BACKGROUND: The project site is located in the Diamond Bar Country Estates (The Country), on the west side of Blaze Trail, south of Timbertop Lane. The site was developed in 1978 under Los Angeles County standards with a 3,282 square -foot single family residence and a 660 square -foot garage on a 1.47 gross acre (64,033 square -foot) lot. The property is legally described as Lot 140 of Tract No. 30578, and the Assessor's Parcel Number (APN) is 8713-028-022. The proposed addition consists of the following site plan and architectural components: Site Plan There are 25 native protected trees on site -22 California Live Oak and three Black Walnut trees. The applicant is proposing to remove five California Live Oaks trees and replace them with fifteen 24 -inch box Coast Live Oak trees at a 3:1 ratio. In addition, the applicant is proposing four terraced walls in the rear yard to create a 25 -foot rear pad to comply with the City's development standards for the rear setback. The existing structure has a nonconforming front setback of 19 feet, 10 inches. Although the existing structure is located within the required front setback, the proposed addition is located 30 feet from the front property line, and will not encroach into the required front setback. Architecture The proposed multi-level addition is primarily located at the rear and south side of the existing residence. The addition consists of the following components: Development Review No. PL 2012-529 * Patio/Balcony areas are not included as floor area The height of the existing home is 27 feet. The height of the proposed addition is 35 feet, measured from the finished grade to the highest point of the roofline on the third level. The existing architectural style of the home is California Ranch with gabled roofs, stucco walls, brick veneer, and vinyl windows. The applicant is proposing to change the design of the house to Mediterranean by adding hipped roofs, replacing the existing brick with stone veneer, replacing Cal --Shake roofing material with clay tiles, and wrought iron doors and window grilles. The applicant has obtained approval from The Diamond Bar Country Estates Association.

The following table describes the surrounding land uses located adjacent to the subject property: Development Review No. PL 2012-529 Page 3 of 12 Development Review No. PL 2012-529 Nage 4 of I ANALYSIS Review Authority (Diamond Bar Municipal Code (DBMCI Sections 22.48922.56922.38) The proposed project requires Planning Commission review and approval of three entitlement applications: Development Review, a Minor Conditional Use Permit, and a Tree Permit. ®evelo� erre Review J1JQggBgMiC Chapter 22.48) Additions that substantially change the appearance of an existing residence require Planning Commission approval of a Development Review (DR) application, Development Review approval is required to ensure compliance with the City's General Plan policies, development standards, 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 standards for residential development in the RR zone: Minor Conditional Use Permit is requested to allow the continuation of a nonCOIlTorming structure Decause ine auuitiuri is greater than 50 percent of the existing home and is not limited to the ground floor. See MCUP discussion on page 7 **The rear setback is measured from the rear of the building to the edge of the graded pad when the pad abuts a descending slope. Site and Grading Configuration: The project site is located on a rectangular shaped Development Review No. PL 2012-529 Page 5 of 12 property with a steep descending slope of 18% in the rear yard. The applicant i�� proposing to cut 12 cubic yards of soil and fill 2,950 cubic yards of soil to create a buildable pad towards the rear of the property. The applicant is also estimating approximately 112 cubic yards of subsidence at the site after compaction. Therefore, 3,050 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 204 to 305 deliveries. The site is located on an existing graded pad that will be modified to allow for split level pads for the basement and lower level floor area. A series of four 4 -foot high tiered retaining walls will be constructed to accommodate the additional pad area in the rear yard. Architectural Features, Colors, and Materials: The existing architectural style is California Ranch. The applicant is proposing to change the architectural style to Mediterranean. The applicant designed the project to have a variety of architectural elements to reflect the architectural style, including the following design features: ® Low pitched, hipped roof with clay roof tiles; ® Fagade details emphasizing horizontal lines, such as horizontal decorative band and stone veneer; ® Wrought iron architectural details, such as the doors and grilles over decorative windows, a Arched entrance with a tower structure; and a Natural colors used to highlight architectural details. The applicant is proposing to use a variety of colors and materials to create character and articulation. The fagade of the house will have stone veneer along the garage, entrance tower, and first level. Stucco will be located on the upper levels and on the eaves and exterior trims of the house. In addition, the entry door and window grilles will be wrought iron. The scale and proportions of the proposed addition are well balanced and appropriate for the site.

In the front yard, five -gallon shrubs such as manzanita, pittosporum, and wild lilac are proposed along the driveway. Three 36 -inch box London Plane and three 24 -inch box Coast Live Oak trees are used within the front yard to complement the architectural massing of the house. All plant types will be drought tolerant and non-invasive species. The project is required to comply with the City's Water Conservation Landscaping Ordinance, which is noted on the preliminary landscape plans and will be verified during building plan check. Development Review No PL 2012-529 Page 7 of 12 The subject property is located within the Los Angeles County Fire Department "Very High Fire Hazard Severity Zone." Therefore, the proposed landscaping must comply with the Fire Department's Fuel Modification Plan requirements. The landscape plans will be submitted for review and approval by the Fire Department during building plan check. 11 Sol 117- A MCUP is required if a change or expansion of a nonconforming structure is greater than 50 percent of the existing square footage of all structures on site and is not limited to the ground floor. Current development standards require a 30 -foot distance from the front property line to the structure. The existing residence has a nonconforming front setback of 19'-10" to the front property line. The City recognizes that homeowners should be allowed to make appropriate improvements to their properties, even if the exi�hegCimphaseestablished ftoudevelopment standards. Therefore, the MCUP process for such additions, subject to the findings set forth in the Development Code. MCUPs are normally subject to approval of the City's Hearing Officer (typically the Community Development Director). However, because this MCUP is being reviewed as part he of a DR application, both land use entitlements are subject to review and approval of t Planning commission. Staff believes that approving the MCUP as described above is appropriate and compatible with other residences in the neighborhood, based on the following facts and observations: • The existing dwelling was built in 1978, prior to the incorporation of the City of Diamond Bar; • The proposed addition will maintain and not further encroach into the existing nonconforming front setback of 191-10" to the front property line; 0 The proposed addition is located 30 feet from the front property line; and By maintaining the existing nonconforming front setback, the proposed project is consistent with other homes within the neighborhood. ION �41 11 Wt Tree Permits are required when the removal or protection of a protected tree is requested. A protected tree is any of the following: • Native oak, walnut, sycamore and willow trees with a diameter at breast height (DBH) of eight inches or greater; • Trees of significant historical or value as designated by the council; Page 8 of 12 Development Review No. PL 2012-529 0 Any tree required to be preserved or relocated as a condition of approval for a discretionary permit; • Any tree required to be planted as a condition of approval for a discretionary permit; and • A stand of trees, the nature of which makes each tree dependent upon the others for survival. The Development Code requires the preservation and maintenance of native oak and walnut trees with a DSII of eight inches or greater. When removal is allowed as a result of new development, replacement trees shall be planted at a 3:1 ratio in residential lots greater than 20,000 square feet. The applicant originally proposed to remove eight California Live Oak trees. Staff directed the applicant to revise the project to retain as many native protected trees, notably the existing 42 -inch California Live Oak tree. The applicant revised the project and is now proposing to remove five California Live Oak trees to accommodate the addition and the rear buildable pad (see site plan on the following page). As required, the landscape plan indicates that the replacement trees consist of fifteen 24 -inch box Coast Live Oaks. A total of 42 trees will be planted on the site. Figure 2: Perspective showing protected trees to be removed ------- -------- ---- ------- - — --- ------------- - .41 ( 7, 'A Figure 3: Site Plan W -IM Protected trees to be removed Property line Page 9 of 12 The applicant submitted an arboriculture report that indicates 25 protected trees, ranging from poor to good condition, exist on the property. The removal of five of the protected trees and replanting of 15 trees complies with the required minimum tree replacement ratio of 3:1. Therefore, it is not anticipated that the removal of the five protected trees and replacement of fifteen 24 -inch box trees will be detrimental to the overall contribution of natural vegetation of protected or non -protected tree species. To protect the remaining protected trees during construction, a condition of approval has been added to require chain link fencing to be installed to keep construction activity, equipment and materials at least five feet away from the driplines of the trees. A condition of approval requiring site verification prior to grading activity has been added to ensure this. LOMEt I II IF I ; WO al The proposed project was reviewed for compliance with the City's Hillside Management Design Guidelines and regulations. DBMC Section 22.22-120 (a)(1) establishes a height limit of 35 feet as measured from the finished grade to the highest point of the roofline. The project demonstrates that the proposed building will be 35 feet at the highest point. 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. The project site was designed with: * All proposed retaining walls associated with the building pad are at a maximum exposed height of four feet; ® Split pads are used to step up the natural slope; * Earth tone building materials and color schemes are used that blend in with the natural landscape; ® The project is terraced on four pad levels. From the street views, the building has an appearance of a three-story structure, but the rear of the building steps down to four levels. 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. ,lal OMNI, The proposed project complies with the goals and objectives as set forth in the adopted General Plan in terms of land use and density. The project is designed to be compatible with and enhance the character- of the existing homes in the neighborhood. The addition will not be intrusive to neighboring homes and will not block existing views since the home on the south side of the property is at a higher elevation and the property to the north is vacant. Development Review No, PL 2012-529 Page 10 of 12 The project incorporates the principles of the City's Residential Design Guidelines as follows: A gradual transition between the project and adjacent uses is achieved through appropriate setbacks, building height, landscaping, and window and door placement; 0 Elevations are treated with detailed architectural elements; Roof lines are representative of the design and scale of the structure through vertical and horizontal articulations such as gables and hips; Placement and relationship of windows, doors, and other window openings are carefully integrated with the building's overall design; Proper screening for ground and roof -mounted equipment is architecturally compatible with the dwelling in terms of materials, color, shape, and size and blends in with the proposed building design; 0 Large wall expanses without windows or doors are avoided; 0 Landscaping is used to emphasize and highlight focal points such as gardens, patios and walkways; and Landscaping is used to soften building lines and blend a structure with its environment, creating a transition between the hard vertical edges of the structure and the softer horizontal lines of the site. Adjacent Property to South Project Site Adjacent Property to North 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. Development Review No, PL 2012-529 Page 11 of 12 UTTIHII—MI-0 On March 12, 2014, public hearing notices were ,iailed to property owners within a 1,000 -foot radius of the project site. On March 14, 2014, the notice was published in the San Gabriel Valley Tribune and Inland Valley Daily Bulletin newspapers. A notice display board was posted at the site, and a copy of the notice was posted at the City's three designated community posting sites. No comments have been received as of the publication date of this report. PF4,15 �1-51 Fl! T This project has been reviewed for compliance with the California Environmental Quality Act (CEQA). Based on that assessment, the City has determined the project to be Categorically Exempt from the provisions of CEQA pursuant to the provisions of Article 19 Section 15301 (e) (additions to existing structures) of the CEQA Guidelines.

FINDINGS OF FACT Based on the findings and conclusions set forth herein and as prescribed under Diamond Bar Municipal Code (DBMC) Sections 22.48, 22.56, 22.38, this Planning Commission hereby finds as follows: Development Review Findings (DBMC Section 22.48.04 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): 2 DR/MCUPITP NO. PL2012-529 The design and layout of the proposed multi-level addition consisting of 4,573 square feet of floor area and 2,708 square feet of patio/balcony area to the existing single family residence is consistent with the City's General Plan, City Design Guidelines and development standards by meeting a// required setbacks except the front setback due to an existing nonconforming front setback of 19'-10". The addition is proposed toward the rear and south side of the property. The proposed addition does not further encroach into the front setback. The proposed addition and exterior remodel incorporates various details and architectural elements such as stone veneer, wrought iron window grilles and doors, low pitched hipped roof lines, arched entrance with tower structure, and appropriate massing and proportion to meet the intent of the City's Design Guidelines. 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 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 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 is a continuation of an existing use. 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 existing style of the home is California Ranch. The applicant is proposing to change the architectural style of the home to Mediterranean. The single- family home is designed to be compatible with the character of the eclectic neighborhoods in The Country Estates. The Mediterranean design includes features such as low pitched hipped roof, stone veneer, and integration with the natural landscape using split pads to step up the natural slope of the property. In addition, complementary wall materials are used to distinguish breaks in plane and add articulation to maintain and enhance the harmonious development in the neighborhood. 3 DR/MCLJP[TP NO. PL2012-529 4. The design of the proposed as developmtpvdeble environfor its occupants and visiting publc well as its neighbors through good aesthetic use of materials, texture, color, and will remain aesthetically appealing; The proposed design of the single-family home is Mediterranean.utilization of attrVariatactive ion in the building elements has been achieved through the architectural features, building materials, and landscaping. 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. 5. The proposed development will not be detrimental to public health, safets or y or welfare or materially injurious (e.g., negative effect on property value 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. rements. 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 strucQtures) drtscle 19 Section 15301 (e) (additions to existing of the CEQA guideline 'onditional Use Permit Findings (DBMG Section zz.znu-+u) The proposed use is allowed within the subject zoning district with the approval of a Minor Conditional Use Permit and complies with all other applicable provisions of this Development Code and the Municipal Code: The existing single-family dwelling is a permitted use in the RLM zone. A Minor Conditional Use Permit (MCUP) is requested to allow a second levewhere l additi30' ison to an existing nonconforming structure with a front setback of 19'-10", required. The substandard distance to the front property line renders the project nonconforming. The addition of a nonconforming structure requires approval of a Minor Conditional Use Permit because the addition is greater than 50 percent of the existing square -footage of all structures on site and is not limited to the ground floor. The proposed addition consisting of 4,537 square feet of floor 4 DRIMCUPITP NO. PL2012-529 area and 2 708 square feet of patio/balcony area to an existing two-level home complies with the development standards of the RR zone and will not further encroach into the nonconforming front setback. 2. The proposed use is consistent with the general plan and any applicable specific plan: The proposed addition to a single-family dwelling unit is consistent with the City's adopted General Plan. The site is not subject to the provisions of any specific plan. 3, The design, location, size and operating characteristics of the proposed use are compatible with the existing and future land uses in the vicinity: The existing single-family dwelling and the proposed addition consisting of 4,537 square feet of floor area and 2,708 square feet of patio/balcony area will not further encroach into the existing nonconforming front setback of 19'40" to the front property line. The proposed addition is set back 30 feet from the front property line. The proposed project is consistent with the surrounding neighborhood. The design of the existing single-family dwelling and the proposed addition are compatible with the character of the existing homes in the neighborhood, 4. The subject site is physically suitable for the type and density/intensity of use being proposed including access, provision of utilities, compatibility with adjoining land uses, and the absence of physical constraints, The subject site is physically suitable for the existing single-family residential dwelling and the proposed addition. The existing and proposed use of land is consistent with the surrounding land uses. The proposed addition of floor area is consistent with the development standards for the RR zone and will not further encroach into the existing nonconforming front setback. Because the proposed second floor addition is set back 30 feet from the front property line, the addition will not add bulk to the front of the house as seen from the street. 5. Granting the Minor Conditional Use Permit will not be detrimental to the public interest, health, safety, convenience or welfare, or materially injurious to persons, property or improvements in the vicinity and zoning district in which the property is located: and The granting of the Minor Conditional Use Permit will allow the addition of the existing single-family dwelling unit in a manner similar with existing dwelling units located in the surrounding neighborhood. The proposed expansion of the dwelling unit will not negatively impact the public interest, health, safety convenience or welfare. 6. The proposed project has been reviewed in compliance with the provisions of the California Environmental Quality Act (CEQA)-. 5 DR/MCUPITP NO, PL2012-529 The proposed project is categorically exempt from the provisiunderonArticls of the California Environmental Quality Act (CEQA) as set forth e 19 Section 15301 (e) (additions to existing structure) of the CEQA Guidelines.

Fete Volbeda From: Carlos Gonzales Ile: Bhavani Arborist Report I arrived on the property at 2577 Blaze Trail and observed a number of (Quercos acraifolius) California live oak trees at the rear of the dwelling. For the purpose of this report, I will focus on eight (8) of these trees. These trees range in size between 18"- 42" dbh (diameter at base height measured at 3 feet above ground level). The trees are numbered on the architectural plans as #1- #8. Trees numbered #4 through #7 are located closest to the dwelling and all have a dbh of 30" and are situated where the new deck will be constructed. The health of these trees are marginal as #5 and #7 show signs of heavy pruning as well as having a high skirt. They also show some signs of dead wood through the foliage, which may be signs of sun scald due to the thin canopy and high skirt. Tree #6 has been cut harder than the previous trees listed and appears to have more foliage discoloration. Tree # 4 had a co -dominate stem, which has broken off at ground level some time ago, and has never fully compartmentalized (properly sealed the wound). This opens the possibility for a fungal pathogen to enter into the existing tree, which has possibly already begun, upon examination of the broken stem. Trees #2 and #3 are in line with the proposed walkway and both show signs of wood decay on the main trunk. The plans show a new retaining wall which will cut into the roots of trees #6, #2, #1 and #8. This will compromise the trees' ability to remain properly anchored on the hillside, of which they are located. In addition, both trees numbered #1 and #2 exhibit signs of sun scald as well as wood decay. Tree #8 is the largest of the trees in which this report comprises, with a dbh of I ► i ► i�► i� c i ►�i �� ►� ► . i• 1z i Tree Care Specialists ne (909) 762-8664 onetreeman(o-)gmail. com 42" and a canopy of approximately 50'. This tree would potentially stand to suffer the greatest amount of root damage and be the first to topple in a severe windstorm, should it. remain in its location and the retaining wall is put in. The raising of the ground level would also compromise all of these trees ability to feed, but also their ability to have their roots obtain the proper amount of oxygen levels. This would also create a prime breeding ground for fungal pathogens to infect the trunks of the trees, possibly also into the other remaining Live oaks on the property. My recommendation is to remove these eight (8) aforementioned trees to alleviate any health problems to these as well as to the remaining (Quercos acrifolius) on the property. Trees number of trees removed shall be replaced by Quercos acrifolia, 15 gallon size, at a ratio of 3 trees to each tree removed. ( Smaller tree size is suggested due to the quantity of trees required.) The remaining Quercos acrifolia that are within 50 ft of the construction shall be protected during construction with a 5 ft height fence, preferable a minimum of 5 ft from canopy. Fence may be placed closer as circumstances require. Thank you, ('arlos C;onzafes Carlos Gonzales, ISA # WC 1330 (909)762-8664 -2- UTFIERN CALIFORNIA ARBOR Tree Care Specialists _.ie (909) 762-8664 onetreeman(a)gmail.com Addendum 3 21 2013 Per further discussion with the landscape architect, Tom Segura and the architect, Pete Volbeda, per the city's request we have revised the number of oak trees to be removed. Only 5 trees will be removed, per the revised attached plot plan. Two oak trees will have a retaining wall constructed to preserve the trees. Such retaining wall may be located under the drip line as shown on architectural plans. Arborist shall coordinate placement of wall footings to minimize damage to roots. Additionally, each tree shall be numbered, photographed, and identified with a permanent non- corrosive marker placed on the north side of the tree 4 '/z ft above base ( preserving its health and viability). Trees will be photographed, tagged and a revised report indicating such will be submitted to the city by April 2, 2012.
