They often constitute a large area directly adjacent to the city structure and are exposed to urbanization pressure, and on the other hand, they are often potential hydrological windows. The approach to the development strategy for such areas should take this potential into account. The article presents the example of Cracow (Poland) and post-industrial areas constituting the hydrological and bioretention potential in terms of the possibility of their development and the legal aspects of the development strategies of these areas.

Introduction Hrehorowicz-Gaber, H.; The world is becoming more and more urbanized, with larger, denser conglomerates Hrehorowicz-Nowak, A. Adaptation of buildings. Compact cities are perceived as more energy-efficient and resource-efficient, of Post-Industrial Areas as but they have an influence on the intensification of microclimatic effects. Areas of thermally Hydrological Windows to Improve massive, impermeable surfaces, typical of dense urban centers, store heat, distorting the City’s Microclimate.
