Abstract
Adaptation to climate change often aims to increase the ability of cities to retain water. In recent years, there has been a shift in the approach to managing storm water from traditional methods to nature-based methods, which view storm water as a valuable resource. This study conducted a systematic analysis of eleven contemporary housing estates that are commonly considered sustainable. The study aimed to identify the elements of rainwater management and determine whether these elements form a system. The research found that, in most cases, not all elements of a rainwater management system (RMS) were present. The housing estates in Gdańsk and Gdynia demonstrated some features of an RMS but were still incomplete due to missing elements such as channels and gaps in curbs that guide rainwater. The results suggest that the implementation of some elements of an RMS does not necessarily create a fully functional system. A fully effective RMS requires the integration of all necessary elements to allow water to flow between them.
