The South Downs National Park occupies aproximately 70% of the land area of Chichester District. The remaining 30% includes Chichester City with fairly limited opportuniy for major housing sites. The remainder of CDC land area includes Chichester Harbour AONB, which is a RAMSAR site and SSI, Pagham Habour which has SPA staus and Medmerry which is designated as a potential SPA. For Government to require CDC to raise its Local Plan allocation from 435 dwellings p.a. to 609 dwellings p.a. (i.e. by 40%) and then expect CDC to accommodate a further 41 dwelling p.a. from the SDNP is wholly unreasonable. This is particulary so when many Parishes in the SDNP have expressed concern about the sustainabilty of their communities due to the lack of housing for their younger generation.
