Project summary

The Lower Otter Restoration Project (LORP) in Budleigh Salterton, East Devon, is a flagship intertidal habitat restoration, climate adaptation, and infrastructure improvement project delivered by the Environment Agency in partnership with the East Devon Pebblebed Heaths Conservation Trust and Clinton Devon Estates.

LORP has been majority funded by the UK government, with £8.5 million of co-financing from the European Regional Development Fund (ERDF) through the Interreg V A France (Channel) England programme (2021 to 2023). It is the English arm of a cross-border initiative called ‘Promoting Adaptation to Changing Coasts’ (PACCo) and is delivering pre-emptive climate change adaptation in the Otter Valley by working with nature to provide benefits for people and the environment.

As part of the initiative, work is also going ahead on a similar project (Basse Saâne 2050) in the Saâne Valley in Normandy, France. Left unchanged, both valleys’ landscapes would not be sustainable in the face of climate change after centuries of human modification.

The aim of LORP is to demonstrate that it is possible to collaborate with stakeholders in estuarine regions and work with nature, rather than against it, to improve the resilience of coastal communities and their environments.

It is achieving this by increasing flood resilience through greatly improved infrastructure, reversing biodiversity loss (record-breaking levels of wading birds have already been seen regularly in the area since wetland development began), undoing the negative impacts of man-made modifications and restoring significant habitat loss, increasing carbon capture, and building awareness of climate adaptation and nature-based solutions through a range of educational resources and visits. LORP’s unique approach and methodology has also been shared through the publication of the PACCo Guide – a comprehensive framework for nature-based adaptation and management.

The project began in spring 2021 and was completed in early autumn 2023. The works include a 70-meter breach in embankments to reconnect the Otter Estuary to its historic floodplain; restoring 55ha of wetland habitat; the construction of a 30-meter span flood-resilient, raised road and road bridge, as well as a new footbridge over the location of the future breach to ensure continuity of the South West Coast Path; the relocation of Budleigh Salterton Cricket Club away from the floodplain; raising and improving public footpaths, and creating wildlife viewing areas.
