Flood Risk Management

Shoreline Management Plan

The coasts of England and Wales are covered by twenty Shoreline Management Plans (SMPs) which are produced by the Environment Agency and other key stakeholders.

The SMP is a non-statutory policy document for coastal defence planning and sets out the recommended approach to managing the shoreline over the next 100 years.

The Cornwall and Isles of Scilly Shoreline Management Plan was last reviewed in 2011 and is currently being refreshed to ensure it remains appropriate and includes any new evidence which may have come to light since then.  


Isles of Scilly Local Flood Risk Management Strategy

Under the Flood and Water Management Act 2010, the Council of the Isles of Scilly, as Lead Local Flood Authority (LLFA) for the islands has a duty to develop, maintain, apply and monitor a strategy for local flood risk management in its area.

The Isles of Scilly Local Flood Risk Management Strategy aims to reduce the number of people and properties at risk, increase community resilience and reduce the social and economic impact of flooding.

Local flood risk is defined as flood risk from surface runoff, groundwater and ordinary water courses, including references to lakes, ponds or other area of water which flows into an ordinary water course. However it is coastal erosion, tidal action and coastal flooding that pose by far and away the most significant flood risk to the islands. It is for this reason that the Local Flood Risk Management Strategy has been expanded to include the threat of coastal flooding. The Environment Agency is responsible for coastal flood and erosion risk management in England.

In partnership with the Environment Agency, we’ve produced the  Local Flood Risk Management Strategy for the Isles of Scilly. This sets out our plan for better managing flood risks in our area.

The Strategy is currently being updated.


Draft Flood Risk Management Plans

The Environment Agency is running a 3 month public consultation on draft Flood Risk Management Plans, from 22 October 2021 to 21 January 2022.

Flood Risk Responsibility

The Environment Agency is responsible for the strategic overview of all sources of flood and coastal erosion risk.

Coastal Flooding & Erosion
The Environment Agency is specifically responsible for coastal flooding and flooding from main rivers (however there are no main rivers on the Isles of Scilly). As the Coastal Protection Authority, the Council has principal responsibility for coastal erosion. 

Surface & Ground Water Flooding 
The Council is responsible for flooding from surface water, ground water and managing the flood risk from Council owned and maintained highways drainage.

Sewers & Water Mains
South West Water is responsible for managing the flood risk from sewers and burst water mains.
