THE CONSTRUCTION OF A NEW TWO-STORY RESIDENCE AT 27388 SHERLOCK COURT WHEREAS, The Town of Los Altos Hills received an application for a Site Development Permit (SD19-0003) from Edward and Kyuha Chung to allow for the construction of new 4,958 square -foot two-story residence with an attached garage and related hardscape improvements at 27388 Sherlock Court ("Project"); and WHEREAS, the Project is exempt from the provisions of the California Environmental Quality Act (CEQA) pursuant to Section 15301(c) which allows for the improvements to the fire access road and Section 15303(a) which exempts the construction of a new single-family residence in a residential zone; and WHEREAS, the Project application was processed in accordance with the applicable provisions of the California Government Code and the Los Altos Hills Municipal Code; and WHEREAS, the Planning Commission held a duly noticed public hearing on the Project on August 5, 2021 and considered all written documentation and public comments; and. WHEREAS, the Planning Commission voted 5-0 to continue the item to a date uncertain to allow the applicant to address Commission comments related to the road widening, skylights, exterior lighting, path and open space easements and impacts to the driveway on the adjacent property; and WHEREAS, the applicant resubmitted plans to address the Commission's comments; and WHEREAS, the Planning Commission held a duly noticed public hearing on the Project on January 13, 2022 and considered all written documentation and public comments. NOW, THEREFORE, the Planning Commission of the Town of Los Altos Hills hereby APPROVES the Site Development Permit (SD19-0003) subject to the Findings contained. in Exhibit "A" and the conditions contained in Exhibit "B" and incorporated herein by reference. The above and foregoing Resolution was passed and adopted by the Planning Commission of the Town of Los Altos Hills at a special meeting held on the 13th day of January 2022, by the following vote: AYES: Indaco, Waschura, Couperas, Smith NAYS: None ABSTAIN: None ABSENT: Patel Resolution PC 02-22 Page 1 ATTEST: By: C_ rgitta Indaco, Chair Sofia Mangalam, Planning and Building Director Resolution PC 02-22 Page 2 EXHIBIT A FINDINGS 1. With regard to the Site Development Permit (SD19-0003) to allow for anew two-story house at 27388 Sherlock Court, the Planning Commission finds in accordance with Section 10-2.102 of the Los Altos Hills Municipal Code as follows: a. The proposed development is in compliance with all regulations and policies set forth in the Site Development ordinance. The proposed new residence and associated improvements comply with all applicable regulations and policies set forth in the Site Development Ordinance because the project does not exceed maximum floor area and development area, is within the 27 -foot building height limit, meets or exceeds the existing building setbacks, and complies with all other applicable requirements in the Site Development Ordinance. 2. With regard to the Grading Policy exception request, the Planning Commission makes the following findings: a. There is a sufficient basis to support the Grading Policy exception to allow for fill that exceeds three feet for the lower, southwesterly portion of the residence and for cut that exceeds four feet for driveway and fire truck turnaround. Given the average slope of the lot (45.4 percent), any new development on this site would be significantly restricted without allowing some exceptions from the Town's Grading Policy. The grading work and export will not take place during the Town's grading moratorium (October 1 to April 30) and will be done in accordance with Town procedures for grading and construction operations. b. The proposed grading achieves the purpose of the Los Altos Hills Municipal Code Section 10-2.702(c) which states: "The amount of grading, excavation or fill shall be the minimum necessary to accommodate the proposed structures, unless grading is proposed to lower the profile of the buildings." The proposed grading for the driveway is necessary to accommodate a compliant fire truck turnaround and necessary to develop a residence on the existing slopes. In addition, the house has been cut into the slope with retaining walls integrated into the structure. c. The proposed grading will be consistent with grading provisions of the Site Development Ordinance, including Section 10-2.401 which states the intent to limit adverse effects from grading and Section 10-2.701 which states an intent to ensure that the site, location and configuration of structures are unobtrusive when viewed from off-site, that scenic views are retained, that buildings do not dominate the natural landscape and that ridgelines and hilltops are preserved. The proposed grading for the driveway and residence will be unobtrusive when viewed from off-site because the property is below the surrounding properties and there is sufficient vegetative cover to minimize visual impacts.

The applicant shall submit the stamped and signed letter(s) to the Planning Department prior to requesting a final inspection. ENGINEERING DEPARTMENT 31. As recommended by Cotton, Shires & Associates, Inc., in their letter dated February 2, 2019, the applicant shall comply with the following: 1. Supplemental Geotechnical and Geologic Site Characterization — The Project Geotechnical Consultant shall clarify the extent of existing grading in the vicinity of the residence site and roadway. The Project Geotechnical Consultant should prepare an Engineering Geologic Map of all site and roadway earth materials, including but not limited to: undocumented fill, colluvium, and bedrock. Existing cut slopes and any areas of previous instability should be appropriately labelled on the map. An Engineering Geologic Cross Section should be provided, trending N -S, illustrating the existing slopes and the configuration of earth materials in the vicinity of the proposed residence and driveway. It may be appropriate for the Project Geotechnical Consultant to utilize a Certified Engineering Geologist to complete the map and cross section. To complete the geologic mapping and cross section, additional subsurface exploration will be necessary to characterize the geometry and characteristics of site earth materials. Additional subsurface exploration should be advanced, at minimum, to the depth below the ground surface of which site improvements are proposed (including foundation supporting elements). Further site characterization may be warranted as deemed appropriate by the Project Geotechnical Engineer and/or Geologist. Subsurface exploration should conform to ASTM 1586 for small diameter borings, and test pits should be logged as a graphic drawing of the exposed and cleaned side wall with elevations, orientations, and contacts clearly depicted. Soil materials should be classified in accordance to the Unified Soil Classification System. We note that SW -ML is not a recognized soil material classification. 2. Supplemental Geotechnical and Civil Clarifications, Evaluations and Recommendations - The applicant's geotechnical and civil engineering consultant shall utilize the completed engineering geologic map and cross section to clarify the following in regards to site grading and site subsurface exploration: • The consultant shall clearly depict Standard Penetration Test values (N) on the new ASTM -1586 compliant borings. The Consultant should clarify what is interpreted to Resolution PC 02-22 Page 8 be artificial fill encountered in site borings and what is considered native soil material and/or bedrock. This clarification should be clearly labelled on provided boring logs. • The consultant shall clarify the intended retaining wall design recommendations and parameters. The minimum lateral support depth and minimum lateral cover for retaining wall foundation elements should be provided. The consultant should comment on whether shallow foundations are appropriate for retaining earth materials in a steep hillside setting. Local practice typically utilizes pier supported foundations. The consultant should comment on the maximum slope gradient intended to be retained by proposed walls. It appears that slopes steeper than 1.5H:1 V will be retained above the residence. Retaining wall surcharge loads should be considered between terraced walls. The Consultant should consider recommending a minimum freeboard height for walls retaining slopes of 2H:1 V, or steeper. • The consultant shall clarify whether existing site undocumented fill is to be completely removed and replaced as engineered fill for site roadway improvements. Appropriate modification to the roadway civil plans should be completed to illustrate the expected keys and benches for newly placed fill into competent material. • The consultant shall clarify whether existing undocumented fill will be removed and replaced, as warranted, from the vicinity of the proposed driveway, residence, and septic system. • The consultant shall clarify the recommended final slope gradients intended for site development. Any slopes composed of artificial engineered fill may not exceed 2H:1 V. Cut slopes in competent bedrock may be possibly be steeper if an engineering geologist finds rock properties (including discontinuity orientations) to be favorable. The Consultant should clarify whether slopes of 1.5H:1:V are appropriate between terraced retaining walls upslope of the residence. Appropriate laboratory testing and/or field evaluations should be submitted in support of final design recommendations. • The consultant shall clearly show the location of the slope stability cross sections on the site engineering geologic map at a scale of 1 " = 10' or 1 " = 20'. The consultant should also provide justification for the shear strengths and unit weights assigned to bedrock in the Slope Stability Analysis. While the Consultant indicates that a 3 -foot deep saturation zone was used in the analysis, there does not appear to have been a phreatic surface incorporated in the modelling. The Consultant should include a shallow phreatic surface in the slope stability analysis given the proximity to the leachfield. The Consultant should explain where fill will be placed in the slope stability cross sections and how the shear strength parameters are being modelled. • The Project Civil Engineer shall confirm that the submitted plans are at the correct scale. We note the grading and drainage plan (C1.0) is not at 20 -scale. The Project Civil Engineer shall revise the project plans to reflect the supplemental geotechnical recommendations. 32. Geotechnical Plan Review — The applicant's geotechnical consultant shall review and approve all geotechnical aspects of the project building and grading plans (i.e., site preparation and grading, site surface and subsurface drainage improvements, and design parameters for retaining walls and foundations, etc.) to ensure that their recommendations have been properly incorporated. The results of the plan review shall be summarized by the Resolution PC 02-22 Page 9 geotechnical consultant in a letter and submitted to the Town Engineer for review prior to issuance of the building permit. 33. Geotechnical Construction Inspection — The geotechnical consultant shall inspect, test (as needed), and approve all geotechnical aspects of the project construction. The inspections shall include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, and excavations for retaining walls and foundations prior to the placement of steel and concrete. The consultant shall review shoring design, as provided by the Contractor, if applicable during construction. The results of these inspections and the as -built conditions of the project shall be described by the geotechnical consultant in a letter and submitted to the Town Engineer for review prior to final inspection. 34. Any and all changes to the approved Civil Improvements plan shall first be approved by the Town Engineering Department. No grading shall take place during the grading moratorium (October 1st to April 30th) except with prior approval from the City Engineer. No grading shall take place within ten feet of any property line. 35. An encroachment permit shall be obtained from the Public Works Department for all work, proposed in the public right-of-way. No work within the public right-of-way shall commence without an encroachment permit. 36. All public utility services serving this property shall be placed underground. The applicant should contact PG&E immediately after issuance of building permit to start the application process for undergrounding utilities which can take up to 6-8 months. ROADWAY IMPROVEMENTS 37. A Grading Permit shall be required for the roadway improvements to widen Sherlock Road and Sherlock Court in conformance with the road improvement plans dated December 2020 and the Traffic Control plans dated August 2021.

At no time shall the roadway be closed to one-way traffic to ensure that residents continue to have access to their properties and to maintain fire safety access. PRIOR TO BUILDING PLAN CHECK: 38. Two copies of a Grading & Construction Operation plan shall be submitted by the property owner for review and approval by the City Engineer and Planning Director two weeks prior to acceptance of plans for building plan check. The grading/construction operation plan shall address truck traffic issues regarding dust, noise, and vehicular and pedestrian traffic safety on Sherlock Court, and surrounding roadways; storage of construction materials; placement of sanitary facilities; parking for construction vehicles; and parking for construction personnel. A debris box (trash dumpster) shall be placed on site for collection of construction Resolution PC 02-22 Page 10 debris. Arrangements must be made with the GreenWaste Recovery, Inc. for the debris box since they have a franchise with the Town and no other hauler is allowed within the Town limits. 39. The property owner shall provide the Town with high-quality color photographs of the existing conditions of the roadways and pathways two weeks prior to acceptance of plans for building plan check. 40. All hydrant use is strictly prohibited by the Purissima Hills Water District.
