<br />Memorandum to Dennis Trooien, Dennis Properties <br />Subject: Traffic and Parking Stndy for Proposed Redevelopment of Arden Plaza <br />Page 6 of 15 <br />September 17, 2007 <br /> <br />directional distribution percentages, which are based on the existing traffic patterns for <br />Arden Plaza: <br /> <br />. 30 percent to/from the north on Lexington A venue <br />. 30 percent to/from the south on Lexington A venue <br />. 25 percent to/from the west on County Road E <br />. 15 percent to/from the east on County Road E <br /> <br />Development volumes were then added to the 2009 no-bnild volumes to arrive at 2009 <br />build volumes. Figure] shows traffic volumes for the two driveway intersections for the <br />following scenarios: existing (2007), 2007 with full occupancy of existing uses, 2009 no- <br />build, and 2009 build. <br /> <br />4) Traffic Analyses. Capacity analyses were completed at the subject intersections for all <br />four of the above scenarios using the Synchro 7 analysis software. Existing geometrics <br />and traffic control were used in the analysis for all three scenarios. The driveway <br />intersection on County Road E presently provides one left turn lane, one through lane, <br />and one shared through/right turn lane on the east and west approaches. The north <br />approach provides one lane for all movements. The south approach provides one shared <br />through/left turn lane, and a short right turn lane, which provides an effective storage <br />length of about 50 feet. The driveway intersection on Lexington A venue is aT <br />intersection that presently provides one through lane and one shared through/right turn <br />lane on the north approach and one through lane and one left turn lane on the south <br />approach. The west approach, which serves the Arden Plaza development, provides one <br />left turn lane and a short right turn lane, which is about 50 feet long. The County Road <br />E/Lexington A venue intersection is controlled by a traffic signal and provides one left <br />turn lane, one through lane, and one shared through/right turn lane on all four approaches. <br /> <br />Capacity analysis results are presented in terms of level of service (LOS), which ranges <br />from A to F. LOS A represents the best intersection operation, with very little delay for <br />each vehicle using the intersection. LOS F represents the worst intersection operation <br />with excessive delay. LOS results for the subject intersections are presented in Figure 3 <br />and are discussed in detail next. Synchro worksheets showing delay values and other key <br />outputs are presented in the appendix. <br /> <br />. County Road E/Lexington Avenue. As presented in Figure 3, this intersection <br />presently operates at LOS E and will operate at LOS Fin 2009 without the <br />proposed development. The proposed development will increase the overall <br />intersection volume by only 2.7 percent and the overall delay for the intersection <br />by only about 12 seconds. The LOS F operation at this intersection will occur <br />regardless of the proposed development. Based on further analyses, we <br />determined that LOS D or better could be provided at the subject intersection for <br />
