New flood risk management policies account for climate and socio-economic change by embracing a more integrated approach. Their implementation processes require: collaboration between a group of stakeholders; combining objectives and funding from various policy domains; consideration of a range of possible options at all spatial scale levels and for various time horizons. Literature provides limited guidance on how to organise a collaborative planning process to devise integrated flood risk management (IFRM) plans. This paper presents a case study where a recently developed framework for process design and management has been used and evaluates whether or not the collaborative planning process led to an IFRM plan. The case study is Dordrecht (NL) where the new multi-layer-safety (MLS) approach has been applied in the context of the Delta Programme. The Delta Programme investigates how the Netherlands can adapt to the effects of climate change. MLS comprises three flood safety layers to reduce flood risk: flood protection, spatial planning, and emergency response. The framework has been shown to be effective in the delivery of an IFRM plan, it has been enriched by defining the interfaces between and phasing of planning activities, and can be further improved to better guide implementation and governance activities.
