SOSCA is an alliance of individuals and groups involved in promoting the environment, community, and economy of Chichester’s coastal plain. Our district is one of the most beautiful destinations for residents and visitors on the south coast but its unique and fragile environment is under threat from both overdevelopment and climate change. As guardians of an area steeped in history and containing some of the south’s most important wetlands and wildlife habitats, we have a duty to safeguard the Chichester coastal plain for future generations.




We recognise there is a requirement for more housing.  What is not wanted is market led housing of high prices or housing for second homes.  What is needed is housing that is well built, sustainable, and affordable either to buy or to rent. And for local democracy through communities and local government to determine what is needed and where.





The imposition of a new system which gives priority of developers over communities and imposes a blanket ‘algorithm’ to determine the numbers and where they should be built.  The whole planning process would then be determined by central committee within Whitehall.  This process would take NO ACCOUNT of the damage to the environment or consequences of climate change.  It would result in the coalescence of the whole of the south coast and destroy the very environment the government is constantly saying it is protecting.




The Alliance has built up a wide and inclusive support from parishes across the Chichester Coastal Plain and others. Langstone, Emsworth & Westbourne, Southbourne & Nutbourne, Chidham & Hambrook, Bosham, Fishbourne, Donnington & Stockridge, Hunston, Mundham, Aldmonington, Sidlesham, Oving, Tangmere, Pagham,  Selsey Town, East Wittering & Bracklesham, West Wittering, Birdham, Itchenor, together with their many environment groups, residents’ associations and other local organisations. The Alliance works closely with Chichester Harbour Trust, CPRE Sussex, CPRE Hampshire, and other major national organisations. The Alliance has support across the whole of West and East Sussex, Hampshire, Surrey, Kent, and parts of South London.
