9 & 10 seem to be at the most risk due to the proximity of the construction. These trees should be fertilized before construction begins to - ,- increase their ability to cope with the stress of construction. Trees within the preservation zone shall be protected during construction and maintained after construction is finished. All trees should be properly fenced and everything kept out of the root zones to limit damage to the trunks and canopies. Specific recommendations indude: Before Construction: . The trees within the zone should 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. Durina Construction: . Any damage to trees shall be reported to the Consulting Arborist within 6 hours so that remedial action can be taken. Timeliness is critical to tree health. . No materials, spoil, washout water, waste or equipment, (especially conaete 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 inigation 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. Corbier Traditions - Tree Preservation 14 December 2004 Page 5 e e . 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. . 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 This plan is based upon the Landscape plan dated 10-22-04. All trees to be preserved should have protective fencing installed before clearing and construction begins. The trees between lots 6,7, & 8 and between lots 9 & 10 seem to be at the most risk due to the proximity of the construction. We commend Corbier Traditions for thinking of the immense positive impact trees have on the quality of life within the community and planning for their protection during construction. 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.
