Waterfront Home Values Fall Because of Sea Level Rise, Flooding


November 6, 2018, is fast approaching and voters have the choice between (i) candidates of a political party that denies that climate change is occurring and that is tearing down environmental regulations that seek to slow the climate change process, and (ii) candidates of the opposing party that see climate change among the most pressing problem facing the federal government.  While sadly a number of local "friends" are falling for the racist, xenophobic message of the climate change deniers, those with waterfront properties might want to rethink who they will vote for on election day.  In Hampton Roads the value of waterfront properties is falling or, at best appreciating far more slowly than the values of properties on high ground away from the water.  The phenomenon not only hits homeowners in the pocket books as their typically biggest investment is harmed, but it also erodes city tax bases.  In short, everyone loses in one form or another -  all so Republicans can pander to an ignorance embracing party base.  A piece in the Virginian Pilot looks at the problem which is not confined to Southside cities.   Here are excerpts:
Waterfront homes used to be the safest investment in real estate, but rising tides have turned a sure thing into a potential liability.
After a review of property value data and a litany of studies, The Virginian-Pilot has found mounting evidence that real estate values across Hampton Roads are being driven down as a result of recurrent flooding and sea level rise.
One couple in Norfolk has had their waterfront house, once valued at more than a million dollars, on the market for two years. They’ve dropped the price to less than $800,000 and are still waiting for a buyer.
And it’s not just seven-figure waterfront homes in Norfolk and Virginia Beach taking the hit. Values of seemingly safe houses several blocks from the water are hurting as well.
Several recent studies have shown that impacts from flooding – from water in the basement to inundated streets – already have hamstrung property prices and cost Hampton Roads homeowners hundreds of millions of dollars in lost or unrealized values.  Homeowners might be surprised by these staggering numbers – in many places where research shows flooding is hurting home prices, city assessments show those values rising. They’re just not rising as fast as they could be.
“Part of the idea of getting these numbers out there is that people may not know they’ve lost value, because the actual value may still be going up,” said Jeremy Porter, a Columbia University professor who worked on the recent study with the First Street Foundation, a nonprofit that pushes for solutions to sea level rise by presenting data.
[R]eal estate agents to academics to homeowners agree that recurring flooding and rising seas are driving down the value of what were once considered desirable investments.
A group from First Street and academics from Columbia University developed Flood iQ, a website that allows people to see how the values of waterfront homes have fared since 2006 when compared to similarly valued homes that don’t deal with flooding.
The Washington Post recently highlighted Flood iQ and two other academic studies that came to the same conclusion: Coastal property values aren’t keeping pace. The First Street group studied the values of homes from Virginia to Florida dating back to 2006 and found they’re worth $7.4 billion less than they would be otherwise.
Three-quarters of that loss was due not to flooding homes, but flooding streets, said Steven McAlpine of First Street Foundation.
Our home is on what was once the premier street in Hampton.  After seeing the value drop during the real estate meltdown of a decade ago, the value has stabilized but has not appreciated as one might expect.  Why?  We are located on a tidal creek with 4.6 acres of creek and marsh - the setting is gorgeous but the threat of flooding only too real.

As Coastal Cities Drown, the GOP Denies Reality

Annapolis, Maryland - a scene much like what is commonplace in Norfolk, Virginia
Anyone living in low lying coastal areas of American knows what the GOP refuses to admit: the earth is warming and the sea levels are rising.  In the debate between Mark Warner and GOP challenger Ed Gillespie, who is a climate change denier, Warner suggested that Gillespie visit Norfolk if he wanted to see tangible evidence of what is happening.  Don't expect Gillespie to follow through since the racist/extremist base of the Virginia GOP would be offended.  And for Gillespie, it's all about prostituting himself to those who embrace ignorance and are terrified of modernity.  An article at Climate Central looks at the troubling futures facing a number of American cities.  Here are some highlights:
Coastal American cities are sinking into saturated new realities, new analysis has confirmed. Sea level rise has given a boost to high tides, which are regularly overtopping streets, floorboards and other low-lying areas that had long existed in relatively dehydrated harmony with nearby waterfronts. The trend is projected to worsen sharply in the coming years.

A new report, released by the Union of Concerned Scientists late on Tuesday, forecasts that by 2030, at least 180 floods will strike during high tides every year in Annapolis, Md. In some cases, such flooding will occur twice in a single day, since tides come in and out about two times daily. By 2045, that’s also expected be the case in Washington, D.C., Atlantic City, N.J. and 14 other East Coast and Gulf Coast locations out of 52 analyzed by the Union of Concerned Scientists.

“The shock for us was that tidal flooding could become the new normal in the next 15 years; we didn’t think it would be so soon,” said Melanie Fitzpatrick, one of three researchers at the nonprofit who analyzed tide gauge data and sea level projections, producing soused prognoses for scores of coastal Americans. “If you live on a coast and haven’t seen coastal flooding yet, just give it a few years. You will.”

In the absence of flood-deflecting marshes, seawalls or levees, two-thirds of the 52 communities studied can expect a tripling in the frequency of high-tide flooding during the next 15 years, the researchers concluded. Half of the communities studied are expected to be flooded more than two dozen times every year by 2030.

“Impacts from sea level rise are real and now,” said NOAA oceanographer William Sweet, one of the authors of the agency’s June report. “They’re best viewed in terms of an increase of nuisance flood frequencies. These frequencies have risen dramatically over the last several decades, especially along the East Coast and parts of the Gulf Coast.”
Meanwhile, here in Virginia, the Virginia GOP refuses to use the terms "global warming," "climate change" or "rising sea levels" and will only talk about areas of "repetitive flooding."  That head in the sand approach will cost many in Virginia dearly.

Hampton Roads Snow Day!

Hampton - Chesapeake Avenue covered in ice
Those in other parts of the country with colder climates may laugh at Hampton Roads today which is largely shut down due to on average 4 inches or so of snow.  The real problem is not the amount of snow but instead (i) a near total lack of highway equipment to deal with snow and ice and (ii) the way the temperature dropped rapidly and allowed a layer of ice to form on all the roadways under the layer of snow.  Other than the Interstates and a few main highways, the snow and ice will remain until melting once the weather warms.  With temperatures in the teens and a wind chill of zero, that will not happen today.  The photos give a feel for the winter views.  I will be working from home and logging into the office remotely (I gave my daughter/paralegal the day off).  With so many local drivers being military and from Florida, Southern California and other parts of the South, kamikaze like drivers pose a huge risk even when one knows how to drive in the snow and ice.
