In most small island contexts, the costs of adaptation through accommodation are prohibitive so that it has in most cases not been contemplated as a widespread option. However, accommodation measures such as the raising of dwellings and key infrastructure like coastal roads above ground level have been implemented to reduce the impacts of flooding in some islands . In the most populous islands of the Tuamotu atolls, French Polynesia, where between 48% and 98% of dwellings have already experienced flooding since the 1980s, elevated houses with floors built 1.5 m above ground level are subsidised by the government as part of risk prevention plans . Despite this incentive, the opposition of the local authorities and population to these plans  considerably limited implementation, hence elevated houses only represent 7% of the total housing stock. In the Philippines  and Indonesia , residents have elevated their houses by building stilted houses or raising the floor using coral stones to face increased flooding . Also, in Puerto Rico houses have been raised to address flooding .
