The inventory contains 13 trees comprised of 8 different species with no Large Protected, seven Protected, and three Exempt while the remaining trees are less than twelve inches in diameter originating on the adjacent sites. Most of the trees are in fair condition and two have fair suitability for preservation. All four trees originating on the site will be highly impacted and caused to be removed which are Japanese maple #136, Sweetgum #137, pear #138 and apple #139. The trees on the adjacent sites are not expected to be highly impacted by the project depending on the grading and drainage plans. Replacement trees will be required and tree protection for this project would consist of a fence at the property setbacks or close to them on the north and west side of the property. A total of 13 trees were appraised for a rounded depreciated value of $26,350.00 using the Trunk Formula Method. Introduction Background The Town of Los Gatos asked me to assess the site, trees, and proposed footprint plan, and to provide a report with my findings and recommendations to help satisfy planning requirements. Assignment •Provide an arborist’s report including an assessment of the trees within the project area and on the adjacent sites. The assessment is to include the species, size (trunk diameter), condition (health and structure), and suitability for preservation ratings. Affix aluminum number tags on the trees for reference on site and on plans. •Provide tree protection specifications, guidelines, and impact ratings for trees that may be affected by the project. •Provide appraised values. Limits of the assignment •The information in this report is limited to the condition of the trees during my inspection on May 20, 2019. No tree risk assessments were performed. •Tree heights and canopy diameters are estimates. •The most recent Guide to Plant Appraisal, Tenth Edition was published in late 2018 by the ISA. The Guide is not functional at this time due to significant errors in the original printed version and gaps in information regarding regional species characteristics and nursery stock wholesale costs. Therefore the ninth edition and its supplemental publications were used for this assignment with the exception of the “condition ratings” assessment.

Purpose and use of the report The report is intended to identify all the trees within the plan area that could be affected by a project. The report is to be used by the Town of Los Gatos and the property owners as a reference for existing tree conditions to help satisfy planning requirements. Observations The plans indicate the existing structure will be demolished and a new residence constructed. Tree Inventory The inventory consists of trees protected by the Town of Los Gatos located on site and those in close proximity on neighboring properties. Sec. 29.10.0960. - Scope of protected trees. All trees which have a four-inch or greater diameter (twelve and one half-inch circumference) of any trunk, when removal relates to any review for which zoning approval or subdivision approval is required. (Appendix A and B). Los Gatos Town Ordinance 29.10.0970 Exceptions (1) states the following: “A fruit or nut tree that is less than eighteen (18) inches in diameter (fifty-seven-inch circumference).   Table 1: Plans Reviewed Checklist Plan Date Sheet Reviewed Source Existing Site Topographic Map or A.L.T.A with tree locations Proposed Site Plan 4/9/19 A1 Yes RH Associates Architects Demolition Plan Construction Staging Grading and Drainage Utility Plan and Hook- up locations Exterior Elevations Landscape Plan Irrigation Plan T-1 Tree Protection Plan Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 2 25 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 The inventory contains 13 trees comprised of 8 different species. No trees are Large Protected , seven are Protected , and three are 1 2 Exempt while the remaining trees are less than twelve inches in diameter they originate on the adjacent sites. The chart below list 3 the species and their relative quantities (Chart 1).   Large protected tree means any oak (Quercus spp.), California buckeye (Aesculus californica), or Paciﬁc madrone (Arbutus menziesii) which has a 24-inch or 1 greater diameter (75-inch circumference); or any other species of tree with a 48-inch or greater diameter (150-inch circumference). Protected tree means a tree regulated by the Town of Los Gatos as set forth in Section. 29.10.0960, Scope of protected trees.2 A fruit or nut tree that is less than eighteen (18) inches in diameter (ﬁfty-seven-inch circumference).3 Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 3 25 Quantity 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Analysis Tree appraisal was performed according to the Council of Tree & Landscape Appraisers Guide for Plant Appraisal 9th Edition, 2000 (CLTA) along with Western Chapter International Society of Arboriculture Species Classification and Group Assignment, 2004. The trees were appraised using the “Cost Approach” and more specifically the “Trunk Formula Method” (Appendix B). “Trunk Formula Method” is calculated as follows: Basic Tree Cost = (Appraised tree trunk increase X Unit tree cost + Installed tree cost) Appraised Value = (Basic tree cost X Species % X Condition % X Location %). The trunk formula valuations are based on four tree factors; species, size (trunk cross sectional area), condition, and location. There are two steps to determine the overall value. The first step is to determine the “Basic Tree Cost” based on size and species rating which is determined by the Species Classification and Group Assignment, 2004 Western Chapter Regional Supplement. The second part is to depreciate the value according to the location and condition of the trees. The condition assessment and percentages are defined in the “Condition Rating” section of this report. The condition ratings deviate from the Guide’s condition assessment numerical rating system. The reason for this deviation is the Guide’s assessment criteria fails to account for significant health or structural issues creating high percentages for tree with either significant structural defects or health problems that could ultimately lead to failure or irreversible decline. Location rating is an average of three factors; site, contribution, and placement. Site is determined by the relative property value where the trees are planted. The residential site would be classified as “very high” value with a 90 percent rating compared to similar sites in the area (ISA, 2000). Contribution and placement is determined by the function and aesthetics the trees provide for the site and their location on the property. The percent of contribution and placement can range from 10 to 100 percent depending on the trees influence to the value of the property. These percentages ranged from 0 to 90 percent in my assessment. A total of 13 trees were appraised for a rounded depreciated value of $26,350.00 using the Trunk Formula Method (Appendix B).  Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 4 25 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Discussion Condition Rating A tree’s condition is a determination of its overall health, structure, and form. The assessment considered both the health and structure for a combined condition rating. •100% - Exceptional = Good health and structure with significant size, location or quality. •61-80% - Good = Normal vigor, well-developed structure, function and aesthetics not compromised with good longevity for the site. •41-60 % - Fair = Reduced vigor, damage, dieback, or pest problems, at least one significant structural problem or multiple moderate defects requiring treatment. Major asymmetry or deviation from the species normal habit, function and aesthetics compromised. •21-40% - Poor = Unhealthy and declining appearance with poor vigor, abnormal foliar color, size or density with potential irreversible decline. One serious structural defect or multiple significant defects that cannot be corrected and failure may occur at any time. Significant asymmetry and compromised aesthetics and intended use. •6-20% - Very Poor = Poor vigor and dying with little foliage in irreversible decline. Severe defects with the likelihood of failure being probable or imminent. Aesthetically poor with little or no function in the landscape. •0-5% - Dead/Unstable = Dead or imminently ready to fail. Most of the trees are in fair condition with four good, eight fair, and one in poor shape (Chart 2).   Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 5 25 Quantity 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Suitability for Preservation A tree’s suitability for conservation is determined based on its health, structure, age, species and disturbance tolerances, proximity to cutting and filling, proximity to construction or demolition, and potential longevity using a scale of good, fair, or poor (Fite, K, and Smiley, E. T., 2016). Trees with good suitability have good vigor, structural stability, and potential longevity after construction. •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. Two trees have fair suitability for preservation which are the Japanese maple and sweetgum that will be highly impacted and caused to be removed. The two fruit trees have poor suitability and the remaining nine originate on the adjacent sites.  Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 6 25 Quantity 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Expected Impact Level Impact level defines how a tree may be affected by construction activity and proximity to the tree, and is described as low, moderate, or high. 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. All four trees originating on the site will be highly impacted and caused to be removed which are Japanese maple #136, Sweetgum #137, pear #138 and apple #139. The trees on the adjacent sites are not expected to be highly impacted by the project depending on the grading and drainage plans.  Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 7 25 Quantity 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Mitigation for Removals The table below indicates the recommended replacement values (Table 3). Alternatively it may be possible to create an approved landscape plan or provide an in-lieu payment. 1To measure an asymmetrical canopy of a tree, the widest measurement shall be used to determine canopy size. 2Often, it is not possible to replace a single large, older tree with an equivalent tree(s). In this case, the tree may be replaced with a combination of both the Tree Canopy Replacement Standard and in-lieu payment 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 family 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. Any in-lieu fees for single family residential shall be based on 24” box tree rates as adopted by Town Council. 4Replacement Trees shall be approved by the Town Arborist and shall be of a species suited to the available planting location, proximity to structures, overhead clearances, soil type, compatibility with surrounding canopy and other relevant factors. Replacement with native species shall be strongly encouraged. Replacement requirements in the Hillsides shall comply with the Hillside Development Standards and Guidelines Appendix A and Section 29.10.0987 Special Provisions—Hillsides.  Table 3: Town of Los Gatos Tree Canopy - Replacement Standard Canopy Size of Removed Tree (1) Replacement Requirement (2)(4) Single Family Residential Replacement Option (3)(4) 10 feet or less Two 24 inch box trees Two 15 gallon trees More than 10 feet to 25 feet Three 24 inch box trees Three 15 gallon trees More than 25 feet to 40 feet Four 24 inch box trees or two 36 inch box trees Four 15 gallon trees More than 40 feet to 55 feet Six 24 inch box trees; or three 36 inch box trees Not available Greater than 55 feet Ten 24 inch box trees; or ﬁve 36 inch box trees Not available Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 8 25 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Tree Protection Tree protection focuses on avoiding damage to the roots, trunk, or scaffold branches (Appendix D). The most current accepted method for determining the TPZ is to use a formula based on species tolerance, tree age/vigor, and trunk diameter (Matheny, N. and Clark, J. 1998) (Fite, K, and Smiley, E. T., 2016). Preventing mechanical damage to the trunk from equipment or hand tools can be accomplished by wrapping the main stem with straw wattle or using vertical timbers. Tree protection for this project would consist of a fence at the property setbacks or close to them on the north and west side of the property. Conclusion The plans indicate the existing structure will be demolished and a new residence constructed. The inventory contains 13 trees comprised of 8 different species with no Large Protected, seven Protected, and three Exempt while the remaining trees are less than twelve inches in diameter they originate on the adjacent sites. Most of the trees are in fair condition with four good, eight fair, and one in poor shape. Two trees have fair suitability for preservation which are the Japanese maple and sweetgum that will be highly impacted and caused to be removed.

The trees on the adjacent sites are not expected to be highly impacted by the project depending on the grading and drainage plans. Replacement trees will be required and any combination of trees listed with crown diameters between 25 and 40 feet will be required for the Japanese maple and Sweetgum removals. Tree protection for this project would consist of a fence at the property setbacks or close to them on the north and west side of the property. A total of 13 trees were appraised for a rounded depreciated value of $26,350.00 using the Trunk Formula Method.  Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com of 9 25 15921 Linda Avenue, Los Gatos Tree Inventory and Assessment May 29, 2019 Recommendations Pre-construction and Planning Phase 1.Place tree numbers and tree protection fence locations and guidelines on the plans including the grading, drainage, and utility plans. Create a separate plan sheet that includes all protection measures labeled “T-1 Tree Protection Plan.” 2.Place tree protection fence the property setbacks or close to them on the north and west side of the property. 3.Provide a landscape plan that accounts for the loss in tree canopy to include in tabular form the required replacements in accordance with the Town’s Tree Canopy Replacement Standard. 4.All tree maintenance and care shall be performed by a qualified arborist with a C-61/D-49 California Contractors License. Tree maintenance and care shall be specified in writing according to American National Standard for Tree Care Operations: Tree, Shrub and Other Woody Plant Management: Standard Practices parts 1 through 10 and adhere to ANSI Z133.1 safety standards and local regulations. All maintenance is to be performed according to ISA Best Management Practices. 5.Refer to Appendix D for general tree protection guidelines including recommendations for arborist assistance while working under trees, trenching, or excavation within a trees drip line or designated TPZ/CRZ. 6.Provide a copy of this report to all contractors and project managers, including the architect, civil engineer, and landscape designer or architect. It is the responsibility of the owner to ensure all parties are familiar with this document. 7.Arrange a pre-construction meeting with the project arborist or landscape architect to verify tree protection is in place, with the correct materials, and at the proper distances.

Cost Approach: An indication of value by adding the land value to the depreciated value of improvements. Defect: An imperfection, weakness, or lack of something necessary. 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 defined by the branch spread or a single plant or group of plants. The outer extent of the tree crown. Form: describes a plant’s habit, shape or silhouette defined by its genetics, environment, or management. Health: Assessment is based on the overall appearance of the tree, its leaf and twig growth, and the presence and severity of insects or disease. 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.

Tree Protection Zone (TPZ): Defined 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. Trunk Formula Method: Method to appraise the monetary value of trees considered too large to be replaced with nursery or field grown stock. Based on developing a representative unit cost for replacement with the same or comparable species of the same size and in the same place, subject to depreciation for various factors. Contrast with replacement cost method. 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.

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.
