Box 7133 [LISPS Address] • 0229 Continental Court, Breckenridge, Colorado 80424 P.970.453 -9154 • info0acutaboveforestrv.com To whom it may concern, I was contracted by the general contractor (RA Nelson) and the owner (Zekelman) to complete a tree preservation plan to assist in the care for all trees on site during the construction phase of the new construction project at 463 Beaver Dam Rd. While completing my evaluation of the trees to remain, three trees are of concern. They are currently flagged with orange flagging. One is a large spruce on the Zekelman /Strong border to the East, one is the large double stem spruce on the Jordan's property to the West and the last one is just north of the property line near the pond and Jacuzzi. The trees are within the area of disturbance and there root systems will be greatly affected by construction related traffic and disturbances. Two out of the three trees are already stressed and the amount of construction damage they will encounter will most likely send them into irreversible decline. The tree located on the Strong property line has excavation planned right up near the root system and it will have buttressing roots damaged in the process. Secondly, I have been monitoring the tree on the Jordan's property for the Ransburg's as it has always been a concern due to its forked leaders. It has not improved in crown health and will most likely thin out completely in the coming years. Lastly the spruce just north of the property line has significant scale damage and is defoliating rapidly. We will be starting a pest program for the Zekelman's but the scale has already taken hold. Adding stress to the tree will most likely make the tree even weaker and more susceptible to scale. While it is known that construction around trees can lead to decline and death, it is difficult to know the different kinds of injury. The decline may not be noticeable until long after the problem has begun below ground. Insufficient rooting space, severed roots, poor drainage, compaction, and an inability to take up nutrients can contribute to a weakened root system and decline of the tree. As a result, these stressed trees are more susceptible to infestations by diseases and insects. The survival of urban trees depends on the health of their roots as well. Roots supply water and nutrients to the shoots, and get back sugar and other compounds they need to live. Roots also store food, synthesize hormones, and provide structural support. Research has shown that tree roots can travel a distance away from the trunk that is over 2%2 times the height of the tree, and more than 85% of root growth occurs within 18 inches (0.5 m) of the soil surface. Concerns When someone or something cuts the roots of trees to stop them from growing, it causes root injury and threatens the life of the tree. Through a variety of injuries caused by construction, roots can sustain extensive damage: when large buttress roots are severed close to the trunk, the tree loses substantial support and can become prone to windfall, cutting the roots that supply water makes the tree vulnerable to drought and also to pests that attack water - stressed trees, covering root injuries hides the extent of the damage. This creates an especially dangerous situation, since a casual examination can easily overlook root problems, roots must grow to take up many nutrients and when the soil is compacted, roots are unable to penetrate it, roots must be able to breathe to use the food they get from the leaves, tree roots are subject to frequent wounding by freezing and thawing soil particles around the roots, wet and dry cycles will also damage fine roots, as will burrowing animals, healthy roots and sturdy trees are necessary for the safety of workers in the trees. Page 11 According to the approved plan and staking on site the area of disturbance is too close to the trunk of these two trees and I am recommending removal. Please accept this letter as a request to remove the two trees we believe we will not be able to protect with proper root pruning, watering, protection and pest control during the new construction.

Nelson requested that Ceres Plus prepare a Tree Preservation Plan for the Zekelman Residence located at 463 Beaver Dam Road Vail, Colorado. I visited the site on April 7 and again on May 6, 2014to collect tree condition data. Assignment and Purpose The purpose of this plan is to provide tree preservation and management guidelines for the engineers, architects, contractors and the property owners. The guidelines will address tree preservation measures to retain healthy trees around the redevelopment. The goals of the plan are: 1. Minimize damage to the residual trees. 2. Insure residual trees will maintain quality and continue as assets to the landscape well into the future. 3. Identify trees that will not continue to be an asset to the site or will become a liability and recommend treatments. 4. Minimize the creation of hazard trees during the construction process. Scope of Redevelopment Project The reconstruction project will involve the demolition of the existing house and the construction of a new 12,000 ft2 duplex. The construction will include Tree removal, excavation, installation of utilities a water feature, landscape and hardscape. The driveway will be removed and realigned to accommodate the new duplex. The construction will require the movement of large and small equipment and material storage onsite. Present Tree and Site Condition The site is located 463/473 Beaver Dam Road in Vail, Colorado The property is two single - family parcels combined to create a .5 acre duplex property. The lot is bound by developed homesites to the east and west. Town of Vail property including Gore Creek delineate the property to the north. All utilities are installed underground. The current structure was built in 1988. All trees greater than 3.0" in diameter are identified on the site map. Each tree that is outside of the building footprint but inside of the disturbance area was inventoried and assigned an identification number. The trees are marked with numbered, flags. Zekelman Res 5/12/2014 Tree Preservation Plan 2 [Type text] Colorado spruce (Picea pungens), lodgepole pine (Pinus contorta), Bristlecone pine (Pinus aristata) and aspen (Populus tremuloides) are the only tree species remaining on the site. Trees on the site vary in height from approximately 35 to 85 feet. Tree diameters range from 3.0 inches to 21 inches. Tree diameters are measured at 4.5' above the ground (diameter standard height). Crown radius, the distance from the bole of the tree to the edge of the branches, a.k.a. the dripline, varies from 4 -feet to -feet. The dripline is an indicator of the absorbing root system. Although roots typically extend far beyond the dripline, a high concentration of absorbing roots is typically present between the dripline and the trunk. 1 Crown ratios vary from a high of 90% to a low of 20 %. Crown ratio is an important indicator to tree health and vigor. A low crown ratio means the tree has less green foliage to perform produce food. Generally, we can assume the less food production, the weaker the plant and the less likely it is to survive the stress of construction. The spruce trees on the site have high crown ratios as expected in healthy, high value trees. Total Height = 80 feet Live Crown = 50 feet Live Crown Ratio = 50 feet = 0.625 00 feet The soils around the site vary from highly disturbed and compacted to moderately disturbed. Areas immediately around the house the soil is heavily compacted at least in the top plates. The soils under the trees behind appear to be moderately compacted. A summary of the tree characteristics and condition inventory can be seen in Tables 1 U. Zekelman Res 5/12/2014 Tree Preservation Plan 3 [Type text] Table 1 Testing and Analysis I collected condition information using a variation of the Colorado Tree Coalition Condition Reference as a guide. This procedure involves inspecting and evaluating eight health and /or structural components on each tree. Each component is given a rating between 0 (dead) to 4 (no apparent damage).

The indirect effects include changes in water from grade adjustments, chemicals leaching into the soil and changes in local wind patterns due to lot clearing. These changes usually have minor impacts or can be mitigated to maintain a healthy tree for the long term. Direct impacts are those activities that invade the critical root zone the crown, the trunk or require the tree to be removed. Four large spruce trees plus several smaller aspen, spruce and pine will be removed to accommodate the construction activities per the construction plan. Two additional spruce trees are recommended for removal due to expected direct impacts caused by construction. Tree condition, age and species all affect how well a tree will stand up to construction stress. Trees that are already in poor health from disease, insect damage, soil compaction, nutrient deficiencies, overcrowding or being overtopped are at a serious disadvantage when it comes to surviving construction stress. Young trees and trees in better health and condition are generally adaptable and have a better chance at surviving the environmental changes that occur during construction. Trees live on an energy cycle that produces a surplus of energy during the summer months and a deficit in the spring during bud break. Young and middle aged trees in the growth and structural stage generally produce an adequate amount of energy to grow and provide defenses against insects, disease and environmental stresses. At least for one or two growing seasons assuming the stresses and damages are not too severe. As trees reach the mature and overmature stages of their lives, they are only producing enough energy to break the buds in the following growing season. Any root loss causing a reduction in stored energy or absorption capabilities will likely result in rapid decline and eventual death for the tree. Tree species respond differently to construction impacts. Colorado spruce trees in that they are moderately tolerant of root loss and somewhat tolerant of saturated soils but soil compaction will cause a slow death to roots. Aspen trees tend to be tolerant of root loss but will react poorly to saturated soils. Therefore any activity within the tree protection zone should be avoided, If encroachment is necessary all operations should be closely monitored. A particular problem with root damage is that its effects may take many years to surface and the results may be in the form of catastrophic tree failure due to root and stem rot or poorly developed root systems.

Typically, the healthier the tree, the more likely it is to remain a productive, contributing part of the landscape for many years after the project is completed. The best management approach is to bring the trees to the best possible health and condition prior to starting the construction project. This can be done by insuring adequate soil moisture for as long as possible prior to construction, testing the soil and applying fertilizer if necessary, inoculating the soil with mycorrhizae fungi and root stimulating fertilizer. In some cases thinning to reduce competition or pruning to improve tree architecture are the best management practices to improve health Mycorrhizae is a naturally occurring fungal relationship between tree roots and the soil. This relationship is common in undisturbed forest soils but, soil that has been "urbanized " through development, pedestrian traffic and other human disturbances often lacks this relationship. Mycorrhizae literally means fungus root. The roots and fungi form a symbiotic relationship that provides a secondary and very expansive root system for the host tree. The mycorrhizae relationship can multiply a tree's absorbing capacity from 10 to 1000 times the capabilities of non mycorrhizal trees. Studies have demonstrated a well colonized mycorrhizal root system is more tolerant of drought, soil Zekelman Res 5/12/2014 Tree Preservation Plan 8 [Type text] salinity, soil pathogens, parasitic nematodes and chemical imbalances in the soil. Mycorrhizal filaments produce humic compounds and organic "glues" that bind soils into aggregates and improve soil porosity. Soil porosity and soil structure positively influence the growth of trees by promoting aeration, water movement into soil, and root growth that more closely mimic the soil condition in the natural forest setting. The second concern is to identify, protect and treat the critical root zone (crz) throughout the construction process. To protect the crz, delineate it with fencing and install a 4 -inch layer of chips on top of the existing soil (See specifications section). Unfortunately, construction space constraints do not always allow protection of the recommended crz (See table 4 for the desired tree protection zone size). In these cases, individual prescriptions are prepared for the trees to address the problems created by disturbing the root zone. Specifications for Tree Preservation Mitigation and Remediation Guidelines Fertilizing 1. Deep root fertilize all spruce and aspen trees to be preserved. 2. Treat with a root stimulating fertilizer. Zekelman Res 5/12/2014 Tree Preservation Plan 9 General All remaining spruce trees shall be treated for pine needle scale in early summer. All remaining Guidelines Trees outside of the disturbance envelop should be inoculated with mycorrhizae fungi and treated with a root stimulating fertilizer and soil enhancements. Unless otherwise specified, the critical root zone (or as much as possible) shall be fenced with construction fencing. The fenced area shall be covered with a 4" layer of tree chips. Any excavation inside of the CRZ shall be supervised by a certified arborist. Any roots greater than 1/2 inch in diameter shall be pruned with a sharp tool and documented. Any branches that may interfere with construction should be pruned by an arborist prior to construction. "Claw hammer pruning" by the construction crew is prohibited. In addition to the general guidelines the following trees will need additional mitigation measures. Inspect soil moisture and apply supplemental water as needed. Aspen trees should be fertilized and treated for aphids and mites to minimize insect and nutrient caused stress. Supplemental water will be necessary for trees since the irrigation system will be shut off during construction. Water can be provided with a temporary drip system or hand watering. Soil Treat compacted soil in root zone by aerating soil with air spade. Excavate entire area 4 feet out Compaction from root collar. Mix compost, organic fertilizer and mycorrhizae in aerated zone. Fencing Fence the west side of trees to be retained on east side of house to protect critical root zone. When recommended areas cannot be protected due to access issues area outside of fencing shall be protected with geotextile plywood and a six inch chip layer to minimize soil compaction and root damage. Mitigation and Remediation Guidelines Fertilizing 1. Deep root fertilize all spruce and aspen trees to be preserved. 2. Treat with a root stimulating fertilizer. Zekelman Res 5/12/2014 Tree Preservation Plan 9 [Type text] 3. Fertilization will be performed in a radial pattern with the feeder needle being inserted 8 -10" below the soil surface. Insertions will be made at 18" intervals on the edge of the drip line. 4. The first feeding shall include an inoculation with mycorrhizae fungi. Fencing 1. Fence all trees to be retained to completely enclose the tree protection zone, as indicated in table 3. Fencing shall be installed and reinforced with silt fencing to protect the critical root zone around all trees. Fences will remain until construction is completed. 2. Construction traffic and material storage must remain outside of the fenced areas at all times. Pruning 1. Prune branches to provide adequate clearance for scaffolding and construction crew. 2. Pruning shall be performed or supervised by a certified arborist. The tree service must provide proof of insurance for liability and workers compensation. 3. All pruning will be within the Tree Pruning Guidelines (International Society of Arboriculture) and adhere to American National Standard for Tree Care Operations (ANSI A300) 4. Any additional tree pruning needed for clearance will be performed by an arborist, and not by construction personnel. Root Pruning 1. All encountered roots over 1/2 inch in diameter will be cut off with a sharp tool. 2. Root will be pruned with a sharp shovel, saw or by -pass pruning tool. 3. Root pruning shall be performed or supervised by a certified arborist. 4. Roots should be exposed by hand, with an air spade or with a small excavator. Any digging to expose roots shall be done parallel to the tree to avoid breaking or tearing roots. Soil Compaction Mitigation and Remediation 1. After construction is complete but prior to finish grade landscaping the compacted areas shall be remediated using an airspade per the directions in the Specifications for Tree Preservation guideline section. Zekelman Res 5/12/2014 Tree Preservation Plan 10 [Type text] Supplemental Water 1. Supply supplemental water to spruce trees on east and west side of property using temporary drip system, soaker hose or netafin. In the heat of the summer apply 600 gallons every 5 -7 days to the spruce trees on the east side of the property. Provide 320 gallons every 5 -7 days to the spruce trees on the west side of the house. 2. Check soil moisture with a moisture meter or by digging a small hole approximately 8 inches deep squeeze the soil in the palm of your hand. If it is muddy, cut back on water supply by 25 %, it is so dry that it will not hold the shape of your hand increase the water by 25 %, if the soil maintains the shape of your hand but is not muddy the water is adequate. General 1. Any activity within the tree protection zone must be approved and monitored by the Consulting Arborist. 2. Any herbicides placed under paving materials must be safe for use around trees and labeled for that use. 3. Any grading, construction, demolition or other work that may encounter tree roots should be monitored by the Consulting Arborist. 4. Do not store or dump excess soil chemicals, debris equipment or other materials within the tree protection zone. 5. Install and maintain a 4 " -6" layer of mulch along the fence line west of trees. The mulch will help reduce soil compaction and moderate soil temperature. Insect Treatments 1. Treat all spruce and pine trees for pine needle scale insects (Chionaspis pinifo[iae). This treatment should be performed annually to reduce the population of scale insects on the tree and minimize damage to foliage. 2. If identified during the construction process, treat aspen trees for aspen scale (Diaspidiorus gigas) to reduce the population and minimize the potential for tree decline and loss. 3. Treat aspen trees for aphid and mites annually to reduce damage and stress caused by the insects. Monitoring Tree Health and Compliance Successful tree preservation programs start during the planning phase when critical design decisions are made. However, activities in the construction and post - Zekelman Res 5/12/2014 Tree Preservation Plan 11 [Type text] construction phases are critical to successful tree preservation. In other words, trees cannot be preserved during construction but they can be killed during construction. Monitoring tree health and compliance during construction helps ensure that the program and details specified in this Tree Preservation Plan are properly implemented. The monitoring phase of the plan is fourfold: 1) Maintain the integrity of the Tree Protection Zone, 2) Assist with field changes, 3) Continually evaluate tree health and injuries, and 4) Communicate with the Superintendent, Architect and Engineer. .

B) Non -woody roots that are infected by beneficial fungi are called mycorrhizae. Mycorrhizae are organs that facilitate the absorption of phosphorus and other soil elements as well as water. Mycorrhizae (sometimes written as mycorrhizae (singular) and mycorrhizae, (plural) are active for months to a year. They are organs on most trees. Pruning The selective removal of woody plant parts of any size using saws, pruners, clippers or other pruning tools. Roots (absorbing) Absorbing tree roots are organs that absorb free water and elements dissolved in it from the soil. Non -woody absorbing roots have very little lignin and no corky outer bark. Woody roots have lots of lignin and a corky outer bark. Non -woody roots do grow in winter in non - frozen soils, and may even grow in non - frozen soils below frozen soils. Also see root hairs and mycorrhizae which are associated with non -woody roots. Roots (woody) Woody tree roots are organs that support the tree mechanically, store energy reserves, transport free water and the substances dissolved in it and synthesis substances such as growth regulators, amino acids and vitamins that are essential for growth. They also hold water in the form of bound water. They also contain more lignin than non -woody roots.
