Sustainable, economically sound development of the city (settlement) is possible in curbing the spread of its construction and maintenance within the old boundaries. Construction of scattered houses – is highly inappropriate (Expensive) way to create housing that determine the output of biological systems, populations of many organisms and the destruction of large areas of land, large resource costs (construction of new roads, municipal facilities, etc.) and requiring tenants almost compulsory purchase of the car. On the contrary, complex building allows us to construct suitable areas to settle a large number of people and at the same time preserve a significant area of natural landscape. Approximately the same number of inhabitants can be placed, having collected all the housing in a neighborhood, leave the area and the rest in its natural form (if necessary improved) to recreation, farming trees, shrubs, wild birds, to maintain the species composition of plants and animals, the water balance of the territory, etc. The second option significantly (by more than half) of reduced area road surface, the length of water supply, sewerage and other networks. Thus, neighborhood development more feasible than the construction of individual sites.
This is confirmed by the obvious and it is demonstrable benefit options compact development: 1. Housing prices are lower. 2. Fewer bus stops clean, and thus decreases the mass of pollutant emissions. 3. Reduced heating costs in connection with it is less polluted habitat.
4. Halved and more potern land and preserved much of the biochemical relationships of existing ecosystems. 5. Reduced transportation costs, wastes, resulting in also to reduce pollution. 6. Supported by a high ratio of infiltration radio: surface runoff of rainfall and reduced water pollution and groundwater. From the foregoing it follows that the development of a construction of new territories to choose the best option because of its environmental features.
