Hey there Brent, hope all is well on the other side of the world. I am not following how the centerline shown is actually the centerline of the public way. There appears to be a landing and stair in the public way. The definition of public way requires it to be 10ft min in width and the stairs intrude into this space. Also, it appears the public way is on the stage property unless there is an additional PL not shown. If the PL shown on the plans is the only one then it would appear the public way is an egress easement and thus I think the stage property could measure to the PL as shown. I believe the 3-story could measure to the centerline as the Code allows but I am not convinced what is shown is actually the centerline.
Also I noticed that the edge of the public way appears to be the edge of the stage structure and I cannot tell whether the overhang is greater than 10ft from the ground
