Hereinafter in this resolution, the subject Development Review shall collectively be referred to as the "Project." 2.

On January 24, 2012, 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, 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 22.52, this Planning Commission hereby finds as follows: Development Review Findings (DBMC Section 22.48.040) 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 and layout of the proposed 10,414 square -foot single family residence with two attached three -car garages totaling 1,888 square feet is consistent with the City's General Plan, City Design Guidelines and development standards with exception except for the front setback. The architectural style is a Mediterranean design and also provides earth -tone shades for the exterior finish to soften the building's visual impact and assist in preserving the hillside's aesthetic value. 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 residence 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 home will riot 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 grades. 3. The architectural design of the proposed development is compatible with the character of the surrounding neighborhood and will maintain and enhance the 2 Planning Commission Resolution No. 2012-04 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 new single-family home is designed to be compatible with the character of the eclectic neighborhoods in The Country Estates. It is designed in the Mediterranean style of architecture with earth -tone shades for the exterior finish to soften the building's visual impact and assist in preserving the hillside's aesthetic value. 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 new single-family home is a Mediterranean style of architecture. Variation in the building elements has been achieved through the utilization of varying architectural features, building materials, and landscaping. 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 a// conditions within the approved resolution, and the Building and Safety Division and Public Works Departments, and Los Angeles County Fire 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. Minor Variance Findings 32.040) 1 There are special circumstances applicable to the property (e.g., location, shape, size, surroundings, topography, or other conditions), so that the strict application of the City's Development Code denies the property owner privileges enjoyed by other property owners in the vicinity and under identical zoning districts or creates an unnecessary and non -self created, hardship or unreasonable regulation which makes it obviously impractical to require compliance with the development standards; 3 Planning Commission Resolution No. 2012-04 The Minor Variance is a request to reduce the front yard setback from a required minimum of 30 feet to 24 feet. The project site has a steep natural average slope of 25%, making it imperative for the project to stay as close to the street as possible in order to minimize the number of retaining walls and the amount of fill material that will be imported to create the building pad. To achieve the required depth of the front yard a substantial amount of additional grading will be required and additional retaining walls would have to be constructed, which conflicts with the City's goal to maintain as much of the environment as possible in a natural state. In light of these facts, the granting of the requested Minor Variance is an appropriate means to help achieve this goal. 2. Granting the Variance is necessary for the preservation and enjoyment of substantial property rights possessed by other property owners in the same vicinity and zoning districts and denied to the property owner for which the Variance is sought; The granting of the requested Minor Variance will allow the subject property to be developed and used in a manner similar to that which is enjoyed by other properties in the vicinity which are not similarly encumbered by the topographical conditions constraining the subject property. 3. Granting the Variance is consistent with the General Plan and any applicable specific plan; The Minor Variance is consistent with the General Plan. A goal of the General Plan is to preserve the environment in a natural state when possible. The granting of the Minor Variance will substantially reduce the amount of grading needed to create a building site. 4. The proposed entitlement would not be detrimental to the public interest, health, safety, convenience, or welfare of the City; and The requested minor variance affects only the property in question. The reduction in the front yard setback is consistent with the development techniques used in similar situations. 5. The proposed entitlement 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) (New Construction of One 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: 4 Planning Commission Resolution No. 2012-04 1 Development shall substantially comply with the plans and documents presented to the Planning Commission at the public hearing regarding this proposed project. 2.
