APN 527-56-027. The project is categorically exempt pursuant to the California Environmental Quality Act (CEQA) Guidelines, Section15303(a): New Construction. The inventory contains twenty trees comprised of six (6) different species. There are five Large Protected trees and none are Exempt or Street Trees. Ten trees are in good condition, nine fair, and one is in poor shape. The two toyon and coast live oak #259 are probably in the worst shape. Four tree will be highly impacted and likely need to be removed and include #259, #260, #261, and #263. Only #263 is indicated for removal on the plans. There is a new sewer and other infrastructure adjacent to the other trees along the side of the property (plan view east). The applicant will be required to replace four protected trees. Tree protection will consist of fence around those to be retained at a specified distance of either eight times their trunk diameter in radius or along existing hard-scapes (driveway or roadway for the trees in front). There were twenty protected trees appraised for a rounded depreciated value of $99,980.00.

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 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).

There are five Large Protected trees and none are 1 Exempt or Street Trees (Chart 1). 2 3 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). Species listed in 29.10.0970 subsection (2).2 Street tree means a tree in a public place, or along or within a public street or right-of-way.3 Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 3 28 Quantity 119 Harwood Court Tree Inventory, Assessment and Protection Report September 12, 2024 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 protected trees appraised for a rounded depreciated value of $99,980.00. Appraisal worksheets are available upon request.

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. Ten trees are in good condition, nine fair, and one is in poor shape. The two toyon and coast live oak #259 are probably in the worst shape (Chart 2).

The applicant will be required to replace four protected trees. Alternatively it may be possible to create an approved landscape plan or provide an in-lieu payment. The landscape plan does not indicate any replacement trees. 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.

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. Four tree will be highly impacted and likely need to be removed and include #259, #260, #261, and #263. Only #263 is indicated for removal on the plans. There is a new sewer and other infrastructure adjacent to the other trees along the side of the property (plan view east). Tree Protection Typically there are three different tree protection schemes which are called Type I (Appendix D1), Type II and Type III (Appendix D2) trunk protection only. The tree protection zone (TPZ) is the defined area in which certain activities are prohibited to minimize potential injury to the tree. There are two tree protection zones determined which include the “calculated” and “specified”. The “calculated” tree protection zone is determined by a multiplication factor based on species tolerance, tree age/vigor/health, and trunk diameter. The “specified” tree protection zone is adjusted in size and shape to accommodate the existing infrastructure, planned construction, and specific site constraints. This “specified” zone includes tree canopy conformation, visible root orientation, size, condition, maturity, and species tolerances (Gilpin, R, Hauer, R, Matheny, N, and Smiley, E.T. 2023). Tree protection will consist of fence around those to be retained at a specified distance of either eight times their trunk diameter in radius or along existing hard-scapes (driveway or roadway for the trees in front).

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%-50% of the tree’s roots. If the tree you are working around is in a confined space and your equipment will be coming close, it is important for you to protect the trunk. Wrap the tree trunk in old tires or place 2” x 4” studs around the tree and rope or band them together.

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).

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. Monarch Consulting Arborists LLC - P.O Box 1010, Felton, CA 95018 831.331.8982 - rick@monarcharborist.com Page of 23 28 119 Harwood Court Tree Inventory, Assessment and Protection Report September 12, 2024 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 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.
