In a modern large city, it is mandatory to have playgrounds in residential areas. The level of social well-being and well-being of urban space is also assessed by the presence of a children’s playground in each residential courtyard. However, from a city-ecological point of view, is it advisable to organize parking on boulevards, in small squares, in courtyards next to car parks? In order to understand this, the state regulatory requirements and standards for the organization of children’s playgrounds in a large industrial city were studied; The territories of playgrounds were identified, the location of which raises doubts about the correctness of their placement; a geochemical analysis of natural environments was performed – the surface layer of air, soils and soils, snow cover on the territory of playgrounds and adjacent zones. An assessment was made of the compliance of of the geochemical analysis results with existing standards for the placement of playgrounds in urban space and urban planning solutions were proposed to optimize the locations of playgrounds created contrary to existing standards.
