Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
7 Major Flooding - 7.0 feet above NAVD88 - Major Coastal Flooding. Coastal Flood Warning needed. Extensive inundation of structures and roads in the area is expected. Evacuations of people or transfer of property to higher ground is likely and the advice of Emergency Management should be heeded. Water begins to flood structures in the lower end of the City of Brunswick. Howard Coffin Park flooded. Extensive beach erosion and possible breaches of the dune line, especially in lower areas and beach access areas.
6 Moderate Flooding - 6.0 feet above NAVD88 - Significant Coastal Flooding begins and Coastal Flood Warning needed. Some flooding of structures and roads along the coast and other inland waterways is expected. Evacuation of people or property to higher ground is possible and the advice of Emergency Management or local officials should be heeded. Water in the parking lot near GA-Pacific Plant, in Lanier Blvd and Newcastle St near the Old City Hall. Marshside Grill parking lot flooded and structures threatened.
5.6 Highest Astronomical Tide (HAT) - 5.6 feet above NAVD88 - ESTIMATED!!!
5.5 Minor Flooding - 5.5 feet above NAVD88 - Coastal Flood Advisory is likely and Coastal Flood Warning possible if significant wind and wave action drives water levels higher along the immediate coast. Water comes up through the storm drains into Lanier Blvd and is high in marshes and along the causeways. Flooding of low lying roads and campgrounds possible. Water levels may surge up the dune lines and into beach access areas. Some boat ramps, docks and inland waterways may begin to flood.
5 Action Stage - 5.0 feet above NAVD88 - Coastal Flood Statement Likely and Coastal Flood Advisory is possible if significant wind and wave action drives water levels higher along the immediate coast. Should water levels continue rising, preparations to protect property should begin.
-6.2 Lowest Astronomical Tide (LAT) -6.2 feet below NAVD88 - ESTIMATED!!!
