Peak Hour Levels of Service As indicated in Table 2 and Table 3, adequate level of service will be provided at all intersections with the exception of the CSAH 14 /CSAH 23 intersection. The CSAH 14 /CSAH 23 intersection is approaching capacity under existing PM traffic volumes and is expected to experience level of service problems (i.e. excessive delay) during the PM peak period under the 2011 No -Build volumes. This difficulty will increase with 2011 Build volumes. During the AM peak period, this intersection is expected to approach capacity under 2011 No- Build volumes, and experience level of service problems under 2011 Build volumes. As part of this analysis, the peak hour traffic signal warrant requirements were reviewed for the study scenarios. Based on the un- factored warrant requirements, 2006 Existing, 2011 No- Build, and 2011 Build scenarios satisfy the peak hour volume warrant for the AM and PM peak hours. With a signal in- place, this intersection will function at LOS C or better. Traffic Operations Impacts for Lino Lakes Elementary School The school has two existing full movement access points on CSAH 14. The western access is signed for exiting movements only while the eastern access is used for both entering and exiting movements. The site is currently signed for east to west flow through the drop -off lane and the parking lot. As shown in Figure 6, the recommended access plan includes closure of the western access and the construction of a connection road to the proposed development roadway system. Under this plan, all school traffic would still enter at the east access point. Two options for exiting traffic are: 4 -6 Northbound Southbound Eastbound Westbound CR 23 /CR 14 LT TH RT LT TH RT LT TH RT LT TH RT 2006 E E B C C B C C B D D B 2011 no build F F C C C C E E B F F B 2011 build F F C D D C F F B F F B 2011 build signal control D D A B B A D D A C C A CR 23/Pine St LT TH RT LT TH RT LT TH RT LT TH RT 2006 A A - - A A B - B - - - 2011 no build A A - - A A B - B - - - 2011 build A A - - A A B - B - - - CR 14/4`h Ave LT TH RT LT TH RT LT TH RT LT TH RT 2006 C C C C C C A A A A A A 2011 no build D D D C C C A A A A A A 2011 build D D D C C C A A A A A A Pine St/access LT TH RT LT TH RT LT TH RT LT TH RT 2011 build A - A - - - - A A A A - CR 14 /access LT TH RT LT TH RT LT TH RT LT TH RT 2011 build - - - D - D A A - - A A As indicated in Table 2 and Table 3, adequate level of service will be provided at all intersections with the exception of the CSAH 14 /CSAH 23 intersection.
