b) Does the project include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? (No Substantial Change from Previous Analysis) Construction of recreational amenities was considered in the FEIR. The project will have no new or more severe impacts beyond those addressed in the FEIR. Therefore, the FEIR remains complete and adequate as it relates to this topic. XVI. Transportation /Traffic A Traffic Study was prepared by Urban Crossroads in October 2003 and revised in October 2004 for the MacArthur Place South project. The FEIR included analysis based on that study. Urban Crossroads subsequently prepared a Trip Generation Evaluation (2009 Traffic Evaluation) dated April 1, 2009 for the 2009 Addendum, which analyzed traffic impacts resulting from the elimination of identified project components and the addition of a 185 -room hotel component. An updated traffic analysis has been prepared by KDA Corporation (2011 Traffic Study) dated February 2011 for the proposed modifications to the condominium component. The study analyzed data related to the increase in the number of residential units to determine the impact of expansion of the previously approved project. While the City's final approval was for a 155 -room hotel, the more conservative 185 -room analysis in the 2009 Addendum was used as the basis for analysis in this Addendum. The following information is based on the analysis contained in the traffic study, which is incorporated herein as Appendix B. a) Would the project cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? (No Substantial Change from Previous Analysis) The FEIR identified significant impacts due to the increase in traffic from the MacArthur Place South project. Mitigation Measures were included in the FEIR to minimize the impacts. The FEIR traffic study concluded that impacts to SR -55 on -ramps would be considered an unavoidable significant impact. The 2009 Traffic Evaluation by Urban Crossroads and the 2009 Addendum concluded that the proposed project would result in reduced trip generation for all timeframes evaluated as compared to the traffic analyzed in the 2005 FEIR. The reduction in traffic volumes was partly due to use of the optional alternative for high- and low -rise apartment units rather than condominium units. The 2011 Traffic Study used a study area that was determined based on the previous studies and through consultation with City of Santa Ana staff. Of the eight intersections included in the analysis, one is shared with the City of Costa Mesa, one is located within the City of Irvine, and two are under Caltrans jurisdiction. The following are the intersections identified for analysis: • Main Street at Dyer Road • Main Street at MacArthur Boulevard • Main Street at Sandpointe Avenue • Main Street at Sunflower Avenue (City of Costa Mesa) • MacArthur Place at MacArthur Boulevard • SR -55 SB Ramps at MacArthur Boulevard (Caltrans) • SR -55 NB Ramps at MacArthur Boulevard (Caltrans) • Red Hill Avenue at MacArthur Boulevard (City of Irvine) The 2011 Traffic Study scope was limited to intersection analysis only. No roadway segment average daily traffic (ADT) or ramp and freeway mainline analysis was conducted because extensive analysis was previously conducted and is not necessary based on the addition of 24 residential units (10 net MacArthur Place South EIR — 2011 Addendum 36
