Attachment D <br />Review of Twin Lakes Station EAWJanuary 17, 2022 <br /> Page 2 <br /> <br /> <br />Existing Intersection Capacity Analysis <br />6.Traffic analysis was completed for the a.m. and p.m. peak hours. This is appropriate for the given <br />land uses. <br />7.The delays and queues identified in the analysis results are provided from a HCM report and <br />appear to be accurate. <br />Alternative Traffic Control <br />8.The justification for installation of a signal at Herschel is adequate. <br />Full Build Intersection Capacity Analysis <br />9.The report states that the Fairview Avenue intersection is LOS E in Opening Year analysis, but <br />this not reflected in the table or HCM report. They may have meant to say Snelling Avenue. <br />10.The delays and queues identified in the analysis results are provided from a HCM report and <br />appear to be accurate. <br />Conclusion and Site Review <br />11.A site plan review was not completed at part of the study to identify any changes with the site <br />plan. <br />12.The site plan shows the bank having approximately 290 feet of queueing space. A study by Spack <br />Consulting, using empirical data, shows that the average maximum queue for banks is 6 vehicles <br />(120 feet), and the 85th percentile queue is 8 vehicles (160 feet). The proposed driveway for the <br />bank should provide sufficient space for queueing. <br />13.The site plan shows the car wash having approximately 480 feet of queueing space. A study by <br />Spack Consulting, using empirical data, shows that the average maximum queue for car washes is <br />5 vehicles (100 feet), and the 85th percentile queue is 6 vehicles (120 feet). The proposed driveway <br />for the car wash should provide sufficient space for queueing. <br />14.The site plan shows the restaurant having approximately 220 feet of queueing space. A study by <br />Spack Consulting, using empirical data, shows that the average maximum queue for fast food <br />restaurants is 8.5 vehicles (170 feet), and the 85th percentile queue is 12 vehicles (240 feet). The <br />proposed driveway for the restaurant should provide sufficient space for queueing at most times, <br />but at its absolute peaks, queues may spillover into the parking area. <br /> <br /> <br />
