Queuing Analysis A queuing analysis was included in the 201.1 Traffic Study to determine if vehicles traveling northbound on Main Street would be delayed due to the right -turn movement into and from the project. As indicated on the 2011 Site Plan (Exhibit 6), the project will have two access points along both Main Street and MacArthur Boulevard. The signalized intersection at MacArthur Boulevard and MacArthur Place is the main access point, followed by the signalized intersection of Main Street and Sandpointe Avenue. Right -in and right -out driveways will be located along MacArthur Boulevard between Main Street and MacArthur Place and along Main Street between Sandpointe Avenue and MacArthur Boulevard. No gate control is proposed at the driveway locations. The queuing analysis was conducted using Synchro software and included adjusted trip distribution. Analysis included year 2013 with Project conditions and year 2035 with Project Conditions. Because the project will have a total of four access points, with the maj ority of project trips using the signalized intersection of MacArthur Place at MacArthur Boulevard, the analysis assumed that 10% of the project trips will make the right -turn movement from the project driveway onto Main Street. Queuing analysis worksheets are included in the Traffic Analysis which is included as Appendix B herein. 2013 With Project Conditions — The analysis showed that for the AM Peak Hour, 9 vehicles (approximately 1 vehicle every 6 minutes 40 seconds) would make a northbound right -turn movement onto the driveway. For the PM Peak Hour, there would be 20 vehicles (approximately 1 vehicle every 3 minutes) making the turn. The analysis concluded that based on the low project turning; volumes, there will be no queue for the northbound right -turn movement for either the AM or PM Peak Hours and no impact will occur. 2035 With Project Conditions — The analysis showed the for the AM Peak Hour, 10 vehicles (approximately 1 vehicle every 10 minutes) would make the northbound right -turn movement. For the PM Peak Hour, 23 vehicles (approximately 1 vehicle every 2 minutes 37 seconds) would make the right -turn movement. The conclusion based on the analysis is that there will be no queue for the northbound right -turn movement for either the AM or PM Peak Hour in year 2035 and, therefore, no impact will occur. b) Would the project exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? (No Substantial Change from Previous Analysis) The FEIR addressed traffic impacts to surrounding streets and freeways. Mitigation measures were included to reduce impacts. Fair share contributions towards proposed improvements will reduce impacts to a less than significant level. The 2009 Addendum concluded that the project would result in fewer daily trips than the project analyzed in the FEIR, and no new or more significant impacts will occur. As determined in the KOA 2011 Study and detailed in section a) above, the modifications to the project proposed herein will not exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways. Therefore, the FEIR remains complete and adequate. c) Would the project result in a change in air traffic: patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? (No Substantial Change from Previous Analysis) No change in air traffic patterns will occur as a result of the proposed project. Therefore, the FEIR remains complete and adequate as it relates to this topic. MacArthur Place South EIR — 2011 Addendum 43
