Flood risk strategy and responsibility

Strategies to manage flood risk around Bristol and who’s responsible for different watercourses such as main rivers, streams, surface water and ground water.

Local Flood Risk Management Strategy

Under the Flood and Water Management Act (2010) we’re designated as the Lead Local Flood Authority (LLFA) for Bristol. This means we’re responsible for managing flood risks from local sources, such as, surface water, groundwater and ordinary watercourses.

In partnership with the Environment Agency, Wessex Water and the Lower Severn Internal Drainage Board we’ve produced the Local Flood Risk Management Strategy (pdf, 12.3MB) (opens new window) . This sets out our plan for better managing flood risks in our area.

Tidal flood risk management

The Central Area Flood Risk Assessment (pdf, 7.2MB) (opens new window) found that, out of the different types of flooding, tidal floods are most likely to cause severe damage to the city centre. The risk of this increases as sea levels rise. We’re working with the Environment Agency, Wessex Water and other partners, to create a tidal flood risk management strategy. This will outline action to be taken to reduce the risk and impact of tidal flooding and how it will be funded.
