, drawn to scale from the 2014 survey, the permit plans, the owner's photos, videos and measurements, and a LiDAR scan of the exterior. Line color shows how each element was located.
The roof-deck photo flattened to a true top-down view, north up, using the 24 in pavers as the scale. Yellow lines are edging that could be seen and traced, good to about 6 in. The pink dashed side is hidden under the birches from above; it was placed from a ground-level photo on the assumption that it mirrors the east side, so it is good to about 1 ft.

If a tape agrees with E1 to E4 within a few inches, the visible half is right and only the west side (E6, E8 and E9) needs real numbers.

The house floor levels are from the permit plans. The steps between the upper, intermediate and lower side yards are taped. The lower side yard, rear walkway, driveway and north side yard levels are from the LiDAR scan, good to about 3 in; each falls toward the alley. The rear walkway is taped at 112 in below the first floor. The front yard level is still an estimate.
Each ID is drawn on the plan in orange: a line for a length, a solid square for a height. Send back the ID and what you measured. "Model has" is the current estimate; where it says "scan" the number is from the LiDAR scan and a tape check is still welcome.

All positions are in feet from the northwest lot corner: x runs east, y runs south. The lot's long side bears about 1.4° off true east-west; the drawing squares it up.
