The Tropical coast of Granada Province, in Southern Spain, was intensively developed during the 80s and 90s., A residential complex of several urbanizations, was built up on the Eastern slope of the coastal Cerro Gordo hill (Almuñécar), on the pre-existing landslide of Calaiza, unidentified in the preliminary technical studies, thus giving rise to a set of incidents associated with this unforeseen unstable slope. To insure sea views from all houses, excavations and fillings were practiced giving place to a stepped slope on which new foundations of structures and roads were located and subsequently progressively damaged by increasing cracks and deformations, leading 42 houses into ruins in the period 2003-2016. Since 1990 annual and monthly rainfalls were variable in the area, and some peaks of rainfall eventually were associated to damages proliferation, although more frequently damages were recorded during dry or low rainfall seasons, when water infiltrated from pipelines breaks. This expressed the damaging effects of a combination of permanent sliding at low annual rate and bad constructions practices during eventual heavy rains or dry periods. An overall perspective of the geotechnical and geomorphological features of the study area, the landslide reactivation, and its correlation to the evolution of damages, as well as its legal consequences, is presented.
