Coastal Engineers, Scientist and Consultants

The Dune Science Group lives on its commitment to help preserve and restore the World’s coastlines to be as safe and productive as they can be, given the pressures caused by human desire to enjoy the coast.  We concentrate in two areas, that of employing natural and nature-based processes in the restoration and protection of the coastal dunes  and then providing the most cost effective, environmental acceptable beach and water access structures to protect these system without slowing enjoyment of the coast.

We fully respect and appreciate the fact that there are many other firms and individual consultants that share our commitment to the coast, folks that specialize in everything from beach nourishment, sand bypassing, artificial dune construction, including strengthening with an engineered core, and  those who restore dunes using methods similar to those of the Dune Science Group.  With so much good work that needs to be done on the coast, we don’t view that we have competitors among the group, just potential partners and collaborators to help Clients best achieve their goals.  We welcome the opportunity to work with you in these special areas

Dune  Walkovers (and marsh walkovers)

One area where we feel we really have no competition is our understanding of the options for beach access that are economical and user friendly.   Our walkover designs rely on fiberglass and fiberglass reinforced components that are 100% free of wood and wood fibers.  The materials we specify have many advantages over pressure-treated wood because of the high strength to weight ratio of fiberglass.  It is also inert, helping all of the component we specify having a 50 year plus life even on the beach or marsh without requiring saturation with arsenic and other toxins to extend its life.  These toxins can find their way in both during installation but also during the annual maintenance required by these structures.  All of our materials require little or no maintenance during their life, including no recoating.  Our designs have decking that does not warp or sprinter.  We use only 316 stainless steel to give long life for connectors. We only specify materials with low thermal expansion to prevent “thermal working and breaking” of components at connectors.

“Fiberglass” might sound industrial but the reality is that DSG specifies walkover materials with wood grain finishes that look like wooden walkovers but they keep that look much longer because of additives that resist UV ray on decking and railings.  Other additives reduce the slipperiness of even wet deck to well below natural wood grains.  And we also take advantage of heat reflective skin coat additives on decks and railing to reduce burning of tender bare feet on a hot sunny day.   A variety of color options are available, colors that only slowly fade, even in the strongest UV and salt air exposures

The DSG welcomes the opportunity to partner with those needing to provide safe, convenient access to the beach or water for their clients.  We are prepared to provide them turnkey or we can design and manufacture the structures for installation by others.

Dune Restoration and Dune Enhancement

Once sediment is in place, in existing dunes, on the dry beach or built into an artificial dune shaped pile of sand, the Dunes Science Group is prepared to take the next step to protect and naturally enhance the dunes and beach.  Our instincts are to rely as much as possible on vegetation native to the dune and beach to achieve these goals.  Will do employ as necessary other permitted methods including sand fencing but we prefer to move to vegetation as soon and completely as possible because we believe it forms a dune structure that is stronger, more aesthetically pleasing, provides position input to the dune as a home for a variety of flora and fauna, all at the lowest cost  available.  Our active research program looks to more fully understand the natural dune processes we are trying to simulate and assist.

The Bottom Line 

The Dune Science Group name reflects its characteristics, it is focused on the coastal dunes, relies heavily on science, and projects that it will best accomplish its goals by working with other as teams or groups trying to achieve the same goals, all for the benefit of the clients. We welcome inquiries from other coastal firms and consultants to identify how we can collaborate on current or future projects important to the coast and our Clients.
