Flood Risk Assessments and Sustainable Drainage Systems from KB2 Civil Engineering

KB2 's civil engineering projects range from flood risk assessments, design of small housing estate highways to bridges and major roads, below ground and surface water drainage, earthworks, car parks and the detailed analysis of foundations for major building projects and structures.

Flood Risk Assessments (FRA)

The introduction of the latest Planning Policy Statement 25 (PPS25)in December 2006 introduced a requirement for a planning stage assessment of flood risk - an FRA, for all development sites. The FRA must consider the vulnerability of the development, cover potential flooding from all significant sources; sea, river, groundwater, sewers etc., assess risk and determine suitable mitigation measures. Wider issues such as local strategic policies and the effects of climate change also have to be taken into account.

To avoid costly delays we at KB2 recommend that the whole issue of Flood Risk is placed high up the agenda in the pre-planning stage. With our experience KB2 are we ll placed to support and guide Clients through flood related issues and to prepare the necessary FRA’s in support of their planning applications.

We adopt a proactive approach at all stages of development and are experienced in dealing with the necessary statutory bodies to achieve the desired outcome in a timely and cost-effective manner.

Determined to keep within the project deadlines, we offer sustainable and reliable schemes that can be constructed with minimum difficulty. We are aided by the latest computer software such as 'PDS', which offers ground terrain modelling and assists us in the design of roads and highways. We also use in-house programs for developing Sustainable Urban Drainage Systems (SUDS). SUDS designs are to the CIRIA SUDS Manual and the Interim Code of Practice for SUDS.

Sustainable drainage systems (SUDS)

Drainage systems designed on SUDS principles is a major objective of PPS25 and is now often a key factor in successful planning applications. The SUDS concept is based on mimicking the natural water catchment or pre-existing site surface water characteristics. This is achieved by undertaking a pre-development assessment of the site and then applying various strategies for curtailing discharges and pollution, controlling runoff and developing management measures to mitigate any adverse effects of the development

Techniques may involve use of soakaway and ‘SWALE’ features through to rainwater harvesting and below ground storage incorporating flow control devices. By the application of these methods and with KB2’s help a better, safer and more sustainable environment can be created.
