Lesson 7: Holderness and Swanage Case Study

1
Lesson 7 Holderness and Swanage Case Study

• Lesson Objective
• To produce a detailed case study on an area of
  coastal management

2
MAPLETON- HOLDERNESS

• Mappleton is on the Holdeness coast and the
  cliffs are made of boulder clay and were eroding
  very quickly. The village was in danger, and
  several houses had been lost. However the B1242
  road link was in danger and this made it
  economically viable to build sea defences. An
  offshore bar of granite was built at the cost of
  2 million. This prevented erosion at Mappleton
  but prevented material moving southwards.

3
GREAT COWDEN
At Great Cowden erosion was less than 2m p.a.
until the Mappleton defences were put in place .
In two years, an acre of land has been lost, and
the coast has eroded 80m.

SUE EARLS FARM

• Sue Earle's farmhouse was knocked down in 1997 as
  it was at the cliff edge and was considered
  dangerous. It cost the Earle's 3000 for the
  privilege. They are now suing in court.

Coastal Management Zone (ICZM)

• Planners are trying to find sustainable ways of
  managing the coasts -to reduce the damage to the
  environment.
• Planners are treating the whole of the coastal
  areas from the shore line to several kilometres
  inland (holistic approach)
• Holderness area, Yorkshire is part of the EAST
  RIDING ICZM plan, introduced in 2002
• Set out to protect some areas form erosion and
  other areas do nothing approach taken
• Local people were not happy, they argued the
  local social and economic needs were being
  ignored

What are the options?

• In the UK, local councils pay for sea defences.
  Some may get money from the Government or
  Environment Agency if there is a flood risk.
  There are 4 choices councils can make
• Hold the line? use sea defences to stop erosion?
  EXPENSIVE
• Advance the line? use sea defences to move the
  coast further into the sea? VERY EXPENSIVE
• Strategic Retreat? gradually let the coast erode
  and move people away from risks. This may involve
  compensation for some people
• Do nothing? let nature take its course.
• These choices can cause conflicts. Choices 3 and
  4 will see people loose land, homes and
  businesses. One stretch of coastline may involve
  several choices.
