(Application No(s).: EXC-2020- 001; Applicant(s): Janet De Carli; Location: 11640 Regnart Canyon Dr.; APN(s): 366-33- 006) RECOMMENDED ACTIONS That the Planning Commission adopt the proposed draft resolution to: 1. Find the project exempt from CEQA; and 2. Approve the Hillside Exception (EXC-2020-001) (Attachment 1) DISCUSSION Project Data: General Plan Designation: Very Low Density (5-20 Acre Slope Density Formula) Zoning Designation: RHS-120 (Residential Hillside with minimum net lot area of 120,000 sq.ft.) Lot Area 179,467 sq. ft. (4.12 acres) Project Data Allowed Existing Proposed Total Grading Quantity (cubic yards) 2,500 cu. yd. max., exclude basements 1,150 cu. yds 155 cu. yds 1,305 cu. yds Flat Yard Area (square feet) 2,500 sq. ft. max., exclude driveways 556 sq. ft. 750 sq. ft. 1,306 sq. ft. Project Consistency with: General Plan: Yes Zoning: Yes, with approved Hillside Exception Environmental Assessment: Categorically Exempt per Section 15303 (Class 3) of the California Environmental Quality Act (CEQA) construction or conversion of small facilities or structures. Background: The project site (Figure 1) is located within the Monta Vista South neighborhood in a Residential Hillside (RHS) zoning district and is surrounded by hillside single-family residences to the north, east, south, and west. The RHS district is intended to balance residential uses with preserving natural settings and protecting life and property from natural hazards. The property is accessed by Regnart Canyon Drive, a private street. The site contains a 6,171-square-foot two-story residence, as well as a water tower, and a cell tower. The property has been developed since 1981. Proposed Project The applicant, and property owner, Janet De Carli, is proposing to expand an existing 556 sq. ft. patio along the eastern edge of the home to a 750 sq. ft. patio and 950 sq. ft. swimming pool. The developed patio will be supported by offset retaining walls, with landscaping and screening vegetation planted between the offset retaining walls. The pool is designed as an infinity pool with three levels; the top level will be a rim flow spa which spills into the infinity vanishing edge pool. The pool then cascades into a lower trough. The pool has a maximum depth of four feet. The new patio area will be slightly below the trough and designed to have an unobstructed view of the Santa Clara Valley. Surrounding the new patio and pool will be enhanced low water use landscaping. Three 24”-box Coast Live Oaks will be planted downslope from the patio and pool. No trees will be removed. Hillside Exception: The RHS Ordinance, Chapter 19.40 of the Cupertino Municipal Code, prohibits any structures that disrupt a 15% site line from a prominent ridgeline and any structures or improvements over 500 square feet in area on slopes greater than 30% unless an exception is granted. The intent of the requirement is to minimize and discourage unnecessary hillside grading activities and visual disturbances. However, if the project/property presents unique circumstances or hardships (typically physical/topographic challenges), Figure 1 Site Aerial then the City may consider an exception provided that the project is designed to minimize the extent of the exception and impacts to the surrounding hillside. The City has historically granted exceptions to allow reasonable development of steeper hillside properties planned for residential use. The subject property is located along a prominent ridgeline (see Figure 2). In addition, much of the property has slopes greater than 30% (see Figure 3). Therefore, almost any development on the property, including the addition of any type of accessory structure such as the proposed pool or patio, cannot be feasibly constructed on the property without a hillside exception request. The siting and design of the proposed structure minimizes grading as it is adjacent to the house and existing patio, which eliminates the need for pathways to the structure. Figure 2 Prominent Ridgeline Figure 3 Slope Percentage over 30% Previous conditions of approval required the planting of trees to screen the existing building on the property. While reviewing a prior application (M-2008-01), which was approved but never built, it was discovered that the trees required for screening had been topped and/or removed. To mitigate this issue, the Planning Commission with Resolution 6514 had required the replacement of those trees as a condition of approval. In reviewing the landscape plans submitted by the applicant, it appears that those required trees had not been planted. Furthermore, while the applicant is proposing to plant three oak trees further downslope to screen the new patio and pool, it is not anticipated that these will help with screening the existing two-story home. Therefore, a condition of approval has been added to the draft resolution for the current project to require replacement of the topped trees in a manner to screen the existing two-story home. Except for the proposed development into the 15% site line of the prominent ridgeline and on slopes greater than 30%, the proposed patio and pool complies with all other aspects of the RHS zone’s site development regulations. The development will be constructed with appropriate geotechnical review and inspections as described below. Geological Review: The property is in a hillside and slope instability geologic hazard zone. The City’s Geotechnical Consultant has peer-reviewed the applicant’s geotechnical reports and has concluded that the project is feasible from a geologic standpoint. Their recommendations have been added as conditions of approval. Environmental Assessment: The project is categorically exempt from the requirements of the California Environmental Quality Act of 1970 (Public Resources Code section 21000 et seq.) (“CEQA”), together with the State CEQA Guidelines (California Code of Regulations, Title 14, Section 15000 et seq.) (hereinafter, "CEQA Guidelines"), pursuant to CEQA Guidelines section 15303. The exemption applies to new construction or conversion of small facilities or structures, including single-family residences (see CEQA Guidelines § 15303(a)) and accessory structures, such as patios and swimming pools (see CEQA Guidelines § 15303(e)), and none of the exceptions to the categorical exemptions in CEQA Guidelines section 15300.2 apply. Other Department/Agency Review: The City’s Building Division, Public Works Department, and the Santa Clara County Fire Department have reviewed and conditionally approved the project. Their pre-hearing comments/conditions have been incorporated as conditions of approval in the draft resolution (Attachment 1). PUBLIC NOTICING & OUTREACH The following table is a brief summary of the noticing done for this project: Public Notice Agenda  Site Signage (14 days prior to the hearing)  Legal ad placed in newspaper (at least 10 days prior to the hearing)  15 public hearing notices mailed to property owners within 300 feet of the project site (10 days prior to the hearing)  Posted on the City’s official notice bulletin board (one week prior to the hearing)  Posted on the City of Cupertino’s website (one week prior to the hearing) No public comments have been received as of the date of production of this staff report (August 20, 2020). PERMIT STREAMLINING ACT This project is subject to the Permit Streamlining Act (Government Code Section 65920 – 65964). The City has complied with the deadlines found in the Permit Streamlining Act. Project Received: January 15, 2020; Deemed Incomplete: February 11, 2020 Project Resubmission: July 6, 2020; Deemed Complete: July 20, 2020 Since this project is Categorically Exempt, the City has 60 days (until September 20, 2020) to decide on the project. CONCLUSION The lot is surrounded by existing hillside single-family residences and any onsite development that disrupts the 15% site line of the prominent ridgeline and/or is greater than 500 square feet on a slope greater than 30% would require a Hillside Exception. Development cannot feasibly occur on the property without a Hillside Exception request as the site is constrained by a prominent ridgeline. The ridgeline runs along the northern portion of the property and is virtually entirely sloped greater than 30%. The location and design of a proposed patio and pool will follow the contours of the site to minimize grading, minimize the removal of landscaping, and reduce the visibility of retaining walls necessary on site to develop the property in a manner consistent with the Residential Hillside Ordinance. A geotechnical study has been conducted for the proposed project and all recommendations of the geotechnical consultant have been incorporated into the development conditions of the approval. Staff recommends approval of the Hillside Exception since the plans and conditions of approval address all concerns related to the proposed project. Additionally, all the findings for approval of the proposed project, consistent with Chapter 19.40 of the Cupertino Municipal Code have been met. NEXT STEPS Should the project be approved, the Planning Commission’s decision on this proposal is final unless an appeal is filed within 14-calendar days of the date of the mailing of the decision on August 25, 2020. The applicant may apply for building and other permits at the end of the appeal period to complete installation of the proposed signs. This approval expires on August 25, 2021, at which time the applicant may apply for a one-year extension.

(“CEQA”), together with the State CEQA Guidelines (California Code of Regulations, Title 14, Section 15000 et seq.) (hereinafter, "CEQA Guidelines"), the City staff has independently studied the proposed Project and has determined that the Project is exempt from environmental review pursuant to the categorical exemption in CEQA Guidelines section 15303 for the reasons set forth in the staff report dated August 25, 2020 and incorporated herein; and WHEREAS, on August 25, 2020, the Planning Commission held a duly noticed public hearing to receive public testimony on the Project, including the categorical CEQA exemption in CEQA Guidelines section 15303, and reviewed and considered the information contained in the staff report pertaining to the Project, all other pertinent documents, and all written and oral statements received by the Planning Commission at or prior to the public hearing; and Draft Resolution EXC-2020-001 August 25, 2020 Page 2 WHEREAS, the applicant has met the burden of proof required to support said application; and WHEREAS, the Planning Commission finds as follows with regard to this application: 1. The proposed development will not be injurious to property or improvements in the area nor be detrimental to public health and safety; The proposed site is surrounded by existing hillside single-family residences. A geotechnical study has been conducted for the proposed project and all recommendations of the geotechnical consultant have been incorporated into the development conditions of the approval. In addition, the development is required to meet the Best Management Practices (BMPs), as required by the State Water Resources Control Board and the Bay Area Air Quality Management District’s (BAAQMD) air quality standards for construction activities. The project is also required to adhere to the City’s C.3 Municipal Permit for storm water runoff management. Therefore, the development will not be injurious to property or improvements in the area nor be detrimental to the public health and safety. 2. The proposed development will not create a hazardous condition for pedestrian or vehicular traffic; The proposed patio and swimming pool will not any new traffic impacts and/or driveways to the private raod. Therefore, the development will not create a hazardous condition for pedestrian or vehicular traffic. 3. The proposed development has legal access to public streets and public services are available to serve the development; The property is accessed by the private Regnart Canyon Drive. In addition, water and sewer connections are available in the street. The proposed project does not propose any changes to such access or services. Therefore, the development has legal access to public streets and public services to serve the development. 4. The proposed development requires an exception which involves the least modification of, or deviation from, the development regulations prescribed in this chapter necessary to accomplish a reasonable use of the parcel; Any onsite development that disrupts the 15% site line of the prominent ridgeline and construction of a structure greater than 500 sf on slopes gretare than 30% requires a Hillside Exception. Development cannot feasibly occur on the property without a Hillside Exception request as the site is constrained by a prominent ridgeline that runs along the northern portion of the property. The site is constrained by steep slopes over 30%. The siting and design of the accessory structures will follow the contours of the site to minimize grading, Draft Resolution EXC-2020-001 August 25, 2020 Page 3 minimize the removal of landscaping and reduce the visibility of retaining walls necessary on site to develop the property in a manner consistent with the Residential Hillside Ordinance. 5. All alternative locations for development on the parcel have been considered and have been found to create greater environmental impacts than the location of the proposed development; The proposed development will be located on a relatively flat and previously graded portion of the property in order to avoid excessive grading of the site adjacent to the existing single family home. Further, the site is constrained by steep slopes that limit areas on the parcel where development may occur. The siting and design of the accessory structure will follow the contours of the site to minimize grading, minimize the removal of landscaping and reduce the visibility of all retaining walls necessary to develop the property in a manner consistent with the purpose of the Residential Hillside Ordinance. Other alternative locations for development on the parcel would result in greater grading on the site and removal of additional landscaping and/or native trees. The proposed development is located to minimize environmental and grading impacts on the site. 6. The proposed development does not consist of structures on or near known geological or environmental hazards which have been determined by expert testimony to be unsafe or hazardous to structures or persons residing therein (See General Plan Policies 2-49); The geotechnical report and peer review do not indicate any significant conflicts with geological or environmental hazards. Additionally, all recommendations of the geotechnical engineers have been incorporated into the conditions of approval in order to ensure structural stability of the proposed building. Therefore, the proposed development does not consist of structures that have been determined by expert testimony to be unsafe or hazardous to structures or persons residing therein. 7. The proposed development includes grading and drainage plans which will ensure that erosion and scarring of the hillsides caused by necessary construction of roads, housing sites, and improvements will be minimized (See General Plan Policies 2-53, 2-54 and 2-57); The proposed development follows, as closely as possible, the primary natural contours of the lot to minimize erosion and scarring of the hillsides caused by necessary construction of the housing site and improvements. Drainage and grading plans have been reviewed and will continue to be reviewed by the City Engineer and the City’s consultant geotechnical engineers to ensure the safety of the development and of those neighboring residences. Draft Resolution EXC-2020-001 August 25, 2020 Page 4 8. The proposed development does not consist of structures which would disrupt the natural silhouette of ridgelines as viewed from established vantage points on the valley floor unless either: a. The location of a structure on a ridgeline is necessary to avoid greater negative environmental impacts; or b. The structure could not otherwise be physically located on the parcel and the size of the structure is the minimum which is necessary to allow for a reasonable use of the parcel (See General Plan Policies 2-46, 2-47 and 2-48); There is a potential that the addition of the pool and patio could disrupt the natural silhouette of the ridgeline. However, because the proposed development will be located adjacent to the existing single family home, it not only avoids excessive grading of the site, but the silhouette disruption will be negligeable. Further, the site is constrained by steep slopes that limit areas on the parcel where development may occur. The siting and design of the accessory structures will follow the contours of the site to minimize grading, minimize the removal of landscaping and reduce the visibility of all retaining walls necessary to develop the property in a manner consistent with the purpose of the Residential Hillside Ordinance. Additionally, to address screening issues with regard to the existing two-story structure and fix a prior violation, the applicant is being required to plant screening trees. Other alternative locations for development on the parcel would result in greater grading on the site, removal of additional landscaping and/or native trees. The proposed development will be located to minimize environmental and grading impacts on the site. 9. The proposed development consists of structures incorporating designs, colors, materials, and outdoor lighting which blend with the natural hillside environment and which are designed in such a manner as to reduce the effective visible mass, including building height, as much as possible without creating other negative environmental impacts (See General Plan Policies 2-46, 2-50, 2-51 and 2-52); The applicant is required to use natural earth tone and/or vegetation colors, which blend with the natural hillside environment (as a condition of approval) and has designed the project in such a manner as to reduce the effective visible mass to surrounding neighbors as much as possible. 10. The proposed development is located on the parcel as far as possible from public open space preserves or parks (if visible there from), riparian corridors, and wildlife habitats unless such location will create other, more negative environmental impacts (See General Plan Policies 2-55, 5-14 and 5-28); Draft Resolution EXC-2020-001 August 25, 2020 Page 5 The parcel is not located adjacent to public open space preserves, parks, a riparian corridor, or wildlife habitats. The project site is adjacent to other developed properties with a similar zoning. 11. The proposed development includes a landscape plan, which retains as many specimen trees as possible, which utilizes drought-tolerant native plants and ground covers consistent with nearby vegetation, and which minimizes lawn areas (See General Plan Policies 2-54, 5-15 and 5-16); A preliminary landscape plan has been evaluated and the project is conditioned to provide a landscape plan to be reviewed and approved prior to Building Permit issuance. The project shall also comply with Chapter 14.15: Landscape Ordinance of the City of Cupertino Municipal Code (CMC). Additionally, since the site is located in an area designated as Wildland Urban Interface by CMC Chapter 16.74, fire-prone plant materials and highly flammable mulches are strongly discouraged. In conformance with California Public Resources Code Section 4291, plants shall be selected, arranged, and maintained to provide defensible space for wildfire protection. The installation of invasive plant species and noxious weeds is also prohibited. Further, Residential Hillside homes are required to minimize turf areas on hillsides and turf may not be planted on slopes greater than 25%. Through the proposed site design and conditions of approval, which limit invasive species of plants and turf areas, a balance between the residential development and preservation of the natural hillside setting can be maintained. 12. The proposed development confines solid fencing to the areas near a structure rather than around the entire site (See General Plan Policy 5-17); and To allow free movement of animals, in compliane with the RHS fencing standards, only 5,000 square feet (excluding the principal building) of net lot area may be enclosed with solid fencing. 13. The proposed development is otherwise consistent with the City's General Plan and with the purposes of this chapter as described in Section 19.40.010. The development meets all the development standards for RHS zoned properties and is consistent with the City's General Plan and with the purposes of Chapter 19.40 as described in Section 19.40.010. These have been described in detail in each of the findings above. WHEREAS, the Planning Commission has independently reviewed and considered the Project and the basis for the exemption prior to taking any approval actions on the Project, and exercising its independent judgment, based upon the entire record before it, has determined that the Project is exempt from CEQA pursuant to CEQA Guidelines Draft Resolution EXC-2020-001 August 25, 2020 Page 6 section 15303, which applies to new construction or conversion of single-family residences and accessory structures; and WHEREAS, the Planning Commission determined that the project is categorically exempt in accordance with CEQA Guidelines sections 15303; and NOW, THEREFORE, BE IT RESOLVED that the Planning Commission takes the following actions: 1.

SECTION IV: CONDITIONS ADMINISTERED BY THE PUBLIC WORKS DEPARTMENT Draft Resolution EXC-2020-001 August 25, 2020 Page 10 1. GRADING A grading permit is required for the proposed free-standing retaining walls that are greater than four feet (including foundation). Grading shall be as approved and required by the Director of Public Works in accordance with Chapter 16.08 of the Cupertino Municipal Code. 401 Certifications and 404 permits maybe required. Please contact Army Corp of Engineers and/or Regional Water Quality Control Board as appropriate. 2. DRAINAGE Drainage shall be provided to the satisfaction of the Director of Public Works. Hydrology and pre- and post-development hydraulic calculations must be provided to indicate whether additional storm water control measures are to be constructed or renovated. The storm drain system may include, but is not limited to, subsurface storage of peak stormwater flows (as needed), bioretention basins, vegetated swales, and hydrodynamic separators to reduce the amount of runoff from the site and improve water quality. The storm drain system shall be designed to detain water on- site (e.g., via buried pipes, retention systems or other approved systems and improvements) as necessary to avoid an increase of the ten percent flood water surface elevation to the satisfaction of the Director of Public Works. Any storm water overflows or surface sheeting should be directed away from neighboring private properties and to the public right of way as much as reasonably possible. 3. FEES AND BONDS The project developer shall provide payment of fees, including but not limited to checking and inspection fees, storm drain fees, park dedication fees and fees for under grounding of utilities. Said fees shall be executed and paid prior to issuance of Building permit. Fees: a. Checking & Inspection Fees: Per current fee schedule ($891) b. Grading Permit: Per current fee schedule ($3,059 or 6% of improvement costs) c. Storm Drainage Fee: Per current fee schedule ($3,645 per DU) Bonds: a. On-site Grading Bond: 100% of site improvements. The fees described above are imposed based upon the current fee schedule adopted by the City Council. However, the fees imposed herein may be modified at the time of recordation of a final map or issuance of a building permit in the event of change or changes, the fees changed at that time will reflect the then current fee schedule. 4. BEST MANAGEMENT PRACTICES Draft Resolution EXC-2020-001 August 25, 2020 Page 11 Utilize Best Management Practices (BMPs), as required by the State Water Resources Control Board, for construction activity, which disturbs soil. BMP plans shall be included in grading and street improvement plans. 5. EROSION CONTROL PLAN Developer must provide an approved erosion control plan by a Registered Civil Engineer. This plan should include all erosion control measures used to retain materials on site. Erosion control notes shall be stated on the plans. 6. WORK SCHEDULE Every 6 months, the developer shall submit a work schedule to the City to show the timetable for all grading/erosion control work in conjunction with this project. 7. DEDICATION OF UNDERGROUND WATER RIGHTS Developer shall “quit claim” to the City all rights to pump, take or otherwise extract water from the underground basin or any underground strata in the Santa Clara Valley. 8. UPDATED GEOTECHNICAL INVESTIGATION The Project Geotechnical Consultant should perform a focused geotechnical investigation of the proposed retaining wall and pool development, including, but not limited to, the following items:  Subsurface investigation should be performed to span the limits of the retaining wall footprint area to assure that the subsurface geologic materials have been adequately characterized. The proposed development spans over 100 feet of distance across the ridgeline, with variable fill and colluvial soil depths, and thus, warrants further subsurface exploration.  Retaining wall and pool foundation recommendations should be provided. Swimming pool recommendations have been provided in the referenced geotechnical report, including recommendations for supporting the pool shell on reinforced concrete piers extending a minimum of 5 feet into bedrock. It is our opinion that the minimum pier embedment depth into rock should be re- evaluated, particularly with the combined thickness of existing fill and colluvial soil exceeding 6 feet in the one exploratory boring, and laboratory test results that demonstrate moderate to highly expansive soil and rock.  Hillside stability should be evaluated based upon the surcharge loads imposed from the proposed retaining walls. 9. STRUCTURAL PLANS AND CALCULATIONS Structural plans and calculations should be generated that incorporate the recommendations of the Project Geotechnical Consultant. Draft Resolution EXC-2020-001 August 25, 2020 Page 12 10. GEOTECHNICAL PLAN REVIEW The applicant's geotechnical consultant should review and approve all geotechnical aspects of the development plans (i.e., site preparation and grading, site drainage improvements and design parameters for foundations, drainage, pavement and retaining walls) to ensure that their recommendations have been properly incorporated. The Updated Geotechnical Investigation, Structural Plans and Geotechnical Plan Review should be submitted to the City for review and approval by the City staff and City Geotechnical Consultant prior to issuance of building permits. 11. GEOTECHNICAL FIELD INSPECTION The geotechnical consultant and engineering geologist should inspect, test (as needed), and approve all geotechnical aspects of the project construction. The inspections should include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements and excavations for foundations and retaining walls prior to the placement of steel and concrete. The results of these inspections and the as-built conditions of the project should be described by the consultants in a letter and submitted to the City Engineer for review prior to final project (as-built) approval.
