How McIntosh County floods

Tropical storms and coastal flooding dominate the flood risk profile in McIntosh County, supported by NOAA records showing 29 tropical storm events and 9 coastal flood events over the last 30 years.

Recent history underscores this exposure. In September 2024, Tropical Storm Helene impacted the region after making landfall in Florida as a major hurricane. Similarly, Tropical Storm Idalia brought severe impacts in August 2023, and Tropical Depression Elsa tracked through the area in July 2021.

NFIP claim data indicates that properties located in FEMA flood zones A and V experience the most frequent and costly impacts. Zone A accounts for 43 claims with an average payout of $23,651 and an average recorded water depth of 2 inches, while Zone V records 9 claims with an average payout of $50,008 and an average water depth of 2 inches. Consequently, coastal property owners and residents in designated high-risk flood zones should pay the closest attention to local flood hazards and insurance requirements.

Where the flood claims came from

10% of McIntosh County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

Tropical Storm · Sep 26, 2024. Helene first developed into a tropical storm in the northwest Caribbean Sea in the late morning of September 24, and strengthened into a hurricane near the Yucatan peninsula about 24 hours later. Helene continued to strengthen and became a major hurricane as it moved to the north-northeast across the eastern Gulf of Mexico. Helene made landfall in the Big Bend region of Florida in the late evening hours of Septemb…

Tropical Storm · Aug 30, 2023. Idalia first developed into a tropical depression across the western Caribbean Sea near the Yucatan Peninsula on August 26th before slowly gaining strength and becoming a tropical storm on August 27th. The storm then began to take a northward track the next day, passing the western tip of Cuba while gaining strength. On August 29th, Idalia was upgraded to a Category 1 hurricane early in the morning, then intensifi…

Tropical Depression · Jul 7, 2021. Elsa initially developed as a Tropical Depression over the central tropical Atlantic late in the evening of June 30th, 2021. The system quickly tracked to the west-northwest and became Tropical Storm Elsa on the morning of July 1st, 2021 about 850 miles east-southeast of the Windward Islands.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. 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.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  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 McIntosh County

If a building in McIntosh County 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.
