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. 2. The Planning Commission hereby determines that the proposed project is categorically exempt from the requirements of the California Environmental Quality Act of 1070 (CEQA) in accordance to Sections 15303 and 15332 of the CEQA Guidelines. 3. Based upon the information contained in the submitted plans, the associated staff report and testimony given at the public hearing the Planning Commission hereby finds as follows: DEVELOPMENT REVIEW a. The design and layout of the proposed development is consistent with the General Plan, development standards of the applicable zone district, design guidelines, and architectural criteria for specialized areas (e.g., specific plans, community plans, boulevards, or planned developments.) The proposed single-family residence and accessory structures are consistent with the RR zone's Development Standards and the City's Design Guidelines, In addition, the proposed project, with conditions of approval; is consistent with the surrounding single- family dwelling units in terms cf mass; scale and appearance. b. The design and layout of interfere with the use and future development, and it hazards. the proposed development will not enjoyment of neighboring existing or will not create traffic or pedestrian The subject property is located within a designed and developed residential estate neighborhood. The existing public and private improvements are available to support the proposed development and the surrounding neighborhood. The proposed single-family residence will not negatively impact the existing or future development of the surrounding neighborhood. 2 Planning Co-nmission ReSOlutiOri No. 2007-43 c. The architectural design of the proposed development is compatible with the characteristics of the surrounding neighborhood and will maintain the harmonious, orderly and attractive development contemplated by Chapter 22.48 Diamond Bar Development Code, the General Plan, City Design Guidelines, or any applicable specific plan. The design of the proposed single-family residence and accessory structure is consistent with the terms and conditions of the long- range planning policy documents adopted by the City of Diamond Bar. The proposed project is compatible with the scope, scale and appearance of the surrounding existing homes. The proposed project is an infill development that will complete the neighbonccod residential character. d. 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, and color that will remain aesthetically appealing. The project's design and use of construction material are consistent with other single-family residences in the neighborhood. e. The proposed project will not be detrimental to the public health, safety, or welfare or materally in;urious (e.g., negative affect on property values or resale(s) of property) to the properties or improvements in the vicinity. The proposed single-family residence is consistent with the anticieated development pattern for the neighborhood and it will not negatively impact the public health, safety or general welfare. VARIANCE a. There does not exists special circumstances applicable to the property so that the strict application of this 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 Plarn ro Commission Resolution No. 2007-43 A design alternative prepared by the project designers demonstrate that the conceptual grading plan can be reasonably modified to reduce the heights of the retaining walls in question to eight (8) feet without creating other conflicts with the Hillside Management Ordinance, or reducing building area or usable private outdoor living space as proposed on the submitted plans. Moreover, the design alternative demonstrates that the garage and guest parking areas can be reasonably accommodated by a total of two drive approaches, rather than three. Granting the variance is not necessary for the preservation and enjoyment of substantial property rights possessed by other property owners in the same vicinity and zoning district and denied to the property owner for which the variance is sought. The topography of the subject property lends itself to the concept of providing subterranean parking. Access to the parking facilities requires a deep cut into the existing topography for the driveway only. The subterranean parking is a concept consistent with the goals of the City's Hillside Development Standards whereas the height of the dwelling and the rear yard retaining walls will be reduced in height. However, consistency with the Hillside Development Standards can still be achieved if a combination of practicable grading techniques is employed to reduce the heights of the sideyard retaining walls to eight (B) feet. The guest parking area can be designed with a single driveway and still provide convenient off-street parking for houseguests. Granting the variance is consistent with the general plan and any applicable specific plan. The proposed increased heighi of the retaining will not have an impact on the General Plan in that the exposed face of the retaining wall will face the interior of the subject property and cannot be easily seen from adjoining parcels of land. The proposed additional driveway is at odds only with the Diamond Bar Development Code, and would not have an impact on the City's General Plan. d. The proposed entitlement would not be detrimental to the public interest, health, safety, convenience or welfare of the city. 4 Manning Commission Resolution No. 2007-43 The public welfare and safety will not be impacted by the increase height of the proposed retaining walls or the number of driveway approaches, and are not factors when deliberating on whether or not to grant this variance request. 4. Based upon the findings and conclusion set forth above, the Planning Commission hereby denies Variance No. 2007-06. 5. Based upon the findings and conclusion set forth above, the Planning Commission hereby approves Development Review No. 2007-08, and directs the Community Development Director to grant a Minor Variance to allow the side yard retaining walls to be increased to eight (8) feet, as depicted in Exhibits 1 b and 2b of the plans associated with the Application on file with the Planning Division, subject to the following conditions: a.
