The war in Ukraine exacerbated certain behavioral reactions of the social groups selected for the study. The city, as a complex socio-economic mechanism, has the opportunity to monitor the manifestations of atypical reactions of these groups and, based on these manifestations, to determine indicators of long-term and preventive impact. The authors argue that such indicators are currently lacking in long-term planning systems of large cities, especially for wartime planning and management as a high-risk, dynamic context. Examples of the manifestations of two characteristic indicators are given, which relate to certain social groups exposed to the influence of increased mental stress caused by such a phenomenon as war. The research methodology is empirical, as well as based on focus group discussions and document analysis. 3 types of index frameworks are considered, namely: the context of wartime work planning, the index of coverage of members of society with incomplete functionality, as well as the mechanism of long-term forecasting in response to changes in external factors. According to the authors, the need for careful planning in situations of high uncertainty makes the risk factor and especially its impact component among the priorities for analysis and decision-making. That is, if the risk is high and the consequences are dire, you should engage in the potentially risk-generating direction first. During the war, you will have several such directions, from which you can select those that, in case of implementation, carry the largest risk impact and the moderate, “background” risk impact. With regards to the members of society with incomplete functionality, it is good to display regulatory signs such as "red flags" or "blind spots" which will allow to either focus their attention on something important, or limit their view so that they are not distracted, so there is a chance to prevent further destruction. With regards to the priorities of the economic behavior of households that formed based on the undistributed income available to them and on new/existing regulatory norms or other "windows of opportunity" in the market, this significant factor for the development of the city shall be analyzed preventively because some household purchases can significantly affect the ecosystem of the city and ultimately its economy.
