Many coastal places around the UK face change, with impacts on communities, livelihoods, and landscapes. A tidal surge in 2013 caused significant erosion and flooding on the east coast of England (UK). This was the catalyst for the innovative Bacton to Walcott Coastal Management Scheme, also known as the Sandscaping Scheme, implemented in summer 2019. It is a one-off, large-scale beach nourishment scheme with a design prediction of 15–20 years functional life, the first of its kind in the UK and worldwide outside of the Netherlands. Through stakeholder interviews and a household questionnaire survey, this paper examines the institutional and political challenges, expectations, and hopes associated with this Scheme just before its implementation. The findings indicate that a combination of factors enabled technical and institutional experimentation and innovation at this location: critical erosion risk at a site of strategic infrastructure adjacent to two highly vulnerable villages, extensive stakeholder collaboration across scales, resolute leadership, and recognition of co-benefits. Although most interviewees and local residents foresaw significant benefit from the Scheme—not least respite from the deep anxiety caused by the threat of flooding and erosion risk—tensions were expressed around uncertainty beyond the Scheme’s lifetime and the need to start effective conversations about future adaptation options for the area. This study provides reflections for similar nature-based coastal management schemes elsewhere. It highlights the fundamental challenges facing the governance of natural and social coastal systems for adapting to current and future coastal change and the importance of articulating local and sometimes intangible understandings and expectations of adaptive coastal management interventions.
