Downderry East 2.1
Summary management approach
Allow continuation of the natural slower erosion at Downderry east of Beach Hill, supported by ongoing monitoring. There is a commitment from Cornwall Council to ongoing monitoring of the ‘Action Line’, to provide an ongoing re-assurance to the community. Most recent monitoring indicates maximum erosion of around 300mm over 5 years. Private defences in this section have slowed down natural rates of erosion, though not all local defences have permission and local management activity will be kept under review. Cornwall Council's recently adopted Climate Emergency Development Plan Document (Feb 2023) identifies Downderry and Seaton as a candidate location for adoption of a Coastal Change Management Area within Land Use Planning Policy. This in turn should support the coomunity to identify plans and opportunities to adapt their settlement.
Generic approach assigned to this unit
Management approaches depend on funding and relevant approvals and permissions. Adaptation to coastal change may be needed. If defences are present, some risk from flooding, erosion or ground instability may remain.
Time periods (short (0 to 20 years), medium (20 to 50 years) and long (50 to 100)) are approximate and do not signify precise dates of management transitions.
0 to 20 years (2005 to 2025)

Where the overall intention is for a natural shoreline, not to encourage new defences. In some areas, where specified in the Shoreline Management Plan, works to repair or construct short stretches of defence to provide localised protection (such as to a slipway, access point or isolated properties) may be considered by the Local Planning Authority. All works require relevant permissions.

| Reference Number | Action Description | Action Lead Organisation | Action Progress Status | Priority |
|---|---|---|---|---|
| 17.002 | Monitor erosion rates to improve understanding of risk (including to the coastal path), inform triggers for transition to managed realignment, inform the scale and design of managed realignment. | South West Coastal Monitoring | Progressing | High |
| 17.003 | With reference to the 2018/19 Environment Agency Coastal Community Assessment for Seaton and Downderry and the latest information on flooding and erosion rates, continue to engage with the community and the highways authority on the transition to managed realignment, supporting the designation of this area as a Coastal Change Management Area. | Pending agreement | Not yet started | Medium-high |

The information on this website represents the current SMP management approaches adopted by the local authorities within its area, and current actions needed to deliver them. These management approaches have been approved by the Environment Agency under its Strategic Overview for coastal flood and erosion risk management and are considered to be local policy.
The documents below provide the full SMP adopted locally and approved by the Environment Agency at the time of publication. Some of the information has changed in response to new government policy, new evidence or new work identified.
