We’re a specialist UK flood and environmental risk consultancy focused toward supporting development and construction projects in multiple sectors including residential, commercial, power, renewable energy and infrastructure. Our experienced ICE engineers and senior consultants can support you with planning, transactional due diligence and risk assessment – they’ve already done it for more than 1,000 projects.
National planning policies require a flood risk assessment or FRA (a flood consequence assessment in Wales) with planning applications for any site over one hectare within Flood Zone 1 – or any development planned for a Zone 2 or Zone 3 flood risk area. We provide a full range of services to test, collate and submit FRAs for any size of development, including those in Critical Drainage Areas (CDAs).
The flood risk assessment must show:
Take a look at official flood maps:
National planning policies can also outline the level of detail you’ll need from your FRA:
Each of our FRAs combines detailed information about previous flood events, considering water from rainfall, groundwater, rivers and the sea. We’ll tailor them to match your requirements and advise you on exactly what you need in each case.
Once you give us your plans for the development of the site, we’ll liaise with the governing body for the country and your local planning authority to assess their exact requirements. We’ll then request the necessary data to assess the flood risk.
At every step we can advise you on design approaches to reduce flood risk. We often act as intermediaries between architects or planning consultants and the Environment Authority, passing on design solutions to strengthen your planning approval application.
Your flood risk assessment for planning purposes will typically consist of a few key elements.
Flood modelling is particularly useful if your site falls within Zone 2 or 3 (medium or high flood risk) and is close to a river, watercourse or drain. We’ll need to visit your site and we can then produce detailed hydrological models of worst-case scenarios, such as breach of flood defences, which can benefit your planning application.
Our detailed flood risk reports and computer-generated models have proved particularly useful for the energy sector. Our experts are familiar with the specific concerns of the industry, including renewable energy, and can advise on all aspects of flood risk for new builds, expansions and existing developments.
We can help you get credits for environmental accreditations to help you gain better management of environmental risks, increased access to new customers and business partners, demonstration of legal and regulatory compliance, and the potential for reduced public liability insurance costs.
If the local planning authority has flagged groundwater as a potential issue, we can develop a detailed conceptual model to assess the risk to the property and design mitigation measures if required.Several London boroughs now require that you assess the impact that a basement construction will have on neighbouring properties and the wider environment. Our concise, site-specific, basement impact assessment reports will put any risk posed by your proposed basement into perspective. Find out more in our blog on the Royal Borough of Kensington and Chelsea.
A sequential test is used to steer new developments towards areas with the lowest possibility of flooding. If your site has not been allocated or tested then you may need to do this as part of your planning application.
This requires a comparative analysis of the flood risk to your development site compared to that of other potential sites that fall within the comparison area. Our consultants can advise you further.
Local planning authorities often ask developers how they will manage surface water for their development. We can provide a sustainable drainage strategies (SuDS) report to satisfy this requirement.
Our reports also include suggestions to help you set up and maintain flood warning and evacuation plans in the event of various levels of potential flooding.
Over the years we’ve developed a good working relationship with each of the governing agencies for each country in the UK. We know the best routes to obtain their data, so we can deliver flood risk assessments both quickly and efficiently.
We liaise with the Environment Agency or relevant governing body to get a better understanding of local flood risk. Once we get the relevant data, we conduct analysis through GIS. Each project is reviewed by a team of qualified professionals. Based on the findings of the analysis we’ll review the results with you and examine the risk of flooding before we proceed.
The EA has a statutory 20 working day turnaround for all enquiries, including data. Sometimes, we can achieve a quicker turnaround depending on the EA’s workload in your area.
Tight timescale? No problem. We can complete a fast-track flood risk assessment to help get your planning application validated, and then complete the full assessment and report when we have all the data from the relevant agency.
Working with an experienced flood risk specialist, you increase your chances of planning approval success.
