The Southsea Coastal Scheme has now started and will be of interest to anyone passing on or by the seafront whether on land or sea. The existing sea defences which prevent Portsmouth from flooding are now very old and need to be brought up to date. There has been extensive planning of this work to ensure it enhances the visitor experience as well as protecting the island. It will eventually provide improved beach access but the work, costing over £100 million will inevitably cause some disruption.
There is an excellent and very informative website here – have a look at the 3D visualisations on the map too. There will be large barges, dredgers and cranes moving close to the shore, and I expect there will be a lot of sediment distubed in the construction process which may affect fishing. Best advice is: proceed with caution in the area and it’s probably best to avoid the immediate area for fishing if there are boat movements visible.
