This
600 foot length of beach in Vero Beach, Florida uses an open grid pattern
to provide protection from the predominate direction of storms while still
allowing access for nesting sea turtles. Duneguard meets the environmental
regulations of the State and local government.
Duneguard
is a dune protection system, similar in appearance to typical dune fencing,
that works with the natural beach system to reduce the erosive impact
of wave run-up on the base of dunes during storms. It is particularly suitable
for narrow beach situations and scarped dune facings. It is also very effective
at capturing both wind-born sand and even sand that is suspended in the
wash. This sand build up acts as a reservoir, giving further protection
to the dune during following high water events. The dune itself is, of
course, both a barrier and a sand reservoir, providing protection to landward
infrastructure, making dune protection a valuable effort.
Duneguard
is a very cost-effective way of preventing erosion and damage to beachfront
property during storms. It is a flexible system that blends nicely with
the seascape and allows for dune shifting. This approach contrasts with
inflexible armoring such as bulkheading which eliminates the natural dune
environment, leaves a harsh appearance and is muchmore expensive than Duneguard.
Duneguard
is made of materials which are UV and salt resistant and long-lasting.
Its anchor system is deep and remains stable under extreme beach conditions.
Duneguard
does not require extensive permitting in most states since it is usually
considered as part of the normal dune maintainance program of a township,
homeowners association or individual private property owner.
Case Study Avalon


In Avalon,
New Jersey a Duneguard system was put in place in June of 1995. It was
placed under and adjacent to the town fishing pier in front of existing
dunes. This had always been a location where the dunes were weak and subject
to overtopping by water during storms and flooding in the streets. This
was due to a focusing of wave energy under the pier which had scoured down
the bottom into a channel for incoming waves. As a result, the dunes to
each side of the pier were smaller and farther back. In the Spring of 1995,
three rows of Duneguard were placed in a V under and immediately adjacent
to the pier, parallel to the shore. Within six months the system had accumulated
sand half burying itself and mounds extending 20 feet away from the grid.
The system had completely buried itself within one year, forming new dunes
in front of the old ones. In fact, Avalon's public works director decided
to plant dune grass over the system to further anchor the new sand. He
was quite pleased to see dunes established in a place where nothing else
tried before had ever allowed dunes to take hold and grow. This area is
quite stable today, despite significant storms of the last two years. Please
see photographs above.
