High Water Table, Wetlands Causing Flooding At Cape Hatteras National Seashore

Share

High water tables are being blamed by Cape Hatteras National Seashore officials for flooding problems in some low-lying areas, such as the Cape Point Campground. Undated file photos.

Wet weather this fall has created a problem of standing water at Cape Hatteras National Seashore, where officials say a high water table is responsible. Quick solutions, though, are not readily available, as various state and federal laws prevent the park from simply draining the water away.

While the national seashore has a drainage ditch system, it was built "decades ago before the Wetlands Protection Act and other modern environmental laws came into existence," says Cyndy Holda, the seashore's spokeswoman. 

"The ditches were meant to reduce water levels in and around Cape Point Campground, which was built in a wetland, but ironically the drainage system had no fixed outlet, so the system holds water rather than drains it."

In years past, she says, the seashore staff would use heavy equipment to trench ditches to drain the water from wetlands areas and roads to the beach. However, when crews did that in 2004 the North Carolina Division of Water Quality issued a Notice of Violation to the seashore for violating state laws that prohibit draining wetlands, the spokeswoman added.

"The NPS has studied the issue for several years, and there are no easy fixes (such as cutting a "drain" any time high water occurs) that would be legal or appropriate," Ms. Holda said. "An NPS hydrologist and a wetland ecologist have visited the area since 2004 and written technical reports stating that the 2004 action not only violates state and federal law, it also violates NPS policy. Their assessment is that the area floods because of an elevated water table; in essence, the water table is 'above ground level' wherever there is standing water, which occurs over an extremely large area.

"The most practical long-term solution, with proper planning and compliance, may be to raise the road and provide proper drainage underneath the road, particularly since flooding seems to be occurring more often in recent years," she said.

Areas impacted by heavy rains this fall (after Hurricane Irene) include the wetlands surrounding portions of Lighthouse Road near the Cape Point Campground and beach Ramp 44. A section of the eastern end of the road several hundred yards long has been under 6-12 inches of standing water for weeks, said Ms. Holda.

"ORVs have generally been able to drive through the water to reach Ramp 44, which for the most part has remained dry. Though not as convenient as Ramp 44, ORVs have also had reliable access to Cape Point from Ramp 49," she said. "We realize that some people would prefer that we simply cut a ditch (the "drain") to the ocean, like in the old days, to lower the water level across a large wetland area enough to reduce the standing water on the road; however, as stated previously, that would violate laws and policy and would not be appropriate in a unit of the national park system."

This coming winter the seashore staff plans to begin work on an environmental assessment that would evaluate the impacts of proposed infrastructure improvements. That document is expected to look at the options for addressing "the flood-prone eastern portion of Lighthouse Road," said Ms. Holda.

I am a resident of Hatteras Island so trust me I know what I am talking about and if you don't believe me read the administrative history--Cape Hatteras National Seashore the Depression through Mission 66.

Hatteras and Ocracoke Islands are home to 8 villages which date back hundreds of years with grave yards to prove it. It is thought that Hatteras Island may be the home of some of the lost colony residents.

Hatteras and Ocracoke Islands are the last of the states barrier reef islands that are populated with the population totalling 4,000 people and a rich tradition of fishing and tourism which revolves around free and open access to the beaches of the islands.

The park service convinced residents to convey their land to the park, resulting in villages that are surronded by government property and at the mercy of government agencies for the ability to maintain their infrastructure by promising to allow continued traditional use of the island's beaches while protecting said beaches from the type of development seen in Nags Head, Kitty Hawk, and other villages to the north.

During the past 15 years or so the 4,000 residents have had the same government agencies stand in the way of infrastruct replacement and maintainence (bridge, roads, restrictions on maintainence of established waterways, etc.) threatening the health and welfare of the people. More recently, the residents have seen continued attempts to establish wildlife and research areas that minimize human presence on many of our beaches--the primary draw for the tourists the park promised to attract to the area.

In this instance we have an area where the park has violated its own mandate to protect natural processes by way of man made ponds, etc. The raised water table has destroyed maritime forest and bird nesting habitat. The raised water table has also limited the use of the area for recreational purposes--a use the park service promised to protect. And we, the residents are asked once again to pay the price.

Am I the only one that sees the above as a slow process of trying to depopulate these islands so that the environmental entities can finally say the entire barrier island chain is now available for birds? Sorry, we residents have a right to be here and those who trace their lineage back to the first colonies and the indians will fight for that right. I will join them. The rest of you should as well. It is a travesty when the government can force people from their homes by standing in the way of basic necessities (such a water in Tomestone and roads and electricy here) and the life blood of the local economies (such as farming in the CA valley and tourism here) all in the name of some fish or bird which can be protected by less extreme measures.


I preface my statement with the words "I pray to God that what I am about to say is wrong."

I've seen very little that the park service has done to make this island a friendly place. The park service continuously looks the other way when there are problems and blames someone else.

What better way to destroy the vitality and economy of this island than to once again look the other way when swarms of west nile virus carrying mosquitios proliferate in the wet lands created and protected by the park service? Once again the park service will conveniently look the other way when a case of west nile virus on Hatteras Island is finally reported. That will surely be the final nail in this economy's coffin.

I must ask would you come anywhere near this island for your summer vacation or would you go somewhere else? As a resident I would seriously consider leaving.


This was not a wetland until the park dug a hole to save the light house, allowed it to fill with water and become a pond, then stopped managing the pond allowing it to grow by leaps and bounds after every hurricane and overwash event since the 1960's and raise the water table. Don't belive me go read Aycock Brown's Outer Banks--he has a picture of the area along with campground, picnic area, Amphitheater.

The hydrologist mentioned is a paid for park service contracter that will say what ever the park service wants him to--like saying the campground spetic system is not compromised and that bacteria levels are within norms. As Wheat pointed out this is untrue.

We have been complaining about this area since Isabel in 2003 and the record spring rains. Isabel flooded much of the island with ocean overwash, cut the island in several places and left Hatteras Village under water and without access to the rest of Hatteras Island for months. Clearly, this was an event that qualified us as a disaster area and would have allowed draining in some of the areas most affected. They did this in the gulf after Katrina, and Isabel was our Katrina.

Contrary to the reports from Cyndy we have not had anything more than average rainfall and we had .53 inches this week and a whopping 2 inches the week before, most of it 10 days before the decision. And don't tell me the ground was saturated because March was below average and April was only a little above average. I repeat this is an ongoing problem caused by man made activities that raised the water table and created a holding area for ocean overwash from south beach. I mean if the park service really gave a damn about visitors, they could have built a new campground and recreational support by now--they have only had 9 years to fix the problem. Furthermore, the park service promised residents the new long range plan would include a solution to flooding and health risks associated with it. Of course, the park service did not address this issue in the plan, except to raise the road. Now we have a new swamp, skeeter problems, etc.

Put it back the way it was (fill the pond, bulldoze the dunes, etc.) or manage the area--period.


This is not an ORV issue, pedistrains would have to walk through that water. We don't have an ORV and did not want to walk through the water. So we had to drive nearly 10 miles to find another beach access. 
It seems that NPS spends less on maintenance and more on control and enforcement. The NPS certainly has its priorities screwed up.


Everyong is making this an ORV issue like everything else there.  It is an access for everyone issue. 
Some of us do not drive on the beach so this is my two cents about it.
  I have a regular little car...sorry but when I was there I had to turn around because it was up to the bottom of my doors. I wasn't going to risk it to see if it got any deeper, just to much.  And I sure as crap wasn't going to wade through water I couldn't see the bottom of it.  It was dark and smelled bad.  We could not make it to the parking area for us non beach driving folks so that eliminated us from enjoying the point this year. It is a long enough hike from the parking area there that my husband struggles from there, if we parked in a parking area further away we could not hike to the point.
 If the NPS wants to keep the visitor count down to certain areas of the beach, well this is just another way of doing it by limiting the access by not maintaining the park as it should have over the years.  I cannot imagine trying to camp in the campground anymore.  It used to be a dry campground when we used to stay there, now it is wet!  And it has not been in that many years to say that the sea level rise or water table etc has caused this. 
It is sad to see the management of the park become such an un-visitor friendy place.  It has been my favorite NP for over 30 years due to its beauty, diversity, history, people and nature.  And to each year I visit see it become a place where visitors are not wanted and the park not cared for in a mannor that protects it (properly) and makes it accessable to all visitors is a shame.  They have an opportunity to make this stand out above the rest but choose not.  again shame on them.


If you are worried about contaminated water in the National Park I think you be more concerned about how it got contaminated rather than draining it into the ocean where it could pose a problem to someone fishing on the south beach.

True, where is the research for that...

In case you’re missing the point, (you are
probably not) you can move your vehicle a couple of 100 yards to high ground to
change your flat.  There is no
reason to change a tire in a puddle. 
In any case I don’t know for certain where this contaminated water is
supposed to be or if it is still contaminated.

 

If West Nile Virus was a problem in Dare County
locals would have contracted it and it would be announced in one of the local
newspaper or blogs it hasn’t, it isn’t. Tiger mosquitoes would not locate
themselves just in one habitat next to the road that leads to Cape Point. There
is more of a problem with them breeding in old tires, buckets etc. West Nile
virus and Tiger Mosquitoes are a non sequitur. If you are worried about being
bit by a mosquito that could possibly be carrying West Nile Virus don’t come
anywhere near Dare County or CHNS. There are mosquitoes everywhere.

Though the water is only inches deep please get a flat tire, then proceed to drop a lugnut into it causing you to have to reach in and look for it not knowing that by doing so you are endangering your life...

Did you take samples of that water you were in?
With an incubation period of 2 to 15 days for West Nile and the average stay on Hatteras being only 7 days I guess there is a SMALL chance these people were diagnosed elsewhere after leaving... Perhaps they did not recognize the symptoms? Or maybe theyare like the other 4 out of 5 that do not have symptoms???
