Building height

The building height for the water overlay is calculated as follows:

building height = floors * FLOOR_HEIGHT_M

where FLOOR_HEIGHT_M is the height of a single floor, and floors is the number of floors in the section.

Building height in water model

The height of buildings is taken into account when computing the flow of water above ground. Building height is capped at DESIGN_FLOOD_ELEVATION_M; shorter buildings retain their actual height.
