The New, Improved “7 Sea Level Rise Real Estate Questions for Buyers, Sellers, Owners & Real Estate Agents” is Finally Here!

It took some doing, but the paperback version of the 2021 Edition of “7 Sea Level Rise Real Estate Questions for Buyers, Sellers, Owners & Real Estate Agents” is now available on Amazon.com! The Kindle e-reader version is in Amazon’s review process.

The hardest part of writing this year’s edition was forcing myself to stop as new information about global warming and sea level rise kept streaming in. The new book is much more comprehensive than the first edition. It has special chapters that cover developments in the field since the 2020 edition and a detailed description of what happens when sea level rise floodwater streams into a community, neighborhood, and individual property. It also has more information and instructions on how buyers, sellers, owners and real estate agents can protect their financial future by performing due diligence — gathering information from more than one source — before they make a critical real estate decision in a coastal city experiencing or soon to experience sea level rise flooding.

The challenge to anyone involved in real estate along the Atlantic, Pacific and Gulf of Mexico coastlines remains unchanged: There is no single source of reliable information that will give them the facts they need to know about past, present, and future sea level rise flooding. So they have to put on their detectives’ hats and find it themselves. “7 Sea Level Rise Real Estate Questions for Buyers, Sellers, Owners & Real Estate Agents” will give them the tools and insight they need to gather the information they need to make informed decisions.

Please check back often. I’ll have a lot more to say about the book, and, now that Covid-19 appears to be calming down, I’ll post a lot more updates with the latest developments regarding sea level rise and real estate.

2021 Edition of “7 Sea Level Rise Real Estate Questions for Buyers, Sellers, Owners & Real Estate Agents” Coming Soon!

Sorry I haven’t updated the site lately, but I’ve actually been busy writing the 2021 edition of “7 Sea Level Rise Real Estate Questions for Buyers, Sellers, Owners & Real Estate Agents.”

Managing the threat of Covid-19 threw me off my intended schedule, which was to release the book in November or December of 2020, but I’m back on track to bring you a comprehensive look at the risks involved in purchasing real estate in coastal communities that are currently experiencing sea level rise flooding or will have to confront the challenge in the years and decades to come. The new edition includes the latest developments regarding sea level rise science and the approach federal, state, and local governments are taking to address the flooding. It also has chapters that describe in detail how sea level rise flooding impacts communities, neighborhoods and specific properties, and what buyers, sellers, owners, and real estate agents need to do about it.

Those of you who purchased the 2020 edition of “7 Sea Level Rise Real Estate Questions” on Amazon.com will find a lot of new information presented clearly and concisely. The book will be of special value to buyers, sellers, owners, and real estate agents operating in coastal areas who want to make informed decisions regarding real estate transactions in areas confronting this creeping threat.

I will update the site when the book is available in paperback or Kindle versions, which should be in about two weeks. Thank you for your patience.

Once the book is released, I will get back on track to updating this site on a regular basis with the latest reports regarding sea level rise flooding and real estate.

Are Miami Area Real Estate Owners Ready for 13-Foot Tall Walls to Control Storm Surge?

How do you protect nearly 3 million residents and $311 billion worth of real estate in and around Miami from more intense storm surges driven by climate change and rising seas? That’s the challenge taken on by the U.S. Army Corps of Engineers, and the solution its proposing could have a massive impact on real estate owners.

According to a report in the Miami Herald, the Corps has drafted a proposal that includes 10-to-13-foot high walls, moveable storm surge barriers for canal and river openings, along with the elevation of 10,000 homes and floodproofing of 7,000 buildings. The proposal, due to be formally released this spring, carries an $8 billion price tag, 65% of which would be federally funded. Local governments would pick up the rest of the cost.

Included in the proposal is the purchase of 350 properties through eminent domain to make room for the walls. If the plan is approved, the Corps aims to start construction on the massive project by 2026.

The Corps’ plans could have a major impact on the real estate market in Miami and Miami-Dade County. Some property owners could face the prospect of losing their real estate to eminent domain. Those who remain could see a spike in their property taxes and a loss in property value due to the higher taxes and proximity to flood-control structures. For example, properties that lose their water views to concrete walls could witness a drop in value.

Clearly something has to be done to reduce the threat posed by storm surge driven by climate change and rising seas. To protect their real estate investment and financial futures, buyers, sellers, owners and real estate agents need to get involved when the final details are being hammered out over the next year.

One point to keep in mind is that the Corps’ plan only addresses storm surge, not sea level rise itself. Because South Florida is built on porous rock, seawater can seep under walls.

Another important point that needs to be considered is that Miami and Miami-Dade County aren’t the only coastal real estate markets facing upheaval due to climate change and sea level rise flooding. Cities and towns all along the Atlantic, Pacific and Gulf of Mexico coastlines are struggling to draft effective plans to combat rising waters. Coming up with the billions of dollars needed to fund their projects is a whole other problem.

Twitter Helps Researchers Identify Localized Sea Level Rise Flooding

When it comes to identifying localized sea level rise flooding, tidal gauges aren’t necessarily giving the full picture.

Climate researchers published a study this week in the journal Nature Communications that concluded Twitter may provide a more accurate read on what’s actually going on on the ground. Why? For one thing, there are only 132 tidal gauge stations covering over 3,700 miles of the U.S. Gulf of Mexico and Atlantic coastlines. That leaves enormous gaps between the measuring locations.

As a result, the same high tide that causes little or no flooding in a location with a gauge could cause damaging flooding in another location with a different elevation or concentration of people and structures. The study says, “The same degree of inundation could have substantially different social impacts, depending on the distribution of people, infrastructure and economic activity along the coast.”

To get a clearer picture of how the flooding is impacting coastal locations, the researchers studied nearly half a million tweets sent by 5 million Twitter users in about 235 counties. What they found was that nuisance flooding was occurring in many locations that was not detected by tide gauges.

Most of the undetected nuisance flooding occurred in 22 counties, including those that encompass Miami, New York and Boston, with over 13 million people.

Having a clear picture of what’s happening everywhere is critical to drawing up plans to address the sea level rise flooding as the ocean level rises. “Understanding where coastal floods happen, identifying which meteorological and tide conditions produce floods, and grasping the consequences for flood-affected communities and infrastructure is critical for coastal flood preparation and response,” the study said.

Study co-authors, Frances C. Moore, of the Department of Environmental Science and Policy at the University of California, Davis, and Nick Obradovich, of the Max Plank Institute of Human Development in Berlin, Germany, caution that one major limit of their study is that once people get used to the nuisance flooding they become less likely to report it on social media.

The fact that even tidal gauges can’t always be relied on to give the complete picture of sea level rise flooding in a given area is all the more reason that buyers, sellers, owners and real estate agents need to rely on more than one source when considering the flood risk for a given piece of property.

New Report Names Miami the “Most Vulnerable” City in the World for Sea Level Rise Flooding

A new report by Resources for the Future (RFF), a nonpartisan think tank, concludes that Miami will soon become “the most vulnerable major coastal city in the world” for sea level rise flooding, storm surges and other impacts of climate change. The experts based their conclusion on the fact that Miami has billions of dollars worth of real estate and other assets that will be put increasingly at-risk as the seas continue to rise between now 2040.

The RFF published a graphic-rich report titled “Understanding Sea Level Rise in Florida, 2040” last week that illustrates the challenges faced by Miami and the entire state of Florida. The report was created using data collected by the Climate Impact Lab, a group of scientists, economists and other experts who are trying to quantify the impact climate change will have on the world economy in real numbers.

In a press release, the RFF listed the following potential impacts on Florida if the world doesn’t reduce the greenhouse gas emissions that are driving global warming and sea level rise flooding:

  • Severe “100-year floods” will potentially occur once every few years rather than once a century, endangering about 300,000 homes, 2,500 miles of roadways, 30 schools, and four hospitals statewide.
  • Rising seas also threaten the 490,000 Floridians who live on land less than 3 feet above the high-water mark, and coastal properties worth an estimated $145 billion in property value. The counties with the largest number of people facing these risks are Miami-Dade, Broward, Pinellas, Monroe, and Hillsborough.
  • In some areas—the Keys in particular—it is unlikely that communities will be able to meet the costs of raising all public roadways to accommodate higher sea levels by 2045, suggesting that some roads and neighborhoods will need to be abandoned.
  • Miami has over $400 billion in assets put at risk by coastal flooding and storms—the largest amount of any major coastal city in the world.
  • Extreme temperatures and other impacts will seriously affect public health. In a moderate emissions scenario, the rate of mortality is projected to increase by 3.8 deaths per 100,000 Florida residents per year—that’s roughly 1,000 additional deaths annually by 2035.
  • Federal carbon pricing policies, which would reduce these risks, are projected to cost less than $1,000 annually for Florida households earning under $99,000 per year, with costs for higher earners reaching as high as $5,000 annually.

The study’s co-authors said: “Addressing climate change has up-front costs. But failing to address climate change? Those costs are likely to be much greater and long lasting.”

The RFF research was funded by the VoLo Foundation, a private family foundation established to educate the public to create a sustainable and secure planet for generations to come. 

This report further reinforces the fact that buyers, sellers, owners and real estate agents in coastal areas need to be aware of sea level rise and its impact on a property of interest, neighborhood and community to make informed decisions that will protect their financial futures.

Do Real Estate Sellers Have to Disclose Sea Level Rise Flooding to Buyers?

Question: When real estate owners sell property that’s experiencing sea level rise flooding or there’s flooding in the street out front, are they required to inform buyers of the problem in the sellers’ disclosure? Answer: It depends on state they reside in.

Real estate sellers’ disclosures are not governed by federal laws. Instead, each state decides what sellers have to disclose, and the laws vary greatly from state to state. Texas, for example, is quite strict in requiring sellers to disclose flooding in great detail. Virginia, on the other hand, is basically a let the buyer beware state when it comes to sellers’ disclosures.

The Natural Resources Defense Council surveyed the state disclosure laws and created a map that grades state’s on the stringency of their sellers’ disclosure requirements. Sellers need to know what’s required in their state to avoid the potential of costly lawsuits. To ensure they’re in compliance, sellers may need to confer with an attorney.

This video discusses how sea level rise flooding complicates the sellers’ disclosure process. “7 Sea Level Rise Real Estate Questions — for Buyers, Sellers, Owners & Real Estate Agents” explores the issue in greater detail.
