The lot is approximately 29 ,000 square feet (24,500 net square feet) with a 1 ,953-square foot single-story residence and a 660 -square foot detached garage. The residence was effectively demolished by a prior property owner in that all of the exterior siding and interior sheetrock were removed. The house has been vacant for a number of years . The project is being forwarded to the Planning Commission because the project would result in the largest house in the immediate area. PROJECT DESCRIPTION: A. Architecture and Site Application The applicant is proposing a 4,428-square foot single-story residence with a 1 ,008-square foot garage. The project would have a maximum height of23 feet, 11.5 inches . The proposed materials include: stucco siding, stone veneer, stone and wood trim, true divided lite wood windows, and a mission tile roof. A color and material board will be available at the Planning Commission meeting, and Exhibit 4 includes general project data. B. Location and Surrounding Neighborhood The project site is located at the southern terminus of the northern portion of Camino Del Cerro. Ross Creek runs along the southern border of the property and Camino Del Cerro continues to the south of Ross Creek (Exhibit 1 ). Surrounding properties contain single- family residences. C. Zoning Compliance The proposed project complies with the height and structure coverage limitations. The proposed project complies with setback requirements and all required parking is being provided on-site. The zoning permits a single-family residence. ANALYSIS: A. Floor Area Based on Town and County records, the residences in the immediate area range in size from 1,100 square feet to 3,304 square feet. The floor area ratios (FAR) range from 0. I 3 FAR to 0.37 FAR. The proposed residence would be 4 ,428 square feet with a 0.18 FAR. Pursuant to Town Code, the maximum sq uare footage for the lot size is 4 , 753 square feet.

The project was referred to the Planning Commission because it would result in the larges t residence in the immediate are a. T he proposed residence would be significantly larger than tho se in the immediate area. The Residential Design Guidelines specify that residential development shall be similar in mass, bulk, and scale to the immediate neighborhood. The Guidelines also specify that consideration will be given to the existing F ARs, residential square footages , and lot si z es in the neighborhood . The applicant provides justification for the proposed residence in Exhibit 5 . Even though the property is significantly larger, has limited visibility from the rear yards of the adjacent residences, and does not contribute to any adjacent streetscape, staff Planning Commission Staff Report -Page 5 15735 Camino Del Cerro/S-15-063 December 9, 2015 recommends denial because the proposed home would be 1, 1 00 square feet larger than the largest home in the immediate area . B. Tree Impacts The project site contains 27 trees (onsite and adjacent); 24 are protected trees and three are fruit or nut trees less than 12 inches in diameter. The applicant is proposing to remove 13 trees, ten of which are protected. The majority of the protected trees proposed for removal are large fruit or nut trees , but also include an 84-inch Blue Gum Eucalyptus, and a 30-inch Willow . The applicant provided an Arborist report for the site (Exhibit 6) which was reviewed by the Town's Consulting Arborist (Exhibits 7 and 8). The applicant 's arborist incorporated the recommended changes from the Consulting Arborist into the applicant's final arborist report (Exhibit 9). If the project is approved , tree protection measures would be implemented prior to and during construction. Replacement trees would be required to be planted pursuant to Town Code. Tree protection measures are incorporated as conditions of approval (Exhibit 3) to protect the trees to remain on the subject property and within the development area. C. Creek Setback The applicant is proposing a 15-foot setback from the top of bank, adjacent to the stream channel. The proposed setback conforms to the Guidelines and Standards for Land Use Near Streams which specify a 15-foot setback for streams contained in a concrete channel. All proposed improvements will be located outside the 15-foot setback (see Condition# I 0 in Exhibit 3). D. Architectural Considerations Staff requested that the Town 's Architectural Consultant review the project (Exhibit 1 0) to provide recommendations regarding architecture and neighborhood compatibility. The consultant identified several recommended changes in order to bring the project into compliance with the Town's Residential Design Guidelines (Exhibit 11). The applicant made several changes to address the Consultant's recommendations and staff forwarded the revi s ions to the consultant for a second review (Exhibit 12). The second review by the Consultant had the following recommendations: 1. Go back to the partial gable end on the right side elevation and symmetrically mirror the partial gable on the left side of that main roof to provide a more balanced design. 2. Do something with the skylight structure. It is bulky and the stucco would stand in strong contrast to the slate roofing. A more refined form would be desirable. Planning Commission Staff Report -Page 6 15735 Camino Del Cerro/S-15-063 December 9, 2015 Based on direction from the Consulting Architect and staff, the applicant made changes to simplify the massing of the roof and incorporated a flat skylight rather than the projecting skylight as originally proposed. The revisions are incorporated into the final development plans included in Exhibit 13. E. Environmental Review The project is Categorically Exempt pursuant to the adopted Guidelines for the Implementation of California Environmental Quality Act, Section 15303: New Construction or Conversion of Small Structures. PUBLIC COMMENTS: At this time , the Town has not received any public comment. The applicant has informed staff that they have met with the majority of the adjacent neighbors. SUMMARY AND RECOMMENDATION : A. Summary As currently proposed, the project would create a residence that is approximately I , I 00 square feet larger than the largest home in the immediate area. The applicant has worked with staff to address architectural concerns and to maintain the recommended setback from the creek. The property is well screened by existing vegetation and will have limited visibility from adjacent residences . B. Recommendation Staff recommends denial of the Architecture and Site application based on the size of the residence in comparison to those in the immediate area. Alternatively, the Commission could : 1. Approve the application by taking the following actions: a. Find that the proposed project is categorically exempt, pursuant to Section 15303 of the California Environmental Quality Act as adopted by the Town (Exhibit 2); and b. Make the required findings as required by Section 29.10.09030(e) ofthe Town Code for granting approval of a demolition of a single-family residence (Exhibit 2); and c. Make the finding that the project complies with the Residential Design Guidelines (Exhibit 2); and Planning Commission Staff Report -Page 7 15735 Camino Del Cerro/S-15-063 December 9, 2015 d. Make the required considerations as required by Section 29.20.150 of the Town Code for granting approval of an Architecture & Site application (Exhibit 2); and e. Approve Architecture and Site Application S-15-063 with the conditions contained in Exhibit 3 and development plans attached as Exhibit 13 . 2. Approve the application with additional and/or modified conditions. 3. Continue the matter to a date certain with specific direction. B epared by: ' am1 F.

Neighborhood Characteristics: RECEIVED NO V 1 1 ?015 TOVVN OF LOS GATOS PLANtJING UIVISION November 11 TH. 2015 The "Immediate Neighborhood" comprises either 16 immediate neighbors, plus townhomes across the street; or none-as this property is isolated from the immed iate neighborhood by a long driveway and is over 350 ft from the street. If you consider the 16 neighbors, there are 1960's single story homes [one with a second story addition] on one street at the rear; 1980's predominately 2 story homes that adjoin the right side of the property; and 1990's 1t and 2 story homes immediately across the creek. There is no predom inant styling, What does appear to be consistent in the neighborhood is a consistent lot s ize of between 8 ,000 and 11 ,000 square feet. On the street behind [1960's neighborhood] the mainly single story homes exhibit large accessory buildings in the back yard . but these smaller homes have FARs in the 13-21% range. On the street to the right [north] of the property [the 1980's neighborhood] these 2 ,500-3 ,000 sq ft houses have FARs in the 25-30/'o range. Across the creek [the 1990's neighborhood] there are larger 2 story houses, up to 3 ,300 sq ft . on 9 ,000 sq ft lots exhibiting FARs between 30-37/'o. In contrast, th is lot is 2/3 acre and any house built on it will not be seen from Camino del Cerro. We have deducted the driveway for a Net Lot Size Of 24 ,500 square feet and an allowable 4 ,753 ft house. We are proposing 4,428 with an FAR of 18/'o. Max height will be 23ft 11 t ". Design Influences : The houses to the north and west share common fences with 15735 Camino Del Cerro; but that is about all they share. They are elevated 3-4 ft higher and the bottom 10 ft of any structures built there will never be seen by these neighbors. We have chosen to build a single story home, and to slope the roof away from the property line with a hipped roof so that our project will not impact them once it is built . We chose a 2-piece mission tile roof over slate because it is more compat ible with other homes in the area. We are fully aware that we are a "flag lot" as viewed from these homes and are trying to mitigate any s ight , light. view-shed and privacy issues. The homes across the creek on Sierra Morena Court wil l be more impacted by any development on 15735 Camino Del Cerro as this is the view they will see every day as they come and go e ither by car or by foo t t o or from their homes . Again , a single story home will be less impactful than will be a 2 story home and the 2/3 acre lot size will readily accommodate it. Ultimately we chose to design a home with stucco and stone exterior , borrowing from the homes across the creek, and the contemporary ranch style exterior with the slate roof seemed more appropriate than traditional Mediterranean. Stone was incorporated into the design to break up the stucco appearance. All said and done , the owners are happy with the overall concept . i£x.H.w1 r s This Page Intentionally Left Blank The Project: Our clients have 3 chi ldre n and have f requent visitors who stay for brief periods, so they want a 5 bedroom home plus office. The key for them is an indoor/outdoor entertaining area with plenty of light so we have incorporated a commercial grade sky light to bring light into t he center of the home . A cabana and pool in the rear ya r d will be well scr e ened from the ne ighbors . Solar Photovol t a ic pan e ls are proposed at the roof of the cabana and co vered patios [invisible from neighbors] are proposed . The existing partially deconstructed home on the property is not economi cally viable to reta in as a base for th is project and would requ ire a technica l demolition in any event. Driveway, Grading & Drainage : The preliminary Grading Plan shows min imal grading; ther e is no Import or Export proposed. There are no significant grade changes-except to convey water runoff to Camino Del Cerro at the request of SCVWD , rather than allowing it to sheet-flow over the banks of Ross Creek. Dissipaters and splash -blocks will be used. Because this is a flag lot with a depth of over 500 ft we have designed a Fire Truck Turnaround into the driveway , wh ich will be a combination of Pavers and asphalt. There will be a curb along the creek s ide of the driveway. Trees and Landscaping: Six trees , which fall under the category of "Protected Trees", are planned for removal, but none is considered a s ignificant contributor. Any replacement trees will conform to the new Town Tree Ordinance. They will be native and drought tolerant, but the species have yet to be finalized . Three are specifically denoted as Redwoods to replace the large Eucalyptus which is being removed . Screening trees will be placed along the right side and rear property lines, but ongo ing discussions with neighbors will determine species. In this Application we are proposing a total of 24 replacement trees and 4 fruit t r ees . Drought tolerant vegetation is proposed project design , together with either decomposed granite or synthetic permeable turf in the rear yard. Only drip irrigation will be used for landscape irrigat ion. Please call me at 408-354-1833 if you have any questions. Yours truly, T.H.I.S. Design & Devel opment per: A. T.

( 15735 Camino Del Cerro Tree Inventory, Assessment, and Protection Plan August4,2015 Summary The property located at the end of Camino Del Cerro and adjacent properties contain twenty- seven trees comprised of eleven different species. The most commonly found species in the inventory is coast live oak (Quercus agrifolia), most of which are located adjacent to the driveway along the top of the creek bank. The blue gum eucalyptus (Eucalyptus g/obulus) (887) is the only tree considered a "Large Protected Tree" as defmed in section 29.10.0955 Defmitions of the municipal code. Most of the trees are in either fair or good condition with fair or good suitability for preservation. Eleven trees will be highly affected by the project, four of which are not protected by the ordinance. The trees growing along the top of the creek bank will not be affected depending on the new driveway construction. The removal of seven protected trees will result in a replanting mitigation plan to account for lost canopy cover. Introduction Background Tony Jeans ofT.H.I.S. Design asked me to assess the site, trees, proposed footprint plan, and to provide a report with my fmdings and recommendations to help satisfy the Town of Los Gatos planning requirements . Assignment 1. Provide an arborist's report that includes an assessment of the trees within the project area. The assessment is to include the species, size (trunk diameter), condition (health and structure), and suitability for preservation ratings. 2. Provide tree protection specifications and influence ratings for the trees that will be influenced by the project. 3. Provide canopy replacement requirements. Limits of the assignment 1. The information in this report is limited to the condition of the trees during my inspection on July 31,2015. No tree risk assessments were performed. 2. The plans reviewed for this assignment were as follows: Site Plan C2 and Grading and Drainage Plan C3 dated July 2015. No landscape or utility plan was reviewed.

The report is to be used by T.H.I.S. Design, the property owners, their agents, and the Town of Los Gatos as a reference for existing tree conditions to help satisfy the Town of Los Gatos planning requirements. Observations The property is a flag lot located at the end of Camino Del Cerro if you enter from the Los Gatos Almaden Road intersection (Image 1 ). The property is the last lot on the west side of the road where Ross Creek bisects Camino Del Cerro at the foot bridge. The lot and adjacent properties contain twenty-seven trees on or in close proximity to the property. Most of the trees are coast live oaks located along the driveway into the main portion of the property and are growing at the top of the creek bank on the other side of the cyclone fence. Within the property are three silk trees (Albiziajulibrissin), a black walnut (Juglans nigra), willow, a few fruit trees and one large blue gum eucalyptus. The north side of the driveway is lined with oleander (Nerium oleander) growing under the high voltage utility lines. The proposed new structure moved the main house east toward the central portion of the lot creating a larger backyard. The new structure footprint is over the two silk trees and orange. The plan indicates a total of twenty-two 24-inch box and five 15-gallon replacement trees are to be planted around the site.

The Town of Los Gatos protects all trees with a trunk diameter greater than (4) four inches at (54) fifty-four inches above grade on vacant or underdeveloped lots (Appendix A and B). Aluminum tree tags have been affixed to all trees listed in the inventory except the two trees on the adjacent properties. The property and adjacent properties contain twenty-seven trees comprised of eleven different species. The most commonly found species in the inventory is coast live oak, most of which are located adjacent to the driveway along the top of the creek bank. The trees within the property consist of the black walnut (889), blue gum eucalyptus (887), three silk (892, 893, and 895), with one willow (894) growing horizontal off the retaining wall, as well as some smaller trees (888, 890, 891, and 896). The blue gum eucalyptus (887) is considered a "Large Protected Tree" as defmed in section 29.10.0955 Definitions of the municipal'code.

The assessment considered both the health and structure of the trees for a combined condition rating. • Exceptional = Good health and structure with significant size, location or quality. • Good = No apparent problems, good structure and health, good longevity for the site. • Fair = Minor problems, at least one structural defect or health concern, problems can be mitigated through cultural practices such as pruning or a plant health care program. • Poor= Major problems with multiple structural defects or declining health, not a good candidate for retention. • Dead/Unstable = Extreme problems, irreversible decline, failing structure, or dead. Most of the trees are in either fair or good condition, primarily because they are small volunteers that have not developed the same kinds of problems older trees develop. The willow (894) and silk (895) are both in poor shape and located along the north side of the driveway within the oleander hedge.

The following list defmes the rating scale (Tree Care Industry Association, 2012): • Good = Trees with good health, structural stability and longevity. • Fair = Trees with fair health and/or structural defects that may be mitigated through treatment. These trees require more intense management and monitoring, and may have shorter life spans than those in the good category. • Poor = Trees in poor health with significant structural defects that cannot be mitigated and will continue to decline regardless of treatment. The species or individual may possess characteristics that are incompatible or undesirable in landscape settings or unsuited for the intended use of the site. Most of the trees have fair or good suitability for preservation and are small volunteers growing along the top of the creek bank adjacent to the existing driveway. In addition to the silk (895) and willow (894) I also considered the almond (885), black walnut (881) although it is on water district property, mock orange (896), and the blue gum eucalyptus (887) to be poorly suited for preservation. The black walnut (889) has fair suitability for preservation but the area near the tree would need to be left alone because the tree's tolerance to disturbance is poor.

The following scale defines the impact rating: • Low = The construction activity will have little influence on the tree. • Moderate = The construction may cause future health or structural problems, and steps must be taken to protect the tree to reduce future problems. • High = Tree structure and health will be compromised and removal is recommended , or other actions must be taken for the tree to remain. The tree is located in the building envelope. Eleven trees will be highly affected by the project, four of which are not protected by the ordinance. The trees highly influenced are all the fruit trees and mock orange along with the three silk, black walnut (889), willow (894), and blue gum eucalyptus (887). The trees growing along the top of the creek bank will not be affected depending on the new driveway construction.

The tree protection zone (TPZ) is the defined area in which certain activities are prohibited to minimize potential injury to the tree . The TPZ can be detennined by a formula based on species tolerance, tree age, and diameter at breast height (DBH) (Matheny, N. and Clark, J . 1998) or as the drip line in some instances. The tree protection zones for this project should be located at the critical root zone distance of five times the trunk diameter because influence will only be on one side of any tree to remain. The fence along the driveway should remaining place during construction unless a new fence is to be erected prior to construction. This will protect the trees on the adjacent site and is a sufficient means of Type I tree protection. Preventing mechanical damage to the main stems from equipment or hand tools can be accomplished by wrapping the main stem with straw wattle for Type II and Type III protection scenarios (Figure 2). The wattle will create a porous barrier around the trunk and prevent damage to the bark and vascular tissues underneath. No trees for this project will require trunk protection.

The critical root zone (CRZ) is the area of soil around the trunk of a tree where roots are located that provide stability and uptake of water and nutrients required for the tree's survival. The CRZ is the minimum distance from the trunk that trenching or root cutting can occur and will be defined by the trunk diameter as a distance of three times the DBH in feet , and preferably, five times (Smiley, E .T., Fraedrich, B. and Hendrickson, N. 2007). For example if the tree is two feet in diameter, the minimum CRZ distance would be six to ten feet from the stem on one side of the tree. The recommended maximum encroachment distance into the root zone of oaks on one side is five times the trunk diameter (Coate, B.)(Costello, L., Hagan, B., Jones, K. 2011)(Figure 3). Most of the trees that could be affected are located along the driveway at the top of the creek bank. New driveway construction will be the only impact on the trees. Critical Root Zone (CRZ) = 5 times the trunk diameter for California oak trees . Preferred 4 5x Figure 3: The image above depicts the preferred Critical Root Zone distance for oaks.

The most commonly found species in the inventory is coast live oak, most of which are located adjacent to the driveway along the top of the creek bank. The blue gum eucalyptus (887) is the only tree considered a "Large Protected Tree" as defined in section 29.10.0955 Defmitions ofthe municipal code. Most ofthe trees are in either fair or good condition, primarily because they are small volunteers that have not developed the same kinds of problems older trees develop. The willow (894) and silk (895) are both in poor shape and located along the north side of the driveway within the oleander hedge. The majority of trees have fair or good suitability for preservation and are small volunteers growing along the top of the creek bank adjacent to the existing driveway. In addition to the silk (895) and willow (894) I also considered the almond (885), black walnut (881) although it is on water district property, mock orange (896), and the blue gum eucalyptus (887) to be poorly suited for preservation. Eleven trees will be highly affected by the project, four of which are not protected by the ordinance. The trees highly influenced are all the fruit trees and mock orange a long with the three silk, black walnut (889), willow (894), and blue gum eucalyptus (887). The trees growing along the top of the creek bank will not be affected depending on the new driveway construction. The fence along the driveway should remaining place during construction unless a new fence is to be erected prior to construction. This will protect the trees on the adjacent site. Most of the trees that could be affected are located along the driveway at the top of the creek bank. The removal of seven protected trees will result in a replanting mitigation plan to account for lost canopy cover. A total of twenty-five 24-inch box or a combination of five to seven 36-inch box in addition to ten or fourteen 24-inch specimens or would be required. The current plan indicates a total oftwenty-two 24-inch box and five 15- gallon replacement trees are to be planted around the site. Recommendations 1. Obtain all necessary permits prior to removing or significantly altering any trees. 2. Provide a replanting plant with the appropriate number and size of trees or mitigate the loss in canopy cover (Appendix F). 3. Maintain the current fence along the driveway to be used as tree protection or construct a new one prior to site development activity to be used as a Type I tree protection fence. 4 . Construct the driveway out of porous materials and do not cut into the soil surface for sub- base treatment. Place new driveway on top of existing grade.

In trees defects are injuries, growth patterns, decay, or other conditions that reduce the tree's structural strength. Diameter at breast height (DBH): Measures at 1.4 meters (4 .5 feet) above ground in the United States, Australia (arboriculture), New Zealand, and when using the Guide for Plant Appraisal, 9th edition; at 1.3 meters (4.3 feet) above ground in Australia (forestry), Canada, the European Union, and in UK forestry ; and at 1.5 meters (5 feet) above ground in UK arboriculture. Drip Line: Imaginary line defmed by the branch spread or a single plant or group of plants. Mechanical damage: Physical damage caused by outside forces such as cutting, chopping or any mechanized device that may strike the tree trunk, roots or branches. Scaffold branches: Permanent or structural branches that for the scaffold architecture or structure of a tree. Straw wattle: also known as straw worms, bio-logs, straw noodles, or straw tubes are man made cylinders of compressed, weed free straw (wheat or rice), 8 to 12 inches in diameter and 20 to 25 feet long. They are encased in jute, nylon, or other photo degradable materials, and have an average weight of 35 pounds . Tree Protection Zone (TPZ): Defmed area within which certain activities are prohibited or restricted to prevent or minimize potential injury to designated trees, especially during construction or development. Tree Risk Assessment: Process of evaluating what unexpected things could happen, how likely it is , and what the likely outcomes are. In tree management, the systematic process to determine the level of risk posed by a tree, tree part, or group of trees. Trunk: Stem of a tree. Volunteer: A tree, not planted by human hands, that begins to grow on residential or commercial property. Unlike trees that are brought in and installed on property, volunteer trees usually spring up on their own from seeds placed onto the ground by natural causes or accidental transport by people. Normally, volunteer trees are considered weeds and removed, but many desirable and attractive specimens have gone on to become permanent residents on many public and private grounds.

Size and materials: Six (6) foot high chain link fencing , mounted on two-inch diameter galvanized iron posts, shall be driven into the ground to a depth of at least two (2) feet at no more than ten-foot spacing. For paving area that will not be demolished and when stipulated in a tree preservation plan, posts may be supported by a concrete base. 2 . Area type to be fenced: Type I : Enclosure with chain link fencing of either the entire dripline area or at the tree protection zone (TPZ), when specified by a certified or consulting arborist. Type II: Enclosure for street trees located in a planter strip: chain link fence around the entire planter strip to the outer branches. Type III: Protection for a tree located in a small planter cutout only (such as downtown): orange plastic fencing shall be wrapped around the trunk from the ground to the frrst branch with two-inch wooden boards bound securely on the outside. Caution shall be used to avoid damaging any bark or branches. 3. Duration of Type I, II, III fencing: Fencing shall be erected before demolition, grading or construction permits are issued and remain in place until the work is completed. Contractor shall frrst obtain the approval of the project arborist on record prior to removing a tree protection fence. 4. Warning Sign: Each tree fence shall have prominently displayed an eight and one-half-inch by eleven-inch sign stating: "Warning-Tree Protection Zone-This fence shall not be removed and is subject to penalty according to Town Code 29.10.1025." Text on the signs should be in both English and Spanish (Appendix E). All persons, shall comply with the following precautions 1. Prior to the commencement of construction, install the fence at the dripline, or tree protection zone (TPZ) when specified in an approved arborist report, around any tree and/or vegetation to be retained which could be affected by the construction and prohibit any storage of construction materials or other materials, equipment cleaning, or parking of vehicles within the TPZ. The dripline shall not be altered in any way so as to increase the encroachment of the construction. 2. Prohibit all construction activities within the TPZ, including but not limited to: excavation, grading, drainage and leveling within the drip line of the tree unless approved by the Director. 3 . Prohibit disposal or depositing of oil, gasoline, chemicals or other harmful materials within the drip line of or in drainage channels, swales or areas that may lead to the drip line of a protected tree . 4 . Prohibit the attachment of wires, signs or ropes to any protected tree. 5 . Design utility services and irrigation lines to be located outside of the dripline when feasible.

Retain the services of a certified or consulting arborist who shall serve as the project arborist for periodic monitoring of the project site and the health of those trees to be preserved. The project arborist shall be present whenever activities occur which may pose a potential threat to the health of the trees to be preserved and shall document all site visits. 7 . The Director and project arborist shall be notified of any damage that occurs to a protec ted tree during construction so that proper treatment may be administered. Listed below are some additional tree protection measures: Monitoring Any trenching, construction or demolition that is expected to damage or encounter tree roots should be monitored by the project arborist or a qualified ISA Certified Arborist and should be documented. The site should be evaluated by the project arborist or a qualified ISA Certified Arborist after construction is complete, and any necessary remedial work that needs to be performed should be noted. Root Pruning Roots greater than two inches in diameter shall not be cut. When roots over two inches in diameter are encountered and are authorized to be cut or removed, they should be pruned by hand with loppers, handsaw, reciprocating saw, or chain saw rather than left crushed or torn. Roots should be cut beyond sinker roots or outside root branch junctions and be supervised by the project arborist. When completed, exposed roots should be kept moist with burlap or backfilled within one hour. Boring or Tunneling Boring machines should be set up outside the drip line or established Tree Protection Zone. Boring may also be performed by digging a trench on both sides of the tree until roots one inch in diameter are encountered and then hand dug or excavated with an Air Spade® or similar air or water excavation tool. Bore holes should be adjacent to the trunk and never go directly under the main stem to avoid oblique (heart) roots. Bore holes should be a minimum of three feet deep. Tree Pruning and Removal Operations All tree pruning or removals should be performed by a qualified arborist with a C-61/D-49 California Contractors License . Treatment, including pruning, shall be specified according to ANSI A-300A standards and limitations and performed according to ISA Best Management Practices, and adhere to ANSI Z133.1 safety standards. Trees that need to be removed or pruned should be identified in the pre-construction walk through. ~' Monarch Consulting Arborists LLC -P.O Box 1010, Felton, CA 95018 831 .331 .8982-rick@monarcharborist.com Page 24 of 29 .r I 15735 Camino Del Cerro Tree Inventory, Assessment , and Protection Plan Appendix E: Tree Protection Signs E1:English Cl) r:: 0 N C)c: c: .2 ·-... c (.) ....
