The general layout of future Moscow territory development up to the year of 2025 focuses on structural rearrangement of area use rather than spatial spreading of the urban area due to new construction at newly developed lands. The balance between environmental and socio-economic needs for the sustainable megacity development is the basis of ecological requirements for urban development in Moscow. Special attention is paid to the analysis of geoenvironmental conditions of the urban area. For urban objects, the safety level is established proceeding from a single criterion of the admissible natural risk with the consideration of all probable manifestations of hazardous geological processes.
We performed zoning of the Moscow territory according to its geoenvironmental conditions proceeding from the assessment of the following geohazards: landslides, karst, karst-suffosion processes, and underflooding. Very unfavorable, unfavorable, conventionally unfavorable, conventionally favorable, and favorable categories of geoenvironmental conditions are distinguished.
Geoenvironmental status is always classified as very unfavorable and unfavorable categories in the areas, where disastrous manifestation of natural and technonatural processes is possible. Conventionally unfavorable and conventionally favorable geoenvitronmental conditions are typical for territories, where various combinations of natural and technonatural processes may raise the cost of construction and operation of buildings. Favorable geoenvironmental status is distinguished in the areas with no conditions required for the development of hazardous geological processes.
On the basis of assessing hazardous exogenous processes, we have built the map of geoenvironmental status of the Moscow area to a scale of 1 : 50 000. The distribution of territories of different geoenvironmental status by municipal districts and functional zones was analyzed. The proposals on providing safety of future urban development of Moscow were elaborated.
