Initial Study & Checklist continued9. Be located on expansive soils, as defined in Table 18, 1-B <strong>of</strong>the Uniform Building Code (1994), creating substantial risks tolife or property? (ESD)XDiscussion- Items VI-1,2:This project proposal will result in the disturbance <strong>of</strong> approximately 36.2-acres <strong>of</strong> the 1270-acre site for thedevelopment <strong>of</strong> the Homewood Master Resort. This includes the construction <strong>of</strong> various residential, tourist andcommercial buildings totaling approximately 1,161,148 square feet. Parking lots and circulation areas will beconstructed with the project.Grading activities are associated with the installation <strong>of</strong> the buildings and parking areas, retaining walls,roadway improvements, and underground utilities. To construct the proposed improvements, potentially significantdisruption <strong>of</strong> soils may occur, including excavation/compaction for roadways, building pads and various utilities. Theproject grading is expected to be approximately 194,700 cubic yards <strong>of</strong> cut to 51,300 cubic yards <strong>of</strong> fill. The projectproposes soil cuts <strong>of</strong> up to 27' maximum at 3:1 and fills <strong>of</strong> up to approximately 20' feet maximum with all resultingfinished grades to be no steeper than 2:1 at locations identified on the preliminary grading plan. According to theGeologic Hazards and Preliminary Geotechnical Evaluation by Kleinfelder, dated November 1, 2007, the maximumrecommended inclination <strong>of</strong> both cut and fill slopes is 3:1 for maximum heights <strong>of</strong> 20'.Construction <strong>of</strong> the proposed improvements may significantly disrupt the soils on the project site. The EIR forthis project will include an analysis <strong>of</strong> the potential for unstable earth conditions, soil disruptions, displacements,and compaction <strong>of</strong> the soil and provide mitigation measures to reduce these potential impacts.Discussion- Item VI-3:The project proposes soil cuts and fills <strong>of</strong> up to approximately 27 feet maximum with retaining walls up to 16 feet inheight, as identified on the preliminary grading plan. To construct the improvements proposed, substantial change intopography or ground surface relief features may occur. The proposed project’s impacts associated with topographyand relief features will be mitigated to a less than significant level by implementing the following mitigation measures:Mitigation Measures- Item VI-3:MM VI.1 The applicant shall prepare and submit Improvement Plans, specifications and cost estimates (per therequirements <strong>of</strong> Section II <strong>of</strong> the Land Development Manual [LDM] that are in effect at the time <strong>of</strong> submittal) to theEngineering and Surveying Department (ESD) for review and approval. The plans shall show all conditions for theproject as well as pertinent topographical features both on- and <strong>of</strong>f-site. All existing and proposed utilities andeasements, on-site and adjacent to the project, which may be affected by planned construction, shall be shown on theplans. All landscaping and irrigation facilities within the public right-<strong>of</strong>-way (or public easements), or landscaping withinsight distance areas at intersections, shall be included in the Improvement Plans. The applicant shall pay plan checkand inspection fees. Prior to plan approval, all applicable recording and reproduction cost shall be paid. The cost <strong>of</strong> theabove-noted landscape and irrigation facilities shall be included in the estimates used to determine these fees. It is theapplicant's responsibility to obtain all required agency signatures on the plans and to secure department approvals. Ifthe Design/Site Review process and/or DRC review is required as a condition <strong>of</strong> approval for the project, said reviewprocess shall be completed prior to submittal <strong>of</strong> Improvement Plans. Record drawings shall be prepared and signed bya <strong>California</strong> Registered Civil Engineer at the applicant's expense and shall be submitted to the ESD prior to acceptanceby the <strong>County</strong> <strong>of</strong> site improvements.MM VI.2 All proposed grading, drainage improvements, vegetation and tree removal shall be shown on theImprovement Plans and all work shall conform to provisions <strong>of</strong> the <strong>County</strong> Grading Ordinance (Ref. Article 15.48,<strong>Placer</strong> <strong>County</strong> Code) that are in effect at the time <strong>of</strong> submittal. No grading, clearing, or tree disturbance shall occur untilthe Improvement Plans are approved and all temporary construction fencing has been installed and inspected by amember <strong>of</strong> the DRC. All cut/fill slopes shall be at 2:1 (horizontal:vertical) unless a soils report supports a steeper slopeand the Engineering and Surveying Department (ESD) concurs with said recommendation.The applicant shall revegetate all disturbed areas. Revegetation undertaken from April 1 to October 1 shall includeregular watering to ensure adequate growth. A winterization plan shall be provided with project Improvement Plans. It isthe applicant's responsibility to assure proper installation and maintenance <strong>of</strong> erosion control/winterization duringproject construction. Where soil stockpiling or borrow areas are to remain for more than one construction season,proper erosion control measures shall be applied as specified in the Improvement Plans/Grading Plans. Provide forerosion control where roadside drainage is <strong>of</strong>f <strong>of</strong> the pavement, to the satisfaction <strong>of</strong> the ESD.Submit to the ESD a letter <strong>of</strong> credit or cash deposit in the amount <strong>of</strong> 110% <strong>of</strong> an approved engineer's estimate forwinterization and permanent erosion control work prior to Improvement Plan approval to guarantee protection againsterosion and improper grading practices. Upon the <strong>County</strong>'s acceptance <strong>of</strong> improvements, and satisfactory completion<strong>of</strong> a one-year maintenance period, unused portions <strong>of</strong> said deposit shall be refunded to the project applicant orauthorized agent.PLN=Planning, ESD=Engineering & Surveying Department, EHS=Environmental Health Services, APCD=Air Pollution Control District 8 <strong>of</strong> 21
