Pagham Flood Defence Trust has applied to Arun District Council for planning permission for the channel to help reduce or avoid the risk of flood and erosion at Pagham Beach and Haven Church Farm.

A previous application was made in 2015 to ‘alleviate the pressure exerted by the harbour outlet channel along the shoreline and to allow a flux of shingle into Pagham beach shoreline to reverse beach erosion’.
The latest plan has been ‘refocussed’ to ‘avoid/reduce the risk of a tidal breach into Pagham Lagoon with associated flood risk to properties on Pagham Beach and large parts of Haven Church Farm holiday park and avoid/reduce the risk of coastal erosion leading to property loss at the southern
end of Pagham Beach’.

“All these have and continue to impact the natural functioning of the beach and harbour system preventing it from reaching its full natural
potential,” it said.
“The present application recognises this situation and proposes an intervention that does not include any new structures but instead uses a

Since then there had been a breach of Church Norton spit caused by natural processes.
The report said since summer 2018 the outflow channel had been forced into a tighter bend and pushed towards Pagham Spit ‘resulting in significant erosion of the shoreline (Pagham Spit) that led to the breach into the Little Lagoon in summer 2020 and the widespread exposure of the WWII anti-invasion scaffold structure’.

“This leaves autumn 2021 as the only available window to carry out the planned intervention without impacting nesting or overwintering birds.”
