APPENDIX A: MITIGATION MONITORING AND REPORTING PLAN <br />m iunatton Measure <br />00 <br />Imalumentatturtl Monixoring Entity ImDtementatlorl <br />. <br />Monitoring MeThod Schedule <br />t) Cut-off plugs consisting of controlled density fill about 2 feet wide and <br />fl <br />keyed into the native soils shall be installed at 25- to 50 -foot intervals <br />along all pipeline trenches and at the beginning, midpoints, and ends <br />C <br />of the culvert and all 36 -inch diameter detention pipes. Specific <br />recommendations for the cut-off plugs shall be presented in the <br />design -level geotechnical report. <br />u) All proposed structures shall be designed in accordance with the <br />seismic design criteria of the 2010 California Building Code (CBC) or <br />other recent applicable building code. <br />v) Cut areas in serpentinite and exposed fill slopes composed of <br />serpentinite rock shall be capped with asbestos free soil. <br />Mitigation Measure Geology -2: A design -level geotechnical investigation shall be <br />Building, <br />Building, <br />Prior to building <br />completed for each lot and for the utility improvements on Laurel Way. The <br />infrastructure, and <br />Infrastructure, and <br />permit issuance <br />geotechnical investigation shall include: <br />Transportation <br />Transportation <br />for Phase I <br />a) Evaluation of the layout of proposed underground utilities, exterior <br />Department to review <br />Department <br />activities, and <br />hardscape, and retaining walls to evaluate whether surFicial soil creep <br />design -level <br />prior to building <br />would impact these structures; <br />geotechnical <br />permit issuance <br />investigations and <br />for each <br />b) Detailed surface and subsurface explorations performed for each lot <br />ensure that the <br />residence in <br />during the design -level geotechnical investigation. Data from these <br />recommendations are <br />Phase Il <br />investigations shall be used to generate foundation design criteria; <br />implemented <br />c) Consideration of the need for extra steel reinforcement of piers and <br />grade beams, voids beneath grade beams to mitigate uplift distress to <br />the structures, perimeter subdrains and moisture barriers, and <br />measures implemented during construction to prevent concrete over - <br />pours at the tops of the drilled piers; and <br />d) Consideration of impacts arising from excavations of foundation <br />elements, including drilled piers. <br />Recommendations in the report shall be implemented, as approved by Redwood City. <br />At a minimum, the recommendations shall include: <br />a) Recommendations for mitigating slope instability during construction, if <br />necessary, by utilizing temporary excavation support systems or <br />grading controls; <br />hl RPrnmmP.nriatinnc for rnrrprtivp nrarlinn maasurPs to renlace existing <br />A-16 <br />Laurel Way Planned Development Revised Final EIR <br />February 2013 <br />
