Why Building On Sand Dunes Is Not A Good Idea

It is very important that any one who has bought or is considering purchasing a lot on a sand dune,

is made aware of the risks, problems, and dangers associated with building on it.

Sand dune systems are nature's buffer strip between the sea and land, and they are vital as a defense mechanism against the erosional actions of the sea, and the inland drifting of sand caused by wind erosion. Human interference with sand dunes by the removal of vegetation and the construction of roads and houses can have a substantial effect on dunal stability. Besides decimating a habitat full of native plants and soon to be homeless creatures, here are two other major existing risks:

1. Stability risk - is a result of the mobile nature of sand, which makes up the sand dune. The removal of vegetation, coupled with exposure to the wind, can lead to the erosion of the sand dune, and undermine the foundations of a building. Once this action commences, it is nearly impossible to stabilize the situation to prevent the possible collapse of a building. Vegetation plays a vital role in keeping sand dunes stable by holding the sand together and shielding it from the wind.

2. Locational risk - the close proximity of sand dunes to the sea creates immediate risks in storm situations.

Whether or not a sand dune is stable, it is possible on some exposed beaches for storm waves to attack the dunes and transport the sand out to sea. This has occurred here in years past. These situations are mostly beyond human control, and houses nearest the frontal dunes are most at risk. Due to the risks involved with building on sand dunes, it is strongly advised that should you wish to buy or build on a sand dune, then you will be living in a high natural risk area which may be affected by wave or wind erosion resulting in the loss of property and/or buildings.

For years now, the community of Todos Santos has posted signs on our beaches warning potential buyers of these risks, and that we do not support building on our dunes. Yet, in spite of these efforts to educate potential buyers and to build public awareness, two homes have been constructed and a third is going up now. Perhaps it could be stated in a more positive way.. that these efforts have actually not been for naught, since ONLY two houses have been completed. and nobody is buying them. Pity the innocent people from afar who think they are actually able to buy a piece of paradise on a beautiful, pristine beach in Mexico! What a shock to learn, too late perhaps, they were duped, and when something sounds too good to be true, it usually is. - 30 Concerned Neighbors of The Las Tunas Dunes
