• Allow exiting traffic to flow back to the east access point through the parking lot. The existing parking lot drive aisle is wide enough for safe two way traffic flow, which would allow exiting traffic the opportunity to exit at the same location where they entered the site. • Exit to the proposed development roadway system and then access CSAH 14 at the new proposed access location. For the latter option, further investigation was completed to determine how the new access would operate with both residential and school traffic volumes. School district staff indicated there are approximately 435 students at the Lino Lakes elementary school. School district staff also indicated that approximately 375 of the students are bussed to school each day. The remaining 60 students are dropped off and picked up by a parent. This results in approximately 60 passenger cars and 10 school busses accessing the site to drop off or pick up students in both the morning and afternoon. The elementary school day starts at 9:15 AM, with bus drop -off occurring between 9:00 and 9:10 AM. The school day ends at 3:30 PM, with the buses departing at 3:40 PM. As noted earlier in this report, the weekday AM peak hour for the surrounding roadway system is 7:00 to 8:00 AM and the PM peak hour is 4:30 to 5:30 PM. Therefore, the vast majority of school traffic occurs at times other than either peak hour. During the AM peak hour, which ends one full hour before students are dropped off, very few school trips would occur. A similar time difference occurs for the PM peak hour. Even if 50 percent of the school traffic exited during the peak hours, which is very unlikely considering the time difference, all movements at the CSAH 14 intersection with the proposed access point operate at the same levels of service as shown in Tables 2 and 3. During both the AM and PM peak hours, the maximum expected queue length is 50 feet on the southbound approach. Therefore, the intersection is expected to operate in an acceptable manner in the 2011 Build condition.
