Flood Risk assessments
You need to do a flood risk assessment for most developments within one of the flood zones.
This includes developments:
- in flood zone 2 or 3 including minor development and change of use;
- more than 1 hectare (ha) in flood zone 1;
- less than 1 ha in flood zone 1, including a change of use in development type to a more vulnerable class (for example from commercial to residential), where they could be affected by sources of flooding other than rivers and the sea (for example surface water drains, reservoirs);
- in an area within flood zone 1 which has critical drainage problems as notified by the Environment Agency.
You don’t need to do a flood risk assessment for a development that’s less than 1 ha in flood zone 1 unless it could be affected by sources of flooding other than rivers and the sea, for example surface water drains.
More guidance regarding this can be found on the Government website under ‘Flood risk assessments if you’re applying for planning permission’.
If you should need to refer to our Strategic Flood Risk Assessment documents they can be found on the New Forest District Council website by following this link New Forest District Council and New Forest National Park Authority joint Strategic Flood Risk Assessment.
