15 U.S. Communities Set High Tide Flooding Records Due To Sea Level Rise

“Sea level rise flooding of U.S. coastlines is happening now, and it is becoming more frequent each year.” That warning is the opening sentence of a new U.S. National Oceanic and Atmospheric Administration report titled “2019 State of U.S. High Tide Flooding with a 2020 Outlook”.

Agency scientists report that in 2019 fifteen communities, including Miami, Charleston, and Savannah, set records for the number of days that they experienced so-called “sunny day” flooding that isn’t related to rain storms or storm surge. From May through April, East Point, a city near Houston, TX, reported 64 days of high-tide flooding.

According to the report, the situation is going to get much, much worse as sea levels continue to rise in the coming decades. In some cases, it will reach the point that the high tides now bringing “nuisance” flooding will one day be considered the normal high tide.

It’s important to note that NOAA only measures high-tide flooding at 89 sites, so there may be many more communities experiencing regular sea level rise flooding on an increasing basis that aren’t included in the agency’s findings. The experts list New York City, Philadelphia, Baltimore and Washington among the communities that could see 100 days a year of high-tide flooding by 2050.

Of special interest to real estate owners, the report mentions that the bouts of sea level rise-driven flooding are already “damaging to infrastructure and cause other economic impacts (transportation delays, businesses closed, tourism impacts, etc.) in coastal communities”. As we’ve seen, coastal cities and towns are already scrambling to find hundreds of billions of dollars to pay for projects — such as sea walls, pumps and the raising of roads and water and sewer pipes — to deal with sea level rise flooding. With federal funds hard to come by, the burden of paying for the much-needed projects will likely fall on taxpayers. Owners and buyers need to stay informed about this pressing problem to protect their financial futures.

When it Comes to Sea Level Rise Real Estate, Timing is (almost) Everything

When buyers are considering purchasing coastal properties in areas that are forecast to experience sea level rise flooding in years or decades to come, one of the questions they have to ask themselves is: “How long do I expect to enjoy the property?”

This question came to light bluntly when I had lunch today with friends who live on an island in San Francisco Bay. My friends, a husband and wife in their mid-60s, said they weren’t too concerned about sea level rise — though they know it’s coming — because it’s not predicted to actually flood their property for another 50 years. As the wife put it, “We’re pretty sure we’ll be dead by then.”

Actuarial tables say she’s probably right. As long as the current sea level rise forecasts hold, they probably will get to enjoy their property for the remainder of their lives.

Sea level rise vs. life expectancy is an important issue for buyers and owners in coastal areas to consider when they’re pondering their real estate options. Sea level rise forecasts are putting a potential expiration date on many communities along the Atlantic, Pacific and Gulf of Mexico coastlines. Knowing when rising seas will begin to inundate cities and towns is critically important for buyers and sellers. Other factors that have to be considered are how will sea level rise impact carrying costs, such as home maintenance, taxes, flood insurance and condo and homeowners’ association fees.

Combining sea level rise forecasts, your life expectancy, and your ability to afford the carrying costs as you age, is a good way for buyers and owners to tell if it makes sense to get involved or stay involved in real estate in a coastal community. When you’re talking about such fun areas to live in, this level of analysis can sound like a real downer, but not taking this dry-eyed look at the sea level rise situation could lead to an even greater downer: financial disaster.

This issue is discussed in greater detail in “7 Sea Level Rise Real Estate Questions.”

Norfolk Neighborhood Breaks Ground on Sea Level Rise Diversion Project

When confronted by sea level rise flooding, neighborhoods have a choice: Try to hold the waters back, move out of the area, or divert the water into areas designed to accommodate floodwaters.

Virginia Gov. Ralph Northam, Norfolk Mayor Kenneth Alexander and community leaders recently broke ground on a project that takes the last approach to cope with sea level rise flooding. Resilience Park, part of the Ohio Creek Watershed Project, will create a green space to store and absorb floodwater. The project also includes a coastal flood berm, restored tidal creek wetland, and sports and recreational facilities.

A major plus to residents is that that project also includes a walking path that will connect two predominantly African American neighborhoods. “The Ohio Creek Watershed Project is an example of the kind of work we need to do to protect lives, property, and economic opportunity in Hampton roads, and the innovation that will help us build a safer, more sustainable, and resilient Virginia for future generations,” Gov. Northam said.

Virginia is using $112 million of a $120 million U.S. Department of Housing and Urban Development grant to fund the project.

Sea Level Rise Poses Challenges for Commercial Real Estate

Residential real estate isn’t the only sector facing challenges from the threats posed by climate change and sea level rise flooding. Commercial real estate is under pressure, too.

According to a report recently released by Dechert LLP, a global law firm that advises corporations, financial institutions, sovereign states and wealthy individuals, “Climate change is forcing the commercial real estate industry to re-think the effectiveness of flood insurance that developers, lenders and investors have relied on for decades.”

The report notes that extreme weather and sea level rise flooding are pushing the commercial flood insurance system “to a breaking point.” Specifically, the report notes that 14 weather and climate disasters in the United States resulted in $91 billion in damages. Each event had losses exceeding $1 billion mostly from damage to residential and commercial real estate.

Among the challenges faced by the commercial real estate sector discussed in the report:

1) The National Flood Insurance Program (NFIP) administered by Federal Emergency Management Agency is financially unstable. The program is now running over $20 billion in the red, and it relies on government bailouts to continue to operate. Its authority to operate is due for renewal next fall. If it’s not renewed the report says, “The potential for disruption is most concerning for property owners in special flood hazard areas seeking mortgages from federally-backed entities and federally regulated banks because flood insurance is legally required for these loans.”

2) FEMA’s flood maps, which are supposed to identify a commercial property’s exposure to flood risk, are notoriously outdated and they do not consider sea level change or increased flooding estimates. “This has led to costly and catastrophic errors,” the report says. “For example, in 2018, at least 140 Florida homes were demolished following the destruction of Hurricane Michael. However, the relevant FEMA flood map reflected that the properties were in flood zone X (0.2% chance of flood in any year) and flood insurance was not required.”

3. Flood insurance only covers damages, not loss of value. The report says this is a problem because as properties become increasingly vulnerable to flooding, the will inevitably lose value over time. “The worst-case scenario here is particularly bleak,” the report says. “Billions of dollars of real estate will be underwater not only in terms of their market value being less than the outstanding mortgage debt, but also because these properties will be at greater risk of someday being literally underwater. Refinancing these mortgages and insuring these properties will undoubtedly become more challenging each passing year.”

The report goes on to explain how uncertainty in the flood insurance market is leaving the the commercial real estate finance industry without a “uniform strategy to underwrite the increased frequency and severity of flooding due to climate change.” The report says the public and private flood insurance industry “will soon be forced to adjust to face the environmental and economic realities of a country more prone to frequent, catastrophic and repeated flooding.”

The authors predict that the commercial real estate finance industry will evolve to meet the challenges to the marketplace. They identified several issues that need to be monitored: “Among the questions are whether the National Flood Insurance Program will be reformed, whether private flood insurers raise their rates to levels only wealthy real estate sponsors can afford, and whether banks and real estate bond buyers will call for more detailed disclosure to more accurately balance the risk of loss.”

The Dechert LLP report focuses on the commercial real estate industry, but most of its discussions, conclusions and warnings also apply to residential real estate. Buyers, sellers, owners and real estate agents in coastal areas should take the time to read this insightful report to better understand the broader issues that will impact their local real estate markets and property values.

Seizure of Real Estate by Eminent Domain Required in Corps of Engineers’ Draft Proposal for Dealing with Sea Level Rise in the Florida Keys

The Army Corps of Engineers recently presented a draft plan to the Monroe County Commission — which governs the Florida Keys — that would require the county to use eminent domain to force property owners in areas experiencing sea level rise flooding who don’t want to participate in a buyout program to sell their property.

The Corps’ $3 billion plan, intended to help the Keys to deal with sea level rise flooding, includes projects to elevate homes, critical businesses and buildings, like hospitals and fire houses. Where protecting real estate from floodwaters is prohibitively expensive or not technically possible, the Corps is proposing “retreat” — where the properties would be purchased and demolished.

Corps and county officials hope that most property owners would recognize the problem and voluntarily participate in a buyout program. To prevent the creation of neighborhoods with a checkerboard of demolished properties and inhabited homes, the Corps is proposing that the county be required to use eminent domain to force the remaining residents to sell their properties. The concern is that if residents remain in neighborhoods that flood, the government will still have to provide essential services and flood protection, which are the expenses they’re trying to avoid.

Susan Layton, a Corps chief of planning and policy, told the Miami Herald, “We don’t ever go straight to condemnation. We always start with negotiating and coordinating with homeowners and looking for willing sellers.”

Monroe County Officials are nervous about the prospect of eminent domain. County Mayor Heather Carruthers said she’s disturbed by that part of the Corps’ proposal. “I don’t know if we want to have that conversation now, if that’s a nonstarter for us,” she said.

The Corps will seek input from Keys officials and the public before the draft proposal is finalized in September 2021.

Because of their low elevation and exposure to the seawater on all sides, the Keys are at the front lines in the battle against sea level rise. How it adapts to sea level rise flooding will have an enormous impact on planning in the rest of the country. Buyers, sellers, owners and real estate agents in coastal areas should keep informed about what happens there.

California Coastal Commission and Malibu Developer Clash Over Sea Level Rise Height Predictions

The California Coastal Commission, the City of Malibu and coastal developer at clashing over a new beach development on the Pacific Coast Highway. One of the major points of contention is estimates of how much the sea will rise by 2100.

The city approved the developer’s plan based on an old sea level rise estimate of 1.5 feet by the turn of the century. The Coastal Commission takes issue with that prediction, which it says will put the property at a greater risk of flooding.

An engineer the city used to evaluate the project approved the 1.5 foot estimate because that was the number the Coastal Commission included in its 2015 guidance document. The Coastal Commission says the engineer should have used its region-specific estimate and updated 2018 guidance.

The gap between the Coastal Commission and the engineer is enormous. The sea level rise estimate was increased to over five feet in 2018. According to an article in the Malibu Times, a Coastal Commission staff report said, “The difference is more than 4.65 feet, which is significant in determining the required setback, finished floor elevation, and safety of the proposed structure from extreme events and sea level rise.” The report also mentions that scientists are now estimating that the seas could rise anywhere from 3.3 feet to 10 feet by the end of the century.

Scientists are having a tough time predicting sea level rise precisely because humans continue to burn the fossil fuels that create the greenhouse gases that are causing global warming at an accelerated rate. If society continues on this track, even the most liberal predictions could turn out to be conservative, especially if the Greenland and Antarctic ice sheets melt faster and are destabilized to the point where land-based glaciers flow more rapidly into the sea.

The Malibu case is just one example where real estate developers and cities are relying on the most optimistic sea level rise estimates for new construction projects. Buyers shouldn’t trust that a developer or city has done its homework when they purchase a coastal property. Independent due diligence is required to make sure they’re fully informed regarding the risk of sea level rise flooding in the years to come.

California Town Embraces Retreat to Address Sea Level Rise Threat

“Resiliency” and “retreat” are two popular buzzwords regarding sea level rise and real estate. Resiliency is making the changes necessary to prevent sea level rise flooding as long as possible so people can continue to live near the coast. Retreat is recognizing that either the cost is too high or it’s impossible to engineer your way out of the flooding, so everyone has to move back away from the coastline.

Currently, resiliency is the solution most coastal cities and towns are using to address sea level rise. Governments and property owners are spending billions of dollars to elevate property and critical infrastructure, such as pipes and roads. They’re also building and/or raising sea walls and installing pumps.

Retreat is far less popular. From the Florida Keys to the Pacific Coast, property owners are fighting plans that would force them to move away from coastal areas that are subject to sea level rise-driven flooding or at great risk of flooding in the near future.

According to an article in the Los Angeles Times, Marina, California, a small town with 23,000 residents north of Monterey, is actively embracing retreat as a solution to its sea level rise woes. The town is considering plans that have proven unpopular in most coastal locations, including requiring sellers to disclose sea level rise information to buyers, moving infrastructure away from at-risk areas, and discussing relocation with the operators of a private beach resort.

To ensure that the town doesn’t have to make the same difficult decisions over-developed towns are being forced to make regarding resiliency or retreat, Marina officials are actively steering real estate developers toward inland locations away from the eroding shoreline.

David Revell, a coastal scientist and sea level rise consultant, told the Times, “Marina is such a good test case. Here we have the precedent of a community that understands that … there has to be enough lead time to get things out of the way — before it’s in the way.” Revell added that Marina’s pro-active approach “is a really powerful message to the rest of California.”

Residents seem to generally approve of the town’s approach to dealing with sea level rise. The town’s draft plan is almost finished.

Real estate buyers in coastal areas need to consider whether a city or town intends to rely on resiliency or retreat to address sea level rise flooding. Resiliency can lead to higher taxes and the possibility that a property of interest will be impacted by the construction of sea walls, pump stations and other infrastructure. Retreat could limit the amount of time a property can be owned and enjoyed. Both approaches could also impact property value.

Leaked JP Morgan Report Warns Climate Change Could Lead to Human Extinction

“Although precise predictions are not possible, it is clear that the Earth is on an unsustainable trajectory. Something will have to change at some point if the human race is going to survive.”

You might expect to find this doomsday prediction in an op-ed by a rabid environmentalist group. That’s why it’s doubly shocking when you find out it actually appears in a research document leaked from JP Morgan, the world’s largest investor in fossil fuels.

According to a Guardian article, JP Morgan economists David Mackie and Jessica Murray wrote the report, which draws on studies produced at universities and by the International Monetary Fund and UN Government Panel on Climate Change. Rupert Read, an Extinction Rebellion spokesperson obtained a copy, which Guardian journalists were allowed to view.

Mackie and Murray write that policy-makers and financial leaders have to change how climate change is being addressed or there’s a chance that the situation will deteriorate faster than now forecast. They also worry that concern about jobs and competitiveness might prevent humankind from taking the necessary steps to reduce the burning of fossil fuels, which creates the greenhouse gases behind global warming and sea level rise.

JP Morgan’s leaked report is only the latest example of an investment firm stating concern about climate change. Earlier this year the CEO of BlackRock, the world’s largest asset manager, said his firm was moving away from fossil fuels because they’re a poor investment when the world needs to shift to renewables to reduce the release of greenhouse gases.

Buyers, sellers, owners and real estate agents need to take these reports seriously. Their real estate investments are being impacted by climate change and, along the coast, sea level rise flooding. Using the same dry-eyed approach financial institutions are using to evaluate their investments in their real estate decisions is the only way to protect their financial future.

Boston Mounts an Aggressive Plan to Battle Sea Level Rise Flooding

Much of Boston, MA, is built on landfill, which makes it especially vulnerable to sea level rise flooding. With estimates ranging anywhere from 10 inches of global sea level rise to over seven feet by the end of this century, the city is mounting an aggressive plan to hold back the rising seas, according to a Washington Post article.

With over nine inches of sea level rise racked up since the beginning of the last century, areas of Boston are already experiencing sea level rise flooding that’s especially noticeable during extra high king tides in the fall.

To fight back against sea level rise flooding and the higher than normal storm surges it can bring, the Boston’s mayor is dedicating more than $30 million a year to address the problem. Among the projects are elevating streets and parks, and building higher berms and sea walls. City officials are concerned that they’re not doing enough to protect residents and real estate in the poorest neighborhoods, but they are considering options.

Despite the effort to combat sea level rise, Michael Oppenheimer, a professor of geosciences and international affairs at Princeton University, told the Post, Boston and other coastal cities may still ultimately have to retreat from the rising seas. He said, “It is what a lot of cities will have to do because a lot of neighborhoods are not defensible.”

Boston’s experience with sea level rise flooding as discussed in this article is yet another example of why buyers, sellers, owners and real estate agents in coastal areas need to educate themselves on which properties and neighborhoods are experiencing sea level rise flooding and what, if anything, can be done to hold back the rising tides.

Norfolk, VA, Group Hosts Contests to Develop Sea Level Rise Mitigation Programs

As cities and towns along the U.S. coastline scramble to address sea level rise flooding, a non-profit, economic development group in Norfolk, VA, is hosting contests to encourage the private sector to develop ideas.

Norfolk is experiencing some of the fastest sea level rise in the country, and it’s desperate for solutions. The city is using a share of a $120 million grant the State of Virginia received from the federal government to improve its resiliency to flooding.

Among the programs the city supports is an economic incubator called RISE, which is giving seed money to six small businesses that won a contest by submitting innovative proposals to address sea level rise and climate change. The ideas include teaching local business contractors how to elevate houses and establishing oyster reefs to protect the shoreline from storm surge.

This year’s RISE Coastal Community Resilience Challenge includes an invitation for company’s to submit proposals to develop an app that will give drivers real-time flooding information. The group is also looking for proposals to deal with stormwater in parking lots, detect sudden intense rainstorms, and beach sand replenishment.
