Independent Environmental Assessment (Part 3)

The article noted that the ecological well-being of land for construction cottage or location of an existing facility is an important factor in the decision to purchase a specific country estate. The presence near him landfills, existing industrial and agricultural projects, as well as traffic overpasses, soil contamination by harmful substances - these and other factors may influence both the willingness of a private buyer to purchase the object, and its investment attractiveness in general. At the same time, the application developer some technical solutions in the improvement of environmentally safe construction work area may affect the natural balance of the environment and lead to its degradation in the future.
According to state construction standards (GOS) A.2.2-3-2004 cottage-type homes for individual developers, 1-3-storey detached type dwelling houses, 1-3-storey block-type houses with apartments in the different levels relate to the objects of civil 2 First category of complexity, economic and auxiliary buildings for residential homes and garden (summer) houses belong to the 1-st category of complexity. Such objects are technically simple, because for them, provided only a working draft. The structure confirmed part of the working draft should include building materials, assessing the impact of an object on the environment, including data on all of the expected impacts on the environment (land, water and other resources) for their ability to minimize and compensate for construction and operation object.
An informal survey conducted by us developers cottage communities in Kiev and Kiev region demonstrated that in most projects, there is no section on the evaluation of environmental impact assessment (EIA) or environmental protection (EP). According to GSN A.2.2-1 in this section should include an assessment of the environment at the start of construction, as well as a description of possible negative consequences of the construction and operation of facilities in the future. EIA developed based on engineering and environmental, sanitary and engineering surveys and studies using modern techniques and technology. This information should be presented in the form:

1. data on the components of the natural environment (air, groundwater and surface water, soils, flora and fauna) at the time of the working draft and the start of construction works;
2. drawings showing the location of possible external and internal sources of pollution (sanitary protection zones enterprises, transport, overpasses, high-voltage power lines, landfills, local treatment plants, electrical substations, parking of motor transport, etc.) on residential buildings;
3. data on sources of air pollution and measures to minimize such pollution, taking into account physical-geographical and climatic conditions in the area of construction, as well as information on background air pollution;
4. descriptions of technologies used water and waste water treatment, taking into account the impact on surface and underground water sources;
5. assess the impact of construction on the land, including measures to combat the adverse geological events, erosion;
6. information about the presence in the building or nearby objects of nature reserve fund and their protective zones;
7. descriptions of waste management systems of consumption (household and garden and park waste, waste catering, waste, cleaning the streets, etc.) and production (eg, sewage sludge and chemical waste treatment plants).

The introduction of architectural and engineering decisions on planning and landscaping without regard to its natural conditions can lead to irreversible adverse changes in the environment. For example, inadequate accounting for the hydrogeological characteristics of the terrain leads to the fact that in areas with shallow groundwater is often observed basement flooding and water logging adjacent to the buildings of the territory. The reason for this is that during the laying of the foundation has not been taken on the challenge of water, resulting in construction of the foundation was to act as an impermeable barrier to groundwater flow. By increasing the moisture content of soil and building materials creates favorable conditions for reproduction of microorganisms and unpleasant insects.
Activities to change the terrain area, the geometric dimensions of the open water bodies, creation of new reservoirs, etc., require particularly careful evaluation of environmental impact of their implementation. Unfortunately, when deciding on the establishment on the territory of the construction of artificial terraces or transforming the river into the lake developers are guided only by considerations of aesthetics, displaying blatant ignorance in matters of ecology. By the probable consequences of capricious changes in the natural landscape can be attributed, in particular, subsidence and collapse of terraces and alluvial shores, overgrowth and algal blooms in the artificial lakes, destroying the foundations of buildings, etc.
The need for EIA is determined with the participation of state authorities of environmental protection. In any case, the presence of an EIA or environmental protection sections of the working draft of the detailed descriptions of the environment and minimize the possible negative effects demonstrates the seriousness of the designer and literacy, and hence the project owner. To assess the reliability of the data presented in the EIA and the effectiveness of proposed measures to minimize harm to human health and environmental construction, experts of the company "Spano" It is recommended that the study documents the expert group. Such a group must prove their expertise in environmental matters and to be independent of both the government and from those who sells suburban real estate.
