Involving a SuDS report specialist from the outset will ensure a smooth planning processes, avoidance of delays and fewer costs further into the development.
Discharge Planning Conditions relating to Surface Water run-off from the site
All new developments, regardless of size require SuDS to be incorporated in their design. Whether a minor development requires a SuDS report for validation at planning application stage, very much depends on the requirements of each Lead Local Flood Authority (LLFA). However, as the risk of flooding is increasing regularly, these are being requested by most LLFA’s now, even for minor extensions. The level of detail required by each LLFA can vary, however we are well versed on the varying requirements of each.
As of 2015, national policy mandates that developments of more than 10 units, or commercial/industrial developments classed as major, do require a Flood Risk Assessment and SuDS Strategy report to validate and support the planning application. The level of detail required in these reports can vary dependant on the application type. Less information would be required for an outline application, than for a full application, however essentially the LLFA’s want to see that the SuDS hierarchy has been considered and followed, and that any proposed SuDS will actually be feasible.
Flood risk assessments and a surface water drainage strategy should be implemented into all major developments, and in any development, regardless of size, in a critical drainage area or a high flood risk zone (the Environment Agency considers this Zone 2 and 3).
In the case that you don’t meet any of these criteria, you can still be obliged to carry out a SuDS report by your local planning authorities as they have the final say. It is becoming increasingly important to demonstrate to the Local Planning Authority, the Lead Local Flood Authority and the Environment Agency that surface water drainage has been well-thought-out. It’s best to speak to your local planning office before you submit a planning application.
To confirm if your site is in Flood Zone 2 or 3, we would be happy to assist you, or you can consult these national flood maps:
Is this the only surface water drainage assessment/SuDS report I need? Well, it depends on the location, size and type of the development in question. It also depends on the opinions of the local planning authority and Lead Local Flood Authority.
A second, more in-depth report can sometimes be requested either at planning application stage or to discharge a planning condition. A ‘Detailed Drainage Design’ report provides comprehensive drainage layouts and construction details such as pipe sizes, layouts and connections to existing systems. On-site BRE365 Soakage/Infiltration testing may also be a requirement of achieving planning approval, to confirm feasibility of infiltration and to enable us to calculate the size any proposed soakaway or other infiltration form of SuDS. We provide BRE365 Percolation tests in house, and this allows us to provide this information in short timescales.
Overall, not all planning applications will need a SuDS report, and of those, not all with need a Detailed drainage design, however they can be a stipulation of planning permission. Here at Nimbus, we are here to help and can advise you throughout the planning process, through to construction.
“I have really enjoyed working with Nimbus. Sadia is extremely knowledgeable and is always willing to go out to her way to help clients. The speed at which Nimbus produce their work is impressive and the prices are extremely competitive. Special mention to Ryan Herity after we worked closely together on a couple of schemes. Always happy to pick up the phone and answer questions. He provided solutions that led to drainage officer approvals – you can’t ask any more than that!”
“I have used Nimbus Engineering Consultants for several years now. The service is second to none. Sadia effectively communicates throughout the entire process. Nimbus has never let me down. I would wholeheartedly recommend Nimbus for any and all SuDS advice. Nimbus shoot from the hip, and make my life easy, knowing if I have engaged them, I do not have to ever worry.”
“We’ve collaborated with Sadia on a few projects; Nimbus Engineering’s proposals were well-informed, attentive of regulatory trends and wrapped in proactive attitude.”
We have been working with Nimbus Engineering for some time in a collaborative approach, allowing us to provide our clients with a complete Engineering service. Primarily providing us with SuDs, foul and surface water design, along with highways design and detailing, Nimbus have given us a great service, both prompt and efficient.
We at Rouf Homes have been using Nimbus Engineering for a number of years, for all matters relating to Drainage design, Flood risk and Sustainable Urban Drainage Systems design. We find them to be very knowledgeable on these matters, approachable, efficient and very cost effective
Richardson and Peat Ltd are pleased to be associated with Nimbus Engineering for their work on our Surrey school projects for new autistic teaching centres, with exemplary forward-thinking on the issues facing us with surface water attenuation they have not only dealt with the problems cost-effectively but by detailed design of rainwater gardens and swales have also enhanced the projects. Our company look forward to a continuing working relationship with Nimbus Engineering in the future.
