Abstract: This paper contains an interview-based study focusing on permeable pavements as part of sustainable drainage systems. Climate change is causing pluvial flooding, according to the newest IPCC report. This mostly affects urban areas in cities due to: (1) limited capacity of existing drainage systems during heavy-intensity rainfall over a short period of time and (2) limited space for ditches in city areas. Permeable pavements are, therefore, sustainable drainage solutions which combine road infrastructure with water infrastructure. Are permeable pavements a preferable sustainable solution? To answer that question, 24 respondents were interviewed. The interview study was based on a semi-structured interview methodology. A lessons-learned experience was gathered, and the following conclusions were contrived: Firstly, official guidelines on how to construct, consult, and maintain permeable pavements are required. Secondly, more contractors should be able to offer the same product. Finally, official guidelines on the relationship between the contractors are required. These three indicators were extracted from the study.
