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 Municipal Code (DBMC) Sections 22.48 and 22.38, this Planning Commission hereby finds as follows: Development Review Findings (DBMC Section 2248.040) 1. 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. An italianate architectural design is being proposed with earth tone shades for the exterior finish as not to detract from the hillsides. From the street view, the building has the appearance of a two-story structure, while the rear of the building steps down to three levels. 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, window and door placement, and the 2 PC Resolution No. 2021-07 proposed exterior finishes of the single-family residence incorporates various details and architectural elements such as low-pitched hipped s-tile roof, precast concrete stone columns and balusters, arched windows with crown molding, earth -toned smooth stucco and stone veneer. All elevations are architecturally treated and strongly articulated 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 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 home are well balanced and appropriate for the 0.7 gross -acre site. The Italianate architectural style with earth tone shades for the exterior finish 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. 3 PC Resolution No. 2021-07 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 design of the proposed home is Italianate with architectural elements such as low-pitched hipped s-tile roof, precast concrete stone columns and balusters, arched windows with crown molding, earth -toned smooth stucco and stone veneer. The new home will not be intrusive to neighboring homes. Earth -tone shades for the exterior finish are used to soften the building's visual impact and assist in preserving the hillside's aesthetic value. 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 The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) asset forth under Article 19 Section 15303(a) (construction of a new single-family residence) of the CEQA Guidelines. Tree Permit Finding (DBMC Section 22.38.110) 1. The tree is a public nuisance by causing damage to improvements (e.g., building foundations, retaining walls, roadways/driveways, patios, and decks) and appropriate mitigation measures will be implemented in compliance with DBMC Section 22.38.140 (Tree protection requirements) below. The applicant submitted a tree report, prepared by a licensed arborist in December 2020. There are four trees on site that are considered protected, including two California sycamores with a DBH of 34 and 44 inches, one coast live oak with a DBH of 20 inches, and a multi -trunk California black walnut with a DBH of four to eight inches. Two protected trees in fair health will remain on the property. one California sycamore (Tree #1) and California black walnut (Tree #6). These trees will be retained and protected in place with protective, 4 PC Resolution No. 2021-07 chain -link fencing to be installed prior to construction activities. Four trees that are in fair to poor health are proposed for removal: one London plane (Tree #2), one California pepper (Tree #5), one protected California sycamore (Tree #3) and one protected coast live oak (Tree #4). These trees are located in or near areas of construction and cannot be preserved. The protected trees will be replaced at a 3:1 ratio with six 24-inch box coast live oak trees at the rear of the property, which is the required amount of mitigation trees to be planted. The planting of six new protected species will provide sufficient replacement of the natural landscape.
