I NPACT REPORT ADDSNDVY <br />BEPTEYR'2"Et], <br />Nlitigation ]Measures: <br />ARMSTRD NO RAN6N: VIS ED' CALIFORNIA' BANTA ANA, pDRNIA <br />Based on the analysis and information above, Mitigation Measures GEO-1 through GEO-6 included <br />in the Certified ElR for the Approved Project would be -applicable to the Revised Project. <br />GEO-1 A ficial design geotechnical report shall be prepared for the residential and church <br />development to provide sh'iictuie-specific geotechnical recommendations. The final <br />report shall address all issues initially covered in the Preliminary Geotechnical <br />Report. Final recommendations on earthwork, spread footings with slabs -on -grade, <br />reinforced mat foundations, post -tensioned mats, friction piles, cathedral retaining <br />(basement) walls, and measures to address soil corrosion shall be identified. The final <br />report shall specify foundation recommendations to ensure issues associated with <br />underlying soft, compressible clay Soils are addressed. Construction -of the e projeti t <br />shall comply with all recommendations in the final geotechnical report. <br />GEO-2 Structures shall be designed, in accordance with the 1994 California Building Code_ <br />to resist lateral loads due to strong enrlhquakes.al'this site, as specified in the <br />Geolechnical Report {scat Table 3 o(thaedocumeni). <br />GFo-3 To reduce the potential for damage due.to soil expansion; slabs -on -grade shall be <br />provided with sufficient reinforcement and the footings shall extend below the zone <br />of seasonal moisture fluctuation. Post -tensioned slabs -on -grade are another viable <br />alternative to effectively address effects -associated with expansivesoils. <br />GE04 A qualitied registered geologist shall (1) revie%vthe final construction plans and <br />specifications and (2) observe the earthwork and foundation installation in order to <br />ensure adherence to all recommendations. <br />GE0,5 'Phe applicant shall submit Notice of lntent(NOI) to the SNVRCB for coverage <br />under the Siatewide General Construction Activi4y Stormwater permit and shall <br />comply with all applicable requirements, including the preparation of aStormwaier <br />Pollution Prevention Plan. A copy the NOI shall be submitted to the City <br />Development Services Department prior to issuance of.a kading permit. <br />GEO-6 Erosion control practices shall be employed andmaintained on all vacant areas on the <br />prcject site that have been graded. <br />Findings Related to Geology -and Soilsi <br />No New Significant Effects Requiring Major Certified EiR Revisions. Based on the foregoing <br />analysis and information, there is no evidence that Project modilicalions require a major change to the <br />Certified E1R. The Project changes will not result in now significant environmental impacts related to <br />Geology and Soils, and there is substantial increase in the seventy orimpacis described in the <br />Certified Elk. <br />P"•SHOTGM17'_4ddcrdumWdJenamzduci t:.FI.�D5il7s <br />75B-82 <br />2-33 <br />
