Urbanized areas are considered as single natural and technogenic systems. Ensuring safe development of urban areas is associated with natural risk assessments. It is proposed to carry out a special zoning of urban areas. In the selected areas, risk is formed according to certain scenarios. The proposed zoning involves a successive subdivision of the city territory by natural and technological factors using usually only one feature at each step. As a result, we come up with relatively homogeneous areas. Thus, a consistent division of a total into parts for each group of factors is achieved. Various combinations of these factors are also taken into account when distinguishing typological taxons.

Keywords: urban area, natural and technogenic factors, final zoning taxons, zoning criteria, typification criteria, index designations.
