Hurricane Ian Exposing Real Estate Prone to Sea Level Rise Flooding

As Hurricane Ian churns toward Florida today, it’s sending rain bands into the southern half of the peninsula. Driving in South Florida where I live, I saw several streets and intersections near the Intracoastal Waterway that don’t normally flood during heavy rainstorms filled with a foot or more of water. Real estate was also being impacted. While the rain is certainly contributing to the flooding, the real culprit is king tides — extra high tides due to the alignment of the sun and moon — combined with sea level rise.

Unfortunately, the storm is striking at the height of a week of higher than normal tides that peaks on Thursday. If today is any indication, the flooding is going to not only flood roads, it’s going to flood yards and homes in the days to come.

Each neighborhood I visited was flooding because of saltwater topping seawalls, emerging out of storm grates, or because pump systems couldn’t keep up. Sadly, I also saw some residents awestruck that their neighborhoods were flooding, even though some of them have been flooding for years. My best guess is that they purchased the properties without being aware of the flooding risk.

Another point to ponder is that many people who bought a property that itself isn’t flooding are discovering that owning real estate that you can’t reach because of sea level rise flooding is a major management issue and a pain in the neck. It’s also disconcerting because unless the flooding is prevented — through the use of elevated seawalls, elevated roads or pumps — sea level rise will eventually cause the flooding to swamp yards and homes.

What I witnessed today in my town is certainly occurring in many other coastal communities this week. It’s a powerful reminder that owners in coastal communities need to start considering sea level rise in their plans, and buyers need to perform due diligence to make sure that their property of interest, streets and neighborhood aren’t currently flooding or likely to flood in the future hurricane or no hurricane.

Video: King Tide Season: The Sea Level Rise Stress-Test

King tide season returned to coastal communities this week, and with it came the king tide/sea level rise flooding that periodically inundates roads, real estate and whole neighborhoods. This video, produced for SeaLevelRiseRealEstate.com, features a discussion of the many ways the king tide months — roughly from September-January — provide the perfect stress-test to give real estate buyers, sellers, owners and agents a sense of how well their communities are battling against sea level rise flooding. It also gives them a read on the level of risk sea level rise flooding poses to their property of interest.

As ice sheets in Greenland and Antarctica continue to melt and the ocean heats and expands due to global warming, sea levels are gradually rising. Add the many inches of sea level rise accumulated over the last hundred years or so to the ancient king tides — higher than normal tides due to the unique alignment of the sun and moon in the fall — and you have a recipe for disaster.

Coastal communities all over the world face a greater threat of flooding during this period In the U.S. this can lead to an enormous amount of property damage as well as damage to roads, water pipes, sewer pipes and other critical infrastructure. The end result is that property owners in affected areas can face higher carrying costs, including expensive repairs, insurance premiums, and taxes as communities implement plans to stave off the flood waters.

During the king tide period, buyers, sellers, owners and real estate agents need to take the time to see what’s actually happening in their communities, find out how much worse it could get, study what their local government intends to do to mitigate the flooding, and reach a dry-eyed understanding of how this will impact their carrying costs and property value. This information will help them to make informed decisions regarding real estate transaction.
