I was asked by Mr. Simon Vuong, Planner, City of Cupertino, �.-�e� a peer ie th . report by Mr. Dave Muffly concerning the replacement of Lombardy poplar ees at the. nite . Loop Street, Cupertino, California. Observations I inspected the site on June 30, 2011. It is obvious that several of the Lombardy poplar (Populus italica `Nigra') trees have died or are in severe decline. Removal and replacement of those specimens requested is certainly warranted. The suggested replacement species, Platanus acerifolia `Columbia,' has shown to be a strong performer in this area, and is certainly an acceptable replacement species. Comments I have seen Lombardy poplar trees (Populus italica `Nigra') performing well in various parts of this valley. They commonly cause major infrastructure damage, without exception in my experience, where located near structures or hazdscape. I observed several Lombardy poplar specimens, which are in relatively good condition at this point and which are not requested for replacement, located near infrastructure in this landscape. I did not observe any infrastructure damage, but the trees are young and are fully expected to cause significant infrastructure damage in the near future. For this reason, I suggest that all of the Lombardy poplar trees located in planter beds at this site be included in a replacement plan. In addition to the decline and mortality of the Lombardy poplazs, there are a significant number of other trees, which are performing poorly in the planter beds of the parking lots on both sides of Infinite Loop. These numerous trees include the species: Platanus acerifolia ( it appears that many are the cultivar `Yarwood') and coast live oak (Quercus agrifolia). There may be other species, which I missed, in addition to these. These species typically perform well, if not exceptionally well, in this area. Also, it is very unusual, in my experience, for so many Lombardy poplaz specimens to perform so poorly in a small area, as observed here. This observation suggests that there are other causes for the decline at this site. Mr. Muffly did not discuss causes of decline specifically in his report. Nevertheless, I think it is likely that the Platanus acerifolia `Columbia' replacement specimens will not perform as hoped unless the primary causes are addressed. In recent years, I have observed similar decline of the landscape, trees in particular, at other corporate campus locations. At these locations, one of the primary causes of landscape decline is a result of poor drainage and severe soil compaction, especially of the sub-grade. Obviously I do not know what has occurred at this site, but at other locations, the soils at the time of construction in the entire parking areas were compacted to 90% to 95% Proctor Scale, which is engineering standard for roadway construction. After the formation of planter beds in this highly compacted soil, a thin layer of top soil is often added before trees and shrubs are planted. Although trenching for irrigation loosens the soil slightly, it is very inadequate for root development of trees. This is particularly problematic in areas where planter beds are very small or are very narrow. If trees of most species would be expected to perform well, larger areas for root development must be created. In areas of small or narrow planter bed spaces, structural soil Prepered by Michael L. Bench, Consulting Arborist June 30, 2011 (a formulated engineered soil) has shown to be an effective alternative without the reduction in parking. No doubt Mr. Muffly and Apple has considered this and possibly other alternatives. Respectfully submitted, � .� e.t__ Michael L.

That original report led to the removal of the dead trees, and also trees which were then in poor condition. This work has been permitted, and is now in process. But in the intervening several months, poplars that were in good or fair condition upon original report writing have now declined substantially, leaving us with more poplars in poor and fair condition. This report is an update to that earfier report. We are now requesting to remove ALL of the poplar trees, regardless of condition. When the report was originally written, it was early summer, and we didn't want to take out the best of the poplars during the heat of the summer. Now the trees are headed into dormancy, and this will be the ideal time to remove the remainder of the poplars, and have a fully uniform and beautiful set of London Plane trees for the entrance drive to Infinite Loop 1, all ready for the 2012 growing seasan. .

Fig. 1- Infrnite Loop main entry t� Apple Confidential - Do Not Distribute Date of Report: September 21, 2011 Page 1 Anac�ranis�n To have this particular species planted in such a prominent location in 2011 is something of an anachronism. Landscape professionals began phasing out this species in the 1960's and 1970's, and by the early 1990's, only a handful of "old school" practicing landscape architects were still utifizing this species. By chance, Apple hired one of the few remaining, and have been paying a serious cost since. P�c��u[a��� Lombardy poplars were popular because they grow in a strikingly upright manner, grow quickly providing welcome shade in hot climates, have attractive glossy foliage, create minimal debris, and offer good yellow fall color. They are a tree traditionally planted along irrigation ditches and canals, and natural watercourses, where their habit of growing large and destructive surFace roots doesn't pose any difficulties. Poplars are notoriously shallow rooted. Pra�[erns But when planted in the cities of California, problems became readily apparent. In urban places without copious, continuous water availability, poplars readily succumb to drought. And even if given precious irrigation water, if the poplars are planted near hardscape or infrastructure, major damage is virtuafly inevitable. For these reasons, poplars in general, and Lombardy poplars in particuiar, fell out of favor. This change was faster for landscape professionals more inc{ined to be scientific, and slower for those who clung to ideas of what works without assessing actual performance. �as� �raubfe A� ��p[e Many, if not all, of the poplars along the IL 1 aisle have been replaced once already, giving an unacceptable lifespan of 10 years or less. When the first set of replacements took place, replacement trees had to be procured from Southern California, because literally no nursery in the Bay Area could be found still stocking the trees. — — -- -- --- _, _ _-- — -- - ��. �;,� �` M r � M , M _ � . !

The Infinite Loop 1 parking lot suffered heavy damage from the first generation of poplar plantings along the main aisle, and this damage is being repeated with the replacement generation, as can be seen in Figure 2, where a root sprout off a poplar root actually pushed right through the asphalt. �.ep f �cecr�er�� S��a�e�g�r As outlined in the introduction, Apple Computer is now ready to remove ALL the remaining poplar trees, and fully implement the Replacement Strategy outlined in the earlier report. If these few poplars were to be retained, they would look awkward next spring. The coming months will be an ideal time to remove the remainder, and plant the replacement trees with optimal late fall timing, ensuring excellent tree establishment over the coming winter, and vigorous grov�h from a uniform set of London Plane trees next year. At this time, there are 7 poplars that remain in good condition, 4 in fair condition, 6 in poor condition, and 4 in very poor condition. We propose to remove all these remaining poplars, and replace with 'Columbia' London Plane to match the remainder of the planting. ���[a��n���f ��e�«� : � `� • „ ; - '.: � =�,- _ � R 0 � • � i � 0 S . :_ �� � �� . r �� �� �� � ,; � . / / ► / / / � / � { .; � . + ���:•:,s +„a, ��" �c"�� �-��. {,' . _ - i :. � . +e • ?i�s,]�r_�f"� �Tt.' ^�,. � � . �j i�� �j cF � � t � � • • ' �r ,„"„ ? �" �`� �, z' � • �• `,,, , "�r �t �, � � K'•.., * � x S�C�a" • . ,'� �.• ?�, , a'r '� ``� "` � � ',,� . r>�. � �1 - - : t ,• � sG� ` '� � � ^ . . ��t�.

They are also featured in the downtown Gilroy redevelopment, and are growing nicely. Santa Cr�z Exper�ence 'Columbia' is also used extensively in Santa Cruz, where I introduced it to the public by specifying it along Mission adjacent to a large public school. Within a decade, 'Columbia' has become the most planted tree in Santa Cruz, and is performing well in a{I but the harshest locatians. Replacerner�t Spec�es CF�a�ces What tree species will work well in this location? Native deciduous Valley Oak? Native evergreen Coast Live Oak? Chinese Elm? Fruitless Olives? Marina Madrone? Silver Linden? London Planetree a.k.a Sycamore? These are all readily-available options, all of which (with the exception of one) stand a good chance of succeeding and surviving for decades, perhaps many, with relatively little maintenance and supplemental water. The exception is Marina Madrone. These very pretty trees need excellent growing conditions, not the challenging conditions to be found along the main lobby to Infinite Loop 1. Native Oaks The native evergreen Coast Live Oak could be grown in this location, but it would create a dense, brooding, spiny-leaved, messy planting. Also, nursery stock performance with this species is notoriously inconsistent, especially in degraded soils such as we have here. It seems wise to save the Valley Oaks for places where they can grow large, with lots of room. Best Qf The Rest Among the rest, the 'Columbia' London Planetree is favored for fast growth deep non-invasive roots, beautiful bark, strong/low-maintenance structure, long lifespan, and is a tree which will create a proven effective and classic landscape architecture. They will also quickly make some precious shade for the large parking lot, at least on the Highway 280 side. They roughly resemble the poplars (big leaves, upright growth habit - they are distant relatives), so this will minimize any change to the aesthetic. Sp�ed Ar�d Str�ngth From personal experience, 4 feet of growth per year in the early years is very possible with wise water management. The shape of'Columbia' is nearly ideal from both an arborists and designers perspective - it generally grows with a continuous central leader, which is great for strength, and also gives the tree a very uniform, pyramidal shape when young. Apple Confidential - Do Not Distribute Date of Report: September 21, 2011 Page 5 Quick GanQp�r Having two double rows creates a particularly powertul effect, and the canopy closes over the pedestrian walkway in a very short time, just a few years. The trees may begin to provide a c{osed canopy over the roadway in as little as a decade if we are generous with the water in the early years, and plant with thought and care. Adapted TQ C�QSe Pla�tir�g London Planes are proven to perform well when closely planted. This can be seen in some of the older residential sections of Bay Area cities like Palo Alto and San Jose. The oldest Landon Planes in the Bay Area are still going after more than a century, without any sign of vigor loss. Longevity and Drought To�erance Those old London Planetrees throughout the Bay Area, some of them approaching 150 years old, show us in no uncertain terms the level of drought tolerance of the Planetree. As an arborist with more than 20 years of observing trees throughout the Bay Area, and a renowned eye for trees, I can say that I cannot recall seeing a mature London Plane die. I learned my trees during the severe California drought of 1988 through 1993. I watch many hundreds of trees die, but not London Planes. They are on the short list of trees commonly planted in California which are proven to tolerate the droughts of the last 150 years, a list mostly populated by oaks and eucalyptus. A Tree Of Extre�es They are, surprisingly, a species that both survives drought, and can also grow in standing water, as can be seen with century-plus old London Plane trees growing in a small lake in Golden Gate Park, San Francisco. Biologically, there is a reason that London Plane can survive in disparate places where few other trees can survive. All sycamore trees have the ability to transport oxygen from their leaves and upper surfaces to the roots, where the oxygen is needed for cellular respiration: i.e. oxygen is needed to process sugars to make the energy that allows the roots to grow and live. The Impartance af Oxygen Most trees have to get their root oxygen directly from the soil. And because many soils, especially clay soils, don't allow air to penetrate very deeply into the soil, tree roots are often found surprisingly close to the surface, often finding 80% or more of the roots in the top 2 or 3 feet of the soil, with only a few deeper sinker roots. Because the London Plane can transport oxygen to the roots, roots can, and do, grow into much greater depths of the soil, where moisture can often be found, even in the middle of a parched summer when other trees are fading due to heat and lack of moisture in the upper soil layers. This ability to transport oxygen to roots also allows London Plane roots to grow in water, where other tree's roots die of suffocation. Apple Confidential - Do Not Distribute Date of Report: September 21, 2011 Page 6 l�atural Habita� Sycamores in general are trees of the flood plains, where their roots can penetrate the loose alluvial soils to great depth, and tap deep water resources, and grow to immense sizes. The largest Sycamore in the United States is growing in a canyon in the desert in New Mexico, with scrubland in the desert, descending into the canyon reveals lush green even as temperature approach 110. Rlar�t[ng Because our part of Cupertino is also an alluvial fan, this can be natural habitat for sycamores. We are planning to take advantage of our soils in establishing these London Plane trees. Planting ho{es will be dug until we have reached good quality native soil, and any compaction removed. This will establish good soil drainage. We will carefully refill the hole to avoid any tree settling. Encouraging Deep Raoting With good soil drainage established, we will water the trees deeply, to encourage roots downward as quickly as possible, to reach the lower soil depths where water can be found. We plan to give the trees plenty of water in the early establishment years, but with a focus on intervaf befinreen waterings to encourage this downward rooting. Once established in this way, the trees will be able to survive on their own in the event of irrigation restrictions and even prolonged drought. C�ft�var Qf Chaice 'Columbia' is a cultivar containing a great deal of the genetics of the Eurasian Sycamore native to the Mediterranean, matching our own climate. Interestingfy, 'Columbia' performs much better than native California sycamore in the Bay Area, and also better than two other cultivars which have been tried locally in recent decades, and are proving to be disease and structure disasters. The industry is rapidly shifting to only'Columbia'. �� Apple Confidential - Do Not Distribute Date of Report: September 21, 2011 Page 7 �r�e D�is��sE�[on Ta�fe The following table summarizes the disposition of every tree surveyed including physical measurements and observations. Trees have been tagged in the field with aluminum tags corresponding to the numbers referenced in the table and exhibit. Trunk diameters were measured at breast height (DBH) 54" above the adjacent ground, as required by the City of Cupertino. Tree height and spread was also estimated by visual observation.
