ADVICE TO HOMEOWNERS

The Ventnor Undercliff (including the town of Ventnor and the villages of Bonchurch, St. Lawrence, parts of Niton, and Luccombe) and areas of Cowes and Gurnard (along the northern slopes of the town and village) are built on pre-existing landslide features, which form the distinctive coastal terraces and landscapes of the areas, with implications for the towns and their communities.

Advice and information for homeowners and interested organisations in the areas affected by landsliding and ground movement has been developed. Details and links to this information are provided on this page.

Additionally, information about all coastal areas of the Isle of Wight can be found within the current Isle of Wight Shoreline Mangement Plan, available here (see Main Document -Chapter 4).

Landslide Management:

Detailed geotechnical studies commissioned by the Council have shown that it may be possible to reduce the likelihood and impact of future ground movements in certain situations if a coordinated approach to managing ground instability is adopted.

The actions taken by homeowners and developers on their properties can contribute to the ground stability situation in areas vulnerable to ground movement.

The Isle of Wight Council is continuing to develop policies to manage and mitigate coastal erosion and ground movement problems around the Island's coastline.

 

 

 

1. Cowes and Gurnard

On the northern coast of the Isle of Wight, ground stability issues affect areas of the coastal slopes in Cowes and Gurnard. The following information is available for this area.

2. Ventnor Undercliff

On the south coast of the Isle of Wight, the Ventnor Undercliff is the largest urbanised landslide complex in northwestern Europe. It extends for a distance of 12km from Blackgang in the west to Bonchurch in the east, and includes the town of Ventnor and the villages of Bonchurch, St Lawrence, Niton and Blackgang, It is one of the most scenic parts of the Isle of Wight coastline, arising from its geological history and the ongoing processes of coastal erosion and landsliding. Parts of the area are affected by ground movement.

3. Maps of the Ventnor Undercliff:
Geomorphology, Ground Behaviour and Planning Guidance Maps

A large amount of work has been undertaken over the past two decades investigating the causes of ground movement on the towns and villages and providing information and advice to reduce it's impacts.

Detailed Geomorphology, Ground Behaviour and Planning Guidance Maps are available (1:2,500 scale) for the Ventnor Undercliff area extending from Bonchurch in the east to Blackgang in the west, providing information on the ground conditions, and the suitability for development at the scale of individual properties.

These maps accompany the 1995 Technical Report on the Ventnor Undercliff, available on this page (please see the link above).

For further details, and to obtain extracts of the maps, please contact Isle of Wight Council Engineer: Peter.Marsden@iow.gov.uk (email) or Tel. 01983 821000.

 




 

4. Managing Ground Instability in Urban Areas -Book

Additionally, a book on the management of ground instability illustrates examples of good practice from across the European Union and elsewhere, including sinificant content about the Ventnor Undercliff.

The publication was prepared in 2000 in response to a growing awareness of the need to implement preventative planning and landslide management policies to counter a problem which is likely to escalate as a result of both future development pressures and climate change impacts.
