King Tide Season is here. Are you Prepared?

King Tide flooding has returned in Florida and will continue until early November. King Tide is the highest predicted tide of the year at given coastal locations. They can lead to what NOAA describes as “nuisance” flooding, causing road closures, overwhelming storm drains and damaging property. 

There were only 4 recorded days of King Tide flooding in Miami in 1963.  By 2016, that had grown to an average of 15 days per year, and the increase has been steady. In fact, King Tide has increased by 400% according to estimates by the University of Miami. King Tide events are not unique to Florida. In Annapolis MD, it has grown from 4 days to 40 days in the same period, and in San Francisco CA, from 2 days to 10 days.

Luckily, there are certain adaptive measures that can be taken to prevent or minimize potential damage from a King Tide event. Last week, Coastal Risk team members went out to Virginia Key during King Tide to analyze the amount of flooding and compare it to its 2016 analysis. The results confirmed our predictions. 

Last year, a Coastal Risk representative, led a group of citizen scientists to study Michigan Ave and 11th Street in Miami Beach. The group collected and analyzed multiple water samples for height and salinity every 15 minutes.

What they found was surprising.

Despite historical records of flooding in the area, the group did not find any major impacts.

This is because prior to the King Tide, the City of Miami Beach implemented a series of portable water pumps to prepare for the flooding event—a small adaptive measure that saved hundreds of thousands of dollars in property damage. 

Measures like this are what can help coastal communities become resilient and sustainable in a future with higher sea levels. Areas that did not have pumps were also measured and turned out to be not as lucky. 

Fortunately, King Tide flooding is seasonal, predictable, and preventive measures can be taken to avoid damage from these events. The first step would be to know your property’s Flood Score.  

With Coastal Risk’s Flood Risk Reports, you can find out exactly how many days your property can expect to flood.  

This can be critical to preventing business losses and protect market values.

Coastal Risk’s Flood Risk Reports visually represent the total number of tidal flooding days over a 30-year measure. It is projected using modeling based on the US Army Corps of Engineers (USACE) high sea level rise projection (footnote) and other local factors. Below, you will find a sample First Score that visually represents flooding along the Rickenbacker Causeway in Miami. 

 

The Report is broken down into six 5-year increments. Each increment indicates the number of tidal flood days the property will experience during that time period. For example, over the years 2036 to 2040 there will be 566 days of tidal flooding.

At Coastal Risk, our vision is that coastal cities will build tools and bolster infrastructure that is more resilient in the face of storm surge, flooding events, sea-level rise or King Tide.
