What is a Flood Risk Assessment?

As an architect or property developer you’ll need to understand the potential risk of flooding when designing and developing a new or previously developed site. You’ll also need to consider how your site may affect potential flooding nearby.

A Flood Risk Assessment (FRA) will identify and recommend mitigation measures to manage these risks for all stakeholders involved. It is likely you will need to know and understand all of these aspects before you submit a planning application.

Whether for a residential or commercial site, a Flood Risk Assessment identifies these risks and mitigation measures for you. The level of information to document in a Flood Risk Assessment should be specific to the nature of the proposed development.

Do I need a Flood Risk Assessment?

A Flood Risk Assessment is required under the National Planning Policy Framework (NPPF) and the Environment Agency (EA) guidance on development and flood risk when a development is located in Flood Zone 2 or 3,  a Critical Drainage Area, or the site is greater than  or equal to 1 hectare in size, for sites in Flood Zone 1.

You’ll also need a Flood Risk Assessment if your development is taking place within 20 meters of an Environment Agency main river. Environment Agency activity permits will be required if the proposal includes temporary and permeant works within 8m of a EA river and 16m of a tidal EA river.
