Coastal Policy Flashcards
In the UK coastal management
overseen by DEFRA. Since DEFRA introduced SMP in 1995, have been only 4 policies available for coastal management, which differ greatly in costs and consequences.
No active intervention
= no investment in defending against flooding or erosion, whether or not coastal defences have existed previously, coast can do whatever it wants
Strategic realignment
= allow coastline to move naturally but managing the process to direct it in certain areas
Hold the line
build to maintian coastal defences so that the position of shoreline remains same over time
Advance the line
build new coastal defences on the seawards side of the existing coastline, land reclamation.
Making decisions depends on:
- Economic value of assets at risk
- Technical feasibility of engineering solutions
- Cultural or ecological value of land
- Pressure from community and social value of communities
Cost benefit analysis e.g. happisburg in north Norfolk
• The policy adapted in this area is ‘no active intervention’, This is because to defend the village would have an impact on the wider coastal management plan.
• Happisburgh would end up as a promontory, blocking longshore drift and causing further erosion downdrift.
- Longer term, the plan is managed realignment, although this would still involve property being lost to the sea by erosion.
Costs of erosion
• £160,000 could be available to Manor Caravan Park to assist in relocating to a new site
• Affected residents could get up to £2000 each (a total costs of £40-70,000) in relocation expenses plus the cost to the council of finding plots of land on which to build new houses.
• Grade 1 listed St Mary’s Church and Grade 2 listed Manor House would be lost.
- Social costs as the village is slowly degraded, including health effects and loss of jobs
Benefits of erosion
• By 2105, between 20 and 35 houses would be ‘saved’ from erosion, with a combined value of £4 million - 7 million
• 45 hectares of farmland would be saved, with a value of £945,000
• The Manor Caravan Park would be saved, which employs local people.
- The cost of building coastal defences at Happisburgh is around £6 million, very close to the value of property that could be saved, and much higher than the compensation cost payable to local residents.
- Coastal managers argue that Happisburgh must be seen in the wider context of the whole SMP, further justifying the decision not to defend the village
EIA
- Aims to identify the short term and long term on the coastal environment
- Wide ranging and includes impacts on water movement, sediment flow, water quality, changes to flora and fauna.
