The growth of unplanned settlements represents one of the most significant challenges of territorial planning in tropical karst territories. This growth undermines any city’s planning systems, generating irregular, and disarticulated human settlements, a lack of services, and ignorance of lagoons and mangrove ecosystems. This situation is typical of cities northeast of the Yucatan peninsula, Mexico. The absence of a knowledge system of physiographic characteristics of this region has overlooked its karst characteristics that can help adapt the buildings to a highly complex urban system. This work aims to develop a model for recognizing karst depressions and its assessment based on the use of urban land to guide karst action policies in the city. The study was carried out in the city of Playa del Carmen, Mexico. The results show that 364 depressions were recognized, of which 59% are circular and circular to oval sinkholes of less than 1 m depth. Four sectors of the city are distinguished by medium and high housing density, high population density, and high density of depressions (between 50% and 90%). Identifying a sinkhole is based on the principles of remote sensing and geographic information systems so that some spatial units will be overestimated in their number or underestimated in the urban area of the city. The presented analysis model can be implemented in all the northern cities of the Yucatan Peninsula under an ecosystem services scheme of these karst units.
