Caddo Parish, Louisiana Flood Zone Map

How Caddo Parish floods

Flash flooding from heavy rainfall events dominates the flood risk profile of Caddo Parish, accounting for 246 events and two deaths over the last 30 years, alongside 31 general floods, three tropical storms, and one hurricane. Recent historical events illustrate this pattern, including saturated grounds and heavy rainfall along a quasi-stationary boundary in February 2025, a mature squall line with embedded mesovortices in March 2025, and scattered severe thunderstorms driven by an upper-level trough in May 2025.

National Flood Insurance Program claims data demonstrate that flood impacts extend across multiple zones. Zone A bears the heaviest concentration of risk with 1,763 claims averaging $23,107 and an average recorded water depth of 6 inches. However, properties outside designated high-risk areas also experience significant water intrusion; Zone X recorded 351 claims averaging $24,571 with an average water depth of 11 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located in Zone A due to the sheer volume of historical claims, as well as properties in Zone X where average recorded flood depths reach 11 inches per claim.

From the storm reports

Flash Flood · Apr 30, 2025. A weak cold front slowly advanced southeast into portions of Northeast Texas, Southeast Oklahoma, into Western Arkansas and Southern Missouri on April 30th, and focused a warm, very moist, and unstable air mass in place across much of East Texas, North Louisiana, and Southwest Arkansas during the afternoon through the evening hours. Meanwhile, an upper low pressure area ejected northeast from the Desert Southwest…

Flash Flood · Aug 29, 2025. Significant banding of heavy showers and thunderstorms with cell-training occurred on the morning of August 29th across East Texas and North Louisiana, posing the threat of flash flooding. A gradual increase in warm air advection and isentropic ascent was noted on the north side of a quasi-stationary frontal boundary and within a very moist and moderately unstable air mass. MUCAPE values ranged from 1000 to 2000 J…

Flash Flood · May 26, 2025. A weak surface frontal boundary drifted south to near the I-20 corridor of East Texas and North Louisiana during the early morning hours of May 26th, with a warm and moist air mass along and south of the front yielding adequate instability along and south of the front. While scattered strong to severe thunderstorms over portions of extreme Northeast Texas, Southeast Oklahoma, and Southwest Arkansas reinforced this…

Flash Flood · Sep 24, 2025. A cool front entered the region during the early afternoon hours of September 24th, ahead of an approaching upper trough that traversed the Southern Plains. Strong heating ahead of the front and attendant trough contributed to increased instability, with large scale forcing from these surface and upper level features contributing to scattered strong to severe thunderstorms containing heavy rainfall across portions…

Flood insurance in Caddo Parish

If a building in Caddo 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.
