This is a very small fire lane that would be lost without the vertical poles to define the area. The grass is well maintained with no visible markings of difference from surrounding grass. There is a small flush concrete curb between the asphalt and the grass paving.

View of fire lane just after a rain shower. The foreground is a turning lane for car traffic accessing the drive through banking lanes.

Close-up of the grass condition, which is excellent. You can see why vertical markers are a good idea to define the fire lane.
