Kategorizace nástrojů prosazování efektivního hospodaření se srážkovou vodou na rozvojových plochách

This paper proposes categorising the tools public administrations can use to support and promote efficient rainwater management on urban and municipal development sites. The overview of tools, their description and classification according to selected criteria was developed as part of a catalogue for the development of software and methodology to support decision-making processes in spatial planning within the framework of the TAČR project SS03010080 (2021–2023). We base our work on published general tool lists and their specifications on rainwater management issues, supported by methodologies for each tool category. The individual groups of tools are complemented by examples from Czech and foreign practice and categorised according to the hierarchical level of public administration, the affected entity and the process stage (planning, implementation, operation) in which the tool is best applied. In total, 18 tools have been distinguished and characterised from five basic categories, i.e. normative, conceptual, coordination and organisational, economic, voluntary and ethical tools. The position of economic instruments in the portfolio appears to be relatively significant, but municipal administrations have limited possibilities of their use, as many of them are tied to national legislation. Based on the characteristics and typology of urban development areas, the appropriate tools for promoting optimal rainwater management design specified in the catalogue will then be recommended using the software and methodology.
