Babby, Registered Consulting Arborist® August 3 , 2018 1.0 INTRODUCTION Swenson is planning to redevelop 400 and 420 Blossom Hill Road, Los Gatos, a site bordered by multi-family housing to the north, Blossom Hill Road to the south, Highway 17 to the west, and S.J.W.W. to the east. The project consists of demolishing two existing buildings, and constructing an assisted living facility named The Oaks at Los Gatos ( and will hold the address 400 Blossom Hill Road). As part of the planning submittal, Swenson has retained me to prepare this Arborist Report, and specific tasks assigned to execute are as follows (for conforming with Sections 29.10.1000 and 29.10.1005 of the Town Code): • Visit the site, performed on 5/19/17, 5/30/17, 3/7 /18 and 4/27 /18, to identify "protected trees"1 located either within, immediately adjacent to, or overhanging areas where development activities are planned (to include trees both on and offsite). • Determine each tree's trunk diameter at 54 inches above natural grade (rounded to the nearest inch). Trees with more than one diameter listed are formed by multiple trunks. • Estimate each tree's average canopy spread (rounded to nearest fifth). • Ascertain each tree's health and structural integrity, and assign an overall condition rating ( e.g. good, fair, poor or dead). • Designate each tree's suitability for preservation (e.g. high, moderate or low). • Assign numbers to the trees, which are shown on the site map in Exhibit B; the map is a copy of the Existing Conditions and Demolition Plan (Sheet Cl), prepared by Civil Engineering Associates and dated 4/24/18. • Identify which are defined by Town Code as a "large protected tree. "2 • Utilize photographs presented in my prior 5/1/18 report; see Exhibit C (photos represent existing conditions, and were obtained in either 2011, 201 7 or 2018). • Appraise the monetary values of protected trees planned for retention. • Review the entire 3/14/18 plan set submittal to ascertain potential impacts. • Provide project specific protection measures to help mitigate or avoid impacts to retained trees. • Prepare a written report that presents the aforementioned information, and submit via email as a PDF document. 1 Section 29.10.0960 of the Town Code defines a protected tree as having a 24" diameter trunk at 54" above natural grade. Exempt from this provision are fruit-or nut-bearing trees with trunk diameters <18", as well as select tree types listed within Section 29.10.0970(2) and having trunk diameters <24" (pursuant to Section 29.10 .0970 of the Code). 2 Section 29.10.0955 of the Town Code defines a large protected tree as any Quercus sp ., Aesculus californica or Arbutus menziesii with a diameter 224", or any other non-exempt species with a diameter of 248" (measured 54" above natural grade).

Babby, Registered Consulting Arborisf August 3, 2018 2.0 TREE COUNT AND COMPOSITION One-hundred thirty-nine (139) trees of ten various species were inventoried for this report. They are sequentially numbered as 1-33, 35-43, 45, 46, 49, 51, 53-70, 72-75 and 77-147,3 and the table below identifies their names, assigned numbers, counts and percentages. %OF NAME TREE NUMBER(S) COUNT TOTAL Blue elderberry 65,107,108,123,127, 130-132 8 6% California buckeye 100, 106, 109-122, 124-126, 128, 21 15% 133 8-12, 16-20, 22, 28, 29, 36, 38-40, Coast live oak 46, 51, 53-57, 61-64, 66, 67, 69, 72-67 48% 75, 77, 79, 83-85, 87-90, 92-99, 101- 105,129,134, 137-141, 143-145 Coast redwood 1-7, 13-15, 142, 146, 147 13 9% Eastern redbud 80-82 3 2% Holly oak 86,91 2 1% Incense cedar 41 1 1% Myoporum 49 1 1% Pacific willow 21, 23-27, 30-33, 35, 37, 45, 135, 15 11% 136 Valley oak 42,43,58-60, 68, 70, 78 8 6% Total 139 100% 3 The break in sequential numbering is due to a select number of dead/decayed trees having been removed since 2011; they include #34, 44, 47, 48, 50 , 52, 71 and 76. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 2 of 18 David L. Babby, Registered Consulting Arborisf August 3, 2018 Specific information regarding each tree is presented within the inventory table in Exhibit A. The trees' locations and assigned numbers are identified within the site map in Exhibit B, and photographs are presented in Exhibit C. As illustrated in the previous table, the site is populated predominantly by native oaks ( coast live and valley), followed by California buckeyes and Pacific willows. Thirty (30) trees are located on neighboring properties, and were inventoried for this report due to overhanging the site or being in direct proximity of anticipated offsite improvements; they include #1, 41-43, 49, 54-59, 94-101 and 137-147. As previously mentioned, all 139 inventoried trees are defined as protected trees per Town Code. Of these, the following 39 are defined as large protected trees : #12, 16-18, 21, 28, 29, 36, 38-40, 45, 51, 53-60, 64, 66, 68, 69, 72, 78, 79, 83, 84, 90, 93-95, 97, 99-101, 142 and 143. For identification purposes, round-metal tags with corresponding engraved numbers can be found affixed to the trunks or major limbs of trees. The exception to this includes the following: offsite trees #41, 42, 43, 49, 138 and 139, which are setback from the shared northern wall, and offsite trees #140 thru 147, which originate a notable distance inside the Caltrans Highway 17 easement. For #140 thru 147, tags were tied to a cable along the top of chain link fencing bordering the Cal trans property. The Oaks at Los Gatos, 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 3 of 18 David L. Babby, Registered Consulting Arborist® August 3, 2018 3.0 SUITABILITY FOR TREE PRESERVATION Each tree has been assigned either a "high," "moderate" or "low" suitability for preservation rating as a means to cumulatively measure its existing health; structural integrity; anticipated life span; remaining life expectancy; prognosis; location; size; particular species; tolerance to construction impacts; growing space; frequency of care needed; and safety to property and persons within striking distance. Descriptions these ratings are presented below; the high category is comprised of 12 trees (or 9%), the moderate category 69 (or 49%), and the low category 58 (or 42%). High: Applies to #12, 16, 17, 38, 40, 60, 83, 85, 94, 96, 97 and 104. These trees appear relatively healthy and structurally stable; have no apparent, significant health issues or structural defects; present a good potential for contributing long-term to the site; and seemingly require only periodic or regular care and monitoring to maintain their longevity and structural integrity. They are typically the most suitable for retaining and incorporating into the future landscape. Moderate: Applies to #2-7, 11, 13-15, 18-20, 22, 29, 36, 39, 41-43, 55, 57, 58, 62-64, 66, 67, 70, 73, 77-79, 81, 84, 86-93, 98-101, 103, 105, 108, 111, 114, 121, 122, 125, 129 and 133-135 and 138-147. These trees contribute to the site, but at levels less than those assigned a high suitability; might have health and/or structural issues which may or may not be reasonably addressed and properly mitigated; and frequent care is typically required for their remaining lifespan. They may be worth retaining, if provided proper care, but not seemingly at significant expense or major design revisions. Low: Applies to #1, 8-10, 21, 23-28, 30-33, 35, 37, 45, 46, 49, 51, 53, 54, 56, 59, 61, 65, 68, 69, 72, 74, 75, 80, 82, 95, 102, 106, 107, 109, 110, 112, 113, 115-120, 123, 124, 126- 128, 130-132, 136 and 137. These trees are either dead, dying or have serious or significantly weakened health and/or structural issues expected to worsen regardless of tree care measures employed (i.e. beyond likely recovery). Their removal is recommended regardless of future development, and in the case of trees #28, 49 and 123, they are dead.

The Oaks at Los Gatos ; 400 Blossom Hill Road, Los Gatos Swenson, San J ose Pa ge 7 of 18 David L. Babby, Registered Consulting Arborist® August 3, 201 8 5.0 APPRAISED TREE VALUES The monetary value of each tree planned for retention, 81 in total (refer to Section 4.0 for a listing), has been appraised to conform with Section 29.10.1000(c)(3a) of the Los Gatos Town Code. Individual values are listed within the last column of Exhibit A, and their combined total equals $271,740. Values were calculated using the Trunk Formula Method derived from the Guide for Plant Appraisal, <Jh Edition, 2000, and in conjunction with the Species Classification and Group Assignment, 2004 (published by the Western Chapter of the ISA). 6.0 TREE PROTECTION MEASURES Recommendations presented within this section consider plans reviewed, and serve as protection measures to help mitigate or avoid impacts to trees being retained, to include for both those inventoried and not inventoried for this report. They should be carefully followed and incorporated into project plans, and I (hereinafter "project arborist") should be consulted in the event any cannot be feasibly implemented. 6.1 Design Guidelines 1. The assigned Tree Protection Zone (TPZ) for each retained tree consists of the following prescribed setbacks (all distances intended to be obtained the closest edge , face of, their outer perimeter at soil grade): • #75 , 82 , 86 , 89 , 91. 92 , 93 , 98 , 107 . 110 , 119 , 126 and 129: 15 feet from their trunks up to 30 inches (or less) from back of wall and beyond in all directions. • #97: 30 feet from its trunk up to 30 inches (or less) from back of wall and beyond in all directions. • For all others: Within designated-fenced areas delineated and identified on the map in Exhibit B. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 8 of 18 David L. Babby, Registered Consulting Arborisf August 3, 2018 A TPZ is intended to restrict or highly limit the following activities within specified distances: overexcavation, subexcavation, trenching, compaction, mass and finish- grading, soil scraping, tilling, ripping, swales, bioswales, storm drains, dissipaters, equipment cleaning, stockpiling and dumping of materials, and equipment and vehicle operation. In the event an impact encroaches slightly within a setback, it can be reviewed on a case-by-case basis by the project arborist to determine whether measures can sufficiently mitigate the impacts to less-than-significant levels. 2. The retaining wall's shoring design should be designed and installed with no lateral overexcavation or other ground disturbance ( e.g. compaction and trenching); one possible method is shotcrete with soil nailing (nails driven at least 3 to 4 feet below ground and at a downward angle). Should this not be feasible, then overexcavation and other ground disturbance shall be confined to 30 inches from the back of wall , and tiebacks avoided or reviewed beforehand. Any fill placed beyond the wall (i .e. towards the trees) should be confined to 24 inches from the wall's edge. 3 . Recommendations for design revisions to lessen potential impacts are as follows: a. Relative to the existing 8-inch fire service line, add a note to Cl specifying its abandonment where within 25 feet from #97's trunk. b . Shift the proposed water line and meter away from #2's trunk for a 7-foot setback, which places the meter and line 5 feet from #1 '~ trunk. c. Shift the proposed drain line and biorention area north towards the space/area currently occupied by #21, and at distances of at least 30 feet from the trunks of #16 and 17. d. For #36, omit the two proposed parking spaces immediately north of its trunk, or increase setbacks from the trunk to accommodate a single parallel parking space there. Also, to the extent possible, reconfigure parking to allow enlarging the island 20 to 25 feet west of the trunk. In the event expansion of the island is not feasible in either direction, note the section of future parking lot within the TPZ, including the curb and gutter, will need building entirely above exposed ground and underlying base material, as well as avoiding soil compaction. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 9 of 18 David L. Babby, Registered Consulting Arboris/& August 3, 2018 e. Also for #36, to the extent possible, shift the proposed bioswale farther south to be 25 feet or more from the trunk. f. For #38 thru 40, shift the proposed lot away from the trunks to the extent possible, preferably by at least 15 or 20 plus feet. In areas where this is not possible, the lot, curb and gutter design within their TPZ will need to be built entirely above ground with no soil compaction. g. For #46, the proposed section of parking lot and storm drain line needs to be established entirely above the underlying surface of the existing lot ( or pulled away from the trunk to be beyond the tree's TPZ). 4. Constructing sections of parking lot above ground requires means and methods to minimize root loss and damage, while providing water permeability. To help accomplish this, all materials4 must be built on top of existing unpaved ground, or where applicable, on top of base material underlying the existing asphalt parking lot (i.e. a no-dig design), and the parking lot surface and base materials should be permeable. Suggestions for achieving these items are as follows: • Lay and pin down Tensar® BX Geogrid (www.tensarcorp.com) on existing, noncompacted ground or the base material surface underlying existing asphalt. • Depending on the final parking lot design, perforated, 3-inch diameter tubes are laid on the geogrid and across the entire section of parking lot, have risers on opposite sides of the parking lot, and space apart every 3 to 5 feet (tbd). • CU-Structural Soil™ is used for the base material and can be compacted (the local supplier is TMT Enterprises, www.tmtenterprises.net). • The parking lot surface should be permeable, such as permeable asphalt or pavers. • Any soil fill used to bevel the top of hardscape or curb to existing grade should be confined to 12 inches from the back of curb. • In the event constructing the parking lot requires removing any soil to achieve a particular depth for base material an AirSpade would be utilized, but will require direct supervision by the project arborist to ensure significant roots are retained (the size and amount of roots determined by the project arborist). 4 To include base materials , curb and gutter, edging and forms. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page JO of 18 David L. Babby , R egistered Consulting Arboris/' Augus t 3 , 2018 5. Coordinate sheets Al, A2, LS-1 and LS-3 with sheet Cl to respectively show all trees, assigned numbers, and designated removals. 6. Per Section 29.10.lOOO(C.l) of the Ordinance, a copy of this or a future report providing tree protection measures must be incorporated into the final set of project plans; titled Sheets T-1, T-2, etc. ("Tree Protection Instructions"); and referenced on all site-related project plans. Additionally, all site-related plans should contain notes referring to this report for tree protection measures. 7. On the demolition plan, specify to abandon all existing, unused lines or pipes within a TPZ, and any above-ground section shall be cut off at existing soil grade (rather than being dug up and causing subsequent root damage). 8. On the erosion control design , either by note and/or callout(s), specify any straw wattle or rolls shall require a maximum vertical soil cut of 2 inches for their embedment, and are established as close to canopy edges as possible (and not against a trunk). 9 . The permanent and temporary drainage design, including downspouts, should not require water being discharged towards a tree's trunk. 10 . A void specifying the use of herbicides use within a TPZ; where used on site, they should be labeled for safe use near trees. Also, liming shall not occur within 50 feet from a tree's canopy. 11 . Adhere to the following additional landscape guidelines: a. Plant material installed beneath the oak and buckeye canopies should be drought- tolerant, limited in amount, and placed at least 5 or more feet from their trunks. Plant material installed beneath canopies of all other trees should be at least 24 to 36 inches from their trunks. b. Introducing regular irrigation within the root zones of oaks and buckeyes can, overtime, impose adverse impacts and should be avoided. Rather, irrigation installed for new plant material beneath their canopies should be low-volume, applied irregularly (such as only once or twice per week), and temporary (such as The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 11 of 18 David L. Babby, Registered Consulting Arborist® August 3, 2018 <three years). Irrigation should not strike within 6 inches from the trunks of existing trees, and not applied against trunks of new trees. c. Establish irrigation and lighting features ( e.g. main line, lateral lines, valve boxes, wiring and controllers) to avoid trenching within a TPZ. In the event this is not feasible, route them in a radial direction to a tree's trunk, and terminate a specific distance from a trunk (versus crossing past it). In certain instances, an AirSpade may need to be used to avoid root damage, and any Netafim tubing used should be placed on grade, and header lines installed as mentioned above. Note that ultimately, routes shall be reviewed with the project arborist prior to any trenching or excavation occurring. d. Design any new site fencing or fence posts to be at least 2 to 5 feet from a tree's trunk ( depends on the trunk size, growth pattern and prior impacts). e. A void tilling, ripping and compaction within TPZs. f Establish any bender board or other edging material within TPZs to be on top of existing soil grade (such as by using vertical stakes). g. Utilize a 3-to 4-inch layer of coarse wood chips or other high-quality mulch for new ground cover beneath canopies (gorilla hair, bark or rock, stone, gravel, black plastic or other synthetic ground cover should be avoided). 6.2 Before Demolition, Grading and Construction 12. Continue or begin supplying water to the root zones of all trees being retained where any activities are planned beneath canopies, immediately or in the future. The methodology, frequency and amounts can be reviewed with the project arborist, possible methodologies including flooding the ground inside an 8-inch tall berm, soaker hoses, or deep-root injection. Note in the event dewatering is required for this project, the watering program shall be more intensive than otherwise needed (i.e. will require greater frequency and/or volume). 13. Stake the limits of grading, utility routes, retaining wall location, and parking lot/curb locations (whether all at once or various phases) for review by the project arborist prior to ground disturbance. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 12 of 18 David L. Babby, Registered Consulting Arborisl' August 3, 2018 14. Conduct a site meeting with the general contractor and project arborist several weeks or months prior to demolition for the purpose of reviewing protections measures presented in this report, such as tree fencing and trunk wrap protection, routes of access, staging, pruning, staking, watering, mulching, tree removals, etc. 15 . Prior to demolition, install tree protection fencing as shown on the map in Exhibit B; where along existing pavement or curbs, place within 6 to 12 inches from the edge. Fencing shall consist of 6-foot tall chain link mounted on 2-inch diameter, galvanized iron posts driven at least 2 feet into the ground, kept in place throughout construction, and removed or modified only under the knowledge and direct consent of the project arborist. Note fencing will require reconfiguration for several additional phases, such as grading, utility installation, retaining wall installation, building construction, etc. (all to be reviewed with the project arborist). 16. For fencing on existing asphalt areas, such as for #36 and 46 (see Exhibit B), panels placed on concrete blocks can alternatively be used, solely for the practical purpose of allowing those fenced areas to be opened during demolition of existing asphalt ( and also bringing attention to their TPZs, and the need to mitigate removal of the existing parking lot). 17 . Along with erecting protection fencing for the demolition phase, install trunk wrap protection for #36 and 46. This involves wrapping straw wattle horizontally around the trunks ( and for #46, also the low-originating southern limb), one section at the base and another at 10 to 12 feet high; placing four to six boards (2x4") vertically around the outside (and spaced apart), from the ground to 10 or 12 feet high; then wrapping orange-plastic fencing around the boards two to three times and tying together. For #36, also wrap five layers of orange-plastic fencing along the low limb over parking lot, from its union with the main trunk to 6 feet beyond. The wrap protection shall remain in place until directed otherwise by the project arborist. 18. Prior to demolition, affix and maintain 8.5-by 11-inch warning signs along each side of fencing opposite the trees' trunks (can be discussed with project arborist beforehand): "WARNING -Tree Protection Zone -this fence shall not be removed and is subject to penalty according to Town Code 29.10.1025." The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 13 of 18 David L. Babby, Registered Consulting Arborist® August 3, 2018 19 . Pruning of retained trees is needed prior to demolition and/or mobilizing heavy equipment to the site, and shall be highly selective, targeted, and performed under direction of the project arborist. Additionally, all work shall be conducted in accordance with the most recent ANSI A300 standards, and by a California state- licensed tree service contractor (D-49) that has an ISA certified arborist in a supervisory role, carries General Liability and Worker's Compensation insurance , and abides by ANSI Safety Operations. 20 . Prior to removing trees and the initial site meeting, paint an "X" on their trunks to allow review and confirmation with the project arborist. Removals shall be performed in a manner which does not damage trees being retained, and possibly contract a professional, state-licensed tree service to remove trees within designated- fenced areas prior to fencing being installed for the demolition phase (this can be discussed and reviewed further with the project arborist). 21. Establish the staging and cleanout area(s), as well as all routes of access beyond unpaved areas beneath tree canopies . Where challenges arise, review them beforehand with the project arborist to determine whether any measures can be employed to sufficiently mitigate the potential impacts. 22. Spread, and replenish as needed throughout the entire construction process, a 4-to 5- inch layer of coarse wood chips (V,i-to %-inch in size) from a tree-service company. 23. The removal of stumps, whether old or new, located within TPZs shall be performed with a stump grinder (versus being extracted with heavy equipment and inadvertently damaging roots of trees otherwise being retained). 24 . Where applicable, ivy should be cleared off and at least 5 feet from the trees' trunks ( or manually removed from planters altogether). 25. Also where applicable, clear soil to expose any buried root collars .5 This work must be manually and carefully performed to avoid damaging the trunk and roots during the process, and preferably by a tree-service company using an AirSpade to avoid unnecessary root and/or trunk damage . 5 A "root collar" is the distinct swollen area near the ground where buttress roots and the main trunk merge. The Oaks at Los Gato s; 400 Blossom Hill Road, Los Gatos Page 14 of 18 Swenson, San Jose David L. Babby, Registered Consulting Arborisf August 3, 2018 26. Fertilization may benefit a tree's health, vigor and appearance. If applied, however, soil samples should first be obtained to identify the pH levels and nutrient levels so a proper fertilization program can be established. I further recommend any fertilization is performed under the direction and supervision of a certified arborist, and in accordance with the most recent ANSI A300 Fertilization standards. 6.3 During Demolition, Grading and Construction 27. Any authorized access, digging or trenching within designated-fenced areas shall be by foot-traffic only, manually performed under supervision by the project arborist, and without the use of heavy equipment or tractors. 28. Take great care during demolition of existing hardscape and other equipment/features to avoid damaging a tree's trunk, canopy, soil and roots within a TPZ, including ground underlying existing features. Several items of particular note include removing the existing light pole and footing within #46's TPZ; the concrete rim for a manhole within #40's TPZ; and the old, large pile of spoils within #38's TPZ. 29. For parking lot demolition within the TPZs of #36 and 46, first remove only the asphalt surface, leaving base material intact, and where within three feet from the trunks of #36 and 46, remove using a crowbar ( or equivalent) to avoid gouging/damaging trunks during the process. Equipment used shall not operate or travel on unpaved ground, and removal of existing base material and roots 2:2 inches in diameter should only be performed under supervision of the project arborist; depending on rooting conditions, existing base may need to remain and be used for future base course material to avoid significant root loss. 30. Overexcavation and other soil disturbance for installing the new curb and gutter within 10 feet from # 15's trunk shall be confined to 6 inches from back of curb. 31. Great care must also be taken by equipment operators, including shoring operations, to position their equipment to avoid trunks and branches, including the scorching of foliage. Any tree damage or injury should be reported to the project arborist for review of treatment. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 15 of 18 David L. Babby, Registered Consulting Arborist® August 3, 2018 32. Avoid using tree trunks as winch supports for moving or lifting heavy loads, as well as for tying rope, cables, chains or other items around. 33. Spoils created during digging shall not be piled or spread on unpaved ground within a TPZ. If essential, spoils can be temporarily piled on plywood or a tarp. 34. Prior to installing shoring and excavating for the retaining wall surrounding the building, manually excavate a 1-foot wide trench along the perimeter of where soil excavation will occur closest to the a tree's trunk for the following distances: 30 feet from #97's trunk, and 15 feet from the trunks of trees #75, 82, 86, 89, 91-93, 98, 107, 110, 119, 126, 129 (the purpose is to avoid roots breaking and being damaged closer to the trunk than otherwise needed). Excavation should occur down to a 36-inch depth, and all roots encountered during the process with diameters 2:2 inches shall be cleanly severed by hand using a new and sharp handsaw and/or loppers at 90° to the direction of root growth against the tree side of the trench. All soil beyond the trench (i.e. away from the tree) can then be mechanically excavated using heavy equipment, and remaining outside the fenced area(s). Alternatively, the use of a stump grinder could be utilized precisely where a curb/gutter and any overcut (12" max) will be established. Advise the project arborist when this work is scheduled so observations of cut roots can be made. Exposed roots surfaces should be kept continually moist, perhaps by draping burlap over the cut face and applying water daily or twice daily. 35. Avoid damaging or cutting roots with diameters of 2:2 inches without pnor assessment by the project arborist. Should roots of this size be encountered, within one hour of exposure, they should either be covered by burlap that remains continually moist until the root is covered by soil. If they are approved for cutting, cleanly severe at 90° to the angle of root growth against the cut line (using loppers or a sharp hand saw), and then immediately after, the cut end either buried with soil or covered by a plastic sandwich bag (and secured using a rubber band, and removed just before backfilling). Roots encountered with diameters <2 inches and requiring removal can be cleanly severed at right angles to the direction of root growth. The Oaks at Los Gatos; 400 Blossom Hill Road, Los Gatos Swenson, San Jose Page 16 of 18 David L. Babby, Registered Consulting Arborist® August 3, 2018 36. Digging holes for fence posts within a TPZ shall be manually performed using a post-hole digger, and in the event a root ~2 inches in diameter is encountered during the process, the hole should be shifted over by 12 inches and the process repeated. 37 . Dust accumulating on trunks and canopies during dry weather periods may need to be periodically washed away if directed by the project arborist (e.g. every 4 months). 38. Avoid disposing harmful products (such as cement, paint, chemicals, oil and gasoline) beneath canopies or anywhere on site that allows drainage within or near TPZs. Herbicides should not be used with a TPZ; where used on site, they should be labeled for safe use near trees. A void liming within 50 feet of a tree's canopy .
