Barton- on- Sea
Issues
Management
-
Concern that management needed to be improved to protect housing, communities and economic viability of the area
Barton= Rock Armour and rock groynes, while previously slumped material= some protection to cliffs.
Some people have felt that the New Forest District Council was pouring good money after bad and that it was not viable to continue to try to defend a rapidly eroding coastline
-
Chewton Bunny (between Highcliffe and Barton) = channelised to contain water and stop it eroding the cliffs. 2007= major storm= washed away much of this work
2003- Portland stone groynes installed to protect housing at Highcliffe= stronger than wooden groynes, last longer, blend in. have helped build up the beach and appear to be working in reducing cliff erosion
Managed retreat= policy at Barton as geologists recognise the extreme vulnerability of the cliffs here
Rock groyne east of Barton reduces longshore drift and keeps beach profile in place but has the effect of starving the adjacent coastline to the east of material, increasing erosion of the farmland and reducing the supply of shingle to Hurst Castle Spit, which is now threatened by erosion

Holiday village at risk of being destroyed. caravans can be moved and chalets= lower economic value than houses= explains decision to allow cliff retreat
Groynes have the effect of starving the adjacent coastline to the east of material, increasing erosion of the farmland and reducing the supply of shingle to Hurst Castle Spit, which is now threatened by erosion
