The area is located in the eastern part of the Moravian-Silesian Region, to the south/south-east of the city of Trinec, and provides a direct link to the border with the Slovak Republic and Poland.
The I/11 road passes through densely built-up areas of south-west Trinec. The route runs mostly through field landscape, and partly, through rural and suburban built-up areas. Additionally, a small percentage of the areas crossed by the planned road are occupied by forests and watercourses with other vegetation.
The proposal is in accordance with the zoning documentation. Also, the proposed location is in accordance with technical parameters of the following constructions.
PLA Beskydy, as well as populations of birds in the area, will not be affected by the construction of the I/11 road. The route crosses several local wildlife corridors (especially along the riverside) and other significant landscape elements (watercourses, forests). Issues of the TSES elements (Territorial System of Ecological Stability) are resolved by relevant technical measures in accordance with the requirements of nature conservationists.
In terms of the impact of construction on the environment, the most critical part is the meander of the Olza River. The planned route of the I/11 road, which is approved in the municipal plans, passes in this location through the Site of Community Importance of the Olza River (location code CZ0813516) included in the network of nature protection areas NATURA 2000.
There is a need to conserve and protect the following animals and creatures:
- European otter
- European brook lamprey.
In addition to the Olza River, the road crosses several wildlife corridors and other significant landscape elements.
The road passes through a hilly area of altitude 321 - 380 m above sea-level.
In terms of geomorphology, the road segment is, subsequently, located in the province of Western Carpathians, sub-province of Outer Western Carpathians, geological region of West-Beskidian Piedmont and range of Silesian-Moravian Foothills. The major part of the route belongs to the range of larger geomorphological landforms (“Třinecká brázda” and its part “Ropická plošina”). Furthermore, the final part of the route, which is registered in the land register of the municipality of Bystrice nad Olsi, is located in the area of Western Beskids, particularly, in the region of “Jablunkovská brázda” and “Milíkovská plošina”.
The surface structure of pre-quaternary formations belongs to allochthonous flysch units of the nappe system of the Western Carpathians. Geomorphologically speaking, the most dominant sediments are located in tectonostratigraphic units - predominantly, the Subsilesian Unit, the Silesian Unit is represented marginally. Also, made-up-grounds occur in the built-up areas and in the areas of linear structures. Their landscape patterns and thickness are variable. In terms of stability of the territory, there were located three areas, where reduced stability occurred. Therefore, slope deformations are likely to take place in these areas.
