Seagrove Bay and Seaview
- Crumbling sea wall and unstable slope.
- Chose to 'hold the line'.
- Scheme cost just under £1 million and was completed in 2000.
- New concrete sea wall, wiht 200m of rock revetment placed in front of the wall to dissipate wave energy.
- Rock Gryones.
- Land Drainage, significantly reduced mass movement of soft clay.
- Scheme cost £4.7 million and was completed in 2004.
- Consists of 550m stone faced conrete sea wall and rock revement.

- Ageing sea wall, in danager of collapse which would reactivate landslides.
- Property on the cliff was becoming unstable.
- Scheme completed in 2000 costing £1.6 million.
- Rock Revement - 15000 tones of Norwegian granite placed seawards.
- Coastal slopes were regraded to make a shallower profile before installing land drainage.
- Lead to a recovery in property values.

- Cliff failure resulting froma combinatation of high energy destructive waves and high rainfall.
- Scheme costed £1.4 million, however the value of property exceeded this.
- The scheme was completed in1992 but sedimentation of the rock gryones has been a problem.
- offshore breakwater has been put in.
- 6 rock gryones and a rock revement to reinforce the exisiting sea wall using 25000 tonnes of Norwegian granite.
- Beach nourishment using 40,000m^3 of sand and gravel, re-profiling the slope and installing land drainage.

East of Freshwater
- Where the A3055 passes over a chalk ridge at Afton Down it is now within 11m of the cliff edge.
- Sea defences would be econonmically unjustified and environmentally unacceptable.
- Stabilises the cliff top by anchoring the tope of the cliff face costing £750 000.

- Coast protection and Slope Inprovement schem cost £6.2 million and was completed in 2004.
- Included 500m rock revement, extension system of drainage pipes and syphon drains reducing surface and groundwater levels, reducing landslides.
5 of 7
- Existing wooden revetment were becoming progressively ineffective as the clay cliffs retreated.
- Property value in excess of £10 million was increasingly at risk as coastal processes activated ancient landslides.
- Land drainage was installed.
- Stabilising the slopes with thousands of tones of chalk.
- Rock revetment of Somersel limestone, aconrete walkway and a gabion wall.
- Scheme costed £2.3 million and was completed in 1996.
6 of 7
- High energy waves were removing chalk blocks which protectedan acient landslide complex upoon which houses had been built.
- There was danger of landslides being reactivated.
- 31.2 million of Carboniferous limestone was brought in to construct 1 700m long rock revetment along the base of the cliffs using blocks weighing 6-8 tones.
- Limestone rock gryones were also constructed at 100m intervals at the base of the cliff.
