The proposed industrial / housing development at AL6 is largely within an area of agricultural land prone to flooding: it is close to the R. Lavant and susceptible to further damage from rising sea-levels. AL6 does not mention this major risks of rising sea levels , though AL4 specifically mentions the need to avoid the flood-plain of the Lavant in relation to Madgwick Lane. Further, such a development contradicts DM28, there being "adverse impact on the openness of the views in and around the coast, designated environmental areas and the setting of the Chichester Harbour AONB; and the tranquil and rural character of the area. The Salterns Way cycle route would be alongside the development; the much prized peacefulness of the route and the views of the cathedral and Downs would be destroyed. Furthermore, AL6 is adjacent to Chichester Harbour which as previously mentioned is not only an AONB but is a RAMSAR site and SSI. There is evidence of Winter grazing by migratory birds ,including brent geese in the area designated as AL6.
