Intensive development of underground space in large cities causes the necessity of its economic assessment taking into account environmental factors. Development of methodological bases of ecological and economic evaluation of underground space requires analysis and consideration of its features as a natural and economic resource. Urban underground space is formed under the influence of two environments (urban environment and the subsoil) and has the properties inherent in both. Features of the urban environment are a large concentration of people, the specificity of the use of space and the high variability of conditions over time. The subsoil is characterized, as a rule, a high density of the environment and isolation from the surface.
