Final answer:
Documentation of elevations in flood hazard areas must be submitted before the Foundation inspection, as it is the first critical step in the building construction sequence.
Step-by-step explanation:
If located in a flood hazard area, the documentation of elevations required in Section R322.1.10 shall be submitted to the building official prior to the Foundation inspection. This step is crucial to ensure that the construction process adheres to the necessary safety and regulatory requirements for buildings in areas prone to flooding. The sequence of building construction typically starts from laying down the foundation and progresses systematically towards the top of the structure. It's fundamental to have everything in place before the foundation is inspected, including flood-proofing strategies, as the foundation is the first and most crucial stage of the building process.
