Abstract: The article presents the results of comprehensive engineering-geological investigations carried out within the studied site using field, laboratory, and analytical methods. Based on drilling operations, sampling of undisturbed soil specimens, laboratory determination of physical and mechanical properties, and static cone penetration testing, the geological structure of the soil mass down to a depth of 11.8 m has been established. The spatial heterogeneity of the Quaternary deposits forming the engineering-geological profile of the area has also been characterized. Several genetic types of soils were identified within the site, reflecting the complex history of natural and technogenic processes. These include modern technogenic, eluvial, aeolian-deluvial, lacustrine-glacial, and glacial deposits of Upper and Middle Quaternary age. Their coexistence within a single geological profile indicates a long and multi-stage evolution of the relief and geological environment, which significantly affects the engineering behavior of the soils under load. Based on grain-size composition, natural moisture content, Atterberg limits, consistency indices, and cone penetration resistance, 11 engineering–geological elements (EGEs) were identified. Each element is characterized by its own physical and mechanical parameters, degree of heterogeneity, and formation conditions. The substantial vertical and lateral variability of the EGEs creates complex conditions for foundation design and for predicting the deformation behavior of the soil base. Special attention was given to soils with specific or unfavorable engineering properties detected within the section. Laboratory data show that these soils are sensitive to moisture variations, stress-strain changes, and seasonal groundwater fluctuations. Certain layers exhibit increased natural moisture content and elevated compressibility, making them prone to reduced bearing capacity, differential settlements, and deformation processes under external loading. Hydrogeological investigations determined the groundwater level at a depth of 3.3-3.8 m at the time of research. According to classification criteria, the territory is considered prone to periodic flooding. The combination of shallow groundwater and heterogeneous soil conditions significantly complicates engineering design and requires careful consideration of potential seasonal fluctuations in the groundwater regime. The study provides a forecast of potential changes in engineering-geological conditions due to future land development. It is shown that an increase in technogenic loading-through construction activities, changes in relief, soil compaction, or alteration of drainage conditions-will inevitably lead to additional stress redistribution within the soil mass, modification of the groundwater regime, and changes in soil properties. These factors may trigger differential settlements, localized decreases in bearing capacity, and activation of adverse geological processes such as suffosion, filtration deformation, and intensification of flooding. Given the identified features of the geological structure and hydrogeological conditions, a set of engineering measures is recommended to ensure safe and efficient land use. These include the installation of surface and subsurface drainage systems, the application of reinforced or deep foundations in weak or water-saturated soils, the use of pile or combined foundation systems in zones of increased heterogeneity, and the implementation of monitoring programs for groundwater levels and soil behavior during construction. The results of the research provide a reliable basis for engineering design, risk assessment, and urban development planning in areas with complex geological conditions. The presented engineering–geological analysis enables a comprehensive understanding of the soil environment, prediction of its behavior under technogenic influence, and formulation of scientifically grounded recommendations for further development of the site.
