THE POTENTIAL IMPLEMENTATION OF STORMWATER RETENTION PONDS INTO THE BLUE-GREEN INFRASTRUCTURE OF THE SUBURBAN LANDSCAPE OF PILSEN, CZECHIA

Abstract

This study investigates the requirements for creating blue-green infrastructure (BGI) as an instrument of stormwater management, in which nature-based solutions in urban and suburban landscapes are preferred. This case study of stormwater retention ponds (SWRPs) in the suburban landscape surrounding the city of Pilsen (Czechia) evaluates selected qualitative parametres of SRWPs on private land. Evaluated SWRPs have been classified according to the ownership relations and the potential indicators of their involvement within the BGI. Although the drain control as a primary purpose of SRWPs is a main criterion of their design, the ponds‘ parameters may differ from each other based on how their nature-based elements are used as well as what their amenity functions in a public space are. Based on the analyses of SRWPs‘ potential, the case study recommends public administration to provide some tools to support the private sector. The economic tools, motivating private sector, must be enhanced. An example of such an instrument could be the establishment of fees for stormwater drainage taking the ecosystem quality of the water management solutions into account.
