Flood Risk Assessment

Why Flood Risk Assessment?

Flood Risk Assessment (FRA) is needed for development proposals which fall into the following general categories:

  • Land located close to or within nationally defined flood zones for the sea, inland tidal channels and fluvial river channels.
  • Sites greater than 1ha in size where surface water run-off needs to be considered.
  • Critical Drainage Areas – areas of difficult drainage, defined by the Environment Agency.

The Government, via Local Planning Authorities (LPA), requires a development to be undertaken in a sustainable manner by managing the risk of flooding to the site and elsewhere for its lifetime. A developer, by way of an FRA, must satisfactorily demonstrate this to the LPA.

England’s Planning Policy Statement (PPS) 25 ‘Development and Flood Risk’ was recently withdrawn but much of it was retained by the replacement National Planning Policy Framework issued in March 2012. Flood Risk must be considered at all stages of the Planning process from Regional Flood Risk Appraisal to Site Specific Flood Risk Assessments.

Why Pristine?

We have built up a good working relationship with key planning organisations, namely, Local Authorities and the Environment Agency and have a comprehensive understanding of their needs and responsibilities.

Pristine provide an extensive range of FRA services individually tailored to suit the scale and nature of the development; including, scoping reports prior to land purchase and full detailed FRA’s required to support a full planning application.

Some projects require Ordnance Survey (OS) data for the site so that accurate comparison of design flood levels and existing ground level can be made. Pristine offers the required survey work, and in all circumstances our policy is to advise clients of particular project requirements at the proposal stage so that the total cost of a project is clear at the outset and fixed price offers can be made.

Where disposal of surface water is of concern we can provide options for suitable drainage systems to accommodate run-off and will endeavour to incorporate Sustainable Drainage Systems (SUDS), wherever possible, in line with national policies and industry guidance.

Working With The Regulators

Pristine encourages early liaison with LPA’s to ensure site specific concerns are identified and suitably assessed in a scope of work which is clear at the outset of a project.

Pristine has extensive experience with working closely with technical consultees in the planning process such as the Environment Agency (EA), to achieve clear results using agreed methodologies and data sources.

Pristine is proud of the ability to bring agreement and understanding to all parties involved to ensure all FRA objectives are met.

Pristine Service Overview

Pristine will complete a site walkover, liaise with relevant regulators and obtain all necessary  information to complete site-specific risk assessments within 4-6 weeks, depending upon the response time from regulators and the complexity of the project.

Upon completion, Pristine will provide a fully illustrated interpretative report, which is sent to regulators and clients, setting out investigation methods, results and recommendations for building design and /or flood protection measures that may be found necessary.

Pristine also take on any negotiation and discussion required in order to obtain approval from appropriate regulatory bodies governing each site.
