Given that cities have the majority of the country's population and are often the economic, political, cultural, social and governance centers in countries, theirreadiness against crises (passive defense) should always be considered by the relevant experts. Organizing the city on the scale of the neighborhood (as the smallest and most effective urban unit) based on the requirements of passive defense, in order to deal with the crises (natural and man-made) and minimizing the hazards using geographical techniques and urban planning, are the objectives of this research. Therefore, the sixth district’s neighborhoods of Tehran’s 2nd region were selected as a case study and the results of the research were presented so that the possibility of generalization of similar surveys and studies in other urban areas would be provided. The present research is an applied- type, and the method of the research is normative-analytical. The scientific foundations of this research are based on the concepts of urban crisis management with an emphasis on geography and urban planning knowledge. In this research, after the recognition and evaluation of the present situation, the dimensions of the vulnerability of neighborhoods at the time of the crisis, the strengths and weaknesses, as well as the threats and opportunities of each neighborhood have been investigated with the passive defense approach, and the relevant conclusions have been drawn on this basis. Data collection was done based on library method and field studies, and a comparative method was used to provide the conclusions. In this research, the SWOT analytical technique was used to determine the strengths and weaknesses, threats and opportunities, as well as to provide strategies, policies and suggestions for necessary actions, and ArcGis software was used to display and analyze the descriptive data. The results of the research indicate that the attention to components such as city structure, urban texture, city form, urban land use, and finally the social contributions of residents of each neighborhood, can make it possible to organize urban neighborhoods based on the requirements of passive defense. The results of the research reflect the fact that paying attention to the components such as city structure, city texture, city form, urban land use, and finally the social contributions of the residents of each neighborhood, can make it possible to organize urban neighborhoods based on the requirements of passive defense.
