A&F Engineering Co., LLC ~ 9 ~' RE: Additional Analysis for Burlingame A&F Engineering has completed a supplemental traffic analysis for the proposed Burlingame residential site. This analysis is in addition to the original traffic study prepared in September 2003 for the subject site. Per the request of the Ciry of Carmel Plan Commission, the additional analysis addressed issues surrounding the existing and future traffic conditions at 116`h Street and Shelborne Road. A total of four traffic scenarios were studied as part of the original traffic study. The first three scenarios analyzed the existing traffc volumes with a variety of different geometric conditions at the intersection. On the other hand, the fourth scenario analyzed future traffic conditions and the alignment of the intersection. The results of these scenarios revealed that the intersection of 116`h Street and Shelborne Road should be aligned and additional improvements (lane improvements, signal installation) could be warranted within the near future. However, no results were presented that addressed the operations of this intersection if it was not aligned and future traffic was added to the roadway network. Therefore, additional analyses were conducted to determine the impact of future traffic on the unaligned intersection. The following table summarizes the level of service results from the original study (shown in blue) as well as the results from the supplemental analysis (shown in red). In addition, the attached tigures illustrate the traffic volumes and intersection configurations used for each scenario.

Scenario 2C: Sum of Existing, Year 2013 and Generated Traffic Volumes with Proposed Geometrics* and a Proposed Traffic Signal. * See Attached Figures for Intersection Geometrics Based on the capacity analysis results summarized above, the conclusions and recommendations outlined in the original traffic operations analysis remain unchanged for this intersection. The conclusions and recommendations are based on future traffic volumes from Burlingame as well as volumes from vacant land that is to be developed within the surrounding area. The recommendations are as follows: • Shelborne Road should be aligned at 116t'' Street. • Left-turn lanes should be added along all approaches. • A traffic signal should be installed when warranted. - 12- 9-03; 3:03PM;PIttman Partners ~19-~8-U1110t6UAM t t r ;5809786 # 2/ 2 Al ~p020800:1A 5 .-.
