I can typically perform the required services with some advanced notice. Site visits and on-site assessments can be performed with 72 hours notice and written reports can be expected within 14 days after the initial assessment. Time constraints would consist of required expert witness testimony or planned vacations. Time is always of the essence and projects can be expedited within reason if necessary. Project Approach Below is the typical project approach for pre-development assessments including three phases which are as follows: planning, protection, and construction. Listed below is the typical assignment for such a project: Phase 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/circumference), condition (health and structure), and suitability for preservation. The report will contain findings and recommendations, tables with tree information, photographs, and locations placed on a map if required. Trees will have aluminum number tags affixed to them for on site identification and report reference. Provide construction influence ratings for the trees that will be affected by the project. Phase 2: Provide a tree protection plan for trees to be retained. Establish tree protection zone distances and critical root zone distances along with requirements for preservation during pre- construction, construction, and post construction care. Tree protection fencing and distances can be placed on a map provided if necessary. Phase 3: Monitor construction activity to provide observations and recommendations for care as on-site conditions change and unexpected impacts that may occur. Provide construction monitoring field forms and photos as required. Project issues: Changes in design that create greater conflict than first anticipated. Grading, drainage, utility, and landscape changes. Unanticipated basement over-excavations. Water to site cut off. Tree protection fence removed. Resolutions: Contact the project manager and authority of jurisdiction regarding the changes or violations of conditions of approval. Provide appropriate mitigation measures to rectify the issues in a timely manner.

Three coast redwoods are indicated as to be retained and preserved. The inventory contains 18 trees comprised of 9 different species. One coast redwood (Sequoia sempervirens) is considered Large Protected and nine trees fruit are Exempt. Four trees are in good condition, nine fair, and five poor. There are some large trees on the site that are in fair or poor shape including Douglas-firs (Pseudotsuga menziesii) #286, #287, #293, and #294. These large specimens have some defects that could pose safety issues under new site occupancy. Three coast redwoods are indicated to be retained and preserved #290, #291, and #292 but only #290 could realistically be preserved based on the plans. The issues impacting the two trees to be preserved are the basement and required over-excavation along with the detention basin adjacent to the trees. Tree protection fence and irrigation will need to be placed around coast redwood #290. The plans indicate a Type III (trunk protection only) protection scheme around trees #291 and #292, but the grading and excavation around these trees may be detrimental without more detail. 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, structure, and form), and suitability for preservation ratings. Affix number tags on the trees for reference on site and on plans. •Provide tree protection specifications, guidelines, and impact ratings for those affected by the project. •Provide appraised values using the Trunk Formula Technique. Limits of the assignment •The information in this report is limited to the condition of the trees during my inspection on January 8, 2021. No tree risk assessments were performed. •Tree heights and canopy diameters are estimates.

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 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). The plans are to tear down the existing structure and build a new residence with a garage in the back of the site. Three coast redwoods are indicated as to be retained and preserved. There is an arborist’s report pasted to the T-1 sheet but it does not meet the required criteria to be accepted by the Town for the purposes of the project.

A fruit or nut tree that is less than eighteen (18) inches in diameter (ﬁfty-seven-inch circumference).2 Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 3 29 Quantity 32 Walnut Avenue, Los Gatos Tree Inventory, Assessment and Protection Report January 26, 2021 Analysis Tree appraisal was performed according to the Council of Tree & Landscape Appraisers Guide for Plant Appraisal 10th Edition, 2019 (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 Technique” (Appendix B). “Trunk Formula Technique” is calculated as follows: Basic Tree Cost = (Unit tree cost x Appraised trunk area), Appraised Value = (Basic tree cost X functional Limitations (percentage) X Condition (percentage) X External Limitations (percentage)). The trunk formula valuations are based on four tree factors; size (trunk cross sectional area), condition, functional limitations, and external limitations. There are two steps to determine the overall value. The first step is to determine the “Basic Tree Cost” based on size and unit tree cost. Unit tree cost is calculated by dividing the nursery wholesale cost of a 24 inch box specimen and its replacement size (cost per square inch trunk caliper) which is determined by the Species Classification and Group Assignment, 2004 Western Chapter Regional Supplement. The cost of the 24 inch box wholesale specimen was determined through personal communications with BrightView and Normans nurseries in Farmington and Central Wholesale in San Jose for an average of $214.00. The second part is to depreciate the tree’s Basic Cost through an assessment of condition, functional limitations, and external limitations. The condition assessment guidelines and percentages are defined in the “Condition Rating” section of this report. Functional limitations are based on factors associated with the tree’s interaction to its planting site that would affect condition, limit development, or reduce the utility in the future and include genetics, placement, and site conditions for the individual tree. External limitations are outside the property, out of control of the owner and also affect condition, limit development, or reduce the utility in the future (i.e power lines, municipal restrictions, drought adaptations, or species susceptibility to pests). There were 18 trees appraised for a rounded depreciated value of $57,770.00. Appraisal worksheets are available upon request Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 4 29 32 Walnut Avenue, Los Gatos Tree Inventory, Assessment and Protection Report January 26, 2021 Discussion Condition Rating A tree’s condition is a determination of its overall health, structure, and form. The assessment considered all three criteria 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. Four trees are in good condition, nine fair, and five poor (Chart 1). There are some large trees on the site that are in fair or poor shape including Douglas-firs #286, #287, #293, and #294. These large specimens have some defects that could pose safety issues under new site occupancy. Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 5 29 Quantity 32 Walnut Avenue, Los Gatos Tree Inventory, Assessment and Protection Report January 26, 2021 Suitability for Conservation A tree’s suitability for preservation is determined based on Functional and External Limitations (ISA, 2019). 3 •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. Three trees have good suitability for preservation while fifteen are poorly suited for retention. Trees with good suitability include coast redwoods #290, #291, and #292 along the north side. The most significant tree on the lot is the centrally located Douglas-fir #286 with fair suitability due to size, location, and longevity in an urban setting. The other Douglas-fir are not suitable for retention but one of those trees may originate on the adjacent site (#294). 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. Three coast redwoods are indicated to be retained and preserved #290, #291, and #292 but only #290 could realistically be preserved based on the plans. The issues impacting the two trees to be preserved are the basement excavation and required over-excavation along with the detention basin adjacent to the trees. Functional Limitations are based on factors associated with the tree’s interaction to its planting site affecting plant condition, limiting plant 3 development, or reducing the utility in the future and include genetics, placement, and site conditions for the individual tree (ISA, 2019). External Limitations are outside the property, out of control of the owner and also affect plant condition, limit plant development, or reduce the utility in the future (i.e power lines, municipal restrictions, drought adaptations, or species susceptibility to pests) (ISA, 2019).

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 (Appendix D). Tree protection fence and irrigation will need to be placed around coast redwood #290 at a radius of 6 to 8 times the trunk diameter. The plans indicate a Type III (trunk protection only) protection scheme around trees #291 and #292 but the grading and excavation around these trees may be detrimental. This type of protection and retention of these trees will need to be further explored. Conclusion The plans are to tear down the existing structure and build a new residence with a garage in the back. Three coast redwoods are indicated as to be retained and preserved. There is an arborist’s report pasted to the T-1 sheet but it does not meet the required criteria to be accepted by the Town for the purposes of the project. The inventory contains 18 trees comprised of 9 different species. One coast redwood is considered Large Protected and nine trees are Exempt. Four trees are in good condition, nine fair, and five poor. There are some large trees on the site that are in fair or poor shape including Douglas-firs #286, #287, #293, and #294. These large specimens have some defects that could pose safety issues under new site occupancy. Three coast redwoods are indicated to be retained and preserved #290, #291, and #292 but only #290 could realistically be preserved based on the plans. The issues impacting the two trees to be preserved are the basement and required over-excavation along with the detention basin adjacent to the trees. Tree protection fence and irrigation will need to be placed around coast redwood #290 at a radius of 6 to 8 times the trunk diameter distance.

Update the T-1 plan sheet to reflect the tree numbers provided in Appendix A and B of this report. The report by Urban Tree Management should be removed from this plan sheet as it does not contain any protection specifications or Town requirements. 2.Provide the extent of excavation for the basement, light well, and the stormwater detention pond to obtain a better understanding or feasibility of retaining coast redwoods #291 and #292. 3.Verify ownership of #294 which appears off property. 4.Place tree protection fence around coast redwood #290 at a radius of 25 to 33 feet (6x to 8x the trunk diameter). Install temporary irrigation or soaker hoses in the tree protection zone and provide supplemental watering during construction. Monitor watering times or amounts to ensure adequate soil saturation. (A 5/8” soaker hose requires about 200 minutes to deliver one inch of water to a garden. This number is affected by the length of the hose and the overall rate of flow from the faucet. A good rule of thumb is to expect about ½ GPM as a standard faucet flow rate.). Infrequent deeper watering is preferred and could be as much as 500 gallons per soaking. 5.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.

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. They are encased in jute, nylon, or other photo degradable materials, and have an average weight of 35 pounds.

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 Technique: 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.

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 in writing according to the most recent ANSI A-300A Standards and Limitations and performed according to ISA Best Management Practices while adhering to ANSI Z133.1 safety standards. Trees that need to be removed or pruned should be identified in the pre-construction walk through.

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 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). Plans The plans indicate a new Accessory Dwelling Unit in the back of the property on the hillside with a new driveway extension leading to the structure extending off the top of the existing driveway.

Six (6) coast live oaks are considered Large Protected (however five are “Large Protected” by aggregate of stems with only one have a single stem larger than 24 inches in 1 diameter) and no trees are Exempt . 2 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). A fruit or nut tree that is less than eighteen (18) inches in diameter (ﬁfty-seven-inch circumference).2 Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 3 28 Quantity 104 Angel Court, Los Gatos Tree Inventory, Assessment and Protection Report August 18, 2021 Analysis Tree appraisal was performed according to the Council of Tree & Landscape Appraisers Guide for Plant Appraisal 10th Edition, 2019 (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 Technique” (Appendix B). “Trunk Formula Technique” is calculated as follows: Basic Tree Cost = (Unit tree cost x Appraised trunk area), Appraised Value = (Basic tree cost X functional Limitations (percentage) X Condition (percentage) X External Limitations (percentage)). The trunk formula valuations are based on four tree factors; size (trunk cross sectional area), condition, functional limitations, and external limitations. There are two steps to determine the overall value. The first step is to determine the “Basic Tree Cost” based on size and unit tree cost. Unit tree cost is calculated by dividing the nursery wholesale cost of a 24 inch box specimen and its replacement size (cost per square inch trunk caliper) which is determined by the Species Classification and Group Assignment, 2004 Western Chapter Regional Supplement. The cost of the 24 inch box wholesale specimen was determined through personal communications with BrightView and Normans nurseries in Farmington and Central Wholesale in San Jose for an average of $214.00. The second part is to depreciate the tree’s Basic Cost through an assessment of condition, functional limitations, and external limitations. The condition assessment guidelines and percentages are defined in the “Condition Rating” section of this report. Functional limitations are based on factors associated with the tree’s interaction to its planting site that would affect condition, limit development, or reduce the utility in the future and include genetics, placement, and site conditions for the individual tree. External limitations are outside the property, out of control of the owner and also affect condition, limit development, or reduce the utility in the future (i.e power lines, municipal restrictions, drought adaptations, or species susceptibility to pests). There were twenty-four (24) trees appraised for a rounded depreciated value of $77,710.00. Appraisal worksheets are available upon request Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 4 28 104 Angel Court, Los Gatos Tree Inventory, Assessment and Protection Report August 18, 2021 Discussion Condition Rating A tree’s condition is a determination of its overall health, structure, and form. The assessment considered all three criteria 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 good condition and consist of coast live oaks in their natural habitat. Seventeen trees are in good condition, six fair, and one in poor shape.

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. Eight trees will caused to be removed. The plans indicate three within the footprint of the proposed driveway and ADU, however there are five more directly adjacent to the proposed structures. Seven trees are indicated as moderate to highly impacted depending on construction and grading activity. There are some trees near the proposed new driveway extension but the plans only indicate the extent of the driveway. In my experience there will need to be grading on either side of the proposed driveway to make the cut into the hillside where it is located. The limits of grading are not clear for either the driveway or the building pad. The utility connection locations should be modified to avoid bisecting the root zones as they are currently indicated on the plans.

The applicant will be required to replace 8 protected trees according to the ordinance. 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.

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 (Appendix D). Tree protection will consist of fence around the trees to be retained. The radii will be six times the trunk diameter distance based on young tolerant specimens. Trees will need to enclosed in groups. Conclusion The plans indicate a new Accessory Dwelling Unit in the back of the property on the hillside with a new driveway extension leading to the structure extending off the top of the existing driveway. The inventory contains twenty-four (24) trees comprised of three (3) different species. Six (6) coast live oaks are considered Large Protected (however five are “Large Protected” by aggregate of stems with only one have a single stem larger than 24 inches in diameter) and no trees are Exempt. Most of the trees are in good condition and consist of coast live oaks in their natural habitat. Seventeen trees are in good condition, six fair, and one in poor shape. Eight trees will caused to be removed. The plans indicate three within the footprint of the proposed driveway and ADU, however there are five more directly adjacent to the proposed structures. Seven trees are indicated as moderate to highly impacted depending on construction and grading activity. There are some trees near the proposed new driveway extension but the plans only indicate the extent of the driveway. In my experience there will need to be grading on either side of the proposed driveway to make the cut into the hillside where it is located. The limits of grading are not clear for either the driveway or the building pad. The utility connection locations should be modified to avoid bisecting the root zones as they are currently indicated on the plans. The applicant will be required to replace 8 protected trees according to the ordinance. Alternatively it may be possible to create an approved landscape plan or provide an in-lieu payment. Tree protection will consist of fence around the trees to be retained. The radii will be six times the trunk diameter distance based on young tolerant specimens. Trees will need to enclosed in groups. There were twenty-four (24) trees appraised for a rounded depreciated value of $77,710.00.

Make sure the trees are clearly indicated for removal on all the plans. The trees should also be very clearly marked on site prior to removal. 2.Provide some detail as to how the driveway cut will be constructed and where the spoils will go if any. If there is any required over-excavation to create the driveway those limits need to be on the plans. 3.Re-route the utilities to avoid bisecting the root zones of the trees. Show all utility locations and connections on the plans including sanitary sewer, water, and any required electric. 4.Place tree protection around the groups of trees to be preserved adjacent to the driveway and near the trellis. There is already a fence #582-#585. 5.Install temporary irrigation or soaker hoses in all tree protection zones and provide supplemental watering during construction within all TPZ areas. Monitor watering times or amounts to ensure adequate soil saturation. (A 5/8” soaker hose requires about 200 minutes to deliver one inch of water to a garden. This number is affected by the length of the hose and the overall rate of flow from the faucet. A good rule of thumb is to expect about ½ GPM as a standard faucet flow rate.). Infrequent deeper watering is preferred. 6.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. 7.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. 8.Place all the tree protection fence locations and guidelines on the plans including the grading, drainage, and utility plans. Alternatively create a separate plan sheet that includes all three protection measures labeled “T-1 Tree Protection Plan.” Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 9 28 104 Angel Court, Los Gatos Tree Inventory, Assessment and Protection Report August 18, 2021 9.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. 10.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. They are encased in jute, nylon, or other photo degradable materials, and have an average weight of 35 pounds.

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 Technique: 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 any roots are cut or torn during construction, it is critical that you sharply cut all the ends of any exposed roots immediately. Failure to do so will leave crushed and torn roots. This leads to decay and inhibits growth of new roots. 2. Pile soil on the side of the trench opposite the tree. If this is not possible, place the soil on a plastic tarp, plywood or a thick bed of mulch. 3. Do not compact the backfill on the trench more than its original firmness. 4. Water the backfill to allow the roots to begin healing. Trenching near a tree can kill as much as 40%-RIWKHWUHH¶V roots.

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 first 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 first 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).  Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 22 28 104 Angel Court, Los Gatos Tree Inventory, Assessment and Protection Report August 18, 2021 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 dripline of the tree unless approved by the Director. 3.Prohibit disposal or depositing of oil, gasoline, chemicals or other harmful materials within the dripline of or in drainage channels, swales or areas that may lead to the dripline 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. 6.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 protected tree during construction so that proper treatment may be administered. Prohibited Activities The following are prohibited activities within the TPZ: •Grade changes (e.g. soil cuts, fills); •Trenches; •Root cuts; •Pedestrian and equipment traffic that could compact the soil or physically damage roots; •Parking vehicles or equipment; •Burning of brush and woody debris; •Storing soil, construction materials, petroleum products, water, or building refuse; and, •Disposing of wash water, fuel or other potentially damaging liquids.

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 in writing according to the most recent ANSI A-300A Standards and Limitations and performed according to ISA Best Management Practices while adhering to ANSI Z133.1 safety standards. Trees that need to be removed or pruned should be identified in the pre-construction walk through.
