Coastal Vulnerability Assessments in Newquay – the problem of coastal erosion.

Newquay’s coastline and environment is an important part of the area’s character; much loved and valued by local residents and visitors to the area. It plays an important part in quality of life; leisure pursuits and, of course, in setting Newquay’s position as a tourism destination.

However, the fragility of this particular part of the Cornish North Coast, stretching from The Gannel River to the west, to Watergate Bay in the east, is well documented, with over 20 incidents of landslides, rockfall and slope instability recorded on the British Geological Survey ‘GeoIndex’ database, with particular problems around Tolcarne Point, Tolcarne Beach, Whipsiderry and along the frontage of Watergate Road.

The level of fragility or robustness of Cornwall’s Coastline has been assessed through Cornwall’s Shoreline Management Plan (SMP), and its review in 2016, which notes a general deterioration in the cliffs in the entire parish over the last 15 years, particularly in response to pressure from developers for holiday accommodation and luxury properties overlooking the stunning Newquay waterfront.

In response to this pressure, the Newquay Neighbourhood Development Plan, as implemented in 2019, has formerly designated the entirety of the Newquay Parish coastline (with the exception of the Harbour), as a Coastal Change Management Area (CCMA).

So what is a Coastal Change Management Area?

The CCMA is presented in accordance with Statutory Guidance, as presented in the National Planning Policy Framework (NPPF). The objective of the CCMA is to:

‘To manage the effects of physical change to the shoreline through erosion, coastal landslip, permanent inundation or coastal erosion both as they apply to new development proposals or to existing buildings, roads or other assets which become at risk from the effects of coastal erosion,’ and

To ensure that inappropriate development is not built near the coastal strip, ensuring that any development:

  • Will be safe through its planned lifetime, without increasing risk to life or property, or requiring new or improved coastal defences;
  • Will not affect the natural balance and stability of the coastline or;
  • Exacerbate the rate of shoreline change to the extent that changes to the coastline are increased nearby or elsewhere.

What does this mean in practice?

The success or failure of a planning application in a coastal area of Newquay will very much depend on proximity to the coastline, and projected rates of 100 year erosion.

The Newquay Neighbourhood Development Plan has designated the following zones:

The Exclusion Zone: defined as the anticipated 100-year erosion line identified on the Cornwall Council flood risk interactive mapping website plus a 10m buffer, and

The Coastal Erosion Vulnerability (CEV) Zone: defined as 30m from the landward edge of the Exclusion Zone.

What if my property of proposed redevelopment falls within an Exclusion Zone?

  • Proposals for development in the Exclusion Zone will only be supported where they are for small, temporary structures that will not add to the erosion risk. Residential development will not be supported.

 

  • Proposals for redevelopment, enlargement or extension of existing buildings that fall within the exclusion zone will not be supported.

  • Proposals to change the use of existing buildings into residential usage will not be supported.

 

  • Development proposals that require stabilisation, strengthening or other interference with the cliff will not be supported.

 

What if my property of proposed redevelopment falls within the Coastal Erosion Vulnerability (CEV) Zone?

All development proposals for new build, redevelopment, change of use, extension or enlargement within the CEV zone must be accompanied by a rigorous Coastal Erosion Vulnerability Assessment (CEVA).

Proposals will be supported where the CEVA confirms that the proposal will not cause damage to cliff faces or otherwise increase susceptibility to coastal change and where the proposal complies with all other relevant planning policies.
