Are You Carrying Out Activities Close to a River?

April 23, 2020

In England, Flood Risk Activity Permits are required by law when activities are being carried out which may affect main rivers, flood plains, flood defences and tidal/sea defences.

You may need a permit if you are doing any of the following:

  • Any activity within 8 metres of the bank of a main river, or 16 metres if it is a tidal main river
  • Any activity within 8 metres of any flood defence structure or culvert on a main river, or 16 metres on a tidal river
  • Any activity within 16 metres of a sea defence structure
  • Activities carried out on the floodplain of a main river, more than 8 metres from the riverbank, culvert or flood defence structure (or 16 metres if it is a tidal main river), if you do not have planning permission


View the government regulations and guidance here. There are similar regulatory requirements in Wales, Scotland and Northern Ireland.


What do you need to do?

The first step is to check if your site is close to a main river by visiting the Environment Agency’s Main River Map and typing in your postcode. If your site is within the specified distance, then a FRAP may be required. Applications can take months to be processed and determined, which is a real stumbling block to projects that may already be on hold or delayed due to Covid-19.


If your site is close to an ordinary watercourse that is not designated as a main river, then you need to contact your local council and/or drainage board to discuss the requirements.


What FRAP do I need?

There are two permits that you can apply for:


  • Standard rules permit- this applies if your works are fully covered in the list of standard activities defined by the Environment Agency.
  • Bespoke permit- this applies if your works do not fall wholly within the list of standard activities. More complicated process.


If your activities require a bespoke permit you must carry out a risk assessment which considers the potential impact of your work on flood risk, drainage and the environment. You must also develop a management system which shows how you will manage any risks. It’s important, especially at present, that any supporting documents are prepared in a clear and concise way, to enable the Environment Agency to determine applications efficiently.


There’s good news

Government organisations such as the Environment Agency continue to function during the lockdown, which means this time could be used productively to submit your permit application and allow your project to progress as soon as possible.


Envireau Water staff are on hand to fully assess the regulatory requirements at your site, produce the relevant technical work, manage the application process and liaise with regulatory authorities to obtain the necessary permit. We are here to support our clients and simplify the process, take a read of the following recent case study to see for yourself.

We're always excited to see our team grow, and we are thrilled to welcome Hannah to the team. Hannah joined our Scotland office at the end of June to gain some hydrogeological experience alongside completing her university studies, and we look forward to welcoming her officially in September where she will begin her career as a Hydrogeologist. Prior to joining, Hannah completed a BSc in Environmental Sciences at University of Glasgow and is currently working towards completing an MSc in Hydrogeology at the University of Strathclyde. During her masters and undergraduate degree, Hannah has participated in various fieldwork activities where she developed an in-depth understanding of applied hydrology, soil analysis and mapping techniques.

Our team just keeps on growing and we are delighted to welcome Rob Pickersgill as our newest member! Rob joined us at the end of June, bringing extensive experience across both hydrology and civil engineering, with a particular focus on hydraulic modelling, Flood Risk Assessments (FRAs), and Discharge Impact Assessments. Rob's academic background stems from the University of Nottingham, where he completed a MEng in Engineering, followed by an MSC in Global Urban Development and Planning at the University of Manchester. Rob joins our specialist surface water team and will be based at the RSK Group office in Bristol, providing hydrological services to a range of projects for our diverse client base, primarily within the development sector.

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.
