Mr. Lee Elfering, PE Ms. Jessica Jagoe September 10, 2018 Page 10 because the process is slower than just dropping a student off at the entrance. It would be Planning Staff’s recommendation that if the City Council is considering the PUD Amendment that AFSA be required to submit a Plan B which has the ability to provide additional parking that would be sufficient for up to the maximum enrollment and still maintain an acceptable traffic flow. This Plan B would only need to be implemented if the site layout as proposed results in stacking of vehicles onto Country Drive. By requiring a Plan B ahead of time, the City has done our due diligence to know the site has the ability to still function (both meeting the City and School needs) if modifications with layout need to be made in the future. Without this foresight, we would be reacting to a situation that needs resolve (i.e. stacking traffic, not enough parking) and it may be problematic in trying to create additional parking or revise traffic patterns.” Response to Ms. Jagoe’s Suggestion Trip generation, as shown in Table 1, indicates that during the PM peak hour, which was found to be between 4:15 PM and 5:00 PM, the school will not generate any traffic. Parents picking up their children will arrive and depart between 2:45 and 3:15 PM, a full hour before the PM peak hour begins. Additionally, the first round of five school buses will arrive and depart between 2:30 and 2:48, and the second round of five buses will arrive and depart between 2:55 and 3:05. Finally the 40 faculty and staff will depart the site between 3:30 and 4:00 PM. This has been the experience at the two other AFSA campuses, and there is no reason to suspect that it would be any different at the Little Canada campus. As described in Response 4, it is forecast that at the school’s full build-out a maximum of 22 parents would be expected to occupy parking spaces at the same time in the south side parking lot. Presumably, these parents would have all arrived at the approximate same time. Also discussed in Response 4 is the fact that, at full build-out where there will be 312 students, 42 percent of the students will 7th and 8th graders, whose parents will typically not park when dropping- off and picking-up students. Thus, they won’t contribute to on-site congestion by accomplishing parking maneuvers. As mentioned, the entrance to the south driveway includes an additional 74 feet where vehicles can stack on-site, without spilling onto Country Drive, in the unlikely event there is on-site congestion. Response 5 discusses findings from the intersection capacity analysis, which show that the intersections formed by the two driveways and Country Drive are forecast to operate at LOS A/B during the AM peak hour, with 11 feet on on-site stacking (queuing), LOS A and 7 feet of stacking on Country Drive for northbound vehicles, a northbound left-turn average vehicle delay of 0.8 seconds, and a northbound through movement average vehicle delay of 2.8 seconds. These conditions, which describe very high levels of traffic operations and performance, indicate that the AFSA school use will not negatively impact traffic operations on Country Drive.
