Developers, Don't Delay Your FRA

February 26, 2021

The local planning authority will often request a Flood Risk Assessment (FRA) as part of a planning application.


Our specialists have pulled together the 3 key points below to help you kickstart your FRA, prevent planning delays and get cracking with construction!


Engage Early.


If your site resides in Flood Zone 2 or 3, or covers an area greater than 1 hectare in Flood Zone 1, an FRA is required. Check the Environment Agency’s flood mapping service to see which zone you are in and engage early with an Envireau Water hydrologist to understand the complexity of the project, how much data and technical work is required to support a successful application, and the likely costs. 

Acting early ensures that sustainable solutions are designed to minimise flood risk and manage surface water and, crucially, prevent unforeseen costs and delays during the planning process. 


Understand Your Site’s Hydrology.


The effects of extreme rainfall have led to surface water flooding becoming a more important consideration at planning application stage. Surface water drainage modelling is increasingly required alongside the traditional river or tidal flood risk models, particularly for larger developments. By applying appropriate modelling techniques, concerns around flow pathways and runoff rates can be addressed as part of the FRA.


The modelling is then used to identify sustainable drainage solutions that comply with planning policies and, where necessary, meet the requirements for adoption by the local authority.


Invest in detailed data.


If there is one thing experience has taught us at Envireau Water, it is that the right data is required to make the right decisions! For FRAs, this means investing in a good topographical survey to thoroughly assess the potential for flooding, and design appropriate mitigation where it is required.  Good topographical data can be used to verify the extent of, and where necessary challenge, defined flood zones. Without good data, it is not possible to demonstrate that a development will be safe and not increase flood risk elsewhere.


We can help…


Our team has been carrying out FRAs and developing sustainable solutions for water management and drainage for over 25 years. We apply our expertise in hydrology, hydraulic modelling, and the water environment, to achieve successful outcomes.

Desertification and drought are two of the most pressing environmental challenges of the 21st century. Exacerbated by climate change, the devastating effects of both can be felt across the globe, with an estimated 40% of the world's population impacted by water scarcity events. As global temperatures continue to rise, and severe weather events increase, regions across the globe face the potential for increased frequency and severity of droughts, often progressing rapidly and unexpectedly. As of 29th May this year, a drought was officially declared in parts of the UK, having experienced the driest start to Spring in over 130 years. Whilst the recent rainfall at the start of June has helped to stabilise concerns, uncertainty for the months ahead still remain. How is the UK landscape affected by drought?

Envireau Water is delighted to welcome Tom Onslow to our North Office in Richmond! Tom joined us at the start of the month from Western Australia, where he gained experience working as a Field Hydrogeologist. Prior to this, Tom graduated from Newcastle University with a Master of Earth Science (MEarthSci). Tom is experienced in both field and desk-based activities, including the supervision of water exploration drilling programs, conducting hydrogeological sampling and logging, carrying out pumping tests and analysis and designing and installing groundwater monitoring networks. Tom has also built a strong foundation in technical reporting, having contributed to a wide range of water-related projects, particularly across the mining sector. At Envireau Water, Tom will continue to develop his hydrogeological expertise and provide technical support across a range of sectors both on site and in the office.

As the threat of climate change continues to grow, the occurrence of extreme weather events is becoming increasingly common across the UK, with the rising frequency of flooding and drought posing significant challenges nationwide. After the recent dry spell experienced across the UK, one thing is clear: climate change is a hazard affecting all industries and it is more important than ever for businesses to take proactive steps to secure their water supplies against these unpredictable weather events. We asked our Principal Hydrogeologist, Shona Symon , for her thoughts on the matter within the bottled water industry. Shona, can you explain the importance for operators to safeguard their water bottling plant against the impacts of climate change, and what challenges may arise if not adequately protected?
