About this subsection
For the eastern shore of Portsea Island, the northern shore of Langstone Harbour and the western shore of Langstone, the erosion and flood risk issues are addressed through managing a series of local authority, Hampshire County Council, Environment Agency or privately owned defences. These provide flood risk management to the significant areas of residential, commercial, heritage and industrial development along with associated transport and community infrastructure. Defences on the northern shore at Broadmarsh also provide erosion defence to an area of coastal landfill.
Continued maintenance of these defences results in loss of inter-tidal habitats in an area legally protected for its internationally important wildlife. Opportunities within the SMP area to address this ongoing loss through managed realignment and associated replacement of any lost freshwater features are important considerations for management. Examples of where this approach could be implemented include West Hayling Nature Reserve and parts of Farlington Marshes. In the western central area of Hayling Island the shoreline is allowed to develop more naturally as the erosion rates are relatively low and flood risk limited due to topography.
