Establishment and Implementation of Detailed Parameters of Functional Zones in Master Plans of Large Cities on the Example of Nizhny Novgorod, Perm and Tyumen

The article examines the implementation of city master plans in terms of the parameters of the planned development of functional zones in order to identify the most feasible indicators. An analysis of 17 cities was carried out and the main parameters used in Russian practice were identified. Large cities that have in their General Plans a set of parameters close to the regulations of the Land Use and Development Rules, and whose implementation period has come to an end in 2024, are examined in more detail: Nizhny Novgorod, Perm, Tyumen. The implementation of the assigned parameters of density, height, built-up area, greenery, percentage of commercial functions inside residential buildings using geographic information systems is analyzed. This is especially important in connection with the emergence of a new document in urban planning practice, combining the General Plan and Land Use and Development Rules. International experience in the field of urban regulation is considered, including in China, Brazil, India, and the United States of America, and analogies are drawn with Russian practice. The study collected and used a lot of data from various open sources, such as the Housing and Communal Services Fund, Wikimapia, approved parts and materials on the justification of city master plans, Open Street Map. Geoanalytics was carried out in the Python programming language.
