Flood Risk Management

In recent years the importance placed on Flood Risk has increased and it is now an important part of most planning applications. Following the floods in 2007, The Pitt Review, recommended new responsibilities and challenges for local authorities to mitigate flood risk. Richard Allitt Associates Ltd has experience in the production of flood risk assessments for a variety of clients. Our flood risk services include:

FRA - Flood Risk Assessments

An important most of any planning applications these days is the Flood Risk Assessment. We prepare Flood Risk Assessments and (Flood Consequence Assessments in Wales) for large corporate organisations and private individuals in accordance with PPS25, TAN15 and SPP7. We work in conjunction with the client to ensure that all possible mitigation measures are investigated. Examples of some of the studies we have undertaken can be found by downloading the following case studies.

Strategic Flood Risk Assessments

Local authorities are responsible for the production of Strategic Flood Risk Assessments so that potential development sites can be identified. We work with local authorities and other organisations to deliver these Strategic Flood Risk Assessments which can guide development decisions and meet the requirements of planning policy for flood risk. Further details can be found by downloading the following case study.

Breach Analysis

In certain situations it is important to investigate and assess the flood risk if the existing defences fail due to a breach or overtopping. We are able to model flood defence breaches and overtopping using state of the art hydraulic modelling software to enable predictions of the resulting flood extent and provide guidance for the reduction of flooding risk due to such failures. Examples of some of the studies we have undertaken can be found by downloading the following case study.

Surface Water Management Plans

Following on from the 2007 floods, Sir Michael Pitt recommend in The Pitt Review that local authorities undertake Surface Water Management Plans in their area so that areas susceptible to surface water flooding could be identified. Richard Allitt Associates Ltd has been involved in a number of these studies and we can bring our experience in urban drainage and modelling to any project. Examples of some of the studies we have undertaken can be found by downloading the following case studies.

Hydraulic Modelling

Hydraulic models can be used to assess the existing flood risk and the resulting flood risk in the future with climate change or with interventions. We have considerable experience in building and using hydraulic models of sewer networks, river systems and pluvial runoff to assess flood risk. Examples of some of the studies we have undertaken can be found by downloading the following case studies.
