Flood Risk Assessments

Contact: floodrisk@arcusconsulting.co.uk

Around 5.2 million properties in England (one in six) are at risk of flooding, while large undeveloped areas are also modelled to flood, meaning  Flood Risk Assessments are becoming a critical part of planning applications.  Early involvement of a hydrologist is key, to avoid project risk.

The Arcus Hydrology team has extensive experience of producing Flood Risk Assessments for a range of development types.  Arcus provides Flood Risk Assessments using best practice methodologies that are fully compliant with the following legislation and guidance:

National Planning Policy Framework (NPPF) for sites in England

Scottish Planning Policy (SPP) for sites in Scotland

Technical Advice Note 15 (TAN15) for sites in Wales

Planning Policy Statement 15 (PPS 15) for sites in Northern Ireland

By agreeing the scope and requirements of Flood Risk Assessments with consultees at an early stage, Arcus has maintained a strong track record in receiving favourable planning recommendations from the Environment Agency (EA), Lead Local Flood Authorities and the Scottish Environment Protection Agency (SEPA).

We work on a variety of scales from large residential and commercial developments to individual households and minor developments.

We use industry standard software such as Micro Drainage and Flood Modeller to ensure our reports and advice comply with guidance, such as the SuDS Manual (C753).

We price our Flood Risk Assessments competitively on a site by site basis and the level of input will depend on whether your site is located within Flood Zone 1, 2 or 3 in England or in a low, medium or high likelihood flood zone in Scotland.  Similarly, the level of input for a Flood Consequence Assessment in Wales will depend on whether your site is located in Flood Zone A, B or C.

To find out more about Flood Zones and whether you require a Flood Risk Assessment, please contact the Arcus Hydrology team to discuss your requirements: floodrisk@arcusconsulting.co.uk
