ENVIRONMENTAL IMPACT REPORTADDENDUM Bristol Street Widening Project Warner Ave to Saint Andrew Place (Phase IV) West Saint Gertrude Place and Saint Andrew Place. Using the California Department of Transportation's (Caltrans) May 2011 Traffic Noise Analysis Protocol, the following noise barriers (NB) were determined to be reasonable: NB -4, NB -5, NB -6, NB -7, NB -8, NB -9, NB -10, and NB -11. These noise barriers are generally equivalent to the recommended noise barriers shown in the 1990 FEIS and 2013 Reevaluation. However, barriers NB -6, NB -7, NB -8, and NB -9 would need to be shifted to the west of the receivers (parcels) that are no longer being acquired. The modifications and other refinements to the project would not create any additional impacts than what was identified in the 2013 NEPA Reevaluation; thus, there would be no changes or additions to the avoidance, minimization, and/or mitigation measures. Furthermore, as climate change is a relatively new area of discussion, the topic was not discussed in the Air Quality section of the previously approved FEIS /EIR. As such, this Addendum analyzes the effects of climate change associated with the construction and operation of the Project. This Addendum to the previously certified 1990 Final EIS /EIR has been prepared because project - related modifications to the Bristol Street alignment do not trigger the need for further environmental analysis in a Subsequent or Supplemental EIR under the requirements of CEQA or CEQA Guidelines (refer to CEQA Guidelines Sections 15164 and 15167). 1.1 Purpose of an Addendum Under CEQA, when an EIR has been certified for a project, no Subsequent FIR may be required for that project unless the lead agency determines, based upon substantial evidence, that one or more specified circumstances has occurred. Only if one or more of the following circumstances arises is a Subsequent FIR required: 1) Substantial changes are proposed in the project which will require major revision 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; 2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revision of the previous EIR due to the involvement of new significant environmental 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, shows any of the following: A) The project will have one or more significant effects not discussed in the previous EIR; 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. (CEQA Guidelines Section 15162[a]) A Supplement to an FIR (or Supplemental EIR), which is narrower in scope than a Subsequent EIR, may be prepared if any of the above criteria apply, but "[o]nly minor changes or additions would be necessary to make the previous EIR adequately apply to the project in the changed situation" (CEQA Guidelines Section 15163[a]). In the absence of the need to prepare either a Subsequent or Supplemental EIR, an Addendum may be prepared. Section 15164 states: ANA 305 -194 (PER 02) CSA (AUGUST 2014) 133867 YU 75C -12
