The applicant is concurrently proposing the construction of a 798 square -foot, attached Accessory Dwelling Unit (ADU). Although it is depicted on the project plans, the attached ADU is permitted by right, and is not subject to Planning Commission review. RECOMMENDATION: Adopt the attached Resolution (Attachment A) approving Development Review Planning Case No. PL2025-47, based on the findings of Diamond Bar City Code (DBCC) Sections 22.48, subject to conditions. BACKGROUND: The project site is located in the Diamond Bar Country Estates (The Country), on the northwest side of Shadow Canyon Drive, east of Steeplechase Lane. The property was developed in 1972 with a 2,248 square -foot single - story home and an attached 617 square -foot three -car garage. There are no protected trees onsite. The proposed project has been approved by the Diamond Bar Country Estates Architectural Committee on December 8, 2025. Page 22 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 The property is legally described as Lot 63 of Tract No. 30289, and the Assessor's Parcel Number (APN) is 8713- 018-035. Site and Surrounding General Plan, Zoning and Land Uses The image below highlights the subject property: Site (Plan View) Aerial Page 23 of 72 Agenda Item It: 5.1 Meeting Date: May 26, 2026 Ow Project Site Adjacent Property to the North Page 24 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 Adjacent Property to the South The following table summarizes the land use status of the subject property and its surroundings: General Designation Zoning. - Site Rural Residential RR Single -Family Residential North Rural Residential RR Undeveloped South Rural Residential RR Undeveloped East Rural Residential RR Single -Family Residential EWest Rural Residential RR Single -Family Residential Project Description Site Plan As stated, the property's gross lot area is 42,689 square feet (0.98 gross acres), which includes a 27-foot wide private street easement along the frontage of Shadow Canyon Drive. The property is an irregular -shaped lot with a net buildable area (i.e., minus the private street easement, flood hazard area, and drainage easement) of 31,360 square feet (0.72 net acres). It is a hillside property with a descending slope at 23.24 percent that starts from the private street easement to the rear property line. The existing house is situated 26'-6" from the edge of the private street easement line along Shadow Canyon Drive. The entrance to the residence faces Shadow Canyon Drive and a 30'-5" wide driveway provides access to an existing three -car garage. Page 25 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 The addition will extend the existing footprint of the house towards the rear and north side of the property. The existing residence has a nonconforming front setback of 26'-6" (where 30 feet is required). As the front setback does not comply with current development standards, the residence is classified as a "nonconforming structure" pursuant to DBCC Section 22.68.030. Additions to nonconforming structures are permissible if they meet the following criteria pursuant to DBCC Section 22.68.030(b): 1) the addition or improvement conforms to all other applicable provisions of the DBCC and 2) the addition is limited to the first floor (i.e., the floor closest in elevation to the adjacent street grade). Grading Plan The applicant is proposing to fill 508 cubic yards and cut 73 cubic yards of soil throughout the property to create a buildable pad that can support the proposed addition and attached ADU. Therefore, 435 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 between 29 to 46 hauls. The proposed grading activities are limited to areas in proximity to the residence, preserving majority of the site's unimproved natural slope. The applicant is proposing two tiers of retaining walls, with a maximum height of four feet, at the rear of the property to accommodate the property's slope, support fills above the natural grade, and expand the buildable pad for the addition and ADU. All exposed portions of the proposed retaining walls will have a decorative finish, with the use of split -faced with brick caps to match the house. Architecture The house will undergo a complete exterior remodel as part of the proposed project. The remodel incorporates a contemporary interpretation of Mediterranean architectural elements including a low-pitched roof, simple rectilinear window and door openings, and stucco wall surfaces with a sand finish. Additional architectural elements include simple stucco door and window surrounds, metal light fixtures, and vinyl garage doors with embossed wood grain -textured panels. The exterior color palette utilizes warm, earth -toned hues to complement the hillside setting. Proposed North (Front) Elevation The proposed remodel and addition are comprised of the following components: • The floor plan consists of an extension of the existing family room, new common areas (dining room, kitchen, wok kitchen, pantry, theater room, recreation room, laundry room, one half bathroom and two full bathrooms) and three bedrooms (one with a bathroom and walk-in closet). The existing three -car garage will remain unchanged. Page 26 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 • A front entry porch totaling 119 square feet is proposed at the front of the residence. The floor area distribution is summarized below: PROJECT SUMMARY (square footage) Living Area 3,895 • First Floor (Existing) 2,248 • First Floor Proposed 1,647 Non -Livable Area 736 • Garage (Existing) 617 • Porch (Proposed) 119 TOTAL FLOOR AREA 4,631 The height of the building is increasing from 16'-7" feet to 21'-7", measured from the finished grade to the highest point of the roofline. Landscape Plan There are ten trees currently on -site. The applicant is proposing to remove three trees and plant five trees throughout the front and rear yard of the project site; four 24-inch box western redbuds and one 24-inch box Greek strawberry tree. To complement the five trees, various 15-gallon, 5-gallon, and 3-gallon shrubs that have a variety of color, texture, and form are proposed throughout the front, side and rear yards. The applicant will also be enhancing the parkway landscaping (the strip of landscaping that sits in the private street easement) by removing the dead grass and replacing it with artificial turf. 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. ANALYSIS: Review Authority The proposed project requires Planning Commission review and approval of a Development Review (DR) application. The analysis that follows provides the basis for staff's recommendation to approve the DR application. Development Review (DBCC Chapter 22.48) Additions which are equal to or greater than 50 percent of the existing habitable floor area of all existing structures on site, or substantially change the appearance of an existing residence, require Planning Commission approval of a DR application. Development Review approval is required to ensure compliance with the City's General Plan policies 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 Page 27 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 standards for residential development in the RR zone: • - • • 30 feet 26'-6" 26'-6" No* • - - • • 15 feet on one side, north side - 36'-2" north side - 81 '- 1 " Yes 10 feet on the other south side - 17'-6" south side - 10 feet • - 25 feet N/A - north side N/A - north side Yes** - - - N/A - south side N/A - south side - • - • • 25 feet 9 feet 25 feet Yes Maximum of 30% 9.38% 10.8% Yes • - 35 feet 16'-7" 21 '-7" Yes • 2-car garage 3-car garage 3-car garage Yes - 4-foot exposed 4-foot exposed 4-foot exposed Yes - (supporting fill) (supporting fill) (supporting fill) Minor Conditional Use Permit approval is not required pursuant to DBCC Section 22.68.030(b). *There are no residences existina or beina or000sed on the adiacent lots as of the date of this retort. 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 21'-7", where 35 feet is allowed; • Architectural treatment is provided on all sides of the building with varying setbacks and projections; • 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 Neighborhood The existing house is located on an existing flat pad and the addition will extend the existing footprint of the house towards the rear and north side of the property. The project site is located between two undeveloped lots. The proposed addition will not be intrusive to neighboring homes since the proposed addition will not block existing views from adjacent properties. The properties located to the north and south of the project site are currently undeveloped; therefore, the addition will have no view impacts from these properties. All properties located to the east, directly across the street from the project site, are situated on building pads at significantly higher elevations based on topographic data obtained from the City's GIS system. Because it is a single -story addition to an existing single -story residence, the project will not impact views from these properties. Page 28 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 The adjacent lots at 2845 and 2887 Shadow Canyon Drive will remain vacant, therefore, the closest neighboring property is the property located directly across the street from the project site at 2868 Shadow Canyon Drive. As stated previously, the proposed addition will be constructed on a lower building pad elevation comparable to the adjacent neighboring property located at 2868 Shadow Canyon Drive. As a result, the proposed addition will not exceed the height of neighboring homes, thereby maintaining the visual scale and grade levels of the adjacent homes along Shadow Canyon Drive. Aerial View of Project Site and Adjacent Properties In addition, maintaining privacy for surrounding properties was considered in the project's design. The existing home is situated between two vacant lots, and the only properties potentially affected by the proposed addition are the homes at 2840 and 2828 Steeplechase Lane, located nearest to the project site. Although these homes are at a lower elevation and their rear yards are within the line of sight of the project site, they are approximately 150 feet away from the proposed building footprint and are further screened by mature trees on their respective properties. As such, the project would not result in privacy impacts beyond what currently exist at this location. Page 29 of 72 Agenda Item #: 5.1 Meeting Date: May 26, 2026 Aerial View looking Northeast from Steeplechase Lane The proposed addition 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 addition 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 proposed addition will conform to all development standards, including building height, lot coverage and setbacks (with the exception of the existing nonconforming front setback) 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 remodel and addition 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 addition will not obstruct views of the vista for nearby properties. Additional Review The Public Works Department and Building and Safety Division reviewed this project, and their comments are included in the attached resolution as conditions of approval.

PL2025-47 TO REMODEL THE EXTERIOR AND CONSTRUCT A 1,647 SQUARE -FOOT FIRST -FLOOR ADDITION, A 119 SQUARE -FOOT FRONT ENTRY PORCH, AND AN INTERIOR REMODEL TO AN EXISTING 2,248 SQUARE -FOOT, SINGLE -STORY SINGLE-FAMILY RESIDENCE ON A 0.98 GROSS ACRE (42,689 GROSS SQUARE -FOOT) LOT LOCATED AT 2867 SHADOW CANYON DRIVE, DIAMOND BAR, CA 91765 (APN 8713-018-035). A. RECITALS The property owner, Na Dong, and applicant, Alan Gao, have filed an application for Development Review Planning Case No. PL2025-47 for a property located at 2867 Shadow Canyon Drive, Diamond Bar, County of Los Angeles, California, requesting Planning Commission approval to construct remodel the exterior and construct a 1,647 square -foot first -floor addition, a 119 square -foot front entry porch, and an interior remodel to an existing 2,248 square -foot single -story single-family residence. Hereinafter in this Resolution, the subject Development Review shall be referred to as the "Proposed Project." 2. The subject property is made up of one parcel totaling 42,689 gross square feet (0.98 gross acres). It is located in the Rural Residential (RR) zone with an underlying General Plan land use designation of Rural Residential. 3. The legal description of the subject property is Lot 63 of Tract No. 30289, and the Assessor's Parcel Number (APN) is 8713-018-035. 4. On May 15, 2026, public hearing notices were mailed to property owners within a 1,000-foot radius of the Project site. The notice was submitted to the San Gabriel Valley Tribune newspaper for publication on May 15, 2026. Also, public notices were posted at the project site and the City's designated community posting sites. 5. On May 26, 2026, the Planning Commission of the City of Diamond Bar conducted a duly noticed public hearing, solicited testimony from all interested individuals, and concluded said hearing on that date. B. RESOLUTION NOW, THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: Page 32 of 72 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 15301(e) (additions to existing structures) 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) Section 22.48, this Planning Commission hereby finds as follows: Development Review Findinas (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 the extent of grading impacts, the applicant is proposing approximately 508 cubic yards of fill and 73 cubic yards of cut in proximity of the residence to establish a buildable pad capable of supporting the proposed addition and rear yard improvements while preserving majority of the site's unimproved natural slope. All exposed portions of the proposed retaining walls will have a decorative finish, with the use of split -faced with brick caps to match the house as to not detract from the hillside. 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 a new entry porch. All elevations are architecturally treated and strongly articulated with the use of new colors and materials 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 Page 33 of 72 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 addition 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 Project will not be intrusive to neighboring homes since the proposed addition will not block existing views from adjacent properties. The properties located to the north and south of the project site are currently undeveloped, therefore, the addition will have no view impacts from these properties. All properties located to the east, directly across the street from the project site, are situated on building pads at significantly higher elevations based on topographic data obtained from the City's GIS system. Because it is a single - story addition to an existing single -story residence, the project will not impact views from these properties. The adjacent lots at 2845 and 2887 Shadow Canyon Drive will remain vacant, therefore, the closest neighboring property is the property located directly across the street from the project site at 2868 Shadow Canyon Drive. As stated previously, the proposed addition will be constructed on a lower building pad elevation comparable to the adjacent neighboring property located at 2868 Shadow Canyon Drive. As a result, the proposed addition will not exceed the height of neighboring homes, thereby maintaining the visual scale and grade levels of the adjacent homes along Shadow Canyon Drive. In addition, maintaining privacy for surrounding properties was considered in the project's design. The existing home is situated between two vacant lots, and the only properties potentially affected by the proposed addition are the homes at 2840 and 2828 Steeplechase Lane, located nearest to the project site. Although these homes are at a lower elevation and their rear yards are within the line of sight of the project site, they are approximately 150 feet away from the proposed building footprint and are further screened by mature trees on their respective properties. As such, the project would not result in privacy impacts beyond what currently exist at this location. The proposed addition 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; 3 Page 34 of 72 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 addition are well balanced and appropriate for the 0.98 gross -acre site. The Modern Mediterranean 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 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 existing residence will undergo a complete exterior remodel as part of the proposed project. The remodel incorporates a contemporary interpretation of Mediterranean architectural elements including a low-pitched roof, simple rectilinear window and door openings, and stucco wall surfaces with a sand finish. Additional architectural elements include simple stucco door and window surrounds, metal light fixtures, and vinyl garage doors with embossed woodgrain-textured panels. Through the use of earth -toned shades and quality materials that have texture and color, the proposed addition 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 addition 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 this Resolution, and with all other applicable 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.

Fenestration & Natural Light • Before: Window placement provides limited rhythm and natural light. • After: Fenestration is reconfigured to improve alignment, rhythm, and interior natural lighting. 4. Garage Integration • Before: Garage openings appear visually dominant and disconnected from the main fagade. • After: Garage elements are integrated through consistent materials and proportions, enhancing overall fagade continuity. 5. Architectural Cohesion • Before: Existing elements read as separate components with limited architectural unity. • After: The remodel establishes a cohesive architectural language across the entire structure. 6. Neighborhood Compatibility • Before: The existing building makes a limited contribution to the streetscape. • After: Without increasing visual bulk or altering residential use, the remodel improves curb appeal and streetscape quality while remaining compatible with surrounding homes.
