Hatterasnc - go visit it. We're talking hundreds of feet, not millimeters. Measurement technology is irrelevant. Search National Geographic.
I showed earlier in the thread that "rising sea levels" have had zero impact in the Salvo area. Below is a graphic showing 168 years worth of shoreline measurements in Kill Devil Hills with the latest line being from 2016. The shoreline in this part of KDH has fluctuated a grand total of 160 feet over 168 years. These are actual local measurements as referenced earlier in the thread. Measurements do count, especially these as it pertains to this board.
I am sure that glaciers are shrinking in some places in the world and I am sure that there are places in the world where glaciers are expanding. So what. I can personally do absolutely nothing about that. You are saying with almost certainty that we are fools for purchasing property as they will be underwater soon. You certainly are entitled to your opinion and you can choose not to own property in the Outer Banks. But your opinion that the Outer Banks will be underwater soon is quite ridiculous given that I have shown you two 168 year snippets that contradict your opinion.
There are many other areas from Duck to Hatteras Village that contradict your opinion on how rising sea levels will impact properties in the Outer Banks. I think that you are also forgetting that governments have tools at their disposal such as beach replenishment. The Ocean City, MD/Assateague photo above proves my point as well. Just like Dare County uses beach replenishment, it's obvious that either Ocean City, MD local government or Worcester Co. MD government is heavily involved and invested in keeping their beaches where they are currently.
Just to provide a total picture of the erosion/water levels/accretion situation, search northern tri villages (Rodanthe in particular). Yes, while south of the Rodanthe Pier is relatively stable, points north, not so much.
The populations/tax base/insurance exposure of high density coastal areas determines who gets beach re nourishment and who doesn't and to what extent, if any, the benefactors pay for it. Example, beach re nourishment is a "perpetual" go for the southern peninsula BUT was a one time only (until jug handled bridge is complete) for Mirlo Beach - the insurance exposure/tax base isn't enough to warrant county funded beach re nourishment there.
And, OBX is just a snipet - all up and down the east coast folks are realizing what us waterbilly's have known all our lives - coastal is only temporary. Lest we not forget living/hanging out on the shore is a relatively recent phenomenon - earlier in the last century, folks that lived on the water did so because they couldn't afford to live anywhere else.
What some folks are doing to thwart it is beyond belief - areas on the evaporating eastern shore of Nantucket being a prime example.
Not making a political/judgement call as to the source - just that it's happening. Be it sinking land, accretion, erosion, rising water levels.... whatever, the relative water level is rising. Period. Full Stop.
Oh, and the occasional storm, can change all of that in a heartbeat.
I will focus on the Rodanthe/Waves/Salvo area just for discussion.
Sure, the Mirlo Beach area of Rodanthe has been eroding at a rate of about 14 ft/yr. for a very long time. Not the place to buy a house if you are concerned about erosion. Great place to rent though.
In contrast, areas around Salvo have a beach that is accreting (growing) at a rate of up to 2 ft./yr.
It's simple - if you are concerned about erosion and want to live near the oceanfront, don't buy in the areas with the thick red lines. Buy in areas with green lines or no lines. The graphic below depicts published 2019 erosion rates that are pending adoption.
Funny how there is no mention that any of these areas will be under water anytime soon.
