Overhead view of Potrero
Fire Trucks on Potrero entering an exiting General Hospital Parking lot near 21st Street.
Overhead view of maneuvers overlaid on new Potrero Plan, (not to scale yet). As you can see, there is a small island in the middle of Potrero near 21st Street now. The first engine used the opposite side of the street to pull around the island and make a left turn into the hospital lot.
The larger truck pulled out and slowly made the turn into the lot, while waiting for the cars to stop. This would not be possible with an island and trees south of 21st street.
To exit the lot, the large truck had a couple of firemen directing traffic while it backed out into the road, using at least three of the lanes. This would not work with trees in the middle of the road.
