Below is a matrix style overview of protected-size trees (non-exempt species, 4-inches diameter at 4.5 feet above grade on site, and adjacent to the site). In the table, the CTA (Contract Town Arborist) has outlined expected impacts to each tree, along with suggestions for adjustments to the plan set (if applicable) that will optimize tree survival over the long term. The CTA calculated the appraised value of each tree, which can be used as a tool for determining the proper security bond amount to have the applicant post with the Town as a hedge against site plan-related tree damages (if applicable). Appraised values can also be used to determine damage fees if trees are determined during or after construction to have been damaged such that mitigation is required. Mitigation replacement rate and size is noted for each tree in the case that removal or damage to trees occurs.

Minimum 6 foot offset is suggested for smaller diameter trees to maintain soil moisture and preserve extended lateral woody roots. No applicant plan changes required. Use RPZ fencing as shown on CTA’s marked up tree map at 8 feet to 15 feet radius offset from trunk, in all directions. Use trunk buffer wraps for above ground protection of lower trunk. 3 X $250 = $750. 24” Box 1 Calculated per the newest edition (10th edition, 2nd Printing) of Guide for Plant Appraisal, 2019. The Trunk Formula Technique (TFT) was the specific technique noted in the Guide used to determine the dollar valuations noted in Table 1.0(a). Palm appraisals are performed differently, using a calculation of replacement cost, and then multiplying that cost by a condition rating factor and a functional limitations factor.

Current distance from driveway to trunk edge is shown on sheet C-1 at +/- 7 horizontal feet. However, in reality, it is simply a gravel filled driving area, which bleeds into the landscape surrounding tree #42 at just 2 to 4 feet north of the tree trunk edge (see digital images section of this report). No Moderate $7,200. 22 (Although for palms, this can be reduced down to roughly 5 to 10 feet offset radius). Suggest either (1) increase offset distance of the proposed driveway’s concrete banding to approximately 5 or 10 feet offset radius from trunk edge, or (2) build driveway with concrete banding at current proposed location 2 feet offset from trunk using a “zero cut” type build regime where the entire baserock base section is floated over grade, by using a TRIAXIAL GEOGRID OR BIAXIAL GEOGRID as an underlayment, pinned down over existing grade elevation soil, and compacting the class II baserock base material over the geogrid, which would raise the elevation of the roadway base and concrete banding to 12 inches above surrounding grade, which may still be ADA-compliant, if the edging can be tapered in some manner to avoid a trip hazard (by using a soil edging that tapers from 12 inches height above grade at the edge of the concrete banding, down to to zero inches at- grade some lateral distance out from the banding). Use trunk buffer wraps as shown on CTA’s tree map markup to protect trunk. Use chain link root protection zone (RPZ) fence perimeter at 0 to 15 feet radius offsets from trunk in a full perimeter as shown on CTA’s tree map markup, to protect the root zone from being compacted and rutted (damaged) during contractor ingress, egress, storage, staging, etc. on site. 3 X $250 = $750. 24” Box ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 5 of 37 Site Address: 14300 Lora Drive, Los Gatos, CA Version: 9/25/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved 1 Tree Tag Number / Overall Condition Rating/ Disposition 2 Impacts Expected if Site were Built as Currently Proposed on Applicant Sheet C-1 Version 8/17/2020 3 Large Protected Tree (LPT)?

No applicant plan changes required. Tree is located in close proximity to proposed new grassy swale grading and proposed new joint trench (JT) alignment. However, the negative effects from these actions in terms of actual, on the ground root loss to this tree are considered “negligible”, because of the special situation concerning this neighbor property owner (17525 Wedgewood Avenue): the entire property, for some unknown reason, was built up approximately 3 vertical feet in elevation, such that tree #46 effectively sits at 36 inches elevation above the soil surface elevation of 14300 Lora Drive. Given that a tree’s root system is typically about 4 to 5 feet depth below the trunk at the very most, and extends out from trunk laterally between zero and 2 feet depth, this means that the entire tree #46 lateral root mass is essentially contained in the fill soil “pad” floating 3 feet above surrounding pre-project grade, and would not be subject to any damages from any type of work occurring next door at 14300 Lora Drive. 3 X $250 = $750. 24” Box 2020-21 Town of Los Gatos In-lieu fee equivalent = $250 per each required 24” box mitigation tree planting not installed on the site.

The CTA assessed the entire set of plans, with the civil grading plan sheet C-1 dated 8/17/2020 used as the tree map markup embedded in this report. Tree data were collected and assembled by the CTA in section 11.0 of this report. Tree tags were affixed by the CTA to the mainstems of the on-site trees. The CTA’s tags are professional grade racetrack shaped aluminum tags numbering “41” through “46” (only affixed to the onsite trees #41, 42, but attached using nails to the wooden property line fence in front of the various off-site neighbor trees). The CTA’s recommendations in section 4.0 of this report are based on published information in various standard arboriculture texts, such as the series of Best Management Practices (BMP) companion publication (booklets) published by International Society of Arboriculture that are periodically updated over time. The series of BMP booklets accompany the ANSI-A300 USA standards for tree care used by U.S.-based tree care companies. Additional supporting information includes digital images archived by the CTA as section 10.0, a tree map markup JPEG embedded as section 12.0, and an appraisal data worksheet attached as section 13.0. The CTA utilized a forester’s D-tape to determine tree mainstem (trunk) diameters at 4.5 feet above grade. The D-tape is a circumferential tape that converts actual trunk circumference to an averaged diameter in inches and tenths of inches. Tree heights were determined using a digital Nikon Forestry Pro 550 hypsometer. Tree canopy spread diameters were estimated visually or paced off. The tree canopy driplines shown as black clouding on the tree map markup are approximate only. 3.0 Town of Los Gatos – What Trees are Protected? Per the most recent (2015) iteration of the Town of Los Gatos tree ordinance (Town Code Chapter 29 – Zoning Regulations, Article 1), the following regulations apply to all trees within the Town’s jurisdiction (wordage adjusted): 1. All trees with at least a single mainstem measuring four (4) inches diameter or greater at 4.5 feet above grade are considered “Protected Trees” when removal relates to any development review. 2. 12 inch diameter (18 inch multistem total) trees on developed residential property not currently subject to development review. 3. 8 inch diameter (8 inch multistem total) blue oak (Quercus douglasii), black oak (Quercus kellogii), California buckeye (Aesculus californica), and Pacific madrone (Arbutus menziesii) on developed residential lots not currently subject to development review. 4. 8 inch diameter (8 inch multistem total) trees on developed residential property not currently subject to development review, on lots in the designated Hillside Area per the official Town map.

All trees with a single mainstem or sum of multiple mainstems totaling 48 inches diameter or greater at 4.5 feet above grade are considered “Large Protected Trees” (LPT). 6. All oak species (Quercus spp.), California buckeye (Aesculus californica), and Pacific madrone (Arbutus menziesii) with one or more mainstems totaling 24 inches diameter or more at 4.5 feet above grade are considered “Large Protected Trees” (LPT). 7. Section 29.10.0965. Prohibitions: A permit is required to prune, trim, cut off, or perform any work, on a single occasion or cumulatively, over a three- year period, affecting 25% or more of any Protected Tree (including below ground root system). 8. Section 29.10.0965. Prohibitions: A permit is required to prune, trim, or cut any branch or root greater than four (4) inches in diameter of a Large Protected Tree. 9. Section 29.10.0965. Prohibitions: A permit is required to conduct severe pruning on any protected tree. Severe pruning is defined in section 29.10.0955 as “topping or removal of foliage or significant scaffold limbs or large diameter branches so as to cause permanent damage and/or disfigurement of a tree, and/or which does not meet specific pruning goals and objectives as set forth in the current version of the International Society of Arboriculture Best Management Practices-Tree Pruning and ANSI A300-Part 1 Tree, Shrub, and Other Woody Plant Management-Standard Practices, (Pruning).” 10.

Project Arborist (“PA”): Initial Signoff It is recommended that a third party ASCA registered consulting arborist or ISA Certified Arborist with good experience with tree protection during construction be retained by the applicant, to provide pre-project verification that tree protection and maintenance measures outlined in this section of the arborist report are adhered to. Periodic (e.g. monthly) inspections and summary reporting, if required as a project condition of approval, are suggested in order to verify contractor compliance with tree protection throughout the site plan project. This person will be referred to as the project arborist (“PA”). The PA should monitor soil moisture within the root protection zones of trees being retained, using a Lincoln soil moisture probe/meter or equivalent. If required, inspection reports shall be sent to Ms. Jocelyn Shoopman, Associate Planner (jshoopman@losgatosca.gov). Sample wordage for a condition of approval regarding monitoring of tree protection and tree condition: “The required protective fencing shall remain in place until final landscaping and inspection of the project. Project arborist approval must be obtained and documented in a monthly site activity report sent to the Town. A mandatory Monthly Tree Activity Report shall be sent at least once monthly to the Town planner associated with this project (jshoopman@losgatosca.gov) beginning with the initial tree protection verification approval letter”. 2. Project Team Pre-Project Adjustments, Clarifications, and Limits Suggested or Required: 2a. Tree Protection Fencing and Trunk Buffer Wraps: Fence off trees #41, #42, and #45 using chain link fencing per the distances indicated as red dashed lines shown to scale on the CTA’s tree map markup below in this arborist report. Install trunk buffer wraps around trees #41 and #42 per the specifications listed below in this recommendations section of the arborist report. 2b. Frond Tie-Up: Tie up the fronds of palm #42 as needed to achieve adequate airspace clearance during machinery ingress/egress, thereby avoiding damage to the canopy.

Geogrid for Driveway: Utilize a biaxial or triaxial geogrid of high enough load rating to provide robust underlayment properties for the area roughly zero to 20 horizontal feet from palm #42 (see CTA’s tree map markup in this report, showing a yellow highlighted area indicating the zone where geogrid use may be appropriate). Eliminate all proposed baserock base section excavation by raising elevation of the driveway, such that the geogrid is placed at existing grade (relative 0.0 feet), and the baserock base is built up above 0.0 relative grade. Build the concrete banding over grade, which will result in a total elevation change of somewhere between 6 inches and 12 inches above existing soil grade. Consult with geogrid manufacturer and/or supplier to determine how much reduction in baserock base section thickness can be achieved using the geogrid underlayment and still maintain spec load bearing properties for the driveway. If grade elevation rise creates a trip hazard that does not conform to ADA standards, then taper the concrete banding in the area of palm #42 using soil and/or other materials to “feather out” the grade as a long taper ending at zero inches. See sketch on this page for an example. The image at left shows how a geogrid is utilized to create a “zero cut” no-dig system that allows for 100% tree root preservation. Note that if the elevation rise of a “no dig” type driveway will be a problem that cannot be resolved through use of a tapered edging shown in the above sketch, then redesign the driveway to include a northward bend for the area adjacent to palm #42, such that the concrete banding remains at least 7 horizontal feet offset from the trunk edge of palm #42. Upper right: Although this is not technically a “no dig” system, the civil on this WLCA project was able to reduce the total cut to 4 inches on this project, and raising the edging to 4 inches above grade. The soil taper was backfilled from 4 inches above grade at the edging, to zero inches above grade near to the tree buttress root flares, as shown in the sketch, courtesy of Sandis Civil, Silicon Valley Office.

Trunk Buffer Wrap Type III Protection: Prior to demolition commencement, install trunk buffers around all trees being retained on-site (#41, #42). Wrap one (1) entire roll of orange plastic snow fencing around the trunk of each single on-site tree, between grade and 6 to 8 feet above grade to create a padding of at least 1 to 2 inches thickness around each tree trunk. Stand 2x4 wood boards upright, side by side, around the entire circumference of the orange plastic wraps. Affix using duct tape (do not use wires or ropes). See spec image at right showing the wooden boards correctly mounted against one entire roll of orange snow fencing, such that the wood does not actually touch the trunk at all. 4. (Required) Chain Link Fencing Type I and/or Type II Root Protection Zone (RPZ): Prior to demolition commencement, erect chain link fencing panels set on moveable concrete block footings (see sample image below right). Wire the fence panels to iron layout stakes pounded 24 inches into the ground at the ends of each fence panel to keep the fence route stabilized and in its correct position. Do not wire the fence panels to the trunks of the trees. These panels are available commonly for rent or purchase. Fence routes: Per the red dashed lines indicated on the CTA’s tree map markup, drawn to scale, below in this arborist report. This fencing must be erected prior to any heavy machinery traffic or construction material arrival on site. The protective fencing must not be temporarily moved during construction. No materials, tools, excavated soil, liquids, substances, etc. are to be placed or dumped, even temporarily, inside the root protection zone or “RPZ”. No storage, staging, work, or other activities will be allowed inside the RPZ except with PA monitoring.

New Plantings / Tree Installation Specs (if applicable): Ideally, two (2) high flow type adjustable bubblers each emitting 1/2 to 2 gallons per minute (2GPM), depending on percolation rate of planting pit, are set over the rootball of each single tree planting, and each tree is installed with two (2) or three (3) 2-inch diameter wooden planting stakes (not the shipping stake), with a set of figure-8 Cinch Ties ™ affixed per the standard spec image at right. Note how the tree stakes are cut to just above the elevation of the Cinch-Ties to avoid abrasion between the stakes and the limbs and trunk during wind movement. A watering berm consisting of site soil is formed around the edge of the rootball to force irrigation water to pool up directly over the rootball, as seen in the image below in this arborist report. Above Right: Spec planting at a site on which the CTA consults, June, 2020. Note that the shipping stake was removed from the mainstem, and a narrow diameter bamboo pole was tied to the mainstem using biodegradable masking tape. This is considered a Best Management Practice at this particular site, because the mainstem was leaning off-vertical. Do not allow the large diameter wooden shipping stake to remain tied to the mainstem, as this will cause permanent irreversible problems with tree stability over time. Below Right: Proper installation of a new 24” box size tree with two (2) high flow type ½ GPM to 2.0 GPM (gallon-per-minute) flood bubblers seen inside a steeply sloped watering berm built using site soil. The watering berm is built up directly over the rootball edge, which forces irrigation water directly downward into the rootball via gravity. Total volume of water flow typically needs to be at least +/-1 gallon per minute, in order to physically flood the watering berm and force water downward into the rootball via gravity flow. Next Page: Walter Levison and Dave Muffly Planting Spec Sheet, indicating correct irrigation and watering berm building procedures for first 4 years (sandy soils may require significantly greater irrigation volume than indicated).

Temporary Irrigation During Construction: It is suggested that the applicant’s project arborist monitor soil moisture using a soil moisture probe and/or a soil recovery device, to ensure that root zones are being kept irrigated to field capacity soil moisture per the following irrigation regime: a. Chinese pistache #41 at front yard: 50 to 100 gallons per week, applied 1x/week. b. Canary Island palm #42 at driveway: 50 to 100 gallons per week, applied 1x/week. c. Coast redwood #45 at left side of rear yard on neighbor’s property: 50 to 100 gallons per week, applied 1x/week. o Apply indicated water volume all on a single day during a single application, such as by garden hose running at high volume. o If runoff of water will be a problem, then build a 6 inch tall watering berm along the chain link fence perimeters to contain the irrigation water and force it downward via gravity. o Alternatively, a straw wattle can be pinned down over the ground using wooden dowels, as a quick watering berm that may be far more easily maintained than a soil watering berm that is subject to damage by construction personnel foot traffic, etc. See sample image below as an example of how this is done.

New property development. (a) A tree surve y shall be conducted prior to submittal of any developm ent application proposing the removal of or impact to one or more protected trees. The developm ent application shall include a Tree Survey Plan and Tree Preservation Report based on this surve y. The tree survey inventory numbers shall correspond to a num bered m etal tag placed on each tree on site during the tree survey. The tree surve y plan shall be prepared by a certified or consulting arborist, and shall include the following inform ation: (1) Location of all existing trees on the property as described in section 29.10.0995; (2) Identif y all trees that could potentially be affected by the project (directl y or indirectly- imm ediately or in long term), such as upslope grading or com paction outside of the dripline; (3) Notation of all trees classified as protected trees; (4) In addition, for trees four (4) inches in diam eter or larger, the plan shall specif y the precise location of the trunk and crown spread , and the species, size (diam eter, height, crown spread) and condition of the tree. (b) T he tree survey plan shall be reviewed b y the Town’s consulting arborist who shall, after m ak ing a field visit to the property, indicate in writing or as shown on approved plans, which trees are recommended for preservation (based on a retention rating of high/moderate/low) using, as a m inimum, the Standards of Review set forth in section 29.10.0990. This plan shall be m ade part of the staff report to the Town reviewing bod y upon its consideration of the application for new property developm ent; (c) W hen development im pacts are within the dripline of or will affect any protect ed tree, the applicant shall provide a tree preservation report prepared by a certified or consulting arborist. The report, based on the findings of the tree survey plan and other relevant inform ation, shall be used to determ ine the health and structure of existing trees, the effects of the proposed developm ent and vegetation rem oval upon the trees, recommendations for specific precautions necessary for their preservation during all phases of development (demolition, grading, during construction, landscapin g); and shall also indicate which trees are proposed for removal. The tree preservation report shall stipulate a required tree protection zone (TPZ) for trees to be retained, including street trees, protected trees and trees whose canopies are hanging over the project site from adjacent properties. The TPZ shall be fenced as specified in section 29.10.1005: (1) T he final approved tree preservation report shall be included in the building perm it set of developm ent plans and printed on a sheet titled: Tree Preservation Instructions (Sheet T -1). Sheet T-1 shall be referenced on all relevant sheets (civil, dem olition, utility, landscape, irrigation) where tree im pacts from im provem ents m ay be shown to occur; (2) T he T own reviewing bod y through its site and design plan review shall endeavor to protect all trees recomm ended for preservation b y the Town’s consulting arborist. The Town reviewing body m ay determ ine if any of the trees recommended for preservation should be removed, if based upon the evidence subm itted the reviewing body determ ines that due to special site grading or other unusual characteristics associated with the propert y, the preservation of the tree(s) would significantly preclude feasible developm ent of the property as described in section 29.10.0990; ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 17 of 37 Site Address: 14300 Lora Drive, Los Gatos, CA Version: 9/25/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved (3) Approval of final site or landscape plans by the appropriate Town reviewing body shall com ply with the following requirem ents and conditions of approval: a. T he applicant shall, within ninety (90) days of final approval or prior to issuance of a grading or building perm it, whichever occurs first, secure an appraisal of the condition and value of all trees included in the tree report affected by the developm ent that are required to rem ain within the development using the Tree Value Standard m ethodolog y as set forth in this Chapter. The appraisal of each tree shall recognize the location of the tree in the proposed development. T he appraisal shall be performed in accordance with the current edition of the Guide for Plant Appraisal published by the Council of Tree and Landscape Appraisers (CTLA) and the Species and Group Classification Guide published by the W estern Chapter of the International Societ y of Arboriculture. The appraisal shall be perform ed at the applicant's expense, and the appraisal shall be subject to the Director's approval. b. T he site or landscape plans shall indicate which trees are to be rem oved. However, the plans do not constitute approval to rem ove a tree until a separate permit is granted. The propert y owner or applicant shall obtain a protected tree rem oval perm it, as outlined in section 29.10.0980, for each tree to be removed to satisf y the purpose of this division. (d) Prior to acceptance of proposed developm ent or subdivision im provem ents, the developer shall subm it to the Director a final tree preservation report prepared by a certified or consulting arborist. T his report shall consider all trees that were to rem ain within the developm ent. The report shall note the trees' health in relation to the initially reported condition of the trees and shall note any changes in the trees' num bers or physical conditions. The applicant will then be responsible for the loss of any tree not previously approved for removal. For protected trees, which were rem oved, the developer shall pa y a penalty in the am ount of the appraised value of such tree in addition to replacem ent requirem ents contained in section 29.10.0985 of this Code. The applicant shall rem ain responsible for the health and survival of all trees within the development for a period of five (5) years following acceptance of the public im provem ents of the development or certificate of occupancy. (e) Prior to issuance of any dem olition, grading or building perm it, the applicant or contractor shall submit to the Building Department a written statem ent and photographs verif ying that the required tree protection fence is installed around street trees and protected trees in accordance with the tree preservation report. (f) If required by the Director and conditioned as part of a discretionary approval, a security guarantee shall be provided to the Town. Prior to the issuance of any perm it allowing construction to begin, the applicant shall post cash, bond or other security satisfactory to the Director, in the penal sum of five thousand dollars ($5,000.00) for each tree required to be preserved, or twenty-five thousand dollars ($25,000.00), whichever is less. The cash, bond or other security shall be retained for a period of one (1) year following acceptance of the public im provements for the developm ent and shall be forfeited in an am ount equal to five thousand dollars ($5,000.00) per tree as a civil penalt y in the event that a tree or trees required to be preserved are rem oved, destroyed or severely dam aged. (g) An applicant with a proposed developm ent which requires underground utilities shall avoid the installation of said utilities within the dripline of existing trees whenever possible. In the event that this is unavoidable, all trenching shall be done using directional boring, air-spade excavation or b y hand, tak ing extreme caution to avoid damage to the root structure. W ork within the dripline of existing trees shall be supervised at all times by a certified or consulting arborist. (h) It shall be a violation of this division f or any property owner or agent of the owner to fail to com ply with any developm ent approval condition concerning preservation, protection, and m aintenance of any protected tree.

Arborist Disclosure Statement: Arborists are tree specialists who use their education, knowledge, training, and experience to examine trees, recommend measures to enhance the beauty and health of trees, and attempt to reduce the risk of living near trees. Clients may choose to accept or disregard the recommendations of the arborist, or to seek additional advice. Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Tree are living organisms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborist cannot guarantee that a tree will be healthy or safe under all circumstances, or for a specified period of time. Likewise, remedial treatments, like any medicine, cannot be guaranteed. Treatment, pruning, and removal of trees may involve considerations beyond the scope of the arborist’s services such as property boundaries, property ownership, site lines, disputes between neighbors, and other issues. Arborists cannot take such considerations into account unless complete and accurate information is disclosed to the arborist. An arborist should then be expected to reasonably rely upon the completeness and accuracy of the information provided. Trees can be managed, but they cannot be controlled. To live near trees is to accept some degree of risk. The only way to eliminate all risk associated with trees is to eliminate the trees. 9.0 Certification I hereby certify that all the statements of fact in this report are true, complete, and correct to the best of my knowledge and belief, and are made in good faith.

Canopy extends into the airspace of the 14300 Lora Drive property, but will not conflict with any proposed site work because of its height above grade. Given that the 17525 Wedgewood property has been built entirely over a 3 foot height fill soil “pad”, the root system of this tree is assumed to be contained mainly within the fill soil pad volume, which means that proposed new work occurring at 14300 Lora Drive will be occurring below the elevation of the lateral root system of this palm, with zero negative impact on the root system of tree #46. n/a n/a ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 32 of 37 Site Address: 14300 Lora Drive, Los Gatos, CA Version: 9/25/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved Overall Tree Condition Ratings / Breakdown of Numeric Ranges (New, Per Guide for Plant Appraisal, 10th Edition): 00 - 05% = Dead 06 - 20% = Very Poor 21 – 40% = Poor 41 – 60% = Fair 61 – 80% = Good 81 – 100% = Exceptional ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 33 of 37 Site Address: 14300 Lora Drive, Los Gatos, CA Version: 9/25/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved Tree Conservation Suitability (TCS) Ratings 2 A tree’s suitability for conservation is determined based on its health, structure, age, species and disturbance tolerances, proximity to proposed cutting and filling, proximity to proposed construction or demolition, and potential longevity, using a scale of good, fair, or poor (Fite, K, and Smiley, E. T., 2016). The following list defines the rating scale. Note that if the applicant’s proposed site work can be offset to relatively far linear offset distances from a tree’s trunk edge, a tree’s Tree Conservation Suitability (TCS) rating may be elevated by one rating tier, given that there would be a corresponding reduction in expected future root zone impacts. Thus, specific adjustments to the applicant’s proposed plans (as itemized by the CTA in Summary Table 1.0(a) above in this report) could boost the TCS ratings from “Poor” to ‘Moderate’ or ‘Good’. TPS Ratings Range of values Good 80-100 Trees with good health, good structural stability and good expected longevity after construction. Moderate 60-79 Trees with fair health and/or structural defects that may be mitigated through treatment. These trees require more intense management and monitoring, before, during, and after construction, and may have shorter life expectancy after development. Poor <59 Trees are expected to decline during or after construction regardless of management. The species or individual may possess characteristics that are incompatible or undesirable in landscape settings or unsuited for the intended use of the site. TCS Ratings Worksheet Factors (Total Possible: 100 Points) Health (1-15) Root Cut/Fill Distance from Trunk (1-15) Structure Defects (1-15) Construction Tolerance of the tree species (1-15) Age relative to typical species lifespan (1-10) Location of construction activity (1-10) Soil quality/characteristics (1-10) Species desirability (1-10) 2 Derived from Fite and Smiley, 2016.

Alternative material: chain link fence panels set over concrete block-type footings, with the fence panels wired to steel pins pounded 24 inches into the ground at both ends of each panel. RB: Root buffer consisting of wood chip mulch lain over existing soil as a 12 inch thick layer, overlain with 1 inch or greater plywood strapped together with metal plates. This root buffer or soil buffer should be placed over the entire width of the construction corridor between tree trunks and construction. RP: Root pruning. Prune woody roots measuring greater than or equal to 1 inch diameter by carefully back -digging into the soil around each root using small hand tools until an area is reached where the root is undamaged. Cleanly cut through the root at right angle to the root growth direction, using professional grade pruning equipment and/or a Sawzall with wood pruning blade. Backfill around the cut root immediately (same day), and thoroughly irrigate the area to saturate the uppermost 24 inches of the soil profile. BDRP: Back-dig root pruning: Hand-dig around the broken root, digging horizontally into the open soil root zone until a clean, unbroken, unshattered section of the root is visible. Proceed as per ‘root pruning’. RCX: Root crown excavation. Retain an experienced ISA-Certified arborist to perform careful hand-digging using small trowels or other dull digging tools to uncover currently-buried buttress root flares. Digging shall occur between trunk edge and at least two (2) feet horizontal from trunk edge. The final soil elevation will be at a level such that the tree’s buttress roots visibly flare out from the vertical trunk. TB: Trunk buffer consists of 20-40 wraps of orange plastic snow fencing to create a 2 inch thick buffer over the lowest 8 feet of tree trunk (usually takes at least an entire roll of orange fencing per each tree). Lay 2X4 wood boards vertically, side by side, around the entire circumference of the trunk. Secure buffer using duct tape (not wires). F: Fertilization with slow-release Greenbelt 22-14-14 tree formula, as a soil injection application using a fertilizer injection gun. This brand and formulation is commonly used by reputable tree care companies in the Bay Area. Apply at label rate and injection hole spacing. M: 4-inch thick layer of chipper truck type natural wood chips (example source: Lyngso Garden Supply, self pick-up). Do not use bark chips or shredded redwood bark. W: Irrigate using various methods to be determined through discussion with General Contractor. Irrigation frequency and durat ion to be determined through discussion and/or per directions in this report. Native oak species typically require 1x/month irrigation, while other tree species tend to prefer 2x/month or 4x/month moderate to heavy irrigation during construction. P: Pruning per specifications noted elsewhere. All pruning must be performed only under direct site supervision of an ISA Certified Arborist, or performed directly by an ISA Certified Arborist, and shall conform to all current ANSI A300 standards. MON: A Project Arborist must be present to monitor specific work as noted for each tree.

The CTA added the following items to this sheet for reference purposes: a. Tree tag numbers are noted in black numeric oversized type. Important Note: The numbers on the CTA’s map refer to new racetrack shaped professional grade aluminum tags affixed to the trees or on the fencing in front of each tree, by the CTA. They are affixed to the mainstem of each tree at between 4 and 6 feet above grade. b. Tree plot dots are in some cases added as new, or blackened, for clarity. Most of the CTA’s survey trees were not plotted by the applicant’s civil surveyor. c. Canopy driplines of most of the trees were drawn out by the CTA to approximate scale, using black clouding. d. Red dashing indicates suggested chain link root protection zone (RPZ) fencing routes, drawn to approximate true scale to indicate optimal placement in terms of root protection and preservation for trees #41, 42, and #45. e. Yellow highlight along the south boundary of the map (bottom edge of map markup) indicates the applicant’s proposed joint trench (JT) and grassy swale grading location. f. Yellow highlighting along the driveway indicates the location suggested by the CTA for use of biaxial geogrid or triaxial geogrid as an underlayment that would be pinned down directly over the existing soil at grade, over which the class II baserock base section would be tamped down. This would raise the elevation of the driveway significantly. This is an item for further discussion, since use of robust versions of biaxial or triaxial geogrid can allow for reduction of baserock base section thickness by as much as 50%. The goal here is to avoid all excavation cuts below grade elevation, such that the root system of tree #42 can be retained as-is without damages from the applicant’s current proposed plan to excavate 12 inches below grade for baserock base installation and concrete banding installation. g. Blue highlight indicates areas where 1x/week heavy irrigation would be helpful in increasing tree growth (vigor) by boosting soil moisture in the root zone to field capacity.

The dollar values of each survey tree derived from these calculations are useful in helping determine the monetary fines for construction team violations of the Town of Los Gatos tree ordinance, and for other Town Staff purposes. For instance, if a tree is found by an ISA Certified Arborist (e.g. the Project Arborist, or the Contract Town Arborist) to be “50% damaged” in terms of below and/or above-ground losses to structure and/or health (vigor), the fine assessed on the construction team might be calculated as 50% of the tree’s appraised dollar value.

MULTI STEM TREES: For trees with multiple mainstems, the total of all mainstem cross sectional areas was used as the "trunk area" calculation. For trees with mainstems larger than 30 inches diameter each, an "adjusted trunk area" or "ATA" value is used, from a table of values in the older 9th edition of the Guide for Plant Appraisal.The ATA value is smaller than the actual trunk diameter, and brings the tree's appraised dollar value down to a more "reasonable" level. 3. NEIGHBOR TREES: For neighbor-owned trees that were not accessible by the CTA, the trunk diameter was estimated from a distance to the best of the CTA's ability. 4. CONDITION RATINGS / APPRAISAL TABLE VS. DATA TABLE: Because of the new appraisal methods outlined in the 2019 edition of the Guide for Plant Appraisal, 10th edition 2nd printing, the condition ratings calculated in the "Overall Condition Rating / Weighted Method" column, and the data noted in the health and structure columns of this spreadsheet (with calculations embedded), may in some cases be slightly different from data in the CTA's arborist report tree data table. The CTA attempted to keep overall condition rating values as consistent as possible between the two data tables (i.e. the appraisal data table and the tree data table in the arborist report).
