What is the capacity to plan against?
The venue's football capacity is about 69,000, and up to about 72,000 for special events, according to Wikipedia.
The plan is set for the event's expected attendance, which can be far below the capacity for a midweek match or far above it for a concert.
The concert record of 77,286 and the soccer figure of about 37,722 show how widely the crowds vary.
Why are the approaches the planning question?
The venue's facilities serve the people inside, and the crowd outside waits on the approaches for hours before the gates open.
A pre-game crowd on the sidewalks and the transit approach needs units within reach, and the approach is where the waiting happens.
The approach plan follows the flow of the crowd from the transit and the car park to the gates.
Who gives the permission?
The City's office governs the public way for a unit on a street, and the owner of a private lot gives the consent for a unit on that lot.
The venue's operators and the City's event office are both consulted for the approaches, so the placement is agreed with each.
The consent or permit for each unit is kept with the plan.
How is the count set for a game?
The operator sets the count per cluster from the expected crowd at each approach, the time the crowd spends there and whether food or drink is sold on the way.
No City ratio for game-day restrooms is published in the sources for this page, so the figure is worked out for each approach and recorded.
The count reflects the approach, not the venue, and servicing is timed for the hour before the gates and the hour after the game.
How are the crowds at the transit stops handled?
The transit stops carry the arrival and departure waves, and the clusters at the stops are sized for the peak train or bus, with a visit timed before each rush.
A transit stop with no unit in reach sends the crowd onto the street, which is a hazard on game nights. The cluster sits at the stop's edge, clear of the crossing.
The provider and the transit contact agree the timing of the visits so the crews do not block the stops.
What is the plan for the car parks and the tailgates?
The car park clusters sit on the lot with the owner's consent and a clear route, and the tailgating crowd is given its own cluster away from the parking lanes.
A tailgate crowd that waits for hours needs a cluster in reach, and the plan places it at the lot's edge.
The owner's consent covers the lot's use, and the arrangement is written into the file.
