Diamond Bar Boulevard, #B Diamond Bar, CA 91765 PROPERTY OWNER: Diamond Bar Town Center, LLC 6621 E. Pacific Coast Highway #270 Long Beach, CA 90803 APPLICANT: Shijie Chen 1110 Cleghorn Drive #B Diamond Bar, CA 91765 AP/Espinoza presented staff’s report and recommended Planning Commission approval of Conditional Use Permit No. PL2019-59, based on the Findings of Fact, and subject to the conditions of approval as listed within the Resolution. Chair/Barlas opened the public hearing. David Pai, Property Manager for the Diamond Bar Town Center, speaking on behalf of the property owner and tenant, said he appreciated the Commission’s hard work and stated that the chess academy provides a unique and valuable experience for the youth of this community. Mr. Chen, owner of the academy, is a chess champion and relatively young , and this is a great opportunity for the community to experience his ability. David said he would very much appreciate the Commission’s approval for this school. Chair/Barlas closed the public hearing. C/Mahlke moved, C/Rawlings seconded, to approve Conditional Use Permit No. PL2019-59, based on the Findings of Fact, and subject to the conditions of approval as listed within the draft resolution.

The subject property is zoned Rural Residential (RR) with an underlying General Plan land use designation of Rural Residential. No protected trees are being removed as part of this project. PROJECT ADDRESS: 22307 Broken Twig Road Diamond Bar, CA 91765 PROPERTY OWNER: Jacqueline Hsu 22888 Canyon View Road Diamond Bar, CA 91765 APPLICANT: Pete Volbeda 164 N. 2nd Avenue Upland, CA 91786 AP/Nakajima presented staff’s report and recommended Planning Commission approval of Development Review No. PL2017 -213, based on the Findings of Fact, and subject to the conditions of approval as listed within the resolution. C/Mahlke said that normally when the Commission sees projects in The Country Estates it is an indicator that it has proceeded through the architectural committee for approval. However, staff’s report indicates this project has not yet been approved by the committee and she asked if it was 4.1 Packet Pg. 9 ______________________________________________________________________ SEPTEMBER 10, 2019 PAGE 4 PLANNING COMMISSION ______________________________________________________________________ scheduled for review. AP/Nakajima explained that it is often submitted concurrently and perhaps the applicant can enlighten the Commission on the status. Chair/Barlas opened the public hearing. Pete Volbeda, Architect, spoke about the project and explained that he runs process plan concurrently through the City and the HOA so that he can apply any changes to both sets of plans at the same time. He expects to hear from the HOA within the next two weeks. Chair/Barlas closed the public hearing. VC/Farago moved, Chair/Barlas seconded, to approve Development Review No. PL2017-213, based on the findings of Fact, and subject to the conditions of approval as listed within the resolution. Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Mahlke, Rawlings, VC/Farago, Chair/Barlas NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: Mok Commissioner Mok returned to the dais. 7.3 Development Review No. PL2019-55 – Under the authority of DBMC Section 22.48, applicant Brian Huang and property owner Liu Chang Pei, requested Development Review approval to construct a 914 square foot, second story addition and a 116 square-foot patio, to an existing 1,272 square foot, single story residence on a 7,980 square foot lot. The subject property is zoned Low Density Residential (RL) with an underlying General Plan land use designation of Low Density Residential. PROJECT ADDRESS: 332 N. Platina Drive Diamond bar, CA 91765 PROPERTY OWNER: Liu Chang Pei 48 Sweet Fields Buena Park, CA 90620 4.1 Packet Pg. 10 ______________________________________________________________________ SEPTEMBER 10, 2019 PAGE 5 PLANNING COMMISSION ______________________________________________________________________ APPLICANT: Brian Huang 20472 Carrey Road Walnut, CA 91789 AP/Espinoza presented staff’s report and recommended Planning Commission approval of Development Review No. PL2019-55, based on the Findings of Fact, and subject to the conditions of approval as listed within the draft resolution. C/Rawlings stated that in the spirit of full disclosure, one of the neighbors met him out front to ask a couple of questions which started him thinking about whether there were any proposals to remove trees between the homes. AP/Espinoza stated that there was no proposal to remove any trees, only a proposal to re-landscape the front of the property. Chair/Barlas opened the public hearing. Aiko, 340 N. Platina and neighbor to the property under consideration asked about the estimated construction timeline because when she asked the owner she was told two to three months which she did not believe was achievable. She has a tree in her front yard that may conflict with the second story on the construction site depending on which plan the Commission approved and wanted to confirm that she would not be asked to cut any of her trees. In addition, she feels the second story will be very close to the large window in her master bedroom and asked if the applicant might be allowed to change from Plan A to Plan B. Clark Menace, Decorah Road, said he did not appreciate this project because he felt it would clutter the neighborhood and result in other similar projects and the streets would be blocked and it would ruin his view. He is opposed to this project and felt that if the applicant wanted a bigger house he should sell his one story house and find a bigger house to buy. Anthony Quijano lives in the house directly behind the proposed project and would not approve of this construction because it would block the view from his house and would depreciate the value of the property. Chair/Barlas closed the public hearing. C/Mahlke said that page 7 of 9 of staff’s report states that the property owner attempted to contact the neighbors to the north, south and east of the project to review the plans and obtain support. The neighbors to the north 4.1 Packet Pg. 11 ______________________________________________________________________ SEPTEMBER 10, 2019 PAGE 6 PLANNING COMMISSION ______________________________________________________________________ and east expressed their support for the project, but what was just stated by Mr. Quijano (property to the east) did not support the project. AP/Espinoza said she spoke with the property owner when she was writing the staff report and was told by the property owners that they went to the properties to speak to their neighbors, and according to the property owner, they received verbal support from the neighbors. However, the property owners are not present to confirm. C/Mahlke noted for the record that the neighbors in the audience were shaking their heads vehemently indicating that was not true. C/Rawlings said he was personally concerned about a couple of things and since the applicant is not present, he would hesitate to make a decision based on the information the Commission has at this point. He wondered about options for continuance of this matter to attempt to have all parties including the property owner present to respond. VC/Farago asked if staff could clarify the ordinance with respect to obstruction of views or a resident’s rights to a view. AP/Espinoza stated that the property located to the east (rear of the project site) is located approximately 18 feet above the finished grade of the existing home on the project site. The existing house is 13 feet tall and with the proposed edition, the house will be 23 feet tall. When the applicant originally presented this project, they proposed the addition to be located on the east side which would have impacted the neighbor’s complete view. So, staff directed the applicant to relocate the addition toward the north side to account for a “slot” view for the neighbor located to the east (rear of the project). While the design guidelines indicate that property owners can have slot views - they will not always be able to have panoramic views. C/Mahlke asked if it was true the Commission could not base a decision on whether or not it would preserve a neighbor’s view because there is no guarantee of that view as long as there is still some view available. CDD/Gubman stated that the view protection provisions in the Municipal Code and Design Guidelines acknowledge that views are an important attribute to residential properties in Diamond Bar, but it also expressly states that no resident is perpetually entitled to an unobstructed panoramic view and that there are going to be projects that will partially obstruct views. As AP/Espinoza indicated, staff worked with the applicant to redesign the structure to retain as much of the neighbor’s view as can be done given the relative positioning of the lots and structures built upon them. 4.1 Packet Pg. 12 ______________________________________________________________________ SEPTEMBER 10, 2019 PAGE 7 PLANNING COMMISSION ______________________________________________________________________ VC/Farrago said that it looks to him like there is a tree in front of the yellow box to the rear of the subject property that is approximately 23 feet high and is blocking the view of the neighbor to the east. Based on past projects, when there has been something of significance interfering with the view, the applicant has been asked to put a pole fram ing the addition so that Commissioners could visit the site to see what kind of impact the project might present. AP/Espinoza responded that story poles could be done. C/Rawlings stated that at this point he would probably abstain because he is not comfortable with his knowledge about how th is would impact the neighbors and having story poles would be very helpful. Chair/Barlas said it made sense to her as well and has been done for other projects. CDD/Gubman said that if the Commission needs that information to make an informed decision and to consider the concerns expressed this evening, it is within the Commission’s purview to continue the matter and direct the applicant to install story poles or actual field mockup to provide an opportunity for the Commission to see what the basic envelope of the building addition would be. C/Mok said that theoretically, the Commission could request the property owner and applicant to put up some story poles to allow the Commission to see how the outline of the addition would affect the view. Suppose the applicant and property owner refused to do so because they did not want to pay the cost and if that were to occur, how long would it delay the project? CDD/Gubman said it would delay the project at least until October 22, about six weeks from now. The Commission has a full agenda coming up and it will take time for the applicant/property owner to make arrangements to have the story poles installed. The public hearing can be continued to October 22nd or to a date uncertain and send out new meeting notices accordingly. Staff’s recommendation would be that if the Commission wished to continue the matter with the instruction to the applicant that the Commission would like to see the story poles, that this matter be continued to October 22nd and with continuance to that date, the item would not need to be re-advertised because the item will be placed on the October 22 nd agenda. Chair/Barlas reopened the public hearing. 4.1 Packet Pg. 13 ______________________________________________________________________ SEPTEMBER 10, 2019 PAGE 8 PLANNING COMMISSION ______________________________________________________________________ VC/Farrago moved, C/Mok seconded, to continue the public hearing for Development Review No. PL2019-55 to October 22, 2019, and request the applicant to install story poles. Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Mahlke, Mok, Rawlings, VC/Farago, Chair/Barlas NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: None AP/Espinoza explained to the Commission that the only window on the proposed 2nd story at 340 N. Platina facing the project is a bathroom window. C/Mahlke affirmed that the only plan under consideration by the Commission for this item is the addition on the north side which means there is a lesser view impact for the neighbors behind the project and less potential window conflict all around. AP/Espinoza stated that C/Mahlke was correct. 8. PLANNING COMMISSION COMMENTS/INFORMATIONAL ITEMS: None 9. STAFF COMMENTS/INFORMATIONAL ITEMS: 9.1 Project Status Report. CDD/Gubman reported that the Commission will now make up for having the entire month of August off beginning with the next meeting on September 24th during which there will be three public hearing items on the agenda, including two residential projects (a new single family residence in The Country and an addition in The Country) and a Conditional Use Permit for an existing office building on North Diamond Bar Boulevard a couple of doors south of Oak Tree Lanes and the auto center. The applicant is proposing to enlarge their parking lot by cutting into the back slope to accommodate more medical office tenants in the building. The September 24th meeting will be adjourned to September 25th for the first of two scheduled joint City Council/Planning Commission Study Sessions to introduce the General Plan document the City has been working on for the past three years. The hope is to get everyone introduced to the documents and provide as detailed an overview as possible and give the public an opportunity to weigh in early in the process. There will be a public review period that lasts for 45 days likely commencing at the end of this week and staff wants to provide these study sessions so that when the Public 4.1 Packet Pg. 14 ______________________________________________________________________ SEPTEMBER 10, 2019 PAGE 9 PLANNING COMMISSION ______________________________________________________________________ Hearings begin with the Planning Commission (November), Commissioners will be prepared to move forward with informed recommendations. In October, the Planning Commission will meet on the 22 nd and again on October 30th for a Special Meeting to consider the proposed hotel-anchored project at the former Brea Canyon Boat and Storage property. 10. SCHEDULE OF FUTURE EVENTS: As listed in the agenda.

The prope rty was developed in 1979 under Los Angeles County standards with a 4,120 square -foot, single-family residence and 827 square-foot garage on a 1.15 gross acre (49,891 gross square-foot) lot. There are no protected trees on the property. The proposed project is currently being reviewed by the Diamond Bar Country Estates Architectural Committee.

The property is a rectangular shaped lot and the property’s net buildable area (i.e., minus the private street easement) is 45,633 square feet (1.05 acres). The existing house is situated toward the front of the lot, approximately 21 feet from the edge of the private street easement line. An existing three-car garage faces the front of the property. The applicant is proposing to expand the garage by adding two tandem parking spaces and a workshop. There is an existing driveway that leads to the existing garage. The proposed project also includes a circular driveway at the front of the property. The proposed project includes rear yard improvements, including a swimming pool, spa, covered patio and partial basketball court. Grading Plan The existing house is located on a steep descending slope that begins at the private street easement. There is an existing 12-foot high retaining wall located below the garage, that supports the existing building pad. The applicant is proposing to cut 17 cubic yards o f soil toward the east side of the property and fill 6,018 cubic yards of soil toward the rear of the property to expand the existing building pad. The proposed earthwork requires 6,000 cubic yards of fill 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 400 to 600 total truck trips. 7.1 Packet Pg. 19 Development Review and Minor Conditional Use Permit No. PL2018-157 Page 5 of 11 The applicant is proposing five 4-foot high retaining walls located at the rear of the property to support a fill above the natural grade to create the building pads for the rear yard improvements. All exposed portions of retaining walls will be stuccoed to match the house. Architecture The applicant is proposing to change the architectural style to a contemporary Mediterranean design, including features such as a low-pitched hipped roof style with concrete s-tiles, decorative brackets that support wide overhanging eaves, decorative arched windows on the first floor and rectangular windows on the second floor, wrought iron railings throughout the house, and balustrade railings at the rear of the house. The entryway includes an arch above the transom window above the entry door. 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.

Additionally, various 5-gallon and 1-gallon shrubs that have a variety of color, texture, and form are proposed throughout the street side and rear yard slopes. Overall, landscaping consists of drought tolerant and non -invasive species to minimize irrigation and reduce the area of turf. The project is requi red to comply with the City’s Water Efficient Landscaping Ordinance, and compliance will be verified during building plan check and final inspections. The subject property is located within the Los Angeles County Fire Department “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. ANALYSIS Review Authority The proposed project requires two separate, but interrelated, land use approvals: Development Review (DR) and a Minor Conditional Use Permit (MCUP). The analysis that follows provides the basis for staff’s recommendation to approve the DR and MCUP applications. Development Review (DBMC Section 22.48) Additions which are equal to or greater than 50 percent of the existing habitable floor area of all existing structures on site, or substantially change the appearance of an existing residence require Planning Commission approval of a DR application. Development Review approval is required to ensure compliance with the City’s General Plan policies 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 th e 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: 7.1 Packet Pg. 22 Development Review and Minor Conditional Use Permit No. PL2018-157 Page 8 of 11 Development Feature Residential Development Standards Existing Proposed Meets Requirements Front Setback 30 feet 21’-2” 21’-2” No* Side Setbacks 10 feet on one side and 15 feet on the other side 22’-9”– north side 22’-7”– south side 22’-9”– north side 16 feet – south side Yes Distance to Structures on Adjoining Lots 25 feet 37’-1”– north side 47 feet – south side 37’-1”– north side 40’-10”– south side Yes Rear Setback 25 feet 0 feet 59’-5” Yes Lot Coverage Maximum of 30% 6.7% 15% Yes Building Height Limit 35 feet 23 feet 35 feet Yes Parking 2-car garage 3-car garage 5-car garage Yes Minor Conditional Use Permit An 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, or if the addition is not limited to the ground floor. Current development standards require a minimum front setback of 30 feet from the house to the private street easement. The existi ng residence has a nonconforming front setback of 21 feet, 2 inches to the private street easement. The proposed addition is located at the front, rear and side of the house and does not further encroach into the front setback. The City recognizes that homeowners should be allowed to make appropriate improvements to their properties, and reasonable accommodations should be made to permit additions and alterations to nonconforming structures. The MCUP process is the tool used to consider such accommodations, 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 of a DR application, both land use entitlements are subject to review and approval of the 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: *Minor Conditional Use Permit is requested to allow the continuation of a nonconforming structure because the addition is greater than 50 percent of the existing home. See MCUP discussion below. 7.1 Packet Pg. 23 Development Review and Minor Conditional Use Permit No. PL2018-157 Page 9 of 11 • The existing dwelling was built in 1979, prior to the incorporation of the City of Diamond Bar; • The proposed addition complies with the required rear and side setbacks and distances to the adjacent properties, and does not further encroach into the existing nonconforming 21-foot, 2-inch front setback; and • Neighboring properties have nonconforming front setbacks, so the proposed project will remain consistent with other homes within the neighborhood. Compliance with Hillside Management Ordinance (DBMC Section 22.22) The proposed project was reviewed for compliance with the City’s Hillside Management Design Guidelines and regulations. The project complies with all of the regulations and guidelines to ensure that development will complement t he character and topography of hillside areas set forth in the Development Code, and incorporates the following features: • All proposed retaining walls associated with the building pads are at a maximum exposed height of four feet; • The project is terraced on split-level pads. From the street view, the building is a two-story structure, but the rear of the building is four levels (including the basement level); and • Earth-tone building materials and color schemes are used that blend in with the natural landscape. 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. Compatibility with Neighborhood The project is located between a two-story home to the north and a three-story home to the south. The proposed addition will not be intrusive to neighboring homes since the proposed addition will not block existing views from adjacent properties. The adjacent homes to the north and south have views to the west and the house across the street to the east has views to the east. Although the applicant is adding 4,367 square feet of living space and 349 square -foot garage addition, the house will be similar in mass and scale compare d to other existing homes on similar lots in The Country. The architecture in The Country is eclectic and includes a variety of architectural designs. The scale and proportions of the addition are well balanced and appropriate for the site. In sum, the proposed project fits the character of the neighborhood on which it is proposed. 7.1 Packet Pg. 24 Development Review and Minor Conditional Use Permit No. PL2018-157 Page 10 of 11 • A gradual transition between the addition and existing residence is achieved through appropriate setbacks, building height and window and door placement; • Placement and relationship of windows, doors, and other window openings are carefully integrated with the building’s overall design; • Elevations are treated with detailed architectural elements; • 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; and • The exterior finish materials and colors blend with the natural environment.

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 Environm ental Quality Act (CEQA) pursuant to the provisions of Article 19, Section 15301 (e) (additions to existing structures) 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, 22.56, and 22.68, 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 addition consisting of 4,367 square feet of living area, 349 square feet of garage area, 4,446 square feet of patio/deck area, and 817 square feet of storage/mechanical room area to the front, side and rear of an existing single-family residence is consistent with the City’s General Plan, City Design Guidelines and Development Code standards. The mass and scale of the addition are proportionate to the existing house and surrounding properties. The proposed façade remodel incorporates contemporary Mediterranean architectural elements such as a low-pitched hipped roof with concrete s-tiles, decorative brackets that support wide overhanging eaves, decorative arched windows on the first floor and rectangular windows on the second floor, wrought iron railings throughout the house, and balustrade railings at the rear of the house, and appropriate massing and proportion to meet the intent of the City’s Design Guidelines. 7.1.a Packet Pg. 28 3 PC Resolution No. 2019-XX 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 development s, 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 movem ents, 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 project is located between a two-story home to the north and a three-level home to the south. The proposed addition will not be intrusive to neighboring homes since the proposed addition will not block existing views from adjacent properties because the adjacent homes to the north and south have views to the west and the house across the street to the east has views to the east. The house will be similar in mass and scale compared to other existing homes on similar lots in The Country. The proposed design will be modified to a contemporary Mediterranean style of architecture. The architecture in The Country is eclectic, and includes a variety of architectural designs. The scale and proportions of the addition are well balanced and appropriate for the site. 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 applicant is proposing to change the architectural style to a contemporary Mediterranean design, including features such as a low -pitched hipped roof with concrete s-tiles, decorative arched windows on the first floor and rectangular windows on the second floor, wrought iron railings throughout the home, and balustrade railings at the rear of the home. The entryway includes an arch above the transom windows and door. 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 addition are well balanced and appropriate for the site. 7.1.a Packet Pg. 29 4 PC Resolution No. 2019-XX 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. 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 (CEQA). The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) as set forth under Article 19 Section 15301 (e) (additions to existing structures) of the CEQA guidelines. Minor Conditional Use Permit Findings (DBMC Section 22.56.040) 1. 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 provision s of this Development Code and the Municipal Code. The existing single-family dwelling is a permitted use in the RR zone. A Minor Conditional Use Permit (MCUP) is requested to allow an addition over 50 percent of the existing square-footage to a nonconforming structure with a preexisting nonconforming front setback of 21 feet, 2 inches (where 30 feet is required). The preexisting substandard front setback 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 home. The proposed addition consisting of 4,367 square feet of living area, 349 square-foot garage addition, 4,446 square feet of deck/patio area, and 817 square feet of storage/mechanical room area 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 a nd 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 4,367 square feet of living area, 349 square-foot garage addition, 4,446 square feet of deck/patio area, and 817 square feet of storage/mechanical room area will not 7.1.a Packet Pg. 30 5 PC Resolution No. 2019-XX further encroach into the existing nonconforming 21-foot, 2-inch front setback. The proposed addition is located at the front, side, and rear of the house. The façade remodel of the existing single-family dwelling and the proposed addition are compatible with the character of the existing homes in the n eighborhood because the architecture in The Country is eclectic and includes a variety of architectural designs. Therefore, the addition will not negatively impact the look and character of 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 is consistent with the development standards for the RR zone and will not further encroach into the existing nonconforming front setback. 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. 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). The proposed project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) as set forth under Article 19 Section 15301 (e) (additions to existing structure) of the CEQA Guidelines. Non-Conforming Structures Findings (DBMC Section 22.68.030) The addition, enlargement, extension, reconstruction, relocation or structural alteration of the nonconforming structure would not result in the structure becoming: 1. Incompatible with other structures in the neighborhood. The proposed four-level addition of floor area is consistent with the development standards for the RR zone. The proposed addition consisting 4,367 square feet of living area, 349 square-foot garage addition, 4,446 square feet of deck/patio area, and 817 square feet of storage/mechanical room area will comply with current development standards and not further encroach into the existing nonconforming front setback. The proposed project is located at the front, side, and rear of the existing home. The existing and proposed land use is consistent with the 7.1.a Packet Pg. 31 6 PC Resolution No. 2019-XX surrounding land uses and structures in the neighborhood. Additionally, the neighboring properties also have nonconforming front setbacks, so the proposed project will remain consistent with other homes within the neighborhood. 2. Inconsistent with the general plan or 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. A restriction to the eventual/future compliance with the applicable regulations of this Development Code. The existing and proposed land use is consistent with the surrounding land uses with similar front setbacks. The proposed addition of floor area is consistent with the development standards for the RR zone and will not encroach into the existing nonconforming front setback. 4. Detrimental to the health, safety and general welfare of persons re siding in the neighborhood. 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/Engineering 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. 5. Detrimental and/or injurious to property and improvements in the neighborhood. The addition to the existing single-family dwelling unit will be constructed in a manner similar with existing dwelling units located in the surrounding community and will not be detrimental and/or injurious to property and improvements in the neighborhood. 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. Prior to building permit issuance, the required landscape plan shall be designed to meet the requirements of the Los Angeles County Fire Department’s Fuel Modification Plan Guidelines in terms of plant selection, placement and maintenance. The final landscape and fuel modification plans shall be submitted to the Los Angeles Fire Department for review and approval. 7.1.a Packet Pg. 32 7 PC Resolution No. 2019-XX 3. Prior to building permit issuance, a Certification of Design, together with landscape and irrigation plans prepared by a licensed landscape architect, shall be submitted to the Planning Division for review and approval by the City’s Consulting Landscape Architect. Landscape and irrigation plans shall comply with the updated Water Efficient Landscaping Ordinance. 2. Standard Conditions.

(909) 839-7030 ~ FAX (909) 861-3117 7.2 Packet Pg. 67 Development Review No. PL2016-195 Page 2 of 11 BACKGROUND: The project site is located in the Diamond Bar Country Estates (The Country), on the south side of Shotgun Lane, east of Derringer Lane. The property was developed in 1976 under Los Angeles County standards with a 3,802 square-foot, single-family residence and garage on a 1.84 gross acre (80,146 gross square-foot) lot. There are 57 trees on the property, none of which are classified as protected trees. The proposed project is currently being reviewed by the Diamond Bar Country Estates Architectural Committee. The property is legally described as Lot 16 of Tract No. 24046, and the Assessor’s Parcel Number (APN) is 8713-002-028. Site and Surrounding General Plan, Zoning and Land Uses The image below highlights the subject property: N Project Location 7.2 Packet Pg. 68 Development Review No. PL2016-195 Page 3 of 11 Project Site Adjacent Property to East Adjacent Property to West 7.2 Packet Pg. 69 Development Review No. PL2016-195 Page 4 of 11 The following table summarizes the land uses and zoning of the subject property and its surroundings: General Plan Designation Zoning District Land Use Site Rural Residential RR Single-Family Residential North Park & PA-2/SP RL Park South Rural Residential RR Single-Family Residential East Rural Residential RR Single-Family Residential West Rural Residential RR Single-Family Residential Project Description Site Plan As stated, the property’s gross lot area is 80,146 square feet (1.84 gross acres), which includes a 32-foot wide private street easement for Shotgun Lane along its frontage. The subject property is rectangular in shape, with a net buildable area (i.e., minus the private street) of 70,134 square feet (1.61 acres). There is an existing driveway that is shared with the adjacent neighbor to the east. The property is a hillside property and is located on ascending slope that starts from the private street easement to the center of the property. There is also a descending slope located at the rear of the property . The proposed house is situated toward the center of the lot, approximately 125 feet from the edge of the private street easement line. The entrance to the proposed house faces Derringer Lane. The applicant is proposing a driveway with a switchback design to reduce the steepness of the slope and provide adequate access for Los Angeles County Fire Department emergency vehicles. A portion of the existing shared driveway will remain in order to provide access to the adjacent property to the east. A proposed seven-car garage is located below grade in the basement level. The applicant is proposing rear yard improvements consisting of a pool, spa, gazebo, putting green, tennis court, fire pit, and outdoor kitchen with a barbeque area. Grading Plan The applicant is proposing to cut 8,200 cubic yards of soil toward the west side and rear of the property to construct the basement level and fill 8,200 cubic yards of soil primarily toward the front and rear of the property to expand the existing building pad. Therefore, the site will be balanced and no import or export of soil will be required. 7.2 Packet Pg. 70 Development Review No. PL2016-195 Page 5 of 11 The applicant is proposing two four--foot high retaining walls toward the front of the property to support a fill above the natural grade for the proposed switchback driveway. The applicant is proposing two pads at the rear of the property. The upper buildable pad—containing the majority of the rear yard improvements—is created by three-tiered retaining walls with a maximum height of four feet that support a fill above the natural grade. The lower pad that contains the tennis court will be supported by two crib walls with a maximum height of four feet that support a fill above the natural grade. All exposed portions of retaining walls will be stuccoed to match the house or clad with decorative block. Architecture The design of the proposed home is eclectic with Greek revival elements, including Doric columns, a full-height entry with a low-pitched pediment for a porte-cochere, a low-pitched hipped roof with flat roof tiles, and stucco foam window trim moldings surrounding tall windows. The colors and materials include earth-toned smooth stucco. The proposed three-level house’s floor plan is comprised of the following components: • Basement level: seven-car garage, storage rooms, server room, and powder room; • First floor level: common areas (entry area, living room, wet bar, great room, dining room, kitchen, prep kitchen, two pantries, wine cellar, breakfast nook, family room, and game room); three bedrooms with bathrooms and walk-in closets; bedroom suite with a sitting room, walk-in closet, and bathroom; study; library; exercise room with a bathroom and sauna; two powder rooms; laundry room; and storage room; Proposed Front Elevation 7.2 Packet Pg. 71 Development Review No. PL2016-195 Page 6 of 11 • Second level: master suite with a sitting area, office, linen closet, master bathroom, and walk-in closet; four bedrooms with bathrooms and walk-in closets; loft area; laundry room; • Elevator to access all three levels; and • 3,347 square feet of balcony, patio, and porch areas throughout the residence. The floor area distribution is summarized below: The height of the building is 35 feet, measured from the finished grade to the highest point of the roofline. Landscape Plan The applicant is proposing a variety of trees to be planted throughout the property, including: 31 Italian cypress trees along the length of the driveway, consisting of a mix of 24- and 36-inch box container sizes; two 36-inch box olive trees at the driveway entrance; 16 (sixteen) 24-inch box Italian cypress trees along the west side property line; and seven 15-gallon fruit trees located on the slope at the rear of the property. Additionally, various 5-gallon and 1-gallon shrubs that have a variety of color, texture, and form are proposed throughout the street side and rear yard slopes. Overall, landscaping consists of drought tolerant and non -invasive species to minimize irrigation and reduce the area of turf. The project is required to comply with the City’s Water Efficient Landscaping Ordinance, and compliance will be verified during building plan check and final inspections. There are currently several 30- to 60-foot tall Canary Island pine trees located on the slope at the front of the property. Staff requested that the applicant redesign the switchback driveway so the canary pine trees could remain on the property.

The revised site plan was not approved because it did not comply with the fire code regulations for access due to the steepness of the driveway. Therefore, the applicant resubmitted the project with the original switchback driveway to comply with the LA County Fire Department fire code regulations for access. As previously stated, the applicant is proposing to remove seven Canary Island Pine trees located on the existing ascending slope at the front of the property. The applicant is proposing to install a total of 31 Italian cypress trees at the front of the property, along the length of the switchback driveway to replace the Canary Island pine trees. There are also seven existing bottle trees located along the edge of the private street easement that will remain at the front of the property, in front of the white vinyl fencing. Aerial View of Project Site from the North 7.2 Packet Pg. 73 Development Review No. PL2016-195 Page 8 of 11 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. ANALYSIS: Review Authority The proposed project requires a land use review and approval through the Development Review process. The analysis that follows provides the basis for staff’s recommendation to approve the Development Review application. Development Review (DBMC Chapter 22.48) 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 Portion of the Project Site from Shotgun Lane 7.2 Packet Pg. 74 Development Review No. PL2016-195 Page 9 of 11 functional and aesthetic standards to complement and add to the economic, physical, and social character” of Diamond Bar.

The p roject 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, and incorporates the following features: • All proposed retaining walls associated with the building pads are at a maximum exposed height of four feet; • From the street view, the building is a two -story structure because the basement level is entirely below grade level; and • Earth tone building materials and color schemes are used that blend in with the natural landscape. 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. 7.2 Packet Pg. 75 Development Review No. PL2016-195 Page 10 of 11 Compatibility with Neighborhood The proposed project is located between two-story homes on both sides. The new house will not be intrusive to neighboring homes since the proposed house will not block existing views from adjacent properties. The adjacent house to the eas t is located on a lower grade and has views to the north and south. The adjacent house to the west is located on a higher grade and has views to the north, south and west. The proposed house is comparable in mass and scale to existing homes on similar l ots in The Country. The architecture in The Country is eclectic, and includes a variety of architectural designs. In addition, the house is located 40 feet above the street grade and is located approximately 125 feet from the private street easement. The scale and proportions of the proposed home are well balanced and appropriate for the site. In sum, the proposed project fits the character of the neighborhood on which it is proposed. • The new single-family residence will conform to all development standards, including building height and setbacks, which is consistent with other homes in The Country; • A gradual transition between the project and adjacent uses is achieved through appropriate setbacks, building height, landscaping, and window and door placement; • The proposed new single-family residence is appropriate in mass and scale to the site; • 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; • The exterior finish materials and colors blend with the natural environment; and • Effective landscape design should serve the dual purpose of intrinsically enhancing a project setting, as well as integrating the landscaping into the overall architectural design. Staff finds the proposed plant palette to be diverse, and the plant selections are compatible with Southern California native landscapes.

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 7.2.a Packet Pg. 78 2 PC Resolution No. PL2019-XX 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) Section 22.48, 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 single -family residence consisting of 15,011 square-foot single-family residence with 2,915 square feet of garage area, 3,599 square feet of patio/gazebo area, and 3,491 square feet of storage areas is consistent with the City’s General Plan, Design Guidelines and development standards. A gradual transition between the project and adjacent uses is achieved through appropriate setbacks, building height, landscaping, and window and door placement. The proposed new single-family residence incorporates architectural elements such as a low-pitched hipped roof with concrete flat tiles, a porte cochere with a gable pediment, elongated windows throughout the house, stucco exterior finishes; 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 development s, 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 7.2.a Packet Pg. 79 3 PC Resolution No. PL2019-XX 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 proposed house is comparable in mass and scale to existing homes on similar lots in The Country. The architecture in The Country is eclectic, and includes a variety of architectural designs. The scale and proportions of the proposed home are well balanced and appropriate for the site. In sum, the proposed project fits the character of the neighborhood on which it is proposed. 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 eclectic with Greek revival elements such as Doric columns, low pitched hipped roof with flat concrete roof tiles, a port-cochere with a low-pitched pediment, and tall windows. 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 co mplement 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 (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 docum ents presented to the Planning Commission at the public hearing. 2.

Diamond Bar Boulevard Diamond Bar, CA 91765 (APN: 8706-002-055) GENERAL PLAN DESIGNATION: Commercial Office (CO) ZONING DISTRICT: Professional Office (OP) PROPERTY OWNER: Johnney Y. Zhang Zhang Group 750 N. Diamond Bar Blvd., Suite 188 Diamond Bar, CA 91765 APPLICANT: Howard Zelefsky 9735 La Capilla Ave Fountain Valley, CA 92708 SUMMARY: The applicant is requesting approval of a Conditional Use Permit (CUP) to increase the percentage of floor area allocated to medical office uses at an existing 35,687 square- foot professional office building. Because medical uses require a higher parking-per- square-foot parking ratio than general office uses, the applicant is concurrently proposing to create 19 new on-site parking spaces by cutting into slope at the rear of the subject property, and supporting the cut with three tiers of six-foot tall retaining walls. On September 18, 2019, staff received written comments from the neighboring commercial property owner to the north, expressing opposition to the request. Among other things, the neighboring property owner contends that the subject property currently lacks sufficient on-site parking to meet demand, resulting in patrons parking CITY OF DIAMOND BAR ~ 21810 COPLEY DRIVE ~ DIAMOND BAR, CA 91765 ~ TEL.

RECOMMENDATION: In light of the new information received, staff recommends that the Planning Commission open the public hearing, receive public comments, and continue the matter to October 30, 2019. The purpose of the continuance would be to allow the applicant and staff to investigate the issues raised by the neighboring property owner. BACKGROUND: The subject property is located at the east side of Diamond Bar Boulevard, between Highland Valley Road and Sunset Crossing Road. The office building that currently occupies the site was developed in 1981, prior to the City’s incorporation. The building has 35,687 square feet of leasable floor area . The current tenant mix includes general office, medical office, medical lab and bank uses. There are currently 100 parking spaces on site. North Diamond Bar Boulevard is currently striped with a Class 2 bike lane, and on-street parking is currently prohibited. In June 2017, staff approved a Plot Plan application to renovate the exterior of the building and relandscape the site (Planning Case No. PL2017-52). The property is legally described as Lots 10 and 11 of Tract No. 34803. The Assessor’s Parcel Number (APN) is 8706-002-055. Site and Surrounding General Plan, Zoning and Land Uses The following table describes the surrounding land uses and zoning located adjacent to the subject property: General Plan Designation Zoning District Land Use Site Commercial Office OP Professional Office Building North Commercial Office OP Multi-Tenant Automobile Service Center South Commercial Office OP Professional Office Building East Low Density Residential RL Single-Family Homes West N/A N/A SR 57 Freeway 7.3 Packet Pg. 114 Conditional Use Permit Planning Case No. PL2017-139 Page 3 of 8 Project Site Site Aerial 7.3 Packet Pg. 115 Conditional Use Permit Planning Case No. PL2017-139 Page 4 of 8 PROJECT DESCRIPTION AND ANALYSIS Intensification of Use The applicant is requesting approval to increase medical office uses from 11,634 square feet to 16,906 square feet. In addition, the applicant intends to lease 1,190 square feet to a retail pharmacy tenant. To facilitate these uses, general office would concurrently be reduced from 19,243 square feet to 12,781 square feet. The table below summarizes the proposed redistribution of floor area and associated parking requirements. Use Parking Requirement (DBMC §22.30.040) Existing Proposed sq. ft. Parking required Sq. ft.

The table also illustrates that the proposed addition of 19 Adjacent Property to the South Adjacent Property to the North 7.3 Packet Pg. 116 Conditional Use Permit Planning Case No. PL2017-139 Page 5 of 8 Proposed Site Plan parking spaces would bring the site into compliance with th e City’s parking regulations by both erasing the current deficit and by providing ten additional spaces to meet the parking requirement generated by intensification of medical uses and the addition of a pharmacy. Parking Lot Expansion As shown below, the applicant proposes to cut approximately 25 feet horizontally into the slope at the rear of the property, and supporting the cut with three tiers of six-foot tall retaining walls to create the additional surface area to accommodate the parking lot expansion. A decorative finish, such as split-faced block or painted stucco, is proposed on the exposed sides of these retaining walls. The estimated volume of soil export associated with the proposed retaining wall construction is 2,454 cubic yards. Also shown below are two new storage sheds proposed at the opposite ends of the expanded parking. Landscaping Pursuant to DBMC Section 22.24.040 Table 3-6, properties zoned Office Professional (OP) shall provide for a minimum of 20 percent of the site area for landscaping. The Code also requires office uses to provide landscaping within the parking area at a ratio of five percent of the gross area of the parking lot, as well as one tree for every eight parking spaces [DBMC Section 22.30.070 (8)(g)(1)]. The proposed areas allocated for landscaping (including the rear slope) is 27,314 square feet, which complies with both N B C A 7.3 Packet Pg. 117 Conditional Use Permit Planning Case No. PL2017-139 Page 6 of 8 requirements noted above. Three 24-inch box blue palo verde trees are proposed in planter areas for every eight parking spaces within the new parking area and 1-gallon creeping myoporum shrubs are proposed between the retaining walls. The project is required to comply with the City’s Water Efficient Landscaping Ordinance, and compliance will be verified during building plan check and final inspections. As part of the 2017 façade remodel and landscaping improvements , six California Sycamores were planted on the slope at the rear of the property. The closest tree is approximately eight to ten feet from the highest proposed retaining wall. The applicant intends to retain those trees in place. Conditional Use Permits (DBMC Section 22.58) A CUP is required for uses whose effect on the surrounding area cannot be determined before being analyzed for suitability at a particular location. When reviewing a CUP, consideration is given to the location, design, configuration, operational characteristics and potential impacts to determine whether or not the proposed use will pose a detriment to the public health, safety and welfare. If it can be found that the proposed use is likely to be compatible with its surroundings, the Commission may approve the proposed use subject to conditions stipulating the manner in which the use must be conducted. If the Commission finds that the proposed use is likely to be detrimental to the general peace, health and general welfare, then it must deny the request. When a CUP is approved, it runs with the land and all conditions placed on the CUP are binding on all successors in interest. In other words, if the owner was to sell the building, the new owner could place approved uses in the same spaces allocated and operate the same type of use. The new tenant(s) would be required to comply with the same conditions as the previous tenant and would not be permitted to expand the use without full review and approval by the Planning Commission. Neighborhood Compatibility The building has various uses, including general office, medical office, a medical lab, bank, and storage. The adjacent property to the north is a legal nonconforming auto repair shop and the adjacent property to the south is a lso a professional office building. Given the similar nature of the proposed uses with the uses already existing within the building, it is reasonable to conclude that the medical office and pharmacy will be compatible within the building and with the neighborhood. NOTICE OF PUBLIC HEARING: On September 12, 2019, public hearing notices were mailed to property owners within a 500-foot radius of the project site. On September 13, the notice was published in the Inland Valley Daily Tribune and San Gabriel Valley Tribune newspapers; the project site 7.3 Packet Pg. 118 Conditional Use Permit Planning Case No. PL2017-139 Page 7 of 8 Image of Parking Lots of Subject Site and Adjacent Property to the North was posted with a notice display board; and a copy of the public notice was posted at the City’s four designated community posting sites PUBLIC COMMENTS RECEIVED: Staff received a letter from the adjacent property owner to the north (Attachment B). Among several issues raised, information was provided regarding the current parking situation. Parking lots of the subject site and adjacent properties have signs informing visitors that parking is for customers only and violators will be towed. According to the letter, customers for the office building are parking on adjacent properties due to the parking shortage and is causing vehicles to be towed. While there is a verified shortage of nine parking spaces on the subject property, and the applicant proposes to add 19 new spaces to erase the shortage and accommodate a retail pharmacy and a higher percentage of medical office square footage, staff believes that it would be prudent to continue the public hearing to October 30, 2019 so that the issues raised by the neighboring property owner may be properly investigated. ENVIRONMENTAL ASSESSMENT: The 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 Article 19 under Section 15301 (Existing Facilities) and Section 15311 (Accessory Structures) of the CEQA Guidelines. No further environmental review is required. PREPARED BY: 7.3 Packet Pg. 119 Conditional Use Permit Planning Case No. PL2017-139 Page 8 of 8 REVIEWED BY: Attachments: A.

Stonewood owns the auto center just north of the subject property located at 780-796 North Diamond Bar, Diamond Bar, CA. Stonewood reviewed the applicant’s file, parking study and plans in the City of Diamond Bar Offices on September 18, 2019. Stonewood objects to the issuance of a C.U.P. for increased medical office use and the expansion of the parking area into the rear slope based on the following: • The applicant and the 750 N. Diamond Bar Property are part of private reciprocal easement agreement dated October 31, 1985 (attached). Stonewood contends that the proposed modifications to the parking or the site require the prior written consent of all the property owners subject to this agreement since said improvement will affect the adjacent building’s foundation, drainage and potentially utilities which is addressed in Paragraph 2c of the agreement. Applicant has not obtained consent from any of the adjacent owners. Any City approval should require this private party consent prior to issuing a C.U.P. or building permit for extensive slope work to add 19 new parking stalls. • Applicant’s file lacks any plans by a licensed Civil Engineer, a professional soils report, a structural review, safety review or any aesthetic elevations which are subject to public review and approval. Public Works intends to have these reports produced and reviewed after the C.U.P. approval and prior the issuance of a building permit. This process would not include any public review or sign off by adjacent owners. The contemplated plan by the Applicant would expose the adjacent building’s foundation at 780 N. Diamond Bar which shares a zero-lot line and may cause underlying structural damage and potentially change the drainage flow below and around the building. Please see photo attached of area that will be affected. Applicant’s plans are silent to any of these issues with the adjacent building and a full structural review including construction methods should be conducted and studied prior to any approvals being granted. 7.3.b Packet Pg. 125 2530 Redhill Avenue, Ste. 225 Santa Ana, CA 92660 P) 949-250-9100 • Modification to the common slope – The slope in which applicant is looking to modify has issues with previous slides, excessive hydrology flow onto the properties below and offers an aesthetic view corridor to properties adjacent. The new retaining wall appears to be listed on plans at 6’, though it fails to clearly describe that it is in fact a 3 retaining wall system of each section being 6’ for a total of approximately 18’ from top to bottom. This is a massive wall which should require structural review, an elevation to understand construction finishes and a safety review. Children, homeless, contractors and others find their way on to the slope from time to time should not be subject to an 18’ fall from the top of proposed wall to the ground without a safety rail. There is also a common easement for a drainage swell and catch basin which will need additional study to ensure proper water flow across the applicant’s site. Modifications to this slope area seems unwise and again has not been approved by the adjacent property owners. • Parking – The parking for the 750 building is already at full capacity with its current uses and overflows onto our adjacent property without our consent. We have invoked our rights to restrict parking from the 750 building, added “No Parking” signs and now legally tow violators from time to time. We understand that applicants parking plan may meet current code with all the parking located on site, if their plan is approved. From a practical standpoint the site is under parked with tight drive aisles, intensifying the parking uses does not seem prudent and frankly short sighted by the applicant to subject its unknowing visitors to tow charges and undue stress when they can’t find spot on site and quickly park on the adjacent properties to make a medical appointment. It always seems unfair when a car has to be removed. The parking study dated 8-8-18 by Linscott Law & Greenspan Engineering eludes to open stalls in adjacent properties, all stalls on the adjacent properties are under “Exclusive Use” and no longer available to the 750 Building’s tenants or visitors. Our Official Notice to the applicant is enclosed for your review, you may wish to request copies from other surrounding owners as well. This property was originally approved under the County before being annexed into the City of Diamond Bar. The original approval restricted the amount medical in this building and we encourage the percentage to remain unchanged and the C.U.P. in question to be denied or at least suspended for vote until a full professional design package can be reviewed by the public. Please include this objection letter to public file and we reserve the right to attend the meeting on September 24, 2019 to express our objections in person and expand on our points of contention. Stonewood reserves all their legal right and remedies. Sincerely, Stonewood Properties, Inc. As agent for owner. Jim Wood James R.
