declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or (3) 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 as complete or the negative declaration was adopted, shows any of the following: (A) The project will have one or more significant effects not discussed in the previous EIR or negative declaration; (B) Significant effects previously examined will be substantially more severe than shown in the previous EIR; (C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or (D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative. The California Environmental Quality Act states that a lead agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary, but none of the above-listed conditions in Section 15162 calling for the preparation of a subsequent.EIR have occurred. Staff believed that none of the conditions described in Section 15162 occurred. Therefore, an addendum to the SEIR was prepared for this project. The analysis in the attached Addendum to the SEIR (Exhibit E) determined that the proposed project will not trigger any new or more severe significant environmental impacts as compared to those analyzed in the context of the SEIR and confirmed that none of the conditions described in Section 15162 occurred. Therefore, the previously prepared SEIR and Addendum to the SEIR, taken together, are determined to be adequate to serve as the environmental documentation for this project and satisfy all the requirements of CEQA. The SEIR included some mitigation measures that needed to be addressed prior to issuance of a building permit for a project (e.g., pre-construction bat survey, air quality construction plan, etc). These mitigation measures have been addressed in the draft conditions of approval for this project. The SEIR included a Statement of Overriding Considerations for two significant and unavoidable impacts: Impact 4.D-1: Development facilitated by the General Plan Amendment and rezoning has the potential to adversely change the significance of historic resources.
