Abstract

Abstract Sustainable urban Stormwater Management (SSM) is currently widely implemented globally to support urban flood management efforts. It is commonly known by terms such as Green Infrastructure (GI), Best Management Practice (BMP), Sustainable Urban Drainage System (SUDS) or Low Impact Development (LID). However, in Vietnam, these approaches are still relatively new and have not been widely adopted due to various barriers, including community perception. Therefore, this study conducted a preliminary social survey in the Thu Duc City area to gain a deeper understanding of perspectives, knowledge, and support for SSM practices. The results showed that among the surveyed residents, 78% favored a centralized stormwater management manner (e.g., retention/detention ponds,…), 51% preferred a decentralized manner (e.g., rain gardens, infiltration trenches,…) and 45% considered household-level practices (e.g., green roofs, rain barrels,…). Additionally, when asked about financial contributions towards implementing these practices, approximately 70% did not support the idea, and 50% believed it was the government’s responsibility. The research findings highlight the diversity in urban residents’ perceptions and opinions regarding stormwater management. This study provides essential foundational information for the development of policies and strategies to effectively promote SSM practices, aiming to mitigate urban flooding and contribute to environmental protection.
