"This
is suppose to be the time of year the lakes and ponds freeze and our
ocean was supposed to be covered with multi-year ice and freezing to
make it anchor along our shores to block the strong winds and waves
from penetrating onto our coastlines. [The] only difference is warmer
winds and no ice."
Autumn
storm batters northern coastline
6
October, 2017
Cleanup
and recovery from the recent storm that battered the North Slope
coastline may carry a price tag exceeding $10 million, borough
officials say, following an assessment of the damage to beaches,
roads and other infrastructure.
"Utqiaġvik
sustained severe losses and threats to property and life due to wind
and high surf storm surges over the course of several days,"
noted a storm statistics sheet provided by Kenneth Robbins, advisor
to the North Slope Borough Mayor.
Sustained
west winds in excess of 30 mph, combined with wind gusts of more than
45 mph, washed water and sand over access ways and transformed roads
into beaches.
The
town saw waves and surf of 8 feet or greater, which damaged the
fragile coastline and carved out fingers of beach near critical
infrastructure.
"We
had a major storm surge way back in the 1960s, I have heard, and it
was very devastating," said local resident Robin Mongoyak. "I'm
afraid lives will be lost and homes will be destroyed if there is
nothing serious done [to prevent it happening again]."
A
handful of Utqiaġvik's roads were damaged or completely destroyed by
this storm, which began Sept. 28 and continued for several days.
"The
beach road from the Point Barrow Airstrip and Elson Lagoon,
approximately 3,700 feet, is completely destroyed, separating the
community from an important subsistence area," the borough
noted. "Whaling in the community, a critical subsistence
activity, commenced shortly after the storm subsided and access to
Elson Lagoon is very important for landing whales if wave action on
the coast presents an unsafe situation."
Pictures
taken by people who have braved the conditions to get a better look
at the damage show beach debris covering what used to be a graveled
and graded path. Road signs spring up from the sand and pools of
water, seemingly out of place, but in actuality, marking what used to
be there.
According
to the borough, Stevens Street between Tahak and Ahmaogak Avenue was
covered in water. The approximately 3,000 feet of road was "severely
eroded from storm surge wave action and portions remain closed."
Additionally, a 200-foot section of Egasuk Street was also washed
away, along with 60 feet of guardrail. Stevens Street was also
compromised between Agvik Street and Eben Hopson Street. That portion
remains closed, as well, due to erosion and water damage.
Other
critical infrastructure was also damaged or put at serious risk by
forceful flooding and surge.
As
happened during a powerful storm that wreaked havoc on the community
in 2015, Utqiaġvik's freshwater source was nearly compromised. Both
the lower and middle lagoons below the freshwater lagoon were
flooded. As the lagoons are all connected, rising water levels in the
brackish lagoons can lead to backflow toward the freshwater lagoon.
"Responders
plugged freshwater outfall culverts to prevent saltwater
contamination of the freshwater lake," the borough explained.
In
addition, 22 lots on both "Barrowside" and in Browerville
were flooded during the storm and remained submerged as of Tuesday
afternoon.
The
flooding was in part caused by a failure of more than three miles of
protective berms that run the length of the coastline. The berms were
breached or "severely eroded" in several areas along that
3-mile stretch, allowing overspill of seawater.
The
borough noted it had purchased 15,000 cubic yards of gravel for berm
repairs, which were about 80 percent complete by Tuesday afternoon.
Part
of the retaining wall system that runs below Egasuk Street was also
weakened by the storm. It's the first damage the wall has sustained
in a decade, borough officials said.
It's
a 600-foot Gabion basket wall, which is basically backfill material
supported by sturdy exterior mesh. The borough noted several of the
"baskets" were "emptied" by waves and the full
extent of damage is not yet known. However, because of how the system
supports itself along the entire length, "Now the entire
structure is vulnerable," the borough stated.
About
1,200 feet of super sacks — giant one- and two-ton sandbags —
between Egasuk Street and Barrow Utilities and Electric Cooperative's
Pump Station 4, sustained heavy damage and must be replaced, as well.
Finally,
serious and swift erosion has taken its toll on the ground beneath
portions of town. The future of those compromised sections is now
uncertain.
"Seven
historical town site lots on a bluff below Apayauk and Stevens Street
have been undercut by storm surge wave action and the top of the
bluff along its entire length is unstable and beginning to collapse,"
the borough noted. "It is estimated that the top of the bluff
may recede as much as 10 feet after the supporting soil thaws."
This
level of erosion is not uncommon after storms of this magnitude.
Parts of the North Slope coastline have lost more than 60 feet over
the last several years due to increasingly damaging fall storms.
"Not
every year it's like this, but it still gets stormy. But, when it
comes, we are only [temporarily] ready," said resident Mongoyak.
"This is suppose to be the time of year the lakes and ponds
freeze and our ocean was supposed to be covered with multi-year ice
and freezing to make it anchor along our shores to block the strong
winds and waves from penetrating onto our coastlines. [The] only
difference is warmer winds and no ice."
The
loss of protective sea ice means storms barrage the land itself and
now carve out swaths of it as they progress. The inundation of warmer
water on the permafrost also encourages thaw, making coastal areas
even more prone to erosion down the line.
Last
year, North Slope Borough officials met with the U.S. Army Corps of
Engineers to revitalize discussions of building a seawall to protect
the hub community from these disastrous fall storms.
"[Utqiaġvik]
is just one storm away from a major catastrophe," said former
borough official John Boyle, speaking to the Sounder last February.
"Not only could it have catastrophic impacts on the community of
[Utqiaġvik] itself, it could also have impacts on the rest of the
North Slope communities that rely on [Utqiaġvik] as a hub."
Those
conversations are ongoing, though no decisions on precisely how to
proceed have been made yet. This is the most damaging storm to hit
since the big one two years ago and now residents know it's a
question of when, not if, that catastrophic storm will hit.
Out
on the road to the old air strip, cabins that once sat 60 feet or
more from the waterline now have waves lapping at their doorsteps.
The freshwater lagoon has come within inches of contamination not
once, but twice. The supports are failing and the bills to fix them
are rising.
Looking
out at the ever-narrowing distance between their community and the
encroaching sea, residents are becoming increasingly uncertain about
what the future of these storms will mean for them and the place they
call home.
