the average area of Riga neighborhoods. The length of the perimeter of the neighborhood border is . The minimum height of the surrounding relief surface corresponds to the sea level, but its maximum height is above sea level. In the section from Lielupe to Rītabuļļi, the territory is characterized by the relief of small forested, irregular dune hills and deflationary depressions ( above sea level). Almost the whole area of Buļļi is located in the geomorphological micro-district of the Litorina and post-Littoral accumulation terraces, and only a narrow strip along the Bulļupe River belongs to the geomorphological micro-district of the Daugava Valley. Geologically, the area is dominated by Littoral and post-Littoral seas, lagoons and alluvial sandy sediments with wind-blown sand on the surface. Along the sea shore stretches a sandy beach, which is separated from the rest of the area by an irregular forward dune 250–400 m wide. The coast is subject to intensive coastal washing. Quaternary sediments beneath the blankets that the Buļļi are very thick (up to 60 m), located in the Upper Devonian Gauja suites maroon, less sage quartz sandstones with thick aleirolite and clay interlayers. From the engineering geological point of view, the Buļļi area is generally considered to be a homogeneous territory. Most of its territory has favorable conditions for construction, with dense sandy soils (mainly dusty sand with dense interlayers) under the soil to a depth of about 10 meters. In these areas, no special engineering preparations are required for site preparation, although the groundwater level should be carefully assessed, where it is mostly very high () and only in places (in the Southwest and part Northeast) it is naturally deep enough for construction (). Areas less favorable for geotechnical construction are located along Buļļupe coast (around Rītabuļļi), and especially in the SW itself (Vakarbuļļi). There, construction conditions are hampered not only by the composition of the soil, but also by the risk of flooding of the area, which can reach up to 10%, especially in the SW of the island. More than 35.3 ha of the Buļļi neighborhood area has a mandatory need for engineering preparation of the area, if any construction work is carried out there. It should be noted here that in Buļļi it cannot be assessed as a burden for development, because these territories are located in the territory of nature and greenery, where the development of new buildings is
