Below is a matrix style overview of protected-size trees (non-exempt species, 4-inches diameter at 4.5 feet above grade). 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. Note: Only trees within relatively close proximity of proposed work are included in this tree study (e.g. tree trunks located between approximately zero and 30 linear feet of current proposed new grading, utility trenching, excavation, haul routes, landscaping, etc. as shown on proposed plans, and trees with canopy driplines that encroach onto the subject property.

Existing deep excavation is 16 feet offset from trunk. Existing putting green has damaged the root system of this tree most likely, and the tree has been limbed up (pruned) to remove all lower elevation limbs. The tree may not actually be worth retaining, given its current impacted state. Sheet C2.1 shows new retaining wall at 8 feet from trunk edge, which would be a severe violation of the Critical Root Zone. Suggest consider removing this tree, unless retaining wall can be pushed significantly farther offset distance from trunk (although the tree is not actually worth the cost of major redesign). Sheet C3.1 shows new storm drainage systems (daigramatic representation) with excavation at 4 or 5 feet offset from trunk.

The existing concrete patio is assumed to have a deep baserock base foundation that likely required excavation and recompaction during installation, resulting in severe root loss to the tree. It is not clear as to how tree #925 has survived through severe root loss on four sides of the root zone, at distances all less than the Critical Root Zone structural stability minimum offsets. Proposed new work will encroach to distances approximately at (or farther than) existing 100 year old residence foundation footing conditions. Given that this tree is already in “poor” overall condition per the CTA’s tree data table, it may prematurely die within 10 to 15 years, regardless of proposed new construction buildout. 6 X $250 = $1,500. 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 13 of 51 Site Address: 62 Ellenwood Avenue, Los Gatos, CA Version: 6/3/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved Line Number Tree Tag Number / Common Name Expected Tree Disposition Critical Root Zone (CRZ) Radius Suggested for Optimal Structural Stability Large Protected Tree (LPT)?

Neighbor-owned tree (not surveyed by project team) appears to be located near to where the proposed wooden steps will encroach in closest proximity to the north property line fence. Proposed wooden steps will be approximately 5 to 6 feet offset from the trunk edge of this tree. The impacts of the steps in terms of root loss to redwood #950 will depend on whether the stairs are simply supported by standard 4X4 wooden posts in dug pier holes in the ground, or whether the stair system will involve more substantial engineered landings and foundation footings in addition to small-diameter piers/posts. Note that significant damage to this tree’s root system is not an option, given that the tree is relatively very valuable, and owned by the neighbor to the north. Applicant shall verify proposed wood step footing types and layout.

However, the construction-related impacts to oaks being retained on site are quite severe, if the project were to be built as currently proposed per the applicant’s plan set. See summary table 1.0(a) items in bold black above in this report for the CTA’s suggested changes to the proposed plans to optimize tree survival. 2.0 Assignment & Background Walter Levison, Contract Town Arborist (CTA) was directed to tag and assess all Protected-Size (4-inch diameter and greater) trees in relatively close proximity to the proposed site plan project area, including off-site trees on neighboring properties which were expected to be negatively impacted by the applicant’s planned work. The CTA assessed the entire set of plans dated 4/23/20 (by Arcanum Architecture, BKF Civil, and Studio Green). Tree data were collected and assembled by the CTA in section 11.0 of this report. 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 and included in section 10.0, and a tree map markup attached as section 12.0. 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. The tree trunk plot dot locations shown on the CTA’s tree map markup for trees #950 and #951 on neighboring properties are considered rough approximate only, as they were not plotted by the applicant’s project team.

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 Mr. Sean Mullin, Associate Planner (smullin@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 (smullin@losgatosca.gov) beginning with the initial tree protection verification approval letter”. 1. (Continued) PROJECT ARBORIST “PA” / SPECIAL SITE MONITORING: The PA shall work with the project team to directly monitor a portion of the following items such as, but not limited to the following: 1a. Installation of a layer of biaxial or triaxial geogrid over the soil grade surface as an underlayment for the baserock base section of the proposed new driveway, dog run, and various walkways near trees #901, 902, 905, 906, 907, 908. ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 18 of 51 Site Address: 62 Ellenwood Avenue, Los Gatos, CA Version: 6/3/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved The PA shall verify that proposed new driveway and walkway and dog run work “edging” involves setting materials down to existing soil surface grade elevation only, and does not involve any edging prep excavation below existing grade elevations for installation of any edging or restraints. Right: Image showing TriAx installation at a CTA project in Menlo Park, 2020. Baserock is placed directly over the plastic geogrid shown in the image. 2. Project Team Pre-Project Adjustments, Clarifications, and Limits Suggested or Required: 2a. DRIVEWAYS / WALKWAYS / DOG RUN: Tensar TriAx triaxial geogrid model TX5, TX160, or TX7 (or equivalent) shall be laid over existing soil grade to avoid any excavation or grading for driveway sections, walkway sections, and dog run, within 20 feet of trees #901, 902, 905, 906, 907, and #908. These work items shall be constructed as “no dig, over grade” systems completely over existing soil grade, with no subbase prep or subbase recompaction. 2b. PATIO & LANDINGS / NORTH SIDE OF SITE: It is suggested that the applicant push proposed patio work and landings to at least 15 or 20 feet offset from the trunk edge of tree #910, to avoid severe root damage and/or root loss related to baserock base section excavation and other prep work associated with these items. 2c. SPA & WIDE WALKWAY & NARROW WALKWAY: It is suggested that the applicant push the proposed spa, wide walkways, and narrow walkways to at least 12 feet offset from the trunk of tree #909 to avoid severe root loss/damage. 2d. STORM DRAIN (SD) PIPES AND BOXES: The applicant shall push proposed storm drain pipe trenches and related facilities to at least 10 feet from trunk edge of tree #908, and 12 feet from trunk edges of trees #909, 915 and #916. 2e. POSSIBLE ADDITIONAL TREE REMOVAL: Applicant shall consider removal of protected size tree #921, due to the apparent unmitigable conflicts between proposed site work within the tree’s Critical Root Zone (structural root plate preservation minimum offset distance), and the existing condition rating of the tree (58%). The mitigation fee for removal would be $1,000, but this fee would be waived, given that the applicant’s proposed number of new tree plantings on site would far exceed this value. 2f. OAK #924: REMOVAL AND MITIGATION: The fee for mitigation of removal of tree #924 per applicant’s plan is $1,500. However, this fee will be waived, given that the value of proposed new trees to be installed on site far exceeds the canopy replacement fee for removal of this tree. ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 19 of 51 Site Address: 62 Ellenwood Avenue, Los Gatos, CA Version: 6/3/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved 2g. LANDSCAPE PLAN / SHEETS L3.1 & L3.2: The tree installations proposed per applicant sheet L3.1 will cause severe root loss/damage to trees #901 and #902. The proposed tree installations along the southwest side of the site will cause severe root loss/damage to all trees being retained along the southwest side of the site. There is no way to mitigate the root loss/damage to existing trees being protected in place (PIP) from planting pit digging that will occur, if the landscape plan is built out as currently proposed. This is a subject for further discussion between Town Staff and the applicant’s team. 2h. LANDSCAPE IRRIGATION PIPE TRENCHING: Proposed irrigation pipe trenching is typically the single most damaging item of an entire submittal set of plans, because the trench alignments are often placed parallel to the property boundaries, in very close proximity to valuable mature oaks and other high value trees. The applicant’s plan set does not include an irrigation plan sheet. Therefore, impacts from this trenching were not quantified at the time of writing. However, given the large number of trees and shrubs proposed to be installed along the property boundaries in direct conflict with large, mature high-value trees being retained both on and off site, the CTA expects extremely severe root loss to occur around most or all trees being retained at and adjacent to this site, as a result of irrigation pipe trenching, if pipes were to be installed in-line with the current proposed tree and shrub installation locations shown on sheet L3.1 and 3.2. Although it may be possible to run flexible over-grade irrigation tubing to the trees to reduce trenching impacts to existing mature trees being retained and protected on site, the root loss/damage caused by new tree planting pit installation per landscape plan sheets L3.1 and L3.2 may be nearly as severe as the pipe trenching impacts. This is a subject for further discussion between Town Staff and the applicant’s project team, given that the CTA has not reviewed any proposed irrigation plan sheets as of the date of writing. 2i. ELIMINATE PROPOSED RESTROOM FACILITY / GOLFING AREA WORK / STORM DRAIN: The CTA suggests that the proposed outdoor restroom facility, storm drain pipe and associated items, and golf putting area renovation, all be eliminated within 20 feet of the trunk edge of tree #923, to avoid causing severe root loss/damage to this tree, and allow for erection of TPZ fencing at 15 feet to 17 feet offset from the trunk edge. If any of these three (3) proposed applicant items shown on the proposed plan set were to be built as currently shown, then the damage to the root system of tree #923 would be severe, possibly causing premature tree death and/or destabilization of the root plate. 2j. WOODEN STAIR PIER FOOTINGS: The CTA suggests that all foundation work to support the proposed wooden stairs and associated landings running from the swimming pool down through the solar array be supported using only individual small-diameter piers set in individual small diameter post holes, dug at greater than or equal to 8 feet on-center spacing between posts, for areas within 25 feet of neighbor-owned redwood #950 (the project engineer will have to review and sign off on this general specification). 2k. NEIGHBOR OAK #951: Applicant’s project team shall survey-plot the accurate location of neighbor oak #951. It is suggested that the applicant’s team push all proposed stormwater detention system-related items to an offset of at least 10 feet from the southwest property line, to avoid causing severe root loss to the oak #951 lateral root system, which extends far into the 62 Ellenwood lot.

Pruning & Tree Maintenance: 3a. ISA Certified Arborist: Retain the services of an ISA Certified Arborist to perform or directly oversee site pruning work on trees requiring airspace clearance pruning or other tree maintenance. All pruning work on trees at this project will need to be performed directly by an ISA Certified Arborist, or under full-time on-site direct supervision of an ISA Certified Arborist. All pruning shall conform to the most current iteration (2017) of ANSI-A300 tree, shrub, and other woody plant maintenance / pruning and the Best Management Practices companion pamphlet to the ANSI-A300 pruning standards, published by International Society of Arboriculture. 3b. Perform endweight reduction pruning to shorten over-extended lateral limb systems (of certain trees to be determined) by removing the outermost end portions per ANSI A300 standards. 4. New Irrigation Piping and Landscape Plantings: 4a. Review: Provide an irrigation plan sheet to Town Staff for review. Per item #2h above in this recommendations section, all new irrigation hard PVC pipe trenching shall be offset at least 15 feet from the trunk edge of any tree being retained both on and off site. \ For areas within 15 feet of a tree being retained, use only over-grade “trenchless” systems such as flexible ½” diameter tubing that is UV-resistant and rated for installations on-grade, in order to avoid trenching which would otherwise destroy root systems of trees being retained. If possible, eliminate all new proposed plantings within 15 feet of an existing large mature tree to be retained (e.g. trees #901, 902). 5. (Optional) Trunk Buffer Wrap Type III Protection: Prior to demolition commencement, install trunk buffers around all trees being retained on-site: Wrap one (1) entire roll of orange plastic snow fencing around the trunk of each single 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 above 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.

(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. Alternative Fencing / Tube Posts and Rolled Chain Link: Using a professional grade post bounder, pound 7-foot long 2-inch diameter iron tube posts 24-inches into the ground, at 6 to 10-foot spacing maximum on-center, and hang steel chain link fencing material minimum 5-feet height on the tube posts. These materials are available for purchase at many retail and wholesale construction supply houses such as Home Depot, Lowe’s, Grainger’s, White Cap, Harbor Freight, etc. Pre-construction fence routes for trees being retained within 30 feet of new work: See the CTA’s red dashed lines indicating chain link fence routing, on the attached tree map markup. 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. 7. Signage: The RPZ fencing shall have one sign affixed with UV-stabilized zip ties to the chain link at eye level for every 15 linear feet of fencing, minimum 8”X11” size each, plastic laminated or printed with waterproof ink on waterproof paper, with wordage that includes the Town Code section that refers to tree fence protection requirements (wordage can be adjusted): ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 22 of 51 Site Address: 62 Ellenwood Avenue, Los Gatos, CA Version: 6/3/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved TREE PROTECTION ZONE FENCE ZONA DE PROTECCION PARA ARBOLES -NO ENTRE SIN PERMISO- -LLAME EL ARBOLISTA- REMOVAL OF THIS FENCE IS SUBJECT TO PENALTY ACCORDING TO LOS GATOS TOWN CODE 29.10.1025 PROJECT ARBORIST: TELEFONO CELL: EMAIL: Note: Walter Levison, Contract Town Arborist is an independent consultant working for Town of Los Gatos Planning Division Staff, and is not the “PROJECT ARBORIST”.

Water Spray: Spray off foliage of all trees within 20 feet of construction activity using a very high power garden hose or a pressure washer system set on low pressure to wash both the upper and lower surfaces of foliage. This helps keep the gas portals (stomata) unclogged for better gas exchange which is crucial for normal tree function. Spray should be applied approximately once-monthly, or when ambient airborne dust concentration is unusually high. 9. Tree Removal Permitting / Removal of Protected-Size Trees / Mitigation: It is suggested that the Town permit the removal of oak #921, with mitigation, if work is to occur within the tree’s Critical Root Zone of 20.5 feet radius offset from trunk edge, as is currently proposed. This is a subject for further discussion between Staff and the applicant’s team. Oak #924 will be removed per plan. Given the extensive nature of the applicant’s proposed landscape plan, there are no fees required for canopy replacement. Note, however, per the CTA’s items #2g and #2h above in this Recommendations section, proposed landscape tree planting pit locations shown on the applicant’s landscape plan sheet, and irrigation pipe trenching plans (not yet submitted by applicant) will have a severe negative effect on trees being retained. This is a subject for further discussion between Town Staff and the applicant’s team. New Plantings / Tree Installation Specs 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) wooden planting stakes (not the shipping stake), with a set of figure-8 Cinch Ties ™ affixed per the standard spec image below 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 outside edge of the rootball to force irrigation water to pool up directly over the rootball, as seen in the image at right and on the following page.

Temporary Irrigation During Construction (If Any): Volume per week: TBD. Application locations: TBD. Application methods: TBD. See image at right showing a 100-foot long soaker hose setup with wood chip mulch around a large coast redwood specimen being retained during construction on a Walter Levison project. Palo Alto, California. Other over-grade temporary irrigation techniques can be used, including a tow- behind water tank/spray apparatus, water truck, garden hose, high flow type bubblers, etc. 5.0 Tree Protection and Maintenance Directions per Town Code The following is excerpted directly from the 2015 iteration of the Town of Los Gatos tree ordinance sections which provide specific tree protection directions and limitations on root pruning and above-ground pruning: Sec. 29.10.1000. New property development. (a) A tree survey shall be conducted prior to subm ittal of any development application proposing the removal of or im pact to one or m ore protected trees. The developm ent application shall include a Tree Survey Plan and Tree Preservation Report based on this survey. The tree surve y inventory num bers shall correspond to a num bered metal tag placed on each tree on site during the tree survey. The tree survey 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; ASCA Registered Consulting Arborist #401 / ISA Tree Risk Assessment Qualified / ISA Certified Arborist #WE-3172A Cell: (415) 203-0990 / Email: walterslevisonjr@yahoo.com 25 of 51 Site Address: 62 Ellenwood Avenue, Los Gatos, CA Version: 6/3/2020 Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture  Walter Levison 2020 All Rights Reserved (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; (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.

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.

In this case, the tree m ay be replaced with a com bination of both the Tree Canopy Replacem ent Standard and in-lieu paym ent in an amount set forth by Town Council resolution paid to the Town Tree Replacement Fund. 3Single Family Residential Replacement Option is available for developed single fam ily residential lots under 10,000 square feet that are not subject to the Town’s Hillside Development Standards and Guidelines. All 15-gallon trees must be planted on-site. An y in-lieu fees for single fam ily residential shall be based on 24” box tree rates as adopted by Town Council. 4Replacem ent Trees shall be approved b y the Town Arborist and shall be of a species suited to the available planting location, proximity to structures, overhead clearances, soil type, com patibilit y with surrounding canopy and other relevant factors. Replacem ent with native species shall be strongly encouraged. Replacem ent requirements in the Hillsides shall comply with the Hillside Developm ent Standards and Guidelines Appendix A and Section 29.10.0987 Special Provisions--Hillsides. Sec. 29.10.0987. Special Provisions—Hillsides The Town of Los Gatos recognizes its hillsides as an im portant natural resource and sensitive habitat which is also a key com ponent of the Town’s identity, character and charm . In order to m aintain and encourage restoration of the hillside environm ent to its natural state, the Town has established the following special provisions for tree rem oval and replacem ent in the hillsides: (1) All protected trees located 30 or m ore feet from the prim ary residence that are rem oved shall be replaced with native trees listed in Appendix A Recommended Native Trees for Hillside Ar eas of the Town of Los Gatos Hillside Development Standards and Guidelines (HDS&G). (2) All protected trees located within 30 feet of the primary residence that are removed shall be replaced as follows: (a) If the removed tree is a native tree listed in Appendix A of the HDS&G, it shall only be replaced with a native tree listed in Appendix A of the HDS&G. (b) If the removed tree is not listed in Appendix A, i t m ay be replaced with a tree listed in Appendix A, or replaced with another species of tree as approved b y the Director. (c) Replacem ent trees listed in Appendix A m ay be planted anywhere on the property. (d) Replacem ent trees not listed in Appendix A m ay only be planted within 30 feet of the primary residence. (3) Replacement requirements shall com ply with the requirem ents in Table 3-1 Tree Canopy Replacement Standard of this Code. (4) Property owners should be encouraged to retain dead or declining trees where they do not pose a safety or fire hazard, in order to foster wildlife habitat and the natural renewal of the hillside environment.

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.

Canopy has been liontailed to remove inner and lower live wood and foliage: a practice that does not conform to the ANSI A300 (U.S.) pruning standards. Multiple cables are visible in tree. Open decay cavities are visible throughout the canopy, resulting from decay initiated at old pruning cut wounds. Therefore, it is going to be very difficult to manage this tree for long term safety. Critical Root Zone (CRZ) is roughly 18 feet offset radius. TPZ fencing should be erected at least 15 to 17 feet offset from the trunk edge of tree: the approx. Critical Root Zone offset radius from trunk edge. CTA suggests eliminating proposed renovation plans for the existing golfing area. Eliminate proposed outdoor restroom facility. Eliminate proposed storm drain (SD) pipe trench at west side of property. Elimination of all three (3) of the above items should allow for protection of the CRZ.

T., 2016). The following list defines the rating scale. Note that if proposed site work can be offset to farther linear distances from a tree’s trunk edge, a tree’s TCS rating may be elevated by one rating tier, given that there would be a corresponding reduction in expected future root zone impacts. 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.

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 duration 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 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. 13.0 Attached: Tree Location & Protection Fence Map Mark-up by the CTA The CTA marked up the applicant’s sheet L0.0 dated 4/23/2020 which is an amalgamated proposed site plan/landscape plan sheet. This markup is attached to the end of this report as a PDF markup using Adobe Pro, and the markups by the CTA may not be visible unless the viewer opens the document using Adobe Pro or Adobe CS. The CTA added the following items to this sheet for reference purposes: a. Tree tag numbers are noted in black numeric oversized type. b. Tree plot dots are in some cases blackened for clarity. The locations of neighbor trees #950 and #951 were rough-plotted by the CTA, as they were not surveyed by the applicant’s survey team. c. Canopy driplines for the two neighbor trees were drawn out by the CTA to approximate scale, using black clouding. d. Red dashed lines indicate chain link fencing tree root protection zones or root protection zones (TPZ or RPZ). However, as noted by the CTA on the tree map markup, the current available locations for TPZ fencing are not adequate to allow for root preservation or protection, given the current proposed extent of site work indicated on the applicant’s set of plans dated 4/23/2020. Most of the “Critical Root Zone” minimum required construction offset distances for protection of trees’ structural root plates will be violated, if the proposed plans are built out as currently proposed by the applicant.

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).
