This location is in flood zone 3

What flood zone 3 means

Land within flood zone 3 has a high probability of flooding from rivers and the sea.

You need to carry out a flood risk assessment (FRA) as part of the planning application for this development.

There is a risk of flooding from surface water at this site. You should check one of the following:

The map shows the flood risk to your site and the surrounding area.

Flood defences

Flood defences have been built to protect against flooding from rivers or the sea (shown as an orange line on the map). Flood defences reduce, but do not completely stop the chance of flooding because they can be overtopped or fail.

What the flood map shows

The flood zones in the map show the areas of land at risk of flooding. They:

  • only show flood risk from rivers and the sea
  • are based on present day flood risk, they do not show how it may change in future because of climate change
  • ignore the effect any flood defences shown could have

Download the flood map for this location

The flood map is suitable for a local planning authority to use when checking a planning application to see if a development is:

  • in flood zone 1, 2 or 3
  • within 20 metres of a main river or a flood defence
  • a water storage area (also likely to be flood zone 3b in the SFRA)

Decide what you need for your planning application

You should:

  • contact Dover local planning authority to check their planning requirements
  • get an FRA, you'll normally need to pay a flood risk specialist to carry it out

Order flood risk data for rivers and the sea

To order flood risk data for this site, contact the Environment Agency team in Kent, South London and East Sussex at ksle@environment-agency.gov.uk

Your email should say that you are ordering flood risk data and include:

  • the address
  • a map showing the site boundary

We aim to email you the data within 20 working days.

Depending on the information that's available, your flood risk assessment data could include:


  • a flood zone map (flood map for planning)
  • historic flood outlines
  • relevant modelled flood levels and extents
  • flood defence locations and attributes

You will also need to assess residual risk from flood defence breach in this location. If available, we will provide breach hazard mapping data to help you do this.

For developments in flood zone 3, your FRA should include an assessment of all sources of flooding and take into account climate change allowances.

Find out how to do an assessment .

We recommend that you check the relevant local planning authority's strategic flood risk assessment (SFRA) as part of your work to prepare a flood risk assessment.
