Explanation:

Floodplain regulation is done to reduce flood damage and risk. This program regulated by setting minimum standards for development in floodplain. This limits the undue development along protected or designated floodplains.

It demarcates floodplain zoning areas and does not allow any development in such areas. The regulations instruct structural limitations like base flood elevation or the lowest floor elevation of buildings or other structures.

The main idea is to limit damage or risk caused by flood by constructing flood-safe buildings.
