Analytical Tool for Risk Assessment of Landscape and Urban Planning: Spatial Development Impact Assessment

This article covers the issue of preventive protection of population, technical infrastructure, and the environment against adverse impacts of careless spatial development. In the first section, we describe the relationship between sustainable development and spatial development. This discussion is followed by a review of the current state of spatial development security, primarily at a national level in the Czech Republic. The remainder of the paper features our original contribution which is a tool for risk assessment in landscape and urban planning, the Spatial Development Impact Assessment (SDIA) tool. We briefly review the most significant semi-quantitative methods of risk analysis that were used as a starting point in implementing the tool, and we discuss several of SDIA's salient features, namely, the assessment process algorithm, the catalogue of hazard and asset groups, and the spatial development impact matrix.
