Leaving this note open, as we may want to tag this dead-end section of Grayland Ave as foot=yes. Though not explicitly marked as a pedestrian-friendly street (as far as I can tell), it's primary purpose may be to connect foot traffic from the Idylwood Avenue roundabout to the sidewalks on S Harrison Street.

One piece of evidence to support this idea is abundant tactile paving leading from the foot path to the SE directly onto the street ( I should have taken a photo of this when I drove by today)
