Roanoke, Louisiana

3 Land Tracts in Jefferson Davis Parish , Mermentau Watershed

Roanoke, Louisiana, located in Jefferson Davis County, faces a relatively moderate risk of natural disasters, with a high risk of river flooding due to its proximity to the Mermentau River. The area's average annual precipitation of 1524.39mm and high humidity of 90% contribute to the heightened flood risk, exacerbated by the flat topography of the Louisiana Coastal region. Additionally, Roanoke is situated in a region prone to hurricanes, further increasing the risk of flooding and wind damage.

Geologically, Roanoke is located near the Calcasieu-Mermentau hydrologic accounting unit, known for its water bodies and wetlands that can overflow during heavy rainfall events. The region's low-lying topography makes it susceptible to inundation, with historical events like Hurricane Rita in 2005 causing significant damage. Despite the relatively low risk of earthquakes and volcanoes, the area's vulnerability to river flooding and hurricanes underscores the importance of disaster preparedness and mitigation efforts.

Overall, Roanoke's risk profile is influenced by its unique blend of climate factors, including high precipitation levels, coastal location, and flat terrain. The area's history of flooding and vulnerability to hurricanes highlight the need for proactive measures to reduce the impact of natural disasters on the community. By understanding and addressing these specific risks, Roanoke can better prepare for and respond to future hazard events.
