R322.1.2

Section R322.1.2 is titled 'Structural systems' and covers requirements for flood-resistant construction. The requirement to design and construct buildings and structures to resist movement from flood loads up to a specific level is established. The purpose of this section is to limit damage and loss to buildings and structures due to flooding, which are constructed in areas prone to such.

The model shows an area which floods, causing one house to float, one to collapse, and one to laterally displace which shouldn't happen if built in accordance with this section.
