A. RECITALS The property owner and applicant, Michael Wu, has filed an application for Development Review No. PL2021-51 to construct a new 3,320 square -foot, three -level, single-family residence with a 561 square -foot attached garage, 538 square feet of outdoor deck area, 1,407 square feet of terrace areas, rear yard improvements, and a 999 square -foot, attached accessory dwelling unit (ADU), located at 1198 Chisolm Trail Drive, Diamond Bar, County of Los Angeles, California. 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 13,036 gross square feet. It is located in the Low -Medium Density (RLM) zone with an underlying General Plan land use designation of Low Density Residential. 3. The legal description of the subject property is Lot 14 of Tract No. 37873. The Assessor's Parcel Number is 8717-026-013. 4, On July 12, 2024, 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 July 12, 2024. A notice display board was posted at the site, and a copy of the notice was posted at the City's designated community posting sites. 5. On July 23, 2024, 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: 1. 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 under 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) Section 22,48, 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 Cify'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. Site grading is limited to areas in proximity to the residence, preserving some of the site's unimproved natural slope at the rear of the property. Where retaining walls are required, the exposed portions of retaining walls will consist of decorative light gray split -face block 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. All elevations are architecturally treated and strongly articulated through projections along the visible fagade [City's Design Guidelines 8. Architecture (3)]. Additionally, the design includes deck/balcony areas projecting from the wall fagade, which further contributes to articulation. The Project complies with all development standards of the Low -Medium Density 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 ADU 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. PC Resolution No. 2024-OS As seen from the street, the adjacent property to the south located at 1196 Chisolm Trail Drive has a similar building profile to the proposed residence. Both adjacent properties will continue to overlook open space areas from their rear yards. 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 complies with 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 project site is in a neighborhood with existing two-story residences and one recently approved three-story residence. The three-story residence was approved by the Planning Commission under Development Review No. PL2023- 05 on March 26, 2024, for the adjacent lot to the north located at 1200 Chisolm Trail Drive. Similar to the approved residence, the proposed residence has been carefully designed to blend with the natural terrain and preserve the character and profile of the natural slope, resulting in a well-balanced residence with similar visible mass and scale when compared with other existing residences in the neighborhood. The Project minimizes negative impacts on surrounding uses since the house will not block existing views from adjacent properties. The average size of existing residences within a 500-foot radius is approximately 2,312 square feet, with the largest at 3,434 square feet. With the addition of the recently approved single-family residence located at 1200 Chisolm Trail Drive, the average size increases to Z377 square feet and the approved residence becomes the largest home at 4,310 square feet, At 3,320 square feet, the proposed residence is 990 square feet smaller than the approved residence located at 1200 Chisolm Trail Drive. The combined size of the proposed residence with the ADU is 4,319 square feet and exceed the size of all other would homes in the neighborhood. However, all residential lots in Diamond Bar that are not currently developed with an ADU may construct at least an 800 square -foot ADU (maximum 1,000 square feet), potentially increasing the average home size to 3,377 square feet and the largest home size to 5,310 square feet. '3 PC Resolution No. 2024-08 Furthermore, the proposed residence appears to be similar in size to other residences. This similarity is due to a split pad design which limits the visibility of the lowest level of the three-story residence. The lowest level is located on a building pad below the street and will not be directly visible from street level. The design softens the massing and reduces the scale of the building. Additionally, architectural treatment, window/door placements, varying setbacks and projections contribute to a less massive building form. As a result, the proposed home is compatible in mass and scale to other homes in the neighborhood. The proposed eclectic architecture with Mediterranean influences will be visually compatible with other homes in the neighborhood, which are predominantly ranch -style tract housing. Ranch -style tract homes are characteristically -similar with exterior painted stucco walls, careful placement of wood or stone veneer for visual interest and lack of excessive ornamentation. Additionally, a vibrant landscaping palette with a combination of trees and shrubs are proposed, which will provide screening and a soft transition between the subject property and the neighboring properties. In summary, the proposed project fits the scale and architectural character of the existing neighborhood. 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 architectural style is eclectic with Mediterranean influences. The applicant designed the project to have elements to reflect the architectural style, including the following design features: • Low -pitch (3:12 pitch) hipped concrete the roof with varying heights to break up the roof massing; Exterior fagade consisting of painted stucco and pre -cast ledgestone veneer, with the use of projections and articulation; • A front entryway supported by pre -cast concrete columns, above a wrought iron/glass front door; • Vinyl windows of various sizes and configurations with surrounds; Transparent glass balcony railings and bronze aluminum terrace railings; and • Simple color scheme, which includes tan stucco walls and earthen brown ledgestone veneer in combination with a gray/brown color -blended tile roof. Windows, door trims/surrounds and fascia include variations of brown, beige and gray, which complements the neutral color tones of the walls and roof. Q PC Resolution No. 2024-08 The residence maintains a degree of architectural quality and visual interest without the need for excessive ornamentation, which is consistent with the proposed architectural style. 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 Department 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. Based upon the findings and conclusion set forth above, the Planning Commission hereby approves this Application, subject to the following conditions: 1. Development shall substantially comply with the plans and documents presented to the Planning Commission at the public hearing. 2.
