During the 1940s,
the shore erosion steadily
progressed inland at Bogue Point. By 1949 the shoreline at the point
stood back
almost to the position it had occupied at the completion of the
engineer
operations in the 1880s. During the 1950s, new erosion problems fueled
by a
series of violent hurricanes and storms left the stability of Bogue
Point and
the safety of Fort
Macon in question.

In the summer of 1952, heavy erosion took place on the
inlet beach northeast of the fort. It undermined two public toilets at
that
location, one of which actually fell onto the beach.>
State and federal officials took immediate
action because of the threat to the sand dunes protecting the parking
lot. A
local company was contracted to strengthen existing jetties at this
location
and construct a stone breakwater wall to protect the beach during
January to
March, 1953. Some $25,000 were secured for the work from the State
Contingency
and Emergency Fund.
On
the ocean side, however, erosion was becoming a concern southwest of
the fort
during 1953 and 1954. One particularly bad summer storm during July
8-12, 1954,
was responsible for undermining two massive 30-foot diameter concrete
gun
mounts installed in World War II for 6-inch guns. These collapsed onto
the
beach. Unfortunately, more storms were on the way.
Hurricane
Hazel on October 15, 1954, did great damage to the ocean beach and
Bogue Point.
At the bathhouse area, the storm surge swept through the dunes to
within a few
hundred feet of the park highway. At Bogue Point storm surge swept over
the
barrier dunes into the fort parking lot. Hurricanes Connie, Diane and
Ione in
1955 were far less severe but added to the overall destruction of the
primary
dune lines.
During
1957-58, storm tides cut away the ocean beach right up to within eleven
feet of
the park road south of the fort, leaving an eroded embankment dropping
off from
the road shoulder. The waves crashing against the embankment at high
tide
splashed over onto the cars of park visitors passing by. The N.C.
Highway
Department was able to save the road by building a rubble breakwater at
the
foot of the embankment at a cost of about $7500.
However,
it was clear that more lasting measures were needed both to secure the
park
road and the fort parking lot. On April 22, 1958, the Governor allotted
a total
of $50,000 from the State Emergency and Contingency Fund to rework
several of
the jetties and replenish the beach with dredge fill.
The
project for beach fill and jetty repair
began in September, 1958. It involved reshaping the jetties on the
point and
strengthening two of them with 1260 tons of new granite stones. In
October, the
dredging part of the project began with 100,000 cubic yards of spoil
being
piped onto the beach at two locations. The total cost of the project
was
$48,538.38.
The new
fill
helped the beach but after only a few months erosion was cutting back
into it
again. Fortunately, the 1959 N.C. General Assembly appropriated
$150,000 to
continue erosion control work at Fort Macon
State Park.
Additionally, the Army Corps of Engineers
was asked to conduct a study of the erosion problem jointly with the
state to
determine long-term solutions. Hurricane Donna on September 12, 1960,
showed
the need for more permanent efforts. The hurricane wiped out the whole
dune
system on the point and caused widespread erosion. As a result, it was
planned
to use an extensive rock seawall at Bogue Point to stop the antics of
the sea
by simply walling off the point. In accordance with the Corps of
Engineers’
recommen-dations, the seawall would be made to pass around the point
but then
extend straight out into the ocean parallel to the ship channel as a
sea jetty.
In this way, it was believed the jetty would trap sand being carried
eastward
in the shore currents and hopefully build up in front of the fort
naturally.
Accordingly,
work on the project began in July, 1961. A seawall was begun northeast
of the
fort and extended around Bogue Point southward into the ocean as a sea
jetty
parallel to the ship channel in the inlet for 675 feet. The
seawall-jetty
system was 1250 feet long in all. The area between the wall and parking
lot was
backfilled with sand. Steps were built to provide access to the beach
over this
wall for the public. The work was at last completed in mid-April, 1962,
at a
cost of $145,380.29.
Meanwhile,
the
results of the Army Corps of Engineers joint study on erosion came out
in early
1962. The study recommended further work to be added to what the state
had just
completed as part of a joint state-federal erosion control project.
This
project would cost an estimated $583,100, shared by both state and
federal
governments. The project would result in the creation, when finished,
of a
seawall-jetty system 2450 feet long. The additional 1200 feet needed to
finish
this system above what had just been completed by the state would be
added to
the length of the jetty portion of the system paralleling the ship
channel.
This would both save Bogue Point and reduce the amount of silt clogging
the
ship channel.
The
state then
prepared to go ahead with another part of the overall project with an
appropriation of $260,000 by the 1963 N. C. General Assembly. The funds
would
be used to extend the sea jetty over 400 more feet and renourish the
park
bathing beach with dredge fill. An additional jetty was also needed to
halt
erosion occurring behind the extreme north end of the seawall.
Work
began on
this second phase of the beach erosion project in August, 1965. First,
a new
jetty was built on the north side of the point. Work was then done to
extend
the main sea jetty 410 feet further using stone brought up by barge. A
dredge
contract was also included in the project. It called for 100,000 cubic
yards of
dredge material to be pumped onto the bathing area. Both the
construction and
dredge projects were completed during the fall of 1965 at a cost of
$305,360.
The
result of
the work was mixed. The extended sea jetty continued to be effective in
building up the beach at Bogue Point with accretion. The dredge spoil
at the
swimming beach was not so successful. During the 1966 summer season,
visitors
turned loose a storm of complaints at having to climb the 8-foot high
berm of
dredge material studded with clay chunks and sharp seashells. The sea,
meanwhile, ate away at the ocean side and created a high cliff. Within
two
years most of the material had eroded away, allowing storm tides to
undermine
the park bathhouse in December, 1967. A new bathhouse was built further
back
from the beach in 1968.
The
state,
meanwhile, went ahead with plans for the third and final phase of the
beach
erosion project. Work began in January, 1969. A new jetty was
constructed east
of the new park bathhouse to force the buildup of sand at the swimming
beach.
More dredge fill was pumped onto the swimming beach during May. Once
again, a
high berm was created that sparked heavy public protest.
The process of extending the big sea jetty 540
more feet began in the spring of 1969 and was completed in August,
1970.
Including the seawall portion, the total length of the seawall-jetty
system was
now 2250 feet, only 200 feet short of what the Corps of Engineers had
proposed
in their 1962 study. The conclusion of this phase of the project marked
the
last attempt at hard stabilization of the beach against shore erosion
in Fort Macon State Park.
As an
evaluation of a century and a half of work to control shore erosion at Fort Macon,
the shoreline of the park has now remained basically stable behind the
bulwark
of jetties. The big sea jetty has been most successful in keeping Bogue
Point
intact. In the late 1990s, some portions of the jetty were at times
completely
covered over with sand.
Since 1970, the ocean beach of the park has
been renourished with dredge fill by the Corps of Engineers during
1977-78,
1993-94 and 2002. In each case, the amount of time the fill material
remained
on the beach before being washed away varied. At present, dredge
material is
being pumped on the beach once again in 2005.
As long
as the
structures built for the protection of Fort
Macon over the years remain
intact, it
is doubtful that Fort
Macon will ever be
seriously threatened by shore erosion again. The most vulnerable part
of the
park beach will continue to be the middle and western sections,
including the
bathhouse area beach. Thus, the battle between Fort
Macon and the Atlantic Ocean can never be considered as being
over.
