ENVIRONMYNTAL1MPA01''NtYONT AUUYNVUN ARMSTRONG RAMI REVISED PROJECT' SEr'rENnSR.Y01]` SANTA AN ,-CALIPORNTA c) \o unique.geolpgic featines are present on the Project site; therefor e, the Revised Project would not result in the loss ofla unique geologic feature.and no mitigation is required, The Certified EIR alsodid not identify any unique geologicfeatures on the Project site. Therefore,.the.Revised Project would -not result in new significant impacts beyond those identified in the Certified E1R- No new mitieation measures are required. it) Asstaled above in Response 2.6..n.iv, there are no existing landslides or potential for landslides on the Project site. Therefore, theReAsed,Project'would not expose people or structures to advcisceffcicts involving landslide's and no mitigation.is required. As stated abo' cin Response 2AJi.iii, the Piclimihary Gcolechnioal Investigation Report,prepared for the Certified _EIR concluded that there is a low probability of lateral spreading, non -seismic related differential compaction, collapse, or liquefaction,to occur on the Pruiect site. Therefore, impacts related to lateral spreading would be less than significant and no mitigation is required. The Preliminary Gcowc hnical Investigation Report prepared for the Certified EIR also concluded that there is a low probabilityof nun seismic-relatucl,differential compaction to occur on the Projct site. The PrelintinaryGcolcchnical Investigation Report prepared fortis Certified EIR indicted that soils oil thNPro-ject site have a moderate potential for. cxpani iup. in addition, on-sitic soils may be severely corrosive when wct. Thercrprc, there is a potential for the Revised Project tolii: affc4:tcd by -strata or soil thatareor that would become unstable. The -Revised Projectwould be required to. comply with Mitigation MeasuresGEO-1 through GEO-4 from the.Certitied EIR. Mitigation Measure GEO-1 requires preparation of a final design geotechnical report and compliance with recommendations of the final design geotechnical report: Mitigation Measure GEO-2 requires compliance With the California Building Code, which stipulates appropriate seismic design provisions that shall be inmlentented with design and. construction of the Revised Project, Mitigation Measure GE0-3'requires sufftcientreinforcement of building fotting"s to mitigate -for impitctsrelated to expnnsi��e soils, Mitigation.Measitre Glib -4 requires that,a registered gcologiSL ensure that thatproject adheres to the recumtttendations or the final -design gcotcchnical report, hnplementaiion of Mitigation Measures GEU-1 through GE6-4 would reduce any potential impacts relatui to unstable soils to a lass than significant level. The Certified EIR also concluded Mitigation Measures GFOA through,GFO.4 would reduce irnpaels relined to unstable soils to a less than significant level, Therefore, the Revised Project would not result in new significant impacts beyond those identified in the Certified EIR. No neve mitigation measures are required. e) Similar to the Approvcd Projcct, the Revised Projcct d6eq not include construction of or connections to septic tanks or alternative wastewater disposal systems. Therefore; the Revised Project would not result in impacts related to the soil's capability to adequately support the use of septic tanks or alternative wastewater disposal systems, and no mitigation is required. Therefore, the Revised Project would not result in now signifieaut impacts beyond those identified in the Certified PTR. Therefore, pursuanl.lu,S1ate CEQ.4 Cruielcli ies Section 15162, the City may elect to prepare an, Addetidum to the FIR. I'ASI 1016045AJdrndum'�lddendu..,Iuux 4Y911)i47o 75B-81 a-32
