This applies to all areas of special flood hazard within Terrebonne Parish and the City of Houma.
In order to accomplish its purposes, the ordinance:
Restricts or prohibits uses that are dangerous to health, safety, or property in times of flood, or cause excessive increases in flood heights or velocities; Requires that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; Controls the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwaters; Controls filling, grading, dredging, and other development which may increase flood damage; Prevents or regulates the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards to other lands.
The NFIP requires that a building must meet the same construction requirements as a new building if the cost of reconstruction, rehabilitation addition, or other improvements to a building equals or exceeds 50% of the building's market values.
Substantially damaged buildings are those in which the cost of repairs equals or exceeds 50% of the building's value prior to its being damaged. These buildings must be elevated above the base flood elevation.
