How Concordia Parish floods

Flash flooding driven by severe storms and tropical systems dominates the flood history of Concordia Parish, Louisiana, backed by 29 recorded flash flood events alongside impacts from tropical storms and hurricanes over the last 30 years.

Recent history illustrates these varied threats. In August 2020, Hurricane Delta brought widespread wind damage and heavy rainfall that flooded scattered roads and highways, resulting in 15 homes around Jonesville taking on floodwaters and requiring resident rescues. Months later, an arctic air mass in February 2021 brought freezing rain, heavy icing, sleet, and snow that quickly accumulated and downed numerous trees, large limbs, and power lines.

National Flood Insurance Program records show claims across multiple zones, with the highest concentration occurring in Zone A with 851 claims averaging a $12,150 payout and an average recorded water depth of 10 inches. Zone X recorded 122 claims with an average payout of $18,845 and an average recorded water depth of 12 inches, while Zone X Shaded recorded 169 claims averaging a $5,736 payout with an average recorded water depth of 3 inches. Homeowners and real estate agents in Zone A and Zone X should pay the closest attention to these flood risks, as they account for the vast majority of historical insurance claims in the parish.

Tropical Storm · Aug 30, 2021. Major hurricane Ida made landfall as a strong category four hurricane around 11:55am on August 29 near Grand Isle, LA. It then moved very slowly north through south central Louisiana and into Mississippi on August 30. It then turned northeast and moved across the Jackson metro area as a tropical storm and into northeast Mississippi as a tropical depression through the early morning of August 31. Ida brought tropic…

Flash Flood · Feb 17, 2021. As an arctic air mass continued to build southward across the South on February 17th, another wave of precipitation overspread this cold air mass across northeast Louisiana. The main impacts across this portion of the state were from freezing rain and resulting heavy icing, but some significant accumulations of sleet and snow also occurred. Freezing rain continued through the evening hours. Ice accumulated quickly…

Tropical Storm · Aug 27, 2020. Hurricane Laura made landfall along the Louisiana coast near Lake Charles in the early morning hours of August 27. It moved north into Central Louisiana during the morning and afternoon before turning to the northeast and tracking through Arkansas. Impacts from Laura were felt far from the center of the storm, which was mainly in the form of tropical storm force winds across portions of northeast Louisiana and sou…

Hurricane Delta made landfall along the southwest Louisiana Gulf Coast around 5:00 p.m. CDT on October 9th and moved to the northeast across portions of central and northeast Louisiana. The hurricane produced widespread wind damage and flooding heavy rainfall as it moved inland and weakened. Scattered roads and highways in the region were flooded over or washed out by flash flooding, and 15 homes around Jonesville…

Flood insurance in Concordia Parish

If a building in Concordia Parish is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
