A Tree Permit (TP) is also requested to remove seven protected California black walnut trees and one coast live oak tree and replace with 24 coast live oak trees on site. RECOMMENDATION: Adopt the attached Resolution (Attachment A) approving Development Review and Tree Permit No. PL2025-27, based on the findings of Diamond Bar City Code (DBCC) Sections 22.48 and 22.38, subject to conditions. BACKGROUND: The project site is located in the Diamond Bar Country Estates (The Country), on the north side of Ridge Line Road, east of Rocky View Road. The property is currently developed with an existing single-family residence and accessory barn structure in the rear yard. An arborist report prepared for this project (Psomas, February 26, 2026) identified 28 protected trees and 68 unprotected trees on the property. The proposed project is still under review by the Diamond Bar Country Estates Architectural Committee. The property is legally described as Lot 34 of Tract No. 30091, and the Assessor's Parcel Number (APN) is 8713-005-010. Page 10 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 Adjacent Property to the East r ........ ...... ! LA Adjacent Property to the West The following table summarizes the land use status of the subject property and its surroundings: General Plan Designation Zoning District Land Use Site Rural Residential RR Single -Family Residential North Medium Density Residential RR Open Space South Rural Residential RR Single -Family Residential East Rural Residential RR Single -Family Residential West Rural Residential RR Single -Family Residential Protect Description Site Plan As stated, the property's gross lot area is 66,647 square feet (1.53 acres), which includes a 32-foot wide private street easement along the frontage of Ridge Line Road. The property is a rectangular -shaped lot with a net buildable area (i.e., minus the private street easement) of 62,291 square feet (1.43 acres). The property is a hillside property with a descending slope at 37 percent that starts from the private street easement to the rear property line. The proposed residence will be situated 30 feet from the edge of the private street easement along Ridge Line Road. Page 12 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 The main entrance faces Ridge Line Road, and a circular driveway provides access to two three -car garages. Due to the site's topography, the entrance is located below street grade and oriented toward a below -grade courtyard with a fountain. The project includes 1,377 square feet of covered terrace and patio areas, as well as 2,072 square feet of uncovered terrace and patio areas distributed throughout the property. Rear yard improvements, including a pool and spa, are also proposed. There are 28 protected trees on the property. Eight are proposed for removal, as further discussed under the "Tree Permit" section below. Gradina Plan The applicant is proposing to cut 1,200 cubic yards and fill 1,450 cubic yards of soil throughout the property to create a buildable pad that can support the proposed residence and rear yard. Therefore, 250 cubic yards would have to be imported to the site. Standard dump truck capacities range from 10 to 15 cubic yards, so the proposed amount of import would require 17 to 25 total truck trips. The proposed grading activities are limited to areas in proximity to the residence, preserving some of the site's unimproved natural slope. The applicant is proposing up to four tiers of retaining walls, with a maximum height of four feet, at the rear of the property to accommodate the property's steep slope, support fills above the natural grade, and expand the buildable pad for the house and rear yard. All exposed portions of the proposed retaining walls will have a decorative finish, with the use of painted stucco to match the house. Architecture The architectural style is a modern Prairie design with a low-pitched standing seam metal roof, deep eaves, large floor - to -ceiling windows, and a balanced, symmetrical fagade. Building materials consist of stained wood panels, off-white and gray exterior plaster, aluminum/metal doors and windows, and powder coated wrought -iron railings. Additional architectural elements include wood panel garage door and eaves, limestone freestanding walls, metal wall paneling/cladding that complement the overall fagade. The exterior color palette utilizes cool, earth -toned hues consistent with the modern Prairie design to preserve the hillside's aesthetic. Rendering of Front (West) Elevation The proposed three -level house's floor plan comprises the following components: • Basement Floor- Entertainment room, game parlor, wine tasting room, exercise room, spa with lounge, massage room with bathroom, staff room, two bedrooms with bathrooms, a powder room, pool bathroom, laundry room and two mechanical rooms; Page 13 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 First Floor - Great room, kitchen with wok kitchen, dining room, office, prayer room, master suite with a bathroom and walk-in closet, and two bedrooms with bathrooms; Second (Street Level) Floor - Outdoor living room, parlor, two bedrooms with bathrooms, powder room, and two three -car garages. Covered/uncovered terrace areas totaling 3,449 square feet and an elevator are proposed throughout the three levels of the residence. The floor area distribution is summarized below: PROJECT SUMMARY (square footage) Living Area 14,304 o Basement Floor 5,894 o First Floor 5,915 o Second Floor 2,495 Non -Livable Area 5,355 o Garage 1,518 o Covered terrace, patios 1,377 o Uncovered terrace, patios 2,072 o Mechanical/electrical rooms 388 TOTAL FLOOR AREA 19,659 The height of the building is 34'-10", measured from the finished grade to the highest point of the roofline. Landscape Plan A total of 20 unprotected trees and seven protected California black walnut trees and one protected coast live oak tree are proposed for removal. The protected trees will be replaced at a 3:1 ratio and a condition of approval is included in the attached Resolution requiring the planting of 24 coast live oak trees. The Tree Permit section below provides further analysis on the removal of trees and appropriate mitigation. All other trees will be replaced at a 1:1 ratio. The applicant is proposing a variety of trees to be planted throughout the property, including six New Zealand Christmas trees (two 72-inch box, two 60-inch box, and two 48-inch box), eighteen 48-inch box magnolia trees, ten 36- inch box Saratoga laurel trees, and twenty-four 24-inch box coast live oak trees in the front, side and rear yards. A total of 58 trees will be planted to replace the 28 trees proposed for removal. At project completion, there will be a total of 126 trees onsite (58 replacement trees and 68 existing trees to be preserved). Additionally, various 5-gallon and 1-gallon shrubs that have a variety of color, texture, and form are proposed throughout the front, side and rear yards. Overall, landscaping consists of drought tolerant and non-invasive species to minimize irrigation and reduce the area of turf. The project is required to comply with the City's Water Efficient Landscaping Ordinance, and compliance will be verified during building plan check and final inspections. The subject property is located within the Los Angeles County Fire Department "Very High and High Fire Hazard Severity Zone." Therefore, the proposed landscaping must comply with the Fire Department's Fuel Modification Plan requirements. The landscape plans will be submitted for review and approval by the Fire Department during building plan check. ANALYSIS: Review Authority The proposed project requires Planning Commission review and approval of two entitlement applications: Page 14 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 Development Review (DR) and a Tree Permit (TP). The analysis that follows provides the basis for staff's recommendation to approve the DR and TP applications. Development Review (DBCC Chapter 22.48) New construction of a single-family home requires Planning Commission approval of a Development Review application. Development Review approval is required to ensure compliance with the City's General Plan policies, development standards, and design guidelines, and to minimize adverse effects of the proposed project upon the surrounding properties and the City in general. As stated in Section 22.48.010 of the Development Code, the Development Review process was established to ensure that new development and additions to existing development are consistent with the General Plan "through the promotion of high functional and aesthetic standards to complement and add to the economic, physical, and social character" of Diamond Bar. Development Standards: The following table compares the proposed project with the City's development standards for residential development in the RR zone: hL_ Residential - - ■ s - ndardls • ■ • - • Meets Requirements 30 feet 30 feet Yes IS feet on one side, 15 feet - Southwest side Yes 0 feet an the other 10 feet - Northeast side 30'-9" -Southwest side Yes _ 1 14'-Z' - Northeast side 25 feet 25 feet Yes ".-i"aximum of 30 12.57D Yes 35 {eet 34'-10" Yes 2-car garage 6-car garage Yes 4-foot exposed 4-foot exposed Yes (supporting fill) (supporting fill) Tree Permit (DBCC Section 22.38.110) A Tree Permit is required when the removal or protection of a protected tree is requested. A protected tree is any of the following: • Native oak, walnut, sycamore and willow trees with a diameter at breast height ("DBH" i.e., 4.5 feet above ground level) of eight inches or greater, and located on parcels larger than one-half acre in area; • Trees of significant historical or value as designated by the City Council; • Any tree required to be preserved or relocated as a condition of approval for a discretionary permit; • Any tree required to be planted as a condition of approval for a discretionary permit; or • A stand of trees, the nature of which makes each tree dependent upon the others for survival. Page 15 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 Trees that are so damaged, diseased or in danger of falling (as verified by an arborist) that cannot be effectively preserved, or its presence is a threat to other protected trees or existing or proposed structures are exempted from being replaced at a three to one (3:1) ratio. The applicant submitted a tree report prepared by a licensed arborist (Psomas) dated February 26, 2026. There are 17 California black walnut trees, 10 coast live oaks and one Inland scrub oak trees that are considered protected with a DBH that ranges between 8.2 and 43.4 inches. 20 protected trees will remain on the property and eight protected trees (seven California black walnuts and one coast live oak) are proposed for removal as it will impact grading activities. Protected trees will be replaced at a 3:1 ratio with 24 coast live oak trees, which is the required amount of mitigation trees to be planted. Due to the scarcity of California black walnuts in local inventories, it is recommended that coast live oak trees be used as mitigation trees. Therefore, twenty-four 24-inch box coast live oak trees will be planted on the rear slope of the property (exact location to be determined during plan check to comply with the Fire Department's Fuel Modification Plan requirements). The arborist notes that there are three additional protected trees (one California black walnut tree and two coast live oaks) that may be impacted during construction. Replacement planting will be required if an arborist determines during construction that this encroachment would be expected to cause a significant decline in tree health. 4 �.. ir. l Location of Trees and Tree Impacts Page 16 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 11111 s a,sss �;�;� 111191II1!11111y11r11 �I�I ilia fil I l iA11 ililil 11 Elam f�. €LINO .JliiliiiC7 I '1;� Ilrlrlrlll E' IL c I rll '1'1'1'1'1'r ,¢�■�■�i 11 �A 0fit 912 r 1111 11 n,yyl 1 yI r 1 �Ir111rlrlrl I■■■■■■I 1' i4 'i'i'i'i'i■i'i'■ �. `�.. r'1 II�I�Irl�l�l !J 141����1 �1 �Il ■■ � _ _ _ _ ./ 111 1 1 1 1■ .r; �� III$ I r■r4 i'i'i'ili' � iiiin ii M ' 1€ t � iao�a a ITU1 Ill�i'i �1 I I PIN r7r ri�i� i I.!j��j!ijijij:llp!1i III!

For work close to the protected zone, protective measures shall include, but are not limited to the following: • Tree protection fencing will be a minimum of five feet high and located five feet from the drip line of the trees. • Fencing will be of a flexible configuration or chain link, supported by vertical posts at a maximum of ten -foot intervals to keep the fencing upright and in place. • A sign posted on the fencing which states "Warning: Tree Protection Zone" and stating the requirements of all workers in the protection zone. • Throughout the course of construction, the tree protection fencing shall be maintained and the site shall be maintained and cleaned at all times. No construction staging or disposal of construction materials or byproducts, including but not limited to paint, plaster, or chemical solutions is allowed in the tree protection zone. • No grade changes shall be made within the protective barriers without prior approval by the City. Where roots greater than one inch in diameter are damaged or exposed, the roots shall be cleanly saw cut and covered with soil in conformance with industry standards. • Excavation or landscape preparation within the protective barriers shall be limited to the use of hand tools and small hand-held power tools and shall not be of a depth that could cause root damage. • No attachments or wires other than those of a protective or nondamaging nature shall be attached to a "protected tree." • No equipment or debris of any kind shall be placed within the protective barriers. No fuel, paint, solvent, oil, thinner, asphalt, cement, grout or any other construction chemical shall be stored or allowed in any manner to enter within the protected barrier. • If access within the protection zone of a protected tree is required during the construction process, the route shall be covered in a six-inch mulch bed in the drip line area and the area shall be aerated and fertilized at the conclusion of the construction. • When the existing grade around a protected tree is to be raised, drain tiles shall be laid over the soil to drain liquids away from the trunk. The number of drains shall depend upon the soil material. Lighter sandy soils and porous gravelly material required fewer drains than heavy nonporous soils like clay. Dry wells shall be large enough to allow for maximum growth of the tree trunk. Dry well walls shall be constructed of materials that permit passage of air and water. • When the existing grade around a tree is to be lowered, either by terracing or a retaining wall, a combination may be used to lower grade. With either method, the area within the drip line shall be left at the original grade. Page 17 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 The retaining wall shall be porous to allow for aeration. • A certified arborist shall be required to monitor construction activities within, or nearby, "protected trees" drip line protection zone. • Pruning of any branches greater than three inches in diameter or removal of more than ten percent of the total canopy shall be overseen by a certified arborist. • Trees that have been destroyed or that have received major damage during construction shall be replaced prior to final inspection. • Any trees that are to be retained on site but are damaged by construction activities (e.g., soil disturbance within the drip line or excessive pruning) should be monitored for a period of at least two years to detect any health impacts that may require additional tree replacement. These protective measures are included as conditions in the attached resolution. Compliance with Hillside Management Ordinance (DBCC Section 22.22) The proposed project was reviewed for compliance with the City's Hillside Management Design Guidelines and regulations. The project complies with all of the regulations and guidelines to ensure that development will complement the character and topography of hillside areas set forth in the Development Code, and incorporates the following features: • The maximum building height is 34'-10" feet, where 35 feet is allowed; • Architectural treatment is provided on all sides of the building with varying setbacks and projections; • The project is terraced on three pad levels. From the street view, the building has an appearance of a one- story structure, but the rear of the building steps down to three levels; • All proposed retaining walls associated with the building pads are at a maximum exposed height of four feet; and • Earth tone building materials and color schemes are used that blend in with the natural landscape. The project complies with all of the regulations and guidelines to ensure that development will complement the character and topography of hillside areas set forth in the Development Code. Compatibility with Neiahborhood The new house will not be intrusive to neighboring homes since the proposed house will not block existing views from adjacent properties. The properties to the east and west will continue to have views of the vista from their rear yards to the west. All properties across the street will continue to have views of the vista from their rear yards to the southeast. The proposed house will be constructed on a relatively similar building pad elevation comparable to the adjacent neighboring properties located at 23107 Ridge Line Road and 22983 Ridge Line Road, based on the topographic data from the City's GIS system. As a result, the proposed structure will not exceed the height of neighboring homes, thereby preserving existing view corridors and maintaining the visual scale and grade levels of the adjacent homes along Ridge Line Road. Furthermore, the house is terraced on three pad levels. From the street view, the building has an appearance of a one-story structure, but the rear of the building steps down to three levels. Page 18 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 Aerial View of Project Site and Adjacent Properties (Looking North) Aerial View of Project Site and Adjacent Properties (Looking South) The proposed house is comparable in mass and scale to existing homes on similar lots in The Country. The architecture in The Country is eclectic, and includes a variety of architectural designs. The scale and proportions of the proposed home are well balanced and appropriate for the site. In sum, the proposed project has been carefully designed to respect existing view corridors, maintain neighborhood scale and character, and minimize any adverse effects on adjacent residences. The project also incorporates the principles of the City's Residential Design Guidelines as follows: • The new single-family residence will conform to all development standards, including building height, lot Page 19 of 127 Agenda Item #: 6.1 Meeting Date: April 28, 2026 coverage and setbacks, which is consistent with other homes in The Country; • A gradual transition between the project and adjacent uses is achieved through appropriate setbacks, building height, landscaping, and window and door placement; • The proposed new single-family residence is appropriate in mass and scale to the site; • Elevations are treated with detailed architectural elements; • The exterior finish materials and colors blend with the natural environment; • Effective landscape design should serve the dual purpose of intrinsically enhancing a project setting, as well as integrating the landscaping into the overall architectural design. Staff finds the proposed plant palette to be diverse, and the plant selections are compatible with Southern California native landscapes; and • The proposed new single-family residence will not obstruct slot views of the vista for nearby properties.

B. RESOLUTION NOW, THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: The Planning Commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct; and 2. The Planning Commission hereby determines the Project to be Categorically Exempt from the provisions of the California Environmental Quality Act (CEQA) pursuant to the provisions of Article 19 Section 15303(a) (construction of a new single-family residence) of the CEQA Guidelines. Therefore, no further environmental review is required. C. FINDINGS OF FACT Based on the findings and conclusions set forth herein and as prescribed under Diamond Bar City Code (DBCC) Sections 22.48 and 22.38, this Planning Commission hereby finds as follows: Development Review Findings (DBCC Section 22.48.040) The design and layout of the proposed development is consistent with the applicable elements of the City's General Plan, City Design Guidelines, and development standards of the applicable district, design guidelines, and architectural criteria for special areas (e.g., theme areas, specific plans, community plans, boulevards or planned developments): The design of the Project is consistent with the applicable elements of the City's General Plan, City Design Guidelines and development standards. The City's General Plan Policy LU-P-56 requires that development on privately -owned, residentially designated land in hillside areas shall be compatible with the surrounding natural areas promoting design principles such as minimizing grading, preserving existing vistas, incorporate site and architectural design that is sensitive to the hillsides, and require fuel modification. To minimize grading, the new residence is proposed on an existing buildable pad which will be expanded to comply with the minimum rear yard setback. All exposed portions of retaining walls will have a decorative finish, with the use of split -faced block or painted stucco to match the house as to not detract from the hillside. The Project will also be required to implement fuel modification. A gradual transition between the project and adjacent uses is achieved through appropriate setbacks, building height, and window and door placement. Additionally, the design includes covered and uncovered terrace/patio areas 2 Page 22 of 127 throughout the three levels of the home. All elevations are architecturally treated and strongly articulated through projections along the visible fagade [City's Design Guidelines B. Architecture (3)]. The Project complies with all development standards of the Rural Residential zoning district by complying with all development standards such as required setbacks, building height, and lot coverage. The project site is not part of any theme area, specific plan, community plan, boulevard or planned development. 2. The design and layout of the proposed development will not interfere with the use and enjoyment of neighboring existing or future developments, and will not create traffic or pedestrian hazards; The proposed single-family house will not interfere with the use and enjoyment of neighboring existing or future developments because the use of the project site is designed for a single-family home and the surrounding uses are also single-family homes. The new house will not be intrusive to neighboring homes since the proposed house will not block existing views from adjacent properties. The properties to the east and west will continue to have views of the vista from their rear yards to the west. All properties across the street will continue to have views of the vista from their rear yards to the southeast. The proposed single-family house will not interfere with vehicular or pedestrian movements, such as access or other functional requirements of a single-family home because it complies with the requirements for driveway widths and exceeds the minimum number of required off-street parking spaces. 3. The architectural design of the proposed development is compatible with the character of the surrounding neighborhood and will maintain and enhance the harmonious, orderly and attractive development contemplated by Chapter 22.48: Development Review Standards, the City's Design Guidelines, the City's General Plan, or any applicable specific plan; The City's General Plan Policy LU-P-56 requires that residential development be compatible with the prevailing character of the surrounding neighborhood in terms of building scale, density, massing, and design. The City's General Plan Goal CC-G-4 also requires the preservation of the scale and character of existing residential neighborhoods and ensure sensitive transitions between densities and uses. The City's Design Guidelines Architecture (1) requires compatibility with the surrounding character including harmonious building style, form, size, color, material and roofline. The scale and proportions of the proposed residence are well balanced and appropriate for the 1.53 gross -acre site. The modern Prairie architectural style is compatible with other homes in the neighborhood since the architecture in The Country is eclectic, and includes a variety of architectural designs. The Project minimizes negative impacts on surrounding uses since the house will 3 Page 23 of 127 not block existing views from adjacent properties. In sum, the Project fits the character of the neighborhood on which it is proposed. 4. The design of the proposed development will provide a desirable environment for its occupants and visiting public as well as its neighbors through good aesthetic use of materials, texture, color, and will remain aesthetically appealing; The proposed residence will be designed in the modern Prairie architectural style. The project is designed to have a variety of elements to reflect the architectural style, including the following design features: low-pitched standing seam metal roof, deep eaves, large floor -to -ceiling windows, and a balanced, symmetrical fagade. Building materials consist of stained wood panels, off-white and gray exterior plaster, aluminum/metal doors and windows, and powder coated wrought -iron railings. Additional architectural elements include wood panel garage door and eaves, limestone freestanding walls, metal wall paneling/cladding that complement the overall fagade. Through the use of cool, earth -toned shades and quality materials that have texture and color, the proposed residence will not be intrusive to neighboring homes. Also, landscaping is integrated into the site to complement the massing of the house and blend in with neighboring homes and the natural environment of the site in order to maintain a desirable environment. The scale and proportions of the proposed home are well balanced and appropriate for the site. 5. The proposed development will not be detrimental to public health, safety or welfare or materially injurious (e.g., negative effect on property values or resale(s) of property) to the properties or improvements in the vicinity; and Before the issuance of any City permits, the proposed project is required to comply with all conditions within the approved resolution, and the Building and Safety Division and Public Works Departments requirements. Through the permit and inspection process, the referenced agencies will ensure that the proposed project is not detrimental to the public health, safety or welfare or materially injurious to the properties or improvements in the vicinity. 6. The proposed project has been reviewed in compliance with the provisions of the California Environmental Quality Act (CEQA). The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) as set forth under Article 19 Section 15303(a) (construction of a new single-family residence) of the CEQA Guidelines. Tree Permit Finding (DBCC Section 22.38.110) Preservation of the tree is not feasible and would compromise the property owner's reasonable use and enjoyment of property or surrounding land and M Page 24 of 127 appropriate mitigation measures will be implemented in compliance with DBCC Section 22.38.130 (Tree replacement/relocation standards) below. The applicant submitted a tree report prepared by a licensed arborist (Psomas) dated February 26, 2026. There are 17 California black walnut trees, 10 coast live oaks and one Inland scrub oak trees that are considered protected with a DBH that ranges between 8.2 and 43.4 inches. 20 protected trees will remain on the property and eight protected trees (seven California black walnuts and one coast live oak) are proposed for removal as it will impact grading activities. Protected trees will be replaced at a 3:1 ratio with 24 coast live oak trees, which is the required amount of mitigation trees to be planted. Due to the scarcity of California black walnuts in local inventories, it is recommended that coast live oak trees be used as mitigation trees. Therefore, twenty-four 24-inch box coast live oak trees will be planted on the rear slope of the property (exact location to be determined during plan check to comply with the Fire Department's Fuel Modification Plan requirements). Trees to remain will be retained and protected in place with protective, chain - link fencing to be installed prior to construction activities. These protective measures are included as conditions below. Based upon the findings and conclusion set forth above, the Planning Commission hereby approves this Application, subject to the following conditions: Development shall substantially comply with the plans and documents presented to the Planning Commission at the public hearing. 2. Prior to building permit issuance, the required landscape plan shall be designed to meet the requirements of the Los Angeles County Fire Department's Fuel Modification Plan Guidelines in terms of plant selection, placement and maintenance. The final landscape and fuel modification plans shall be submitted to the Los Angeles Fire Department for review and approval. 3. Prior to building permit issuance, a Certification of Design, together with landscape and irrigation plans prepared by a licensed landscape architect, shall be submitted to the Planning Division for review and approval by the City's Consulting Landscape Architect. Landscape and irrigation plans shall comply with the updated Water Efficient Landscaping Ordinance. 4. Prior to the issuance of a demolition, grading or building permit, the protected trees shall be barricaded by chain link fencing with a minimum height of five feet, or by another protective barrier approved by the Community Development Director or designee. Chain link fencing shall be supported by vertical posts at a maximum of ten -foot intervals to keep the fencing upright and in place. Barriers shall be placed at least five (5) feet from the drip line of the trees. A sign posted on the fencing which states "Warning: Tree Protection Zone" and stating the requirements of all workers in the protection zone. Throughout the course of construction, the tree protection fencing shall be maintained and the 5 Page 25 of 127 site shall be maintained and cleaned at all times. No construction staging or disposal of construction materials or byproducts, including but not limited to paint, plaster, or chemical solutions is allowed in the tree protection zone. The fencing plan shall be shown on the grading plan and other applicable construction documents and the Applicant, Owner or construction manager shall contact the Planning Division to conduct a site visit prior to commencement of any work to ensure this condition is met. 5. All work conducted close to the protected zone of protected trees shall be performed within the presence of a qualified arborist. A 48-hour notice shall be provided to the arborist and the Planning Division prior to the planned start of work. 6. Throughout the course of construction, the tree protection fencing shall be maintained and the site shall be maintained and cleaned at all times. No construction staging or disposal of construction materials or byproducts, including but not limited to paint, plaster, or chemical solutions is allowed in the tree protection zone. 7. No grade changes shall be made within the protective barriers without prior approval by the City. Where roots greater than one inch in diameter are damaged or exposed, the roots shall be cleanly saw cut and covered with soil in conformance with industry standards. 8. Excavation or landscape preparation within the protective barriers shall be limited to the use of hand tools and small hand-held power tools and shall not be of a depth that could cause root damage. 9. No attachments or wires other than those of a protective or nondamaging nature shall be attached to a "protected tree." 10. No equipment or debris of any kind shall be placed within the protective barriers. No fuel, paint, solvent, oil, thinner, asphalt, cement, grout or any other construction chemical shall be stored or allowed in any manner to enter within the protected barrier. 11. If access within the protection zone of a protected tree is required during the construction process, the route shall be covered in a six-inch mulch bed in the drip line area and the area shall be aerated and fertilized at the conclusion of the construction. 12. When the existing grade around a protected tree is to be raised, drain tiles shall be laid over the soil to drain liquids away from the trunk. The number of drains shall depend upon the soil material. Lighter sandy soils and porous gravelly material required fewer drains than heavy nonporous soils like clay. Dry wells shall be large enough to allow for maximum growth of the tree trunk. Dry well walls shall be constructed of materials that permit passage of air and water. 6 Page 26 of 127 13. When the existing grade around a tree is to be lowered, either by terracing or a retaining wall, a combination may be used to lower grade. With either method, the area within the drip line shall be left at the original grade. The retaining wall shall be porous to allow for aeration. 14. Pruning of any branches greater than three inches in diameter or removal of more than ten percent of the total canopy shall be overseen by a certified arborist. 15. Trees that have been destroyed or that have received major damage during construction shall be replaced prior to final inspection. 16. Any trees that are to be retained on site but are damaged by construction activities (e.g., soil disturbance within the drip line or excessive pruning) should be monitored for a period of at least two years to detect any health impacts that may require additional tree replacement. 17. If protective measures fail to ensure the survival of any protected tree during construction activity or within three years after approval of final inspection, a minimum of three 24-inch box protected species shall be planted on the property for each protected tree that dies. 18. Replacement trees shall be planted on site and shall be subject to a minimum of three years of maintenance and monitoring to ensure their successful establishment. Any trees lost or observed to be in poor or declining health within the three-year establishment period shall be replaced at a minimum ratio of 1:1 (non -protected trees) and 3:1 (protected trees). After all trees have been established, all temporary irrigation systems (i.e., those outside of project landscaping and Fuel Modification Zones) shall be removed. 19. Standard Conditions.

All standards shall include the latest additions and amendments as of the date of advertisement for bids III. Qualifications A. Landscape planting and related work shall be performed by a firm with a minimum of five years experience specializing in this type of work. All contractors and their sub -contractors who will be performing any landscap work included in this section of the specification shall be approved by the landscape architect. IV. Requirements of Regulatory Agencies A. Certificates of inspection shall accompany the invoice for each shipment of plants as may be required by law for transportation. File certificates with the landscape architect prior to acceptance of the material. Inspection by federal or state authorities at place of growth does not preclude rejection of the plants at the site. V. Submittals A. Plant Photographs: Submit color photographs of representative specimens of all specimen tree and accent plants if required by Landscape Architect. A scale rod or other measuring device shall be included in the photograph. Label each photograph with the plantname, plant size, and name of the growing nursery. 1. Caliper measurementa3hall be taken on the trunk 150 mm (6 in.) above the natural ground line for trees up to and including 100 mm (4 in.) in caliper, and 300 mm (12 in.) above the natural ground line for trees over 100 mm (4 in.) in caliper. Height and spread dimensions spefiied refer to the main body of the plant and not from branch tip to branch tip. Plants shall be measured when branches are in their normal position. If a range of sizes is given, no plant shall be less than the minimum size, and no less than 50 percent of the plants shall be as large as the maximum size specified. Measurements specified are minimum sizes acceptable after pruning, where pruning is required. Plants that meet measurements but do not possess a standard relationship between height and spread, wording to the American Standards for Nursery Stocl� shall be rejected. D. Substitutions of plant materials will not be permitted unless authorized in writing by the landscape architect. If proof is submitted in writing that a plant specified is not obtainable, consideration will be given to the nearest available size or similar variety, with a corresponding adjustment of the contract price. E. The plant list at the end of this section, or on the drawing, is for the contractor's information only, and no guaranbe is expressed or implied that quantities therein are correct or that the list is complete. The contractor shall ensure that all plant materials shown on the drawings are included in his or her bid. F. All plants shall be labeled by plant name. Labels shallbe attached securely to all plants, bundles, and containers of plant materials when delivered. Plant labels shall be durable and legible, with information given in weathe-r resistant ink or embossed process lettering. G. Selection and Tagging 1. Plants may be subject to inspection for conformity to specification requirements and approval by the landscape architect at their place of growth and upon delivery. Such approval shall not impair the right of inspection and rejection during progress of the work. H. Balled and Burlapped (B&B) Plant Materials 1. Trees designated B&B shall be properly dug with firm, natural balls of soil retaining as many fibrous roots as possible, in sizes and shapes as specified in the American Standard for Nursery Stocballs shall be firmly wrapped with nonsynthetic, rottable burlap and secured with nails and heavy, nonsynthetic, rottable twine. The root collar shall be apparent at surface of ball. Trees with loose, broken, pocessed, or manufactured root balls will not be accepted, except with special written approval before planting. (NOTE: Some nurseries practice result in the root flare being buried several inches deep. The top of the root ball may be at ground level, but the root flare actually is too deep. Remove the excess soil on the top of the root ball. Proper planting depth requires the root flare to be at or slightly above the finished grade.) I. Container Plants VI. Planting Season 1. Plants grown in containers shall be of appropriate sizdor the container as (NOTE: Planting season varies with region, climatic conditions, type of nursery stock, specified in the most recent edition of the American Standard for Nursery and other factors. Insert the appropriate planting dates for your region.) Stock and be free of circling roots on the exterior and interior of the root ball. A. Planting shall bedone within the following dates: 2. Container plants shall have been grown in the container long enough to have established roots throughout the growing medium. Deciduous trees and shrubs to ---------------------- Evergreen trees to Exceptions: ------------------------------------ B. Variance: If special conditions exist that warrant a variance in the above planting dates, a written request shall be submitted to the landscape architect stating the special conditions and the proposed variance. Permission for the variance will be given if warranted in the opinion of the landscape rchitect. Any variance in the planting season will not affect the guarantee period. VII. Utility Verification (NOTE: This section is important because the contractor may be responsible for damages to any unmarked utility.) A. The contractor shall contact thelocal utility companies for verification of the location of all underground utility lines in the area of the work. The contractor shall be responsible for all damage resulting from neglect or failure to comply with this requirement. I' a viskno ws 1 Topsoi F.11 Imported Topsoil 1.

Make all amendments of lime/sulfur and fertilizer indicated by the soil test results at the time of mixing. G. All mixing shall take place in the contractor's yard, using commercial mixing equipment sufficient to thoroughly mix all components uniformly H. Protect the planting mix from erosion prior to installation. Part 3. Execution . Excavation of Planted Areas A. Locations for plants and/or outlines of areas to be planted are to be staked out at the site. Locate and mark all subsurface utility lines. Approval of the stakeout by the landscape architect is required before excavation begins. B. Tree, shrub, and groundcover beds are to be excavated to the depth and widths indicated on the drawings. If the planting area under any tree is initially dug too deep, the soil added to bring it up to the correct level should be thoroughly tamped. 1. The sides of the excavation of all planting areas shall be sloped at a 45 degrees. The bottom of all beds shall slope parallel to the proposed grades or toward any subsurface drain lines within the planting bed. The bottom of the planting bed directly under any tree shall be horizontal such that the tree sits plumb. 2. Maintain all required angles of repose of the adjacent materials as shown on the drawings. Do not excavate compacted subgrades ofadjacent pavement or structures. 3. Subgrade soils shall be separated from the topsoil, removed from the area, and not used as backfill in any planted or lawn area. Excavations shall not be left uncovered or unprotected overnight. C. For trees and shrubs planted in individual holes in areas of good soil that is to remain in place and/or to receive amendment in the top 150mm (6 in.) layer, excavate the hole to the depth of the root ball and to widths shown on the drawing. Slope the sides of the excavation at a45 degree angle up and away from the bottom of the excavation. 1. In areas of slowly draining soils, the root ball may be set up to 75 mm (3 in.) or 1 /8 of the depth of the root ball above the adjacent soil level. 2. Save the existing soil to be used as backfill around the tree. 3. On steep slopes, the depth of the excavation shall be measured at the center of the hole and the excavation dug as shown on the drawings. D. Detrimental soil conditions: The landscape architect is to be notified, in writing, of soil conditions encountered, including poor drainage, that the contractor considers detrimental to the growth of plant material. When detrimental conditions are uncovered, planting shall be discontinued until instructions to resolve the conditions are received from the landscape architect. E. Obstructions: If rock, underground construction work, utilities, tree roots, or other obstructions are encountered in the excavation of planting areas, alternate locations for any planting shall be determined by the landscape arhitect. II. Installation of Topsoil and Planting Mix (NOTE: This section is for soil installation where soil is being replaced in large continuous beds. Where plants are to be installed in individual holes in areas where the soil does not require replacement or deep soil modification, refer to the section on planting operations for replacing the soil around the tree.) A. Prior to the installation or modification of topsoil and planting mix, install subsurface drains, irrigation main lines, lateral lines, andirrigation risers shown on the drawings. B. The landscape architect shall review the preparation of subgrades prior to the installation or modification of topsoil or planting mix. C. Do not proceed with the installation of topsoil and planting mix until all Uity work in the area has been installed. D. Protect adjacent walls, walks, and utilities from damage or staining by the soil. Use 12-mm (1 /2 in.) plywood and/or plastic sheeting as directed to cover existing concrete, metal, masonry work, and other items as directed during the progress of the work. 1. Clean up any soil or dirt spilled on any paved surface at the end of each working day. 2. Any damage to the paving or architectural work caused by the soils installation contractor shall be repaired by the generb contractor at the soils installation contractor's expense. E. Till the subsoil into the bottom layer of topsoil or planting mix. 1. Loosen the soil of the subgrade to a depth of 50 to 75 mm (2 to 3 in.) with a rototiller or other suitable device. 2. Spread a layer of the specified topsoil or planting mix 50 mm (2 in.) deep over the subgrade. Thoroughly till the planting mix and the subgrade together. 3. Immediately install the remaining topsoil or planting mix in accordance with the following specifications. Protct the tilled area from traffic. DO NOT allow the tilled subgrade to become compacted. 4. In the event that the tilled area becomes compacted, till the area again prior to installing the planting mix. I. Installation of Organic Matter Layer (NOTE: In Areas of Tree, Shrub, or Flower Planting but not in lawn areas, it is usually beneficial to increase the organic content in the very top layer of the soil. Iris effectively builds an 0 or A horizon in the soil, that may otherwise have been removed, without creating a shrinking soil that often results from adding high levels of organic matter in the entire soil depth.) A. After the specified topsoil or planting mi is installed and just prior to fine grading and the installation of tree, shrub, or flower plantings, spread 100 mm (4 in.) of organic matter over all bed areas designated on the drawings and rototill into the top 100 mm (4 in.) of the planting mix or tpsoil. B. Allow the finished grades to remain 50 to 75 mm (2-3 in.) higher than the grades on the grading plan to anticipate settlement over the first year. At the end of the planting guarantee period, reset the grades in this area, if required, to the final grades shown on the grading plan. IV. Fine Grading A. Grade the surface of all planted or lawn areas to meet the grades shown on the drawings after the 12- month settling period. Set grades at time of installation high enough relative to the type of soil mixand settlement anticipated so that the soil will be at the correct grades after the settlement period. Adjust the finish grades to meet field conditions as directed. 1. Provide for positive drainage from all areas toward the existing inlets and drainage structures. 2. Provide smooth transitions between slopes of different gradients and direction. Modify the grade so that the finish grade is flush with all paving surfaces or as directed by the drawings. B. Fill all dips and remove any bumps in the overall plane of the slope. 1. The tolerance for dips and bumps in lawn areas shall be a 12mm (1 /2 in.) deviation from the plane in 3,000 mm (10 ft). 2. The tolerance for dips and bumps in shrub planting areas shall be a 25mm (1 in.) deviation from the plane in 3,000 mm (10 ft). 3. All fine grading shall be inspected and approved by the landscape architect prior to planting, mulching, sodding, or seeding. V. Planting Operations A. Plants shall be set on flat -tamped or unexcavated pads at the same relationship to finished gradeas they were to the ground from which they were dug, unless otherwise noted on the drawings. Plants must be set plumb and braced in position until topsoil or planting mix has been placed and tamped around the base of the root ball. Improper compacting of be soil around the root ball may result in the tree settling or leaning. Plants shall be set so that they will be at the some depth and so that the root ball does not shift or move laterally one year later. (NOTE: Proper planting depth requires the root flare to be at or slightly above the finished grade. It is important to determine how deep the root flare is in the ball before it is placed in the planting hole. Sometimes the top of the ball may need to be raised until the root flare is at the proper planting depth and/or soil must be removed from the top of the ball.) 1. Determine the elevation of the root flare and ensure that it is planted at grade. This may require that the tree be set higher than the grade in the nursery. 2. If the root flare is less than 50 mm (2 in.) below the soil level of the root ball, plant at the tree the appropriate level above the grade to set the flare even with the grade. If the flare is more than 50 mm (2 in) at the center of the root ball the tree shall be rejected. B. Lift plants only from the bottom of the root balls or with belts or lifting harnesses of sufficient width not to damage the root balls. Do not lift trees by their trunk or use the trunk as a lever in positioning or moving the tree in the planting area. C. Remove plasfc, paper, or fiber pots from containerized plant material. Pull roots out of the root mat, and cut circling roots with a sharp knife. Loosen the potting medium and shake away from the root mat. Immediately after removing the container, install the plant Bch that the roots do not dry out. Pack planting mix around the exposed roots while planting. D. The roots of bare -root trees shall be pruned at the time of planting to remove damaged or undesirable roots (those likely to become a detriment to future growth of the root system). Bare -root trees shall have the roots spread to approximate the natural position of the roots and shall be centered in the planting pit. The plantirtg soil backfill shall be worked firmly into and around the roots, with care taken to fill in completely with no air pockets. E. Cut ropes or strings from the top of shrub root balls and trees smaller than 3 in. caliper after plant has been set. Remove burlap or cloth wrapping and any wire baskets from around top half of balls. Do not turn underond bury portions of burlap at top of ball. 1. Do not immediately remove the ropes and burlap from trees larger than 3 in. caliper. Return to each tree three months after planting (six months for fall -planted material), and cut all ropes around the trunks and tops of the root balls of these trees. 2. Completely remove any waterproof or water -repellant strings or wrappings from the root ball and trunk before backfilling. F. Set balled and Burlapped trees in the hole with the north marker facing north unless other wise approved by the landscape architect. (NOTE: Containerized material may not have a north orientation due to movement during the production process.) G. Place native soil, topsoil, or planting mix into the area around the tree, tamping lightly to reduce settlement. 1. For plants planted in individual holes in existing soil, add any required soil amendments to the soils, as the material is being backfilled around the plant. Ensure that the amendments are thoroughly mixed into the backfill. 2. For plants plantedn large beds of prepared soil, add soil amendments during the soil installation process. 3. When required by the landscape architect, add biostimulants at the time of planting in the area directly around the plant rootball. (NOTE: The landscape architect rruast amend these specifications to include Biostimulants.) 4. Ensure that the backfill immediately around the base of the root ball is tamped with foot pressure sufficient to prevent the root ball from shifting or leaning. H. Thoroughly water all plants immedidely after planting. Apply water by hose directly to the root ball and the adjacent soil. I. Remove all tags, labels, strings, etc. from all plants. J. Remove any excess soil, debris, and planting material from the job site at the end of each workday. K. Form watering saucers 100 mm (4 in.) high immediately outside the area of the root ball of each tree as indicated on the drawings. VI. Staking and Guying A. Stake or guy a tree only when necessary for the specific conditions encountered and with the approval of the landscape architect. Staking may be required in unusual circumstances such as sandy soils in either the root ball or adjacent soils or in extremely windy locations. Poor -quality trees with cracked, wet, or loose root balls, poorly developed trunk -to -crown ratios, or undersized root balls shall be rejected if they require staking, unless written approval to permit staking or guying as a remedial treatment is obtained from the landscape architect. Trees that settle out of plumb due to inadequate soil compacibn either under or adjacent to the root ball shall be excavated and reset. In no case shall trees that have settled out of plumb be pulled upright using guy wires. B. When required, staking and guying methods shall be approved by the landscape architect. If no staking or guying requirements appear on the drawings, submit for approval a drawing of the staking or guying method to be used. Stakes, anchors, and wires shall be of sufficient strength to maintain the tree in an upright position that overcomes the particular circumstances that initiated the need for staking or guying. Guy wires shall be galvanized, multistrand, twisted wire. C. Where guy wires are attached around the tree, the trunk shall be protected with 20 - mm (3/4 in.) diameter rubber hose, black in color, and of sufficient length to extend past the trunk by more than 105 mm (6 in.). D. Stakes and guys shall be installed immediately upon approval or planting, and shall be removed at the end of the first growing season. Any tree that is not stable at the end of this time shall be rejected. VII. Wrapping A. Wrap the trunk of any tree only when necessary for the specific conditions encountered and with the approval of the landscape architect. Wrapping may be required for thin -barked species in unusual circumstances such as trees planted adjacent to South -or West -facing reflective surfaces, or when it is impossible to plant the tree with the trunk oriented to the some north orientation that it held in the growing nursery. B. When required, wrapping methods shall be approved by the landscape architect. If no wrapping requirements appear on the drawings, submit for approval a drawing of the wrapping method to be used. Wrapping material shall be as specified in this specification. Wrapping material shall be fastend using a biodegradable tape. All tape shall be loosely wrapped around the wrapping material in single layer to permit its breakdown in sunlight and permit a minimum of 25 mm (1 in.) of unrestricted trunk growth. Stapling or tying the wrap with non- or slowly biodegradable tape or any synthetic or natural fiber string shall be prohibited. C. Wrapping material shall be applied from the base of the tree to the first branch. D. All wrapping material shall be removed no later than at the end of the year after planting or as specified by the landscape architect. VIII. Pruning A. Plants shall not be heavily pruned at the time of planting. Pruning is required at planting time to correct defects in the tree structure, including removal of injured branches, double leaders, waterspouts, suckers, and interfering branches. Healthy lower branches and interior small twigs should not be removed except as necessary to clear walks and roads. In no case should more than on-equarter of the branching structure be removed. Retain the rmrmal or natural shape of the plant. B. All pruning shall be completed using clean, sharp tools. All cuts shall be clean and smooth, with the bark intact with no rough edges or tears. C. Except in circumstances dictated by the needs of specific pruning practiT.s, tree paint shall not be used. The use of tree paint shall be only upon approval of the landscape architect. Tree paint, when required, shall be paint specifically formulated and manufacturing for horticultural use. X. Mulching A. All trees, shrubs, and other plantings will be mulched with mulch previously approved by the landscape architect. The mulch on trees and shrubs shall be to the depths shown on the drawing. Mulch must not be placed within 8 cm (3 in.) of the trunks of trees or shrubs. X. Maintenance of Trees, Shrubs, and Vines A. Maintenance shall begin immediately after each plant is planted and continue until its acceptance has been confirmed by the landscape architect/owner. B. Maintenance shall consst of pruning, watering, cultivating, weeding, mulching, tightening and repairing guys and stakes, resetting plants to proper grades or upright position, restoring of the planting saucer, and furnishing and applying such sprays or other materials as necesary to keep plantings free of insects and diseases and in vigorous condition. C. Watering: Contractor shall irrigate as required to maintain vigorous and healthy tree growth. Overwatering or flooding shall not be allowed. The contractor shall monitor, adjust, and use existing irrigation facilities, if available, and furnish any additional material, equipment, or water to ensure adequate irrigation. Root balls of all trees and large shrubs shall be spot watered using XI. Acceptance A. The landscape architect shall inspect all work for acceptance upon written request of the contractor. The request shall be received at least ten calendar days before the anticipated date of inspection. B. Acceptance of plant material shall be for general conformance to specified size, character, and quality and shall not relieve the contractor of responsibility for full conformance to the contract documents, including correct species. C. Upon completion and re -inspection of all repairs or renewals necessary in the judgment of the landscape architect, the landscape architect shall certify in writing that the work has been accepted.

METHODS Psomas Certified Arborist Trevor Bristle (International Society of Arboriculture [ISA] Certificate No. WE-10233A) visited the Project site on February 12, 2026, to document the type, quantity, and condition of trees present on the Project site. The condition of each tree was evaluated by carefully examining the trunk, branches, and foliage. During the survey, the following data were recorded: tree species, number of trunks, trunk Diameter at Breast Height (DBH, measured at 4.5 feet above ground level), tree height, canopy diameter, and qualitative assessment ratings of aesthetics and health. A metal identification tag was affixed to each tree on the north side of the trunk at DBH where access was possible. Tree locations were recorded on a hand-held tablet GPS device. REGULATORY AUTHORITY Chapter 22.38 of the City of Diamond Bar Municipal Code regulates tree protection and preservation related to the removal, relocation, or pruning of "protected trees". If a project proposes to remove trees or if construction is proposed within the drip line of a "protected tree", a tree permit is required and the tree shall be replaced with another protected species. Required replacement ratios vary depending on the property size and the type of the proposed development. "Protected trees" that are removed from residential properties less than 20,000 square feet are to be replaced at a minimum ratio of 2:1. "Protected trees" removed from residential parcels greater than 20,000 square feet and all commercial and industrial properties are to be replaced at a minimum of 3:1 ratio. The size of 150 South Arroyo Parkway replacement trees shall be determined by the City of Diamond Bar. Suite 102 Pasadena, CA 91105 Tel 626.351.2000 www.Psomas.com Page 84 of 127 Visanu & Radhika Chawla c/o Terry Young Ch February 26, 2026 Page 2 The Municipal Code defines "protected trees" as: • Native oak (Quercus sp.), walnut (Juglans californica), sycamore (Platanus racemosa), and willow (Salix sp.) trees with a DBH of eight inches or greater; pepper tree (Schinus molle) with a DBH of eight inches or greater where appropriate; • Trees of significant historical or value as designated by the council; • Any tree required to be preserved or relocated as a condition of approval for a discretionary permit; • Any tree required to be planted as a condition of approval for a discretionary permit; and • A stand of trees, the nature of which makes each tree dependent upon the others for survival. In addition to the "protected trees", all trees on the Project site were requested to be inventoried per City Planning Division Development Review No. PL2025-27. Trees that are exempted from the regulations of the Municipal Code include: • Trees, except those designated by the city council as a historical or cultural tree and trees required to be preserved, relocated, or planted as a condition of approval of a discretionary permit, located on all developed properties prior to adoption of the Development Code; • Trees held for sale by licensed nurseries or tree farms; • Hazardous trees that present a threat to other protected trees, structures, or public safety; • Trees within public rights -of -way where their removal, pruning or relocation is necessary to obtain adequate line -of -site distances or to keep streets and sidewalks clear of obstructions as required by the city engineer. • Trees that interfere with a public utility; • The pruning of branches not to exceed four inches in diameter; • Native oak, walnut, sycamore, willow, or pepper trees located on a lot one-half acre or less; and • Any native oak, walnut, sycamore, willow or naturalized California Pepper trees planted subsequent to the subdivision of a property. RESULTS A total of 96 trees were documented on the Project site. These trees are along the perimeter of the Project site and throughout the backyard. Of the documented trees, 28 meet the definition of a "protected tree" per the Municipal Code. These include 17 Southern California black walnuts (Juglans califamica), 10 coast live oaks (Quercus agrifolia), and 1 Inland scrub oak (Quercus berberidifolia). A summary of tree data is available in Table 1 and all collected tree data is summarized in Attachment A. Page 85 of 127 Visanu & Radhika Chawla c/o Terry Young Ch February 26, 2026 Page 3 Tree locations are shown on Exhibit 2 and photographs of all trees on the Project site are provided in Attachment B.

Trees in poor health typically show one or more of the following symptoms: damage to the trunk or branches, atypical foliage, insect infestation, extreme lean, rot, fungal fruiting bodies, or poor structure. One coast live oak (Tree No. 20) was given a very poor health rating (though not considered hazardous to exempt it from the regulations). This is a small tree with brittle branches, yellowing foliage, and poor branch structure. This tree is expected to continue to decline due to its current health status. IMPACTS Based on a review of the proposed construction footprint, 28 trees occur within the Project construction area and will be removed (Exhibit 3). An additional 6 trees (Trees 30, 31, 32, 40, 41, and 42) are located immediately adjacent to the Project construction area and will have their root zones encroached upon (i.e., ground disturbance within a tree's dripline [i.e., outer canopy edge]). Of the trees to be removed, 8 meet the criteria for "protected tree" status, consisting of 7 Southern California black walnuts and 1 coast live oak. Among encroachment trees, 3 are considered protected, consisting of 1 Southern California black walnut and 2 coast live oaks. Table 2 provides a summary of expected tree impacts associated with Project implementation.

DBH: diameter at breast height; in: inches; ft: feet Based on requirements in the Municipal Code, mitigation for Project impacts on "protected trees" will require tree replacement at a 3:1 ratio. Therefore, a total of 24 replacement trees are required to offset impacts to trees that will be removed. In addition to the trees to be directly removed, the 6 trees to be encroached upon may require replacement planting to offset this impact. Replacement planting should be required if an arborist determines during Project construction that this encroachment would be expected to cause a significant decline in tree health. Consultation with the City of Diamond Bar is recommended to determine the final requirements for tree replacement planting. Page 87 of 127 Visanu & Radhika Chawla c/o Terry Young Ch February 26, 2026 Page 5 TREE PROTECTION DURING CONSTRUCTION The "protected trees" that are to remain may be impacted by construction activities without adequate protection measures. Construction may result in grade changes (i.e., cut and fill), soil compaction, airborne dust, and altered drainage patterns that may negatively affect tree health. The following tree protection measures are recommended during construction based upon the proximity to existing "protected trees". 1. Existing trees to be retained shall be enclosed by chain link fencing with a minimum height of five feet or by another protective barrier approved by the City director prior to the issuance of a grading or building permit and prior to commencement of work. 2. Barriers shall be placed at least five feet outside of the drip line of trees to be protected. A lesser distance may be approved by the City director if appropriate to the species and the adjacent construction activity. 3. No grade changes shall be made within the protective barriers without prior approval by the City director. Where roots greater than one inch in diameter are damaged or exposed, the roots shall be cleanly saw cut and covered with soil in conformance with industry standards. 4. Excavation or landscape preparation within the protective barriers shall be limited to the use of hand tools and small hand-held power tools and shall not be of a depth that could cause root damage. 5. No attachments or wires other than those of a protective or nondamaging nature shall be attached to a "protected tree". 6. No equipment or debris of any kind shall be placed within the protective barriers. No fuel, paint, solvent, oil, thinner, asphalt, cement, grout or any other construction chemical shall be stored or allowed in any manner to enter within the protected barrier. 7. If access within the protection zone of a protected tree is required during the construction process, the route shall be covered in a six-inch mulch bed in the drip line area and the area shall be aerated and fertilized at the conclusion of the construction. 8. When the existing grade around a protected tree is to be raised, drain tiles shall be laid over the soil to drain liquids away from the trunk. The number of drains shall depend upon the soil material. Lighter sandy soils and porous gravelly material required fewer drains than heavy nonporous soils like clay. Dry wells shall be large enough to allow for maximum growth of the tree trunk. Dry well walls shall be constructed of materials that permit passage of air and water. 9. When the existing grade around a tree is to be lowered, either by terracing or a retaining wall, a combination may be used to lower grade. With either method, the area within the drip line shall be left at the original grade. The retaining wall shall be porous to allow for aeration. 10. Trees that have been destroyed or that have received major damage during construction shall be replaced prior to final inspection. Page 88 of 127 Visanu & Radhika Chawla c/o Terry Young Ch February 26, 2026 Page 6 11. An arborist may be required by the City to monitor construction activities within, or nearby, "protected trees" drip line protection zone. 12. Pruning of any branches greater than three inches in diameter or removal of more than ten percent of the total canopy shall be overseen by a Certified Arborist. 13. Any trees that are to be retained on site but are damaged by construction activities (e.g., soil disturbance within the drip line or excessive pruning) should be monitored for a period of at least two years to detect any health impacts that may require additional tree replacement. RECOMMENDATIONS 1. Consultation should be initiated with the City of Diamond Bar to identify appropriate tree placement/mitigation strategies. 2. At the conclusion of construction activities, a post -construction site survey should be conducted to confirm the number of trees removed and any subsequent impacts. DISCLAIMER Trees were mapped using a hand-held GPS device in order to locate each tree as accurately as possible. However, tree canopy cover on the Project site naturally limits the accuracy of such devices. While care was taken to record the most accurate location possible and tree locations are felt to be generally accurate, tree locations depicted in Exhibits 2 and 3 should be treated as approximate locations. Therefore, the ultimate impact that the proposed Project will have on protected trees will not be known until construction is complete. Psomas appreciates the opportunity to assist with this Project.
