This parcel is in a VE zone. Elevation 13. For he attached deck is the top of the concrete post technically the lowest structural support? Or is the ground where the post meets the earth the lowest?
C2h is lowest adjacent grade at lowest elevation of deck or stairs, including structural support. So I think you should take the shot at the ground next to the concrete footer supporting the deck. The concrete footer and wooden post are both structural supports.
the enclosure at ground level should be for storage only and must be break away. If it contains a toilet, sink, water heater or any major plumbing fixture the lowest horizontal member is the bottom of the concrete slab.
If the enclosure is for storage only then the lowest horizontal member would be anything that would impede water/debris flow under the elevated portion. To me it looks like the beams on top of the columns just above the double door garage or the beam attached to the three columns in front which ever is lower.
Agree with Lamon... the LSM would be the bottom of the beam that is perpendicular to the joists. How do they do the walls? I'm no structural engineer so I don't make any determination of "break away walls"... that's someone else's area of expertise.
Aren't you guys confusing C2c with C2h? C2c is the bottom of the lowest horizontal structural member. He's asking about C2h, lowest adjacent grade at lowest elevation of deck or stairs. Or am I confused?

It would be the ground shot at the foot of the stairs. The elevation at the foot of the stairs may be higher of lower that the LAG as the LAG is shot at the building corners and the grading will take a down slope away from the building.

Where the concrete meets the earth.
