In general, <br /> these recommendations are expected to <br /> include the following requirements: <br /> • that all construction comply with the <br /> most current edition of the Uniform <br /> Building Code for Seismic Zone 4, or <br /> with the most recently adopted <br /> building codes; <br /> • that all project structural designs be <br />~ based on proper estimates by the <br />C project geotechnical engineer of <br />~ ~ peak and maximum repeatable <br />~ ~ earthquake-induced ground surface <br />~ accelerations expected to occur on <br />W CO the project site; and <br />Page 34 UaMy DocumentslDownfawn Precise Plan1CC staff repartslCC 3. f2doc13.12.07 ExhibitstAttachmenf A mil monitoring checklist 655.doc <br />
