Josh Nyquist,Executive Director of Building Operations July 6,2022 PACT Charter School I Traffic Concerns Page 2 commuter/school arrival peak period (7-9 a.m.), p.m. school dismissal peak period (2:00-4:00 p.m.),p.m. commuter peak period (4:00-6:00 p.m.) and Sunday a.m. church peak period (9:30- 11:30 a.m.) at the seven study intersections. b. Due to limited resources in both time and equipment (camera) availability (cameras were committed to other areas before April 13, 2022), cameras were set later Wednesday April 13, 2022 at the study intersections. Therefore, the counts applied in the weekday traffic analysis were the counts collected on Thursday April 14,2022.We have compared these PACT School TIS related Thursday April 14, 2022 counts to previous counts collected for the Trott Brook Crossing EAW at many of the same intersections and find they compare very favorably. From this comparison we conclude the PACT School TIS Thursday April 14, 2022 traffic counts reasonably represent an existing typical study area weekday. c. It is standard traffic engineering practice to apply traffic data collected for a single day to a traffic impact analysis so long as it reasonably represents an existing typical study area weekday or design day. This is particularly true in neighborhoods where the day-to-day traffic patterns are more consistent. If the study area was a commercial area where the day-to-day traffic patterns may be more dynamic, then looking at more than one day and choosing the best day to apply to the traffic impact analysis may be considered. 3. School Bus, Student Drop-Off/Pick-Up and Student Driver site circulation suggestions: a. Move the parent drop-off/pick-up area to the front(south) side of the building.The proposed location of the parent drop-off/pick-up area on the east side of the building and the proposed circulation provides adequate queuing distance to keep traffic from spilling out onto 161 st Avenue. It also separates the school bus drop-off/pick-up from the parent drop-off/pick-up area, always a prime consideration in the configuration of the school site circulation. Moving the parent drop-off/pick-up area to the front (south) side of the building would require moving the school bus drop-off/pick-up to the west side of the building and possibly complicating operations and additional conflict with the student drivers entering/exiting the school site. We believe the school site circulation as proposed is reasonable. 4. Student Drop-off/Pick up concerns regarding spillback onto 161 st Avenue: a. Not all student drop-off/pick-up vehicles are on site at the same time as these vehicles arrive and depart over a period of time. The PM initial queues are more substantial as parents line up to pick-up their children prior to the dismissal time. Based on research conducted by multiple universities of a large sample of schools across the country, the expected onsite PM school pick-up maximum queue length, in vehicles, is approximately five percent of the total enrollment, in students. Assuming the 2028 final phase total enrollment of 790 students, the onsite PM school pick-up maximum queue length is estimated at 40 vehicles. Assuming 25 feet of space per vehicle the length of this onsite maximum queue is estimated at 1,000 feet. Based on the proposed site plan there appears to be well over 1,000 feet of PM school pick- up queuing space available onsite. From this analysis it is concluded that the onsite PM school pick-up maximum queue would be fully contained onsite and not spill out onto 161 st Avenue.
