Level 4 consists of 2 areas separated by about 1,600 feet horizontally. I didn’t map connections between the two fourth level areas other than via rooms and passageways on third and fifth level. This is level 4A.

Each Level 4 is 1440’ × 3600’ (5,185,000 square feet) or 119.0 acres.Thats the size of outermost wall ( east-west ) to outermost wall ( north-south ) of this level.

All 64 maps done, uploading on June 1, 2017.

Unless otherwise noted, the corridors are 20 feet high. Many sub-floor corridors have low ceilings. Lower than non-dwarves might be able to deal with easily.

Some areas show deep pits, some with water. These might be connected.
