Flood risk – Site situated across numerous flood zones

Where a site is situated across more than one flood zone, the flood zone with the highest probability of flooding, i.e. the worst case scenario, must be considered for the purpose of the BREEAM assessment. An exception to this would be where the areas in the higher probability zone include only soft landscaping and it can be demonstrated that access to the building will be maintained in a flooding event.

This is to ensure that the site has adequately managed the worst case scenario level of flood risk associated with the site’s location.Β
