The paper shows some preliminary results and reflections generated in the research that is carry out in the Master in Urban Management at Piloto University of Colombia, it is about the metropolitan relationships between Bogotá and Soacha, under the residential segregation phenomenon and daily population mobility; specifically it discusses the implications generated by the macro-project 'Ciudad Verde' (Green City), in this sense, it studies if the project execution has repercussions and implications for their inhabitants. The discussion leads to the next question: Whether the development of a housing macro-project as Green City would generate residential segregation? In that sense, the results describe some relevant findings and suggest that in terms of mobility conditions, there is a serious deterioration due to the impact in the reduced family budget, which implies an over cost due to the need of using more than one transportation mean, as well as higher travel time.
