There is an environmental assessment of construction projects in the Russian Federation. The results of this assessment can reduce the risks posed by projects which are already implemented. Current trends in the development of environmental safety in the assessment should be aimed at improving the level of environmental protection during construction. The environmental assessment of the construction in the region should take into account the optimal conditions for preventing the damage to the population, both during construction and throughout the entire life cycle of the designed facility. The environmental problem of finding the optimal mutual location of objects should take into account a large number of factors that determine the cost of construction of a specific type of objects in a given territory, the cost of organizing infrastructure and the improvement of a given territory. It is necessary to formulate a criterion for the optimal location of objects, taking into account the current environmental situation and to predict the costs of environmental restoration, for example, socially significant costs of restoring people's health. The use of calculations contributes to reducing the environmental burden of the region, improving the quality of life of the population, rational use of territories and resources, which in general will affect its favorable development. The favorable development of all regions, with its natural features, provides prospective well-being of the country as a whole.
