Placement is regulated, including distance from food
“Portable sanitation units shall be located as close as practical to the highest concentration of participants, observers and employees of special events. However, the units should be placed as far from the food service area as possible. The safety of users shall be a primary consideration in the placement of the units. At special events, portable sanitation units shall be accessible at all times for maintenance by truck.”

Why it matters: Truck access at all times is the constraint most event layouts break. If a vendor tent or barricade line boxes in the units on Saturday morning, they cannot be serviced Saturday night.
