The first is the limiting of the Site Access on <br /> Wayzata Boulevard to right-in/right-out only. Review of tI�e results of the analyses conducted shows that <br /> this limitation will positively impact operations by slightly lessening the PM peak hour westbound c�ueue <br /> at the Wayzata Boulevard/Old Crystal Bay Road intersection and im�roving the northbound LOS at the <br /> Wayzata Boulevard/Site Access intersection fi•om LOS C to B in the PM peak hour. The second change <br /> is the creation of the Old Crystal Bay Road/Noi�th Site Access intersection. Results indicate tliis <br /> � intersection will operate at acceptable levels of service and without adverse queuing issues. <br /> Beyond these two changes, operations for Build conditions are largely similar to those under No-Build <br /> conditions. The differences include two additional move�nents operating at LOS D for the AM peak hour <br /> (the eastUound and tlorthbound through movements; at LOS C for No-Build), and the lengthening of tlle <br /> eastbound AM peak hour 95`�'percentile queue to 467 feet from 394 feet. <br /> Review of Cr�sh D�ta <br /> In order to ensure tl�at addition of site-generated tcaffic would not exacerbate an existing safety problem <br /> at the Wayzata Boulevard site access intersection, crash data for the most recent 4-year period was <br /> requested fi•om MnDOT. Review of the crash data reveals that four ci�ashes occurred within the 4-year <br /> period within 400 feet of the site access. Of ihe foui•craslles, one was a car-deer collision and three were <br /> rear-end collisions. The direction of travel was westbound in 111 four c�ses. The tcaffic signal to the west, <br /> along witl�driver inattention and glare were cited as contributing factors. <br /> Since none of the repocted accidenfis are of the type correctaUle by conversion to right-in/right-out only <br /> access (such as a cight-angle collision), the limitation of the access to right-ii�h•ight-out only movements <br /> does nof appear to be necessaty on the blsis of safety. I-Iowever, as 1 proactive measure to mitigate the <br /> addition of site-generated traffic, such closures have been shown to be Ueneficial ii� similar situations <br /> elsewl�ere. <br /> RLK lnc.
