Screening assessment of environmental risks when selecting road routes The methodology deals with the early determination of potential environmental risks of new road variants, at the very beginning of investment preparation. Using a formalized procedure in GIS, a series of background maps suitable for the design of various route variants by the designer and a set of indicators for assessing their acceptability in terms of environmental impacts are designed. The assessment is based on environmental legislation, the specific local situation and a comparison in the broader context of the Czech Republic. For this purpose, two series of indicators were developed that allow the construction to be assessed in the context of (a) types of territories in the Czech Republic and (b) other analogous road constructions.
The methodology can be used both in the initial selection phase in the screening phase and in the assessment phase in the EIA process. The target group is workers involved in the assessment of the impact of road construction on the environment, road designers and investors, spatial planning workers, state administration officials and other participants in the preparation process.
