West London Strategic Flood Risk Assessment

What is a Flood Risk Assessment?

A Flood Risk Assessment (FRA) is a report which must accompany certain applications to ensure that the land or property is suitable for the proposed development. They demonstrate how flooding to and from the development will be managed and mitigated both now and in the future, taking the impacts of climate change into account.

Guidance on whether a FRA is required and what it needs to contain can be found on the in the West London SFRA website. Please refer to section 4.2.4 for our Borough specific standard conditions.

If your application does require a FRA, you may need to contact a consultant to prepare it for you.

If your application requires a FRA and you do not submit one, your application will not be validated.

How is the Environment Agency involved?

We consult the Environment Agency (EA) on certain applications. These include:

• applications within flood zones 2 and 3
• any application on a site over 1 hectare in size in flood zone 1
• smaller applications in flood zone 1 which are in areas that have critical drainage issues

Should your application be referable to the EA we will issue the consultation.
