Flooding can occur during any time of the year. Because the land in Terrebonne Parish is low, much of the property is in a special flood hazard area as determined by the Federal Emergency Management Agency. The principal source of floodwaters in Terrebonne Parish is rain, but in late summer, hurricanes and associated tidal surges also pose a serious threat. Floodwater collects because Terrebonne Parish lies at, or below sea level. The low, flat ground provides little gravity drainage, so water that falls must be pumped out. When the ground is saturated and a heavy rain falls quickly, the system can be overwhelmed and flooding can result.
