How much is a flood risk assessment?
The cost of a flood risk assessment report is variable based on the size of the land or property being reviewed and the amount of data required to meet the purpose of the report. As a rough guide, a verybasic report would start from £495 plus VAT. A report requiring greater depth of information and requiring more comprehensive and expert interpretation with a site walk over would be in the region of £1,500.
What does a flood risk assessment contain?
A flood risk assessment collates relevant information from a variety of sources relating the proximity of the site to areas that have been modelled as at risk of flooding or have been flooded in the past according to historical records. The risk of flooding via river, coastal, surface water run-off and groundwater pathways are all assessed and the impact a proposed development will have elsewhere on people and property is also considered. The end product is an interpretive report that describes the risk of flooding both to and from the site and meets the requirements set out in the technical guidance section of the current National Planning Policy Framework documentation (formerly PPS25 and SPP7). A site walkover may be required to support the desk study information and provide greater certainty in the report findings. Once all of the relevant data has been collated, site specific Sustainable Drainage Systems (SuDS) options to manage excess storm water can then be assessed if required.
Why commission a flood risk assessment?
Local planning authorities are likely to request a flood risk assessment for any site which is situated on the modelled flood plain and within the vicinity of a fluvial or tidal watercourse. Flood risk assessments are also requested in areas of low fluvial or tidal flood risk if a proposed development is over one hectare in size and/or lies within a critical drainage area. Certain areas are susceptible to groundwater flooding and ESI provide impact assessments for basement construction.
Which report is best for you?
Different levels of flood risk assessment reporting are required for different purposes. ESI has therefore developed a range of products which are suited to the differing needs of our clients.
