A. Recitals. 1. Aaron Semler filed an application for the approval of Hillside Design Review DRC2015- 00604, as described in the title of this Resolution. Hereinafter in this Resolution, the subject Hillside Design Review request is referred to as "the application." 2. On the 14th day of February 2018, the Planning Commission of the City of Rancho Cucamonga conducted a noticed public hearing on the application and concluded said hearing on that date. 3. All legal prerequisites prior to the adoption of this Resolution have occurred. B. Resolution. NOW,THEREFORE, it is hereby found,determined,and resolved by the Planning Commission of the City of Rancho Cucamonga as follows: 1. This Commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct. 2. Based upon the substantial evidence presented to this Commission during the above-referenced public hearing on February 14,2018, including written and oral staff reports,together with public testimony, this Commission hereby specifically finds as follows: a. The applicant is requesting to construct a 3,778-square foot, 3-story single-family residence on the 23,320 square foot project site; and b. The project site and the properties to the east and west are undeveloped and within the Low(L) District. To lots to the north are developed with single-family residences and are within the Low(L) District. The property to the south is approved for a multi-family development and is within the Mixed Use (MU) District. The surrounding properties are all within the Hillside Overlay District; and c. The applicant is requesting site plan and architectural review of a single-family residence on the project site; and d. The project complies with the requirements of the Low (L) District and the Hillside Overlay District, including providing a grading design that balances the requirement to reduce cut and fill to the greatest extent possible and to reduce the height of the structure to limit view obstructions as seen from the residences to the north. The proposed design reduces the height of the structure to just over 8 feet above the curb face on Camino Predera and includes side yard setbacks that exceed the minimum requirement, also enhancing the views as seen from Camino Predera; and PLANNING COMMISSION RESOLUTION NO. 18-06 HILLSIDE DESIGN REVIEW DRC2015-00604 AARON SEMLER FEBRUARY 14, 2018 Page 2 e. The residence is stepped with the existing grade and includes a garage on the middle level,further reducing the overall bulk as seen from Camino Predera. Earthwork is limited to 158 cubic yards of export and grading is limited to the area necessary to construct the residence, driveway and patio/pool area to the south of the residence. The rear yard is left mostly undisturbed and is proposed to be planted with citrus trees. The proposed design does not require Variances or Minor Exceptions, and the square footage is in keeping with the more recent residences constructed along Camino Predera; and f. The residence is in compliance with Hillside Design Section 17.122.020.D.1.e.,which requires that residences in the Hillside Overlay District be designed to fit within a 30-foot high building envelope. The applicant has provided two north-south and two east-west cross-sections with building envelopes demonstrating compliance with the 30-foot height requirement; and g. Retaining walls are limited to a 4 foot retaining wall adjacent to southern edge of the driveway to the lower two-car garage space and two 4 foot high retaining walls necessary to construct short exterior stairways on either side of the residence. Hillside Development Section 17.122.020.G.1.J.ii permits up to 4-foot high retaining walls down slope from the residence. 3. Based upon the substantial evidence presented to this Commission during the above-referenced public hearing and upon the specific findings of facts set forth in Paragraphs 1 and 2 above, this Commission hereby finds and concludes as follows: a. The proposed project is consistent with the General Plan.The General Plan Land Use designation of the project site is Low (L) District. The Low residential designation is intended for the development of detached, low density residences on individual lots. The project is for the development of a single-family residence on an existing residential lot. b. The proposed use is in accord with the objective of the Development Code and the purposes of the district in which the site is located. The Development Code states that the Low (L) District is for the development of single-family residential uses with a minimum lot size of 7,200 square feet and a maximum residential density of 4 units per gross acre. The project site is an existing 23,320- square foot vacant lot that was intended for the development of a single-family residence. c. The proposed use is in compliance with each of the applicable provisions of the Development Code, including building setback, building height, lot coverage, grading limitations and design. The project complies with the requirements of the Low (L) District and the Hillside Overlay District. The required front yard setback is 37 feet (plus or minus 5 feet), the required side yard setbacks are 5 and 10 feet and the required rear yard setback is 20 feet. The proposed front yard setback is 33 feet, the side yard setbacks are 8 feet-9 inches and 20 feet, and the rear yard setback is 144 feet. Lot coverage is 11 percent, well below the maximum permitted lot coverage of 40 percent. The overall building height is 30 feet,which is at the maximum permitted height limit within the Hillside Overlay District. The proposed residence, as measured above curb face on Camino Predera, ranges in height from 4 to just over 8 feet, due to the falling grade of Camino Predera. The roof plan includes a 4- foot high elevator shaft and a 2-foot high chimney, both of which are exempt for the 30-foot height limit per Development Code Section 17.34.030.C.Grading is limited to 158 cubic yards of export from the project site,with the majority of the export necessary to lower the height of the residence as seen from Camino Predera. Earthwork is limited in the rear yard area to that necessary to construct a patio with a depth of 18 feet and a swimming pool. The remainder of the rear yard area has mostly been left undisturbed. The foundation of the residence is stepped with the existing grade,with the upper pad at PLANNING COMMISSION RESOLUTION NO. 18-06 HILLSIDE DESIGN REVIEW DRC2015-00604 AARON SEMLER FEBRUARY 14, 2018 Page 3 an elevation of 1,310 feet and the lower pad at an elevation of 1,301, in conformance with Hillside Design Section 17.122.020.D.1.a„ to terrace the building to follow the slope. Stepping the foundation necessitated the use of an up to 9 foot high retaining wall as part of the foundation of the residence, which is in conformance with Hillside Design Section 17.122.020.G.1.j.iv.,which permits retaining walls over 8 feet that are an integral part of the structure. d. The proposed use, together with the conditions applicable thereto, will not be detrimental to the public health, safety, or welfare, or materially injurious to properties or improvements in the vicinity. The proposed single-family residence is in keeping with the existing residences in the surrounding area and is not expected to create a detrimental impact on the existing residences. The size of the residence is in keeping with the square footage of homes constructed along Camino Predera since the year 2000, which range in size from 3,628 square feet to 4,896 square feet. The height of the residence was designed to limit view obstructions, as seen from Camino Predera, with a maximum building height of approximately 8 feet above the curb face on Camino Predera. 4. The Planning Department Staff has determined that the project is categorically exempt from the requirements of the California Environmental Quality Act(CEQA) and the City's CEQA Guidelines. The project qualifies as a Class 3 exemption under State CEQA Guidelines Section 15303, which permits the construction of a single-family residence in a residential zone. The project is for the construction of a single-family residence in a residential zone and there is no substantial evidence that the project may have a significant effect on the environment. The Planning Commission has reviewed the Planning Department's determination of exemption, and based on its own independent judgment, concurs in the staff's determination of exemption. 5. Based upon the findings and conclusions set forth in paragraphs 1, 2, 3, and 4 above, this Commission hereby approves the application subject to each and every condition set forth in the Standard Conditions, attached hereto and incorporated herein by this reference 6. The Secretary to this Commission shall certify to the adoption of this Resolution. APPROVED AND ADOPTED THIS 14TH DAY OF FEBRUARY 2018.
