Flood Risk Assessments
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 Surface Hydrology team has extensive experience of producing Flood Risk Assessments for a range of development types. Surface 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, Surface 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 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.
