The article presents the results of the development of software tools for controlling and monitoring the impact of urban filling stations in urban development, which allows an interactive assessment of the environmental safety of existing or newly built city filling stations and a list of measures to reduce their negative impact on the environment. The software toolkit is designed in the MVC style, supports its own data storage format and is implemented using the Microsoft Visual Studio programming system using WPF and .NETCore technologies, in the C # language. When working with software tools, the user is provided with the following functionalities: filling out the petrol station questionnaire (number, name, address and date of the initial assessment of a particular petrol station), saving and loading a session on working with the assessment of a particular petrol station, assessment, calculation and cyclical improvement of the indicator of the environmental assessment of petrol stations (the choice of measures, depending on the obtained primary indicator of environmental safety), until the maximum possible class of environmental safety of a particular filling station is achieved and reporting on the resulting assessment.
