LSA ASSOCIATES, INC. MARCH 2002 ENVIRONMENTAL ANALYSIS ENVIRONMENTAL ANALYSIS AMENDMENT NO. 1 DISCOVER \'SCIENCE CENTER Section 15162 of the CEQA Guidelines provides the appropriate thresholds for a Lead Agency to determine whether a subsequent EIR is required for a minor change or addition to a project for which an approved EIR or Negative Declaration has been prepared. Under that analysis, no subsequent EIR or Negative Declaration shall be prepared fcr the project unless the Lead Agency (the City) determines: • That substantial chances are made to the project that require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects. • Substantial changes occur with respect to the circumstances under which the project is undertaken that will require major revisions to the previous EIR due to the involvement of new significant environmental effects cr a substantial increase in the severity of previously identified significant effects. X New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified, shows that (a) the project will have one or more significant effects not discussed in the previous EIR, or (b) that significant effects previously examined will be substantially more severe than as shown in the previous EIR, (c) that mitigation measures or alternatives that are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects m the environment but project proponents decline to adopt the mitigation measure or alternative, or (d) that mitigation measures or alternatives that are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects m the environment but project proponents decline toadopt the mitigation measure or alternative. The following analysis has been prepared in acccrdance with the findings required in Sectim 15162 of the CEQA Guidelines. The analysis is presented in the same order of environmental issues evaluated in FEIR 96 -01. Land Use Potential project -level and cumulative land use impacts associated with implementation of the DSC project were evaluated in FEIR 96 -01. Mitigation measures were included in FEIR 96 -01 to reduce potential land use impacts to a level considered less than siggiificant. The proposed project, to increase the amount of development area associated with DSC Phase H, would not change the type of land uses permitted in SD65 or evaluated in FEIR 96 -01. Implementation of the proposed project exceeds the maximum allowable development area permitted under SD65 but would be offset with the reduction in the seating of the proposed theater from 350 to 275 seats and would not result in new land use impacts beyond the impacts previously analyzed in FEIR 96 -01. The changes to the project would not result in conflicts with other applicable planning programs in the City of Santa Ana, nor would the proposed request substantially increase the severity of any land use impact identified in FEIR 96 -01.
