Barton-on-sea

1. Stakeholders

   • Cafe owners
     • car parking spaces have been cordoned off
     • no engineering in place - want sea wall
     • part of beach is inaccessible
   • Property owners
     • want more than just managed retreat
     • house won't sell
     • pay taxes to council to maintain area
   • local councillors
     • managed retreat
     • money should be spent on other things
     • ineffective hard engineering previously
   • Nash holiday village
     • want hard engineering
     • area is dangerous and fenced off - have to move mobile homes from cliff edge
   • Conservationists
     • natural approach
   • Engineering companies
     • managed retreat only option due to geology
     • Groynes at Bournemouth starving Barton's beaches

2. Coastal management

   • Hard engineering
     • 1964 - New forest council spend 1 million on protecting 1800m with 16 wooden groynes, cliff draining system, rock armour and steel piles
       • failed - large slumping events
     • 1985 - wooden groynes replaced with 7 rock armoured groins (more durable and cost efficient reducing LSD)
     • 1991- timber revetments replaced by 1800m long rock revetment designed to last 30 years
     • 1995 - fan shaped drains put in cliff and cliff regraded
     • 1974 - timber revetments put in
   • Soft engineering and Managed retreat
     • vegetation defences - slow cliff retreat and prevent slumping
     • 2007 - some areas protected by beach nourishment
     • new building on coast built with improved drainage to reduce ground water build up

3. Effects

   • Social effects
     • lost homes
     • reduced access for recreation - loss of money (clifftop path closed due to slumping)
   • Economic effects
     • businesses such as clifftop cafe lost
     • buildings in barton court will be lost within 10-20 years - reduces market value
     • beach access road closed - reduces visitors and money for economy
     • Naish holiday park - regularly has to move mobile homes away from edge
   • Environmental effects
     • beach, cliff and woodland habitats threatened by movement

4. Causes

   • Physical causes
     • Rock type - slumping due to water sitting on top of impermeable cliff
     • Large fetch
       • destructive waves with high energy hit soft cliffs
     • Rising sea levels
       • storminess - waves hit soft rock
       • abrasion and hydraulic action
   • Human causes
     • Coastal management
       • groynes at Bournemouth starve beach of sediment
     • Offshore dredging
       • starves Barton of sediment
     • Human settlement
       • Buildings load slope
