The main objective of the research is to map the socioeconomic and housing profile in the Burío-Quebrada Seca micro-basin in order to favor the implementation of restoration, conservation, mitigation actions in the fluvial system and territorial ordering in the study area. The methodology was composed of three main stages: description of data, preparation of data in the database manager, and publication of data with the community.

In parallel, since 2005, the Constitutional Chamber issued the vote No. 4050, in which it ordered the formation of an Inter-Institutional Commission.

There is a predominance of urban residences in the micro watershed, 97.5% of the dwellings are in this area. Almost 87% of the homes in the study area correspond to independent houses.
