Mr. Lee Elfering, PE Ms. Jessica Jagoe September 10, 2018 Page 4 Question 2 -- Turning Movements and Bus Staging The bus staging diagram indicates 4 buses along the north play area fence and 1 on the west play area fence. Based on the turning movements I don’t think you could get 4 buses to line up on the north side unless they are going to parallel park the west one or two in there, which I doubt. Can you please verify the number that can be staged on the north fence line or explain how they will stack? Response 2 The bus staging diagram submitted in the September 4 Traffic Study has been revised. The revised diagram is shown on Figure A3. As shown on the revised diagram, it is proposed that the nose of the north/south median (adjacent to the fifth bus as it stages along the western side of the school building) will be modified to accommodate the right-turn. It is felt that modifications to the median may not be necessary, but, nonetheless, AFSA is prepared to modify the median if buses have difficulty accomplishing the right-turn and comfortably falling in queue. There are two facts supporting this statement. 1. The turning radii described on Figure A3 are for a 23-WB school bus. The buses used by AFSA have slightly shorter wheel bases; approximately 22 feet – 9 inches. Thus the turning radii shown on Figure A3 are slightly wider than what is actually anticipated. As illustrated, a 23-WB school bus will be able to accomplish the right turn from the west side of the school building and fit behind the fourth bus in queue, after the first bus in queue has departed the site. 2. AFSA staff brought its school buses to the site on Country Drive and tested their ability to accomplish the right-turn from the western side of the school building. They learned that the school buses can accomplish the right-turn without impacting the north/south median and without impacting any of the parking stalls that nose-in against the north property line. As shown on Figure A3, four school buses will queue along the northern edge of the northern fence line in the order in which they arrive, and the fifth bus to arrive will stage along the western side of the school building while it waits for the first bus to arrive to depart the site. Experience at the other two campuses has shown AFSA staff that the order of arrival is predictable, and quite typically Bus # 1 will arrive just ahead of Bus # 2, and Bus # 2 will arrive just ahead of Bus # 3, etc. If there is an unforeseen situation that impacts the arrival of buses, the bus that arrives first will assume the Number 1 position, the bus that arrives second will assume the Number 2 position, etc. Consequently, the school buses will simply wait their turn in queue, and there will be no parallel parking maneuvers. The order in which buses arrive is not a concern for two reasons. First, AFSA staff will be present in the playground to monitor students as they alight and board the buses. Second, all students who are transported by bus will pass through the enclosed playground after alighting and before boarding the buses.
