The zones you’ll see on the map

Cross-section of a coastal flood zoneDiagram: land rising away from the shore. The 1%-annual-chance flood surface reaches inland; where storm waves ride on top of it the zone is V or VE, behind that AE, then a band of shaded X, then X on higher ground.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXX shadedAEVE
  1. VE / V Storm waves of 3 feet or more ride on top of the flood. Strictest building rules; homes go up on pilings.
  2. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Marrero CDP

If a building 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.

The average NFIP premium across Louisiana was $1,052 a year on August 31, 2026 (premium plus the federal policy fee; the reserve fund assessment and HFIAA surcharge come on top). Risk Rating 2.0 prices each building on its own flood risk, so a quote can be far from the average.

Outside the high-risk 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. Quotes: FloodSmart.gov or a local agent.
