Thank you. You are right. The 80ft buffer is our own buffer not FAA buffer. The message should say so, I will change it.
"Taller than drones may fly" is wrong for 164ft building. What tripped it is, at that spot the local LAANC facility map ceiling which is below 400ft and on top of that, we have kept 50ft clearance over buildings. I would change it so the full calculation is shown.
About the exception for §107.51(b) - I kept the stricter 400 feet AGL cap because of how data is collected. Currently, the building heights are based on OpenStreetMap (some are estimated from floor count from the ground) and Data SF 2010 LiDAR. If the height is wrong or approximated, it may say Go for a flight that is over the legal limit.
I will cite which regulation applies for each route. That is a good idea I will add it.
